Description
Technical Field
[0001] The utility model relates to an improved structure of a liquid storage graduated cylinder for detecting the storage amount of a high-fluidity liquid, and in particular to an improved structure of a liquid storage graduated cylinder for detecting the storage amount of a high-fluidity liquid, which can more accurately measure the amount of liquid remaining in the cylinder at any time, is easy to repair and maintain, and reduces the need for regular calibration. Background Art
[0002] People store water or solutions reserved for use in cylinders, and cylinders that are convenient for frequent use in production and manufacturing are more particular than those for home or personal use. It is more important to connect the pipe and the valve at the appropriate position of the cylinder body to inject the stored liquid and drain the liquid at all times, 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 so 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 cylinder at all times so that corrections can be made at any time to ensure the timely and quantitative supply of liquid. Therefore, there are reserve measuring cylinders that can detect the remaining liquid in the cylinder. The most common liquids stored in the cylinder are non-viscous liquids such as water or acidic dilute concentration mixtures and other highly fluid liquids.
[0003] Generally, for a nearly airtight tank-shaped storage liquid storage cylinder with only a through-tube and a liquid filling or liquid outlet, the device attached thereto for constantly detecting the liquid level in the cylinder is the simplest one. The structure adopts a connecting tube structure with a bottom pipe connected to the liquid storage cylinder. By aligning the water level in the transparent connecting tube with the liquid level in the liquid storage cylinder, the actual remaining liquid level in the cylinder can be visually observed at all times. However, this arrangement often causes the transparent connecting tube to become obscured by friction between the tube wall and the wall due to scale stuck on the tube wall after a period of use, making it impossible to clearly see the water level. Therefore, the existing detection of the remaining high-fluidity liquid in the high-fluidity liquid storage cylinder has been replaced by the following several types of reserve graduated cylinder structures.
[0004] A kind of Figure 1As shown, a capacitance-type liquid storage cylinder for detecting the amount of liquid in a high-flow liquid storage cylinder is provided. Detection rods B1, B2, B3, and B4 are inserted one by one at appropriate heights on the side wall of the cylinder body 10. When any detection rod B1, B2, B3, or B4 is energized and the metal cylinder body is grounded, the capacitance value of the remaining high-flow liquid 20 in the cylinder can be measured by the tip of the detection rod B1, B2, B3, or B4. The capacitance value of the high-flow liquid 20 is measured by the corresponding amount of high-flow liquid 20. Computer conversion can be used to calculate the amount of high-flow liquid 20 in the cylinder. The disadvantage of this structure is that it can only detect at a single point and cannot measure capacitance at any time. As shown in the figure, if the detection rods B1 and B2 are concentrated at the lower position of the cylinder 10, and B3 and B4 are concentrated at the upper position of the cylinder 10, when the amount of high-flow liquid 20 stored in the cylinder is at the intermediate liquid level Q2, the measured capacitance will be less accurate than the low liquid level Q1 and the high liquid level Q3. This is because the highest liquid level at these locations is far away from the detection rods B1, B2, B3, and B4, making this structure undesirable.
[0005] Another example is Figure 2 As shown, a liquid storage measuring cylinder for continuous capacitive detection of the amount of liquid in the liquid cylinder with high fluidity is provided. In the cylinder body 11, a string 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 is also closely packed with several capacitor probes 31A, 31B, 31C. Figure 1 The structure can detect the continuous rise and fall of the amount of the high-flow liquid 21 in the cylinder more real-timely, but its disadvantage is that it still cannot measure a finer capacity value, and thus cannot grasp the remaining amount of the high-flow liquid 21 in the cylinder more finely and accurately.
