Rotary furnace

Abstract

The invention discloses a rotary furnace. The rotary furnace comprises a roller, and the feeding end of the roller is higher than the discharging end of the roller; the rotary furnace further comprises a feeding device, a discharging device, a driving device, a supporting device and a control device, wherein the feeding device communicates with the feeding end of the roller in a rotating and sealed manner, the discharging device communicates with the discharging end of the roller in a rotating and sealed manner, the driving device is arranged outside the roller and used for driving the roller to swing in a reciprocating manner around the rotation axis of the roller, the supporting device is arranged outside the roller and used for supporting roller in a rotating manner, and the control device is connected with the driving device through a wire and used for controlling the reciprocating swing radian of the roller. Due to the fact that the roller only swings within certain radian and does not rotate in the single direction, a device or a pipeline used for technological treatment can be arranged on the outer wall of the roller, swing of the roller cannot be limited, and treatments such as heating, cooling and reacting of materials are better promoted.

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
