Abstract

A solid-liquid separation filtration device for filtering out solid particles in a fluid assemblies a small cylinder, a corn, a big circle, a cylindrical sieve, a sustained pipe, spiral leaves, a conical sieve, conical spiral leaves, a sustained pipe loop and a strengthening loop concentric parts into a spiral cylindrical and conical roller sieve by a middle axis. A gutter provided with a liquid material outlet, a roller support and a roller, together with a rack and a machine cover forms a machine body. The roller sieve is arranged in the wheel of the gutter to a spiral roller filter. As the roller sieve is run with force, the fluid from the material outlet flows into the roller sieve continuously rolls and forms a spiral loose fluidized bed. The solid particles in the fluid accumulate more and more, pushes forward constantly along spiral leaves and discharges through the residue outlet. The liquid filtered by the sieve is discharged through the liquid outlet on the gutter.

Description

Helix drum formula filter

Technical field: the utility model belongs to a kind of Separation of Solid and Liquid filter, is used for filtering the solid particle of fluid.

Background technology: to be used for solid-liquid separation filtration equipment all heavier as centrifugal separator, filter press in the past, required metal material is many, Microfilter, recection type solid-liquid separating machine (as SXF series recection type rotation fine fack) are not only heavy, volume is big, and exist screen cloth easily to stop up and break, defective such as installation and maintenance inconvenience; The defective that also have the structure more complicated, need backwash, work efficiency is low.Also there is the defective that can not satisfy big flow fluid separating and filtering in above-mentioned various filter plant.

The purpose of this utility model provides a kind of simple in structure, and screen cloth is durable in use; And be easy to install, dismantle the energy automatic discharge; Can satisfy the solid-liquid separation filtration equipment of big flow fluid; Can be suitable for the separating and filtering requirement of various different fluid.

Summary of the invention: with an end is the little cylinder and the connected cone of charging aperture; The other end is the spiral circle cone that the little cylinder that has internal helical blades of discharging opening and the cone-type spiral that links together with it, taper screen cloth are formed; Great circle is fixed on stiffening ring, the stay pipe backing ring and stay pipe, helical blade, cylindrical screen are formed the great circle cylindrical shell; By a central shaft these parts fixed combination are become the circular conical trommel of a kind of spiral.The tank and the support that are provided with liquid outlet opening, roller support, roller are formed body, just becoming helix drum formula filter on the circular conical trommel of the spiral roller that is contained in the tank for sleeping in.Power drives on the roller of the circular conical trommel of spiral in tank and rotates, filter fluid and constantly after roundlet cylindrical shell charging aperture flows into the great circle cylindrical shell, advance a kind of fluidized-bed layer of formation with helical blade, the liquid that sieve screen apertures leaches is discharged from the liquid outlet opening on the tank, crosses filter residue and discharges from the roundlet barrel discharge hole that has internal helical blades.

Description of drawings: Fig. 1 is a helix drum formula filter front view, and Fig. 2 is a helix drum formula filter left view.

As accompanying drawing 1, shown in Figure 2, the circular conical trommel of spiral [3] is by not forming with little cylinder [16], stay pipe backing ring [19], the stiffening ring parts such as [20] of the little cylinder [4] of helical blade, cone [5], great circle [6], cylindrical screen [7] [9], stay pipe [10], helical blade [11], axis, [12], conical screen cloth [14], cone spiral vane [15], band internal helical blades.Wherein not with the little cylinder [4] of helical blade for filtering the fluid feed mouth, the little cylinder [16] that has internal helical blades was the filter residue discharging opening.Little cylinder [4] [16], cone [5], great circle [6], stay pipe [10], helical blade [11], cone spiral vane [15], stay pipe backing ring [19], stiffening ring [20] parts can be used welding or bolting with metal material and concentric being made of axis [12], its junction.Helical blade [11], cone spiral vane [15] pitch are evenly, direction as one man is fixed on the stay pipe [10].Screen cloth is two-layer synthetic by outer screen cloth [7], interior screen cloth [9], the tiny filtration of inner layer screen mesh, 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 inner screen is broken.Screen cloth is made cylindrical shape and taper shape, cylindrical screen [7] [9], conical screen cloth [14] are installed on the fixed port of great circle [6] and little cylinder [16], and make screen cloth be close to the exterior rim of helical blade [11], cone spiral vane [15], the filtration fluid can only and can not be flowed out from other slits through the sieve screen apertures filtration.The circular conical trommel of spiral [3] crouches and is contained on the interior roller that is provided with roller support [22] [21] of tank [8], and tank [8] is fixed on the support [2].The circular conical trommel of spiral [3] drives power transmission shaft [18] by power and is transmitted to minor sprocket [23] by speed governing decelerator [17] and drives the hinge wheel [13] that is fixed on the great circle [6] and go up rotation at roller [21].

The specific embodiment:

1, helix drum formula filter can be widely used in big flow filtering flow such as urban garbage disposal and industrial wastewater, city domestic sewage, the former water of running water and carries out preliminary treatment.When being used for reclaiming the waste residue of industrial wastewaters such as paper mill, brewery, can obtain high economic benefit.

2, helix drum formula filter utilizes the characteristic of solid particle continuous-flow in fluid, solid content rareness, adopt great circle cylindrical shell, taper screen cloth, roundlet cylindrical shell to set up concentration gradient, the measuring body screen making of tension makes fluid without hindrance in the smooth filter of filtering surface, the fluid panting of rolling in whole screen drum again when the helical blade translation is filtered in rotary screen is filtered, become mechanical filter and filter, thereby fluid obtains bigger filtering traffic and splendid filter effect in less filter area and filter space into motion.It is interior along the parallel propelling of helical blade that fluid enters the circular conical trommel of spiral continually, and the panting of rolling in whole cylinder sieve nest forms a kind of spiral particulate fluidization bed; The solids that contains in the fluid is dense, cumulative by earlier rare back behind the interior screen filtration, and constantly pushes ahead along helical blade, advances up along cone spiral vane, discharges until the roundlet barrel discharge hole; The liquid that screen cloth leaches is discharged by the liquid outlet opening on the tank.

3, helix drum formula filtering machine structure is simple, and is in light weight, do not need special material and retrofit to make.Its special structure design technology can automatic discharge, and screen cloth is convenient for installation and maintenance.
