Description

Technical Field

[0001] This invention relates to the technical field of biomass medium-temperature shaping, high-temperature shaping, and hard carbon anode material production and preparation equipment, and particularly to a vertical external heating cyclone furnace. Background Technology

[0002] A cyclone furnace is a highly efficient reaction device that uses high-speed airflow to cause materials to move in a swirling state within the furnace, thereby enhancing the heat and mass transfer processes between gas and solid / gas and liquid. With its advantages of compact structure, high thermal intensity, controllable residence time, and high processing efficiency, it is widely used in hazardous waste incineration, biomass gasification, solid waste melting treatment, catalyst calcination, and metallurgical pretreatment.

[0003] Currently, traditional cyclone furnaces can be mainly divided into two categories: tangential air intake type and axial air intake type. Their heat source supply method is mostly internal combustion type, that is, fuel and combustion air are directly introduced into the furnace for combustion, and the combustion flame is in direct contact with the material. The material is heated by high temperature flue gas and furnace wall radiation.

[0004] However, ordinary vertical external heating cyclone furnaces often have some problems in daily use. With the development of technology, technicians in related fields have also made a lot of optimizations to vertical external heating cyclone furnaces to solve some of the problems that different consumer groups are concerned about. For a more accurate comparison, Chinese patent publication number CN221484175U discloses a far-infrared heating furnace that facilitates feeding, including a first feeding structure, a second feeding structure, and a far-infrared heating furnace. The first feeding structure is fixedly connected to one side of the far-infrared heating furnace, and the second feeding structure is fixedly connected to the side of the far-infrared heating furnace opposite to the first feeding structure. The above-mentioned prior art is a far-infrared heating furnace that facilitates feeding. By installing the first feeding structure, the second feeding structure, and the far-infrared heating furnace, it is convenient to carry out the material guiding and discharging work. The far-infrared heating furnace performs centralized infrared heating treatment. The first feeding structure and the second feeding structure are symmetrically arranged, which facilitates the feeding and discharging of materials and helps to achieve uniform production processing.

[0005] However, the aforementioned far-infrared heating furnace, which facilitates material feeding, still has some shortcomings in practical use: 1. The far-infrared heating furnace mentioned above, which facilitates material feeding, facilitates material handling by installing a first feeding structure, a second feeding structure, and a far-infrared heating furnace. However, the material will come into contact with the outside world during the transmission process, which will cause the material to be contaminated, thereby reducing the heating quality.

[0006] 2. The far-infrared heating furnace mentioned above, which facilitates material feeding, performs centralized infrared heating treatment. However, the material is in a static state during the heating process, resulting in uneven heating and reduced heating efficiency.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing vertical external heating cyclone furnaces and methods. Summary of the Invention

[0032] The following is in conjunction with the appendix Figures 1 to 9 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0033] This application discloses a vertical external heating cyclone furnace. It is described that this application is mainly used in the heating process of materials. In terms of technical effect, it can uniformly blow materials into the cyclone furnace with nitrogen, so that the materials are boiled and rotated on the inner wall of the cyclone furnace and heated evenly. In particular, it can automatically control the rotation and heating time of the materials in the cyclone furnace during material heating, so that the materials can be heated to a suitable temperature. Furthermore, this application can also screen the heated materials, so that the materials are cooled separately, thereby improving the cooling efficiency of the materials.

