a rotary furnace

Abstract

The application discloses a rotary kiln, which includes a drum, the feed end of the drum is higher than the discharge end of the drum, and also includes: a feed device, which is in rotational and sealed communication with the feed end of the drum; a discharge device, which is connected with the discharge end of the drum The material end is rotated and sealed; the driving device is arranged outside the drum to drive the drum to reciprocate and swing around its rotation axis; the supporting device is installed outside the drum to rotate the supporting drum; the control device is connected to the driving device through wires , used to control the radian of the reciprocating swing of the drum. Since the drum only swings within a certain arc and does not rotate in a single direction, devices or pipes for process treatment can be installed on the outer wall of the drum without restricting the swing of the drum, which is more conducive to the heating, cooling, and cooling of materials. Reactions etc.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a rotary kiln. Background technique [0002] Energy exists in nature in various forms. For some unconventional solid materials, such as garbage, sludge, biomass, inorganic compounds, low-rank coal, oil shale, oil sludge, etc., the utilization rate of human beings is not high at present. By heating, cooling, and reacting these unconventional solid materials, they can be converted into energy and materials for people to use. With the increasing shortage of energy, the use of unconventional materials for energy and material conversion has been widely used by people in the industry. focus. [0003] The conversion process of the above materials often needs to go through pyrolysis, gasification, carbonization, activation, reaction, cooling and other processes, and these processes are generally carried out by rotary kilns. The existing rotary furnace usually consists of a d...

AI Technical Summary

Problems solved by technology

Because the drum of the existing rotary furnace rotates continuously, and the sealing surface between the two ends of the drum and the furnace head and the furnace tail is relatively large, therefore, the sealing between the drum and the furnace head and the furnace tail is difficult, and the air leakage rate is high, especially when working at a higher temperature. Due to the thermal expansion and contraction of the furnace body and the limitation of high-temperature dynamic sealing materials, the sealing effect is very poor, which has a great impact on the production process; in addition, due to the continuous rotation of the drum, it is impossible to install other devices on the outer peripheral wall of the drum. The process reaction device, because other devices need to be connected to external equipment through wires or pipes, can only be installed at the furnace head and furnace tail, resulting in that the internal process of the drum cannot be effectively completed, and the outer wall of the drum cannot be connected with external pipes, and fluid materials cannot be directly from the furnace. The outer wall of the drum can only enter and exit at the furnace head and furnace tail, which is not conducive to the control of the material in the middle position of the rotary furnace

The above factors are not conducive to the handling of materials

[0004] In summary, how to solve the problem that the poor sealing of the rotary furnace and the inability to install a device for process reaction on the outer peripheral wall of the drum, resulting in the inability to effectively complete the material treatment process, has become an urgent problem to be solved by those skilled in the art
