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 (RU 2459405 C1, A01F 12/46, 08/27/2012), containing a stabilizing tank, outlet channels made in the vertical side wall of the stabilizing tank and separated by slats, a housing with a vertical partition, pipes.

A disadvantage of the known device is the low flow rate due to the discharge of bulk material through a vertical wall with outlet channels of a limited area. This leads to an increase in the vertical dimensions of the device, which limits the scope of its application, in particular, in existing grain cleaning complexes.

A device for separating the flow of bulk materials (RU 25200341 C1, A01F 12/44, 06/20/2014), containing a stabilizing tank, a housing with a vertical partition and laths forming outlet channels located in the form of an upstream cascade (selected as a prototype).

A disadvantage of the known device is the low flow rate characteristic associated with the distribution of bulk material in the stabilizing tank and the cavity of the box at an angle of repose, which limits the number of exhaust channels located in the form of an ascending cascade. The increase in the width of the outlet channels will lead to unfilled outflow of bulk material and reduce the quality of the separation of the stream. The increase in the length of the outlet channels will lead to a significant increase in the negative effect on the quality of the separation of the flow of the asymmetry factor of the flow of bulk material supplied to the stabilizing tank. The increase in flow characteristics due to the number of outlet channels inevitably leads to an increase in the vertical dimensions of the device, which significantly limits the scope of its application, in particular, in grain cleaning technologies.

The purpose of the invention is to increase the flow rate characteristics of the device for separating the flow of bulk materials.

This goal is achieved in that in a device for separating the flow of bulk materials containing a stabilizing tank, outlet channels separated by strips, a housing, nozzles, according to the invention, the strips are placed in a horizontal plane with equal pitch at the same level with the bottom of the stabilizing tank, and the nozzles are installed symmetrically relative to the body.

The invention is illustrated by drawings, where in FIG. 1 shows a general view of a device for separating the flow of bulk materials, FIG. 2 is a view A in FIG. 1, in FIG. 3 is a section BB in FIG. 2.

A device for separating the flow of bulk materials contains a stabilizing tank 1, outlet channels 2, straps 3, housing 4, nozzles 5.

A device for separating the flow of bulk materials works as follows.

Bulk material is supplied with a certain flow characteristic Q to the stabilizing tank 1. As it accumulates, the bulk material enters the cavity of the housing 4 and is discharged into the nozzles 5 through the outlet channels 2. The symmetrical arrangement of the nozzles 5 relative to the width of the housing 4 and, accordingly, the length of the outlet channels 2 divides the area of the outlet 2 channels in half, which allows you to divide the flow of bulk material into two equal parts (Q / 2) and direct them into two pipes 5.

With an increase in the supply of bulk material to the stabilizing tank 1, the number of activated exhaust channels 2 and the height of the layer of bulk material above them increase, respectively, the material flow through the nozzles 5 increases. When the supply of bulk material to the stabilizing tank 1 decreases, the number of used exhaust channels 2 decreases and the flow rate of loose material through the nozzles 5. Thus, the process of automatic control of the flow characteristics of the device for separating the flow of bulk x materials. The placement of the strips 3 in a horizontal plane with an equal step at the same level with the bottom of the stabilizing tank 1 allows you to multiply increase the number of exhaust channels 2 in comparison with the cascade placement of the strips (according to the prototype) with equal levels of bulk material in the stabilizing tank 1. Thus, a significant increasing the expenditure characteristics of the device for the separation of bulk materials while maintaining the vertical overall dimensions of the device, which is essential when limiting technological height in production conditions, in particular, when layout equipment in grain cleaning complexes.
