Technical field
This utility model relates to field of cement production equipment, is specifically related to a kind of frequency conversion bi-motor rotary kiln.
Background technology
Cement rotary kiln is the capital equipment of clinker dry and wet production line.Rotary kiln is widely used in the industry such as metallurgy, chemical industry, building refractory material, environmental protection.nullRotary kiln is by cylinder，Supporting arrangement，Band gear wheel supporting arrangement，Actuating device，Movable kiln hood,Compound lithotrite，Kiln tail sealing device，The parts compositions such as coal injection pipe device，Rotary kiln power of motor needed for different working stages is different，Immediately below during startup, the material in rotary kiln is in，During kiln body starts and constantly accelerates，Whole kiln body frictional force to be overcome、The resistance that solid accumulation angle in the resistance of kiln body deformation generation and kiln produces，The most required torque and power are minimum，Once converter overcomes this large inertia load and rises and move up，When maintaining normal operation，Required driving torque and power are the least，And the motor speed of existing rotary kiln is unadjustable，Motor with fixed rotating speed operating or can only be adjusted by reduction box，And the reduction box buying of band gearshift and maintenance cost are higher，And electrodeless variable-speed cannot be realized，Cannot accurately adjust rotating speed；In addition motor is to be dried by the coaxial fan of oneself to dispel the heat, and when the rotating speed of motor declines bigger, the radiating effect of motor is very poor, causes electric motor overheating serious
Utility model content
For overcoming deficiency of the prior art, this utility model provide a kind of start rapidly, stepless time adjustment, the frequency conversion bi-motor rotary kiln of good heat dissipation.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of frequency conversion bi-motor rotary kiln, it is characterized in that: include kiln body, riding wheel apparatus, master driver, auxiliary actuator, converter, water pump, water tank and cold type, described kiln body is rotating to be arranged on riding wheel apparatus, described master driver includes mair motor and main reducing gear, mair motor drives kiln body to rotate by main reducing gear, described auxiliary actuator includes stand-by motor and aux. retarder, stand-by motor drives kiln body to rotate by aux. retarder, described converter is connected with mair motor and stand-by motor by circuit, the motor casing of described mair motor and stand-by motor is equipped with hollow layer, water pump, hollow layer, cold type passes sequentially through pipeline connection with water tank and becomes circulation waterway.
Further, the water inlet pipe of the hollow layer of described stand-by motor is provided with electromagnetic valve.
Further, described riding wheel apparatus is made up of two support roller parts, and each support roller part includes pedestal and the support roller being arranged on pedestal, and the corresponding each support roller part of the outer wall of described kiln body is provided with the support roller groove of annular, and support roller moves along support roller trough roller.
Further, described kiln body outer wall is provided with gyration gear ring.
Further, the output gear of described main reducing gear and aux. retarder all engages with the gyration gear ring of kiln body.
Seen from the above description, bi-motor is used jointly to drive when the frequency conversion bi-motor rotary kiln that this utility model provides starts, big torque required when starting with offer, single motor work is then used when rotary kiln at the uniform velocity operates, save energy consumption, motor is started by converter, can the rotating speed of the most electrodeless regulation rotary kiln, to adapt to different technological requirements, electric motor starting is soft start, super-high-current is avoided to bring impact to electrical network, use water cooled heat radiating, guarantee that motor all keeps good radiating condition when starting or run well, ensure that rotary kiln normally works.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model frequency conversion bi-motor rotary kiln.
Fig. 2 is the top view of this utility model frequency conversion bi-motor rotary kiln.
Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
nullAs depicted in figs. 1 and 2，Described frequency conversion bi-motor rotary kiln includes kiln body 1、Riding wheel apparatus 2、Master driver 3、Auxiliary actuator 4、Converter 5、Water pump 6、Water tank 7 and cold type 8，Described kiln body 1 is rotating to be arranged on riding wheel apparatus 2，Described riding wheel apparatus 2 is made up of two support roller parts，Each support roller part includes pedestal 21 and the support roller 22 being arranged on pedestal 21，The corresponding each support roller part of the outer wall of described kiln body 1 is provided with the support roller groove 11 of annular，Support roller 22 rolls along support roller groove 11，Described master driver 3 includes mair motor 31 and main reducing gear 32，Mair motor 31 drives kiln body 1 to rotate by main reducing gear 32，Described auxiliary actuator 4 includes stand-by motor 41 and aux. retarder 42，Stand-by motor 41 drives kiln body 1 to rotate by aux. retarder 42，Kiln body 1 outer wall is provided with gyration gear ring 12，The output gear of main reducing gear 32 and aux. retarder 42 all engages with the gyration gear ring 12 of kiln body 1，Described converter 5 is connected with mair motor 31 and stand-by motor 41 by circuit，The motor casing of described mair motor 31 and stand-by motor 41 is equipped with hollow layer，Water pump 6、Hollow layer、Cold type 8 passes sequentially through pipeline connection with water tank 7 and becomes circulation waterway，The water inlet pipe of the hollow layer of stand-by motor 41 is provided with electromagnetic valve 411.
