DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0022] The present application relates to a mobile medium frequency furnace, such as Figure 1-5 As shown, the intermediate frequency furnace includes a frame 5 for serving as a basic support, and a furnace body assembly 3 for smelting operations is arranged at the center of the upper part of the frame 5. In order to facilitate the movement of the intermediate frequency furnace, casters 6 for convenient walking are arranged at the bottom of the frame 5, and a handrail 1 for the user to hold is added on one side of the frame 5, so that the user can push the handrail 1, and with the help of the rolling of the caster 6, the intermediate frequency furnace can be quickly and conveniently transported from one site to another, thereby improving the convenience of using the intermediate frequency furnace. A hot melt component 2 for heating operations is arranged inside the furnace body assembly 3, and in order to facilitate the pouring out of the melted molten liquid inside the furnace body assembly 3, a flip component 4 capable of driving the furnace body assembly 3 to rotate is also added on the upper part of the frame 5.

[0023] The furnace body assembly 3 includes a furnace shell 11, refractory bricks 12, an insulating layer 10, a fiberboard 8, a heater 9, and a furnace cover 7. The furnace shell 11 is placed on the outer surface of the furnace body assembly 3 and is connected to the frame 5 through a bearing seat. The inner bottom of the furnace shell 11 is provided with refractory bricks 12 for burn-through, the side wall of the furnace shell 11 is provided with an insulating layer 10 for insulation, the top of the insulating layer 10 is arranged with a fiberboard 8 for fixing, and the inner side of the insulating layer 10 is arranged with a heater 9 for preheating and insulation operations on the outside of the hot melt component 2, and a furnace cover 7 for sealing is also provided on the top of the furnace shell 11.

[0024] The hot melt assembly 2 includes a pot body 17, a cover plate 16, a coil 13, and a thermocouple 14. The pot body 17 is sleeved and arranged inside the heater 9. A detachably connected cover plate 16 is provided on the top of the pot body 17. A hot melt coil 13 connected to the cover plate 16 is provided inside the pot body 17. A thermocouple 14 for measuring the internal temperature of the furnace shell 11 is provided outside the pot body 17. In order to facilitate the addition of metal to be melted into the pot body 17, a feeding cover 15 connected by a snap is provided on the top of the cover plate 16, so that the user can remove the feeding cover 15 and then feed the metal to be melted into the furnace body. In order to facilitate the pouring out of the molten liquid in the pot body 17, an outwardly extending discharge port 18 is formed on one side of the pot body 17, so that the molten metal in the pot body 17 can be poured out through the discharge port 18.

[0025] The flip assembly 4 includes a bracket 21, a worm wheel 19, a worm 20, and a motor 22. The bracket 21 is arranged on one side of the frame 5. The top of the bracket 21 is provided with a worm wheel 19 connected to it through a bearing, and one end of the worm wheel 19 is connected to the furnace shell 11. A worm 20 connected to the bracket 21 is arranged below the worm wheel 19, and a meshing connection is adopted between the worm wheel 19 and the worm 20. In order to be able to drive the worm wheel 19 to rotate with the help of the worm 20, a motor 22 for driving the worm 20 to rotate is provided on one side of the worm 20. The worm 20 can be driven to rotate by the motor 22, so that the worm 20 can drive the worm wheel 19 to rotate synchronously, and the worm wheel 19 can drive the furnace body to perform an angle flipping operation, and the worm wheel 19 and the worm 20 structure can realize automatic locking operation when the worm 20 has no external force driving cylinder.

[0026] When in use, the medium frequency furnace is moved to a position where small batch production is required by means of casters 6. The applicant mainly uses it in the production of manhole covers. Manhole covers are mainly produced by casting. Therefore, the metal needs to be melted and poured into the mold for molding. The user opens the feeding cover 15 to put the metal to be melted into the pot body 17, and then fixes the feeding cover 15. Then the heater 9 and the coil 13 can be started. The power supply mode of the heater 9 and the coil 13 is external plug-in power supply, which is a common power supply mode, and the length of the wire can also be adjusted according to the user's needs. The actual design needs to be carried out, therefore, the power supply method and power supply distance will not be elaborated here. Then, the thermocouple 14 can be used to detect whether the temperature inside the furnace shell 11 for preheating and heat preservation is up to standard. Since the melting temperature inside the pot body 17 is relatively high, the thermocouple 14 is no longer used for temperature measurement. After the metal inside the pot body 17 is completely melted, the motor 22 can be used to drive the worm 20 and the worm wheel 19 to rotate, thereby driving the furnace body assembly 3 to flip, pour out the molten liquid inside the pot body 17, and then pour it into the mold for manhole cover production, thereby completing the preliminary casting operation of the manhole cover.

In addition, under the guidance of the present application, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present application. Therefore, the present application is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are within the scope protected by the present application.
