Description

The invention relates to ore dressing equipment and can be used in the coal, ore industry and other sectors of the economy.

A distribution and distribution device is known, which contains a feed nipple and a chute expanding in the course of the material movement with partitions mounted on its bottom at an angle to each other.

The disadvantage of this device is the unreliability of work in connection with the filling of the gutter when working on a material with a particle size of more than 15 mm.

The aim of the invention is to increase reliability and efficiency by preventing seizure of the gutter.

This goal is achieved by the fact that in a loading and distributing device that contains a supply pipe and a chute that expands as the material moves, with partitions mounted on its bottom at an angle to each other, the partitions are made in the form of an angular profile, the inner sides of the shelves are directed to the supply pipe and installed with the formation of transverse rows along the length of the gutter, and the partitions of one row are opposed to the intervals between the partitions of another row of ..

In addition, the shelves of the corner profile in their upper part are directed toward the supply nozzle.

FIG. 1 shows the described device, a longitudinal section; in fig. 2 - section A-A of FIG. one.

The loading and distributing device includes a casing 1 with a supply nozzle 2 and a chute 3 placed inside the casing 1. The chute 3 is filled with a spur along the material movement and has partitions 4 mounted on its bottom. Partitions 4

They are made in the form of a corner profile, the inner sides of the shelves of which are directed to the supply nozzle 2. In this case, the angle between the shelves is selected for each specific case. In addition, the shelves in their upper part have a bevel, also directed to the supply nozzle 2. The partitions 4 are installed with the formation of transverse rows along the length of the groove 3. At the same time, the partitions 4 of one row are opposite the gaps between the partitions of the other row.

The number of partitions 4 and their rows depends on the size of the gutter 3. Thus, with a gutter width of 3 to 2 m, three partitions 4, installed in two rows, are sufficient.

Boot-switchgear works as follows.

Through the feeding nozzle 2 of the casing 1, the material is fed to the chute 3. Due to the inclination of the chute 3 and the oscillation of the screen, the material moves down the chute 3, meets the partition walls 4 in the form of corner profiles forming the pockets, and fills them. As the material accumulates in the pockets, it begins to pour over the partitions 4. Since the shelves of the partitions 4 are made with a bevel directed toward the supply nozzle 2, the material is first of all passed through the peripheral part of the partitions 4, and with further accumulation of the material length.

The proposed distribution switchgear is simple in design, has small dimensions and can be used in screens and separators without significant modernization.

The construction and arrangement of the partitions prevents seizing of the gutter, increasing the reliability and efficiency of the device.
