JPH0618605B2 - Gaseous fluid separator - Google Patents

Description

The present invention relates to a separator for a gaseous fluid such as a cooling fluid, an oil mist, a thickening mist, and a foreign substance-containing air, and more particularly,
An end region that has an open cross section and has a trough shape and has dividing members arranged in opposite rows, and the end regions of the dividing members are arranged in rows extending downward to influence the flow velocity of the fluid. A separator in which a chamber is formed between the narrow passages of the.

Related separators are disclosed in West German Patent DE-PS 26 41 765 and West German Patent Publication DE-AS 27 18 611. In this separator, a single dividing member, also called a trough, is firmly fixed to the frame. In order to remove the dirt collected between the dividing members, the entire separator, for example,
It is necessary to remove it from the temporary ceiling or to remove it from the casing holding various separation plates for cleaning. Swiss patent CH-PS 550 018 discloses a separator in which the ends of a trough-shaped dividing member overlap and oppose each other without forming a chamber that affects the flow velocity of the fluid therebetween. However, a particular row of split members is retained in a removable frame independent of the rest. This makes cleaning somewhat easy. Nevertheless, when the size of the separator is increased, it becomes difficult to handle, which is not preferable.

The present invention relates to a separator of the above-mentioned type, and therefore, in addition to high separation efficiency, it is easy to clean a single dividing member, and this configuration can reliably manufacture separators having different surface areas. it can.

The object of the present invention is achieved by disposing each dividing member in the separator in a removable manner. Due to its removability, the dividing member can be easily removed and thus can be easily cleaned and replaced, for example. Even a single dividing member can be cut to the desired length,
Can be stored in an existing frame. By removably placing a single dividing member in the separator,
The split member can be rotated about its long axis to allow adjustment of the chamber to affect flow rate. Therefore,
Depending on the specific required area of the separator, the separation efficiency is improved or reduced.

Further, in the present invention, in order to form another chamber, the dividing member has a protrusion at the apex of its inner region, the protrusion extending toward the opening of the dividing member and extending along its long axis. is doing. The cross-section is preferably formed in the shape of a knob, and the presence of a protrusion called an inner protrusion extending from the apex of the inner surface, in the region of the dividing member or at the end of an adjacent dividing member engaging with the dividing member, further the chamber Can
As a result, the flow velocity of the fluid flowing through the separator is continuously influenced, while the separation efficiency is increased.

A holding member is provided for easily fixing the dividing member to the separator, the holding member surrounding at least its outer region the dividing member whose opening partially faces the fluid. The split member, the outer region of which faces the steam to be cleaned, is fixed by the member surrounding the inner projection. Therefore, at least the region of the holding member that holds the split member is configured to have elasticity. The holding member itself is held, for example, by a metal track, which partly covers the front area of the split member. The tracks containing the retaining members are arranged such that they are adjustable in the same direction by a predetermined amount. As a result, the separation region is adjustable relative to the fluid that permeates. This makes it possible to configure the track including the holding member so that the separator has two separation regions including an acute angle whose tilt angle is adjustable.

The retaining member can be made, for example, of rubber, plastic or metal and can be constructed as a strip with the necessary recesses for interacting with the dividing member. However, it should be noted that in the present invention, the holders of the dividing members consist of a single member that can be positioned in a row. The unitary member in each case emerges from the substrate region at an angle to the substrate region and has strips with elastic properties. The strip partially surrounds the dividing member whose opening faces the rising fluid, the ends of the strip bending at opposite angles with respect to each other.
The opposite ends of the two adjacent end pieces hold the inner projections of the dividing member whose outer region faces the rising fluid and fix the dividing member. Through the corresponding embodiments of the retaining member, in order to arrange the split members so that they can be easily detached, the single members are positioned adjacent to each other in a row depending on the number of the split members required for the separator. Only thing is necessary.
The elastic properties of the strips, which are angled away from the substrate surface, ensure both a secure lock and a tool-free release.

Through the proposal of this invention, the separator is arranged so that its single member is not rigidly attached to the frame. On the other hand, the separator has the desired surface area without any problems. For this reason, it suffices that the split member be cut to a desired length and detachably fixed to the holder. This makes it possible to easily and visually clean all the regions of the separator by simply removing the single dividing member. On the other hand, due to the presence of the inner protrusion, the flow velocity of the fluid between the dividing members is positively affected and the separation is performed with high efficiency.
On the other hand, the dividing member exerts a unique strength so that a large-sized separator can be disposed without danger. This also supports the findings according to the present invention.

