Description

Technical Field

[0001] This invention relates to the field of filtration technology, specifically to a converter valve cooling water operation and maintenance equipment and its usage method. Background Technology

[0002] The external cooling water system of ultra-high voltage direct current converter stations is an important part of the direct current transmission project. The raw water quality of the external cooling water system of domestic direct current converter stations is generally poor, and the scaling of the external cooling system pipes and cooling towers is serious. Some filtration devices have been designed for filtration.

[0003] For example, Chinese patent CN215721682U describes a DC converter valve cooling device, relating to the field of power transmission equipment technology. Specifically, it includes a water pipe and an installation groove. The installation groove is located at the top of the side of the water pipe. An installation block is installed inside the installation groove. An inlet plate and a filter screen are vertically fixed to the inner wall of the installation block, with the filter screen located to the right of the inlet plate. A movable groove is located on the inner wall of the installation block near the inlet plate, and a movable liquid plate is movably connected inside the movable groove. Both the movable liquid plate and the inlet plate have through holes on their surfaces. By setting up the installation block, filter screen, and movable clamp structure, the scale in the water pipe is filtered, collected, and quickly removed. By setting up the movable liquid plate and adjusting nut, rotating the adjusting nut causes the connecting rod to move up and down, thereby causing the through holes on the movable liquid plate to be misaligned with the through holes on the inlet plate, thus preventing scale from leaking out from the through holes when removing the installation block.

[0004] However, the above structure has the following problems: First, the above structure requires shutdown when cleaning or replacing the filter screen, which is not suitable for the continuous use requirements of UHVDC converter stations. Second, the operation of discharging the cleaned impurities is relatively troublesome and not conducive to practical use.

[0005] Based on this, the present invention designs a converter valve cooling water operation and maintenance equipment and its usage method to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a converter valve cooling water operation and maintenance equipment and its usage method.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A converter valve cooling water operation and maintenance device includes an inlet pipe and an outlet pipe;

[0009] The inlet pipe is symmetrically and fixedly connected to a self-cleaning filter assembly for alternating filtration.

[0010] The self-cleaning filter assembly includes an outer filter cylinder, an automatic venting assembly, a first inclined tube, a second inclined tube, a sewage discharge assembly, a filter assembly, a support ring, and an impact assembly. The second inclined tube is fixedly connected to the side wall of the inlet pipe. The second and first inclined tubes are fixedly connected to the side wall of the outer filter cylinder. The first inclined tube is fixedly connected to the side wall of the outlet pipe. The inner wall of the outer filter cylinder is fixedly connected to the support ring. The filter assembly is in close contact with the top of the support ring. An impact assembly is connected to the top of the outer filter cylinder and is connected to the filter assembly. The filter assembly is located between the first and second inclined tubes and is slidably connected to the inner wall of the outer filter cylinder. The top of the impact assembly is fixedly connected to the automatic venting assembly. The sewage discharge assembly is fixedly connected to the bottom of the outer filter cylinder.

[0011] A regulating component for adjusting the water flow direction is connected between the inlet pipe and the outlet pipe;

[0012] The inlet and outlet pipes are also connected to differential pressure monitoring components for real-time differential pressure monitoring.

[0013] Furthermore, the impact assembly includes a second cover plate, a mounting rod, an electromagnet, an iron rod, a spring, a mounting sleeve, a pressure plate, and a linkage assembly. The second cover plate is threaded onto the top of the outer filter cylinder. The top of the inner part of the second cover plate is fixedly connected to the top of the mounting rod. The mounting sleeve is fixedly installed at the bottom of the mounting rod. The electromagnet is fixedly installed at the bottom of the mounting rod and is located inside the mounting sleeve. The upper and lower ends of the spring are fixedly connected to the bottom of the mounting sleeve and the top of the pressure plate, respectively. The top of the pressure plate is fixedly connected to the bottom of the iron rod, and the upper end of the iron rod is slidably connected to the inner wall of the lower end of the mounting sleeve. The bottom of the pressure plate is connected to the linkage assembly. The linkage assembly is slidably connected to the filter assembly. The automatic exhaust assembly is fixedly connected to the top of the second cover plate.

[0014] Furthermore, the linkage component includes a second anti-detachment ring and a third sliding rod, with the bottom of the iron rod fixedly connected to the top of the third sliding rod, and the bottom of the third sliding rod passing through the sewage discharge component and then connected to the second anti-detachment ring.

