Description

Technical Field

[0001] The utility model relates to the technical field of sand screening machines, in particular to a feeding device of a silicon carbide sand screening machine. Background Art

[0002] Silicon carbide is a synthetic substance. Due to its stable chemical properties, high thermal conductivity, small thermal expansion coefficient and good wear resistance, it can be used as an abrasive. After production, the raw materials need to be screened to remove impurities and retain silicon carbide particles. Before screening, the raw materials are fed by a feeding device and undergo a certain degree of primary processing.

[0003] The existing feeding device cannot control the feeding speed. When too much material is fed, the sand screening machine will be blocked. Secondly, agglomerated raw materials and raw materials with larger particle diameters will also affect the use of the sand screening machine and subsequent screening, reducing the utilization rate of the raw materials. Therefore, a feeding device for a silicon carbide sand screening machine is proposed to address the above problems. Utility Model Content

[0009] Preferably, the crushing chamber and the crushing chamber are connected via a connecting pipe at the top of the crushing chamber.

[0010] Preferably, the number of the spike teeth is several and they are evenly arranged on the outside of the crushing roller.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the partition, chute, fixing frame, nut, threaded rod and slide plate are arranged, so that the feeding speed can be controlled according to actual needs to prevent the sand screening machine from being blocked and affecting its use due to excessive feeding speed;

[0026] Working process: before using the device, first place the device in a suitable position, and then power the electrical equipment with an external power supply. When in use, feed the material into the crushing bin 1 through the feed port 2. The interior of the feed port 2 is fixedly connected with a partition 3. The slide plate 8 slides in the chute 4. The position of the threaded rod 7 is adjusted by the nut 6 in the fixing frame 5, and then the position of the slide plate 8 in the chute 4 is adjusted. The entry speed of the raw material is controlled by the size of the overlapping area of ​​the circular holes on the partition plate 3 and the slide plate 8. The material is adjusted in real time.
