Description

Technical Field

[0001] The utility model belongs to the field of filtering devices, and in particular relates to a conical filter cloth filtering structure. Background Art

[0002] The filter washing and drying machine is an integrated automated equipment with multiple functions of filtering, washing and drying, in which the filtering function is an indispensable part. According to the corrosion strength of different material media, the selection of appropriate metal filter layer materials (such as Hastelloy material) also greatly affects the equipment manufacturing cost; the conical filter cloth filtering structure can greatly reduce the production cost without affecting the operation of the equipment and convenient operation. However, most of the conical filter cloth structures on the market currently adopt the form of porous plate (medium side) + filter cloth + porous plate (fixed side). However, during use, filter cakes will form in the holes of the porous plate (medium side). The material blocking the porous plate will cause the filtration speed to slow down. At the same time, the high water content of the filter cake in the hole will also affect the drying rate. In addition, the filter cake in the hole is difficult to clean after drying, which increases the time cost of manual cleaning. Therefore, how to optimize the production cost of the filter washing and drying machine, so as to reduce manual intervention in the production process, reduce labor costs, and reduce production time costs, becomes particularly critical.
