[0002]
[Prior art]
In general, when drilling a body to be drilled W such as inner and outer walls of concrete, porcelain tile, stone, etc., a portable rotary drilling tool 100 (hereinafter referred to as an electric drill) is used (see FIG. 5).
In the electric drill 100, the drilled body W is drilled by causing the cutting blade 101 to abut against the drilled body W and rotating, but due to friction between the cutting blade 101 and the drilled body W. In some cases, the cutting blade 101 is heated, a load is applied to the motor that rotates the cutting blade 101, the motor is broken, and fine cutting waste M generated by drilling floats in the surrounding environment.
[0003]
For this reason, a method has been proposed in which when drilling the drilled body W, the drilled body W is drilled while supplying a fluid to the tip of the cutting blade (hereinafter referred to as the cutting edge).
In this method, there are a method using a gas such as a cooling gas and a method using a liquid such as water as the fluid supplied to the blade edge. However, in the method using a gas such as a cooling gas, it is difficult to carry a tool because an auxiliary facility such as a compressor is required to supply the cooling gas. The problem of heat generation can be improved, but the other problems are completely solved. However, it has the disadvantage that it cannot be resolved.
Therefore, a method using a liquid such as water has been dominant as the most effective method for solving the above problems.
[0004]
[Problems to be solved by the invention]
However, the following problems to be improved were also included in the method of punching the drilled object W while supplying the liquid to the cutting edge.

(2) Since the suspension overflows the surface of the drilled body, the surface of the drilled body and its surroundings (for example, the ground) are contaminated.
(3) A problem that a large amount of liquid is used for perforation.
(4) There is a problem that the place where the drilling work is performed is an external wall such as a building, and it is difficult to secure and replenish water.
(5) The problem that a large and heavy device cannot be used when the working space is narrow for drilling.
[0005]
Accordingly, an object of the present invention is to be used in a portable rotary drilling tool for drilling a drilled body by rotating a cutting blade while supplying a liquid to the blade tip, and a liquid containing a suspension, that is, a cutting waste, is placed around it. A portable circulating filtration device that collects the suspension, removes cutting waste in the suspension, and then circulates again to the cutting edge so that the amount of liquid used can be reduced without scattering. It is to provide.
[0006]
[Means for Solving the Problems]
In view of such circumstances, the present inventor has intensively studied and, as a result, has achieved the above-described problem by adopting the following apparatus configuration. That is, it is a portable circulation filtration device used for a rotary drilling tool that rotates a cutting blade while supplying a liquid to the blade edge to punch the drilled body, and the cutting waste of the drilled body is added to the liquid supplied to the blade edge.

And a suspension discharge hole provided in the drain pipe (claim 1).
[0007]
According to such a configuration, the liquid supplied to the blade edge is recovered as a suspension containing the cutting waste of the drilled body, and after the cutting waste contained in the recovered suspension is removed to form a separated liquid, It is supplied to the cutting edge again through the storage means. Therefore, since the liquid supplied to the cutting edge is circulated and reused, a large amount of liquid is not required for drilling the body to be drilled unlike the conventional apparatus . Also, in use of the portable rotary drilling tool, storage means, separating means, the circulating means is because it is housed in a portable unit, it can be easily carried. Therefore, the movement of the worker is facilitated, and the work efficiency is improved.
[0008]
In addition, the suspension is always supplied to a predetermined storage unit (first storage unit), and the suspension that cannot be filtered by the first storage unit is provided adjacent to the first storage unit. It is supplied to the second container and filtered. Therefore, if the suspension cannot be filtered due to clogging or the like in the first storage part, the suspension is stored in the adjacent second storage part and filtered. And when it becomes impossible to filter in the second housing part, the filtration is performed while sequentially replacing the housing parts as in the third, etc., so that the life of the separating means is longer than when only one housing part is provided. Can be measured.
[0010]
In addition, the housing part forming the filtration part is folded so as to form a plurality of ridges (Claim 3).

