Apparently, the described embodiments are some, but not all, of the embodiments of this application.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0026] A waste treatment rotary kiln with a feeding device according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0027] Please refer to Figures 1 - 11 , a waste treatment rotary kiln with a feeding device according to an embodiment of this application includes: a rotary kiln main body 10, a heat reflux part 20, and a feeding and heat mixing part 30.

[0028] Among them, the hot gas flowing out during the combustion of the rotary kiln main body 10 is recovered by the heat reflux part 20, and the recovered hot gas can preheat the solid material particles fed through the cooperation of the feeding and heat mixing part 30, improving the processing efficiency of the rotary kiln main body 10 on the material, and also saving the use of heat energy.

[0029] Please refer to Figures 1 - 4 , Figure 7 and Figure 8, a feeding bin 110 is arranged at one end of the rotary kiln main body 10, and a supporting component 120 is installed on the side of the feeding bin 110. The heat reflux part 20 includes a disc cover 210 and a gas guiding pipeline 220. The two ends of the gas guiding pipeline 220 are respectively communicated with the exhaust port of the heating end of the rotary kiln main body 10 and the disc cover 210. The feeding and heat mixing part 30 includes a leg frame 310, a lower disc shell 320, a column rod 330, a feeding disc 340, a rotation driving component 350 and a plugging and adjusting part 360. The bottom end of the column rod 330 is fixedly arranged with the leg frame 310, the lower disc shell 320 is rotationally matched with the column rod 330, and a bearing seat rotationally matched with the column rod 330 can be arranged at the bottom of the lower disc shell 320. The disc cover 210 and the feeding disc 340 are both fixedly sleeved outside the column rod 330, and the disc cover 210 and the feeding disc 340 can be fixed to the column rod 330 by welding. The disc cover 210 is located above the lower disc shell 320. A feeding pipe 370 for feeding materials to the lower disc shell 320 is arranged on the feeding disc 340, a feeding port 321 is arranged on the inner bottom wall of the lower disc shell 320, the plugging and adjusting part 360 is installed inside the feeding port 321 to cooperate with the supporting component 120 for discharging materials, and the rotation driving component 350 is installed on the leg frame 310 to drive the lower disc shell 320 to rotate. The lower disc shell 320 can be made of a metal material with good heat conduction, and heat insulation layers can be arranged outside the lower disc shell 320, the disc cover 210 and the gas guiding pipeline 220 to reduce heat loss.

[0030] The working principle of the waste treatment rotary kiln with a feeding device is as follows: The hot gas generated during the combustion of the rotary kiln main body 10 can flow back into the inside of the disc cover 210 through the gas guiding pipeline 220. A fan can also be installed on the gas guiding pipeline 220 to adjust the flow rate of the hot gas reflux. Granular solid materials are conveyed into the inside of the feeding disc 340 through a screw feeder or a conveyor belt. The bottom of the feeding disc 340 is of a conical structure, and the granular solid materials fed into the inside of the feeding disc 340 slide down along the conical surface at the bottom of the feeding disc 340 into the inside of the feeding pipe 370. The materials entering the inside of the feeding pipe 370 will be conveyed into the inside of the lower disc shell 320. Since the hot gas has been guided into the cavity between the disc cover 210 and the lower disc shell 320 through the cooperation of the gas guiding pipeline 220 and the disc cover 210, the solid particle waste entering the cavity inside the disc cover 210 and the lower disc shell 320 is preheated.

[0031] The materials fed from the feeding pipe 370 reach the middle area near the lower disc housing 320. The rotation drive assembly 350 can drive the lower disc housing 320 to rotate around the column rod 330. The rotating lower disc housing 320 can disperse the granular materials falling inside the lower disc housing 320 on the inner surface of the lower disc housing 320 by the action of centrifugal force. The granular materials dispersed on the inner surface of the lower disc housing 320 increase the contact area with the hot air and also increase the contact area with the bottom wall of the lower disc housing 320, enabling the granular solid waste falling into the lower disc housing 320 to be preheated more quickly. While the rotation drive assembly 350 drives the lower disc housing 320 to rotate to drive the solid particle waste inside to be preheated, under the action of centrifugal force, the granular waste inside the lower disc housing 320 gradually approaches the inner wall of the lower disc housing 320. When it is necessary to unload the materials to the feeding bin 110 at the end of the rotary kiln main body 10, the supporting assembly 120 rises upward. The rotating lower disc housing 320 drives the bottom plugging and adjusting part 360 to rotate together. When the plugging and adjusting part 360 contacts the supporting assembly 120, the granular solid waste inside the lower disc housing 320 will be unloaded into the feeding bin 110 from the feeding port 321 above the feeding bin 110, that is, the preheated granular solid materials are unloaded into the rotary kiln main body 10.

[0032] Compared with the traditional feeding method, the waste treatment rotary kiln with the feeding device can preheat the granular solid waste by using the waste heat of the gas in the rotary kiln main body 10 through the cooperation of the components in the heat reflux part 20 and the feeding and heat mixing part 30, and can improve the processing efficiency of the waste inside the rotary kiln main body 10.