[0015] Furthermore, the filter assembly includes a mounting ring and a filter screen. The outer wall of the mounting ring is slidably connected to the inner wall of the filter outer cylinder, and the inner wall of the mounting ring is slidably connected to the outer wall of the filter screen. The filter screen is slidably connected to the third slide rod through a sliding hole. The mounting ring is located below the pressure plate, and the top of the mounting ring is in contact with the top of the support ring.

[0016] Furthermore, the automatic exhaust assembly includes a straight cylinder, a sealing assembly, a venting assembly, and a floating propulsion assembly. The straight cylinder is fixedly connected to the top of the second cover plate. The venting assembly, the sealing assembly, and the floating propulsion assembly are fixedly installed on the inner wall of the straight cylinder from top to bottom. The upper and lower ends of the sealing assembly are respectively fitted and connected to the venting assembly and the floating propulsion assembly.

[0017] Furthermore, the differential pressure monitoring component includes a first water pressure sensor, a second water pressure sensor, and a controller. The first water pressure sensor is fixedly installed on the side wall of the inlet pipe, and the second water pressure sensor is fixedly installed on the side wall of the outlet pipe. Both the first and second water pressure sensors are communicatively connected to the controller. The controller is also communicatively connected to the regulating component, the self-cleaning filter component, and the electromagnet.

[0018] Furthermore, the water inlet pipe is also connected to a straight-tube flushing assembly for rinsing scale and other deposits that adhere to the inner wall of the outer filter cylinder after the filter screen has been cleaned. The flushing assembly is connected to the controller.

[0019] Furthermore, the flushing assembly includes a first pipe, a second pipe, a second control valve, and a straight pipe. The second pipe is fixedly connected to the inlet pipe and to the input end of the second control valve. The two sets of first pipes are fixedly connected to the two output ends of the second control valve. The two sets of straight pipes are fixedly connected to the two sets of first pipes one-to-one. The straight pipes are located inside the filter outer cylinder, with the top of the straight pipes sealed. Spray holes are evenly distributed at the upper end of the straight pipes.

[0020] Furthermore, the regulating component includes a drive component, an assembly component, and a rotating sealing component. The two sets of rotating sealing components are connected to the inlet pipe and the outlet pipe, respectively. The two sets of rotating sealing components are connected to each other through the assembly component. The drive component is connected to one of the rotating sealing components and is connected to the inlet pipe or the outlet pipe.

[0021] A method for using a converter valve cooling water operation and maintenance equipment includes the following steps:

[0022] Step 1: Adjust the component to rotate until the first and second inclined tubes of the self-cleaning filter component on the inlet pipe side are connected, and the first and second inclined tubes of the self-cleaning filter component on the inlet pipe side are in flow.

[0023] Step 2: The differential pressure monitoring component monitors the real-time differential pressure and the rate of change of the real-time differential pressure between the first and second inclined tubes of the self-cleaning filter assembly on one side of the inlet pipe. When the real-time differential pressure exceeds the cleaning threshold or the rate of change of the real-time differential pressure exceeds the set value, the adjusting component rotates to block the first and second inclined tubes of the self-cleaning filter assembly on one side of the inlet pipe. The drain component opens to drain the water from the outer filter cylinder. The impact component is activated, and it impacts the filter assembly, generating an instantaneous impact force. The filter assembly generates a local stress wave, which peels off the hard scale and adhering substances at the bottom of the filter assembly. The peeled hard scale and adhering substances fall into the drain component and are discharged by gravity. The first and second inclined tubes of the self-cleaning filter assembly on the other side of the inlet pipe are in the open state, and the filter assembly on the other side of the inlet pipe performs normal filtration.

[0024] Step 3: The differential pressure monitoring component monitors the real-time differential pressure and the rate of change of the real-time differential pressure between the first and second inclined tubes of the self-cleaning filter assembly on the other side of the inlet pipe. When the real-time differential pressure exceeds the cleaning threshold or the rate of change of the real-time differential pressure exceeds the set value, the filter assembly of the self-cleaning filter assembly on the other side of the inlet pipe cleans itself, and the filter assembly of the self-cleaning filter assembly on one side of the inlet pipe is restarted. The flow pump connected to the inlet pipe controls the flow rate at the standard flow rate. The differential pressure monitoring component continues to monitor the real-time differential pressure between the first and second inclined tubes on one side of the inlet pipe. When the real-time differential pressure exceeds the initial differential pressure, the filter assembly of the self-cleaning filter assembly on one side of the inlet pipe continues to filter. When the real-time differential pressure is less than the initial differential pressure, the filter assembly of the self-cleaning filter assembly on one side of the inlet pipe needs to be replaced. This allows for accurate monitoring of the filtration performance of the filter assembly, which is beneficial for practical use.

