Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] As shown in the accompanying drawings, a high-speed rotary kiln with controllable atmosphere includes a horizontal box body 9, in which a horizontal rotary furnace body 16 is used, and adjustable support rods 4 are respectively arranged under the two ends of the box body 9, Such as screw rods, etc., or an adjustable support rod 4 is provided under one end of the box body 9, and a fixed support rod 10 is provided at the other end. Manual adjustment of the adjustable support rod 4 can make the angle range between the rotary furnace body 16 and the horizontal plane be -5 °~5°, a transmission device 15 that can drive the furnace body to rotate is set outside the rotary furnace body 16. The transmission device 15 is connected to the motor 14 through the speed change system 13, and is driven by the motor 14. The speed change system 13 realizes...

Abstract

The invention discloses an atmosphere-controllable high-speed rotary kiln, which comprises a horizontal rotary furnace placed in a transverse case. A transmission capable of driving the furnace to rotate is disposed outside the rotary furnace, adjustable struts are respectively arranged under two ends of the case, or an adjustable strut is arranged under one end of the case while a fixed strut is arranged under the other end of the case, so that one end of the rotary furnace can be high while the other end of the rotary furnace is low after the rotary furnace is adjusted according to needs. The adjustable struts are adopted, so that free angle change of a kiln body can be realized, an included angle between the kiln body and the horizontal plane can range from minus 5 degrees to 5 degree, raw materials are reacted sufficiently, simultaneously, the atmosphere-controllable high-speed rotary kiln is provided with a temperature control system capable of fast increasing and reducing the temperature in the furnace, and is further provided with a vacuumizing system, the atmosphere in the furnace is controllable, the rotation speed of the rotary kiln is high, so that a material calcination effect is fine, and effects of energy conservation, high efficiency and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of rotary kilns, and relates to a test rotary kiln capable of rapid heating and cooling used in calcium carbonate decomposition and capture or cement production, in particular to a high-speed rotary kiln with controllable atmosphere. Background technique [0002] Rotary kiln is the main equipment for calcination of bulk materials in the production of metallurgy, chemical industry, cement and other industries, and generally works under negative pressure. In the process of production and operation, the material advances slowly with the inclination and rotary motion of the cylinder itself, so as to achieve the purpose of mechanical, physical or chemical treatment of solid materials. The existing test rotary kiln lacks a temperature control device for quickly raising and lowering the temperature in the kiln, and the rotation speed is relatively slow, and the angle between the kiln body and the horizontal plane i...
