Abstract

The invention relates to devices for the storage and unloading of bulk material and can be used in the food, chemical industry and other industries. The aim of the invention is to increase the equilibrium dimension of the outflow of material. When the bulk material is flowing out in the bunker, the discharge is created, which ensures that atmospheric air is sucked in by the upper end of the hollow spring 4, which comes out through the flow divider 5, naturally aerates the bulk material and eliminates countercurrent air filtration. When a dome is formed in the hopper, the conical bottom 3 is completely or partially freed from the impact of the bulk material, which allows the hollow spring 4 to move it upwards. At the same time, the turns of the hollow spring 4 and the conical bottom 3 with the flow divider 5, moving, ensure the destruction of the resulting roof. I 3. n. F-ly, 2 ill. § W СО 05 with to with

Description

The invention relates to devices for storing and unloading bulk material and can be used in the food, chemical industries and other sectors of the national economy.

The purpose of the invention is to increase the uniformity of the outflow of material.

FIG. 1 shows a silo for bulk materials; general view; in fig. 2 — node I in FIG. one.

A rial that allows the hollow spring 4 to move it up. At the same time, the turns of the hollow spring 4 and the conical bottom 3 with the flow divider 5, moving, ensure the destruction of the resulting roof.

If this mode of operation of the bunker does not provide equal dimensional discharging of bulk material (for example, prone to sticking), then a hollow spring 4 is supplied with a pulsating stream of compressed air, which is IJ VJjri 1. pers. I I Il II Jli lV / IV .CU., / VC4, IXVV

The bulk material hopper is the one that excites its oscillations. At the same time, from the housing 1, provided with supports 2 and air, exit the holes 10, which divide the conical bottom 3, and adapt the material sticking to the walls of the housing 1. At the same time, for cleaning the hopper axis and made in the form of a casing 1 with a smaller number of holes 10

Loy spring 4 with a flow divider 5, the latter 15 can be performed on turns

stacked hollow spring 4. The tension force of the hollow spring 4 is adjusted by means of a nut 9, depending on the properties of the material being unloaded.

The use of the proposed hopper allows to stabilize the flow of bulk

fixed at its lower end and having openings b, which are protected from the side of movement of the bulk material visors 7. In this case, the conical bottom 3 is mounted freely relative to the housing 1 and connected to the divider 5 flow. The gap between the casing 1 and the conical bottom 3 is closed from the outside with a flexible tape 8. The upper end of the hollow spring 4 is threaded and attached to the casing 1 by means of a nut 9. At the same time, it can be connected 25 to a source of compressed air or an atmosphere. In the coils of the hollow spring 4 is made holes 10, oriented toward the walls of the housing 1.

The hopper for bulk materials works as follows.

When the bulk material is flowing out in the bunker, the discharge is created, which ensures that atmospheric air is sucked in by the upper end of the hollow spring 4, which comes out through the flow divider 5, naturally aerates the bulk material and eliminates countercurrent air filtration.

When a vault is formed in the bunker, the conical bottom 3 is completely or partially freed from the influence of loose material.
