Description

TECHNICAL FIELD

[0001] The utility model relates to liquid level detection technical field, in particular to a high temperature liquid liquid level detection device. BACKGROUND

[0002] In the metal continuous casting and rolling process, the liquid level height of liquid metal needs to be detected in real time to control the flow of liquid metal at the outlet and ensure that the metal flow in and out of the casting and rolling area reaches a stable dynamic balance. Currently, the existing production process usually uses a traditional sensor direct measurement method to detect the liquid level height of liquid metal in the flow tank. Because the temperature around the flow tank is high, the detection distance of ordinary sensors is short, and the stability is poor when approaching the surface of high-temperature metal liquid, and the precision is low. The imported long-distance detection sensor is high in cost and has the problem of large installation space requirement. In order to solve the above problems, a liquid level detection device that can adapt to high-temperature environment and is low in cost needs to be designed. SUMMARY

[0003] Therefore, the utility model discloses a high temperature liquid liquid level detection device, which solves the problems of high cost, poor stability in high-temperature environment and low detection precision of the existing detection device.

[0004] A high temperature liquid liquid level detection device, comprising

[0005] A mounting plate;

[0006] A connecting rod assembly arranged on the mounting plate, wherein the connecting rod assembly comprises a connecting rod that can rotate in a vertical plane;

[0007] A float assembly arranged at one end of the connecting rod, wherein the float assembly comprises a float and a detection plate connected with the float;

[0008] A counterweight assembly arranged at the other end of the connecting rod;

[0009] A distance measuring assembly arranged above the detection plate, wherein the distance measuring assembly is used to test the distance between the distance measuring assembly and the detection plate.

[0010] The high-temperature liquid level detection device is placed in a containing high-temperature liquid container, the mounting plate can be fixed to the inner wall of the container or suspendedly fixed above the high-temperature liquid in the container, and the float is floated on the surface of the high-temperature liquid; when the high-temperature liquid level changes, the float moves with the change of the liquid level, thereby driving the detection plate connected with the float to produce displacement in height; the distance measuring assembly arranged above calculates the liquid level height and the liquid level change amount by measuring the distance between the detection plate and the distance measuring assembly; the counterweight assembly arranged at the other end of the connecting rod not only enables the float to float on the surface of the high-temperature liquid, but also plays a role in stabilizing the float, thereby avoiding the problem that the detection result is unstable due to the violent rolling of the float when the high-temperature liquid level changes. The device has a simple structure, can enable the distance measuring assembly to be in a safe position, avoid the influence of the temperature of the high-temperature liquid on the distance measuring assembly, improve the service life of the distance measuring assembly, and ensure the detection accuracy of the distance measuring assembly while the cost is relatively low.

[0011] Further, the connecting rod assembly further comprises a first connecting shaft fixed to the mounting plate, the connecting rod is connected to the mounting plate through the first connecting shaft, and the connecting rod can rotate around the first connecting shaft in the vertical plane.

[0012] Further, the connecting rod assembly further comprises a first connecting bearing sleeved on the outer surface of the first connecting shaft, and the connecting rod is sleeved on the outer surface of the first connecting bearing; the first connecting bearing is a ceramic bearing. The ceramic bearing has better high-temperature resistance and smaller friction resistance, and when the high-temperature liquid level changes, the float can more easily drive the connecting rod to rotate, so that the movement of the detection plate is more sensitive, and the measurement result of the distance measuring assembly is more accurate.

[0013] Further, the float assembly further comprises a float connecting rod, the detection plate is connected with the float through the float connecting rod; the float is fixedly connected to the bottom of the float connecting rod; the detection plate is fixedly connected to the top of the float connecting rod; and the float connecting rod is connected with one end of the connecting rod. The high-temperature liquid level detection device of the present scheme is provided with a float connecting rod connecting the detection plate and the float, which can keep the detection plate away from the high-temperature liquid surface and reduce the distance between the detection plate and the distance measuring assembly, thereby reducing the measurement error factor and facilitating the distance measuring assembly to be arranged at a position away from the high-temperature liquid surface to realize remote measurement.

[0014] Further, the float assembly is detachably connected with the connecting rod. Different float assemblies can be replaced to adapt to different detection environments, such as replacing the float assembly including the float connecting rod with different lengths to adapt the high-temperature liquid level detection device to high-temperature liquid containers with different sizes; replacing the float assembly including the float with different shapes and different melting points to adapt the high-temperature liquid level detection device to high-temperature liquids with different temperatures; and replacing the float assembly including the detection plate with different shapes and sizes to keep the detection plate always below the distance measuring assembly during movement with the high-temperature liquid level, thereby ensuring the normal measurement of the distance measuring assembly.

[0015] Further, the float connecting rod is connected with the connecting rod through a second connecting shaft, and the float connecting rod can rotate relative to the connecting rod in the vertical plane. When the high-temperature liquid level changes, the float pulls the float connecting rod to move and pull the connecting rod to rotate, and at the same time, the float connecting rod rotates relative to the connecting rod to keep the vertical state, thereby avoiding the inclination of the float connecting rod and the detection plate connected with the float connecting rod to cause errors in the measurement results of the distance measuring assembly, and further improving the detection accuracy.

[0016] Further, the connecting position of one end of the connecting rod on the float connecting rod is adjustable. The high-temperature liquid level detection device of the present application can adjust the size of the high-temperature liquid level detection device by adjusting the fixed position of the connecting rod on the float connecting rod, thereby adapting to high-temperature liquid containers with different sizes, and can also adjust the distance between the detection plate fixed with the float connecting rod and the distance measuring assembly, thereby reducing the error factors in measurement.

[0017] Further, the float is a rhombus-shaped float plate perpendicular to the float connecting rod. The rhombus-shaped float plate helps to divide the flowing metal liquid, thereby preventing the formation of flaky oxide scales on the liquid surface.

[0018] Further, the counterweight assembly includes a counterweight connecting rod and a counterweight block fixed at the bottom of the counterweight connecting rod.

[0019] Further, the distance measuring assembly includes a distance measuring sensor arranged above the detection plate, and the distance measuring sensor is arranged to face the detection plate; and the distance measuring sensor is used to measure the distance between the distance measuring sensor and the detection plate.
