Description

Technical Field

[0001] The utility model relates to a liquid separation indicating device, belonging to the technical field of liquid separation. Background Art

[0002] Liquid separation is a technique used to separate two or more immiscible liquids from a mixture. Typically, separation is accomplished by using density differences, with the higher density liquid being called the upper layer and the lower density liquid being called the lower layer.

[0003] Currently, there are two types of liquid separation indicators used in conventional liquid separation operations. One type is simply a transparent pipe design. In actual operation, when the colors of the upper and lower layers are very similar, it is difficult to visually determine the stratification interface, and misjudgment often leads to remixing of the separated liquids. The other type uses the principle of a communicating vessel, with additional holes opened in the storage and separation equipment or delivery pipeline, and then judged by an external indicator. However, such a setting will inevitably affect the pressure resistance of the container itself, shortening its service life. It also takes up a lot of space, and during daily operations, the probability of accidental collision and damage is high. Therefore, it is of practical significance to develop a liquid separation indicator device. Utility Model Content

[0005] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: A liquid dispensing indicating device comprises: an observation portion, which is a hollow tubular structure, an indicating tube is arranged inside the observation portion, the indicating tube is perpendicular to the horizontal plane and an indicating mark that can move up and down is arranged inside the indicating tube, and stoppers are arranged on the upper and lower ends of the indicating tube; a connecting assembly comprises a first flange arranged at one end of the observation portion and a second flange arranged at the other end of the observation portion, the first flange and the second flange are connected and fixed to the observation portion by a fastening device.

[0006] Furthermore, no less than three indicator tubes are provided inside the observation portion, and the indicator tubes are parallel to each other and form a group of three.

[0007] Furthermore, three groups of indicator tubes are provided on the inside of the observation portion, namely the first group, the second group and the third group. The internal indicator of the first group is the first indicator, the internal indicator of the second group is the second indicator, and the internal indicator of the third group is the third indicator. The first indicator, the second indicator and the third indicator have the same volume but different density.

[0008] Furthermore, the indicator tubes are attached to the inner wall of the observation portion, and adjacent indicator tubes are in contact with each other.

[0009] Furthermore, the side wall of the observation portion has a preset thickness, and the indicator tube is formed by an opening in the side wall of the observation portion.

[0010] Furthermore, the first indicator, the second indicator and the third indicator have different colors.

[0011] Furthermore, the indicator mark is spherical, and the outer diameter of the indicator mark is 0.5-0.7 times the inner diameter of the indicator tube.

[0012] Furthermore, the relationship among the height of the indicator tube, the height of the observation portion and the inner diameter of the observation portion satisfies the following: height of the indicator tube: height of the observation portion: inner diameter of the observation portion = 1:1:(0.65-0.8).

[0013] Furthermore, the inner wall of the indicator tube is symmetrically provided with V-shaped grooves.

[0014] Furthermore, a sealing ring is provided at the contact point between the first flange and the observation part, and at the contact point between the second flange and the observation part.

[0024] The following is a detailed description of the specific embodiments of the present invention. The present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "disposed" should be understood in a broad sense. For example, they may refer to fixed connection or disposition, detachable connection or disposition, or integral connection or disposition. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] like Figure 1-Figure 3 As shown, the utility model provides a liquid dispensing indicating device, comprising: an observation portion 1, the observation portion 1 being a hollow tubular structure, an indicating tube 2 being arranged on the inside of the observation portion 1, the indicating tube 2 being perpendicular to the horizontal plane and having an indicating mark 3 which can be moved up and down arranged inside thereof, and a stopper 4 being arranged on the upper and lower ends of the indicating tube 2; a connecting assembly comprising a first flange 5 arranged at one end of the observation portion 1 and a second flange 6 arranged at the other end of the observation portion 1, the first flange 5 and the second flange 6 being connected and fixed to the observation portion 1 by a fastening device.

