Description

Technical Field

[0001] This invention belongs to the field of cooling equipment, and specifically relates to a counter-flow particle cooler with uniform material distribution. Background Technology

[0002] Counter-flow coolers are widely used cooling equipment in the feed, grain, oil, and biomass pellet production industries. Their working principle involves counter-current heat exchange between cold air and hot pellet material in a vertical direction—the material moves from top to bottom, while the cold air flows from bottom to top through the material layer, thus carrying away heat and moisture from the pellets. Compared to traditional co-current cooling, counter-current cooling has advantages such as higher heat exchange efficiency and relatively lower energy consumption, thus dominating large and medium-sized pellet material production lines.

[0003] In the structure of a counter-flow cooler, the material distribution device located at the top of the cooling chamber is one of the core components determining the cooling effect. After the particulate material enters the cooler through the feed inlet, it needs to be evenly distributed across the entire cross-section of the cooling chamber by the material distribution device to form a material layer of uniform thickness. A uniform material layer ensures that the air resistance is evenly distributed when the cold air passes through the material, thereby achieving sufficient and uniform heat exchange between the gas and solid phases.

[0004] However, uneven material distribution has been a long-standing technical challenge for the counter-flow cooler industry. Existing material distribution devices mainly fall into two categories: one is a four-sided cone spreader, where material slides down the cone surface into the cooling chamber. However, this method easily leads to uneven material accumulation around the cone, and a thick localized layer of material tends to form at the cone's edge. The other is a rotating material distributor, which uses a rotating throwing or spreading disc to centrifugally throw out the material. Although this method covers a larger area, it is still difficult to achieve uniform coverage throughout the entire circumference due to factors such as material flow fluctuations, particle size differences, and equipment wear.

[0005] Uneven material distribution directly results in inconsistent material layer heights within the cooling chamber. In areas with thinner layers, airflow resistance is low and wind speed is high, making it prone to "blow-through" or void phenomena under airflow impact, leading to short-circuiting of the cold air. Conversely, in areas with thicker layers, airflow resistance is high and wind speed is low, resulting in insufficient particle cooling. This difference in airflow distribution ultimately leads to inconsistent cooling levels within the same batch of material—some particles are over-cooled with low moisture content, while others remain in a high-temperature, high-humidity state. This not only affects the uniformity of product quality but, in severe cases, can also cause mold growth due to residual heat after bagging, resulting in economic losses. Therefore, achieving uniform and stable material distribution during the feeding process of a counter-flow cooler has become a critical technical problem urgently needing to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a counter-flow particle cooler with uniform material distribution, so as to achieve circumferential uniform material distribution, layered uniform material distribution and uniform cooling air penetration in the cooler, thereby improving cooling efficiency and product quality consistency.

[0007] The objective of this invention is achieved as follows: A counter-current particle cooler with uniform material distribution includes a support frame, a discharge cylinder mounted on the support frame, a vertical cooling shell mounted on the upper side of the discharge cylinder, the cooling shell being connected to the interior of the discharge cylinder, the cooling shell being fixed to the support frame, a feed inlet mounted on the upper side of the cooling shell, an anti-stacking mechanism mounted on the cooling shell corresponding to the feed inlet, a vertical central rotating shaft mounted inside the cooling shell, the upper end of the central rotating shaft being connected to a rotating drive mechanism, a circumferential material distribution mechanism mounted on the upper part of the central rotating shaft corresponding to the feed inlet, and a feed distribution mechanism located inside the cooling shell. The cooling housing consists of three horizontally rotating material support layers arranged from top to bottom: a first rotating material support layer, a second rotating material support layer, and a third rotating material support layer. A uniform material distribution mechanism is positioned above the first rotating material support layer, and a uniform material distribution mechanism is positioned above the second rotating material support layer. A central rotating shaft passes downwards through the first and second rotating material support layers. A sweeping component is located at the lower end of the central rotating shaft, positioned above the third rotating material support layer. The bottom of the discharge cylinder has a discharge port, and the top of the cooling housing has a suction cylinder connected to the interior of the cooling housing. The upper end of the suction cylinder is connected to a blower.

