Description

Technical Field

[0001] The present invention belongs to the technical field of geothermal energy heating, and specifically relates to a pipeline filtering device for geothermal energy heating operation. Background Technique

[0002] A geothermal energy heating system refers to the process of transmitting geothermal energy from underground to the ground through pipelines for heating. During this process, it is necessary to ensure the cleanliness of the fluid inside the pipeline to maintain the efficient operation of the system. The types of impurities that may be contained in the fluid include: sediment particles; corrosion products; other suspended solids. These impurities are usually gradually generated and accumulated by the internal environment of the geothermal well or after long-term use of the pipeline. If not removed in time, it will have a certain impact on the normal operation of the heating system. Currently, geothermal energy heating pipelines usually have filtering devices installed at key positions to intercept solid particles in the fluid, but such devices have certain limitations in actual applications.

[0003] During the operation of the existing pipeline filtering device, although it can intercept some impurities in the fluid, due to the large differences in the size and shape of the impurities in the fluid, the filtering device is prone to clogging. Especially after long-term operation, the interception efficiency of the filtering device will decline, resulting in some impurities passing through and entering the subsequent pipeline, thereby having an adverse impact on the performance of the heating equipment. In addition, when cleaning and maintaining the existing filtering device, it is often necessary to interrupt the operation of the heating system, which to a certain extent reduces the overall efficiency of heating operation. For this reason, the present invention provides a pipeline filtering device for geothermal energy heating operation. Summary of the Invention

