Description

Technical Field

[0001] This utility model relates to the technical field of bell-type furnace equipment, and in particular to a bell-type integrated furnace for thin material annealing. Background Technology

[0002] Bell-type bright annealing furnaces are periodic heat treatment furnaces used for recrystallization bright annealing of steel coils under a protective atmosphere. They are widely used in metal processing, electronic components, ceramic materials and other fields. Existing bell-type furnaces have a single furnace body structure, and in order to increase production capacity, the number of stacked coils inside the furnace body is relatively high. However, the coils are relatively thin, and the coils located at the bottom of the furnace body are subjected to greater pressure. As a result, after being heated at high temperatures in the furnace body, the hardness of the coils decreases, and the coils located at the bottom of the furnace body are prone to sticking due to excessive pressure. Therefore, it is necessary to design a new bell-type furnace structure to solve the above problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a bell-type integrated furnace for thin material annealing, wherein the furnace body is provided with two heating chambers and a heating inner shroud is provided in the two heating chambers. This can maintain the production capacity and reduce the number of material roll stacking layers in the heating inner shroud, thereby reducing the pressure on the material roll located at the bottom of the heating inner shroud, so as to prevent the material roll located at the bottom of the heating inner shroud from being subjected to excessive pressure and sticking.

[0004] A bell-type integrated furnace for annealing thin materials includes a furnace body with two heating chambers inside. A furnace base is provided on the bottom surface of the furnace body at the positions of the two heating chambers. A heating inner cover extending into the heating chamber is provided on the furnace base. A fan is provided inside the furnace base, and multiple convection plates are provided inside the heating inner cover.

[0006] Preferably, a heat exchanger is provided on the top of the side wall of the furnace body, the heat exchanger is connected to the heating chamber through a gas delivery pipe, and multiple heat exchange tubes are provided inside the heat exchanger.

[0007] Preferably, the top surface of the furnace base is provided with a furnace platform, and the furnace base is provided with a receiving cavity below the furnace platform, and multiple guide plates are provided at intervals around the furnace platform.

[0008] Preferably, a plurality of convection plates are arranged from top to bottom inside the heating inner shroud, and a convection opening is provided at the center of each convection plate.

[0009] The beneficial effects of this utility model are: the bell-type integrated furnace for thin material annealing is designed so that the furnace body and the heating chamber cooperate with each other, so that the furnace body is provided with two heating chambers, and the two heating chambers are provided with heating inner covers. This can maintain the production capacity and reduce the number of material roll stacking layers in the heating inner cover, thereby reducing the pressure on the material rolls located under the heating inner cover, so as to prevent the material rolls located under the heating inner cover from being subjected to excessive pressure and sticking.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0015] like Figures 1 to 3 As shown, a bell-type integrated furnace for thin material annealing includes a furnace body 1, two heating chambers 2 are provided inside the furnace body 1, and a furnace base 3 is provided on the bottom surface of the furnace body 1 at the positions of the two heating chambers 2. A heating inner cover 4 extending into the heating chambers 2 is provided on the furnace base 3. A fan 5 is provided inside the furnace base 3, and multiple convection plates 6 are provided inside the heating inner cover 4.

[0016] The working principle of the bell-type integrated furnace for thin-film annealing described in this utility model is achieved through the cooperation of the furnace body 1 and the heating chamber 2. Figures 1 to 3 As shown, the furnace body 1 is provided with two heating chambers 2, and the two heating chambers 2 are provided with heating inner covers 4. This can maintain the production capacity and reduce the number of material roll stacking layers in the heating inner cover 4, thereby reducing the pressure on the material rolls located under the heating inner cover 4. Compared with the traditional bell-type furnace, this bell-type integrated furnace for thin material annealing can maintain the production capacity while avoiding the material rolls located under the heating inner cover 4 from being subjected to excessive pressure and sticking.

[0017] Specifically, the side wall of the furnace body 1 is provided with multiple heating nozzles 7 extending into the heating chamber 2, and the multiple heating nozzles 7 are connected by an annular pipe 8. A heat exchanger 9 is provided at the top of the side wall of the furnace body 1, and the heat exchanger 9 is connected to the heating chamber 2 via a gas delivery pipe. The heat exchanger 9 contains multiple heat exchange tubes 10, such as... Figures 1 to 3 As shown, multiple heating nozzles 7 are connected by an annular pipe 8 and can be connected to an external electrical control cabinet (not shown in the figure) for unified control. The heating nozzles 7 heat the material in the heating chamber 2. The blower 5 can be a blower 5. The operation of the blower 5 creates an airflow to heat the material roll inside the heating inner cover 4. The exhaust gas generated when the heating nozzles 7 are heating can move along the conveying air pipe to the heat exchanger 9. The inner heat exchange tube 10 of the heat exchanger 9 can recover the waste heat of the exhaust gas and improve the heat utilization rate.

[0018] Furthermore, a furnace platform 11 is provided on the top surface of the furnace base 3, and a receiving cavity 12 is provided below the furnace platform 11 in the furnace base 3. Multiple guide plates 13 are spaced around the furnace platform 11. Even further, multiple convection plates 6 are arranged from top to bottom inside the heating inner shroud 4, and a convection opening 14 is provided at the center of each convection plate 6. Figures 1 to 3 As shown, the accommodating cavity 12 and the furnace platform 11 facilitate the installation of the blower 5. The blower 5 generates an upward airflow at the bottom center of the heating inner cover 4. The convection opening 14 of the convection plate 6 facilitates the airflow to be transported to the bottom of the heating inner cover 4, and then flows downward along the inner periphery of the heating inner cover 4 to the guide plate 13, thereby forming a heating circulation and improving the heating efficiency of the coil.

[0019] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
