Description

Technical Field

[0001] This invention relates to the field of condenser ball cleaning technology, and in particular to a ball collection device and method for a condenser ball cleaning system. Background Technology

[0002] As a key heat exchange device in the circulating cooling system of thermal power and nuclear power plants, the cleanliness of the heat transfer tube bundles of the condenser directly affects the unit's thermal efficiency and operating economy. Automatic ball cleaning systems are widely used for online cleaning of the inner walls of condenser tubes. These systems remove scale, microorganisms, and other contaminants by introducing soft balls that flow with the circulating water and using the balls' scrubbing action on the tube walls. In this system, the performance of the ball collection device is crucial; it is responsible for efficiently and reliably separating and recovering the cleaned balls from the cooling water for reuse.

[0003] Existing condenser ball cleaning and collection devices typically employ a filter screen structure. After the condenser balls enter the collector with the water flow, they are intercepted and collected by a collection screen installed in the pipeline, and then discharged for recycling through a dedicated pipeline. However, in actual operation, such devices often have the following problems and shortcomings: 1. Low ball collection efficiency and easy clogging: The mesh of traditional ball collection nets is easily clogged by debris in the water, broken rubber balls, or dirt accumulated on the net itself, which increases water flow resistance, reduces the ball collection flow area, seriously affects the normal circulation and recovery rate of rubber balls, and may even cause a large amount of rubber balls to be lost.

[0004] 2. Inconvenient maintenance and operational disruption: When the ball collecting net becomes clogged or requires maintenance, the system typically needs to be shut down or the corresponding valves closed to disassemble the ball collecting device from the pipeline for cleaning or replacement. This process is not only time-consuming and labor-intensive but also directly affects the continuous and stable operation of the unit or condenser.

[0005] 3. Passive or high-energy-consuming cleaning methods: Some designs use fixed filters and rely on reverse water flow for cleaning, which has limited cleaning effect and may interfere with the system's water flow; others are equipped with rotating cleaning components, but often require external electric or pneumatic drive devices, which increases system complexity, equipment cost and additional energy consumption.

[0006] 4. Insufficient structural design optimization: The flow channel design of some devices is unreasonable, with eddies or dead zones, which causes uneven distribution of the rubber balls in the ball collector, making them easy to accumulate and unable to be discharged smoothly, thus affecting the reliability of recycling.

[0007] 5. Adaptability needs improvement: It is not very adaptable to different water qualities, different ball characteristics, or different installation space conditions, and its versatility needs to be improved.

[0008] Therefore, developing a ball-collecting device that can automatically and continuously clean the ball-collecting net, prevent clogging, is easy to maintain, and can efficiently and reliably recover the balls while minimizing additional energy consumption is of great significance for improving the overall efficiency of the ball-collecting system, ensuring the long-term efficient operation of the condenser, and reducing power plant maintenance costs. This invention is proposed to solve the above-mentioned technical problems. Summary of the Invention

[0009] The purpose of this invention is to provide a ball collection device and method for a condenser ball cleaning system in order to solve the above-mentioned problems.

[0010] The present invention achieves the above objectives through the following technical solutions: On the one hand, the present invention provides a ball collection device for a condenser ball cleaning system, including a ball collection pipe, the upper and lower ends of which are used to connect to a circulating water pipe; A ball-collecting net, which is funnel-shaped, is fixedly installed inside the ball-collecting tube, and the upper diameter of the ball-collecting net is adapted to the inner diameter of the ball-collecting tube; A cleaning assembly includes a rotating shaft located at the center of the ball-collecting net and a scraper mounted on the rotating shaft and attached to the inner wall of the ball-collecting net. A drive mechanism, which is disposed inside or on the ball receiving tube, is used to drive the rotating shaft to rotate; A ball-ejecting net is installed at the lower end of the ball-receiving net, and a ball-ejecting tube is sealed to the side of the ball-ejecting net, extending to the outside of the ball-receiving tube.

[0011] Preferably, the diameter of the middle section of the ball receiving tube is larger than the diameter of its upper and lower end interfaces, and at least one of the upper and lower ends of the ball receiving tube has a tapered constriction structure.

