Description

Technical Field

[0001] The utility model relates to the field of filter devices, in particular to a novel belt-type vacuum filter. Background Art

[0002] Vacuum belt filters are widely used in industries such as metallurgy, mining, chemicals, papermaking, food, and pharmaceuticals. With the continuous development of various industries, the requirements for the treatment effect of vacuum belt filters are constantly increasing. Traditional vacuum belt filters use a vacuum pump to draw suction from a vacuum box to create negative pressure to process the material on the surface of the mesh belt above the vacuum box. The mesh belt intercepts the granular material, and the moisture in the material enters the vacuum box due to the negative pressure, flows into the vacuum drain tank, and is finally discharged into the sewage treatment system. The material is then transported to the temporary storage area via the mesh belt.

[0003] The traditional vacuum filter also has a mobile disc filter. Its basic principle is the same as that of the vacuum belt filter. Its vacuum box is driven by a cylinder to perform reciprocating motion to achieve material transportation. The negative pressure area of ​​this structure intermittently sucks the material.

[0004] The disadvantage of traditional vacuum belt filters is that when processing certain materials, the materials crack and leak on the surface, which reduces the vacuum negative pressure and affects the discharge effect. The mobile disc filter needs to remove the vacuum every time it works, and cannot operate continuously. It has high energy consumption, low output and high failure rate. Utility Model Content
