Description

Technical Field

[0001] This utility model relates to the technical field of scrap steel recycling and feeding devices, and in particular to intelligent scrap steel recycling and feeding devices. Background Technology

[0002] The existing patent publication number is (CN209940295U), which discloses an overhead crane device.

[0003] The existing patent publication number is (CN222729259U), which discloses an electromagnetic chuck for overhead cranes used for scrap steel.

[0004] In the existing technology, scrap steel is added by an overhead crane equipped with an electromagnetic chuck, enabling it to operate on multiple medium-frequency heating furnaces;

[0005] However, this method cannot efficiently monitor the weight of the added scrap steel online, and it is not very efficient.

[0006] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0007] Intelligent scrap steel recycling and feeding device

[0008] It includes several medium-frequency furnaces, which are arranged at intervals;

[0009] The ground track is installed inside the factory building;

[0010] A gantry frame, wherein a ground rail traveling part is provided at the lower end of the gantry frame, and the ground rail traveling part moves along the ground rail (the ground rail traveling part is consistent with the moving device for moving gantry frames in the prior art).

[0011] The hopper has an upward-opening cavity for loading scrap steel. The bottom of the hopper has a discharge port, and a limiting component and a driving component are provided at the discharge port. A support arm is provided on the gantry frame and connected to the hopper to support the hopper, so that the hopper is kept at a certain height under the action of the gantry frame. Then, when the ground rail travel part moves to the designated position, the discharge port of the hopper is aligned with the feed port of the medium frequency furnace.

[0012] Preferably, the gantry frame is also equipped with a rotatable screw and a stroke groove extending through one side. One end of the support arm is provided with a screw hole sleeve that cooperates with the screw to form a helical pair. The top of the gantry frame is provided with a reduction motor for driving the screw. After the screw is driven, the height of the support arm carrying the hopper is adjusted through the helical pair, which facilitates feeding of the medium frequency furnace at different heights.

[0013] Preferably, the bottom of the hopper is conical, and a tubular discharge device is fixed on the bottom wall. A spiral auger blade is rotated in the tubular discharge device. By driving the spiral auger blade, the scrap steel is discharged downward in an orderly manner. At the same time, when the spiral auger blade stops, it can provide a certain degree of obstruction and restriction (here, obstruction and restriction refers to the fact that, compared with the absence of spiral auger blade, the addition of spiral auger blade can reduce the free fall motion and speed of scrap steel).

[0014] Preferably, the hopper is provided with a drive unit on its side, which is equipped with a geared main motor and a matching electrical control system, and is connected to an external power source. It is coaxially connected to the main shaft of the auger blades through an extended shaft and drives the auger blades to rotate.

[0015] Preferably, an annular electromagnet actuator is fitted externally at the end of the discharge device, and an electromagnet control unit is also provided at the bottom of the hopper. The electromagnet control unit is connected to an external power source and controls whether the electromagnet actuator is magnetically activated. When the auger blades are rotating, the electromagnet actuator is turned off. When the auger blades stop, the electromagnet actuator is activated to magnetically attract and restrict the scrap steel within the discharge device, thereby stopping the discharge.

[0016] Preferably, an online weight control unit is also provided on the side of the hopper. One end of the support arm is inserted into the online weight control unit, which is equipped with a wireless electronic weighing scale. The two force-bearing ends of the wireless electronic weighing scale are respectively connected to two mounting bases. The support arm supports the wireless electronic weighing scale and, through the cooperation of the wireless electronic weighing scale and the mounting bases, supports the hopper. The weight of the hopper is monitored online to facilitate the calculation of the discharge mass.

[0017] The advantages and positive effects of this utility model are:

[0018] Compared to existing methods that use overhead cranes and electromagnets for material feeding, this device offers higher feeding efficiency and is safer.

[0019] The feeding height of this device is adjustable, which makes it more convenient to make adaptive adjustments for different models of medium frequency furnaces in the same factory (because the models are different, their external dimensions are different, and the height position of the feeding port is different).

[0020] The wireless electronic weighing system can monitor the weight reduction during the feeding process online, which can more accurately determine the weight of the scrap steel being fed compared to using a crane magnetic suction method. Attached Figure Description
