INSTALLATION FOR TERESDESINSECTION OF GRAIN

The proposed utility model relates to a system of harvesting, storage and processing of grain, namely, devices for processing grain infested by insects.

A known installation for thermal disinsection of grain, comprising a device for producing a high-temperature flow of a gas-based mixture (drying agent), a shaft-type drying chamber, grain containers and transporting mechanisms.

The disadvantage of these devices is that they do not provide effective pest control, because the large unevenness of grain heating in shaft dryers (average temperature fluctuation reaches 10 -) leads to the fact that with average heating of the grain to acceptable temperature limits () part of the grain due to overheating may lose its food value, in another part due to overheating it may not be complete pest deaths achieved

Na1 closer to the proposed utility model in terms of technical nature and the achieved result is a plant for thermal disinsection of grain.

The known installation comprises a device for producing a high-temperature flow of a gas-air mixture, a pneumatic pipe connected to it with a device for loading grain, and a sedimentation chamber connected to the discharge section of the pneumatic pipe.

Щ) And this device for receiving a high-temperature gas-air mixture contains a coal furnace and a high-pressure fan connected to the sedimentation chamber by an air duct, and the pneumatic tube is made vertical.

A disadvantage of the known installation is the need for network electricity, in addition, the installation is not environmentally friendly enough and disinfected grain is released near the infected grain loading point (due to the use of an upward and downward flow of the air-gas mixture), which can lead to live pests entering the disinfected grain.

The utility model is based on the solution of the problem aimed at creating a new energy-autonomous installation for thermo-disinsection of grain, allowing me to disinfect the grain while transporting it to a distance of 40 meters.

Moreover, the use of the proposed utility model allows

improve the environment through more complete combustion of fuel.

To solve the problem in the proposed installation for thermal disinsection of grain, containing a device for producing a high-temperature flow of a gas-air mixture, connected with it air / - - / dg

a pipe with a device for loading grain and a sedimentary chamber connected to the outlet section of the pneumatic pipe, the difference is that the device for receiving a high-temperature flow of the gas-air mixture includes a combustion chamber with a working nozzle and an air blower, a pneumatic pipe is coaxial with the working nozzle and connected to it , the device for loading grain is made in the form of an elevator, the confuser of the azector is turned towards the working nozzle of the combustion chamber, and the diffuser) toward the sedimentary chamber.

The difference is that the pneumatic tube is made telescopic. The specified installation allows you to achieve energy autonomy, to create a more convenient installation, more environmentally friendly and compact.

The vulcanization of the telescopic pneumatic tube allows to reduce the duration of preparation of the installation for work, as well as to achieve compact installation in transportable positions.

The implementation of a device for loading grain in the form of an ejector is necessary to eliminate the losses of the gas-air mixture at the injection site

pneumatic tube of grain, as well as uninterrupted supply of grain to the installation, FIG. 1 shows the proposed installation for thermal disinfestation

grains;

In FIG. 2 - a device for producing a high-temperature flow of a gas-air mixture.

The installation comprises a device 1 for producing a high-temperature flow of a gas-air mixture, a pneumotube 2 with a device 3 for loading grain, and a sedimentation chamber 4 with a cargo valve 5.

A device 1 for producing a high-temperature gas-air mixture stream comprises a combustion chamber b. Luggage Gorania equipped

-I

a benvin tank 7 connected to it through a filter sump 8, a tee 9, a compensator 10, a gas atomizer 11, a valve 12 and a burner cone 13 by means of a gas line 14. To supply air to the chamber 6, there is a two-rotor air blower 15 equipped with a filter 16. For messages of rotation to the rotors of the air blower 15 have an internal combustion engine (for example, UD-2, not shown in the drawing), the combustion chamber 6 is equipped with a working nozzle 17 connected to the pneumatic tube 2 coaxially located with it, and also a spark plug 18. The device 3 D.P.Y. of grain loading is made in the form of an ejector; in this case, confuser 19 of section 3 is directed towards the working nozzle 17 of the combustion chamber 6, and the diffuser 20 is directed towards the sedimentary clasher 4.

Installing works as follows.

In the combustion chamber 6 of the device 1 to obtain a high-temperature flow of gas-gas mixture, liquid hydrocarbon fuel, for example gasoline, kerosene, atomized by air, ignited from the spark plug 18, is supplied. A mixture of hot gases and air with a temperature of 500 - and with a speed of 250 - 300 m / s through the working nozzle 17 enters the pneumotube 2, into which at the distance of 800 - 1000 mm from the nozzle 17 the grain is introduced, infected with insects (for example barn weevil) in the amount of 3-7 t / h. The grain is picked up by a high-temperature flow of a gas-gas mixture and, transported through a pneumatic pipe 2 to the required distance (15 - 40 m) for 2 - 3 s, it is heated to a temperature of 60 - and disinfected by underlining. Then, getting into the sedimentation chamber 4, the grain is separated from the gas mixture and through the cargo valve 5 is removed from the installation.

Obtaining a high temperature flow of the gas-air mixture is as follows.

- Atmospheric air sucked in by the air blower 15 enters the cone 13 of the burner. There, gasoline is supplied from a tank 7, which passes through a filter sump 8, a tee 9, a compensator 10 through a gas line 14 and is sprayed using a spray gun 11. Sprayed gasoline ignites from the candle 18 valsigany, burning with excess air in the combustion chamber b. Hot gases exit the combustion chamber 6 through the working nozzle 17. A portion of the gas from the tee 9 goes to the operation of the internal combustion engine.

The use of the claimed utility model in comparison with the prototype allows you to:

-to achieve energy autonomy through the use of device 1 to obtain a high-temperature flow of a gas-air mixture of the proposed design that does not require electricity;

-to increase the environmental friendliness of the installation due to more complete combustion of fuel;

-Create an installation more compact and convenient to use.
