Description

Technical Field

[0001] The invention relates to the technical field of material pyrolysis, and in particular to a rotary kiln used for pyrolysis. Background Art

[0002] The rotary kiln separates solid, liquid and gas products through pyrolysis reaction, and can make the materials tumble and move forward continuously during the slow rotation process. This movement mode can ensure that the materials are heated evenly and avoid local overheating or insufficient heating. It can effectively control the temperature and residence time required for the pyrolysis reaction. By setting a heating device outside the kiln, such as a gas burner or an electric heating element, the heat can be transferred to the internal materials for pyrolysis.

[0003] Since the cylinder of the rotary kiln is rotating, the heat transfer mainly relies on the external heating device to heat the cylinder, and then transfer the heat to the material. In this process, the heat loss is relatively large. Compared with some fixed bed pyrolysis equipment, the heat loss of the rotary kiln is larger, resulting in lower thermal efficiency.

[0004] In the patent document with the publication number CN212673226U that has been published, a rotary kiln for pyrolysis is disclosed, which belongs to the field of pyrolysis treatment technology. Its technical solution includes a furnace body, a shell is provided on the furnace body, a support seat is rotatably connected under the shell, a driving device for driving the shell to rotate is provided between the support seat and the shell, one end of the shell is connected to a feed bin, a feeder is provided at the feed bin, and the other end of the shell is connected to a discharge bin. A plurality of pyrolysis chambers are provided in the shell, and hot air channels are left between adjacent pyrolysis chambers. The hot air channels are connected with an air inlet pipe and an air outlet pipe, so that the raw materials to be pyrolyzed in the shell are fully pyrolyzed and the pyrolysis efficiency is improved.

[0005] When the above device is in use, it sets a plurality of pyrolysis chambers in the shell. In devices of the same size, although the plurality of pyrolysis chambers can fully contact with the raw materials to be pyrolyzed, thereby improving the heat transfer, when the rotary kiln is processing a variety of materials, for some materials with high viscosity or special shapes, the small space makes it easy for the materials to be squeezed and agglomerated, blocked, etc., so the processing and transmission efficiency of the raw materials is poor.

