Description

Technical Field

[0001] The utility model relates to the technical field of steel billet waste heat recovery, in particular to a steel billet waste heat recovery device. Background Art

[0002] my country is a major producer of metals such as steel, copper, aluminum, gold and silver. Roller table is the main equipment for transporting rolled pieces in metal smelting workshops. Under normal circumstances, the temperature of the steel billets on the roller table can reach over 1000°C. The steel billets on the roller table are exposed to the air environment and lose a large amount of radiant heat into the air environment. In addition, the radiant heat of solids is difficult to recover.

[0003] In the related art, the waste heat recovery device uses cold air to contact the steel billet, uses the cold air to exchange heat with the steel billet, and guides the heat lost in the air to the hot air output channel through the heat absorption component or the heat preservation cover to recover the waste heat. However, using cold air to exchange heat with the steel billet will cause the heat in the air to be lost too quickly and easily diffuse to the surroundings, making it difficult to fully recover the heat, and the recovery efficiency is limited. In addition, it will still cause heat radiation to the surrounding environment to a certain extent, and the safety and comfort of the working environment cannot be guaranteed. Utility Model Content

[0004] The purpose of the utility model is to provide a steel billet waste heat recovery device to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] The billet waste heat recovery device according to this solution has at least the following technical effects:

[0011] The steel billet waste heat recovery device arranges a radiator group on the top wall and both side walls of the shell, and inserts the steel billet conveying device into the hollow cavity of the waste heat recovery device, so that the waste heat generated by the steel billet can be effectively captured, and the waste heat can be fully recovered and used as the thermal energy required for other processes, thereby reducing energy consumption, saving production costs and achieving energy conservation and emission reduction; at the same time, it can prevent the heat radiation of the steel billet from being dissipated to the surrounding environment, reduce the working environment temperature in the factory building, and ensure the safety and comfort of the working environment.

[0012] As a further solution of the utility model: the radiator group is divided into a zone A radiator group and a zone B radiator group. The zone A radiator group and the zone B radiator group are arranged in a mirror-symmetrical manner, both are arranged in an inverted "L" shape, and extend from the top wall to the side walls on both sides.

[0013] Since the radiator group is divided into a zone A radiator group and a zone B radiator group, and both are arranged in an inverted "L" shape, the zone A radiator group and the zone B radiator group are arranged in a mirror-symmetrical manner and extend from the top wall to the side walls on both sides, so that the radiator group effectively covers the billet conveying device, which is more conducive to capturing the waste heat generated by the billet, improving the heat exchange rate between the radiator group and the waste heat of the billet, thereby improving the waste heat recovery efficiency of the waste heat recovery device.

[0022] As a further solution of the utility model: the heat medium main pipes of the radiator group in zone A and the radiator group in zone B are respectively connected with heat transfer oil pipes.

[0023] Since the heat medium main pipes of the radiator group in area A and the radiator group in area B are respectively connected with heat transfer oil pipes, the heat transfer oil in the heat transfer oil pipes can better conduct the absorbed waste heat, and the heat transfer oil can be used as a storage medium for the heat energy required for other processes, thereby improving energy utilization efficiency.

[0024] As a further solution of the utility model: a motor is arranged at the bottom of one side of the steel billet conveying device, and the motor is connected to a roller via an output shaft.

[0025] Since a motor is arranged at the bottom of one side of the billet conveying device, and the motor is connected to a roller through an output shaft, the billet moves on the roller at a faster speed. Especially when a large number of billets need to be conveyed continuously, automatic conveying can be realized, manual operation can be reduced, and conveying efficiency can be improved.

[0026] As a further solution of the utility model: a heat-resistant layer is further provided between the top wall and the side wall and the radiator assembly.

[0027] Since a heat-resistant layer is provided between the top wall and the side wall and the radiator group, the heat transfer between the radiator group and the surrounding environment can be effectively isolated, the loss of heat energy is reduced, the heat transfer efficiency of the radiator group is improved, the temperature stability in the waste heat recovery device is ensured, and the stability and efficiency of waste heat recovery are further improved.
