Abstract

The utility model relates to a fiber filter cartridge with adjustable density. Both ends of a fiber bundle cartridge are respectively fixed to a fixed disc and the lower part of a rotary and movable disc by clamping rings, a multihole inner tube is installed in the fiber bundle cartridge, both ends of the multihole inner tube are inserted in the central holes of the fixed disc and the rotary and movable disc, and then combined body is inserted in an outer cartridge. The bottom of the cartridge is fixed between the inner tube and the outer bottom, the fixed disc is fixed on the tube cartridge, the fixed disc is fixed to the bottom of the cartridge, a sealing seat sleeve is sheathed on a shaft rod of the rotary and movable disc, a sealing ring is installed in a slot of a nut sleeve which is screwed on the sealing seat, and a threaded rod of the rotary and movable disc is screwed in an internal screw thread hole of the nut sleeve. The utility model has the advantages of high filtration precision and convenient filtration and cleaning.

Description

The fiber filter tube of adjustable density

The utility model belongs to the design and the manufacturing technology field of filter.Be used for the filtration of fluid media (medium)s such as water or air.

At present, the cartridge filter that uses in this area (device), its filtering material have screen cloth, fibrofelt, porous ceramics, porous sintered, porous plastics etc.Its pluses and minuses of these screen packs (device) are: the regeneration of screen cloth class cartridge filter easy cleaning, but filtering accuracy is low, should not use in a lot of occasions.Porous class filter cylinder filtering accuracy height, the scope of application is wide, but easily stops up, and is difficult for cleaning and regeneration, thereby has increased use cost.

The purpose of this utility model is to provide a kind of new cartridge structure, i.e. the fiber filter tube of adjustable density.Just, when being in the filtration state, density is heightened, to guarantee enough precision.When being in the cleaning state, density is turned down, so that filter residue is cleared out, makes filter cylinder regeneration.This filter cylinder makes high accuracy filter cylinder cleaning and regeneration become possibility.

The technical solution of the utility model is: with a certain amount of isometric fibre bundle, its two ends are separately fixed on two disks, make fibre bundle form a cylindrical shape.Pass fiber bundled tube center and two disc centre with a pipe again.One of them disk is fixed on the pipe, and another disk then can and move along the central tube rotation.So just can realize the action of adjustable density.Promptly work as movable disc and be rotated counterclockwise, the movable disc spiral rises, and fibre bundle is tightened up and is wrapped on the central tube, at this moment fibre bundle density height; When movable disc turns clockwise, the movable disc spiral descends, and fibre bundle loosens and gets back to non-winding state, and at this moment fibre bundle density is low.

Structure of the present utility model as shown in drawings

Below in conjunction with accompanying drawing planform of the present utility model is done and to be specified

Accompanying drawing is the monotubular structure of filter schematic diagram that constitutes with the utility model

13-dividing plate 14-handwheel 15-exported the 16-import at the bottom of 1-rotated mobile disk 2-screw sleeve 3-sealing ring 4-seal receptacle 5-filter body 6-fastening ring 7-porous urceolus 8-porous inner tube 9-fiber bundled tube 10-fastening ring 11-fixed disc 12-tube

The adjustable fiber filter tube of packing density in filter body 5.It is made up of porous inner tube 8, porous urceolus 7, fiber bundled tube 9, fixed disk 11, the mobile disk 1 of rotation, seal receptacle 4, sealing ring 3 and screw sleeve 2, fastening ring 6,10.

One end of fiber bundled tube 9 is fixed on the fixed disc 11 with fastening ring 10, and the other end is fixed on the bottom that can twine tension or loosen the mobile disk 1 of rotation of fiber bundled tube 9 with fastening ring 6.Porous inner tube 8 is contained in the fiber bundled tube 9, and insert in the centre bore of fixed disc 11, the mobile disk 1 of rotation at two ends.So far, formed assembly and inserting in the porous urceolus 7.The tube back welding connects and is fixed between porous inner tube 8 and the porous urceolus 7.At the bottom of fixed disc 11 is fixed on tin on 12.Rotate the integral body that mobile disk 1 is made up of disk, axostylus axostyle and screw rod three parts.Seal receptacle 4 is enclosed within on the axostylus axostyle of the mobile disk 1 of rotation.Sealing ring 3 is contained in the groove of screw sleeve 2.Screw sleeve 2 usefulness external thread rotaries are combined on the seal receptacle 4.The screw rod of rotation displacement disc screws in the internal thread hole of screw sleeve 2.

Said structure is formed the fiber filter tube of a complete adjustable density.

The filter process of filter is: at first be rotated counterclockwise handwheel, rotation displacement disc spiral is risen, at this moment fibre bundle is tightened up and twines on inner pipe.Medium enters from import 16, passes high-density fiber bundle and urceolus by inner core, flows out from exporting 15 at last, and medium promptly is filtered.

The cleaning process of filter is:

Handwheel is turned clockwise, rotation displacement disc spiral is descended, at this moment fibre bundle loosens and falls back on non-winding state, and fibre bundle density reduces.Backwash medium (water or air etc.) flushing fibre bundle, filter residue then is easy to by eccysis.

Can form monotubular or many filters with the utility model, its control mode can be manually, also can be automatic.

The utility model has the advantages that, rational in infrastructure, the filtering accuracy height, it is all convenient to filter with cleaning.
