High-precision intelligent measuring device for rituximab based on dynamic compensation

Abstract

This invention discloses a high-precision intelligent ritomotor flow meter based on dynamic compensation for use in flow measurement devices. This solution periodically sets a dynamic compensation detection phase to monitor the working status of the probe unit. When a risk of blockage is detected, the probe unit is broken sequentially from bottom to top until it can normally detect changes in flow. Simultaneously, the introduction of an interference device allows for dynamic monitoring of the probe unit's working status. This interference device does not require adjusting the fluid flow rate within the fluid pipeline, thus minimizing disruption to normal operation. Furthermore, the interference device can be moved to the vicinity of the positive and negative pressure taps of the probe unit, increasing detection accuracy. For fluids containing small amounts of impurities, long-term accurate detection is possible, reducing the likelihood of pressure tap blockage affecting the ritomotor flow meter's accuracy and causing it to fail.

Description

Technical Field

[0001] This invention relates to flow measurement devices, and more particularly to a high-precision intelligent litoba measurement device based on dynamic compensation. Background Technology

[0002] The Barrel-type flow meter is a double-layered hollow composite tube with a pair of pressure taps. It can simultaneously measure the total pressure and static pressure of a fluid. It needs to be used in conjunction with a differential pressure transmitter and a flow display instrument. It is widely used in industries such as petrochemicals, metallurgy, power plants, electric power, and textiles for flow measurement of fluids such as gases, liquids, steam, and water. The Barrel-type flow meter is an ideal replacement for orifice plates due to its advantages such as easy installation, low pressure loss, high strength, immunity to wear, and no leakage.

[0003] Utility model patent CN219736457U discloses a ligtoba sensor for measuring flow rate by inserting it into the center of a pipe. This sensor uses a probe placed inside the pipe with its lower end positioned at the center, reducing the length of the flow sensor and the amount of material used. It also improves the flow rate scale value and prevents the flow meter from bending due to excessive flow velocity. Utility model patent CN219757412U discloses a pipe-section type ligtoba flow meter. This pipe-section design allows for a fixed insertion depth and installation angle, ensuring the test data is identical to that in the laboratory, reducing measurement errors, and facilitating flow meter testing without requiring additional tooling.

[0004] Existing ritobalers are mainly used for fluid detection. By detecting the total pressure and static pressure of the fluid and combining it with Bernoulli's formula, the flow velocity of the fluid can be calculated. However, in actual use, the fluids such as gas, liquid, steam and water that are being detected are prone to impurities. When these impurities move with the fluid being detected, they can easily enter the pressure tap of the ritobaler, affecting the detection accuracy of the ritobaler and even causing the ritobaler to fail. Summary of the Invention

[0005] The core of this invention lies in the fact that by periodically setting a dynamic compensation detection stage, the working status of the probe unit can be detected, which can achieve accurate detection over a long period of time. It is less likely to affect the detection accuracy of the ritomoba flow meter due to the blockage of the pressure tap, and it is less likely to cause the ritomoba flow meter to fail.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] The lytoba high-precision intelligent measurement device based on dynamic compensation includes a detection tube inserted into a fluid pipeline. The two ends of the detection tube are located on the inner and outer sides of the fluid pipeline, respectively. A connecting unit is fixedly connected to the outer end of the detection tube. Multiple probe units are provided on the side of the detection tube away from the connecting unit. The multiple probe units are coaxial with the detection tube. The lower end of the detection tube is pointed. The upper end of each of the multiple probe units is provided with a conical groove that matches the lower end of the detection tube. The lower ends of the multiple probe units are pointed with the same size and shape as the lower end of the detection tube. Connecting rings are fixedly connected to the probe units adjacent to the detection tube and to the multiple adjacent probe units.

[0008] The probe unit includes a probe body with multiple storage grooves carved into its upper wall. Electromagnets are fixedly connected to the bottom plates of each storage groove. Impact piles are slidably connected inside the storage grooves, and compression springs are fixedly connected between the impact piles and the electromagnets. When the detection tube and the probe unit, as well as the two probe units, are installed, the upper end of the electromagnet contacts the inner wall of the connecting ring, and the lower end of the impact pile extends into the storage groove. By periodically setting dynamic compensation detection stages, the working status of the probe unit is detected, which can achieve accurate detection over a long period of time. It is not easy for the detection accuracy of the ritomoba flow meter to be affected by the blockage of the pressure tapping hole, and it is not easy for the ritomoba flow meter to fail.

