As a solid-liquid separation of machinery and equipment, filter presses are now most commonly used in industrial wastewater and waste treatment, as we all know, over the years, with the strengthening of the national monitoring of environmental pollution in factories, more and more environmental protection equipment and ideas into the mainland production plants, of which the filter press is the most widely accepted, because this device is mainly through the control of pressure, to achieve the internal flow of filtered material, to achieve the flow of the filter. The main working principle of this equipment is simple, the production technology is not complicated, and the cost is low, so it is welcomed by many people, and among the many models of filter presses, the chamber filter press is more in line with people’s ordinary life because of its form. Among the many models of filter presses, the chamber filter press has the largest share in the market because its shape is more in line with the needs of people’s ordinary life. In fact, the chamber filter press is just a class of filter presses, although the working principle of everyone is basically the same, but the implementation, or a little difference. So we follow the operation process of the chamber filter press to execute it correctly, it will be fine. First is the start-up procedure. What I want to say here is that before starting the procedure, the preparatory work should be done. This preparation work is to hold the pressure of the chamber filter press, pull the filter plate and clean the filter cloth. After the preparatory work is in place, the oil supply pump can be started and the oil cylinder will work to produce the required pressure state of the chamber filter press, and then the motor will stop working. The next step is to start feeding and filtering. The key part here is to check whether the pipes are smooth. Because the feeder has to transport the solid-liquid mixture to the filter chamber for solid-liquid separation. So the pipeline must be smooth, otherwise the consequences can be unimaginable. When the filtration chamber is full, the supply of raw materials should be stopped. Finally, after the end of filtration, the liquid is discharged, and the filter slag, which is attached to the filter plate, should be removed in time, and the filter tank should be cleaned up, so that the next work can be carried out smoothly. If the above steps are strictly followed, the whole chamber filter press will work smoothly and the operator will feel relaxed because of the normal use of the chamber filter press.
