Technical Field

[0001] The utility model belongs to the technical field of triple furnaces, and particularly relates to a triple furnace structure for waste heat recovery. Background Technique

[0002] The triple furnace is one of the most common and important equipment in metal smelting. Its process system is a hot triple furnace continuous copper smelting production system of oxygen-enriched side-blown bath smelting + multi-gun top-blown continuous blowing + pyrometallurgical anode refining. When the triple furnace is working, it requires a large amount of thermal resources to ensure the stability and continuity of the smelting temperature.

[0003] For the existing triple furnace used in metal smelting, when it is working, it consumes a large amount of thermal resources, and a part of the thermal resources will dissipate to the external environment through the furnace body of the triple furnace, and thus the problem of waste of the dissipated thermal resources occurs; in addition, the furnace bodies of the triple furnace are connected to each other through connecting pipes, and the furnace body and the connecting pipes are connected by flange plates, so the disassembly and assembly are relatively difficult. Therefore, we provide a triple furnace structure for waste heat recovery to solve the problems that occur above. Summary of the Utility Model

By using a connecting component, it is convenient to install the connecting pipes between the furnace bodies of the triple furnace thereon, and the disassembly and assembly method is simple and easy. By using a waste heat recovery component, the waste heat emitted from the furnace body can be recovered and transported to other production lines, solving the problems that occur in the existing triple furnace used in metal smelting.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a triple furnace structure for waste heat recovery, including a furnace body.

[0031] Specifically, plate grooves 201a are provided at both shaft ends of the carrier plate 201 in the connection assembly 2, and a rotating rod 202 and an insert rod 203 are respectively inserted into the two plate grooves 201a. The carrier plate 201 is connected to both shaft ends of the clamping plate 204 through the rotating rod 202 and the insert rod 203. And inner grooves 201b are provided on the inner walls of both the carrier plate 201 and the clamping plate 204. A contact member 205 is also provided in the inner groove 201b.

[0032] Furthermore, a furnace cover 101 is provided on the top of the furnace body 1, and furnace tubes 102 are also provided on the outer wall of the furnace body 1 of the triple furnace. The furnace tubes 102 are connected to the connector 301 of the connection pipe 3 through the connection assembly 2.

The heat concentrated in the waste heat recovery component 5 is output to other production lines by using the output pipe 505.

[0038] The operation process of this embodiment is as follows: When the furnace body 1 of the triple furnace is working, there will be a great deal of heat inside it, and this part of the heat will be transferred to the furnace body 1 and dissipated to the external environment through the furnace body 1. At this time, the heat exchange pipe 401 in the waste heat recovery component 5 will exchange this part of the heat dissipated from the furnace body 1, and the exchanged heat is output through the heat recovery pipe 503, the output pipe 504, and the output pipe 505.
