The filter box 5 is provided with a filter component 7 that cooperates with the air guide pipe 23. The filter component 7 is used to filter and remove impurities from the smoke discharged from the air guide pipe 23 to the filter box 5. The inner cavity of the kiln body 2 is provided with a lateral turning mechanism 6. The lateral turning mechanism 6 includes a turning plate 61, a positioning component 62 and a driving component 63. The turning plate 61 is provided with multiple groups. The positioning component 62 is located in the inner cavity of the kiln body 2 and is in contact with the turning plate 61. The material plates 61 are connected, and the positioning component 62 is used to control multiple groups of flipping plates 61 to be distributed horizontally in parallel in the inner cavity of the kiln body 2. The driving component 63 includes a swinging part 631 and a transmission part 632. The swinging part 631 is connected to the flipping plate 61, and the transmission part 632 is connected to the swinging part 631. When the kiln body 2 rotates around its own axis, the transmission part 632 controls the multiple groups of flipping plates 61 to swing back and forth in the left and right directions at the bottom of the kiln body 2 by cooperating with the swinging part 631.

[0024] During use, the material to be dried, roasted or calcined is put into the kiln body 2 through the material guide port 21, and the gas pipe 31 cooperates with the combustion port 32 to roast the material in the inner cavity of the kiln body 2. When roasting the material, the rotating component 4 controls the kiln body 2 to rotate continuously between the two groups of vertical plates 11.

Initially, the positioning component 62 supports and positions the multiple groups of flipping plates 61, so that the multiple groups of flipping plates 61 are arranged horizontally at the bottom of the kiln body 2. When the kiln body 2 rotates to flip the material, the swing part 631 cooperates with the transmission part 632 to control the multiple groups of flipping plates 61 to swing back and forth. When the kiln body 2 rotates, the material is controlled to roll in the front and back directions. While the material rolls in the front and back directions, the flipping plate 61 can control the material to flip in the left and right directions, effectively improving the stirring effect of the material, so that the material is fully roasted.

During operation, the first motor 42 rotates the transmission gear plate 43, which engages with the ring gear 41 to drive the kiln body 2 to rotate continuously between the two sets of vertical plates 11.

After the flue gas is filtered by the filter ring 73, it is discharged to the outside of the filter box 5 through the opening 51. After the filter ring 73 adsorbs the impurities, the squeezing roller 74 squeezes the filter ring 73, so that the sewage containing impurities in the filter ring 73 flows into the filter box 5, and the impurities are precipitated in the filter box 5.

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, as a preferred embodiment of the present invention, the positioning assembly 62 includes a group of connecting rods 621 fixedly installed on the side walls of the vertical plates 11, the connecting rods 621 extend through the through holes 22 to the inner cavity of the kiln body 2 and are fixedly installed with a supporting plate 622, the side walls of the supporting plate 622 are fixedly installed with a horizontal cylinder 623 located in the inner cavity of the kiln body 2, the bottom wall of the horizontal cylinder 623 is provided with multiple groups of bottom holes 624 distributed in parallel, and the top end of the flipping plate 61 is rotatably installed in the bottom hole 624.

[0030] When in use, the connecting rod 621 supports and positions the supporting plate 622, and the supporting plate 622 supports and positions the transverse cylinder 623. When the kiln body 2 rotates, the transverse cylinder 623 remains relatively stationary in the inner cavity of the kiln body 2, and the transverse cylinder 623 supports and positions the flipping plate 61. When the kiln body 2 rotates and thus controls the rolling of the material, the swinging part 631 controls the flipping plate 61 to swing back and forth in the left and right directions under the transverse cylinder 623. The flipping plate 61 can further improve the stirring and flipping effect of the material.

[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 As shown, as a preferred embodiment of the present invention, the swinging part 631 includes a fan-shaped toothed disk 6311 fixedly installed on the top of the turning plate 61, and the fan-shaped toothed disk 6311 extends into the horizontal cylinder 623.

