Description

 The invention relates to the processing of solid dispersed substances by a liquid, in particular, apparatuses for carrying out leaching, washing, dissolving upon contact of a liquid and solid granular material.

A known apparatus for treating solids with liquid, containing a vertical cylindrical body, contact plates in the form of inverted truncated cones located along the height of the body, reflective conical elements fixed between the smaller bases of the cones and reflective elements, perforated distribution rings, as well as fittings for input and output phases [ 1]
The disadvantages of this apparatus are the complexity and cumbersome design of sectioning elements. In addition, cones with reflectors occupy a large part of the body, reducing the useful (working) volume of the camera.

A known apparatus for treating granular material with a fluid, comprising a cylindrical body with nozzles for supplying and discharging the current medium and a nozzle for supplying bulk material and an airlift pipe for unloading, as well as perforated grids located in the housing, fixed in the shell, in which the slots are made [ 2]
The disadvantages of this apparatus are the complexity of its manufacture, due to the need to perform high precision elements, erosive wear of metal parts in contact with reagents, the small working volume of the case due to the cumbersomeness of its internal equipment, as well as insufficiently effective processing of the material.

The closest in technical essence and the achieved effect to the proposed one is a fluid processing apparatus for granular material, comprising a housing, a perforated shell mounted coaxially to the housing, nozzles for supplying and outputting granular material located between the perforated shell and the housing. In the center of the apparatus, a mixing means for intensifying the contact between the liquid and the granular material [3]
The disadvantages of such an apparatus include the energy costs of driving the mixing means, a significant free volume of the apparatus occupied by the mixing device, erosive wear of the blades of the mixing device.

 The purpose of the invention is the simplification of design, increase productivity.

 This is achieved by the fact that in the device for processing granular material with a fluid containing a housing, a distribution system of a fluid, a loading and unloading system of granular material, a mixing means, the housing is equipped with nozzles of a smaller diameter, and a drive shaft is coaxially mounted inside the housing, on which the drive shaft is arranged in series reversible drums. Sleeves are wound on the drums in opposite directions, the ends of which are turned out and fixed in the corresponding nozzles. The sleeves form cavities in communication with the distribution systems of the granular material and fluid. The body cavity is filled with a working agent.

 The drawing shows the proposed device, General view.

 It has a housing 1, equipped with nozzles 2, 3. A shaft 4 with a drive 5 passes through the housing 1. Reversible drums 6, 7 are installed on the shaft 4, on which sleeves 8 and 9 are wound in opposite directions. The free ends of the sleeves 8 and 9 are turned out and fixed respectively in the nozzles 2 and 3 with the formation of cavities 10. The sleeves 8 and 9 form in the nozzles 2 and 3 cavities 11 and 12, which are in communication with the systems 13, 14 for unloading the finished granular material, with systems 15 and 16 for supplying and discharging liquid, respectively with system 17 loading granular matter a. The body cavity is filled with a fluid agent.

 The device operates as follows.

 The system 17 serves the granular material in the cavity 12 with the simultaneous supply of fluid by the system 15. The drums 6, 7 rotate to the left. The sleeve 9 enters the pipe 3 and displaces the liquid into the system 16, and the granular material into the system 14.

 Then the drums 6 and 7 are rotated in the opposite direction. The sleeve 9 is wound on the drum 7, the sleeve 8 enters the pipe 2, forcing the granular material into the system 13, and the liquid into the system 16.

 The use of the invention allows to increase the productivity of the device, reduce material consumption and energy consumption, simplify the manufacture and operation of the device.