[0039] like Figure 1 - Fig. 9As shown, the positioning drive assembly 3 includes two first forward and reverse motors 301 fixedly installed on both sides of the two kiln positioning frames 101, an external rotating rod 303 is fixedly installed on the side of the first forward and reverse motor 301 facing the kiln positioning frame 101, a meshing guide rod 304 is fixedly installed on one side of the external rotating rod 303, a built-in gear block 312 is rotatably installed on the side of the meshing guide rod 304 away from the external rotating rod 303, a turntable positioning block 310 is rotatably installed on the outer side of the built-in gear block 312, the turntable positioning block 310 is fixedly installed on the inner wall of the kiln positioning frame 101, two guide frames 313 are fixedly installed on the outer side of the meshing guide rod 304, a gear positioning block 314 is slidably installed on the side of the guide frame 313 away from the meshing guide rod 304, and the gear positioning block 31 4 is arranged in a meshing state with the built-in gear block 312, a spring block 315 is fixedly installed at the connection between the gear positioning block 314 and the guide frame 313, an electric telescopic rod 307 is fixedly installed on the side of the built-in gear block 312 away from the first forward and reverse motor 301, and the electric telescopic rod 307 is fixedly installed on one side of the built-in threaded turntable 105, and the meshing guide rod 304 passes through the side of the built-in threaded turntable 105 and is fixedly installed with a thread placement guide rod 305, and the outer side of the thread placement guide rod 305 is provided with a transmission thread made according to the kiln requirements of the rotary kiln, and when the thread placement guide rod 305 rotates forward, the thread placement guide rod 305 transports the raw materials input from the raw material pipe on the kiln positioning frame 101 to the residual material output pipe on the kiln positioning frame 101, and the built-in A double-plate clamping frame 302 is fixedly installed on one side of the threaded turntable 105 away from the meshing guide rod 304, and the double-plate clamping frame 302 is attached to the inner wall of the fixed disc 106, and the threaded mounting guide rod 305 is installed on the outer side of the threaded mounting guide rod 305 through the limit block 306. Although the rotary kiln can process a variety of materials, for some materials with high viscosity or special shapes, problems such as agglomeration and blockage may occur. At the same time, for some materials containing large pieces of materials or easy to stick together, the feed port may be blocked, which will not only affect the continuity of production, but also may cause equipment failure. The solid residue after pyrolysis may be blocked at the discharge port due to uneven particle size, coking, etc., and the first forward and reverse motor 301 drives the external rotating rod 3 03 rotates with the threaded guide rod 305, and the threaded guide rod 305 transmits the introduced material to the position of the residual material output pipe by reverse rotation. At this time, the gear positioning block 314 reversely rotates the vertical plane to give pressure to the built-in gear block 312, and the gear positioning block 314 cannot shrink, so the turntable positioning block 310 rotates synchronously with the gear positioning block 314, and the built-in gear block 312 drives the double-plate clamping frame 302 to rotate synchronously through the electric telescopic rod 307 and the built-in threaded turntable 105. Since the furnace positioning frame 101 is in a fixed state, the double-plate clamping frame 302 and the inner wall of the furnace positioning frame 101 are in a state of relative motion. When the threaded guide rod 305 guides the raw material to roll and transport through the external thread and sticks to the inner wall of the furnace positioning frame 101,The double-plate clamping frame 302 contacts it and scrapes it. At the same time, the double-plate clamping frames 302 on both sides can scrape the liquid collection pipe, air flow conveying pipe, residual material output pipe and the surrounding side of the raw material input pipe on the furnace positioning frame 101 to avoid blockage of the raw materials. At the same time, due to the large volume of the raw materials, only part of the impurities, liquids and gases contained in the raw materials can be discharged in one reverse transportation. The first forward and reverse motor 301 drives the built-in threaded turntable 105 to rotate forward, pushing the raw materials in the other furnace positioning frame 101 back to the original position. At this time, due to the forward rotation of the guide frame 313, the inclined surface of the gear positioning block 314 gives pressure to the built-in gear block 312, and the gear positioning block 314 moves inward along the guide frame 313 and the spring block 315 according to the friction force transmitted with the inclined surface of the built-in gear block 312. The built-in gear block 312 is in a nearly stationary state at this time, and the double-plate clamping frame 302 and the threaded guide rod 305 are in a The double plate clamping frame 302 is in a relative motion state. At this time, the raw materials impacting the double plate clamping frame 302 are affected by the rotation force of the threaded placement guide rod 305 and are in a relative cutting motion with the double plate clamping frame 302, so that the agglomerated raw materials are cut and separated. At the same time, the electric telescopic rod 307 drives the built-in threaded turntable 105 and the double plate clamping frame 302 to move toward the engaging turntable 202, and a small amount of raw materials that may be blocked by the scraping rod 308 are pushed into the engaging turntable 202 for decomposition, thereby preventing the various openings of the rotary kiln from being blocked, and at the same time facilitating the recovery of sticky raw materials and improving the pyrolysis efficiency. A plurality of scraping rods 308 are fixedly installed inside the double plate clamping frame 302, and the plurality of scraping rods 308 are arranged in an annular state with respect to the surface of the two-way placement frame 309. When the double plate clamping frame 302 rotates, the plurality of scraping rods 308 are used to fully scrape the raw materials adhering to the inner wall of the kiln positioning frame 101, so that the raw materials fall into the rotary kiln for processing;

[0040] The positioning drive assembly 3 also includes an auxiliary positioning frame 311 fixedly installed on the outside of the furnace positioning frame 101, and a two-way mounting frame 309 is fixedly installed inside the auxiliary positioning frame 311. When the rotary furnace is in operation, it is necessary to use a threaded mounting guide rod 305 to rotate and transmit raw materials. Since there are a lot of raw materials, vibration is easy to occur during transmission. The two-way mounting frame 309 uses the elastic force of the spring to buffer the rotation vibration of the threaded mounting guide rod 305.

