Description

Technical Field

[0001] The utility model relates to the field of incinerator filtration, in particular to a filtering device for an incinerator torch head. Background Art

[0002] An incinerator is a harmless treatment equipment commonly used in the harmless treatment of medical and domestic waste and animals. Its principle is to utilize the combustion of fuels such as coal, oil, and gas to incinerate and carbonize the objects to be treated at high temperatures to achieve the purpose of disinfection.

[0003] In the prior art, an incinerator needs to release a large amount of flue gas to the outside while burning, and the flue gas contains a large amount of impurities, so the flue gas emitted by the incinerator needs to be filtered. In the prior art, a filter is provided at the smoke outlet to filter the impurities in the flue gas, thereby achieving the purpose of flue gas filtering.

[0004] In the prior art, the filter is directly connected by bolts or welded to the smoke outlet. After long-term use, a large amount of impurities adhere to the surface of the filter, which clogs the filter holes and affects the air permeability of the filter. At this time, the filter needs to be cleaned and replaced, and the filter needs to be removed from the device to complete the cleaning and replacement, which reduces work efficiency and shortens the service life of the filter.

At this time, the threaded head is meshed with the thread below the inner wall of the limiting cylinder. The rotating shaft is continuously rotated so that the threaded head drives the rotating shaft to move downward, thereby causing the carrying mechanism and the filter bin to move downward at the same time. When the threaded head moves to the end of the limiting cylinder, the sliding block and the threaded head are in a tensioned state. The rotating shaft is continuously rotated to drive the threaded head to rotate, thereby causing the sliding block to disengage from the threaded head from the through groove at the top of the threaded head, thereby completing the replacement of the filter bin and reducing the purpose of dismantling the device to replace the filter bin.

The scraper 402 is arranged below the rotating shaft 401, and the cleaning plate 403 is arranged on the outside of the scraper 402. The rotating shaft 401 rotates, thereby driving the cleaning plate 403 to make a circular motion around the rotating shaft 401, thereby ensuring the cleaning of the inner wall of the filter bin 3 and ensuring the filtering of the smoke by the filter bin 3. The threaded head 404 is arranged at the top of the rotating shaft 401. The threaded head 404 arranged at the top of the rotating shaft 401 ensures the disassembly and assembly of the filter bin 3.

[0034] See also Figure 2 , Figure 6 and Figure 7 A carrying mechanism 6 is arranged below the cleaning mechanism 4, and the carrying mechanism 6 includes a carrying plate 601, a sealing block 602, a retracting plate 603 and a second spring telescopic rod 604. The carrying plate 601 is arranged at the bottom of the filter bin 3.

[0035] See also Figure 3 , Figure 6 and Figure 7The scraper 402 fits tightly against the top of the carrier plate 601. The scraper 402 fits tightly against the top of the carrier plate 601, which ensures that the carrier plate 601 moves in an arc when the scraper 402 moves. The edge of the scraper 402 is set as a cut surface, and the scraper 402 is fixedly connected to the rotating shaft 401 through a limiting ring.

The tight fit between the sealing block 602 and the slide groove at the top of the carrier plate 601 ensures that when the sealing block 602 is closed, the impurities at the top of the carrier plate 601 are collected. Example 2

[0038] See also Figure 2 , Figure 3 and Figure 4, which is a second embodiment of the present invention, specifically a further description of the cleaning mechanism 4, a limiting mechanism 5 is provided at the top of the cleaning mechanism 4, and the limiting mechanism 5 includes a limiting cylinder 501, a first spring telescopic rod 502 and a sliding block 503, the limiting cylinder 501 is provided at the top of the cleaning mechanism 4, and the first spring telescopic rod 502 is provided on the inner side of the limiting cylinder 501, through the provision of the first spring telescopic rod 502, it is ensured that the threaded head 404 moves up and down on the inner wall of the limiting cylinder 501, the sliding block 503 is provided on the outer side of the first spring telescopic rod 502, and the first spring telescopic rod 502 is connected to the top slide groove of the threaded head 404 by a slide groove, through the provision of the sliding block 503, it is ensured that when the sliding block 503 rotates with the threaded head 404, the sliding block 503 rotates along the top slide groove of the threaded head 404, and the through groove at the top of the threaded head 404 ensures the limitation of the sliding block 503.

