Description

Technical Field

[0001] The utility model relates to an improved device for detecting the amount of liquid in a thick liquid storage cylinder, and in particular to a novel structure of a device for detecting the amount of liquid in a thick liquid storage cylinder, which is superior to various common liquid amount detection structures in the thick liquid storage cylinder and can accurately measure the amount of thick liquid remaining in the cylinder at any time, is easy to repair and maintain, and requires less regular calibration. Background Art

[0002] The setting of the liquid storage cylinder is convenient for people to store reserved water or solution for use, and is convenient for the production of liquid storage cylinders that can be taken at any time. It is more particular than family or personal use. It is more important to connect the serial valve at the appropriate position of the liquid storage cylinder body to pipe the storage liquid and drain the liquid at any time, so as to ensure the timely and quantitative supply of the required processing liquid or chemical reaction liquid in continuous mass production. Since the input and output of mass production are very frequent, once there is a slight deviation in the monitoring of the reserves, it is very likely to cause a surge in the number of defective processed products that rely on the production liquid, resulting in losses due to increased production costs. Therefore, it is very important to accurately, conveniently and reliably detect the remaining amount of liquid in the liquid storage cylinder at all times, so as to grasp the correction at any time and ensure the supply of liquid at a regular and quantitative basis.

[0003] Generally, for a liquid storage cylinder that is almost sealed, with only a through-tube and a pouring or outlet, the simplest way to monitor the liquid level in the cylinder is to use a connecting tube connected to the bottom of the cylinder. Since the water level in the transparent connecting tube is aligned with the liquid level in the cylinder, the actual remaining liquid level in the cylinder can be visually observed at all times. However, this arrangement often causes the inner wall of the transparent connecting tube to become obscured by fluid friction or scale buildup after a period of use, making it difficult to clearly see the water level. Furthermore, many liquid storage cylinders used in production lines are specifically designed to store thick liquids, such as thick liquid storage cylinders that use a mixture of silica and water to form a thick liquid for processing. Due to the inherent viscosity of the thick liquid and its adhesion to the wall, the liquid in the cylinder rises and falls with the connected tube, making it less convenient and real-time than a linked one. Furthermore, the thick liquid will more severely abrade the transparent connecting tube, causing it to fail earlier. Therefore, the following three structures are commonly used to monitor the remaining thick liquid in the thick liquid storage cylinder.

[0004] A kind of Figure 1FIG. 1 shows a common capacitive device for detecting the amount of liquid in a thick liquid storage cylinder. Detection rods B1, B2, B3, and B4 are inserted at appropriate heights on the sidewall of the thick liquid storage cylinder 10. When any of the detection rods B1, B2, B3, and B4 is energized and the metal cylinder body is grounded, the remaining thick liquid 20 in the cylinder is contacted by the tips of the detection rods B1, B2, B3, and B4, and the capacitance value is measured. The capacitance value corresponding to the level of the thick liquid 20 is measured by the corresponding grounding of the detection rods B1, B2, B3, and B4. The capacitance value is converted by a computer to calculate the amount of thick liquid 20 in the cylinder. However, this structure has the disadvantage of only providing single-point detection and cannot measure capacitance at any time. If the detection probes B1 and B2 are located at the lower portion of the thick liquid storage cylinder 10, and B3 and B4 are located at the upper portion of the thick liquid storage cylinder 10, when the thick liquid 20 in the cylinder reaches the intermediate level Q2, the measured capacitance will be less accurate than the low level Q1 and the high level Q3. This is because the highest level of the liquid at this time is far from the detection probes B1, B2, B3, and B4. Therefore, this structure is not ideal.

[0005] Another example is Figure 2 As shown in FIG. 1 , a common continuous capacitance type device for detecting the amount of liquid in a thick liquid storage cylinder is provided. In the thick liquid storage cylinder 11, a series of stacked capacitor modules 31, 32, 33, 34 of electrical detectors 30 are suspended from the upper end. Each capacitor module 31, 32, 33, 34 also has a plurality of capacitor detection points 31A, 31B, 31C arranged in a series, thereby Figure 1 Compared with the structure, it can detect the continuous rise and fall of the amount of thick liquid 21 in the cylinder more real-timely, but its disadvantage is that it still cannot measure the finer capacity value, that is, it is impossible to grasp the detected amount of remaining thick liquid 21 in the cylinder more finely and accurately.