[0025] Beneficial effects: This invention utilizes the first and second inclined tubes of the self-cleaning filter assembly on one side of the inlet pipe for water flow. A differential pressure monitoring component monitors the real-time differential pressure and its rate of change between the two tubes. When the real-time differential pressure exceeds the cleaning threshold or the rate of change exceeds a set value, the adjusting component rotates to block the first and second inclined tubes of the self-cleaning filter assembly on the inlet pipe side. The drain component opens to discharge water from the outer filter cylinder. The impact component then contacts the filter assembly, impacting it and generating an instantaneous impact force. This creates a localized stress wave in the filter assembly, peeling off hard scale and deposits from the bottom. The peeled scale and deposits fall into the drain component and are discharged by gravity. Meanwhile, the first and second inclined tubes of the self-cleaning filter assembly on the other side of the inlet pipe remain open, allowing normal filtration. This alternating filtration and cleaning of scale and deposits enables continuous processing without downtime. The system is designed for practical use. When the self-cleaning filter assembly on the other side of the inlet pipe needs cleaning to remove scale and deposits, the adjustment mechanism is rotated to block the first and second inclined tubes of the self-cleaning filter assembly on the other side of the inlet pipe. The first and second inclined tubes of the self-cleaning filter assembly on the inlet pipe side remain open. Water entering the first inclined tube, the outer filter cylinder, and the second inclined tube will rise to the outer filter cylinder due to the low air density, and then be discharged through the automatic exhaust component. This prevents gas from entering the outlet pipe through the first inclined tube, reducing the possibility of water hammer. The flow pump connected to the inlet pipe controls the flow rate at the standard flow rate. The differential pressure monitoring component continues to monitor the real-time differential pressure between the first and second inclined tubes on the inlet pipe side. When the real-time differential pressure is greater than the initial differential pressure, the filter assembly on the inlet pipe side continues to filter. When the real-time differential pressure is less than the initial differential pressure, the filter assembly on the inlet pipe side needs to be replaced. This system allows for accurate monitoring of the filter assembly's performance, which is beneficial for practical use. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] The present invention will be further described below with reference to embodiments.

[0041] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0042] Example 1, please refer to the appendix of the instruction manual. Figures 1-3 A converter valve cooling water operation and maintenance device, comprising an inlet pipe 1 and an outlet pipe 2;

[0043] The side wall of the inlet pipe 1 is symmetrically connected with a self-cleaning filter assembly 5 for alternating filtration;

[0044] The self-cleaning filter assembly 5 includes a filter outer cylinder 51, an automatic venting assembly 52, a first inclined tube 54, a second inclined tube 57, a sewage discharge assembly, a filter assembly, a support ring 515, and an impact assembly. The second inclined tube 57 is fixedly connected to the side wall of the inlet pipe 1. The second inclined tube 57 and the first inclined tube 54 are fixedly connected to the side wall of the filter outer cylinder 51. The first inclined tube 54 is fixedly connected to the side wall of the outlet pipe 2. The inner wall of the filter outer cylinder 51 is fixedly connected to the support ring 515. The filter assembly is in close contact with the top of the support ring 515. The top of the filter outer cylinder 51 is connected to the impact assembly, and the impact assembly is connected to the filter assembly. The filter assembly is located between the first inclined tube 54 and the second inclined tube 57 and is slidably connected to the inner wall of the filter outer cylinder 51. The top of the impact assembly is fixedly connected to the automatic venting assembly 52. ​​The sewage discharge assembly is fixedly connected to the bottom of the filter outer cylinder 51.

[0045] A regulating component 4 for adjusting the water flow direction is connected between the inlet pipe 1 and the outlet pipe 2;

[0046] Differential pressure monitoring components 3 for real-time differential pressure monitoring are also connected to the inlet pipe 1 and the outlet pipe 2.

