Description

The invention relates to agricultural machinery, in particular to devices for drying beet pulp.

A device for drying grain [Device for drying grain. - Patent RU 2323580. - Publ. 05/10/2008, Bull. No. 13], comprising a cylindrical casing, a loading hopper, an unloading window, a transporting working element coaxially mounted inside the casing for rotation, heating elements and a cooling device, which consists of a fan and an air duct connected to the internal cavity of the casing behind the unloading window. The outer surface of the casing is covered with a layer of heat-insulating material. The transporting working body is made in the form of a screw with perforated turns. The diameter of the perforation of the screw does not exceed the minimum grain size. The casing is made integral. The components of the casing are divided among themselves by rings, which are made of heat-insulating material. Heating elements are placed on the outer surface of the casing under a layer of heat-insulating material between the loading hopper and the unloading window with the possibility of individually controlling the heating temperature of each of the sections of the casing. Each component of the casing is equipped with an individual heating element. The end surface of the casing from the side of the hopper is perforated.

The known device has the disadvantage of low quality drying of beet pulp.

The technical result is an improvement in the quality of drying beet pulp.

The claimed technical result is achieved due to the fact that the casing is of rectangular cross-section. The transporting working body is performed in the form of an endless chain with shafts pivotally mounted on it. The shafts are made coaxial, and the distance between the shafts is taken not exceeding the minimum size of the transported product. Inside the casing, a box with holes in its upper part is installed. The upper branch of the chain with scrapers is carried out resting on the upper part of the box. An air duct is made in the side of the duct. The duct is connected to the box at an equal distance from the loading hopper and the discharge window and place heating elements and a fan in it.

In FIG. 1 shows a General view of the device; in FIG. 2 - section along aa.

The device for drying beet pulp consists of a casing of rectangular cross section 1, covered with a layer of heat-insulating material 2, a loading hopper 3, an unloading window 4 installed inside the casing of the transporting working body 5, heating elements 6, fan 7 and duct 8. The transporting working body 5 is made in in the form of an endless chain with coaxial shafts pivotally mounted on it 9. Inside the casing 1, a box 10 is installed with holes 11 in its upper part. The upper branch of the chain with the shafts rests on the upper part of the duct 10. The duct 8 is located on the side of the duct 10 at an equal distance from the loading hopper 3 and the discharge window 4. The heating elements 6 and the fan 7 are installed in the duct 8. The distance between the shafts 9 does not exceed the minimum the size of the transported product - beet pulp particles.

The device operates as follows. Turn on the heating elements 6 and the fan 7. Then turn on the drive (not shown) of the transporting working body 5. When the endless chain moves, the shafts 9 are in contact with the upper part of the box 10 and, due to friction forces, rotate around its axis in the direction of movement of the transporting working body 5. Then they feed the beet pulp into the loading hopper 3, from where it enters the rotating shafts 9. The distance between the shafts 9 does not exceed the minimum size of the product being transported, due to this the beet pulp does not fall down between they, and due to the rotation of the shafts 9 moves to the unloading window 4. Heated by the heating elements 6, the air flow through the duct 8 enters the box 10, where through holes 11 in its upper part passes between the shafts 9 and then through a layer of beet pulp moving along them . In this case, heated air heats both the shafts 9 and beet pulp, which, when in contact with heated air, also heats up, loses excess moisture. Excess moisture in the form of steam is removed from the device partially through the discharge window 4, and partially through the loading hopper 3. The beet pulp is also heated by contacting with heated and rotating shafts 9, which increases its drying efficiency. The finished product is removed from the device through the discharge window 4.

Improving the quality of drying beet pulp is achieved by making a rectangular casing and placing a transporting working body inside the casing, made in the form of an endless chain with articulated axial shafts, the distance between which does not exceed the minimum size of the transported product.

Due to this, and also due to the implementation of the upper branch of the chain with the shafts resting on the upper part of the box during movement of the transporting working body, the shafts come in contact with the upper part of the box and, due to friction forces, rotate around its axis in the direction of movement of the transporting working body, ensuring the movement of beet pulp without sticking on the transporting working body to the unloading window. The required temperature for heating the beet pulp is ensured by uniformly blowing heated air through the holes in the upper part of the box and moving the dried product at a predetermined speed by the upper branch of the chain of the transporting working body with the shafts to the discharge window. All this improves the drying quality of beet pulp. In turn, uniform airflow is ensured by connecting the duct to the duct at an equal distance from the loading hopper and the discharge window and installing heating elements and a fan in the duct.
