Description

Technical Field

[0001] This utility model relates to the field of feeding system technology, specifically a feeding system for a medium-frequency furnace. Background Technology

[0002] In the aluminum electrolysis production process, the connection between the anode guide rod and the anode carbon block is assembled using pig iron as the medium. The core equipment for smelting pig iron in the anode assembly process is the medium-frequency furnace, and the equipment for transporting pig iron is the feeding trolley. The feeding trolley needs to travel back and forth between the pig iron storage area and the medium-frequency furnace. There are operators in both the pig iron storage area and the medium-frequency furnace area. During the movement of the medium-frequency furnace, it is easy to bump into the operators, causing personal injury. Utility Model Content

[0003] The main purpose of this utility model is to provide a medium-frequency furnace feeding system to solve the problem in the prior art where medium-frequency furnaces are prone to hitting operators during movement, causing personal injury.

[0004] To achieve the above objectives, this utility model provides a medium-frequency furnace feeding system, including a medium-frequency furnace, a feeding trolley, and a track for the feeding trolley to travel on. The feeding trolley includes a base frame, with wheels at the bottom and a counterweight, a tiltable hopper, a hydraulic cylinder capable of tilting the hopper, and an oil supply system for supplying oil to the hydraulic cylinder at the top. Radar detection alarms are fixedly installed at the front and rear ends of the base frame.

[0005] Furthermore, the front end of the hopper is hinged to the base frame, and both ends of the hydraulic cylinder are hinged to the base frame and the hopper, respectively.

[0006] Furthermore, it also includes an overhead crane for feeding materials onto the feeding trolley. The overhead crane is equipped with a hoist, and the hoist is equipped with a lifting rope. The lifting rope is connected to a hook, and the hook is attached to an electromagnetic chuck.

[0007] Furthermore, the radar detection alarm is electrically connected to the power switch of the feeding trolley.

[0008] This utility model, by setting up a radar detection alarm, can sense whether there are any operators nearby during the movement. Once an operator is detected, an alarm will be issued immediately to prevent the feeding trolley from hitting the operator and causing personal injury.

[0009] This invention, by incorporating an overhead crane and an electromagnetic chuck, enables convenient and quick loading of pig iron material from the pig iron storage area onto a feeding trolley; and by featuring a tiltable hopper, it facilitates unloading. Attached Figure Description

[0013] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 As shown, according to an embodiment of the present invention, a medium-frequency furnace feeding system is provided, including a medium-frequency furnace 1, a feeding trolley 2, and a track 3 for the feeding trolley 2 to travel on. The feeding trolley 2 includes a base frame 201, with wheels 202 at the bottom of the base frame 201, a counterweight 203 at the top, a tiltable hopper 204, a hydraulic cylinder 205 capable of tilting the hopper 204, and an oil supply system 206 for supplying oil to the hydraulic cylinder 205. The oil supply system 206 includes an oil tank, an oil pipe for connecting the oil tank and the hydraulic cylinder 205, and an oil pump installed on the oil pipe. Radar detection alarms 4 are fixedly installed at the front and rear ends of the base frame 201.

[0015] By setting up a radar detection alarm 4, it can sense whether there are any operators nearby during the movement. Once an operator is detected, an alarm will be issued immediately to prevent the feeding trolley 2 from hitting the operator and causing personal injury.

[0016] The front end of the hopper 204 is hinged to the base frame 201, and the two ends of the hydraulic cylinder 205 are hinged to the base frame 201 and the hopper 204 respectively.

[0017] It also includes a crane 5 for feeding materials onto the feeding trolley 2. The crane 5 is equipped with a hoist 501, a lifting rope 502 is provided on the hoist 501, the lifting rope 502 is connected to a hook 503, and the hook 503 is attached to an electromagnetic chuck 6.
