Problems solved by technology

[0002] The current vertical filter press basically uses elastic diaphragm extrusion to pressurize the slurry to be filtered to squeeze out the liquid through the second filter cloth to obtain a filter cake. However, due to the limitation of the diaphragm material, the pressure is usually It is not high, and the effect is not ideal for pressure filtration of some difficult-to-filter slurries (such as sludge, fruit pulp and other colloids or colloid-like slurries, especially activated biological sludge)

Abstract

The invention relates to a filter pressing assembly, which comprises a base plate, a through hole area in the middle of the base plate, a piston wall which surrounds the through hole area and extends downwards is arranged on the bottom face of the base plate, and a piston top plate, a channel plate and first filter cloth are sequentially arranged at the bottom end of the piston wall from top to bottom; the piston top plate is provided with a second pipe used for guiding fluid into a groove and a fourth pipe used for discharging the fluid in the groove, the outer surface surrounding the piston wall is sleeved with a piston sleeve, and the lower surface of the first filter cloth and the inner surface of the piston sleeve define a filter pressing cavity, and a first pipe for leading in slurry to be filtered is arranged in the filter pressing cavity. The invention also relates to a filter press comprising the filter pressing assembly and a filter pressing method. The product has the advantages of high operation pressure, high filter pressing speed, low liquid content of a filter cake, reliable structure, convenience in automatic operation and the like, and is particularly suitable for filter pressing of systems difficult to filter, such as activated sludge and pectin.

Description

technical field [0001] The invention relates to the field of filter press treatment, in particular to a filter press assembly, a filter press part including the filter press assembly, a filter press including the filter press part, and a filter press method using the filter press machine. Background technique [0002] The current vertical filter press basically uses elastic diaphragm extrusion to pressurize the slurry to be filtered to squeeze out the liquid through the second filter cloth to obtain a filter cake. However, due to the limitation of the diaphragm material, the pressure is usually It is not high, and the effect of pressure filtration on some difficult-to-filter slurries (such as sludge, fruit pulp and other colloids or colloid-like slurries, especially activated biological sludge) is not ideal. In addition, the degree of automation of filter press equipment is getting higher and higher. Therefore, there is still a need for improved filter press equipment capab...
