Task of the present utility model provides the adjustable filter of a kind of strainer, and its utilizes by the filtrate body and enters the height that pressure in the main body is automatically adjusted strainer, improves filter quality easily and effectively and increases filtration capacity, and make backwash simpler easily.
For finishing above-mentioned task, the following porous plate that the utility model is arranged in the main body is connected with the suspension that is arranged on porous plate top by connecting elements, and descends porous plate and suspension to move up and down.When in main body, injecting liquid by the import on the main body, suspension is moved upward by buoyancy function, it can drive down by connecting elements, and porous plate also moves upward thereupon, forcing up and down, the fibre bundle between the porous plate vertically compresses, make strainer narrow down with the pressure increase of liquid, impel the density of fiber filtering to increase like this, thereby improve the quality that leaches liquid.This process does not change owing to filtering the cross section, so the flow velocity of filtrate does not have much changes substantially.
Described suspension can be made into hollow hemispherical, and its sphere is towards top.Suspension can be made by the rigid material of thin-walled.
Bottom in the described main body also is equipped with 2～6 supporting rods, and this supporting rod passes up and down two porous plates and extends and go up porous plate one segment distance, and it can be used to the support suspension member.
Described connecting elements between the porous plate up and down can be made of chain link, and the outside of chain link is provided with slender rectangular tube, and this pipe fitting can make chain link and fibre bundle completely cut off.
Described main body also is provided with passage and peep hole on the side.
Because the utility model adopts a suspension and is attached thereto the porous plate moving up and down that connects, when injecting liquid in the main body, under the powerful buoyancy and pressure effect of suspension and following porous plate liquid body, the loose fibres filtering layer is in compaction state to a certain degree when making original state, it has increased the density of filtering layer, assurance leaches the purity of liquid, and the speed of filter liquide does not change comparatively fast owing to filtering the cross section.In addition, when the pressure of liquid in the main body disappeared, fibre bundle was straightened under elemental effect and promptly is in loose condition (of surface), at this moment is beneficial to very much backwash.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is a cross-sectional view of the present utility model;
Accompanying drawing 2 is structural representations of following porous plate.
Fig. 1 has provided the utility model overall structure.Wherein I partly be left part show be duty the time main body 1 internal structure, what II partly was that right part shows is main body 1 internal structure of off working state or backwash state, I portion and II portion are axial symmetric figures.The bottom of main body 1 is provided with the delivery port 12 that inlet opening 11 and top are provided with, and inlet opening 11 generally is for being flowed into by the filtrate body, flowing out through delivery port 12 through filtering layer then again.Two ends were by cylinder or other body of annular sphere sealing about main body 1 can be made by steel plate or other rigid material.Cylindrical peripheral in main body 1 also is provided with passage 13 and peep hole 14.Peep hole 14 is the function situations of observing each parts in the main body 1 for the operator, and passage 13 is to blow gases at high pressure for the operator by this hole in main body 1, specifically uses when backwash.Be provided with suspension 2 in the main body 1, go up porous plate 3 and following porous plate 4, and several critical pieces such as the fibre bundle that is used for impurity screening 5 of installing between two porous plates.Last porous plate 3 and following porous plate 4 are made and main body 1 inwall similar shapes, and go up the top that porous plate 3 is fixed on main body 1, and it is immovable, can moving axially along main body 1 and descend porous plate 4 to be arranged on the bottom of main body 1 and to be subjected to external force to do the time spent.So-called porous plate is to be drilled with a plurality of holes on the plate face, with for liquid can be on this hole be in main body 1 current downflow.The two ends of fibre bundle 5 are separately fixed on two porous plates (3,4).
From the II portion of Fig. 1 as can be seen, when not having liquid in the main body 1 or enough do not make down enough liquid when moving on the porous plate 4, fibre bundle 5 is similar to vertically, and its density is less.And find out from the I portion of Fig. 2, when moving certain distance on the porous plate 4 instantly, fibre bundle 5 is in irregular compaction state, this moment, the density of fibre bundle 5 was bigger, and the size of density is with moving distance dependent on the following porous plate 4, move distance promptly and rise greatly, the density of fibre bundle 5 is just big more, and the effect of filter liquide is just good more.The action of following porous plate 4 is mainly finished by suspension 2 except that the pressure of liquid body.Middle part at suspension 2 and following porous plate 4 is equipped with a connecting elements 6, this connecting elements can be made of chain link, and be provided with an elongated pipe fitting 7 in the outside of chain link, it can make connecting elements 6 is that chain link and fibre bundle 5 is isolated, when preventing that fibre bundle 5 in working order and chain link be intertwined.Suspension 2 can be made into hollow hemispherical, and sphere is towards top, and it can be made by the rigid material of thin-walled.The action of suspension 2 is mainly finished by buoyancy of liquid, when in main body 1, passing through water inlet 11 injection liquid, along with liquid level increase near suspension 2 time, suspension 2 moves up under liquid buoyancy and pressure effect, thereby driving down by connecting elements 6, porous plate 4 moves up, when filling with water in the main body 1, this moment, loam cake was approached at the top of suspension 2, it is the position shown in the I portion, following porous plate 4 becomes fibre bundle 5 into random compaction state, forms certain thickness filtering layer.Because the filtering layer that fibre bundle 5 forms is that axial distance changes, and does not radially change, so for not produced much influences by the flow velocity of filtrate body.When the water in the main body 1 was discharged, suspension 2 and following porous plate 4 returned to the origin-location, i.e. position shown in the II part, and fibre bundle 5 fully opens, and can carry out backwash to this filter at this moment.At first, make liquid or aqueous reflux, blow the gas that certain pressure is arranged by passage 13 in main body 11 then, make fibre bundle 5 be in the vibration state, the pollution medium on the favourable removing fibre bundle 5 makes the more thorough of flushing.
