RU2335336C1 - Device for mixing loose materials - Google Patents

Abstract

FIELD: processes.

SUBSTANCE: aggregate for mixing and compacting of loose materials is intended for application in the chemical industry and other branches, where preparation of high-quality mixtures is required. The aggregate contains dispensing systems, the unloading device, the drive, the case with a chisel and the shaft with a disk inside. The paddles with windows are attached to the disk. Thereat edges are mounted on a chisel surface, and the conic mounting attachment having elastic elements on an external surface is placed over the disk. The windows in the paddles are located in chessboard order. Construction simplification, blending and compacting improvement of quality is reached.

EFFECT: construction simplification, quality increase of blending and compacting.

Description

The present invention is intended for use in the chemical industry, agriculture, the production of building materials and other industries.

A known unit for mixing bulk materials containing dispensers, a mixing device in the form of a blade shaft and a conveyor belt located in the housing [RF Patent No. 2132723, BI No. 19, 1999, IPC 6 A01C 1/00]. The disadvantages of this device include the complexity of the design, as well as the friction of the blades on the tape, leading to rapid wear.

Closest to the proposed invention is an aggregate for mixing bulk materials containing dispensers, an unloading device, a drive, a housing, in the internal volume of which a bump stop and a shaft with a disk are attached, to which blades with windows are attached. The unit also contains a funnel and drums with parallel axes, on the surface of one of which there are radial elastic elements [RF Patent No. 2242272, BI No. 35, 2004, IPC B01F 3/18]. The disadvantages of this device include the complexity of the design and the low quality of mixing.

The disadvantages of this unit include the complexity of the design and low mixing efficiency.

The objective of the invention is to provide an aggregate for mixing bulk materials having a simple structure, high quality mixing and sealing and small size.

This object is achieved by the fact that in the unit for mixing and compaction of bulk materials containing dispensers, an unloading device, a drive, a housing, in the internal volume of which there is a chipper and a shaft with a disk, to which blades with windows are attached, fins are installed on the surface of the chipper, and a conical nozzle is placed above the disk, having elastic elements on the outer surface, the windows in the blades being staggered.

Figure 1 shows the unit for mixing bulk materials.

Figure 2 shows a view A.

The unit for mixing bulk materials contains a housing 1, in the inner volume of which there is a bump 11 with ribs 12, and also a shaft 2, with a disk 3 mounted on it with blades 9 and a conical nozzle 4. On the surface of the conical nozzle elastic elements are placed 5. In the blades 9, windows 10 are arranged in a checkerboard pattern. The shaft 2 is equipped with a drive 6. In the upper part of the housing 1 are dispensers of bulk materials 7 and 8, and in the lower discharge device 13.

The unit for mixing bulk materials is as follows.

Bulk materials to be processed are fed by dispensers 7 and 8 into the housing 1, onto the surface of the rotating conical nozzle 4, where under the action of centrifugal force they move to its base, interacting with the elastic elements 5. When materials move through the elastic elements, they are mixed. Further, particles of materials enter the surface of the blades 9 and move along them, pass through the windows 10 and fall on the surface of the next blade. From the blades, the particles break down and hit the surface of the bump 11 with ribs 12, and are sent to the discharge device 13.

The high quality of the mixture in the mixing device is achieved due to the joint processing of bulk materials during their interaction with the surface of the chipper and ribs, movement in a rarefied state in the form of a torch and movement on the surfaces of the blades, flying from the blade to the blade through the windows, as well as when moving through elastic elements located on the surface of the conical nozzle.

The claimed unit for mixing bulk materials has small dimensions, structurally simple, can provide high performance.
