Abstract
A kind of continuous powdery sintering rotary furnace, the problem solving is in conventional art, to have the interval uppity problem of the time of staying of different temperatures in continuous rotary furnace, the technical solution adopted in the utility model is as follows: a kind of continuous powdery sintering rotary furnace, comprise feed arrangement, preheating rotary furnace, high temperature rotating stove, preheating rotary furnace and high temperature rotating stove are by rotating cylinder, the helical blade that is built in rotating cylinder inwall forms, be welded on preheating rotary furnace different from the pitch of the helical blade diverse location of high temperature rotating furnace roller inwall, pitch distribution was determined according to the time of powder material required stop under the inner different temperatures of body of heater.In the utility model, because rotating cylinder inwall is welded with the pusher blade of screw type, measure-alike and pitch is different, powder flowing velocity in rotating cylinder is different, powder can change by changing helical blade pitch in the time of staying of different temperatures section, thereby had solved powder material uppity problem of the needed time of staying under different temperatures.
Description
Technical field
The utility model relates to a kind of continuous powdery sintering rotary furnace, belongs to chemical powder material sintering technology field.
Background technology
Sintering process is critical workflow prepared by the powders such as electrode material, ceramic material.Especially the intensification of sintering process, insulation, cooling time are controlled sintering quality are played to decisive role.At present, the shortcoming of sintering furnace mainly contains that sintering energy consumption is large, the cycle is long, charging tray service life is short, complicated operation, production efficiency are low, the inequality of being heated, to be incubated the cooling time wayward.
Powder sintering is generally divided into two large classes with rotary furnace: batch (-type) rotary furnace and continuous rocking furnace.Batch (-type) rotary furnace is that a certain amount of material is once packed in rotary furnace and heated, and during discharging, body of heater jack-up be tilted to pour out material, and complex operation, easily destroys body of heater, and cycle length, thermal waste, energy consumption greatly, be heated inhomogeneous.Continuous rotary kiln furnitures have the advantages such as production material quality is even, the efficiency of heating surface is high, air-tightness is good, atmosphere performance is good, are widely used in recent years the fields such as dry, calcining, pyroreaction, heat treatment, carbonization of the powder of lithium ion battery material, rare earth material, chemical catalyst material, magnetic material, powdered metallurgical material, nonferrous materials and kaolin nonmetallic mineral material or particle.As the patent No. a kind of Full-sealing continuous rotary furnace that is 200720031819, it comprises feed system, discharge system, revolution body of heater, stove head seal combination, stove tail seal combination, material enters burner feed bin from burner, enter into the boiler tube of rotary furnace along powder delivery system among, heat and calcine, to the other end (kiln tail), slowly move simultaneously, two endfeeds and the output section of the boiler tube of body of heater are actionless, boiler tube rotates, between the sound of burner and stove afterbody coordinates, sealing system is set and forms sealing, make material react heating under atmosphere is controlled, reach atmosphere and control calcining.
For above two class rotary kilns, in powder sintering process, to require temperature retention time be the time of staying to be difficult to realize when different in different temperatures interval.
Summary of the invention
Problem to be solved in the utility model is in conventional art, to have the interval uppity problem of the time of staying of different temperatures in continuous rotary furnace, and a kind of new continuous rotary furnace is provided.This rotary furnace has a powder time of staying and is easy to control, and material such as is heated evenly at the advantage.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of continuous powdery sintering rotary furnace, it is characterized in that: comprise feed arrangement, preheating rotary furnace, high temperature rotating stove, preheating rotary furnace and high temperature rotating stove are comprised of rotating cylinder, the helical blade that is built in rotating cylinder inwall, be welded on preheating rotary furnace different from the pitch of the helical blade diverse location of the inner wall of rotary drum of high temperature rotating stove, pitch distribution was determined by the time of powder material required stop under the inner different temperatures of body of heater.
According to described continuous powdery sintering rotary furnace, the material of described helical blade is metal material or refractory material, and the helical blade that is welded on rotating cylinder inwall is pusher screw type, and helical blade axis is parallel to the central axis of its place body of heater.
In the utility model, because rotating cylinder inwall is welded with the pusher blade of screw type, measure-alike and pitch is different, powder flowing velocity in rotating cylinder is different, powder can change by changing helical blade pitch in the time of staying of different temperatures section, thereby had solved powder material uppity problem of the needed time of staying under different temperatures.

Fig. 2 is the A-A cutaway view of the utility model Fig. 1.
In accompanying drawing: 1, feed arrangement; 2, preheating rotary furnace; 3, high temperature rotating stove; 4, rotating cylinder; 5, helical blade.
The specific embodiment
Embodiment
The utility model, as a kind of continuous powdery sintering rotary furnace, comprises feed arrangement 1, preheating rotary furnace 2, high temperature rotating stove 3.Preheating rotary furnace 2 and high temperature rotating stove 3 comprise rotating cylinder 4, are built in the helical blade 5 of rotating cylinder inwall.It is characterized in that: the helical blade 5 that is welded on preheating rotary furnace 2 and the inwall of high temperature rotating stove 3 rotating cylinders 4 is measure-alike and pitch is different, pitch distribution designed according to powder material needed time of staying under different temperatures, make powder flowing velocity in rotating cylinder different, make the interval lower time of staying of different temperatures be easy to control.
In technique scheme, the material of helical blade 5 is metal material or refractory material; The helical blade 5 that is welded on rotating cylinder 4 inwalls is pusher screw type, and its axis is parallel to preheating rotary furnace 2 and high temperature rotating stove 3 central axis.
As Fig. 1, when continuity powder is when sintering rotary furnace rotating cylinder 4 is done to slowly run, by feed arrangement 1, send into the screw forward under the frictional force effect of self and helical blade 5 of powder material in rotating cylinder 4.When rotating cylinder 4 rotates, because helical blade 5 pitch differences are the number difference of unit distance internal thread, material is different in the horizontal velocity of diverse location.The temperature of rotating cylinder 4 diverse locations is controlled by external heat source, and rotating cylinder 4 diverse locations can corresponding different temperatures.Control rotating cylinder 4 speed and each regional temperature and can control the time of staying in different temperatures interval.(helical blade 5 pitch distribute can according to material in variant temperature range the required time of staying than calculating with the data such as rotating cylinder 4 total lengths.) therefore, the utility model is by adopting helical blade 5 measure-alike and that pitch is different to realize the simple control of the interval different time of staying of different temperatures.
Embodiment recited above is described preferred embodiment of the present utility model; not design of the present utility model and protection domain are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model, all should fall into protection domain of the present utility model.