[0006] The third type Figure 3 As shown, a common gravimetric device for detecting the amount of liquid in a thick liquid storage cylinder is shown. A gravimetric device 40 is provided below the entire thick liquid storage cylinder 12. While the gravimetric device 40 can readily calculate the amount of the remaining thick liquid 22 in the thick liquid storage cylinder 12 based on the measured weight, a disadvantage is that it is necessarily provided below the entire thick liquid storage cylinder 12, closer to the ground and resulting in a narrow pressure drop compared to other locations on the thick liquid storage cylinder 12. This makes the device susceptible to moisture from the ground, making repair and maintenance difficult and requiring frequent regular calibration. Utility Model Content

[0007] In view of the various shortcomings of the common detection devices for the amount of residual thick liquid in the thick liquid storage cylinder, the applicant actively conceived a solution and, after many experiments and discussions, finally produced the present utility model.

[0008] Therefore, the present invention provides an improved device for detecting the amount of liquid in a thick liquid storage tank, comprising an inert gas supply tank, a pump, an outlet pressure probe, a pressure regulating valve, a speed regulating valve, an electronic pressure gauge, an artificial intelligence module, a programmable logic control module, a conversion value setting module, and a human-machine interface module with a value display. The outlet pressure probe is a T-shaped tube with three passages, one end of which is the longest and extends into the thick liquid storage tank to measure the bottom level of the liquid in the tank; the other end of the passage is inserted into the thick liquid storage tank and leads to the bottom of the tube. An electronic pressure gauge measures pressure at the air inlet; a bifurcated passage tube extends horizontally out of the thick liquid storage cylinder and connects to the inert gas supply tank via a speed regulating valve, a pressure regulating valve, and an air pump. The electronic pressure gauge's telecommunication output is then electrically connected to an artificial intelligence module, which converts the numerical settings to a programmable logic control module, and then electrically connected to a human-machine interface module to display the corresponding liquid level in the cylinder. This configuration allows for more accurate and timely measurement of the remaining thick liquid in the cylinder than conventional thick liquid storage cylinder liquid level detection structures, which is the primary purpose of the present invention.

[0009] The improved device for detecting the liquid level in a thick liquid storage tank primarily uses a tube extending from the top of the tank into the tank to measure the level of the liquid near the bottom of the tank, thereby obtaining the liquid level in the tank. This results in a pressure change value that allows inert gas to enter at a constant pressure and a fixed quantity, generating a small number of bubbles. This allows all components to be arranged around the top of the thick liquid storage tank, rather than in the low, narrow, and moisture-prone bottom space near the ground. This makes maintenance easier and reduces the need for regular calibration, which is another purpose of the present invention.

[0046] Please refer to Figure 4 , is a cross-sectional view of the improved device for detecting the amount of liquid in the thick liquid storage cylinder according to the present invention, which is installed in the thick liquid storage cylinder. Figure 4 As can be seen, the improved device 100 for detecting the amount of liquid in a thick liquid storage cylinder of the present invention comprises an inert gas supply tank 110, a pump 111, an outlet pressure probe 120, a pressure regulating valve 130, a speed regulating valve 140, an electronic pressure gauge 150, an artificial intelligence module 160, a programmable logic control module 170, and a human-machine interface module 180. The outlet pressure probe 120 is a T-shaped device that branches into three-way pipes 122, 123, and 124. The passage tube 122 at one end is the longest and extends into the thick liquid storage cylinder 13 close to the bottom level of the liquid in the cylinder. The passage tube 123 at the other end of the thick liquid storage cylinder 13 is connected to the pressure inlet port 151 of the electronic pressure gauge 150. The forked passage tube 124 extends horizontally out of the thick liquid storage cylinder 13 and is connected to the speed regulating valve 140, the pressure regulating valve 130, the pump 111, and the inert gas supply tank 110. It is then connected to the telecommunication port 151 of the electronic pressure gauge 150. Output terminal 152 is electrically connected to artificial intelligence module 160 to receive a potential signal, which is then converted to a numerical setting by programmable logic control module 170 and then electrically connected to human-machine interface module numerical display 180 to display the corresponding liquid level in the cylinder (e.g., cylinder capacity or liquid level). The speed regulating valve 140 comprises an adjustable diameter valve element 141 and a parallel check valve 142. Furthermore, to facilitate rapid and complete downward discharge of liquid from the thick liquid storage cylinder 13, a recessed hopper volume 13A is formed downward from the lowest horizontal level of the liquid measurement cylinder 13, as shown in the figure by the trapezoidal cross-section of the remaining thick liquid 23. Therefore, when the gas is discharged from the outlet of the passage tube 122, the amount of thick liquid 23 measured by the pressure probe must be added to the recessed hopper volume 13A. Even when the measured amount of thick liquid 23 drops to the lowest pressure value and is just displayed as zero, this bottom recessed hopper volume 13A still exists. This is explained here.

