Description

The fire-drying grain dryers moving on wheels are well known, as well as the use of trolleys in them on which the material being dried is laid, heated by hot air, directed through the tube from bottom to top and removed through the chimney. In the proposed mobile grain dryer, the air-heating chamber in the heater is located above its fire chamber and is made two-fold by dividing it with horizontal baffles, rods, causing air to travel along a zigzag path.

In FIG. 1 shows a longitudinal section of a grain dryer; FIG. 2 - the same, transverse cut; FIG. 3 is the same, top view; FIG. 4 is a top view of the roof of the dryer.

The lower part of the frame with the firebox of the dryer (fig. 1-3) is made of channels, squares and boiler sheets of different thickness, and in the middle in the middle are two combustion chambers / from which the gas ducts go 2. Between these channels, from below, above and laterally closed with iron, open rib batteries are placed, indicated by a dotted line in the drawing. Four axles are attached to the bottom of the frame, on which four wheels rotate to transport the firebox to its intended purpose. All other parts of the dryer, like its walls, are medium and

the top frame, as well as the roof, are assembled.

Above the fire chamber 7, an air-heating chamber 5-4 is placed for hot air; it is made double-layered by dividing by horizontal partitions 9 and 10, causing the heated air to go along a zigzag path. Between the flooring and the overlap, the hot air passes into the vents and above again into the space; Above this space, an average frame is made with laid wooden planks in the form of rails, on which the first Russian of 8-four trolleys is installed in four rows and two rows in length (there are only eight trolleys in one Rus). Above the trolleys there is a space 5, and then the same frame with wooden bars for the second floor of the trolleys.

Above, there is a space 6, which rises to a cone in the pipe to exit the hot gas and evaporate the crude product. Over this space there is an overlap, and over the overlap is a roof 7 with a slope; between the ceiling and the roof 7 pass channels with hot gases passing into the pipe.

Iron brackets are bolted to the lower frame at the corners and in the middle of the walls, and the middle brackets are attached to these brackets. The side walls are made double, the inner walls are made of thin

sheet iron, while the exterior is made of light wood or plywood; empty space is left between the walls.

The front wall and the rear walls are solid; in the rear wall there are also channels for the passage of hot gas upward, and the front wall is made of two parts (outer and inner) with a small space between them; The side walls are also made of two halves and hinged, and they can be opened for passage through the dryer of the trolleys during their loading or unloading; after the material is dried, the trolleys move to the thresher also along the rails.

Each trolley has a door on one side for the quickest unloading of sheaves to the machine; in each such wago, netka you can put three stacks of sheaves,

A total of sixteen trolleys are placed in the dryer.

The subject matter of the invention.

Mobile dryer using hot air heated air heaters placed in the lower part of the drying chamber, equipped with a number of compartments loaded with trolleys with dried material, and passing through the cavities in the walls of the chamber of hot gases sent into the pipe together with the exhaust in the chamber air, characterized in that the air-heating chamber 3 - 4 in the heater is located above its fire chamber 7 and is made two-fold by dividing by horizontal partitions 9 and JO, forcing Draw air through a zigzag path.
