Description
Technical field
The present invention relates to a kind of filter, be specifically related to a kind of self-cleaning filter.
Background technology
Self-cleaning filter is widely used in the industries such as metallurgy, petrochemical industry, coal miner, papermaking, electric power. Traditional self-cleaning filter is to make medium with granule filter material, and it exists poor filtration effect, and failure rate of machinery is high, and line service amount is big, and the problems such as self-cleaning efficiency is low, and service life is short do not meet actual operation requirements.
Summary of the invention
Goal of the invention: the invention aims to overcome deficiency of the prior art, it is provided that a kind of overall operation is steadily reliable, good filtration effect, and regular maintenance is few, and self-cleaning efficiency is high, the self-cleaning efficient filter of long service life.
Technical scheme: in order to solve above-mentioned technical problem, a kind of self-cleaning efficient filter of the present invention, it includes vertical filter body, it is provided with low head at described vertical filter body lower part, top is provided with upper cover, described low head is welded and fixed with vertical filter body lower part and is connected, described upper cover and vertical filter body upper part pass through Flange joint, described flange is provided with bolt arrangement, at described vertical filter, this internal is provided with filter screen, described low head is provided with water inlet, described vertical filter body sidewall is provided with outlet, described upper cover is provided with back purge system, it is provided with drive motor at described back purge system top, it is provided with blow-off line on one side at described back purge system, described blow-off line is provided with blowoff valve. described water inlet is provided with water inlet flange.
Described outlet is provided with outlet flange.
Described outlet is arranged on vertical filter body sidewall middle and lower part.
Described filter screen is the 0.5mm filter screen filtering precision.
The present invention is vertical cylinder type structure, and front is provided with differential pressure control instrument, and muddy water from bottom to top flows out clear water supply user by filter screen from outlet through filter inlet. Filter foreign material, filtering residue when carrying out back-flushing operation, be automatically drained out outside device by blowoff valve.
Beneficial effect: compared with prior art, it has the remarkable advantages that the present invention: overall structure of the present invention is simple, and volume is little, each parts with the use of, operate steadily reliable, adopt 0.5mm to filter the filter screen of precision, good filtration effect, adopt back purge system, self-cleaning efficiency is high, and this hazard rate is low, sustainable continuous work, long service life, meets actual operation requirements.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, a kind of self-cleaning efficient filter of the present invention, it includes vertical filter body 1, it is provided with low head 2 in described vertical filter body 1 bottom, top is provided with upper cover 3, described low head 2 is fixedly linked with vertical filter body 1 lower weld, described upper cover 3 is connected by flange 4 with vertical filter body 1 top, described flange 4 is provided with bolt arrangement 5, it is provided with filter screen 6 in described vertical filter body 1, described low head 2 is provided with water inlet 7, described vertical filter body 1 sidewall is provided with outlet 8, described upper cover 3 is provided with back purge system 9, it is provided with drive motor 10 at described back purge system 9 top, it is provided with blow-off line 11 on one side at described back purge system 10, described blow-off line 11 is provided with blowoff valve 12, described water inlet 7 is provided with water inlet flange 13, described outlet 8 is provided with outlet flange 14, described outlet 8 is arranged on vertical filter body 1 sidewall middle and lower part, described filter screen 6 filters the filter screen of precision for 0.5mm. overall structure of the present invention is simple, and volume is little, each parts with the use of, operate steadily reliable, adopting 0.5mm to filter the filter screen of precision, good filtration effect, adopt back purge system, self-cleaning efficiency is high, this hazard rate is low, sustainable continuous work, and long service life meets actual operation requirements.
The invention provides a kind of thinking and method; the method and the approach that implement this technical scheme are a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications; these improvements and modifications also should be regarded as protection scope of the present invention, and all available prior art of each ingredient not clear and definite in the present embodiment is realized.
