Description

Technical Field

[0001] This utility model relates to the field of electromagnetic flowmeter technology, and in particular to an anti-clogging electromagnetic flowmeter. Background Technology

[0002] Electromagnetic flowmeters are instruments that measure the flow rate of a conductive fluid by utilizing the principle of electromagnetic induction and the electromotive force generated when the fluid passes through an external magnetic field. The main components of an electromagnetic flowmeter include a magnetic circuit system, a measuring conduit, electrodes, a housing, a lining, and a converter. The magnetic circuit system generates a uniform DC or AC magnetic field, and electromagnetic flowmeters play a crucial role in flow monitoring. However, during prolonged use, impurities inside the electromagnetic flowmeter can clog the measuring pipe, affecting measurement accuracy and hindering pipeline inspection. Therefore, there is an urgent need for an anti-clogging electromagnetic flowmeter.

[0003] Currently, the anti-clogging design of electromagnetic flowmeters involves installing a filter screen at the inlet end to block impurities. However, this filter screen design requires operators to assess the amount of impurities on the screen and periodically remove it to clean the impurities. This repeated disassembly and cleaning process is cumbersome and places high demands on the overall sealing of the electromagnetic flowmeter. Utility Model Content

[0004] The technical problem this invention aims to solve is: to address the issue that the cumbersome cleaning process of the filter screen in existing anti-clogging electromagnetic flowmeters affects the overall detection efficiency of the electromagnetic flowmeter, this invention provides an anti-clogging electromagnetic flowmeter. By improving the structure of the anti-clogging electromagnetic flowmeter, it enables the cleaning of impurities without disassembling the filter screen, simplifying the cleaning steps and improving the cleaning efficiency of the filter screen.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an anti-clogging electromagnetic flowmeter, comprising: an electromagnetic flowmeter body, a measuring pipe, a first slag discharge section, a first filter section, and a first flushing section. The measuring pipe is connected to the electromagnetic flowmeter body and is used to flow the liquid to be measured. The flow rate of the liquid to be measured is detected and displayed by the electromagnetic flowmeter body. The first slag discharge section, the first filter section, and the first flushing section are all installed at one end of the measuring pipe and are distributed sequentially along the direction from the end of the measuring pipe to the center. The first filter section is used to block impurities in the liquid to be measured to achieve the anti-clogging operation of the measuring pipe. The first flushing section is used to spray liquid and act in the opposite direction on the first filter section to wash away the impurities attached to the first filter section and discharge it through the first slag discharge section to achieve the cleaning operation of the impurities attached to the first filter section.

[0006] Therefore, by setting up a first filter section to enable the entire electromagnetic flowmeter to have an anti-clogging function, and by setting up a first slag discharge section and a first flushing section to achieve the flushing operation of impurities, compared with the existing method of disassembling the filter screen to clean impurities, this method has a simple structure and is easy to operate. The first flushing section can backwash away the impurities attached to the first filter section and discharge them through the first slag discharge section, so as to achieve the cleaning operation of impurities without disassembling the first filter section, simplifying the cleaning steps of the first filter section and improving the cleaning efficiency of the first filter section. In addition, since the first filter section can achieve the cleaning operation without disassembling it, the first slag discharge section, the first filter section, the first flushing section and the measuring pipe are integrated into one unit, which can improve the sealing effect of the entire electromagnetic flowmeter, thereby improving the accuracy of the electromagnetic flowmeter detection results.

[0007] As a further improvement to the above technical solution: the first slag discharge section includes a first slag discharge pipe and a first solenoid valve. The first slag discharge pipe is connected to the measuring pipe, and the first solenoid valve is connected in series with the first solenoid valve. Therefore, during the cleaning of impurities on the first filter section, opening the first solenoid valve allows the washed-off impurities to be discharged through the first slag discharge pipe.

