[0014] The present invention provides an environment-friendly domestic waste pyrolysis furnace. It has the following beneficial effects:

[0015] (1) In this invention, the rotation of the rotating rod drives the rotation of the spiral blade, and the rotation of the spiral blade drives the domestic waste to be conveyed into the pyrolysis furnace body for pyrolysis, which can achieve continuous conveying and improve work efficiency. The reciprocating movement of the circular plate will push the garbage towards the spiral blade, preventing the garbage from containing large objects that may cause blockage of the screw conveyor and affecting the normal operation of the equipment.

[0016] (2) In this invention, the rotation of the fan blades expels the waste gas generated by incineration, which helps reduce the concentration of pollutants inside the pyrolysis furnace body and ensures the normal progress of the incineration process. At the same time, the rotation of the filter plate can evenly distribute the deposition of pollutants and reduce local accumulation, thereby extending the service life of the filter plate. The scraping frame will scrape off the impurities accumulated at the bottom of the filter plate to prevent a large amount of dust in the waste gas from clogging the filter plate and affecting its filtering effect.

[0017] (3) In this invention, the rotation of the circular plate drives the rotation of the arc-shaped paddles. The arc-shaped paddles are used to level the conveyed garbage, preventing the garbage from piling up at the inlet of the feed pipe and blocking the subsequent garbage, which affects the garbage conveyance. The roller reset knocks on the circular plate, and when the circular plate vibrates due to the knocking, the garbage adhering to the circular plate and the arc-shaped paddles shakes off, preventing the garbage from adhering to the bottom of the circular plate and the arc-shaped paddles and causing the equipment to be entangled, which affects the normal use of the equipment.

[0018] (4) In this invention, when the sealing plate moves downward, it squeezes the air to enter from the T-shaped pipe on the side close to the heat conduction plate. By using the oxygen contained in the air, it can increase the combustion temperature and rate of the incinerated garbage, accelerate the garbage combustion process, and improve the combustion efficiency. At the same time, when the air enters the pyrolysis furnace body from the T-shaped pipe on the side close to the heat conduction plate, it drives the fan to rotate. The rotation of the fan can make the air more evenly distributed inside the pyrolysis furnace body and improve the overall combustion efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The semi-circular block 14 is in contact with the surface of the reciprocating thread groove, the threaded block 9 slides in the reciprocating thread groove, and the fixed rod 12 penetrates through the surface of the circular plate 10.

[0032] The filtering device includes a driving device 151, a fan blade 152, a connecting rod 153 and a filter plate 154, which helps to reduce the pollutant concentration inside the pyrolysis furnace body 1 and ensure the normal progress of the incineration process. The driving device 151 is fixedly installed at the top inner wall of the air outlet pipe 5. The fan blade 152 is fixedly installed at the output end of the driving device 151. The connecting rod 153 is fixedly installed at the bottom of the output end of the driving device 151. The filter plate 154 is fixedly installed at the bottom of the connecting rod 153. The rotation of the filter plate 154 can evenly distribute the deposition of pollutants and reduce the local accumulation, thereby prolonging the service life of the filter plate 154.

[0033] A scraping frame 155 is fixedly installed at the bottom of the air outlet pipe 5. A collection box 156 is fixedly installed at the bottom of the scraping frame 155. A triangular block 157 is fixedly installed at the top of the scraping frame 155. The top of the scraping frame 155 is in contact with the surface of the filter plate 154. The dust is recycled to prevent the dust from spreading in the air, causing the deterioration of air quality and affecting the lives of nearby people.

[0034] When this embodiment works, the rotation of the motor 4 drives the rotation of the rotating rod 7. The rotation of the rotating rod 7 drives the rotation of the spiral blade 8. The rotation of the spiral blade 8 drives the domestic waste to be conveyed into the pyrolysis furnace body 1 for pyrolysis. At the same time, the rotation of the rotating rod 7 will drive the reciprocating movement of the threaded block 9. The reciprocating movement of the threaded block 9 will drive the reciprocating movement of the circular plate 10. The reciprocating movement of the circular plate 10 will push the garbage towards the spiral blade 8 to prevent the garbage from containing large objects, which may cause the blockage of the screw conveyor and affect the normal operation of the equipment.

During the reciprocating movement of the arc plate 11, the feeding port 6 will be continuously opened and closed to prevent continuous feeding from causing equipment overload and affecting the normal conveyance of domestic waste by the equipment. At the same time, when the threaded block 9 reciprocates, it will drive the reciprocating movement of the L-shaped rod 13. The reciprocating movement of the L-shaped rod 13 will drive the reciprocating movement of the semi-circular block 14. The reciprocating movement of the semi-circular block 14 will clean the reciprocating thread groove to prevent impurities from getting stuck in the reciprocating thread groove, resulting in the abnormal movement of the threaded block 9 and affecting the pushing effect of the circular plate 10.

[0035] The driving device 151 rotates to drive the fan blade 152 to rotate. The rotation of the fan blade 152 is used to discharge the waste gas generated by incineration, which helps to reduce the pollutant concentration inside the pyrolysis furnace body 1 and ensure the normal progress of the incineration process. At the same time, the filter plate 154 can effectively filter the harmful gases in the waste gas, prevent the harmful gases from causing environmental pollution and affecting the ecological balance. At the same time, the rotation of the filter plate 154 can evenly distribute the deposition of pollutants and reduce the situation of local accumulation, thereby extending the service life of the filter plate 154. At the same time, when the filter plate 154 rotates, it will contact the scraping frame 155, and the scraping frame 155 will scrape off the impurities accumulated at the bottom of the filter plate 154, preventing a large amount of dust in the waste gas from blocking the filter plate 154 and affecting the filtering effect of the filter plate 154. At the same time, the scraped dust will enter the collection box 156 along the triangular block 157, and the dust is recycled to prevent the dust from spreading in the air and causing the air quality to deteriorate and affecting the lives of nearby people.

