However, the technical solution of this patent still has the following defects in actual use: the connecting door needs to be opened every time the activated carbon is replaced, which exposes the internal structure of the equipment. Dust, debris, etc. can easily enter the device, which may affect the normal operation of other components and increase the difficulty and frequency of equipment maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a waste gas treatment system for pollution prevention and control, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment system for pollution prevention and control, comprising a treatment box, wherein an air inlet and an exhaust outlet are respectively provided on the two side walls of the treatment box;

[0006] The processing box is also equipped with a filter assembly for filtering exhaust gas.

[0007] The filter assembly includes a support frame with a hollow cavity in which a filter plate is supported, and limiting openings on both sides of the support frame.

[0008] The processing box is also provided with a locking and unlocking component, which includes a locking block. The locking block is installed on the two side walls of the processing box by a spring. Furthermore, a guide post extends from the end of the locking block. A first wedge is provided at the other end of the guide post. The guide post with the first wedge protrudes from the side wall of the processing box.

[0009] In a preferred embodiment, the locking and unlocking assembly further includes a U-shaped frame installed on the top of the processing box. The two ends of the U-shaped frame extend downward to form extensions with second wedges. The middle part of the U-shaped frame is connected to a screw via a clamping block. The screw is connected to the output end of a drive motor installed on a rectangular frame.

[0010] In a preferred embodiment, the locking and unlocking assembly further includes two sets of guide tubes symmetrically arranged on the top of the processing box, each set of guide tubes being connected through to both sides of the U-shaped frame.

[0011] In a preferred embodiment, the first wedge and the second wedge are provided with opposing and compatible inclined surfaces.

[0012] In a preferred embodiment, the size of the card block is adapted to the size of the limiting openings provided on both sides of the support frame.

[0013] In a preferred embodiment, a rectangular side frame is fixed in the middle of the processing box, the rectangular side frame has a through cavity structure in the middle, the support frame is installed on the rectangular side frame, and the support frame has a protruding end that extends to the outside of the cover plate of the processing box.

[0014] In a preferred embodiment, the rectangular side frame has a guide groove on its side wall, and a spring block is provided in the guide groove. One end of the spring block is fixed in the guide groove with a bolt, and the other end extends to the outside of the guide groove.

[0015] In a preferred embodiment, the filter plate has auxiliary handles extending upwards at both ends.

[0016] In a preferred embodiment, the cover plate is provided with a transparent window.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This waste gas treatment system for pollution control achieves relatively closed replacement of filter components through locking and unlocking components. It eliminates the need to open the connection door of the treatment box. Filter replacement can be completed simply by locking and unlocking the locking block and the limit port, and by pulling out the support bracket. During this process, the core filtration area inside the treatment box remains relatively closed, effectively preventing external dust and debris from entering the equipment and contaminating the internal components. This solves the problems of easy contamination and increased maintenance frequency caused by opening the connection door in the prior art, ensuring the long-term stable operation of the waste gas treatment system.

[0019] This waste gas treatment system for pollution prevention and control uses a locking and unlocking component with a structure that links a screw driven by a drive motor and a U-shaped frame. The automatic extension and retraction of the locking block is achieved through the cooperation of the inclined surfaces of the first and second wedges, replacing the manual operation of the locking components. This avoids problems such as insecure locking or difficulty in unlocking caused by uneven manual operation force. At the same time, it reduces the direct contact between the inside of the treatment box and the outside environment during the replacement process, reducing the risk of waste gas leakage.

[0020] This waste gas treatment system for pollution control uses a spring block that can pop out a portion of the support frame when unlocked, eliminating the need for manual dragging or prying. Combined with the protrusion at the end of the support frame, it facilitates the quick removal of the support frame and filter plate from the treatment box by subsequent staff, greatly improving the replacement efficiency of the activated carbon in the filter plate.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0028] Please see Figures 1-4This utility model provides a waste gas treatment system for pollution prevention and control, including a treatment box 1. The treatment box 1 has an air inlet 2 and an exhaust outlet 3 on its two side walls, respectively. The treatment box 1 also has a filter assembly 5 for filtering waste gas. The filter assembly 5 includes a support frame 51 with a hollow cavity in which a filter plate 52 is supported. Limiting openings 511 are provided on both sides of the support frame 51. The treatment box 1 also has a locking and unlocking assembly 6, which includes a locking block 61. The locking block 61 is mounted on the two side walls of the treatment box 1 by a spring 611. The end of 61 also extends a guide post 62, and the other end of the guide post 62 is provided with a first wedge 621. The guide post 62 with the first wedge 621 extends out of the side wall of the processing box 1. The locking and unlocking assembly 6 also includes a U-shaped frame 64 installed on the top of the processing box 1. The two ends of the U-shaped frame 64 extend downward to form an extension with a second wedge 63. The first wedge 621 and the second wedge 63 are provided with opposite and compatible inclined surfaces. The middle part of the U-shaped frame 64 is connected to the screw 66 through a clamping block 65. The screw 66 is connected to the output end of the drive motor 67 installed on the rectangular frame 68.

[0029] In this embodiment, the filter component 5 can be replaced in a relatively closed manner by locking and unlocking component 6. There is no need to open the cover 11 of the treatment box 1. The activated carbon particles can be replaced simply by locking and unlocking the card block 61 and the limiting port 511 and pulling out the support bracket 51. During this process, the core filtration area inside the treatment box 1 remains relatively closed, which effectively prevents external dust and debris from entering the internal components of the equipment and contaminating them, thus ensuring the long-term stable operation of the waste gas treatment system.