[0041] like Figure 2 and Figure 5As shown, the wave-type positioning assembly 4 includes a first side folding frame 401 rotatably mounted on the inner wall of the engaging turntable 202, a folding frame 404 is hingedly connected inside the first side folding frame 401, a second side folding frame 402 is hingedly connected to a side of the folding frame 404 away from the first side folding frame 401, an arc-shaped pull block 403 is fixedly mounted on the second side folding frame 402 and one side of the first side folding frame 401, and the arc-shaped pull block 403 is inserted into the inside of the fixed disc 106. The first side folding frame 401 and the second side folding frame 402 are wavy. When the raw material is passed through the threaded guide rod 305 to another furnace positioning frame 101, the raw material pyrolyzed in the engaging turntable 202 forms a cutting surface with the wave pattern of the second side folding frame 402 during the rotation process, thereby reducing the occurrence of raw material agglomeration and clogging, and avoiding blocking the output port.

[0042] In this embodiment, Figure 4 and Fig.10As shown, the guide assembly 5 includes an auxiliary gear 510 meshingly connected to the outside of the meshing guide rod 304, an auxiliary rotating rod 502 is fixedly installed inside the auxiliary gear 510, and a locking positioning fixing block 501 is rotatably installed on the outside of the auxiliary rotating rod 502. Two groups of bidirectional fixed rods 504 are fixedly installed on the bottom end of the auxiliary rotating rod 502 through a tripod 503. The two groups of bidirectional fixed rods 504 are fixedly installed on the inner wall of the furnace positioning frame 101 through a fixed connecting rod 509. The auxiliary rotating rod 502 passes through one side of the locking positioning fixing block 501 and is fixedly installed with an eccentric rotating rod 507. Two groups of inclined hinge rods 508 are hinged on one side of the eccentric rotating rod 507. The bottom of the inclined hinge rod 508 is hinged with a sliding sleeve block 505. The sliding sleeve block 505 is slidably installed on the bidirectional fixed rod 504. On the outer side of the first forward and reverse motor 301, there are two sliding blocks 505. An auxiliary spring is fixedly installed between the sliding block 505 and the fixed connecting rod 509 on the side of the first forward and reverse motor 301. A push rod 506 is fixedly installed on one side of the other sliding block 505. The push rod 506 passes through one side of the fixed disk 106 and is fixedly installed on one side of the arc-shaped pull block 403. When the meshing guide rod 304 rotates, the auxiliary gear 510 drives the auxiliary gear 510 to rotate by meshing with the meshing guide rod 304. The auxiliary gear 510 drives the auxiliary rotating rod 502 to rotate along the engaging positioning fixed block 501, and the auxiliary rotating rod 502 drives the eccentric rotating rod 507 to rotate. The eccentric rotating rod 507 uses the eccentric wheel characteristics to drive the two tilting hinge rods 508 to rotate along the bidirectional fixed rod 50 4 performs repeated sliding motion within a fixed range, and the two sliding sleeve blocks 505 simultaneously perform reciprocating sliding motion along the bidirectional fixed rod 504. During this process, the sliding sleeve block 505 close to the first forward and reverse motor 301 uses an auxiliary spring to buffer the impact force of the guide assembly 5 during the reciprocating motion, and the other sliding sleeve block 505 drives the sliding sleeve block 505 to slide along the fixed disc 106. When the push rod 506 drives the arc-shaped pull block 403 to move toward the inside of the fixed disc 106, that is, the fixed disc 106 is inserted into the fixed disc 106, the first side folding frame 401 and the second side folding frame 402 slowly become horizontal through the deflectable guide of the folding frame 404. At this time, when the threaded guide rod 305 is transported to the engaging turntable 202 It can pass normally on the second side folding frame 402, while the molten salt and other energy storage materials located at the first side folding frame 401 are relatively scattered. When the arc-shaped pulling block 403 moves away from the fixed disc 106, the first side folding frame 401 and the second side folding frame 402 are in a wavy state, and the first side folding frame 401 wraps the molten salt and other energy storage materials on the surrounding side, so that the heat is concentrated on the engaging turntable 202, and then the material is fully pyrolyzed. In the process of folding the second side folding frame 402, part of the raw materials are assisted to be pushed to the next position, and at the same time, the materials are separated, which is convenient for the materials to be stacked together into blocks, and can also cooperate with the threaded guide block at the threaded guide rod 305 to perform cutting movement, thereby improving the decomposition efficiency of the materials.
