Description

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

A device for mixing dry components of a concrete mixture [and.with. 852582 USSR], comprising 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 mixing materials, the content of which in the mixture differs by an order of magnitude or more.

Closest to the proposed invention is a screw mixer (model SS 60, SS 120) [http://www.teh-lib.ru/tpip/shnekoviy-smesitel.html].

The mixer contains loading and unloading devices, a horizontal housing, parallel shafts with spiral guides located in the housing.

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

The objective of the invention is the creation of an apparatus for mixing bulk materials of a relatively simple design having high quality mixing of materials, the content of which in the mixture differs by an order of magnitude or more.

The task is achieved in that in the apparatus for mixing bulk materials containing loading and unloading devices, a horizontal housing with a cover, 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.

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

Figure 2 shows a section aa.

Figure 4 shows a top view.

The apparatus for mixing bulk materials contains loading devices 1 and 2, a horizontal housing 3, with a cover 4, parallel shafts 5 located in the housing with spiral guides 6 made of a set of elastic elements. On the inner surface of the housing 3, parallel to the shafts, a guide device 7. is installed. In the housing cover, additional loading devices of one of the materials 8 are installed (the content of the mixture is greater). The drive of the shafts 5 is carried out from the electric motor 9 through a chain transmission, which tells the shafts to rotate in opposite directions. The finished mixture enters the discharge device 10.

The apparatus for mixing bulk materials is as follows. Bulk materials to be mixed come from the loading devices 1 and 2 into the internal volume of the housing 3 where they are captured and sprayed by spiral guides 6 mounted on the shafts rotating in opposite directions 5. The rarefied flows thus formed are directed towards each other. The mixing process occurs when mixed materials move in streams, as well as when interacting with the apparatus body, in the process of moving particles due to the execution of guides in the form of spirals. At this stage, the preparation of the preliminary mixture. When the mixture moves along the case with spiral guides in certain areas, the second component is supplied (installation zone of the first additional loading devices 8). Here, the next portion of the material is introduced into the mixture, the content of which is greater, and subsequent mixing. Further, when passing through the following additional loading devices 8, a new portion of a larger material is introduced. When the mixture reaches the opposite side of the body, it is unloaded into the unloading device 10. Due to the presence of the guiding device 7, the particles are mixed in the entire volume of the apparatus, there is a good contact of the interacting rarefied flows.

The proposed apparatus for mixing bulk materials allows for low energy consumption and relatively small dimensions to ensure good mixing of bulk media. The apparatus is most suitable for introducing small quantities of one bulk material into a large volume of the second, with obtaining a good quality mixture.
