Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of silicon carbide sand screening machines, and in particular to a feeding device for a silicon carbide sand screening machine. Background Technology
[0002] Silicon carbide is a synthetic material. Due to its stable chemical properties, high thermal conductivity, low coefficient of thermal expansion, and good wear resistance, it can be used as an abrasive. After production, the raw material needs to be screened to remove impurities and retain silicon carbide particles. Before screening, it is fed by a feeding device, which also performs a certain degree of primary treatment on the raw material. Existing feeding devices cannot control the feeding speed. When too much material is fed, the sand screening machine will become clogged. Furthermore, agglomerated raw materials and raw materials with large particle diameters will also affect the use of the sand screening machine and subsequent screening, reducing the utilization rate of raw materials.
[0003] Currently, existing technology (CN 222446645 U) discloses a feeding device for a silicon carbide sand screening machine, including a crushing chamber, a feed inlet, and a discharge pipe. A drive motor is fixedly connected to the outside of the crushing chamber, and a transmission belt is provided on the outside of the drive motor's power shaft. A drive shaft and a secondary shaft are rotatably connected inside the crushing chamber. A main gear is fixedly connected to the outside of one end of the drive shaft, and a main crushing roller is fixedly connected to the outside of the drive shaft. A secondary gear is fixedly connected to the outside of one end of the secondary shaft, and a secondary crushing roller is fixedly connected to the outside of the secondary shaft. A support column is fixedly connected to the bottom of the crushing chamber. Through the setting of partitions, chutes, fixing frames, nuts, threaded rods, and sliding plates, the feeding speed can be controlled according to actual needs to prevent the sand screening machine from being blocked due to excessive feeding speed, thus affecting its use.
[0004] Using the above method, silicon carbide will generate a large amount of dust during the feeding process. The dust overflows and pollutes the working environment, posing a health hazard to the operators. Utility Model Content