[0047] The first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter assembly 5 on one side of the inlet pipe 1 are inflow. The differential pressure monitoring component 3 monitors the real-time differential pressure and the real-time differential pressure change rate between the first inclined tube 54 and the second inclined tube 57. When the real-time differential pressure is greater than the cleaning threshold or the real-time differential pressure change rate is greater than the set value, the adjusting component 4 rotates to block the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter assembly 5 on one side of the inlet pipe 1. The sewage discharge component opens to discharge the water in the filter outer cylinder 51. The impact component is activated, and the impact component connects with the filter assembly. The filter element is impacted, generating an instantaneous impact force. This creates a localized stress wave that peels off hard scale and deposits from the bottom of the filter element. The peeled scale and deposits then fall into the drain assembly and are discharged by gravity. Meanwhile, the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter element 5 on the other side of the inlet pipe 1 are open. The filter element of the self-cleaning filter element 5 on the other side of the inlet pipe 1 performs normal filtration, achieving alternating filtration and alternating cleaning of scale and deposits. This continuous treatment eliminates the need for downtime, which is beneficial for practical use. When the self-cleaning filter assembly 5 on the other side of water pipe 1 needs to be cleaned of scale and adhering substances, the adjusting component 4 is rotated to block the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter assembly 5 on the other side of water inlet pipe 1. The first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter assembly 5 on the side of water inlet pipe 1 are open. When water enters the first inclined tube 54, the outer filter cylinder 51 and the second inclined tube 57, due to the low air density, the air will rise to the top of the outer filter cylinder 51 and then be discharged through the automatic exhaust component 52, preventing gas from entering through the first inclined tube 54. The flow rate is controlled at the standard flow rate by the flow pump connected to the inlet pipe 1. The differential pressure monitoring component 3 continues to monitor the real-time differential pressure between the first inclined pipe 54 and the second inclined pipe 57 on one side of the inlet pipe 1. When the real-time differential pressure is greater than the initial differential pressure, the filter component of the self-cleaning filter component 5 on the side of the inlet pipe 1 continues to filter. When the real-time differential pressure is less than the initial differential pressure, the filter component of the self-cleaning filter component 5 on the side of the inlet pipe 1 needs to be replaced. This allows for accurate monitoring of the filtration performance of the filter components, which is beneficial for practical use.

[0048] Please refer to the instruction manual appendix. Figures 1-9The impact assembly includes a second cover plate 53, a mounting rod 58, an electromagnet 59, an iron rod 510, a spring 511, a mounting sleeve 512, a pressure plate 513, and a linkage assembly. The second cover plate 53 is threaded onto the top of the filter outer cylinder 51. The top inner part of the second cover plate 53 is fixedly connected to the top of the mounting rod 58. The mounting sleeve 512 is fixedly installed at the bottom of the mounting rod 58. The electromagnet 59 is fixedly installed at the bottom of the mounting rod 58 and is located inside the mounting sleeve 512. The upper and lower ends of the spring 511 are fixedly connected to the bottom of the mounting sleeve 512 and the top of the pressure plate 513, respectively. The top of the pressure plate 513 is fixedly connected to the bottom of the iron rod 510, and the upper end of the iron rod 510 is slidably connected to the inner wall of the lower end of the mounting sleeve 512. The bottom of the pressure plate 513 is connected to the linkage assembly. The linkage assembly is slidably connected to the filter assembly. The automatic exhaust assembly 52 is fixedly connected to the top of the second cover plate 53.

[0049] The connection between the mounting sleeve 512 and the mounting rod 58 is a threaded connection.

[0050] The lower inner wall of the mounting sleeve 512 is slidably connected to the outer wall of the iron rod 510 through a sealing ring.

[0051] The linkage component includes a second anti-detachment ring 517 and a third slide rod 518, with the bottom of the iron rod 510 fixedly connected to the top of the third slide rod 518, and the bottom of the third slide rod 518 passing through the sewage discharge component and connected to the second anti-detachment ring 517.

[0052] The second anti-detachment ring 517 is threadedly connected to the bottom of the third slide bar 518.

[0053] The filter assembly includes a mounting ring 514 and a filter screen 516. The outer wall of the mounting ring 514 is slidably connected to the inner wall of the filter outer cylinder 51, and the inner wall of the mounting ring 514 is slidably connected to the outer wall of the filter screen 516. The filter screen 516 is slidably connected to the third slide rod 518 through a sliding hole. The mounting ring 514 is located below the pressure plate 513, and the top of the mounting ring 514 is in contact with the top of the support ring 515.

[0054] When the iron rod 510 is at the top, the top of the second anti-detachment ring 517 does not contact the bottom of the filter screen 516.