[0006] The third type is Figure 3 As shown, a liquid storage graduated cylinder for detecting the amount of liquid in the cylinder storing high-fluidity liquid by gravimetric means is provided below the cylinder body 12. Although a gravimetric device 40 can be used to calculate the amount of the remaining high-fluidity liquid 22 in the cylinder body 12 at any time based on the measured weight, a disadvantage is that it must be provided below the entire cylinder body 12, which is closer to the ground pressure drop and narrow space relative to other parts of the cylinder body 12, and is easily affected by moisture from the ground, which often makes repair and maintenance difficult and requires frequent regular calibration. Utility Model Content
[0007] In view of the various defects of various existing liquid storage measuring cylinders for detecting the amount of high-flow liquid, the utility model provides an improved structure of a liquid storage measuring cylinder for detecting the storage of high-flow liquid. The structure mainly consists of a cylinder, a double-ended vent pipe, and a pressure gauge. One end of the double-ended vent pipe is tightly connected to the pressure inlet end of the pressure gauge without any air leakage gap. Then, the other end of the double-ended vent pipe is connected to the pressure gauge and inserted into the lower layer of the liquid storage space in the cylinder from an appropriate position of the cylinder. In particular, the pressure gauge is exposed at the top of the cylinder and is suspended and fixed to the top of the cylinder. The pressure value obtained by the pressure gauge can be directly read and converted and compared to obtain the current actual liquid storage amount in the cylinder. Compared with the existing storage measuring cylinder structures for detecting the storage of various high-flow liquids, the structure can more accurately measure the liquid storage amount in the cylinder at any time.
[0008] The improved structure of the liquid storage measuring cylinder for detecting the storage amount of high-flow liquid provided by the utility model mainly uses a tube extending from the top of the cylinder into the cylinder to obtain the amount of liquid in the cylinder. When the tube mouth inserted into the lower layer of the liquid storage space in the cylinder is immersed in the cylinder at night, the enclosed gas in the tube is formed to sense the pressure change of the liquid amount. Therefore, all the components can be arranged around the top of the cylinder and are not arranged in the narrow and moisture-prone bottom space near the ground, so that the cylinder is easy to repair and maintain and requires less regular calibration.
[0009] Furthermore, the improved structure of the liquid storage measuring cylinder for detecting the storage amount of high-flow liquid provided by the present invention can not only directly read the pressure value obtained by the pressure gauge and convert and compare the current actual liquid storage amount in the cylinder, but if the pressure gauge is a digital electronic pressure gauge with a digital value output terminal, it can also be expanded from its digital value output terminal to external digital monitoring equipment and automatic control of liquid inlet and outlet equipment, thereby facilitating the full promotion of automation of liquid transportation and temporary storage operation lines.

[0038] Figure 4The improved structure of the liquid storage graduated cylinder for detecting the storage amount of high-flow liquid of the utility model is installed in a cross-sectional view of the liquid storage graduated cylinder for detecting the storage amount of high-flow liquid of the utility model. As shown in the figure, the improved structure of the liquid storage graduated cylinder 100 for detecting the storage amount of high-flow liquid provided by the utility model mainly consists of a cylinder 110, a double-ended venting tube 120, and a pressure gauge 130. The double-ended venting tube 120 is tightly connected to the pressure inlet end 131 of the pressure gauge 130 without leaving any gap for air leakage, and then the double-ended venting tube is connected to the pressure inlet end 131 of the pressure gauge 130. The other end of the pipe mouth of the pressure gauge 130 120 is inserted into the lower layer of the liquid storage space in the cylinder 110 from the appropriate position of the cylinder 110, and the pressure gauge 130 is exposed to the top of the cylinder 110, and is suspended and fixed with the top of the cylinder 110. As shown in the figure, the other end of the pipe mouth of the double-ended vent pipe 120 is inserted into the lower layer of the liquid storage space in the cylinder 110 from the appropriate position of the cylinder 110, which is the top wall 111 of the cylinder 110, so that the double-ended vent pipe 120 is inserted downward and extends into the lower layer of the liquid storage space in the cylinder.
