Description

Technical Field

[0001] This utility model relates to the field of nitriding furnace technology, and in particular to a continuous nitriding furnace. Background Technology

[0002] Existing nitriding furnaces are large in size and are generally three-dimensional, making it inconvenient to put in and take out materials. After processing, the gas is consumed too quickly during the material removal process, resulting in excessive waste of resources.

[0003] The existing publication number CN214529213U discloses a horizontal high-pressure continuous vacuum nitriding furnace, including a shell, supporting feet, an observation window, a material conveying device, and a gas processing device. The shell has fixing rings at both ends, with supporting feet at the bottom of the fixing rings. The gas processing device is located at the bottom and left end of the shell. By incorporating a furnace door, nitriding furnace device, and shell, the device reduces resource waste both before and after use. A second push rod is located at the right end of the auxiliary pushing device. Pulling the second push rod pulls out the auxiliary pushing device inside the nitriding furnace device, allowing material to be placed in and pushing the second push rod into the nitriding furnace device for nitriding. This process reduces the device's contact with the outside environment, significantly reducing gas leakage. The gas filling device is only connected to the nitriding furnace device, reducing the required space and ensuring full utilization of the gas, effectively reducing resource waste and making it more suitable for widespread use.

[0004] However, when the above-mentioned horizontal high-pressure continuous vacuum nitriding furnace is in use, even though an inner cavity is set inside the furnace to protect the materials and gases, gas still leaks out of the inner cavity during the process of putting the materials in and taking them out. Utility Model Content

[0005] The purpose of this utility model is to provide a continuous nitriding furnace, which solves the problem that when a horizontal high-pressure continuous vacuum nitriding furnace is used, gas still leaks from the furnace during the process of putting the material in and taking it out, even though an inner cavity is set inside the furnace to protect the material and gas.

[0006] To achieve the above objectives, this utility model provides a continuous nitriding furnace, including a furnace body, a protective component, a sealing component, a processing component, and an auxiliary component. The protective component includes an inner cavity, a support frame, a support spring, a protective plug, and an inner sealing strip. The inner cavity is slidably connected to the furnace body and located inside the furnace body. The support frame is fixedly connected to the inner cavity and located inside the inner cavity. The support spring is fixedly connected to the support frame and located outside the support frame. The protective plug is fixedly connected to the support spring and located between the support spring and the inner cavity. The inner sealing strip is fixedly connected to the protective plug and located between the protective plug and the inner cavity. The sealing component, the processing component, and the auxiliary component are respectively connected to the furnace body.

[0007] The sealing assembly includes a sealing cover and an outer sealing strip. The sealing cover is detachably connected to the inner cavity and is located on the outside of the furnace body. The outer sealing strip is fixedly connected to the sealing cover and is located between the sealing cover and the furnace body.

[0008] The sealing assembly further includes a latch and a pull rod. There are multiple latches, each of which is fixedly connected to the sealing cover and located on the outside of the sealing cover. The pull rod is fixedly connected to the sealing cover and located on the outside of the sealing cover.

[0009] The processing components include an air pump, a vacuum pump, and an air compressor. The air pump is fixedly connected to the furnace body and located at the top of the furnace body. The vacuum pump is fixedly connected to the furnace body and located at the bottom of the furnace body. The air compressor is fixedly connected to the furnace body and located at the bottom of the furnace body.

[0010] The auxiliary components include support shafts and top rods. There are multiple support shafts, each of which is rotatably connected to the furnace body and located inside the furnace body. The top rods are fixedly connected to the furnace body and pass through the furnace body.

[0011] This utility model discloses a continuous nitriding furnace. The furnace body provides support for the device, the inner cavity protects the material to be processed, and seals the interior of the furnace body. The support frame provides support and elasticity for the support springs. The protective plug seals the inner cavity, and the inner sealing strip seals the gap between the protective plug and the inner cavity. When filling material, the latch is opened, and the sealing cover and the inner cavity are removed from the furnace body via the pull rod. When removing the inner cavity, the support spring provides elasticity, pushing the protective plug against the interior of the inner cavity. The protective plug facilitates the sealing of the inner cavity, and the inner sealing strip seals the gap between the protective plug and the inner cavity. The sealing strip facilitates the sealing between the protective plug and the inner cavity, preventing gas leakage from the furnace. The sealing cover is then removed, the material to be processed is placed in the inner cavity, and the inner cavity is pushed into the furnace. The sealing assembly seals the furnace. During this pushing process, the push rod opens the protective plug and compresses the support spring, allowing gas from the furnace to enter the inner cavity and facilitating the processing of the material within. This solves the problem of gas leakage from the inner cavity during material placement and removal in horizontal high-pressure continuous vacuum nitriding furnaces, where an inner cavity protects the material and gas.

It is understood that the aforementioned solution can be used for sealing during material filling and unloading, and can also be used to increase the nitriding efficiency of the device.

[0021] In this specific embodiment, the inner cavity 102 is slidably connected to the furnace body 101 and located inside the furnace body 101; the support frame 103 is fixedly connected to the inner cavity 102 and located inside the inner cavity 102; the support spring 104 is fixedly connected to the support frame 103 and located outside the support frame 103; the protective plug 105 is fixedly connected to the support spring 104 and located between the support spring 104 and the inner cavity 102; and the inner sealing strip 106 is connected to the protective plug 105. 5. A fixed connection is established between the protective plug 105 and the inner cavity 102. The sealing assembly, the processing assembly, and the auxiliary assembly are respectively connected to the furnace body 101. The furnace body 101 provides support for the device.

When removing the inner cavity 102, the support spring 104 provides elastic force, pushing the protective plug 105 against the inside of the inner cavity 102. The protective plug 105 facilitates the sealing of the inner cavity 102, and the inner sealing strip 106 facilitates the sealing of the protective plug 105 and the inner cavity 102. The two parts are sealed to prevent gas leakage from the furnace body 101.

The protective plug 105 facilitates the cleaning of the inner cavity 102. The system is sealed, and the inner sealing strip 106 facilitates the sealing between the protective plug 105 and the inner cavity 102, preventing gas leakage from the furnace body 101. The sealing cover 107 is then removed, the material to be processed is placed in the inner cavity 102, and the inner cavity 102 is pushed into the furnace body 101. The sealing assembly seals the furnace body 101. During the pushing process, the push rod 115 pushes open the protective plug 105 and compresses the support spring 104, allowing gas from the furnace body 101 to enter the inner cavity 102, facilitating the processing of the material in the inner cavity 102.
