Description
Technical field
The present invention relates to a kind of calcining kiln, more particularly to a kind of interior heat pipe rotary calciner.
Background technology
At present, rotary kiln can be divided into cement rotary kiln, ceramsite sand rotary kiln, kaolin rotary kiln, stone according to purposes point
Grey rotary kiln etc..Rotary kiln in many production industries such as building materials, metallurgy, chemical industry, environmental protection, is widely used to solid
Material carries out machinery, a kind of revolving drum equipment of physical or chemical treatment.Traditional rotary calciner, the drying calcining of material
It is to realize that drying calcination processing requires by directly being contacted with heat smoke with the two ways of mediate contact.However, due to
Operation of the material in cylinder is realized by the angle of inclination of cylinder and the height of lifting blade in cylinder.For mobility
Material good, viscosity is weaker, under the lifting effect of the inclination angle of cylinder and lifting blade, drying calcination time is too short, and material is not
Reach calcining to require just to be sent from kiln tail, as underburnt state；For the stronger material of poor fluidity, viscosity, material
And glutinous absorption easy to stick acts on the lifting of lifting blade and is restricted on lifting blade, only conveys material, conveying effect by barrel body rotation
Fruit is undesirable, and it is long to often lead to material discharging time, and material condition exceedes calcining and requires just to be sent out from kiln tail, as burning
State.Due to this respect, the application of rotary calciner is also limited by very large.

Dry chamber is calcined intracavitary and is fixed on kiln barrel；The kiln hood end plate is arranged at kiln head cover, and kiln tail end plate is arranged at kiln hood
Place；The blocking material ring, kiln hood end plate are identical with kiln tail tip plate configurations, and surface offers the triangle lifting of multiple circumference equidistant arrangements
Airduct hole；The triangle lifting airduct is located on triangle lifting airduct hole.
The blocking material ring is at least one, is uniformly arranged on drying calcining intracavitary, and drying calcining chamber is divided into multiple sizes one
The chamber of cause.
The triangle lifting airduct is triangle zona columnaris lifting side structure, and one end is fixed on kiln hood end plate, and one end is fixed
In on kiln tail end plate, centre passes through blocking material ring, is circled with cylinder.
The kiln body also includes gas furnace and pipe screw feed mechanism；The kiln hood side is provided with gas furnace air inlet
Mouthful, air inlet one end is connected one end with triangle lifting airduct and is connected with gas furnace, and kiln hood bottom is provided with discharging opening；The kiln
Charging aperture is provided with head-shield, charging aperture is connected with pipe screw feed mechanism.
Compared with prior art, just some has the beneficial effect that：It is high by cylinder of rotary kiln angle of inclination and lifting blade lifting
Degree or the height and angle on triangle lifting airduct lifting side, and the quantity of blocking material ring and blocking material ring inner ring height, and then control
Material promotes the speed of service, and effect is calcined with the drying for reaching optimal.

Embodiment
It is illustrated as a kind of embodiment of heat pipe rotary calciner in the present invention, including kiln head cover, kiln body 2, kiln hood, kiln hood
Cover and kiln hood are respectively arranged at the both ends of kiln body；The kiln body includes kiln barrel 3, lifting blade 7, triangle lifting airduct 5, backgauge
Ring 4, kiln hood end plate 1 and kiln tail end plate 6；The cylindrical-shaped structure that the kiln body is surrounded by kiln barrel, it is interior for drying calcining chamber；Institute
State lifting blade and blocking material ring is arranged at drying cavity calcining intracavitary and is fixed on kiln barrel；The kiln hood end plate is arranged at kiln head cover
Place, kiln tail end plate are arranged at kiln hood；The blocking material ring, kiln hood end plate are identical with kiln tail tip plate configurations, and surface offers more
The triangle lifting airduct hole of individual circumference equidistant arrangement；The triangle lifting airduct is located on triangle lifting airduct hole；The gear
Expect that ring is at least one, be uniformly arranged on drying calcining intracavitary, drying calcining chamber is divided into multiple chambers of the same size；Described three
Lifting airduct in angle is triangle zona columnaris lifting side structure, and one end is fixed on kiln hood end plate, and one end is fixed on kiln tail end plate, in
Between pass through blocking material ring, circled with cylinder；The kiln body also includes gas furnace and pipe screw feed mechanism；The kiln hood
Side is provided with gas furnace air inlet, and air inlet one end is connected one end with triangle lifting airduct and is connected with gas furnace, under kiln hood
Portion is provided with discharging opening；Charging aperture is provided with the kiln head cover, charging aperture is connected with pipe screw feed mechanism.
High temperature（More than 1000 DEG C）The corrosivity of material is larger, a kind of interior heat pipe rotary calciner overall structure portion of the present invention
Part is made using 316L materials.
Drying materials calcining of the present invention and the original of kiln body angle of inclination and the lifting blade lifting height control material speed of service
Reason is as follows：Material feeds charging aperture from the spout of kiln hood, under the push effect of pipe spiral, is transported to drying calcining furnace chamber
It is interior.Heat smoke, into triangle lifting airduct, is taken out from the hot-blast stove of kiln body afterbody by whole kiln body and kiln tail outlet housing by blower fan
Go out, form a flue gas fluid thermal wind field, carrying out drying calcining for the material Jing Guo kiln body provides thermal source.Material tilts in kiln body
In the presence of rotation, entered first by kiln hood end plate in furnace chamber, raised first with the triangle by heat smoke heating in furnace chamber
Expect airduct row heat exchange, drying calcining is carried out to material.The top layer material contacted with warm-air pipe is first dried by flue gas hot air duct,
Again cylinder inboard wall lifting blade and triangle lifting airduct lifting with kiln body turning effort, kicked up and spread repeatedly in furnace chamber body
Material, to material carry out upset drying calcining, and with barrel body rotation collective effect, material is pushed to kiln tail.For flowing
Property good, material that viscous stickiness is weaker, it is very fast to be advanced toward the speed of service in kiln body, prevents that material from being sent out kiln body in advance,
Extend drying calcination time, Liao Ji roads blocking material ring is added in rotary kiln body.On the one hand the operation speed that material is advanced toward is slowed down
Degree, on the other hand due to the heating of triangle lifting warm-air pipe so that blocking material ring temperature is also higher, and secondary drying is played to material
Calcining acts on.The structure design of triangle lifting airduct, the contact area of thermal source and material is on the one hand greatly increased, improve drying effect
Fruit, another aspect airduct are provided with lifting side plate close to cylinder pivot the inner, and material is kicked up height and greatly increased, drying effect
Fruit greatly improves.For the stronger material of poor fluidity, viscous stickiness, pushing speed is slower forward in kiln body, triangle lifting heat
The design of airduct, material is accumulated with heat-source contacting surface and increase, the surface of material contacted at first with warm-air pipe is oven-dried, viscosity drop
It is low, start to be advanced toward, improve pushing efficiency of the material in kiln body, while the material being oven-dried is in itself also with higher
Heat energy, secondary drying is carried out to the rear material being in contact with it into kiln body.Equally distributed warm-air pipe quantity is more, drying calcining
Effect is better.
