Abstract
Description
Technical Field
[0001] This utility model relates to the field of medium-frequency steel shell furnace feeding technology, and in particular to a medium-frequency steel shell furnace feeding device. Background Technology
[0002] The core function of a medium-frequency steel shell furnace is metal melting. It utilizes the principle of electromagnetic induction to generate an alternating magnetic field within the furnace, inducing currents (eddy currents) within the metal charge. This converts electrical energy into heat energy, achieving rapid heating and melting of the metal. This equipment can efficiently melt various metals such as iron, steel, copper, and aluminum.
[0003] Existing medium-frequency steel shell furnaces typically have their feed inlets located at the top, requiring manual lifting of materials to be fed into the furnace from the top. Since medium-frequency steel shell furnaces are used for smelting metals, which are generally quite heavy, manual feeding is extremely laborious. Therefore, there is an urgent need to develop a feeding device for medium-frequency steel shell furnaces that facilitates material lifting, allows for the addition of heavier materials, and saves manpower, thus overcoming the shortcomings of current applications and meeting current needs. Utility Model Content
[0004] The purpose of this invention is to provide a feeding device for a medium-frequency steel shell furnace to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A medium-frequency steel shell furnace feeding device includes a frame, a lifting mechanism, a lifting plate, a telescopic material guiding mechanism, and an angle adjustment mechanism. The frame is fixed to the ground on one side of the medium-frequency steel shell furnace. The lifting mechanism is installed inside the frame and is used to drive the lifting plate to move up and down. The telescopic material guiding mechanism is rotatably connected to the lifting plate. The angle adjustment mechanism is installed on the lifting plate and is used to drive the telescopic material guiding mechanism to rotate. The telescopic material guiding mechanism includes: an inner shell, a support shaft, an outer shell, an electric telescopic rod, and sliding plates. The support shaft is fixed to the outer side of the inner shell and is rotatably connected to the lifting plate. The outer shell is slidably installed on the outer side of the inner shell. The electric telescopic rod is fixed to the bottom of the inner shell, and the telescopic end of the electric telescopic rod is fixed to the outer shell. Sliding plates are fixed on both sides of the outer shell and inserted into the outer wall of the inner shell. The sliding plates are in sliding contact with the outer wall of the inner shell.
[0006] Preferably, the outer wall of the inner housing is provided with a limiting groove for the movement of the sliding piece.
[0007] Preferably, the lifting mechanism includes: a first motor, a lead screw, a threaded sleeve, a slider, and a linear slide rail. The first motor is fixed on the frame, the lead screw is rotatably connected inside the frame, the output shaft of the first motor is fixed to the lead screw via a coupling, a threaded sleeve is installed on the lead screw, the threaded sleeve is fixed to the lifting plate, sliders are fixed on both sides of the lifting plate, each slider is slidably installed on a linear slide rail, and the linear slide rail is fixed inside the frame.
[0008] Preferably, the angle adjustment mechanism includes a second motor, a first gear, and a second gear. The second motor is fixed to the lifting plate, the first gear is fixed on the output shaft of the second motor, a second gear meshing with the first gear is provided on one side of the first gear, and the second gear is fixed on the support shaft.
[0009] Preferably, the transmission ratio of the first gear and the second gear is 1:1.
[0010] Preferably, a PLC controller is mounted on the side of the frame, and the first motor, the electric telescopic rod, and the second motor are all electrically connected to the PLC controller.
[0011] The beneficial effects of this utility model are as follows: When feeding material into this medium-frequency steel shell furnace, the telescopic material guide mechanism is first placed at its lowest position and retracted to its shortest length, ensuring it is horizontal. Then, a person places the material into the inner shell. Next, a first motor drives a lead screw to rotate, which in turn moves a threaded sleeve upwards. This movement, in turn, moves a lifting plate upwards, extending the telescopic material guide mechanism above the furnace. An electric telescopic rod then pushes the outer shell forward, increasing the length of the telescopic material guide mechanism. A second motor then drives a first gear and a second gear to rotate, which in turn rotates a support shaft. This rotation causes the inner and outer shells to tilt towards the furnace. Finally, the material inside the inner shell slides down into the furnace under gravity. In summary, this utility model facilitates material lifting, makes it easier to add heavier materials to the furnace, and saves manpower. Attached Figure Description

The telescopic end of the electric telescopic rod 404 is fixed to the outer shell 403. Sliding pieces 405 inserted into the outer wall of the inner shell 401 are fixed on both sides of the outer shell 403. The sliding pieces 405 slide in contact with the outer wall of the inner shell 401. The outer wall of the inner shell 401 is provided with a limiting groove 4011 for the movement of the sliding pieces 405. In use, the outer shell 403 is moved back and forth by the electric telescopic rod 404, thereby adjusting the overall length of the telescopic material guiding mechanism 4.
[0023] The lifting mechanism 2 includes: a first motor 201, a lead screw 202, a threaded sleeve 203, a slider 204, and a linear slide rail 205. The first motor 201 is fixed on the frame 1. The lead screw 202 is rotatably connected inside the frame 1. The output shaft of the first motor 201 is fixed to the lead screw 202 via a coupling. The threaded sleeve 203 is installed on the lead screw 202 and is fixed to the lifting plate 3. Slider 204s are fixed on both sides of the lifting plate 3. Each slider 204 is slidably mounted on a linear slide rail 205. The linear slide rail 205 is fixed inside the frame 1. In use, the first motor 201 drives the lead screw 202 to rotate, which in turn drives the threaded sleeve 203 to move up and down, and the threaded sleeve 203 in turn drives the lifting plate 3 to move up and down.
[0024] The angle adjustment mechanism 5 includes a second motor 501, a first gear 502, and a second gear 503. The second motor 501 is fixed on the lifting plate 3.

Then, material is placed into the inner shell 401. The first motor 201 drives the lead screw 202 to rotate, which in turn moves the threaded sleeve 203 upwards. The threaded sleeve 203 then moves the lifting plate 3 upwards, which in turn extends the telescopic material guide mechanism 4 into the medium-frequency steel shell furnace. Above, the outer shell 403 is pushed forward by the electric telescopic rod 404 to increase the length of the telescopic material guiding mechanism 4. Then, the second motor 501 drives the first gear 502 and the second gear 503 to rotate. The second gear 503 drives the support shaft 402 to rotate. The support shaft 402 drives the inner shell 401 and the outer shell 403 to rotate, so that the inner shell 401 and the outer shell 403 tilt towards the medium-frequency steel shell furnace. Finally, the material in the inner shell 401 slides down into the medium-frequency steel shell furnace under the action of gravity.
