Description
Technical field
The utility model relates in the fields such as oil, chemical industry, smelting, water treatment a kind of filter often using, and exactly relates to a kind of filter can automatic on-line cleaning.
Background technology
In petrochemical industry, smelt and water treatment etc. relates in the industry of pipeline transportation process, filter is an indispensable device, in producing at present, widely used filter is T-shaped filter or y-type filter, this filter has solved the problem that pipeline medium filters substantially, but medium is thick facing, when dirty complex situations, existing filter is owing to being subject to the restriction of this body structure, lack monitoring means and effectively on-line cleaning measure, finally fail to clear up in time the impurity in filter and result in blockage, cause equipment to be stopped transport, have a strong impact on production, in addition rapid establishment officer is cleaned, the operating personnel's that increase labour intensity.Visible, due to the shortage of monitoring means, operating personnel cannot predict the dirty stifled order of severity of filter interior at all, and existing technology also just rests on to be out of order and processes in this aspect again, has buried serious potential safety hazard to production.
For the problem of above-mentioned T-shaped filter or y-type filter existence, Chinese patent " oil strainer ", the patent No. is that 201110323861.X has openly proposed a solution, described in text as open in it: a kind of oil strainer, comprise filter body and filter core, described filter body comprises oil-in, oil-out, filter cylinder and top cover, and filter cylinder is the open-topped cylindrical straight tubular structure of bottom lock, oil-in is fixed on filter cylinder top, and oil-out is fixed on filter cylinder bottom; Cartridge interior centre position is provided with the boss for filter core is installed, filter core is detachable to be arranged on boss, filter core is the plate-like structure with filter opening, and filter core is separated into filter cylinder upper and lower two shape chambeies between oil-in and oil-out, and top cover is fixedly mounted on filter cylinder top.When filtering fluid, opens oil strainer oil-in, fluid enters shape chamber, filter cylinder top, fluid flows into the shape chamber of filter cylinder bottom through filter core, solid impurity is trapped within on filter core and realizes the filtration to fluid, and the clean fluid that process is filtered is from oil-out effluent oil filter.When oil system pressure raises 30% time, illustrate that clogging has appearred in the filter core of oil strainer, now oil filter needs to clean.Remove dirt for ease of user, the oil-in of closing oil strainer is next oily, then opens top cover, takes out filter core and carries out manual cleaning, has cleaned again filter core is fixed, and opens oil inlet and outlet and continues to put into operation.This technical scheme provides pressure detecting, by the inner case of filter " visual ", and change filter core into plate-like structure, save the inner space of filter cylinder, thereby increased the storage area of foul, this technical scheme can increase security reliability to a certain extent, has extended the working time of filter, reduce the wash number of filter, alleviate operating personnel's labour intensity.But owing to being subject to the restriction of structure, lack the theory of automation, the pressure monitoring that this technical scheme provides just plays one and monitors reminding effect, and do not apply it in the control of filter on-line cleaning, make this filter not obtain real technological innovation, still rest on existing that being out of order on the technological layer of processing again, potential safety hazard and labour intensity are not fundamentally resolved.
Summary of the invention
