Description

Technical Field

[0001] This utility model relates to the field of silicon carbide technology, specifically to a silicon carbide particle airflow pulverizing and shaping device. Background Technology

[0002] A silicon carbide particle airflow pulverizing and shaping device is used to pulverize and shape silicon carbide particles. It is widely used in the production and processing of silicon carbide particles, improving production efficiency, reducing production costs, and improving product quality. Patent CN118268105A discloses a silicon carbide particle airflow pulverizing and shaping device, including a pulverizing chamber. From top to bottom, the pulverizing chamber is arranged a distributor, a first chamber, a second chamber, and a third chamber. The inner diameters of the first and third chambers are both larger than the inner diameter of the second chamber. A ring-shaped air pipe is installed circumferentially on the third chamber, and several high-pressure air ports are installed on the inner wall of the third chamber. A receiving chamber is installed at the end of the first chamber away from the second chamber, and a discharge channel is installed on the side wall of the receiving chamber. A feeding channel is installed on the top of the distributor. Because the inner diameters of the first, second, and third chambers are different, the internal structure of the pulverizing chamber resembles a Laval nozzle, which further accelerates the high-speed airflow, allowing for more intense collisions between silicon carbide particles, resulting in smaller silicon carbide particles. However, the aforementioned patent has the following shortcomings: when the device is in use, silicon carbide particles can easily clog the inside of the feed hopper, reducing the device's efficiency. Furthermore, when the device is not in use, it lacks a dustproof mechanism, allowing dust to easily enter the device from the discharge channel, making it inconvenient to use. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a silicon carbide particle airflow pulverizing and shaping device, which solves the problems that when the device is in use, silicon carbide particles are easy to clog the inside of the feed hopper, which reduces the working efficiency of the device. Moreover, when the device is not in use, the device lacks a dustproof mechanism, and dust can easily enter the device from the discharge channel, making the device inconvenient to use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 A silicon carbide particle airflow pulverization and shaping device includes a pulverization and shaping device body 1, a discharge channel 2 on the pulverization and shaping device body 1, a dustproof mechanism 3 inside the discharge channel 2, a feed hopper 4 on the pulverization and shaping device body 1, a first mounting strip 5 fixedly connected inside the feed hopper 4, a push rod 6 in contact inside the first mounting strip 5, a fixing plate 7 fixedly connected to the upper end of the push rod 6, and a pull ring 8 fixedly connected to the upper end of the fixing plate 7. By designing the pull ring 8, the fixing plate 7 can be moved. An elastic locking block 9 is internally engaged and fixedly connected to the push rod 6. The elastic locking block 9 can limit the push rod 6. A connecting plate 10 is fixedly connected to the lower end of the push rod 6. The connecting plate 10 contacts the first mounting strip 5. A connecting block 11 is fixedly connected to the lower end of the connecting plate 10. A push block 12 is fixedly connected to the lower end of the connecting block 11. By pushing the push rod 6 downward, the push rod 6 moves downward to push the silicon carbide particles, thereby preventing the silicon carbide particles from clogging the inside of the feed hopper 4 and preventing the working efficiency of the device from decreasing.

[0022] Please see Figure 4 , Figure 5 The dustproof mechanism 3 includes a filter screen 31. The filter screen 31 is fixedly connected inside the discharge channel 2. A motor 32 is fixedly installed on the outside of the discharge channel 2. The rotating shaft of the motor 32 is rotatably connected to the discharge channel 2. A rotating rod 33 is fixedly connected to the lower end of the rotating shaft of the motor 32. The discharge channel 2 is rotatably connected to the rotating rod 33. The rotating rod 33 is made of iron. By designing the rotating rod 33 to be made of iron, the rotating rod 33 becomes more durable.

[0023] Please see Figure 4 , Figure 5A first bevel gear 34 is fixedly connected to the lower end of the rotating rod 33. A second bevel gear 35 meshes with the outer side of the first bevel gear 34. A second mounting strip 37 is fixedly connected inside the discharge channel 2. A rotating column 36 is rotatably connected inside the second mounting strip 37. The rotating column 36 is fixedly connected to the second bevel gear 35. An annular sleeve 38 is fixedly connected to the outer side of the rotating column 36. The annular sleeve 38 contacts the second mounting strip 37. An annular groove 39 is formed inside the annular sleeve 38. A fixing block 310 is slidably connected inside the annular groove 39. 310 is fixedly connected to the second mounting strip 37. By designing an annular groove 39, the fixed block 310 can slide in the annular groove 39. An impact rod 311 is fixedly connected to the rotating column 36, and an elastic block 312 is fixedly connected to the filter screen 31. External dust is filtered through the filter screen 31, thereby preventing dust from entering the device from the discharge channel 2, making the device easy to use. Rotating the impact rod 311 impacts the elastic block 312 and the filter screen 31 to vibrate, thereby preventing the filter screen 31 from clogging and preventing the working efficiency of the filter screen 31 from decreasing.

[0024] The specific implementation process of this utility model is as follows: When the feed hopper 4 on the device is blocked, the pull ring 8 moves downward. The pull ring 8 moves downward, which drives the fixing plate 7 to move downward. The fixing plate 7 moves downward, which drives the push rod 6 to move downward. The push rod 6 moves downward, which drives the elastic block 9 and the connecting plate 10 to move downward. The elastic block 9 moves downward and separates from the first mounting strip 5. The push rod 6 moves downward, which drives the connecting plate 10 to move downward. The connecting plate 10 moves downward, which drives the connecting block 11 to move. The connecting block 11 moves downward, which drives the push block 12 to move downward. The push block 12 moves downward and pushes the silicon carbide particles, thereby preventing the silicon carbide particles from blocking the inside of the feed hopper 4 and preventing the working efficiency of the device from decreasing.

[0025] When the device is not in use, the filter screen 31 filters external dust, thereby preventing dust from entering the device from the discharge channel 2, making the device easy to use. When the device is used for a long time, the motor 32 is started, and the motor 32 drives the rotating rod 33 to rotate. The rotation of the rotating rod 33 drives the first bevel gear 34 to rotate, the first bevel gear 34 drives the second bevel gear 35 to rotate, the second bevel gear 35 drives the rotating column 36 to rotate, the rotating column 36 drives the impact rod 311 to rotate, the impact rod 311 drives the annular sleeve 38 and the impact rod 311 to rotate, the annular sleeve 38 drives the annular groove 39 to rotate, and the impact rod 311 vibrates when it impacts the elastic block 312. The vibration of the elastic block 312 causes the filter screen 31 to vibrate, thereby preventing the filter screen 31 from clogging and preventing the working efficiency of the filter screen 31 from decreasing.