[0008] As a further improvement to the above technical solution: the first filtration section includes a filter tube and a first filter screen. The filter tube is embedded in the measuring pipe, and the first filter screen is installed on the filter tube and located on the side of the filter tube closer to the center of the measuring pipe. Thus, the first filter screen can block impurities, ensuring that impurities do not enter the center of the measuring pipe, thereby achieving the anti-clogging function of the entire electromagnetic flowmeter.

[0009] As a further improvement to the above technical solution: the cross-sectional width of the filter tube gradually decreases along the direction from the end of the measuring pipe to the center. Therefore, by using a filter tube with a gradually decreasing cross-sectional width, on the one hand, the resistance to impurity flow is increased, allowing impurities to remain on the side of the filter tube away from the first filter screen, thus reducing the risk of impurities adhering to the first filter screen; on the other hand, during rinsing, it facilitates the flow of impurities along the filter tube to the slag discharge pipe, making impurity cleaning easier.

[0010] As a further improvement to the above technical solution: the first rinsing section includes a rinsing pipe, a second filter screen, and a nozzle. The two ends of the rinsing pipe are located on opposite sides of the first filter section, and the end of the rinsing pipe closest to the end of the measuring pipe is connected to the pipe to be tested. The second filter screen is installed on the pipe to be tested. The end of the rinsing pipe furthest from the end of the measuring pipe is inserted into the measuring pipe. The nozzle is installed on the end of the rinsing pipe furthest from the end of the measuring pipe, and the outlet end of the nozzle is aligned with the first filter section. Therefore, during the cleaning of impurities on the first filter section, the second solenoid valve is opened, allowing fluid from the pipe to be tested to pass through the rinsing pipe and nozzle, and act on the first filter screen through the nozzle. This allows for rinsing using the fluid from the pipe to be tested, thus removing impurities attached to the first filter screen. Simultaneously, the second filter screen intercepts impurities, preventing them from flowing into the center of the measuring pipe through the rinsing pipe and nozzle during the cleaning of impurities on the first filter section, thus simultaneously preventing blockage during the impurity cleaning process.

[0011] As a further improvement to the above technical solution: a second solenoid valve is connected in series on the flushing pipe, and the second solenoid valve is located outside the measuring pipe. Thus, opening the second solenoid valve allows the flushing pipe to be in a conductive state, thereby cleaning the impurities adhering to the first filter screen.

[0012] As a further improvement to the above technical solution, it also includes a second slag discharge section, a second filter section, and a second flushing section. These three sections are all installed at the other end of the measuring pipe and are distributed sequentially along the direction from the end of the measuring pipe to its center. Thus, with slag discharge, filter, and flushing sections installed on both sides of the measuring pipe, it provides anti-clogging and impurity removal functions on both sides. This design eliminates the need to consider the installation direction when installing the electromagnetic flowmeter, facilitating its installation. Furthermore, regardless of which side of the measuring pipe is connected to the pipe being measured, no impurities will flow into the center of the measuring pipe, ensuring the entire measuring pipe remains in an anti-clogging state.

[0013] As a further improvement to the above technical solution: the second slag discharge section has the same structure as the first slag discharge section, the second filter section has the same structure as the first filter section, and the second rinsing section has the same structure as the first rinsing section.

[0014] As a further improvement to the above technical solution: a first flange is provided at one end of the measuring pipe.

[0015] As a further improvement to the above technical solution, a second flange is provided at the other end of the measuring pipe. Thus, convenient installation between the measuring pipe and the pipe fitting to be measured can be achieved through the first flange and the second flange.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides an anti-clogging function to the entire electromagnetic flowmeter by setting a first filter section, and washes away impurities by setting a first slag discharge section and a first flushing section. Compared with the existing method of disassembling the filter screen to clean impurities, this method has a simple structure and is easy to operate. The first flushing section can wash away the impurities attached to the first filter section and discharge them through the first slag discharge section, so as to achieve the cleaning of impurities without disassembling the first filter section, simplifying the cleaning steps of the first filter section and improving the cleaning efficiency of the first filter section. In addition, since the first filter section can be cleaned without disassembly, the first slag discharge section, the first filter section, the first flushing section and the measuring pipe are integrated into one unit, which can improve the sealing effect of the entire electromagnetic flowmeter and thus improve the accuracy of the electromagnetic flowmeter detection results.

