Description

Technical Field

[0001] The present invention relates to the technical field of flowmeters, and more specifically, to a magnetic impurity removal device for an electromagnetic flowmeter and a method of using the device. Background Art

[0002] The electromagnetic flowmeter is a new type of flow measurement instrument that developed rapidly in the 1950s and 1960s with the development of electronic technology. It is based on Faraday's law of electromagnetic induction and is suitable for the detection of flow of various conductive liquids such as water, sewage, acid, alkali, salt solution, slurry, etc.

[0003] In the prior art, the electromagnetic flowmeter is mainly composed of a magnetic circuit system, a measuring tube, electrodes, a casing, a lining and a converter. The working principle is as follows: when a conductive liquid passes through a magnetic field, the charged particles in the liquid will be affected by the magnetic field, thereby generating an induced electromotive force in a direction perpendicular to the magnetic field and the flow rate. This induced electromotive force is proportional to the flow rate of the liquid. By measuring this electromotive force, the flow rate of the conductive liquid can be calculated.

[0004] However, there are many types of conductive liquids for flow detection by electromagnetic flowmeters. If some conductive liquids contain magnetic impurities, such as rust, metal or other magnetic particles, these impurities may be adsorbed on the electrodes of the electromagnetic flowmeter under the action of the magnetic field, thereby affecting the measurement accuracy of the electromagnetic flowmeter.

[0005] If some conductive liquids (such as mud) contain not only magnetic impurities but also magnetic solid particles, then the existing magnetic attraction mechanism cannot achieve a targeted magnetic attraction effect, resulting in the solid particles and magnetic impurities being adsorbed at the same time, thereby reducing the flow rate of the solid particles and affecting the measurement value of the conductive liquid. For this reason, a magnetic impurity removal device for an electromagnetic flowmeter and a method of using the device are proposed to improve the existing problems. Summary of the invention

[0010] The present invention is further configured as follows: a cavity is opened in the adsorption disk, the end of the fixed axis away from the second vertical plate can penetrate the side wall of the adsorption disk away from the stepping motor and extend into the cavity, the fixed axis and the micro telescopic rod are vertically distributed, and the micro telescopic rod and the magnetic suction part are both located in the cavity.

[0011] The present invention is further configured as follows: an adsorption groove is provided on the outer wall in the circumferential direction of the adsorption disk, and partition blocks are evenly arranged in the adsorption groove; through grooves are evenly provided on the outer wall in the circumferential direction of the adsorption pipe, and the adsorption disk can be plugged into the corresponding through grooves.

[0012] The present invention is further configured as follows: the magnetic attraction component includes a first electric magnetic block, a second electric magnetic block arranged on one side of the first electric magnetic block, and a third electric magnetic block arranged on a side of the second electric magnetic block away from the first electric magnetic block; the first electric magnetic block, the second electric magnetic block and the third electric magnetic block are all arc-shaped; the telescopic end of the micro telescopic rod is connected to the bottom of the second electric magnetic block.

[0016] A magnetic impurity removal method for an electromagnetic flowmeter, using the magnetic impurity removal device for an electromagnetic flowmeter as described above, comprises the following steps: S1. Before the flow rate of the conductive liquid is detected, the conductive liquid first enters the adsorption pipe. During this process, the magnetic suction part is activated to adsorb the magnetic impurities passing through the adsorption plate, so that the magnetic impurities are adsorbed on a certain surface of the adsorption plate; S2. When the magnetic impurities on a certain part of the surface of the adsorption disk accumulate to the maximum capacity, the stepper motor starts, driving the adsorption disk to rotate synchronously along the flow direction of the conductive liquid, so that the magnetic impurities on a certain part of the surface of the adsorption disk are away from the magnetic suction part and fall out of the adsorption pipe through rotation, while the surface of another part of the adsorption disk will enter the adsorption pipe, and the magnetic impurities passing through the adsorption disk will be adsorbed again, and the cycle is repeated; S3. Subsequently, the adsorbed conductive liquid continues to be transported to the gathering pipe and moves along the distribution direction of the gathering pipe. At this time, since the flow rate of the conductive liquid slows down, it is not easy to carry the bubbles forward, and the bubbles float up due to gravity, so the bubbles will gather at the top of the inner wall of the middle end of the gathering pipe; S4. During the working process of S3, the bubbles in the conductive liquid will enter the debubble box and gradually fill the debubble box. With the entry of bubbles, the liquid level of the conductive liquid in the debubble box drops, and the floating plate loses buoyancy and starts to drop. At the same time, the movable rod and the sealing plate are displaced synchronously, so that the spring changes from a horizontal state to a bent state, and the sealing plate no longer closes the debubble tube, thereby allowing the bubbles to be discharged through the debubble tube; S5. As the bubbles are discharged, the conductive liquid will re-enter the debubble box, push the floating plate to move upward, and push the movable rod and the sealing plate to rise synchronously, so that the sealing plate and the debubble tube fit tightly, and the debubble tube is closed. At this time, the conductive liquid can only be in the debubble box and will not leak. The spring changes from a bent state to a horizontal state; this cycle is repeated; S6. The conductive liquid continues to enter the transition pipe and the detection pipe, and the flow rate is detected by the electromagnetic flowmeter in the detection pipe, and then enters the next pipe through the delivery pipe.

