Description

Technical Field

[0001] The utility model relates to the technical field of liquid level observers, in particular to a quenching tank liquid level observation device. Background Art

[0002] The quenching tank is a container that holds the quenching cooling medium and provides sufficient cooling capacity for the workpiece quenching. During the production and processing process, if the liquid level in the quenching tank is too high, it is easy to overflow, which may lead to risks such as energy waste and environmental pollution; if the liquid level in the quenching tank is too low, the temperature of the product cannot drop quickly after quenching, which may easily cause the liquid in the quenching tank to burn and cause fire.

[0003] At the same time, the liquid level in the heat treatment quenching tank will change during the production process. Specifically, during the quenching process, some quenching liquid will be carried out by the quenched product, and some will automatically evaporate as the temperature continues to rise, which will cause the liquid level to drop. In the existing technology, the control of the quenching tank liquid level is usually done by on-site personnel directly observing the amount of quenching liquid in the quenching tank with the naked eye, and then adding it based on experience. This is very arbitrary when adding, and the specific amount to be added is not clear. If too much is added, the tank will overflow, and if too little is added, it will be added too frequently. As a result, this process has always relied on experienced technicians to specifically control it, adding too many uncontrollable factors. Therefore, it is necessary to design a liquid level observer to accurately observe the liquid level and control the amount of quenching liquid added. Utility Model Content

[0004] To this end, the utility model provides a quenching tank liquid level observation device to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] According to a first aspect of the present invention, a quench tank liquid level observation device includes a float, a guide rod, a guide column, and an indicator rod, wherein the guide rod, the guide column, and the indicator rod are all vertically arranged, the guide rod is slidably arranged in the guide column, and both ends of the guide rod extend outside the guide column;

[0007] The float is arranged at the bottom end of the guide rod;

[0008] The indicator rod is located outside the guide column, the top end of the indicator rod is connected to the top end of the guide rod, and the indicator rod and the guide rod form a U-shaped structure;

[0009] A liquid level indicating area is provided on the outer side wall of the guide column.

[0010] Furthermore, it also includes an indicator ring, which is horizontally arranged at the bottom end of the indicator rod and sleeved on the outside of the guide column.

[0011] Furthermore, the liquid level indicating area includes a red area and a green area, and the red area is located below the green area.

[0012] Furthermore, the red area and the green area are both annularly arranged on the outer side wall of the guide column.

[0013] Furthermore, the liquid level indicating area is provided with a liquid level scale line, and the liquid level scale line is arranged on the outer side wall of the guide column along the length direction of the guide column.

[0014] Furthermore, it also includes a fixing seat, which is arranged on the guide column.

[0015] Furthermore, the fixing seat is made of angle steel.

[0016] Furthermore, the guide column is cylindrical.

[0017] The utility model has the following advantages: the float ball floats on the top of the quenching liquid by buoyancy. During use, the float ball floats up and down as the quenching liquid level rises and falls. When the float ball floats up and down, it drives the guide rod to move up and down along the guide column. The guide rod drives the indicator rod to move up and down. By observing the position of the liquid level indicator area on the outer wall of the guide column at the bottom end of the indicator rod, the height of the quenching liquid can be accurately known. The entire device has a simple structure, is easy to manufacture and install, and has reliable performance. It can intuitively feedback the height of the quenching liquid level, so that on-site operators can more easily control the height of the quenching liquid level. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, a quenching tank liquid level observation device in an embodiment of the first aspect of the present invention includes a float 1, a guide rod 2, a guide column 3 and an indicator rod 8. The guide rod 2, the guide column 3 and the indicator rod 8 are all vertically arranged, the guide rod 2 is slidably arranged in the guide column 3, and the two ends of the guide rod 2 extend outside the guide column 3 respectively;

[0026] The float ball 1 is arranged at the bottom end of the guide rod 2;

[0027] The indicator rod 8 is located outside the guide column 3, and the top end of the indicator rod 8 is connected to the top end of the guide rod 2, so that the indicator rod 8 and the guide rod 2 form a U-shaped structure;

[0028] The guide column 3 is cylindrical, and a liquid level indicator area 5 is provided on the outer wall of the guide column 3. During use, the position of the bottom end of the indicator rod 8 in the liquid level indicator area 5 can be observed to know the level of the quenching liquid.

[0029] In this embodiment, it should be noted that the guide rod 2 is coaxial with the guide column 3 , and the guide rod 2 can slide up and down along the guide column 3 .

[0030] Furthermore, the operating principle of the entire device is as follows: the float 1 floats on the top of the quenching liquid by buoyancy. During use, the float 1 floats up and down with the rise and fall of the quenching liquid level. When the float 1 floats up and down, it drives the guide rod 2 to move up and down along the guide column 3. The guide rod 2 drives the indicator rod 8 to move up and down. By observing the position of the bottom end of the indicator rod 8 in the liquid level indicator area 5 on the outer wall of the guide column 3, the height of the quenching liquid can be accurately known.

[0031] The technical effects achieved by this embodiment are: the entire device has a simple structure, is easy to manufacture and install, has reliable performance, and can intuitively feedback the level of the quenching liquid, making it easier for on-site operators to control the level of the quenching liquid.

When the liquid level is higher than the green area 7, the liquid level is too high and is a wind control area, which is prone to overflow; the red area 6 is a warning area. When in the red area 6, quenching liquid can be selectively added. When it is below the red area 6, quenching liquid must be added.

[0041] Furthermore, the liquid level indicating area 5 is provided with a liquid level scale line, which is arranged on the outer side wall of the guide column 3 along the length direction of the guide column 3.
