Abstract

A multi-functional fiber filter, housing (1) is a cylindrical pressure container; the lower part of the container is a deposit section (flocculation, deposition and concentration areas), the middle part is a transition area and the upper part is filtering area. In filtering area, some filter tubes (3) with length similar to radius were extended downwards along the top of cylinder and the filter tube is connected with outlet pipe (6); non-purified water comes from inlet pipe (2) at the bottom of container, forming deposit from bottom to up and running to filtering area through transition area, after filtering by filter tube (3), a water flow is formed in filter tube (3), which comes out of container through outlet pipe (6) for purpose of purification. It has advantages of finishing flocculation, deposition and concentration and filtering or deposition and concentration at the same time within one container. The structure is simple and the device runs and operates conveniently.

Description

A kind of multifunctional fibre filter

Technical field

The utility model relates to a kind of multifunctional fibre filter, belongs to the chemical process reactor and makes the field.

Background technology

Separation of Solid and Liquid is chemical industry, Eternal Theme of water treatment field all the time.Precipitation, filtration are the most frequently used technology, but majority is precipitation, filters and independently carrying out in the reactor; Some integrated water treatment equipment has designed precipitation and has filtered two processes, but neither carry out in pressure vessel, and the liquid level restriction is arranged, and can not finish three technical process (precipitation is filtered, perhaps precipitate simultaneously and filter).

In recent years, be that the fiber filter technical development of filter medium is rapid with the fiber, various fabric filters (pond) competitively occur.These fabric filters (pond) rate of filtration is fast, and filter cycle is long, regulates fibrage density with removable orifice plate or rubbery human body, is used widely.In use find: regulate fibrage density with removable orifice plate or rubbery human body, can not accomplish to adjust at any time according to water quality requirement; Fibrage density is less than normal, and filtering accuracy is not high; Fiber layer thickness〉1.3 meters, when fibrage stops up, long with the compressed air backwash time; The difficult problem of fibrage expansion still, still existed fibrage density less than normal when the comet type fabric filter had solved backwash, and filtering accuracy is not high, the problem that the backwash time is long.

The utility model content

The purpose of this utility model provides a kind of multifunctional fibre filter, and it can effectively improve filtering accuracy, shortens the backwash time, improves filter efficiency, has the precipitation function simultaneously.

The technical solution of the utility model is achieved in that

The utility model is a kind of multifunctional fibre filter, and shell 1 is a cylindrical pressure vessel, is settling zone (flocculation, precipitation, inspissation district) in the bottom of container, and the middle part is a transition region, and top is filtering area.At filtering area, put in the screen pipe 3 of some length approaching radius downwards along the cylinder top, the outer outlet pipe 6 of screen pipe 3 and container communicates; Raw water is entered by the water inlet pipe 2 of container bottom,, finishes precipitation process earlier from bottom to top, enters filtering area by transition region again, and the well casing structure of horizontal filtering pipe 3 and underground water well is similar, and work principle of filter is the same.Therefore, under pressure, water forms current by screen pipe 3, outside outlet pipe 6 flow containers.Screen pipe is by fixedly skeleton grizzly bar 15, adjusting device 10, fibrage 14, protection fibrage grizzly bar 13, four parts are formed.Fixedly skeleton grizzly bar 15 upper ends tighten together with protection fibrage grizzly bar 13 upper ends, two-layer grizzly bar is along two different circumference disposed at equal distance of size, fixedly skeleton bar 15 passes and regulates disk 12, regulate disk 12 and be positioned at fibrolaminar lower end, fixedly the periphery of skeleton grizzly bar 15 is twined fibrage 14, overlap a circle protection fibrage grizzly bar 13 on fibrage 14 external diameters again and protect fibrage, the restriction fiber; It is fixing that protection fibrage grizzly bar 13 lower ends are welded steel ring 16 in the inner part.During installation, the skeleton periphery all twines full fibrage 14, and fibrage density satisfies the initial stage and filters requirement.Be positioned at perforate on the adjusting disk 12 of fibrage lower end, allow grizzly bar pass, when grizzly bar 15 moved around, fibrage 14 moved and compresses or expand with regulating disk 12 along axis direction, makes its variable density at the rotation downward modulation pitch circle dish 12 of handwheel.Change fibrage density and can adapt to the different turnover water yields and turnover water quality requirement; For example: improve effluent quality, just will regulate disk and move up, then fibre density becomes big, and the space diminishes, and filtering the water yield will reduce, and filtering accuracy improves; Otherwise, reduce effluent quality, just will regulate disk and down extend, then fibre density diminishes, and it is big that the space becomes, and filtering the water yield will increase, and filtering accuracy descends.In a word, at any time by adjusting device 10 enforceable change fibre densities, and guaranteeing filtering water, is that other filter methods are difficult to accomplish, and after density increased, the good of water quality also was that other fabric filters are difficult to accomplish.Improve the water yield and also have a way, improve the pressure in the container exactly, strengthening the inside and outside pressure differential of screen pipe increases the water yield; When finding filtered water quantitative change hour, stop into water, reduce water level in the container, will regulate disk and be elongated to the longest, loosen fiber, reduce fibre density, utilize compressed air to clean earlier, again by the big yield backwash, because fibrous filter layer is very thin, therefore, the backwash time is short especially, and backwash level is more thorough.If only need precipitation process, fibre density can be transferred to minimum, there is not filtration resistance basically, satisfy the burden requirement of precipitation.

The thickness of fibrage 14 is at 10～20mm, initial density≤130kg/m ³Diameter phi＜the 150mm of grizzly bar skeleton.

The utlity model has following beneficial effect:

1. reasonable in design, compact conformation can be finished flocculation, precipitation, concentrate in a container, filter, and perhaps precipitates simultaneously and filters three technical process.If in the time of only need precipitating, can fibre density be put into minimum by regulating disk, make and filter the needs that the water yield satisfies precipitation; Filter if also need, can fibre density be increased by regulating disk 10, guarantee to filter the back water quality requirement, in a word, at any time by adjusting disk 10 enforceable change fibre densities, and guarantee filtering water, be that other filtration sides are difficult to accomplish, and this apparatus structure is simple, operation, easy to operate.

Therefore 2. at filtering area, put in the screen pipe 3 of some length approaching radius downwards along the cylinder top, screen pipe quantity is many, and filter area is big, and it is big to filter the water yield.

3. at any time by regulating disk 10 enforceable change fibre densities, especially after the density increase, the good of water quality also is that other fabric filters are difficult to accomplish.

4. because fibrous filter layer 14 is very thin, therefore, the backwash time is short especially, and backwash level is more thorough.Save the water yield, energy savings is saved time, and improves throughput of filtration.

5. when maintenance, the manhole by sidepiece enters, and is rational in infrastructure, easy to maintenance.