[0055] The first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter assembly 5 on one side of the inlet pipe 1 are inflow. The differential pressure monitoring component 3 monitors the real-time differential pressure and the real-time differential pressure change rate between the first inclined tube 54 and the second inclined tube 57. When the real-time differential pressure is greater than the cleaning threshold or the real-time differential pressure change rate is greater than the set value, the adjusting component 4 rotates to block the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter assembly 5 on one side of the inlet pipe 1. The sewage discharge component opens to discharge the water in the filter outer cylinder 51. The automatic air venting component 52 balances the air pressure in the filter outer cylinder 51 to normal pressure. When the pressure plate 513 moves downward, it moves in a normal pressure environment to avoid the water in the filter outer cylinder 51 generating upward resistance of the pressure plate 513, which helps to... The elastic potential energy of spring 511 is maximized and converted into the kinetic energy of pressure plate 513, activating electromagnet 59 of the impact assembly. Electromagnet 59 generates magnetism, attracting iron rod 510 to move upward. Iron rod 510 drives pressure plate 513 to move upward. Pressure plate 513 drives spring 511 to compress. Electromagnet 59 is de-energized, and the restoring force of spring 511 pushes pressure plate 513 downward. Pressure plate 513 moves downward until it contacts and impacts the mounting ring 514 of the filter assembly, generating an instantaneous impact force. The impact force is transmitted to filter screen 516, generating a local stress wave that peels off hard scale and adhering substances from the bottom of filter screen 516 of the filter assembly. The peeled hard scale and adhering substances fall into the sewage discharge assembly and are discharged by gravity.

[0056] When the self-cleaning filter assembly 5 on the other side of the inlet pipe 1 needs to be cleaned of scale and adhering substances, the adjusting component 4 is rotated to block the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter assembly 5 on the other side of the inlet pipe 1. The differential pressure monitoring component 3 continues to monitor the differential pressure between the first inclined tube 54 and the second inclined tube 57. When the differential pressure is greater than the cleaning threshold and the replacement threshold, the filter assembly of the self-cleaning filter assembly 5 on the inlet pipe 1 continues to filter. When the differential pressure is less than the replacement threshold, the filter assembly of the self-cleaning filter assembly 5 on the inlet pipe 1 needs to be replaced. This allows for accurate monitoring of the filtration performance of the filter assembly, which is beneficial for practical use.

[0057] Separate the second cover plate 53 of the impact component of the self-cleaning filter assembly 5 on one side of the water inlet pipe 1 from the filter outer cylinder 51. The second cover plate 53 drives the mounting rod 58 to move upward, the mounting rod 58 drives the mounting sleeve 512 to move upward, the pressure plate 513 drives the spring 511 to move upward, the spring 511 drives the pressure plate 513 to move upward, the pressure plate 513 drives the third slide rod 518 and the second anti-detachment ring 517 to move upward, the second anti-detachment ring 517 drives the filter screen 516 to move upward. After the filter screen 516 is taken out from the filter outer cylinder 51, separate the second anti-detachment ring 517 from the third slide rod 518, then remove the filter screen 516, and install a new filter screen 516 on the third slide rod 518. Then connect the second anti-detachment ring 517 to the third slide rod 518. Then send the filter screen 516 into the filter outer cylinder 51, and then connect the second cover plate 53 to the filter outer cylinder 51 for easy replacement of the filter screen 516.

[0058] The sewage discharge assembly includes a first control valve 55 and a sewage discharge pipe 56. The sewage discharge pipe 56 is fixedly installed at the bottom of the filter outer cylinder 51, and the first control valve 55 is fixedly installed on the sewage discharge pipe 56.

[0059] The first control valve 55 can be either a butterfly valve or a gate valve.

[0060] When sewage needs to be discharged, the first control valve 55 of the sewage discharge component is opened, and the scale, adhering substances or water in the outer filter cylinder 51 are discharged through the sewage discharge pipe 56.

[0061] The automatic exhaust assembly 52 includes a straight cylinder 5210, a sealing assembly, a venting assembly, and a floating propulsion assembly. The straight cylinder 5210 is fixedly connected to the top of the second cover plate 53. The venting assembly, the sealing assembly, and the floating propulsion assembly are fixedly installed on the inner wall of the straight cylinder 5210 from top to bottom. The upper and lower ends of the sealing assembly are respectively attached to the venting assembly and the floating propulsion assembly.

[0062] The ventilation assembly includes a top plate 524, which is fixedly installed on the upper end of the inner wall of the straight cylinder 5210. A conical hole 522 is provided at the center of the top plate 524, and the diameter of the lower end of the conical hole 522 is larger than the diameter of the upper end. The inner wall of the conical hole 522 is fitted and connected to the sealing assembly.

[0063] The sealing assembly includes a first slide rod 521, a conical plate 523, and a first horizontal plate 526. The first horizontal plate 526 is fixedly installed on the inner wall of the straight cylinder 5210. The first horizontal plate 526 is slidably connected to the first slide rod 521 through a sliding hole. The top of the first slide rod 521 is fixedly connected to the bottom of the conical plate 523. When the conical plate 523 is at its uppermost position, the outer wall of the conical plate 523 is slidably connected to the inner wall of the conical hole 522. The bottom of the first slide rod 521 is movably connected to the floating push assembly.

