Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment filtration device. Background Technology
[0002] Waste gas treatment filtration technology is a key technology used to reduce or remove harmful gases and particulate matter generated during industrial production. Activated carbon adsorption treatment is a waste gas treatment filtration method. The waste gas pipeline is connected to one end of the activated carbon box and enters the interior, where the activated carbon inside adsorbs and filters the organic molecular particles in the waste gas.
[0003] When using an activated carbon adsorption filter, the activated carbon filter layer needs to be installed inside the drawer box, and then the drawer box is inserted into the pipe of the filter device to filter the exhaust gas. Since the drawer box is a plug-in type, there may be a certain gap between the surface of the drawer box and the drawer box after it is inserted into the drawer slot. This can cause the exhaust gas to leak through the gap when it enters the filter device, affecting the filtration effect of the filter device. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that, since the drawer box is a plug-in type, there may be a certain gap between the surface of the drawer box and the drawer box after it is inserted into the drawer slot, which will cause the exhaust gas to leak through the gap when it enters the filter device, thus affecting the filtration effect of the filter device. Therefore, an exhaust gas treatment filter device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waste gas treatment and filtration device, comprising a housing, with an inlet pipe and an outlet pipe respectively provided at both ends of the housing, two door panels rotatably connected to one side of the housing, a plurality of drawer slots opened inside the housing, drawer boxes slidably inserted into the inner wall of the drawer slots, a sealing device provided at one end of the drawer box, the sealing device comprising a screw, one end of the screw being rotatably connected to one side of the drawer box, an X-shaped rod threadedly connected to the outer surface of the screw, rectangular blocks fixedly connected to the four corners of the X-shaped rod, the outer surface of the rectangular blocks sliding on one side of the inner wall of the drawer box, a rectangular frame fixedly connected to the end of the rectangular blocks away from the X-shaped rod, a rectangular groove opened inside the drawer box, the outer surface of the rectangular frame sliding on the inner wall of the rectangular groove, the size and shape of the outer surface of the rectangular frame matching the size and shape of the inner wall of the rectangular groove, one end of the rectangular groove penetrating the inner wall of the drawer box, an airbag plate fixedly connected to the outer surface of the drawer box near the rectangular groove, the airbag plate being located outside the rectangular groove.
[0006] The effect achieved by the above components is as follows: By setting up the airbag plate, when installing the filter device, the exhaust gas delivery pipe is connected to the air inlet pipe at one end of the box, and the exhaust pipe at one end of the box is connected to the output pipe. Several activated carbon filter layers are placed inside the drawer box. Then, the drawer box is inserted into the drawer slot on one side of the box. After the drawer box is inserted into the drawer slot, the screw can be rotated on one side of the drawer box to control the X-shaped rod to move towards the drawer box from the outer surface of the screw. This causes the rectangular blocks at the four corners of the X-shaped rod to slide on the inner wall of the drawer box, controlling the rectangular frame to slide towards the airbag plate from the inner wall of the rectangular slot. This pushes the air inside the rectangular slot to one side of the airbag plate, causing the airbag plate to expand outward and fit tightly against the contact point between the outer surface of the drawer box and the outer surface of the box. This further seals the contact point between the drawer box and the box, minimizing gaps at the contact point and preventing exhaust gas leakage.
[0007] Preferably, one end of the screw is fixedly connected to an operating block, and the outer surface of the operating block is provided with several protrusions.
[0008] The effect achieved by the above components is that the protrusion on the outer surface of the operating block makes it easier to rotate the screw to control the movement of the X-shaped rod and prevents the hand from slipping.
[0009] Preferably, a baffle is fixedly connected to the outer surface of the drawer near the airbag sheet, and the baffle is located on the outside of the airbag sheet.
[0010] The effect achieved by the above components is that the baffle can restrict the shape of the outer surface of the inflated airbag and its position on one side of the drawer, so as to avoid the airbag surface from expanding in a different shape and affecting the sealing effect.