[0008] The working process of this invention is as follows: (1) Feeding and preventing material accumulation: The material enters from the feeding cylinder, and the dispersing motor drives the dispersing rod to rotate at high speed to disperse the material and prevent bridging; (2) Circumferential material distribution: The material falls into the rotating drum through the guide cylinder. The drive motor drives the central rotating shaft and the rotating drum to rotate simultaneously. Under the action of centrifugal force, the material is evenly distributed from each inclined discharge cylinder to the periphery of the cooling shell. (3) Layer-by-layer spreading and cooling: The material falls onto the first and second flipped material layers in sequence. The uniform material distribution mechanism above each layer moves back and forth, and the material is continuously spread by the material distribution rod. At the same time, the air outlet blows cooling air into the material layer. The exhaust fan draws air from the top, and the bottom opening of the discharge cylinder sends air into the cooler through the air supply and cooling device. The cold air passes through the ventilation micro-holes on each flipped material layer from bottom to top and exchanges heat with the material in a countercurrent manner, taking away the heat and moisture of the material. The material on the first and second flipped material layers simultaneously receives air blown from the air outlet from top to bottom and cold air passing through the ventilation micro-holes from bottom to top, which greatly improves the cooling effect. (4) Layered unloading: After the material is cooled by the first and second flipping material layers, the driving cylinders of each flipping material layer are activated in sequence to drive each flipping material plate to flip, and the material falls layer by layer to the next layer until it falls on the third flipping material layer. (5) Sweeping and discharging: The sweeping component rotates with the central rotating shaft to sweep the material on the third flipping material layer evenly. Then the flipping material plate of the third flipping material layer flips to send the material to the fourth flipping material layer. The fourth flipping material layer in the discharge cylinder serves as a buffer unloading layer and receives cold air flowing from bottom to top for cooling. Finally, the cooled material is discharged from the discharge port of the discharge cylinder.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting an anti-stacking mechanism (dispersing rod), the particulate material that may bridging or arching is pre-dispersed at the feed inlet, effectively avoiding material blockage at the feed inlet and ensuring the continuity and stability of feeding. 2. By setting a circumferential material distribution mechanism (rotating drum and circumferentially distributed inclined discharge drum), centrifugal force is used to evenly distribute the material around the cooling shell in the circumferential direction, achieving preliminary uniform distribution of the material in the horizontal cross section, avoiding the problem of conical accumulation of material directly below the feed inlet in traditional feeding methods. 3. By setting up two layers of uniform material distribution mechanisms (corresponding to the first and second flipping material support layers respectively), the reciprocating bellows drive the material distribution rods to move and flatten the material layer. Simultaneously, an air outlet is installed under the bellows to blow cooling air onto the material layer while distributing the material, achieving integrated "distribution and cooling" operations. This significantly improves the uniformity of material distribution and cooling efficiency. Combined with the upward flow of cold air through the ventilation micro-holes on each flipping material support layer, convection cooling is achieved. 4. The flipping material support plates adopt a "lap joint + lap surface" mating structure, forming a labyrinthine seal between adjacent flipping material support plates, effectively preventing fine powder materials from leaking from the gaps between the plates. Furthermore, each flipping material support plate rotates in conjunction with a support shaft and a swing arm, ensuring synchronized and reliable unloading. 5. By setting three layers of tilting material support within the cooling shell and a fourth tilting material support within the discharge cylinder, the material forms multiple layers within the cooler. Cooling air enters from the bottom and passes sequentially through the ventilation micropores on each tilting material support plate, achieving thorough heat exchange with the material. This counter-current cooling effect is excellent, and energy consumption is low. 6. The sweeping assembly rotates with the central axis, sweeping the material on the third tilting material support along the circumferential direction. The first and second tilting material support layers sweep the material longitudinally and laterally, respectively, ensuring uniform material distribution and more thorough cooling. The overall structure of this invention is compact, with a reasonable layout of functional modules, a high degree of automation, and is suitable for large-scale industrial production.

[0010] As a further improvement of the present invention, the support frame includes four horizontal side beams forming a ring, and four columns located at each corner are correspondingly arranged on the lower side of each side beam. A side reinforcing beam is provided between any two adjacent left and right columns. The side reinforcing beams enhance the overall rigidity and stability of the support frame.

[0011] As a further improvement of the present invention, the discharge cylinder has a rectangular cross-section in the horizontal direction, and the flow area of ​​the discharge cylinder decreases from top to bottom. The discharge cylinder includes four cylinder side plates, which are inclined. The upper and lower ends of the four cylinder side plates form a rectangle, and the upper side of the four cylinder side plates are respectively fixed to four side main beams. The cooling shell includes a main body section, and a top shell section is provided on the upper part of the main body section. The cross-section of the main body section and the top shell section are both rectangular in the horizontal direction. The side walls of the main body section of the cooling shell are vertical, and the side walls of the top shell section of the cooling shell are inclined. The flow area of ​​the top shell section of the cooling shell increases from top to bottom. A side base plate is provided on the upper side of each side main beam, and a reinforcing support plate is fixed on the inner side of each side main beam. Each reinforcing support plate supports the corresponding side base plate. The lower parts of the four side walls of the main body section of the cooling shell are respectively fixed to the four side base plates. The flow area of ​​the discharge cylinder decreases from top to bottom, forming an inverted truncated pyramid shape. The lower part of the four side walls of the main body of the cooling shell is fixed to the four side base plates, thereby firmly installing the cooling shell on the support frame 1. The lower opening of the cooling shell is connected to the upper opening of the discharge cylinder. In order to increase the area of ​​the cooling shell, the reinforcing support plate and side base plates can be omitted, so that the four side walls of the main body of the cooling shell can be directly fixed to the four side main beams.

