Description

Technical Field

[0001] This application relates to the technical field of cooling devices, and in particular to a roller-type cooling device for peanut meal powder. Background Technology

[0002] The peanut meal powder drum cooling device is mainly used to uniformly cool peanut meal powder after high-temperature pressing or leaching by rotating the drum and allowing air convection, so as to quickly reduce its temperature and avoid residual heat causing oil oxidation, clumping or mold growth. At the same time, it maintains the looseness and nutritional components of the meal powder, which is convenient for subsequent storage, packaging or deep processing.

[0003] The existing peanut meal powder drum cooling device mainly consists of a drum body, a cooling system, and a stirring mechanism. The drum is horizontally positioned and features a design with one end closed and the other open. The closed end has a feeding port on its side wall, while the open end is equipped with a closable sealing door. The cooling system includes a cold air conveying device at the closed end and an air outlet at the top of the open end, forming a forced convection cooling channel. The stirring mechanism consists of internal flaps and an external drive assembly. During operation, the drive shaft drives the flaps to tumble the material. During cooling, peanut meal powder is loaded through the feeding port; the drive assembly is activated to rotate the flaps and stir the material, while the cooling device simultaneously delivers cold air; the heat-exchanged gas is discharged from the air outlet; after cooling is complete, the sealing door is opened to unload the material.

[0004] Regarding the aforementioned technologies, because the drum has a flap structure inside, when the sealed door is opened for discharge after cooling, the flap not only obstructs the smooth discharge of material but also leaves some peanut meal powder residue during rotation, resulting in incomplete cleaning. This not only increases the difficulty of manual cleaning but also reduces overall operational efficiency. Utility Model Content

[0005] To improve overall operational efficiency, this application provides a peanut meal powder drum cooling device.

[0006] The technical solution of the peanut meal powder drum cooling device provided in this application is as follows:

[0007] A peanut meal powder drum cooling device includes a drum body, one end of which is closed and the other end is open. A feeding port is provided through the side wall of the closed end of the drum body. A cooling device capable of supplying cold air into the drum body is provided at the closed end, and an air outlet is provided at the open end. A push plate is provided inside the drum body, with its side abutting against the inner wall of the drum body. A rotating shaft is rotatably connected to the end of the push plate facing the opening of the drum body. The length direction of the rotating shaft is parallel to the length direction of the drum body. Multiple flaps are provided around the circumference of the rotating shaft, evenly distributed along the circumferential side wall of the rotating shaft. One end of each flap... A sealing plate is rotatably connected to a rotating shaft at the end of the rotating shaft away from the push plate. The sealing plate is located outside the cylinder. A drive motor is fixedly installed on the side of the sealing plate away from the rotating shaft. The output shaft of the drive motor passes through the sealing plate and is fixedly connected to the rotating shaft. A drive assembly capable of driving the sealing plate to move along the length of the cylinder is provided on the outer wall of the cylinder. An annular plate is provided at the open end of the cylinder. The annular plate is connected to the cylinder. Multiple scrapers are connected to the annular plate. The multiple scrapers are located between adjacent flaps. The two sides of the scrapers abut against the two flaps on both sides. A first moving assembly for driving the annular plate to move along the length of the cylinder is provided on the cylinder.

[0008] By adopting the above technical solution, during the cooling operation, the sealing plate and the annular plate abut against each other, sealing the opening end of the cylinder. Peanut meal powder is fed into the cylinder through the feeding port. The drive motor is started to drive the rotating shaft and the tipping plate to rotate and stir the material. At the same time, the cooling device delivers cold air into the cylinder, and the gas after heat exchange is discharged from the air outlet. After cooling is completed, the drive assembly drives the sealing plate, rotating shaft, tipping plate, and the push plate connected to them to move towards the opening end of the cylinder. The push plate pushes the peanut meal powder in the cylinder towards the opening end for unloading. Simultaneously, the first moving assembly drives the annular plate and its scraper to move out of the cylinder to a set position. Then, during the movement of the tipping plate out of the cylinder, the scraper is fixed relative to the cylinder. The scraper can effectively scrape off the residual meal powder adhering to the surface of the tipping plate. When the push plate moves to the opening end of the cylinder, the unloading of the cylinder is completed. There is no need for manual unloading by the staff, saving time and improving the overall operation efficiency.

