Operating characteristics of the filter press feed pump

Author: Fu-pump Time: 2017-01-06 Hits:


Filter press feed pump is currently the most commonly used filtering equipment, mostly used in coal washing, beneficiation and sewage treatment industries. The filtration process of the filter pump feed pump is divided into four stages.

(1) In the first stage (feeding period), as the feed pump is turned on and running, the material in the working space of the filter press increases from scratch, and the pressure gradually increases from zero until the material fills the working space.

(2) The second stage (filter press period) At this stage, the working space of the filter press is already full of slurry. Under the pressure of the pump, the water in the material medium is squeezed out through the filter cloth, and the pressure rise is relatively gentle.

(3) The third stage (holding period) In this stage, the working space of the filter press is full of materials, and there is no longer a large amount of water filtering out. Meet the moisture content requirements of the material.

(4) Fourth stage (discharging period) In this stage, the plate frame is successively opened to make the cake fall to the scraper conveyor until the discharging is completed.

The above four stages are a cycle and run repeatedly, that is, the working process of the filter pump feed pump.
