Description

Technical Field

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

[0002] Electromagnetic flowmeters, which measure the volumetric flow rate of conductive fluids based on Faraday's law of electromagnetic induction, have been widely used in many fields of industrial production, such as chemical, metallurgical, water treatment, and food processing, due to their advantages such as high measurement accuracy, good stability, and low pressure loss to the fluid.

[0003] However, in many industrial production scenarios, the fluids measured by electromagnetic flowmeters are often not pure and may contain various impurities. These impurities enter the measuring pipe of the electromagnetic flowmeter as the fluid flows, easily depositing and accumulating inside the pipe, gradually forming blockages, and thus affecting the normal operation of the electromagnetic flowmeter.

[0004] Therefore, it is necessary to invent an anti-clogging electromagnetic flowmeter to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging electromagnetic flowmeter to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging electromagnetic flowmeter, comprising an electromagnetic flowmeter body, a first end pipe, a second end pipe, and a filter mechanism. One end of the second end pipe is fixedly connected to the input end of the measurement channel of the electromagnetic flowmeter body. The filter mechanism includes a filter tube, which is fixedly connected between the first end pipe and the second end pipe. A connecting pipe is fixedly connected to the middle of the filter tube, and a loading ring is fixedly connected to the bottom end of the connecting pipe. A filter tank is disposed directly below the loading ring. The inner wall of the top of the filter tank is threadedly connected to the outer wall of the loading ring. A flow-blocking plate is fixedly connected inside the filter tube. The bottom end of the flow-blocking plate passes through the connecting pipe and extends into the loading ring. A slot is provided on each side of the inner wall of the filter tank. A filter plate is engaged between the two slots. The filter plate is located directly below the flow-blocking plate. A first sealing gasket is fixedly connected to the bottom of the flow-blocking plate, and the first sealing gasket is in interference contact with the top of the filter plate.

[0007] Preferably, one end of the first end pipe is used to connect to the pipe of the fluid being measured. The fluid being measured enters the filter mechanism through the first end pipe and then flows into the measurement channel of the electromagnetic flowmeter body through the second end pipe.

[0008] Preferably, the flow baffle separates the inside of the filter tube into two independent pipe spaces: the first pipe space is for unfiltered fluid to flow through, and the second pipe space is for filtered fluid to flow through.

[0009] Preferably, the filter plate divides the interior of the filter tank into two independent tank spaces: a first tank space and a second tank space. The first tank space is connected to a first pipeline space, and the second tank space is connected to a second pipeline space.

[0010] Preferably, after the fluid to be measured is introduced into the filtration mechanism through the No. 1 end pipe, the unfiltered fluid enters the No. 1 tank space inside the filter tank through the No. 1 pipe space inside the filter pipe. After passing through the filter plate to remove impurities, the filtered fluid enters the No. 2 pipe space inside the filter pipe through the No. 2 tank space inside the filter tank, and finally flows into the measurement channel inside the electromagnetic flowmeter body through the No. 2 end pipe.

[0011] Preferably, a second sealing gasket is fixedly connected to the bottom of the loading ring, and an annular step is provided on the inner wall of the filter tank, with the second sealing gasket in interference contact with the annular step.

[0012] Preferably, the number of the filtration mechanisms is set to two, and the filter tubes of the two filtration mechanisms are arranged vertically in parallel.

[0013] Preferably, a valve is installed at each end of the filter tube, and the switching operation between the two filter mechanisms can be realized by controlling the opening and closing of the corresponding valves.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. By setting a filter mechanism before the input end of the measurement channel of the electromagnetic flowmeter body, impurities in the measured fluid can be intercepted, preventing impurities from entering the measurement pipe of the electromagnetic flowmeter, depositing and accumulating to form a blockage, thereby ensuring the normal operation of the electromagnetic flowmeter. 2. By setting up two switchable filter mechanisms, operators can switch between the two filter mechanisms by controlling the opening and closing of the corresponding valves, putting the backup filter mechanism into use. This avoids measurement interruption caused by blockage of a single filter mechanism and ensures the continuous and stable operation of the electromagnetic flowmeter. Attached Figure Description

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5 The illustrated anti-clogging electromagnetic flowmeter includes an electromagnetic flowmeter body 1, a first end pipe 2, a second end pipe 3, and a filter mechanism. One end of the second end pipe 3 is fixedly connected to the input end of the measurement channel of the electromagnetic flowmeter body 1. The filter mechanism includes a filter pipe 4, which is fixedly connected between the first end pipe 2 and the second end pipe 3. A connecting pipe 5 is fixedly connected to the middle of the filter pipe 4, and a loading ring 6 is fixedly connected to the bottom end of the connecting pipe 5. A filter tank 7 is arranged directly below the loading ring 6. The inner wall of the top of the filter tank 7 is threadedly connected to the outer wall of the loading ring 6. A flow-blocking plate 8 is fixedly connected inside the filter pipe 4. The bottom end of the flow-blocking plate 8 passes through the connecting pipe 5 and extends into the loading ring 6. A slot is opened on each side of the inner wall of the filter tank 7, and a filter plate 9 is engaged between the two slots. The filter plate 9 is located directly below the flow-blocking plate 8. A first sealing gasket 10 is fixedly connected to the bottom of the flow-blocking plate 8, and the first sealing gasket 10 is in interference contact with the top of the filter plate 9.

