Product Description
Introduction & Application:
Filter press is a common used filtration and separation equipment,It has been widely used in the chemical production in the early 18th century and now is widely used in chemical industry, pharmaceutical industry, metallurgy industry, dyes industry, food factories, brewing, ceramics, and environmental protection industries.
Its main structure is :frame,filter plates,filter cloth,hydraulic station,PLC electric control system.The filter plates and filter plates frame forms the chamber ,the sludge (slurry)is pumped into the chamber and with the pressure ,filter cake will be formed in the chamber and filtrate will flow out through the outlet of the filter plates.
The automatic filter press is batch operation,which means that the operation must be stopped to discharge the filter cake before the next batch can be startedone filtering cycle usually takes from 20 minutes to 3 hours ,depending on the different characteristics of filtering material.There are 3 types filter press,ie recessed filter press,plate and frame filter press and vertical filter press.our filter plates have the advantages of stable permance,easy operation,accurate size,can endure high pressure and high temperature.
The size of our filter plates size are: 320 ,450,630,800,1000,1250,1500 and 2000 mm. we can also custmize the size of the plates depending on clients requirements.
Working Principle
The process of one batch filtration is:
(pressing---feeding material---filtering---discharging cake)
1- Closing of the filter plates: when start the press button on the PLC control cabinet, the moving head plates will be activated by the hydraulic calmps the plates.
2- Filling:The sludge (or slurry) will be pumped into the chamber one by one.when all chamber is full of filter cake,the filtration is finished.
3- Filter opening: The moving head is drawn back to disengage the first filtration chamber. The cake falls will drop from the plates because of gravity. The auto pulling system pulls out the plates one by one.
4- Washing: Usually for washing of clothes should be carried out every 15-100 batches.
