A big chunk fuel can be drained along taking chimney to, so as to cause the waste of big energy, and can also aggravated to environment
Pollution, cause serious air pollution.
Utility model content
The purpose of this utility model is to overcome current rotary kiln heat easily to distribute, afterbody air inducing is by the direct band of heat
Walk the waste that causes a large amount of heat energy and to air it is seriously polluted the problem of, and provide a kind of revolution for carrying out UTILIZATION OF VESIDUAL HEAT IN
Kiln, the rotary kiln are effectively utilized the waste heat of high-temperature region sintered products, and the drying of moisture has been carried out to back segment product, effectively save
The energy, and pollution index is significantly reduced, more environmental protection and energy saving.
What the utility model was realized in：A kind of rotary kiln for carrying out UTILIZATION OF VESIDUAL HEAT IN, including the revolution being obliquely installed
Kiln body, the rotary kiln inner body wall are provided with furnace lining heat-insulation layer, and rotary kiln body both ends are respectively arranged with feeding mouth and gone out
Material mouth, is provided with partition wall in the rotary kiln body, and rotary kiln body is separated into high-temperature region and baking zone by partition wall, high-temperature region with
Discharging opening is adjacent, and baking zone is adjacent with feeding mouth, and ventilating opening and manhole are provided with the partition wall.
The above-mentioned rotary kiln for carrying out UTILIZATION OF VESIDUAL HEAT IN, the partition wall are vertically arranged, and partition wall surrounding is fixedly installed in furnace lining
On heat-insulation layer.
The above-mentioned rotary kiln for carrying out UTILIZATION OF VESIDUAL HEAT IN, the ventilating opening are circular hole.
The above-mentioned rotary kiln for carrying out UTILIZATION OF VESIDUAL HEAT IN, the manhole are arranged at the center of partition wall, and the ventilating opening is uniform
It is distributed in around manhole.
The utility model has the following advantages that：The rotary kiln of the present utility model for carrying out UTILIZATION OF VESIDUAL HEAT IN is effectively utilized
The waste heat of high-temperature region sintered products, the drying of moisture is carried out to back segment product, has been effectively saved the energy, has greatly reduced production
Cost, the market competition rate of product is improved, after the energy is utilized effectively, hence it is evident that pollution index is reduced, it is more environmentally friendly
Energy-conservation.

In figure：1- rotary kiln bodies, 2- furnace lining heat-insulation layers, 3- feeding mouths, 4- discharging openings, 5- partition walls, 6- high-temperature regions, 7- dry
Dry area, 8- ventilating openings, 9- manholes.
Embodiment
With reference to specific embodiment, the utility model will be further described.
Embodiment 1：A kind of rotary kiln for carrying out UTILIZATION OF VESIDUAL HEAT IN, as shown in figure 1, including the rotary kiln body being obliquely installed
1, about 45 meters of rotary kiln body total length, about 2.2 meters of diameter, rotary kiln body pass through regulation motor speed regulator drive rotary kiln body
Rotate, reach the velocity of rotation required for production；The inwall of rotary kiln body 1 is provided with furnace lining heat-insulation layer 2, and furnace lining is protected
Warm layer 2 is phosphate high alumina heat insulation composite brick, and rotary kiln crust is provided with high temperature glass wool and is used to be incubated, and can ensure heat
Maximally utilize, avoid causing thermal loss；The both ends of rotary kiln body 1 are respectively arranged with feeding mouth 3 and discharging opening 4, discharging opening
There is fuel at place 4, can burn and heat energy is discharged into rotary kiln body 1 by blower fan, is that the material in rotary kiln is heated；
Partition wall 5 is provided with the rotary kiln body, partition wall is vertically arranged, and partition wall surrounding is fixedly installed on furnace lining heat-insulation layer 2, partition wall
Rotary kiln body is separated into high-temperature region 6 and baking zone 7, high-temperature region 6 and the phase of discharging opening 4 by 5 apart from about 21 meters of discharging opening 4, partition wall
Neighbour, baking zone 7 is adjacent with feeding mouth 3, and ventilating opening 8 and manhole 9 are provided with partition wall 5, and ventilating opening is circular hole, is easy to material
Flowing, manhole are arranged at the center of partition wall 5, and the ventilating opening 8 is uniformly distributed in around manhole 9, is convenient for repairing.Returning
The feeding mouth 3 of rotary kiln body is added after material is burnt, and most of heat at discharging opening 4 enters high-temperature region 6, and minor heat leads to
The ventilating opening 8 crossed on partition wall 5 is drawn out to baking zone 7, and then this part of waste heat can carry out prebake to the material of baking zone 7,
Material can dry moisture in baking zone, save the energy；When material advances to rotary kiln partition wall, the bottom of partition wall 5
The air vent 8 in portion has reformed into the passage that material leads to discharging opening 4, and material is sintered by rear into high-temperature region 6.The revolution
The heat energy that kiln can make full use of fuel combustion to discharge by setting up partition wall 5, reduce fuel and fuel taken away because of kiln tail air inducing,
The waste of fuel is effectively prevent, conventional 1 ton of product of rotary kiln about consumes 110 ~ 130 side's natural gases, uses 1 ton after the equipment
Product consumes the side of natural gas about 80 ~ 90, and energy-conservation reaches more than 30% produced in the past, greatly reduces production cost, reach energy-conservation
The effect of environmental protection.
