Description

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

A device for mixing the dry components of the concrete mix [AS. 852582 USSR, IPC B28C 5/36, publ. 08/07/1981], containing loading and unloading devices, a conveyor, parallel shafts with spiral guides located above the conveyor.

The disadvantages of this device include the complexity of the design and the low quality of the mixing of materials, the content of which in the mixture differs by an order of magnitude or more.

Closest to the proposed invention is an apparatus for mixing bulk materials containing loading and unloading devices, a horizontal housing with a lid, parallel shafts located in the housing, with spiral guides placed on them. Spiral guides are made of a set of elastic elements, on the inner surface of the housing, parallel to the shafts, a guide device is installed, and additional loading devices are placed on the housing cover above the spiral guides. [RF Patent No. 2555565, IPC B01F 7/00, publ. 07/10/2015, BI No. 19].

The disadvantages of this device include the low quality of mixing materials.

The objective of the invention is the creation of an apparatus for mixing bulk materials, having a high quality of mixing materials.

This task is achieved by the fact that we propose an apparatus for mixing bulk materials, containing a horizontal housing with a lid, loading and unloading devices, parallel shafts located in the housing with spiral guides placed on them,

Distinctive design features of the proposed invention is that the ends of the shafts are installed in hollow cruciform carriers, inside of which chain drives are placed connecting the sprockets on the shafts and the sprockets on the central axis installed along the horizontal housing, and the direction of the spirals of the spiral guides on adjacent shafts is opposite, and between coils of spiral guides on the shafts are equipped with elastic beaters, the length of which is greater than the height of the coils of spiral guides.

In FIG. 1 shows a diagram of an apparatus for mixing bulk materials.

In FIG. 2 shows view A.

In FIG. 3 shows an enlarged (2:1) inner cavity of the carrier with the chain drive.

Apparatus for mixing bulk materials contains a horizontal housing 1 with a cover 2, loading devices 3 and unloading 4, parallel shafts 5 located in the housing, with spiral guides 6 placed on them. 8 connecting sprockets 9 on shafts 5 and sprockets 10 on the central axis 11 installed along the horizontal body 1, and the direction of the spirals of the spiral guides 6 on adjacent shafts 5 is opposite, and between the turns of the spiral guides 6 on the shafts 5 there are elastic beaters 12, the length of which more than the height of the coils of the spiral guides 6. The drive of the shafts 5 is carried out from the electric motor 13 through chain drives 8. The drive of the cruciform carriers 7 is carried out from the electric motor 14. The mixture is unloaded through the unloading device 4.

Apparatus for mixing bulk materials works as follows.

Bulk materials to be mixed come from the loading devices 3 into the internal volume of the housing 1 and are concentrated in its lower part. Submission of materials is stopped.

Mixing occurs with repeated exposure to a mixture of spiral guides 6 and elastic beaters 12.

When the carrier 7 rotates, the materials of the spiral guides 6 and elastic beaters 12 located in the lower part of the body 1 alternately penetrate into the materials, rotating together with the shafts 5. The spiral guides 6 move the materials along the axis of the body, and the elastic beats 12 act in the circumferential direction (perpendicular to the axis of the body 1).

Due to the fact that the direction of the spirals of the spiral guides 6 on the adjacent shafts 5 is opposite, there is an alternate change in the direction of influence on the mixture, which leads to an increase in the quality of mixing.

Due to the fact that the length of the beaters 12 is greater than the height of the coils of the spiral guides 6, they are deformed against the inner walls of the housing 1, which leads to an intense effect on the particles of materials in the interturn space of the spiral guides 6, which contributes to the intensification of the mixing process.

For installation of internal organs, cleaning and repair, body 1 is provided with cover 2.

The proposed apparatus for mixing bulk materials allows for good mixing of bulk media.