[0009] Furthermore, the connecting ring includes a ring body, the inner wall of which is chiseled with a precast groove, and the precast groove is annular, providing a stress concentration point for the connecting ring, making it prone to breakage under the impact of the impact pile.

[0010] Furthermore, the upper inner wall of the precast trough gradually rises from the axial direction of the ring body outwards, which can control the shape of the fracture surface of the ring body, so that the part remaining on the upper probe unit after the ring body breaks is frustoconical, reducing its impact on fluid flow.

[0011] Furthermore, sealing ring one and sealing ring two are fixedly connected to the upper and lower ends of the ring body, respectively, and sealing ring two and sealing ring one are fixedly connected to the probe units at the upper and lower ends, respectively, thereby increasing the sealing between two adjacent probe units and between the detection tube and the probe unit.

[0012] Meanwhile, an interference device is fixedly connected to the fluid pipeline, and the fluid flow direction inside the fluid pipeline is from the interference device to the connecting unit. The interference device includes an electric telescopic rod inserted into the fluid pipeline. The upper and lower ends of the electric telescopic rod are located on the inner and outer sides of the fluid pipeline, respectively. A fixed base is fixedly connected to the upper end of the electric telescopic rod, and the fixed base is fixedly connected to the outer wall of the fluid pipeline. The electric telescopic rod includes a telescopic rod body. A rotating groove is chiseled at the end of the telescopic rod body away from the fixed base. A turbulence unit is provided on the lower side of the electric telescopic rod. The turbulence unit includes a rotating column rotatably connected to the rotating groove. A connecting column is fixedly connected to the lower end of the rotating column. A limit ring is fixedly connected to the opening of the rotating groove, and the limit ring is sleeved on the outside of the connecting column. A turbulence plate is fixedly connected to the lower end of the connecting column. The turbulence plate is used to turbulent the flow to determine whether there is blockage in the positive and negative pressure taps of the probe unit.

[0013] Furthermore, the asymmetrical structure of the baffle makes it difficult for the baffle to stabilize under the scouring of the fluid. Even when the baffle unit extends to the position of the lowest probe unit, it can still easily maintain rotation and facilitate subsequent testing.

[0014] Furthermore, the portion of the telescopic rod body located inside the fluid pipe is fitted with a streamlined armor. The streamlined armor is streamlined in shape, and the turbulence-disrupting unit is completely contained within the streamlined armor when it is not in operation, thereby reducing the impact of the turbulence-disrupting unit on the normal operation of the probe unit.

[0015] Furthermore, multiple elastic fibers are fixedly connected to the inner wall of the streamlined armor opening. These elastic fibers are all three-dimensional spirals and overlap each other. Without affecting the normal movement of the turbulence unit, the elastic fibers can effectively reduce the probability of turbulence forming at the streamlined armor opening and reduce the impact on the probe unit detection.

[0016] Compared with the prior art, the advantages of this invention are:

[0017] This solution uses a periodic dynamic compensation detection phase to monitor the working status of the probe unit. When a risk of blockage is detected, the probe unit is broken sequentially from bottom to top until it can detect flow changes normally. For fluids containing a small amount of impurities, it can achieve accurate detection over a long period of time and is less likely to affect the detection accuracy of the Libero flow meter due to blockage of the pressure tap, thus reducing the risk of Libero flow meter failure.

[0018] The introduction of the interference device allows for dynamic detection of the probe unit's operating status. The interference device does not require adjustment of the fluid flow rate in the fluid pipeline, making it less likely to affect the normal operation of the fluid pipeline. Furthermore, the turbulence unit can be moved to the vicinity of the positive and negative pressure taps of the probe unit, resulting in higher detection accuracy. Attached Figure Description

[0032] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0033] First implementation method:

[0034] Please see Figures 1-3 and Figures 5-8 The lytoba high-precision intelligent measuring device based on dynamic compensation includes a detection tube 3 inserted into a fluid pipeline 1. The two ends of the detection tube 3 are located on the inner and outer sides of the fluid pipeline 1, respectively. A connection unit 2 is fixedly connected to the outer end of the detection tube 3. The connection unit 2 is connected to a differential pressure transmitter, a flow display, and a controllable valve body for flow detection and display of the detection results. Simultaneously, the flow display is equipped with a control terminal, which can process the detection data from the differential pressure transmitter and other electrical equipment according to a preset program, and control the operating status of the electrical equipment. The detection tube 3 is located away from the connection unit 2. Multiple probe units 4 are provided on one side of unit 2. Both the detection tube 3 and the probe units 4 are drilled with matching positive pressure taps and negative pressure taps. The fluid in the fluid pipe 1 flows from the positive pressure tap to the negative pressure tap. The multiple probe units 4 are coaxial with the detection tube 3. The lower end of the detection tube 3 is pointed. The upper end of the multiple probe units 4 is provided with a conical groove that matches the lower end of the detection tube 3. The lower end of the multiple probe units 4 is a pointed head with the same size and shape as the lower end of the detection tube 3. Connecting rings 5 ​​are fixedly connected between the probe units 4 adjacent to the detection tube 3 and between multiple adjacent probe units 4.

