Description

filter case

The present invention relates to a filter case used in a purifier and the like, and more particularly, to a filter case having an efficient configuration for management such as replacement of an internal filter.

Various raw materials or sub-materials and chemicals such as processing chemicals are required for process progress in facilities such as semiconductor plants or display plants. When supplying these substances to the process, in order to prevent product defects and process defects due to impurities, liquid raw materials and process chemicals are usually purified through a filter and supplied in many cases.

Even when the treated material is recycled in the process, in most cases, a filter with a filter is installed in a part of the cycle to remove the contaminants introduced in the process, and the treated material is put into the process in a filtered state. will do

Similarly, in order to keep the process environment clean, there are many cases in which the internal pressure is adjusted to create an air flow, and the internal air is filtered and then supplied again.

In so many cases, the use of a filter is essential, but as the process progresses, the filter becomes contaminated with impurities mixed in the material flowing through the filter. It is reused after a regeneration process that removes contaminants from the filter.

However, in the process of carrying out the process while the material is flowing, the filter is generally used continuously in one part of the pipe that supplies the material, so it is necessary to stop the supply of the material for replacement or regeneration of the filter, and the process itself is usually interrupted.

Improving the utilization efficiency of process equipment in the production process is urgently requested to reduce production costs, and it is important to minimize the downtime even when the process is stopped for filter replacement or regeneration.

Therefore, it is necessary to open the case in the purifier or filter to remove the filter installed therein, and to reduce the time to install the filter in a normal state. It is possible to reduce the time it takes to check or replace the filter condition inside the case by simplifying the combination of the filter and the filter.

1 and 2 are a perspective view and a side cross-sectional view showing an example of a configuration of a conventional filter case. Looking at this conventional filter case configuration, a part of the case has an inlet part 30 through which a substance is introduced, and the other part has an outlet part 20 through which a substance is discharged, and an inlet part 30 and an outlet part 20 are provided. A filter is installed in the inner space of the case, so that the material from the inlet must pass through the filter and go out to the outlet.

An opening, such as a door or window, may be installed in a part of the case to install or remove the filter within the case. Such an opening may be completely spaced apart from the remaining portion of the case, or may be made to open the opening while a part thereof is coupled to the remaining portion by a hinge or the like.

Here, the open part and the residual part may be made of two substantially identical parts as a relative concept.

For example, as shown in FIGS. 1 and 2, both the open part 11 and the remaining part 13 are made of a semi-cylindrical container, and flanges 111 and 131 are formed around the open part of the semi-cylindrical container, Bolt holes are formed in the flanges 111 and 131, and when the open portion 11 and the remaining portion 13 are combined, the flange 111 of the open portion and the flange 131 of the remaining portion are matched with the bolt holes. A method of fastening the bolt 15 and the nut 17 may be used.

However, in order to proceed with the process after the opening, the opening must be well coupled and closely adhered to the rest of the case, so that the problem of material leaking from the purifier to the outside does not occur.

A gasket or packing is placed at the place where the open part 11 and the residual part 13 come into contact for the close contact and bonding of the open part 11, and the material leaks into the gap between the open part 11 and the residual part 13. To prevent this from happening, a coupling means and a locking device are used to mutually fix the open part and the remaining part.

In addition, in a purifier that is installed in a pipe that supplies substances at high pressure or needs to maintain a high degree of purification, the possibility of material leakage due to such a gap is high. Avoid material leakage due to

As shown in FIG. 2 , conventionally, coupling means such as bolts 15 and nuts 17 are often used as conventional coupling means. However, in this configuration, to replace the filter or check the inside of the purifier, it is necessary to loosen the bolt-nut coupling installed in many places fixing the opening to the remainder. If bolts and nuts are installed in multiple places to prevent leakage, the bolts must be loosened in proportion to the number and then re-tightened, which takes a lot of time, effort and trouble.

In addition, even when the filter is installed inside the case, in order to prevent the material to be supplied from leaking from the inside to the outside of the filter, it is often the case that the filter frame is fixed inside the filter case with a screw 43 or the like through a packing or the like.

Of course, if you use a power tool to tighten and loosen the bolt nut, you can reduce the effort and processing time, but it still takes a lot of time, and in the process, problems such as loss of the bolt nut and loosening of the bolt due to vibration during use may occur.