[0012] Preferably, the diameter of the middle section of the ball receiving pipe is 0 to 0 times the diameter of the circulating water pipe.

[0013] Preferably, the ball outlet net is barrel-shaped, with a convection port on the side opposite to the ball outlet pipe that allows water to flow through, and the rest is a sealed surface.

[0014] Preferably, the scraper is a spiral scraper or a straight scraper.

[0015] Preferably, the driving mechanism is a hydraulic driving mechanism, which includes a drive shaft coaxially connected to the lower end of the rotating shaft and a spiral blade installed at the lower end of the drive shaft, wherein the rotation direction of the spiral blade matches the rotation direction of the scraper.

[0016] Preferably, the driving mechanism is an external power driving mechanism, which includes: The first support is fixedly installed below the ball-out net; The driven bevel gear is fixedly installed at the lower end of the rotating shaft; A drive shaft is rotatably inserted through the side wall of the ball receiving tube; The driving bevel gear is fixedly installed at the end of the drive shaft located inside the ball receiving tube and meshes with the driven bevel gear; The drive shaft is located at one end outside the ball receiving tube and is used to connect to an external power source.

[0017] Preferably, a support frame is installed inside the ball receiving tube at the position corresponding to the upper end of the rotating shaft, and the upper end of the rotating shaft is mounted on the support frame through a bearing seat; the lower end of the rotating shaft is rotatably connected to the ball outlet net or the first support seat through a bearing.

[0018] Preferably, a manhole is provided on the side wall of the ball receiving tube at the position corresponding to the ball outlet net or cleaning component, and a sealing cover is detachably provided on the manhole.

[0019] On the other hand, the present invention also provides a method for collecting condenser colloid balls in a condenser ball cleaning system, which uses the above-mentioned ball collection device and includes the following steps: The circulating water carries the rubber balls into the ball collection pipe; The ball is intercepted by the funnel-shaped ball-collecting net and guided to the ball-ejecting area at its lower end; The drive mechanism drives the rotating shaft and scraper to rotate, and the scraper continuously scrapes the inner wall of the ball collection net to prevent the mesh from clogging; The balls collected in the ball-ejection area are discharged and recycled through the ball-ejection tube.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the continuous operation of the cleaning components, impurities can be effectively prevented from adhering to and accumulating on the surface of the ball collection net, keeping the mesh unobstructed. This fundamentally solves the problem of easy clogging in traditional devices, thereby ensuring the ball recovery rate and the stability of system operation. 2. The drive mechanism offers two drive modes: hydraulic and external power. The hydraulic drive cleverly utilizes the system's own water flow energy, resulting in a simple structure and energy saving. The external power drive provides stable and reliable torque, making it suitable for working conditions with higher cleaning requirements and enhancing the adaptability of the device. 3. The independent maintenance pipe and sealing cover allow for the inspection, cleaning and maintenance of critical internal components without disassembling the main pipeline, greatly simplifying the maintenance process and reducing equipment downtime; 4. The enlarged diameter and streamlined design of the ball receiving tube reduces local flow velocity and resistance. Combined with the funnel-shaped ball receiving net and the ball exit net with convection outlet, it optimizes the collection and exit path of the rubber balls, improving ball receiving efficiency and reliability. 5. The overall structural design takes into account multiple objectives such as efficient ball collection, automatic cleaning, easy maintenance, and reliable operation, which helps to extend the overall service life of the condenser ball cleaning system, reduce operation and maintenance costs, and improve the economic efficiency of power plant operation.

Therefore, they should not be construed as limitations on this invention.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection", and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0033] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0034] like Figures 1-4 As shown, a ball collection device for a condenser ball cleaning system includes a ball collection pipe 2. The upper and lower ends of the ball collection pipe 2 are connected to existing circulating water pipes via flanges. The circulating water pipe above the ball collection pipe 2 is the upstream circulating water pipe 1, and the circulating water pipe below the ball collection pipe 2 is the downstream circulating water pipe 3. This connection method facilitates on-site installation and integration without affecting the existing piping system.