[0035] The probe unit 4 includes a probe body 401. Multiple energy storage grooves 402 are carved on the upper wall of the probe body 401. Electromagnets 403 are fixedly connected to the bottom plates of the multiple energy storage grooves 402. Impact piles 404 are slidably connected inside the energy storage grooves 402. Compression springs 405 are fixedly connected between the impact piles 404 and the electromagnets 403. When the detection tube 3, the probe unit 4, and the two probe units 4 are installed, the upper end of the electromagnet 403 contacts the inner wall of the connecting ring 5, and the lower end of the impact pile 404 extends into the energy storage groove 402.

[0036] When multiple probe units 4 are used to detect the flow rate of the fluid in the fluid pipe 1, the fluid flow direction is from the positive pressure tap to the negative pressure tap. At this time, the pressure measured by the positive pressure tap is the total pressure of the fluid, while the pressure measured by the negative pressure tap is the static pressure of the fluid. According to Bernoulli's equation, the fluid velocity is calculated by the difference between the total pressure and the static pressure of the fluid, the flow coefficient of the probe unit 4 (which is determined by the structural shape of the probe unit 4 and can be calibrated by experiment at the factory), and the fluid density. When there is a large difference in the fluid temperature in the fluid pipe 1, a temperature sensor needs to be installed in the fluid pipe 1 or on the detection tube 3 to calculate the density change of the fluid caused by the temperature change.

[0037] During flow detection, a dynamic compensation detection phase is set periodically. In this phase, the flow velocity in fluid pipeline 1 is randomly and rapidly adjusted (this can be controlled via valves or other simple obstructions). If the detection results from the positive and negative pressure taps of probe unit 4 change rapidly with the adjustment, it indicates that probe unit 4 is not blocked and the litoba flowmeter is operating normally. However, if the detection data from the positive and negative pressure taps of probe unit 4 show more than one slow response, it indicates that the detection progress of probe unit 4 is affected and dynamic adjustment is required. At this time, the electromagnet 403 inside probe unit 4 located directly below is energized. Upon activation, the impact pile 404 is attracted to itself, storing energy for the compression spring 405. Then, the electromagnet 403 is de-energized, and the impact pile 404, under the action of the compression spring 405 in a compressed state, impacts the connecting ring 5, causing the connecting ring 5 to break. The bottom probe unit 4 falls off, and the top probe unit 4 is activated to continue the dynamic compensation detection phase. When the detection data of the positive and negative pressure taps of the probe unit 4 still show more than one slow response, the bottom probe unit 4 is separated again until the detection results of the positive and negative pressure taps of the probe unit 4 show that the flow rate changes rapidly according to the control.

[0038] The probe body 401 is equipped with a battery that provides power to the electromagnet 403. The working state of the electromagnet 403 is controlled by the control terminal. After the electromagnet 403 is started, it needs to perform three start-stop cycles so that the impact pile 404 can impact the connecting ring 5 three times, making the connecting ring 5 more likely to break. Those skilled in the art can make reasonable designs based on the existing technology to meet the usage requirements of this application.

[0039] The connecting ring 5 includes a ring body 501. The inner wall of the ring body 501 is chiseled with a precast groove 504. The precast groove 504 is annular, which provides a stress concentration point for the connecting ring 5. It is easy to break under the impact of the impact pile 404. The annular precast groove 504 is better resistant to the scouring of fluid and is not easy to break prematurely under the scouring of fluid.

[0040] The upper inner wall of the precast groove 504 gradually rises outward from the axial direction of the ring 501, which can control the shape of the fracture surface of the ring 501. This makes the part of the ring 501 remaining on the upper probe unit 4 after the ring 501 breaks into a frustum shape, reducing its influence on fluid flow and reducing its influence on the detection of positive and negative pressure taps.

[0041] The upper and lower ends of the ring body 501 are respectively fixedly connected with sealing ring 1 502 and sealing ring 2 503, and sealing ring 2 503 and sealing ring 1 502 are respectively fixedly connected with the probe units 4 at the upper and lower ends, which increases the sealing between the two adjacent probe units 4 and the detection tube 3 and the probe unit 4, and is less likely to affect the detection results of the positive pressure tapping hole and the negative pressure tapping hole.

