Detailed Description
The following is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1-2:
a waste heat recovery device of a rotary kiln is arranged on a rotary kiln 3, the rotary kiln 3 comprises a base 4 and a barrel 5, and the barrel 5 is rotatably arranged on the base 4.
The waste heat recovery device comprises a heat storage tank 1 and a recovery pipe 2.
The heat storage tank 1 is in a U-shaped shape, a heat storage chamber is arranged in the heat storage tank, the U-shaped opening of the heat storage tank 1 faces downwards, two sides of the heat storage tank 1 are fixedly installed on the base 4, a central shaft of a bending part of the heat storage tank 1 coincides with a central shaft of the barrel 5, so that the heat storage tank 1 is located on the periphery of the barrel 5 and is not in contact with the barrel 5, and heat can be conducted between the barrel 5 and the heat storage tank 1 through air.
The both ends of heat storage tank 1 are along the circumference fixed mounting of barrel 5 has a plurality of fish scale 9 that staggers each other and distributes, and the one end butt of keeping away from heat storage tank 1 on fish scale 9 is on barrel 5, and fish scale 9 makes heat storage tank 1 form sealed the covering in the upper portion of barrel 5 when not influencing barrel 5 pivoted to make the heat that barrel 5 effused can be more conduct in heat storage tank 1, effectively improve whole waste heat recovery efficiency to rotary kiln 3.
There are a plurality of heat-conducting plates 7 along the circumference fixed mounting of barrel 5 in the heat storage tank 1, heat-conducting plate 7 is located the footpath of barrel 5, it is made by the good materials of heat conductivility such as aluminum alloy, integrated into one piece has cover plate 8 after heat storage tank 1 is worn out to the one end of heat-conducting plate 7, cover plate 8 is close to barrel 5 but not contact with barrel 5, it is the same with heat-conducting plate 7's material, through heat-conducting plate 7 and cover plate 8, can effectively promote the heat conduction efficiency between barrel 5 and the heat storage tank 1, make whole waste heat recovery efficiency to rotary kiln 3 higher.