The gear ring 6323 engages with the fixed gear plate 6322 for transmission, which can drive the rotating rod 6321 to rotate on the surface of the bearing plate 622. The rotating rod 6321 drives the active bevel gear plate 6326 to rotate. The active bevel gear plate 6326 engages with the driven bevel gear plate 6325 for transmission, which can drive the rotating column 6324 to rotate. The rotating column 6324 drives the control disk 6329 to rotate synchronously in the horizontal cylinder 623. The control disk 6329 drives the guide column 6320 to rotate synchronously. The guide column 6320 cooperates with the guide groove 6328 to push the guide plate 6327 to move back and forth in the left and right directions. The guide plate 6327 drives the horizontal plate 6313 to move back and forth synchronously in the left and right directions in the horizontal cylinder 623.

[0035] like Figure 1 、 Figure 2 As shown, as a preferred embodiment of the present invention, a base 8 is provided under the workbench 1, and a support plate 9 is rotatably installed on the surface of the base 8. The top of the support plate 9 is rotatably connected to the bottom wall of the workbench 1, and an electric telescopic rod 10 is rotatably installed on the side of the base 8 away from the support plate 9. The telescopic end of the electric telescopic rod 10 is rotatably connected to the bottom wall of the workbench 1.

[0036] When in use, the electric telescopic rod 10 pushes the workbench 1 to rotate to a tilted state, and the kiln body 2 rotates to a tilted state synchronously, which not only adjusts the combustion angle of the material in the kiln body 2 but also facilitates the discharge of the roasted material through the material guide port 21.

[0037] The working principle of the present invention is as follows: when in use, the material to be dried, roasted or calcined is placed into the kiln body 2 through the material guide port 21. The gas pipe 31 cooperates with the combustion port 32 to roast the material in the inner cavity of the kiln body 2. When the material is roasting, the first motor 42 drives the transmission gear plate 43 to rotate. The transmission gear plate 43 engages with the gear ring 41 to drive the kiln body 2 to continuously rotate between the two sets of vertical plates 11. When the kiln body 2 rotates, the material is synchronously rolled in the inner cavity of the kiln body 2, which can be initially turned over so that the batch of materials can be fully roasted. Initially, the bearing plate 622 supports and positions the transverse cylinder 623. When the kiln body 2 rotates, the transverse cylinder 623 remains relatively stationary in the inner cavity of the kiln body 2. The transverse cylinder 623 supports and positions the flipping plate 61. The kiln body 2 rotates and drives the gear ring 6323 to rotate synchronously. The gear ring 6323 engages with the fixed gear disc 6322 for transmission, which can drive the rotating rod 6321 to rotate on the surface of the bearing plate 622. The rotating rod 6321 drives the active bevel gear disc 6326 to rotate. The active bevel gear disc 6326 rotates. The toothed disc 6326 meshes with the driven helical toothed disc 6325 to drive the rotating column 6324. The rotating column 6324 drives the control disc 6329 to rotate synchronously within the horizontal cylinder 623. The control disc 6329 drives the guide column 6320 to rotate synchronously. The guide column 6320 cooperates with the guide slot 6328 to propel the guide plate 6327 back and forth in the horizontal direction. The guide plate 6327 drives the horizontal plate 6313 to move synchronously back and forth within the horizontal cylinder 623. The horizontal plate 6313 drives the rack 6314 to reciprocate synchronously. During this reciprocating motion, the rack 6314 meshes with the fan-shaped toothed disc 6311, driving the tipping plate 61 to swing back and forth below the bottom hole 624. As the kiln body 2 rotates, the material is controlled to roll forward and backward. Simultaneously, the tipping plate 61 flips the material left and right, effectively enhancing the material agitation and ensuring a more complete roasting process.

[0038] The flue gas generated by heating the material is transported to the filter box 5 through the air duct 23. An appropriate amount of water is injected into the filter box 5. The second motor 75 drives the rotating shaft 71 to rotate. The rotating shaft 71 cooperates with the bracket 72 to drive the filter ring 73 to rotate in the filter box 5. After the filter ring 73 absorbs water, the adsorption effect of impurities in the flue gas can be effectively improved. After the flue gas is filtered by the filter ring 73, it is discharged to the outside of the filter box 5 through the opening 51. After the filter ring 73 adsorbs the impurities, the squeezing roller 74 squeezes the filter ring 73, so that the sewage containing impurities in the filter ring 73 flows into the filter box 5, and the impurities are precipitated in the filter box 5.

[0039] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
