[0031] Embodiment:

[0032] The following will further elaborate on the present utility model in conjunction with the attached Figures 1-4 drawings.

[0033] Please refer to Figures 1-4 , the present utility model provides a technical solution: a non-oxidizing rapid cooling and cryogenic heat treatment device, including a cooling chamber 1, a plurality of mounting holes 2 are opened on both sides of the cooling chamber 1, the mounting holes 2 on both sides of the cooling chamber 1 correspond to each other one by one, and a roller 3 is rotatably connected in the mounting hole 2;

[0034] Four mounting grooves 17 are opened on both sides of the cooling chamber 1, a water cooling device 18 is arranged in each of the four mounting grooves 17, and the four water cooling devices 18 are all located above the roller 3;

[0036] Specifically, a support rod 9 is fixedly connected to one side of each of the plurality of pipe supports 7, the other ends of the plurality of support rods 9 are fixedly connected to a rotating plate 10, a plurality of blocking rods 11 are fixedly connected to the other side of the plurality of rotating plates 10, a sliding frame 12 is fixedly connected to the bottom of the inner wall of the cooling chamber 1, a sliding plate 13 is slidably connected in the sliding frame 12, a rack 14 is fixedly connected to the top of the sliding plate 13, the rack 14 meshes with the blocking rods 11 on one side of each of the plurality of rotating plates 10 respectively, an electric push rod 15 is fixedly connected to one side of the inner wall of the cooling chamber 1, and a push plate 16 is fixedly connected to the output end of the electric push rod 15, and the other side of the push plate 16 is fixedly connected to one side of the sliding plate 13.

[0037] By adopting the above technical solution, through the rotating plate 10, the sliding frame 12, the rack 14 and the electric push rod 15, etc., when the spray pipe 8 sprays nitrogen, the spray pipe 8 is driven to rotate reciprocally through the pipe support 7, so that nitrogen can be evenly sprayed on the material, making the cooling of the material more uniform.

[0038] Specifically, the water cooling device 18 includes a first fixing plate 181 and a second fixing plate 183. The first fixing plate 181 and the second fixing plate 183 are respectively connected to the installation grooves 17 on both sides of the cooling chamber 1. A plurality of water cooling circulation pipes 182 are connected to both the first fixing plate 181 and the second fixing plate 183. The plurality of water cooling circulation pipes 182 are all connected through an interconnecting pipe 184. Interfaces 185 are provided at both the inlet and outlet of the water cooling circulation pipe 182, and on-off valves 186 are provided at positions of the water cooling circulation pipe 182 close to the inlet and outlet.

[0039] By adopting the above technical solution, the first fixing plate 181 and the second fixing plate 183 are pressed against the silicone sealing gasket and installed in the installation groove 17 to prevent external air from entering the cooling chamber 1, so as to convey cooling water for cooling operation. The conveying pipeline of the cooling water is connected through the interface 185 and adjusted through the on-off valve 186. According to the usage requirements, the cooling water conveyed by the water cooling circulation pipe 182 can be replaced with liquid nitrogen to perform cryogenic heat treatment on the material.

[0040] Specifically, electromagnetic valves 5 are provided on a plurality of nitrogen pipelines 4. The plurality of electromagnetic valves 5 are all located on one side of the cooling chamber 1. A plurality of exhaust branch pipes 19 are provided at the top of the cooling chamber 1. The plurality of exhaust branch pipes 19 are all communicated with the cooling chamber 1. A same exhaust main pipe 20 is connected to the plurality of exhaust branch pipes 19. The plurality of exhaust branch pipes 19 are all communicated with the exhaust main pipe 20. An electric valve 21 is provided on the exhaust main pipe 20.

[0041] By adopting the above technical solution, through the electromagnetic valve 5, it is convenient to adjust the flow rate of the nitrogen gas conveyed in the nitrogen pipeline 4. Through the exhaust branch pipes 19, the exhaust main pipe 20 and the electric valve 21, the waste furnace gas in the cooling chamber 1 is discharged.

[0042] The working principle of the present utility model is as follows: When in use, the staff installs the cooling chamber 1 at the rear of the heat treatment furnace hearth. During heat treatment, the cooling chamber 1 is in a sealed state and is not communicated with the heat treatment furnace. After the material heat treatment is completed, the position where the heat treatment furnace is connected to the cooling chamber 1 is opened. There is a rotating roller in the heat treatment furnace. Through the cooperation of the rotating roller and the supporting roller 3, the material is placed on the supporting roller 3 in the cooling chamber 1, and then the cooling chamber 1 is sealed. Through the operation of the electric valve 21 on the exhaust main pipe 20, the waste furnace gas in the cooling chamber 1 is discharged through a plurality of exhaust branch pipes 19, enters the exhaust main pipe 20, and is then discharged from the other end of the exhaust main pipe 20.

[0043] By connecting a cooling water delivery pipe to the interface 185 at the inlet of the water-cooling circulation pipe 182, cooling water is put into the water-cooling circulation pipe 182, discharged at the outlet of the water-cooling circulation pipe 182 after being transported, so as to carry out the heat in the cooling chamber 1, and through the on-off valve 186, it is convenient to control the flow rate of the cooling water. The water-cooling circulation pipes 182 are connected through the interconnection pipes 184, so that the cooling water flows evenly through each water-cooling circulation pipe 182, and the cooling effect is better. The interconnection pipe 184 is a flexible pipe. When one water-cooling circulation pipe 182 is damaged on the water-cooling device 18, the staff can change the connection position of the interconnection pipe 184, so as to repair and replace the damaged water-cooling circulation pipe 182 without affecting the work.

[0044] By connecting a nitrogen delivery pipe to one end of the nitrogen pipeline 4, nitrogen is put into the nitrogen pipeline 4, enters the air injection pipe 8 through the rotary joint 6, and is ejected from the other end of the air injection pipe 8 to cool the material on the idler 3, and the cooling effect is better. Compared with the traditional cooling only by water cooling, the cooling chamber 1 of this device is in a closed state, effectively avoiding the oxidation of the material during cooling. When the air injection pipe 8 ejects nitrogen for cooling, an external power supply is used to supply power to the electric push rod 15. By the elongation of the electric push rod 15, the sliding plate 13 is driven by the push plate 16 to slide to one side of the sliding frame 12 in the sliding frame 12. The rack 14 on the sliding plate 13 meshes to drive the stop rod 11 to rotate, thereby driving the rotating plate 10 to rotate. The rotating plate 10 drives the pipe support 7 to rotate counterclockwise, so as to adjust the jet angle of the air injection pipe 8.

[0045] After the air injection pipe 8 rotates counterclockwise to a certain angle, the sliding plate 13 contacts one side of the sliding frame 12 and cannot move any further. At this time, the electric push rod 15 shortens, driving the sliding plate 13 to slide reversely in the sliding frame 12. The rack 14 meshes to drive the rotating plate 10 to rotate reversely, thereby driving the air injection pipe 8 to rotate clockwise to adjust the angle, and stops when the sliding plate 13 contacts the other side of the sliding frame 12. When cooling the material by jetting gas, the nitrogen is sprayed more evenly and the cooling effect is better. By repeating this process, the cooling efficiency is improved. Through the electric valve 21 installed at the nitrogen pipeline air inlet position, the flow rate of the nitrogen entering is adjusted according to different usage requirements.

[0046] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