Republic of Korea Registered Utility Model No. 20-0478479

The present invention is to solve the problem that it takes a lot of time, effort and trouble when opening and closing the opening for filter replacement or status check in the conventional filter case described above, and opens and closes through a coupling means of a simple configuration An object of the present invention is to provide a filter case that can reduce the hassle of

The present invention provides a filter case that is installed in the open part and the rest of its surroundings so that it can be opened with a simple operation without being easily separated or lost, and can be closed by reliably and stably combining the opening with the remaining part. intended to provide

The present invention for achieving the above object,

In the filter case having a case body in the form of a container as a whole so that a filter can be installed in the inner space, and an outlet and an inlet part installed in the case body part and connected to a part of a pipe, the case body part is mutually detachable or connected It is characterized in that it has an open part and a residual part that can be separated from the lung, and a toggle clamp of a cicada ring type as a coupling device for fixing the open part and the residual part to be detachably or openable.

The toggle clamp of the cicada ring type of the present invention includes a clasp installed in the open part or the remaining part; with hooks on the clasp; It is installed in the remaining part or the opening, one side is rotatably fixed to the ring and the other side is rotatably fixed to the rotating shaft fixed to the remaining part or the opening part, and having a toggle lever partly made of an eccentric; When closing (mutual binding), hang the ring on the clasp and move the toggle lever coupled to the ring to put the eccentric part in a stable fixed position. It may be made so that the ring can be spaced apart from the clasp.

In the present invention, in a state in which the filter is mounted in the inner space of the case body part, a separate elastic force is applied so that the filter is in close contact with at least one of the leak prevention member on the outlet side and the leak prevention member on the inlet side in the case body part. A pressing member may be provided.

At this time, in the case body part, the open part may be formed in a portion where the pressure by a separate elastic pressing member does not apply, and on the contrary, the open part is formed in the part where the pressure by the elastic pressing member is applied, and the opening part is used as a toggle clamp of a cicada ring type. When binding the remaining part, you can apply a force against the restoring force to bring the open part and the remaining part into close contact, and then bind it with a cicada ring type toggle clamp.

On the other hand, in the present invention, in a state in which the filter is mounted in the inner space of the case body, at least one of the filter is in close contact with at least one of the leak preventing member on the outlet side and the leak preventing member on the inlet side in the case body part. The leak prevention member is formed of an elastic body, and the opening part of the case body is formed in the portion where the pressure is applied by the leak prevention member. It is also possible to bind the open part and the remaining part in close contact with the opposing force with a toggle clamp of the cicada ring type.

In the present invention, the open part and the residual part may be made of two identical parts as a relative concept. For example, both the opening and the remainder are made of a semi-cylindrical container, and a clasp of a cicada ring type coggle clamp is installed around the entrance of one side of these semi-cylindrical containers, and a ring and one side are attached around the entrance of the other half-cylindrical container. The other side of the ring is rotatably fixed to the rotating shaft for fixing with the semi-cylindrical container, and a toggle lever composed of an eccentric part such as an eccentric cam or an eccentric latch is installed. It is also possible to form the entire filter case so that the eccentric part is placed in a stable fixed position by moving the toggle lever, and when opened, the toggle lever is moved in the opposite direction to loosen the hook and the latch coupling to use an opening/closing method that separates the ring from the latch.

According to the present invention, it is possible to reduce the time required to open and close the opening in the filter case, and to reduce the effort and hassle of the opening and closing operation.

In addition, according to the present invention, since the toggle switch of the cicada ring type, which is a coupling means, is fixedly installed on the case itself, it is not easily separated or lost from the case during opening and closing operations, and the opening part can be opened with a simple operation due to the unique eccentric bistableness. It can be opened, and it can be reliably and reliably closed by joining the opening to the remainder.

According to one aspect of the present invention, it is easy to adhere the inlet side and the outlet side of the filter to the inlet side leakage preventing member and the outlet side leakage preventing member within the main body in a state where the filter is mounted in the inner space of the case body unit. When installing the filter itself in the case, it is possible to reduce the hassle and increase the stability.

3 to 5 are a perspective view, a side view and a side cross-sectional view showing an embodiment of the present invention;
6 is a conceptual side cross-sectional view showing the internal configuration of another embodiment of the present invention.
7 and 8 are conceptual side cross-sectional views each showing the internal configuration of another embodiment of the present invention.