[0017] In summary, the present application includes at least one of the following beneficial technical effects: (1) The magnetic impurities passing through the adsorption disk are adsorbed by the magnetic suction component, so that the magnetic impurities are adsorbed on a certain part of the surface of the adsorption disk; when the magnetic impurities on a certain part of the surface of the adsorption disk accumulate to the maximum capacity, the stepper motor drives the adsorption disk to rotate synchronously along the flow direction of the conductive liquid, so that the magnetic impurities on a certain part of the surface of the adsorption disk are away from the magnetic suction component and fall out of the adsorption pipe through rotation, while the surface of another part of the adsorption disk will enter the adsorption pipe, and the magnetic impurities passing through the adsorption disk will be adsorbed again, and this cycle is repeated; thereby improving the measurement accuracy of the electromagnetic flowmeter.

[0018] (2) The bubbles in the conductive liquid will enter the debubble box and gradually fill it up. As the bubbles enter, the conductive liquid level in the debubble box drops, and the floating plate loses buoyancy and begins to drop. At the same time, the movable rod and the sealing plate move synchronously, causing the spring to change from a horizontal state to a bent state. The sealing plate no longer closes the debubble tube, allowing the bubbles to be discharged through the debubble tube. This improves the measurement accuracy of the electromagnetic flowmeter and ensures the accuracy of the flow measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] See also Figure 1-Figure 8 , the present invention provides the following technical solutions: Example 1, see Figure 1-Figure 8A magnetic impurity removal device for an electromagnetic flowmeter comprises a pipeline component 1, an adsorption component 2 and a defoaming component 3; wherein the pipeline component 1 is used to transport the conductive liquid and detect the flow rate of the conductive liquid during the transport process; and the adsorption component 2 is used to specifically adsorb the magnetic impurities in the conductive liquid with solid particles, so that when the magnetic impurities are adsorbed, the flow rate of the conductive liquid with solid particles is not interfered, on the one hand, the problem that the magnetic impurities may be adsorbed on the electrodes of the electromagnetic flowmeter under the action of the magnetic field is avoided, thereby improving the measurement accuracy of the electromagnetic flowmeter; on the other hand, the problem that the existing magnetic attraction mechanism cannot achieve a targeted magnetic attraction effect, resulting in the simultaneous adsorption of the solid particles and the magnetic impurities, thereby ensuring the flow rate of the solid particles, which is beneficial to the measurement value of the conductive liquid.

[0030] The function of the debubble component 3 is to eliminate bubbles in the conductive liquid so that the bubbles are discharged through the debubble component 3, thereby avoiding the problem that the presence of bubbles will cause distortion of the induced electromotive force and affect the accuracy of flow measurement, thereby improving the measurement accuracy of the electromagnetic flowmeter and ensuring the accuracy of flow measurement.

[0031] See also Figure 1 Specifically, the pipeline assembly 1 includes a base plate 11, an adsorption pipeline 12 arranged above the base plate 11, a gathering pipeline 13 arranged at one end of the adsorption pipeline 12, a transition pipeline 14 arranged at an end of the gathering pipeline 13 away from the adsorption pipeline 12, a detection pipeline 15 arranged at an end of the transition pipeline 14 away from the gathering pipeline 13, an electromagnetic flowmeter 16 arranged on the top of the detection pipeline 15, and a conveying pipeline 17 arranged at an end of the detection pipeline 15 away from the transition pipeline 14.

