Embodiment 1

[0037] In the description of the technical solution below, a rotary kiln with a diameter of 600 millimeters and a length of 3000 millimeters is used as an example. In fact, a smaller or larger rotary kiln can be built with this method. Building a smaller or larger rotary kiln will inevitably adjust some dimensions mentioned in the technical solution, therefore, the adjustment of the size does not affect the principle of the following technical solution.

[0038] Adopt the following technical solutions:

[0039] 1. Two-layer furnace body is used, wherein the inner furnace body 8 is rotating, while the outer furnace body 9 is fixed, such as figure 2 shown.

[0040] 2. The outer furnace body 9 retains a transmission pipe of tens of millimeters (10mm to 100mm) and extends outward for a certain length, and contains a transmission shaft 6 with a diameter slightly smaller than the pipe (with a difference of 1-10mm). Transmission shaft 6 is rotatable inside the pipeline, and uses t...

Embodiment 2

[0047] A high-pressure rotary furnace, comprising: a furnace body, the furnace body is divided into an outer furnace body 9 and an inner furnace body 8, the outer furnace body 9 is provided with an inner furnace body 8, and the outer furnace body 9 is provided with an outward Extended transmission pipe, the transmission pipe is provided with a transmission shaft 6, one end of the transmission shaft 6 is connected with the internal furnace body 8, and the other end is connected with the driving device 1, and the internal furnace body 8 is connected with the transmission The rotation of the shaft 6 revolves around the central axis of the inner furnace body 8, a seal is provided between the transmission pipe and the transmission shaft 6, and the two ends of the outer furnace body 9 are provided with a feed port 5 and a discharge port 12. Exhaust port 11.

Embodiment 3

[0049] A high-pressure rotary furnace, comprising: a furnace body, the furnace body is divided into an outer furnace body 9 and an inner furnace body 8, the outer furnace body 9 is provided with an inner furnace body 8, and the outer furnace body 9 is provided with an outward Extended transmission pipe, the transmission pipe is provided with a transmission shaft 6, one end of the transmission shaft 6 is connected with the internal furnace body 8, and the other end is connected with the driving device 1, and the internal furnace body 8 is connected with the transmission The rotation of the shaft 6 revolves around the central axis of the inner furnace body 8, a seal is provided between the transmission pipe and the transmission shaft 6, and the two ends of the outer furnace body 9 are provided with a feed port 5 and a discharge port 12. Exhaust port 11.

[0050] In this application, the size of the seal used is reduced by adopting the structure of a two-layer furnace body, which...

Abstract

The invention relates to a high-pressure rotary furnace, comprising: a furnace body, the furnace body is divided into an outer furnace body and an inner furnace body, the outer furnace body is provided with an inner furnace body, and the outer furnace body is provided with an outwardly extending A transmission pipe, a transmission shaft is arranged in the transmission pipe, one end of the transmission shaft is connected with the inner furnace body, and the other end is connected with the driving device, and the inner furnace body rotates around the inner furnace body with the rotation of the transmission shaft The central axis of the furnace rotates, a seal is provided between the transmission pipe and the transmission shaft, and the two ends of the outer furnace body are provided with a feed port, a discharge port and an exhaust port. It can solve the sealing problem of the rotary kiln, increase the internal pressure of the rotary kiln to 200kPa or even higher, and is durable.

Description

technical field [0001] The invention belongs to the field of rotary furnaces, and in particular relates to a high-pressure rotary furnace. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Rotary kiln is a kind of thermal equipment for calcining, roasting or drying granular and powdery materials. As a conventional kiln type, the rotary kiln has existed for hundreds of years, but all of them are large or super large, and are mainly used in the processing of powder or mineral materials. Although the output is large, they all have the disadvantage of being unable to be sealed. [0004] In chemical production, many chemical reactions, especially those containing gas in the raw...