According to Figures 3 and 4, the filter case as a whole forms a rectangular parallelepiped container, one of the two surfaces (211, 212) perpendicular to the longitudinal direction of the container (211) and the four sides (213, 215, 217) An outlet portion 120 and an inlet portion 130 on one side 215 extend vertically outwardly from their surface in the form of a kind of pipe.

One side 217, that is, the opening, adjacent to the side 215 on which the inlet 130 is formed, is detachably coupled to the remaining part, that is, the remaining part of the filter case. 260) is used. That is, the clasp of the cicada ring type coggle clamp 260 is installed on the periphery of the edge in contact with the adjacent side from this side (open part), and the rest of the parts except for the latch of the cicada ring type coggle clamp, a ring, a fixing pin or a rotating shaft, A coggle lever with an eccentric is installed around the edge of the proximal side. In order to achieve the binding state, the hook is hooked on each clasp, and the coggle lever is moved to rotate it around the axis of rotation so that the stable point of the eccentric is in contact with the adjacent side beyond the unstable apex of the eccentric.

Since the shape and action of the cicada ring type coggle clamp 260 is well known, a detailed description thereof will be omitted.

The inlet part 130 and the outlet part 120 in the form of a pipe may be installed to be connected to a supply pipe through a pipe connection in a portion of a pipe for supplying a material to be supplied (not shown).

5 shows a state in which the filter 140 is installed in the filter case. In this embodiment, the inside of the filter case is largely divided into two parts based on the filter mounting moving surface 212'. One part is a space for mounting the filter in which the filter 140 is mounted, and the other part is a waiting space where the supply object stays until it enters the filter after it flows into the case.

The inlet of the filter case, which appears when the opening, which is one side 217, is spaced apart from the remainder of the filter case, exposes the filter mounting space and the waiting space inside the case to the outside. The waiting space is a space surrounded by "the other side" 212 among two surfaces perpendicular to the longitudinal direction, a moving surface 212' for filter mounting, and a bellows barrel 219 connecting these two surfaces.

However, the inlet 130 is connected to a part of the bellows barrel 219 in order to allow the supply object to be introduced into the waiting space from the outside, and the filter mounting moving surface 212' has an open hole, and in this open hole It is connected to the inlet side 145 of the filter through a leakage preventing member such as a gasket or packing. A compression coil spring 240 is installed inside the bellows barrel 219 between the filter mounting moving surface 212 ′ and the “other side” 212 . Inside the compression coil spring 240, one end is fixed to the filter mounting moving surface or "the other side", and a guide shaft 212" having a length smaller than the length of the compression spring in a non-pressure state is installed. The length of the 212 ″ may be adjusted by the adjusting screw 250 . Accordingly, when the filter mounting moving surface 212' is pushed toward the "other side" 212, the compression coil spring 240 may be compressed until the length of the guide shaft 212" is reduced.

The filter mounting space is on the "one side" 211 side of the two sides (211, 212) perpendicular to the longitudinal direction of the filter case, and is an auxiliary having a through hole for allowing the filter mounting space to be connected with the outlet part (120). It is a space surrounded by the flat plate 211 ′, the four sides 213 , 215 , 217 , and the moving surface 212 ′ for mounting the filter.

The entire filter 140 forms a frame while holding the filter body 143 for filtering the object and the filter body, and the hole on the inlet side 145 for the object to enter into the filter, and the outlet side 141 for exiting the filter body. It can be made by providing a filter frame in which a hole is formed. The outlet side 141 of the filter frame is brought into contact with the auxiliary plate 211 ′ on the outlet side of the case through a leakage preventing member such as a gasket or packing.

Therefore, in the state shown in FIG. 5, the material flowing into the case from the supply material pipe through the case inlet 130 enters the air space through a part of the bellows barrel 219, and the filter mounting moving surface 212' The case through the opening hole, the inlet side 145 hole of the filter, the filter body 143, the filter outlet side 141 hole, the outlet side auxiliary plate 211' of the case through hole, and the case outlet 120 It flows out to the outside feed material pipe (not shown), and in the process, the filter filters and removes foreign substances from the feed material flowing through the feed material pipe.

To remove the filter 140 from the case in this case configuration, open all the cicada ring type toggle clamps 260 to separate the opening part of the case from the remaining part to open the case, and remove the filter mounting moving surface 212'. After freeing the filter 140 by pushing it toward the other side "212, pull the filter 140 out through the open inlet and remove it.