[0036] Please refer to Figures 1-9 , on the basis of the above embodiment, in another embodiment of the present invention, an anti-accumulation device for preventing garbage accumulation is provided at the bottom of the filtering device, and a heating device for improving incineration is provided on the inner wall of the pyrolysis furnace body 1. The anti-accumulation device includes a long rod 161, a circular plate 162 and an arc-shaped dial 163, which prevent garbage from accumulating at the inlet of the feeding pipe 2, resulting in subsequent garbage being blocked and affecting garbage transportation. The long rod 161 is fixedly installed at the bottom of the filter plate 154, the circular plate 162 is fixedly installed at the bottom of the long rod 161, and the arc-shaped dial 163 is fixedly installed at the bottom of the circular plate 162.

[0037] A connecting seat 164 is fixedly installed on the inner wall of the pyrolysis furnace body 1. The connecting seat 164 is rotatably installed with a rotating plate 165 through a rotating shaft. A roller 166 is fixedly installed on the surface of the rotating plate 165. A triangular plate 167 is fixedly installed on the top of the circular plate 162. A first torsion spring is provided between the connecting seat 164 and the rotating plate 165 to prevent garbage from adhering to the bottom of the circular plate 162 and the arc-shaped dial 163, resulting in the equipment being entangled and affecting the normal use of the equipment. The rotating plate 165 is driven to reset by the first torsion spring.

[0038] The heating device includes a heat conduction plate 171, a hollow box 172, an electric telescopic rod 173, a T-shaped pipe 174, and a sealing plate 175. The heat conduction plate 171 is fixedly installed on the inner wall of the pyrolysis furnace body 1, the hollow box 172 is fixedly installed on the surface of the pyrolysis furnace body 1, the electric telescopic rod 173 is fixedly installed on the top of the inner wall of the hollow box 172, the T-shaped pipe 174 is fixedly installed on the inner wall of the hollow box 172, the sealing plate 175 is fixedly installed at the output end of the electric telescopic rod 173, the sealing plate 175 fits with the inner wall of the T-shaped pipe 174, and a one-way valve is arranged on the side of the T-shaped pipe 174 away from the pyrolysis furnace body 1. By using the oxygen contained in the air, the combustion temperature and rate of burning garbage can be increased, the burning process of garbage can be accelerated, and the combustion efficiency can be improved. The one-way valve is used to prevent gas from leaking from the side away from the pyrolysis furnace body 1.

[0039] A support frame 176 is fixedly installed on the inner wall of the T-shaped pipe 174, and a fan 177 is rotatably installed on the surface of the support frame 176. By rotating the fan 177, the air can be more evenly distributed inside the pyrolysis furnace body 1, and the overall combustion efficiency can be improved.

[0040] When this embodiment works, the rotation of the filter plate 154 drives the rotation of the long rod 161, the rotation of the long rod 161 drives the rotation of the circular plate 162, and the rotation of the circular plate 162 drives the rotation of the arc-shaped dial 163. The arc-shaped dial 163 is used to push the incoming garbage flat, preventing the garbage from piling up at the entrance of the feeding pipe 2, which may block the subsequent garbage and affect the garbage transportation. At the same time, the piled-up garbage will affect the subsequent pyrolysis effect, resulting in a reduction in the heating surface and affecting the pyrolysis efficiency. At the same time, when the circular plate 162 rotates, it will drive the rotation of the triangular plate 167. The rotation of the triangular plate 167 will contact the roller 166, and the rotation of the triangular plate 167 will push the roller 166 to rotate upward. The upward rotation of the roller 166 will drive the upward rotation of the rotating plate 165. When the triangular plate 167 separates from the roller 166, the first torsion spring will drive the rotating plate 165 to reset, and the reset of the rotating plate 165 will drive the roller 166 to reset. By using the reset of the roller 166 to strike the circular plate 162, when vibrations are generated by striking the circular plate 162, the garbage adhering to the circular plate 162 and the arc-shaped dial 163 will fall off, preventing the garbage from adhering to the bottom of the circular plate 162 and the arc-shaped dial 163, which may entangle the equipment and affect the normal use of the equipment.

[0041] By starting the electric telescopic rod 173, when the electric telescopic rod 173 begins to contract, it will drive the sealing plate 175 to move upward. The upward movement of the sealing plate 175 will suck the external air into the T-shaped tube 174. Then, by driving the sealing plate 175 to move downward through the downward movement of the electric telescopic rod 173, the downward movement of the sealing plate 175 will squeeze the air to enter from the T-shaped tube 174 on the side close to the heat conducting plate 171. By utilizing the oxygen contained in the air, the combustion temperature and rate of the incinerated garbage can be increased, the combustion process of the garbage can be accelerated, and the combustion efficiency can be improved. At the same time, when the air enters the pyrolysis furnace body 1 from the T-shaped tube 174 on the side close to the heat conducting plate 171, it will drive the fan 177 to rotate. By utilizing the rotation of the fan 177, the air distribution in the pyrolysis furnace body 1 can be made more uniform, and the overall combustion efficiency can be improved.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
