Description

The present invention is a cyclone-type solid-liquid system that separates used coolant (dirty liquid) containing residue (chips) discharged from machine tools such as lathes and milling machines into residue and coolant (clean liquid) for reuse. Regarding a separation device.

Various devices and methods are used to separate used coolant (dirty liquid) containing residue (chips) discharged from machine tools such as lathes and milling machines into residue and coolant for reuse (clean liquid). One of them is a solid-liquid separator using a cyclone (hereinafter referred to as a cyclone solid-liquid separator).
This cyclone type solid-liquid separator has the features of simple structure, small size, and large processing capacity, so it is not only used for solid-liquid separation of coolant used in machine tools, but also for many applications. It is used for various purposes in the field, such as classifying, concentrating, and collecting particles, and the solid to be separated is the "target object", and the liquid containing the solid is the "carrying fluid", and the target object is the "target object". The mixture of the carrier fluid and the carrier fluid is a solid-liquid mixture.
Various techniques have been disclosed for improving the separation performance by making improvements to the target object collection section, which is usually located below the cyclone type solid-liquid separator.

For example, in Patent Document 1, the problem is to provide a cyclone that collects single micron particles with high collection efficiency, and as a means of solving the problem, a cylindrical upper barrel 4a and an inverted conical lower barrel 4b are disclosed. a cyclone body 4 having a cyclone main body 4, an inlet 8 for introducing raw materials and fluid, a top plate 4c that covers the upper edge of the upper barrel and has an opening 12 in the center, and a top plate 4c that covers the upper edge of the upper barrel and has an opening 12 in the center; a first discharge port 10 that is inserted into the opening and raises the fine powder and fluid separated from the raw material and fluid by the swirling motion of the raw material and fluid and discharges it from the cyclone body; and the coarse powder and fluid obtained by the swirling motion. a second discharge port 4f for discharging the powder from the lower end of the lower body cylinder; a collection box 6 connected to the lower part of the second discharge port for collecting coarse powder and fluid; and a collection box 6 for collecting coarse powder and fluid from the collection box. The cyclone device 2 is equipped with an underflow mechanism 7 for causing underflow, and a hollow section 16 is formed in the upper part of the collection box, the upper end of which is connected to the second discharge port, and which has a substantially truncated conical shape that spreads downward. A cyclone device is disclosed.

Furthermore, Patent Document 2 aims to provide a solid-liquid separator that can improve the separation efficiency of solids in a space-saving manner, and as a means of solving the problem, raw water containing solids is swirled and centrifuged, and solids are separated by centrifugation. A centrifugal separator 3 having a slurry discharge pipe 5 at the bottom for discharging slurry containing substances to the outside, and a treated water discharge pipe 7 for discharging treated water to the outside at the top; a raw water tank 2 for storing raw water; a water pump P1 that pumps raw water from the raw water tank to the centrifugal separator; a collection pot into which a slurry discharge pipe of the centrifugal separator is inserted, and which sediments solids contained in the slurry discharged from the slurry discharge pipe in the form of sludge; 6, 6A, 6B; a supernatant discharge pipe that is inserted into the upper part of the collection pot and discharges the supernatant water of the slurry in the collection pot; and a sludge discharge pipe 8 that discharges the settled sludge at the lower part of the collection pot. A solid-liquid separator is disclosed in which a gap is provided between the lower end 5e of the slurry discharge pipe and the bottom 6b of the recovery pot, and the lower end 5e of the slurry discharge pipe is located lower than the lower end 7e of the supernatant discharge pipe.

However, in the cyclone type solid-liquid separator, even if the above-mentioned prior art is combined, if the solid-liquid mixture is not in a state where the solid-liquid mixture is fed under pressure to form a swirling flow and an appropriate centrifugal force is generated, This does not solve the problem that the target object and the carrier fluid are not separated properly and the solid-liquid mixture is deposited in the collection area of the target object.
If the solid-liquid mixture is not being pumped under pressure to create a swirling flow and an appropriate centrifugal force is not being generated, it may occur immediately after the cyclone type solid-liquid separator is started, or after the pressurized pumping of the solid-liquid mixture is finished. This is assumed to be the case.
In addition, as shown in Figure 9, conventionally, a removable collection container is provided in the collection part of the target object, and when the target object and solid-liquid mixture settle in the collection container, the collection container can be removed as appropriate and separated. A complex discharge mechanism such as a conveyor device is installed below the cyclone type solid-liquid separator to remove falling objects and solid-liquid mixtures. The structure was such that it discharged.