[0034] Example 1: Refer to Figure 1 As shown, the vertical externally heated cyclone furnace includes a frame 1, a partition 10, a slag collection chamber 11, a heating furnace 12, a nitrogen generator output pipe 13, a screw feeder 14, a feed hopper 15, a belt scale 16, a circulation mechanism 2, a screening mechanism 3, and a transmission pipe 17. The inner wall of the frame 1 is provided with a partition 10, and the slag collection chamber 11 is located between the partition 10 and the inner wall of the frame 1. The slag collection chamber 11 is used to store impurities in the material. The heating furnace 12 is located on one side of the partition 10 and within the slag collection chamber 11, and is used to heat the material. The nitrogen generator output pipe 13 is located on the side of the heating furnace 12 away from the partition 10. The nitrogen generator output pipe 13 is used to transfer nitrogen generated by the nitrogen generator to the heating furnace 12, and the nitrogen transfer can move the material in the nitrogen generator output pipe 13 together. A screw feeder 14 is located at the top of the nitrogen generator output pipe 13, and a feed hopper 15 is located at the end of the screw feeder 14 away from the nitrogen generator output pipe 13. When the material enters the feed hopper 15, it falls into the screw feeder 14. The rotation of the screw feeder 14 drives the material into the nitrogen generator output pipe 13. A belt scale 16 is installed on one side of the top of the feed hopper 15 via a bracket. The belt scale 16 is used to weigh the material entering the feed hopper 15. The weighed material will then enter the feed hopper 15. A circulation mechanism 2 is installed inside the heating furnace 12. The circulation mechanism 2 is used to automatically control the time when the material is heated in the cyclone furnace, so that the material can be heated to a suitable temperature. A screening mechanism 3 is installed on the top of the frame 1. The screening mechanism 3 is used to screen the heated material, so that the material is cooled separately, thereby improving the cooling efficiency of the material. The heating furnace 12 and the screening mechanism 3 are connected by a transmission pipe 17. The heated material in the heating furnace 12 can enter the screening mechanism 3 through the transmission pipe 17.

[0035] In the specific implementation process, the material is first weighed by the belt 360 and then falls into the feed hopper 15. When the material enters the feed hopper 15, it falls into the screw feeder 14. The rotation of the screw feeder 14 will drive the material into the nitrogen generator output pipe 13. At the same time, the nitrogen generated by the nitrogen generator is transferred to the heating furnace 12 through the nitrogen generator output pipe 13. During the transfer of nitrogen, the material in the nitrogen generator output pipe 13 will also enter the heating furnace 12. Then, the material is heated by the heating furnace 12. The circulation mechanism 2 can automatically control the rotation and heating time of the material in the cyclone furnace during the heating process, so that the material can be heated to a suitable temperature. The heated material in the heating furnace 12 can enter the screening mechanism 3 through the transmission pipe 17. The screening mechanism 3 is used to screen the heated material, so that the material is cooled separately, thereby improving the cooling efficiency of the material.

[0036] Reference Figure 2 As shown, this is the circulation mechanism 2 in this application; specifically, the circulation mechanism 2 includes a stop block 20, a rotating shaft 21, a rotating plate 22, a circular hole 220, a pressure plate 23, a fixed plate 230, and a spring 231. A stop block 20 is provided at the center of the inner wall of the heating furnace 12, and the nitrogen gas transmitted to the heating furnace 12 will drive the material to circulate along the stop block 20; a rotating shaft 21 is rotatably provided through the center of the top of the stop block 20 and can rotate under the restriction of the stop block 20; a rotating plate 22 is sleeved on the rotating shaft 21 and located inside the heating furnace 12. When the rotating shaft 21 rotates, it can drive the rotating plate 22 to rotate together; the rotating plate 22 has multiple round holes 220, and the nitrogen gas entering the heating furnace 12 can continue to circulate through the round holes 220 during the circulation process; a pressure plate 23 is provided on the rotating shaft 21 and outside the heating furnace 12, and the rotating shaft 21 can drive the pressure plate 23 to rotate together; a fixed plate 230 is provided on the outer wall of the heating furnace 12, and a spring 231 is provided between the fixed plate 230 and the pressure plate 23. The spring 231 can always provide the pressure plate 23 with a tension close to the fixed plate 230.

