The customer runs a big company of walnut, mainly engaged in the sale of walnut oil. The walnut oil from the oil press and has many impurities. In order to reach get clear and bright oil and sell, the oil must be filtered, because in the oil has too much impurities, looks muddy. So it is necessary to need filter oil.
This project include automatic candle filter housing+ mixing tank and platform
First, it need to add diatomite to the mixing tank and fully mix with oil.
While filtering, the oil will be sent into the filter housing by feed pump, when it passes through filter cloth, solid particles will be stopped on the filter cloth. And as the solid particles growing, they will become filter cakes. The holes between solid particles are very small, so they keep more solid particles, thus get clear liquid. Before solid particles becoming cakes, the filtration will be sent back to filter material tank and resend to vessel again.
When filter cakes formed (and reaches required requirement), PLC will send a signal to stop the circulation, and the clear liquid will pass the filter valve and go to next process to start the normal filtering process.
Add the diatomite
Mixing of oil and diatomite
After filtration oil
When it use automatic candle filter housing to filter oil, must add diatomite to do precoating, otherwise the cartridge will be blocked.
