Description

Technical Field

[0001] The utility model belongs to the technical field of high-temperature sintering furnaces, and particularly relates to a cooling device for a high-temperature sintering furnace. Background Technique

[0002] A high-temperature sintering furnace is an industrial device used for sintering materials at high temperatures, and is widely used in fields such as powder metallurgy, ceramic industry, and metal material processing. It can provide a high-temperature environment, promote the migration of atoms inside the material, and realize the transformation from powder to dense body. The design requirements of a high-temperature sintering furnace are to be able to withstand high temperatures, have good heat insulation performance, and be able to precisely control the heating rate and temperature distribution to ensure the quality and efficiency of the sintering process. The working principle of a high-temperature sintering furnace is usually based on resistance heating, induction heating or other heat sources to transfer heat to the materials inside the furnace. The furnace body structure design should ensure that the heat is concentrated in the working area, and at the same time, reduce heat loss through effective heat insulation materials. The control system of the high-temperature sintering furnace is responsible for monitoring and adjusting the heating process to ensure the uniformity and stability of the temperature. After the sintering process of the high-temperature sintering furnace is completed, it needs to be cooled to protect the equipment and ensure the material properties. The cooling methods include natural cooling, forced air cooling, water cooling system or rapid cooling device.

[0003] At present, when using water cooling to cool a high-temperature sintering furnace, due to the excessively high furnace temperature of the high-temperature sintering furnace, water will be evaporated under the action of the temperature of the high-temperature sintering furnace to form water vapor, and the formed water vapor is generally directly discharged into the external environment. However, because the water vapor has a high temperature, it will cause harm to equipment or personnel. Based on this, a cooling device for a high-temperature sintering furnace is proposed.

[0020] Embodiment

[0021] As Figures 1-4As shown in the figure, a cooling device for a high-temperature sintering furnace includes an outer furnace body 1, a furnace cover 2 and an inner furnace body 3. The furnace cover 2 is rotatably connected to the outer furnace body 1. A pressure relief valve is installed on the outer furnace body 1 to prevent deformation and damage of the outer furnace body 1 caused by excessive internal pressure during sintering and cooling. The inner furnace body 3 is fixedly connected inside the outer furnace body 1. Two legs 4 are fixedly connected to the bottom of the outer furnace body 1. A circulating water cooling mechanism is installed at the bottom of the outer furnace body 1. The drainage end of the circulating water cooling mechanism is located between the outer furnace body 1 and the inner furnace body 3. A transmission component is installed on the circulating water cooling mechanism. An air conveying mechanism is installed on the outer furnace body 1. Driven by the transmission component, the air conveying mechanism extracts the water vapor generated during cooling between the outer furnace body 1 and the inner furnace body 3. The exhaust end of the air conveying mechanism is located inside the circulating water cooling mechanism. The circulating water cooling mechanism includes a water tank 501 arranged at the bottom of the outer furnace body 1. A water pump 502 is fixedly connected to one side of the water tank 501. The output end of the water pump 502 is fixedly connected to a water delivery pipe 503. A spray head 504 is fixedly connected to the water delivery pipe 503. The spray head 504 penetrates through the side wall of the outer furnace body 1 and extends into the interior of the outer furnace body 1. The spray head 504 is located at the top of the inner furnace body 3. The input end of the water pump 502 is communicated with the water tank 501. A water guide groove 506 is opened at the bottom of the outer furnace body 1. A connecting sleeve 505 is fixedly connected to the bottom of the outer furnace body 1. The connecting sleeve 505 is communicated with the water guide groove 506. When adding water, water can be added into the water tank 501 through the water guide groove 506. The connecting sleeve 505 is fixedly connected to the top of the water tank 501. The water tank 501 is fixedly connected between the two legs 4.

[0022] During use, when cooling the inner furnace body 3, start the water pump 502 so that the water pump 502 extracts the water flow inside the water tank 501 into the water delivery pipe 503, and then sprays it on the outer surface of the inner furnace body 3 through the spray head 504 to cool the inner furnace body 3. Part of the cooled water will evaporate into water vapor under the high temperature of the inner furnace body 3, and the other part of the water will flow back into the water tank 501 through the connecting sleeve 505 under the action of the water guide groove 506. This process is repeated until the temperature of the inner furnace body 3 reaches room temperature, achieving effective cooling of the inner furnace body 3, saving resources, and preventing water flow in the operating environment of the sintering furnace, which affects the cleanliness of the operating environment.

[0023] As Figures 2-5As shown in the figure, the transmission assembly includes a rotating chamber 601 fixedly connected to the water delivery pipe 503. A rotating shaft 602 is rotatably connected to the rotating chamber 601. A blade 603 is fixedly connected to the part of the rotating shaft 602 located inside the rotating chamber 601. A first bevel gear 604 is fixedly connected to the side wall of the rotating shaft 602. The air delivery mechanism includes an air extraction pipe 701 fixedly connected to the outer furnace body 1. The air extraction pipe 701 penetrates through the water tank 501 and extends into the interior of the water tank 501. A plurality of air injection holes 702 are formed in the part of the air extraction pipe 701 located inside the water tank 501. One-way valves are installed in the plurality of air injection holes 702, so that the water vapor inside the air extraction pipe 701 can only be discharged into the water tank 501. A fixing frame 703 is fixedly connected inside the air extraction pipe 701. A rotating rod 704 is rotatably connected to the fixing frame 703. A fan blade 705 is fixedly connected to the rotating rod 704. A second bevel gear 706 is fixedly connected to the top of the rotating rod 704. The second bevel gear 706 meshes with the first bevel gear 604. The rotating shaft 602 penetrates through the air extraction pipe 701 and is rotatably connected to the air extraction pipe 701.

[0024] During use, during the process of water-cooling the inner furnace body 3, since there is water flow inside the water delivery pipe 503, the water flow will impact the blade 603 when flowing, causing the blade 603 to rotate, and then driving the rotating shaft 602 to rotate. The rotation of the rotating shaft 602 will drive the rotating rod 704 to rotate through the first bevel gear 604 and the second bevel gear 706, and then cause the fan blade 705 to rotate, generating an air extraction effect in the air extraction pipe 701, sucking the water vapor evaporated under the high temperature of the inner furnace body 3 into the air extraction pipe 701, and re-discharging it into the water tank 501 through the air injection holes 702;

[0025] This prevents the water vapor from being directly discharged into the external environment, causing harm to the equipment and personnel. At the same time, it can cool the water vapor, making the water vapor cool down and turn back into water, saving water resources. In addition, this air delivery method does not require the assistance of a blower, saving energy and reducing costs.

[0026] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