[0037] In the specific implementation process, when the material and nitrogen enter the heating furnace 12, the nitrogen transmitted to the heating furnace 12 will drive the material to circulate along the baffle 20. When the material comes into contact with the rotating plate 22, it will drive the rotating plate 22 to rotate. When the rotating plate 22 rotates, it can drive the rotating shaft 21 to rotate together. When the rotating shaft 21 rotates, it can drive the pressure plate 23 to rotate together. When the rotating plate 22 rotates to a certain angle, the material slides off the rotating plate 22 and continues to rotate along the baffle 20. The rotating plate 22 and the pressure plate 23 are reset under the action of the spring 231, waiting for the next contact with the material.

[0038] Reference Figure 3As shown, this is the circulation mechanism 2 in this application; specifically, the circulation mechanism 2 also includes a strip plate 24, an arc-shaped triangular block 240, a spring 241, a baffle 25, a connecting rod 26, an arc-shaped triangular block 250, a clamping plate 27, a spring 270, a linkage unit 28, and a delay unit 29. The strip plate 24 is slidably arranged on the outer wall of the heating furnace 12, and the strip plate 24 can slide under the restriction of the outer wall of the heating furnace 12; multiple arc-shaped triangular blocks 240 are arranged on the side of the strip plate 24 near the pressure plate 23, and a spring 241 is arranged between the arc-shaped triangular blocks and the strip plate 24. The spring 241 can always provide a pushing force to the arc-shaped triangular blocks 240 near the pressure plate 23. When the strip plate 24 moves, it can drive the spring 241 and the arc-shaped triangular blocks 240 to move together; a baffle 25 is slidably arranged on the top of the heating furnace 12, and the baffle 25 can slide down under the restriction of the heating furnace 12. The baffle 25 and the strip plate 24 are connected by a connecting rod 26. When the strip plate 24 moves, it can drive the connecting rod 26 to move together, and when the connecting rod 26 moves, it can drive the baffle 25 to move together. Multiple arc-shaped triangular blocks 250 are provided on the side of the baffle 25 near the strip plate 24. When the baffle 25 moves, it can also drive the arc-shaped triangular blocks 250 to move together. A clamping plate 27 is rotatably provided on the top of the heating furnace 12. When the clamping plate 27 abuts against the arc-shaped triangular blocks 250, it will restrict the movement of the strip plate 24. A spring 3 270 is provided at the bottom of the clamping plate 27. The spring 3 270 can always provide a force to keep the clamping plate 27 horizontal. A linkage unit 28 is provided on the side of the strip plate 24 away from the clamping plate 27. The linkage unit 28 is used to control the on and off of the transmission pipe 17. A delay unit 29 is provided on the top of the heating furnace 12. The delay unit 29 is used to control the baffle 25 to slowly reset upward.

[0039] In the specific implementation process, when the rotating shaft 21 drives the pressure plate 23 to rotate, the pressure plate 23 will abut against the arc-shaped triangular block 240 and push the arc-shaped triangular block 240 to move downward. When the arc-shaped triangular block 240 moves downward, it can drive the strip plate 24 to move together. When the strip plate 24 moves, it can drive the connecting rod 26 to move together. When the connecting rod 26 moves, it can drive the baffle 25 to move downward together. When the baffle 25 moves downward, it will drive the arc-shaped triangular block 250 to move together. When the arc-shaped triangular block 250 moves, it will drive the clamping plate 27 to rotate downward. When the clamping plate 27 moves between the arc-shaped triangular blocks 250, the clamping plate 27 abuts against the arc-shaped triangular block below under the action of the spring 270, preventing the baffle 25 from resetting. After repeating this cycle several times, the baffle 25 will abut against the stop block 20, thereby cutting off the rotation of the material. During this process, the connection of the transmission pipe 17 is opened through the linkage unit 28, so that the material enters the transmission pipe 17.

