Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide powder production, in particular to a stirring device for production and processing of silicon carbide powder. Background Art

[0002] Emery, also known as silicon carbide, is made of quartz sand, petroleum coke (or coal coke), sawdust (salt is needed to produce green silicon carbide) and other raw materials through high-temperature smelting in a resistance furnace. Silicon carbide also exists in rare minerals in nature, moissanite.

[0003] When producing silicon carbide powder products, some auxiliary materials are added to the silicon carbide powder to improve the overall performance of the powder. The silicon carbide powder and auxiliary materials need to be stirred and mixed during production.

[0004] Chinese patent CN213913250U discloses a stirring device for production and processing of silicon carbide powder, including a stirring bin, a positioning seat is installed at the bottom of the stirring bin, the bottom surface of the positioning seat is inclined and a strip-shaped slide groove is opened on the bottom surface, a base is installed at one end of the bottom of the positioning seat, the positioning seat is hinged to the base, an angle adjustment mechanism is installed at the bottom of the base, the bottom of the base is fixedly connected to the angle adjustment mechanism, the angle adjustment mechanism includes an adjustment bin, and a screw is arranged inside the adjustment bin. The stirring bin of the stirring device for production and processing of silicon carbide powder can fully stir the material to ensure that the material is stirred evenly, and the inclination of the stirring bin can be adjusted through the angle adjustment mechanism, so that the material in the stirring bin can be fully discharged outward, and the inclination angle can be adjusted as needed. After the material in the stirring bin is discharged, the internal cleanliness is ensured to avoid the accumulation of materials inside and causing corrosion and deterioration.

[0005] The above patent only adjusts the mixing bin to an inclined state during material discharge so that the material slides down naturally. However, in the actual mixing process, some powder will adhere to the inner wall of the mixing bin and some powder will adhere to the mixing mechanism, which cannot fall off and be discharged by themselves, resulting in incomplete material discharge. Therefore, in view of the above situation, it is urgent to develop a mixing device for the production and processing of silicon carbide powder, which is convenient for cleaning the material attached to the inside of the mixing device and can discharge the material more thoroughly, so as to overcome the shortcomings in current practical applications and meet current needs.

A feeding port 101 is arranged on the top of the stirring box 1, and a top cover 102 is detachably mounted on the feeding port 101. A unloading port 103 is arranged on the bottom of the stirring box 1. A plug 5 for blocking the unloading port 103 is detachably mounted on the bottom of the stirring box 1. A stirring mechanism 2 extending to the inside of the stirring box 1 is installed on the top of the stirring box 1. A scraping mechanism 6 extending to the inside of the stirring box 1 is installed on the bottom of the stirring box 1. An auxiliary unloading mechanism 4 extending to the inside of the stirring box 1 for cleaning its inner wall and the stirring mechanism 2 is installed on the stirring box 1. The mixing box 1 is equipped with a lifting mechanism 3 for driving the auxiliary unloading mechanism 4 to move up and down. When in use, the material is first added into the mixing box 1, and the material is stirred by the stirring mechanism 2. After the stirring is completed, the plug 5 is removed to allow the material to be discharged from the unloading port 103. At the same time, the material is pushed by the scraping mechanism 6 to facilitate the discharge of the material. When most of the material in the mixing box 1 is discharged, the auxiliary unloading mechanism 4 is driven downward by the lifting mechanism 3, and the material attached to the mixing mechanism 2 is blown off by the auxiliary unloading mechanism 4. At the same time, the auxiliary unloading mechanism 4 scrapes off the auxiliary material attached to the inner wall of the mixing box 1. Finally, the material at the bottom of the mixing box 1 is pushed out by the scraping mechanism 6, so that the unloading is more sufficient.

[0025] The stirring mechanism 2 includes: a first motor 201, a transmission shaft 202 and stirring blades 203. The first motor 201 is fixed to the top of the stirring box 1. The output shaft of the first motor 201 is connected to the transmission shaft 202. A plurality of stirring blades 203 are arranged on the transmission shaft 202. When in use, the transmission shaft 202 and the stirring blades 203 are driven to rotate by the first motor 201, and the material is stirred by the stirring blades 203.

[0026] The auxiliary unloading mechanism 4 includes: an air pump 401, a hose 402, an annular tube 403, an air outlet nozzle 404 and a scraper ring 405. The air pump 401 is installed on the outside of the mixing box 1, and the annular tube 403 is installed inside the mixing box 1. The air pump 401 is connected to the annular tube 403 through the hose 402. A plurality of air outlet nozzles 404 pointing to the mixing mechanism 2 are installed in the annular tube 403. A scraper ring 405 is fixed on the outside of the annular tube 403, and the scraper ring 405 is in contact with the inner wall of the mixing box 1. When in use, air is blown into the annular tube 403 through the air pump 401, and the air flow is blown toward the transmission shaft 202 and the stirring blades 203 through the air outlet nozzle 404, thereby blowing off the material attached to the transmission shaft 202 and the stirring blades 203, and the material attached to the inner wall of the mixing box 1 is scraped off through the scraper ring 405.

[0027] The lifting mechanism 3 includes: an electric telescopic rod 301 and a transfer rod 302. There are two electric telescopic rods 301, which are installed on the outside of the mixing box 1. Each electric telescopic rod 301 is installed with a transfer rod 302 inserted into the mixing box 1 and fixed to the annular tube 403. The transfer rod 302 is slidably connected to the mixing box 1. When in use, the transfer rod 302 is driven to move up and down by the electric telescopic rod 301, and the annular tube 403 is driven to move up and down by the transfer rod 302.

The collar 602 is installed on the output shaft of the second motor 601. The scraper 603 is fixed to one side of the collar 602. The bottom of the scraper 603 fits with the inner bottom end of the mixing box 1. When in use, the collar 602 and the scraper 603 are driven to rotate by the second motor 601, and the material at the inner bottom end of the mixing box 1 is pushed to the discharge port 103 by the scraper 603 and falls.

[0029] Working principle: When using the stirring device for the production and processing of silicon carbide powder, first add the material into the stirring box 1, stir the material through the stirring mechanism 2, and after the stirring is completed, remove the plug 5 to allow the material to be discharged from the discharge port 103. At the same time, the material is pushed by the scraper mechanism 6 to facilitate the discharge of the material. When most of the material in the stirring box 1 is discharged, the electric telescopic rod 301 drives the transfer rod 302 to move downward, and the transfer rod 302 drives the annular tube 403 to move downward, and the annular tube 403 drives the transfer rod 302 to move downward. The scraper ring 405 moves, and the material attached to the inner wall of the mixing box 1 is scraped off by the scraper ring 405. At the same time, air is blown into the annular tube 403 through the air pump 401, and the air flow is blown to the transmission shaft 202 and the stirring blade 203 through the air outlet nozzle 404, thereby blowing off the material attached to the transmission shaft 202 and the stirring blade 203. The second motor 601 drives the sleeve ring 602 and the scraper 603 to rotate, and the scraper 603 pushes the material at the bottom end of the mixing box 1 to the discharge port 103 and drops it, thereby making the discharge more thorough.