[0013] The beneficial effects of the present invention are as follows: 1. A pipeline filtering device for geothermal energy heating operation according to the present invention. Through this design, when the fluid flows rapidly on the surface of the filter cylinder, the high-speed flowing fluid will impact the turntable. After being impacted by the fluid, the turntable will drive two diversion sleeves to rotate. When the diversion sleeves rotate, the sliders on the elastic rods will slide back and forth inside the spiral grooves opened on the surface. When the elastic rods slide, they will push the cleaning rings to slide back and forth. When the through grooves are pushed by the elastic rods and slide reciprocally on the surface of the filter cylinder, the sliding cleaning rings will slide back and forth on the surfaces of multiple first flow holes and second flow holes. At the same time, when the elastic rods slide, the sliding of the elastic rods will drive the rollers to rotate. When the rollers rotate, they will drive the cleaning ring two to slide back and forth through the push plate when the elastic rods and the cleaning rings slide. At this time, when the cleaning rings slide back and forth, it can reduce the blockage of the fluid when passing through the first flow holes and the second flow holes into the filter cylinder due to the large particles in the fluid, which will affect the flow of the fluid into the filter cylinder, resulting in the abnormal generation or transmission of the signal of the flow dividing plate. Furthermore, it can ensure that the fluid pulse signal can be smoothly transmitted to the ground, thereby improving the accuracy and reliability of the measurement data; 2. A pipeline filtering device for geothermal energy heating operation according to the present invention. Through this design, when the elastic rod drives the cleaning ring to slide, the sliding of the elastic rod will drive the roller to slide through the connecting arm. When the roller slides, it will rotate due to the friction force with the surface of the filter cylinder. When the roller rotates, it will drive the push plate to make an eccentric rotation back and forth through the eccentric shaft. When the push plate is subjected to the eccentric rotation of the eccentric shaft, it will drive the cleaning ring two to slide back and forth. When the push plate pushes the cleaning ring two to slide towards the cleaning ring, the sliding of the cleaning ring two can scrape and clean the surface of the filter cylinder and the first flow holes and the second flow holes again. At the same time, when the cleaning ring two slides back and forth, the sliding of the cleaning ring two will also slide in the fluid. At this time, the fluid will scour the surface of the cleaning ring two when the cleaning ring two slides. Thus, through the scouring of the fluid on the cleaning ring two, it can reduce the situation that the impurities to be cleaned adhere to the surface of the cleaning ring two when sliding and cleaning the surface of the filter cylinder, and reduce the accumulation of impurities on the cleaning ring two due to the adhesion of impurities, which will affect the cleaning effect when the cleaning ring two slides; 3. In the pipeline filtering device for geothermal energy heating operation according to the present invention, through this design, when the push plate is subjected to the eccentric rotation of the roller and the eccentric shaft, the push plate will perform eccentric rotation and slide back and forth at the same time. When the push plate rotates to the upper dead center of the roller, the teeth on the push plate will exert an upward extrusion on the U-shaped frame. When the U-shaped frame is subjected to the upward extrusion of the push plate, the U-shaped frame will drive the flexible plate to elastically bend inside the U-shaped frame. At this time, the flexible plate will block the bottom of the U-shaped frame at the bottom of the U-shaped frame. At the same time, when the push plate slides due to the eccentric rotation of the eccentric shaft, the sliding of the push plate will drive the U-shaped frame to slide inside the rectangular groove through the teeth. When the U-shaped frame slides, it will drive the moving plate three to extrude the fluid between the flexible plate and the U-shaped frame. After the fluid is extruded, it will enter the inside of the cleaning ring through the conveying pipe. At the same time, when the cleaning ring two slides back and forth due to the sliding of the push plate, the sliding of the cleaning ring two will extrude the flowing fluid. At this time, the fluid extruded by the cleaning ring two will enter the cleaning ring through the through groove and the fluid entering the inside of the cleaning ring through the conveying pipe will impact the first flow hole and the second flow hole through multiple spray holes on the side wall of the cleaning ring, thereby reducing the situation that the fluid flow is affected when the cleaning ring slides to clean the fluid impurities on the first flow hole and the second flow hole when the fluid passes through the first flow hole and the second flow hole and enters the inside of the filter cartridge, and reducing the situation that the flow rate of the fluid entering the inside of the filter cartridge is unstable due to the sliding of the cleaning ring, thereby affecting the flow rate pressure value of the fluid entering the inside of the filter cartridge and causing the detection signal to deviate and be unstable.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figures 1-7 As shown, a pipeline filtering device for geothermal heating operation described in an embodiment of the present invention includes a filter cartridge 1, a diverter plate 2, a rotating mechanism and a sliding mechanism. The filter cartridge 1 is a cylindrical structure, and a diverter plate 2 is fixedly connected to its left inner wall. The outer surface of the diverter plate 2 is provided with a plurality of first flow holes 3 and second flow holes 4. The first flow holes 3 are distributed in a circular array, while the second flow holes 4 are distributed in a circular array with the diverter plate 2 as the center. The function of the diverter plate 2 is to preliminarily divert the fluid entering the filter cartridge 1 so that it can evenly pass through the first flow holes 3 and the second flow holes 4 into the interior of the filter cartridge 1. Several support rods 5 are fixedly connected to the outer surface of the filter cartridge 1. These support rods 5 are used to reinforce the overall structure of the filter cartridge 1 and provide support points for the installation of subsequent components. A drive shaft 6 is also fixedly connected to the interior of the filter cartridge 1, and an adjustment plate 7 is fixedly connected to one end of the drive shaft 6. The adjustment plate 7 is slidably connected to the interior of the filter cartridge 1. The sliding connection between the adjustment plate 7 and the filter cartridge 1 ensures that the adjustment plate 7 can be positioned inside the filter cartridge 1 to adapt to fluid requirements of different flow rates.

[0019] like Figures 1-7 As shown, the rotating mechanism is one of the important components of this device, which is mainly composed of a turntable 8, a guide sleeve 9, a limit sleeve 11 and a guide cylinder 12. The turntable 8 is rotatably connected to the outer surface of the filter cartridge 1. The left and right sides of the turntable 8 are fixedly connected to the guide sleeve 9, and the outer surface of the guide sleeve 9 is provided with a spiral groove 10. When the fluid flows through the filter cartridge 1 rapidly, the high-speed flow of the fluid will generate an impact force on the turntable 8, so that the turntable 8 drives the guide sleeve 9 to rotate. The limit sleeve 11 is arranged on the side of the turntable 8 close to the support rod 5, and the side of the limit sleeve 11 away from the turntable 8 is fixedly connected to a number of guide cylinders 12. The guide cylinder 12 is used to guide the elastic rod 13 in the sliding mechanism to perform linear motion. The rotational connection relationship between the limit sleeve 11 and the turntable 8 ensures that the turntable 8 can rotate freely when impacted by the fluid without being stuck due to external resistance.

