Description

To prepare concentrates from grits, it must be thoroughly rinsed to obtain high quality concentrates. The known types of batch washers do not satisfy the requirements for the flow of concentrate production.

The proposal relates to devices for washing cereals and similar products, which water is fed into the washing vessel from the bottom up and is intended to carry out a continuous washing process. For this, an additional vessel is used in the device, the lower part of which is connected to the lower part of the washing vessel. The continuous washing process is accomplished by loading the cereal into the main vessel of cBlepxy and shipping it through the top of the additional vessel. When this occurs, the countercurrent movement of cereals and water. Continuous shipment of washed cereals can be carried out with a jaw located in an additional vessel.

The schematic drawing shows an exemplary implementation of the proposed device iB longitudinal section.

The washing cylindrical vessel 1 is installed vertically and provided in the lower part with a false mesh inclined bottom 3 and a removable conical bottom 9, and in the upper part it has windows 4, an annular drainage chute with L; 0t: clod 7 and a hopper 5. The washing vessel 1 is reported in the lower part with an additional vessel 11, made in the form of a pipe. This vessel at the bottom, at the mouth of the communicating channel, is equipped with a screw 12, which receives rotation from the electric motor through a pair of conical jaws 19. At the top of the pipe I there is a nozzle 15 dl) for the exit of the washed grain entering the receiver or on the conveyor belt. The drive shaft of the screw is equipped with a crankshaft 18 for actuation, simultaneously with the operation of the screw, of the air pump 16. Air is pumped into the cylinder 17 equipped with a pressure gauge 20 and the oil drain valve 23. Inside the vessel 1, the false bottom is mounted (TURNER of rubber hose 2 or metal tube with openings and a rubber tube pulled into it. Pipe 2 is supplied with compressed air from a balloon 17 through pipe 21 and a crane 25. Punctures are made in the rubber hose or in the rubber tube for the passage of compressed air to automatically overlap elasticity re: tires. These punctures can be made by a cross piercer, which will give better results, since in this case each hole will have a four-valve, easily opened by the action of compressed air and closed by elastic rubber. Under the false bottom 3 it is attached chamber 8, to which the tube 22 is connected to the left side, communicating with the tube 21. Separately from the grits, when washing, the flour mass will pass through the false bottom net to the bottom 9; at the same time the grid is not excluded. The chamber 8 serves to receive compressed air and to clean the false bottom grid when it opens the valve 24. Compressed air simultaneously with the cleaning of the grid will push the flour mass on the bottom 9.

The operation of the device occurs & next order. In the pipe 11 and the vessel 1 through the water supply. 13 water flows. Towards flowing water through the hopper 5, the grits are supplied, which require rinsing. The valve 25 is opened for inflow into the compressed air vessel. The streams of air in the form of bubble, striving towards the grains descending due to the pressure and affecting them, keep them in a raised state until the moment when the grains leave the sphere of action of the air bubbles. Krupipki exposed to flowing water and air bubbles.

freed from contaminants, lowered under the influence of their weight and false bottom and slide along it into the passageway, from where they are traporped with a screw into pipe 11. When passing through pipe 11, grains are again subjected to washing with water coming through pipes 13 and (take it out through nozzle 15.

The light impurities that separate from the grains, such as slits, debris, etc., are carried by flowing water from vessel 1 through the window (and 4 is groove 6, and from the latter, in tray 7, into the mesh collection, in which freed from water.

The flour mass that descends through the holes of the false bottom grid enters the sloping chamber 8, from which, under the action of its weight, as well as by blowing with compressed air, it is removed to the bottom 9 of the vessel I and vvade outside through the valve 10. The flow of water as it consumes is regulated by the usual in the drawing not shown, automatically acting float valve. The same valve regulates the water level in the pipe I.