[0019] In one aspect of this embodiment, one end of the first end pipe 2 is used to connect to the pipe of the fluid to be measured. The fluid to be measured enters the filter mechanism through the first end pipe 2, and then flows into the measurement channel of the electromagnetic flowmeter body 1 through the second end pipe 3.

[0020] The baffle plate 8 divides the inside of the filter tube 4 into two independent pipe spaces: the first pipe space 11 and the second pipe space 12. The first pipe space 11 is for the flow of unfiltered fluid, and the second pipe space 12 is for the flow of filtered fluid.

[0021] The filter plate 9 divides the interior of the filter tank 7 into two independent tank spaces: a first tank space 13 and a second tank space 14. The first tank space 13 is connected to the first pipeline space 11, and the second tank space 14 is connected to the second pipeline space 12.

[0022] After the fluid to be measured is introduced into the filtration mechanism through the No. 1 end pipe 2, the unfiltered fluid enters the No. 1 tank space 13 inside the filter tank 7 through the No. 1 pipe space 11 inside the filter pipe 4. After passing through the filter plate 9, the impurities in the fluid are filtered out. The filtered fluid enters the No. 2 pipe space 12 inside the filter pipe 4 through the No. 2 tank space 14 inside the filter tank 7, and finally flows into the measurement channel inside the electromagnetic flowmeter body 1 through the No. 2 end pipe 3.

[0023] The bottom of the loading ring 6 is fixedly connected to a second sealing gasket 15. The inner wall of the filter tank 7 is provided with an annular step. The second sealing gasket 15 is in interference contact with the annular step to ensure the sealing of the connection.

[0024] The filter mechanism is set to two, with the filter tubes 4 of the two filter mechanisms arranged parallel to each other vertically. A valve 16 is installed at each end of the filter tube 4. The switching operation between the two filter mechanisms can be realized by controlling the opening and closing of the corresponding valves 16. The design of switching between the two filter mechanisms avoids the measurement interruption problem caused by the blockage of a single filter mechanism, and ensures that the electromagnetic flowmeter can operate continuously and stably.

[0025] The electromagnetic flowmeter body 1 and valve 16 mentioned above are existing technology products, and their specific structures and functions will not be described in detail here.

[0026] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-5 When using this utility model, firstly, connect one end of the first end pipe 2 to the fluid pipeline to be measured in a stable manner to ensure that the fluid can flow smoothly into the electromagnetic flowmeter system. The fluid to be measured enters the filter mechanism through the first end pipe 2, at which time the fluid is in an unfiltered state.

[0027] After the fluid enters the filtration mechanism, it first reaches the filter tube 4. The filter tube 4 is equipped with a flow baffle 8, which divides the filter tube 4 into an independent first pipe space 11 and a second pipe space 12. The first pipe space 11 is for the flow of unfiltered fluid, and the second pipe space 12 is for the flow of filtered fluid. Unfiltered fluid enters the first tank space 13 inside the filter tank 7 from the first pipe space 11 through the connecting pipe 5. A slot is opened on each side of the inner wall of the filter tank 7, and a filter plate 9 is snapped between the two slots. The filter plate 9 is located directly below the flow baffle 8. A first sealing gasket 10 is fixedly connected to the bottom of the flow baffle 8. The first sealing gasket 10 is in interference contact with the top of the filter plate 9 to further ensure that the fluid can only be filtered through the filter plate 9 and will not bypass through the gaps. After the fluid enters the first tank space 13, it passes through the filter plate 9 to remove impurities. The filtered fluid then enters the second pipe space 12 inside the filter pipe 4 through the second tank space 14. Finally, the filtered fluid flows into the measurement channel inside the electromagnetic flowmeter body 1 through the second end pipe 3. The electromagnetic flowmeter body 1 measures the volumetric flow rate of the fluid according to Faraday's law of electromagnetic induction. This electromagnetic flowmeter is equipped with two filtration mechanisms. The filter tubes 4 of the two filtration mechanisms are arranged parallel to each other, and a valve 16 is installed at each end of the filter tube 4. During normal use, one filtration mechanism is in working condition, while the other is in standby. When the filter plate 9 of the working filtration mechanism becomes clogged due to long-term use, affecting the normal flow of fluid, the switching operation between the two filtration mechanisms can be realized by controlling the opening and closing of the corresponding valve 16. The standby filtration mechanism is put into use, and the clogged filtration mechanism is cleaned at the same time, thereby ensuring that the electromagnetic flowmeter can operate continuously and stably.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