[0020] As shown Figures 1-7 in the figure, the main function of the sliding mechanism is to clean the impurities in the fluid. It includes an elastic rod 13, a slider 14, a cleaning ring 15 and a through groove 16. The elastic rod 13 is fixedly connected to the inner wall of the guide cylinder 12 on the side close to the limit sleeve 11. One side of the elastic rod 13 close to the diversion sleeve 9 is fixedly connected with a slider 14. The end of the slider 14 away from the elastic rod 13 is slidably connected to the inside of the spiral groove 10 on the outer surface of the diversion sleeve 9. When the diversion sleeve 9 rotates under the impact of the fluid, the spiral groove 10 will apply a thrust along the spiral direction to the slider 14, so that the slider 14 drives the elastic rod 13 to slide reciprocally. The other end of the elastic rod 13 is fixedly connected with a cleaning ring 15. A plurality of through grooves 16 are formed in the side wall of the cleaning ring 15. The inside of the cleaning ring 15 is a hollow structure, and a plurality of spray holes 17 are also formed in its side wall. The through grooves 16 are communicated with the inside of the cleaning ring 15, so that the fluid can enter the inside of the cleaning ring 15 through the through grooves 16 and be sprayed out through the spray holes 17. The reciprocating sliding of the cleaning ring 15 can scrape the surfaces of the first flow hole 3 and the second flow hole 4, so as to remove the impurities attached to the surface of the hole.

[0021] As shown Figures 1-7 in the figure, in order to further improve the cleaning effect, an auxiliary component is also provided on the outer surface of the elastic rod 13. The auxiliary component includes two connecting arms 18, a roller 19, an eccentric shaft 20 and a push plate 21. The two connecting arms 18 are fixedly connected to the outer surface of the elastic rod 13 and are symmetrically distributed with the elastic rod 13 as the center. A roller 19 is rotatably connected to the end of each connecting arm 18 away from the elastic rod 13. An eccentric shaft 20 is fixedly connected between the two rollers 19. The eccentric shaft 20 is eccentrically arranged with the roller 19. A push plate 21 is rotatably connected to the outer surface of the eccentric shaft 20. One end of the push plate 21 close to the cleaning ring 15 is rotatably connected with a second cleaning ring 22. The second cleaning ring 22 is slidably connected to the outer surfaces of a plurality of elastic rods 13. When the elastic rod 13 drives the cleaning ring 15 to slide, the movement of the elastic rod 13 will drive the roller 19 to rotate through the connecting arm 18. The rotation of the roller 19 will drive the push plate 21 to rotate eccentrically through the eccentric shaft 20. The eccentric rotation of the push plate 21 will push the second cleaning ring 22 to slide back and forth on the outer surface of the elastic rod 13. The sliding of the second cleaning ring 22 can perform secondary scraping on the surface of the filter cartridge 1 and the first flow hole 3 and the second flow hole 4, so as to further remove the remaining impurities.

[0022] As shown Figures 1-7As shown, a fixing component is further provided on the outer surface of the cleaning ring 15. The fixing component includes a plurality of U-shaped frames 23, a flexible plate 24, and a delivery pipe 26. The U-shaped frame 23 is fixedly connected to the side of the limit sleeve 11 away from the turntable 8. The end of the U-shaped frame 23 away from the turntable 8 is fixedly connected to the support rod 5. The U-shaped frame 23 is slidably connected to the outer surface of the cleaning ring 15. A plurality of through holes II are formed in the top of the U-shaped frame 23. A flexible plate 24 is fixedly connected to the inner wall of the side of the U-shaped frame 23 close to the support rod 5. A rectangular groove 25 is formed in the side wall of the flexible plate 24. The delivery pipe 26 is fixedly connected to the bottom of the U-shaped frame 23. The end of the delivery pipe 26 away from the U-shaped frame 23 communicates with the inside of the cleaning ring 15. When the cleaning ring 15 slides driven by the elastic rod 13, the cleaning ring 15 will exert a squeezing effect on the fluid. The squeezed fluid will enter the inside of the cleaning ring 15 through the through groove 16 and enter the cavity between the flexible plate 24 and the U-shaped frame 23 through the delivery pipe 26.

