Dual type filter

Dual type filter
A duplex filter (duplex switching filter) is a multi-purpose filtration equipment consisting of two stainless steel bag filters connected in parallel. It has many advantages such as a novel and reasonable structure, good sealing, strong flow capacity, continuous operation, and easy operation. It has a wide range of applications and strong adaptability. Especially the probability of side leakage of the filter bag is small, which can accurately ensure the filtration accuracy and quickly replace the filter bag. There is basically no material consumption in the filtration, which reduces the operating cost.
Structural principle
This equipment is entirely made of stainless steel SUS304/316L, with polished inner and outer surfaces. The filter cartridge is equipped with a stainless steel filter screen and a filter support basket; The top is equipped with a vent valve for discharging the air inside the filter during filtration. The connection between the upper cover and the filter cartridge adopts a quick opening structure, which is more convenient for cleaning (replacing) the filter screen. The three adjustable support feet can make the filter stand steadily on the ground. The connecting pipelines are connected by flexible joints or clamps, and the inlet and outlet valves are opened and closed by three-way ball valves, which are pressure and temperature resistant, flexible and convenient to operate, and have no material or liquid leakage, making them more hygienic. The pipeline joint adopts expansion connection, and the three-way external thread plug can be opened and closed flexibly. The device has a compact structure, easy operation, and simple maintenance.