[0030] The drive motor 67 drives the screw 66 to rotate, which in turn drives the U-shaped frame 64 to move linearly. By utilizing the inclined surfaces of the first wedge 621 and the second wedge 63, the rotational motion is converted into the horizontal extension and retraction of the locking block 61, thereby achieving automatic locking and unlocking of the filter assembly 5. Compared with the traditional manual bolt fixing method, this structure can complete the operation in a few seconds, significantly shortening the equipment maintenance downtime.

[0031] Please see Figure 1 and Figure 4 The locking and unlocking component 6 also includes two sets of guide tubes 69 symmetrically arranged on the top of the processing box 1, each set of guide tubes 69 being connected through to both sides of the U-shaped frame 64.

[0032] In this embodiment, two sets of guide tubes 69 are symmetrically arranged and pass through both sides of the U-shaped frame 64 to form a vertical guide structure. When the drive motor 67 drives the screw 66 to transmit power, the guide tubes 69 restrict the lateral displacement of the U-shaped frame 64, so that it can only move in a straight line along the axial direction, thus eliminating the misalignment problem between the first wedge 621 and the second wedge 63 caused by lateral offset.

[0033] Please see Figure 3 and Figure 4The size of the card block 61 is compatible with the size of the limiting ports 511 provided on both sides of the support frame 51.

[0034] In this embodiment, by matching the size of the locking block 61 with that of the limiting port 511, the stability of the support bracket 51 can be ensured when the locking block 61 is embedded in the limiting port 511.

[0035] Please see Figure 2 and Figure 3 A rectangular side frame 4 is fixed in the middle of the processing box 1. The rectangular side frame 4 has a through cavity 41 in the middle. A support frame 51 is installed on the rectangular side frame 4. The support frame 51 has a protrusion 512 that extends to the outside of the cover plate 11 of the processing box 1. The cover plate 11 is provided with a transparent window 12. The side wall of the rectangular side frame 4 is provided with a guide groove 412. A spring block 7 is provided in the guide groove 412. One end of the spring block 7 is fixed in the guide groove 412 with a bolt, and the other end extends to the outside of the guide groove 412.

[0036] In the above scheme, it should be noted that: the spring block 7 is specifically composed of two mounting blocks and a spring, and the two ends of the spring are fixedly connected to the two mounting blocks respectively. One mounting block is fixed inside the guide groove 412 by bolts, and the other mounting block extends to the outside of the guide groove 412 and contacts the support bracket 51.

[0037] In this embodiment, the through cavity 41 structure of the rectangular side frame 4 provides a rigid support frame for the support frame 51. The spring block 7 is compressed and stores energy when the support frame 51 is locked. When unlocked, the support frame 51 is automatically ejected outward by the elastic force. The protrusion 512 can be exposed outside the cover plate 11 without manual dragging, which solves the problem of the support frame 51 being stuck and difficult to remove in the traditional structure. This makes the replacement operation easier. In addition, the transparent window 12 on the cover plate 11 allows direct observation of the usage status of the filter material inside the support frame 51 (such as the color change of activated carbon), so that the operator can determine whether the filter material needs to be replaced.

[0038] Please see Figure 3 The filter plate 52 has auxiliary handles 521 extending upwards from both ends.

[0039] The working principle and usage process of this utility model are as follows: First, the waste gas to be treated enters from the air inlet 2 of the treatment box 1. When it flows through the cavity 41 of the rectangular side frame 4, it is purified by the activated carbon in the filter plate 52 supported by the filter assembly 5. The purified waste gas is discharged through the exhaust port 3.

[0040] At this time, the locking and unlocking component 6 is in the locked state, and the card block 61 is embedded in the limiting port 511 of the support bracket 51 under the elastic force of the spring 611. When the operator observes the usage status of the activated carbon in the filter plate 52 through the transparent window 12 on the cover plate 11 (such as the activated carbon color darkening, blockage, etc.) and determines that it needs to be replaced.

[0041] When replacement is needed, the drive motor 67 is started, which drives the screw 66 to rotate. Through the clamping block 65, the U-shaped frame 64 moves upward linearly along the guide tube 69. The second wedges 63 at both ends of the U-shaped frame 64 move upward accordingly, releasing the pressure on the first wedge 621. The locking block 61 is disengaged from the limiting port 511 under the restoring force of the spring 611, completing the unlocking. After unlocking, the spring block 7 in the guide groove 412 of the rectangular side frame 4 releases its stored energy, and the elastic force pushes the support frame... 51 pops outward, so that one end with the protrusion 512 protrudes from the outside of the cover plate 11. The operator holds the protrusion 512 and pulls the support frame 51 out of the rectangular side frame 4. The filter plate 52 and the old activated carbon inside are taken out of the support frame 51 by the auxiliary handle 521. After replacing the new activated carbon, the filter plate 52 is put back into the hollow cavity of the support frame 51. The support frame 51 is pushed back into the rectangular side frame 4 until the support frame 51 is completely reset. At this time, the spring block 7 is compressed.

[0042] Then, the drive motor 67 is started to reverse, and the screw 66 drives the U-shaped frame 64 to move downward along the guide tube 69. The second wedges 63 at both ends of the U-shaped frame 64 press the first wedge 621 through the inclined surface, push the guide post 62 to drive the locking block 61 to overcome the elastic force of the spring 611 and move inward, so that the locking block 61 is finally embedded in the limiting port 511 of the support frame 51 and the locking is completed.

[0043] After locking, the treatment box 1 returns to a closed state, and exhaust gas can be reintroduced for filtration.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
