Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic flowmeters, and in particular to an intelligent ultra-high pressure electromagnetic flowmeter with an anti-clogging function. Background Art

[0002] The electromagnetic flowmeter is a flowmeter made based on the principle of electromagnetic induction. It converts the induced potential signal generated by the particles in the fluid cutting the magnetic lines into a flow signal and displays it on the display instrument, thereby realizing intelligent measurement of the flow rate. It is widely used in industry, agriculture, medicine, food and other industries.

[0003] According to the Chinese patent with patent number CN110567541A: an electromagnetic flowmeter drives the fan blades to rotate during the movement of the fluid, and the fan blades drive the scraper to scrape the inner wall of the electromagnetic flowmeter to remove the dirt on the inner wall, and cut the suspended impurities into smaller particles through the wire mesh, so that the signal of the electromagnetic flowmeter is more stable; however, the fan blades and scrapers and other components are located in the measuring pipe of the electromagnetic flowmeter, which will also cause certain interference and obstruction to the signal transmission, resulting in inaccurate measurement results.

[0004] And when the fluid contains some impurities that cannot be cut by the wire mesh, the impurities will continue to stick to the wire mesh under the drive of the water flow, thus blocking the water flow and other suspended impurities. Summary of the invention

[0005] In order to overcome the shortcomings that the existing fan blades, scrapers and other components are located in the measuring pipe of the electromagnetic flowmeter, which interferes with the signal transmission and causes inaccurate measurement results, and when the fluid contains some impurities that cannot be cut by the wire mesh, the impurities will continue to stick to the wire mesh under the drive of the water flow, thereby blocking the water flow and other suspended impurities, the present invention provides an intelligent ultra-high pressure electromagnetic flowmeter with anti-blocking function.

[0006] The technical solution of the present invention is: an intelligent ultra-high pressure electromagnetic flowmeter with anti-clogging function, including a water pipe, a flow detection component and an inner lining; the flow detection component is connected to the outside of the water pipe; the inner lining is connected to the inside of the water pipe; the inner lining is located within the coverage of the flow detection component; it also includes a first driving member, a cleaning ring, a filter, a vibrator and a deformation component; a plurality of first driving members are fixedly connected in the water pipe; a cleaning ring is commonly fixedly connected to the output ends of all first driving members; a filter is fixedly connected to the cleaning ring, and the filter is located on the left side of the inner lining; a vibrator is connected to the middle of the filter, and the filter is fixedly connected to the output end of the vibrator.

[0007] More preferably, the filter screen is made of a deformable material.

[0008] More preferably, the deformation assembly includes a fixed block and a second driving member; the cleaning ring is fixedly connected to the fixed block; the second driving member is fixedly connected to the fixed block; and the output end of the second driving member is fixedly connected to the vibrator.

[0009] More preferably, the first driving member and the second driving member are both treated to be waterproof and pressure-resistant.

[0010] More preferably, a mounting block is further included; a debris discharge port is provided at the lower side of the water pipe; and the mounting block is detachably connected to the debris discharge port.

[0011] More preferably, a sealing strip is provided on the mounting block.

[0012] More preferably, the side of the fixing block in contact with the water flow is configured as a pointed slope.

[0013] More preferably, the inner side of the liner is coated with a wear-resistant coating.

[0014] More preferably, the cleaning ring is made of wear-resistant rubber material.

[0015] More preferably, a magnetic block is further included; the mounting block is fixedly connected with the magnetic block.

[0016] The beneficial effects are as follows: the present invention realizes interception of large impurities in the water flow by the filter screen, and then under the impact of the water flow, the suspended impurities are cut into small pieces by the filter screen, which effectively reduces the adhesion ability of the suspended impurities, thereby preventing the suspended impurities from accumulating in the lining and even causing blockage in the lining, and effectively avoids the situation that the detection data is inaccurate due to the uneven particle size of the impurities passing through the lining, thereby affecting the measurement effect of the flow detection component; By deforming the filter into a hemispherical shape convex to the left, and driving the filter to vibrate rapidly through the output end of the vibrator, the filter is temporarily separated from the suspended impurities it intercepts. Then, driven by the water flow, the suspended impurities can move along the inclined surface of the filter to the edge of the filter, thereby effectively preventing them from continuously adhering to the middle area of ​​the filter and affecting the water flow through the filter. The cleaning ring is used to scrape the inner wall of the liner so that the dirt adhering to the inner wall of the liner is gradually scraped to the right by the cleaning ring. At the same time, the filter screen deformed into a plane cooperates with the cleaning ring to enhance the pushing effect of the dirt. Before the water flows through the lining, the strong magnetic particles in the water can be adsorbed by the magnetic block to prevent the strong magnetic particles from passing through the lining with the water flow and affecting the detection data of the flow detection component.

