Technical Field
[0001] This utility model relates to the technical field of powder cooling processing equipment, specifically a low-temperature rapid curing powder cooling processing equipment. Background Technology
[0002] Low-temperature rapid curing powder is a powder material that can cure in a short time at a low temperature. The common type is low-temperature rapid curing powder coating, which is widely used in home appliances, automobiles and other fields. The production and processing of low-temperature rapid curing powder requires cooling processing. Powder cooling processing is a process that uses a cooling medium to cool powdered materials. It is widely used in materials preparation, metallurgy, chemical industry, 3D printing and other fields.
[0003] Traditional cooling methods typically employ natural static cooling, which relies on ambient temperature and takes several hours to cool down. This results in low cooling efficiency, uneven heat conduction due to powder accumulation, slow cooling in the central area, significant temperature differences between the upper and lower layers of powder during static cooling, and the need for numerous trays to hold the powder, leading to high costs. Utility Model Content
[0004] The purpose of this invention is to provide a low-temperature rapid curing powder cooling processing device to solve the problems mentioned in the background art. Traditional cooling methods usually adopt natural static cooling, which depends on the ambient temperature, takes several hours to cool down, has low cooling efficiency, uneven heat conduction due to powder accumulation, slow cooling in the central area, large temperature difference between the upper and lower layers of powder during static cooling, and requires a large number of trays to stack powder, resulting in high costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature rapid curing powder cooling processing device, comprising a bottom cooling water tank, a drain valve connected to one corner of the bottom cooling water tank, a mounting shell fixedly connected to the top of the bottom cooling water tank, two sets of positioning annular tracks symmetrically fixedly connected inside the mounting shell, a cooling cylinder rotatably connected to the middle of the two sets of positioning annular tracks, a drive assembly fixedly installed on one side of the mounting shell, a transmission assembly connected to the end of the drive assembly, a stirring component rotatably mounted inside the cooling cylinder, a feeding assembly fixedly connected to one end of the cooling cylinder, an air-cooling assembly symmetrically installed on one side of the mounting shell, a water-cooling assembly fixedly installed inside the bottom cooling water tank, and a discharge assembly movably connected to the other end of the cooling cylinder. This device uses a combination of air cooling and water cooling for cooling, resulting in faster cooling speed. It utilizes mechanical agitation of the powder to reduce temperature differences, ensuring uniform powder cooling and improving efficiency.
[0006] Preferably, the drive assembly includes a drive motor, which is fixedly installed in the middle of one side of the mounting housing. A drive gear is fixedly sleeved in the middle of the output shaft of the drive motor, and a drive pulley is fixedly connected to the end of the output shaft of the drive motor to provide power for the rotation of the stirring component and the cooling cylinder.
[0007] Preferably, the transmission assembly includes a driven pulley and meshing teeth. The driven pulley is fixedly connected to the end of the stirring component, and the meshing teeth are fixedly connected at equal angles to the outer side of one end of the cooling cylinder. The meshing teeth are connected to the driving gear, and a transmission belt is driven to the outer side of the driven pulley. The driven pulley is driven to the driving pulley through the transmission belt to form a transmission structure, which is driven by the same power.
[0008] Preferably, the feeding assembly includes a fixed door panel, which is rotatably connected to the middle of one end of the cooling cylinder. A feeding pipe is connected to the fixed door panel near the top edge. Two fixed connecting frames are symmetrically fixed to the fixed door panel near the bottom edge. The ends of the two fixed connecting frames away from the cooling cylinder are fixedly connected to the side of the bottom cooling water tank, so that the position of the feeding pipe remains unchanged when the agitator and the cooling cylinder rotate, which facilitates continuous feeding.
[0009] Preferably, the air-cooling assembly includes two exhaust fans, which are symmetrically and fixedly installed on one side of the mounting housing. A water-blocking arc plate is rotatably connected to the side of the mounting housing. A control switch is fixedly installed in the middle of the side of the mounting housing. A guide plate is obliquely and fixedly connected to the side of the cooling cylinder. Both the guide plate and the water-blocking arc plate have guide grooves on their inner walls to discharge heat from the inside of the cooling cylinder, forming forced convection and accelerating cooling.
