Description

Technical Field

[0001] The present application belongs to the technical field of flowmeters, and specifically relates to an anti-clogging electromagnetic flowmeter. Background Art

[0002] Electromagnetic flowmeter is a device that measures the flow rate of liquid by detecting the electromagnetic force lines in the liquid when the conductive liquid flows through the pipe. It is suitable for flow measurement in industries such as water, sewage, food and beverage, and chemical industry, and is currently a widely used flowmeter in industrial flow measurement.

[0003] For example, an application with publication number CN220251094U discloses an anti-clogging electromagnetic flowmeter, which relates to the technical field of flowmeters and includes a shell and a display fixedly mounted on the outer wall of the shell, wherein an inner cavity is provided inside the shell, the middle part of the inner cavity is a fast flow channel, and the two sides of the inner cavity are slow flow channels, and an inclined variable flow channel is provided between the fast flow channel and the slow flow channel, and a clearing mechanism is also fixedly mounted inside the shell, wherein the clearing mechanism includes a fixed frame installed inside the shell, a fixed sleeve is fixedly mounted on the inner side of the fixed frame, the fixed sleeve is mounted on the outer side of a movable rod, a reset spring is detachably mounted on the outer wall of the movable rod, and a clearing ring is fixedly connected to one end of the movable rod. This anti-clogging electromagnetic flowmeter is different from the prior art in that the electromagnetic flowmeter does not need to be disassembled for clearing, the operation is simple and convenient, and the clearing efficiency is high. Moreover, since the inner diameter of the fast flow channel is smaller than the inner diameter of the slow flow channel, the flow velocity of the fluid in the fast flow channel will increase, thereby reducing the probability of clogging by dirt.

[0004] However, this application places a large number of components in the center of the pipeline, which is not conducive to pipeline transmission efficiency and is more likely to block impurities and cause pipeline blockage. Utility Model Content

[0005] The purpose of the present application is to provide an anti-clogging electromagnetic flowmeter in order to solve the above-mentioned problem that a large number of components are placed in the center of the pipeline, which is not conducive to pipeline transmission efficiency and is more likely to block impurities and cause pipeline blockage.

[0006] The technical solution adopted in the present application is as follows: an anti-clogging electromagnetic flowmeter comprises a main pipe, a positioning flange is welded on the outer surface of one side of the main pipe, a fixing flange is movably connected to the outer surface of the positioning flange away from the end of the main pipe, bolts are arranged on the outer surface of the fixing flange, a dredging pipe is movably connected to the inner surface of the bolts, a push rod is welded on the outer surface of the dredging pipe, and a fixing groove is movably connected to the outer surface of the dredging pipe corresponding to the push rod.

[0007] By adopting the above technical solution, when in use, the main pipeline of the equipment provides the main function of the electromagnetic flowmeter, the positioning flange and the fixing flange are fixed by bolts, and the fixing groove is fixed at the support platform, providing a limit for the displacement of the dredging pipe, ensuring that the dredging pipe can only move forward and backward in the inner wall of the main pipeline corresponding to the main pipeline. The dredging pipe can be displaced forward and backward through the push rod, and the outer surface of the dredging pipe corresponding to the main pipeline adopts a knife-shaped cutting to separate the impurities from the inner surface of the main pipeline, so as to achieve the dredging effect without opening the pipeline. The operation can also be carried out during normal maintenance to ensure the cleanliness of the inside of the pipeline. This operation can be used for dredging when blocked. When the dredging pipe is still blocked after completing the displacement, it can be determined that there is a problem upstream of the valve or other pipelines, which reduces downtime, reduces production losses, and provides convenience. When the dredging pipe cannot complete the overall displacement, the bolts are opened to remove the fixing flange, and the displaced outer surface of the dredging pipe is separated from the main pipeline. The pipeline can be quickly disassembled during external activities to carry out related dredging operations.

