Abstract

The utility model relates to a fluidised filter for filtering the solid particles in the liquid, comprising a skeleton which is composed of firmly connected components including a cylinder, inner screwes, a circle, a strip or a plate and a cone, etc. The skeleton is coated by a cylindrical sieve to form a circular drum sieve; the skeleton is coated by a cone sieve to form a cone drum sieve. The sieve is horizontally installed in the supporting frame which is provided with a supporting base with rollers. The spiral fluidization is formed by filtering the fluid, which adopts the power to drive the rotation. The gradient concentration is established and the special sieve smoothes the filtering surface. The fluidised filter has tensile and compressive features. The fluid discharges from the sieve hole. The filter residue discharges from the discharge port of the little cylinder. The utility model has the advantages of simple structure, low cost, convenient operation and wide purpose.

Description

Fluidised filter

The utility model belongs to a kind of fluidization filter plant, is used for filtering the solid particle of fluid.

Filter press in the past, filter plant such as centrifugal separator, double cylinder vertical solution filter is generally all heavier, required metal material is many, Microfilter, solid-liquid separating machine filter plants such as (are efficient solid-liquid separating machine as poly-precious board CYL) not only weigh, required metal material is many, and exist screen cloth easily to break, defectives such as installation and maintenance inconvenience.Also there is the defective that can not satisfy big flow filtering flow in above-mentioned various filter plant.Filter plants such as grid, water pouring sieve can not be removed filter residue automatically; Though filter plant such as filter screen, Microfilter can be removed the filter residue of crossing on the filter screen automatically, handles the structure more complicated, and the defective that reduces work efficiency is arranged.

The purpose of this utility model provides a kind of light, and is simple in structure, and screen cloth is durable in use, and is easy to install, dismantle, and can slag tap automatically, can satisfy the fluidization filter plant of big flow filtering flow, to satisfy the filtration requirement of various different fluid.

The purpose of this utility model realizes by following scheme: with an end be charging aperture little cylinder and with the cone of its binding, great circle, the other end is the little cylinder that has internal thread of discharging opening and the cone of being made up of conical internal thread that links together and taper screen cloth, the great circle cylindrical shell of forming by internal thread and cylindrical screen in the middle of the great circle, and run through by internal thread and to be connected and fixed the helicon circular drum sieve that is combined into and to crouch and be contained in the support that is provided with roller support, power drives helicon circular drum sieve and rotates, filter fluid and after roundlet cylindrical shell charging aperture flows into the great circle cylindrical shell, advance the fluidization of formation spiral with internal thread, filter fluid and discharge, cross filter residue and discharge from the roundlet barrel discharge hole by sieve screen apertures.

The embodiment that provides below in conjunction with accompanying drawing further introduces content of the present utility model.

Fig. 3 is the utility model fluidization filter left view.

As shown in drawings, helicon circular drum sieve ［ 1 ］ is by not tapped little cylinder ［ 3 ］, cone ［ 12 ］, the band internal thread ［ 5 ］ little cylinder ［ 2 ］ and by conical internal thread ［ 6 ］, conical screen cloth ［ 7 ］, great circle ［ 4 ］, internal thread ［ 5 ］, cylindrical screen parts such as ［ 8 ］ are formed, wherein not tapped little cylinder ［ 3 ］ is for filtering fluid feed mouth ［ 3 ］, the little cylinder ［ 2 ］ that has internal thread was the filter residue discharging opening, internal thread ［ 5 ］, ［ 6 ］, great circle ［ 4 ］, little cylinder ［ 2 ］, ［ 3 ］, cone parts such as ［ 12 ］ are made with metal or other high-strength materials, its junction can be with welding or riveted and fixed, roundlet cylindrical shell internal thread ［ 5 ］ and conical internal thread ［ 6 ］, great circle cylindrical shell internal thread ［ 5 ］ hand of spiral unanimity, the spiral shell square is even, there are several bands or plate ［ 13 ］ evenly to link internal thread inner edge ［ 14 ］ fixing respectively, the spiral shell square is evenly fixing, and extend from an end of internal thread and to be fixed to the other end, internal thread outside ［ 15 ］ is fixedly connected with great circle ［ 4 ］ and the little cylinder of discharging opening ［ 2 ］, and general employing welding is fixing.Screen cloth ［ 7 ］［ 8 ］ is by two-layer synthetic, and the inner layer screen mesh is tiny to play filtration, and the thick protection inner screen that is mainly used in outer screen hole is to bear pressure and the pulling force that filters fluid, in order to avoid mesh rupture.Screen cloth is made cylindrical shape and taper shape, also cylindrical screen and conical screen cloth can be connected together, be inserted in from the little cylinder of discharging opening ［ 2 ］ during installation, fixing two ends, at the great circle ［ 4 ］ of centre but on also fixed grit, make and filter fluid and can only flow out and can not from other slits, flow out through sieve screen apertures.Helicon circular drum sieve ［ 1 ］ crouches and is contained in the support ［ 9 ］ that is provided with roller support ［ 10 ］, the little cylinder ［ 2 ］ at two ends, ［ 3 ］ be connected with roller support ［ 10 ］, power ［ 11 ］ drives helicon circular drum sieve ［ 1 ］ and rotates, fluid forms the spiral fluidization along the parallel propelling of internal thread ［ 5 ］ in the great circle cylindrical shell, in conical screen cloth ［ 7 ］, advance up along internal thread ［ 6 ］, fluid is not only along the internal thread translation, and the turbulence of in whole sieve nest, rolling, the earlier rare back of solid is dense, cumulative, internal thread ［ 5 ］［ 6 ］ is constantly pushed ahead fluid, and spiral fluidization process is crossed roundlet barrel discharge hole ［ 2 ］, crosses filter residue and discharges.

The fluidization filter is by cylinder, the internal thread body, great circle, bar or plate, parts such as cone firmly binding are combined into skeleton, the outside puts the conical screen cloth of cylindrical shape promptly becomes a kind of helicon circular drum sieve, this sieve crouched be contained in the support that is provided with roller support, promptly become the fluidization filter, this filter is used to filter fluid, promptly form the spiral fluidization, can be widely used in the filtration paper-making industrial waste water, the former water of running water, municipal sewage system water, big flow fluid such as motor-vehicle tail-gas, also can be used for reclaiming brewery, waste residue in the industrial wastewaters such as paper plant obtains high economic benefit.

Good effect of the present utility model and advantage:

One, fluidised filter utilizes the characteristic of solid particle and fluid continuous-flow, solid content rareness, adopts taper screen cloth, great circle cylindrical shell and roundlet cylindrical shell to set up the concentration ladder Degree, special screen cloth manufacturing makes the filtering flow face smoothly without hindrance, and energy tension resistance to compression, make fluid in littler filter area and filter space, obtain bigger filtering traffic, fluid can not only be filtered along the internal thread translation, and the turbulence of rolling in whole sieve nest is filtered, becoming mechanical filter filters into motion, obtain better filter effect, compare with filtering technique in the past, the utility model has outstanding feature and progress.

Two, simple in structure, in light weight, cost of investment is low, uses the economic benefit height.

The fluidization filter does not need special processing and retrofit to make, and a fluidization filter has only about 0.2 ton, will reduce 5 times to 10 times than the filter weight of identical filter capacity, the corresponding minimizing of cost of investment, and the energy self-skimming, the moisture content of slag is lower, and recovering effect is good.

Three, can reduce labor intensity, improve the screen cloth utilization rate, the screen cloth easy installation and removal.

Four, the whole machine installation occupation of land is few, instant effect, and cost is low, penetration and promotion easily.