[0040] Reference Figure 4As shown, this is the linkage unit 28 in this application; specifically, the linkage unit 28 includes a slide rail 280, a spur gear 281, a rack 282, a sealing plate 283, an L-shaped plate 284, a Z-shaped plate 285, an extension plate 286, and a spring 287. Slide rails 280 are symmetrically arranged on the top of the heating furnace 12. A spur gear 281 is rotatably arranged on the top of the heating furnace 12 and located between the slide rails 280. Racks 282, meshing with the spur gear 281, are alternately slidably arranged within the slide rails 280. The racks 282 can slide within the slide rails 280. When one rack 282 moves, it can drive the spur gear 281 to rotate; when the spur gear 281 rotates, it can drive the other rack 282 to move. A sealing plate that abuts against the transmission pipe 17 is slidably arranged on the top of the heating furnace 12. Plate 283, sealing plate 283 is used to block the feed inlet of the transmission pipe 17; one rack 282 is connected to baffle 25 through L-shaped plate 284, when baffle 25 moves it can drive L-shaped plate 284 to move together, when L-shaped plate 284 moves it can drive rack 282 connected to it to move together; another rack 282 is connected to sealing plate 283 through Z-shaped plate 285, when the other rack 282 moves it can drive Z-shaped plate 285 to move together, when Z-shaped plate 285 moves it can drive sealing plate 283 to move together; an extension plate 286 is provided at the bottom slide 280 of L-shaped plate 284, and a spring 287 is provided between extension plate 286 and L-shaped plate 284, the spring 287 can always provide upward thrust to L-shaped plate 284.

[0041] In the specific implementation process, when the baffle 25 moves, it can drive the L-shaped plate 284 to move together. When the L-shaped plate 284 moves, it can drive the rack 282 connected to it to move together. When the rack 282 moves, it can drive the spur gear 281 to rotate. When the spur gear 281 rotates, it can drive another rack 282 to move in the opposite direction. When the other rack 282 moves in the opposite direction, it can drive the Z-shaped plate 285 to move together. When the Z-shaped plate 285 moves, it can drive the sealing plate 283 to move together, thereby controlling the position of the sealing plate 283, and thus controlling the on / off of the transmission pipe 17.

[0042] Reference Figure 5As shown, this is the delay unit 29 in this application; specifically, the delay unit 29 includes a rotating cylinder 290, a rotating plate 291, a T-shaped rod 292, a counterweight column 293, a square pipe 294, and a connecting groove 295. The rotating cylinder 290 is rotatably mounted on the top of the heating furnace 12, and the rotating plate 291 is mounted on the outer wall of the rotating cylinder 290. When the rotating cylinder 290 rotates, it can drive the rotating plate 291 to rotate together. The T-shaped rod 292 is mounted on the bottom of the rotating cylinder 290. When the T-shaped rod 292 shakes, it can drive the rotating cylinder 290 to shake together. The two sides of the T-shaped rod 292 are symmetrical. A counterweight column 293 is provided, which allows the T-shaped rod 292 to sway. A square pipe 294 is directly inclined between one of the counterweight columns 293 and the top of the heating furnace 12, and a strip plate 24 slides through the square pipe 294. A baffle 25 has multiple connecting slots 295 that cooperate with the square pipe 294. When the baffle 25 moves to a suitable position, the nitrogen gas in the heating furnace 12 can be blown towards the counterweight column 293 along the square pipe 294 and the connecting slots 295, thereby causing the T-shaped rod 292 and the counterweight column 293 to sway.

[0043] In the specific implementation process, when the baffle 25 abuts against the stop block 20, the pressure inside the heating furnace 12 near the transmission pipe 17 increases, and the square pipe 294 connects to the connecting groove 295, allowing nitrogen gas to enter the square pipe 294 and the connecting groove 295. This allows the nitrogen gas to blow towards the counterweight column 293 and push the counterweight column 293 to rotate. When the counterweight column 293 rotates, it drives the T-shaped rod 292 to rotate as well. When the T-shaped rod 292 rotates, it drives the rotating drum 290 to rotate as well. When the rotating drum 290 rotates, it drives the rotating plate 291 to rotate as well. When the rotating plate 291 rotates, it will... The plate 27 contacts the side away from the arc-shaped triangular block 250, causing the plate 27 to rotate upward. After the plate 27 rotates, it no longer contacts the top of the arc-shaped triangular block 250, thus causing the baffle 25 to move upward a certain distance under the action of the spring 287. During the upward movement of the baffle 25, the directional pipe and the connecting groove 295 are no longer connected, causing the counterweight column 293 and the T-shaped rod 292 to reset, which in turn causes the rotating cylinder 290 and the rotating plate 291 to reset. The rotating plate 291 contacts the top of the next arc-shaped triangular block 250, realizing the slow rise of the baffle 25.

