Working principle The company of the belt vacuum filter, the working principle of the filter company is: the vacuum suction filtration method is used for the solid-separation of the slurry, the vacuum is formed on one side of the filter medium, and the slurry to be separated is normal pressure on the other side Therefore, a pressure difference is formed on both sides of the medium. Under the effect of the pressure difference, the liquid flows through the medium to the vacuum side, and the solid is trapped on the filter cloth. At the beginning of the filtration stroke, the vacuum switching valve opens the vacuum and connects the moving vacuum chamber through the liquid collection pipe to form a vacuum in the vacuum chamber; the slurry is evenly distributed on the filter cloth by the feed pump through the distributor, due to the vacuum suction, the filter cloth is closely attached The filter tray, the slurry is filtered by suction. The filter cloth is driven by the driving roller, and the vacuum chamber is driven by the reciprocating cylinder. The filter cloth and the vacuum chamber advance at the same speed and in the same direction until the operation of the vacuum chamber meets the contact of the machine-controlled stroke valve or the magnetic conductor in the reciprocating cylinder reaches the limit magnetic end. A magnetic signal is generated, and the vacuum switching valve operates to close the vacuum. The vacuum chamber is connected to the atmosphere first, the filter cloth is no longer in close contact with the filter disc, and then the reciprocating cylinder drags the vacuum chamber back to its original position. The filter cloth is driven forward by the driving roller. When the vacuum chamber returns quickly until it touches the other end of the machine-controlled stroke valve contact, the vacuum switching valve acts again to open the vacuum. The reciprocating cylinder drives the vacuum chamber and the filter cloth to move forward together. The second vacuum suction filtration process begins, and so on. get on.