[0029] It should be noted that, in the embodiment of the present invention, the observation portion 1 is made of a transparent material, and the stopper 4 is a mesh grille detachably connected to the openings at both ends of the indicator tube 2, and its main function is to prevent the indicator mark 3 from detaching from the indicator tube 2. It can also be a mesh, a perforated plate, etc. The stopper 4 can meet the requirements of liquid circulation and indicator mark 3 blocking. It should be noted that, in order to facilitate the distinction between the indicator tube 2 and the indicator mark 3, the stopper 4 is attached. Figure 2 In the figure, the stopper 4 is only shown on one of the indicator tubes 2. During actual operation, the upper and lower ports of each indicator tube 2 are provided with a stopper 4; the first flange 5 and the second flange 6 are detachably connected to the two ends of the observation part 1. During operation, the liquid flows through the first flange 5, the observation part 1, and the second flange 6 in sequence; in the embodiment of the present invention, the fastening device is a screw 7 and nut 8 structure inserted between the first flange 5 and the second flange 6. The fastening device can not only fix the position of the observation part 1 to prevent loosening, but also strengthen the seal to prevent leakage. The fastening device can also be a snap-fit ​​structure.

[0030] Through the above settings, firstly, the liquid separation interface can be quickly determined by visual inspection during the liquid separation process, which effectively solves the problem that it is difficult to find the stratification interface when the colors of the upper and lower liquid layers are close. It is easy to use and improves the efficiency of liquid separation and extraction. The current component situation in the kettle can be judged in time by the position of the indicator 3, which provides the operator with more information and increases the basis for judgment of the liquid separation results. Secondly, through the above settings, there is no need for additional hole opening processing on the observation part 1, and the production and manufacturing requirements and cost requirements are low. It ensures that the observation part 1 has sufficient pressure resistance, which is conducive to extending the service life, and makes the liquid separation indicator device compact in structure and occupies little space. Finally, by setting the indicator tube 2 perpendicular to the horizontal plane, it can ensure smooth inflow and outflow of liquid, further ensure the accuracy of observation, and reduce the probability of eddy currents and turbulence, reduce the additional unstable load generated by the liquid on the tube wall, and help to further improve the service life.

[0031] Specifically, such as Figure 1-Figure 3 As shown, the inside of the observation section 1 is provided with no fewer than three indicator tubes 2, which are parallel to each other and form a group of three. It should be noted that the indicator tubes 2 can be spaced a certain distance apart or abutted against each other. Each indicator tube 2 in the same group is internally provided with an indicator mark 3. With this arrangement, if one indicator tube 2 errs due to impurities or damage to the indicator mark 3, the liquid dispensing status can be continuously observed through the other indicator tubes 2 in the group, reducing the probability of downtime for maintenance and ensuring work efficiency. Furthermore, damage can be promptly detected by observing the working conditions of the other indicator tubes 2, avoiding erroneous observations.

[0032] Specifically, such as Figure 1-Figure 3As shown, three groups of indicator tubes 2 are provided inside the observation portion 1, namely the first group 9, the second group 10, and the third group 11. The indicator mark 3 inside the first group 9 is the first indicator mark, the indicator mark 3 inside the second group 10 is the second indicator mark, and the indicator mark 3 inside the third group 11 is the third indicator mark. The first, second, and third indicators have the same volume but different densities, and the first, second, and third indicators have different colors. In the embodiment of the present utility model, the density of the first indicator mark is specifically set to be less than the density of the second indicator mark and less than the density of the third indicator mark, the density of the first indicator mark is less than the density of the upper liquid separation layer, the density of the second indicator mark is greater than the density of the upper liquid separation layer and less than the density of the lower liquid separation layer, and the density of the third indicator mark is greater than the density of the lower liquid separation layer. It should be noted that the density or color of the indicator mark 3 can be set according to the specific liquid separation process requirements. When the lower layer of separated liquid passes through the sight glass, the first indicator and the second indicator float on the top of the indicator tube 2, and the third indicator sinks to the bottom of the indicator tube 2. When the interface passes through the sight glass, the second indicator starts to move from top to bottom. When the second indicator sinks to the bottom of the indicator tube 2, it proves that the upper layer of separated liquid begins to flow through the sight glass. When the first indicator also sinks to the bottom of the indicator tube 2, it proves that all the liquid has been emptied. Through the above settings, the separation situation can be observed more accurately, further avoiding the occurrence of misjudgment, and when the separation and extraction of transparent liquids are carried out, the liquid flow situation can also be judged by the indicator 3, further improving work efficiency and applicability.