[0012] As a further improvement of the present invention, the feed inlet is located at the top of the top shell section of the cooling shell. The anti-stacking mechanism includes a feed cylinder disposed on the upper side of the top shell section of the cooling shell, with the feed cylinder corresponding to the feed inlet. A transverse rotating shaft is rotatably disposed inside the feed cylinder, with one end of the transverse rotating shaft extending out of the feed cylinder and connected to a dispersing motor. Multiple dispersing rods are mounted on the outer periphery of the transverse rotating shaft. A guide cylinder is disposed inside the cooling shell corresponding to the feed inlet. When particulate material enters from above the feed cylinder, the dispersing motor drives the transverse rotating shaft and the dispersing rods to rotate at high speed, dispersing any material that may clump or bridge. The guide cylinder guides the material to fall accurately into the rotating cylinder. The dispersing rods can also be replaced by dispersing blades, etc.

[0013] As a further improvement of the present invention, the central rotating shaft is located in the middle of the cooling shell. The rotating drive mechanism includes a drive motor vertically mounted on the top of the cooling shell via a bracket, with the output end of the drive motor facing downwards. The upper end of the central rotating shaft extends out of the cooling shell and is connected to the drive motor for transmission. The circumferential material distribution mechanism includes a vertical rotating cylinder coaxial with the central rotating shaft. The upper end of the rotating cylinder is open and corresponding to the guide cylinder. The central rotating shaft passes through the bottom of the rotating cylinder and is fixedly connected to it. Inside the rotating cylinder, there are several radial connecting rods distributed circumferentially around the central rotating shaft. The inner and outer ends of the connecting rods are fixed to the central rotating shaft and the inner wall of the rotating cylinder, respectively. Several inclined discharge cylinders are evenly distributed circumferentially around the outer circumference of the rotating cylinder, and the discharge cylinders are connected to the interior of the rotating cylinder. The discharge direction of the discharge cylinders is inclined outwards and downwards. When the drive motor drives the central rotating shaft and the rotating cylinder to rotate at high speed, the material is evenly thrown from each discharge cylinder to the periphery of the cooling shell under the action of centrifugal force, achieving uniform circumferential material distribution.

[0014] As a further improvement of the present invention, the flipping material support layer includes a plurality of flipping material support plates arranged laterally. The flipping material support plates are arranged longitudinally, with an inclined overlapping portion on the left side and an inclined overlapping surface on the right side. The overlapping surface of each flipping material support plate corresponds to the overlapping portion of the adjacent flipping material support plate. At least two parallel reinforcing mounting plates are correspondingly arranged on the lower side of each flipping material support plate. The reinforcing mounting plates are also fixed to the overlapping portions. Each reinforcing mounting plate of each flipping material support plate is fixed to a longitudinal support shaft. The support shaft passes through each reinforcing mounting plate. One end of the support shaft passes through the side wall of the cooling housing and is rotatably connected to the cooling housing. A swing rod is vertically arranged at the extended end of the support shaft. The swing rod of each support shaft is driven by a swing drive mechanism. The other end of the support shaft is rotatably connected to the corresponding side wall of the cooling housing. Each flipping material support plate is evenly covered with open... The first flipping material support layer has several ventilation micro-holes, and a transverse clearance groove is opened through the corresponding flipping material support plate of the first flipping material support layer corresponding to the central rotation axis. The second flipping material support layer includes several longitudinally arranged flipping material support plates, which are arranged laterally. The structure of the second flipping material support plate is the same as that of the first flipping material support plate. Each reinforcing mounting plate of the second flipping material support plate is fixed to a transverse support shaft. The support shaft passes through each reinforcing mounting plate. One end of the support shaft passes through the side wall of the cooling shell and is rotatably connected to the cooling shell. A swing rod is vertically arranged at the extended end of the support shaft. The swing rod of each support shaft is connected to a swing drive mechanism. The other end of the support shaft is rotatably connected to the corresponding side wall of the cooling shell. Each flipping material support plate is covered with several ventilation micro-holes, and a longitudinal clearance groove is opened through the corresponding flipping material support plate of the second flipping material support layer corresponding to the central rotation axis. The third flipping material support layer has the same structure as the first flipping material support layer. Both the overlapping part and the overlapping surface have the same inclination angle, and a labyrinth-like sealing fit is formed between two adjacent flipping material support plates, which effectively prevents fine powder materials from leaking from the gaps between the plates; the diameter of the ventilation micro-holes is preferably 2-6mm, which can ensure that the cooling air passes through the material layer evenly and prevent material particles from leaking out of the micro-holes, and the clearance groove provides space for the central rotating shaft to pass through; the flipping directions of flipping material support layer one and flipping material support layer two are different to achieve layered unloading, the support shaft one of flipping material support layer one is set along the longitudinal direction, the support shaft two of flipping material support layer two is set along the transverse direction, and the support shaft of flipping material support layer three is set along the longitudinal direction.

