Description

Technical Field

[0001] This invention relates to filter devices, transport vehicles, and coating devices. Background Technology

[0002] In painting plants and other similar facilities, filter devices using disposable filter elements are widely used. Japanese Patent Application Publication No. 2021-133269 (Patent Document 1) discloses a paint mist removal device that facilitates filter replacement. Furthermore, Japanese Patent Application Publication No. 2016-538118 (Patent Document 2) discloses a filter device capable of accommodating multiple filter elements.

[0003] Patent document 1: Japanese Patent Application Publication No. 2021-133269.

[0004] Patent Document 2: Japanese Patent Publication No. 2016-538118.

[0005] In the filter devices described in Patent Documents 1 and 2, the filter element is designed for single use, so an opening is provided for the filter element to enter and exit, and a door is provided for closing the opening during operation of the filter device. Conventionally, the door has been deformed by the filter element pushing it from the inside, resulting in the opening not closing completely. If the opening is not completely closed, problems may occur, including leakage of exhaust gases such as paint mist and a decrease in the airflow of the exhaust system equipped with the filter element. Summary of the Invention

[0006] The present invention was made in view of the above-mentioned problems, and its object is to provide a coating apparatus in which the opening is kept closed by means of a door in a filter device.

[0007] The filter device of the present invention includes a housing and a tray. The housing has an opening for a filter element to enter and exit, a door for closing the opening, and a door for accommodating the filter element. The tray is used to hold the filter element. The filter device is characterized by having a limiting member disposed between the filter element and the door when the tray holding the filter element is accommodated in the housing, thereby limiting the movement of at least one of the filter element and the tray.

[0008] Based on this structure, it is difficult for the filter element to push open the door and create a gap. Therefore, during the operation of the filter device, the opening can be easily kept closed by means of the door.

[0009] Further features and advantages of the invention become clearer from the following illustrative and non-limiting description of embodiments illustrated with reference to the accompanying drawings. Attached Figure Description

[0023] The embodiments of the filter device, transport vehicle, coating apparatus, and filter element installation method of the present invention will be described with reference to the accompanying drawings. Hereinafter, we will describe the application of the filter device of the present invention to a filter device 1 installed under the floor of the coating room 10 in the coating apparatus 100. Figure 1 The example is used to illustrate this.

[0024] [Structure of the coating equipment]

[0025] The coating apparatus 100 of this embodiment includes a coating chamber 10 and a filter device 1. Figure 1 The painting chamber 10 has an upper trough 10a and a lower trough 10b. The upper trough 10a is positioned above the grid floor 12 and is used for painting operations by the painting apparatus 11. The lower trough 10b is positioned below the grid floor 12 and is connected to the filter device 1. A downward airflow is formed within the painting chamber 10, and air containing paint not adhering to the workpiece is guided from the upper trough 10a to the lower trough 10b.

[0026] With the painting booth connection port 43 connected to the lower groove 10b of the painting booth 10 and the exhaust duct connection port 44 connected to the exhaust duct D, the filter device 1 is installed below the painting booth 10.

[0027] [Structure of the filter device]

[0028] The filter device 1 of this embodiment includes a tray 3 for placing the filter element 2 and a housing 4 for accommodating the filter element 2 and the tray 3. Figure 2 The filter element 2 and tray 3 are positioned on the outside of the housing 4. Figure 3 The filter element 2 and tray 3 are housed in the housing 4.

[0029] (Filter element)

[0030] The filter element 2 is a so-called carton filter, having a filter inlet 21, a filter section 22, and a filter outlet 23. When exhaust gas including paint mist is introduced through the filter inlet 21, the paint mist is captured in the filter section 22, and the exhaust gas with reduced paint mist content is discharged from the filter outlet 23. In this embodiment, the filter element 2 is rectangular in top view.

[0031] (tray)

[0032] The tray 3 has a mounting surface 31 that serves as the surface for holding the filter element 2, and wall members 32 extending upward from the edge of the mounting surface 31. In this embodiment, the mounting surface 31 is also rectangular in plan view, corresponding to the filter element 2 being rectangular. The wall members 32 are positioned at positions corresponding to the sides of the rectangle of the mounting surface 31, thus restricting the movement of the filter element 2. The abutment piece 33 and rod 34, described later, are arranged when the tray 3 is housed in the housing 4. Figure 3 The wall component 32a is located on the front side (one side of the opening 41).

