Product Structure

The cylinder is the main part of the filter. The large size cylinder is made of welded steel plate, the small size made of cast cylinder, and some old-fashioned filter cylinder made of thick wood. The filter cylinder is divided into some filtering chambers by strip along the circumferential direction. These chambers are strictly sealed without ventilation between each other. The filter plate is laid on the filter chamber forming a channel for filtrate and supporting filter cloth.

The cylinder is wrapped in filter cloth to ensure the sealing between each chamber.

There is a pipe at one end of the cylinder body which has the same number of channels as chambers. Each channel connects with the corresponding filter chamber. The transmission mechanism drives the cylinder and could transform several speeds.