[0008] In a preferred embodiment, a support platform is welded to the outer surface of the fixed groove, the support platform and the corresponding outer surface of the main pipeline are welded to each other, a label is movably connected to the lower end of the outer surface of the support platform, and a connecting pipe is welded to the outer surface of the support platform corresponding to the dredging pipe.

[0009] By adopting the above technical solution, the support platform supports the fixed groove to ensure the displacement of the dredging pipe, the label is convenient for maintenance personnel to query the relevant parameters of the flow meter, and the connecting pipe is used to limit the dredging pipe to ensure the stability of the entire pipeline.

[0010] In a preferred embodiment, a metal strip is fixedly connected to the outer surface of the desilting pipe, and a grounding wire is fixedly connected to the outer surface of the support platform.

[0011] By adopting the above technical solution, the impurity blockage in the electromagnetic flowmeter is largely due to the magnetic adsorption of the impurities in the pipeline. As time goes by, more and more impurities are produced, and the dredging pipe is displaced into the inner surface of the main pipeline. The metal strips and grounding wires are grounded to demagnetize the impurities, increasing the probability of impurity removal.

[0012] In a preferred embodiment, an outer buffer tube is welded to the outer surface of one side of the main pipeline away from the positioning flange, and a support plate is fixedly connected to the outer surface of one end of the outer buffer tube away from the main pipeline.

[0013] By adopting the above technical solution, the external buffer tube and the support plate ensure that the pipeline can be connected to the main pipeline for buffering, which can buffer the damage of impurities to the main pipeline.

[0014] In a preferred embodiment, a screen is movably connected to the inner surface of the outer buffer tube, and a second connecting tube is movably connected to the upper surface of the support plate beside the screen.

[0015] By adopting the above technical solution, the screen blocks large particles of impurities and filters the impurities to avoid blockage inside the main pipeline, and the second connecting pipe ensures the sealing of the pipeline.

[0016] In a preferred embodiment, the outer surface of the second connecting pipe is movably connected to a limiting block, and the upper surface of the limiting block is welded with a pull-out block.

[0017] By adopting the above technical solution, when there is a blockage in the equipment pipeline, the limit block can be taken out by pulling out the block, and the second connecting pipe can be moved toward the inner surface of the tee pipe, so that impurities in front of the screen can be removed, and the screen can also be taken out for further dredging or replacement.

[0018] In a preferred embodiment, a tee is welded to the outer surface of one end of the support plate away from the outer buffer tube, and a sealing member is provided on the inner surface of the tee.

[0019] By adopting the above technical solution, the plugging piece is fixed by threads to block the hole above the tee pipe. When the equipment is blocked upstream, the impurities in the screen can be sucked out by a negative pressure pump, or the pipeline can be dredged and cleared after the screen is taken out.

[0020] In a preferred embodiment, a magnetic induction coil is fixedly connected to the inner surface of the main pipe, an electrode is fixedly connected to the inner surface of the main pipe, an electromagnetic analysis body is arranged on the upper surface of the main pipe, and a display screen is fixedly connected to the outer surface of the electromagnetic analysis body.

[0021] By adopting the above technical solution, the magnetic field generated by the magnetic induction coil generates voltage through the cutting of charged particles in the pipeline, the electrode receives the signal and transmits it to the electromagnetic analysis body, the internal circuit data of the electromagnetic analysis body is processed and analyzed, and the flow rate is displayed on the display screen, completing the main functions of the equipment.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In the present application, when in use, the main pipeline of the equipment provides the main function of the electromagnetic flowmeter, the positioning flange and the fixing flange are fixed by bolts, and the fixing groove is fixed at the support platform to provide a limit for the displacement of the dredging pipe, ensuring that the dredging pipe can only move forward and backward in the inner wall of the main pipeline corresponding to the main pipeline. The dredging pipe can be displaced forward and backward through the push rod, and the outer surface of the dredging pipe corresponding to the main pipeline adopts a knife-like cutting to separate the impurities from the inner surface of the main pipeline, so as to achieve the dredging effect without opening the pipeline. The operation can also be carried out during normal maintenance to ensure the cleanliness of the inside of the pipeline. This operation can be used to dredge when blocked. When the dredging pipe is still blocked after completing the displacement, it can be determined that there is a problem upstream of the valve or other pipelines, which reduces downtime, reduces production losses, and provides convenience. When the dredging pipe cannot complete the overall displacement, the bolts are opened to remove the fixing flange, and the displaced outer surface of the dredging pipe is separated from the main pipeline. The pipeline can be quickly disassembled during external activities to carry out related dredging operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] Example:

