[0002] The operating frequency of the medium frequency induction furnace is between 50 and 2000Hz. It is widely used for the smelting of non-ferrous metals and ferrous metals. Compared with other casting equipment, the medium frequency induction furnace has the advantages of high thermal efficiency, short smelting time, less alloy element burnout, a wide range of smelting materials, low environmental pollution, and the ability to accurately control the temperature and composition of the molten metal. When using the medium frequency furnace, the molten metal in the furnace needs to be dumped into an external container through a turning mechanism.

[0003] However, during the pouring process of the molten metal inside the furnace body, the staff needs to adjust the receiving position of the container according to the position of the material port. At this time, the staff is in close contact with the high-temperature molten metal, which is prone to splashing and causing safety hazards. Therefore, a safe material receiving device for a medium frequency smelting furnace is proposed. Utility Model Content

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in 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.

[0016] See also Figure 1-4The utility model provides a technical solution: a safe material receiving device for a medium frequency smelting furnace, comprising a bracket 1, a furnace body 2 and a material receiving hopper 3. A turning mechanism 4 is provided between the bracket 1 and the furnace body 2, a hook 5 is installed on the furnace body 2, and a support rod 6 which is built into the hook 5 is installed on the upper end of one side of the material receiving hopper 3. The furnace body 2 is tilted by the turning mechanism 4, so that the material receiving hopper 3 rotates under its own gravity to receive the material smelted in the furnace body 2. An adjusting component 7 for assisting the material receiving hopper 3 to be suspended or detached from the hook 5 is installed on the bracket 1.

[0017] The turning mechanism includes a rotating shaft installed on the furnace body, which is rotatably connected to the bracket through a bearing. A motor is installed on the bracket, a main gear is installed on the output end of the motor, and a slave gear is installed on the rotating shaft, and the main gear and the slave gear are meshed.

[0018] The hook-shaped portion 51 of the hook 5 matches the support rod 6, and the tip 52 of the hook 5 extends outward to limit the support rod 6, so as to prevent the hook 5 from rotating when the furnace body 2 is tilted, and the opening direction of the hook 51 of the hook 5 changes, causing the support rod 6 to detach. The end 53 of the hook 5 is connected to the inner end of the hook-shaped portion 51 at an inclined surface, which facilitates the support rod 6 to enter the hook-shaped portion 51.

[0019] When the hook 5 is in a vertical state at the furnace body 2, the hook-shaped part 51 thereof is extended toward the opening side of the furnace body 2 after the tip 52 thereof is extended. When the furnace body 2 is tilted, the furnace body 2 is deflected, and the opening of the hook-shaped part 51 changes with the deflection of the furnace body 2. When the smelted material in the furnace body 2 can pour outward along the inner wall of the furnace body 2, the extended end of the tip 52 is in a vertical state at this time, limiting the support rod 6 to prevent it from falling out.

[0020] A support block 8 is installed at the lower end of the receiving hopper 3 on the side corresponding to the support rod 6, and a pad 9 is detachably installed on the support block 8.

[0021] The adjustment assembly 7 includes a moving plate 71 . A moving mechanism 72 for driving the moving plate 71 to translate laterally is installed on the bracket 1 . A lifting mechanism 73 is installed on the upper end of the moving plate 71 . A supporting platform 74 is installed on the protruding end of the lifting mechanism 73 .

[0022] The moving mechanism includes a slide mounted on the bracket 1 , the moving plate 71 is slidably mounted on the slide, a driving motor is mounted on the bracket 1 , a lead screw is mounted on the output end of the driving motor, and the lead screw is screwed to the moving plate 71 .

[0023] The lifting mechanism is a lifting device in the prior art such as a hydraulic cylinder, a lifter, etc., which lifts and lowers the supporting platform 74 .

[0024] Working principle: The furnace body 2 is turned over by the turning mechanism 4 to dump the smelted material in the furnace body 2. When the furnace body 2 rotates, the receiving hopper 3 rotates in the hook 5 under the action of gravity, so that the opening of the receiving hopper 3 corresponds to the lower end of the dumping outlet of the furnace body 2, and then the smelted material is received. After the smelted material in the furnace body 2 is dumped out, the moving mechanism 72 is started to drive the support platform 74 to the lower end of the receiving hopper 3, and the lifting mechanism 73 is started so that the lifting mechanism 73 drives the support platform 74 to contact the lower end of the receiving hopper 3, and lifts the receiving hopper 3, so that the support rod 6 is separated from the hook 5, and the disassembly of the receiving hopper 3 is completed.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