[0033] (case)

[0034] The housing 4 has an opening 41, a door 42, a painting room connection port 43, an exhaust duct connection port 44, and a floor roller 45. It has a generally cuboid main body with two connecting components that function as the painting room connection port 43 and the exhaust duct connection port 44, respectively. The opening 41 is shaped and sized to allow the filter element 2, which is placed on the tray 3, to pass through. The door 42 is a double-hinged door, and closing the door 42 closes the opening 41.

[0035] The painting booth connection port 43 is connected to the painting booth 10 and functions as an inlet for receiving exhaust gas, including paint mist, into the housing 4. The exhaust duct connection port 44 is connected to the exhaust duct D and functions as an outlet for discharging exhaust gas with reduced paint mist content from the housing 4. With the filter element 2 housed in the housing 4, the filter inlet 21 and the painting booth connection port 43 are aligned, and the filter outlet 23 and the exhaust duct connection port 44 are aligned.

[0036] A floor roller 45 is provided on the floor surface inside the housing 4. The floor roller 45 is a so-called roller conveyor-like structure that enables the filter element 2 and the tray 3 to move back and forth in the housing 4. By providing the floor roller 45, the horizontal movement of the filter element 2 and the tray 3 when entering and exiting becomes smooth.

[0037] In addition, in the following description, the movement path of the filter element 2 when it enters the housing 4 from the opening 41 is considered. The side with the opening 41 and the door 42 is referred to as "near front", and the side with the exhaust pipe connection port 44 is referred to as "inner".

[0038] The housing 4 is provided with an abutting member 46, which serves as a first limiting member (a limiting member that abuts against the tray 3) to restrict the movement of the tray 3, and a stop member 47, which serves as a second limiting member (a limiting member that abuts against the filter element 2) to restrict the movement of the filter element 2. Furthermore, for each limiting member to function effectively, the filter element 2 and the tray 3 need to be housed in a predetermined position within the housing 4. This predetermined position could be, for example, the position where the filter element 2 and the tray 3 are pushed to the innermost part of the housing 4. Each limiting member is positioned between the filter element 2 and the door 42 when the filter element 2 and the tray 3 are housed in the predetermined position within the housing 4.

[0039] The abutment member 46 is positioned and sized to abut against the abutment piece 33 located at the end of the tray 3 (near the front wall member 32a). Figure 4 , Figure 5 ). Figure 4 The restriction on the contact component 46 is lifted. Figure 5It is in a state restricted by the abutting member 46. The abutting piece 33 is axially supported in such a way that it can rotate approximately 90° about the axis X1 by operating the lever 34. When the tray 3 is inserted into the interior of the housing 4 through the opening 41, the abutting piece 33 is positioned on the upper side relative to the axis of rotation by operating the lever 34. Figure 4 The shown position (avoidance position). In this position, the abutment piece 33 does not abut against the abutment member 46, so the tray 3 can enter the interior of the housing 4 through the opening 41. After the tray 3 has entered, the abutment piece 33 is positioned to the left relative to the axis of rotation by the operating lever 34. Figure 5 In the indicated state, the abutment piece 33 is in a position to abut against the inside of the abutment member 46. In this state, the movement of the tray 3 towards the front is restricted, and consequently, the movement of the filter element 2 placed on the tray 3 is also restricted. In addition, one abutment piece 33 and one rod 34 are provided at each end of the wall member 32a, and one abutment member 46 is provided on each of the left and right sides when viewed from the front of the tray 3.

[0040] The stop component 47 is supported on the top surface of the housing 4 by means of hinge 48, and can rotate about 90° about axis X2. Figure 6 , Figure 7 ). Figure 6 This is the state where the restriction of the stop component 47 is released. Figure 7 It is in a state restricted by the stop member 47. When the filter element 2 enters the interior of the housing 4 from the opening 41, the stop member 47 rotates upward (avoids) and is in a position where... Figure 6 The state shown. In this state, the stop member 47 does not abut against the upper part of the filter element 2, so the filter element 2 can enter the interior of the housing 4 through the opening 41. After the filter element 2 is inserted, when the stop member 47 extends downward from the top surface of the housing 4 ( Figure 7 The filter element 2 is positioned such that its upper part and the stop member 47 can abut against each other, restricting the filter element 2 from moving towards the front. Additionally, a magnet (not shown) is mounted on the stop member 47, which, by means of the magnet's magnetic force, fixes the stop member 47 in a position along the top surface of the housing 4 (avoidance position). Furthermore, the fixing member 49, which fixes the stop member 47, is provided with a pair of cylindrical pins (dropping pins) 49a and a receiving metal part 49b. Furthermore, when the stop member 47 is viewed from the front, one hinge 48 and one fixing member 49 are provided on each of the left and right sides (a pair).

