Description

Technical Field

[0001] The utility model belongs to the technical field of batching devices, and in particular relates to a corrosion-resistant silicon carbide raw material batching device. Background Art

[0002] When producing corrosion-resistant silicon carbide, it is necessary to first weigh and batch the corrosion-resistant silicon carbide raw materials, confirm the ratio, then stir the weighed and batched raw materials, and finally bag them for subsequent operations. In the prior art, an electronic scale is generally used to weigh each raw material one by one, and then the weighed raw materials are transferred to a batching tank. However, in the process of transferring the raw materials from the electronic scale to the batching tank, a large amount of dust will be generated, and the workers will inhale a large amount of dust, which will damage their health. In addition, the operation and transfer process is cumbersome and the work efficiency is low.

[0003] For example, the Chinese utility model patent with application number 202221171883.9 discloses a raw material batching machine for preparing silicon carbide, in which a weighing box can automatically weigh the material, and a flip motor can automatically flip the material, eliminating the need for manual calculation and loading, greatly improving production efficiency. However, since there is no sealing structure at the weighing point, a large amount of dust is easily generated during loading and transportation from the weighing box to the feed barrel, which can harm the health of the workers.

[0013] 1. The circular air door is closed when not in use. When in use, by opening the circular air door, the raw materials in the batching box can be dropped into the mixing device of the next step through the discharge pipe at one time, avoiding the problem of uneven proportion due to the addition of new raw materials when the mixing device of the next step is still working;
