Description

Technical Field

[0001] This utility model belongs to the field of metal liquid level measurement technology, and in particular relates to a measuring device for metal liquid level in a smelting furnace. Background Technology

[0002] In the zinc alloy casting process, there is a type of smelting furnace that is fixed in a platform and cannot be tilted. Casting can only be achieved by a robotic arm picking up and pouring material each time. After casting is completed, a certain amount of molten metal often remains at the bottom of the furnace. Due to the limitations of the furnace structure, it is difficult for operators to intuitively and accurately judge the height and weight of the remaining molten metal.

[0003] Currently, the common method is to estimate based on experience or use simple physical detection methods, such as inserting metal rods or thermocouples into the bottom of the furnace and then taking them out, and roughly judging the remaining amount by the height of the molten metal adhering to them. This estimation method has a large error. When switching between different grades of zinc alloys, the weight of the remaining bottom liquid is unclear, which will lead to inaccurate batching calculations, affect the subsequent control of alloy composition, and increase raw material waste and quality risks. Utility Model Content

[0004] The purpose of this invention is to address the current practice of using empirical estimation and simple physical detection methods, such as inserting metal rods, thermocouples, or other instruments into the furnace bottom and then removing them, to roughly determine the remaining amount based on the height of the molten metal adhering to the metal. This estimation method has large errors, affects subsequent alloy composition control, and increases raw material waste and quality risks. Therefore, this invention proposes a device for measuring the molten metal level in a smelting furnace.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a measuring device for the molten metal level in a smelting furnace, comprising:

[0006] The furnace body has a pouring gate on it;

[0007] The foldable support arm is connected to the support column via an mounting bracket. The support column is connected to the furnace body, and the foldable support arm is rotatably connected to the mounting bracket.

[0008] And a measuring rod, which is movably connected to a foldable support arm.

[0009] Furthermore, the aforementioned foldable support arm includes a first square steel, a second square steel, and a connecting sleeve. The second square steel is rotatably connected to the first square steel via a bearing, the first square steel is rotatably connected to the mounting component, and the connecting sleeve is connected to the second square steel.

[0010] Furthermore, the aforementioned mounting components include a mounting plate and a connecting block. The mounting plate is fixed to the support column by screws, and the connecting block is connected to the mounting plate.

[0011] Furthermore, the connecting block is provided with a connecting groove, and the first square steel is provided with a connecting shaft, which is rotatably connected in the connecting groove.

[0012] Furthermore, the aforementioned measuring rod is movably connected to the connecting sleeve, and the connecting sleeve is provided with a limit screw.

[0013] Furthermore, the aforementioned measuring rod is equipped with graduation lines.

[0014] This invention provides a device for measuring the molten metal level in a smelting furnace. It features a foldable support arm and a graduated measuring rod. The foldable support arm comprises a first square steel bar and a second square steel bar. One end of the first square steel bar is rotatably connected to a connecting block via a connecting shaft, while the other end has a pin for connecting to a bearing on the second square steel bar, allowing the two steel bars to fold. The measuring rod is then fitted with a connecting sleeve, allowing it to move vertically up and down within the sleeve. The upper edge of the connecting sleeve serves as the reading line for the scale. Initially, the device is folded up by default. After the robotic arm is cast, the worker unfolds the foldable support arm and manually inserts the measuring rod vertically into the furnace, keeping the bottom of the rod in contact with the liquid surface. Once the liquid level stabilizes, the corresponding scale value is read. This foldable design facilitates use in confined spaces, improving applicability. The device is low-cost, simple in structure, and highly stable, making it easy to store and operate on-site. The graduated rod directly reads the liquid level height, providing more accurate and repeatable measurements than previous methods, thus reducing raw material waste and improving composition control precision.

[0015] Therefore, this embodiment has the following advantages compared to the prior art:

[0016] A measuring device for molten metal level in a smelting furnace solves the problem of current methods that rely on empirical estimation and simple physical detection. These methods involve inserting metal rods, thermocouples, or other instruments into the furnace bottom and then removing them, roughly judging the remaining amount based on the height of the molten metal adhering to them.
