Description

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

A device for sealing bulk materials, containing rotating rolls with cells on the outer surface and shells of elastic material, covering the rolls from the outside, tension and breaker rollers [a.s. USSR No. 1368021, MKI B03J 2/22, 1988].

Closest to the proposed invention is an aggregate for mixing and compaction of bulk materials, comprising a conveyor belt with a drive, sequentially placed dispensers and mixing devices with elastic elements, equipped with a rotary motion drive, a drum with radial elastic elements and a drive, a fixed surface [RF patent No. 2241530 , BI No. 34, 2004, IPC B01F 3/18].

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

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

The task is achieved in that in the unit for mixing and compaction of bulk materials containing a belt conveyor with a drive, dispensers, an unloading device and mixing devices having elastic elements and equipped with a rotary motion drive, the belt conveyor drive drum has cells and a shell of elastic material, and the dispensers, the unloading device and the mixing device are placed in the internal volume of the conveyor belt, and the mixing device is presented vlyayut wheels are located along the lower branch of the conveyor belt and having on the end of the elastic members.

Due to the fact that the elastic elements are located at the ends of the mixing devices, there is an intense interaction of the elastic elements with the components being mixed, which leads to the formation of a high-quality mixture. Due to the fact that the dispensers, the unloading device and the mixing device are located in the internal volume of the conveyor belt, this unit has small dimensions. Due to the fact that the drum of the conveyor belt has a cell and a shell of elastic material on its surface, the bulk material is compacted in the cells of the drive drum, and in the discharge zone, the shell straightens and directs the compacted mixture to the discharge device.

Figure 1 shows a device for mixing and sealing bulk materials.

Figure 2 shows a view of A.

The unit for mixing and compaction of bulk materials contains a conveyor belt consisting of a belt 3, a driven drum 2, a drive drum 1 with a sheath 4 and a drive 10, dispensers 8 and 9, mixing devices 7 provided with a rotary movement drive 6, an unloading device 5.

The unit for mixing and compaction of bulk materials works as follows. Bulk materials to be processed are fed by dispensers 8 and 9 onto the inner surface of the belt. The material moves in a thin layer along with the tape. When the tape moves under the mixing devices 7, the material on it is intensively mixed. The mixing device is driven from the drive 6. The material, passing in the gap between the drive drum 1 and the tape 3, takes the form of cells and is compacted. The finished product is unloaded through the unloading device 5.
