Abstract

A slide sieve comprises a sieve body (1) and is characterized in that the sieve body (1) is obliquely arranged with a certain angle formed by the length direction and the horizontal plane. A mesh screen (2) is arranged in the length direction of the sieve body (1), a feeding port (11) is formed in the upper end of the sieve body (1), a discharging port (14) is formed in the lower end of the sieve body (1), and an impurity outlet (13) is formed in the bottom of the sieve body (1) below the mesh screen (2). The mesh screen (2) is arranged in the sieve body (1), clean wheat enters the sieve body (1) through the feeding port (11), broken wheat is sieved through the mesh screen (2) and then discharged from the impurity outlet (13), and generated wheat skin dust is sucked away from an air suction port (12). The slide sieve is simple and reasonable in structure and convenient to use and install without efforts, impurities contained by the clean wheat can be effectively reduced, and precision and quality of wheat gluten can be improved.

Description

A kind of slide sieve

Technical field

The utility model relates to flour production technical field, especially a kind of for the slide sieve to clean wheat removal of impurities.

Background technology

In Flour production process, wheat flour milling technique be three sieves two make a call to two de-stones one selected three water, in wheat flour milling cleaning process, wheat enters cleaning sieve through bucket elevator, carry out first screening and selection by winnowing, remove most of thick, thin and light assorted, then carry out first except stone, remove in major part thick and stone shoulder to shoulder, thresh wheat again, after threshing wheat, enter second screening and selection by winnowing, it is lower assorted during wheat scourers are laid, broken wheat and light assorted removing, after water, dampener sends into wheat wetting storehouse, after wheat wetting, carry out the processing of second de-stone, remove tiny stone assorted, entering second threshes wheat, after threshing wheat, enter tertiary screen choosing and selection by winnowing, remove the impurity on wheat.In said process, wheat will pass through the equipment such as elevator, wheat scourers, elephant trunk before entering clean wheat bin, in this process, can cause a little wheat shorts and wheat skin dust, this has just increased the impurity content of clean wheat, although passed through tertiary screen choosing, impurity content average out to 0.8% left and right of clean wheat, enters to grind the impurity content of passages through which vital energy circulates in order to reduce wheat, the precision that improves flour, need to design a kind of suitable screening plant and meet the needs of production.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of simple and reasonable, easy to use, effective slide sieve of impurity elimination is provided for the above-mentioned state of the art.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of slide sieve, comprise sieve nest, it is characterized in that: the length direction of described sieve nest and horizontal plane are angled to be obliquely installed, in sieve nest, be provided with along its length a screen cloth, in sieve nest upper end, be provided with charging aperture, the lower end of sieve nest is provided with discharging opening, and the bottom of the sieve nest below screen cloth is provided with impurity outlet.

As improvement, described screen cloth is located at the middle part of sieve nest, and sieve nest is divided into two parts that communicate up and down by screen cloth, and the cross section that its middle and upper part is divided is trapezoidal, and lower part is four jiaos of downward-sloping vertebra shapes, and described impurity outlet is arranged on the corner position of these four jiaos of vertebra shapes.

As improvement, on the sieve nest of described charging aperture below, be also provided with one and be connected with air exhauster for the inlet scoop that wheat skin dust is siphoned away.

Improve, the lower end of described sieve nest is corresponding to the position undergauge triangular in shape of screen cloth again, and described discharging opening is located at the tail end of triangle undergauge.

Improve, the length direction of described sieve nest and the angle of horizontal plane are 20～60 ° again.

Further improve, the left and right sides of described sieve nest is respectively equipped with the hanging of being convenient to installation.

Compared with prior art, the utility model has the advantage of: in sieve nest, be provided with screen cloth, clean wheat enters in sieve nest by charging aperture, after by screen cloth, broken wheat etc. being sieved, from the impurity outlet of bottom, discharge, the wheat skin dust producing is sucked away from inlet scoop.The utility model is simple and reasonable, uses installation all very convenient, and without power, can effectively reduce into mixing containing of mill passages through which vital energy circulates, improves precision and the quality of gluten.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is left view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

As shown in Figure 1, 2, a kind of slide sieve, comprise sieve nest 1, the length direction of described sieve nest 1 and horizontal plane are angled to be obliquely installed, in sieve nest 1, be provided with along its length a screen cloth 2, in sieve nest 1 upper end, be provided with charging aperture 11, on the sieve nest 1 of charging aperture 11 belows, be also provided with one and be connected with air exhauster for the inlet scoop 12 that wheat skin dust is siphoned away, the lower end of sieve nest 1 is provided with discharging opening 14, and the bottom of the sieve nest below screen cloth 21 is provided with impurity outlet 13; Screen cloth 2 is located at the middle part of sieve nest 1, sieve nest 1 is divided into two parts that communicate up and down by screen cloth 2, the cross section that its middle and upper part is divided is trapezoidal, charging aperture 11 and inlet scoop 12 are successively set on the upper surface of trapezium structure, lower part is four jiaos of downward-sloping vertebra shapes, described impurity outlet 13 is arranged on the corner position of these four jiaos of vertebra shapes, and in the lower end of sieve nest 1, corresponding to the position undergauge triangular in shape of screen cloth 2, described discharging opening 14 is located at the tail end of triangle undergauge; The length direction of described sieve nest 1 and the angle of horizontal plane are 20～60 °, for the ease of installing, be respectively equipped with in the upper and lower side left and right sides of sieve nest the hanging 3 of being convenient to installation.

During use, slide sieve is to tilt to install, clean wheat is poured into from charging aperture 11, clean wheat along the screen cloth 2 tilting toward lower slider, the fine impurities such as some wheat shorts from screen cloth 2 fall into sieve nest 1 part, finally from impurity outlet 14, discharge, and some wheat skin dusts in clean wheat are kicked up when entering slide sieve, from inlet scoop, 12 are sucked out, and garbled clean wheat is discharged and enters clean wheat bin from the discharging opening 14 of slide sieve lower end.

Through actual production, use, what install clean wheat after slide sieve of the present utility model additional is reduced to 0.6% containing assorted from original 0.8%, and whole process is without power, very easy to use, greatly reduce into mill passages through which vital energy circulates containing assorted, improved precision and the quality of gluten.
