Technical field

The invention belongs to edible oil storing technology fields, more particularly to a kind of edible oil tank that can clear up filter membrane automatically to exhale Inhale valve.

Background technique

It is generally fitted with breather valve on the storage tank of edible oil, balance is adjusted to the pressure in oil tank, in order to Guarantee edible oil oil quality, additionally mounted filter device is also wanted on breather valve, to avoid breather valve open valve into When row pressure is adjusted, the impurity in external environment is entered in storage tank, causes the pollution of edible oil.

The filter device of gravity type breather valve is typically mounted at the outside of exhalation valve and the bottom of inlet valve, works long hours Afterwards, the impurity such as dust are easily adhered on the filter membrane on the outside of exhalation valve, filter membrane is caused to block, reduce the circulation effect of air, it is right The regulating effect of exhalation valve adversely affects, will be on filter membrane although exhalation valve can blow out air-flow when adjusting work outward Partial impurities are blown off, and still, exhalation valve is not that the lengthy pressure always all in adjustment state, inside and outside tank all keeps steady Periodically, the filter membrane on the outside of exhalation valve be just easy to because it is static for a long time in air due to dirty blocking, when filter membrane blocking is serious, To influence whether the normal regulating of exhalation valve, the pressure in tank can not be discharged in time, and cause storage tank to expand, there are security risk, And there is no filter membrane automatic cleaning apparatus for the most breather valve in market, are not only cleared up by manually carrying out periodic cleaning Trouble, and human cost is improved, the breather valve that small part can clear up automatically is also the electrical and pneumatic device used, is needed It expends electric power energy to be driven, not only increases use cost, and there is also the problems of safety circuit safety.

Then, in view of this, being studied improvement for existing structure and missing, the food that can clear up filter membrane automatically is provided With oil tank breather valve, to achieve the purpose that with more more practical value.

Summary of the invention

In order to solve the above technical problem, the present invention provides one kind can clear up the edible oil tank breather valve of filter membrane automatically, To solve in edible oil tank, the filter membrane on the outside of exhalation valve is easy to be blocked, and there are problems that security risk.

One kind of the present invention can clear up the purpose and effect of the edible oil tank breather valve of filter membrane automatically, by technology in detail below Means are reached:

A kind of edible oil tank breather valve that can clear up filter membrane automatically, including valve body, the top movable installation of the valve body There is an exhalation valve disc, the top of the valve body and is located above exhalation valve disc and is fixedly installed with rain shade, the bottom of the rain shade Portion is fixedly connected with the center-pole extended to below exhalation valve disc, and the bottom of the exhalation valve disc is fixedly connected with support ring, institute State and be equipped with filter membrane in support ring, it is described exhalation valve disc inside and be located at center-pole on the outside of be rotatably connected to turntable, it is described It breathes out the inside of valve disc and is located on the outside of turntable and be rotatably connected to pivoted housing, the inside of the exhalation valve disc and be located at the outer of pivoted housing Side is rotatably connected to equally distributed scraper plate, the top of the valve body and is located on the outside of exhalation valve disc and is fixedly installed with strainer, The bottom of right section of the valve body is movably installed with sucking valve disc, right section of the valve body and is located at the fixed peace in lower section of sucking valve disc Equipped with filter bowl, the bottom of left section of the valve body is fixedly connected with flange.

Further, the valve body is mounted on edible oil tank by flange, and the exhalation valve disc and sucking valve disc are equal Be mounted on valve body by guide post, the top of the valve body and be located at exhalation valve disc on the outside of be provided with drag ring, play close Envelope effect, while the sundries on the outside of filter membrane can be scraped off, slope is provided at the top of the valve body, the sundries conveniently scraped off It slides.

Further, the center-pole and exhalation valve disc be located in same vertical central lines, on the outside of the center-pole under Section is thread segment, offers screw thread corresponding with center-pole on the inner wall of the turntable, above and below exhalation valve disc is along center-pole When mobile, turntable can be rotated with.

Further, it is provided with teeth on the outer wall of the turntable, is provided on the inner wall of the pivoted housing corresponding with turntable Interior teeth, be provided with outer teeth corresponding with scraper plate on the outer wall of the pivoted housing.

Further, the scraper plate includes outside plate, and the internal activity of the outside plate is plugged with multiple scrapers, and pacifies on scraper Equipped with spring, the bottom of the scraper offers slope, so that scraper moves down and when with valve body contact, can inwardly receive automatically Contracting, the outside plate are provided with rack gear when pivoted housing rotates close to the side of pivoted housing and are rotated by rack drives scraper plate, the scraper plate It is movably arranged on exhalation valve disc by fixing axle.

Further, the filter hole of large aperture is offered on the strainer, for filtering the sundries of bulky grain, while macropore The strainer of diameter is not easy to be blocked.

Compared with prior art, the invention has the following beneficial effects:

1. filtering out the sundries of bulky grain by the way that strainer is arranged in the outside of exhalation valve disc, the aperture of filter hole on strainer It is larger, be not easy to be blocked, while the primary filtration through filter screen, further reduced filter membrane be blocked a possibility that, by Filter membrane is arranged to avoid the little particle sundries in external environment from entering edible oil tank inside in the lower section of exhalation valve disc, works as exhalation valve When disk moves up and down progress pressure adjusting, breathes out the scraper plate in valve disc and rotate and stretch out, wiper is carried out to filter membrane, will be adhered on filter membrane Sundries clean up automatically, reduce filter membrane be blocked a possibility that, improve the safety of breather valve.

2. the drag ring on valve body first can carry out wiper to filter membrane, so that outside filter membrane during exhalation valve disc moves down The sundries of side by constantly it is upward, then scraper rotation stretches place to filter membrane carry out wiper, filter membrane outer upper end is assembled miscellaneous Object pushes away, and is both provided with slope by the way that scraper plate to be designed as to the combining form of multiple scrapers, and below each scraper, works as scraper When with the tip contact of valve body, scraper can successively be entered by valve body extruding, when the scraper of lower section is entered by valve body extruding, top Scraper is still carrying out wiper, and therefore, the scraper of multisection type is more thorough to the cleaning effect of filter membrane.
