[0002] Hot shear furnaces mainly include heating furnaces and hot shears. The heating furnaces are mainly used to heat long rod-shaped metals, and the hot shears shear the heated metals into specific lengths. Hot shear furnaces are usually divided into two types: single-rod hot shear furnaces and multi-rod hot shear furnaces. They may differ slightly in structure and function, but their basic working principles are similar.

When the flue gas is discharged from the heating furnace, it will carry a lot of heat, causing heat loss in the heating furnace, thereby increasing the energy consumption of the heating furnace, which is not conducive to the energy saving and environmental protection of the heating furnace. Therefore, an energy-saving hot shear furnace is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] See also Figure 1 An energy-saving hot shear furnace in this embodiment includes a support frame 1, on which a plurality of heating chambers 11 are arranged, and a heating roller 111 is arranged in the heating chamber 11, and the heating roller 111 is used to heat the metal. A circulation chamber 12 is arranged on the left side of the heating chamber 11, and a circulation chamber 12 is arranged on the right side of the heating chamber 11; by arranging the heating roller 111 in the heating chamber 11, the heating effect of the inside of the heating chamber 11 can be effectively achieved during the use, so that the metal inside the heating chamber 11 can be heated to ensure its use effect.

[0023] The top of the circulation bin 12 is connected with a connecting pipe 15, the other end of the connecting pipe 15 is fixedly connected with the heat recovery component 2, the heat recovery component 2 is connected with the connecting pipe 15, the bottom of the heat recovery component 2 is provided with a preheating bin 16, the preheating bin 16 is connected with the heat recovery component 2, the right side of the preheating bin 16 is connected with a feeding port 17, and the feeding port 17 is provided with a sealing door 18. This connection method can effectively achieve the effect of heat recovery during use.

[0024] As a preferred technical solution in this embodiment, in actual use, the staff can first control the exhaust bin 13 to discharge the flue gas required to be discharged in the heating bin 11 into the heat recovery component 2 through the connecting pipe 15, and then enter the preheating bin 16 under the action of the heat recovery component 2. Since the preheating bin 16 and the feeding port 17 remain connected, the exhausted flue gas can effectively increase the temperature in the feeding port 17 and the preheating bin 16. When a batch of metals is being heated, the staff can put another batch of metals into the feeding port 17 and the preheating bin 16 to preheat them. This arrangement can effectively achieve the effect of recovering heat energy during use, thereby ensuring that the metal to be heated has a certain stability when it enters the heating bin 11, so that when the heating roller 111 heats it, the metal can be heated to the required temperature quickly, reducing the heating time and reducing energy loss.

[0025] Embodiment 2:

[0026] See also Figure 2-4In order to achieve the effect of preheating the metal, a circulating fan 121 is provided on the top of the circulation bin 12 in this embodiment, and a plurality of air outlets 122 are provided on the circulation bin 12. A feed port 131 is provided on the discharge bin 13, and a transmission belt 132 is provided in the feed port 131, and the other end of the transmission belt 132 extends into the feeding port 17. A heat recovery bin 21 is provided on the heat recovery component 2, and the heat recovery bin 21 is connected to the connecting pipe 15. A connecting cover 23 is provided at the bottom of the heat recovery bin 21, and the connecting cover 23 is connected to the preheating bin 16. An exhaust fan 22 is provided in the heat recovery bin 21. By providing the exhaust fan 22, it can effectively realize the effect of preheating the metal to be heated by sending the flue gas into the preheating bin 16 and the feeding port 17 during use. Further, in the actual use process, the staff can set an activated carbon filter in the heat recovery bin 21 to achieve the effect of absorbing particulate matter and harmful gases in the flue gas.

[0027] It is worth noting that the exhaust fan 22 in this embodiment should be made of high temperature resistant materials, such as metal, to avoid damage due to high temperature during use.

[0028] As a preferred technical solution in this embodiment, in actual use, the staff can control the negative pressure fan 133 to generate negative pressure, so that the smoke required to be discharged from the heating chamber 11 can be drawn into the discharge chamber 13, and then the staff can control the exhaust fan 22 to drive the smoke in the circulation chamber 12 to flow into the heat recovery chamber 21, and then enter the preheating chamber 16 and the feeding port 17 through the connecting hood 23 to achieve the effect of preheating the metal.

[0029] The working principle of the above embodiment is:

[0030] 1. The staff can first control the negative pressure fan 133 to generate negative pressure, so that it can draw the smoke required to be discharged from the heating chamber 11 into the discharge chamber 13, and then the staff can control the exhaust fan 22 to drive the smoke in the circulation chamber 12 to circulate in the heat recovery chamber 21, and then enter the preheating chamber 16 through the connecting cover 23. Because the preheating chamber 16 and the feeding port 17 are connected, the discharged smoke can effectively increase the temperature in the feeding port 17 and the preheating chamber 16. When a batch of metals is being heated, the staff can put another batch of metals into the feeding port 17 and the preheating chamber 16 to preheat them. This arrangement can effectively achieve the effect of recovering heat energy during use, thereby ensuring that when the metal to be heated enters the heating chamber 11, it has a certain stability, so that when the heating roller 111 heats it, it can quickly heat the metal to the required temperature, reducing the heating time and reducing the energy loss.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