[0023] As Figures 1-7 shown, in order to further optimize the fluid flow and cleaning effect, a compression component is further provided inside the U-shaped frame 23. The compression component includes a compression spring 27, a U-shaped frame 28, and a moving plate III 29. The compression spring 27 is fixedly connected to the inner wall of the rectangular groove 25 on the side close to the delivery pipe 26. The end of the compression spring 27 away from the delivery pipe 26 is fixedly connected to the U-shaped frame 28. The U-shaped frame 28 is slidably connected to the inside of the rectangular groove 25. A moving plate III 29 is fixedly connected to the side of the U-shaped frame 28 close to the delivery pipe 26. The moving plate III 29 is slidably connected to the top outer wall of the flexible plate 24. When the push plate 21 is subjected to the eccentric rotation of the eccentric shaft 20, the push plate 21 will push the U-shaped frame 28 to slide inside the rectangular groove 25. The sliding of the U-shaped frame 28 will drive the moving plate III 29 to squeeze the fluid between the flexible plate 24 and the U-shaped frame 23. The squeezed fluid will enter the inside of the cleaning ring 15 through the delivery pipe 26 and be ejected through the spray holes 17, so as to perform high-pressure flushing on the first flow holes 3 and the second flow holes 4.

[0024] In practical applications, when the fluid in the geothermal energy heating system passes through the filter cartridge 1, the fluid will first enter the interior of the filter cartridge 1 through the first flow holes 3 and the second flow holes 4 on the flow distribution plate 2. Due to the impact force generated by the high-speed flow of the fluid on the rotating disc 8, the rotating disc 8 will drive the guide sleeve 9 to rotate. The rotation of the guide sleeve 9 will push the slider 14 to slide reciprocally through the spiral groove 10, and the movement of the slider 14 will further drive the elastic rod 13 and the cleaning ring 15 to slide reciprocally. The sliding of the cleaning ring 15 will scrape the surfaces of the first flow holes 3 and the second flow holes 4, thereby removing the impurities adhering to the surface of the hole channels. At the same time, the movement of the elastic rod 13 will drive the second cleaning ring 22 to perform secondary scraping through the auxiliary component, further improving the cleaning effect. In addition, the sliding of the cleaning ring 15 and the second cleaning ring 22 will also exert a squeezing effect on the fluid. The squeezed fluid will enter the interior of the cleaning ring 15 through the conveying pipe 26 and be ejected through the spray holes 17, thereby performing high-pressure flushing on the first flow holes 3 and the second flow holes 4 to ensure that the fluid can smoothly pass through the hole channels and enter the interior of the filter cartridge 1.

[0025] Through the above structure and operating principle, the device of the present invention can effectively clean the impurities in the fluid of the geothermal energy heating system, avoid the problem of fluid flow obstruction caused by impurity blockage, and thus ensure the normal operation of the system and the accuracy of the measurement data.

[0026] In order to better enable the relevant personnel in the technical field to fully understand and implement the present invention, the following supplements the specific implementation principle of the present invention in combination with a specific application scenario.

[0027] First of all, when the fluid of the geothermal energy heating system enters the filter cartridge 1, the fluid will pass through the first flow holes 3 and the second flow holes 4 on the flow distribution plate 2. The design of the flow distribution plate 2 enables the fluid to be evenly distributed, avoiding the problem of uneven impact force caused by too fast local flow velocity. The annular array distribution of the first flow holes 3 and the second flow holes 4 further ensures the uniformity of the fluid when entering the interior of the filter cartridge 1. During this process, the high-speed flowing fluid generates an impact force on the rotating disc 8, and the rotating disc 8 drives the guide sleeve 9 to rotate through its fixed connection with the guide sleeve 9. The spiral groove 10 on the outer surface of the guide sleeve 9 exerts a thrust on the slider 14 during rotation, and the slider 14 moves reciprocally along the trajectory of the spiral groove 10. Since the slider 14 is fixedly connected to the elastic rod 13, the movement of the slider 14 will be converted into a linear reciprocating movement of the elastic rod 13, and then drive the cleaning ring 15 to slide reciprocally on the inner wall of the filter cartridge 1.

