The cleaning assembly further comprises: a fan 22, the fan 22 is fixedly installed on the inner wall of the installation groove 21, a sealing plate 23 is arranged in the communication two 20 through a sealing piece, a filter screen two 24 is fixedly installed on the rear side wall of the sealing plate 23, and the cleaning assembly further comprises a driving piece.

[0036] As a preferred embodiment in this embodiment, please refer to Figure 6 And Figure 8As shown, the sealing member comprises: a moving block 25 arranged on the bottom surface of the sealing plate 23, the bottom surface of the installation groove 21 is provided with a moving groove 26, a limiting rod one 27 is fixedly installed in the moving groove 26, the moving block 25 is sleeved on the outer surface of the limiting rod one 27 and slides in the moving groove 26, the front side wall of the moving block 25 is fixedly installed with a spring one 28, the side wall of the limiting rod one 27 is fixedly installed with an electromagnet 29, and the bottom surface of the communication two 20 is provided with a connecting groove 30 which is communicated with the inside of the collecting box 17.

[0038] Through the above features, when the power of the compressor body 2 is too fast, the carbon dioxide is branched, and the flue gas particles in the filter box 3 can be collected. Specifically, when the power of the compressor body 2 is too fast, the flow rate of the carbon dioxide will also be too fast, causing the inclined plate 10 to move to the right. In this process, the sliding block 31 connected with the inclined plate 10 moves synchronously, and the sliding block 31 will contact the micro switch 33, causing the fan 22 to start, causing negative pressure in the inside of the branching box 16, and in the process of moving the inclined plate 10, the pressing rod 35 rotates, causing the sealing plate 23 to be pushed open to the inside of the installation groove 21. At this time, part of the carbon dioxide will enter the installation groove 21 through the communication groove one 19 and the communication two 20, and then enter the inside of the compressor body 2 through the connecting pipe two 18 and the gas outlet pipe 4;

[0039] When it is necessary to clean the flue gas particles in the filter box 3, the staff first stops the work of the compressor body 2 through the controller, and makes the electromagnet 29 electrified, so that the electromagnet 29 adsorbs the moving block 25. In the process of moving the moving block 25, the spring one 28 is compressed, deformed, and causes the sealing plate 23 to move synchronously with the filter screen two 24. Then the fan 22 is started and stopped intermittently. At this time, the filter box 3 is blocked by the filter screen two 24 on the side wall of the sealing plate 23 when the flue gas particles pass through the communication groove one 19 and the communication two 20. When the fan 22 stops, the flue gas shell falls into the collecting box 17 through the connecting groove 30 for collection. When the electromagnet 29 is deenergized, the spring one 28 returns to its original position.

[0040] It is worth mentioning that the return of the pressing rod 35 to the original position is also caused by the return force of the spring one 28.

[0041] As a preferred embodiment in the present embodiment, please refer to Figure 9 As shown in the drawings, the sliding member comprises a sliding block 14 fixedly installed on the bottom surface of the inclined plate 10, the bottom surface of the filter compartment 7 is provided with a sliding groove 15, the sliding groove 15 is fixedly provided with a limiting rod two 37, and the sidewall of the sliding block 14 and the sidewall of the sliding groove 15 are provided with a spring two 38.

[0042] Through the above features, the inclined plate 10 can move. Specifically, when the carbon dioxide blows on the left sidewall of the inclined plate 10, the sliding block 14 moves, and at the same time, the sliding block 14 pressurizes the limiting rod two 37 and moves the inclined plate 10. At this time, the top surface of the inclined plate 10 no longer contacts the bottom surface of the cover plate 8, but moves in the flow guide groove 9, so that the carbon dioxide enters the next step through the flow guide groove 9.

[0043] As a preferred embodiment in the present embodiment, please refer to Figure 4 and Figure 6 As shown in the drawings, the sidewall of the inclined plate 10, the baffle 11 and the sealing plate 23 are provided with activated carbon plates. Through the above features, the acidic gas can be filtered to avoid corroding the inside of the compressor body 2.

[0044] Working principle:

[0045] In use, first, the compressor body 2 is started, and the carbon dioxide gas to be treated enters the filter compartment 7 of the filter box 3 through the air inlet pipe 6; when the gas impacts the inclined plate 10, the baffle 13 on the left sidewall thereof preliminarily intercepts the flue gas particles, and at the same time, the activated carbon plate on the inclined plate 10 adsorbs the acidic impurities; then the gas flows along the flow guide groove 9, is secondarily filtered by the activated carbon plate on the baffle 11, and is fine filtered by the filter screen one 12, and then the clean carbon dioxide enters the compressor body 2 through the air outlet pipe 4, is compressed, and is sent into the condensation separation tank 36 through the connecting pipe one 5; when the compressor power suddenly increases and the airflow speed increases, the inclined plate 10 moves right under the cooperation of the sliding block 14 and the spring two 38, the sliding block 31 triggers the micro switch 33 to start the fan 22, the extrusion rod 35 rotates around the rotating column 34 to open the sealing plate 23, so that part of the gas enters the shunt box 16 through the communication groove one 19 and the communication two 20, and then is collected into the air outlet pipe 4 through the connecting pipe two 18, so as to realize dynamic shunting and pressure stabilization; when cleaning is needed, the system is stopped and the electromagnet 29 is energized, the moving block 25 compresses the spring one 28 to drive the sealing plate 23 to open, and the fan 22 is intermittently operated to suck the particles in the filter compartment 7 into the collection box 17 through the connecting groove 30. After power-off, the spring one 28 is reset, the sealing plate 23 is closed, the system returns to standby state, and automatic cleaning is completed.

[0046] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
