Description
Technical field
The utility model relates to a kind of rotary kiln field, is specifically related to a kind of heating rotary kiln.
Background technology
At present, rotary kiln is the thermal technology's firing equipment being widely used in the industries such as building materials, metallurgy, chemical industry, non-ferrous metal, and material can tangentially rolling stir and move vertically in cylindrical shell.Have be heated evenly, the thermal efficiency is high, can continuous seepage, product burning quality good, save place, mechanization degree advantages of higher.Solve conventional tunnel kiln, pushed bat kiln, mesh-belt kiln material be heated uneven, burn thoroughly, the problem such as energy consumption is high, the cycle is long.
But the discharging opening of existing rotary kiln rear usually can drop because of refractory brick in roasting process and cause blocking, and the temperature of discharging opening material is too high, can not directly carry out pack and deposit, add unnecessary operation, thus affect efficiency.
In the production of rotary kiln, often there will be ring formation phenomenon, the way of large multiplex shut-down labor cleaning, but impact is produced, improve production cost.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of convenient disassembly, durable, low consumption, can prevent the heating rotary kiln blocked.
In order to solve the problems of the technologies described above, the utility model provides a kind of heating rotary kiln, it comprises kiln system, kiln tail system, bracing or strutting arrangement and sealing device, described kiln system is made up of kiln head cover and cylinder of rotary kiln, described cylinder of rotary kiln is provided with rolling ring, described bracing or strutting arrangement is at least three group support roller and gear wheels, described support roller, gear wheel is connected with rolling ring, form the bearing column of overall rotary kiln, described kiln tail system is rotary kiln lid, described sealing device is kiln tail seal member and kiln hood seal member, device for transporting objects is provided with in described 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, described kiln system lower end is provided with transmission system, described transmission system is provided with wheel belt.
As further improvement of the utility model, described transmission system drives Hardened gear face three grades of cylinder gear speed reducers to form by adjustable frequency motor.
Described kiln hood sealing adopts case sealing gland, labyrinth adds spring tablet Double-layer flexible sealing device.
Described kiln tail sealing adopts steel disc to add Flexible graphite sealing, and cylinder of rotary kiln wall thickness is 20-25mm, and wheel tape thickness is 65mm.
Compared with prior art, the utility model advantage is:
Described support roller, gear wheel is connected with rolling ring, form the bearing column of overall rotary kiln, described kiln tail system is rotary kiln lid, described sealing device is kiln tail seal member and kiln hood seal member, device for transporting objects is provided with in described 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, described kiln system lower end is provided with transmission system, described transmission system is provided with wheel belt, described device for transporting objects, raw material is transported to discharge end from feed end, in roasting process, refractory brick can not drop and cause blocking, and fuel combustion, conduct heat and necessary reasonable coordination between raw material motion three, the heat that fuel combustion just can be made to produce can at raw material by passing to raw material in the time of rotary kiln (rotary kiln) in time, arrive high yield, high-quality, low consumed object.
The material of heating rotary kiln does not directly contact with flame and flue gas, and thermal source is between heating furnace and cylindrical shell, and carry out heated material by the heat transfer of heat resisting steel barrel, oven inner liner is refractory fibre, energy-saving and cost-reducing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model heating rotary kiln.
Detailed description of the invention
As shown in Figure 1, a kind of heating rotary kiln, it comprises kiln system, kiln tail system, bracing or strutting arrangement and sealing device, described kiln system is made up of kiln head cover 1 and cylinder of rotary kiln 2, described cylinder of rotary kiln 2 is provided with rolling ring 3, described bracing or strutting arrangement is at least three group support rollers 4 and gear wheel 5, described support roller 4, gear wheel 5 is connected with rolling ring 3, form the bearing column of overall rotary kiln, described kiln tail system is rotary kiln lid 6, described sealing device is kiln tail seal member 7 and kiln hood seal member 8, device for transporting objects 9 is provided with in described cylinder of rotary kiln 2, described kiln tail seal member 7 one end is provided with charging aperture 10, described kiln head cover 1 one end is provided with discharging opening 11, described kiln system lower end is provided with transmission system 12, described transmission system 12 is provided with wheel belt 13.
Described transmission system 12 drives Hardened gear face three grades of cylinder gear speed reducers to form by adjustable frequency motor.Described kiln hood sealing adopts case sealing gland, labyrinth adds spring tablet Double-layer flexible sealing device; Described kiln tail sealing adopts steel disc to add Flexible graphite sealing, and cylinder of rotary kiln 2 wall thickness is 20-25mm, and wheel tape thickness is 65mm.
In material rotary kiln, the process of calcining is the charging aperture feeding of raw material, because kiln has certain gradient, and constantly turn round, make raw material continuously to hot junction, combustion heat release under air-breathing also produces high-temperature flue gas, under blower fan drives, flows to secondary end from hot junction, carry out exchange heat in reverse movement, make raw material burn till grog.
The material of heating rotary kiln directly contacts with flame and flue gas, realize stove internal oxidition or reducing atmosphere by regulating, cylinder inboard wall builds refractory brick by laying bricks or stones, and cover liner is high-strength wear-resistant pouring material end to end, be flexible sealing between cover and cylindrical shell end to end, thoroughly can stop airborne dust and leak material.Can take many grades of supports, make barrel lenght reach 60 meters, maximum operation (service) temperature can reach 1600 DEG C.Output is comparatively large, and applicable fuel is liquefied gas, natural gas, coal gas, fuel oil, coal dust, coal etc.
