Description

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

Known unit for mixing bulk materials, containing a belt conveyor with a drive, sequentially placed above the tape dispensers and adjoining rollers with elastic elements, equipped with a rotary drive, impact elements. The elastic elements are installed at an angle to the surface of the rollers - cross to cross, and the fender elements are made of a set of plates fixed in the upper part with the possibility of rotation, and equipped with elastic elements [RF Patent No. 2559470, IPC B01F 3/18, publ. 08/10/2015, BI No. 22].

The disadvantages of this mixer include a relatively low quality of mixing.

Closest to the proposed invention is an aggregate for mixing bulk materials containing dispensers, an unloading device, a housing, a bumper and a shaft with a disk located in the housing, and rotary motion drives. A flange is placed above the disk, to which elastic elements are attached, and the bumper is made corrugated and equipped with deformation devices [RF Patent No. 2321447, IPC B01F 3/18, publ. 04/10/2008, BI No. 10].

The disadvantages of this mixer include the low quality of mixing.

The objective of the invention is to create a device for mixing bulk materials, providing high mixing efficiency.

The task is achieved by the fact that in the proposed device for mixing bulk materials containing dispensers, an unloading device, a drive shaft with a disk to which elastic elements are attached, a bumper made of corrugated and equipped with deformation devices.

Distinctive design features of the proposed invention are that the elastic elements are made in the form of double flat plates of different heights, connected in the area of attachment to the disk, and a curvilinear guide device is installed under the dispensers, in the lower part in contact with the elastic elements.

On FIG. 1 shows a diagram of a device for mixing bulk materials.

The device for mixing bulk materials contains dispensers 1 and 2, an unloading device 3, a drive shaft 4 with a disk 5, to which elastic elements 6 and 7 are attached, a bump stop 8, made corrugated and equipped with deformation devices 9.

The elastic elements 6 and 7 are made in the form of double flat plates of different heights, connected in the area of attachment to the disk 5. Under the dispensers 1 and 2, a curvilinear guide device 10 is installed, in the lower part in contact with the elastic elements 6 and 7. The shaft 4 is driven from electric motor 11.

Device for mixing bulk materials works as follows.

Bulk components to be mixed are supplied by dispensers 1 and 2 to a curvilinear guide device 10, which directs them to the capture zone by elastic elements 6 and 7, rotating together with the drive shaft 4 and disk 5. When the mixed materials move along the curved surface of the guide device 10, they are premix.

Elastic elements 6 and 7 transfer the mixed materials into a dispersed flow, which hits the bumper 8, which is made corrugated and equipped with deformation devices 9. Reflected from the bumper 8, the mixture is poured into the unloading device 3.

Due to the fact that the bump stop 8 is made corrugated and equipped with deformation devices 9, particle reflections occur at different angles, and the deformation of the bump stop 8 leads to a constant change in the trajectories of particle reflection.

Due to the fact that the elastic elements 6 and 7 are made in the form of double flat plates of different heights, connected in the area of attachment to the disk 5, they deform differently when interacting with the surface of the guide device 10 of a curvilinear shape. Elastic elements 6, having a greater height, deform more strongly than elastic elements 7. This makes it possible to provide particles with different velocities, both in modulus and in direction, when sprayed by elastic elements 6 and 7, that is, a dispersed flow of mixed materials with different speeds and trajectories of particles, which improves the quality of mixing.

Thus, in the proposed device for mixing bulk materials, due to the fact that the mixing of materials occurs when they move in a dispersed flow at different speeds and directions, impact interaction with a bumper that constantly changes its shape, and movement in a reflected flow, a high quality of mixing is achieved. .

The proposed device for mixing bulk materials has a high mixing quality.