[0032] Before the flow rate of the conductive liquid is detected, the conductive liquid first enters the adsorption pipe 12 to adsorb and remove the magnetic impurities passing through the adsorption pipe 12; then it enters the gathering pipe 13 to eliminate bubbles, and finally enters the detection pipe 15 through the transition pipe 14. The electromagnetic flowmeter 16 is started to detect the flow rate of the conductive liquid passing through, and then it is sent away through the delivery pipe 17.

[0033] See also Figure 2-Figure 5 Specifically, the adsorption component 2 is arranged on the top of the bottom plate 11, and includes a base tube 21, a first vertical plate 22 uniformly arranged on the inner wall of the base tube 21 in the circumferential direction, a stepper motor 23 arranged on one side of the first vertical plate 22, an adsorption disk 24 arranged at the output end of the stepper motor 23, a second vertical plate 25 arranged on the side of the adsorption disk 24 away from the stepper motor 23, a fixed shaft 26 arranged on the side wall of the second vertical plate 25, a miniature telescopic rod 27 arranged on the outer wall of the fixed shaft 26, and a magnetic suction member 28 arranged at the telescopic end of the miniature telescopic rod 27; the magnetic suction member 28 is used to adsorb metal impurities in the mud.

[0034] Before the flow rate of the conductive liquid is detected, the conductive liquid first enters the adsorption pipe 12 . During this process, the magnetic suction component 28 is activated to adsorb the magnetic impurities passing through the adsorption disk 24 , so that the magnetic impurities are adsorbed on a certain surface of the adsorption disk 24 .

[0035] When the magnetic impurities on a certain part of the surface of the adsorption disk 24 accumulate to the maximum capacity, the stepper motor 23 starts, driving the adsorption disk 24 to rotate synchronously along the flow direction of the conductive liquid, so that the magnetic impurities on a certain part of the surface of the adsorption disk 24 are away from the magnetic suction member 28 and fall to the outside of the adsorption pipe 12 through rotation, while the surface of another part of the adsorption disk 24 will enter the adsorption pipe 12, and the magnetic impurities passing through the adsorption disk 24 will be adsorbed again, and the cycle is repeated; thereby avoiding the problem that the magnetic impurities may be adsorbed on the electrodes of the electromagnetic flowmeter under the action of the magnetic field, thereby improving the measurement accuracy of the electromagnetic flowmeter.

[0036] See also Figure 6-Figure 8 Specifically, the debubble assembly 3 is arranged at the top of the gathering pipe 13, and includes a debubble box 31, a debubble tube 32 arranged in the debubble box 31, a sealing plate 33 arranged in the debubble box 31, a movable rod 34 arranged at one end of the sealing plate 33, a floating plate 35 arranged below the movable rod 34, and a spring 36 sleeved on the debubble tube 32 and the movable rod 34.

[0037] Among them, the bubbles in the conductive liquid will enter the debubble box 31 and gradually fill the debubble box 31. As the bubbles enter, the liquid level of the conductive liquid in the debubble box 31 drops, and the floating plate 35 loses buoyancy and begins to drop. At the same time, the movable rod 34 and the sealing plate 33 are displaced synchronously, so that the spring 36 changes from a horizontal state to a bent state, and the sealing plate 33 no longer closes the debubble tube 32, thereby allowing the bubbles to be discharged through the debubble tube 32; as the bubbles are discharged, the conductive liquid will re-enter the debubble box 31, push the floating plate 35 to move upward, and push the movable rod 34 and the sealing plate 33 to rise synchronously, so that the sealing plate 33 and the debubble tube 32 fit tightly, and the debubble tube 32 is closed. At this time, the conductive liquid can only be in the debubble box 31 and will not leak. The spring 36 changes from a bent state to a horizontal state, and the cycle is repeated; the bubbles in the conductive liquid can be eliminated, so that the bubbles are discharged through the debubble assembly 3, avoiding the problem that the existence of bubbles will cause the induced electromotive force to be distorted and affect the accuracy of flow measurement, thereby improving the measurement accuracy of the electromagnetic flowmeter and ensuring the accuracy of flow measurement.

[0038] See also Figure 1Furthermore, support plates 18 are symmetrically arranged on the top of the bottom plate 11, wherein the top of one support plate 18 is connected to the outer wall of the transition pipe 14, and the top of the other support plate 18 is connected to the outer wall of the conveying pipe 17, and the gathering pipe 13 is in the shape of a curved pipe.