[0017]
In the electric drill 2, the water supplied to the introduction portion 14 is guided into the hole 12 through the introduction hole 16 provided on the outer peripheral surface of the rotating shaft 13. Next, the bit 12 is supplied through the hole 12. Then, the water supplied to the bit 11 passes through the gap between the contact surfaces of the drilled body W and the bit 11 and overflows on the surface of the drilled body W as a suspension together with the cutting waste of the drilled body W. .
[0018]
The suspension collection means 3 of the portable circulation filtration device 1 of the present invention includes a sponge packing 18 and a suspension collection unit 19.

The suspension recovery part 19 of the suspension recovery means 3 guides the suspension guided by the sponge packing 18 to the discharge port 36 provided in the lower part thereof (see FIG. 2).
[0019]
The separation means 4 of the portable circulating filtration device 1 of the present invention is a filter 20 that separates cutting waste from water containing a cutting waste generated when a hole is made in the drilled body W, that is, a suspension. (See FIGS. 3 and 4).
Here, when a specific example is given as cutting waste, it is concrete powder when the drilled body is concrete.
[0020]
This filter 20 is accommodated in the storage means 5, a connection port 21 for introducing the suspension into the filter 20, and the cutting waste contained in the suspension by storing the suspension. And a bag-shaped filtration part 24 having a second accommodation part 23, and a guide for always guiding the suspension supplied to the filter 20 to the first accommodation part 22. A portion 25 is provided.
[0021]
This filter 20 is composed of a nonwoven fabric, and any nonwoven fabric may be used as long as it is a nonwoven fabric capable of filtering off cutting scraps having a size of 2 μm or more contained in the suspension. However, the filtering material described in the applicant's patent application (Japanese Patent Application No. 2000-215421) is preferable from the viewpoint of filtration processing efficiency and the like.
[0022]
A magic tape 26 (attachment means) for attaching the drain pipe 35 of the circulation means 6 to the filter 20 is provided at the connection port 21 of the filter 20.
Therefore, when the drain pipe 35 is inserted into the filter 20 from the connection port 21, the drain pipe 35 can be easily attached to the filter 20 by winding the magic tape 26 along the outer peripheral portion of the drain pipe 35.
The attachment means is not particularly limited as long as the drain pipe 35 can be attached to the filter 20, and may be, for example, a string. Further, the size of the diameter of the connection port 21 can be appropriately selected according to the diameter of the drainage pipe 35 to be inserted.
[0023]
A plurality of suspension discharge holes 27 are provided on the outer peripheral surface of the drain pipe 35 inserted through the connection port 21 to constitute the guide portion 25. The position at which the suspension discharge hole 27 is disposed is not particularly limited as long as the suspension supplied to the filter 20 is always supplied to a predetermined storage portion. In the present embodiment, the position is directly above the first accommodating portion 22 so that the suspension is always supplied to the first accommodating portion 22. It should be noted that the number of suspension discharge holes 27 and the size of the suspension are determined so that the suspension supplied through the drain pipe 35 stays in the drain pipe 35 and the suspension is supplied to the separation means 4. The introduction is not particularly limited as long as the introduction is not inhibited.
[0024]
The filter unit 24 of the filter 20 includes a first storage unit 22 and a second storage unit 23 provided adjacent to the first storage unit 22.
The suspension supplied to the filter 20 is always guided to the first accommodating portion 22 due to the presence of the suspension discharge hole 27 provided in the drain pipe 35. Therefore, when the filtration efficiency of the first storage unit 22 decreases with the progress of filtration, the suspension that cannot be processed is supplied to the second storage unit 23 adjacent to the first storage unit 22, Filtered.
[0025]
Here, the cutting waste in the suspension supplied to the filter 20 is heavy, such as concrete or metal powder. Therefore, since the cutting waste having a high specific gravity is once removed by the first storage portion 22, the suspension supplied to the second storage portion 23 does not contain much cutting waste that is a main cause of clogging. .
