Description

The invention relates to agriculture and may find application for the preparation of a mixture of bulk materials, and also it is applicable in the food industry. The invention can also be used in construction for the preparation of solutions.

The preparation of homogeneous bulk mixtures is a widely used process in the production and processing of agricultural products.

The mixing process is carried out using elastic devices that create pulsating cycles of stress states in mutually perpendicular planes. Such pulsations cause combined mixing, including convective and diffusion mixing and minimizing segregation, since the segregation centers are destroyed during one mixing cycle.

A known method of preparing a mixture of bulk materials. RF patent No. 2345827, applicant and patent holder ΦGOU VPO AChGAA, application No. 2007113084, filed April 9, 2007, published February 10, 2009, bulletin No. 4. The method is carried out by creating pulses acting on the mixture. The disadvantage of this method is the low productivity and the inability to mix wet components.

Also known is a mixer comprising a traction means, an elastic shell, a housing, a component supply system. RF patent No. 2047340, B01F 013/00. The disadvantage of this device is the insufficiently high quality of mixing and low productivity.

The objective of the invention is to enable mixing of the wet components and improving the quality of mixing and increase productivity.

The problem is solved by the combined use of a group of inventions.

The technical effect consists in the fact that the method is carried out by a component mixing device consisting of a housing in which cavities are connected by two shells, interconnected, one cavity communicating with the feed system of the mixed components, and the second cavity in communication with the condensate collection system, two elastic shells are installed in the casing, both ends of each casing are hermetically fixed along the perimeter of the casing in the pipe, and a drum is installed in the cavities formed by the bent sections of the shells Ana, which interact with the sections of the shells connecting the fixed ends of the shells, the drums connected by couplings with shafts that are kinematically connected to the engines, while the cavities formed by the shells are in communication with the collection system of the finished mixture.

The method of mixing the components using the device includes a cyclic effect on the components to be mixed by rolling the elastic shell, while mixing the components, the resulting mixture is periodically evacuated to ensure its drying, squeezed and squeezed into an expanding cavity.

The drawing shows a device for implementing the method. The device is made of a housing 1 made of a closed pipe. In the housing 1, elastic shells 2, 3 are placed, interacting with the drums 4, which are connected by shafts 5 to the shafts 6. The shafts 6 are kinematically connected to the motors (not shown). The ends 7 of the shells 2, 3 are hermetically fixed around the perimeter of the housing 1 in the pipe 8. The shells 2, 3 form cavities 9, 10, interconnected by a pipe 11, which is connected through the valve 12 to the ready-mix system 13. The cavity 10 is in communication with the mixed component supply system 14. The cavity 9 is in communication with the condensate collection system 15.

The implementation of the method.

A mixture of four components was prepared: A, B, C and C. The percentage of each component is 25% of the total. Humidity of each component is 10%. The method was carried out by the device depicted in the drawing. The diameter of the pipes 8 is 500 mm. The course of each shell is 5 m. The frequency of movement of shells 2, 3 was 1 cycle in 120 seconds. The engine rotates the drums 4 reversely, with which shells 2, 3 are rolled through the pipe 8 back and forth. Shells 2, 3 are filled with compressed air. The system 14 for feeding the mixed components into the cavity 10 serves mixed components. The shells 2, 3 enter the cavity 10 and push the mixed components out of it through the pipe 11 into the cavity 9. Shells 2, 3 at this time increase the volume of the cavity 9. A depression occurs in the cavity 9. Vapors leave the mixed components and partially fill the cavity 9. After that, the rotation of the drums is reversed. Shell 2, 3 reduce the volume of the cavity 9, moving towards each other. In the cavity 10 of the shell 2, 3 move in opposite directions. The volume of the cavity 10 increases and rarefaction occurs in it. At this time, serve a new portion of the mixed components. In the cavity 9 of the shell 2, 3 diverge. There is a vacuum in it. The pairs again fill the cavity 9. When the shells 2, 3 approach each other in the cavities 10, 9, the pairs are forced out into the condensate collection system 15. After 10 cycles, the valve 12 is opened and through it into the system 13 serves the finished mixture.

The use of the invention allows the mixing of components with high humidity and greater performance.
