Description

I

The invention relates to aspiration seed buds and is intended for cleaning and sorting cotton seed.

A device is known for the installation of this type of suction using an aspiration method, which includes a housing, a loading device, at the exit of which blinds and a fan are installed.

The disadvantage of this device lies in the inefficient separation efficiency and the small number of isolated fractions.

The closest to the proposed technical essence and the achieved result is a device for separating bulk materials, including a housing, a loading device, a blower fan and receiving chambers of f2j separation products.

However, it is impossible to divide the seeds according to "{shares from the map by the deviations of the mass and standard sizes of the individual seeds and the impossibility of regulating the trajectory of the seeds.

The purpose of the invention is to increase the efficiency of the sorting process by equalizing the air flow along the length of the chamber.

This goal is achieved due to the fact that the device is equipped with control valves, located at the top of the chamber. and a suction blower mounted in line with the injection fan.

The figure schematically shows a general view of a device for sorting cotton seeds.

The device includes a housing 1, in the lower part of which the receivers of separation products 2 are located. The housing 1 is connected to the delivery fan 3 and the pipe 4, and on the other hand with the suction fan 5 and the pipe 6 above the pipe 4 in the delivery area Sem N 7, at the exit of which in the nozzle 4 are mounted louver shutters 8. Nozzles 4 and b

made of the same live section. In the upper part of the housing 1 there is an air chamber 9 with control valves 10 located above each receiving chamber 2. The air chamber 9 is connected by a pipeline 11c with a suction system. Adjustable partitions 12 are installed between the receiving chambers 2, and a system of flaps 13 is located in the lower part of the receiving chambers 13. The suction area of the fan 5 is connected to a horizontal cycle 14 to remove dusty air.

A device for sorting cotton seeds works as follows.

Seeds by the loading device 7 are fed into the injection zone after the louver flaps 8. Air is pumped by the fan 3 and, after passing through the louver dampers 8, which equalize the air velocity over the entire cross section of the housing, pick up the cotton seeds and move them in the direction of the fan suction zone 5. Due to the different Mass of seed sizes and their aerodynamic properties, the latter receive a different amount of movement, which leads to the fall and separation of seeds through the corresponding receiving chambers 2, divided The regulating baffles are 12. For finer separation of seeds with small deviations in mass and sizes, there are regulating dampers 10 that are connected to the chamber 9 connected to the suction system. This allows the necessary air suction over each chamber 2, which affects the trajectory of the seeds, increasing their flight path and allows the seeds to be divided into a large number of fractions.

Regulating dampers 1O are installed depending on the requirements for the seeds after sorting. From the receiving chambers 2, the seeds are extracted using a system of flaps 13. The dusty air from the chamber 9 and the suction zone is supplied to a horizontal cyclone 14 or independent cyclones, where it is cleaned of weed impurities.

The presence in the upper part of the body of the air chamber with regulating dampers above the receiving chambers allows the sorting of seeds with small deviations in mass and size, which increases the efficiency of the device.