Therefore, compared to the configuration with only one storage section, the life of the filter can be extended, the filtration speed does not decrease in proportion to the throughput of the suspension, and the piping due to pressure increase in the piping caused by clogging Various effects can be obtained, such as preventing the bursting of the pump and the breakage of the pump.
In addition, in the filter which provided two accommodating parts, compared with the filter which provided only one accommodating part, compared with the total use time, the filter lifetime more than twice was confirmed.
[0026]
For the reasons described above, it is preferable that the number of storage units included in the filtering unit 24 be at least two. However, when the number of storage units is increased, the capacity of each storage unit decreases accordingly, and conversely, the filtration processing efficiency of the filter 20 decreases. Therefore, although the number of accommodating parts depends on the size of the storage means 5 that accommodates the filter 20 as the separating means 4, it is preferably about 2 to 4.
Here, in the case of the portable circulation filtration device 1 of the present invention, about 30 to 40 seconds is assumed as the time required for one perforation. At this time, the amount of water discharged from the cutting edge is approximately 200 to 250 ml. Therefore, the capacity of the accommodating portion can be appropriately determined based on the weight and space of the portable filtration device 1 of the present invention in addition to the amount of water used.
[0027]
Further, as shown in FIG. 4, the filter 20 is folded so that a contact area with the suspension supplied in the filter 20 is increased, and a plurality of ridges are formed inward of the housing portion. Has been. FIG. 4 is a diagram showing a state in which the lower portion of the filter 20 is expanded so that the folded state of the filter 20 can be easily understood.
The folding method of the filter 20 is not limited to this folding method as long as it is a folding method in which a plurality of ridges are formed toward the inside of the housing portion, and can be appropriately determined as desired.
[0028]
This filter 20 is accommodated in the storage means 5 in a folded state, and the cutting waste from the suspension is filtered in the folded state at the beginning of drilling of the drilled body W. As the filtration progresses and the amount of the suspension contained in the accommodation portion increases due to a decrease in the filtration efficiency, the suspension is gradually unfolded due to the weight of the suspension, and the capacity of the accommodation portion increases. It is configured as follows.
Further, since the storage means 5 in which the filter 20 is accommodated is configured to be hermetically sealed, when the pump 31 of the circulation means 6 is operated, the storage means 5 is generated by suction of water stored in the storage means 5. By the forced supply of water to the separation means 4 by the negative pressure and the discharge force of the pump 31, filtration of the suspension with the filter 20 is promoted.
[0029]
The storage means 5 of the portable circulating filtration device 1 of the present invention is a container for storing water to be supplied to the bit 11 of the electric drill 2.
[0030]

[0031]
By providing such storage means 5, the portable rotary drilling tool 1 of the present invention can always store the water supplied to the bit 11 during drilling. Therefore, even if the place where the drilling operation is performed is a position away from the water supply location such as water supply, the drilling operation can be performed without any problem.
[0032]
The circulation means 6 of the portable circulation filtration device 1 of the present invention supplies the water stored in the storage means 5 to the bit 11 of the electric drill 2 for discharge. Next, simultaneously with the discharge, the water that has become a suspension containing the cutting waste of the drilled body is collected and circulated to the storage means 5 again through the separation means 4 described later.
[0033]
The circulation means 6 includes a pump 31, a water absorption pipe 32, a water guide pipe 33, and a drain pipe 35.
The pump 31 of the circulation means 6 is configured to operate in conjunction with the rotation of the motor of the electric drill 2. The pump 31 is a pump capable of sucking the water stored in the storage means 5 through the water absorption pipe 32 and stably sending it out to the water guide pipe 33, and is particularly small and lightweight. It is not limited. For example, a gear pump that can stably send water without causing pulsation, a tube pump that does not require priming water, and is easy to maintain can be used.