[0011] Preferably, a sealing sheet is fixedly connected to the outer surface of the rectangular block, and the sealing sheet is made of rubber.
[0012] The effect achieved by the above components is as follows: after rotating the screw controls the movement of the X-shaped rod and the rectangular block to push the rectangular frame and inflate the airbag, the rubber sealing sheet on the outer surface of the rectangular block will adhere to the outer surface of the drawer, further sealing the contact point between the rectangular block and the outer surface of the drawer, and minimizing the leakage of air inside the rectangular groove through the contact point between the rectangular block and the inner wall of the drawer.
[0013] Preferably, a plurality of positioning devices are provided on the outer surface of the box near the draw slot. The positioning device includes a slider. A plurality of sliding grooves are opened on the outer surface of the box. Two sliding grooves are respectively located on both sides of the outer surface of the box near the draw slot. The outer surface of the slider is slidably connected to the inner wall of the sliding groove. A spring is provided at one end of the slider. The two ends of the spring are respectively fixedly connected to one end of the inner wall of the sliding groove and one end of the slider.
[0014] The effect achieved by the above components is as follows: when the drawer box is inserted into the drawer slot, the outermost surface of the drawer box contacts one end of the two sliders on both sides near one end of the drawer slot, which pushes the two sliders to slide into the drawer slot and compresses the springs. After the drawer box is fully inserted into the drawer slot, the springs inside the two drawer slots will return to their original state and push the sliders to slide out of the drawer slot, so that one side of the two sliders is attached to the outside of the drawer box, fixing the position of the drawer box inside the drawer slot and minimizing the movement of the drawer box inside the drawer slot, which would affect the sealing effect of the sealing device.
[0015] Preferably, an arc-shaped piece is fixedly connected to one end of the slider, and the edge of the arc-shaped piece away from the slider is arc-shaped.
[0016] The effect achieved by the above components is that when the outermost surface of the drawer comes into contact with the arc-shaped piece on the outer surface of the slider, it is easier to push the slider into the interior of the groove and they are less likely to get stuck together.
[0017] Preferably, a round rod is fixedly connected to one side of the slider, and the outer surface of the round rod slides on the inner wall of the box.
[0018] The effect achieved by the above components is that when the slider moves, the round rod will slide on the inner wall of the box. The round rod can further limit the angle between the slider and the groove, and minimize the wobbling and skew of the slider when it moves.
[0019] Preferably, the diameter of the round rod is slightly smaller than the inner diameter of the spring, and the spring is located on the outside of the round rod.
[0020] The effect achieved by the above components is that when the slider moves and causes the spring to deform, the spring will move on the outside of the round rod. The round rod can reinforce the internal shape of the spring and avoid lateral twisting of the spring as much as possible, which would affect normal use.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a sealing device, after the drawer box is inserted into the drawer slot, the rectangular frame is controlled to slide by rotating the screw, pushing the air inside the rectangular slot to one side of the airbag plate, causing the airbag plate to expand outward and fit tightly against the contact point between the outer surface of the drawer box and the outer surface of the box, further sealing the contact point between the drawer box and the box, and minimizing the possibility of gaps at the contact point between the drawer box and the box, which could lead to exhaust gas leakage.

