[0034] The inner diameter of the semicircular groove 48 is matched with the diameter of the end of the latch pin 51 , so as to ensure that the end of the latch pin 51 can be inserted into the inner cavity of the semicircular groove 48 .

[0035] In summary, when the waste heat energy storage device for the domestic waste incineration boiler is used, the domestic waste is first put into the inner cavity of the incinerator 1 for incineration, and the exhaust fan 6 is started to draw the flue gas generated by the incineration of the domestic waste in the incinerator 1 into the inner cavity of the filter chamber 26, and the dust in the flue gas is filtered by the right filter 30, and the filtered flue gas is introduced from the main air pipe 14 into the main heat exchange copper tube 17, and the heat of the flue gas in the inner cavity of the main heat exchange copper tube 17 is exchanged with the water in the inner cavity of the main heat exchange tank 2, so as to heat the main heat exchange copper tube 17. The water in the inner cavity of the heat tank 2 is heated, and then the flue gas in the inner cavity of the main heat exchange copper tube 17 is introduced into the auxiliary heat exchange copper tube 18 through the auxiliary air guide pipe 52. The residual heat of the flue gas in the inner cavity of the auxiliary heat exchange copper tube 18 is used to exchange heat with the water in the inner cavity of the auxiliary heat exchange tank 3, and the water in the inner cavity of the auxiliary heat exchange tank 3 is preheated. Then, the flue gas in the inner cavity of the auxiliary heat exchange copper tube 18 is introduced into the inner cavity of the filter cartridge 13 through the connecting pipe 22, and the odor in the flue gas is adsorbed by the activated carbon block 21, and finally the flue gas is discharged from the exhaust pipe 23;

[0036] When the flue gas in the inner cavity of the main heat exchange copper tube 17 exchanges heat with the water in the inner cavity of the main heat exchange tank 2 to heat the water in the inner cavity of the main heat exchange tank 2, the temperature sensor 53 continuously detects the temperature of the water in the inner cavity of the main heat exchange tank 2.

[0037] When the right filter 30 filters the smoke, the servo motor 24 rotates continuously, and the transmission between the first sprocket 40 and the first chain 41 drives the two right rotating shafts 39 to rotate, thereby driving the two right cleaning rollers 45 to rotate. In addition, the transmission between the second sprocket 43 and the second chain 44 drives the two left rotating shafts 42 to rotate, thereby driving the two left cleaning rollers 46 to rotate, and the left cleaning roller 46 is used to clean the dust on the left filter 33. At this time, one side of the right filter frame 29 is against the inner wall of the filter chamber 26, so that the right pull column 32, the right connecting block 35, and the second rack 38 cannot move, so that the spur gear 25 cannot rotate. After the right filter 30 has filtered for a fixed time, the servo motor 24 is controlled to rotate in the opposite direction. At this time, the end of the pin 51 is inserted into the inner cavity of the semicircular groove 48 under the elastic force of the spring 50 to drive the spur gear 25 to rotate, and the meshing transmission of the spur gear 25 and the first rack 37 and the second rack 38 is used to drive the second rack 38 and the first rack 37 and the second rack 38. The first rack 37 moves in the same direction, thereby driving the right filter frame 29 and the right filter screen 30 to move to the inner cavity of the right ash collection chamber 28. At this time, the rotating right cleaning roller 45 cleans the dust on the right filter screen 30. In addition, the left filter frame 31 and the left filter screen 33 move to the inner cavity of the filter chamber 26 under the push of the left pull column 34, and the dust in the smoke is filtered by the left filter screen 33. When one side of the left filter frame 31 abuts against the inner wall of the filter chamber 26, the first rack 37 and the second rack The strip 38 can no longer move, the end of the latch 51 disengages from the inner cavity of the semicircular groove 48 and retracts into the inner cavity of the compression groove 49, and the spur gear 25 stops rotating. When the left filter screen 33 has filtered for a fixed period of time, the servo motor 24 is rotated in the opposite direction again, so that the right filter screen 30 moves to the inner cavity of the filter chamber 26 to filter the dust in the flue gas, and the left filter screen 33 is moved to the inner cavity of the left ash collecting chamber 27 and the dust on its surface is cleaned by the left cleaning roller 46, and this process is repeated.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