[0039] Among them, the adsorbed conductive liquid continues to be transported to the gathering pipe 13. Since the gathering pipe 13 is a curved pipe, the conductive liquid will slow down when flowing in the oblique upward direction along the gathering pipe 13, and it is not easy to carry bubbles forward. Due to the gravity factor, the bubbles float up, so the bubbles will gather at the top of the inner wall of the middle end of the gathering pipe 13.

[0040] When the conductive liquid flows obliquely downward along the gathering pipe 13 , the flow velocity is increased, thereby ensuring the accuracy of the flow velocity of the conductive liquid.

[0041] See also Figure 2-Figure 5 Furthermore, both ends of the base tube 21 are open, the output end of the stepper motor 23 passes through the side wall of the first vertical plate 22 and is connected to one side wall of the adsorption disk 24, one end of the second vertical plate 25 is connected to the inner wall of the base tube 21, and the fixed shaft 26 is distributed on one side of the second vertical plate 25 close to the adsorption disk 24, and the fixed shaft 26 is aligned with the output shaft of the stepper motor 23.

[0042] See also Figure 2-Figure 5 Furthermore, a cavity 241 is opened in the adsorption disk 24, and the end of the fixed shaft 26 away from the second vertical plate 25 can penetrate the side wall of the adsorption disk 24 away from the stepping motor 23 and extend into the cavity 241. The fixed shaft 26 and the micro telescopic rod 27 are vertically distributed, and the micro telescopic rod 27 and the magnetic suction member 28 are both located in the cavity 241.

[0043] Among them, since the fixed shaft 26 is distributed on the side of the second vertical plate 25 close to the adsorption disk 24, the fixed shaft 26 is aligned with the output shaft of the stepper motor 23, and the end of the fixed shaft 26 away from the second vertical plate 25 can penetrate the side wall of the adsorption disk 24 away from the stepper motor 23 and extend into the cavity 241. Therefore, when the adsorption disk 24 rotates, the fixed shaft 26, the micro telescopic rod 27 and the magnetic suction component 28 will not rotate, and will not interfere with the adsorption of magnetic impurities by the magnetic suction component 28, so that the magnetic suction component 28 always remains in the cavity 241 and close to the position of the adsorption pipe 12.

[0044] See also Figure 2-Figure 5 Furthermore, an adsorption groove 242 is formed on the outer wall of the adsorption plate 24 in the circumferential direction, and partition blocks 243 are evenly arranged in the adsorption groove 242; through grooves 121 are evenly formed on the outer wall of the adsorption pipe 12 in the circumferential direction, and the adsorption plate 24 can be inserted into the corresponding through grooves 121.

[0045] Among them, through the design of the dividing block 243 and the adsorption groove 242, when the adsorption plate 24 rotates in the through groove 121, the corresponding two dividing blocks 243 will be distributed at both ends of the through groove 121 to block and close the through groove 121; when the adsorption groove 242 located between the two dividing blocks 243 adsorbs the magnetic impurities to the maximum capacity, the stepper motor 23 is started to drive the adsorption plate 24 to rotate synchronously along the flow direction of the conductive liquid, so that the magnetic impurities in the corresponding adsorption groove 242 are away from the magnetic suction part 28 and fall to the outside of the adsorption pipe 12 through rotation; in this process, since the magnetic impurities have accumulated to the maximum capacity, the probability of conductive liquid overflow can be reduced during rotation.

[0046] See also Figure 2-Figure 5 Furthermore, the magnetic component 28 includes a first electric magnetic block 281, a second electric magnetic block 282 arranged on one side of the first electric magnetic block 281, and a third electric magnetic block 283 arranged on a side of the second electric magnetic block 282 away from the first electric magnetic block 281; the first electric magnetic block 281, the second electric magnetic block 282 and the third electric magnetic block 283 are all arc-shaped; the telescopic end of the micro telescopic rod 27 is connected to the bottom of the second electric magnetic block 282.

[0047] Among them, the micro telescopic rod 27 is started, and its telescopic end drives the second electric magnetic block 282, the first electric magnetic block 281 and the third electric magnetic block 283 to approach or move away from the adsorption pipe 12 in the cavity 241, so that the magnetic attraction strength of the magnetic impurities can be adjusted by adjusting the distance between the second electric magnetic block 282, the first electric magnetic block 281 and the third electric magnetic block 283 and the adsorption pipe 12, thereby avoiding the problem that the existing magnetic attraction mechanism cannot achieve a targeted magnetic attraction effect, resulting in the simultaneous adsorption of the self-carried solid particles and the magnetic impurities, thereby ensuring the flow rate of the self-carried solid particles, which is beneficial to the measurement value of the conductive liquid.

