Description

Technical Field

[0001] The utility model relates to the technical field of batching systems, and more specifically to a device for batching silicon carbide. Background Art

[0002] Silicon carbide is an inorganic substance made from 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 nitride bonded silicon carbide is made by adding industrial silicon powder to silicon carbide aggregate. The silicon powder reacts with nitrogen at high temperature to generate Si3N4, which is tightly combined with silicon carbide particles to form Si3N4 bonded silicon carbide product materials.

[0003] The patent document with publication number CN219482323U in the prior art provides a device for silicon carbide batching, which adds silicon carbide raw materials into a batching box by pulling out a baffle plate on a feed hopper. After the feeding is completed, the baffle plate is plugged into the feed hopper, so that the batching process can be placed in a closed environment to prevent the dust generated during the batching process from splashing around, thereby facilitating the protection of the surrounding working environment. After the feeding, the stirring blades, spiral blades and scraper at one end of the fixed rod on the rotating rod are driven by a motor to rotate, so that the silicon carbide raw materials in the batching box can be batched.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, there are large particles of silicon carbide raw materials that are not crushed, affecting the product qualification rate; secondly, the use of the device requires manual allocation of the proportions of various raw materials, which is complicated and cumbersome and needs to be improved. In view of this, we propose a device for silicon carbide batching. Utility Model Content

[0028] A device for silicon carbide batching comprises a bottom plate 1, a mixing pool 2 is fixedly arranged on the top of the bottom plate 1, vertical plates 3 are fixedly arranged on both sides of the top of the bottom plate 1, a fixed frame 4 is fixedly arranged on the top of the inner wall of the vertical plate 3, a plurality of crushing components 5 are fixedly arranged in the fixed frame 4, the crushing component 5 comprises a rolling drum 501, a support frame 502 is fixedly arranged on the top of the rolling drum 501, a motor 503 is fixedly arranged inside the support frame 502, a rotating shaft 504 is fixedly arranged on the output end of the motor 503, a plurality of stirring rods 505 are fixedly arranged on the top of the circumferential outer wall of the rotating shaft 504, a rolling roller 506 is fixedly arranged in the middle of the circumferential outer wall of the rotating shaft 504, a feeding pipe 507 is fixedly arranged at the bottom of the mixing pool 2, a feeding port 508 is opened on one side of the top of the mixing pool 2, two fixed plates 6 are fixedly arranged in the middle of the inner wall of the vertical plate 3, a distribution component 7 is fixedly arranged on the top of the fixed plate 6, and the motor 503 is electrically connected to an external power supply. The utility model places the device for silicon carbide batching at the desired position through the bottom plate 1, fixes the grinding drum 501 through the fixing frame 4, puts the silicon carbide batching through the feeding port 508, drives the rotating shaft 504 to rotate by turning on the motor 503, breaks the large pieces of silicon carbide batching into small pieces through the stirring rod 505, and grinds the silicon carbide batching into the desired size through the grinding roller 506.

[0029] Specifically, the distribution assembly 7 includes a distribution barrel 701, a convex ring 702 is fixedly provided at the top of the circumferential outer wall of the distribution barrel 701, a weight sensor 703 arranged at the top of the fixed plate 6 is fixedly provided at the bottom of the convex ring 702, a discharge pipe 704 is fixedly provided at the bottom of the distribution barrel 701, a first discharge valve 705 is fixedly provided at the circumferential outer wall of the discharge pipe 704, and a second discharge valve 706 is fixedly provided at the circumferential outer wall of the discharge pipe 507. The second discharge valve 706 is controlled to be opened to allow the silicon carbide ingredients to fall into the distribution barrel 701, and the weight of the silicon carbide ingredients is sensed by the weight sensor 703. When the desired ratio is reached, the second discharge valve 706 is controlled to be closed, and the first discharge valve 705 is controlled to be opened, so that the silicon carbide ingredients enter the mixing tank 2 according to a certain ratio.