[0041] Thus, in the filter device 1 of this embodiment, the filter element 2 is restricted from moving towards the front by the contact between the filter element 2 and the wall member 32a, the contact between the contact piece 33 and the contact member 46 (the contact between the tray 3 and the contact member 46), and the contact between the filter element 2 and the stop member 47. This multiple preventions prevent the filter element 2 from moving towards the opening 41 inside the housing 4, maintaining the filter element 2 and the door 42 separated. When the filter element 2 collides with the door 42, the door 42, pushed by the filter element 2, deforms and creates a gap between it and the opening 41, causing problems such as leakage of exhaust gas including paint mist and a decrease in airflow within the housing 4. However, in the filter device 1 of this embodiment, the movement of the filter element 2 towards the front is restricted, so the opening 41 is kept closed by the door 42, and these problems do not occur.

[0042] [Transportation vehicle]

[0043] Next, an embodiment of the transport vehicle 5 used for transporting the filter element 2 will be described. The transport vehicle 5 of this embodiment includes a mounting surface component 51 and a trolley 52 (…). Figure 8 , Figure 9 The filter element 2, before or after use, is placed on the tray 3, and then the tray 3 is placed on the transport vehicle 5, thereby making it easy to move the filter element 2 and the tray 3.

[0044] The mounting surface component 51 is a plate-shaped component capable of mounting the filter element 2. More specifically, the mounting surface component 51 can integrally mount the tray 3 and the filter element 2 placed on the tray 3. In addition, a plurality of ball support members 51a (an example of a rotating body) are provided on the top surface of the mounting surface component 51.

[0045] The trolley 52 is configured to support the mounting surface component 51 and is capable of traveling on the floor. Specifically, the trolley 52 has a frame-shaped main body 52a, casters 52b mounted on the feet of the main body 52a, and a brake 52c (an example of a travel limiting component) that can restrict the travel of the trolley 52.

[0046] The mounting surface member 51 is slidably supported on the main body portion 52a. Furthermore, the front and rear sides of the main body portion 52a in the sliding direction are not framed, so that the mounting surface member 51 extends outside the frame of the main body portion 52a when it slides. Therefore, the transport vehicle 5 can be changed to a first state where the mounting surface member 51 is within the frame of the trolley 52. Figure 8 ), a portion of the mounting surface component 51 extends outside the frame of the trolley 52 in the second state ( Figure 9 () has multiple states.

[0047] 51b slot ( Figure 12The engaging groove 51b is provided on the mounting surface component 51. The engaging groove 51b is positioned and sized to accommodate the abutment piece 33. By engaging the abutment piece 33 with the engaging groove 51b, the relative position of the tray 3 and the mounting surface component 51 can be fixed.

[0048] Furthermore, in the second state ( Figure 9 The fitting positions are provided by a cylindrical pin 51c on the mounting surface component 51 and a receiving hole 52d on the trolley 52 (main body 52a). Figure 12 With the mounting surface member 51 in a sliding range at its end, the cylindrical pin 51c and the receiving hole 52d are engaged, thereby maintaining the transport vehicle 5 in the second state. Meanwhile, the transport vehicle 5 is in the first state (…). Figure 8 At the same time, a receiving hole 52e is also provided at the position that can be engaged with the cylindrical pin 51c, so that the transport vehicle 5 can be maintained in the first state.

[0049] In addition, other structural elements of the transport vehicle 5 will be explained together with the method of installing the filter element 2.

[0050] [Method for setting up filter elements]

[0051] Next, an embodiment of the method for setting up the filter element 2 will be described. The method for setting up the filter element 2 in this embodiment includes a step of accommodating the tray 3 on which the filter element 2 is placed in the housing 4 (hereinafter referred to as the first step) and a step of restricting the movement of the filter element 2 and the tray 3 (hereinafter referred to as the second step).

