[0001] The utility model relates to a simple device for measuring a liquid boundary line in an opaque container. Background Art

[0002] Pharmaceutical and chemical plants often use opaque containers to hold and / or settle specific liquids. After standing and / or settling, the contents separate into two parts: the upper layer, a relatively clear, lower-density supernatant, and the lower layer, a relatively denser precipitate. In practice, the supernatant is typically used, while the precipitate is discarded.

[0003] Since the container is opaque, operators cannot determine the liquid dividing line between the supernatant and the precipitate, which makes it difficult to control the production process.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0034] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.

[0035] like Figure 1 — Figure 8 As shown, a simple device for measuring the boundary line of liquids in an opaque container comprises a bracket 1, a pay-off device 2, and a float 3. A bracket fixing portion 12 is provided on the lower side of the bracket 1 for detachable connection to the upper edge of the container 4. A cantilever 15 is provided on the upper side of the bracket 1, and a wire guide wheel 16 is provided at the end of the cantilever 15 away from the pay-off device 2. The pay-off device 2 comprises a pay-off wheel 21 mounted on the bracket 1 and a measuring wire 22. One end of the measuring wire 22 is connected to and wound around the pay-off wheel 21, while the other end extends along the pay-off direction of the cantilever 15, passes around the wire guide wheel 16, and is connected to the float 3 at its end, which is suitable for measuring the boundary line between two immiscible liquids. The bracket 1 is fixed to the upper edge of the opaque container 4 via the bracket fixing portion 12, with the cantilever 15 facing the inner cavity of the container 4. During testing, the measuring line 22 is slowly released through the payout device 2, causing the float 3 to drive the measuring line 22 slowly downward from the upper liquid 5 (supernatant) to stop at the boundary between the upper liquid 5 (supernatant) and the lower liquid 6 (precipitate). The release of the measuring line 22 is then stopped. The measuring line 22 is then tightened, and the length of the measuring line 22 immersed in the liquid is recorded, which represents the depth of the liquid in the upper part of the container 4. This allows the precise location of the liquid boundary to be determined. This technical measure has the advantages of simple structure and easy operation.

[0036] like Figure 1 — Figure 4As shown, the bracket 1 includes a support plate 11, a bracket fixing portion 12, a pay-off wheel mounting portion 14, and a cantilever 15. The bracket fixing portion 12 includes an inner positioning plate 121 and an outer positioning plate 122 spaced apart below the support plate 11. The gap between the inner positioning plate 121 and the outer positioning plate 122 is greater than the width of the upper edge of the container 4. The outer positioning plate 122 is provided with a threaded positioning hole, in which a positioning bolt 13 is installed. When installing the bracket 1, align the bracket fixing portion 12 of the bracket 1 with the upper edge of the container 4, and make the inner positioning plate 121 abut against the inner side of the upper edge of the container 4, and then rotate the positioning bolt 13 on the outer positioning plate 122 so that the end of the positioning bolt 13 abuts against the outer side of the upper edge of the container 4. The installation of the bracket 1 is completed. In actual use, the bracket fixing portion 12 of the bracket 1 can adopt a clamping structure such as a clip.

[0037] like Figure 1 — Figure 4 As shown, the support plate 11 is provided with a pay-off reel mounting portion 14, which includes a first vertical plate 141 and a second vertical plate 142 spaced apart. The pay-off reel 21 is disposed between the first vertical plate 141 and the second vertical plate 142, and a rotating handle mounting hole is provided corresponding to the central through-hole of the pay-off reel 21. The rotating handle 211 includes a handle section and a connecting section. The connecting section of the rotating handle 211 passes through the rotating handle mounting hole and is fixedly connected to the central through-hole of the pay-off reel 21. The connecting section of the rotating handle 211 is clearance-fitted with the mounting hole of the rotating handle 211.

[0038] like Figure 1 — Figure 4 As shown, the end of the cantilever 15 away from the pay-off device 2 is provided with a wire guide wheel 16. Specifically, the cantilever 15 includes a first cantilever 151 and a second cantilever 152 spaced apart, and the first cantilever 151 and the second cantilever 152 are respectively provided corresponding to the first vertical plate 141 and the second vertical plate 142. The ends of the first cantilever 151 and the second cantilever 152 close to the pay-off device 2 are fixedly connected to the first vertical plate 141 and the second vertical plate 142 respectively; the ends of the first cantilever 151 and the second cantilever 152 away from the pay-off device 2 are connected to the wire guide wheel 16 via a pin 17.