[0019] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] Example 1 An intelligent ultra-high pressure electromagnetic flowmeter with anti-clogging function, such as Figure 1-Figure 4 As shown, it includes a water pipe 1, a flow detection component 2 and an inner liner 3; the outer side of the water pipe 1 is connected to the flow detection component 2; the inner side of the water pipe 1 is connected to the inner liner 3; the inner liner 3 is located within the coverage of the flow detection component 2; It also includes a first driving member 4, a cleaning ring 5, a filter 6, a vibrator 7 and a deformation component; two first driving members 4 are fixedly connected to the left part of the water pipe 1, and the first driving member 4 is an electric push rod; the output ends of all the first driving members 4 are commonly fixedly connected to a cleaning ring 5; the cleaning ring 5 is fixedly connected to a filter 6, and the filter 6 is located on the left side of the lining 3; the middle part of the filter 6 is connected to the vibrator 7, and the filter 6 is fixedly connected to the output end of the vibrator 7.

[0021] The filter screen 6 is configured to be a deformable material.

[0022] The deformation assembly includes a fixed block 101 and a second driving member 102 ; the fixed block 101 is fixedly connected to the cleaning ring 5 ; the second driving member 102 is fixedly connected to the fixed block 101 , and the second driving member 102 is an electric push rod; the output end of the second driving member 102 is fixedly connected to the vibrator 7 .

[0023] The first driving member 4 and the second driving member 102 are both treated to be waterproof and pressure-resistant, which helps to ensure that the first driving member 4 and the second driving member 102 can be used normally in water.

[0024] It also includes a mounting block 201 ; a debris discharge port 1001 is provided at the lower side of the water pipe 1 ; the debris discharge port 1001 is detachably connected to the mounting block 201 , and the debris discharge port 1001 is blocked by the mounting block 201 .

[0025] A sealing strip is provided on the mounting block 201 to ensure the sealing effect of the mounting block 201 on the impurity discharge port 1001 .

[0026] The side of the fixing block 101 in contact with the water flow is configured as a pointed slope to achieve diversion of the water flow and prevent the water flow from exerting a large driving force on the fixing block 101 .

[0027] The inner side of the liner 3 is coated with a wear-resistant coating.

[0028] The cleaning ring 5 is made of wear-resistant rubber material to increase the friction between the cleaning ring 5 and the liner 3, thereby enhancing the cleaning effect of the cleaning ring 5 on the liner 3, while avoiding significant wear between the cleaning ring 5 and the liner 3, so as to extend the service life of the cleaning ring 5 and the liner 3.

[0029] During operation, the left side of the water pipe 1 is connected to the water inlet pipe, and the right side of the water pipe 1 is connected to the water outlet pipe. When water flows through the lining 3, the flow rate of the water can be detected by the electromagnetic detection device in the flow detection component 2, and the initial cleaning ring 5 and the filter 6 are located on the left side of the lining 3. Different from the prior art, the cleaning ring 5 and the filter 6 and other parts will not interfere with and block the signal transmission, and the suspended impurities in the water flow are intercepted by the filter 6, and then driven by the impact of the water flow, the suspended impurities are cut into small pieces by the filter 6, which effectively reduces the adhesion ability of the suspended impurities, thereby avoiding the accumulation of suspended impurities in the lining 3, and even causing blockage in the lining 3.

[0030] At the same time, since the volume of suspended impurities in the water varies greatly, that is, the particle size of impurities passing through the lining 3 is uneven, it will cause certain interference to the normal generation and transmission of the induced potential signal on the electrode, which may easily lead to inaccurate detection data. Therefore, the suspended impurities in the water are broken into relatively uniform small pieces through the filter 6, effectively avoiding the situation where the uneven particle size of impurities passing through the lining 3 leads to inaccurate detection data, thereby affecting the measurement effect of the flow detection component 2.

[0031] In order to avoid the existence of impurities that cannot be cut by the filter screen 6, so that they continue to adhere to the filter screen 6, thereby affecting the water flow and other suspended impurities passing through the filter screen 6, such as Figure 2 As shown, the middle part of the filter screen 6 is pulled to the left by the second driving member 102, so that the filter screen 6 is deformed into a hemispherical shape convex to the left, so that the impurities that cannot be cut by the filter screen 6 can move along the inclined surface of the filter screen 6 to the edge of the filter screen 6, thereby effectively preventing them from continuing to adhere to the middle area of ​​the filter screen 6 and affecting the water flow and other suspended impurities passing through the filter screen 6.

