The treated exhaust gas is discharged to avoid environmental pollution. The upper surface of the collection box 6 is provided with a disassembly and assembly component 4. The filter component 5 includes a filter plate 51. The filter plate 51 penetrates and slides on the front surface of the rectangular shell 2. The filter plate 51 can prevent the tin powder from being sucked out to ensure the output of the product. The front surface of the filter plate 51 penetrates and is rotatably connected with a rotating rod 54. The rotating rotating rod 54 then drives the rectangular bar 56 to rotate and separate it from the inner wall of the fixed shell 52. At this time, the filter plate 51 can be disassembled. The rear surface of the rotating rod 54 is fixedly connected with a rectangular bar 56. The rectangular bar 56 rotates on the inner wall of the front end of the filter plate 51.

[0034] Reference Figure 1 , Figure 3The disassembly and assembly component 4 includes a cover plate 41, and an exhaust pipe is provided on the upper surface of the cover plate 41 to facilitate the discharge of purified exhaust gas. The lower surface of the cover plate 41 contacts the upper surface of the collecting box 6. The lower surface of the cover plate 41 is fixedly connected with an elastic telescopic rod 44. The elastic telescopic rod 44 is a prior art, which is connected by multiple groups of elastic sleeve rods, and the connection distance between the multiple groups of elastic sleeve rod assemblies can be adjusted according to the adsorption plate provided inside the frame 45. The lower surface of the elastic telescopic rod 44 is fixedly connected with a frame 45. The frame 45 is divided into two layers, an activated carbon adsorption plate can be placed inside one layer, and a sponge plate can be placed on the other layer. Since the activated carbon adsorption plate and the sponge plate are prior art, this design will not be introduced and demonstrated in detail. A rubber block 43 is fixedly connected to the right surface of the bottom end of the cover plate 41.

[0035] Reference Figure 2 , Figure 4 The filter assembly 5 also includes a fixed shell 52, which is fixedly connected to the right side of the front surface of the rectangular shell 2 adjacent to the filter plate 51. The rectangular bar 56 contacts the inner wall of the fixed shell 52, and the inner wall of the fixed shell 52 is adapted to the rectangular bar 56 to ensure the stability of the connection. The outer wall of the rotating rod 54 is sleeved with a scroll spring 55, which has a certain elasticity. When the rotating rod 54 is not rotated, the rectangular bar 56 is always kept in a horizontal state through its own elasticity to ensure the stability of its limiting position. One end of the scroll spring 55 is fixedly connected to the rear surface of the rotating rod 54, and the other end of the scroll spring 55 is fixedly connected to the front surface of the filter plate 51.

[0036] Reference Figure 2 , Figure 5 The filter assembly 5 also includes a scraper 57, which contacts the left surface of the filter plate 51 to prevent the tin powder from sticking and being pulled out, thereby improving practicality. The scraper 57 is fixedly connected to the inner wall of the rectangular shell 2, and the right surface of the rear end of the scraper 57 contacts the left surface of the filter plate 51. The front end of the outer wall of the filter plate 51 is fixedly connected with a sealing ring 53. The sealing ring 53 is a prior art, which can ensure the sealing of the filter plate 51 and avoid exhaust gas leakage. The sealing ring 53 contacts the inner wall of the sealing groove 7.

[0037] Reference Figure 3 , Figure 6A snap-in groove 9 is provided on the upper surface of the collection box 6, and the snap-in groove 9 is matched with the bottom end of the cover plate 41 to ensure the stability of the connection. A rectangular groove 8 is provided on the inner wall of the snap-in groove 9. The bottom end of the cover plate 41 contacts the inner wall of the snap-in groove 9, and the rubber block 43 contacts the inner wall of the rectangular groove 8. The rubber block 43 is made of rubber material and has a certain elasticity. It will deform after being squeezed, and will immediately recover when the pressure is released. Its right surface is set as an arc surface to ensure that it can smoothly enter the inner wall of the snap-in groove 9 and the inner wall of the rectangular groove 8, thereby ensuring the quickness of disassembly and assembly. A prompt plate 42 is fixedly connected to the rear end of the upper surface of the frame 45, and the prompt plate 42 penetrates and slides and is connected to the upper surface of the cover plate 41.

[0038] Reference Figure 1 The right surface of the collecting box 6 is fixedly connected with an exhaust pump 3. The exhaust pump 3 is a prior art, which can extract the gas inside the drying tank 1 and discharge it into the inside of the collecting box 6 to prevent the exhaust gas from leaking. The upper surface of the exhaust pump 3 is fixedly connected to the top of the right surface of the rectangular shell 2 through a pipeline, and the right surface of the exhaust pump 3 is fixedly connected to the bottom end of the right surface of the collecting box 6 through a pipeline.

[0039] Working principle: When in use, the vacuum pump 3 can be started, and the vacuum pump 3 will absorb the exhaust gas inside the drying tank 1, and discharge the sucked exhaust gas into the collection box 6 for exhaust gas treatment. In the process of absorbing the exhaust gas, the tin powder mixed in the exhaust gas will be filtered out by the filter plate 51, and the filtered tin powder will return to the interior of the drying tank 1 again to ensure the output.

[0040] When the filter plate 51 needs to be disassembled and replaced, it is only necessary to rotate the rotating rod 54, which will drive the scroll spring 55 to rotate and twist it. At the same time, the rotating rod 54 will drive the rectangular bar 56 to rotate and separate it from the inner wall of the fixed shell 52. At this time, the filter plate 51 can be pulled out. In the process of pulling out the filter plate 51, the scraper 57 will scrape the surface of the filter plate 51 to prevent the powder adhering to the surface of the filter plate 51 from being taken out, and the scraped powder will fall back to the drying tank along the inclined surface 10. 1, when installing, the filter plate 51 is inserted into the interior of the rectangular shell 2, and the rotating rod 54 is rotated at the same time, and the rotating rod 54 will cause the scroll spring piece 55 to twist and deform until the sealing ring 53 completely enters the inner wall of the sealing groove 7, and the rectangular strip 56 will overlap with the inner wall of the fixed shell 52. At this time, the rotating rod 54 is loosened, and the scroll spring piece 55 will drive the rotating rod 54 to reverse and reset through its own elasticity, and the rectangular strip 56 will also rotate and insert into the inner wall of the fixed shell 52, so as to limit the filter plate 51, which is quick and convenient.

[0041] After the exhaust gas enters the interior of the collecting box 6 through the vacuum pump 3, it will react with the treatment liquid inside it to generate gas. At this time, the activated carbon adsorption plate on the inner wall of the collecting box 6 adsorbs and purifies the harmful gas to ensure that clean air is discharged. After the activated carbon has adsorbed the gas, there will be a certain amount of mass deformation. At this time, the frame 45 will slowly descend, and at the same time, the frame 45 will stretch the elastic telescopic rod 44 and drive the prompt plate 42 to slide downward. The worker can observe the length of the prompt plate 42 exposed to the outside to judge the service life of the activated carbon adsorption plate. When it needs to be replaced, it only needs to pull the cover plate 41. The bottom end of the cover plate 41 will be detached from the inner wall of the clamping groove 9, and the rubber clamping block 43 will be squeezed and detached from the inner wall of the heavy rectangular groove 8. It is quick and convenient to take the activated carbon adsorption plate out of the inner wall of the frame 45. When installing, put the frame 45 into the inner wall of the collecting box 6, and insert the bottom end of the cover plate 41 into the inner wall of the clamping groove 9. The subsequent structural matching method is the same as above.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
