Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of tangential back-flushing filter.
Background technology
Filter is indispensable a kind of device on pumped (conveying) medium pipeline, is conventionally arranged on the entrance point equipment of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment.When fluid enters after the filter cylinder that is equipped with certain specification filter screen, its impurity is blocked, and clean filtrate is discharged by filter outlet, when needs clean, as long as dismountable filter cylinder is taken out, after processing, reloads, and therefore, working service is very convenient.
Filter is widely used in metallurgy, chemical industry, oil, papermaking, medicine, food, mining, electric power, city water field, such as filtration, the regeneration of emulsion, the waste oil filtration treatment of industrial wastewater, recirculated water, the continuous casting water system of metallurgy industry, blast furnace water system, hot rolling high-pressure water descaling system is a kind of advanced, efficient and easy-operating automatic filtering apparatus.
With filter medium, container is divided into upper and lower chamber and forms simple filter.Suspension adds epicoele, and by filter medium, entering cavity of resorption under pressure becomes filtrate, and solid particle is trapped within filter medium surface and forms filter residue (or claiming filter cake).The filter cake layer that in filter process, accumulate on filter medium surface is thickeied gradually, and liquid increases by the resistance of filter cake layer thereupon, and the rate of filtration reduces.When filter chamber is full of filter residue or the rate of filtration too hour, stop filtering, remove filter residue, make filter medium regeneration, to complete filtration cycle one time.
Filter has the filter disc filtering technique of special construction, and performance is accurately sensitive, guarantees that the particle that only has particle diameter to be less than requirement just can enter system, it is the most effective filtration system, inner filter element is firm, nothing is worn and torn, corrosion-free, few fouling, long service life, and regular maintenance is simple, convenient.
Existing filter, when filtration contains the more liquid of impurity, the as easy as rolling off a log obstruction of filter screen, the recoil water yield that removing filter residue needs is more, and the cleaning effect of recoil does not reach maximum standard, have the filter residue that is partly difficult to remove and continue to stay on filter screen, reduce the rate of filtration.
Utility model content
For overcoming the deficiencies in the prior art, the utility model provides a kind of simple in structure, convenient and practical tangential back-flushing filter, and this filter is provided with the recoil tube of tangential access, and during recoil, filter interior has gyrate current, repercussion effect is good, and water consumption is few.
A kind of tangential back-flushing filter, comprise the housing and the upper cover that match, also comprise support, described housing middle part is hinged on support, housing bottom is provided with the recoil tube of tangential access inner walls, and is furnished with magnetic separation filter course and filter screen from top to bottom in described housing.
In the utility model, in filter, be furnished with two-layer filter, be respectively magnetic separation filter course and filter screen, magnetic separation filter course is for removing the magnetic metal impurity of liquid, and filter screen is for filtering the granule foreign of certain specification; And housing middle part is hinged on support, and whole filter can be overturn, by after filter upset, upper cover is positioned at the bottom of housing, and to the recoil slagging-off better effects if of magnetic separation filter course and filter screen, back-flushing is discharged by bottom under Action of Gravity Field simultaneously; Meanwhile, because recoil tube tangentially accesses inner walls, back-flushing has gyrate current in filter, has better repercussion effect, more easily removes the impurity on magnetic separation filter course and filter screen.
As preferably, described support comprises the support bar that is arranged in housing both sides, and housing middle part is hinged on the top of support bar.
As another improvement of the present utility model, the application's filter and plain filter difference are, common filter is erect by feet, and the application's filter housings is hinged on support bar, make housing there is the function of upset, this function, when filter recoils, has better repercussion effect, and the impurity that makes to recoil is removed cleaner.
As preferably, between described housing side and corresponding support bar, be connected with hook.
As further preferred, the base of movable pulley bottom also comprising, described support is housed, and described support bar is arranged on base.
When filter is worked, hook is for the position of stationary housing, and restriction housing overturns; With the base of movable pulley, be convenient to the transfer of filter, make its position put and install more flexible, in moving process, hook can also limit rocking of filter, keeps its balance and stable.
As preferably, described magnetic separation filter course and the tapered layout of filter screen.
The contact area of filter and liquid is larger, and the rate of filtration is faster, and therefore, all tapered layouts of magnetic separation filter course of the present utility model and filter screen, to increase filter area, accelerate the rate of filtration.
As preferably, described magnetic separation filter course is by being the annular rib of layered distribution and being connected with each layer of annular rib and the radial ribs that distributes radially forms, and described annular rib and radial ribs all have magnetic.
Magnetic separation filter course is under the effect of self magnetic force, magnetic impurity in energy adsorptive liquid, reach the object of removing magnetic impurity in filtrate, magnetic separation filter course in the application is comprised of the magnetic annular rib of tool and radial ribs, the time of filtration that two kinds of ribs surround is larger, the rate of filtration is fast, and the magnetic impurity of absorption is difficult for stopping up time of filtration.
As preferably, described inner walls is provided with the support member with groove, and the annular rib that is positioned at the magnetic separation filter course bottom is placed on described groove, and the top of described support member is also provided with the Elastic buckle of fixing described annular rib.
Between magnetisable material and magnetic separation filter course, have absorption affinity, recoil is removed and is not often reached good effect, and magnetic separation filter course is fixed by the support member and the Elastic buckle that match, facilitates its installation and removal, is beneficial to the magnetic impurity of removing its absorption.
The utility model is simple in structure, reasonable in design, practical; Tangential recoil tube has better recoil cleaning performance, and the housing of upset is more conducive to the discharge of back-flushing, the magnetic separation filter course of setting, the magnetic impurity in can filtering filtrate.
