[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 6 The present invention provides an embodiment of a waste gas catalytic combustion treatment device, comprising a treatment cylinder 1, which is a hollow cylinder. The inner wall of the treatment cylinder 1 is provided with a heating wire for heating. An air inlet pipe 2 is fixedly connected to the lower side wall of the treatment cylinder 1. The air inlet pipe 2 is used to discharge waste gas into the treatment cylinder 1 so that the waste gas can be treated by catalytic combustion. An air outlet pipe 3 is fixedly connected to the top of the treatment cylinder 1. The air outlet pipe 3 is used to discharge the waste gas after filtration and catalytic combustion.

[0035] Reference Figure 2 - Figure 4 The processing cylinder 1, located above the air inlet pipe 2, is equipped with a filter mechanism 4. The filter mechanism 4 includes a filter plate 41, which is used to filter impurities mixed in the exhaust gas. A slider 42 is fixedly connected to the outer wall of the filter plate 41. A groove 43 is opened on the inner wall of the processing cylinder 1. The inner wall of the groove 43 is slidably connected to the outer wall of the slider 42. The slider 42 slides up and down relative to the groove 43. The bottom end of the slider 42 is elastically connected to the bottom end of the groove 43 by a spring 44. One end of the spring 44 is fixedly connected to the bottom end of the slider 42, and the other end of the spring 44 is fixedly connected to the bottom end of the groove 43. An mounting block 45 is fixedly connected to the inner wall of the filter plate 41. The mounting block 45 is annular in shape and is located at the center of the filter plate 41. A brush 46 is rotatably connected to the inner wall of the mounting block 45. The length of the brush 46 is longer than the radius of the filter plate 41, and the bristles of the brush 46 are located on the top.

[0036] Reference Figure 2 , Figure 4 and Figure 5 The inner wall of the brush 46 and the interior of the processing cylinder 1 are jointly provided with a starting component 47. The starting component 47 includes a mounting bracket 471. The outer wall of the mounting bracket 471 is fixedly connected to the inner wall of the processing cylinder 1. A control rod 472 is fixedly connected to the inner side of the mounting bracket 471. The control rod 472 is cylindrical and is located at the center of the processing cylinder 1. A control ball 473 is fixedly connected to the outer wall of the control rod 472. A control tube 474 is fixedly connected to the bottom end of the brush 46. The inner diameter of the control tube 474 matches the outer diameter of the control rod 472. A control groove 475 is opened on the inner wall of the control tube 474. The control groove 475 is spiral in shape, and the width of the control groove 475 matches the diameter of the control ball 473.

[0037] Reference Figure 6 and Figure 7 The inner wall of the processing cylinder 1 and the inner wall of the slider 42 are both provided with a weight control component 48. The weight control component 48 is used to ensure that when some impurities adhere to the filter plate 41, the filter plate 41 will not move downward immediately. Instead, it will only move downward when more impurities adhere to the bottom of the filter plate 41, and after moving downward, it can immediately move a relatively long distance to ensure that the expected effect is achieved. The weight control component 48 includes a mounting groove 481, which is opened in the inner wall of the processing cylinder 1. A weight control block 482 is slidably connected to the inner wall of the mounting groove 481. The outer wall of the weight control block 482 is elastically connected to the inner wall of the mounting groove 481 by a spring 483. One end of spring 482 is fixedly connected to the end of the control weight 482 away from the slide groove 43. The other end of spring 483 is fixedly connected to the inner wall of the mounting groove 481. The control weight 482 is rectangular in shape, and the control weight 482 is provided with chamfers at the top and bottom of the end away from spring 483. The slope of the lower chamfer of the control weight 482 is greater than the slope of the upper chamfer. The force required to push the control weight 482 through the upper inclined surface is greater than the elastic force of spring 44. The elastic force of spring 44 is greater than the sum of the weight of the filter plate 41 when there are no impurities and the force required to push the control weight 482 from below. The inner wall of the slider 42 is provided with an insertion hole 484.

[0038] Reference Figure 1 , Figure 2 and Figure 6 The inner wall of the treatment cylinder 1, which is located above the filter mechanism 4, is fixedly connected to a catalyst plate 5. The inner wall of the catalyst plate 5 has multiple holes, and the holes are spiral in shape. The bottom end of the treatment cylinder 1 is threadedly connected to a collection cylinder 6, which is cylindrical in shape.

[0039] Working principle: During use, the exhaust gas enters the treatment cylinder 1 through the inlet pipe 2, and after passing through the filter plate 41 and the catalytic plate 5, it is discharged through the outlet pipe 3.

[0040] When the exhaust gas passes through the filter plate 41, some of the impurities mixed in the exhaust gas are filtered by the filter plate 41, so some of the impurities stick to the bottom of the filter plate 41, and some of the impurities fall directly into the inside of the collection cylinder 6 under the action of gravity.

[0041] When a lot of impurities adhere to the lower end of the filter plate 41, its weight increases. When its weight is large enough to push the control block 482 through the inclined surface above the control block 482, it pushes the control block 482, thereby causing the control block 482 to enter the interior of the mounting groove 481. At the same time, since the weight of the filter plate 41 was already able to overcome the elastic force of the spring 44, but could not move downward due to the restriction of the control block 482, the filter plate 41 will move downward quickly after the control block 482 leaves the insertion hole 484.

[0042] When the filter plate 41 moves downward, the filter plate 41 drives the brush 46 and the control tube 474 to move downward together. Since the control ball 473 is inside the control groove 475, the spiral surface of the control groove 475 squeezes the control ball 473 during the downward movement of the control tube 474, thereby causing the control tube 474 to rotate under the relative squeezing action of the control ball 473, and driving the brush 46 to rotate, so that the brush 46 cleans the bottom of the filter plate 41 during the rotation.

[0043] After some impurities are removed, the filter plate 41 becomes lighter, so its weight is less than the elastic force of the spring 44. Under the action of the elastic force, the spring 44 drives the slider 42 and the filter plate 41 to move upward. At this time, the control ball 473 is squeezed relative to the control groove 475, causing the control tube 474 to rotate in the opposite direction, which in turn causes the brush 46 to rotate in the opposite direction, thereby achieving the effect of further cleaning the filter plate 41.

[0044] When the slider 42 and the filter plate 41 move upward, the bottom chamfer of the control weight 482 is inclined at a large angle, so it can be pushed into the mounting groove 481 by its bottom inclined surface. After the filter plate 41 moves upward to the highest point, the control weight 482 is reset by the second spring 483, so that the filter plate 41 returns to the initial state, which is convenient for continuous use of the equipment.

[0045] At this time, when the staff needs to clean the equipment, they only need to rotate the collection cylinder 6 to separate it from the processing cylinder 1, and the impurities inside the processing cylinder 1 can be cleaned.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