[0030] Example 1, as Figure 1-6As shown, a waste gas treatment and filtration device includes a housing 1. An inlet pipe and an outlet pipe are respectively installed at both ends of the housing 1. Two door panels 6 are rotatably connected to one side of the housing 1. Several drawer slots 4 are provided inside the housing 1. Drawer boxes 5 are slidably inserted into the inner walls of the drawer slots 4. A sealing device 2 is provided at one end of each drawer box 5. The sealing device 2 includes a screw 21, one end of which is rotatably connected to one side of the drawer box 5. An X-shaped rod 22 is threaded onto the outer surface of the screw 21. The four corners of the X-shaped rod 22 are respectively fixed... A rectangular block 23 is connected, and the outer surface of the rectangular block 23 slides on one side of the inner wall of the drawer 5. A rectangular frame 24 is fixedly connected to the end of the rectangular block 23 away from the X-shaped rod 22. A rectangular groove 25 is opened inside the drawer 5, and the outer surface of the rectangular frame 24 slides on the inner wall of the rectangular groove 25. The size and shape of the outer surface of the rectangular frame 24 are adapted to the size and shape of the inner wall of the rectangular groove 25. One end of the rectangular groove 25 penetrates the inner wall of the drawer 5, and an air valve is fixedly connected to the side of the outer surface of the drawer 5 near the rectangular groove 25. The airbag 26 is located outside the rectangular groove 25. By setting the airbag 26, when installing the filter device, the exhaust gas conveying pipe is connected to the inlet pipe at one end of the housing 1, and the outlet pipe at one end of the housing 1 is connected to the outlet pipe. Several activated carbon filter layers are placed inside the drawer box 5. Then, the drawer box 5 is inserted into the drawer groove 4 on one side of the housing 1. After the drawer box 5 is inserted into the drawer groove 4, the screw 21 can be rotated on one side of the drawer box 5 to control the X-shaped rod 22 to face the drawer box from the outer surface of the screw 21. The movement of the X-shaped rod 22 in the direction of 5 causes the rectangular blocks 23 at the four corners of the X-shaped rod 22 to slide on the inner wall of the drawer 5. The rectangular frame 24 is controlled to slide on the inner wall of the rectangular groove 25 towards the airbag plate 26, pushing the air inside the rectangular groove 25 to one side of the airbag plate 26. This causes the airbag plate 26 to expand outward and fit tightly against the contact point between the outer surface of the drawer 5 and the outer surface of the box 1, further sealing the contact point between the drawer 5 and the box 1, and minimizing the possibility of gaps at the contact point between the drawer 5 and the box 1, which could lead to exhaust gas leakage.
[0031] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown in this embodiment: one end of the screw 21 is fixedly connected to the operating block 27. The outer surface of the operating block 27 is provided with several protrusions. Holding the protrusions on the outer surface of the operating block 27 makes it easier to rotate the screw 21 to control the movement of the X-shaped rod 22 and prevents the hand from slipping.
[0032] Reference Figure 4-6As shown in this embodiment: A baffle 28 is fixedly connected to the outer surface of the drawer box 5 near the side of the airbag 26. The baffle 28 is located outside the airbag 26. The baffle 28 can restrict the shape of the outer surface of the inflated airbag 26 and its position on one side of the drawer box 5, so as to avoid the airbag 26 from having an uneven expansion shape, which would affect the sealing effect. A sealing sheet 29 is fixedly connected to the outer surface of the rectangular block 23. The sealing sheet 29 is made of rubber. After rotating the screw 21 to control the X-shaped rod 22 and the rectangular block 23 to move and push the rectangular frame 24 to inflate the airbag 26, the rubber sealing sheet 29 on the outer surface of the rectangular block 23 will stick to the outer surface of the drawer box 5, further sealing the contact point between the rectangular block 23 and the outer surface of the drawer box 5, and preventing the air inside the rectangular groove 25 from leaking through the contact point between the rectangular block 23 and the inner wall of the drawer box 5.