[0039] See also Figure 4 and Figure 5 The upper part of the inner wall of the limiting cylinder 501 is arranged as a smooth curved surface. The smooth curved surface arranged on the upper part of the inner wall of the limiting cylinder 501 ensures that when the thread head 404 rotates with the rotating shaft 401, the thread head 404 will not engage with the limiting cylinder 501, thereby ensuring that the rotating shaft 404 completes idling, and a thread groove is arranged at the lower part of the inner wall of the limiting cylinder 501, and the thread groove at the lower part of the inner wall of the limiting cylinder 501 and the thread head 404 are threadedly connected. The thread groove arranged at the lower part of the inner wall of the limiting cylinder 501 ensures that the thread head 404 and the thread groove at the lower part of the inner wall of the limiting cylinder 501 are threadedly connected, ensuring that when the rotating shaft 401 drives the thread head 404 to rotate, the thread head 404 moves downward, thereby ensuring the disassembly and assembly of the filter bin 3.

[0040] The working principle of the utility model is as follows: when it is necessary to filter the smoke inside the incinerator, the smoke is first transported to the inside of the filter chamber 3 through the smoke inlet 2, and then the smoke is transported out of the device from the filter chamber 3 through the smoke outlet 7. When the smoke is inside the filter chamber 3, the smoke is filtered by the filter chamber 3, thereby completing the filtration of the smoke;

[0041] Furthermore, when the smoke is filtered inside the filter bin 3, due to the long-term use of the filter bin 3, more dust is attached to the inner wall of the filter bin 3, and the ventilation effect of the filter bin 3 is affected. When the smoke is filtered, the operator rotates the handle at the bottom of the rotating shaft 401 to rotate the rotating shaft 401. When the rotating shaft 401 rotates, the cleaning plate 403 moves in a circle with the rotating shaft 401. The cleaning plate 403 is closely attached to the inner wall of the filter bin 3, and the edge of the cleaning plate 403 is a cut surface, so that the dust attached to the inner wall of the filter bin 3 is scraped off, and the dust scraped off from the inner wall of the filter bin 3 falls to the top of the carrying plate 601, thereby completing the cleaning of the inner wall of the filter bin 3 and improving the service life of the filter bin 3.

[0042] Furthermore, when there is a lot of dust left on the top of the supporting plate 601 and the filter bin 3 needs to be replaced, the operator pulls down the handle at the bottom of the rotating shaft 401 and rotates the rotating shaft 401 at the same time. At this time, the scraper 402 at the bottom of the rotating shaft 401 contacts the bottom of the supporting plate 601, thereby completing the cleaning of the top of the supporting plate 601. At this time, the scraper 402 is tightly fitted with the sealing block 602, and the second spring telescopic rod 604 is subjected to the pressure of the sealing block 602 on the retracting plate 603, so that the second spring telescopic rod 604 is retracted. At this time, the sealing block 602 moves along the top slide groove of the supporting plate 601, so that the through groove of the supporting plate 601 is opened. At this time, the dust on the top of the supporting plate 601 falls from the through groove at the top of the supporting plate 601, and the rotating shaft is pulled downward at the same time. 401, at this time, the first spring telescopic rod 502 is stretched downward by the engagement connection between the sliding block 503 and the threaded head 404. At this time, the threaded head 404 is meshed with the thread below the inner wall of the limiting cylinder 501. The rotating shaft 401 is continuously rotated, so that the threaded head 404 drives the rotating shaft 401 to move downward, thereby causing the supporting mechanism 6 and the filter bin 3 to move downward at the same time. When the threaded head 404 moves to the end of the limiting cylinder 501, the sliding block 503 and the threaded head 404 are in a tensioned state. The rotating shaft 401 is continuously rotated to drive the threaded head 404 to rotate, thereby causing the sliding block 503 to detach from the threaded head 404 from the through groove at the top of the threaded head 404, thereby completing the replacement of the filter bin 3 and reducing the purpose of dismantling the device to replace the filter bin 3.