[0015] As a further improvement of the present invention, the uniform fabric distribution mechanism includes two sets of fabric cooling assemblies symmetrically distributed on both sides of the central rotation axis. The fabric cooling assemblies are arranged longitudinally and include rectangular air boxes. A longitudinal lead screw is provided on the upper side of each air box inside the cooling housing. A longitudinal guide rod is provided on both the left and right sides of each longitudinal lead screw. The front and rear ends of the guide rods are respectively fixed to the inner walls of the front and rear sides of the cooling housing. One end of the lead screw is rotatably connected to the inner wall of the cooling housing, and the other end of the lead screw passes through the corresponding inner wall of the cooling housing and is driven by a moving motor. A transmission nut is threadedly connected to the lead screw. The transmission nut is connected to the corresponding air box via a transmission bracket. At least two guide seats with front and rear spacing are provided on the air box corresponding to each guide rod. The guide rod passes through the corresponding guide seats and is movably connected to them. The lower side of the air box is vertically... The system comprises several horizontally arranged air outlets connected to the interior of the air box. A horizontal mounting shaft is fixed inside each air outlet, and an adjustable rod is mounted on the mounting shaft. A brush head seat is located at the lower end of the adjusting rod, and several thin cloth rods are arranged on the lower side of the brush head seat. The thin cloth rods of the uniform cloth distribution mechanism one correspond to the flipping material support layer one. The outer diameter of the thin cloth rods is 2-4 mm. Each air box has an air inlet on its rear side, and an air inlet duct is provided on the rear side wall of the cooling shell corresponding to each air inlet. The inlet of the air inlet duct is connected to a blowing device, and a retractable corrugated rubber tube is provided between the outlet of the air inlet duct and the corresponding air inlet. The uniform cloth distribution mechanism two includes two sets of cloth cooling components symmetrically distributed on both sides of the central rotating shaft. The cloth cooling components of the uniform cloth distribution mechanism two are arranged horizontally, and the thin cloth rods of the uniform cloth distribution mechanism two correspond to the flipping material support layer two. When the moving motor drives the lead screw to rotate forward and backward, the transmission nut moves back and forth along the lead screw, thereby driving the bellows to move back and forth in the forward and backward direction. Each guide seat ensures the guiding accuracy and stability of the bellows during movement. The lower end of the material-laying rod is about 5-15mm away from the upper surface of the flipping material support plate to move the material layer without damaging the material particles. The outer diameter of the material-laying rod is preferably 3mm and it is made of wear-resistant stainless steel. The inlet of the air inlet is connected to the blowing device (such as a blower). The retractable corrugated rubber tube between the outlet of the air inlet and the corresponding air inlet can adapt to the expansion and contraction requirements of the air supply pipeline when the bellows moves back and forth. During operation, the bellows moves back and forth along the guide rod under the drive of the lead screw. The material-laying rod continuously moves and flattens the material layer below. At the same time, the cooling air blown out from the air outlet directly acts on the surface of the material layer, realizing the coordinated operation of material laying and cooling.

[0016] As a further improvement of the present invention, a sub-seat is provided on the inner walls of both the left and right sides of the air outlet duct. The mounting shaft is located between the two symmetrical sub-seats. The upper end of the adjusting rod is provided with a mounting ring, which is rotatably fitted onto the mounting shaft. The mounting ring has several circumferentially distributed connecting holes I. The sub-seats have several circumferentially distributed connecting holes II corresponding to each connecting hole I. Several connecting bolts pass through the connecting holes II of the corresponding sub-seats, the connecting holes I of the mounting ring, and the connecting holes II of another sub-seat in sequence. The ends of the connecting bolts are fitted with locking nuts that tighten the sub-seats. The lower end of the adjusting rod is provided with a ball head. The upper side of the brush head seat is provided with a ball cup that matches the ball head. The ball head of the adjusting rod is fitted into the ball cup of the brush head seat. The sweeping assembly includes a mounting bracket located at the lower end of the central rotating shaft. The lower side of the mounting bracket is provided with several sweeping rods spaced apart along the length direction. The sweeping rods are vertically arranged, and each sweeping rod is arranged corresponding to the flipping material support layer III. By loosening the connecting bolts, the adjusting rod can be rotated to the desired angle, and then the connecting bolts can be tightened again to change the tilt angle of the adjusting rod, thereby adjusting the position of the lower end of the fabric rod and the feeding angle to adapt to materials with different particle sizes and flowability. The ball-head-ball-bowl connection structure allows the brush head seat to adaptively adjust the angle, ensuring good contact between the fabric rod and the surface of the material layer. Even if the surface of the material layer is slightly uneven, the fabric rod can still fit well.

