Description

. Предлагаетс экспрессный способ просеивани продуктов помола зерна и любых других продуктов дроблени и обогащени , характеризующийс тем, что продукт направл етс па плоские сита толстым слоем, превышающим обычный в 2-5 раз и проходит по ситам длинный путь в вихревом состо нии при сохранении на всем прот жении пути посто нную толщину сло .. An express method is proposed for sifting the products of grinding grain and any other products of crushing and enrichment, characterized in that the product is guided on flat screen sieves in a thick layer 2-5 times longer than usual and passes through the sieves a long way in a vortex state while maintaining the path is a constant thickness.

На фиг. 1, 2, 3 показано осуществление способа.FIG. 1, 2, 3 shows the implementation of the method.

Сохранение посто нной толщины сло может быть осуществлено следующими пут ми:Maintaining a constant layer thickness can be accomplished in the following ways:

1.На горизонтальных плоских рамах, рассева с гребешками, но с клиновидной формой каналов 1, 2 и 3 (фиг. I), степень сужени которых рассчитываетс в соответствии с содержанием прохода в продукте, поступающем на сито, и ходом процесса просеивани .1. On horizontal flat frames, scattering with scallops, but with a wedge-shaped shape of channels 1, 2 and 3 (Fig. I), the degree of narrowing of which is calculated according to the content of the passage in the product entering the sieve and the course of the sifting process.

2.На наклонных -плоских рамах рассева без гребешков, но также с клиновидной формой каналов (фиг. 2), причем размер а больше и с больше d.2. On oblique -flat frames of sieving without scallops, but also with a wedge-shaped channel (Fig. 2), with the size a being larger and c larger than d.

3.На горизонтальных и наклонных рамах рассева, соответственно с гребешками или без гребешков, с пр моугольной формой канала, нос направлением сходовых продуктов из большего числа каналов в меньщие , суммами поперечных сечений каналов, уменьшающимис ст пен51ми , как показано на фиг. 3 (сумма сечени каналов b меньше а, с меньше d и d меньше с).3. On horizontal and inclined frames of sieving, with or without scallops, respectively, with a rectangular canal shape, bowing direction of products from a larger number of canals to smaller ones, with sums of cross sections of the channels, decreasing by foam, as shown in FIG. 3 (the sum of the cross section of the channels b is less than a, c is less than d, and d is less than c).

Claims

1. Express method of sifting grinding products of grain and other crushing products on flat screen sifters, characterized in that the processed product is directed to sieves

a thick layer of 40-100 mm (for flour) and passes an elongated path in a dry condition while maintaining a constant path throughout the entire course (-th layer thickness.

2. The form of making the method according to claim 1, distinguishing that the horizontal flat sieves of the sifters divide the screens into successive channels that gradually taper along the path of the product being sieved, so that the thickness of the layer remains constant .

3. The form of the method according to claim 1, characterized in that the inclined or horizontal flat sieves of the wedge-shaped form of the sifters are installed successively one after the other, with their gradual narrowing along the way of sifting the product, or set; several individual sieves are poured with a gradual decrease their numbers in each successive stage of screening.