[0017] 2. In the process of cleaning impurities on the first filter section, the first solenoid valve is opened, and the washed-off impurities can be discharged through the first slag discharge pipe.

[0018] 3. This utility model uses a first filter screen to block impurities, ensuring that they do not enter the center of the measuring pipe, thus achieving the anti-clogging function of the entire electromagnetic flowmeter. The filter tube with a gradually decreasing cross-sectional width increases the resistance to impurity flow, causing impurities to remain on the side of the filter tube away from the first filter screen, reducing the risk of impurities adhering to the first filter screen. Furthermore, during rinsing, it facilitates the flow of impurities along the filter tube to the slag discharge pipe, making cleaning easier.

[0019] 4. In the process of cleaning impurities on the first filter section, the second solenoid valve is opened to allow fluid in the test tube to pass through the flushing pipe and nozzle, and act on the first filter screen through the nozzle. This allows the fluid in the test tube to perform flushing operations to remove impurities attached to the first filter screen. At the same time, the second filter screen can intercept impurities to prevent them from flowing into the center of the measuring pipe through the flushing pipe and nozzle during the cleaning of impurities on the first filter section, thus achieving anti-clogging during the impurity cleaning process. Opening the second solenoid valve allows the flushing pipe to be in a conductive state, and the flushing pipe in a conductive state is used to clean the impurities attached to the first filter screen.

[0020] 5. This utility model has a slag discharge section, a filter section, and a flushing section installed on both sides of the measuring pipe, which can provide anti-clogging and impurity cleaning functions on both sides of the measuring pipe. With this design, on the one hand, there is no need to consider the installation direction when installing the electromagnetic flow meter, so as to facilitate the installation of the entire electromagnetic flow meter. On the other hand, no matter which side of the measuring pipe is connected to the pipe to be measured, no impurities will flow in the center of the measuring pipe, and the entire measuring pipe is always in an anti-clogging state.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figures 1 to 5The diagram shows the preferred embodiment of this utility model. The anti-clogging electromagnetic flowmeter of this embodiment includes: an electromagnetic flowmeter body 1, a measuring pipe 2, a first slag discharge section 3, a first filter section 4, and a first flushing section 5. The measuring pipe 2 is connected to the electromagnetic flowmeter body 1 and is used to flow the liquid to be measured. The flow rate of the liquid to be measured is detected and displayed by the electromagnetic flowmeter body 1. The first slag discharge section 3, the first filter section 4, and the first flushing section 5 are all installed at one end of the measuring pipe 2 and are distributed sequentially along the direction from the end of the measuring pipe 2 to the center. The first filter section 4 is used to block impurities in the liquid to be measured to achieve the anti-clogging operation of the measuring pipe 2. The first flushing section 5 is used to spray liquid and act in the opposite direction on the first filter section 4 to wash away the impurities attached to the first filter section 4 and discharge it through the first slag discharge section 3 to achieve the cleaning operation of the impurities attached to the first filter section 4. Therefore, by setting the first filter section 4, the entire electromagnetic flowmeter has an anti-clogging function. By setting the first slag discharge section 3 and the first flushing section 5, the impurities are flushed. Compared with the existing method of disassembling the filter screen to clean impurities, this method has a simple structure and is easy to operate. The first flushing section 5 can backwash the impurities attached to the first filter section 4 and discharge them through the first slag discharge section 3, so as to achieve the cleaning of impurities without disassembling the first filter section 4, simplifying the cleaning steps of the first filter section 4 and improving the cleaning efficiency of the first filter section 4. In addition, since the first filter section 4 can be cleaned without disassembly, the first slag discharge section 3, the first filter section 4, the first flushing section 5 and the measuring pipe 2 are integrated into one unit. This can improve the sealing effect of the entire electromagnetic flowmeter, thereby improving the accuracy of the electromagnetic flowmeter's detection results.