[0017] As a further improvement of the present invention, the discharge cylinder is provided with a fourth tilting material support layer, which has the same structure as the third tilting material support layer. The outer side of the discharge cylinder is also provided with a swing drive mechanism for each swing arm corresponding to the first supporting shaft of the fourth tilting material support layer. The swing drive mechanism includes a linkage rod that is hinged to the lower end of the corresponding swing arm. The linkage rod is horizontally arranged. A drive cylinder is hinged on the support frame, and the working end of the drive cylinder is hinged to the linkage rod. The outer side of the cooling shell is provided with a set of swing drive mechanisms corresponding to the first tilting material support layer, the second tilting material support layer, and the third tilting material support layer. The drive cylinders of the swing drive mechanisms of the first tilting material support layer, the second tilting material support layer, and the third tilting material support layer are located on the outer side of the cooling shell. During operation, the piston rod of the drive cylinder extends or retracts, pushing the linkage rod to move horizontally. The linkage rod drives each swing rod to swing around the axis of the support shaft, thereby driving each support shaft to rotate and causing the corresponding flipping material tray to flip around the support shaft, thus achieving unloading. The drive cylinders of each flipping material tray are independently controlled, which can realize layered unloading, ensuring sufficient material cooling time and smooth unloading.

Detailed Implementation

[0033] like Figure 1-14 The diagram shows a counter-current particle cooler with uniform material distribution, comprising a support frame 1, a discharge cylinder 2 mounted on the support frame 1, a vertical cooling shell 3 mounted on the upper side of the discharge cylinder 2, the cooling shell 3 being connected to the interior of the discharge cylinder 2, and fixed to the support frame 1. A feed inlet 4 is located on the upper side of the cooling shell 3, and an anti-stacking mechanism is provided on the cooling shell 3 corresponding to the feed inlet 4. A vertical central rotating shaft 5 is located inside the cooling shell 3, with its upper end connected to a rotating drive mechanism. A circumferential material distribution mechanism is located on the upper part of the central rotating shaft 5 corresponding to the feed inlet 4. The cooling shell 3 contains various material distribution mechanisms arranged sequentially from top to bottom. The cooling housing 3 has three horizontally rotating material support layers: a first rotating material support layer 6, a second rotating material support layer 7, and a third rotating material support layer 8. A uniform material distribution mechanism is located above the first rotating material support layer 6 and above the second rotating material support layer 7, respectively. A central rotating shaft 5 passes downwards through the first rotating material support layer 6 and the second rotating material support layer 7. A sweeping component is located at the lower end of the central rotating shaft 5, above the third rotating material support layer 8. The bottom of the discharge cylinder 2 has a discharge port 9, and the top of the cooling housing 3 has a suction cylinder 10. The suction cylinder 10 is connected to the interior of the cooling housing 3, and its upper end is connected to a blower.

[0034] The support frame 1 includes four horizontally arranged main side beams 1a. Each main side beam 1a has four columns 1b located at its respective corners on its lower side. A side reinforcing beam 1c is provided between any two adjacent columns 1b. The side reinforcing beams 1c enhance the overall rigidity and stability of the support frame 1. The discharge cylinder 2 has a rectangular cross-section in the horizontal direction. The flow area of ​​the discharge cylinder 2 decreases from top to bottom. The discharge cylinder 2 includes four cylindrical side plates 2a, which are inclined. The upper and lower ends of the four cylindrical side plates 2a form rectangles. The upper edges of the four cylindrical side plates 2a are fixed to the four main side beams 1a. The cooling shell 3 includes a main body section 3a, with a top shell section 3b on top of the main body section 3a. Both the main body section 3a and the top shell section 3b have rectangular cross-sections in the horizontal direction. The side walls of the main body section 3a of the cooling shell 3 are vertically arranged, and the side walls of the top shell section 3b of the cooling shell 3 are inclined. The flow area of ​​the top shell section 3b of the cooling shell 3 increases from top to bottom. Each side main beam 1a has a side base plate 11 on its upper side, and each side main beam 1a has a reinforcing support plate 12 fixed on its inner side. Each reinforcing support plate 12 supports the corresponding side base plate 11. The lower parts of the four side walls of the main body section 3a of the cooling shell 3 are fixed to the four side base plates 11 respectively. The flow area of ​​the discharge cylinder 2 decreases from top to bottom, forming an inverted truncated pyramid shape. The lower parts of the four side walls of the main body section 3a of the cooling shell 3 are respectively fixed to the four side base plates 11, thereby firmly installing the cooling shell 3 on the support frame 11. The lower opening of the cooling shell 3 is connected to the upper opening of the discharge cylinder 2. In order to increase the area of ​​the cooling shell 3, the reinforcing support plate 12 and the side base plates 11 can be omitted, so that the four side walls of the main body section 3a of the cooling shell 3 can be directly fixed on the four side main beams 1a.