JP2016-41398A JP2015-205278A

However, with the above-mentioned means, it is necessary to replace the storage container each time, which is inefficient and undesirable from the standpoint of environmental burden. In the case of a configuration in which a discharge mechanism such as a conveyor device is provided, the mechanism becomes complicated, and the number of parts and size of the entire device inevitably increases, and the processing capacity of the cyclone type solid-liquid separator is limited despite its small size. This cancels out the advantage of being expensive.
In recent years, powdered quartz, which is discharged as a solid-liquid mixture after processing quartz glass, which is essential for the manufacture of semiconductors, has become stuck in the discharge mechanism of conveyors and other devices, hindering smooth discharge and work. Put it away.
Therefore, in the present invention, in addition to suppressing the environmental burden, a simple discharge mechanism enables smooth solid-liquid separation in a small space without increasing the number of parts or increasing the size of the device, and highly efficient recovery of the target material. To provide a possible cyclone type solid-liquid separation device.

The cyclone solid-liquid separator of the present invention has a supply port that supplies a dirty liquid containing residue discharged from a machine tool such as a lathe or a milling machine into the apparatus at a predetermined pressure, and a swirling flow generated inside the apparatus to remove the residue. a main body portion having a clean liquid discharge port from which the clean liquid separated from the liquid is discharged, a residue discharge port at the lower end from which the residue and a portion of the dirty liquid are discharged, and a first storage communicating with the residue discharge port. and a second housing part, which is a through hole, is arranged below the first housing part and forms a continuous hole shape with the first housing part, and is arranged in a substantially horizontal direction. A residue storage/discharge mechanism is provided which forms a storage hole having a concave cross-sectional shape by a slidable sliding member and a bottom member disposed to form a bottom surface of the one continuous hole shape, The ejection mechanism has an accommodation mode in which the first accommodation section, the second accommodation section, and the bottom member form a single continuous accommodation hole with a concave cross section, and a sliding member that is removed from the accommodation configuration. It slides in a substantially horizontal direction so that the second accommodating part protrudes from the end of the bottom member to discharge the residue and part of the dirty liquid deposited in the second accommodating part downward. It is characterized by changing its form.
Further, in the residue storage and discharge mechanism in the cyclone solid-liquid separator of the present invention, the first storage part is a tubular body communicating with the residue discharge port, and the sliding member is a second storage part having a through hole in the side surface. The piston is a cylindrical piston with a cylindrical piston, which includes the piston so as to be able to slide in a substantially horizontal direction, and which prevents the formation of the one continuous hole shape on the side surface that is the connection part with the first housing part. It is characterized in that it is a cylindrical cylinder that is provided with a hole for removing the liquid and forms a bottom member in the housing configuration.

Further, the residue storage and discharge mechanism in the cyclone solid-liquid separator of the present invention includes a first layer plate provided with a first storage portion that is a through hole communicating with the residue discharge port, and a first layer plate provided with a first storage portion that is a through hole communicating with the residue discharge port. a second layer plate connected to the lower part of the plate and provided with a second accommodating part, which is a through hole; and a second layer plate connected to the lower part of the second layer plate to form a bottom surface of the second accommodating part. The second layer plate is arranged to be able to slide approximately horizontally between the first layer plate and the third layer plate, and the second layer plate is provided on the first layer plate. The first housing part is a through hole provided in the second layer plate, the second housing part is a through hole provided in the second layer plate, and the third layer plate forms a single continuous concave housing hole. When the second layer plate slides from the housing configuration, the second housing portion, which is a through hole provided in the second layer plate, protrudes from the end of the third layer plate, and the second layer plate slides from the housing configuration. It is characterized in that the form is changed to a discharge form in which part of the residue and dirty liquid deposited in the second storage part is discharged.
According to the present invention, although the configuration is very simple, the amount of dirty liquid discharged together with the residue can be suppressed to a minimum, and the dirty liquid stored (sedimented) in the first storage section can Since the internal pressure is maintained, effective residue discharge is possible even during solid-liquid separation work.

