Description

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

A device for granulating agricultural products [Avt.sv. USSR No. 1386277, B01J 2/12, 1984] containing devices for loading components and unloading granules, a frame on which is mounted a horizontal container formed by disks fixed to the shaft and covering them with an endless belt, tension and drive rollers. The blades are placed on the surface of the tape. Despite the fact that this unit is not intended for mixing bulk materials, it is close in design to the invention.

The disadvantages of this device include the complexity of the design, the inability to obtain a high-quality mixture and high energy consumption.

Closest to the invention is a mixer [RF Patent No. 2191622, B01F 3/18 publ. 10.27.2002], containing devices for loading mixed components and unloading the finished mixture, a frame on which a horizontal tank is installed, formed by disks fixed to the shaft and covering them with an endless belt, tension and drive rollers. The blades are placed on the surface of the tape. Fixed horizontal rollers are installed inside the mixer.

The disadvantages of this mixer include the design complexity and low quality of mixing and high energy consumption.

The objective of the invention is to provide a device for mixing bulk materials having a fairly simple design, allowing to obtain a mixture of high quality.

The problem is achieved in that in a device for mixing bulk materials containing a device for loading mixed components and unloading, a frame on which is mounted a container formed by disks mounted on the shaft and covering the tape, the drive, the tape from one end is rigidly fixed, and the second end communicates with the traction drum, fixed racks with vertical grooves are placed on the sides of the tape, in which the shaft ends are installed, and a window is made for unloading the mixture in the surface of the tape.

In FIG. 1 shows a device for mixing bulk materials.

In FIG. 2 shows the initial (upper) position of the shaft with the disks.

In FIG. 3 shows the final (lower) position.

In FIG. 4 shows view A.

A device for mixing bulk materials contains a device for loading the mixed components 1 and 2, an unloading device 3, a frame 4 in the form of fixed racks 5 with grooves 6. The materials are mixed in a container formed by disks 8 fixed to the shaft 7 and covering them with a tape 9.

Two disks 8 are mounted parallel to each other at the end sections of the shaft 7. The tape 9, interacting with the lower side surfaces of the disks 8, forms a container open at the top for mixing materials.

At one end, the tape is rigidly fixed, and the second end communicates with the traction drum 10. To unload the mixture in the surface of the tape made window 11.

The device operates as follows.

At the beginning of the mixer shaft 7 with disks 8 is in the upper position; the tape is wound on the traction drum 10. Next, the traction drum 10 is driven into rotation and the tape, reeling from it, lowers the shaft with the discs down. Mixed materials come from the loading devices 1 and 2 into the internal cavity of the container formed by disks 8 fixed on the shaft 7 and covering them with tape 9. When the container moves downward, materials are poured and circulated, which contributes to their intensive mixing.

The mixture is unloaded through a window on the surface of the tape when it reaches its lower (extreme) position.

Due to the fact that one end of the tape is secured, the second communicates with the traction drum, and fixed racks with vertical grooves are installed on the sides of the tape, in which the shaft ends are installed, plane-parallel movement is communicated to the shaft and discs, which ensures the formation of zones in the internal volume intensive circulation of mixed materials.

The proposed device for mixing bulk materials has a fairly simple design, low energy consumption and provides homogeneous mixtures, including prone to sticking, agglomeration.

Claims (1)
