Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a low-concentration gas thermal storage oxidation device, including a mounting plate 1 and support columns 2 fixedly installed around the bottom of the mounting plate 1, a processing box 3 is fixedly connected to one side of the top of the mounting plate 1, and an oxidation tank 7 is fixedly installed on the other side of the top of the mounting plate 1.

[0031] A gas inlet 4 is connected to the middle of one side of the processing box 3, an air inlet 5 is connected to the lower part of one side of the processing box 3, a connecting pipe 6 is installed between the processing box 3 and the oxidation tank 7, and an observation window 8 is connected to the front side of the oxidation tank 7.

[0032] A driving motor 9 is fixedly installed on the upper part of one side of the processing box 3, and the output end of the driving motor 9 passes through the processing box 3 and is fixedly connected to a rotating shaft 10. One end of the rotating shaft 10 is fixedly connected to a cam 11. The rotating shaft 10 is symmetrically arranged up and down. The lower rotating shaft 10 is rotatably connected to the mounting plate 1, and a pulley 12 is fixedly connected to the outer middle part of the rotating shaft 10. The two pulleys 12 are connected by belt adapters.

[0033] Among them, the upper and lower cams 11 are symmetrically arranged, a fixed plate 13 is fixedly connected to the middle part of one side of the processing box 3, and a return spring 15 is symmetrically fixed to the top and bottom of the fixed plate 13, and one end of the return spring 15 is connected to an abutment block 14, and the abutment block 14 abuts against the cam 11. The inner top surface and the inner bottom surface of the processing box 3 are symmetrically connected with a sliding rod 16, and the outer side of the sliding rod 16 is slidably connected with a scraping plate 17. A connecting rod 19 is fixedly connected to one side of the abutment block 14, and a filter screen 21 is installed inside the processing box 3.

[0034] The scraping plate 17 is fixedly connected to the connecting rod 19 , and a cleaning brush 18 is fixedly connected to one side of the scraping plate 17 , and the cleaning brush 18 is in contact with the filter screen 21 .

[0035] When the device is in use, low-concentration gas enters from the gas inlet 4, and air enters from the air inlet 5. After passing through the through hole 22 on the scraper plate 17, it is filtered by the filter screen 21 and mixed, and then input into the oxidation tank 7 through the connecting pipe 6 for internal oxidation. At the same time, the drive motor 9 is started to rotate slowly, and the drive motor 9 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the cam 11 to rotate. Through the cooperation of the pulley 12 and the belt, the rotating shaft 10 and the cam 11 at the bottom can be driven to rotate synchronously.

[0036] Since the upper and lower cams 11 are symmetrically arranged, the tips of the two cams 11 will squeeze the abutment block 14 at the same time or move away from the abutment block 14 at the same time. When the tip of the cam 11 squeezes the abutment block 14, the return spring 15 is forced to contract.

If it is not cleaned in time, it will cause clogging of the filter hole, hindering the subsequent air and low-concentration gas from entering, and reducing the filtering effect of the device.

[0037] The inner top surface and the inner bottom surface of the processing box 3 are symmetrically fixed with the limiting plates 20 . The filter screen 21 is located between the two limiting plates 20 , and the filter screen 21 is slidably connected to the limiting plates 20 .

[0038] One end of the return spring 15 away from the fixed plate 13 is fixedly connected to the abutment block 14 , the slide rod 16 is fixedly connected to the processing box 3 , and through holes 22 are evenly opened inside the scraping plate 17 .

[0039] A cover plate 24 is hinged on one side of the front of the processing box 3, and a locking plate 25 is fixedly connected to the top of the cover plate 24. A positioning block 27 is fixedly connected to the top of the processing box 3. The locking plate 25 is L-shaped, and a latch 26 is slidably connected to one side of the locking plate 25.

[0040] A compression spring is slidably connected to the outer side of the upper portion of the latch 26 , the top end of the compression spring is fixedly connected to the latch 26 , and the bottom end of the compression spring is fixedly connected to the clamping plate 25 .

[0041] When the internal filter 21 needs to be replaced, the latch 26 is pulled up, and the latch 26 drives the compression spring thereon to stretch, so that the latch 26 is disengaged from the inside of the slot 28, and then the cover 24 is flipped outward to open, and the filter 21 is pulled out from the inner side of the limit plate 20, so that the filter 21 can be easily taken out and replaced and cleaned, and the scraper plate 17 and the cleaning brush 18 are cleaned with a cleaning brush for subsequent use.

[0042] A guide plate 23 is fixedly connected to the inside of the processing box 3. The guide plate 23 is located on the side of the filter 21 close to the connecting pipe 6. The guide plate 23 is bent. The fold line of the guide plate 23 facilitates the full mixing of the low-concentration gas inside with the air, which is convenient for the subsequent thermal storage oxidation operation.

[0043] Working principle:

[0044] Before using this low-concentration gas thermal storage oxidation device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6 As shown, when the device is in use, low-concentration gas enters from the gas inlet 4, and air enters from the air inlet 5. After passing through the through hole 22 on the scraper plate 17, it is filtered by the filter screen 21 and mixed, and then input into the oxidation tank 7 through the connecting pipe 6 for internal oxidation. The fold line setting of the guide plate 23 facilitates the full mixing of the low-concentration gas and air inside, which is convenient for the subsequent thermal storage oxidation operation.

[0045] At the same time, the drive motor 9 is started to rotate slowly. The drive motor 9 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the cam 11 to rotate. Through the cooperation of the pulley 12 and the belt, the rotating shaft 10 and the cam 11 at the bottom can be driven to rotate synchronously. Since the upper and lower cams 11 are symmetrically arranged, the tips of the two cams 11 will squeeze the abutment block 14 at the same time or move away from the abutment block 14 at the same time. When the tip of the cam 11 squeezes the abutment block 14, the reset spring 15 is forced to shrink. When the tip of the cam 11 moves away from the abutment block 14, the elastic force of the reset spring 15 drives the abutment block 14 to reset. The abutment block 14 then drives the scraper plate 17 to move through the connecting rod 19, so that the scraper plate 17 drives the cleaning brush 18 to move up and down, which is convenient for the cleaning brush 18 to clean the surface of the filter screen 21.

[0046] When the internal filter 21 needs to be replaced, the latch 26 is pulled up, and the latch 26 drives the compression spring thereon to stretch, so that the latch 26 is disengaged from the inside of the slot 28, and then the cover 24 is flipped outward to open, and the filter 21 is pulled out from the inner side of the limit plate 20, so that the filter 21 can be easily taken out and replaced and cleaned, and the scraper plate 17 and the cleaning brush 18 are cleaned with a cleaning brush for subsequent use.