[0032] Taking into account that the water flow passing through the water pipe 1 and the liner 3 is in a high-pressure state, when the water flows in the water pipe 1 and the liner 3, the water flow has a large thrust on the impurities in the filter screen 6, so that the impurities that cannot be cut will be tightly attached to the filter screen 6 under the action of the water flow, resulting in the impurities that cannot be cut being difficult to move along the inclined surface of the filter screen 6 to the edge of the filter screen 6, resulting in the impurities that cannot be cut still blocking the water flow and other suspended impurities. Therefore, after the middle part of the filter screen 6 is pulled to the left by the second driving member 102, the filter screen 6 is deformed into a hemispherical shape convex to the left, and at the same time, the filter screen 6 is driven by the output end of the vibrator 7 to shake rapidly, so that the filter screen 6 and the suspended impurities it intercepts are temporarily separated, and then, driven by the water flow, the suspended impurities can move along the inclined surface of the filter screen 6 to the edge of the filter screen 6, thereby effectively preventing them from continuing to adhere to the middle area of ​​the filter screen 6 and affecting the water flow through the filter screen 6.

[0033] After the present invention has been used for a period of time, a layer of dirt may be adhered and accumulated on the inner wall of the liner 3. In order to prevent the dirt from continuing to remain on the liner 3 and interfering with the flow measurement of the flow detection component 2, such as Figure 3 As shown, the first driving member 4 is controlled to drive the cleaning ring 5 and the filter screen 6 to move to the right, and then the cleaning ring 5 drives the fixing block 101 and the second driving member 102 to move to the right, so that the inner wall of the liner 3 is scraped by the cleaning ring 5, so that the dirt adhered to the inner wall of the liner 3 is gradually scraped to the right by the cleaning ring 5, and then the detached dirt is gradually taken away by the water flow, and at the same time, the second driving member 102 is controlled to push the vibrator 7 to the right, and the vibrator 7 drives the middle part of the filter screen 6 to move to the right, so that the filter screen 6 is adaptively deformed into a plane, and the size of the mesh hole on the filter screen 6 is also reduced accordingly, so that the vibrator 7, the filter screen 6 and the cleaning ring 5 cooperate to enhance the pushing effect of the dirt.

[0034] Further, after the cleaning ring 5 moves to the right of the liner 3, the first driving member 4 is controlled to drive the cleaning ring 5 and the parts connected thereto to reset to the left, so that the suspended impurities that have not been broken are pushed to the left through the cleaning ring 5 and the filter screen 6, and then Figure 4As shown, the mounting block 201 is removed from the water pipe 1, so that the mounting block 201 releases the blockage of the impurity discharge port 1001, and the water flow in the water pipe 1 can flow out from the impurity discharge port 1001, so that the impurities on the left side of the filter screen 6 can be taken out by the water flow, and at this time the filter screen 6 is in a planar shape, which effectively prevents the filter screen 6 from blocking the downward movement of suspended impurities. At the same time, the filter screen 6 is driven by the vibrator 7 to shake, which effectively promotes the impurities to flow downward to the impurity discharge port 1001 with the water flow, and avoids the existence of some impurities still adhering to the filter screen 6, thereby realizing the cleaning of the suspended impurities that have not been broken. After the suspended impurities on the left side of the filter screen 6 are discharged, the mounting block 201 can be installed on the water pipe 1, and the impurity discharge port 1001 can be re-blocked to perform normal flow detection.

[0035] Example 2 On the basis of Example 1, Figure 2 and Figure 3 As shown, a magnetic block 202 is also included; the magnetic block 202 is fixedly connected to the mounting block 201.

[0036] When there are strong magnetic particles in the water, it will affect the magnetic field detection of the flow detection component 2, resulting in inaccurate detection data. Therefore, in the present invention, before the water flows through the lining 3, the strong magnetic particles in the water can be adsorbed by the magnetic block 202 to prevent the strong magnetic particles from passing through the lining 3 with the water flow and affecting the detection data of the flow detection component 2. When the mounting block 201 is removed from the water pipe 1, the strong magnetic particles adsorbed on the magnetic block 202 can be cleaned to ensure the adsorption effect of the magnetic block 202 on the strong magnetic particles, thereby effectively ensuring the measurement effect of the flow detection component 2.
