Description

The invention relates to agriculture, namely, to the cleaning of grain and is intended to separate the flow of bulk materials.

A device for separating the flow of bulk materials (Tishaninov KN Methodology for studying the process of separating the flow of bulk materials / Improving the efficiency of agricultural machinery. - Collection of scientific works of GNU VIITiN, issue 7, Tambov, 2005, p. 46 ... 55), containing a stabilizing tank with holes in the bottom, taps placed in the taps and valves pivotally mounted on their walls, connected by a parallelogram mechanism and balanced by a counterweight.

The disadvantages of the known device are the low quality of the separation of the flow of bulk materials and the instability of the autoregulation zone due to the fact that the regulatory effect on the valves, determined by the height of the layer of bulk material in the stabilizing tank, is subjected to a random process of arch formation over the passage cross-section of the taps, and the relationship of the valves in the taps by means of a parallelogram the mechanism for their synchronous deviation requires articulating valves to different (lower and upper) walls bends. In this case, the ratio of flow rates through bends changes to the opposite depending on the angle of deviation of the valves from the plane of the cross section.

A device is known (selected as a prototype) for separating the flow of bulk materials (application No. 20111110258/21 from 03/17/2011), containing a stabilizing capacity, outlet channels on the side wall, communicating with the cavity of the housing, divided by a partition, nozzles.

A disadvantage of the known device is the low quality of the process of separation of the grain flow due to the asymmetric bulk material placed in the stabilizing tank of the monolith relative to the discharge channels when it is fed to the stabilizing tank by inclined material lines. Moreover, the supply of bulk material from the conditions of ensuring technological reliability of the process is carried out by an unfilled stream, which changes the geometric parameters of the cross section and its spatial position, which increases the asymmetry of the placement of bulk material in a stabilizing tank.

The purpose of the invention is to improve the quality of the process of separation of the flow of bulk materials.

This goal is achieved in that the device for separating the flow of bulk materials containing a stabilizing capacity, outlet channels on the side wall, communicating with the cavity of the housing divided by a partition, pipes, according to the invention, the device is equipped with a receiving neck with a circular cross section in its upper part, framed by a connecting flange, and oval - in the lower, placed by the larger axis of symmetry perpendicular to the side wall of the stabilizing tank.

The invention is illustrated by drawings, where figure 1 shows a General view of a device for separating the flow of bulk materials, figure 2 - section aa in figure 1, figure 3 - section bb in figure 1.

A device for separating the flow of bulk materials contains a stabilizing tank 1, on its side wall 2 there are discharge channels 3 in the form of slots with horizontal strips 4, connected to the cavity of the housing 5, having a vertical partition 6 and attached to the housing of the pipe 7, a receiving neck 8, attached straps 9 to the stabilizing tank 1, in the upper part of the receiving neck 8 is framed by a connecting flange 10.

The device operates as follows.

Grain is fed into the stabilizing tank 1 through the inlet neck 8. As the grain supply to the stabilizing tank 1 increases, the number of outlet channels 3 included in the work increases through which the grain flows out, increasing the discharge characteristics of the nozzles 7. When the grain supply to the stabilizing tank 1 decreases, the number of the outlet channels 3 included in the work and the discharge characteristics of the nozzles 7 decrease . Thus, the process of auto-regulation and maintaining the level of the stabilizing layer of grain in the required range of heights is carried out. The oval shape of the lower section of the receiving neck 8 placed by a larger axis of symmetry perpendicular to the side wall 2 of the stabilizing tank 1 concentrates the feed flow of bulk material in the Central zone of the stabilizing tank 1, ensuring its symmetrical placement relative to the vertical partition 6, thereby creating a condition for the qualitative separation of the flow of bulk materials at their expiration through the outlet channels 3.