[0028] Secondly, the sliding of the cleaning ring 15 realizes the scraping operation on the surfaces of the first flow hole 3 and the second flow hole 4. When the cleaning ring 15 slides on the inner wall of the filter cartridge 1, the through groove 16 formed on its side wall will exert a certain squeezing effect on the fluid. The squeezed fluid will enter the inner cavity of the cleaning ring 15 through the through groove 16 and be ejected through the spray holes 17. This process not only removes the impurities attached to the surface of the pore channel, but also performs a secondary cleaning of the pore channel by means of high-pressure spraying, ensuring that the fluid can smoothly pass through the pore channel and enter the interior of the filter cartridge 1. In addition, the sliding of the cleaning ring 15 also scrapes the inner wall of the filter cartridge 1, further reducing the accumulation of impurities.

[0029] Meanwhile, the movement of the elastic rod 13 drives the second cleaning ring 22 to perform a secondary scraping through the auxiliary component. Specifically, the reciprocating movement of the elastic rod 13 is transmitted to the roller 19 through the connecting arm 18. During the rotation of the roller 19, the eccentric shaft 20 drives the push plate 21 to perform eccentric rotation. The eccentric rotation of the push plate 21 pushes the second cleaning ring 22 to slide back and forth on the outer surface of the elastic rod 13. The sliding of the second cleaning ring 22 not only performs a secondary scraping on the inner wall of the filter cartridge 1 and the first flow hole 3 and the second flow hole 4, but also generates a disturbing effect on the fluid during the sliding process. This disturbing effect makes it more difficult for the suspended impurities in the fluid to reattach to the surface of the second cleaning ring 22, thus avoiding the problem of the cleaning effect degradation of the second cleaning ring 22 due to the accumulation of impurities.

[0030] Furthermore, the sliding of the cleaning ring 15 and the second cleaning ring 22 will also exert a squeezing effect on the fluid between the flexible plate 24 and the U-shaped frame 23. When the cleaning ring 15 slides, the relative movement between its outer surface and the U-shaped frame 23 will compress the cavity between the flexible plate 24 and the U-shaped frame 23. The compressed fluid will enter the interior of the cleaning ring 15 through the delivery pipe 26 and be ejected through the spray holes 17 to perform a high-pressure flushing on the first flow hole 3 and the second flow hole 4. This design makes full use of the dynamic characteristics of the fluid, converts the movement of the fluid into cleaning power, avoids the introduction of an additional power source, and thus improves the overall efficiency of the device.

[0031] Finally, the design of the compression component further optimizes the fluid flow effect. When the push plate 21 is subjected to the eccentric rotation of the eccentric shaft 20, the push plate 21 will push the U-shaped frame 28 to slide inside the rectangular groove 25. The sliding of the U-shaped frame 28 drives the third moving plate 29 to squeeze the fluid between the flexible plate 24 and the U-shaped frame 23. The squeezed fluid will enter the interior of the cleaning ring 15 through the delivery pipe 26 and be ejected through the spray holes 17. This process not only improves the fluidity of the fluid, but also further cleans the first flow hole 3 and the second flow hole 4 by means of high-pressure spraying, ensuring that the fluid can enter the interior of the filter cartridge 1 at a stable speed and pressure.

[0032] Through the above steps and operating principles, the device of the present invention can achieve efficient cleaning of fluid impurities in the geothermal energy heating system. The synergistic effect of the cleaning ring 15 and the second cleaning ring 22 ensures the thorough removal of impurities, while the design of the flexible plate 24, the U-shaped frame 23 and the compression assembly further optimizes the fluid flow effect, avoiding measurement data deviation problems caused by impurity blockage or fluid instability. The entire device can complete cleaning and maintenance without interrupting the operation of the heating system, significantly improving the operating efficiency and reliability of the geothermal energy heating system.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