Conversely, when the filter 140 is mounted on the case, the filter mounting moving surface 212' is pushed toward the "other side" 212 in an open state to secure a large space for the filter mounting in the case, and A state in which the inlet 145 hole communicates with the opening hole of the moving surface 212' for filter mounting and the outlet 141 hole of the filter communicates with the through hole of the outlet side auxiliary plate 211' of the case. Insert the filter into the secured space as much as possible, close the opening 217 of the case to the remaining portion, and then lock the cicada ring type toggle clamp 260 to stably fix it to the remaining portion.

At this time, the force that pushed the filter mounting moving surface 212 ' to the other side 212 of the case is lost, so the compression spring 240 is moved to the filter mounting moving surface 212' by the restoring force to the inlet side of the filter ( 145) and the gasket or packing (leak prevention member) maintain a close contact state, and the outlet side 141 of the filter and the auxiliary plate 211' at the outlet side of the case also maintain a close contact state through the gasket or packing. Thus, leakage of the feed object outside the filter in these parts is prevented.

Therefore, as in the prior art, binding means such as a bolter nut for fixing the filter to a predetermined position in the case without leakage of the target material is not used, and the operation for replacing the filter becomes that simple and convenient.

When removing the filter, the protrusion on the side wall of the case and the corresponding groove part of the filter serve as a kind of guide means to help the replacement conveniently. Alignment between the two can also serve to prevent leakage of feed material at these connections.

6 is a side cross-sectional view showing the internal configuration of another embodiment of the present invention.

In the embodiment of Figure 6, one side (one side perpendicular to the longitudinal direction: 311) on which the outlet part is formed in the case may become an open part and may be spaced apart from the four side surfaces constituting the remaining part, and through this, the inside of the case is opened to save the internal space It is possible to check or replace the filter 140 . Other configurations may be substantially the same as those of the previous embodiment.

Therefore, here, the clasp of the cicada ring type coggle clamp 360 is installed on the periphery of one side, that is, the corner forming the open part, and the ring, fixing pin or rotation shaft, and the eccentric part, which are the rest of the parts except the latch of the cicada ring type coggle clamp, are The excitation coggle lever is installed on the periphery of the corner formed with the "one side" of the four sides. In order to achieve the binding state, the hook is hooked on each clasp, and the coggle lever is moved to rotate it around the axis of rotation so that the stable point of the eccentric is in contact with the adjacent side beyond the unstable apex of the eccentric.

To replace the filter from the case in this case configuration, open the cicada ring type toggle clamp 360 to separate the opening of the case from the remaining part to open the case, remove the existing filter by pulling it through the open inlet, Mount the filter by simply sliding it into the filter mounting space. At this time, the moving surface for mounting the filter is naturally pushed toward the "other side" to secure a space for mounting the filter.

In this embodiment, the protrusion part installed on the side wall of the case and the groove part of the filter corresponding thereto in the same form as in the previous embodiment may be obstructed in this embodiment, so it is removed or installed in the longitudinal direction through which the filter enters and exits. Here too, alignment between the open hole and the filter inlet hole, the filter outlet hole and the case outlet is automatically made, which can serve to prevent leakage of feed material from these connections.

After installing the filter in the case, open the case with the inlet hole of the filter communicating with the opening hole of the moving surface for filter mounting and the outlet hole of the filter communicating with the outlet of the case with the case open. After attaching the part to the rest in the longitudinal direction, lock the cicada ring type toggle clamp to stably fix it to the rest.

Here too, when the toggle clamp is locked, the operator's force to push the filter mounting surface to the other side of the case is lost. The close contact is maintained through the medium, and the outlet side of the filter and the outlet side of the case are also maintained in close contact through the gasket or packing, so that leakage of the object to be supplied to the outside of the filter is prevented in these parts.

On the other hand, in order to prevent leakage of the fluid of the object, the leak prevention member installed at the portion where the filter and the case are in contact with each other is often made of an elastic material such as rubber, and these themselves are made of a single elastic body. Therefore, in the embodiment shown in Fig. 6, there is no need for an elastic body such as a separate compression spring to exist. It may be a space of a fixed volume rather than a space whose volume is variable.