[0010] Preferably, the water-cooling assembly includes a water supply pump, which is fixedly installed inside the bottom cooling water tank. The water supply pump is connected to a water supply pipe at its water delivery end, and a water collection plate is connected to the end of the water supply pipe. Multiple water injection nozzles are connected to the bottom end of the water collection plate. The water injection nozzles are fixedly embedded in the middle of the top of the mounting housing and penetrate the top wall of the mounting housing, cooling the cooling cylinder by water flow.
[0011] Preferably, the discharge assembly includes two connecting frames and a connecting block. The two connecting frames are symmetrically and fixedly connected to the outer side of the end of the cooling cylinder. The connecting blocks are rotatably connected inside the two connecting frames. A discharge gate is fixedly connected between the two connecting blocks. A locking bolt is threadedly connected to the outer side of the connecting frame at the bottom end, so that the powder in the device can be easily removed after cooling.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The design incorporates a water supply pump, water supply pipe, water collection plate, water injection nozzle, and exhaust fan to form a cooling structure that combines air cooling and water cooling. Air cooling removes heat from the cooling cylinder through airflow, while water cooling removes heat from the cooling cylinder through waterflow. At the same time, the exhaust fan creates forced convection to assist in heat dissipation in low-heat areas that are difficult to cover by water cooling, thus forming a comprehensive cooling network.
[0014] The design incorporates a drive motor, a drive gear, a drive pulley, a transmission belt, a driven pulley, a fixed connection frame, and a stirring component. The rotation of the stirring component agitates the powder in the cooling cylinder, while the rotation of the cooling cylinder changes the position of direct contact with the water jet from the water injection nozzle, reducing the temperature difference and ensuring uniform cooling.
[0015] The bottom cooling water tank, water baffle, and guide plate are designed to recycle the water used for cooling, reducing water waste and saving costs, while also reducing water spray and minimizing its impact on the processing environment. Attached Figure Description

[0021] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Please see Figure 1-4This utility model provides a low-temperature rapid curing powder cooling processing device, including a bottom cooling water tank 1. The bottom cooling water tank 1 can be supplied with water from an external water source during use. A drain valve 2 is connected to one corner of the bottom cooling water tank 1 to drain the used water. A mounting shell 3 is fixedly connected to the top of the bottom cooling water tank 1. Two sets of positioning annular tracks 4 are symmetrically fixedly connected inside the mounting shell 3. A cooling cylinder 27 is rotatably connected to the middle of the two sets of positioning annular tracks 4. A drive assembly is fixedly installed on one side of the mounting shell 3. The drive assembly is connected to a transmission assembly at the end. The cooling cylinder 27 is equipped with a rotating agitator 14, which mainly consists of an agitator shaft, agitator blades, and a fixed frame. The fixed frame is fixedly connected inside the cooling cylinder 27 to support the agitator shaft. The agitator shaft and the fixed frame are rotatably connected. The agitator shaft passes through the agitator frame and can rotate. One end of the cooling cylinder 27 is fixedly connected to a feeding assembly. Air-cooling assemblies are symmetrically installed on one side of the housing 3. A water-cooling assembly is fixedly installed inside the bottom cooling water tank 1. The other end of the cooling cylinder 27 is movably connected to a discharge assembly.
[0023] Furthermore, the drive assembly includes a drive motor 8, which is fixedly mounted on the middle of one side of the mounting housing 3. A drive gear 9 is fixedly sleeved on the middle of the output shaft of the drive motor 8, and a drive pulley 10 is fixedly connected to the end of the output shaft of the drive motor 8.
[0024] Furthermore, the transmission assembly includes a driven pulley 12 and meshing teeth 6. The driven pulley 12 is fixedly connected to the end of the stirring member 14, and the meshing teeth 6 are fixedly connected at equal angles to the outer side of one end of the cooling cylinder 27. The meshing teeth 6 are connected to the driving gear 9. A transmission belt 11 is driven to the outer side of the driven pulley 12. The driven pulley 12 is driven to the driving pulley 10 through the transmission belt 11. When the drive motor 8 rotates, it drives the driving gear 9 and the driving pulley 10 to rotate. The rotation of the driving gear 9 engages with the meshing teeth 6, causing the cooling cylinder 27 to rotate. At the same time, the rotation of the driving pulley 10 drives the driven pulley 12 to rotate through the transmission belt 11, causing the stirring member 14 to rotate. While stirring the powder inside the cooling cylinder 27, the cooling cylinder 27 rotates.