[0031] Reference Figure 1-3A blockage-proof electromagnetic flowmeter comprises a main pipeline 1, a positioning flange 2 is welded on the outer surface of one side of the main pipeline 1, a fixing flange 3 is movably connected to the outer surface of the positioning flange 2 away from the main pipeline 1, a bolt 4 is arranged on the outer surface of the fixing flange 3, a dredging pipe 5 is movably connected to the inner surface of the bolt 4, a push rod 6 is welded on the outer surface of the dredging pipe 5, and a fixing groove 7 is movably connected to the outer surface of the dredging pipe 5 corresponding to the push rod 6.

[0032] When in use, the main pipeline 1 of the equipment provides the main function of the electromagnetic flowmeter, the positioning flange 2 and the fixing flange 3 are fixed by bolts 4, and the fixing groove 7 is fixed at the support platform 8, which provides a limit for the displacement of the dredging pipe 5, ensuring that the dredging pipe 5 can only move forward and backward in the inner wall of the pipeline corresponding to the main pipeline 1. The dredging pipe 5 can be displaced forward and backward through the push rod 6. The outer surface of the dredging pipe 5 corresponding to the main pipeline 1 adopts a knife-shaped cutting to separate the impurities from the inner surface of the main pipeline 1, so as to achieve the dredging effect without opening the pipeline. The operation can also be carried out during normal maintenance to ensure the cleanliness of the inside of the pipeline. This operation can be used for dredging when blocked. When the dredging pipe 5 is still blocked after completing the displacement, it can be judged that there is a problem upstream of the valve or other pipelines, which reduces downtime, reduces production losses, and provides convenience. When the dredging pipe 5 cannot complete the overall displacement, the bolts 4 are opened to remove the fixing flange 3, and the displaced outer surface of the dredging pipe 5 is separated from the main pipeline 1, and the pipeline is quickly disassembled during external activities to carry out related dredging operations.

[0033] Reference Figure 1-3 A support platform 8 is welded on the outer surface of the fixed groove 7, and the support platform 8 and the corresponding outer surface of the main pipeline 1 are welded to each other. A label 9 is movably connected to the lower end of the outer surface of the support platform 8, and a connecting pipe 10 is welded on the outer surface of the support platform 8 corresponding to the dredging pipe 5.

[0034] The support platform 8 supports the fixing groove 7 to ensure the displacement of the silt removal pipe 5. The label 9 is convenient for maintenance personnel to query the relevant parameters of the flow meter. The connecting pipe 10 limits the silt removal pipe 5 to ensure the stability of the entire pipeline.

[0035] Reference Figure 1-3 A metal strip 11 is fixedly connected to the outer surface of the desilting pipe 5 , and a grounding wire 12 is fixedly connected to the outer surface of the support platform 8 .

[0036] The impurity blockage in the electromagnetic flowmeter is largely due to the magnetic adsorption of the impurities in the pipeline. As time goes by, the impurities become more and more, and the dredging pipe 5 moves into the inner surface of the main pipeline 1. The metal strip 11 and the grounding wire 12 are grounded to demagnetize the impurities, increasing the probability of impurity removal.

