Description
Technical field
The present invention relates to a kind of filter, particularly to a kind of variable gap backwash filter.
Background technology
What a lot of enterprises used at present remains traditional multi-layer sintering net and trapezoidal silk winded filtering core filter, this mistake
In filtering time-continuing process, the solid phase impurity in liquid is trapped in surface by filter element to filter, progressively deposits, and back flush is very
The solid phase impurity being trapped in surface by filter element is removed by hardly possible, finally results in filter element pressure at two ends difference and increases, filtration
Efficiency declines therewith.The filter of this quasi-tradition has following shortcoming: filtering accuracy is low；Filter element lost efficacy after it is necessary to more
The filter element renewing, or disassemble filter element and be carried out, cause whole system to shut down, stop production, so not only waste of manpower impact again
Being normally carried out of follow-up work requires it is impossible to meet commercial production seriality, and blowdown is difficult；Filter plant occupation of land is larger,
Cause space waste.
In order to overcome disadvantages mentioned above, recent domestic has developed the filter possessing self-cleaning function, this mistake
Not only floor space is little for filter, and can not interrupt filter successional filter element is carried out simultaneously, automatization
Degree is higher, saves human resourcess, so that filter efficiency is greatly improved.
Such as Chinese patent literature data discloses integral type self-cleaning filter [application number 201220683191.2；Award
Power notification number: cn203123646u], it includes valve body, valve gap and drainage screen, valve body and valve gap welding, and valve body is by blowdown section, change
Footpath section and outlet section are welded to form, and the blowdown section bottom of valve body is provided with sewage draining exit, filters slant setting in the filter, filters
Net is fitted with filter interior, and drainage screen is fixed it may be necessary to by drainage screen and valve body by valve body and valve gap reducing tube portion
Spot welding is fixed.The drainage screen of this kind of configured filter is flat filter net, even if being obliquely installed, the filtration work area of drainage screen
Still less, dirt-removing power is poor.And this drainage screen is in cleaning, because drainage screen is fixed in valve body, can only be using reversely
The method rinsed is rinsed to the impurity being attached on drainage screen, attachment, and the stainless steel cloth on filter element during flushing is variable
Weakened and emaciated body is bad, and the aperture in the Partial filtration hole on drainage screen becomes big, leads to filtering requirement when not reaching design, have more relatively
Big impurity cannot be filtered, and filter effect weakens, and can only be remedied it is clear that exist again by changing the method for drainage screen
The problem of the wasting of resources.
Therefore be directed to above-mentioned phenomenon, patent 203540174u refer to a kind of spring candle filter include one end be
Water inlet end, the other end is water side and the internal housing for cavity, and spring filter element is located in cavity, and spring filter element includes gear
Plate, lower baffle plate, connecting rod and some springs, one end of connecting rod is connected with overhead gage, and the other end is connected with lower baffle plate, every
One end of spring is all resisted against on overhead gage, and the other end is all resisted against on lower baffle plate.
Filter in said structure, is filtered as filter element using spring, has filter area greatly, dirt-removing power is strong
The advantages of, the size of impurity can be directed to simultaneously, so that overhead gage is moved up and down along connecting rod by rotating overhead gage, make spring pressure
Contracting or elongation, change the gap of spring inner, so that this spring filter element is suitable for filtering different size of impurity.
But using said structure when being adjusted, need to adjust spring-compressed by manually rotating overhead gage
Or elongation, inconvenient it is impossible to carry out consecutive production.
Content of the invention