[0025] Furthermore, the feeding assembly includes a fixed door panel 5, which is rotatably connected to the middle of one end of the cooling cylinder 27. The fixed door panel 5 is connected to a feeding pipe 7 near the top edge. Two fixed connecting frames 13 are symmetrically fixed to the fixed door panel 5 near the bottom edge. The fixed connecting frames 13 fix the positions of the fixed door panel 5 and the feeding pipe 7, ensuring the stability of the feeding position of the feeding pipe 7 and facilitating the addition of powder. The ends of the two fixed connecting frames 13 away from the cooling cylinder 27 are fixedly connected to the side of the bottom cooling water tank 1. When cooling the powder, an appropriate amount of powder is first added to the inside of the cooling cylinder 27 through the feeding pipe 7, and then an appropriate amount of cooling water is added to the bottom cooling water tank 1.
[0026] Furthermore, the air-cooled assembly includes two exhaust fans 23, which are symmetrically fixedly installed on one side of the mounting housing 3. A water-blocking arc plate 24 is rotatably connected to the side of the mounting housing 3. A through hole is opened in the middle of the bottom end of the mounting housing 3, which, together with the positioning annular track 4, forms a relatively closed drainage space, allowing water to be discharged directly downwards. A control switch 15 is fixedly installed in the middle of the side of the mounting housing 3. The control switch 15 is used to control the start and stop of the drive motor 8, the water supply pump 16, and the exhaust fans 23, and simultaneously control the opening and closing of the air supply and closing mechanism. The switch 15 is connected to an external power source via a connecting wire to provide power. A guide plate 25 is fixedly connected to the side of the cooling cylinder 27 at an angle. Guide grooves are opened on the inner walls of both the guide plate 25 and the water baffle 24. The exhaust fan 23 is controlled by the control switch 15 to run, forming convection between the cooling cylinder 27 and the mounting shell 3 to exhaust the high-temperature air inside. At the same time, the air carries water mist and comes into contact with the water baffle 24. The water baffle 24 intercepts the water mist, and then it flows back to the bottom cooling water tank 1 through the guide plate 25.
[0027] Furthermore, the water cooling assembly includes a water supply pump 16, which is fixedly installed inside the bottom cooling water tank 1. The water supply pump 16 is connected to a water supply pipe 17 at its water delivery end, and a water collection plate 18 is connected to the end of the water supply pipe 17. Multiple water injection nozzles 19 are connected to the bottom end of the water collection plate 18. The water injection nozzles 19 are fixedly embedded in the middle of the top of the mounting housing 3 and penetrate the top wall of the mounting housing 3. While the cooling cylinder 27 rotates, the water supply pump 16 is controlled by the control switch 15 to transport the water inside the bottom cooling water tank 1 to the water collection plate 18 through the water supply pipe 17. Then, the water is sprayed onto the cooling cylinder 27 through the water injection nozzles 19 to cool the cooling cylinder 27. The water mist forms a water flow that flows downward along the cooling cylinder 27 and enters the bottom cooling water tank 1.
[0028] Furthermore, the discharge assembly includes two connecting frames 20 and a connecting block 21. The two connecting frames 20 are symmetrically fixedly connected to the outer side of the end of the cooling cylinder 27. The connecting block 21 is rotatably connected inside each of the two connecting frames 20. The upper connecting block 21 is rotatably connected inside the connecting frame 20 through a fixed horizontal shaft. A discharge gate 22 is fixedly connected between the two connecting blocks 21. A locking bolt 26 is threadedly connected to the outer side of the bottom connecting frame 20. After the powder cools down, the locking bolt 26 threadedly connected to the outer side of the bottom connecting frame 20 is unscrewed, and the discharge gate 22 is pulled upward to start collecting the cooled powder.
