Description

Technical Field

[0001] The utility model relates to the technical field of bell-type furnaces, and in particular to a high-temperature bell-type furnace for processing silicon steel. Background Art

[0002] High-temperature bell-type furnaces are commonly used in the heat treatment process of metal materials, such as the annealing of silicon steel. In the production of silicon steel, the role of a high-temperature bell-type furnace is to improve the magnetic properties of the material by controlling the heating environment. Usually, silicon steel sheets are placed in the furnace. After reaching the set high temperature value, the silicon steel sheets need to be kept in the furnace for a period of time to ensure that the material undergoes sufficient physical and chemical changes. The temperature in the furnace is then lowered to allow the silicon steel sheets to cool and complete the overall annealing treatment.

[0003] However, when using a high-temperature bell-type furnace for silicon steel processing and annealing, since all steps are carried out in the furnace, the heating, insulation and cooling work are carried out continuously. After the heating and insulation work, the temperature of the silicon steel will be too hot. When cooling in the furnace, the temperature is directly reduced. Since the cooling time is relatively short in mass production, if the cooling time of the cooling system is short or the flow rate of the cooling medium is insufficient, it may be difficult to take away the heat in the furnace in time, resulting in incomplete cooling. At the same time, the internal temperature cannot reach the set temperature quickly after setting. Therefore, after the silicon steel sheet is processed in the furnace, it is difficult for the silicon steel to be completely cooled. The temperature inside the silicon steel may still be too hot. Therefore, after the processed silicon steel comes out of the annealing furnace outlet, the silicon steel sheet will need to wait for a long time to cool down due to the overheated internal temperature. Utility Model Content

DETAILED DESCRIPTION

[0047] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] like Figures 1 to 6As shown, this embodiment proposes a high-temperature bell-type furnace for silicon steel processing, comprising a base 1, an outer cover 2 and a heating mechanism. The outer cover 2 is arranged on the top of the base 1, and the heating mechanism is arranged in the outer cover 2. It also includes a lifting mechanism, a furnace table 3, a rotating opening and closing mechanism, a water spraying mechanism, a transverse clamping mechanism and a drainage mechanism. The lifting mechanism is arranged at the bottom end of the base 1 for lifting and lowering the position of the silicon steel. The furnace table 3 is arranged on the top of the lifting mechanism for placing the silicon steel for processing. The rotating opening and closing mechanism is arranged on the top of the outer cover 2 for controlling the opening and closing of the outer cover 2. The water spraying mechanism is arranged on one side of the base 1 for spraying water to cool the processed silicon steel. The transverse clamping mechanism is arranged on the top of the water spraying mechanism for clamping the silicon steel raised by the lifting mechanism. The drainage mechanism is arranged on the outer wall of the outer cover 2 near the rotating opening and closing mechanism for discharging the sprayed water outward. The furnace table 3 is provided with a limiting ring 4 for the purpose of ensuring that the silicon steel sheet can remain stable during processing in the furnace and does not fall into the furnace.

[0049] In this embodiment, the lifting mechanism includes a hydraulic cylinder 101 and a lifting rod 102. The hydraulic cylinder 101 is installed at the bottom end of the base 1. The lifting rod 102 is fixedly connected to the output end of the hydraulic cylinder 101, and the top of the lifting rod 102 is fixedly connected to the furnace platform 3. A protective frame 6 is provided at the place where the output end of the hydraulic cylinder 101 and the lifting rod 102 are fixedly connected. This is mainly because the hydraulic cylinder 101 is installed at the bottom of the base 1, but the output end will extend into the interior of the outer cover 2, and the outer cover 2 serves as a seal for the furnace. Therefore, when the output end of the hydraulic cylinder 101 is placed inside the outer cover 2, the protective frame 6 is added to effectively avoid the adverse effects of the temperature of the high-temperature hood furnace on the hydraulic cylinder 101 when heating, insulating and cooling the silicon steel sheet.

