The filter belt flushing system of belt thickener press filter
Technical field
The utility model relates to sewage treatment area, specifically a kind of filter belt flushing system of belt thickener press filter.
Background technology
Belt thickener press filter is a kind of sewage-treatment plant, its main use principle is in the sewage in entering belt thickener press filter, to add flocculant to carry out the Chemical Pretreatment dehydration, then the sewage after making to process is through strainer filtering mud, mud forms mud cake on strainer, and the sewage after filtration is discharged.After sewage disposal completes, on strainer, filter cake is removed, and then by filter belt flushing system, strainer is cleaned.Existing filter belt flushing system adopts a plurality of nozzle water sprays to be rinsed strainer, and a plurality of nozzles 2 are to be arranged side by side between the water inlet pipe 1 at two ends, and the water inlet at a plurality of nozzles 2 middle parts is communicated with (see figure 1) successively.Mainly there is following shortcoming in this filter belt flushing system: owing to cleaning selected water body, be 1, sewage treatment plant's treated water body, also exist other impurity in water body, these impurity are plug nozzle very easily, affects normal wash and sprays; 2, in a plurality of nozzles, one of them nozzle, drops on strainer when excessive due to hydraulic pressure, not only can affect the filter effect of strainer, and the nozzle water yield of the nozzle ends dropped can become greatly, causes whole spraying hydraulic pressure to diminish, and affects cleaning performance.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of filter belt flushing system of belt thickener press filter, and it selects the high-pressure outlet with hole for water spraying to be cleaned strainer, has solved the problem that original nozzle easily stops up or drops.
The technical solution of the utility model is:
The filter belt flushing system of belt thickener press filter, include spray equipment and the water inlet pipe that is connected in the spray equipment end, and described spray equipment is selected high-pressure outlet, is provided with a plurality of hole for water sprayings on the sidewall of described high-pressure outlet.
Be provided with a plurality of layouts in a row and hole for water spraying downward on the sidewall of described high-pressure outlet.
Advantage of the present utility model:
The utility model is simple in structure, easy to use, adopts the high-pressure outlet with hole for water spraying to replace original nozzle arrangements, the water outlet stable water pressure of its each hole for water spraying; When cleaning strainer, the water inlet pipe water inlet that also only need open an end gets final product, and the water inlet control mode is simple; While as need, cleaning the utility model, also only need smash logical hole for water spraying with steel wire or other cleaning member and get final product, without being changed, reduce maintenance cost.
