Description

Technical Field

[0001] The present invention relates to the technical field of waste pyrolysis, and specifically to a domestic waste pyrolysis device. Background Art

[0002] Domestic waste pyrolysis is a waste treatment technology that utilizes the thermal instability of organic matter in domestic waste to heat it under anaerobic or anoxic conditions, causing the organic matter to crack and generate a series of combustible gas, liquid, and solid products. The domestic waste pyrolysis process is mainly divided into three stages: drying, pyrolysis, and gasification. The gas products mainly include combustible gases such as hydrogen, methane, and carbon monoxide, and the liquid products are mainly tar, which is a viscous dark liquid.

[0003] When the pyrolysis furnace pyrolyzes domestic waste, after the flue gas generated by pyrolysis is heat-exchanged, it is usually directly discharged to the outside. There is still a certain amount of heat in the flue gas, and directly discharging it will cause waste of energy. Moreover, the collection of pyrolysis products is relatively troublesome, and the pyrolysis products cannot be collected in time. After a long time, the pyrolysis products may melt into slag. Summary of the Invention

[0004] The purpose of the present invention is to provide a domestic waste pyrolysis device to solve the problem of inconvenient use of existing pyrolysis devices.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

The rotating ring 13 drives the fixed cylinder 8 and the collection pipe 9 to rotate. The smoke pipe 5 introduces the flue gas into the pyrolysis furnace 1 by cooperating with the air inlet pipe 4. The fixed cylinder 8 drives the collection pipe 9 to slide by cooperating with the guide groove 601. The pyrolysis products enter the collection box 6 along the collection plate 31.

[0038] As Figures 1-4 shown, as a preferred embodiment of the present invention, the rotating mechanism includes a support frame 17 arranged on the back of the pyrolysis furnace 1, and a motor 20 arranged on the support frame 17. A driving rod 19 is arranged at the rotating end of the motor 20. A gear 18 is arranged outside the driving rod 19. A plurality of gear grooves 131 meshing with the gear 18 are formed outside the rotating ring 13. The motor 20 drives the gear 18 to rotate through the driving rod 19, and the gear 18 drives the rotating ring 13 to rotate.

[0039] As Figures 1-6 shown, as a preferred embodiment of the present invention, a sealing plate 35 is rotatably arranged on the partition plate 27. A connecting spring 36 is arranged on the side wall of the sealing plate 35. One end of the connecting spring 36 is connected to the inner wall of the pyrolysis furnace 1. A feed hopper 23 is arranged above the sealing plate 35. The feed hopper 23 is arranged on the outer side wall of the pyrolysis furnace 1. Domestic waste is put into the pyrolysis furnace 1 from the feed hopper 23, and the sealing plate 35 flips downward so that the domestic waste falls to the bottom of the pyrolysis furnace 1.

[0040] As Figure 6 shown, as a preferred embodiment of the present invention, a plurality of support plates 24 are arranged on the side wall of the heat exchange cylinder 7. A filter layer 241 is arranged on the support plates 24, which can filter harmful substances in the flue gas.

[0041] As Figure 3As shown, as a preferred embodiment of the present invention, a fixing block 15 is provided outside the collection box 6. A limit pin 16 is vertically provided on the fixing block 15. A spring 161 is sleeved outside the limit pin 16, and the collection box 14 is limited by the limit pin 16.

[0042] As Figures 7-10 As shown, as a preferred embodiment of the present invention, a rotating shaft 321 is provided outside the baffle 32. The baffle 32 is rotatably arranged inside the installation groove 801 through the rotating shaft 321. Extrusion grooves 37 are formed on one side of the air outlet plate 30 and the collection plate 31 close to the collection pipe 9. The collection pipe 9 slides along the inner wall of the fixed cylinder 8 and squeezes the air outlet plate 30 and the collection plate 31 through the extrusion groove 37.

[0043] As Figure 1 As shown, as a preferred embodiment of the present invention, a protective plate 2 is provided outside the pyrolysis furnace 1. An exhaust pipe 38 is provided on the top of the collection box 6. The exhaust pipe 38 is connected with a purification device, which can purify and absorb the discharged tail gas.

[0044] As Figure 11 As shown, as a preferred embodiment of the present invention, domestic waste is put into the placement groove 281 for pyrolysis. When the fixed cylinder 8 moves to the bottom of the placement groove 281, in order to prevent the waste from entering the inside of the collection plate 31 and blocking the collection plate 31, a filter screen 311 can be installed at the opening position outside the collection plate 31. The products formed by pyrolysis enter the collection plate 31 through the filter screen 311.

[0045] In the above embodiment of the present invention, a domestic waste pyrolysis device is provided. The domestic waste to be pyrolyzed is input from the feed hopper 23. The domestic waste is pyrolyzed inside the placement groove 281. The motor 20 drives the gear 18 to rotate through the driving rod 19. The gear 18 drives the rotating ring 13 to rotate. The rotating ring 13 drives a plurality of fixed cylinders 8 to rotate, which can turn the domestic waste, improve the heating efficiency, and prevent the domestic waste from being squeezed against each other, affecting the normal progress of pyrolysis; The rotating ring 13 drives a plurality of fixed cylinders 8 and the collection pipe 9 to rotate. When the fixed cylinder 8 moves to the lowest position of the guide groove 601 (i.e., Figure 2 position B), the collection pipe 9 penetrates into the fixed cylinder 8 and squeezes the air outlet plate 30 and the collection plate 31 away from each other, that is, Figures 7-8The position shown. At this time, the flue gas generated by pyrolysis is filtered and enters the interior of the intake box 3 through the flue gas pipe 5 and the intake pipe 4. The flue gas sequentially passes through the intake hood 22 and the fixed cylinder 8 and is discharged from the side wall of the air outlet plate 30, which can preheat and dry the domestic waste inside the pyrolysis furnace 1, making the interior of the pyrolysis furnace 1 in an oxygen-deficient environment to ensure the normal progress of waste pyrolysis. The collection plate 31 collects the pyrolysis products through the grooves provided on the side wall. The collection pipe 9 holds the baffle 32 through the card slot 901, making the baffle 32 in a vertical position, which can seal the contact position between the collection plate 31 and the fixed cylinder 8 to prevent the pyrolysis products from entering the fixed cylinder 8. When the fixed cylinder 8 moves to the uppermost position of the guide groove 601 (i.e., Figure 2 position A), at this time, the collection pipe 9 penetrates outwards along the fixed cylinder 8, and the air outlet plate 30 and the collection plate 31 slide into the interior of the fixed cylinder 8, that is, Figures 9-10 the position shown. At this time, the flue gas cannot be discharged from the side wall of the movable plate 30. The collection pipe 9 is separated from the baffle 32, and the pyrolysis products in the collection plate 31 fall into the fixed cylinder 8. The flue gas pushes the pyrolysis products outwards, and the pyrolysis products pass through the collection pipe 9 and the ball head 10 and fall into the interior of the collection box 14, realizing the synchronous collection of the pyrolysis products and preventing the pyrolysis products from melting into slag after being squeezed for a long time.

[0046] As described above, only the specific implementation manners of the present disclosure are provided, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
