[0024] The scraper assembly includes a primary scraper rake 9, a secondary scraper rake 26 and a tertiary scraper rake 27. The primary scraper rake 9, the secondary scraper rake 26 and the tertiary scraper rake 27 are all arranged on the carrier plate.

[0025] With respect to this specific embodiment, when it is used, the material to be incinerated enters the frame 3 through the feed port 21. At this time, the power component drives the central rotating tube 6 and the hollow tube 7 to rotate. The rotation of the hollow tube 7 drives the spiral blade 10 to rotate. The spiral blade 10 can facilitate the feeding of materials into the furnace body 1. After the materials enter the furnace body 1, they fall onto the loading plate 8. At this time, the materials on the loading plate fall to the bottom through the discharge port 22 under the rotation of the stirring component and are burned. The hollow tube 7 drives the stirring unit to rotate the loading plate. The materials on the furnace body 1 are stirred and scraped off to avoid accumulation on the loading plate. Due to the rotation of the loading plate, part of the materials will fall onto the inner wall of the furnace body 1. At this time, the rotation of the loading plate will drive the first-stage scraper rake 9, the second-stage scraper rake 26 and the third-stage scraper rake 27 to rotate to scrape the materials on the inner wall of the furnace body 1 to prevent the materials from being retained on the conical surface of the furnace body 1 and affecting the movement of the materials. The smoke generated by the combustion is discharged through the smoke exhaust port 20. In this way, the technical problems that the existing pushing device in the prior art has a poor pushing effect and the materials are easy to accumulate and affect the incineration effect are solved.

[0026] Furthermore, the spiral blade 10 is in an inverted cone shape, and the primary scraper rake 9, the secondary scraper rake 26 and the tertiary scraper rake 27 are divided into two shapes: a rake with an angle and a rake with an inclination.

[0027] With respect to this specific embodiment, the above arrangement facilitates the downward transportation of the material retained on the conical surface of the furnace body 1, and the material movement trajectory is in a partial spiral state, further enhancing the dynamic movement time of the material during transportation, which is beneficial to material drying.

[0028] Furthermore, the stirring assembly includes an arc-shaped stirring paddle 11 and an eccentric stirring slurry scraper 12, the arc-shaped stirring paddle 11 is fixedly connected to the hollow tube 7, the eccentric stirring slurry scraper 12 is also fixedly connected to the hollow tube 7, and the eccentric stirring slurry scraper 12 and the arc-shaped stirring paddle 11 are both located above the loading plate 8.

[0029] According to the present specific embodiment, the hollow tube 7 drives the arc-shaped stirring paddle 11 and the eccentric stirring slurry scraper 12 to rotate to disperse the material on the carrier plate 8 and scrape it to the bottom of the carrier plate 8 .

[0030] Furthermore, the power assembly includes a mounting frame 13, a motor 14 and a bevel gear transmission unit 15, the motor 14 is mounted on the frame 3 through the mounting frame 13, and the output end of the motor 14 is connected to the hollow tube 7 and the central rotating tube 6 through the bevel gear transmission unit 15.

[0031] According to this specific embodiment, the motor 14 is installed on the frame 3 via the mounting frame 13 , and the output end of the motor 14 drives the hollow tube 7 and the central rotating tube 6 to rotate via the bevel gear transmission unit 15 .

[0032] Furthermore, the small-scale paddle-type material distribution and drying device also includes a fan 16, a pipe 17 and a rotary joint 18, the rotary joint 18 is connected to the central rotating tube 6, the pipe 17 is arranged between the fan 16 and the rotary joint 18, and a plurality of vents 23 are arranged at the bottom of the central rotating tube 6.

[0033] According to this specific embodiment, the fan 16 delivers the gas to the vent 23 through the pipe 17 and the rotary joint 18. The gas blown out through the vent 23 can further react the harmful substances that have not reacted completely in the flue gas while ensuring the temperature, thereby reducing the emission of harmful substances.

[0034] Furthermore, the plurality of vents 23 are all arranged at an angle.

[0035] According to this specific embodiment, the vent 23 is tilted to prevent the vent 23 from being blocked by materials.

[0036] Furthermore, the small-scale furnace paddle-type material distribution and drying device also includes a plurality of material dividing and crushing blades 19 , and the plurality of material dividing and crushing blades 19 are arranged on the corresponding arc-shaped stirring paddles 11 .

[0037] According to this specific embodiment, by providing a plurality of the material dividing and crushing blades 19, it is possible to conveniently crush the material and discharge the material downward.

[0038] Furthermore, an air outlet 24 is provided on the arc-shaped stirring paddle 11 .

[0039] According to this specific embodiment, by providing the exhaust port 24, the air permeability inside the material can be enhanced.

[0040] A small-scale furnace paddle-type material distribution and drying device according to the present embodiment is used. When the material to be incinerated enters the frame 3 through the feed port 21, the power assembly drives the central rotating tube 6 and the hollow tube 7 to rotate, and the rotation of the hollow tube 7 drives the spiral blade 10 to rotate. The spiral blade 10 can facilitate the feeding of the material into the furnace body 1. After the material enters the furnace body 1, it falls onto the loading plate 8. At this time, the material on the loading plate falls to the bottom through the discharge port 22 for combustion, and the hollow tube 7 drives the stirring unit to the loading plate. The materials on the furnace body 1 are stirred and scraped off to avoid accumulation on the loading plate. Due to the rotation of the loading plate, part of the materials will fall onto the inner wall of the furnace body 1. At this time, the rotation of the loading plate will drive the first-stage scraper rake 9, the second-stage scraper rake 26 and the third-stage scraper rake 27 to rotate to scrape the materials on the inner wall of the furnace body 1 to prevent the materials from being retained on the conical surface of the furnace body 1 and affecting the movement of the materials. The smoke generated by the combustion is discharged through the smoke exhaust port 20. In this way, the technical problems that the existing pushing device in the prior art has a poor pushing effect and the materials are easy to accumulate and affect the incineration effect are solved.