[0035] The feed inlet 4 is located at the top of the top shell section 3b of the cooling shell 3. The anti-stacking mechanism includes a feed cylinder 13 located on the upper side of the top shell section 3b of the cooling shell 3. The feed cylinder 13 is positioned corresponding to the feed inlet 4. A transverse rotating shaft 14 is rotatably mounted inside the feed cylinder 13. One end of the transverse rotating shaft 14 extends out of the feed cylinder 13 and is connected to the dispersing motor 15. Multiple dispersing rods 14a are mounted on the outer periphery of the transverse rotating shaft 14. A guide cylinder 16 is located inside the cooling shell 3 corresponding to the feed inlet 4. When particulate material enters from above the feed cylinder 13, the dispersing motor 15 drives the transverse rotating shaft 14 and the dispersing rods 14a to rotate at high speed, breaking up any material that may clump or bridge. The guide cylinder 16 guides the material to fall accurately into the rotating drum 19.

[0036] The central rotating shaft 5 is located in the middle of the cooling housing 3. The rotating drive mechanism includes a drive motor 18 that is vertically mounted on the top of the cooling housing 3 via a bracket 17. The output end of the drive motor 18 faces downward. The upper end of the central rotating shaft 5 extends out of the cooling housing 3 and is connected to the drive motor 18 for transmission. The circumferential fabric distribution mechanism includes a vertical rotating cylinder 19 that is coaxial with the central rotating shaft 5. The upper end of the rotating cylinder 19 is open and is set corresponding to the guide cylinder 16. The central rotating shaft 5 passes through the bottom of the rotating cylinder 19 and is fixedly connected to it. The rotating cylinder 19 is provided with a number of radial connecting rods 20 that are circumferentially spaced around the central rotating shaft 5. The inner and outer ends of the connecting rods 20 are fixed to the central rotating shaft 5 and the inner wall of the rotating cylinder 19, respectively. The outer circumference of the rotating cylinder 19 is provided with a number of inclined discharge cylinders 21 that are evenly spaced circumferentially. The discharge cylinders 21 are connected to the interior of the rotating cylinder 19. The discharge direction of the discharge cylinder 21 is inclined outward and downward. When the drive motor 18 drives the central rotating shaft 5 and the rotating cylinder 19 to rotate at high speed, the material is evenly thrown from each discharge cylinder 21 to the surrounding area of ​​the cooling shell 3 under the action of centrifugal force, so as to achieve uniform circumferential material distribution.

[0037] The flip-up material support layer 6 includes several flip-up material support plates 22 arranged laterally. The flip-up material support plates 22 are arranged longitudinally. An inclined overlapping portion 22a is provided on the left side of each flip-up material support plate 22, and an inclined overlapping surface 22b is provided on the right side. The overlapping surface 22b of each flip-up material support plate 22 corresponds to the overlapping portion 22a of the adjacent flip-up material support plate 22.

Both the overlapping portion 22a and the overlapping surface 22b have the same inclination angle, and a labyrinth-like sealing fit is formed between two adjacent flipping material support plates 22, which effectively prevents fine powder materials from leaking from the gaps between the plates; the diameter of the ventilation micro-holes 26 is preferably 2-6mm, which can ensure that the cooling air passes through the material layer evenly, and prevent material particles from leaking out from the micro-holes. The clearance groove provides space for the passage of the central rotating shaft 5; the flipping directions of the flipping material support layer 1 6 and the flipping material support layer 2 7 are different, so as to realize layered unloading. The support shaft 24 of the flipping material support layer 1 6 is arranged longitudinally, the support shaft 28 of the flipping material support layer 2 7 is arranged transversely, and the support shaft of the flipping material support layer 3 8 is arranged longitudinally.

[0038] The uniform fabric distribution mechanism includes two sets of fabric cooling components symmetrically distributed on both sides of the central rotating shaft 5. The fabric cooling components are arranged longitudinally and include rectangular air boxes 29. A longitudinal lead screw 30 is provided on the upper side of each air box 29 inside the cooling housing 3. A longitudinal guide rod 31 is provided on both the left and right sides of each longitudinal lead screw 30. The front and rear ends of the guide rod 31 are fixed to the inner walls of the front and rear sides of the cooling housing 3, respectively. One end of the lead screw 30 is rotatably connected to the inner wall of the cooling housing 3, and the other end of the lead screw 30 passes through the corresponding inner wall of the cooling housing 3 and is connected to a moving motor 50. A transmission nut 32 is threadedly connected to the outer circumference of the lead screw 30. The transmission nut 32 is connected to the corresponding air box 29 via a transmission bracket 32a17. At least two guide seats 33 with front and rear spacing are provided on each guide rod 31 on the air box 29.