[0009] Optionally, a support leg is fixed to the bottom side of the cylinder.

[0010] By adopting the above technical solution, the outriggers are used to support the entire cylinder, allowing it to be placed stably on the ground.

[0011] Optionally, support plates are fixed on both opposite sides of the cylinder, the support plates are horizontally arranged, and auxiliary plates are fixed on the support plates. The driving assembly includes a threaded sleeve and a screw. The length direction of the threaded sleeve is parallel to the length direction of the cylinder.

Connecting plates are fixed on both opposite sides of the sealing plate. One end of the screw is fixedly connected to the connecting plate. A rotating assembly capable of driving the threaded sleeve to rotate is provided on the support plate.

[0012] By adopting the above technical solution, the rotating component drives the threaded sleeve to rotate. Since the threaded sleeve is threadedly connected to the screw, and the screw is fixed to the sealing plate through the connecting plate, the sealing plate restricts the rotational freedom of the screw. The rotation of the threaded sleeve is converted into linear movement of the screw along the length of the cylinder. Thus, the first moving component achieves the working efficiency of driving the sealing plate to move.

[0013] Optionally, a synchronous motor is fixedly mounted on the support plate, and the rotating assembly includes a first gear and a second gear. The first gear is fixedly connected to the output shaft of the synchronous motor, and a threaded sleeve passes through the second gear. The threaded sleeve and the second gear are fixedly connected, and the first gear and the second gear mesh.

[0014] By adopting the above technical solution, the synchronous motor starts, and the output shaft of the synchronous motor drives the first gear to rotate. The first gear drives the second gear meshing with it to rotate, and the second gear drives the threaded sleeve to rotate, thereby driving the screw and the sealing plate to move. Thus, the rotating assembly realizes the function of driving the threaded sleeve to rotate.

[0015] Optionally, the annular plate has an annular groove on the side facing the sealing plate, the annular groove is connected end to end, and multiple sliders are slidably connected to the annular plate in the annular groove. The side of the slider facing out of the annular groove is fixedly connected to the scraper and corresponds one-to-one.

[0016] By adopting the above technical solution, during the flipping process, the flipping plate pushes the scraper to move, and the scraper drives the slider to move in the annular groove. The setting of the annular groove and the slider realizes the sliding connection between the scraper and the annular plate.

[0017] Optionally, fixed plates are fixed on both sides of the annular plate, and the fixed plates and connecting plates are parallel. Guide rods are fixed on both sides of the outer wall of the cylinder, and the length direction of the guide rods is parallel to the length direction of the cylinder. A moving groove is opened on the side of the guide rod away from the cylinder along its own length direction. The first moving component includes a moving block and a first rack. Two moving blocks and a first rack are provided. The moving blocks are respectively located in two moving grooves. The moving blocks and guide rods are slidably connected. The first rack is fixedly connected to the side of the moving blocks facing the moving groove. The length direction of the first rack is parallel to the length direction of the cylinder. The end of the first rack near the fixed plate is fixedly connected to the fixed plate. A second moving component capable of driving the first rack to move is provided at the guide rod.

[0018] By adopting the above technical solution, the second moving component drives the first rack to move, and the first rack drives the moving block fixed to it to slide within the moving groove of the guide rod. At the same time, the first rack drives the fixed plate and the annular plate to move along the length of the cylinder. The guide rod and the moving groove provide guidance and support for the movement of the annular plate.

[0019] Optionally, a fixed rod is provided on one side of the movable plate, and one end of the fixed rod is rotatably connected to the cylinder. The second movable component includes a third gear and a fourth gear, both of which are fixed on the fixed rod. A second rack is fixed on the side of the connecting plate facing the cylinder. The length direction of the second rack is parallel to the length direction of the first rack. The second rack and the third gear mesh and are engaged, and the fourth gear and the first rack mesh.

After the annular plate moves to the set position, the second rack and the third gear disengage, so that the second moving component realizes the function of driving the first rack to move.

[0021] Optionally, a support rod is fixed to the side of the sealing plate facing the drive motor. The support rod is vertically arranged, and a roller is connected to the bottom end of the support rod. The roller is in contact with the ground.

