A kind of efficient magnetic filter
Technical field
The utility model is related to sewage treatment fields, and in particular to a kind of efficient magnetic filter.
Background technology
Filtering, there are many mode of the process for being purified fluid purification by special device, filtering, and the object system used is also very wide
General, solid-liquid, solid-gas, bulky grain, little particle are typical.
Filtering is the liquid in motive force or other outer force effect low suspension liquid (or the gas that generates heat containing solid particle)
(or gas) penetrates medium, and solid particle and other substances are retained by filter medium, to make solid and other substances and liquid
The operation of (or gas) separation.
Make liquid consolidate or gas-solid mixture in fluid be forced through porous filter medium, by suspended solid particles therein
It is retained, is a kind of unit operation belonging to fluid dynamical process to realize the separation of mixture.The mistake of liquid-solid mixture
Filter is in pressure difference(Including pressure difference caused by gravity)Or it is carried out under centrifugation force effect.Mixture to be filtered is known as filter pulp, passes through
The supernatant liquid of filter medium is known as filtrate, and the solid particle layer being trapped is known as filter cake.The filtering of gas-solid mixture is generally being pressed
Difference effect is lower to be carried out.The purpose of filter operation is sometimes to obtain clear fluid, such as the filtering of lubricating oil or air;Sometimes
For the solid particle to be suspended, crystal product is detached from mother liquor when such as crystallizing;Sometimes then the two has concurrently.
Filter method can be divided into according to the motive force of process, filtering:1. gravity filtration, operation motive force is suspension itself
Fluid column static pressure, be usually no more than 50kPa, this method is only applicable to that processing grain graininess is big, poor filter pulp;2. pressurizeing
Filter pulp is pressurizeed with pump or other modes, can generate higher operating pressure by filter, general up to 500kPa or more, can effectively be located
The filter pulp of the difficult separation of reason;3. vacuum filter is vacuumized in filter medium bottom side, generated pressure difference is typically not greater than 85kPa,
Suitable for the filter pulp containing ore particle or crystal grain, and convenient for washing filter cake;4. centrifugal filtration, operating pressure is that filter pulp layer generates
Centrifugal force, convenient for washing filter cake, the liquid content of gained filter cake is few, be suitable for crystal material and fibre material filtering.Filtering
There are many type of equipment.Usually claim the machine for implementing gravity filtration, pressure filtration and vacuum filter to filter;It will implement to centrifuge
The machine of filtering claims filter centrifugal.
Magnetic filter mainly to form magnetic wadding walk by being combined the magnetic impurity in water quality with magnetic powder, eventually by
Magnetic sheet absorbs and filter, to achieve the purpose that water filtration.This existing magnetic filter filter effect is bad, meanwhile, it is general to be discharged
Mouth is set to top, is unfavorable for bottom water quality discharge, and magnetic powder collects the problems such as inconvenient.
Utility model content
The purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of efficient magnetic filter.
In order to solve the above technical problems, the technical solution of the utility model is:
A kind of efficient magnetic filter, including lauter tub, two magnetic sheets, wadding mud collecting tank, two cowling panels, water inlet, go out
The mouth of a river, backwash mouth, filter plate;The water inlet is set at the top of the lauter tub, and the water outlet is set to the lauter tub bottom, institute
It states backwash mouth and is set to both sides above the lauter tub, two are equipped in the lauter tub between the backwash mouth and the water inlet
A cowling panel, the magnetic sheet, which tilts, to be set on the lauter tub inner wall below the backwash mouth, two magnetic sheets it
Between be equipped with the wadding mud collecting tank;It is laterally fixed on the lauter tub inner wall between the wadding mud collecting tank and the water outlet
The filter plate;
Specifically, being equipped with sliding slot close to one end of the wadding mud collecting tank on the magnetic sheet, leaned on the wadding mud collecting tank
One end of the nearly magnetic sheet is equipped with sliding block corresponding with the sliding slot, and the sliding block is movably arranged in the sliding slot.
Further, the backwash mouth shaft centre line extended line is parallel with the magnetic sheet.
Further, angle β is formed between two cowling panels, and the angle β sizes are 115-125 °.
Further, the magnetic sheet forms angle α with the lauter tub inner wall, and the angle α size is 55-65 °.
The beneficial effects of the utility model are:(1)Wad a quilt with cotton opposite can slide dismounting between mud collecting tank and magnetic sheet, facilitate
Magnetic powder collects and recycles, and environmental protection and has saved cost;(2)Water outlet is located at lower section in the device, convenient for the water after Magnetic filter
Discharge;(3)The device magnetic sheet adsorption effect is good, and good filtration effect can be widely used in the filtering of water quality in multiple fields.
Description of the drawings
It is attached that FIG. 1 is a schematic structural view of the utility model;
Attached drawing 2 is A enlarged structure schematic diagrams in attached drawing 1;
Attached drawing 3 is magnetic sheet and wadding mud collecting tank side view status architecture schematic diagram.
Specific implementation mode
To make the structure feature to the utility model and the effect of being reached has a better understanding and awareness, to compared with
Good embodiment and attached drawing cooperation detailed description, are described as follows:
As shown in Fig. 1, a kind of efficient magnetic filter, including lauter tub, two magnetic sheets, wadding mud collecting tank, two rectifications
Plate, water inlet, water outlet, backwash mouth, filter plate;The water inlet is set at the top of the lauter tub, and the water outlet is set to institute
Lauter tub bottom is stated, the water outlet is located at lower section, convenient for the water discharge after Magnetic filter.The backwash mouth is set on the lauter tub
Square both sides are set there are two the cowling panel in the lauter tub between the backwash mouth and the water inlet, from the water inlet
The water that mouth enters first passes around the cowling panel and is shunted to both sides, and angle β, and the angle are formed between two cowling panels
β sizes are 115-125 °, and in the present embodiment, the angle β is most preferably sized to 120 °, and such design can be protected effectively
