Filter Press Produced by the Filter Press Manufacturer

The filter press produced by the filter press manufacturer is a kind of mechanical equipment that uses special filter media to exert a certain pressure on objects to make liquids penetrate. It is a commonly used solid separation equipment. It has been used in chemical production since the beginning of the 18th century and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, environmental protection, and other industries.

The filter plates of the filter press produced by the filter press manufacturer have stable performance, easy, safe, and convenient operation. The metal extrusion cylinder is made of smooth steel pipe processing and plastic steel filter plates, which can withstand high temperature and high pressure.

What is the Filter Mechanism of the Filter Press Produced by the Filter Press Manufacturer?

The filter press produced by the filter press manufacturer consists of a filter plate, a filter frame, a filter cloth, and an extruded diaphragm. The two sides of the filter plate are covered with filter cloth. When the extruded diaphragm needs to be formed, the filter plate set consists of a diaphragm and a side plate. The base plate of the plate is covered with a rubber diaphragm on both sides, the outside of the diaphragm is covered with filter cloth, and the side plate is an ordinary filter plate. The material enters each filter chamber during the construction of the thrust plate. The solid particles are blocked in the filter chamber because they are larger than the pore size of the filter medium (filter cloth), and the filter flows out from the outflow hole under the filter plate. When the filter needs to be squeezed, in addition to squeezing with a diaphragm, compressed air or steam can be used to make it unobstructed in the washing port. The airflow can wash away the moisture of the filter cake, thereby reducing the moisture content of the filter cake.

(1) Filtration Method

The filtrate outflow modes are obviously flow filtration and underflow filtration.

• a. Celebrity Filtration: The exhaust gas under each filter plate has a water cone, and it flows out intuitively from the water cone.

• b. Undercurrent Filtration: There is a drainage channel hole under each filter plate. The air outlets of multiple filter plates are connected through an outflow channel and discharged from the pipe connected to the air outlet under the thrust plate.

(2) Washing Method

When the filter cake needs to be washed, there are open flow one-way washing, two-way washing, dark flow one-way washing, and two-way washing.

• a. Mingliu One-way Cleaning: The emulsion enters from the emulsion hole of the thrust plate in sequence, passes through the filter cloth, passes through the filter cake, and flows out from the filter plate without holes. The outflow from the filter plate with holes is pushed closed, and the outflow from the filter plate without holes is pushed open.

• b. Mingliu Two-way Washing: The lotion is washed twice on both sides above the thrust plate. That is to say, the detergent is washed on one side first and then on the other side, and the outlet and inlet of the lotion are diagonal, so it is also called two-way cross washing.

• c. Undercurrent Unidirectional Flow Washing: The emulsion enters the orifice plate from the thrust plate in sequence, passes through the filter cloth and filter cake, and flows out from the Wugong filter plate.

• d. Low-flow Bidirectional Washing: The emulsion is washed twice in the two emulsion suction ports on both sides above the stop plate. That is to say, the washing is first done on one side and then on the other side, and the emulsion outlet is in a diagonal direction, so it is also called low-flow bidirectional cross washing.
