The duplex filter is composed of filter cylinder, barrel cover, valve, filter bag net, pressure gauge and other components, and the equipment is made of stainless steel material. The connection pipeline of the dual filter adopts a union or clamp connection method, and the inlet and outlet valves are opened and closed by two three-way ball valves. The two single cylinder filters are assembled on one machine base, and there is no need to stop when cleaning the filter to ensure its continuous operation. It is a non-stop production line filtration device. The filtering element of the dual filter, in addition to using stainless steel filter element, can also use honeycomb style degreased fiber cotton, which can filter out particle size 1 μ The above particles.

The working principle of the duplex filter: The suspension is pumped into each closed filter chamber of the filter, and under the action of working pressure, it is discharged through the filter outlet. The filter residue is left in the frame to form a filter cake, thereby achieving solid-liquid separation. The filtrate flows into the filter bag through the side inlet pipe of the filter casing. The filter bag itself is installed in a reinforced mesh basket, and the liquid penetrates through the required fineness level filter bag to obtain qualified filtrate. Impurity particles are intercepted by the filter bag.
