Description

Fiber bundle filter by mechanical back washing and compressing

The utility model patent relates to a kind of new liquid filter, particularly relates to the improvement of fiber filtering filter capable of washing.

Chinese patent CNB5200039U " fiber-ball filter media " has proposed a kind of special fibre ball made from fiber, and this fiber-ball filter media is widely used in the water treatment, obtains effect preferably.Undertaken by Chinese patent CN2050880U " X well liquid filter " with the concrete filter of implementing of fiber-ball filter media.Its backwash is by mechanical agitation or air water associating backwash.Because fibrous nodules is by hand or mechanical ligation, ligation position dirt is difficult for being cleaned in backwash, influence filtering accuracy thereby form the sand core, and can produce fiber or diffusing ball phenomenon makes the filtrate inefficacy in backwash repeatedly.

A kind of novel filter plant that Chinese patent CN87100467A " filtration method by mediums and equipment " is proposed, its filtrate is made up of multifibre, filtrate compression, loosening is fibre bundle is carried out radial compression and to realize by adding press mold.It has exempted the technology of fibrous nodules ligation trouble, and has eliminated the sand core and fallen phenomenons such as fiber, diffusing ball.But add press mold in this filter is consumable accessory, influences functional reliability, is radial compression by what, the filter area of actual filtration device is much smaller than the filtering tank sectional area, and increased pump or source of the gas and valve with adding press mold pressurization, increased operation easier, and backwash is not thorough.

Task of the present utility model provides a kind of fiber bundle filter, and it can not only make the contained suspension particle diameter of water outlet below 1.5 μ m, and effluent quality is good, and retaining power is big, the filtering velocity height, and backwash is convenient and thorough.

The purpose of this utility model is achieved in that cylindrical shell, loam cake, lower cover and the bearing with bolted on connection constitutes the jar of vertically placing, at loam cake with cover down the mouth of a river is up and down arranged respectively, (decelerator can be planetary reduction gear, cycloidal-pin wheel decelerator, also can be other decelerator by motor and decelerator one of loam cake installation.) rotating mechanism formed, driving the dish of going up of a positive and negative rotation of energy, rotating mechanism and last dish are connect by axle, and (seal box divides two kinds of upper and lower seal boxes, can be that rubber seal also can be other sealing between axle and loam cake seal box.) prevent that pot liquid from leaking, last dish be it is characterized by multifibre, the jar bottom is installed with a mechanism that can make the lifting that lower wall moves up and down, it is made up of motor, worm type of reduction gearing, screw rod.

When filtering, start elevating mechanism earlier, lower wall is risen by certain compression ratio compressing fibre bundle, the liquid that needs to handle enters in the filtering tank from the following mouth of a river, and liquid from bottom to top flows through fibre bundle, and at this moment suspension is tackled by fiber in the liquid, behind the fluid purification, flow out from filling pipe end.

When backwash, start elevating mechanism earlier, lower wall is descended unclamp fibre bundle, backwash liquid flows into the jar from filling pipe end, and backwash liquid washes fibre bundle from top to bottom, and soiling solution is from mouth of a river discharge down, go up the continuous rotating of dish simultaneously, constantly mud on the fibre bundle is got rid of away, finish until cleaning.

Tow material can be crimp filament fiber, carbonization filament fiber or common long filament chemical fibre etc.

Further describe concrete structure of the present utility model below in conjunction with Figure of description.

Accompanying drawing is one of enforcement structure of the present utility model.

Accompanying drawing number is: coil 6 on elevating mechanism 1, lifting shaft 2, lower cover 3, multifibre 4, Tong body 5, the porous, loam cake 7, go up seal box 8, support 9, rotating shaft 10, rotating mechanism 11, union joint 12, filling pipe end 13, upper flange 14, porous lower wall 15, lower seal box 16, the mouth of a river 17, following 18, base plate 19 down.

With reference to accompanying drawing, make jar by loam cake 7, Tong body 5, upper flange 14, lower cover 3, and seat is on following 18 and base plate 19.Jar becomes vertically device.Filling pipe end 13 is arranged on the loam cake 7, the following mouth of a river 17 is arranged on the lower cover 3, rotating mechanism 11 is fixed on the loam cake 7 by support 9.Rotating mechanism 11 can forward and reversely rotate, and connect with rotating shaft 10 by shaft coupling 12, rotating shaft 10 stretches in the jar by last seal box 8, top and one are equipped with on the porous of multifibre 4 dish 6 and are linked and form integral body, multifibre 4 upper ends are fixed on the porous and coil on 6, and the lower end is a free state.The lower wall 15 of porous is installed in jar, lower wall and lifting shaft 2(the utility model adopt screw rod, also can adopt hydraulic structure) connect, lifting shaft 2 is by being installed in the rubber parts that is sealed into that lower seal box 16(the utility model on the lower cover 3 adopts) stretch out outside the jar, link with the elevating mechanism 1 that is contained on the base plate 19.

When filtering operating mode, start elevating mechanism 1, promote lifting shaft 2 and lower wall 15 risings, when compression multifibre 4 arrives certain compression ratio, stop lower wall 15 and rise, and liquid stream is flowed in the jar from the following mouth of a river 17, the filtering layer that multifibre 4 by being subjected to certain compression ratio forms, filter, filter back liquid is discharged from filling pipe end 13, and liquid is cleaned.When backwash, start elevating mechanism 1 earlier, lower wall 15 is descended, unclamp multifibre 4 and make it into free state, start rotating mechanism 11 this moment, makes dish 6 with forward, reverse continuous change direction of rotation, gets rid of except that the foul on the multifibre 4, and foul is washed away, and discharge from the mouth of a river 17 down by the liquid that enters from filling pipe end 13 stream.Dish 6 rotates on can stopping in backwash, starts elevating mechanism 1, and compression extruding multifibre 4 squeezes addle in the fibre bundle only, restarts elevating mechanism 1 compression multifibre 4 and make it to recover the filtration state after backwash is intact.

The utility model has the advantages that:

1, filtering accuracy is high and stable, measures the filter delivery turbidity with the transmissometer that the secondary distilled water is demarcated zero point, and generally about zero turbidity, the contained suspension particle diameter of water outlet is below 1.5 μ m.

2, backwash is rapidly thorough. Owing to increased the rotation fibre bundle in backwash, the action of extrusion fiber bundle makes rapidly thorough and water-saving of backwash.

3, do not exist the sand core to pollute the filtrate problem.

4, structurally solved the fibre bundle problem of scattering.
