DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] A waste treatment rotary kiln with a loading device according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0040] See also Figures 1-11 According to an embodiment of the present application, a waste treatment rotary kiln with a feeding device includes: a rotary kiln body 10, a heat reflux part 20 and a feeding and heat mixing part 30.

[0041] Among them, the hot gas flowing out during combustion of the rotary kiln body 10 is recovered by the heat reflux part 20, and the recovered hot gas can preheat the solid material particles fed by the feeding and mixing part 30, thereby improving the processing efficiency of the rotary kiln body 10 for the material and saving the use of heat and energy.

[0042] See also Figure 1-Figure 4 、 Figure 7 and Figure 8A loading bin 110 is provided at one end of the rotary kiln body 10, and a top support assembly 120 is installed on the side of the loading bin 110. The heat reflux part 20 includes a disc cover 210 and an air guide duct 220. The two ends of the air guide duct 220 are respectively connected to the exhaust port of the heating end of the rotary kiln body 10 and the disc cover 210. The loading and heat mixing part 30 includes a leg frame 310, a lower disc shell 320, a column 330, a loading disc 340, a rotation drive assembly 350 and a blocking adjustment member 360. The bottom end of the column 330 is fixed to the leg frame 310, and the lower disc shell 320 is rotatably matched with the column 330. The bottom of the lower disc shell 320 can be provided with a bearing seat that is rotatably matched with the column 330. The disc cover 210 and the loading disc 340 are both fixedly sleeved on the outside of the column 330, and the disc cover 210, the loading disc 340 and the column 330 can be fixed by welding. The tray cover 210 is located above the lower tray housing 320. A feed pipe 370 is provided on the upper tray 340, feeding the material into the lower tray housing 320. A feed port 321 is provided on the bottom wall of the lower tray housing 320. A blocking adjustment member 360 is installed within the feed port 321 to cooperate with the top support assembly 120 for unloading. A rotation drive assembly 350 is installed on the leg frame 310 to drive the lower tray housing 320. The lower tray housing 320 can be made of a metal material with good thermal conductivity. The exteriors of the lower tray housing 320, the tray cover 210, and the air duct 220 can all be provided with an insulation layer to reduce heat loss.

[0043] The operating principle of this waste treatment rotary kiln with a loading device is as follows: the hot air generated by combustion in the rotary kiln body 10 is recirculated into the interior of the kiln housing 210 via the air duct 220. A fan can also be installed on the air duct 220 to adjust the flow rate of the hot air recirculation. Granular solid material is transported to the interior of the loading tray 340 via a screw feeder or a conveyor belt. The loading tray 340 has a conical bottom. Granular solid material fed into the loading tray 340 flows down the conical surface of the bottom of the loading tray 340 into the discharge pipe 370. Material entering the discharge pipe 370 is then conveyed into the interior of the lower tray 320. Because the hot air is directed into the cavity between the tray housing 210 and the lower tray housing 320 by the coordination of the air duct 220 and the tray housing 210, the solid waste particles entering the cavity between the tray housing 210 and the lower tray housing 320 are preheated.

[0044] Material discharged from discharge tube 370 is transported to a central area near lower housing 320. The rotational drive assembly 350 drives lower housing 320 to rotate about rod 330. The rotating lower housing 320, through centrifugal force, disperses the granular material within it onto its inner surface. This dispersion of granular material increases its contact area with the hot air and the bottom wall of lower housing 320, allowing the granular solid waste material to be preheated more quickly. While the rotational drive assembly 350 drives lower housing 320 to rotate and preheat the solid waste material within, the centrifugal force causes the granular waste material within lower housing 320 to gradually move closer to the inner wall of lower housing 320. When it is necessary to unload the material into the upper bin 110 at the end of the rotary kiln body 10, the top support assembly 120 rises upward, and the rotating lower disk shell 320 drives the blocking adjustment member 360 at the bottom to rotate together. When the blocking adjustment member 360 contacts the top support assembly 120, the granular solid waste inside the lower disk shell 320 will be unloaded from the discharge port 321 located above the upper bin 110 to the interior of the upper bin 110, that is, the preheated granular solid material is unloaded into the interior of the rotary kiln body 10.

[0045] Compared with the traditional loading method, the waste treatment rotary kiln with a loading device can preheat the granular solid waste by using the gas waste heat of the rotary kiln body 10 through the cooperation of the components in the heat reflux part 20 and the loading and mixing heat part 30, thereby improving the processing efficiency of the waste inside the rotary kiln body 10.

