Abstract

A microporous-membrane hollow filter plate is composed of an upper layer surface, a lower layer surface, side surfaces, short support ribs, long support ribs, through holes, support columns, an integrated cavity and a liquid outlet, wherein the liquid outlet is located in the center of the filter plate and vertically penetrates through the upper layer surface and the lower layer surface; the upper layer surface, the lower layer surface and the side surfaces form the integrated cavity; the short support ribs, 6-12 long support ribs and 6-12 support columns are arranged in the integrated cavity; the outer ends of the long support ribs are connected to the side surfaces; 1-5 through holes are formed in the long support rib; 1-7 short support ribs are arranged between two adjacent long support ribs; the outer ends of the short support ribs are connected to the side surfaces; the support columns are located between the inner ends of the long support ribs and the liquid outlet; and one end of each support column is connected to the liquid outlet, while the other end thereof is connected to the inner end of the corresponding long support rib. The through holes are formed in the long support ribs so that the effective filter area of the filter plate is increased; the integrated cavity (8) is not divided into a plurality of independent small cavities any more, thereby preventing the fracture of the surface of the filter layer due to uneven stress of the small cavities, therefore, the pressure resistance is obviously enhanced; besides, the support columns are arranged beside the liquid outlet so that the width of a filtrate flowing channel is increased, thereby being advantageous for smooth circulation of the filtrate.

Description

Microporous barrier hollow filter

Technical field

The utility model relates to a kind of filter plant, relates in particular to a kind of microporous barrier hollow filter.

Background technology

Present existing liquid filtering plate with inner bag or cavity, a kind of is to be combined with mechanical system by some parts.Part comprises upper and lower two filter and the inner bag that can pass through liquid between them or the seal washer of reinforced seal between two filters and parts of processing with filtering material that the sealing packing ring is pressurizeed.This combination filter complex structure, and sometimes owing to the sealing ring uneven poor sealing that causes of pressurized everywhere, produce without the seepage of filtering.Another kind is the disposable hollow filter of firing.The common on the market disposable hollow filter of firing is divided into two kinds.A kind of inner chamber of hollow filter is not an entire cavity; But supporting rib is set in cavity; Filter several areolas independent of each other have been divided into; Because processing technology immature causes the percent opening on integral filter plate surface and permeability uneven, speed and the permeability that causes each areola filtration be difference to some extent; Each areola bears the pressure inequality, bears the big place of pressure and just is prone to caused the filter plate skin breakage by pressure break, produces without the seepage of filtering.Brace rod reduces the filter area in the cavity, has reduced the flow of filter.In addition, the liquid outlet of this hollow filter is located on the circumference of its center circle center hole, and liquid outlet channel is the part of brace rod in the cavity, and the liquid outlet passage of centre bore is irregular, easy to be stopped up, and influences the flow of liquid mistake.Adopt some columniform support columns in the cavity of another kind of hollow filter; Though improved the little shortcoming of brace rod formula filter filter area to a certain extent; But because processing technology is immature; The percent opening and the permeability on integral filter plate surface are uneven, the phenomenon of filter plate skin breakage still can often occur, produce without the seepage of filtering.

Summary of the invention

In order to solve the problems of the technologies described above; The utility model provides the microporous barrier hollow that a kind of filter area is big, anti-pressure ability is strong filter; Be made up of last aspect (1), subsurface (2), side (3), short brace rod (4), long support muscle (5), through hole (6), support column (7), entire cavity (8), liquid outlet (9), it is characterized in that liquid outlet is positioned at the central authorities of filter and vertically runs through aspect and subsurface, last aspect, subsurface and side surround entire cavity; Be provided with short brace rod, 6-12 root long support muscle and 6-12 root support column in the entire cavity; The outer end of long support muscle is connected with the side, and the long support muscle is provided with 1-5 through hole, is provided with the short brace rod of 1-7 root between two adjacent long support muscle; The outer end of short brace rod is connected with the side; Support column is between the inner and liquid outlet of long support muscle, and the one of which end is connected with liquid outlet, and the other end is connected with the inner of long support muscle.

Described upward aspect is the micro porous filtration layer, and subsurface is micro porous filtration layer or non-micro porous filtration layer, and the side is micro porous filtration layer or non-micro porous filtration layer.

The beneficial effect of the utility model is: the long support muscle is provided with through hole; Increased the effective filtration area of filter; Entire cavity no longer is divided into several independently areolas, the phenomenon of the filter course skin breakage that can not occur causing because of the areola unbalance stress, and anti-pressure ability obviously strengthens; Liquid outlet is other to be provided with support column, has strengthened the width of filtrate flow circulation passage, is beneficial to the smooth and easy circulation of filtrating.