In the present embodiment, the pump 31 is provided at the upper part of the storage unit 5 so that the capacity of the water stored in the storage unit 5 is maximized, but the water can be circulated stably. The position is not particularly limited as long as it is a position where the amount of water stored in the storage means 5 can be maximized, and can be appropriately selected.
[0034]
One end of the water absorption pipe 32 of the circulation means 6 is connected to the suction port (not shown) of the pump 31, and the other end is immersed in water stored in the storage means 5. The position where the water absorption pipe 32 is immersed is preferably provided so as to extend over the bottom surface of the tank constituting the storage means 5 so that water can be sucked effectively.
One end of the water conduit 33 of the circulation means 6 is connected to the discharge port (not shown) of the pump 31, and the other end is connected to the introduction port 17 provided in the introduction part 14 of the electric drill 2.
One end of the drain pipe 35 of the circulation means 6 is connected to the discharge port 36 of the suspension recovery unit 19, and the other end is inserted into the connection port 21 of the separation means 4 described later.
[0035]
In addition, since the water which penetrates the said water absorption pipe 32, the water conduit 33, and the drain pipe 35 is the water which passed through the bit 11 which generate | occur | produced by friction, it may take heat from the bit 11 and may become high temperature. Therefore, the material constituting the water absorption pipe 23, the water guide pipe 33, and the drain pipe 35 is preferably a material that has heat resistance, is light in weight, is flexible, and is not easily bent. Therefore, in this embodiment, a Teflon blade hose is used.
[0036]
Therefore, when the pump 31 of the circulation means 3 is operated, the pump 31 pumps the water stored in the storage means 5 through the water absorption pipe 32 and supplies it to the introduction part 14 of the electric drill 2 through the water conduit 33. . Subsequently, the water supplied to the introduction unit 14 is guided to the bit 11 and discharged, and includes a cutting waste of the drilled body to become a suspension, and the drain pipe 35, It circulates to the storage means 5 through the separation means 4.
[0037]
With this configuration, the water supplied to the contact surface between the bit 11 and the drilled body W does not overflow as it is as in the conventional electric drill (see FIG. 5). It becomes possible to solve problems such as splashing of suspension and consumption of a large amount of water.
[0038]
The portable means 7 of the portable circulatory filtration device 1 of the present invention is a collection of the separation means 4, the storage means 5 and the circulation means 6 necessary for circulating and reusing the water supplied to the bit 11. Therefore, portability is improved.
In the present embodiment, the storage means 5 has a configuration in which the pumps of the separation means 4 and the circulation means 6 are integrally formed. In this case, the portable means 7 is a handle 40.
The portable means 7 is not limited to this configuration. For example, the portable means 7 may have a configuration in which the separation means 4, the storage means 5, the pump 31, and the like are separately accommodated in a basket or the like. is there.
Further, the portable means 7 is not limited to the configuration held in the hand, and can be appropriately selected from a shoulder-mounted type, a configuration suspended on the waist by a belt, and a configuration supported on the back by a backpack.
[0039]
In this way, the portable means 7 is provided, and the separating means 4, the storage means 5 and the circulation means 6 are accommodated therein, so that the rotary perforation tool (electrically operated) provided with the portable circulation filtration device 1 of the present invention is provided up to the work place. The drill 2) can be easily transported.
[0040]
Therefore, in the electric drill 2 equipped with the portable circulation filtering device 1 of the present invention, the water supplied to the blade edge is circulated and reused, so that it is compared with a conventional portable rotary drilling tool that simply supplies water. The amount of water used can be reduced. Since the water to be supplied to the contact surface between the cutting edge and the drilled body is stored in advance, the work can be performed without any problem even if the work place is separated from the water supply place. Moreover, since there are few parts attached to a tool and it is integrally formed so that main components can be carried, there is no restriction on the place where drilling work is performed, and the weight is light. Since the filter has a special shape, it has the characteristics of good filtration efficiency and long filter life.
