Abstract
A rotary kiln heat-resistant residual-heat recovering device relates to the field of the rotary kiln heat energy recovering technology, which comprises a rotary kiln body, and is characterized in that the outer side of the rotary kiln body is provided with lifting plates, and a shell which is in sealed connection and coaxial with the rotary kiln body; the shell is fixed on the foundation, the upper side of one end of the shell is provided with an inlet, the lower side of the other end thereof is provided with an outlet, and the inner side of the shell is provided with a heat-resisting layer. The lifting plates are uniformly distributed on the outer side of the rotary kiln body, and the clearance between the tail end of the lifting plate and the inner wall of the shell is less than 2cm. Through arranging a cavity on the outer side of the rotary kiln body, and using with the lifting plates on the outer side of the rotary kiln body, the rotary kiln heat-resistant residual-heat recovering device can be directly used for pre-heating the powder material and improve the energy-saving effect.
Description
Technical field
The utility model relates to rotary kiln heat energy utilization technical field, the high temperature resistant residual heat using device of specifically a kind of rotary kiln.
Background technology
In industries such as metallurgy, cement, rotary kiln is widely used as a kind of drying plant.In high temperature section, rotary kiln surface temperature reaches more than 1000 ℃, all adopts air-cooled or water-cooled cooling, a large amount of heat energy directly to be dispersed in the atmosphere at present, and this has not only wasted a large amount of heat energy, has also caused kiln body high temperature on every side to pollute.The lost heat energy in kiln surface can be recycled in fact.Common way is, according to the needs of enterprise, the heat energy that reclaims added hot water or air, and hot water can be for life and refrigeration, and hot-air can be used for oven dry.Can reduce kiln body temperature degree and save again and add the hot water or required fuel cost, the fan electricity charge of air, reduce dust and CO2 emission.
These all are the simple utilizations to kiln surface heat energy.If can utilize the material of the direct preheating production of heat energy usefulness, can save to produce and drop into, will reduce greatly to produce and use coal, reduce production costs.
The utility model content
The purpose of this utility model is to provide a kind of rotary kiln high temperature resistant residual heat using device, can be used for direct preheating split material, has the high-temperature-resistant thermal-insulation layer simultaneously, and energy-saving effect is obvious.
The technical scheme in the invention for solving the technical problem is: the high temperature resistant residual heat using device of this kind rotary kiln, comprise the rotary kiln body, it is characterized in that, the outside is provided with lifting blade on the described rotary kiln body, be provided with the rotary kiln body in the external side of described rotary kiln and be tightly connected and coaxial housing, described housing is fixed on the ground, and the upside of an end of described housing is provided with charging aperture, other end downside is provided with discharging opening, and the inboard of described housing is provided with refractory layer.
Described lifting blade is distributed on the external side of rotary kiln, and the gap between described lifting blade end and the inner walls is less than 2 centimetres.
Described refractory layer is formed by refractory ceramics brick combination place mat.
The beneficial effects of the utility model are: the high temperature resistant residual heat using device of this kind rotary kiln, by the arranged outside cavity of rotary kiln body, cooperate rotary kiln will carry the lifting blade in the outside, can be used for direct preheating split material, have the high-temperature-resistant thermal-insulation layer simultaneously, energy-saving effect is obvious.
Description of drawings
Fig. 1 is an axial section view of the present utility model;
Fig. 2 is the A-A sectional drawing;
Among the figure: 1 kiln body, 2 housings, 21 refractory ceramics layers, 3 lifting blades, 4 charging apertures, 5 discharging openings, 6 supports, 7 sealing strips, 8 grounds, 9 cavitys.
The specific embodiment
As shown in Figure 1 and Figure 2, the high temperature resistant residual heat using device of this kind rotary kiln comprises rotary kiln body 1, is positioned at housing 2, the support 6 of the external side of kiln.
Described rotary kiln body 1 is fixed on the ground 8 by bearing is rotatable, forms some lifting blades 3 in the external side of kiln by welding, and described lifting blade is distributed on the external side of rotary kiln, and the terminal gap with housing 2 inwalls of described lifting blade 3 is less than 2 centimetres.
Housing is static with respect to ground, when the kiln body rotates, can guarantee that by seal approach housing and the formed cavity 9 of kiln body are in sealing state.
The charging aperture of housing upside connects batcher, treat that pre-thermal material enters in housing and the formed cavity of kiln body from charging aperture, treat that pre-thermal material taken up repeatedly by lifting blade, bringing to the cavity upside constantly raises and spreads, make material form uniform curtain in tube, thermal current abundant and that cavity is interior carries out heat exchange, spreads owing to treating that pre-thermal material is raised repeatedly, contained treats pre-thermal material by preliminary preheating, thereby reaches the purpose of preheating.
Simultaneously, reduced kiln body environment temperature on every side after the waste heat recovery, killed two birds with one stone, saved and added hot water or the required fuel cost of air, investment payback time is short, can obtain the economic well-being of workers and staff of millions of units, real low input, high repayment in service life at waste-heat recovery device.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
