Abstract
The invention provides a rotary kiln energy-saving method and belongs to the technical field of rotary kilns. The method includes the specific steps that a transmission device is installed in the middle of a kiln cylinder and close to a two-gear wheel belt, and energy-saving composition bricks are built on the position of the two-gear wheel belt; the temperature of the outer surface of the kiln cylinder is controlled to be 250 DEG C or below. The method has the advantages that torque generated by transmission of a kiln power system is reduced, the aim of saving electricity is achieved, and high requirements caused by large torque for refractory materials are reduced.
Description
Technical field
The invention belongs to rotary kiln technical field, particularly to a kind of method of rotary kiln energy-conservation.More particularly, to a kind of energy
Reduce kiln cylinder body to greatest extent to economize on electricity and power-saving technology because the moment of torsion that power transmission produces reaches.
Background technology
Rotary kiln is a kind of Thermal Equipment that bulk material is carried out with heat treated, is widely used in metallurgy, chemical industry, cement
The industrial departments such as building materials.Rotary kiln is mainly by parts groups such as cylinder, support meanss, actuating device, sealing device, fire resisting kiln linings
Become.Existing all kinds of rotary kiln dynamical system is too high due to kiln cylinder body external skin temperatures, for protection actuating unit long-term safety fortune
OK, power drive system, all not at the middle part of kiln body length, is generally located at 1/3rd of kiln cylinder body length, so kiln
Larger not reciprocity moment of torsion can be produced, the moment of torsion of kiln is big, and corresponding Main motor current is also big, and power consumption is high during power transmission.In addition
Larger moment of torsion makes kiln cylinder body Light deformation also increase, and also becomes big to the extrusion stress of refractory material in kiln, refractory material quilt in kiln
Squeeze crack comes off risk change greatly, causes very big difficulty to production and maintenance.
Content of the invention
It is an object of the invention to provide a kind of method of rotary kiln energy-conservation, produce larger when solving kiln power transmission
Not reciprocity moment of torsion leads to the high problem of power consumption.By kiln actuating unit being moved at 1/3rd of kiln length kiln length
Centre, make kiln be driven produce moment of torsion be reduced to less scope, reach the purpose of economize on electricity.In addition moment of torsion reduces can make kiln cylinder
Body steel plate thickness is thinning, weight saving, thus reducing the manufacturing cost of rotary kiln.
A kind of method of rotary kiln energy-conservation, specifically comprises the following steps that
1st, actuating device 3 is arranged on kiln cylinder body 1 medium position, near two grades of wheel belt 2, at two grades of wheel belt 2, builds section by laying bricks or stones
Can composite brick 4.
2nd, energy-saving composite brick 4 is built by laying bricks or stones at two grades of wheel belt 2, and kiln cylinder body 1 external skin temperatures control below 250 DEG C, and protection is dynamic
Run in high temperature environments by long-term safety for force actuators equipment.
It is an advantage of the current invention that: reduce kiln dynamical system transmission produce moment of torsion, reach economize on electricity purpose and reduce because
The high requirement that moment of torsion proposes greatly and to refractory material.In addition kiln cylinder body external skin temperatures are made to reduce using energy-saving composite brick, insulation
Effect more preferably, reduces coal consumption, and after energy-saving composite brick compares traditional refractory brick substance mitigation simultaneously, required motor power diminishes,
Select to select a little grade motor during motor.
Brief description
Fig. 1 is rotary kiln actuating unit position view of the present invention.Wherein, kiln cylinder body 1, two grades of wheel belt 2, transmission dress
Put 3, energy-saving composite brick 4.
Specific embodiment
Embodiment 1