[0028] In this embodiment, the first slag discharge section 3 includes a first slag discharge pipe 301 and a first solenoid valve 302. The first slag discharge pipe 301 is connected to the measuring pipe 2, and the first solenoid valve 302 is connected in series. Thus, during the cleaning of impurities on the first filter section 4, the first solenoid valve 302 is opened, and the washed-off impurities can be discharged through the first slag discharge pipe 301.

[0029] In this embodiment, the first filter section 4 includes a filter tube 401 and a first filter screen 402. The filter tube 401 is embedded in the measuring pipe 2, and the first filter screen 402 is installed on the filter tube 401 and located on the side of the filter tube 401 near the center of the measuring pipe 2. The cross-sectional width of the filter tube 401 gradually decreases along the direction from the end of the measuring pipe 2 to the center. Thus, the first filter screen 402 can block impurities, ensuring that impurities do not enter the center of the measuring pipe 2, thereby achieving the anti-clogging function of the entire electromagnetic flowmeter. The gradually decreasing cross-sectional width of the filter tube 401 increases the resistance to impurity flow, allowing impurities to remain on the side of the filter tube 401 away from the first filter screen 402, thus reducing the risk of impurities adhering to the first filter screen 402. Furthermore, during rinsing, it facilitates the flow of impurities along the filter tube 401 to the slag discharge pipe, making impurity cleaning easier.

[0030] In this embodiment, the first rinsing section 5 includes a rinsing pipe 501, a second filter screen 502, and a nozzle 503. The two ends of the rinsing pipe 501 are located on both sides of the first filter section 4, and the end of the rinsing pipe 501 near the end of the measuring pipe 2 is connected to the pipe to be tested. The second filter screen 502 is installed on the pipe to be tested. The end of the rinsing pipe 501 away from the end of the measuring pipe 2 is inserted into the measuring pipe 2. The nozzle 503 is installed at the end of the rinsing pipe 501 away from the end of the measuring pipe 2, and the outlet end of the nozzle 503 is aligned with the first filter section 4. A second solenoid valve 504 is connected in series on the rinsing pipe 501, and the second solenoid valve 504 is located outside the measuring pipe 2. Therefore, during the cleaning of impurities on the first filter section 4, the second solenoid valve 504 is opened, allowing the fluid in the test tube to pass through the flushing pipe 501 and the nozzle 503, and acting on the first filter screen 402 through the nozzle 503. This allows the fluid in the test tube to perform flushing operations, thereby cleaning the impurities attached to the first filter screen 402. At the same time, the second filter screen 502 can intercept impurities to prevent them from flowing into the center of the measuring pipe 2 through the flushing pipe 501 and the nozzle 503 during the cleaning of impurities on the first filter section 4, thus achieving anti-clogging during the cleaning process. The second solenoid valve 504 is opened, so that the flushing pipe 501 is in a conductive state, and the cleaning of impurities attached to the first filter screen 402 is achieved through the conductive state of the flushing pipe 501.