[0033] Reference Figure 1-3 As shown in this embodiment: several positioning devices 3 are provided on the outer surface of the box 1 near the drawer 4. The positioning device 3 includes a slider 32. Several sliding grooves 31 are formed on the outer surface of the box 1. Two sliding grooves 31 are respectively located on both sides of the outer surface of the box 1 near the drawer 4. The outer surface of the slider 32 is slidably connected to the inner wall of the sliding groove 31. A spring 33 is provided at one end of the slider 32. The two ends of the spring 33 are respectively fixedly connected to one end of the inner wall of the sliding groove 31 and one end of the slider 32. By setting the slider 32, the drawer 5 is inserted into the drawer 4. When the outermost surface of the drawer box 5 contacts one end of the two sliders 32 on both sides near one end of the drawer groove 4, it will push the two sliders 32 to slide into the groove 31 and compress the spring 33. After the drawer box 5 is fully inserted into the drawer groove 4, the springs 33 inside the two grooves 31 will return to their original state and push the sliders 32 to slide out of the groove 31, so that one side of the two sliders 32 is attached to the outside of the drawer box 5, fixing the position of the drawer box 5 inside the drawer groove 4, and avoiding the movement of the drawer box 5 inside the drawer groove 4 as much as possible, so as to affect the sealing effect of the sealing device 2.
[0034] Reference Figure 2-3 As shown in this embodiment: one end of the slider 32 is fixedly connected to an arc-shaped piece 35. The edge of the arc-shaped piece 35 away from the slider 32 is arc-shaped. When the outermost surface of the drawer box 5 contacts the arc-shaped piece 35 on the outer surface of the slider 32, it is easier to push the slider 32 to slide into the interior of the slide groove 31 and they are less likely to get stuck together.
[0035] Reference Figure 2-3As shown in this embodiment: a round rod 34 is fixedly connected to one side of the slider 32. The outer surface of the round rod 34 slides on the inner wall of the housing 1. When the slider 32 moves, the round rod 34 will slide on the inner wall of the housing 1. The round rod 34 can further limit the angle between the slider 32 and the groove 31, and avoid the slider 32 from shaking or deviating from its angle as much as possible. The diameter of the round rod 34 is slightly smaller than the inner diameter of the spring 33. The spring 33 is located outside the round rod 34. When the slider 32 moves and causes the spring 33 to deform, the spring 33 will move outside the round rod 34. The round rod 34 can reinforce the internal shape of the spring 33, and avoid the spring 33 from twisting laterally and affecting normal use as much as possible.
[0036] Working principle: When installing the filter device, connect the exhaust gas delivery pipe to the inlet pipe at one end of the housing 1, and connect the outlet pipe at one end of the housing 1 to the outlet pipe. Place several activated carbon filter layers inside the drawer box 5, and then insert the drawer box 5 into the drawer slot 4 on one side of the housing 1. When the outermost surface of the drawer box 5 contacts one end of the two sliders 32 near the two sides of the drawer slot 4, it will push the two sliders 32 to slide into the slide groove 31 and compress the spring 33. After the drawer box 5 is fully inserted into the drawer slot 4, the springs 33 inside the two slide grooves 31 will return to their original state and push the sliders 32 to slide out of the slide groove 31, so that one side of the two sliders 32 is attached to the outside of the drawer box 5, fixing the position of the drawer box 5 inside the drawer slot 4. After the drawer box 5 is inserted into the drawer slot 4, the screw can be rotated on one side of the drawer box 5. 21. Control the X-shaped rod 22 to move towards the drawer box 5 from the outer surface of the screw 21, so that the rectangular blocks 23 at the four corners of the X-shaped rod 22 slide on the inner wall of the drawer box 5. Control the rectangular frame 24 to slide towards the airbag plate 26 from the inner wall of the rectangular groove 25, so that the air inside the rectangular groove 25 is pushed to one side of the airbag plate 26, so that the airbag plate 26 expands outward and fits tightly against the contact point between the outer surface of the drawer box 5 and the outer surface of the box 1, further sealing the contact point between the drawer box 5 and the box 1, and avoiding gaps at the contact point between the drawer box 5 and the box 1 as much as possible, which could lead to exhaust gas leakage. Then push the two door panels 6 to rotate and fit against one side of the box 1, sealing one side of the box 1, so that the exhaust gas enters the interior of the box 1 through the air inlet pipe, and the organic gas particles in the exhaust gas are adsorbed and filtered by the activated carbon filter layer inside the drawer box 5.
