Description

Adjustable energy-saving sludge press filtration device Technical Field The utility model belongs to the field of sludge treatment, and particularly relates to an adjustable energy-saving sludge press filtration device. Background In the prior art, the sewage treatment systems of most factories at present adopt a simple and fully manual sludge press filtration device, and the diaphragm plate-and-frame type press filter finishes the sludge feeding process when the sludge feeding amount is from large to small and the sludge feeding pressure is from small to large until the sludge feeding pressure reaches the allowable pressure of the press filter. The screw rod advances the mud pump power frequency operation, advances the phenomenon that the mud later stage can appear the superpressure, and former equipment can set up manual valve on advancing the import and export pipeline of mud pump, realizes advancing mud volume and advance the regulation of mud pressure through real-time manual opening valve. After the mud is fed, a squeezing pump is required to be started to squeeze and dehydrate the mud, and the squeezing process is also that the initial squeezing pressure is low, the mud filtering water quantity is large, the later squeezing pressure is high, the mud filtering water quantity is small, and the squeezing process is finished until the mud filtering water quantity is small. The working frequency of the squeezing pump runs, the phenomenon of overpressure can occur in the later stage of water squeezing, and manual valves are also required to be arranged on inlet and outlet pipelines of the mud inlet pump, and the squeezing pressure is adjusted by manually opening the valves in real time. The existing sludge treatment device cannot be automatically adjusted and controlled, manpower is wasted, and electric energy consumption is overlarge.
