Abstract

The invention relates to suspension flow dividers and allows improving the quality of suspension separation by reducing clogging of the grate sieve (CC) 7. The device includes a housing 1, a feeding nozzle (P) 2, mounted horizontally, and a partition 3, placed between 4 and output P 5. Inside the housing 1 on the horizontal axis 6 placed above P 2, the COP 7 is mounted with a cantilever with the possibility of rotation between the P 2 and the partition 3. The grates of the COP 7 are alternately placed in (L IsD CX) O) 00

Description

two planes intersecting on the axis of rotation of the CS 7. The size of the gap between the partition 3 and the end of the COP 7, which is in the position furthest from P 2, is equal to the largest size of the gap between adjacent grates. The initial suspension through P 2 under pressure enters CS 7. The suspension passes into the gaps between the grate and is sent to the flow D of flow 6300

The invention relates to suspension flow dividers installed directly in pipelines or at the inlet of density meters and other similar devices, where the separation of a suspension into two streams is required, one of which (without foreign inclusions) is analyzed, for example, for determining the density.

The aim of the invention is to improve the quality of the separation of the suspension by reducing the clogging of the grate.

Fig. 1 schematically shows a device for separating a suspension; FIG. 2 is a view A of FIG. 1;

The device comprises a housing 1, a horizontally-mounted supply nozzle 2, a partition 3 placed between the discharge nozzle 4 for the purified material and the outlet nozzle 5 for the crude material. Inside the housing 1, on a horizontal axis 6, placed above the supply nozzle 2, the grate 7 can be rotated in a cantilever manner, which can swing within an angle c. determined by the limiters 8 of the rotation of the sieve, between the supply nozzle 2 and the partition 3. The grate 7 of the sieve 7 is alternately arranged in two planes intersecting on the axis of rotation of the sieve. The size of the gap between the partition and the end of the sieve, which is in the position furthest from the nozzle 2, is equal to the largest size of the gap between adjacent sieves 7.

The device works as follows.

The initial suspension, containing large foreign particles and fibrous impurities, through a horizontal supply nozzle 2 under pressure falls on a sieve 7, which is deflected from the supply nozzle 2 and forms an angle ft with the vertical. Upon entering the sieve 7, the slurry passes into the gaps between the grate 7 of the sieve and is sent to the discharge nozzle 4 for collecting the stream for analysis. Large foreign particles and fibrous impurities slide down along the working surface of the grate and due to the fact that the force vector of gravity of the particles is directed downward, detached from the grate and directed with a part of the flow to the outlet. When the surface of the screen 7 is gradually clogged, the frontal resistance of the jet increases, due to which the screen 7 deflects, the angle increases and more favorable conditions are created for removing impurities from screen 7. The maximum angle cJ. The sieve 7 is deflected to one of the stops 8 on the housing 1. After the particles are removed from the surface and washed off, the cycle repeats, i.e. the sieve 7 is constantly swaying, which contributes to the effective cleaning of its surface from foreign inclusions. When the screen 7 reaches the furthest from the supply nozzle 2, the position between its end and the partition 3 remains a gap, the value b of which is equal to the largest gap between the grates of the screen. This gap is necessary in order not to between the sieve and the partition. The suspension rings got stuck, which can lead to solid particles clogging the sieve, which have already passed into the gap between the sieve grate 7.
