Description

Filter membrane pressure filter pot

The utility model relates to the particulate matter filter in a kind of sewage and the waste water, is a kind of Filter film type pressure filter.

What solid particle (containing suspension) was adopted in some removal sewage at present is a kind of vertical circular vapor tight tank, common name pressure filter, the interior filtering layer that forms with the filter medium of coal and various sand shapes of airtight tank body.During use, sewage is injected by tank deck, discharges at the bottom of jar through filtering layer, thereby the particle in the sewage is trapped in filtering layer surface and deep.If on the filtering layer to hold back layer blocked up and when influence the filter effect and the rate of filtration, then adopt the method for the water that upwards recoils from the tank body bottom, trapped substance oppositely and is in addition directly gone out.This filter type not only easily stops up, the trouble of fixing a breakdown, filtration poor stability, and the big secondary pollution that also easily causes water of water consumption.

The purpose of this utility model provides the openable Filter film type pressurized tank of a kind of tank body, and not only filter effect is stable for it, be difficult for stopping up, and be convenient to change filter course and handle filtering layer on trapped substance, and can reduce the secondary pollution of water.

The purpose of this utility model is achieved in that this pressure filter still adopts vertical cylindrical can, and the water injection pipe and the drain structure that is located at tank base that are located at the tank body top.Its main feature is: this vertical tank is by upper tank body and this two parts be combined into of lower tank.And be provided with three vertical rails in the vertical tank outside, the top of guide rail is fixed in upper tank body upper rail lower end and is fixed on the sole plate of vertical tank, thereby forms one with the unsettled half tank body of guide rail.And the top in lower tank is the filter course that is made of fabric layer and support bed, and is force transferring structure in the bottom of jar inner filtration layer.Three leading arms of force transferring structure see through the tank skin of lower tank and realize sliding the connection with the guide rail that is located at the tank body outside respectively, and force transferring structure then withstands on the lowering or hoisting gear that is located at the lower tank bottom, and this lowering or hoisting gear is fixed on the sole plate of vertical tank.So just, formed and a kind ofly supported the openable vertical tank that lower tank combines with upper tank body by jacking apparatus.

Narrate embodiment according to accompanying drawing below.

Fig. 1 is the structural representation of Filter film type pressure filter.

Fig. 2 is the structural representation of lower tank.

Fig. 3 is the structural representation of hydraulic pressure or pressure liftable device.

Fig. 4 is the structural representation of manual screw mandrel lowering or hoisting gear.

As shown in Figure 1: this pressure filter also is a kind of vertical cylindrical can, and cylindrical can is by upper tank body 1 and lower tank 2 be combined intos.Be respectively equipped with ring flange 3 and sealing gasket 4 in the junction of last lower tank.The top of upper tank body 1 promptly communicates with sewage ascending pipe 6 through valve 5, communicates with compressed air hose 8 through valve 7 again, and also be provided with Pressure gauge 9 on upper tank body 1.The vertical rail 10 that three equidistant placement are arranged in the outside of vertical tank, the top of every guide rail 10 all are to be fixed on the shell of upper tank body 1 through fixture 11 and 12, and the lower end of guide rail 10 then is fixed on the sole plate 13 of vertical tank.So just, formed with three guide rails 10 upper tank body 1 is fixing and place vacant state, made lower tank 2, just can coincide into the vapor tight tank of an integral body with upper tank body 1 as long as along the guide rail slippage that makes progress.The jar end of lower tank 2, be provided with drainpipe 14, top in the lower tank 2 is filtering layer, filtering layer is to be made of fabric layer 15 and support bed 16, fabric layer 15 can adopt the filter membrane of terylene filter cloth, canvas, nylon filter cloth or similar material as filter medium, and support bed 16 then is a kind of round pallet that has the open-work that gathers.The edge of support bed 16 is stuck on the boss that inwall protruded 17 of lower tank 2.If contain the uneven particulate matter of size in the sewage, can also utilize this structure of filtering layer, also can be provided with 1-3 layer different size screen cloth, every layer of distance that screen cloth is all certain at interval on the top of lower tank filtering layer, and the sieve aperture maximum of the superiors, no matter screen cloth or filtering layer all are arranged in the lower tank 2.So just can make the particulate matter in the sewage carry out layered filtration.Be intensity that keeps lower tank and the anastomose property of going up lower tank, also be provided with force transferring structure at the end in the bottom of support bed 16 and the jar of lower tank 2.

As shown in Figure 2: this force transferring structure is made up of support bar 18, filler ring 19 and three leading arms 20.The lower end of support bar 18 is reducing disks, and wherein roundel is down, and big disk is last, the outside at the bottom of the tank skin that roundel sees through lower tank 2 is exposed at jar, and the inboard at the bottom of big disk then is positioned at jar, the top of support bar is a tubulose.Three leading arm 20 the inners are welded on the caliber of support bar 18, and its leading arm outer end has sliding sleeve 21 and is positioned at the outside of lower tank 2, and sliding sleeve 21 is enclosed within on the guide rail 10.For improving the weight capacity of support bed 16, between support bed 16 and leading arm, fill up a filler ring 19, filler ring 19 is an annular, and the annulus lower end has three five equilibrium grooves, and groove is inlayed respectively and is crouched on three leading arms 20.Leading arm 20 and support bar see through the tank skin place and all weld together with tank skin.Like this, just having formed with the force transferring structure is the skeleton of lower tank, has realized the draw bail that slides up and down of lower tank and guide rail, drives lower tank and slides up and down openable in other words dynamic structure then by lowering or hoisting gear.

Shown in Figure 3 is the lowering or hoisting gear of hydraulic pressure or air pressure, this device mainly is made of hydraulic pressure (or pneumatic) cylinder 22 and lifting pin 23, piston in lifting pin 23 lower ends and the hydraulic cylinder 22 connects together, the upper end of lifting pin then directly heads in the roundel groove of support bar 18 lower ends, and hydraulic cylinder 22 is fixed on the sole plate 13.Like this, be enough to guarantee combining closely of lower tank and upper tank body as long as hydraulic means started to, pressure filter just can be worked.If when the trapped substance in jar need be removed,, open air door 7, and with the lowering or hoisting gear release, just lower tank depends on deadweight to open as long as close sewage valve 5.

Shown in Figure 4 is mechanical lowering or hoisting gear, and it is to make lower tank jack-up by manual screw mandrel.Manual screw mandrel lowering or hoisting gear is to be made of nut seat 24, screw mandrel 25 and the handle 26 that is fixed on the screw mandrel, and the screw mandrel upper end withstands in the roundel groove of support bar 18 lower ends, and nut seat is fixed on the sole plate 13.

The utility model is owing to adopted yarn fabric to do filtering layer and lower tank retractable structure, not only improved the utilization rate of dischargeable capacity in the tank, become easier but also make to remove trapped substance and change filtering layer, have again simultaneously and filter the advantage of stablizing and avoiding the secondary pollution of water.
