A disadvantage of the known device is the uneven removal of moist air generated by the evaporation of moisture from the dried material throughout the chamber.

The objective of the proposed utility model is to reduce energy consumption and improve the quality of the finished material due to the uniform removal of moist air throughout the chamber.

The problem is achieved in that in the installation for drying bulk materials containing a chamber, with a conveyor placed therein to move the processed material, above which are located blocks of infrared emitters with reflectors, material loading and unloading devices and a fan, the camera is equipped with a new one an exhaust manifold of triangular section, rigidly connected to its side wall, in which a slotted hole is made along the length of the chamber, and through a gas duct consisting of two inlet and one outlet branch pipe and a common collector, connected to a fan, while in the device for loading material in the form of a storage hopper, rigidly mounted on supports, in its lower part there is a belt feeder above the conveyor inlet, and a device for unloading material in the form of a transfer hopper under estrus, pivotally connected to the camera at the outlet, and the conveyor belt for moving the processed material is made of heat-resistant material with a Teflon coating.

An exhaust manifold made of a triangular cross-section ensures alignment of the velocity field at the inlet along its entire length, which leads to uniform suction of air from the chamber.

The slit hole made along the entire length of the chamber helps to remove moist air throughout the entire volume of the drying chamber.

The flue, made in the form of a common collector with two inlet and one outlet pipe increases the number of suction points and the uniformity of the removal of moist air from the chamber.

The belt feeder is used to provide an accurate dosage of the supply of material for drying and the required performance.

The implementation of the conveyor belt of heat-resistant material, due to exposure to high temperature from infrared heaters increases its operational characteristics.

The proposed installation for drying bulk materials is illustrated by drawings where:

figure 1 shows a General view of the installation;

figure 2 cross section along aa installation

The apparatus for drying bulk materials contains a chamber 1, a conveyor 2 located in it for moving the processed material, over which there are blocks 3 of infrared emitters with reflectors 4, an exhaust manifold of triangular section mounted rigidly to its side wall 5, in which is made a slit hole 6 along the entire length of the chamber 1, through a gas duct consisting of two outlet 7 and one inlet 8 nozzles and a common manifold 9, is connected to a fan 10, a device for loading material in the form of a hopper accumulator 11 which is rigidly mounted on supports 12, and in its lower part is mounted tape feeder 13 on the input portion of the conveyor 2, for discharging the material dispensing device in the form of the hopper 14 is disposed under the estrus 15 pivotally connected to the chamber 1 on the output. The tape 16 of the conveyor 2 is made with a Teflon coating.

Installation for drying bulk materials works as follows.

The required amount of dried material is poured into the storage hopper 11, then using a tape feeder 13 the material is fed with a certain dosage to the inlet section of the chamber, in which it moves along the conveyor 2 along the chamber 1 with a given speed that determines the performance of the installation. Blocks of infrared emitters 3 with reflectors 4 are installed on the upper wall of the chamber, with the help of which the material is heated directly to remove moisture. Reflectors 4 serve to enhance the heating effect on the material by reflecting infrared rays from the heaters towards the material. Along the entire length of chamber 1, a local moist air suction is organized using a fan 10, a gas duct consisting of 2 inlet pipes 7, one outlet pipe 8 and a common manifold 9, rigidly fixed to

side wall of the camera. The material is unloaded using estrus 15 into the dispensing hopper 14, intended for further storage and transportation of the dried material.

The technical result of using the installation for drying bulk materials is to reduce energy consumption by 13-15% relative to the prototype per unit of production and improve quality by 15-20% due to the uniform removal of moist air throughout the chamber.