[0044] Reference Figure 6As shown, this is the screening mechanism 3 in this application; specifically, the screening mechanism 3 includes hollow plates 30, material collection bins 31, buffer bins 32, gate valves 33, and screening pipes 34. Multiple hollow plates 30 are symmetrically arranged at the top of the frame 1, and the interior of each hollow plate 30 is filled with coolant for rapid cooling of the material in the material collection bins 31. Material collection bins 31 are arranged between the hollow plates 30, and the material in the heating furnace 12 can enter the material collection bins 31 through the transmission pipes 17. Buffer bins 32 are arranged at the bottom of the material collection bins 31 for storing the cooled material. The material is collected in the buffer chamber 32. The upper and lower sides of the buffer chamber 32 are symmetrically equipped with gate valves 33. After the material in the material collection chamber 31 has cooled down, the upper gate valve 33 is opened first to allow the cooled material to enter the buffer chamber 32. Then the upper gate valve 33 is closed and the lower gate valve 33 is opened to allow the material in the buffer chamber 32 to fall. After the material in the buffer chamber 32 has been discharged, the lower gate valve 33 is closed again. The material collection chambers 31 are connected by a hollow plate 30 and a screening pipe 34. The material in the material collection chamber 31 can enter the other material collection chamber 31 through the screening pipe 34.

[0045] In the specific implementation process, the material in the heating furnace 12 can enter the material collection bin 31 through the transmission pipe 17. The material in the material collection bin 31 is quickly cooled by the coolant filled inside the hollow plate 30. After the material in the material collection bin 31 is cooled, the upper gate valve 33 is opened first to allow the cooled material to enter the buffer bin 32. Then the upper gate valve 33 is closed and the lower gate valve 33 is opened to allow the material in the buffer bin 32 to fall. After the material in the buffer bin 32 is discharged, the lower gate valve 33 is closed again.

[0046] Reference Figure 7As shown, this is the screening mechanism 3 in this application; specifically, the screening mechanism 3 also includes a V-shaped plate 35, a screening hole 350, a drive wheel 36, a belt 360, a guide wheel 361, a transfer bucket 37, a transmission rod 38, and a fan blade 39. A V-shaped plate 35 is provided on the inner wall of the material collection bin 31, located at the inlet of the screening pipe 34. Screening holes 350 are provided on the V-shaped plate 35, allowing materials to enter the corresponding material collection bin 31 through the size of the screening holes 350. Drive wheels 36 are symmetrically rotatably arranged on the inner wall of the material collection bin 31, connected by a belt 360. When the drive wheels 36 rotate, they drive the belt 360 to rotate. The inner wall of the material collection bin 31 and the belt 360 are connected by a belt 360. The belt 360 is symmetrically arranged with guide wheels 361, which are used to change the transmission direction of the belt 360. Multiple transfer buckets 37 are rotatably arranged along the outer wall of the belt 360. When the belt 360 rotates, it can drive the transfer buckets 37 to move together. The transfer buckets 37 are used to move the material. A transmission rod 38 is arranged between the drive wheels 36 at the bottom. Multiple fan blades 39 are evenly arranged along the circumference of the transmission rod 38 and at the discharge end of the transmission pipe 17. When the material is being transported, nitrogen is also transported at the discharge end of the transmission pipe 17. The nitrogen can be blown onto the fan blades 39, thereby driving the transmission rod 38 to rotate through the fan blades 39. When the transmission rod 38 rotates, it can drive the drive wheels 36 to rotate together.