[0052] (First process)

[0053] Figure 10 and Figure 11 This describes the method of installing a new filter element 2 onto the housing 4 using a transport vehicle 5. First, the transport vehicle 5, carrying the filter element 2 and the tray 3, is parked in front of the housing 4, which does not yet contain the filter element 2. At this time, the transport vehicle 5 is in its first state (…). Figure 8 Next, the door 42 is opened, and the stop member 47 is fixed in a position along the top surface of the housing 4 (avoidance position). Figure 6 At this time, in order to make it easy to align the filter element 2 and the tray 3 with the front of the opening 41, it is preferable to provide a mark as an alignment reference on the floor surface in front of the housing 4. In addition, it is also preferable to provide a ramp (not shown) in front of the housing 4 to guide the tray 3 toward the opening 41. If a ramp is provided, the casters 52b on the protruding side of the mounting surface member 51 are supported by the ramp, so it is possible to prevent the transport vehicle 5 from tilting when the mounting surface member 51 is sliding outward toward the trolley 52.

[0054] Next, the mounting surface component 51 is slid to push the filter element 2 and tray 3 into the housing 4. Figure 11 More specifically, the process involves sequentially moving the transport vehicle 5 from its first state (…). Figure 8 ) Change to the second state ( Figure 9 The first pushing operation involves moving the filter element 2, tray 3, and mounting surface component 51 together by sliding the mounting surface component 51. The second pushing operation involves moving the filter element 2 and tray 3 relative to the mounting surface component 51 and pushing them into the housing 4 while the transport vehicle 5 is in its second state. At this time, the brake 52c is activated, preventing the trolley 52 from accidentally moving.

[0055] Furthermore, the main body 52a is frame-shaped, allowing the user P to enter the frame of the main body 52a to perform operations, making it easy to push the filter element 2 and tray 3 into the housing 4. In conventional transport vehicles where the surfaces carrying the filter element and tray do not slip, operators sometimes find it difficult to push the filter element 2 and tray 3, resulting in poor workability. By utilizing the transport vehicle 5 of this embodiment, workability is improved. Moreover, multiple ball bearings 51a are provided on the top surface of the mounting surface member 51, and the tray 3 is supported by the ball bearings 51a, allowing the filter element 2 and tray 3 to move smoothly.

[0056] When the transport vehicle 5 carrying the filter element 2 and the tray 3 moves in to transport them, or when the transport vehicle 5 is placed on an elevator or similar device and moved vertically along the transport path, it is desirable to prevent accidental movement of the filter element 2 and the tray 3. For this purpose, the cylindrical pin 51c and the receiving hole 52e are engaged until the first push-in operation is performed to maintain the transport vehicle 5 in a first state. Furthermore, until the second push-in operation is performed, the engaging groove 51b of the mounting surface member 51 and the abutment piece 33 of the tray 3 are engaged to fix the relative position of the tray 3 and the mounting surface member 51. Therefore, the tray 3 will not fall off during the movement of the transport vehicle 5.

[0057] Based on the functions of the components described above, the operation of pushing the filter element 2 and tray 3 into the housing 4 is as follows. Additionally, as mentioned earlier, the stop member 47 is pre-positioned along the top surface of the housing 4 (avoidance position). Figure 6 First, after lifting the cylindrical pin 51c to disengage it from the receiving hole 52e, the mounting surface component 51 is slid, changing the transport vehicle 5 from the first state to the second state. When the mounting surface component 51 is slid to the end of the sliding range, the cylindrical pin 51c and the receiving hole 52d are engaged, maintaining the transport vehicle 5 in the second state. Next, the operating lever 34 is used to position the abutment piece 33 above the rotation axis (avoidance position). Figure 4After releasing the engagement with the engaging groove 51b, push the filter element 2 and tray 3 into the housing 4. Confirm that the abutment piece 33 is in the clearance position, and further push the filter element 2 and tray 3 in. When the filter element 2 and tray 3 are further pushed in until the abutment piece 33 is located further inward than the abutment member 46, use the operating lever 34 to position the abutment piece 33 in a laterally restricted position relative to the rotation axis. Figure 5 (The contact plate is in the left position).

[0058] As described above, through a two-stage push-in operation, the new filter element 2, transported by the transport vehicle 5, is housed together with the tray 3 in the housing 4.

[0059] (Second process)

[0060] In the second process, the abutting piece 33 and the abutting component 46 abut against each other to restrict the pallet 3 from moving towards the front. Figure 5 Furthermore, the stop member 47 is changed to extend downwards from the clearance position located on the top surface of the housing 4, restricting the filter element 2 from moving towards the front. Figure 7 After that, close door 42 to complete the setup of filter element 2.

