Description
Technical field
The present invention relates to flash dryer field more particularly to a kind of admission gears for molybdenum concentrate flash dryer.
Background technique
It is in the prior art that the wet molybdenum that humidity is 12%~18% is first obtained in Molybdenum Mine to the production procedure of molybdenum ore resource
Then wet molybdenum powder is dried to the wet molybdenum powder that humidity is 6%~7%, then the wet molybdenum for being 6%~7% by humidity using gas heating by powder
Powder is sent into drying in flash dryer and obtains molybdenum concentrate, molybdenum concentrate is sent into calcining kiln after roasting and obtains molybdenum oxide finished product.On
It states in production procedure, needs to carry out drying to wet molybdenum powder first with combustion gas to be re-fed into flash dryer, a large amount of combustion will be consumed
The gas energy；And during being roasted to molybdenum concentrate, a large amount of high-temperature tail gas can be generated in calcining kiln, contain in high-temperature tail gas
The a large amount of waste heat energy, but in the prior art usually by high-temperature tail gas direct emission, above-mentioned two situations lead to existing molybdenum ore
The gas energy consumed in resource production is larger, and there are problems that waste heat energy waste.
Cause the reason of consuming a large amount of gas energies to have multiple, one of them be exactly in existing flash dryer hot gas it is equal
To flow directly into from cylinder body bottom, keep flow effect of the hot gas in cylinder lumen poor, it is difficult to it is higher to form circumferential gas velocity
Spiral gas field keeps hot gas poor to the drying effect of wet molybdenum powder, limits the drying capacity of flash dryer, leads to existing sudden strain of a muscle
The humidity directly obtained from Molybdenum Mine can not sufficiently be dried for 12%~18% wet molybdenum powder by steaming drying machine, it is therefore necessary to
First passing through combustion gas and the wet molybdenum powder that the humidity obtained in Molybdenum Mine is 12%~18% is dried to humidity is 6%~7%, could be in cylinder
The interior molybdenum powder for being 6%~7% by humidity is dried into molybdenum concentrate, has led to a large amount of consumption of gas energy.
Summary of the invention
It is difficult to wet by what is directly obtained from Molybdenum Mine to solve existing flash dryer since drying capacity is limited
Molybdenum powder is dried into molybdenum concentrate, cause molybdenum ore resource produce in need to dry wet molybdenum powder first with combustion gas and consume a large amount of combustions
The problem of gas energy, the present invention provides a kind of admission gears for molybdenum concentrate flash dryer.
Used technical solution is the present invention to solve above-mentioned technical problem: a kind of for molybdenum concentrate flash dryer
Admission gear, the flash dryer include a hopper and a cylinder for being dried for storing wet molybdenum powder,
The cylinder is vertically arranged, and the feed hopper bottom is equipped with the feed pipe being connected to cylinder lateral wall, is arranged with one on the cylinder
A air inlet cylinder, air inlet cylinder are located at below feed pipe, and the axis for entering the wind cylinder is overlapped with the axis of cylinder, enters the wind the inner wall and cylinder of cylinder
The outer wall of body enters the wind with cricoid hot wind distributor chamber is encircled into and is connected with a blast pipe on cylinder, the axis horizontal of blast pipe is set
It sets and tangent with the inner wall of air inlet cylinder, the waste heat gas outlet of blast pipe and kiln head box enables waste hot air body tangentially
It flows into hot wind distributor chamber and is flowed in hot wind distributor chamber around cylinder body outer wall, the bottom end of cylinder is opening setting, cylinder bottom end
Edge and enter the wind cylinder bottom plate between cooperatively form annular air inlet slit, so that hot wind is distributed indoor waste hot air body and pass through
Annular air inlet slit tangentially flows into cylinder lumen bottom, in order to waste heat gas in cylinder lumen helical flow rise and it is right
Wet molybdenum powder is dried.
Preferably, a transmission shaft, the axis of transmission shaft and the axis weight of cylinder are equipped on the bottom plate of the air inlet cylinder
It closes, blender is set on transmission shaft, blender is located in the inner cavity of cylinder and is located at cylinder close to one end of bottom, enters the wind cylinder
Outside is equipped with the motor for driving transmission shaft to rotate, and so that transmission shaft is able to drive blender and rotates around the axis of cylinder, with
Wet molybdenum powder is avoided to accumulate in cylinder body bottom.
Preferably, the output end of the motor is set with driving pulley, and the bottom end of transmission shaft is set with logical with driving pulley
Cross the passive belt wheel of V belt translation cooperation.
According to the above technical scheme, the beneficial effects of the present invention are:
In the present invention, it is arranged with air inlet cylinder on the cylinder of flash dryer, makes to form cricoid heat between air inlet cylinder and cylinder
Wind distributor chamber, when waste heat gas flows into hot wind distributor chamber by blast pipe, since the inner wall of blast pipe and air inlet cylinder is tangent, waste heat
Gas will tangentially flow into hot wind distributor chamber and flow in hot wind distributor chamber around cylinder body outer wall, and cylinder lumen and hot wind
Unique passage between distributor chamber is cylinder bottom side edge along the annular air inlet slit cooperatively formed between air inlet tube end plate, hot wind
Cylinder lumen will be flowed into from annular air inlet slit by distributing indoor waste heat gas, i.e. waste heat gas is narrow around annular air inlet
During seam flowing, being sent constantly into due to new waste heat gas causes hot wind to distribute indoor air pressure rising, and does spiral shell on one side
It revolves the tangential of one edge annular air inlet slit of annularly flow and enters cylinder lumen bottom, therefore after waste heat gas inflow cylinder lumen
Also it will continue to rise around the axis helical flow of cylinder, and since the width of annular air inlet slit is relative to hot wind distribution
The volume of room is inevitable smaller, makes waste heat gas during through annular air inlet slit, since gas pressure will necessarily be promoted
Flow velocity is matched eventually by hot wind distributor chamber and annular air inlet slit, can after so that waste heat gas is sent into cylinder lumen bottom
High-speed screw flowing rise, with hot gas in the prior art directly from cylinder body bottom flow into compared with, improve waste heat gas in cylinder
Flow effect in inner cavity forms the spiral gas field that circumferential gas velocity significantly improves, makes waste heat gas can in flow process
More efficiently drying is carried out to wet molybdenum powder, improves the drying capacity of flash dryer, it will be able to by humidity be 12%~18%
Wet molybdenum powder be directly dried into molybdenum concentrate, avoid existing flash dryer due to being difficult to is to the humidity obtained in Molybdenum Mine
12%~18% wet molybdenum powder is sufficiently dried, and combustion gas baking must be first passed through in advance to the wet molybdenum powder directly obtained from Molybdenum Mine
Do to humidity be 6%~7% after could be sent into flash dryer the case where, gas energy can be saved.