An adjustable rod 36 with an adjustable angle is installed on the mounting shaft 35. A brush head seat 37 is installed at the lower end of the adjusting rod 36. Several fabric rods 37a are arranged on the lower side of the brush head seat 37. The fabric rods 37a of the uniform fabric distribution mechanism are arranged corresponding to the flipping material support layer 6. The outer diameter of the fabric rods 37a is 2-4mm. Each air box 29 has an air inlet 3 on the rear side. 8. An air inlet duct 39 is provided on the rear side wall of the cooling housing 3 for each air inlet 38. The inlet of the air inlet duct 39 is connected to the blowing device. A retractable corrugated rubber tube 40 is provided between the outlet of the air inlet duct 39 and the corresponding air inlet 38. The uniform material distribution mechanism 2 includes two sets of material distribution and cooling components symmetrically distributed on both sides of the central rotating shaft 5. The material distribution and cooling components of the uniform material distribution mechanism 2 are arranged horizontally. The material distribution rod 37a of the uniform material distribution mechanism 2 is arranged corresponding to the flipping material support layer 2 7. When the moving motor 50 drives the lead screw 30 to rotate forward and backward, the transmission nut 32 moves back and forth along the lead screw 30, thereby driving the bellows 29 to move back and forth in the forward and backward direction. Each guide seat 33 ensures the guiding accuracy and stability of the bellows 29 during movement. The lower end of the material feeding rod 37a is about 5-15mm away from the upper surface of the flipping material support plate to move the material layer without damaging the material particles. The outer diameter of the material feeding rod 37a is preferably 3mm and is made of wear-resistant stainless steel. The inlet of the air inlet duct 39 is connected to the blowing device (such as a blower). The retractable corrugated rubber tube 40 between the outlet of the air inlet duct 39 and the corresponding air inlet 38 can adapt to the expansion and contraction requirements of the air supply pipeline when the bellows 29 moves back and forth. During operation, the bellows 29 moves back and forth along the guide rod 31 under the drive of the lead screw 30. The material feeding rod 37a continuously moves and flattens the material layer below. At the same time, the cooling air blown out from the air outlet duct 34 directly acts on the surface of the material layer, realizing the coordinated operation of material feeding and cooling.

[0039] Each of the left and right inner walls of the air outlet duct 34 is provided with a sub-seat 41. The mounting shaft 35 is positioned between the two symmetrical sub-seats 41. The upper end of the adjusting rod 36 is provided with a mounting ring 36a, which is rotatably fitted onto the mounting shaft 35. The mounting ring 36a has several circumferentially distributed connecting holes 42. The sub-seats 41 have several circumferentially distributed connecting holes 43 corresponding to each connecting hole 42. Several connecting bolts pass sequentially through the corresponding connecting holes 43 of the sub-seats 41, the connecting holes 42 of the mounting ring 36a, and the connecting holes 43 of the mounting ring 36a. The connecting hole 43 of the first sub-base body 41 is fitted with a locking nut for pressing the sub-base body 41 at the end of the connecting bolt. The lower end of the adjusting rod 36 is provided with a ball head 44. The upper side of the brush head seat 37 is provided with a ball cup 45 that matches the ball head 44. The ball head 44 of the adjusting rod 36 is fitted and installed in the ball cup 45 of the brush head seat 37. The sweeping assembly includes a mounting bracket 4617 set at the lower end of the central rotating shaft 5. The mounting bracket 4617 is provided with a number of sweeping rods 47 spaced apart along the length direction on the lower side. The sweeping rods 47 are set vertically, and each sweeping rod 47 is set corresponding to the flipping material support layer 8. By loosening the connecting bolts, the adjusting rod 36 can be rotated to the desired angle, and then the connecting bolts can be tightened again to change the tilt angle of the adjusting rod 36, thereby adjusting the position of the lower end of the fabric rod 37a and the feeding angle to adapt to materials with different particle sizes and flowability. The ball head 44-ball cup 45 connection structure allows the brush head seat 37 to adaptively adjust its angle, ensuring that the fabric rod 37a maintains good contact with the surface of the material layer. Even if the surface of the material layer is slightly uneven, the fabric rod 37a can still fit well.

[0040] The discharge cylinder 2 is provided with a tilting material support layer four inside, which has the same structure as the tilting material support layer three 8. The swing rods 25 of each supporting pivot 24 of the tilting material support layer four on the outside of the discharge cylinder 2 are also provided with a swing drive mechanism. The swing drive mechanism includes a linkage rod 48 that is hinged to the lower end of each corresponding swing rod 25. The linkage rod 48 is horizontally arranged. A drive cylinder 49 is hinged on the support frame 1. The working end of the drive cylinder 49 is hinged to the linkage rod 48. The outside of the cooling shell 3 is provided with a set of swing drive mechanisms corresponding to the tilting material support layer one 6, tilting material support layer two 7, and tilting material support layer three 8. The drive cylinders 49 of the swing drive mechanisms of the tilting material support layer one 6, tilting material support layer two 7, and tilting material support layer three 8 are located on the outside of the cooling shell 3. During operation, the piston rod of the drive cylinder 49 extends or retracts, pushing the linkage rod 48 to move horizontally. The linkage rod 48 drives each swing rod 25 to swing around the axis of the support shaft, thereby driving each support shaft to rotate and causing the corresponding flipping material tray to flip around the support shaft to achieve unloading. The drive cylinders 49 of each flipping material tray are independently controlled, which can realize layered unloading, ensuring sufficient material cooling time and smooth unloading.