[0033] In the above specific implementation manner, please refer to Figure 2 and Figure 6 , the supporting assembly 120 includes a hydraulic cylinder 121 and a top rod 122. The hydraulic cylinder 121 is installed on one side of the feeding bin 110, and the top rod 122 is fixed to the top of the hydraulic cylinder 121. The plugging and adjusting part 360 includes a cover plate 361, a guide block 362, a buffer 363 and a bracket 364. The buffer 363 connects the bracket 364 and the lower disc housing 320. The cover plate 361 is located inside the feeding port 321, and the cover plate 361 is fixedly connected to the bracket 364. The bottom of the guide block 362 is provided with an arc-shaped guide surface 365. The top rod 122 is provided with a bent structure that matches the arc-shaped guide surface 365, and the upper section of the top rod 122 is a rod-shaped structure.

[0034] When it is necessary to discharge materials into the upper feed bin 110, the rod end of the hydraulic cylinder 121 drives the ejector rod 122 to move to the position below the guide block 362. When it is necessary to discharge materials into the upper feed bin 110, the rod end of the hydraulic cylinder 121 drives the ejector rod 122 to move upward. The cover plate 361 and the guide block 362 rotate together with the lower disk housing 320 through the connection of the buffer 363 and the support 364. When the arc-shaped guide surface 365 at the bottom of the rotating guide block 362 contacts the ejector rod 122, the top end of the ejector rod 122 can push up the upper cover plate 361 along the arc-shaped guide surface 365, and at the same time, the buffer 363 is compressed. A gap is formed between the cover plate 361 and the material discharge port 321, and the centrifuged granular broken materials inside the lower disk housing 320 can fall into the upper feed bin 110 through this gap to complete the feeding. When the guide block 362 moves out of the covered area of the ejector rod 122, under the elastic force of the buffer 363, the gap between the cover plate 361 and the material discharge port 321 is blocked again, and the materials in the lower disk housing 320 will not be discharged from the material discharge port 321.

[0035] Furthermore, a flange 366 is provided on the outer edge above the cover plate 361. The cover plate 361 and the flange 366 are integrally formed, and the flange 366 is located above the material discharge port 321. The flange 366 can cover above the material discharge port 321, and can adjust the buffer 363 to have a better pulling force on the cover plate 361, so that the cover plate 361 can block the material discharge port 321 more tightly.

[0036] For specific settings, please refer to Figure 5 The rotation drive assembly 350 includes a motor 351, a first sprocket 352, a second sprocket 353, a chain 354, a shaft rod 355 and a transmission wheel 356. The motor 351 is installed in cooperation with the leg frame 310. The first sprocket 352 is fixedly sleeved on the rod end of the output of the motor 351. The shaft rod 355 is rotatably arranged with the leg frame 310. The transmission wheel 356 is fixedly sleeved outside the shaft rod 355. The second sprocket 353 is fixedly sleeved on one end of the shaft rod 355. The chain 354 connects the first sprocket 352 and the second sprocket 353. The output shaft end of the motor 351 drives the first sprocket 352 to rotate, drives the shaft rod 355 to rotate through the cooperation of the second sprocket 353 and the chain 354. The rotating shaft rod 355 drives the transmission wheel 356 to roll, and the lonely transmission wheel 356 drives the lower disk housing 320 to rotate around the column rod 330 through friction. The feeding and mixing and heating part 30 further includes an auxiliary wheel 390. The auxiliary wheel 390 is installed above the leg frame 310 and contacts the bottom surface of the lower disk housing 320. The auxiliary wheel 390 is used to assist in supporting the lower disk housing 320 to make the lower disk housing 320 more stable during rotation.

[0037] Specifically, please refer to Figure 7, the feeding and mixing section 30 further includes a web 380, and the web 380 can be fixedly connected to the feeding tray 340 and the tray cover 210 by welding. The web 380 is used to reinforce and support the feeding tray 340 and the tray cover 210.

[0038] For specific settings, please refer to Figure 4 and Figure 7 , the discharge port 321 and the plugging and adjusting member 360 are both arranged in a plurality of groups in an annular array at the bottom of the lower pan shell 320. A connection port 230 is arranged on the tray cover 210, and one end of the air guide pipe 220 far from the rotary kiln main body 10 is communicated with the connection port 230.

[0039] In the above waste treatment rotary kiln with a feeding device, the material fed into the feeding tray 340 can directly fall into the interior of the lower pan shell 320 through the feeding pipe 370. If the material falling into the lower pan shell 320 can be quickly tumbled, the heating and preheating efficiency of the material can be improved.