[0047] One point to note is that the further away from the heating furnace 12 the smaller the screening holes 350 are, thus achieving the purpose of screening.

[0048] In the specific implementation process, nitrogen gas is also transmitted at the discharge end of the transmission pipe 17 when the material is being transmitted. The nitrogen gas can be blown onto the fan blade 39, thereby driving the transmission rod 38 to rotate through the fan blade 39. When the transmission rod 38 rotates, it can drive the drive wheel 36 to rotate as well. When the drive wheel 36 rotates, it can drive the belt 360 to rotate. When the belt 360 rotates, it can drive the transfer bucket 37 to move together. At the same time, the material transmitted in the transmission pipe 17 will fall into the transfer bucket 37. The transfer bucket 37 is used to move the material. When the transfer bucket 37 moves along the belt 360, it tilts, thereby pouring the material in the transfer bucket 37 onto the V-shaped plate 35 and entering the screening pipe 34 through the screening hole 350. The material in the screening pipe 34 will enter another material collection bin 31.

[0049] Example 2: Refer to Figure 8 As shown, based on Embodiment 1, in order to enable centralized discharge and facilitate centralized collection by operators, in this specific embodiment of the solution, a spiral discharger 4 is provided at the bottom of the buffer bin 32, and a discharge hopper 40 is provided at the bottom of the spiral discharger 4. All materials leaking out of the buffer bin 32 will enter the spiral discharger 4, and the materials in the spiral discharger 4 will enter the discharge hopper 40.

[0050] Reference Figure 9As shown, a filter screen 5 is provided at the bottom of the inner wall of the heating furnace 12 in this application. Impurities in the heating furnace 12 will fall into the top of the circular block plate 52 through the filter screen 5. An installation block 50 is provided on the outer wall of the bottom of the heating furnace 12. An installation frame 51 is rotatably provided at the bottom of the installation block 50. A circular block plate 52 is provided on the other side of the installation frame 51, which abuts against the bottom of the heating furnace 12. When the impurities on the top of the circular block plate 52 reach a certain weight, the circular block plate 52 and the installation frame 51 rotate under the restriction of the installation block 50, so that the circular block plate 52 rotates and the impurities fall into the slag collection chamber 11. The installation block 50 and the installation frame 51 are connected by a spring 53. The spring 53 can always provide an upward pulling force to the installation frame 51.

[0051] During operation: First, the material is weighed by the belt conveyor 360 and falls into the feed hopper 15. When the material enters the feed hopper 15, it will fall into the screw feeder 14. The rotation of the screw feeder 14 will drive the material into the nitrogen generator output pipe 13. At the same time, the nitrogen generated by the nitrogen generator is transmitted to the heating furnace 12 through the nitrogen generator output pipe 13. When the nitrogen is transmitted, it can also drive the material in the nitrogen generator output pipe 13 into the heating furnace 12.

[0052] Step 2: When the material and nitrogen enter the heating furnace 12, the nitrogen transferred into the heating furnace 12 will cause the material to circulate along the baffle 20. When the impurities on the top of the circular block 52 reach a certain weight, the circular block 52 and the mounting bracket 51 will rotate under the restriction of the mounting block 50, causing the circular block 52 to rotate and the impurities to fall into the slag collection chamber 11. At the same time, when the material comes into contact with the rotating plate 22, it will drive the rotating plate 22 to rotate. When the rotating plate 22 rotates, it will drive the rotating shaft 21 to rotate together. When the rotating shaft 21 rotates, it will drive the pressure plate 23 to rotate together. When the pressure plate 23 rotates, the pressure plate 23 will come into contact with the arc-shaped triangular block 240 and push the arc-shaped triangular block 240. Corner block 240 moves downwards. When the arc-shaped triangular block 240 moves downwards, it drives the strip plate 24 to move together. When the strip plate 24 moves, it drives the connecting rod 26 to move together. When the connecting rod 26 moves, it drives the baffle 25 to move downwards together. When the baffle 25 moves downwards, it drives the arc-shaped triangular block 250 to move together. When the arc-shaped triangular block 250 moves, it drives the clamping plate 27 to rotate downwards. When the clamping plate 27 moves between the arc-shaped triangular blocks 250, the clamping plate 27, driven by the spring 270, abuts against the arc-shaped triangular block below, preventing the baffle 25 from resetting. After repeating this cycle several times, the baffle 25 will abut against the stop block 20, thereby cutting off the rotation of the material.