[0050] In this embodiment, the rotating opening and closing mechanism includes a base 201, a rotating piece 203 and a top seat 205. The base 201 is fixedly connected to the top of the outer cover 2, and four fixed shafts 202 are fixedly connected to the base 201. Each fixed shaft 202 is rotatably connected to a rotating piece 203, and a rotating rod 204 is fixedly connected to the outer wall of one of the rotating pieces 203. The four rotating pieces 203 rotate in a linked manner, and the rotating piece 203 on the driving rod 204 will simultaneously drive the other three rotating pieces 203 to rotate synchronously. The top seat 205 is fixedly connected to the tops of the multiple rotating pieces 203, and a fixing hole 206 corresponding to the fixed shaft 202 is opened on the top seat 205. Each fixed shaft 202 passes through the rotating piece 20 3 extends from the fixing hole 206, and the fixed shaft 202 passes through the rotating piece 203. The end extending from the fixing hole 206 is parallel to the top of the top seat 205, mainly to better fix the positions of the base 201, the rotating piece 203 and the top seat 205, and ensure that the base 201 and the top seat 205 do not shift when the rotating piece 203 rotates. The four rotating pieces 203 are all set to the same arc shape, and the adjacent arc edges are in contact with each other. Therefore, by pushing the rotating rod 204, the rotating rod 204 will drive the rotating piece connected to the rotating rod 204 to rotate. At the same time, since the opening of the rotating piece 203 will push the other three rotating pieces 203 to open in the same trajectory, the four rotating pieces 203 will open and close synchronously.

[0051] In this embodiment, the water spraying mechanism includes a water tank 301, a water injection pipe 302, a connecting pipe 304 and an atomizing nozzle 305. The water tank 301 is detachably connected to one side of the base 1. The top of the water tank 301 is connected to the water injection pipe 302, and the other end of the water injection pipe 302 is connected to the input end of the water pump 303. The output end of the water pump 303 is connected to the connecting pipe 304. The connecting pipe 304 is connected to multiple atomizing nozzles 305. The atomizing nozzle 305 is used in the present invention. The atomizing nozzle 305 can disperse the liquid into tiny mist particles, which can better cover the target area, reduce the amount of liquid used, and improve the spraying efficiency.

[0052] In this embodiment, the transverse clamping mechanism includes a bracket 401, an electric cylinder 402, a push rod 403 and a clamping claw 404. The bracket 401 is fixedly installed on the top of the water tank 301 away from the end of the water injection pipe 302. The electric cylinder 402 is installed on the side wall of the bracket 401. The push rod 403 is fixedly connected to the output end of the electric cylinder 402. The clamping claw 404 is detachably connected to the other end of the push rod 403. The clamping claw 404 is a common automatic mechanical claw on the market and is only shown in the figure for reference.

[0053] In this embodiment, the drainage mechanism includes a water collecting sleeve 501 and a drainage pipe 502. The water collecting sleeve 501 is fixedly connected to the outer wall of the outer cover 2 close to the base 201. The drainage pipe 502 is connected to the bottom of the water collecting sleeve 501. The side where the water collecting sleeve 501 is connected to the outer cover 2 is set as an arcuate surface 5. The place where the water collecting sleeve 501 is connected to the drainage pipe 502 is set as an arcuate surface 5. The arcuate surface 5 is set to allow the water to spontaneously slide into the drainage pipe 502 through the arcuate surface 5 and be discharged outward through the drainage pipe 502 to prevent the water in the water collecting sleeve 501 from increasing and accumulating in the water collecting sleeve 501 and overflowing for cleaning.

[0054] In summary, the working principle of the high-temperature bell-type furnace for silicon steel processing is as follows: after using the high-temperature bell-type furnace to heat, keep warm and cool the silicon steel, first turn off the internal heater, and the worker rotates the rotating rod 204 to rotate the rotating piece 203 outward and open it. At the same time, the hydraulic cylinder 101 is started, and the lifting rod 102 is raised by the hydraulic cylinder 101. The furnace table 3 on the lifting rod 102 will slowly rise in the direction of opening the rotating piece 203. When the furnace table 3 is raised to the point where the silicon steel sheet on the furnace table 3 is completely exposed, the electric cylinder 402 is started, and the push rod 403 is pushed out, so that the clamping claw 404 on the push rod 403 clamps the silicon steel sheet on the furnace table 3. After the clamping claw 404 clamps the silicon steel sheet, the worker rotates the rotating rod 204 on the rotating piece 203. , so that the rotating piece 203 rotates inward to a closed state. At this time, the high-temperature bell-type furnace is in a closed state. At the same time, the water pump 303 is started, so that the water inside the water tank 301 is pressurized by the water pump 303 and flows to the water injection pipe 302, and then flows from the water injection pipe 302 to the connecting pipe 304, and the water is sprayed to the silicon steel sheet on the clamp 404 through the atomizing nozzle 305. Since the water sprayed by the atomizing nozzle 305 is relatively fine, but when the water spraying time is long, the water on the silicon steel sheet will slide onto the top seat 205 or into the water collecting sleeve 501. The water that slides into the water collecting sleeve 501 will flow to the discharge pipe and be discharged outward, completing the rapid cooling of the silicon steel sheet. According to the above process, the next group of silicon steel sheets will be cooled and shaped.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