[0064] The floating propulsion assembly includes a first anti-detachment ring 525, a second horizontal plate 527, a float 528, and a second slide bar 529. The second horizontal plate 527 is fixedly installed on the inner wall of the straight cylinder 5210. The second horizontal plate 527 is slidably connected to the second slide bar 529 through a sliding hole. The top of the float 528 is fixedly connected to the bottom of the second slide bar 529. The upper end of the second slide bar 529 passes through the second horizontal plate 527 and is fixedly connected to the first anti-detachment ring 525. The top of the second slide bar 529 is movably connected to the bottom of the first slide bar 5210.

[0065] After the drain pipe 56 is opened, the water in the outer filter cylinder 51 is discharged. The float 528 of the floating push component of the automatic air venting component 52 does not come into contact with the water. The gravity of the float 528 drives the second slide rod 529 to move downward. The first anti-detachment ring 525 prevents the second slide rod 529 from detaching from the second horizontal plate 527. At the same time, the first slide rod 521 and the conical plate 523 move downward under the action of gravity. The conical plate 523 separates from the conical hole 522, which helps to discharge the water in the outer filter cylinder 51 and balance the air pressure in the outer filter cylinder 51 to normal pressure. When the pressure plate 513 moves downward, it moves in a normal pressure environment, which avoids the water in the outer filter cylinder 51 generating resistance to the upward movement of the pressure plate 513. This helps to maximize the conversion of the elastic potential energy of the spring 511 into the kinetic energy of the pressure plate 513.

[0066] When the water level in the outer filter cylinder 51 rises, the gas in the outer filter cylinder 51 is discharged through the gap between the conical plate 523 and the conical hole 522, preventing the gas in the outer filter cylinder 51 from entering the outlet pipe 2 through the first inclined pipe 54, thus reducing the possibility of water hammer. When the water level rises to contact the float ball 528, it pushes the float ball 528 to move upward. The float ball 528 drives the second sliding rod 529 to move upward. The second sliding rod 529 drives the first sliding rod 521 to move downward. The first sliding rod 521 drives the conical plate 523 to move upward. The conical plate 523 moves to contact the conical hole 522 and blocks the conical hole 522, thus preventing the water in the outer filter cylinder 51 from being discharged from the conical hole 522.

[0067] The ends of the first inclined tube 54 and the second inclined tube 57 near the outer filter cylinder 51 are higher than the ends of the first inclined tube 54 and the second inclined tube 57 near the water inlet pipe 1.

[0068] The ends of the first inclined tube 54 and the second inclined tube 57 near the outer filter cylinder 51 are higher than the ends of the first inclined tube 54 and the second inclined tube 57 near the inlet pipe 1. This helps the air in the first inclined tube 54 and the second inclined tube 57 to enter the outer filter cylinder 51 and then be discharged through the automatic exhaust assembly 52, preventing air from entering the inlet pipe 1 and the outlet pipe 2, and further reducing the possibility of water hammer.

[0069] Please refer to the instruction manual appendix. Figure 1 , Figure 4 and Figure 10The differential pressure monitoring component 3 includes a first water pressure sensor 31, a second water pressure sensor 32, and a controller 33. The first water pressure sensor 31 is fixedly installed on the side wall of the inlet pipe 1, and the second water pressure sensor 32 is fixedly installed on the side wall of the outlet pipe 2. Both the first water pressure sensor 31 and the second water pressure sensor 32 are communicatively connected to the controller 33. The controller 33 is also communicatively connected to the regulating component 4, the first control valve 55, and the electromagnet 59.

[0070] When the filter screen 516 is filtering, the first water pressure sensor 31 of the differential pressure monitoring component 3 monitors the water pressure in the inlet pipe 1, and the second water pressure sensor 32 monitors the water pressure in the outlet pipe 2. The real-time differential pressure value and the rate of change of the real-time differential pressure value between the first inclined tube 54 and the second inclined tube 57 are calculated by subtracting the water pressure value monitored by the second water pressure sensor 32 from the water pressure value monitored by the first water pressure sensor 31. When the real-time differential pressure value is greater than the cleaning threshold or the rate of change of the real-time differential pressure value is greater than the set value, the adjusting component 4 is rotated to block the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter component 5 on one side of the inlet pipe 1. The sewage discharge component is opened to discharge the water in the filter outer cylinder 51. The impact component is activated, and the impact component contacts the filter component to impact the filter component, generating an instantaneous impact force. The filter component generates a local stress wave, which peels off the hard scale and adhering substances at the bottom of the filter component. The peeled hard scale and adhering substances fall into the sewage discharge component and are discharged by gravity.

