Abstract
The invention discloses a heat preservation structure for a rotary kiln. The heat preservation structure for the rotary kiln comprises a rotary kiln body sleeved with an outer barrel. The outer barrel is fixedly mounted on the rotary kiln body through bolts. A high-temperature-resisting and heat-insulating layer is arranged on the inner wall of the outer barrel. A sealed cavity is formed between the high-temperature-resisting and heat-insulating layer and the rotary kiln body. The outer barrel is further provided with an air valve communicating with the cavity. The effect of insulation between the rotary kiln body and outside air is good, so that heat transfer media are decreased, it is ensured that most heat in the rotary kiln body is not lost, energy consumption is reduced, and a good working environment is created for workers; besides, the whole installation process of the heat preservation structure is simple, the manufacturing cost is low, and great interests are brought to enterprises.
Description
Technical field
The present invention relates to cement making equipment technical field, particularly relate to a kind of insulation construction for rotary kiln.
Background technology
Rotary kiln is at building materials, metallurgical, chemical industry, in many production industries such as environmental protection, it is widely used revolving drum equipment and solid material is carried out machinery, physical or chemical treatment, in cement making equipment, rotary kiln is requisite, aborning, the temperature of rotary kiln needs to be maintained at 1000 degrees centigrade, owing to rotary kiln is to work in an open environment, therefore there is serious thermal loss, the height enough in order to ensure temperature, energy consumption just increases therewith, production cost increases, and the partial heat lost makes the ambient temperature near rotary kiln be greatly improved, workman is often in a rugged environment work.
Summary of the invention
The purpose of the present invention is that provides a kind of insulation construction for rotary kiln to solve the problems referred to above.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of insulation construction for rotary kiln, including rotary kiln body, described rotary kiln body fits has outer cylinder body, described outer cylinder body is bolted and is installed on described rotary kiln body, described outer cylinder body inwall is provided with high temperature resistant heat insulation layer, forming the cavity of sealing between described high temperature resistant heat insulation layer and described rotary kiln body, described outer cylinder body is additionally provided with the air valve communicated with described cavity.
Specifically, the two ends of described outer cylinder body are provided with resistant to elevated temperatures elastic washer.
Specifically, described high temperature resistant heat insulation layer is calcium-silicate thermal insulation material.
Specifically, described rotary kiln body is provided with bolt block, and described outer cylinder body inwall is provided with projection, described bolt block and described projection and is connected by described bolt.
Specifically, on same loop wire, described bolt block has four, and described projection has four, four described bolt blocks and four described projection one_to_one corresponding.
The beneficial effects of the present invention is:
In the present invention, rotary kiln body is good with the isolation effect of extraneous air, decrease heat transmission medium, ensure that rotary kiln intrinsic overwhelming majority heat will not scatter and disappear, reduce energy consumption, a good working environment has been built for workman, and the installation process of whole insulation construction is simple, cost of manufacture is low, can bring huge interests to enterprise.
Accompanying drawing explanation
Fig. 1 is longitudinal sectional structure schematic diagram of the insulation construction for rotary kiln of the present invention;
Fig. 2 is the insulation construction transverse direction sectional structure schematic diagram for rotary kiln of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
The present invention includes rotary kiln body 6, rotary kiln body 6 is set with outer cylinder body 1, outer cylinder body 1 is fixedly installed on rotary kiln body 6 by bolt 3, outer cylinder body 1 inwall is provided with high temperature resistant heat insulation layer 2, forming the cavity of sealing between high temperature resistant heat insulation layer 2 and rotary kiln body 6, outer cylinder body 1 is additionally provided with the air valve 8 communicated with cavity.
Insulation construction for rotary kiln of the present invention, the two ends of outer cylinder body 1 are provided with resistant to elevated temperatures elastic washer 7, docked between two by multiple outer cylinder bodies 1 and can cover whole rotary kiln body 6, elastic washer 7 is eliminated gap by two adjacent outer cylinder body extruding, ensure that cavity is for sealing structure, high temperature resistant heat insulation layer 2 is calcium-silicate thermal insulation material, this material is developed by University of Science & Technology, Beijing, the high temperature of more than 1000 degrees Celsius can be withstood, rotary kiln body 6 is provided with bolt block 5, outer cylinder body 1 inwall is provided with projection 4, bolt block 5 and projection 4 are connected by bolt 3, this connected mode does not interfere with the operation interval structure of rotary kiln body 6, on same loop wire, bolt block 5 has four, projection 4 has four, four bolt blocks 5 and four projection 4 one_to_one corresponding, make the relative rotary kiln body 6 of outer cylinder body 1 can be totally stationary, noise will not be produced, extend the service life of insulation construction.
Insulation construction for rotary kiln of the present invention, in the process installing back rotary kiln body 6, just outer cylinder body 1 can be mounted above, main docking by multiple outer cylinder bodies 1 forms, after installing, apparatus for vacuum producing is utilized to be extracted out by the most of air in the cavity formed between high temperature resistant heat insulation layer 2 and rotary kiln body 6 from air valve 8, then air valve is shut, so in the process of rotary kiln body 6 work, rotary kiln body 6 is owing to isolating cavity vacuum layer with extraneous air, high temperature resistant heat insulation layer 2 and outer cylinder body 1, decrease heat transmission medium, isolation effect is good, the most heats that ensure that in rotary kiln body 6 will not scatter and disappear, reduce energy consumption, a good working environment has been built for workman, and the installation process of whole insulation construction is simple, cost of manufacture is low, huge interests can be brought to enterprise.
These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included in protection scope of the present invention.