[0041] The working process of this invention is as follows: (1) Feeding and preventing material accumulation: The material enters from the feed cylinder 13, and the dispersing motor 15 drives the dispersing rod 14a to rotate at high speed to disperse the material and prevent bridging; (2) Circumferential material distribution: The material falls into the rotating cylinder 19 through the guide cylinder 16. The drive motor 18 drives the central rotating shaft 5 and the rotating cylinder 19 to rotate simultaneously. Under the action of centrifugal force, the material is evenly distributed from each inclined discharge cylinder 21 to the periphery of the cooling shell 3. (3) Layer-by-layer spreading and cooling: The material falls onto the first flipping support layer 6 and the second flipping support layer 7 in sequence. The uniform material distribution mechanism above each layer moves back and forth, and the material is continuously spread by the material distribution rod 37a. At the same time, the air outlet 34 blows cooling air onto the material layer. The exhaust fan draws air from the top, and the bottom opening of the discharge cylinder 2 sends air into the cooler through the air supply and cooling device. The cold air passes through the ventilation micro-holes 26 on each flipping support layer from bottom to top and exchanges heat with the material in a countercurrent manner, taking away the heat and moisture of the material. The material on the first flipping support layer 6 and the second flipping support layer 7 simultaneously receives air blown from the top to the bottom by the air outlet 34 and cold air passing through the ventilation micro-holes 26 from bottom to top, which greatly improves the cooling effect. (4) Layered unloading: After the material is cooled by the first flipping support layer 6 and the second flipping support layer 7, the driving cylinders 49 of each flipping support layer are activated in sequence to drive each flipping support plate to flip, and the material falls layer by layer to the next layer until it falls on the third flipping support layer 8. (5) Sweeping and discharging: The sweeping component rotates with the central rotating shaft 5 to further sweep and level the material on the flipping material layer 3 8. Then, the flipping material plate of the flipping material layer 3 8 flips and sends the material to the flipping material layer 4. The flipping material layer 4 in the discharge cylinder 2 serves as a buffer unloading layer and receives cold air flowing from bottom to top for cooling. Finally, the cooled material is discharged from the discharge port 9 of the discharge cylinder 2.

[0042] The advantages of this invention are as follows: 1. By setting an anti-stacking mechanism (dispersing rod 14a), the particulate material that may bridging or arching is pre-dispersed at the feed inlet 4, effectively preventing material blockage at the feed inlet 4 and ensuring the continuity and stability of the feeding. 2. By setting a circumferential material distribution mechanism (rotating cylinder 19 and circumferentially distributed inclined discharge cylinder 21), centrifugal force is used to evenly distribute the material around the cooling shell 3, achieving preliminary uniform distribution of the material on the horizontal cross section, avoiding the problem of conical accumulation of material directly below the feed inlet 4 under traditional feeding methods. 3. By setting up two layers of uniform material distribution mechanisms (corresponding to the first flipping material support layer 6 and the second flipping material support layer 7 respectively), the reciprocating bellows 29 drives the material distribution rods 37a to move and flatten the material layer. At the same time, an air outlet duct 34 is set under the bellows 29 to blow cooling air into the material layer while distributing the material, realizing an integrated operation of "distributing material and cooling at the same time", which greatly improves the uniformity of material distribution and cooling efficiency. Combined with the cold air passing through the ventilation micro-holes 26 on each flipping material support layer from bottom to top, convection cooling is achieved. 4. The flipping material support plates adopt a "lap joint 22a + overlap surface 22b" mating structure, forming a labyrinth seal between adjacent flipping material support plates, effectively preventing fine powder materials from leaking from the gaps between the flipping material support plates. At the same time, each flipping material support plate is linked to the rotating shaft and the swing rod 25 for simultaneous and reliable unloading. 5. By setting three layers of rotating material support within the cooling shell 3 and a fourth rotating material support within the discharge cylinder 2, the material forms multiple layers within the cooler. Cooling air enters from the bottom and passes sequentially through the ventilation micro-holes 26 on each rotating material support plate, achieving thorough heat exchange with the material. This counter-current cooling effect is good, and energy consumption is low. 6. The sweeping assembly rotates with the central rotating shaft 5, sweeping the material on the third rotating material support 8 circumferentially. The first rotating material support 6 and the second rotating material support 7 sweep the material longitudinally and laterally, respectively, ensuring uniform material distribution and more thorough cooling. The overall structure of this invention is compact, the functional modules are rationally arranged, and the degree of automation is high, making it suitable for large-scale industrial production.