[0046] In the above specific implementation, please refer to Figure 2 and Figure 6 The top support assembly 120 includes a hydraulic cylinder 121 and a push rod 122. The hydraulic cylinder 121 is installed on one side of the upper hopper 110, and the push rod 122 is fixed to the top of the hydraulic cylinder 121. The blocking adjustment member 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 plate shell 320. The cover plate 361 is located inside the discharge port 321, and the cover plate 361 is fixedly connected to the bracket 364. The bottom of the guide block 362 is set as an arc-shaped guide surface 365. The push rod 122 is set as a bending structure that matches the arc-shaped guide surface 365, and the upper section of the push rod 122 is a rod-shaped structure.

[0047] When unloading into the upper hopper 110 is required, the output rod end of the hydraulic cylinder 121 drives the push rod 122 to a position below the guide block 362. When unloading into the upper hopper 110 is required, the output rod end of the hydraulic cylinder 121 drives the push rod 122 upward. The cover plate 361 and the guide block 362, connected by the buffer 363 and the bracket 364, rotate along with the lower shell 320. When the curved guide surface 365 at the bottom of the rotating guide block 362 contacts the push rod 122, the top of the push rod 122 follows the curved guide surface 365 to lift the upper cover plate 361. Simultaneously, the buffer 363 is compressed, forming a gap between the cover plate 361 and the discharge port 321. The granular material centrifuged from the lower shell 320 can then fall through this gap into the upper hopper 110, completing the loading process. When the guide block 362 moves out to the area covered by the ejector rod 122 , the gap between the cover plate 361 and the discharge port 321 is blocked again by the elastic force of the buffer 363 , and the material in the lower shell 320 will not be discharged from the discharge port 321 .

[0048] Furthermore, a lip plate 366 is provided on the upper outer edge of the cover plate 361. The cover plate 361 and the lip plate 366 are integrally formed, and the lip plate 366 is located above the discharge opening 321. The lip plate 366 can cover the discharge opening 321, and the buffer 363 can be adjusted to exert a better pulling force on the cover plate 361, so that the cover plate 361 can more tightly seal the discharge opening 321.

[0049] For specific settings, see Figure 5 The rotation drive assembly 350 includes a motor 351, a first sprocket 352, a second sprocket 353, a chain 354, a shaft 355, and a transmission wheel 356. The motor 351 is mounted in conjunction with the leg frame 310. The first sprocket 352 is fixedly mounted on the output rod end of the motor 351. The shaft 355 is rotatably mounted on the leg frame 310. The transmission wheel 356 is fixedly mounted on the exterior of the shaft 355. The second sprocket 353 is fixedly mounted on one end of the shaft 355. The chain 354 connects the first and second sprockets 352, 353. The output shaft end of the motor 351 drives the first sprocket 352 to rotate. The cooperation between the second sprocket 353 and the chain 354 drives the shaft 355 to rotate. The rotating shaft 355 drives the transmission wheel 356 to roll. The transmission wheel 356, through friction, drives the lower housing 320 to rotate around the pillar 330. The feeding and mixing heat part 30 also includes auxiliary wheels 390, which are installed above the leg frame 310 and contact the bottom surface of the lower plate shell 320. The auxiliary wheels 390 are used to auxiliary support the lower plate shell 320 so that the lower plate shell 320 is more stable when rotating.

[0050] For details, please refer to Figure 7The feeding and mixing heat part 30 further includes a web 380, which 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.

[0051] For specific settings, see Figure 4 and Figure 7 The material discharge port 321 and the blocking adjustment member 360 are both arranged in a ring array at the bottom of the lower plate shell 320. The plate cover 210 is provided with a connecting port 230, and the end of the air guide duct 220 away from the rotary kiln body 10 is connected to the connecting port 230.

[0052] The materials loaded into the loading tray 340 in the waste treatment rotary kiln with a loading device can be directly dropped into the lower plate shell 320 through the discharge pipe 370. If the materials dropped into the lower plate shell 320 can be rolled quickly, the heating and preheating efficiency of the materials can be improved.

