FIG. one

The invention relates to the mechanization of agricultural production and can be used to create high-performance dryers for flax and rough feed pressed into rolls.

The purpose of the invention is the intensification of the drying process, ensuring the uniformity of supposes of rolls and the expansion of technological capabilities.

.1 shows the dryer, a cross-section; FIG. 2 shows the trolley in its extended position for loading and unloading rolls; in Fig „3 - the dryer, view in plan, at the time of drying and simultaneous loading (unloading) of the rolls; figure 4 - section aa on figure 2; figure 5 - the relative position of the roll, removable arc-shaped emphasis, elastic sleeve connected to the duct through an adjustable damper.

The dryer for rolls of agricultural crops (Figures 1-5) contains several stationary trolleys 1 located in a drying chamber 2, which is a tightly closed room in which the furnace unit 3 (heat source) is installed and centrifugal fans 4 are installed on the air collection channel 5 and connected to it via recirculation tees, 6.

Each mobile trolley 1 is made of two fair-haired ones and has on each floor decks 7, in which there are two rows of equally spaced holes 8 with a size smaller than the diameter of the roll. Over each series of these openings, air ducts 9 are placed on which elastic sleeves 10 are fixed, through adjustable flaps 11 located coaxially with openings 8. Each elastic sleeve 10 has in its lower part a sealing ring 12 fixed on it , somewhat larger roll diameter. Each ring 12 is fixed at several points on the lifting frame 13, which is lifted by means of a lifting mechanism 14. The ducts 9, which are located one above the other, are connected with docking devices 15 with their output ends. Each nest formed by the floor 7 and the holes 8 is for precise installation rolls provided with a removable arcuate stop 16.

Along the ends of the trolleys there are sealing shields 17, the overlapping hermetically openings through which the trolleys 1 roll out along the rails to the outside by means of an actuator 18 having a gearbox with a drive sprocket that is permanently engaged with the chain underneath the trolley. An additional heat source during daylight can be a solar collector 19 located on the roof of a building.

The dryer works as follows.

Turning on the actuator 18, push any trolley 1 out. Then the lifting mechanism 14 through the frame .13 lift all the sleeves 10 with the rings 12 to the extreme upper position. Raw coil-. The PF-0.5 loader with the device 20 for grabbing the rolls is transferred from the vehicles to the trolley. 1, placing them vertically on the holes 8 and against the stops 16. At the end of this operation, the frame 13 is lowered with the rings 12 and the elastic sleeves 10, which are put on the rolls. After that, the drive 18 is turned on, and the trolley on the rails enters the drying chamber 2 and is connected to two vents. 4, namely, with their suction nozzles by means of docking devices 15. In this case, the right ushtotitelny shield 17 (Fig. 1) tightly closes the opening, it also serves as a trolley travel stop. Further, the second trolley 1 is pushed under the loading of rolls, which, being in the extreme right position, tightly closes the opening with its left shaft 17 (Figures 2, 3).

While the second trolley is loading rolls, you can roll the rolls first. Dp of this include two fans 4, which cool the coolant received from the furnace unit 3 and forced by it into the area of the rolls through the coils. The amount of heat carrier drawn through each roll can be adjusted with the help of Aslonok 11, depending on their humidity, density and distance from the fan, which allows all rolls to be uniformly dried and to significantly save heat.

The elastic sleeves 10, when the fans 4 are operating, fit the entire cylindrical surface of the rolls tightly and also press their lower

part of neither

to floorings 7 due to the vacuum created by the fans. As a result, the heat carrier from the drying chamber 2 can get into the air ducts 9, only passing through the rolls in their axial direction, and the intensity of the drying of the rolls increases. During the drying of the rolls on the first trolley 1, the same operations are performed with the second trolley loading it , inlet, docking and also with the following trolleys, if any.

The presence in the system of the connection of fans 4 to the air collecting channel 5 of the recirculation tees 6 makes it possible to block the access of the heat transfer medium to the channel 5 completely, when loading (unloading) the rolls to the corresponding car 1, through its idle fans 4.

Thus, the drying process of the rolls can be carried out almost continuously, with the exception of an extremely short time (a few seconds) for the extension and rolling of the trolleys for loading (unloading) the rolls.

To control the drying process, moist air sensors are installed in the suction inlet of fans. Recirculation of heat carrier in the dryer is carried out depending on the humidity of the air entering the fans 4. When the relative air humidity is low, a part of it is guided by tees 6 back to the siphonic chamber 2 for reuse.

The air entering the chamber camera 2, the passage through the solar collector 19 is heated. The use of a collector will allow you to save up to 30% of fuel, especially during the preparation of feed, when cyimy can only be brought about by heat from the solar collector,

B. The result of the fact that the air distribution system size; en. on trolleys so that each row of rolls located vertically has its own air duct connected to elastic sleeves by means of adjustable dampers, and the outlet ends of air ducts are connected to docking devices which, in the working position, are hermetically connected to fans, are substantially

the drying process is intensified, uniform drying is provided over all rolls, and the technological capabilities of the tanks are expanded, which means that it can be used even with incomplete loading (by blocking part of the dampers) in the event of a shortage of rolls.

Due to the fact that each nest for installing a roll is equipped with an adjustable arcuate stop, and the stop can be removable, the reliability in operation is greatly improved, since each roll occupies a position assigned to it, i.e. coaxial with the sealing ring and the elastic sleeve, which makes it easy to put the sleeves on the rolls and save time. In the absence of an emphasis, the tractor driver, as a rule, does not fall on the center of the nest with a roll, therefore, he is forced to move off and start again. to maneuver, and it reduces productivity when loading.
