Description

A kind of back flushing pipeline strainer
Technical field
A kind of back flushing pipeline of the utility model strainer belongs to the line strainer technical field.
Background technology
Strainer is indispensable a kind of device on the delivery medium pipeline, is installed in the entrance end of reducing valve, pressure release valve, Valve for keeping constant water level or miscellaneous equipment usually, is used for eliminating the impurity in the medium, with the normal use of protection valve and equipment.After the fluid entering was equipped with the filter cylinder of certain specification filter screen, its impurity was stopped that the filtrating of cleaning is then discharged by filter outlet; When needs clean, dismountable filter cylinder is taken out, reload after the processing and get final product; But need the periodic cleaning strainer; In order to avoid the impurity that filters out is too much or stop up filtering net, shorten its work-ing life, operation inconvenience.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of strong detergency, convenient economic back flushing pipeline strainer.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of back flushing pipeline strainer comprises loam cake, urceolus and filtering net; Loam cake is connected through screw thread with urceolus; The inner below of urceolus is provided with many pillars, and the pillar top is equipped with filtering net, and filtering net is connected through screw thread with loam cake; Cover on described and be provided with former water prosopore and clear water posticum; An outlet of former water prosopore is located at the outside of loam cake, and the passage that filtering net and urceolus form is led in the bottom that another outlet of former water prosopore is located at loam cake, is filled with poly-phosphate in the passage of described urceolus and filtering net; An outlet of clear water posticum is located at the top of loam cake; The inside of filtering net is led in the bottom that another outlet of clear water posticum is located at loam cake, and described outer tube bottom is provided with sewage outlet, and sewage outlet is through the valve that has been threaded.
Described filtering net is an environment-friendly PE polyester mesh filter core.
Described poly-phosphate is a food grade import poly-phosphate.
The utility model compared with prior art has following beneficial effect.
1, the utility model is provided with sewage outlet, only needs during periodic cleaning valve open just can be washed away the impurity in the strainer, flows out sewage outlet, and filtering net is difficult for blocked, has increased the work-ing life of filtering net, the not only simple and efficient cost that also reduced.
2, the utility model adopts food grade import poly-phosphate, can suppress the crystalline generation effectively and repair the erosive metallic conduit, has increased the work-ing life of strainer.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 is loam cake, and 2 is urceolus, and 3 is filtering net, and 4 is former water prosopore, and 5 is the clear water posticum, and 6 is pillar, and 7 is poly-phosphate, and 8 is sewage outlet, and 9 is valve, and 10 is passage.
Embodiment
A kind of back flushing pipeline strainer as shown in Figure 1; Comprise loam cake 1, urceolus 2 and filtering net 3, loam cake 1 and urceolus 2 are connected through screw thread, and urceolus 2 inner belows are provided with many pillars 6; Pillar 6 tops are equipped with filtering net 3; Filtering net 3 and loam cake 1 are connected through screw thread, and described loam cake 1 is provided with former water prosopore 4 and clear water posticum 5, and an outlet of former water prosopore 4 is located at the outside of loam cake 1; The path 10 that filtering net 3 and urceolus 2 form is led in the bottom that another outlet of former water prosopore 4 is located at loam cake 1; Be filled with poly-phosphate 7 in the path 10 of described urceolus 2 and filtering net 3, an outlet of clear water posticum 5 is located at the top of loam cake 1, and the inside of filtering net 3 is led in the bottom that another outlet of clear water posticum 5 is located at loam cake 1; Described urceolus 2 bottoms are provided with sewage outlet 8, and sewage outlet 8 is through the valve 9 that has been threaded.
Described filtering net 3 is an environment-friendly PE polyester mesh filter core.
Described poly-phosphate 7 is a food grade import poly-phosphate.
Method of use: a kind of back flushing pipeline of the utility model strainer when mounted; Earlier filtering net 3 is installed in the top of the pillar 6 in the urceolus 2; Quantitative food grade import poly-phosphate 7 is filled in the path 10 of urceolus 2 and filtering net 3 formation; Again loam cake 1 is screwed on urceolus 2 and the filtering net 3, valve 9 is installed in the below of urceolus 2, at last the utility model is installed on the pipeline.
Former water gets into the path 10 of urceolus 2 and filtering net 3 formation from the former water prosopore 4 of loam cake 1; Form monocycle or dicyclo inner complex through the calcium in food grade import poly-phosphate 7 and the water, magnesium, iron ion; Disperse incrustation scale; Through the filtration of filtering net 3, the inside that gets into filtering net 3 forms clear water again, and the clear water posticum 5 from loam cake 1 under the effect of hydraulic pressure flows out.
When regularly the utility model being cleaned, open valve 9, under the impact force action of water, the impurity in the strainer is gone out from sewage outlet, play the effect of back flushing, valve-off 9 after cleaning is accomplished, the utility model just can continue to use.