[0053] See also Figure 7 and Figure 9 The waste treatment rotary kiln with a loading device also includes a material turning section 40, which comprises a cylinder seat 410, an articulated seat 420, a fixed block 430, a connecting rod 440, a blade 450, a spacer 460, an arc frame 470, and a support block 480. The cylinder seat 410 is fixedly mounted on the exterior of the column 330. The articulated seat 420 connects the cylinder seat 410 and the fixed block 430, allowing the fixed block 430 to rotate vertically. One end of the connecting rod 440 is rotatably mounted with the fixed block 430. The end surface of the fixed block 430 may be provided with a bearing seat that rotatably cooperates with the connecting rod 440. Multiple blades 450 are fixedly arranged in a ring array on the outside of the connecting rod 440, multiple groups of arc frames 470 connect two adjacent blades 450 at equal distances, the arc frames 470 are set on the outer edge of the blade 450, the support block 480 is fixedly set on the top of the cover plate 361, and the support block 480 is located below the other end of the connecting rod 440, and multiple groups of connecting rods 440, hinged seats 420, and fixed blocks 430 are arranged in a ring array on the outside of the cylinder seat 410.

[0054] When solid waste particles within the lower housing 320 fall through the discharge pipe 370 into the lower housing 320, the rotating lower housing 320 not only disperses the waste particles that have fallen onto it through centrifugal force, but also simultaneously drives the connecting rod 440 to rotate through the blades 450 and the curved frame 470 due to friction between the rotating lower housing 320 and the curved frame 470. In other words, the blades 450 of the connecting rod 440 are constantly rotating due to the friction between the lower housing 320 and the curved frame 470. The arrangement of multiple sets of curved frames 470 forms a circular structure located at the outer edge of the blades 450, making it easier for the blades 450 to rotate outside the connecting rod 440, thereby reducing the resistance of the blades 450 to flip the solid waste particles within the lower housing 320. Rotating blades 450 pre-disperse the solid granular waste falling from discharge tube 370. Combined with the centrifugal action of lower housing 320, this further enhances the efficiency of preheating the solid waste. Blades 450 are made of a metal plate with excellent thermal conductivity. They are pre-heated to a high temperature by the hot air inside lower housing 320. When heated, blades 450 simultaneously rotate the solid granular waste and transfer heat to the waste, further enhancing preheating efficiency.

[0055] As the rotating lower housing 320 drives the cover plate 361 to rotate, the guide block 362 at the bottom of the cover plate 361 cooperates with the push rod 122 to lift the cover plate 361. At this point, the support block 480 at the top of the cover plate 361 moves upward, lifting one end of the connecting rod 440, causing the outer pad 460 of the vane 450 to break away from the bottom surface of the lower housing 320, thereby rapidly moving the vane 450 upward. When the guide block 362 breaks away from the push rod 122, the connecting rod 440 drives the vane 450 to rapidly drop and contact the lower housing 320. This allows any solid waste particles adhering to the vane 450, the curved frame 470, and the connecting rod 440 to fall into the interior of the lower housing 320 during the vibration, thus ensuring that the waste adhering to the vane 450, the pad 460, and the connecting rod 440 can be completely discharged.

[0056] The solid granular waste in the lower shell 320 of the waste treatment rotary kiln with a feeding device cannot be well guided and dispersed into the discharge port 321 to complete the discharge.

[0057] See also Figure 7 、 Figure 10 and Figure 11The waste treatment rotary kiln with a loading device also includes a material turning auxiliary portion 50, which includes a wedge-shaped diverter housing 510, curved strips 520, and an outer protective layer 530. The diverter housing 510 is positioned between adjacent discharge ports 321. A cavity 540 is provided at the bottom of the diverter housing 510, and the diverter housing 510 is fixed to the lower housing 320. The curved strips 520 are fixed to the inner wall of the lower housing 320, with one end of the curved strips 520 fixedly connected to the tip of the diverter housing 510. The outer protective layer 530 is disposed on the exterior of the curved strips 520.

[0058] When the outer sheath 530 of the curved slats 520 contacts the backing strips 460 on the outer edge of the blades 450, it increases the rotational friction of the blades 450, enabling the blades 450 to better rotate and flip the solid granular waste within the lower housing 320. Furthermore, the outer sheath 530 can be made of rubber. When the backing strips 460 and outer sheath 530 contact, they provide better protection for the blades 450 and the curved slats 520. When the backing strips 460 on the rolling blades 450 contact the outer sheath 530, they cause the blades 450 to vibrate, allowing the blades 450 to more effectively disperse the material when the blades 450 and the backing strips 460 flip it, thereby improving heating efficiency. The dispersed, preheated material is then directed along the wedge-shaped diverter housing 510 to the area above the discharge port 321 located between adjacent diverter housings 510. This structural design allows for more efficient and effective material unloading.
