At present, the filter that strainer screen is cleaned mainly contains two types, and a kind of is back flush type, and another kind is self-cleaning type.
Some achievements in research of domestic self-cleaning filter can complete the automatic cleaning of filtering dirt impurity to a certain extent, but its cleaning mechanism or transmission mechanism need external force to drive, be generally motor, maybe need to set up larger blowdown chamber, increased the manufacturing cost and use cost of filter.
The disclosed back flush type filter of Chinese patent CN202270401U, its operation principle is to realize impurity residual on filter screen is carried out to backwash cleaning through the direction of filter screen by changing current, although this backwashing manner can be realized the self-cleaning to filter screen, but effect is bad, a lot of intractable impurity still can remain on filter screen, affects filter effect, particularly, the hydraulic pressure that backwash process is had relatively high expectations, has improved cost and energy consumption greatly.
The disclosed auto-flushing well strainer of Chinese patent CN201565186U, although be to clean by brush and filter screen friction while cleaning filter screen, but during its work, need to be divided into two stages, be filtration stage and wash phase, this can cause within a certain period of time, filters the shortcoming that the work period shortens.Except above shortcoming, in brush brush filter screen process, due to Water Pressure, cleaning performance is also also bad.
Therefore, a kind of simple in structure, good reliability, low cost movement, the filter that can automatically clean again, filter continuously work is suggested.
Summary of the invention
The utility model relates to a kind of filter, it is characterized in that: comprise filter screen (6) and two end plates (4) at least, filter screen (6) is a cylindricality cylindrical body, end plate (4) is positioned at the two ends of shape cylindrical body, end plate (4) and filter screen (6) form one and filter cavity, on at least one end plate (4), be provided with delivery port (2), make water to be filtered see through filter screen (6) from outside and enter in filtration cavity, then discharge from delivery port (2); End plate (4) is provided with rotating shaft A(3), the filtration cavity that filter screen (6) and end plate (4) form is by rotating shaft A(3) to be fixed on fixed mount (1) upper, and A(3 around the shaft) rotation.
Above-mentioned filter screen (6) can be cylindrical tube shape body, can also be multi-edge column-shaped cylindrical body, is preferably cylindrical tubular body.
As improvement, above-mentioned filter screen (6) is preferably provided with axial blade (5) on outer one week.
As improvement, above-mentioned filter screen (6) is preferably provided with cleaning device, and cleaning device can be located at the inside of filtering cavity, also can be located at the outside of filtering cavity, can also be located at simultaneously and filter the inside and outside of cavity, above-mentioned cleaning device water flushing device.
The concrete structure of above-mentioned water flushing device is as follows: at least comprise water inlet pipe (11), water inlet pipe (11) is provided with rinse mouth (12), the water outlet direction of rinse mouth (12) is filter screen (6) surface, and described water inlet pipe (11) is by support B(13) be connected with fixed mount (1).
Actual use is as follows: the filtration cavity being comprised of filter screen (6) and end plate (4) is by being located at the rotating shaft A(3 on end plate (4)) be fixed on fixed mount (1), filtration cavity is put into and treated overanxious water, treat that overanxious water sees through filter screen and enters overanxious cavity, the water after overanxious is discharged overanxious cavity by delivery port again.
Compared with prior art, the utlity model has simple in structure, good reliability, operating cost is low, and can automatically clean, the feature such as continuous filtration.
