Screening device for fused quartz material crushing

Abstract

The invention discloses a screening device for fused quartz material crushing. The screening device comprises an outer box body, wherein a feed hopper which penetrates through and extends into the outer box body is fixedly installed on the upper surface of the outer box body, a partition is fixedly installed on the inner top wall of the outer box body, a fixed base is fixedly installed at the bottom of the outer box body, and a motor box is fixedly installed on one side of the outer box body. According to the screening device, a buffer block and a connecting column are used cooperatively, so that the stability of a sieve plate is increased in a screening process, the condition that fused quartz materials are directly discharged due to excessive shaking is reduced, additionally, noise generated when equipment is used is reduced, and the service life of the equipment is prolonged; the screening device has the advantages of the simple structure and convenience in use, and screened fine powder can be collected by a protective shell and is discharged outside the equipment through the rotation of a conveying blade, so that the fine powder is prevented from being accumulated in the equipment, and the effect of discharging the screened fine powder in time is achieved.

Description

technical field [0001] The invention belongs to the technical field of mineral processing machinery and equipment, and in particular relates to a screening device for crushing fused quartz raw materials. Background technique [0002] Fused silica is the amorphous state of silicon oxide. The melting temperature of fused silica is about 1713°C. It has low thermal conductivity and almost the smallest thermal expansion coefficient among all refractory materials, so it has extremely high thermal shock stability. Therefore, during the firing and pouring process, the fused silica shell is rarely broken due to drastic temperature changes, and it is an ideal refractory material for investment casting. Screening process, during the use of existing screening devices, most of the raw materials are accumulated inside the equipment and cannot be discharged in a timely and effective manner. For example, the Chinese invention patent with the notification number CN107321600A discloses "a con...