[0031] It should be noted that a valve (not shown in the figure) is installed between the pipe fitting to be tested (not shown in the figure) and the first flange 9 or the second flange 10. The end of the flushing pipe 501 near the end of the measuring pipe 2 is installed on the pipe fitting to be tested and is located at the end of the valve away from the measuring pipe 2. When the electromagnetic flowmeter performs the detection function, the valve is open, the first solenoid valve 302 and the second solenoid valve 504 are closed, and the pipe fitting to be tested and the measuring pipe 2 are directly connected. The flushing pipe 501 is in a closed state, and the liquid flows directly through the pipe fitting to be tested to the measuring pipe 2. When the electromagnetic flowmeter performs the impurity cleaning operation, the valve is closed, the first solenoid valve 302 and the second solenoid valve 504 are open, and the pipe fitting to be tested and the measuring pipe 2 are indirectly connected. The flushing pipe 501 is in a connected state, and the liquid flows through the pipe fitting to be tested to the flushing pipe 501 and then through the nozzle 503 to flush the first filter screen 402 to clean the impurities attached to the first filter screen 402. The cleaned impurities are discharged through the slag discharge pipe.

[0032] In this embodiment, the system further includes a second slag discharge section 6, a second filter section 7, and a second flushing section 8. These sections are all installed at the other end of the measuring pipe 2 and are distributed sequentially along the direction from the end of the measuring pipe 2 to its center. The second slag discharge section 6 has the same structure as the first slag discharge section 3, the second filter section 7 has the same structure as the first filter section 4, and the second flushing section 8 has the same structure as the first flushing section 5. Thus, with slag discharge, filter, and flushing sections installed on both sides of the measuring pipe 2, both sides of the measuring pipe 2 can have anti-clogging and impurity cleaning functions. This design, on the one hand, eliminates the need to consider the installation direction when installing the electromagnetic flowmeter, facilitating the installation of the entire electromagnetic flowmeter; on the other hand, regardless of which side of the measuring pipe 2 is connected to the pipe to be measured, no impurities will flow into the center of the measuring pipe 2, and the entire measuring pipe 2 is always in an anti-clogging state.

[0033] In this embodiment, a first flange 9 is provided at one end of the measuring pipe 2, and a second flange 10 is provided at the other end of the measuring pipe 2. Thus, convenient installation between the measuring pipe 2 and the pipe fitting to be tested can be achieved through the first flange 9 and the second flange 10.

[0034] The working process of this electromagnetic flowmeter is as follows: First, the measuring pipe 2 is connected to the pipe to be tested through the first flange 9 and the second flange 10. Next, when the electromagnetic flowmeter performs the detection function, the valve is opened and the first solenoid valve 302 and the second solenoid valve 504 are closed, so that the pipe to be tested and the measuring pipe 2 are directly connected. The flushing pipe 501 is in a closed state, and the liquid flows directly through the pipe to be tested to the measuring pipe 2. The detection data is read through the electromagnetic flowmeter body 1. Finally, when the electromagnetic flowmeter performs the impurity cleaning operation, the valve is closed and the first solenoid valve 302 and the second solenoid valve 504 are opened, so that the pipe to be tested and the measuring pipe 2 are indirectly connected. The flushing pipe 501 is in a connected state, and the liquid flows through the pipe to be tested to the flushing pipe 501. The liquid then passes through the nozzle 503 to flush the first filter screen 402, thereby cleaning the impurities attached to the first filter screen 402. The cleaned impurities are discharged through the slag discharge pipe.

[0035] In summary, this utility model provides an anti-clogging function to the entire electromagnetic flowmeter by setting a first filter section 4, and washes away impurities by setting a first slag discharge section 3 and a first flushing section 5. Compared with the existing method of disassembling the filter screen to clean impurities, this method has a simple structure and is easy to operate. The first flushing section 5 can wash away the impurities attached to the first filter section 4 in the reverse direction and discharge them through the first slag discharge section 3, so as to achieve the cleaning of impurities without disassembling the first filter section 4, simplifying the cleaning steps of the first filter section 4 and improving the cleaning efficiency of the first filter section 4. In addition, since the first filter section 4 can be cleaned without disassembly, the first slag discharge section 3, the first filter section 4, the first flushing section 5 and the measuring pipe 2 are integrated into one unit, which can improve the sealing effect of the entire electromagnetic flowmeter and thus improve the accuracy of the electromagnetic flowmeter detection results.

[0036] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