[0035] The diameter of the middle section of the ball receiving pipe 2 is 1.2 times the diameter of the circulating water pipe. Both the upper and lower ends of the ball receiving pipe 2 have tapered constriction structures, and the diameters of the upper and lower ends of the ball receiving pipe 2 are the same as the diameter of the circulating water pipe. The increased diameter of the middle section can reduce the water flow velocity in this area, which is conducive to the settling and collection of the rubber balls at the ball receiving net 23. The tapered constriction structure can achieve a smooth transition with the original circulating water pipe, reducing local resistance loss and turbulence.

[0036] A maintenance pipe 21 is installed on the side of the ball receiving pipe 2, corresponding to the ball net 24. The maintenance pipe 21 has a sealing cap 29. The maintenance pipe 21 facilitates the inspection, cleaning, or replacement of the internal ball receiving net 23, cleaning components, etc., without disassembling the main pipe, thus improving the maintainability of the device.

[0037] A funnel-shaped ball-collecting net 23 is fixedly installed inside the ball-collecting pipe 2. The upper diameter of the ball-collecting net 23 is adapted to the inner diameter of the ball-collecting pipe 2. A barrel-shaped ball-discharging net 24 is set at the lower end of the ball-collecting net 23. A ball-discharging pipe 22 is sealed on the side of the ball-discharging net 24 and extends out of the ball-collecting pipe 2. The funnel-shaped ball-collecting net 23 can effectively guide and collect the rubber balls that enter with the water flow, causing them to flow towards the central ball-discharging net 24 area. The barrel-shaped ball-discharging net 24, in conjunction with the side ball-discharging pipe 22, can discharge the collected rubber balls out of the system for easy recycling.

[0038] The ball-collecting net 23 is equipped with a cleaning component, which includes a rotating shaft 25 located at the center of the ball-collecting net 23, and a spiral scraper 26 mounted on the rotating shaft 25 and attached to the inner wall of the ball-collecting net 23. A support frame 211 is installed inside the ball-collecting tube 2 corresponding to the upper end of the rotating shaft 25, and the upper end of the rotating shaft 25 is mounted on the support frame 211 via a bearing seat 212. The lower end of the rotating shaft 25 extends below the ball-exit net 24, and the rotating shaft 25 is rotatably connected to the ball-exit net 24. During rotation, the spiral scraper 26 continuously scrapes the inner wall of the ball-collecting net 23 to prevent dirt, impurities, or rubber balls from clogging the mesh, ensuring the filtration efficiency and flow capacity of the ball-collecting net 23. The upper and lower support structures ensure the stable rotation of the rotating shaft 25.

[0039] The lower part of the ball receiving tube 2 is equipped with a drive mechanism for rotating the rotating shaft 25.

[0040] The drive mechanism includes a drive shaft 27, a spiral blade 28, and a connecting rod 213. The upper end of the drive shaft 27 is coaxially and fixedly connected to the lower end of the rotating shaft 25. The spiral blade 28 is mounted on the lower end of the drive shaft 27 via the connecting rod 213. The spiral direction of the spiral blade 28 is the same as that of the spiral scraper 26. This drive mechanism cleverly utilizes the kinetic energy of the circulating water to drive the spiral blade 28 to rotate, which in turn drives the rotating shaft 25 and the spiral scraper 26 to rotate via the drive shaft 27. No additional electricity or power source is required, achieving energy-saving and adaptive cleaning drive. The consistent spiral direction ensures coordinated scraping and propulsion directions.

