Description

A new type of high-efficiency pot furnace Technical Field

[0001] This invention relates to the technical field of pot furnaces. More specifically, this invention relates to a novel high-efficiency pot furnace. Background Technology

[0002] Chinese patent with publication number "CN114623687B" discloses an apparatus and method for removing slag from the molten pool during vacuum induction melting. This apparatus and method can remove slag, impurities and foreign matter floating on the surface of the molten pool during vacuum melting, thereby improving the purity of the molten pool and reducing quality defects in alloy ingots.

[0003] However, when replacing the triangular suction claw, the vacuum chamber needs to be opened, and the triangular suction claw needs to be replaced manually. During this process, the vacuum chamber needs to be frequently vented and evacuated, making the operation cumbersome and inefficient. At the same time, after the vacuum chamber is opened, some air will flow into the heating furnace, interfering with the vacuum heating operation.

In addition, during the replacement of the heat-conducting plate, the inner side of the outer shell 1 and the outer shell 2 can maintain a vacuum state, so even if the opening on the heating tank is opened, there will be no problem of air from the outside environment flowing into the heating tank and interfering with the heating operation.

[0019] 2. The hollow rod is tilted in the middle, so that the heat-conducting plate moves into the heating tank in an eccentric posture. Then, the hollow rod drives the heating tank to make a circular motion. Compared with the heat-conducting plate in a stationary state, the heat-conducting plate in a circular motion can adsorb scum over a wider range, which is conducive to improving the impurity removal efficiency and reducing the replacement frequency of the heat-conducting plate. At the same time, the protrusions increase the amount of scum adsorbed, which improves efficiency and further reduces the replacement frequency of the heat-conducting plate.

[0020] Third, pre-cooling the heat-conducting plate to be used by heat-conducting block two is beneficial to improving the efficiency of scum removal. The heat insulation cylinder and heat insulation box work together to intercept the heat in the heating tank and prevent the heat generated by the heating tank from being conducted to the heat-conducting plate to be used, so as to ensure the pre-cooling effect. At the same time, the impurities remaining on heat-conducting block two are removed by pipe seven and L-shaped through hole, so as to avoid interfering with the pre-cooling operation of the heat-conducting plate.

The hydraulic telescopic rod 2019 drives the pressure block 2020 to move obliquely downward, so that the pressure block 2020 presses the adjacent heat insulation cover 205 tightly, and then the hollow rod 9 is pulled away from the ring 3 207.

[0041] The drive assembly includes an electric slide rail 2021, an electric slider 2022, a connecting plate 2023, a hydraulic telescopic rod 2024, and a hydraulic telescopic rod 2025.

[0042] The rotating unit includes an electric slide rail 2026 and an electric slider 2027; the electric slide rail 2026 is connected to the outer casing 2; four electric sliders 2027 are slidably connected to the electric slide rail 2026, and the electric sliders 2027 are fixedly connected to the ring 204.

[0043] The working principle of the above embodiments is as follows:

[0044] First, the outer casing 2 is bolted to the machine frame in the factory. The first external suction pipe is manually connected to pipe 5, the second external suction pipe to pipe 202, and the third external suction pipe to heat insulation pipe 3011. The first coolant circulation system is connected to pipes 3013 and 4014. The external air supply pipe is connected to the round hole of the heat insulation cover 8. Then, the hydraulic telescopic rod 3 pushes the outer casing 2 and its parts to the left, causing the heating tank 7 to move to the left away from below the outer casing 2. The preset amount of material to be heated is then manually poured into the heating tank 7. The hydraulic telescopic rod 3 then moves the outer casing 2 and its parts back to their original position. The hydraulic telescopic rod 4025 moves the heat insulation cover 201 downwards, causing the heat insulation cover... Pipe 201 is inserted into the opening of heating tank 7, sealing the opening. Then, the first and second external suction pipes simultaneously begin evacuation, causing the air inside heating tank 7 to be discharged from pipe 202 into the second external suction pipe, drawing the inside of heating tank 7 to a near-vacuum state. Air inside outer shell 1 2 and outer shell 2 4 is discharged from pipe 1 5 into the first external suction pipe, drawing the inside of outer shell 1 2 and outer shell 2 4 to a near-vacuum state. Heating tank 7 then heats the material inside for a predetermined time, at which point scum forms on the surface of the molten material. Then, hydraulic telescopic rod 3 2024 drives heat insulation cover 1 8 downwards, and heat insulation cover 1 8 drives hollow rod 9 and its parts downwards, causing hollow rod 9 to insert into the inside of ring 3 207. Simultaneously, heat-conducting block 1... 2018 moves downwards, causing its slot 92 to fit onto the outside of the heat-conducting plate 2012. Simultaneously, heat insulation tube 3 2011 is inserted into the outside of heat insulation tube 1 208 and connected to it. At the same time, magnet 10 moves downwards to contact ring 3 207, and magnet 10 uses magnetic force to firmly attract ring 3 207. Then, the first coolant circulation system supplies coolant to pipe 3 2013. The coolant flows through pipe 3 2013 into the inside of the hollow rod 9, then flows downwards to heat-conducting block 1 2018, then upwards through square hole 91, and finally flows back to the first coolant circulation system from pipe 4 2014. During this process, the circulating coolant affects heat-conducting baffle 1 2015, heat-conducting baffle 2 2016, heat-conducting strip 2017, and heat-conducting... The heat on heat-conducting block 2018 is absorbed, and the heat on heat-conducting plate 206 is conducted to heat-conducting block 2018 through heat-conducting sheet 2012, and then absorbed into the circulating coolant, thereby cooling heat-conducting plate 206. Then, hydraulic telescopic rod 3 2024 drives heat insulation cover 8 and its parts upward, causing magnet 10 to drive ring 3 207 and its parts upward away from ring 2 204. Then, hydraulic telescopic rod 4 2025 drives heat insulation cover 201 upward away from heating tank 7. Then, electric slide rail 1 2021 and electric slider 1 2022 are activated. Electric slider 1 2022 drives connecting plate 2023 and its parts to the left, causing ring 3 207 and its parts to move above heating tank 7.Then, the hydraulic telescopic rod 2024 drives the heat insulation cover 8 and its parts downwards, causing the heat conduction plate 206 and its parts to move to the inside of the heating tank 7, with the heat conduction plate 206 close to the surface of the molten material. At this time, the heat insulation cover 8 is tightly closed at the opening of the heating tank 7. Then, the external gas supply pipe delivers inert gas into the heating tank 7 through the round hole on the heat insulation cover 8. The third external suction pipe draws gas from the heat insulation pipe 2011, causing the inert gas at the surface of the molten material to flow sequentially into the heat insulation pipe 209, the heat insulation pipe 2011, and the third external suction pipe. At this time, the inert gas generates suction on the scum, causing the scum to float. The slag moves along with the inert gas and is intercepted by the filter screen 2010, causing the slag to come into contact with the area around the port of the heat-conducting plate 206 corresponding to the heat insulation tube 209. Since the slag is at a high temperature and the heat-conducting plate 206 is at a low temperature, a large temperature difference is created, causing the slag to cool rapidly and adhere to the surface of the heat-conducting plate 206. Then, through the cooperation of the electric slide rail 2021, the electric slider 2022, and the hydraulic telescopic rod 2024, the ring 207 and its components are controlled to move away from the heating tank 7, and the ring 207 and its components are controlled to move back to their original position. (The third external...) The suction pipe stops suctioning. Then, the hydraulic telescopic rod 2019 drives the pressure block 2020 to move downwards at an angle, pressing the heat insulation cover 205 tightly. Then, the hydraulic telescopic rod 2024 drives the heat insulation cover 8 and its parts upwards, causing the hollow rod 9 to move the magnet 10 away from the ring 207. At the same time, the hollow rod 9 is pulled out of the ring 207, and the heat insulation tube 2011 is pulled away from the heat insulation tube 208. Simultaneously, the heat conducting block 2018 is pulled away from the heat conducting plate 2012. Then, the electric slide rail 2026 and the electric slider 2027 are activated. 7 drives the second ring 204 to rotate on the first ring 203. The second ring 204 drives the parts on it to rotate, causing the heat-conducting plate 206 with adsorbed scum to move away from below the hollow rod 9, and transporting the next clean heat-conducting plate 206 and its parts to below the hollow rod 9. Then, the above operation is repeated to perform the impurity removal operation again, realizing automatic replacement operation, which helps to improve efficiency. In addition, during the replacement process, the inner sides of the first outer shell 2 and the second outer shell 4 can maintain a vacuum state, so even if the opening on the heating tank 7 is opened, there will be no problem of air from the outside environment flowing into the heating tank 7 and interfering with the heating operation.