[0039] In terms of function, since the double-ended vent tube 120 is inserted into the lower layer of the liquid storage space in the cylinder 110, and the tube mouth is immersed in the liquid in the cylinder, forming an inverted insertion posture of the tube with one end of the pressure gauge 130 closed, the gas enclosed in the double-ended vent tube 120 can sense the pressure change value of the liquid volume, so that the amount of high-flowability liquid 23 retained in the cylinder 110 can change with the filling or discharge process. The liquid deposition pressure obtained by multiplying the density of the high-flowability liquid 23 and the liquid deposition height will also change accordingly, pushing the closed gas in the tube, so that the pressure gauge 130 can directly display the pressure value of the corresponding remaining liquid volume in the cylinder. This value By comparing and converting the values, the capacity of the high-flowability liquid 23 in the cylinder 110 at this time can be obtained. Even if the high-flowability liquid 23 in the cylinder 110 is completely emptied, that is, in the state of zero liquid volume and zero water pressure, the high-flowability liquid 23 is subsequently injected into the cylinder. Because the end of the tube connected to the pressure gauge 130 is still closed, the air in the tube remains in the tube and cannot be discharged upward. As a result, the high-flowability liquid 23 cannot occupy the space in the tube, and the air in the tube still maintains the function of sensing the pressure change of the liquid volume. In addition, experimental measurements show that when the cylinder 110 of a normal capacity is filled with high-flowability liquid 23, the water pressure generated is at most 0.11 kg / cm 2 , it is not enough to forcefully squeeze in and greatly compress and burst the air in the tube, so it is indeed usable. In terms of use, it is best to use pure water or a high-flow liquid 23 of appropriately pure water in the measuring tube. If it is changed to a mixed supply liquid with viscosity, it will cause the inner and outer walls of the tube mouth where the liquid in the tube is inserted to accumulate thick scale, causing increased maintenance and cleaning troubles. Therefore, the high-flow liquid 23 that should be stored in the tube cannot be used.
[0040] The utility model can be Figure 5The method shown is implemented, the other end of the vent pipe 120 is connected to the pressure gauge 130 and is inserted from the top wall 111 of the cylinder 110 downwardly into the lower layer of the liquid storage space in the cylinder. The tube body section 121 inserted into the cylinder is different from the straight insertion as shown in the previous figure. The tube body section 121 can also be inserted obliquely into the lower layer of the liquid storage space in the cylinder 110, which is equally effective.
[0041] The other end of the double-ended vent pipe 120 connected to the pressure gauge 130 is connected to the appropriate position of the cylinder 110. Figure 6 As shown, the appropriate position can also be the bottom wall 112 of the cylinder 110, so that the double-ended ventilation pipe 120 is directly bent and turned to extend from the bottom into the lower layer of the liquid storage space in the cylinder, or as Figure 7 As shown, the appropriate position may also be the bottom 113 of the side wall of the cylinder 110, so that the double-ended vent pipe 120 bends and extends from one side bottom of the cylinder into the lower layer of the liquid storage space in the cylinder.
[0042] The utility model can also be Figure 8 By implementing in the manner shown, in addition to being able to directly read the pressure value obtained by the pressure gauge 130 and convert and compare the current actual liquid storage volume in the cylinder 110, if the pressure gauge 130 is a digital electronic pressure gauge with a digital value output terminal 132, it can also be expanded from its digital value output terminal 132 to an external digital monitoring device 200 and an automatic liquid inlet and outlet control device 300, thereby facilitating the full automation of the liquid transportation and temporary storage operation line.
[0043] As can be seen from the above, the improved structure of the liquid storage measuring cylinder for detecting the reserve of high-fluidity liquid provided by the utility model can more accurately measure the remaining liquid amount in the cylinder at any time than the existing reserve measuring cylinder structures for detecting the reserve of various high-fluidity liquids, and is easy to repair and maintain, and requires less regular calibration.
[0044] The embodiments described above are merely illustrative descriptions of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the present invention.
