Description

The invention relates to the field of cleaning and sorting of grain and can be used in agricultural production and grain processing industry.

A known machine for cleaning and sorting grain (ZVS-20).

The disadvantage of this machine is the insufficiently high quality of cleaning. The closest in technical essence (prototype) is an air-sieve separator A1-BIS-12 (Technological equipment for grain storage and processing / Edited by A.Ya. Sokolov: Textbook. - M .: KOLOS, 1984. - C .93-95), containing the receiving device, sieve and pneumatic separation modules.

The disadvantage of this air-sieve separator is the low quality of grain cleaning.

The aim of the invention is to increase the efficiency of grain cleaning and the implementation of fractionation of the grain mixture.

This goal is achieved by the fact that the known pneumatic sieve separator, including the receiving device, sieve and pneumatic separation modules, is equipped with a heap cleaner module and a fractionator module, the sieve of the sieve module and the sieve of the fractionator module are installed with opposite slopes and the end of the lower sieve module is connected with the beginning of the upper and lower sieves of the fractionator module with a pneumatic separating channel. The drawing shows a diagram of the proposed device.

The air-sieve separator-fractionator includes a heap-cleaning module 1, a trellis module 2, a pneumatic separating module 3, a fractionating module 4 and a dust separator module 5 connected to each other in a single structure.

The module-heap cleaner 1 has a receiving device 6, an air channel 7, a diametrical fan 8 and a sedimentary chamber 9, in which the air flow moves in a closed loop. To remove light impurities and dust from the sedimentation chamber 9, nozzles 10 and 11, respectively, are provided. The heap cleaner module also includes a through sieve 12 and a brush mechanism 13 for removing coarse impurities from the grain mixture, which are led out through the channel 14.

The sieve module 2 consists of a passage 15 and sieving 16 sieves and trays 17 and 18 for outputting large and small impurities, respectively. The sowing sieve 16 in the lower part has a tray 19 for supplying grain material to the air separation module 3.

The pneumatic separation module 3 includes a pneumatic separation channel 20, a diametrical fan 21, a sediment chamber 22 and an air supply channel 23 in which air moves in a closed loop. To withdraw light impurities from the sedimentation chamber 22, a pipe 24 is provided. At the bottom of the air separation channel 20 there is a window 25 for supplying grain material to the fractionator module 4.

The fractionator module 4 consists of a divider tray 26, two sowing sieves 27, 28 with trays 29, 30 for outputting the food fraction and a discharge window 31 for outputting the cleaned seed.

The through-sieve 12 of the heap cleaner module 1, the sieve module 2 and the fractionator module 4 perform circular oscillations on the suspensions 32 using the drive mechanism 33.

Cleaning the sieves of the separator-fractionator - ball.

The removal of light impurities and dust from sedimentary chambers 9 and 22 is carried out through nozzles 10, 11, 24 with a dust separator module 5.

The dust separator module 5 includes a fan 34 and a cyclone 35 connected in series with a discharge device 36.

The air-sieve separator-fractionator works as follows: the grain material (grain heap) is fed through the grain pipe to the receiving device 6 of the air cleaner module 1, which distributes it uniformly in width and feeds it into the air channel 7, where light impurities and dust are extracted from it which are deposited in the sedimentation chamber 9. Next, the grain material is fed to the passage sieve 12, where large impurities are removed from it, which are transported by a brush mechanism 13 into the channel 14 and brought out. The grain material preliminarily cleaned by the heap cleaning module 1 enters the sieve module 2, where large and small impurities are separated from it through the passage 15 and sieving 16 sieves, which are removed from the separator through trays 17 and 18, respectively. Then the grain material is left the sowing sieve 16 through the tray 19 it is fed into the air separation channel 20 of the air separation module 3, where light impurities are removed from it by the air flow created by the diametrical fan 21, which are deposited in the sedimentation chamber 22 and They are removed from the separator through the pipe 24. Then the grain material is fed to the fractionator module 4, where on the divider tray it is divided into 2 parts, each of which is fed to the sieving sieves 27, 28, where the food fraction is separated from it, which is divided into trays 29, 30 is discharged from the separator. The descent from the sieves 27, 28 - the cleaned seed grain is removed from the separator through the discharge window 31. Light impurities and dust through the nozzles 10; eleven; 24 sedimentary chambers 9 and 22 due to the vacuum created by the fan 34 are transported to the cyclone 35 of the dust separator module 5, where they are separated from the air and out through the discharge device 36.

Essence: the device includes a heap cleaner module 1, a sieve module 2, a pneumatic separating module 3, a fractionator module 4 and a dust separator module 5 connected to each other in a single structure.

The lattice 15, 16 of the sieve module and the lattice 27; 28 fractionator modules 4 are installed with opposite slopes and the end of the lower (subseeding) sieve 16 of the sieve module 2 is connected with the beginning of the upper 27 and lower 28 sieve module-fractionator with a pneumatic separating channel 20.

The invention will allow for one pass through an air-sieve separator-fractionator to receive seeds of class II-III from a grain pile and to separate a food fraction from it. In addition, due to the movement of air flows in the heap cleaner module and pneumatic separation module in a closed cycle, energy consumption for the cleaning process will be reduced by 30%.