The advantages and features of the present invention will become more apparent from the following description of preferred embodiments, which is set forth with reference to the claims and drawings.

FIG. 1 is a sectional exploded view showing a first embodiment of a separator.

FIG. 2 is a sectional exploded view showing the second embodiment.

FIG. 3 is a detailed view of the split member and a holding member that holds the split member.

FIG. 4 is a plan view of another dividing member and a holding member.

FIG. 5 is a perspective view of a partially broken separator.

FIG. 6 is a detailed view showing the holding member of the split member.

7 and 8 show another embodiment of the separator.

1 and 2 are cross-sectional views of a separator according to the present invention, which is a trough-shaped open-type dividing member 1
0,12, the end regions 14,16 of which are inclined downwards so that the chamber 18 is formed in a narrow gap in the end region. Furthermore, the split members 10 and 12 have a protrusion 20 protruding from the inner surface thereof and extending in the direction of the major axis thereof. As a result, the chambers 22 and 24 are further formed in the inner regions adjacent to each other or the ends of the adjacent divided members. The dividing members 10 and 12 are arranged so as to overlap with each other and have a function of cleaning a gaseous fluid such as a cooling medium, oil mist, and air containing pollutants, and are incorporated in a so-called separator. The downwardly sloping ends 16, 18 and the projection 20 allow the chambers 18, 22, through which the fluid flows,
24 is formed, and the velocity of the fluid affects the high efficiency of separation.

The knob-like projections 20 form a flow-through chamber that influences the fluid, while at the same time accommodating each segment with unique stability. The elongated dividing member 1 is provided through the protrusion 20.
0, 12 are held by the holding member without the need for another support. This preferred embodiment is derived from FIGS. 1 and 2.

As a result, each of the holding members 25 and 44 has the plate-shaped base member 2
Have six. Strips 28, 30 extend from the base member 26, at least a portion of which strips 28, 30 are curved along the outer surface 36 of the dividing member 12 whose openings face the fluid and are concave portions 32 facing each other. , 34.
Since the strips 28 and 30 are separated from the base member 26 at an angle and have elasticity, the split member 12 is securely held.
The free ends of the strips 28, 30 oppose each other, so that they extend substantially parallel to the substrate 26.
Therefore, the distance from the two continuous holding members 25, 44 to the end pieces 40, 42 facing each other is equal to
It is selected to such an extent that the protrusion 46 extending in the longitudinal direction of the inner surface of the can be grasped. As a result, the protrusion 46 having a predetermined shape with a knob-shaped cross section is provided between the pieces 40 and 42 and the holding member 25,
It has a holding function as 44. When assembling the separator having the dividing members 10 and 12, the holding members 25 and 44 are attached to the holder 47 or 52 in order to ensure the positioning.
It suffices to arrange them in line on the truck 48 of.
Further, the holder 46 has a shank 5 that crosses the track 48.
0, this shank covers the dividing members 10, 12 in their front regions, so that the fluid flowing through the dividing members 10, 12 does not leak to the side. As a result, the split members 10 and 12 are detachably fixed to the members 25 and 44, which are arranged integrally with the holder 47 or 52 in a line. This allows the split members 10, 12 to be easily cleaned and possibly replaced if damaged. Furthermore,
A split member having an opening facing the fluid is movable along its long axis. As a result, the chamber cross-sectional area through which the fluid flows can be made more effective.

Basically, the embodiment of FIG. 1 and FIG.
Or, only the type of 52 is different, and the others are substantially unchanged. Therefore, the same reference numerals are given to the same members. Apart from this, the split members 10, 12 and their holding members 25,
The structure of 44 or each holder 47, 52 allows the separator to be easily adapted to the desired size. This is a holding member 25, which is arranged next to one another in a row.
This is possible by setting the number of 44 to the required number and cutting the dividing members 10 and 12 to the required length.

Holding members 25 and 44 including pieces 28 and 30 which are elastic members
Can be made of, for example, aluminum, stainless steel, elastic steel or plastic. Similar materials can be applied to the split members 10, 12, which can be plastic extruded members or die cast members.