[0045] Based on the above working principle, we can see that the present invention has the following effects:

[0046] The system enables automatic replacement of the heat-conducting plate 206 used for adsorbing scum, eliminating the need for manual operation and greatly improving work efficiency. Furthermore, during the replacement of the heat-conducting plate 206, the inner sides of the outer shell 1 2 and outer shell 2 4 can maintain a vacuum state, so even if the opening on the heating tank 7 is opened, there will be no problem of air from the external environment flowing into the heating tank 7 and interfering with the heating operation.

[0047] Example 2

[0048] Based on Embodiment 1, as shown in Figures 1-9, it also includes a motor 2028; the motor 2028 is bolted to the heat insulation cover 8; the output shaft of the motor 2028 is connected to the hollow rod 9 through a gear set; the hollow rod 9 is rotatably connected to the heat insulation cover 8; the hollow rod 9 consists of two straight tubes and one inclined tube, and the two straight tubes are located at the two ends of the inclined tube respectively; the maximum horizontal distance between the two straight tubes of the hollow rod 9 is less than the inner diameter of the opening of the heating tank 7.

[0049] It also includes bumps 2029; several bumps 2029 are fixed on the heat-conducting plate 206.

[0050] The working principle of the above embodiments is as follows:

[0051] In Example 1, when transporting the heat-conducting plate 206 and the parts thereon to above the heating tank 7:

[0052] The hydraulic telescopic rod 32024 drives the heat insulation cover 8 and its components downwards, causing the heat conduction plate 206 and its components to move into the port of the heating tank 7. Then, the electric slide rail 1021 and the electric slider 1022 are activated. The electric slider 1022 drives the connecting plate 2023 and its components to move to the right. The hydraulic telescopic rod 32024 drives the heat insulation cover 8 to continue moving downwards, causing the hollow rod 9 to move diagonally downwards. The inclined tube portion of the hollow rod 9 moves to the inside of the heating tank 7 until the upper straight tube portion of the hollow rod 9 is aligned with the center of the heating tank 7. Then, the electric slider 1022 drives the connecting plate 2023, and the hydraulic... The telescopic rod 2024 drives the heat insulation cover 8 and its parts to continue moving downwards, causing the heat-conducting plate 206 to move above the surface of the molten material. The heat-conducting plate 206 is positioned eccentrically on the surface of the molten material. Then, the motor 2028 is started. The motor 2028 drives the hollow rod 9 to rotate back and forth through the gear set. The hollow rod 9 drives the heat-conducting plate 206 to perform circumferential motion, thereby enabling the heat-conducting plate 206 to adsorb impurities on the circumferential range of the molten material surface. Compared with the stationary heat-conducting plate 206, the circumferentially moving heat-conducting plate 206 can adsorb a wider range of scum, which is beneficial to improving the impurity removal efficiency and reducing the replacement frequency of the heat-conducting plate 206.

[0053] During the cooling process, the heat on the protrusion 2029 is conducted to the heat-conducting plate 206, and then dissipates along with the heat on the heat-conducting plate 206, thereby cooling and reducing the temperature of the protrusion 2029. During the air intake process of the heat insulation pipe 209, the gas carries the scum through the protrusion 2029, thereby causing some of the scum to cool and adhere to the protrusion 2029, which helps to increase the amount of scum adsorbed, improves efficiency, and further reduces the replacement frequency of the heat-conducting plate 206.

[0054] Based on the above working principle, we can see that the present invention has the following effects:

[0055] The hollow rod 9 is inclined in the middle, so that the heat-conducting plate 206 moves into the heating tank 7 in an eccentric posture. Then, the hollow rod 9 drives the heating tank 7 to perform a circular motion. Compared with the heat-conducting plate 206 in a stationary state, the heat-conducting plate 206 in a circular motion can adsorb scum over a wider range, which is conducive to improving the impurity removal efficiency and reducing the replacement frequency of the heat-conducting plate 206. At the same time, the protrusion 2029 increases the amount of scum adsorbed, improves efficiency, and further reduces the replacement frequency of the heat-conducting plate 206.

