Description

Technical Field

[0001] This utility model relates to the technical field of medium frequency furnaces, and in particular to a feeding device for a medium frequency electric furnace. Background Technology

[0002] An intermediate frequency electric furnace is a power supply device that converts 50Hz AC power into intermediate frequency (300Hz to 10000Hz). It consists of a frequency converter, furnace body, and furnace front control system. During operation, a feeding device is needed to transport the metal material to be processed into the furnace. Existing technology publication number CN208238530U discloses a feeding device for an intermediate frequency electric furnace. It includes a feeding hopper rotatably connected to the furnace and a hydraulic cylinder hinged to the furnace. The hydraulic cylinder is hinged to the feeding hopper, and a feeding rack is fixedly connected to the feeding hopper. While this improves feeding efficiency, before use, the worker needs to place the metal material to be processed in the feeding rack and then move the rack to the feeding hopper. The metal material in the rack is relatively heavy, making it inconvenient to handle. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a medium-frequency electric furnace feeding device that can prevent raw materials from splashing outside the furnace body, avoid injury to workers, and improve the safety performance of use.

[0004] This utility model discloses a medium-frequency electric furnace feeding device, comprising a base, a feeding component, a conveying component, and a discharging component. The feeding component is installed on the top left of the base, and the conveying component is installed on the top right of the base. The discharging component is installed on the conveying component. The material is added to the feeding component for preliminary processing, reducing the material volume and facilitating its addition to the medium-frequency furnace. The conveying component can move the discharging component to the feed inlet at the top of the medium-frequency furnace, and the material is added into the medium-frequency furnace through the discharging component. This prevents raw materials from splashing outside the furnace, avoiding injury to workers and ensuring the safe operation of the device.

[0005] Preferably, the feeding component includes two uprights, a feeding box, two rotating shafts, multiple sets of crushing blades, and a drive motor. The two uprights are fixedly installed at the front and rear ends of the top left side of the base. The feeding box is installed on the top of the uprights, and a discharge pipe is installed on the bottom right side of the feeding box. Two rotating shafts are rotatably installed inside the feeding box, and the two rotating shafts are connected by a drive gear. Multiple crushing blades are installed on the outer wall of the rotating shafts, with the left and right sides of the crushing blades alternately arranged. The input end of the rotating shaft is connected to the output end of the drive motor. When material is added to the feeding box, the drive motor is started to drive the rotating shafts to rotate, and the rotating shafts drive the crushing blades to rotate, crushing the raw material, reducing the material volume, and making it easier to add to the medium-frequency furnace.

[0006] Preferably, the conveying component includes two conveying beams, two reducers, two feeding motors, two feeding screws, and two moving blocks. The conveying beams are installed at the front and rear ends of the right side wall of the base, and conveying grooves are opened inside the conveying beams. The feeding screws are rotatably installed in the conveying grooves. The input end of the feeding screw is connected to the output end of the reducer, and the input end of the reducer is connected to the output end of the feeding motor. The two moving blocks are slidably installed in the conveying grooves, and the middle of the moving blocks is screwed onto the outer wall of the feeding screw. When the feeding motor is started, it drives the feeding screw to rotate through the reducer, thereby driving the moving blocks to move in the conveying groove, which can move the material to the feed inlet at the top of the medium frequency furnace for convenient use.

[0007] Preferably, the feeding component includes a feeding box, two electric telescopic rods, and a feeding plate. The front and rear side walls of the feeding box are fixedly connected to the moving block. The electric telescopic rods are fixedly installed at the front and rear bottom of the feeding box. The feeding plate is inserted into the bottom of the feeding box. The telescopic ends of the electric telescopic rods are connected to the front and rear ends of the right side wall of the feeding plate. After the moving block moves the feeding box to the inlet of the medium-frequency furnace, the electric telescopic rods are activated to push the feeding plate to the right, so that the outlet at the bottom of the feeding box opens, thereby adding the material into the medium-frequency furnace, preventing the raw material from splashing outside the furnace and avoiding injury to the workers.

[0008] Preferably, it also includes two support legs, two connecting rods, and two second connecting rods. The top ends of the two support legs are connected to the middle of the bottom end of the conveying beam. A connecting rod is installed between the side wall of the support leg and the bottom of the conveying beam. A second connecting rod is installed between the top of the conveying beam and the middle of the top of the base. The support legs support the bottom of the conveying beam, the connecting rods increase the connection strength between the support legs and the conveying beam to ensure the stability of the conveying beam during use, and the second connecting rods can increase the stability of the connection between the conveying beam and the base.

[0009] Preferably, it also includes a feeding hopper and a protective cover. The feeding hopper is installed at the feeding port on the top of the feeding box, and the protective cover is installed on the rear side wall of the feeding box. The feeding hopper can increase the feeding area during feeding, increasing the convenience of feeding, while the protective cover can protect the drive gear and improve safety.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the material is added to the feeding component to perform preliminary processing on the material, reduce the material volume, and facilitate its addition into the medium frequency furnace. The conveying component can drive the feeding assembly to move to the feeding port at the top of the medium frequency furnace. The material is added into the medium frequency furnace through the feeding assembly, which can prevent the raw material from splashing outside the furnace, avoid injury to the staff, and ensure the safe use of the device.