3 and 4 show the dividing member 58 housed in the holding member 56. The dividing member 58 has a substantially arcuate cross section extending along the semicircle. Furthermore, the protrusion 60 is
It is disposed in the apex region of the cross-section member 58 and projects from the inner surface thereof. As described above, the protrusion 60 increases the stability of the split member 58 in the longitudinal direction on the one hand, and separately from this,
Together with the end regions (not shown) of the dividing members which extend into the inner region of the cross-section member 58, they contribute to the formation of another chamber. The fluid to be cleaned flows through this new chamber. The chamber is formed by the ends 62, 6 of the dividing member 58.
Beading 4 makes it more and more effective. The holding member 56 has the structure shown in FIGS. 1 and 2, and accordingly, the holding member 56 has a plate-shaped base member 66, and from this base member 66, there are two elastic strips 68, 70 having elastic characteristics. Extending vertically, the strips 68, 70 being curved along the outer surface of the dividing member 58 in part in their vertically extending regions 72, 74, extending mainly horizontally and having their tapered ends. The shape is selected so as to grab a protrusion of the type indicated by reference numeral 60. In this way, the dividing member is fixed in its outer region facing the fluid.

If the configuration of the retaining member 56 allows the split member 58 to rotate about its major axis, a fixed position can be provided by the flat portion 80 (FIG. 3) or 82 present on its outer surface. . As a result, the split member can be prevented from rotating carelessly. Since the structure of FIG. 4 is not different from that of FIG. 3, the same reference numerals indicate the same members.

FIG. 5 is a schematic perspective view showing a part of the separator 84, and a dividing member (not shown) is connected to two surfaces thereof intersecting each other at an acute angle. In other words, the separator 84 has a separation area that is in V-shape alignment with each other in cross-section, and the fluid to be cleaned flows through this separation area and the separator 8
4 to the atmosphere opening 88 via the inner region 86. A clean fluid is sucked through this atmospheric opening. Since the dividing members used in the separator 84 are the same as those in FIGS. 1 to 4, the shape thereof is clear from those drawings.

Unlike the above-described embodiment, the holding member for holding the split member is formed in the shape of the strip 90 having the notches 92 and 94 alternately. These notches are alternately selected such that when one split member is held by partially gripping its outer surface, the next split member is held by supporting the inner protrusion. It The retaining strip 90 can be made of rubber, plastic or steel springs.
That is, they hold the split member securely and
It has a spring characteristic that it holds gently. The holding strip 90 is itself held on the tracks 96, 98 of the holder 100. For this reason, the holding strip 90 has rail-shaped rims 103 and 104 extending one level higher in the upper edge region thereof. (Of course, the holding strip 90 can be replaced with the holding members 25 and 44.) As is clear from the drawing shown in FIG. 5, the holding member holding the holding strip 90 is, for example, a rod or a cable wire ( 10
2), the inclination angles of the surfaces formed by combining the divided members are tilted in the same direction in an adjustable manner.

The separator 84 of FIG. 5 also has an advantage that the dividing member applied per 1 m can be used as a single dividing member and is cut into a desired size. Moreover, overall separator 84 does not require a rigid frame as is well known in the art. This dividing member is also detachably arranged in the separator 84 and is easy to clean and replace.

Finally, the detailed illustration of the retaining strip shown in FIG. 6 shows that the flat portion 106 is formed at the apex of the cutout 92, in order to accurately fix the split member in place. A split member is inserted into the and reveals that the opening directly faces the fluid. This dividing member is the third
As described in connection with the split members of FIGS. 4 and 5, it has a flat portion corresponding to the outer surface thereof.

7 and 8 show another embodiment, in which the separators 108 and 110 are arranged so as to be inclined with respect to the rising direction of the fluid to be cleaned. Collective area 118, 120
Are arranged in the lower regions 111 and 112 of the combined dividing members 114 and 116. In this case, the divided areas 114 and 116 have an elliptical cross section, and dirt such as precipitated oil collects in the collecting area. Separator 1
In order to clean 08 and 110, it is only necessary to drain the separated liquid, and it is not necessary to clean the dividing members 114 and 116 themselves. This is a great advantage over conventional separators. In the case of either fiber filters or swirl separators, the grease has to enter the casing and be drained from it. However, this is extremely difficult. This is because the enormous condensate and drainage member in the casing become a lump.

In a conventional construction there is a high risk of a fire behind the filter element in the casing. In the present invention, the grease escapes to the outside and can therefore be easily removed.

Another advantage of the present invention is that the dividers can also be arranged side by side to form a separator plate, such as in a conventional frame or hood. However, the detachable construction of the dividing members and, if necessary, the aforementioned properties, for example the adjustment or collection of grease, are still provided here.