[0022] By adopting the above technical solution, during the movement of the sealing plate, the sealing plate drives the support rod to move, and the support rod drives the roller to roll on the ground. The support rod and roller provide additional support for the moving sealing plate and drive motor, thereby improving the stability of the sealing plate movement.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The sealing plate is driven to move away from the cylinder by the first moving component. The sealing plate drives the rotating shaft to move, and the rotating shaft drives the flap and push plate to move. During the movement of the push plate, the push plate pushes the material in the cylinder towards the opening end of the cylinder. The material is removed from the cylinder from the opening end of the cylinder. At the same time, the scraper scrapes the material attached to the flap, so that the material is separated from the flap and falls out of the cylinder. There is no need for the staff to manually remove the material from the cylinder, which avoids the impact of the flap on the cleaning of the material, thereby improving the overall work efficiency.

[0025] 2. The second rack can drive the third gear to rotate, the third gear drives the fourth gear to rotate through the fixed rod, and the fourth gear drives the first rack to move. There is no need to provide separate power for the movement of the first rack, which saves resources.

[0036] First, open the cover plate 9 and feed the material into the cylinder 1 through the feeding port 11. After feeding, close the cover plate 9. Then, start the drive motor 24 and the cooling component 12. The cooling component 12 delivers cold air into the cylinder 1. The drive motor 24 drives the rotating shaft 21 to rotate. The rotating shaft 21 drives the flip plate 22 to flip. The flip plate 22 drives the material to tumble. After the cold air heat exchange is completed, the gas is removed from the cylinder 1 through the air outlet 13.

[0037] refer to Figure 1 , Figure 2 and Figure 3 Support plates 17 are fixed on both opposite outer walls of the cylinder 1. The support plates 17 are horizontally arranged. Auxiliary plates 18 are fixed on the support plates 17. The auxiliary plates 18 are perpendicular to the support plates 17. A drive assembly 3 that can drive the sealing plate 23 to move along the length of the cylinder 1 is provided at the auxiliary plate 18.

[0038] The drive assembly 3 includes a threaded sleeve 31 and a screw 32. The length direction of the threaded sleeve 31 is parallel to the length direction of the cylinder 1.

The second gear 52 drives the threaded sleeve 31 to rotate. Guided by the connecting plate 25, the threaded sleeve 31 drives the screw 32 to move. Under the coordinated action of the two screws 32, the screw 32 drives the connecting plate 25 to move, which in turn drives the sealing plate 23 to move. The sealing plate 23 then drives the rotating shaft 21 to move outward from the cylinder 1. The rotating shaft 21 drives the flap 22 to move. During the outward movement of the flap 22, the flap 22 is always rotating. At the same time, the rotating shaft 21 drives the push plate 2 to move. During the outward movement of the push plate 2, the material inside the cylinder 1 is pushed to move out of the cylinder 1. When the push plate 2 moves to the opening end of the cylinder 1, the sealing plate 23 stops moving, completing the cleaning of the material inside the cylinder 1. Then, the synchronous motor 171 drives the first gear 51 to reverse, and the sealing plate 23 moves towards the cylinder 1 to seal the opening end of the cylinder 1 again.

[0041] refer to Figure 1 , Figure 2 and Figure 3 Support rods 8 are fixed on both sides of the sealing plate 23.

After moving block 41 and moving groove 61 abut against the side wall of fixed plate 143, second rack 26 and third gear 71 disengage. As flip plate 22 continues to move away from cylinder 1, scraper 15 scrapes off the material attached to flip plate 22. The material falls downwards due to gravity. As sealing plate 23 moves towards cylinder 1, sealing plate 23 drives connecting plate 25 to move. Connecting plate 25 drives second rack 26 to move. During the movement of second rack 26, second rack 26 meshes with third gear 71 again and drives third gear 71 to reverse. Through the transmission of fixed rod 19 and fourth gear 72, first rack 42 drives fixed plate 143 to move towards cylinder 1.

The sealing plate 23 drives the rotating shaft 21 and the flip plate 22 to move. The rotating shaft 21 drives the push plate 2 to move. The push plate 2 pushes the material in the cylinder 1 towards the opening end of the cylinder 1. When the material reaches the opening end of the cylinder 1, it is removed from the cylinder 1. At the same time, as the flip plate 22 moves out of the cylinder 1, the scraper 15 scrapes off the material attached to the flip plate 22. After the material in the cylinder 1 is cleaned, the drive assembly 3 drives the sealing plate 23 to move towards the cylinder 1.
