Abstract

A filtering device comprises a filtering body, two end flanges which are used for connecting peripheral pipelines and are connected with the two ends of the filtering body, wherein the filtering body comprises a shell, at least one filtering plate which is densely distributed with a plurality of filtering holes, a sealing component which is used for sealedly installing the filtering plate on the shell, a door flange which can enable each filtering plate to be installed insertedly is arranged on one side of the shell, guiding grooves which can enable each filtering plate to move is arranged in the cavities of the shell. Since a straight hole-plate filtering structure with side doors is adopted by the filtering device, thereby a slid of the filtering structure in an existing pipeline is smartly changed into a door when disassembling and cleaning, and processes of examine and repair, assembly and disassembly are all can be carried out on one side, no need of relating to the end flanges which are connected with outer connecting pipelines, the filtering device has the advantages of very simple and convenient operation, easy manufacture and strong practicality.

Description

A kind of filter

Technical field

The utility model relates to the filter in the water for industrial use, particularly a kind of middle filter of water for industrial use pipeline that is installed on.

Background technology

The ducted filter of existing water for industrial use as shown in Figure 1, its by two Taper Pipes 3 ', two end flanges 4 ', two bolted spacer flangers 2 of usefulness ', two stripper rubbers 5 ' and be clipped in the filter 1 of sealing offset plate 5 ' centre ' form, whole filter leans on two end flanges to be connected in the water for industrial use pipeline.When the filter, be blocked in the screen pipe inlet side at water, can influence the flow of water when impurity reaches some in the water, thereby influence production target, therefore, need this moment to clear up greater than the impurity in filter filtering holes aperture.Then need during cleaning the bolt of spacer flanger is backed out, pull out filter and stripper rubber, again filter and stripper rubber are turned back to the original place after cleaning is good, tighten the bolt of spacer flanger, guarantee the sealing of stripper rubber.Water-tight for guaranteeing, to press very tightly between each flange, the rubber skin produces moderate finite deformation, and pipeline almost is again a rigidity, and dismounting is very inconvenient.When stripper rubber and filter especially are installed, need pry open two companion flanges that filter and stripper rubber place are housed, make between flange and maintain a certain distance, and guarantee two companion flange essentially concentrics, stripper rubber and filter could be turned back to the original place (they also must with the flange essentially concentric, otherwise dislocation can reduce the discharge area of pipeline, or makes bad the causing of sealing leak).Simultaneously, the seam between two spacer flangers is very little, and the impurity of the inside is difficult to clean out.Clearing times is decided by impurity in the water, the factory that has, a class will clear up once, and processing time length directly influences production efficiency and product quality, and the therefore existing installation that is contained in the filter of the filter in the pipeline has become anxious problem to be solved with the cleaning that leaches impurity.

Summary of the invention

The purpose of this utility model is to be not easy the cleaning problem at impurity in difficult dress of filter that has the filter existence that is installed in the pipeline now and the filter, invents the filter that a kind of filter is easy for installation, impurity is cleared up easily.

The purpose of this utility model is achieved through the following technical solutions:

A kind of filter, it is characterized in that comprising two end flanges that are used to connect peripheral conduits of filtering body, being connected in filtration body two ends, wherein said filtration body comprises housing, at least one filter that is densely covered with many filtering holes, be used for the black box of filter sealing device on housing, described housing one side is provided with the door flange that can supply each filter to pack into with pulling and pushing, and the housing inner chamber is provided with can be for the gathering sill of each filter motion.

Wherein, above-mentioned black box comprises that being fixed in covering of filter outer end places blind flange, the sealing offset plate between door flange and blind flange on the above-mentioned door flange, is used for fastener that blind flange, sealing offset plate, door flange are connected and fixed, wherein said fastener be arranged at flange hole or the screw on a flange and the blind flange and be placed through flange hole or screw in screw rod one nut check assembly.

The utility model is because the through type orifice plate filtration that adopts side to open the door, the structure that an existing slit becomes a sect is cleaned in the dismounting that will have ducted filtration dexterously now, in maintenance, installation, unloading process, all only need carry out in a side of filtering body, do not need to relate to the end flanges that is connected with external pipe, operate very simple and convenient.And it is easy, practical that the utility model is made.

Describe basic structure of the present utility model in detail below in conjunction with accompanying drawing:

Description of drawings

Fig. 1 is a filter structure schematic representation of the prior art;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is a sectional structure schematic diagram of the present utility model.

The specific embodiment

As Fig. 1～shown in Figure 3, a kind of filter described in the utility model, comprise two end flanges 2 that are used to connect peripheral conduits of filtering body 1, being connected in filtration body 1 two ends, wherein said filtration body 1 comprises housing 11, at least one filter 12 that is densely covered with many filtering holes, be used for the black box of filter 12 sealing devices on housing 11, described housing 11 1 sides are provided with the door flange 13 that can supply each filter 12 to pack into with pulling and pushing, and housing 11 inner chambers are provided with can be for the gathering sill 14 of each filter 12 motion.Wherein, above-mentioned black box comprises that being fixed in covering of filter 12 outer ends places blind flange 15, the sealing offset plate 16 between door flange 13 and blind flange 15 on the above-mentioned door flange 13, is used for fastener that blind flange 15, sealing offset plate 16, door flange 13 are connected and fixed, and wherein said fastener is to be arranged at flange hole or the screw on a flange 13 and the blind flange 15 and to be placed through flange hole or screw rod one nut check assembly that screw is interior.Its installation process is that hand is taken filter flange handle, filter 12 end alignment gathering sills 14 are inserted inwards, Fig. 2 is a position in the slotting process of dress, continue to insert inwards, filter 12 blind flanges 15, seal gasket and door flange 13 are sticked, with screw filter 12 blind flanges 15 and door flange 13 are tightened, guaranteed the sealing property of sealing offset plate 16.Filter 12 installations in this maintenance process promptly come to an end, and are therefore, very simple and convenient.Metaphor visually, its similar slide valve, what slide valve stopped is liquid, and what stop is impurity herein.
