Technical field:
The utility model relates to the technical field of filter press equipment, in particular to a filter cake blowing structure based on a filter plate of a filter press.
The background technology is as follows:
The filter press is a main filtering device in the solid-liquid separation industry, materials enter a filter chamber through a central feed hole of a filter plate during filtering, particles in the materials are trapped by filter cloth arranged in the filter chamber to form a filter cake, filtrate is discharged from four corner liquid outlet holes of the filter plate, and the purpose of solid-liquid separation is realized.
The utility model comprises the following steps:
The utility model aims to provide a filter cake blowing structure based on a filter plate of a filter press, which solves the problem that a filter cake cannot automatically fall off due to high water content of the filter cake in a filter press in the prior art, and mainly solves the technical problem that the viscosity of the filter cake is high due to high water content of the filter cake.
The utility model relates to a filter cake blowing structure based on a filter plate of a filter press, which comprises a filter plate assembly, wherein filter cloth is arranged in the filter plate assembly, the filter cloth divides an inner cavity of the filter plate assembly into a filter cake cavity and a filter water cavity, an annular flow passage is arranged on the filter plate assembly, a plurality of flow holes are uniformly distributed on the inner wall of the filter water cavity, the flow holes are communicated with the filter water cavity, a water outlet pipe is arranged on the filter plate assembly, a blowing pipe is arranged on the water outlet pipe, and the blowing pipe is connected with a compressed air pipeline.
Further, the filter plate assembly is formed by buckling a filter plate frame and a filter plate groove, filter cloth is arranged in the filter plate frame, annular flow grooves are formed in the outer edge of the filter plate groove, and the flow grooves are buckled on the filter plate frame to form the flow channels.
Further, a sealing ring is arranged between the filter plate frame and the filter plate groove, and the sealing ring is used for sealing the launder.
Preferably, all of the flow holes are centrally symmetric about the center of the filter plate assembly, and the axes of the flow holes do not intersect the center of the filter plate assembly.
Preferably, the inclined direction of the flow hole is directed toward the flow direction of the air blowing in the flow passage.
Preferably, a plurality of support pins are arranged in the filter plate grooves, and the support pins are used for supporting the filter cloth.
The utility model has the beneficial effects that the structure is simple, the filter plate assembly is designed into a split structure, the annular flow channel is designed on the filter plate assembly, and the vortex-arranged flow holes are designed, so that filtered water can be rapidly discharged, the pressure maintaining time of filter pressing is shortened, the water content is reduced, meanwhile, the blowpipe is designed, the blowback is performed through the flow channel and the flow holes, the water content is reduced, the filter cake is automatically separated from the filter cloth, and the normal operation of filter pressing operation is ensured.
Description of the drawings:
FIG. 1 is a front view of the present utility model;
