Problems solved by technology

[0002] The core plate is the main filter element of the filter press. At present, the core plate is generally formed by pressing or integral injection molding. Due to the large thickness of the core plate, the cooling time is very long, and there will be honeycomb-shaped pores inside, which will affect the core plate. The strength, the processing efficiency is very low, and affects the filtration efficiency

Embodiment Construction

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Such as Figure 1-2 As shown, the present embodiment provides a frame-type diaphragm core plate, which includes a rectangular core plate 1 body, the front and back of the core plate 1 are provided with an annular area 2, the inner side of the annular area 2 is the inner Area 3, the outer side of the annular area 2 is an edge area 4, the four corners of the edge area 4 are provided with liquid outlet holes 5, and the inner area 3, the annular area 2 and the edge area 4 are all provided with different distributions and shapes. Several different grooves 6. figure 1 Only 1 / 4 of the figure shows the distribution of the grooves, which is to make the whole outline clearer, and does not mean that there are no grooves in the other 3 / 4. In addition, the groove distribution at 3 / 4 is the same as that at 1 / 4.

[0016] The grooves in the inner area 3 are square grooves, and...

Abstract

The invention discloses a framed diaphragm core plate, comprising a rectangular core plate body; both the front and back of the core plate are provided with circular areas, an inner area is arranged within each circular area, a peripheral area is arranged outside each circular area, each peripheral area is provided with a liquid outlet at each of its four corners, and each of the inner areas, circular areas and peripheral areas is provided with a plurality of cavities different in distribution and identical or different in shape. The framed diaphragm core plate has the advantages that the cavities are added to the original thick wall parts so that the whole core plate has uniform thickness and cooling time uniformity is guaranteed, and the problem that production efficiency is low due to long cooling time of the thick wall parts is effectively avoided; the cavity parts can save the material by above 20% so that product cost is effectively reduced; strength loss due to inner pores can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of filter press filtration, in particular to a frame-type diaphragm core plate. Background technique [0002] The core plate is the main filter element of the filter press. At present, the core plate is generally formed by pressing or integral injection molding. Due to the large thickness of the core plate, the cooling time is very long, and there will be honeycomb-shaped pores inside, which will affect the core plate. The strength, the processing efficiency is very low, and affects the filtration efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a frame-type diaphragm core plate. The existing heavy core plate is designed into a grid shape, and the cooling thickness is greatly reduced while ensuring the original strength, effectively preventing internal air holes At the same time, it can save about 20% of the material and reduce the pr...
