Description
Technical field
This utility model is related to filter for installation field, specially a kind of mistake for centrifugal pump inlet pipeline automatic pollution discharge
Filter.
Background technology
At present, it is domestic to irrigate, drawn water using centrifugal pump more than draining, but the solid particle in water and algae affect pump
Interior blade runs well, and causes the breakage of blade and impeller stuck, shortens the service life of pump, is the liquid that this enters to pumping
Body carries out soil pick-up formula, the brush for filtering particularly significant, generally being adopted（Scrape）Formula and pivoted arm self-cleaning net type filter exist compared with
Big defect, i.e., easily stockpile filtering residue.Meanwhile, if filtering contain in granule hard solid particle, it is easy to wear out filter
Net, operation is inconvenient.
For this purpose, the applicant proposes a kind of filter of achievable automatic pollution discharge, the filter can be used for centrifugal pump inlet
Pipeline so that such type filter does not need any auxiliary flushing pollution discharge device, and its feature is：Small volume, simple structure, into
This is low, and strainability is good, and intensity is high, prevents granule from breaking through filter screen, is easy to repetitive operation.
Utility model content
The purpose of this utility model is to provide a kind of filter for centrifugal pump inlet pipeline automatic pollution discharge, to solve
The problem proposed in above-mentioned background technology.
In order to solve above-mentioned technical problem, the utility model proposes technical scheme below：One kind is used for centrifugal pump inlet pipe
The filter of road automatic pollution discharge, it includes cabinet, and the left side edge of opening of the cabinet is provided with floor by L-type clamping plate, institute
The left side that L-type clamping plate is fixed on cabinet by fixing screws is stated, the other end of the floor is embedded in the draw-in groove of cabinet inside
On, filter outlet is provided with the top of the cabinet, the edge of the filter outlet is provided with flanged plate, the flanged plate
On be machined with uniform manhole, the inside of the cabinet is provided with filtering residue discharge pipe, and the bottom of the filtering residue discharge pipe connects
Elastic link is connected to, the end of the elastic link is provided with filtering residue dump valve.
The floor has 10 groups, and the angle between two adjacent groups floor is 60 degree, the other end and cabinet of the floor
Internal U-shaped card slot is fixedly linked, and the cabinet is integrated casting with U-shaped card slot.
The elastic link material be rubber, its a diameter of 40mm.
The filtering residue discharge valve surface is smooth and angle of inclination is 30 degree.
The long side of the L-type clamping plate is 30mm, and minor face is 18mm.
This utility model has the advantages that：
In system operation, water enters impact on the floor into 60 angles by filter inlet, and solid particle is rushed
Hit after floor, water is entered in cabinet by gap between two dividing plates, for be attached to the solid particle on top in floor from
Under body action of gravity, floor tail end is slipped to, is constantly washed into filtering residue discharge pipe, and for the solid of attachment floor tail end
Grain is directly washed away into filtering residue discharge pipe, and filtering residue dump valve couples with elastic link, because elastic link natural resiliency causes filtering residue
Dump valve is brought into close contact, because impurity is constantly deposited in filtering residue dump valve so that because filtering residue dump valve both sides form larger pressure
Power is poor, and when filtering residue gravity is more than elastic link, filtering residue dump valve is opened, because filtering residue discharge valve surface is smooth and inclines, impurity
Slide and discharge, pressure reduction is reduced, filtering residue dump valve is closed, and realizes the automatic pollution discharge of filter itself.Filter outlet is by circle
Through hole is connected with centrifugal pump inlet pipeline.
Description of the drawings
With reference to the accompanying drawings and examples the utility model is described in further detail.
Fig. 1 is the main cut-away view of this utility model.
Fig. 2 is this utility model top view.
Fig. 3 is the sectional view of filter floor of the present utility model.
In figure：L-shaped clamping plate 1；Floor 2；Filter inlet 3；Fixing screws 4；Cabinet 5；Manhole 6；Filter outlet

Specific embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Such as Fig. 1-3, a kind of filter for centrifugal pump inlet pipeline automatic pollution discharge, it includes cabinet 5, the cabinet 5
Left side edge of opening floor 2 is provided with by L-type clamping plate 1, the L-type clamping plate 1 is fixed on cabinet 5 by fixing screws 4
Left side, the other end of the floor 2 is embedded on the draw-in groove inside cabinet 5, and the top of the cabinet 5 is provided with filter and goes out
Mouth 7, the edge of the filter outlet 7 is provided with flanged plate, and uniform manhole 6 is machined with the flanged plate, described
The inside of cabinet 5 is provided with filtering residue discharge pipe 8, and the bottom of the filtering residue discharge pipe 8 is connected with elastic link 9, and the elasticity is even
The end of bar 9 is provided with filtering residue dump valve 10.
Further, the floor 2 has 10 groups, and the angle between two adjacent groups floor 2 is 60 degree, the floor 2
The other end is fixedly linked with the U-shaped card slot inside cabinet 5, and the cabinet 5 is integrated casting with U-shaped card slot.
Further, the material of the elastic link 9 be rubber, its a diameter of 40mm.Other materials are rustless steel.Due to
