Description
Technical field
The utility model relates to a kind of filter, particularly a kind of variable gap backwash filter.
Background technology
What a lot of enterprise used at present remains traditional multi-layer sintering net and trapezoidal silk winded filtering core filter, this filter is in filtration time-continuing process, solid phase impurity in liquid is filtered element and is trapped in surface, progressively deposit, back flush is difficult to be trapped in surperficial solid phase impurity removing by being filtered element, finally cause filter element pressure at two ends difference to increase, the efficiency of filtration declines thereupon.The filter of this quasi-tradition has following shortcoming: filtering accuracy is low; After filter element lost efficacy, the filter core that must more renew, or disassemble filter core and clean, causes whole system to shut down, stops production, so not only waste of manpower but also affect normally carrying out of follow-up work, can not meet the requirement of industrial production continuity, and blowdown difficulty; Filter plant takes up an area comparatively large, causes space waste.
In order to overcome above-mentioned shortcoming, recent domestic has developed the filter possessing self-cleaning function, this filter not only floor space is little, and can not interrupt filter successional while, filter element is cleaned, automaticity is higher, saves human resources, and filter efficiency is improved greatly.
Such as Chinese patent literature data discloses integral type self-cleaning filter [application number 201220683191.2; Authorization Notice No.: CN203123646U], it comprises valve body, valve gap and screen pack, valve body and valve gap welding, valve body is welded to form by blowdown section, reducer and outlet section, be provided with sewage draining exit bottom the blowdown section of valve body, filter slant setting in the filter, screen pack and filter interior are fitted, screen pack and valve body spot welding, by valve body and valve gap reducer pipe partial fixing, can be fixed by screen pack if desired.The screen pack of this kind of configured filter is flat filter net, even if be obliquely installed, the filtration work area of screen pack is still less, and dirt-removing power is poor.And this screen pack is when cleaning, because screen pack is fixed in valve body, the method of back flush can only be used to rinse the impurity be attached on screen pack, attachment, the yielding damage of stainless steel cloth during flushing on filter core, the aperture in the Partial filtration hole on screen pack becomes large, cause filtering requirement when not reaching design, have more larger impurity cannot be filtered, filter effect weakens, can only be remedied by the method changing screen pack, obviously, there is again the problem of the wasting of resources.
Therefore for above-mentioned phenomenon, in patent 203540174U, refer to a kind of spring candle filter, to comprise one end be water inlet end, the other end is water side and the inner housing for cavity, spring filter core is positioned at cavity, spring filter core comprises overhead gage, lower baffle plate, connecting rod and some springs, and one end of connecting rod is connected with overhead gage, and the other end is connected with lower baffle plate, one end of every root spring is all resisted against on overhead gage, and the other end is all resisted against on lower baffle plate.
Filter in said structure, spring is adopted to filter as filter core, there is filter area large, the advantages such as dirt-removing power is strong, for the size of impurity, by rotating overhead gage, overhead gage can be moved up and down along connecting rod, making spring-compressed or elongation simultaneously, change the gap of spring inner, thus make this spring filter core be applicable to filtering the impurity of different size.
But adopting said structure when regulating, needing carry out regulating spring compression by rotating overhead gage manually or extend, not too convenient, cannot consecutive production be carried out.
