Sales of automatic mechanical plate and frame filter press

Sales of automatic mechanical plate and frame filter pressApplication field

Environmental protection industry: dewatering of residual sludge from municipal sewage treatment plants, treatment of industrial wastewater (such as chemical, electroplating, and papermaking wastewater), separation of river dredging sludge, achieving sludge reduction and resource utilization.

Chemical industry: pigment slurry separation in dye, pigment, and coating production, recovery of salt crystallization mother liquor, solid-liquid purification in pesticide and fertilizer production.

Mining and Metallurgy: Concentrate dewatering (such as copper, iron, and gold concentrates), tailings dry discharge, metallurgical sludge treatment (such as blast furnace sludge and electrolytic sludge), reducing tailings pond risks and recovering metals.

Food and Medicine: Starch processing, filtration of soy product residue, clarification of fruit juice, extraction of traditional Chinese medicine extract, meeting hygiene requirements, and the filtrate can be recycled.

New energy industry: filtration of lithium battery positive electrode material slurry to ensure material purity and recover solvents.

Sales of automatic mechanical plate and frame filter pressThe working principle of is mainly based on the physical filtering principle:

Building a filter chamber: Fix the filter cloth between the filter frame and the filter plate to form an independent filter chamber. The filter plates and filter frames are arranged alternately to ensure that each filter chamber can be effectively sealed.

Injecting material: Under the action of pressure (usually applied through mechanical devices), the material to be processed is injected into the filter chamber. Solid particles in the material are trapped on the filter cloth due to their size being larger than the filter cloth aperture, forming a filter cake; And the liquid part smoothly passes through the filter cloth and flows out of the filter chamber.

Solid liquid separation: As the material is continuously injected, the filter cake gradually thickens until it reaches the predetermined thickness or filtration effect. At this point, stop injecting the material and continue to maintain a certain pressure to further compact the filter cake and improve the solid-liquid separation effect.

Cleaning and unloading: After filtration, clean the filter cake to remove residual liquids and impurities. Then, open the filter plate and remove the filter cake from the filter chamber. At the same time, clean and replace the filter cloth to maintain its filtration efficiency and service life.