[0047] Therefore, if Figure 5 As shown, as the amount of thick liquid 23 remaining in the cylinder rises and falls during the process of replenishment or drainage, the liquid sediment pressure obtained by multiplying the density of the thick liquid 23 by the liquid sediment height will also change accordingly. This is reflected in the resistance back pressure at the outlet of the passage tube 122, that is, the resistance back pressure of the fine bubble blowing will also change accordingly. The electronic pressure gauge 150 reads the corresponding pressure contrast potential value of the different stored volumes. An example test is as follows:

[0048] A thick liquid 23 of a specific specific gravity is stored in the cylinder. A pressure regulating valve 130 is used to adjust the nitrogen input pressure to a maximum value not exceeding 0.204 kg / cm². A speed regulating valve 140 is also used to control the nitrogen delivery rate to approximately 1-50 cc / min. Avoid excessive jetting. Instead, an inert gas (e.g., nitrogen) is first introduced from the source into the outlet pressure probe 120 at a constant flow rate and pressure. A small amount of bubbles is then generated from the passage pipe 122 and squeezed into the thick liquid 23 in the cylinder. Depending on the amount of thick liquid 23 in the cylinder, the exact pressure readings from the electronic pressure gauge 150 corresponding to the volume are as shown in the following table:

[0049]

[0050]

[0051] In addition, if Figure 6 FIG. 1 shows an embodiment of the present invention. The outlet pressure probe tube 121 extends into the thick liquid storage cylinder 13 close to the bottom level of the liquid in the cylinder for measuring the liquid. Unlike the straight extension shown in the previous figure, the passage tube 122 can also be extended obliquely into the thick liquid storage cylinder 13 close to the bottom level of the liquid in the cylinder for measuring the liquid, which is equally effective.

[0052] Thus, in summary, the improved device for detecting the amount of liquid in a thick liquid storage cylinder of the present invention is indeed more capable of accurately measuring the amount of thick liquid remaining in the cylinder at any time than various common thick liquid storage cylinder liquid amount detection structures, and is easy to repair and maintain, requiring less regular calibration. Of course, the detection is not limited to the thick liquid 23, and the amount of non-viscous liquids such as pure water stored in the cylinder can also be set to be measured.

[0053] like Figure 7 As shown in FIG. 1 , another embodiment of the present invention, the end passage tube 122 is the longest and extends into the thick liquid storage cylinder 13 close to the bottom level of the measuring cylinder liquid, and penetrates from the side wall of the thick liquid storage cylinder 13; Figure 8 As shown in the figure, it is another embodiment, the end passage tube 122 is the longest, and extends into the thick liquid storage cylinder 13 close to the bottom level of the liquid in the measuring cylinder, and is bent back and penetrated from the bottom wall of the thick liquid storage cylinder 13. Figure 7 or Figure 8 The access tube 122 is initially positioned outside the thick liquid reservoir 13, then curved and inserted into the reservoir 13 to measure the lowest level of the liquid in the reservoir. The pressure differential detection performance is naturally affected by the resistance of the curved tube, unlike straight or oblique extensions. In this case, the output value of the telecommunications output terminal 152 can be adjusted based on actual on-site conditions.

[0054] The above description is only a preferred specific embodiment of the present invention. If the changes made based on the concept of the present invention, or the functional effects produced therefrom, do not exceed the spirit contained in this specification and illustrations, they shall fall within the scope of protection of the present invention and are hereby declared.
