Description

Technical Field

[0001] This utility model relates to the field of smelting equipment technology, specifically to a smelting furnace for preparing nickel alloys that is easy to clean. Background Technology

[0002] The main function of a smelting furnace for preparing nickel alloys, designed for easy cleaning, is to melt and mix nickel and its alloying elements to produce nickel alloys with specific chemical compositions and physical properties. During the smelting process, the chemical composition of the alloy can be adjusted by adding different alloying elements to achieve the desired mechanical properties, corrosion resistance, heat resistance, and other characteristics. In the existing technology: Authorization Publication No. CN 114279217 Patent A discloses a vacuum melting furnace that is easy to clean. Two symmetrically distributed first side plates are fixed to one side of the top of the base plate, and two symmetrically distributed second side plates are fixed to the other side of the top of the base plate. A boiler is located between the two first side plates. A flipping mechanism is located on the outer side of the first side plates, and a cleaning mechanism is located between the tops of the two second side plates. While this equipment allows for cleaning by extending into the furnace chamber, the cleaning effect is limited and its versatility is relatively poor. Furthermore, the cleaning equipment may not be able to reach all corners and crevices of the furnace chamber during operation, resulting in incomplete cleaning and affecting the cleaning effect. Residual slag may affect the quality of the next melting process. Therefore, we propose a melting furnace for nickel alloy preparation that is easy to clean. Utility Model Content

The assembly / disassembly mechanism 6 also includes The upright 66, gear 67, and transmission plate 68 are rotatably connected to the right side of the bottom wall of cavity 5. Gear 67 is provided on the lower side of the outer arc surface of the upright 66, and transmission plate 68 is provided on the upper side of the outer arc surface of the upright 66.

Through the cooperation of mounting plate 61 and clamping plate 62, the furnace chamber 4 can be quickly disassembled. Then, according to the cleaning needs, different cleaning methods can be selected, such as water rinsing or chemical cleaning, which replaces the traditional method of cleaning by inserting cleaning equipment into the furnace chamber 4. This allows for a faster response to different situations and further improves the cleaning effect.

[0021] It also includes a control switch group 2, which is located at the front end of the housing 1. The input terminal of the control switch group 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0022] Wherein: A connecting plate 7 is slidably connected to the middle of the bottom wall of cavity 5. The front and rear sides of the connecting plate 7 are provided with evenly distributed teeth. The gear 67 is meshed with the longitudinally adjacent teeth respectively. A screw 8 is rotatably connected to the lower side inside the cavity 5. The screw 8 is threadedly connected to the threaded hole provided in the middle of the right end of the connecting plate 7. During the movement of the connecting plate 7, the connecting plate 7 will drive the gear 67 to rotate through the teeth. The gear 67 will drive the transmission plate 68 to rotate through the upright rod 66.

[0023] Among them: a motor 9 is installed on the lower right side of the housing 1. The left end of the output shaft of the motor 9 is fixedly connected to the right end of the screw 8. The input end of the motor 9 is electrically connected to the output end of the control switch group 2. The motor 9 starts to run by adjusting the control switch group 2. The output shaft of the motor 9 drives the screw 8 to rotate. During the rotation, the screw 8 will drive the connecting plate 7 to move to the left through the threaded connection.

[0024] The enclosure 1 has a mounting bracket 10 in the middle of its bottom wall. An electromagnetic coil 11 is wound around the outside of the mounting bracket 10. The furnace chamber 4 is located inside the electromagnetic coil 11. The input end of the electromagnetic coil 11 is electrically connected to the output end of the control switch group 2. The electromagnetic coil 11 is energized by the control switch group 2. When the alternating current passes through the electromagnetic coil 11, it generates a periodically changing magnetic field. The changing magnetic field generates an electromotive force in the conductor. In this case, the nickel alloy, as a conductor, generates an electromotive force inside. Since the nickel alloy is a conductive material, the generated electromotive force forms a closed current loop inside the nickel alloy. These currents are called eddy currents. Eddy currents are circulating currents generated inside the nickel alloy due to changes in the external magnetic field. When the eddy currents flow inside the nickel alloy, Joule heat (also known as resistance heat) is generated due to the resistance. This heat effect is the main heat source for induction heating. It heats the nickel alloy and eventually melts it, thereby realizing the smelting of the nickel alloy.

[0025] The working principle of the easy-to-clean nickel alloy preparation melting furnace provided by this utility model is as follows: During the use of the easy-to-clean nickel alloy preparation melting furnace, the nickel alloy to be melted is first poured into the furnace chamber 4. Then, through the control of the switch group 2, the electromagnetic coil 11 is energized. When the alternating current passes through the electromagnetic coil 11, it generates a periodically changing magnetic field. This changing magnetic field generates an electromotive force in the conductor. In this case, the nickel alloy, as a conductor, generates an electromotive force inside. Since the nickel alloy is a conductive material, the generated electromotive force forms a closed current loop inside the nickel alloy. These currents are called eddy currents. Eddy currents are circulating currents generated inside the nickel alloy due to changes in the external magnetic field. When the eddy currents flow inside the nickel alloy, Joule heating (also known as resistance heating) is generated due to the resistance. This heating effect is the main heat source for induction heating, which heats the nickel alloy and eventually melts it, thereby achieving the melting of the nickel alloy. After smelting, the smelted nickel alloy is poured out of the furnace chamber 4 by rotating the housing 1 using external equipment. At this time, there will be some impurities or slag inside the furnace chamber 4. Then, the motor 9 starts running by controlling the switch group 2. The output shaft of the motor 9 drives the screw 8 to rotate. During the rotation of the screw 8, the connecting plate 7 moves to the left through the threaded connection. During the movement of the connecting plate 7, the connecting plate 7 drives the gear 67 to rotate through the teeth. The gear 67 then drives the transmission plate 68 to rotate through the upright rod 66. At this time, the adjusting rod 65 slides inside the adjusting groove and rotates relative to the adjusting groove, so that the transmission plate 68 drives the upright plate 64 to move through the adjusting rod 65. The upright plate 64 then drives the clamping plate 62 to move through the mounting plate 61. At this time, the distance between the two clamping plates 62 gradually increases, and finally the clamping plate 62 separates from the outer surface of the furnace chamber 4, so that the furnace chamber 4 can be removed. Finally, the impurities or slag inside the furnace chamber 4 can be cleaned.

[0026] It is worth noting that the motor 9 disclosed in the above embodiments can be 5IK200A-AF, and the control switch group 2 is provided with a control button corresponding to the motor 9 for controlling its switch.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
