Drum paper belt filter is composed of shell, deceleration motor, driving device, screen assembly, sealing drum, filter cloth, electric control system and other parts. The filter cloth is laid flat in the screen assembly. Above, a liquid pool is formed under the seal of the sealing drum. The cutting fluid with impurities is buffered and uniformly falls onto the filter cloth. Up. Cutting fluid under the action of heavy force through the filter cloth into the clean liquid tank, impurities greater than 40 microns are intercepted by the filter cloth, with the accumulation of impurities trapped on the surface of the filter cloth, the surface formed a filter cake layer, the filter cake layer is also involved in filtering, effectively improving the filtering accuracy of the cutting fluid. When the filter cake layer becomes thicker and thicker, the transmission speed of the cutting fluid gradually decreases, and the liquid level in the liquid pool gradually increases. When the liquid level rises to the set value, the signaling mechanism sends a signal, the gear motor drives the screen assembly to drive the filter cloth - to move into a new filter cloth, and the cutting fluid in the liquid pool passes through the filter cloth newly entered, and the liquid level in the liquid pool decreases. The sending mechanism stops sending signals, the deceleration motor stops running, and the filter cloth and impurities out fall into the waste cloth box and enter the next work link.
Drum paper tape filter is divided into a variety of basic types according to the processing capacity, suitable for different working conditions of cutting fluid filtration. Each basic type of dimensions can be flexibly designed according to the requirements, combined with our experience, by adjusting the relevant parameters to meet the requirements of various working conditions.
