Description

Technical Field

[0001] The utility model relates to the technical field of metal processing and transfer, in particular to a graphite material metal liquid level controller. Background Art

[0002] In the field of metal material forming, metal smelting is an important link that requires refined production. In the process of molten metal transfer, it is crucial to control the liquid level of the molten metal in the container. If the liquid level is too low, the transfer cost will increase, and if the liquid level is too high, there will be a risk of transfer overflow.

[0003] In order to ensure the normal liquid level, the traditional method is to rely on visual inspection and experience control by operators, which may easily cause inaccurate transfer volume and increase the risk of overflow. Alternatively, ultrasonic instruments are used for control. However, ultrasonic instruments need to be installed in a room temperature environment and can only measure the liquid level of a single container. In the complex process of multiple containers in parallel, ultrasonic waves cannot make rapid adjustments based on container differences, and there are certain limitations in use.

[0008] As an improvement, a through hole is provided on the flow trough, and the central guide rod passes through the through hole and there is a certain friction force between the central guide rod and the through hole.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] Combined with Figure 1 and attached Figure 3 The graphite material metal liquid level controller comprises an aluminum liquid bag 1, above which is a flow channel 2, on which a liquid level gauge 3 is inserted, and the liquid level gauge 3 is composed of a float 5, a float handle 6 and a central guide rod 7.

[0024] Through the above structure, the liquid level gauge 3 composed of the float 5, the float handle 6 and the central guide rod 7 can directly control the liquid level of the aluminum liquid in the aluminum liquid ladle 1.

[0025] Combined with Figure 2 A through hole 4 is provided on the flow channel 2, the central guide rod 7 passes through the through hole 4 and there is a certain friction between the central guide rod 7 and the through hole 4, and high-temperature glue is applied between the float 5 and the float handle 6.

[0026] Through the above structure, the liquid level meter 3 can be directly inserted into the flow channel 2 or the water outlet of other furnaces by using the through hole 4, and high temperature glue is applied between the float 5 and the float handle 6 during assembly to continuously maintain the sealing performance.

[0027] Embodiment 2

[0028] Combined with Figure 3 The float 5 and the float handle 6 are fixed together by carbon fiber screws. The connection between the center guide rod 7 and the float handle 6 is a sliding connection. A wire 8 is provided in the center guide rod 7. A retaining ring 10 is provided at the bottom end of the center guide rod 7. An inner hole 11 for matching with the wire 8 is provided at the bottom end of the float 5. The inner hole 11 is connected to an external circuit. The bottom end of the wire 8 extends to the bottom of the retaining ring 10.

[0029] Through the above structure, the float 5 and the float handle 6 are connected and fixed together by carbon fiber screws, which are light in weight, high in strength and corrosion-resistant, and have high overall stability. When the liquid level rises and pushes the float 5 upward, the bottom end of the wire 8 in the center guide rod 7 and the circuit in the inner hole 11 are connected, forming a drain valve closing signal, thereby achieving the purpose of automatically closing the drain valve.

[0030] Combined with Figure 3 The outer surface of the conductor 8 is wrapped with mica insulating material 9, the central guide rod 7 is made of 310S material, the inner hole 11 is electrically connected to the external drain valve, and the float 5 is a stone mill hollow shell structure.

[0031] Through the above structure, the outer surface of the wire 8 is wrapped with mica insulating material 9, which can not only insulate heat, but also insulate the wire 8 from the central guide rod 7. The central guide rod 7 is made of 310S material, which has strong oxidation resistance and corrosion resistance. In addition, the inner hole 11 and the external liquid discharge valve are electrically connected, which is convenient for controlling the external liquid discharge valve.

[0032] When the utility model is implemented:

[0033] The liquid level meter 3 is directly fixed on the launder 2 by means of the through hole. During the production process, aluminum liquid continuously enters the aluminum ladle 1. As the aluminum liquid level continues to rise until it contacts the float 5, the float 5 and the float handle 6 are pushed upward.

[0034] As the float 5 rises, the inner hole 11 slowly moves upward. When the float 5 is pushed to the point where the wire 8 in the center guide rod 7 contacts the inner hole 11, the electric conduction is turned on to form a drain valve closing signal, thereby automatically closing the drain valve and stopping the liquid from entering, thereby achieving the purpose of accurately controlling the liquid level.

[0035] In addition, the overall float 5 is a stone mill hollow shell structure with outstanding high temperature resistance. The float 5 and the float handle 6 are connected and fixed together by carbon fiber screws, and high temperature glue is applied in the middle during assembly to continuously maintain the sealing. The center guide rod 7 is made of 310S material with strong oxidation resistance and corrosion resistance. The material of the overall liquid level meter 3 has stable chemical properties, good impermeability and corrosion resistance, and strong adaptability, thereby ensuring that the ideal liquid level can be maintained regardless of the container used.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