[0071] After cleaning the filter screen 516, the flow pump connected to the inlet pipe 1 controls the flow rate at the standard flow rate. The differential pressure monitoring component 3 continues to monitor the real-time differential pressure between the first inclined tube 54 and the second inclined tube 57 on one side of the inlet pipe 1. When the real-time differential pressure is greater than the initial differential pressure, the filter component of the self-cleaning filter component 5 on one side of the inlet pipe 1 continues to filter. When the real-time differential pressure is less than the initial differential pressure, the filter component of the self-cleaning filter component 5 on one side of the inlet pipe 1 needs to be replaced. This allows for accurate monitoring of the filtration performance of the filter component, which is beneficial for practical use.

[0072] Please refer to the instruction manual appendix. Figures 1-3 , Figures 4-5 The regulating component 4 includes a driving component, an assembly component, and a rotating sealing component. The two sets of rotating sealing components are respectively connected to the inlet pipe 1 and the outlet pipe 2. The two sets of rotating sealing components are connected to each other through the assembly component. The driving component is connected to one of the rotating sealing components and is connected to either the inlet pipe 1 or the outlet pipe 2.

[0073] The drive assembly includes a first gear ring 41, a support frame 46, a servo motor 47, and a second gear ring 48. The support frame 46 is fixedly connected to the outer wall of the inlet pipe 1 or the outlet pipe 2. The servo motor 47 is fixedly connected to the support frame 46.

The ends of the connecting shaft 42 that are far apart from each other are fixedly connected to the rotating disk 410. The rotating disk 410 is fixedly connected to the arc-shaped baffle 411. The arc-shaped baffles 411 of the two sets of rotary sealing assemblies are slidably connected to the inner walls of the inlet pipe 1 and the outlet pipe 2. The connecting shaft 42 of one set of rotary sealing assemblies is fixedly connected to the first gear ring 41. The adjacent ends of the connecting shafts 42 of the two sets of rotary sealing assemblies are connected by an assembly component.

[0075] The size of the arc-shaped baffle 411 is larger than the size of the connection between the second inclined tube 57 and the inlet pipe 1 and the size of the connection between the first inclined tube 54 and the outlet pipe 2;

[0076] The assembly includes a connecting rod 43 and a locking pin 44. The adjacent ends of the connecting shafts 42 of the two sets of rotating sealing assemblies are provided with grooves 49. The two ends of the connecting rod 43 are inserted into the two sets of grooves 49. The connecting shafts 42 of the two sets of rotating sealing assemblies are inserted into the locking pins 44 through sliding holes. The two sets of locking pins 44 are inserted into the two ends of the connecting rod 43.

[0077] The servo motor 47 of the drive component of the adjustment component 4 drives the second gear ring 48 to rotate, the second gear ring 48 drives the first gear ring 41 to rotate, the first gear ring 41 drives the connecting shaft 42 of a set of rotating sealing components to rotate, the connecting shaft 42 drives the connecting shaft 42 of another set of rotating sealing components to rotate through the connecting rod 43 and the locking pin 44, the connecting shaft 42 drives the rotating disk 410 to rotate, the rotating disk 410 drives the arc baffle 411 to rotate, the two sets of arc baffles 411 block the connection between the second inclined pipe 57 and the water inlet pipe 1 and the connection between the first inclined pipe 54 and the water outlet pipe 2, which facilitates simultaneous adjustment and is beneficial to practical use;

[0078] When a set of rotating plugging assemblies needs to be replaced or repaired, remove the locking pin 44 connected to the connecting shaft 42 of the rotating plugging assembly to be replaced or repaired. Then push the connecting rod 43 to rotate along the locking pin 44 connected to another set of rotating plugging assemblies. Then remove the rotating plugging assembly to be replaced or repaired, install the repaired rotating plugging assembly, and then install the removed locking pin 44. This facilitates the replacement of rotating plugging assemblies and ensures that the two sets of rotating plugging assemblies are driven in conjunction, which is beneficial for practical use.

[0079] Please refer to the instruction manual appendix. Figure 3 , Figure 6 and Figure 9The water inlet pipe 1 is also connected to a straight cylinder for flushing scale and adhering substances that adhere to the inner wall of the filter outer cylinder 51 after the filter screen 516 is cleaned. The flushing component 6 is connected to the controller 33.

