Description

The invention relates to the primary processing of cotton and can be used for the chemical-mechanical delintering of cotton seeds.

The purpose of the invention is to increase the processing efficiency.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. ; in fig. 3 section n FIG. one; in fig. 4 - node 1 ,.

The device contains a horizontal-sided camera 1 with a cylindrical bottom 2, inlet and outlet for CEM, and 3 and 4 holes and nozzles 5 and 6 for introducing a chemical agent, a seed mixing assembly in the form of a screw 7 with strips 8 and a screw-shaped curved strip 9, mounted on the outer surface of the screw screw auger. For feeding the seeds, there is a storage bin 10 with a diaphragm 11 forming the inlet 3, and a segment 12 is installed in the area of the outlet 4.

The device works as follows.

The seeds are fed into the neck of the storage hopper 10 and through the hole 3 in the diaphragm 11 with the help of screw 7 are transported to the working chamber 1 in a strictly metered quantity, where they are subjected to chemical treatment with vigorous stirring by means of fixed on. a screw of strips 8 and a screw strip 9. Since: the mixing bars 8 are outside the zone of operation of the auger transport blade and there is a segment 12 in the path of the seed, the seeds move in the working chamber evenly and at a constant filling ratio.

The opening 4 enters the next similar chamber where treatment with another reagent is performed.

The diameter of the transporting auger is 1/3 - 2/3 of the diameter of the cylindrical bottom 2 of the chamber, and the diameter of the bottom is chosen in accordance with a given processing exposure, and the diameter of the screw corresponds to a given performance of the device. Reducing the screw diameter reduces the force of friction of its surface against the seeds, and also allows treatment at a higher frequency of rotation, i.e. with more intensive mixing.

The presence on the outer surface of the screw blade of the screw screw-shaped strip protruding on both sides of the boat at an equal distance creates additional mixing of the seeds within the screw diameter like a drum mixer: and contributes to the leveling of the seeds in the chamber.

A mixing plate is installed in the gap between the strip and the bottom of the chamber, i.e. outside the limits of the transport auger, which ensures uniform and metered movement of seeds.

The installation in the storage hopper of an aperture with a hole concentric on the screw surface ensures a constant accumulation of seeds in front of the working chamber and thereby isolating the working chamber from the atmosphere, as well as the metered flow of seeds into the chamber at a constant frequency of rotation of the auger shaft.

A segment with a hole — a larger screw diameter is mounted at the exit from the chamber, which ensures the constant filling ratio of the working chamber.

DEVICE FOR TREATMENT OF COTTON SEEDS, containing a horizontal chamber with a cylindrical bottom, openings and outlets for seeds for the input of the processing chemical reagent, and a seed mixing unit in the form of a screw mounted along the chamber axis with planks mounted on it parallel to the axis, which is different that, in order to improve the processing efficiency, the seed mixing unit is equipped with a means for leveling the seeds in the chamber in the form of a helically curved strip fixed to the outer surface the screw blade of the screw coaxially with it, wherein the strip is formed with a width exceeding the width of the blade, and the width is fixed symmetrically relative to the latter in a longitudinal section of the screw, and the strap disposed between the outer surface of the strip and the bottom of the chamber with a clearance relative to the latter. 1203139 ² hole 4 enter the next similar chamber) where processing by another reagent is performed. Conveyor screw diameter 5 is 1/3 - 2/3 of the diameter of the cylindrical bottom 2 of the chamber, and the diameter of the bottom is selected in accordance with a given exposure of processing, and the diameter of the screw corresponds to a given 10 of the productivity of the device. Reducing the diameter of the screw reduces the friction force of its surface on the seeds, and also allows processing at a higher frequency of its rotation, i.e. with more intensive stirring. The presence on the outer surface of the screw blade of the screw of the helical strip, protruding on both sides of the scallop for an equal distance, creates additional mixing of seeds within the diameter of the screw like a drum mixer; and helps level out 25 seeds in the chamber. The stirring bar is installed in the gap between the strip and the bottom of the chamber, i.e. outside the conveyor screw, which ensures uniform and metered movement of seeds. The installation of a diaphragm in the storage hopper with an aperture concentric to the auger surface ensures a constant accumulation of seeds in front of the working chamber and thereby isolates the working chamber from the atmosphere, as well as a metered seed supply in the chamber at a constant speed of the auger shaft. 40 ,, At the exit from the chamber, a segment with an aperture larger than the screw diameter is mounted, which ensures a constant filling factor of the working chamber.
