Description

A kind of impurity cleaning slide sieve

Technical field

The present invention relates to chaff block screening plant field in rice, specially a kind of impurity cleaning slide sieve.

Background technology

In general, impurity removing has practical application in many fields, by taking grain processing rice enterprise as an example.By paddy The method that rice is processed into by husk rice polishing color sorting is commonly referred to as " rough go out white ", i.e., paddy of first hulling, paddy is become brown rice, then will Brown rice becomes rice, and color sorting rice finished product rice is polished to rice.

Wherein, polish using polishing machine, because polishing be rice in the polishing room of polishing machine by stainless steel riders with Rice wears, and wipes the chaff powder on rice surface, while rice makes rice surface with producing temperature in stainless steel riders friction process Starch keratinization, make rice glittering and translucent.Because in polishing process, chaff powder can form chaff block as rice enters rice stream together Enter finished product, while polish and can increase broken, produce small broken, rice crushed rices etc., before finished product packing, it is necessary to by these chaff blocks, rice crushed rices impurity from Separated in rice, the chaff block in rice, the cleaning of rice crushed rices are separated using special white rice grader, but increased at present Power consumption and the big space-consuming of equipment volume.

Utility model content

The technical problem that the utility model solves is to provide a kind of impurity cleaning slide sieve, and this slide sieve is chute type Unpowered slide sieve, it can be used to solve the shortcomings that in above-mentioned background technology.

Embodiment

In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.

Referring to a kind of preferred embodiment of Fig. 1 impurity cleaning slide sieve, in the present embodiment, slide sieve include support and The slide sieve main body being molded on support, slide sieve body top are connected with the charging aperture that a procedure gets off, and in charging aperture Paired buffer blanking plate is provided with to prevent the direct blanking of charging aperture from entering in slide sieve main body.

And be separated into three groups by the oblique column bar 4 of impurity and impurity screen cloth 12 in slide sieve main body and walk to expect passage, three groups are walked material Channel end is connected to bulky grain miscellaneous object outlet 7, rice product outlet 8 and little particle miscellaneous object outlet 13.Charging aperture is straight Be connected in succession three groups walk expect in passage on walk to expect the import of passage, and be additionally provided with one between passage with above walking to expect at it Overturn valve 10 and be used as aperture apparatus for regulating, this upset valve 10 adjusts briquetting 2 to carry out aperture adjustment by valve opening, leads to It is spacing overturn the maximum opening of valve 10 to cross positive stop 1, and walks to expect that the passage centre position of passage is provided with upper One rotation row brush 3, the width of rotation row brush 3 is consistent with the width for above walking to expect passage, and is left between the oblique column bar 4 of impurity 12mm gap limited doses and punishment in advance speed to facilitate.And the side of impurity screen cloth 12 is provided with tensioning bolt 11, to The tensile force and varicose face size for adjusting screen cloth prevent the rice to be excessively detained on screen cloth.

In the present embodiment, the oblique column bar 4 of impurity is used to separate bulky grain debris and rice, and sieve aperture thereon is mounting hole, These mounting holes and walk to expect that passage walks to expect that width is 1.3 ~ 1.6 times of grain widths to be sieved in oblique 40 ° settings between direction, and It is gradually reduced from the feed inlet end for above walking to expect passage to discharge port end slot size.And impurity screen cloth 12 be used for separate rice with it is small Particle debris, the aperture of its sieve aperture are 0.5 ~ 0.8 times of grain width to be sieved, and these sieve apertures walk to expect channel upper to going out from centre Material mouth end slot size gradually increases.The grain of rice can walk to expect passage by three groups when flowing down and three groups are walked to expect what is set between passage The oblique column bar 4 of impurity and impurity screen cloth 12 form automatic classification, walk to expect that the bulky grain of channel end is miscellaneous from above by bulky grain debris Thing outlet 7 is sifted out, and the rice after separation is walked to expect that the rice product outlet 8 of channel end sifts out from centre, and tiny debris and Rice bran then walks to expect that the little particle miscellaneous object outlet 13 of channel end sifts out from down.

Meanwhile safeguarded for convenience of slide sieve main body, walk to expect that the top of passage and end are respectively arranged with maintenance upper Hole, and closed in maintenance hole site by the first service hatch closed plate 5 and the second service hatch closed plate 6.

The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model Claimed scope is by appended claims and its equivalent thereof.
