Technical Field

[0001] This utility model relates to the field of annealing furnaces, and in particular to an energy-saving bell-type annealing furnace. Background Technology

[0002] Annealing furnaces are used to anneal various metal materials to improve their properties, such as enhancing the mechanical properties of stainless steel, reducing hardness, and improving plasticity and toughness, in order to meet different processing and usage requirements. However, existing annealing furnaces have long heating processes, require long preheating times, and it is difficult to recover the preheating energy used in the annealing furnace, resulting in wasted energy and increased production costs.

[0003] Therefore, it is necessary to provide an energy-saving bell-type annealing furnace to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides an energy-saving bell-type annealing furnace, which solves the problems of existing annealing furnaces having long heating processes, requiring long preheating times, and being difficult to recover the preheating energy, thus wasting energy and increasing production costs.

[0005] To solve the above-mentioned technical problems, this utility model provides an energy-saving bell-type annealing furnace, including an annealing furnace body and a heat storage tank. The annealing furnace body is provided with a feeding door and an operation panel.

The coil interfaces are connected to the heat storage tank via connecting pipes. The heat storage tank has a water inlet and a water outlet at the center of its bottom. A rotating motor is screwed to the center of the top of the heat storage tank via a motor mounting bracket. A stirring blade is welded to the top inner side of the heat storage tank, and the rotating motor is connected to the stirring blade via a rotating connecting shaft.

[0012] Compared with related technologies, the energy-saving bell-type annealing furnace equipment provided by this utility model has the following beneficial effects:

[0013] This utility model provides an energy-saving bell-type annealing furnace. A pump drives circulating water through heat exchange tubes to preheat the furnace body before operation and remove residual heat after operation. By turning on the power supply to the rotating motor, the motor drives the stirring blades via a rotating connecting shaft. Simultaneously, heat is exchanged between the water in the heat storage tank and the coil. This solves the problems of existing annealing furnaces, such as long heating processes, requiring extended preheating times, difficulty in recovering preheated water, wasted energy, and increased production costs.
