Description
Technical field
A kind of back-flushing filtering device for snow-ice melting system sprinkling system is the utility model is related to, belongs to pipeline mistake
Field is managed in filtering.
Background technology
, typically can be in centrifugal pump to extend the service life of pipe fitting or nozzle in snow-ice melting system sprinkling system
Delivery port installs filter to filter out the impurity in water.And a large amount of impurity can be accumulated in filter core after filter long-time use,
Cause filter core to block, reduce the efficiency of filtering.
In order to solve the above problems, improve the efficiency of filtering, it is necessary to periodically take out filter filter core be rinsed or
Filter core is changed, it is highly inconvenient.It can also be solved the above problems using the filter with backwashing function, but with backwashing function
Filter cost it is high, because its is complicated, filter core is changed also relatively difficult once damaging.Based on this, this practicality is new
Type designs a kind of simple back-flushing filtering device based on plain filter.
The content of the invention
（One）Technical problems to be solved
To solve the above problems, the utility model proposes a kind of for the backwashed of snow-ice melting system sprinkling system
Filter device.
（Two）Technical scheme
Back-flushing filtering device of the present utility model for snow-ice melting system sprinkling system, including main pipeline, branch pipe,
Accelerator, the first valve, the second valve, filter, blowoff valve, blow-off pipe, the 3rd valve；The 3rd is provided with the main pipeline
Valve, filter, the second valve；The branch pipe both ends are held respectively to be connected with main pipeline, and one end is located at before the 3rd valve, another
End is provided with accelerator and the first valve between filter and the second valve, on branch pipe；The blow-off pipe connects with main pipeline
Connect and between the 3rd valve and filter, blowoff valve is provided with blow-off pipe.
As preferential technical scheme, first valve, the second valve, blow-off pipe and the 3rd valve are stop valve.
（Three）Beneficial effect
Compared with prior art, it has the advantages that the utility model：The utility model is used for pavement snow melting
The back-flushing filtering device of change ice sprinkling system is simple in construction, and simple to install is easy to use, and developing result is good, can reduce hair punching
The cost of filtration system is washed, extends the service life of filter.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings；
Fig. 1 is the structural representation for the back-flushing filtering device of snow-ice melting system sprinkling system.
1- main pipelines；2- branch pipes；3- accelerators；The valves of 4- first；The valves of 5- second；6- filters；7- blowoff valves；
8- blow-off pipes；The valves of 9- the 3rd.
Embodiment
A kind of back-flushing filtering device for snow-ice melting system sprinkling system as shown in drawings, including main pipeline 1,
Branch pipe 2, accelerator 3, the first valve 4, the second valve 5, filter 6, blowoff valve 7, blow-off pipe 8, the 3rd valve 9；The supervisor
The 3rd valve 9, the valve 5 of filter 6 and second are provided with road 1；The both ends of branch pipe 2 are connected with main pipeline 1 respectively, one end position
Before the 3rd valve 9, the other end is located between the valve 5 of filter 6 and second, and the valve of accelerator 3 and first is provided with branch pipe 2
Door 4；The blow-off pipe 8 and main pipeline 1 are connected and between the 3rd valve 9 and filter 6, and blowdown is provided with blow-off pipe 8
Valve 7.
Wherein, first valve 4, the second valve 5, the valve 9 of blow-off pipe 8 and the 3rd are stop valve.
Back-flushing filtering device of the present utility model for snow-ice melting system sprinkling system, during normal work, the 3rd
Valve and the second valve are opened, and the first valve and blowoff valve are closed, and water flows out through the 3rd valve filter, the second valve；Recoil
When washing work, the 3rd valve and the second valve are closed, and the first valve and blowoff valve are opened, after the accelerated device of water accelerates, through first
Valve, filter, blowoff valve outflow, complete the flushing of impurity in filter core.
A kind of back-flushing filtering device for snow-ice melting system sprinkling system of the present utility model, have beneficial below
Fruit：The back-flushing filtering device that the utility model is used for snow-ice melting system sprinkling system is simple in construction, simple to install, user
Just, developing result is good, can reduce the cost of hair flushing filtering system, extends the service life of filter.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New spirit and scope are defined.On the premise of the utility model design conception is not departed from, ordinary people in the field couple
The all variations and modifications that the technical solution of the utility model is made, the scope of protection of the utility model, this reality all should be dropped into
With new claimed technology contents, all record in detail in the claims.