The cyclone type solid-liquid separator of the present invention has a housing configuration in which the first housing part, the second housing part, and the bottom member of the residue storage/discharge mechanism form one continuous housing hole having a concave shape. According to the present invention, the hole has a substantially conical shape in which the inner diameter gradually increases from the top to the bottom. The amount of dirty liquid stored in the first storage part to maintain internal pressure (internal pressure) can be reduced, and a large amount of residue can be stored and discharged, reducing the frequency of residue discharge work. You can do less.
The side wall of the second storage section has a tapered shape with a wide opening downward from the information side, which minimizes the adhesion of residue to the wall surface during discharge and enables smooth residue discharge. .

The cyclone type solid-liquid separator of the present invention is designed to maintain internal pressure at the lower part of the main body near the residue outlet so that the liquid level of the dirty liquid deposited in the lower part of the main body and the storage hole is at a predetermined height.

(First embodiment)
DESCRIPTION OF THE PREFERRED EMBODIMENTS A detailed description of an embodiment of the present invention will be given below based on concretely illustrated drawings.

(About cyclone solid-liquid separator)
FIGS. 1 and 2 are a perspective view and a front view schematically showing a cyclone solid-liquid separator 1 according to a first embodiment of the present invention. The central portion M has a funnel shape with the inner diameter decreasing toward the bottom, and the lower portion B has a tube shape with an opening O at the lower end Be. The inside of the central part M of the main body part 10 is approximately funnel-shaped like the outside, and on the upper side surface there is a target material (in this case, a target material that is discharged after being used as a coolant in machine tools such as lathes and milling machines). A supply port 100a is disposed for supplying a solid-liquid mixture (referred to as dirty liquid L1 here) mixed with residue A clean liquid discharge port 100b is arranged to discharge a conveyed fluid (here, referred to as clean liquid Lc). The lower end Be of the lower part B of the main body portion 10 serves as a residue discharge port 100c for discharging the residue X separated from the dirty liquid L1.
In the cyclone solid-liquid separator 1 according to the present embodiment, when the dirty liquid L1 mixed with the residue X is poured into the main body 10 from the supply port 100a by a pressurizing means such as a pump, a swirling flow (cyclone) is generated. , the dirty liquid L1 is separated into the clean liquid Lc and the residue X due to the difference in mass (specific gravity) between the liquid and the solid, and the clean liquid is discharged from the clean liquid discharge port 100b, and the residue X is discharged from the residue discharge port 100c. Ru.
The main body 10 may be a known device, and the capacity of the main body 10, the supply rate of the dirty liquid L1, etc. can be selected as appropriate.

(Overview of residue storage and discharge mechanism)
A residue storage and discharge mechanism 20 is connected below the residue discharge port 100c from which the residue X separated by the main body 10 of the cyclone solid-liquid separator 1 is discharged.
As shown in the cross-sectional views of FIGS. 3 and 4, the residue storage and discharge mechanism 20 in this embodiment includes a joint 200a that is a tubular body that communicates with the lower end Be of the main body 10 of the cyclone solid-liquid separator; The piston 200b is arranged below the piston 200a, and the cylinder 200c includes the piston 200b so as to be slidable in a substantially horizontal direction.
The joint 200a constituting the residue storage and discharge mechanism 20 is a tubular body that has an opening facing the inner diameter of the lower end Be (residue discharge port 100c) of the main body 10 and extends vertically downward. It has a substantially conical shape in which the inner diameter gradually increases from the side connected to the residue discharge port 100c downwards (towards the piston 200b and cylinder 200c). Here, the space formed inside the joint 200a is referred to as a first housing portion H1 (see FIG. 3).
Next, the piston 200b is a cylindrical sliding member disposed so as to be slidable in a substantially horizontal direction below the joint 200a, and has a side surface that corresponds to the inner diameter of the lower end of the joint 200a, and an inner diameter that gradually increases vertically downward. A through hole is drilled to increase the size of the hole. This through hole (the space formed by it) is defined as a second housing portion H2 (see FIG. 3). As shown in FIG. 3, the first accommodating part H1 and the second accommodating part H2 are arranged on the coaxial line A, so that a single continuous concave-shaped accommodating hole H is formed. When the piston 200b slides as shown in FIG. 4, the second accommodating part H2 protrudes from the end of the cylinder 200c, which will be described later, and collects the residue X deposited in the second accommodating part H2. The state of discharging into container D is defined as the discharge form.
The piston 200b is provided with an O-ring and a "barb" for tight contact with the cylinder 200c to prevent leakage or infiltration of the dirty liquid L1 during sliding (Fig. 5, (See FIG. 6), however, known techniques can be selected as appropriate for the means.
The cylinder 200c is connected to the lower end of the joint 200a, has a through hole on its side surface that corresponds to the inner diameter of the lower end of the joint 200a (first housing part), and is capable of sliding the piston 200b in a substantially horizontal direction. The cylinder 200c is a cylindrical member contained in the housing hole H, and in the housed state, the cylinder 200c plays the role of a bottom member forming the bottom face of the housing hole H.
Here, the transition between the storage mode and the discharge mode, that is, the sliding of the piston 200b, may be performed manually or automatically under electrical control.