[0061] (Remove the filter element)

[0062] In addition, to remove the used filter element 2 from the housing 4, the operations described above for setting the filter element 2 can be performed in reverse order. First, open the door 42 to release the first and second restrictive components from restricting the filter element 2 and the tray 3 (the second step is performed in reverse order).

[0063] Next, the filter element 2 and tray 3 are pulled out from the housing 4 and mounted on the mounting surface member 51 (the reverse order of the second-stage push-in operation). At this point, it is easier to work with the filter element 2 and tray 3 pulled out from the housing 4 using a rod-shaped member with a hook at the end. Furthermore, if the cylindrical pin 51c and the receiving hole 52d are engaged to put the transport vehicle 5 in the second state, the mounting surface member 51 can be prevented from moving forward when the filter element 2 and tray 3 are pulled forward, thus further improving workability. After the filter element 2 and tray 3 are placed on the mounting surface member 51, the abutment piece 33 and the engaging groove 51b are engaged.

[0064] Then, by lifting the cylindrical pin 51c to disengage it from the receiving hole 52d, the mounting surface member 51 slides, causing the filter element 2, tray 3, and mounting surface member 51 to move as a whole, bringing the transport vehicle 5 to its first state (the reverse order of the first stage push-in operation). Through this sequence, the used filter element 2 can be mounted on the transport vehicle 5. Alternatively, the transport vehicle 5 can be kept in its first state by engaging the cylindrical pin 51c with the receiving hole 52e before the transport vehicle 5 moves.

[0065] [Other Implementation Methods]

[0066] Finally, other embodiments of the present invention will be described. Furthermore, the structures disclosed in the following embodiments can be combined with structures disclosed in other embodiments, provided there are no contradictions.

[0067] In the above embodiments, the structure of the filter element 2 being a cardboard filter was described as an example. However, the shape, material, etc. of the filter element in the filter device of the present invention are arbitrary.

[0068] In the above embodiment, the structure of a double-leaf hinged door provided in the housing 4 is described as an example. However, the type of door in the filter device of the present invention is not limited. Therefore, in the case of a hinged door, the door can be a single door; in addition to hinged doors, sliding doors, folding doors, louvered doors, louvered windows, etc., can also be used.

[0069] In the above embodiments, an example was described with a structure in which a painting room connection port 43 is provided on the upper part of the housing 4 and an exhaust duct connection port 44 is provided opposite the door 42. However, the configuration of the filter inlet 21 and the filter outlet 23 in the filter device of the present invention is arbitrary.

[0070] In the above embodiments, an example was described using a structure in which an abutting member 46, which serves as a limiting member for restricting the movement of the tray 3, and a stop member 47, which serves as a limiting member for restricting the movement of the filter element 2, are respectively provided. However, in the filter device of the present invention, it is sufficient to provide a limiting member capable of restricting the movement of at least one of the filter element and the tray within the housing; it is not necessary to restrict the movement of both the filter element and the tray. However, if the movement of both can be restricted, it is advantageous in terms of maintaining the opening 41 in a closed state by means of the door 42.

[0071] In the above embodiments, an example was described using a structure with an abutting member 46 that can abut against the tray 3. However, in the filter device of the present invention, when a limiting member that can abut against the tray is provided, the abutting method is arbitrary. For example, fitting protrusions and fitting recesses that can fit together can be provided on the housing and the tray respectively, so that when the tray is positioned in a predetermined position, the fitting is completed and the movement of the tray is restricted.

[0072] In the above embodiments, the structure in which the stop member 47 is supported on the top surface of the housing 4 has been described as an example. However, in the filter device of the present invention, if a limiting member capable of abutting against the filter element is provided, this configuration is arbitrary. For example, it may also be provided on the side of the housing.

[0073] In the above embodiments, the structure in which the wall member 32 is disposed at a position corresponding to each side of the rectangle on the mounting surface 31 has been described as an example. However, in the filter device of the present invention, when the wall member is disposed on a tray, its configuration is not limited. For example, Figure 13 In the modified tray 3A shown, wall members 32 are provided on the three sides of the mounting surface 31, which correspond to the shape of a rectangle. In this modified example, when the filter element 2 is placed on the tray 3A, it is possible to place the filter element 2 on the tray 3A without raising it higher than the wall members 32, as long as the filter element 2 passes through the portion without the wall members 32. Alternatively, it could be as follows: Figure 13 As shown, the wall component 32 is only provided on a portion of one side of the mounting surface 31.