[0042] Both the probe unit 4 and the connecting ring 5 are made of lightweight materials, and their densities are less than the density of the fluid to be tested. This allows the detached probe unit 4 and connecting ring 5 to quickly leave the location of the detection tube 3 under the flushing of the fluid, making it less likely for the detached probe unit 4 and connecting ring 5 to accumulate near the location of the detection tube 3. The accumulation of probe unit 4 and connecting ring 5 is less likely to cause turbulence and affect the detection results of the positive and negative pressure taps.

[0043] In this implementation method, the working status of probe unit 4 is detected by setting a dynamic compensation detection stage at regular intervals. When the risk of blockage of probe unit 4 is found, probe unit 4 is broken sequentially from bottom to top until probe unit 4 can detect the change in flow rate normally. For fluids containing a small amount of impurities, accurate detection can be achieved for a long time. The detection accuracy of the Libero flow meter is not easily affected by the blockage of the pressure tap, and the Libero flow meter is not easily caused to fail.

[0044] Second implementation method:

[0045] Please see Figure 2 , Figure 4 and Figures 10-11 An interference device is fixedly connected to the fluid pipeline 1, and the fluid flow direction in the fluid pipeline 1 is from the interference device to the connection unit 2. The interference device includes an electric telescopic rod 7 inserted into the fluid pipeline 1. The upper and lower ends of the electric telescopic rod 7 are located on the inner and outer sides of the fluid pipeline 1, respectively. A fixed base 6 is fixedly connected to the upper end of the electric telescopic rod 7, and the fixed base 6 is fixedly connected to the outer wall of the fluid pipeline 1. The electric telescopic rod 7 includes a telescopic rod body 701. A rotating groove is carved at the end of the telescopic rod body 701 away from the fixed base 6. A flow disturbance unit 8 is provided on the lower side of the electric telescopic rod 7. The flow disturbance unit 8 includes a rotating groove. A rotating column 802 is movably connected to the rotating groove. A connecting column 803 is fixedly connected to the lower end of the rotating column 802. A limiting ring 702 is fixedly connected to the opening of the rotating groove, and the limiting ring 702 is sleeved on the outside of the connecting column 803. A baffle 801 is fixedly connected to the lower end of the connecting column 803. When dynamic compensation detection of the probe unit 4 is required, the telescopic rod body 701 can be adjusted so that the baffle 801 moves to the positive pressure tap and negative pressure tap of the lowest probe unit 4. The baffle 801 is used to turbulence the air to determine whether there is blockage in the positive pressure tap and negative pressure tap of the probe unit 4.

[0046] The spoiler 801 has an asymmetrical structure, which makes it difficult for the spoiler 801 to be stable under the scouring of the fluid. Even when the spoiler unit 8 extends to the position of the lowest probe unit 4, it can still easily maintain rotation and be used in subsequent detection work.

[0047] The telescopic rod body 701 is fitted with a streamlined armor 9 on the inner side of the fluid pipe 1. The streamlined armor 9 is streamlined, and the turbulence-disrupting unit 8 is completely contained within the streamlined armor 9 when it is not in operation, thus reducing the impact of the turbulence-disrupting unit 8 on the normal operation of the probe unit 4. Multiple elastic fibers 10 are fixedly connected to the inner wall of the opening of the streamlined armor 9. The multiple elastic fibers 10 are all three-dimensional spirals and overlap each other. The elastic fibers 10 can also effectively reduce the probability of turbulence forming at the opening of the streamlined armor 9 without affecting the normal movement of the turbulence-disrupting unit 8, thereby reducing the impact on the detection of the probe unit 4.

[0048] Compared to the first embodiment, the introduction of the interference device in this embodiment allows for dynamic detection of the working status of the probe unit 4. Compared to the first embodiment, which directly controls the flow rate using valves or other structures, the interference device does not need to regulate the fluid flow rate in the fluid pipeline 1, and is less likely to affect the normal operation of the fluid pipeline 1. Furthermore, the turbulence unit 8 can be moved to the vicinity of the positive and negative pressure taps of the probe unit 4, resulting in higher detection accuracy. However, it requires the creation of corresponding mounting holes on the fluid pipeline 1 for installation, which increases the cost of use to some extent. Those skilled in the art can make a reasonable choice between the two embodiments based on actual usage requirements.

[0049] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
