Embodiment 1

[0030] Such as figure 1 , 2 , 8, the sewage diversion filter device includes at least two diversion plates 1 and a diaphragm 10 used in conjunction with each other, wherein the diversion disc 1 and the diaphragm 10 are adjacent to each other, and the number of diversion discs 1 One more than the number of diaphragms 10, the guide plate 1 is a disc with a center hole 7 in the guide plate, and a boss is also arranged on the surface of the guide plate 1. On the guide plate 1 There are also two diversion slits 3 , and two orientation slits 13 matching the diversion slits 3 are arranged on the diaphragm 10 . There is a ring of protruding teeth 8 arranged along the radial direction on the outer side of the hole 7 of the above-mentioned deflector plate. The protruding teeth 8 are fixed on the inner edge of the deflector plate 1, and gaps are provided between the protruding teeth 8. The gaps are diversion gaps. , the setting positions of the upper and lower sides of the protruding t...

Embodiment 2

[0035] Such as image 3 , 4As shown, the difference between this embodiment and Embodiment 1 lies in that the bosses are convex strips 9 , and the convex strips 9 are arranged on both sides of the deflector plate 1 in a certain arc in sequence. The convex line can better guide the dirty liquid, further reduce the pressure loss of the dirty liquid in the flow process, make better use of production resources, and reduce production loss; at the same time, the contact area between the convex line and the diaphragm Larger, which further reduces the force on the surface of the diaphragm, better avoids the damage of the diaphragm during use, improves the service life of the diaphragm, reduces the maintenance frequency during use, and greatly improves the use effect.

Abstract

The invention discloses a sewage flow-guiding and filtering device which includes at least two flow-guiding disks and a membrane piece which are matched with each other. Each flow-guiding disk is a disk with a central position being provided with a flow-guiding disk central hole. A projecting bench is disposed on a surface of each flow-guiding disk. Each flow-guiding disk is provided with two flow-guiding gaps. Two directing gaps matched with the flow-guiding gaps are disposed on the membrane piece. The two flow-guiding gaps are symmetrically disposed on the flow-guiding disk. The flow-guiding gaps are inclined slide pathways of which upper parts and lower parts are radially stretched and are protruded in axial opposite directions and an oblique range is 30-60 degrees. Each upper slide pathway and each lower slide pathway are respectively disposed on an upper surface of the flow-guiding disk and a lower surface of the flow-guiding disk. By means of the sewage flow-guiding and filtering device, a pressure loss is further reduced and sewage purification efficiency is increased. Meanwhile, a use effect is improved. The device has a better recognition degree on market, can push industrial development and can enhance competitiveness of enterprises.

Description

technical field [0001] The invention relates to a purification device, in particular to a sewage diversion filter device for purifying sewage. Background technique [0002] Although the traditional spiral-wound membrane has a high filling area density, the system application has high requirements on the influent water quality and complicated pretreatment conditions. Because the organic pollutants, inorganic scaling substances and suspended particle impurities in the high-concentration fluid will easily block the screen of the membrane column, resulting in frequent shutdown and cleaning of the system, which will reduce the life of the membrane column and even fail to operate normally. [0003] The existing disc-type membrane column solves the above-mentioned anti-pollution problem of the membrane column. In fact, there is still a special problem with the disc membrane column, which is that the disc membrane column used for nanofiltration, ultrafiltration and microfiltration ...