[0053] Step 3: When the baffle 25 moves, it can drive the L-shaped plate 284 to move together. When the L-shaped plate 284 moves, it can drive the rack 282 connected to it to move together. When the rack 282 moves, it can drive the spur gear 281 to rotate. When the spur gear 281 rotates, it can drive another rack 282 to move in the opposite direction. When the other rack 282 moves in the opposite direction, it can drive the Z-shaped plate 285 to move together. When the Z-shaped plate 285 moves, it can drive the sealing plate 283 to move together, so that the material can enter the transmission pipe 17.

[0054] Step 4: When the baffle 25 contacts the stop block 20, the pressure inside the heating furnace 12 near the transmission pipe 17 increases, and the square pipe 294 connects to the connecting groove 295, allowing nitrogen to enter the square pipe 294 and the connecting groove 295. This allows the nitrogen to blow towards the counterweight column 293, pushing it to rotate. The rotation of the counterweight column 293 causes the T-shaped rod 292 to rotate as well. The rotation of the T-shaped rod 292 causes the rotating drum 290 to rotate as well. The rotation of the rotating drum 290 causes the rotating plate 291 to rotate as well. During rotation, the rotating plate 291 will contact the clamping plate... 27 is away from the side of the arc-shaped triangular block 250 and drives the clamping plate 27 to rotate upward. After the clamping plate 27 rotates, it no longer touches the top of the arc-shaped triangular block 250, so that the baffle 25 moves upward a certain distance under the action of the spring 4 287. During the upward movement of the baffle 25, the directional pipe and the connecting groove 295 are no longer connected, so that the counterweight column 293 and the T-shaped rod 292 are reset, and then the rotating cylinder 290 and the rotating plate 291 are reset. The rotating plate 291 touches the top of the next arc-shaped triangular block 250, so that the baffle 25 rises slowly.

[0055] Step 5: Nitrogen gas is also transmitted at the discharge end of the transmission pipe 17 while the material is being transported. The nitrogen gas is blown onto the fan blades 39, which in turn drive the transmission rod 38 to rotate. The rotation of the transmission rod 38 drives the drive wheel 36 to rotate, which in turn drives the belt 360 to rotate. The rotation of the belt 360 drives the transfer bucket 37 to move. At the same time, the material being transported in the transmission pipe 17 falls into the transfer bucket 37. The transfer bucket 37 is used to move the material. As the transfer bucket 37 moves along the belt 360, it tilts, thus pouring the material in the transfer bucket 37 onto the V-shaped plate 35 and into the screening hole 350. The material enters the screening pipe 34 and then enters another material collection chamber 31 to screen the heated material. The material in the collection chamber 31 is then cooled quickly by the coolant filled inside the hollow plate 30. After the material in the collection chamber 31 has cooled down, the upper gate valve 33 is opened to allow the cooled material to enter the buffer chamber 32. Then the upper gate valve 33 is closed and the lower gate valve 33 is opened to allow the material in the buffer chamber 32 to fall. After the material in the buffer chamber 32 has been discharged, the lower gate valve 33 is closed again to allow the material to be cooled separately, thereby improving the cooling efficiency of the material.

[0056] Step 6: All materials leaking out of the buffer chamber 32 will enter the screw conveyor 4, and the materials in the screw conveyor 4 will enter the discharge hopper 40, achieving centralized discharge and facilitating centralized collection by operators.
