Fully automatic stainless steel filter cake layer automatic slag discharge candle filter machine "Price, quotation, manufacturer"

The fully automatic stainless steel filter cake layer automatic slag discharge candle filter adopts PLC touch screen control technology and good process design to achieve fully automatic control of the four key points of filter cake layer filtration, comprehensively solving the technical problems of filter cake layer filtration.

The candle filter combines multiple porous filter elements in a closed container, and filters the filter cloth (or other filtering medium) on the outer jacket of the filter element. During filtration, a pump is used to send the slurry into the filter. The liquid in the slurry passes through the filter medium and enters the center of the porous filter element, where it is collected and discharged at the clear liquid outlet. Before the candle filter forms a filter cake, the discharged "clear liquid" returns to the raw slurry inlet and is sent to the filter for circulating filtration until the candle filter forms a filter cake (which can meet the filtration requirements), providing a signal to control the clear liquid to no longer circulate. The clear liquid is sent to the next process for normal filtration through a three-way valve. After a period of normal filtration, when the filter cake on the porous wick reaches a certain thickness, a signal is provided to control the feeding (stop), and then the residual liquid in the filter is drained. After draining, a signal is provided to control the blowback port (compressed air, nitrogen or saturated steam) to blow back, causing the filter cake to fall off. After a certain period of blowback, the blowback is stopped and a signal is provided to open the filter slag discharge port for slag discharge. After the slag discharge is completed, the slag discharge port is closed, returning to the initial state before filtration and preparing for the next round of filtration.
