Description
Technical field
The utility model relates to a kind of calciner improving carbonated rare earth day output, belongs to material science.
Background technology
The pre-treatment that existing carbonated rare earth adopts before roasting was sunk the carbonated rare earth slip after process and carry out dehydration centrifuge dripping by entering carbon by scraper centrifugal machine, obtains comparatively dry carbonated rare earth material. There are the following problems in such pre-treatment: 1. after low 4. process of low 3. production efficiencys of big 2. production securities of manpower consumption, humidity of materials is bigger.
Existing rare earth roasting technology is the roasting of mount kiln and tunnel furnace roasting mainly. Mount kiln roasting technology needs artificial loading by carbonated rare earth to be placed in roasting in mount kiln in earthen bowl, and roasting needs after completing to wait cooling, and temperature drops to the artificial reciprocating sieve of room temperature and filters, and packs after mixer batch mixing. Tunnel furnace roasting technology is then that carbonated rare earth material is loaded earthen bowl, puts in push pedal, and push pedal enters roasting in tunnel furnace on tunnel furnace track, and roasting needs after completing to wait cooling, and temperature drops to the artificial reciprocating sieve of room temperature and filters, and packs after mixer batch mixing.
No matter it is mount kiln roasting or tunnel furnace roasting, it is all with old-fashioned kiln roasting, old-fashioned kiln belongs to static roasting, the thermal source provided is uneven and roasting process needs are preferential heats the earthen bowl that rare earth material is housed, then earthen bowl absorbs heat heating material roasting, owing to earthen bowl quantity uses the consumption of the bigger energy relatively big, each roasting all can have a large amount of earthen bowls to damage. And exist and need the artificial problem that filling needs the material of roasting, firing cycle length, production efficiency is low, energy consumption is big.
Practical novel content
The purpose of this utility model is to solve the problem that in existing carbonated rare earth sinter process, manpower consumption is excessive, rare-earth oxidation thing firing cycle is excessively long, production efficiency is low and energy consumption is big, it is provided that a kind of calciner improving carbonated rare earth day output.
The purpose of this utility model is achieved through the following technical solutions.
Improving a calciner for carbonated rare earth day output, concrete steps are as follows:
The hot blast that step one, rare earth carbonate enter the drying utilizing hotblast stove to provide in transfer lime makes dry materials, and when induced draft fan provides power, and the carbonated rare earth that total mass is greater than 70% is undertaken by cyclonic separator being separated, blanking;
The material being carried away by the wind in step 2, sepn process, through bag collection, then passes through bag collection feed opening blanking;
Step 3, the described blanking of step one Yu step 2 gained is put into kiln head receiving hopper, then by strand dragon controlled frequency stable at the uniform velocity to feeding in rotary kiln;
Step 4, material are copied plate by the size on barrel in kiln and are carried out turning over material, the speed that back-up ring control material runs in rotary kiln, and the two can keep material evenly to carry out roasting slowly in rotary kiln; Then expect in container under kiln tail;
Step 5, when induced draft fan provide power, material in container is lowered the temperature through transfer lime conveying simultaneously, undertaken by cyclonic separator being separated again, blanking, the material being carried away by the wind in sepn process through dust collection equipment, then by dust collection equipment feed opening blanking; Obtain final rare earth oxide product.
Described rotary kiln end kiln tail obliquity is 1 ��;
Realize the calciner improving carbonated rare earth day output, comprise rotary kiln, cyclonic separator, dust collection device, induced draft fan, strand dragon, kiln head receiving hopper, hotblast stove, transport pipe;
One end of transport pipe is connected with cyclonic separator, and the other end is connected with hotblast stove by pipeline; Being provided with strand dragon on transport pipe, dragon is connected strand with receiving hopper, and by receiving hopper, through twisting, dragon enters transport pipe to pending carbonated rare earth; Induced draft fan, dust collection device are connected by pipeline successively with cyclonic separator; Kiln head receiving hopper is connected with strand dragon; It is outside to expecting kiln that strand dragon is positioned at rotary kiln end, and rotary kiln will be expected under material in container; Container, cyclonic separator, dust collection device are connected by pipeline successively with induced draft fan;
Useful effect
1, the device and method of rotary kiln baking carbonated rare earth is utilized, rotary kiln is expected under material is direct after air stream drying pre-treatment, adding the dynamic roasting of rotary kiln, kiln tail uses cyclonic separator and bag collection equipment to collect product so that producing can the carrying out of Automatic continuous. Kiln head to material and kiln tail blanking not to need artificially to fill out solve old-fashioned kiln artificial and is filled out the excessive problem of the manpower consumption of kiln; Dynamically roasting shortens the roasting time comparing old-fashioned kiln continuously; Rotary kiln baking ability is higher than the roasting capacity of old-fashioned kiln, and day output is equivalent to 2 times of the day output of old-fashioned kiln;
2, rotary kiln belongs to dynamic roasting, the cylinder material that thermal source direct heating rotates constantly rolls in kiln and can be heated uniformly, the more high entropy of material confusion degree is more high, endothermic effect is more good, roasting directly carries out in the cylinder of kiln, not needing to use earthen bowl, cylinder is much smaller compared with earthen bowl heating surface area, so the dynamic roasting energy consumption of rotary kiln to be far smaller than the static roasting of old-fashioned kiln.
3, air stream drying of the present utility model process, the total amount of carbonated rare earth can be dried more than 70% by air stream drying process, and the total amount of carbonated rare earth can be dried about 45% by whizzer centrifuge dripping carbonated rare earth, the carbonated rare earth of air-flow process meets the requirement that material enters rotary kiln completely
4, whizzer need manually to carry out to feed in raw material, scraper danger relatively big, air-flow process carbonated rare earth is that the security of production is improved by artificial remote electrically controlled case control greatly
5, centrifuge dripping carbonated rare earth material needs hand-fed, scraper and manually carries out pack process, and air stream drying utilizes cyclonic separator and bag collection that material carries out blanking process directly to join in rotary kiln material without the need to manually.
