Vertical dryer

Vertical dryer

working principle
The rotary dryer adopts the sleeve structure, so that the length of the dryer can be doubled, and the heat dissipation is greatly reduced due to the large reduction of the heat dissipation surface, and the doubled heat exchange surface greatly improves the thermal efficiency. For materials that cannot touch smoke, the multi-cylinder rotary dryer provides inner and annular smoke pipes in the inner and outer cylinders, respectively, and radial flues are used to communicate with each other, which is also highly efficient and energy-saving. It is not difficult to see that for hot material and cold medium, this machine becomes a sleeve-type rotary cooler.
3 Features
1. High degree of mechanization, large production capacity, and continuous operation.
2. The structure is excellent, simple, the material runs smoothly through the resistance of the cylinder, and the operation is convenient.
3. Fewer failures, low maintenance costs, and low power consumption.
4. Wide application range and good drying uniformity.
4 Structure
The rotary dryer can be designed with gas generator, combustion chamber or supporting hoist, belt conveyor, quantitative feeder, cyclone dust collector, induced draft fan, etc. according to user needs.
The main part is mainly composed of cylinder, front roller, rear roller, gear, blocking roller; drag roller, pinion, discharging part, lifting plate, reducer, motor, hot air duct, feeding chute, furnace body and other parts composition.
5 Patent sovereign items
The rotary dryer is composed of two to five coaxial sets of cylinders, which are connected to each other through radial supports (7) and (25), etc. The gear or other transmission system of the machine body receives external force to make the machine body rotate, and the material (20) is conveyed and lifted by the spiral blades in each cylinder and the intermittent screw lifting plate, and is lowered by the lower end of the collecting box (8) connected with the outer cylinder. The hot gas (21) can be mixed with the material (20), and discharged from the upper end of the collecting box (8), or by the inner smoke pipe (29), the annular smoke pipe (31) and the outer smoke hood ( 33) and the radial smoke pipes (30), (32) that communicate with each smoke pipe are discharged through the smoke exhaust port (34), characterized in that: (1) inner and outer cylinders (1), (2), (22) ) coaxial sleeves, which are integrated by radial supports (6) and (28), and are placed on the supporting roller groups (16) and (17). (6) and (24) and the intermittently rotating material plates (3), (4) and (23), (3) there is a hot smoke pipe (29) in the inner cylinder (1), and there is an annular smoke pipe between the cylinders (31), the outer layer of Z is provided with an outer smoke cover (33) and its smoke outlet (34), and radial smoke pipes (30) and (32) communicate between (29), (31) and (33).
