Description

f 1

The invention relates to building technology, in particular, devices for beneficiation of useful minerals operating on the principle of flotation and gravity separation and intended for use in concentrating plants of ferrous and ferrous metallurgy, as well as in the mining and chemical industry.

A flow divider of a flotogravity machine, made in the form of a prism and consisting of a sequential set arranged diagonally in an alternate order of metal separating strips with a flat working surface rigidly connected to each other by means of metal square plates, is known. spacer sleeves and four studs 1J The specified flow divider is folded in construction and has high material consumption. : The closest in technical essence and the achieved result to the proposed is a divider of the flotation gravitational machine, including a set of sequentially arranged diagonally in an alternating order of separating strips with working and side surfaces made of wear-resistant elasic material, for example

The well-known flow divider is also complex in design and has a high material consumption, I will introduce the presence of a large number of different parts (square plastic, dividing strips, spacer sleeves and cones). In addition, it has insufficient bandwidth ,; since the whole living section of the divider is divided into channels with thick ends of square plates, which, during operation, the divider additionally swells and reduces the living section, which ultimately leads to the clogging of the channels with the enriched product.

The purpose of the invention is to increase the duration of the divider by increasing its working surface.

This goal is achieved by the fact that in the flow divider of the flotation and gravity machine, including a sequential set arranged diagonally in an alternating order of separation strips with workers and more

Troughs made of wear-resistant elastic material, grooves are made on the working surfaces of the dividing strips and transverse assembly grooves are on the side surfaces.

On the non-working surface of the dividing strips there is a chute, as well as a logical chute made on the working surface.

Figure 1 shows the flow divider, general view, axonometric; Fig. 2 is a spacer bar, axonometric and cross section; on fig.Z - flow diagram of the flow divider ,.

The flow divider is made in the form of a prism and consists of two extreme square plates with rounded corners 1 with openings in the centers of rounding for four tightening pins 2 with washers 3 and nuts 4. Between the extreme plates 1 on studs 2 diagonally arranged in alternate order are assembled dividing strips 5, each of which is made in one piece with two spacer sleeves 6, placed at the ends of one of the side surfaces of the slat 5. On the working and non-working surfaces of the slat 5 there are longitudinal grooves 7. On a rounded The two ends of the fastening holes 8, which coincide with the holes of the spacer sleeves 6, are made at the ends of the strip 5; The surfaces of each strip 5 have transverse grooves 9. A set of bars 5 is made so that two adjacent multidirectional bars 5 are in direct contact with each other by means of grooves 9, and two adjacent unidirectional bars - by means of spacer sleeves 6. Contact of spacer sleeves 6 with extreme plates 1 occurs. through elastic pads 10, the thickness of which is equal to two depths of the grooves 9.

The assembly of the flow divider is carried out in the following order.

Put the washers 3 on each end of the studs 2 and screw the nuts 4. Insert the ends of the studs 2 into the holes of one of the end plates 1. Flowed into two studs 2 with fastening holes 8 and 8 dividing the strip 5 so that its side surface on which there are no spacer sleeves 6, it is adjacent to the plate 1. After that, two three pins 2 put on two elastic pads 10 and the next button 5, so that the spacer sleeves 6 are rotated towards the plate 1, and the grooves 9 of both bars 5 are aligned . Analogously, in the same order, a complete set of separation planks 5 is produced in accordance with the required width of the divider. The total number of strips 5 must be even. After that, the ends of the pins 2 are put on the end of the plate 1 and through the washers 3 with nuts 4 they tighten the entire structure. Flow divider assembled. The pulp flow (shown in FIG. 3 by arrows) is a pad on the working surface of the splitter, the side walls of the grooves 7 of the separator bars 5 are divided into a series of jets, each of which is directed to the right or left (according to the fig) to the corresponding bath. The depth of the grooves 7 selected in accordance with the performance of the technological process in which the flow divider operates. In case of wear of the working surface of the strips 5, the divider is sorted out, turning the strips 5 so that the non-working surface becomes working. splitter. The grooves 9 are designed to overlap the working surfaces of adjacent multidirectional strips 5. Testing has shown that using the invention significantly simplifies the design of the proposed flow divider of the flotogravity machine compared to the known, reduces material consumption by 3.2 times, increases the living working section by 16% and increase the service life of the divider by 1.8 times.
