Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a circulating cooling furnace. Background Art

[0002] Heat treatment refers to a metal hot processing technology that uses heating, heat preservation and cooling to obtain the expected structure and performance of materials in the solid state. After heating, the workpiece needs to be cooled, and traditional cooling furnaces mostly use a single-stroke cooling method. This treatment method is more complicated during loading and unloading. It is necessary to manually remove the material plate and then send it to the cooling feed end for subsequent re-cooling treatment, resulting in low cooling efficiency and high cost. In addition, the conveyor belt will continue to run during the transportation process, which requires workers to constantly remove the material plate without interruption, and it is impossible to work efficiently for a long time. Therefore, a circulating cooling furnace is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a circulating cooling furnace for solving the problem of low efficiency in avoiding manual transportation of material plates in the prior art.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] A circulating cooling furnace, comprising:

[0006] A cooling furnace, wherein a cooling fan is arranged on one side of the cooling furnace, a cold air inlet is arranged on the side wall of the cooling furnace, and a cold air output end of the cooling fan is connected to the cold air inlet;

[0007] A circulating cooling line is arranged in a cooling furnace. The circulating cooling line includes two groups of cooling racks and one group of circulating racks which are arranged in sequence from top to bottom in the cooling furnace. Conveying chains are arranged on the two groups of cooling racks. A circulating chain is arranged on the circulating rack. The conveying direction of the circulating chain is opposite to that of the conveying direction of the conveying chain.

[0008] To implement the above technical solution, by setting the cold air output end of the cold air fan to be connected to the cold air inlet, the cold air fan can be used to provide a continuous cooling source for the cooling furnace to ensure the cooling effect. The conveying chains on the two groups of cooling racks are arranged in the opposite direction of the circulating chains on the circulating racks. The material tray after cooling on the conveying chain can be taken down and directly placed on the circulating chain, and the circulating chain will re-convey the material tray to the feeding end of the cooling furnace, thereby improving the working efficiency of the cooling cycle.

[0009] In one embodiment of the utility model, a cooling bellows is arranged inside the cooling furnace, and the cooling bellows are symmetrically arranged along both sides of the conveying chain. The cooling bellows on one side are connected to the cold air inlet, and the cooling bellows are arranged at intervals between the two sides of the conveying chain.

[0010] To implement the above technical solution, by connecting the cooling bellows on one side to the cold air inlet, cold air can be continuously delivered to the conveying space of the conveyor chain, thereby ensuring the cooling effect on the materials that need to be cooled on the conveyor chain. The symmetrically arranged cooling bellows can blow the cold air input by the cooling bellows connected to one side of the cold air inlet back into the conveying space of the conveyor chain, thereby ensuring the cooling effect and reducing energy loss.

[0011] In one embodiment of the present invention, a limiter group is provided at the end of the travel of the conveying chain and the circulating chain to prevent the material plate from falling from the conveying chain.

[0012] To implement the above technical solution, limit groups are set at the ends of the travel of the conveying chain and the circulating chain. During the conveying process, the limit groups can be used to block the material plate. On the one hand, it can prevent the material plate from falling, and on the other hand, it can facilitate manual operation to remove the material on the material plate. It is a more humane way of taking materials and avoids excessive fatigue of workers.

[0013] In one embodiment of the utility model, the limiting group includes a blocking base detachably connected to the cooling rack or the circulation rack at both ends, and two groups of horizontal blockers are arranged on the blocking base, and each group of two blocking bases.

[0014] To implement the above technical solution, a blocking base is detachably connected to the cooling rack or the circulation rack at both ends, and two groups of horizontal blockers are arranged on the blocking base. This makes it possible to block the material plates at the ends of the travel of the conveyor chain and the circulation chain. By grouping the blocking bases into groups of two, it is possible to prevent the material plates that need to be removed from being blocked by the accumulation of subsequent material plates, thereby affecting the convenience of removing the material plates.

[0015] In one embodiment of the utility model, sprocket guide rails are provided on the cooling rack and the circulation rack, and the outer sides of the sprocket guide rails are provided with limiting guide plates extending upward from the sprocket guide rails.

[0016] To implement the above technical solution, the setting of the limiting guide plate can play a guiding and limiting role in the conveying of the material plate, thereby ensuring the conveying stability of the material plate on the cooling rack and the circulation rack.

[0017] In one embodiment of the present invention, an exhaust pipe is disposed on the top of the cooling furnace.

[0018] To implement the above technical solution, the setting of the exhaust pipe can facilitate the timely discharge of heat generated in the cooling furnace, avoiding accumulation in the cooling furnace and affecting the subsequent cooling effect.

[0019] As described above, a circulating cooling furnace of the utility model has the following beneficial effects: by connecting the cold air output end of the cold air blower to the cold air inlet, the cold air blower can be used to provide a continuous cooling source for the cooling furnace to ensure the cooling effect, and the two sets of cooling racks are provided with conveying chains and the conveying directions of the circulating chains on the circulating racks are arranged in opposite directions, so that the material tray after cooling on the conveying chain can be taken down and directly placed on the circulating chain, and the material tray can be re-conveyed to the feeding end of the cooling furnace by the circulating chain, thereby improving the working efficiency of the cooling cycle.