[0040] Please refer to Figure 7 and Figure 9 , the waste treatment rotary kiln with a feeding device further includes a material tumbling section 40, and the material tumbling section 40 includes a cylinder base 410, a hinge seat 420, a fixing block 430, a connecting rod 440, a blade 450, a cushion strip 460, an arc-shaped frame 470 and a support block 480. The cylinder base 410 is fixedly sleeved outside the column rod 330, the hinge seat 420 connects the cylinder base 410 and the fixing block 430, and the hinge seat 420 can enable the fixing block 430 to rotate in the vertical direction. One end of the connecting rod 440 is rotatably arranged with the fixing block 430, and a bearing seat can be arranged on the end face of the fixing block 430 to rotatably cooperate with the connecting rod 440. A plurality of blades 450 are fixedly arranged in an annular array outside the connecting rod 440, a plurality of arc-shaped frames 470 are equidistantly connected to adjacent two blades 450, the arc-shaped frames 470 are arranged on the outer edge of the blades 450, the support block 480 is fixedly arranged on the top of the cover plate 361, and the support block 480 is located below the other end of the connecting rod 440. A plurality of groups of connecting rods 440, hinge seats 420 and fixing blocks 430 are arranged in an annular array outside the cylinder base 410.

[0041] When the solid waste particles inside the lower pan shell 320 fall into the lower pan shell 320 through the feeding pipe 370, in addition to the rotating lower pan shell 320 driving the waste falling on it to disperse by centrifugal force, and at the same time the rotating lower pan shell 320 drives the connecting rod 440 to rotate through the friction with the arc-shaped frame 470, and drives the connecting rod 440 to rotate through the vane 450 and the arc-shaped frame 470. That is, under the friction force between the lower pan shell 320 and the arc-shaped frame 470, the vane 450 of the connecting rod 440 will always be in a rotating state. The arrangement of multiple arc-shaped frames 470 can form a circular structure at the outer edge of the vane 450, making it easier for the vane 450 to rotate outside the connecting rod 440, that is, reducing the resistance of the vane 450 to flip the solid particle waste inside the lower pan shell 320. The rotating vane 450 can pre-disperse the solid particle waste falling from the feeding pipe 370, and then cooperate with the centrifugal action of the lower pan shell 320 itself on the waste, which can further improve the dispersion and preheating efficiency of the solid waste. Among them, the vane 450 is made of a metal material plate with good heat conduction. The vane 450 inside the lower pan shell 320 can be pre-heated to a higher temperature by hot air. When the heated vane 450 flips the solid particle waste, it also transfers heat to the waste, that is, further improving the preheating efficiency of the waste.

[0042] When the rotating lower pan shell 320 drives the cover plate 361 to rotate, when the guide block 362 at the bottom of the cover plate 361 cooperates with the ejector rod 122 to lift the cover plate 361, the support block 480 at the top of the cover plate 361 moves upward to lift one end of the connecting rod 440, so that the cushion strip 460 outside the vane 450 is separated from the bottom surface of the lower pan shell 320, that is, the vane 450 quickly moves upward. When the guide block 362 is separated from the ejector rod 122, the connecting rod 440 drives the vane 450 to quickly fall and contact the lower pan shell 320, so that the solid waste particles attached to the vane 450, the arc-shaped frame 470, and the connecting rod 440 can fall into the lower pan shell 320 during vibration, that is, the waste attached to the vane 450, the cushion strip 460, and the connecting rod 440 can be discharged cleanly.

[0043] The solid particle waste in the lower pan shell 320 of the waste treatment rotary kiln with the feeding device cannot be well diverted and dispersed into the feeding port 321 for discharging.

[0044] Please refer to Figure 7 、 Figure 10 and Figure 11, the waste treatment rotary kiln with a feeding device further includes a turning auxiliary part 50, and the turning auxiliary part 50 includes a shunt housing 510 with a wedge-shaped structure, an arc-shaped strip 520, and an outer protective layer 530. The shunt housing 510 is arranged between adjacent blanking ports 321. A cavity 540 is provided at the bottom of the shunt housing 510, and the shunt housing 510 is fixedly arranged with the lower disc housing 320. The arc-shaped strip 520 is fixed to the inner wall of the lower disc housing 320, and one end of the arc-shaped strip 520 is fixedly connected to the tip of the shunt housing 510, and the outer protective layer 530 is arranged outside the arc-shaped strip 520.

[0045] When the outer protective layer 530 outside the arc-shaped strip 520 contacts the cushion strip 460 on the outer edge of the vane 450, the rotational friction of the vane 450 can be increased, that is, the vane 450 can rotate and turn the solid granular waste inside the lower disc housing 320 more optimally. And the outer protective layer 530 can be made of rubber material. When the cushion strip 460 contacts the outer protective layer 530, it also has a better protective effect on the vane 450 and the arc-shaped strip 520. When the cushion strip 460 outside the rolling vane 450 contacts the outer protective layer 530 outside the arc-shaped strip 520, it can also cause the vane 450 to vibrate, so that the vane 450 can cooperate with the cushion strip 460 to turn the material more dispersedly, improving the heat absorption efficiency of the material. The dispersed preheated material will flow along the shunt housing 510 with a wedge-shaped structure to the area above the blanking port 321 located between adjacent shunt housings 510. This structural design makes the material unloading more reasonable and efficient.
