Description

A kind of heating rotary kiln
Technical field
The present invention relates to a kind of rotary kiln field, and in particular to a kind of heating rotary kiln.
Background technology
At present, rotary kiln is widely used for thermal technology's firing equipment of the industries such as building materials, metallurgy, chemical industry, non-ferrous metal, and material can be stirred and is axially moveable in tangentially rolling in cylinder.Have the advantages that to be heated evenly, the thermal efficiency is high, continuously can produce, product burning quality is good, save place, mechanization degree is high.Solve conventional tunnel kiln, pushed bat kiln, the material of mesh-belt kiln be heated it is uneven, burn impermeable, high energy consumption, the long cycle the problems such as.
But, the discharging opening of existing rotary kiln rear usually can drop because of refractory brick in roasting process causes blocking, and the temperature of discharging opening material is too high, it is impossible to directly carries out pack storage, increased unnecessary operation, so as to affect efficiency.
Often occur ring formation phenomenon in the production of rotary kiln, the method for big multiplex shut-down labor cleaning, but production is affected, improve production cost.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of convenient disassembly, durable, low consumption, can prevent the heating rotary kiln for blocking.
In order to solve above-mentioned technical problem, the invention provides a kind of heating rotary kiln, it includes kiln body system, kiln tail system, support meanss and sealing device, the kiln body system is made up of kiln head cover and cylinder of rotary kiln, rolling ring is provided with the cylinder of rotary kiln, the support meanss are at least three groups support rollers and gear wheel, the support roller, gear wheel is connected with rolling ring, constitute the bearing column of overall rotary kiln, the kiln tail system is rotary kiln lid, the sealing device is kiln tail seal member and kiln hood seal member, device for transporting objects is provided with the cylinder of rotary kiln, described kiln tail seal member one end is provided with charging aperture, described kiln head cover one end is provided with discharging opening, the kiln body system lower end is provided with transmission system, the transmission system is provided with wheel belt.
As a further improvement on the present invention, the transmission system drives Hardened gear face three-level cylinder gear speed reducer to constitute by adjustable frequency motor.
The kiln hood sealing adds spring tablet Double-layer flexible sealing device using case sealing gland, labyrinth.
The kiln tail sealing adds Flexible graphite to seal using steel disc, and cylinder of rotary kiln wall thickness is 20-25mm, and wheel tape thickness is 65mm.
Compared with prior art, advantage of the present invention is:
The support roller, gear wheel is connected with rolling ring, constitute the bearing column of overall rotary kiln, the kiln tail system is rotary kiln lid, the sealing device is kiln tail seal member and kiln hood seal member, device for transporting objects is provided with the cylinder of rotary kiln, described kiln tail seal member one end is provided with charging aperture, described kiln head cover one end is provided with discharging opening, the kiln body system lower end is provided with transmission system, the transmission system is provided with wheel belt, the device for transporting objects, raw material is transported to into discharge end from feed end, in roasting process, refractory brick does not fall out causes blocking, and fuel combustion, necessary reasonable coordination between heat transfer and raw material motion three, the heat produced by fuel combustion can be just enable to pass through rotary kiln in raw material(Rotary kiln)Time in pass to raw material in time, reached high yield, high-quality, low consumed purpose.
The material of heating rotary kiln is not directly contacted with flame and flue gas, and thermal source is conducted heat come heated material by heat resisting steel barrel between heating furnace and cylinder, and oven inner liner is refractory fibre, energy-saving.
Description of the drawings
Fig. 1 is the structural representation of heating rotary kiln of the present invention.
Specific embodiment
As shown in Figure 1, a kind of heating rotary kiln, it includes kiln body system, kiln tail system, support meanss and sealing device, the kiln body system is made up of kiln head cover 1 and cylinder of rotary kiln 2, rolling ring 3 is provided with the cylinder of rotary kiln 2, the support meanss are at least three groups support rollers 4 and gear wheel 5, the support roller 4, gear wheel 5 is connected with rolling ring 3, constitute the bearing column of overall rotary kiln, the kiln tail system is rotary kiln lid 6, the sealing device is kiln tail seal member 7 and kiln hood seal member 8, device for transporting objects 9 is provided with the cylinder of rotary kiln 2, described 7 one end of kiln tail seal member is provided with charging aperture 10, 1 one end of the kiln head cover is provided with discharging opening 11, the kiln body system lower end is provided with transmission system 12, the transmission system 12 is provided with wheel belt 13.
The transmission system 12 drives Hardened gear face three-level cylinder gear speed reducer to constitute by adjustable frequency motor.The kiln hood sealing adds spring tablet Double-layer flexible sealing device using case sealing gland, labyrinth;The kiln tail sealing adds Flexible graphite to seal using steel disc, and 2 wall thickness of cylinder of rotary kiln is 20-25mm, and wheel tape thickness is 65mm.
In material rotary kiln, the process of calcining is sent into for the charging aperture of raw material, as kiln has certain gradient, and constantly turn round, so that raw material are continuously to hot junction, combustion heat release high-temperature flue gas are produced under air-breathing, in the case where blower fan drives, flow from hot junction to secondary end, heat exchange is carried out in reverse movement so that raw material burn till grog.
The material of heating rotary kiln and flame and flue gas directly contact, stove internal oxidition or reducing atmosphere can be realized by adjusting, cylinder inboard wall builds refractory brick by laying bricks or stones, cover liner is high-strength wear-resistant pouring material end to end, it is flexible sealing between cover and cylinder end to end, can thoroughly prevents airborne dust and material leakage.Multi gear can be taken to support, make barrel lenght reach 60 meters, maximum operation (service) temperature is up to 1600 DEG C.Yield is larger, and it is liquefied gas, natural gas, coal gas, fuel oil, coal dust, coal etc. to be suitable for fuel.
