Abstract

The utility model relates to a self-cleaning filter which comprises a filtering chamber, a blow-down pipe (11), a pollution suction nozzle (6) and a blow-down rotary driving mechanism, wherein the blow-down pipe (11) is provided with a rotary blade (10). Compared with the prior art, as the blow-down pipe of the filtering chamber is provided with the rotary blade, the water flow near the blow-down pipe is driven to rotate in the self-cleaning process when the rotary blade rotates along with the blow-down pipe, the sediment accumulated at the bottom of the filtering net is accelerated to rotate, then the uniformity of the filtering liquid in the filter is maintained, and the pollution suction resistance of the sand suction assembly is lightened.

Description

Self-cleaning filter

Technical field:

The utility model relates to a kind of self-cleaning filter.

Background technology:

China's water resource is very short, and water resources ownership per capita is a world average level 1/4th only, and agricultural is the water rich and influential family, and therefore, the accelerated development agricultural water conservation is imperative, and the fast development of micro irrigation technology just requires advanced filter plant to adapt with it.

Existing slight irrigation automatic cleaning strainer is the trend of at present domestic and international filter research and development, but a lot of key technologies and equipment need further investigation, particularly cleaning the new achievement in research of urgent need on power and the cleaning way, therefore design a kind of good reliability, can economical operation, the filter that can clean automatically is very urgent again.

Chinese patent CN2636944, CN2774618Y, the disclosed automatic flushing well strainer of CN201120195Y, the main filter chamber that constitutes by filter housings, water inlet pipe, outlet pipe, blow-off pipe, tubular screen pack, in the filter chamber, be provided with the backwash mechanism that blowdown hollow shaft and suction nozzle constitute, on blow-off pipe, water inlet pipe and outlet pipe, be equipped with valve, can realize to take the function that filter can clean filter screen automatically apart.

But above-mentioned backwash net-type filter is because the filter chamber is simply single, when the canal river one class water source that contains plurality of impurities is filtered, normally reach different instructions for uses by changing different screen pack, and because when the state of filtration, the silt that filter screen inside is trapped falls in the gravity effect, can accumulate on the filter screen, hinder the rotation that filter screen bottom is inhaled husky assembly, influence the self-cleaning effect of filter.

Summary of the invention:

The utility model purpose is to provide a kind of self-cleaning filter that stops sedimentation on the filter screen.

The utility model comprises the filter chamber that filter housings (9), water inlet pipe (1), outlet pipe (4), blow-off pipe (8), valve (5), tubular screen pack (12) constitute, cartridge type blow-off pipe (11) in the filter chamber and the pollution-absorbing nozzle (6) on the cartridge type blow-off pipe (11), and the blow-off pipe rotary drive mechanism, it is characterized in that establishing on described filter chamber's central hollow shaft type blow-off pipe (11) rotating vane (10).

Above-mentioned rotating vane (10) along cartridge type blow-off pipe (11) but every group of monolithic setting.

Above-mentioned rotating vane (10) every group can be around the axle setting more than two along cartridge type blow-off pipe (11).

Above-mentioned blow-off pipe rotary drive mechanism can be for handle (13), also can be motor (14), can also be churning pipe (7).

Compared with prior art, the utility model is owing to install rotating vane on the blowdown hollow shaft of filter, when rotating vane rotates with the blowdown hollow shaft, near the blowdown axle current just can be driven to rotate in the self-cleaning process, the silt that filter screen bottom is gathered also is accelerated rotation, thereby keep the uniformity of self-filtering liquid, and alleviate the soil pick-up resistance of inhaling husky assembly.

The specific embodiment:

Embodiment 1:

With reference to Fig. 1, Fig. 2, present embodiment comprises filter chamber 1 and the filter chamber 23 that filter housings 9, water inlet pipe 1, outlet pipe 4, blow-off pipe 8, tubular screen pack 12 constitute, and the valve 5 on water inlet pipe 1, outlet pipe 4 and the blow-off pipe 8,23 centers, described filter chamber are provided with cartridge type blow-off

pipe

11,11 are provided with pollution-absorbing nozzle 6 and rotating vane 10 on the cartridge type blow-off pipe, its rotating vane 10 is provided with along 1 every group of monolithic of cartridge type blowdown management work, and the blow-off pipe rotary drive mechanism is a churning pipe 7.

Embodiment 2:

With reference to Fig. 3, Fig. 4, to compare with embodiment 1, the difference of present embodiment is, around the axle setting, the blow-off pipe rotary drive mechanism is a handle 13 to current rotating vane 10 along 11 every groups two of cartridge type blow-off pipes.

Embodiment 3:

With reference to Fig. 5, compare with embodiment 1, the difference of present embodiment is, difference is that rotating vane 10 is along 11 1 groups of monolithic settings of cartridge type blow-off pipe, the one group of rotating vane 10 in back be two around the axial symmetry setting, then rotating vane 10 repeats to be provided with this, and the blow-off pipe rotary drive mechanism is a motor 14.

Embodiment 4:

With reference to Fig. 6, to compare with embodiment 1, the difference of present embodiment is, around the axle setting, the blow-off pipe rotary drive mechanism is a motor 14 to rotating vane 10 along 11 every groups three of cartridge type blow-off pipes.
