Plate and frame dehydrator

Plate-and-frame dehydrators are highly adaptable dehydrators. Another of its most striking features is the high solids content of the dewatered mud cake. The dewatering capacity is higher than that of other types of dewatering equipment. Plate-and-frame dehydrators feature the ability to retain the number of filter plates. When the sludge volume of the treatment station increases to a certain extent, the treatment capacity of the treatment station can be increased by installing a filter plate in the reserved position, so as to greatly reduce the secondary input cost. However, there are many supporting equipment for the plate and frame dehydrator, and continuous treatment cannot be realized.

The solid content of sludge entering the plate and frame dewatering machine should be greater than 1%. The main unit and frame of the plate and frame dehydrator should be designed to withstand the static load of the equipment and the dynamic load generated during the operation of the equipment. The equipment must be safe and reliable, with sufficient safety factors, and there are no problems with deflection, deformation or vibration during operation. There are many models of plate and frame dewatering machine, and factors such as sludge concentration, operation cycle, machine cost, and mud cake moisture content must be fully considered when choosing. Physical experiments must be carried out before each Filter Press is selected, and small experimental equipment is generally selected. Selection of sludge discharge method. Due to the high viscosity of the sludge water discharged from the sewage treatment station, the filter cloth oscillation or the filter cloth opening can be used to automatically discharge the sludge, so as to ensure the sludge discharge effect.