[0058] It also includes a cleaning component; the cleaning component is connected to the heat insulation box 2030; the cleaning component includes a hydraulic telescopic rod 2036, a baffle 2037 and a pipe 2038; two hydraulic telescopic rods 2036 are fixedly connected to the heat insulation box 2030; the telescopic ends of all hydraulic telescopic rods 2036 are fixedly connected to the baffle 2037; the pipe 2038 passes through the baffle 2037 and is slidably connected to the heat insulation box 2030, and the impurities remaining on the upper side of the heat-conducting block 2035 are removed through the pipe 2038; several L-shaped through holes 93 are opened on the ring 204, and the L-shaped through holes 93 are located above the outer side of the corresponding heat-conducting block 2035.

[0059] The working principle of the above embodiments is as follows:

[0060] During the heating operation of the heating tank 7 described in Example 1:

[0061] First, the second external coolant circulation system is manually connected to pipe five 2032 and pipe six 2034. The second external coolant circulation system delivers coolant to pipe five 2032. Under the interception of the baffle 2033, the coolant flows into the inner side of the first ring 203 through pipe five 2032, and then flows back to the second external coolant circulation system from pipe six 2034. The circulating coolant cools the second heat-conducting block 2035, and the heat-conducting plate 206 to be used is in close contact with the heat-conducting block 2035, thereby cooling the heat-conducting plate 206 to be used through the heat-conducting block 2035, achieving a pre-cooling effect, which is beneficial to improving efficiency. During this process, the heat insulation cylinder 6 and the heat insulation box 2030 work together to intercept the heat in the heating tank 7, preventing the heat generated by the heating tank 7 from being conducted to the heat-conducting plate 206 to be used, thus ensuring the pre-cooling effect. During the replacement process, the electric door 2031 is opened so that the hollow rod 9 can be inserted downward into the third ring 207.

[0062] First, the external vacuum hose is manually connected to pipe 7 2038. During regular maintenance, hydraulic telescopic rod 13 pushes the outer casing 12 and its parts to the left, then electric door 2031 opens, activating electric slide rail 2026 and electric slider 2027. Electric slider 2027 drives ring 204 and its parts to rotate intermittently, aligning the heat-conducting plate 206 and its parts with the opening of the insulation box 2030. Then, the heat-conducting plate 206 and its parts are manually removed from the insulation box 2030. Afterward, the heat-conducting plate 206 is cleaned. After removing the heat-conducting plate 206 and its parts, some impurities may remain on the heat-conducting block. On the second 2035, the heat transfer between the heat-conducting block 2035 and the new heat-conducting plate 206 is affected, thus interfering with the pre-cooling operation of the heat-conducting plate 206. Therefore, the hydraulic telescopic rod 2036 drives the baffle 2037 to move downward, so that the baffle 2037 covers the groove on the ring 204. The external suction pipe draws air into the pipe 7 2038, so that the air flows in from the upper end of the L-shaped through hole 93, and then flows into the groove from the lower end of the L-shaped through hole 93, and then flows into the external suction pipe through the pipe 7 2038, thereby removing the impurities remaining on the heat-conducting block 2035 and avoiding interference with the pre-cooling operation of the heat-conducting plate 206.

[0063] Based on the above working principle, we can see that the present invention has the following effects:

[0064] Pre-cooling the heat-conducting plate 206 to be used by the heat-conducting block 2035 helps improve the efficiency of scum removal. The heat insulation cylinder 6 and the heat insulation box 2030 work together to intercept the heat in the heating tank 7 and prevent the heat generated by the heating tank 7 from being conducted to the heat-conducting plate 206 to be used, so as to ensure the pre-cooling effect. At the same time, the impurities remaining on the heat-conducting block 2035 are removed by the pipe 7 2038 and the L-shaped through hole 93, so as to avoid interfering with the pre-cooling operation of the heat-conducting plate 206.

[0065] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
