Description
Technical field
The present invention relates to a kind of filter, especially a kind of self-cleaning filter.
Background technology
Self-cleaning filter is that a kind of filter screen that utilizes is directly tackled the impurity in water; remove water body suspension, particle; reduce turbidity; purify water, reduce the generations such as system dirt, bacterium algae, corrosion, to purify water and the normal equipment of working of other equipment of protection system; water enters self-cleaning filter body by water inlet; due to intelligentized design, system can be identified Impurity deposition degree automatically, gives blowoff valve signal automatic pollution discharge.Self-cleaning filter is at water treatment field, to apply equipment more widely at present, and it simply designs and good performance makes sewage reach best filter effect.Pollutant holding capability that self-cleaning filter overcomes traditional filtering product is little, be subject to that dirt stops up, filtration fraction needs disassembly, cleaning and cannot monitor filter state etc. numerous shortcomings, there is the function of former water being filtered and automatically filter core being cleaned blowdown, and while cleaning blowdown, system uninterruptedly supplies water, and automaticity is very high.Self-cleaning filter, Operation and control does not need just cleaning and filtering automatically of external any energy, automatic pollution discharge.Can be vertical, horizontal, be inverted any direction optional position and install, can be used for all trades and professions water filtrations such as industry, agricultural, municipal electric power, electronics, medicine, food, printing and dyeing, building, iron and steel, metallurgy, papermaking.
Existing self-cleaning filter, often has complicated structure.Its operation principle is as follows: pending water enters body by water inlet, and the Impurity deposition in water, on stainless steel filtering net, produces pressure reduction thus.By pressure difference switch, monitoring intake-outlet pressure reduction changes, when pressure reduction reaches setting value, electric controller, to hydraulic control valve, drive motors signal, causes following action: motor drives brush rotation, filter core is cleaned, control valve is opened and is carried out blowdown simultaneously, and whole cleaning process only need continue tens of seconds, when cleaning end, closed control valve, motor stops operating, and system returns to its original state, starts to enter next filter progress.Its structure is too complicated, and cost is higher, can not apply widely, is especially not suitable for the comparatively underdeveloped place of economy.
Summary of the invention
The problem to be solved in the present invention is to improve the problem that structure is too complicated, cost is higher of a kind of self-cleaning filter in background technology.
In order to overcome the above problems, the invention provides a kind of self-cleaning filter, comprise columniform outer sleeve, be placed in the filter core of the cylindricality in outer sleeve, water inlet, described outer sleeve is provided with standby water inlet, pure water inlet, outlet of sewer, described self-cleaning filter also comprises cross over pipe, parallel pipe, cleaning hose, described water inlet is located on cross over pipe, described cross over pipe is communicated in many parallel pipes simultaneously, described many parallel pipes are all parallel with outer sleeve and be uniformly distributed circumferentially in outer sleeve around, between every parallel pipe and outer sleeve, be provided with the many cleaning hoses that are communicated with them, described cleaning hose is uniformly distributed along parallel pipe length direction, many cleaning hoses on described every parallel pipe are parallel to each other and are right against filter core.
The outlet of described cleaning hose is provided with turbine, and turbo blade is provided with many furs towards a side of filter core, and the length of described fur is greater than its root to the distance of filter core.
Described turbo blade is provided with a plurality of through holes, and described through hole is between the root of fur.
A kind of self-cleaning filter of the present invention, comprise columniform outer sleeve, be placed in the filter core of the cylindricality in outer sleeve, water inlet, described outer sleeve is provided with standby water inlet, pure water inlet, outlet of sewer, described self-cleaning filter also comprises cross over pipe, parallel pipe, cleaning hose, described water inlet is located on cross over pipe, described cross over pipe is communicated in many parallel pipes simultaneously, described many parallel pipes are all parallel with outer sleeve and be uniformly distributed circumferentially in outer sleeve around, between every parallel pipe and outer sleeve, be provided with the many cleaning hoses that are communicated with them, described cleaning hose is uniformly distributed along parallel pipe length direction, many cleaning hoses on described every parallel pipe are parallel to each other and are right against filter core, by many cleaning hoses on many parallel pipes, intake simultaneously, utilize branch's current of water inlet filter core to be played to the effect of flushing, sewage is got rid of from the outlet of sewer of outer sleeve lower end.A kind of self-cleaning filter of the present invention, can reach the effect of self-cleaning without external power supply, simple in structure, easy to use, cost is lower, reliable and stable.

The specific embodiment
Below in conjunction with accompanying drawing, a kind of self-cleaning filter of the present invention is described further.
As Fig. 1, shown in Fig. 2, the self-cleaning filter of the present embodiment, comprise columniform outer sleeve 5, be placed in the filter core of the cylindricality in outer sleeve 5, water inlet 1, outer sleeve 5 is provided with standby water inlet 2, pure water inlet 3, outlet of sewer 4, self-cleaning filter also comprises cross over pipe 12, parallel pipe 6, cleaning hose 7, water inlet 1 is located on cross over pipe 12, cross over pipe 12 is communicated in many parallel pipes 6 simultaneously, many parallel pipes 6 are all parallel with outer sleeve 5 and be uniformly distributed circumferentially in outer sleeve 5 around, between every parallel pipe 6 and outer sleeve 5, be provided with the many cleaning hoses 7 that are communicated with them, cleaning hose 7 is uniformly distributed along parallel pipe 6 length directions, many cleaning hoses 7 on every parallel pipe 6 are parallel to each other and are right against filter core.By many cleaning hoses on many parallel pipes, intake simultaneously, utilize branch's current of water inlet filter core to be played to the effect of flushing, sewage is got rid of from the outlet of sewer of outer sleeve lower end.If without to filter element cleaning, can close outlet of sewer 4.In addition, if water inlet 1 has been gone bad, can use standby water inlet 2, at this time, just there is no the effect of self-cleaning.A kind of self-cleaning filter of the present invention, can reach the effect of self-cleaning without external power supply, simple in structure, easy to use, cost is lower, reliable and stable.
In the present embodiment, the outlet of described cleaning hose 7 is provided with turbine, and turbo blade 8 is provided with many furs 9 towards a side of filter core, and the length of fur 9 is greater than its root to the distance of filter core.This design utilizes the feature rotating under water impact of turbine, drives fur to scrub filter core, and fur is along with rotation and the flowing of current of turbine are constantly scrubbed filter core, and its self-cleaning effect further improves.That described fur can be that carbon fiber or other are not allowed is easily broken, strength and toughness is compared with good material.
In the present embodiment, described turbo blade 8 is provided with a plurality of through holes 11, and through hole 11 is between the root of fur 9.Because fur is along with the rotation of turbine is rotated, and its length is longer, is sometimes easily intertwined.This design is circulated between fur by the current of through hole 11, plays the combing of fur and the effect that separates, prevents that fur tangles knotting, or snarly fur is rinsed and come, and reaches the preferably effect of long-term self-cleaning.
The invention is not restricted to above embodiment and conversion.