[0048] It should be noted that although the solid particles carried by the object are magnetic, the magnetism is smaller than that of the magnetic impurities. Therefore, when the magnetic impurities are adsorbed, the flow rate of the solid particles carried by the object is not interfered.

[0049] Embodiment 2: Through the technical solution of embodiment 1, although the problem in the prior art that impurities may be adsorbed on the electrodes of the electromagnetic flowmeter under the action of the magnetic field, thereby affecting the measurement accuracy of the electromagnetic flowmeter, and the existing magnetic attraction mechanism cannot achieve a targeted magnetic attraction effect, resulting in the problem that the solid particles and magnetic impurities are adsorbed at the same time; however, the problem that bubbles in the conductive liquid will cause the induced electromotive force to be distorted and affect the accuracy of flow measurement is still not solved. For this reason, the following solution is proposed: See also Figure 6-Figure 8Furthermore, a cavity 311 is provided in the debubble box 31, an inlet 312 is provided at the bottom of the debubble box 31, the cavity 311 and the inlet 312 are connected, a connecting port 131 is provided on the outer wall of the gathering pipe 13, the inlet 312 can be connected to the connecting port 131, and pointed tips 313 are evenly arranged on the inner wall of the inlet 312, and the pointed tips 313 are distributed obliquely downward.

[0050] The bubbles in the conductive liquid will enter the cavity 311 through the connection port 131 and the inlet 312; in this process, since the pointed tip 313 is tilted downward, the pointed tip 313 will puncture some bubbles, which is conducive to the rapid discharge of gas and bubbles.

[0051] See also Figure 6-Figure 8 Furthermore, both ends of the debubble tube 32 are open, one end of the debubble tube 32 can pass through the side wall of the debubble box 31 and extend outside the debubble box 31, the sealing plate 33 and the movable rod 34 are located at the end of the debubble tube 32 away from the debubble box 31, one end of the spring 36 is sleeved on the debubble tube 32, and the other end is sleeved on the movable rod 34, and the sealing plate 33 is located in the spring 36.

[0052] See also Figure 6-Figure 8 Furthermore, a floating groove 351 is provided on the top of the floating plate 35, and a stopper 352 is provided in the floating groove 351. The stopper 352 is vertically distributed with the floating groove 351, and both ends of the stopper 352 are connected to the inner wall of the floating groove 351. The movable rod 34 is away from the outer wall of the sealing plate 33 and is inserted into the floating groove 351 and is located below the stopper 352.

[0053] Among them, when the floating plate 35 loses buoyancy and begins to descend, since the movable rod 34 is away from the outer wall of the sealing plate 33 and is inserted in the floating groove 351 and is located below the stop block 352, the floating plate 35 will drive the stop block 352 to descend synchronously, and pull the movable rod 34 and the sealing plate 33 to descend synchronously, so that the spring 36 changes from a horizontal state to a bent state, and the sealing plate 33 is away from the debubble tube 32 and no longer closes the debubble tube 32, thereby allowing bubbles to be discharged through the debubble tube 32; the existence of bubbles can avoid causing the induced electromotive force to be distorted, affecting the accuracy of flow measurement, thereby improving the measurement accuracy of the electromagnetic flowmeter and ensuring the accuracy of flow measurement.

[0054] Embodiment 3, a magnetic impurity removal method for an electromagnetic flowmeter, using the magnetic impurity removal device for an electromagnetic flowmeter as described above, comprises the following steps: S1. Before the flow rate of the conductive liquid is detected, the conductive liquid first enters the adsorption pipe 12. During this process, the magnetic attraction member 28 is activated to adsorb the magnetic impurities passing through the adsorption disk 24, so that the magnetic impurities are adsorbed on a certain surface of the adsorption disk 24.

[0055] S2. When the magnetic impurities on a certain part of the surface of the adsorption disk 24 accumulate to the maximum capacity, the stepper motor 23 starts, driving the adsorption disk 24 to rotate synchronously along the flow direction of the conductive liquid, so that the magnetic impurities on a certain part of the surface of the adsorption disk 24 are away from the magnetic suction member 28 and fall to the outside of the adsorption pipe 12 through rotation, while the surface of another part of the adsorption disk 24 will enter the adsorption pipe 12, and the magnetic impurities passing through the adsorption disk 24 will be adsorbed again, and this cycle is repeated.