In this case, after the filter is installed in the case, in the state in which the case is open, align the inlet hole of the filter with the opening hole of the filter mounting moving surface and the filter outlet hole through the outlet of the case. By pushing the open part of the case into close contact with the remaining part in the longitudinal direction, at the same time compressing the elastic leakage preventing member, locking the cicada ring type toggle clamp and stably fixing it to the remaining part.

Then, by the elastic restoring force of the leak prevention member, the filter mounting surface is kept in close contact with the inlet side of the filter through the gasket or packing (leak prevention member), and the outlet of the filter and the outlet of the case are also gasketed. Or, since it maintains a close contact state through the packing, leakage of the object to be supplied to the outside of the filter in these parts is prevented.

7 is a side cross-sectional view showing the internal configuration of another embodiment of the present invention.

In the embodiment of Fig. 7, unlike the embodiment of Fig. 5, the filter mounting moving surface 312 for installing the filter is fixed to the filter case by a spring hinge 314 instead of a compression coil spring. One side of the moving surface 312 for mounting the filter is rotatably fixed by a spring hinge 314 , and the other side is moved by the rotation of the moving surface for mounting the filter.

In this configuration, in order to replace the filter, first open the cicada ring type toggle clamp 260 to expose the filter and the filter mounting space inside the filter case with the opening made of one side separated from the remaining part, and then the filter is mounted Rotate the moving surface for the filter around the rotational axis of the spring hinge to enlarge the free space for the filter to enter and exit from the filter mounting space.

Then, a new filter is inserted, and the force that rotates the moving surface for mounting the filter is removed so that the moving surface for mounting the filter returns to its original position. Even in the original position, the spring hinge 314 is configured so that the restoring force of the spring acts as a filter, so that the filter mounting moving surface is in close contact with the inlet side of the filter, and the opening hole and the filter inlet hole are also aligned.

In this state, the opening part is placed in close contact with the remaining part, and the toggle lever of the cicada ring type toggle clamp is operated to lock the cicada ring type toggle clamp.

Therefore, in this embodiment, in the state where the filter is mounted in the inner space of the case, the spring hinge exerts restoring force so that the filter is in close contact with at least one of the leak preventing member on the outlet side and the leak preventing member on the inlet side in the case body. It acts as an elastic pressing member that acts.

On the other hand, a stopper (316) may be installed inside the case to prevent the filter mounting moving surface from excessively returning to the outlet side by the restoring force of the spring hinge while the filter is out of the case and from entering the filter mounting space. , instead of a stopper, it may be bound and fixed to a kind of fastening device. Of course, in this case, to remove the filter, force is applied to the moving surface for mounting the filter, and when rotating, loosen the fastening value and apply force.

8 is a side cross-sectional view showing the internal configuration of another embodiment of the present invention.

In the embodiment of Fig. 8, it has an overall similar configuration to the embodiment of Fig. 7, and the spring hinge attaches the filter to the structure at the installation position inside the filter case to prevent object leakage, but unlike the embodiment of Fig. 7, the filter The filter mounting moving surface 412 for installation achieves a state in which the filter is installed in the filter mounting space in the absence of a filter. Therefore, when the filter is mounted, a part of the filter comes into contact with a part of the moving surface for mounting the filter and pushes the moving face 412 for mounting the filter out of the filter mounting space. 414), the moving surface for mounting the filter pushes the filter toward the outlet and maintains close contact with the inlet side of the filter.

On the other hand, in this configuration, when the filter is mounted on the case, the inside of the case is a stopper for preventing the spring hinge 414 and the filter mounting moving surface 412 from being excessively displaced toward the inlet and entering the plastic deformation region by a strong force. :416) can be installed, and when a type of fastening device is installed instead of a stopper and the filter is completely mounted in the correct position, the moving end of the moving surface for mounting the filter is bound to this fastening device and fixed. .

On the other hand, in the embodiment of FIGS. 7 and 8, the bellows barrel of the waiting space is not shown, but in order to better prevent leakage in the filter case due to the gap between the filter mounting moving surface and the case body, the configuration is as shown in FIG. A bellows barrel may be installed.

In the above, the present invention has been described through limited embodiments, but the present invention is not limited to these specific embodiments.

Therefore, those of ordinary skill in the art to which the present invention pertains will be able to make various changes or application examples based on the present invention, and it is natural that such modifications or application examples belong to the appended claims.
