Description

A kind of filter

The utility model relates to a kind of filter, and especially a kind of is the filter of filter element with the ceramic membrane.

Filter is a pipeline parts commonly used on the commercial plant.Traditional filtering generally adopts screen pack and filter cloth, perhaps adds filter mediums such as carclazyte with filter screen and filters, and this method generally is suitable for obtaining the filtration of filter cake or filtering larger particles material.In recent years, along with the development of secondary filter technology, occurred the inoranic membrane isolation technics in the world, ceramic membrane is the anisotropic membrane that is prepared from through special process with inorganic ceramic material, reaches the multichannel tubulose in a tubular form, the tube wall micropore that gathers.Under pressure, material liquid flows in the film pipe, and small-molecule substance (or water) sees through film, macromolecular substances (or solid) thus tunicle hold back and reach separations, concentrated and purification.Because ceramic membrane element is more crisp, add that existing filter hermetically-sealed construction adopts traditional pressure pad sealing, make the stressed big and unbalance stress of screen pipe, and sealing effectiveness is bad, so during the ceramic membrane filter device uses at present, the situation that leakage or ceramic-film tube fracture often occurs.

The purpose of this utility model provides the not filter of frangibility of a kind of simple in structure, favorable sealing property, screen pipe, particularly a kind of ceramic membrane filter device that is applicable to that water treatment is used.

The utility model is achieved in that whole filter is made of the housing that has orifice plate, ceramic membrane filter tube, sealing shroud, last lower platen, O RunddichtringO, O RunddichtringO baffle ring, last low head.Correspondence has some bellmouths on orifice plate on its middle shell and the last lower platen; Ceramic-film tube sealing shroud inner chamber and ceramic-film tube profile match, and an end is provided with flange, and the outer surface top and the bottom are taper, and the centre has a circumferential groove, and groove is embedded with a support ring; Ceramic-film tube is embedded in the hole of orifice plate, and with the hole between link to each other by sealing shroud, sealing is locked and is enclosed within outside the ceramic-film tube, outer surface up and down the conical surface respectively with housing on orifice plate and go up lower platen and match; Be connected by screw between last lower platen and orifice plate and compress, make the orifice plate on ceramic-film tube and last lower platen and the housing produce the sealing thrust; By the sealing of O type ring, the O type ring outside is provided with baffle ring between last lower platen and shell flange; Have clear water output on the housing, flow out for filtering the back clear water; Housing is connected with end socket up and down, which is provided with filtrate import and export up and down.

Fig. 1 is a cutaway view of the present utility model.

Fig. 2 is the enlarged drawing of ceramic-film tube hermetic unit I.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As shown in Figures 1 and 2, filter is made of housing 2, last low head 6, ceramic-film tube 1, last lower platen 11, sealing shroud 7, O type sealing ring 4, O type ring back-up ring 5, holding screw 3, pad 12 and bolt, nut 14.Its middle shell 2 is provided with orifice plate 16, has some bellmouths 10 on the orifice plate, and delivery port 15 is arranged on the housing, dewatering outlet 17, and the last lower flange of orifice plate is provided with leak hunting aperture 13; Last low head is provided with filtrate and imports and exports 18 and 8; Have on the last lower platen 11 and housing up-hole plate 16 corresponding bellmouths 9; The cavity shape of sealing shroud 7 is identical with the ceramic-film tube outer surface, the end is provided with a flange 19, restriction ceramic-film tube string is moving, top and the bottom, the outside are the conical surface 22, the middle part is provided with between two hoop flanges, 23, the two hoop flanges a groove 21, and groove is embedded with support ring 20, wherein ceramic-film tube 1 is nested in orifice plate 16 and the pressing plate 11, and is tightly connected by sealing shroud 7.When tightening screw 3, pressing plate 11 is pressed on the male cone (strobilus masculinus) 22 of sealing shroud 7 with orifice plate 16, produces extruding force, because contact-making surface is the conical surface, make sealing ring 7 produce circumferential constrictive force, lock ring on ceramic-film tube 1, thereby reach the effect of being tightly connected of 16 of ceramic-film tube 1 and pressing plate 11 and orifice plates.Can check whether sealing shroud 7 leaks by detecting hole 13 after being connected and installed.The hermetically-sealed construction at two ends is identical about the overanxious pipe of ceramic membrane.The cross sectional shape of filter can be suitable shape such as circle, polygon; The cross sectional shape of ceramic-film tube and sealing shroud with matching and taper hole can be selected circle, polygon etc. as required.

Former water is entered by bottom filtrate import 18 during work, and during through ceramic-film tube 1, wherein clear water oozes out from ceramic-film tube, flows out by the outlet pipe on the housing 15, and suspended particulate flows out from top filtrate (liquid 8 together in filtrate and the water.This process constantly circulation is carried out, thereby finishes the continuous filtration of liquid.

Ceramic membrane filter device of the present utility model has the following advantages:

1, simple in structure, be easy to processing, install and use.

2, owing to adopted with radial seal and end face seal and combine, and sealing shroud outer surface top and the bottom are the conical surface, can regulate sealing load, make favorable sealing property.

3, adopt based on radial seal, sealing shroud to the pressure of ceramic-film tube symmetrically, and because the own characteristic of tubular structure, promptly the anti-radially uniform pressure of tubular structure ability is stronger, make and not frangibility of screen pipe of the present utility model prolonged service life.

The utility model filter can be widely used in the various microporous filters, is particularly suitable for continuous precision filtration usefulness in the industries such as oil, chemical industry, environmental protection and food.The utility model product uses on the oil field reinjection water microporous filter, and is respond well, do not find sealing leak in the use, and ceramic-film tube do not occur fracture in installing/dismounting repeatedly.