[0037] Reference Figure 1-3 An outer buffer tube 13 is welded to the outer surface of one side of the main pipeline 1 away from the positioning flange 2 , and a support plate 14 is fixedly connected to the outer surface of one end of the outer buffer tube 13 away from the main pipeline 1 .

[0038] The outer buffer tube 13 and the support plate 14 ensure that the pipeline can be connected to the main pipeline 1 for buffering, and can buffer the damage to the main pipeline 1 caused by impurities.

[0039] Reference Figure 1-3 A screen 15 is movably connected to the inner surface of the outer buffer tube 13 , and a second connecting tube 16 is movably connected to the upper surface of the support plate 14 beside the screen 15 .

[0040] The screen 15 blocks large particles of impurities and filters the impurities to avoid blockage inside the main pipeline 1. The second connecting pipe 16 ensures the sealing of the pipeline.

[0041] Reference Figure 1-3 The outer surface of the connecting pipe 16 is movably connected to a limiting block 17 , and a pull-out block 18 is welded on the upper surface of the limiting block 17 .

[0042] When there is a blockage in the equipment pipeline, the limit block 17 can be taken out by pulling out the block 18, and the second connecting pipe 16 can be displaced toward the inner surface of the tee pipe 19, so that the impurities in front of the screen 15 can be removed, and the screen 15 can also be taken out for further dredging or replacement.

[0043] Reference Figure 1-3 A tee pipe 19 is welded on the outer surface of one end of the support plate 14 away from the outer buffer tube 13 , and a blocking member 20 is provided on the inner surface of the tee pipe 19 .

[0044] The plugging member 20 is fixed by threads to block the hole above the tee pipe 19. When the upstream of the equipment is blocked, the impurities in the screen 15 can be sucked out by a negative pressure pump, or the screen 15 can be taken out to clear the silt in the pipeline.

[0045] Reference Figure 4 A magnetic induction coil 21 is fixedly connected to the inner surface of the main pipeline 1, an electrode 22 is fixedly connected to the inner surface of the main pipeline 1, an electromagnetic analysis body 23 is arranged on the upper surface of the main pipeline 1, and a display screen 24 is fixedly connected to the outer surface of the electromagnetic analysis body 23.

[0046] The magnetic field generated by the magnetic induction coil 21 generates voltage through the cutting of charged particles in the pipeline, and the electrode 22 receives the signal and transmits it to the electromagnetic analysis body 23. The internal circuit data of the electromagnetic analysis body 23 is processed and analyzed and the flow is displayed on the display screen 24, completing the main functions of the equipment.

[0047] The implementation principle of an anti-clogging electromagnetic flowmeter embodiment of the present application is:

[0048] When in use, the main pipeline 1 of the equipment provides the main function of the electromagnetic flowmeter, the positioning flange 2 and the fixing flange 3 are fixed by bolts 4, and the fixing groove 7 is fixed at the support platform 8, which provides a limit for the displacement of the dredging pipe 5, ensuring that the dredging pipe 5 can only move forward and backward in the inner wall of the pipeline corresponding to the main pipeline 1. The dredging pipe 5 can be displaced forward and backward through the push rod 6. The outer surface of the dredging pipe 5 corresponding to the main pipeline 1 adopts a knife-shaped cutting to separate the impurities from the inner surface of the main pipeline 1, so as to achieve the dredging effect without opening the pipeline. The operation can also be carried out during normal maintenance to ensure the cleanliness of the inside of the pipeline. This operation can be used for dredging when blocked. When the dredging pipe 5 is still blocked after completing the displacement, it can be judged that there is a problem upstream of the valve or other pipelines, which reduces downtime, reduces production losses, and provides convenience. When the dredging pipe 5 cannot complete the overall displacement, the bolts 4 are opened to remove the fixing flange 3, and the displaced outer surface of the dredging pipe 5 is separated from the main pipeline 1, and the pipeline is quickly disassembled during external activities to carry out related dredging operations.