[0033] Specifically, such as Figure 2 As shown, the indicator tube 2 can be fixed to the inner side of the observation portion 1 by being attached to the inner wall of the observation portion 1 and adjacent indicator tubes 2 abutting against each other. The above setting process is simple and the cost is low. Adjacent indicator tubes 2 abut against each other to form grooves. The presence of the grooves can change the boundary layer structure of the fluid on the inner surface of the observation portion 1, and can further play a role in stabilizing the flow and suppressing eddies or turbulence, further avoiding the problems of stress fatigue and liquid energy loss of the observation portion 1 caused by eddies or turbulence, and effectively improving work safety and service life.

[0034] Specifically, such as Figure 3 As shown, the side wall of the observation portion 1 has a preset thickness, and the indicator tube 2 is formed by the opening of the side wall of the observation portion 1. The above arrangement has a better observation effect, makes the indication more intuitive and clear, and facilitates the operator to quickly understand the liquid dispensing situation.

[0035] Specifically, the indicator mark 3 is spherical, and its outer diameter is 0.5-0.7 times the inner diameter of the indicator tube 2. It should be noted that the indicator mark 3 can also be spindle-shaped, cylindrical, rectangular, etc. To reduce the difficulty of manufacturing and storage, it is preferably spherical. The indicator mark 3 is made of a non-reactive material such as glass or polytetrafluoroethylene. To facilitate observation in dim conditions, the indicator mark 3 is provided with a fluorescent material. Through the above configuration, if the outer diameter of the indicator mark 3 is less than 0.5 times the inner diameter of the indicator tube 2, the indicator mark 3 is too small, which is not conducive to observation. In addition, when the liquid level fluctuates greatly, the movement of the indicator mark 3 in the liquid becomes sensitive and unstable, which will cause fluctuations in the indication signal and reduce the stability of the liquid separation indication device. If the outer diameter of the indicator mark 3 is greater than 0.7 times the inner diameter of the indicator tube 2, the risk of the indicator mark 3 being blocked by impurities increases, increasing maintenance costs. Only by limiting the above relationship can the stability of the liquid separation observation process be further coordinated.

[0036] Specifically, the relationship between the height of the indicator tube 2, the height of the observation portion 1, and the inner diameter of the observation portion 1 satisfies the following equation: indicator tube 2 height: observation portion 1 height: observation portion 1 inner diameter = 1:1:(0.65-0.8). The above dimensional parameters are crucial. Setting the height of the observation portion 1 to be the same as the height of the indicator tube 2 facilitates installation and maintenance. Furthermore, the indicator tube 2 strengthens the observation portion 1, extending its service life. Finally, by defining the relationship between the inner diameter and height of the observation portion 1, the issue of increased flow resistance due to an overly long liquid flow path, which affects flow rate and delivery efficiency, and the issue of an overly narrow flow path, which makes it difficult to adapt to high-viscosity liquids, is resolved, effectively improving stability and applicability.

[0037] Specifically, such as Figure 4 As shown, the inner wall of the indicator tube 2 is symmetrically provided with V-shaped grooves 12. This arrangement can influence the flow state of the liquid in the indicator tube 2, suppressing eddies and turbulence. This not only ensures the stability of the indicator 3 during the observation process, but also prevents damage to the indicator 3 caused by excessive collisions with the indicator tube 2 due to eddies and turbulence. It also provides a guide path for impurities to flow out of the indicator tube 2, reducing the chance of the indicator 3 becoming blocked, further reducing maintenance costs, and improving work efficiency.

[0038] Specifically, a sealing ring is provided at the contact point between the first flange 5 and the observation part 1 and at the contact point between the second flange 6 and the observation part 1. The above arrangement can not only play a sealing role but also a shock absorbing role, further extending the service life of the liquid dispensing indicator device.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are exhaustively listed. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model.
