Description
Technical field
The invention belongs to mechanical field, and in particular to a kind of continuous rotary drying machine.
Background technology
In recent years, with the raising of energy prices and the cost of raw material, there is an urgent need to develop the new energy.Green,
The solar energy of safety non-pollution turns into one of emphasis of research, and polysilicon is the indispensable material for developing solar cell, therefore
The production of polysilicon and the raising of purity are as the emphasis studied.The meeting in the technique such as production and purification of current production of polysilicon
Produce and also have the solid slag slurry such as silicon tetrachloride, trichlorosilane and silicon dichloride and chloride.These materials easily with air and
Water reaction generation flammable and explosive substance, if untreated any discharge, necessarily pollutes the environment.
At present, more universal processing method is by dry means, chlorosilane is converted to gas and separates, and is done
Slag charge after dry is sent to subsequent technique, reduces hydrolysis process amount, while the chlorosilane gas separated can continue to convey
Lead in polycrystalline silicon reducing furnace and recycle, but traditional slurry drying machine uses intermittently operated, inventory of drying equipment
Greatly, the bearing capacity of equipment and thermic load are very high.
The content of the invention
It is an object of the invention to provide a kind of continuous rotary drying machine, the continuous rotary drying machine has simple in construction, energy
Continuous operation, the advantages of thermic load is relatively low.
To achieve the above object, the present invention adopts the following technical scheme that：
Continuous rotary drying machine of the present invention, including outer barrel, rotation cone cylinder, interior ribbon, feed pipe, drive shaft and motor,
Gas vent is provided with the upside of fuselage, is provided with waste outlet on the downside of outer barrel, setting star valve at waste outlet, interior ribbon be arranged on into
In expects pipe, and interior ribbon is installed along with rotation cone cylinder with feed pipe, and the left end of feed pipe passes through the left end of rotation cone cylinder
Stretch out afterwards outside outer barrel, rotation cone cylinder is arranged in outer barrel, and drive shaft is arranged on the side of outer barrel, and one end of drive shaft and rotation
The right-hand member of cone cylinder is connected, and the other end of drive shaft is connected with the output shaft of motor.
The invention difference from existing technology is：First, drying machine of the present invention uses nested double cone structure, material exists
By the heat exchange twice of rotation cone cylinder and cylindrical drum in drying machine；Second, feed pipe extend into the inside of drying machine, plus rotation
The presence of cone cylinder, the space in drying machine is divided into two parts, therefore stroke of the material in drying machine is two drying machines
Length, add the residence time of material.
As the improvement of the present invention, in addition to outer ribbon, outer ribbon is arranged in rotation cone cylinder.
Outer ribbon and rotation cone cylinder are hollow structure, interior logical steam, add the heat transfer area of unit volume.
As the improvement of the present invention, in addition to driving spindle nose, driving spindle nose is arranged on driving the tip of the axis, and drives spindle nose
It is connected with motor by chain.
As the improvement of the present invention, in addition to chain end cap, chain is arranged in chain end cap.
As the improvement of the present invention, in addition to leg, leg is arranged on the bottom of outer barrel.
This design is easy to steadily install outer barrel.
In summary, the beneficial effects of the invention are as follows：It is simple in construction, can operate continuously, good effect of heat exchange, thermic load compared with
It is low.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