(Effect of residue storage and discharge mechanism)
Immediately after the cyclone type solid-liquid separator 1 is started, the dirty liquid L1 is supplied under pressure from the supply port 1a into the main body 10, but until a sufficient swirling flow is generated, the solid-liquid separation continues. A part of the dirty liquid L1 falls toward the lower part B of the main body part 10 without being prompted, and is captured in the accommodation hole H in the accommodation state in the residue accommodation and discharge mechanism 20.
Next, when an appropriate swirling flow is generated inside the main body 10 and solid-liquid separation of the dirty liquid L1 is promoted, only the residue X settles and is accommodated in the accommodation hole H, and the clean liquid Lc becomes the clean liquid Lc. It is discharged from the discharge port 1b, returned to the machine tool, and reused as a coolant (see FIG. 1).
Here, in the accommodation hole H, due to the difference in mass (specific gravity), the solid residue X, which is mineral or metal powder, is deposited in the lower second accommodation part H2 formed in the piston 200b. , most of the liquid accumulates in the upper first storage portion H1 formed in the joint 200a (see FIG. 5).
Then, when the residue X deposited in the second accommodation part H2 of the accommodation hole H reaches a predetermined amount, the piston 200b is slid to discharge the residue X. As a result, the side surface portion of the piston 200b where the accommodating portion H2 is not formed forms the bottom surface portion of the accommodating portion H1 formed in the joint 200a (see FIG. 6).
By employing the residue storage and discharge mechanism 20 of this embodiment, unlike the conventional method used to discharge residues, even when the residue X is discharged by sliding the piston 200b, the first storage section H1 Since the dirty liquid L1 remains without being discharged, the residue can be discharged without changing the internal pressure of the main body portion 10. That is, even when a swirling flow is generated and solid-liquid separation is being performed, the residue X can be discharged without reducing work efficiency or work accuracy.
Furthermore, the amount of the dirty liquid L1 accommodated in the accommodation hole H and discharged together with the residue X can be suppressed, and the residue X can be efficiently discharged.
Here, in order to grasp the amount of residue Yes (not shown).
Furthermore, when the supply of the dirty liquid L1 into the main body 10 is completed, a sufficient swirling flow is not obtained, as is the case when starting the apparatus, so that solid-liquid separation of the dirty liquid L1 is not promoted and the main body 10 It falls downward B and is captured by the accommodation hole H which is in the accommodation form.

(About the shape of the storage part)
As for the shape of the accommodation hole H provided in the residue accommodation and discharge mechanism 20, it is desirable that the shape of the accommodation hole H is approximately conical, with the inner diameter gradually increasing from the top to the bottom from the joint 200a to the piston 200b (see FIG. 7).
This reduces the accommodable volume of the first accommodating portion H1 compared to a simple cylindrical shape, and directs the dirty liquid Lc in excess of the accommodable volume to the lower part B of the main body 10 where it is affected by the swirling flow. By increasing the storage capacity of the second storage section H2 than the first storage section H1 and accommodating as much residue X as possible, the number of residue discharge operations can be reduced. This is to give the role of
In addition, since the side surface of the accommodation hole H (H2) is angled (tapered) so that the bottom is wider, the residue X remains attached to the accommodation hole H (H2) when the residue X is discharged. It is also possible to expect the effect of preventing this from occurring and completely discharging the residue X in the accommodation hole H (H2).

(Second embodiment)
The second embodiment of the present invention will be described in detail based on the drawings specifically illustrated as follows.

