Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a filter press and an auger connecting device. Background Art

[0002] The filter press is a commonly used solid-liquid separation device that uses a special filter medium to apply a certain amount of pressure to an object. The bottom of a traditional plate-and-frame filter press usually adopts a V-shaped hopper design, which is mostly made of cast iron or stainless steel. This hopper is usually connected to a conveyor belt below, and the part in contact with the conveyor belt is usually made of rubber material.

[0003] In the process of preparing silicon materials, the liquid silicon solution is dehydrated by a filter press to form silicon materials. However, during the filter press process, due to the source of the raw materials, the wear and tear inside the equipment, etc., a small amount of metal impurities may be mixed into the filter cake after the filter press, and the presence of these metal impurities has a serious impact on the purity of the silicon material. The presence of metal impurities will not only reduce the electrical properties of the silicon material, but may also affect its optical and mechanical properties. In particular, for high-purity silicon materials, such as electronic-grade silicon materials, the presence of metal impurities is even more unacceptable. Utility Model Content
