Description

A kind of full-automatic water filter

Technical field

The utility model relates to a kind of full-automatic water filter, especially for the water filter of power station technical water supply, belongs to filter plant technical field.

Background technology

The main task of hydroelectric power plant's technical water supply provides the clean cooling water pressure that has to positions such as generator unit stator, generator pilot bearing, turbine-generator units guide bearings, hydroelectric power plant's technology use water is general uses water homology with generating, be river, river is entered by entrance, first thick foreign material are removed through drain grating, all the other dirt impurity are removed again, the water comparatively cleaned through water purifier filtration.In water purifier filtration process, filter screen builds up the foul in water, impurity, form impurity layer, plug filter screen, in filter screen, outer both sides just define a pressure reduction, reduce the filter capacity of water filter, even affect the operation of water filter equipment, now must clean it, except manual cleaning, mostly is adopt back-flushing automatically to clean, but because impurities in water has a large amount of soft materials, such as cloth, plastic tape, pasture and water etc., these impurity can be wound around, extension is attached on filter mesh, only they effectively cannot be removed by high pressure back-flushing, after a period of time, also must shut down by manually removing, not only increase and safeguard intensity, the continuity also affecting equipment is run., all there is the defect that cannot realize completely automatically removing dirt impurity in a large amount of water filter used at present.

Utility model content

The purpose of this utility model is just to provide a kind of full-automatic water filter, and it can thoroughly remove dirt impurity, does not need artificial removing completely.

For achieving the above object, the technical solution adopted in the utility model is: a kind of full-automatic water filter, by electrically operated valve, housing, screen tube, laminate forms, electrically operated valve is positioned at above housing and connects through main shaft the screen tube being positioned at enclosure interior, enclosure interior space is provided with laminate, shell inner surface is provided with two baffle plates, multiple dividing plate is provided with in screen tube, baffle plate, dividing plate, enclosure interior compartition is become filter chamber and blowdown room by laminate, housing has the water inlet being positioned at bottom, superposed delivery port, the superposed recoil mouth of a river, be positioned at the sewage draining exit of bottom, water inlet is communicated with delivery port through filter chamber, the recoil mouth of a river is communicated with sewage draining exit through blowdown room.

Adopt such technical scheme, water is introduced by water filter lower water inlet, enter the filter chamber in water filter, through the filter screen filtration of screen tube, sent by water filter top delivery port, being filtered foreign material that net stops is blocked between the capacitor that the multiple dividing plates in screen tube are formed, along with electrically operated valve drives screen tube to rotate, multiple dividing plate proceeds to blowdown room successively, because the space of capacitor is very little, when screen tube when rotated, the dividing plate of screen tube and laminate form a strong shear cutting edge, larger foreign material can be shredded into less segment foreign material, can will be wound around, hang the foreign material be attached on filter mesh to strike off, foreign material left in mesh just can have been rinsed out by back-flushing easily, like this, shutdown is not needed to carry out artificial removal of contamination completely, just can realize full-automatic thoroughly removing dirt impurity, ensure that the continuity of equipment is run.

Accompanying drawing explanation

Fig. 1 is the front sectional view of a kind of full-automatic water filter of the utility model;

Fig. 2 is the sectional view of Fig. 1 along A-A line.

In accompanying drawing:

1 electrically operated valve; 2 housings; 3 screen tubes; 4 dividing plates;

5 baffle plates; The 6 recoil mouths of a river; 7 laminates; 8 water inlets;

9 blowdown rooms; 10 filter chambers; 11 delivery ports; 12 sewage draining exits.

Detailed description of the invention

Below in conjunction with specific embodiment, a kind of full-automatic water filter of the utility model is further described in detail.

Fig. 1 to Fig. 2 gives the specific embodiment of a kind of full-automatic water filter of the utility model, it is by electrically operated valve 1, housing 2, screen tube 3, laminate 7 forms, electrically operated valve 1 is positioned at above housing 2 and connects through main shaft the screen tube 3 being positioned at housing 2 inside, the cylindrical tube of screen tube 3 has filter bores and form screen pack, multiple dividing plate 4 is provided with in screen tube 3, the quantity of dividing plate 4 can be 4 ~ 40, the present embodiment adopts 16, the length of dividing plate 4 is along screen tube 3 axial distribution, the height of dividing plate 4 is less, general needs 0.5 ~ 25 centimetre, the present embodiment adopts 2 centimetres, multiple like this dividing plate 4 forms capacitor with the screen pack of screen tube 3, housing 2 inner space is provided with laminate 7 and structure shrouding, and laminate 7 lower end extends and connects blow-off pipe, and housing 2 inner surface is provided with two baffle plates 5, and the length of baffle plate 5 is along housing 2 inwall axial distribution and be not less than the height of laminate 7, the inner space of housing 2 is divided into filter chamber 10 and blowdown room 9 by the structure shrouding in baffle plate 5, dividing plate 4, laminate 7 and housing 2, and the distance between dividing plate 4 and laminate 7 is very little, is generally less than 3 centimetres, and the present embodiment adopts 0.5 centimetre, housing 2 has be positioned at bottom water inlet 8, superposed delivery port 11, the superposed recoil mouth of a river 6, be positioned at the sewage draining exit 12 of bottom, water inlet 8 is communicated with delivery port 11 through filter chamber 10, and the recoil mouth of a river 6 is communicated with sewage draining exit 12 through blowdown room 9.

During work, water with dirt impurity introduces filter chamber 10 by water inlet 8, filter through screen tube 3, clean water is drawn by delivery port 11, and dirt impurity is blocked in the capacitor that dividing plate 4 and screen tube 3 formed, and electrically operated valve 1 drives screen tube 3 to rotate, capacitor proceeds to blowdown room 9 successively, dirt impurity falls into blow-off pipe and rotates through screen tube 3 and discharge through dirty mouth 12, if desired, can introduce back-flushing carry out flushing and be beneficial to blowdown by the recoil mouth of a river 6.When electrically operated valve 1 drives screen tube 3 to rotate; dividing plate 4 and laminate 7 form a strong shear cutting edge; larger foreign material can be shredded into less segment foreign material; winding, the extension foreign material be attached on filter mesh can be struck off; foreign material left in mesh just can have been rinsed out by back-flushing easily, like this, do not need shutdown to carry out artificial removal of contamination completely; just can realize full-automatic thoroughly removing dirt impurity, ensure that the continuity of equipment is run.

The foregoing is only preferred embodiment of the present utility model; restriction not to the utility model protection domain; those skilled in the art is not departing from the spirit and scope of the present utility model that claims limit; in the form and details to the many variations that the utility model is made, all fall into protection domain of the present utility model.