[0074] In the above embodiments, a filter device 1 equipped with a transport cart 5 was described as an example. However, the presence or absence of a transport cart in the filter device of the present invention is arbitrary.

[0075] In the above embodiments, the structure in which the mounting surface member 51 is slidably supported on the main body portion 52a has been described as an example. However, in the case where a transport trolley is provided in the filter device of the present invention, the mounting surface member may also be fixed to the trolley.

[0076] In the above embodiments, a structure in which multiple ball support members 51a are provided on the top surface of the mounting surface member 51 has been described as an example. However, when a transport vehicle is provided in the filter device of the present invention, the presence or absence of a rotating body on the top surface of the mounting surface member 51 is arbitrary. Furthermore, when a rotating body is provided, it is not limited to ball support members; for example, it may be a roller or the like.

[0077] In the above embodiments, an example was described where the engaging groove 51b of the mounting surface member 51 and the abutment piece 33 of the tray 3 can engage. However, when a transport vehicle is provided in the filter device of the present invention, whether the mounting surface member and the tray can engage is arbitrary.

[0078] In the above embodiments, the structure in which the brake 52c is provided on the trolley 52 has been described as an example. However, the presence or absence of the brake is arbitrary when a transport trolley is provided in the filter device of the present invention.

[0079] Regarding other structures, it should be understood that the embodiments disclosed in this specification are illustrative in all respects, and the scope of the invention is not limited thereto. It should be readily understood that those skilled in the art can make appropriate changes without departing from the spirit of the invention. Therefore, other embodiments modified without departing from the spirit of the invention are obviously also within the scope of the invention.

Claims

1. A filter device comprising a housing and a tray, The housing has an opening for the filter element to enter and exit, and a door for closing the opening to accommodate the filter element. The tray is used to hold the filter elements. The filter device is characterized in that... The device includes a limiting component that, when the tray containing the filter element is housed within the housing, is positioned between the filter element and the door to restrict movement of at least one of the filter element and the tray. The limiting components are an abutment component disposed on the housing, an abutment piece disposed on the tray, and a stop component supported on the top surface of the housing. The abutment piece can be moved to an avoidance position and a restraint position. The avoidance position allows the tray to enter the interior of the housing from the opening. The restraint position, with the tray containing the filter element housed in the housing, allows the abutment piece and the abutment member to abut against each other to restrict the movement of the tray. The stop member can be moved to a state where it moves along the top surface of the housing without contacting the filter element, and to a state where it extends downward from the top surface of the housing and can contact the filter element.

2. A transport vehicle capable of transporting the filter element used in the filter device of claim 1, characterized in that, It has a mounting surface component and a trolley. The mounting surface component can mount the filter element. The trolley is capable of supporting the mounting surface component for movement.

3. The transport vehicle as described in claim 2, characterized in that, The mounting surface component can slide relative to the trolley.

4. The transport vehicle as described in claim 2, characterized in that, It has a rotating body disposed on the top surface of the mounting surface component.

5. The transport vehicle as described in claim 2, characterized in that, The mounting surface component and the tray can engage with each other.

6. The transport vehicle as described in claim 2, characterized in that, It has a travel restriction component that restricts the movement of the trolley.

7. A coating apparatus comprising a coating chamber for performing coating operations and a filter device from which air is supplied, characterized in that, The filter device has a housing, a tray, and limiting components. The housing has an opening for the filter element to enter and exit, and a door for closing the opening to accommodate the filter element. The tray is used to hold the filter elements. The limiting member is disposed between the filter element and the door when the tray containing the filter element is housed in the housing, thereby limiting the movement of at least one of the filter element and the tray. The limiting components are an abutment component disposed on the housing, an abutment piece disposed on the tray, and a stop component supported on the top surface of the housing. The abutment piece can be moved to a clearance position and a restraint position. The clearance position allows the tray to enter the interior of the housing from the opening. The restraint position, with the tray containing the filter element housed in the housing, allows the abutment piece and the abutment member to abut against each other to restrict the movement of the tray. The stop member can be moved to a state where it moves along the top surface of the housing without contacting the filter element, and to a state where it extends downward from the top surface of the housing and can contact the filter element.