[0056] S3. Subsequently, the adsorbed conductive liquid continues to be transported to the gathering pipe 13 and displaced along the distribution direction of the gathering pipe 13. At this time, since the flow rate of the conductive liquid slows down, it is not easy to carry the bubbles forward, and the bubbles float up due to gravity, so the bubbles will gather at the top of the inner wall of the middle end of the gathering pipe 13.

[0057] S4. During the working process of S3, the bubbles in the conductive liquid will enter the debubble box 31 and gradually fill the debubble box 31. With the entry of the bubbles, the liquid level of the conductive liquid in the debubble box 31 drops, and the floating plate 35 loses buoyancy and begins to drop. At the same time, the movable rod 34 and the sealing plate 33 are displaced synchronously, so that the spring 36 changes from a horizontal state to a bent state, and the sealing plate 33 no longer closes the debubble tube 32, thereby allowing the bubbles to be discharged through the debubble tube 32.

[0058] S5. As the bubbles are discharged, the conductive liquid will re-enter the debubble box 31, pushing the floating plate 35 to move upward, and pushing the movable rod 34 and the sealing plate 33 to rise synchronously, so that the sealing plate 33 and the debubble tube 32 are tightly fitted, and the debubble tube 32 is closed. At this time, the conductive liquid can only be in the debubble box 31 and will not leak. The spring 36 changes from a bent state to a horizontal state; this cycle is repeated.

[0059] S6. The conductive liquid continues to enter the transition pipe 14 and the detection pipe 15, and in the detection pipe 15, the flow rate is detected by the electromagnetic flowmeter 16, and then enters the next pipe through the delivery pipe 17.

[0060] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

10. A magnetic impurity removal method for an electromagnetic flowmeter, using the magnetic impurity removal device for an electromagnetic flowmeter as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Before the flow rate of the conductive liquid is detected, the conductive liquid first enters the adsorption pipe (12). During this process, the magnetic attraction member (28) is activated to adsorb the magnetic impurities passing through the adsorption plate (24), so that the magnetic impurities are adsorbed on a certain surface of the adsorption plate (24); S2. When the magnetic impurities on a certain part of the surface of the adsorption disk (24) accumulate to a maximum capacity, the stepper motor (23) is started to drive the adsorption disk (24) to rotate synchronously along the flow direction of the conductive liquid, so that the magnetic impurities on a certain part of the surface of the adsorption disk (24) are separated from the magnetic attraction member (28) and fall out of the adsorption pipe (12) through rotation, while the surface of another part of the adsorption disk (24) enters the adsorption pipe (12) and adsorbs the magnetic impurities passing through the adsorption disk (24) again, and the cycle is repeated; S3. Subsequently, the adsorbed conductive liquid continues to be transported into the gathering pipe (13) and moves along the distribution direction of the gathering pipe (13). At this time, since the flow rate of the conductive liquid slows down, it is not easy to carry the bubbles forward, and the bubbles float upward due to gravity, so the bubbles gather at the top of the inner wall of the middle end of the gathering pipe (13); S4. During the working process of S3, bubbles in the conductive liquid enter the debubble box (31) and gradually fill the debubble box (31). As the bubbles enter, the liquid level of the conductive liquid in the debubble box (31) decreases, and the floating plate (35) loses buoyancy and begins to descend. At the same time, the movable rod (34) and the sealing plate (33) are displaced synchronously, so that the spring (36) changes from a horizontal state to a bent state, and the sealing plate (33) no longer closes the debubble tube (32), thereby allowing the bubbles to be discharged through the debubble tube (32); S5. As the bubbles are discharged, the conductive liquid re-enters the debubble box (31), pushing the floating plate (35) to move upward, and pushing the movable rod (34) and the sealing plate (33) to rise synchronously, so that the sealing plate (33) and the debubble tube (32) are tightly fitted, and the debubble tube (32) is closed. At this time, the conductive liquid can only be in the debubble box (31) and will not leak. The spring (36) changes from a bent state to a horizontal state. This cycle is repeated. S6. The conductive liquid continues to flow into the transition pipe (14) and the detection pipe (15). The flow rate is detected by the electromagnetic flow meter (16) in the detection pipe (15), and then the conductive liquid enters the next pipe through the delivery pipe (17).