[0080] The flushing assembly 6 includes a first pipe 61, a second pipe 62, a second control valve 63, and a straight pipe 64. The second pipe 62 is fixedly connected to the water inlet pipe 1 and to the input end of the second control valve 63. The two sets of first pipes 61 are fixedly connected to the two sets of output ends of the second control valve 63. The two sets of straight pipes 64 are fixedly connected to the two sets of first pipes 61 one by one. The straight pipes 64 are located inside the filter outer cylinder 51. The top of the straight pipes 64 is sealed. Spray holes 65 are evenly opened at the upper end of the straight pipes 64.

[0081] The straight tube 64 is positioned below the bottom of the third slide bar 518;

[0082] The second control valve 63 can be a T-type three-way valve or an L-type three-way valve;

[0083] After the filter screen 516 is cleaned of scale and adhering substances, the second control valve 63 opens the first pipe 61 in the direction of the cleaned filter screen 516. Water in the inlet pipe 1 enters the straight pipe 64 through the second pipe 62, the second control valve 63 and the first pipe 61, and is then sprayed into the filter outer cylinder 51 from the spray hole 65. The flowing water washes away the scale and adhering substances adhering to the inner wall of the filter outer cylinder 51. The water flow also drives the scale and adhering substances adhering to the inner wall of the filter outer cylinder 51 downward to the drain pipe 56, which helps to discharge the scale and adhering substances adhering to the inner wall of the filter outer cylinder 51 and is beneficial to actual use.

[0084] When the filter 516 is not cleaned, the second control valve 63 is not connected to any of the first pipes 61.

[0085] Example 2, please refer to the appendix of the instruction manual. Figure 1-9 A method for using a converter valve cooling water operation and maintenance equipment includes the following steps:

[0086] Step 1: Adjust component 4 to open the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter component 5 on the side of the water inlet pipe 1, so that the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter component 5 on the side of the water inlet pipe 1 can flow.

[0087] Step 2: The differential pressure monitoring component 3 monitors the real-time differential pressure and the rate of change of the real-time differential pressure between the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter component 5 on one side of the inlet pipe 1. When the real-time differential pressure is greater than the cleaning threshold or the rate of change of the real-time differential pressure is greater than the set value, the adjusting component 4 rotates to block the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter component 5 on one side of the inlet pipe 1. The drain component opens to drain the water in the outer filter cylinder 51. The impact component is activated, and the impact component contacts the filter component to impact the filter component, generating an instantaneous impact force. The filter component generates a local stress wave, which peels off the hard scale and adhering substances at the bottom of the filter component. The peeled hard scale and adhering substances fall into the drain component and are discharged by gravity. The first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter component 5 on the other side of the inlet pipe 1 are in the open state, and the filter component of the self-cleaning filter component 5 on the other side of the inlet pipe 1 performs normal filtration.

[0088] Step 3: The differential pressure monitoring component 3 monitors the real-time differential pressure and the rate of change of the real-time differential pressure between the first inclined tube 54 and the second inclined tube 57 of the self-cleaning filter component 5 on the other side of the inlet pipe 1. When the real-time differential pressure is greater than the cleaning threshold or the rate of change of the real-time differential pressure is greater than the set value, the filter component of the self-cleaning filter component 5 on the other side of the inlet pipe 1 cleans itself. The filter component of the self-cleaning filter component 5 on one side of the inlet pipe 1 is then activated again. The flow pump connected to the inlet pipe 1 controls the flow rate at the standard flow rate. The differential pressure monitoring component 3 continues to monitor the real-time differential pressure between the first inclined tube 54 and the second inclined tube 57 on one side of the inlet pipe 1. When the real-time differential pressure is greater than the initial differential pressure, the filter component of the self-cleaning filter component 5 on one side of the inlet pipe 1 continues to filter. When the real-time differential pressure is less than the initial differential pressure, the filter component of the self-cleaning filter component 5 on one side of the inlet pipe 1 needs to be replaced. This method can accurately grasp the filtration performance of the filter component and is beneficial for practical use.

[0089] After the filter assembly is cleaned, the regulating component 4 will guide the water into the cleaned filter assembly. The water flows through the cleaned filter, and the controller 33 monitors the instantaneous value of the real-time differential pressure during this process. If the real-time differential pressure value should drop rapidly and stabilize within a low value, it indicates that the filter assembly is cleaned well. If the real-time differential pressure value is still high or fluctuates greatly, it indicates that the cleaning is not thorough, and the self-cleaning filter assembly 5 is cleaned a second time.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
