Description

Technical Field

[0001] This utility model relates to the field of quenching furnace technology, specifically a safe quenching furnace. Background Technology

[0002] A quenching furnace is a specialized device for heating workpieces before quenching. Quenching involves placing the workpiece in the furnace and heating it to a quenching temperature above the critical point and holding it for a period of time. Then, the workpiece is quickly removed from the furnace and placed in a quenching liquid (oil or water) for quenching. The quenching furnace heats the workpiece to the required temperature using different heating methods (such as electric heating, gas heating, or oil heating) and then performs the quenching treatment.

[0003] Existing gear manufacturing processes require the use of quenching furnaces. However, during actual use, when removing gears from the furnace, the pliers often cause debris to fall as they are dragged outwards. Furthermore, the pliers are prone to slipping when moving the gear out of the furnace, resulting in hot debris flying everywhere and potentially injuring nearby workers. Therefore, we propose a safer quenching furnace. Utility Model Content

[0004] The purpose of this invention is to provide a safe quenching furnace, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safe quenching furnace, comprising a furnace body, wherein the furnace body is fixed to the top of a platform, and the platform is fixed to the top of a base;

[0006] A receiving plate is fixed to the lower side of the furnace opening of the furnace body, and a smoke collection hood is fixed to the upper side of one side wall of the receiving plate. An exhaust fan and a filter box are fixed to one side of the top of the base. One end of the exhaust fan is connected to the side wall of the filter box through a first conduit, and the top of the filter box is connected to the smoke collection hood through a second conduit.

[0007] By adopting the above technical solution, water is first introduced into the inner cavity of the receiving plate. When the gears that grip the inner cavity of the furnace are dragged outward, if the gears slip, they will fall directly into the inner cavity of the receiving plate and be submerged in water, thus preventing debris from splashing. If the gears do not fall off, the debris falls into the inner cavity of the receiving plate and is cooled by the water, also preventing debris from splashing, thus improving safety. At the same time, the debris or gears falling into the water generate smoke. Starting the exhaust fan can create negative pressure in the smoke collection hood, which can then draw the smoke into the filter box for filtration, thus helping to prevent the smoke from harming the surrounding personnel.

[0008] In a preferred embodiment of this utility model, the outer wall of the furnace body is provided with a furnace door, and an electric push rod is fixed to the top of the furnace body. The outer end of the electric push rod is fixedly connected to the upper side of one side wall of the furnace door through a connecting plate.

[0009] By adopting the technical scheme, the electric push rod can drive the furnace door to lift, so that the furnace mouth of the furnace body is opened and closed, and the workpiece is taken out and placed.

[0010] As a preferred embodiment of the utility model, the outer wall of the furnace body is provided with a limiting sliding groove on both sides, the limiting sliding groove is provided with a limiting sliding block matched in the inner cavity, and the outer wall of the limiting sliding block is fixedly connected with the furnace door.

[0011] By adopting the technical scheme, the limiting sliding block slides in the limiting sliding groove, so that the stability of the furnace door lifting is improved.

[0012] As a preferred embodiment of the utility model, the inner cavity of the filter box is fixed with an activated carbon filter screen plate.

[0013] By adopting the technical scheme, the activated carbon filter screen plate can remove harmful molecules in the smoke, so that the effect of filtering the gas is achieved.

[0014] As a preferred embodiment of the utility model, the side wall of the receiving disc is fixedly connected with a drain valve at the lower side.

[0015] By adopting the technical scheme, the drain valve is arranged, so that the used water can be discharged.

[0016] Compared with the prior art, the utility model has the beneficial effects as follows:

[0017] The safety quenching furnace has the advantages that the receiving disc is fixed on the front side of the furnace body, water is introduced into the receiving disc, so that when the gear is taken out, the gear can be received by the receiving disc when the gear slips off, and the gear is cooled by the water, so that the debris falling off and the gear directly falling off to splash the debris to cause harm to the surrounding workers are avoided;

[0018] The exhaust fan can generate negative pressure in the smoke hood, so that the harmful gas generated after the debris falls into the water can be absorbed, and then filtered through the filter box, so that the harmful gas is removed, and the harm of the gas to the respiratory tract of the surrounding workers is avoided.
