Description
【Technical field】
The utility model belongs to Non-ferrous Metallurgy equipment technical field, especially a kind of built-in miberal powder of electrical heating rotary furnace
Retracting device.
【Background technology】
For high-quality tungsten concentrate is for the tungsten metallurgical technology of raw material and need not set pretreatment process, and some are more complicated
Raw material was pre-processed before apportioned effort is entered and is very beneficial for steady production.
Pretreatment can remove the floating agent remained in complicated raw material, make the oxidations of impurities such as sulphur, arsenic into volatile oxidn
And be removed, to change the physical arrangement of complicated raw material, the leaching rate of tungsten and the purpose of reduction impurity are improved so as to reach.
The roasting of electrical heating rotary furnace is the one of which equipment of pretreatment, and electrical heating rotary furnace is by the hot-air in boiler tube
Dust collecting system is evacuated to by blower fan by airduct, the dust taken away with hot-air is because Action of Gravity Field is settled down to blanking in airduct
Pipe, is reclaimed by artificial per tour to material, there is dust from flying, loss of material greatly, and labor strength is big, be there is design and is lacked
Fall into.
【The content of the invention】
To solve the above problems, the utility model devises a kind of retracting device of the built-in miberal powder of electrical heating rotary furnace, leads to
Cross and install mineral fine recovering device additional in the middle of feed auger and rotary furnace hot air outlet, the miberal powder for settling down can directly be gone to
In rotary furnace, the purpose for reducing loss of material, reducing operator's labour intensity, improve working environment is realized.
For achieving the above object, the utility model is adopted the following technical scheme that：
A kind of retracting device of the built-in miberal powder of electrical heating rotary furnace, the electrical heating rotary furnace contain feed bin, feed auger,
Motor, airduct, end socket, boiler tube, tremie pipe and air port, motor drive one end of feed auger, feed auger to enter through end socket
In boiler tube, the other end connection feed bin of feed auger couples tremie pipe, boiler tube in the upper end connection airduct of end socket in its lower end
Stretch into the openend diameter in end socket and be given as D, the openend forms hot-air channel, and the air port of airduct lower end is less than described
The upper port of openend；The retracting device includes lower baffle plate, flange and overhead gage, it is characterized in that：
Flange is connected in the inner side of the openend, the internal diameter of the external diameter less than or equal to boiler tube of flange, the internal diameter of flange
Less than D, rectangular-shaped overhead gage is coupled in the internal diameter upper end of flange, rectangular-shaped overhead gage has upper vertical plate and upper level
Plate, the upper level board is concordant with air port and is connected in head lining end but can not block air port, straight in the lower end connection of flange
The lower baffle plate of horn shape, rectangular-shaped lower baffle plate has lower vertical plate and lower horizontal board, and the lower horizontal board is connected in head lining
End.
As a result of technical scheme as described above, the utility model produces following good effect：
1st, the utility model installs retracting device additional by the openend in boiler tube, and the most of miberal powder that settled down can fall
Enter in boiler tube, reduce the loss of miberal powder, improve the miberal powder rate of recovery, reduce the labour intensity of operator, improve working environment, it is right
Operator's is healthy highly beneficial.
2nd, its simple structure of retracting device of the present utility model, easy to make, and the body junction of electrical heating rotary furnace is not changed
Structure, only a small amount of miberal powder is fallen into the cloth bag of tremie pipe with hot-air from gap after installing retracting device additional, and about 2 are only needed after tested
Cleaning in individual month is once.

【Specific embodiment】
The utility model is a kind of retracting device of the built-in miberal powder of electrical heating rotary furnace, installs retracting device additional and has no effect on electricity
The agent structure of heating rotary stove.
With reference to Fig. 1, the agent structure of electrical heating rotary furnace mainly contains feed bin 1, feed auger 2, motor 3, airduct 4, envelope
First 5, boiler tube 6, tremie pipe 8 and air port 12, motor 3 drive feed auger 2, and one end of feed auger 2 enters boiler tube through end socket 5
In 6, the other end connection feed bin 1 of feed auger 2 couples tremie pipe 8, stove in the upper end connection airduct 4 of end socket 5 in its lower end
The openend diameter that pipe 6 is stretched into end socket 5 is given as D, and the openend forms the passage of hot-air 13, the air port of the lower end of airduct 4