[0039] like Figure 1 — Figure 4As shown, the pay-off device 2 includes a pay-off reel 21 and a measuring line 22 mounted on the bracket 1. One end of the measuring line 22 is connected to and wound around the pay-off reel 21, while the other end extends along the pay-off direction of the cantilever 15 and passes vertically downward around the line guide wheel 16. A float 3 suitable for the interface between two immiscible liquid levels is connected to the end of the measuring line 22. Specifically, the pay-off reel 21 of the pay-off device 2 is rotatably connected between the first vertical plate 141 and the second vertical plate 142 of the pay-off reel mounting portion 14 by rotating the handle 211. One end of the measuring line 22 is connected to and wound around the pay-off reel 21, while the other end extends along the pay-off direction of the cantilever 15 and passes vertically downward around the line guide wheel 16. A float 3 suitable for the interface between two immiscible liquid levels is connected to the end of the measuring line 22. In actual use, the bracket 1 has the technical advantages of simple structure, low manufacturing cost, and easy installation.

[0040] The float 3 is detachably connected to the measuring line 22. In actual use, different floats 3 may be required for different densities of the upper liquid 5 (supernatant) and lower liquid 6 (precipitate). This detachable connection between the float 3 and the measuring line 22 allows for a wider range of applications. The float 3 and measuring line 22 can be connected using threads, hooks, or other methods. This technical solution offers the advantages of easy replacement and a wider range of applications.

[0041] Specifically, the float 3 comprises an upper annular cylindrical portion 31 and a lower counterweight portion 32. The cavity formed within the annular cylindrical portion 31 serves as the upper liquid chamber, and the volumetric specific gravity of the counterweight portion 32 is set to be the same as the density of the lower liquid 6. A threaded post 34 is located at the center of the upper end of the counterweight portion 32, and a connecting portion 221 is located at the lower end of the measuring line 22. The connecting portion 221 has internal threads that mate with the threaded post 34. In actual use, the threaded post 34 at the center of the upper end of the counterweight portion 32 can be used as a hanging ring, while the connecting portion 221 of the measuring line 22 can be used as a hook. The annular cylindrical portion 31 is made of a thin, lightweight, rigid material, such as thin rigid plastic or thin aluminum alloy. The threaded post 34 is also made of a lightweight, rigid material. The counterweight portion 32, located at the lower portion of the float 3, has its volumetric specific gravity set to be the same as the density of the lower liquid 6. During operation, the liquid chamber of the annular cylindrical portion 31 is filled with the upper layer of liquid 5, ensuring that no lower layer of liquid 6 or solid impurities are mixed in. When the float 3 is submerged in the liquid, it will spontaneously sink to the liquid boundary. When the float 3 reaches the liquid boundary, the upper end surface of the counterweight 32 is aligned with the boundary between the upper and lower layers of liquid 5, 6.

[0042] like Figure 8 As shown, in actual use, the counterweight portion 32 of the float 3 can have a variety of shapes. Specifically, the float 3 includes an upper annular cylindrical portion 31 and a lower counterweight portion 32. The counterweight portion 32 is cylindrical with an outer diameter identical to that of the annular cylindrical portion 31. This structure offers the advantages of simplicity and ease of manufacturing.

[0043] In actual use, the counterweight portion 32 may also be in a conical shape. Figure 1 、 Figure 5 — Figure 7 As shown, the counterweight portion 32 of the float 3 is conical, with a larger top and smaller bottom. The outer diameter of the upper end of the counterweight portion 32 is the same as that of the annular cylindrical portion 31. Compared to a cylindrical counterweight portion 32, the conical counterweight portion 32 allows the float 3 to be immersed more easily and gradually in the test liquid, until it is completely submerged while the measuring string is suspended. This technical measure can significantly improve work efficiency.

[0044] In actual use, the counterweight portion 32 is generally a solid structure. However, in actual use, there is a problem of needing to fine-tune the weight of the counterweight portion 32. The weight of the counterweight portion 32 can be fine-tuned by providing the counterweight hole 322 and the counterweight.

[0045] like Figure 5 — Figure 7 As shown, specifically, the counterweight part 32 includes a counterweight part body and a cover body 33; a circular groove 321 for installing the cover body 33 is provided at the upper end of the counterweight part body; the counterweight part body and the cover body 33 are detachably connected; a plurality of counterweight holes 322 for counterweighting are evenly distributed on the circumference of the upper side of the counterweight part 32 body, and counterweight weights of the same weight (not shown in the figure) are respectively provided in the counterweight holes 322; the counterweight weights and the counterweight holes 322 have the same shape, and the gap between the two is matched; a threaded column 34 is fixedly connected to the center of the cover body 33; the threaded column 34 is threadedly connected to the cylindrical connecting part 221.

[0046] The material of the counterweight is generally the same as or similar to the material of the counterweight portion 32. When configuring the counterweight, the counterweight is arranged symmetrically, with at least two counterweights being provided in the two opposite counterweight holes 322.

[0047] The above is a detailed introduction to the technical solutions provided by the embodiments of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
