Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, and more specifically, to a decentralized reversing controlled heating furnace. Background Art

[0002] A heating furnace is a device used to heat materials or workpieces (typically metal) to rolling or forging temperatures. A decentralized reversing control heating furnace uses a reversing valve to achieve alternating air and gas flows, effectively recovering and utilizing heat energy. By periodically switching the flow of air and gas, the heat storage element within the heating furnace continuously cycles through heat storage and release, achieving precise control of the furnace temperature.

[0003] When the existing heating furnace is in use, the high-temperature flue gas undergoes heat exchange in the heat storage chamber, and the heat in the flue gas is absorbed and stored by the heat storage body. However, the high-temperature flue gas contains a large amount of dust, which easily adheres to the heat storage body, thereby affecting the ventilation effect of the heat storage body. It is inconvenient to clean the dust adhered to the heat storage body, and the use effect is poor. Utility Model Content

Similarly, the two heat storage bodies are installed, and the pressure rod squeezes the two heat storage bodies.

[0008] Furthermore, sealing gaskets are movably provided on the two box covers, and the outer sides of the two sealing gaskets are in contact with the two heat storage boxes respectively.

[0009] It can be seen that in the above technical solution, the sealing between the box cover and the heat storage box is improved.

[0010] Furthermore, a material guide plate is movably provided at the bottom of the two filter plates, and the two material guide plates are respectively fixedly installed inside the two heat storage boxes.

[0011] It can be seen that in the above technical solution, the dust is conveniently guided and moved to one side of the interior of the heat storage tank.

[0012] Furthermore, threaded pistons are movably provided on opposite sides of the two guide plates, and the two threaded pistons are respectively threadedly connected to the two heat storage tanks.

[0018] 1. The utility model filters the dust in the high-temperature flue gas through the filter plate. The filtered high-temperature flue gas enters the two heat storage bodies. The motor working shaft rotates, thereby driving the brush plate to rotate. The bristles on the brush plate clean the dust adhering to the bottom of the filter plate.