(About cyclone solid-liquid separator)
8 and 9 are a perspective view and a front view schematically showing a cyclone solid-liquid separator 2 according to a second embodiment of the present invention, and the structure of the main body 10 and the solid-liquid separation method are as follows. Since this is the same as the first embodiment described above, detailed explanation will be omitted.

(Overview of residue storage and discharge mechanism)
A residue storage and discharge mechanism 21 is connected below the residue discharge port 101c from which the residue X separated by the main body 10 of the cyclone solid-liquid separator 2 is discharged.
As shown in the cross-sectional views of FIGS. 10 and 11, the residue storage and discharge mechanism 21 in this embodiment is composed of three layers of plates, from top to bottom: a first layer plate P1, and a second layer plate P2. , the third layer plate P3. The first layer plate P1 connected to the lower end Be of the main body 10 of the cyclone type solid-liquid separator 2 and the second layer plate P2 have a cone whose inner diameter gradually increases from above to below over the two layers. A shaped hole (accommodating hole) is formed, and the diameter of the opening Ho of the accommodating portion H1 on the upper surface of the first layer is formed to correspond to the diameter of the residue discharge port 101c.
The third layer plate P3 is not provided with a hole, and constitutes the bottom part of the accommodation hole provided across the first and second layer plates, forming an accommodation hole H having an overall concave shape. .
The second layer plate P2 is arranged so as to be able to slide horizontally between the first layer plate P1 and the third layer plate P3, and as shown in FIG. The mechanism is such that the residue X is discharged into the residue collection container D by sliding it as shown in FIG. 12(b).
Here, the state in which the residue X is accommodated is defined as the accommodation mode, and the state in which the residue X is discharged is defined as the discharge mode, and the sliding of the second layer plate P2 is performed manually or automatically under electrical control. Good too.

(Effect of residue storage and discharge mechanism)
By employing the residue storage and discharge mechanism 21 of this embodiment, the residue can be discharged without changing the internal pressure of the main body 10, as in the first embodiment, so that a swirling flow is generated. Even when solid-liquid separation is being performed, solid-liquid separation can be performed without reducing work efficiency or work accuracy in discharging the residue X.
Furthermore, the amount of the dirty liquid L1 accommodated in the accommodation hole H and discharged together with the residue X can be suppressed, and the residue X can be efficiently discharged.

(Third embodiment)
As shown in FIGS. 13 and 14, the cyclone solid-liquid separator 3 according to the third embodiment of the present invention is designed to maintain a constant internal pressure inside the main body 12 during solid-liquid separation. It is characterized by having a supply port 102d for internal pressure maintaining liquid Lm for supplying a certain amount of liquid to the lower part B of the main body.
By discharging the residue X by the residue storage and discharge mechanisms 20 and 21 shown in the first embodiment and the second embodiment, the residue X is deposited in the first storage part H1 and the lower part B of the main body part 12. It is assumed that a part of the dirty liquid L1 is discharged together with the residue X. At this time, the internal pressure of the main body portion 12 changes slightly, causing unevenness in solid-liquid separation, which may impede highly efficient and stable solid-liquid separation. Therefore, the internal pressure of the main body 12 is kept as constant as possible by the internal pressure maintaining liquid Lm, and solid-liquid separation is performed more efficiently than the cyclone type solid-liquid separators 1 and 2 of the first and second embodiments described above. maintain.

To adjust the supply amount of the internal pressure maintaining liquid Lm, a sensor is provided at a predetermined height in the lower part B of the main body 12, and the volume of the dirty liquid L1 accumulated in the lower part B of the main body 12 is monitored by the sensor. If the predetermined height has not been reached or if it has decreased due to the discharge of the residue supply
The supply port 2d is provided at a position lower than a predetermined height (the level of the accumulated dirty liquid L1) (see Y in FIG. 14). This is to prevent the internal pressure maintaining liquid Lm from being affected by the swirling flow during supply.
It is desirable that the internal pressure maintaining liquid Lm supplied here be connected to the supply port 2d by providing a flow path (circuit) that utilizes a part of the dirty liquid Lc or the clean liquid Lc after solid-liquid separation. .

As mentioned above, the cyclone solid-liquid separator and the residue storage and discharge mechanism in the cyclone solid-liquid separator of the present invention can be adopted in various forms of cyclone solid-liquid separator, and can be used in containers and conveyor devices. This eliminates the need for complicated residue discharge equipment, reducing environmental impact and contributing to space-saving and highly efficient solid-liquid separation.
