Description

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

A known mixer of bulk materials, comprising a housing, a cover on which a feeder with loading nozzles is mounted, a drive shaft with unloading blades fixed to it and a rotor made in the form of a disk, with concentrically arranged hollow truncated cones with height and angle generatrix to the base increases from the central part to the periphery. On the working surfaces of the inner and middle cones are windows that are bounded below by the surface of the disk. On the inner surfaces of the middle and outer cones, guide vanes are installed spiral-shaped, having a number of holes and a circular arc profile [RF patent No. 2246343, BI No. 35, 2004, IPC B01F 7/26]. The disadvantages of this device include the complexity of the design, low quality mixing.

Closest to the proposed invention is a device for mixing and compaction of bulk materials containing dispensers, belt conveyor, rollers with radial elastic elements, drive, drive and guide drums, sprockets, chain, drum with radial elastic elements and drive, fixed surface, container for collecting the finished product [RF patent No. 2241530, 2004, IPC B01F 3/18].

The device operates as follows.

Bulk materials to be mixed are dispensed onto the tape. The material moves in a thin layer along with the tape. When the tape moves under the drums, the material on it is intensively mixed. The drums are driven through a chain drive. From the tape, the material enters the sealing device, passing through which the finished product is obtained.

The disadvantages of this unit include the complexity of the design, low quality of mixing.

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

The task is achieved in that in the unit for mixing and compaction of bulk materials containing a conveyor belt with a drive, dispensers, a container for collecting the finished product, the guide drum of the conveyor belt is barrel-shaped, and a sealing plate made of elastic material is installed above the belt conveyor, and a mixing device having a housing and a drive shaft with a disk located inside the housing, on the surface of which elastic elements are placed.

Due to the fact that the guide drum of the conveyor belt is barrel-shaped, the conveyor belt is deformed in the discharge zone and the finished product is unloaded without sticking to the belt. The placement of elastic elements on the surface of the disk of the mixing device can significantly improve the quality of the mixture.

Figure 1 shows the unit for mixing and compaction of bulk materials.

Figure 2 shows a section aa.

Figure 3 shows a view of B.

The unit for mixing and sealing bulk materials contains dispensers 1 and 2, tape 3, drive 5, drive 6 and guide drum 7, the housing of the mixing device 8, shaft 9 with drive 14 and disk 10, on the surface of which elastic elements 13 are placed, a sealing plate 11, a container for collecting the finished product 4.

The unit operates as follows.

Bulk materials to be processed are fed by dispensers 1 and 2 to the rotary disk 10 of the mixing device, move under the action of centrifugal forces and interact with elastic elements 13 placed on its surface, are sprayed and hit the inner surface of the body 8 of the mixing device, which leads to intensive mixing of materials . The prepared mixture enters the conveyor belt and passes under the sealing plate 11, resulting in a compacted product, which is discharged into a container for collecting the finished product 4.
