Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level measurement equipment, and in particular relates to a liquid level measuring device for a lower layer of a mixed liquid. Background Art

[0002] Measuring the level of two immiscible liquids with distinct densities in a mixture held in a closed container or opaque tank presents challenges. In actual production, processes where the level of the lower layer cannot be accurately measured at any time typically rely on simply analyzing the liquid discharged from a fixed-height drain port to determine the lower layer's level. This inaccurate and time-sensitive measurement method can lead to long-term deviations in process indicators, ultimately impacting control of smaller indicators and product quality. Using specialized measuring instruments to measure the level of the lower layer in a mixture incurs significant costs and incurs ongoing maintenance obligations. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems and provide a device for measuring the level of the lower layer of liquid in a mixed liquid.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A device for measuring the liquid level of the lower layer of a mixed liquid comprises a base, a track rod, a float, a lower limit plate, an upper limit plate, a pointer bracket and a pointer, wherein the track rod is vertically arranged in the middle of the top surface of the base, the float is movably sleeved on the track rod, the lower limit plate is fixed on the track rod above the float, the upper limit plate is fixed on the upper end of the track rod, the pointer is a circular ring structure, movably sleeved on the track rod between the lower limit plate and the upper limit plate, and scale lines are provided on the track rod between the lower limit plate and the upper limit plate, and the pointer is connected to the float through the pointer bracket.

[0006] Furthermore, the density of the float satisfies ρ 上 <ρ 浮 <ρ 下 ;

[0007] where ρ 上 is the density of the upper liquid, ρ 浮 is the density of the float, ρ 下 is the density of the lower liquid.

[0008] Furthermore, the density of the base is greater than the density of the underlying liquid.

[0009] Furthermore, the length of the track rod between the lower limit plate and the base, the length of the track rod between the lower limit plate and the upper limit plate, and the height of the pointer bracket are the same.

[0010] Furthermore, the scale line at the lower limit plate is a zero scale line.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model determines the liquid level of the lower layer by density. Compared with the original measurement method of determining the liquid level of the lower layer after discharging the liquid through multiple drainage ports at fixed heights, the device is more scientific, the measurement value is more accurate, and more timely;

[0013] 2. The utility model has a simple structure, is easy to operate, easy to carry, highly flexible and has strong applicability.

[0014] 3. The utility model has no loss in operation and can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3As shown, a device for measuring the liquid level of the lower layer of a mixed liquid includes a base 4, a track rod 5, a float 6, a lower limit plate 7, an upper limit plate 8, a pointer bracket 9 and a pointer 10. The track rod 5 is vertically arranged in the middle of the top surface of the base 4. The density of the base 4 is greater than the density of the lower layer liquid 2. The float 6 is movably mounted on the track rod 5. The lower limit plate 7 is fixed on the track rod 5 above the float 6. The upper limit plate 8 is fixed on the upper end of the track rod 5. The density of the float 6 is greater than the density of the upper layer liquid 3 and less than the density of the lower layer liquid 2. The pointer 10 is a circular ring structure and is movably mounted on the track rod 5 between the lower limit plate 7 and the upper limit plate 8. A scale line 11 is provided on the track rod 5 between the lower limit plate 7 and the upper limit plate 8, and the lower limit plate 7 is the zero scale line. The pointer 10 is connected to the float 6 through the pointer bracket 9; the length of the track rod 5 between the lower limit plate 7 and the base 4, the length of the track rod 5 between the lower limit plate 7 and the upper limit plate 8, and the height of the pointer bracket 9 are the same. When the float 6 drops to the base 4, the pointer 10 drops to the position of the lower limit plate 7. When the float 6 rises to the position of the lower limit plate 7, the pointer 10 rises to the position of the upper limit plate 8.

[0021] The utility model comprises a series of devices with different base diameters, different track rod lengths and different float densities, and is suitable for measuring the liquid levels of different liquid containers 1 and liquids with different densities.

[0022] The working process of this utility model:

[0023] During the production process, after the mixed liquids of different densities and mutual incompatibility in the liquid container 1 are left to stand for a certain period of time, the liquid with lower density floats up to form the upper layer of liquid 3, while the liquid with higher density sinks to form the lower layer of liquid 2;

[0024] The device of the present invention is placed in a liquid container 1, and the base 4 is sunk to the bottom of the liquid container 1. Since the density of the float 6 is greater than the density of the upper liquid 3 and less than the density of the lower liquid 2, the float 6 floats up along the track rod 5 to the interface between the lower liquid 2 and the upper liquid 3. At the same time, the pointer 10 moves to the corresponding position along with the float 6 via the pointer bracket 9. At this time, the operator looks straight at the pointer 10. The scale line 11 pointed by the pointer 10 is the height of the lower liquid 2. The height of the upper liquid 3 is equal to the total height of the liquid minus the height of the lower liquid 2.

[0025] When measuring other liquids, the utility model only needs to be taken out from the liquid container 1 and then placed in a new container.