[0041] In addition, this embodiment also discloses a method for collecting condenser colloid cleaning balls, including the following steps: S1. The circulating water carries the rubber balls that have completed the cleaning cycle from the upstream circulating water pipe 1 into the ball collection pipe 2; S2. The water flows through the buffer zone formed by the expansion of the inner diameter of the ball collection pipe 2, and the flow velocity decreases. The rubber ball enters and contacts the funnel-shaped ball collection net 23 under the influence of gravity and water flow. S3. The ball is intercepted by the ball-collecting net 23 and gathers downward along its inner wall, eventually being guided into the barrel-shaped ball-ejecting net 24 area located at the lower end of the ball-collecting net 23. S4. During the ball collection process or within a set period, the drive mechanism starts to work, driving the rotating shaft 25 located at the center of the ball collection net 23 to rotate, causing the scraper mounted on the rotating shaft 25 to rotate accordingly. S5. The rotating scraper continuously scrapes the inner wall of the ball collection net 23 to remove impurities, dirt or potentially stuck rubber balls attached to the mesh, keeping the filter surface of the ball collection net 23 clean and the mesh unobstructed. S6. The balls collected in the ball-ejection net 24 are discharged from the ball-collecting device and enter the recycling pipeline through the ball-ejection pipe 22, which is sealed and connected to the side of the ball-ejection net 24, under the subsequent water flow or by their own weight. S7. When it is necessary to inspect, maintain or clean the inside of the device, the sealing cover 29 of the maintenance pipe 21 located on the side wall of the receiving pipe 2 can be opened to carry out the operation without disassembling the main pipe.

[0042] Furthermore, the driving mechanism is a hydraulic driving mechanism. Step S4 specifically involves the water flow driving the spiral blade 28 installed at the lower end of the driving shaft 27 to rotate, thereby driving the rotating shaft 25 and the scraper to rotate synchronously through the driving shaft 27. Example 2

[0043] like Figures 5-8 As shown, the difference between this embodiment and Embodiment 1 is that: The diameter of the middle section of the ball receiving pipe 2 is 1.2 times the diameter of the circulating water pipe. The lower end of the ball receiving pipe 2 has a tapered constriction structure and the upper end has a straight constriction structure. The diameters of the upper and lower ends of the ball receiving pipe 2 are the same as the diameter of the circulating water pipe. The straight constriction structure at the upper end is more adaptable in some situations where installation space is limited, while the tapered constriction at the lower end still ensures a smooth transition downstream.

[0044] The scraper is a straight scraper 210; the straight scraper 210 has a simple structure and low manufacturing cost, and is suitable for working conditions where dirt adhesion is not serious or where greater scraping force is required.

[0045] The drive mechanism includes a drive shaft 27, a connecting rod 213, a first support 214, a driven bevel gear 215, a driving bevel gear 216, a second support 217, and a mounting flange 218. The first support 214 is fixedly installed at the lower end of the ball outlet net 24. The first support 214 is L-shaped. The driven bevel gear 215 is fixedly installed below the first support 214 at the lower end of the rotating shaft 25. The drive shaft 27 is inserted into the side of the first support 214. The driving bevel gear 216, which meshes with the driven bevel gear 215, is fixedly installed at the end of the drive shaft 27 near the driven bevel gear 215. The end of the drive shaft 27 away from the driving bevel gear 216 extends to the outside of the ball collection tube 2. The second support 217 is installed on the ball collection tube 2 at the position corresponding to the drive shaft 27. The drive shaft 27 passes through the second support 217 and exits the ball collection tube 2 to be connected to the output shaft of the external drive motor. This gear-driven drive mechanism is powered by an external motor, providing high driving torque and controllable speed. It is suitable for applications requiring higher cleaning intensity and frequency, or where water flow power is insufficient. The bevel gear transmission enables the conversion of power direction and has a compact structure.

[0046] The rotating shaft 25 is connected to the first support seat 214 through the first bearing assembly, the drive shaft 27 is connected to the first support seat 214 through the second bearing assembly, and the drive shaft 27 is connected to the second support seat 217 through the third bearing assembly.

[0047] The first bearing assembly includes a first bearing sleeve fixedly embedded in a first support seat 214, a first bearing installed inside the first bearing sleeve, a first bearing cover fixedly mounted on the first bearing sleeve, an O-ring seal installed on the contact surface between the first bearing cover and the first bearing sleeve, and Y-ring seals installed between the first bearing sleeve and the rotating shaft 25, and between the first bearing cover and the rotating shaft 25, to ensure the sealing of the bearing inside the first bearing sleeve; the first bearing assembly and the second bearing assembly have the same structure. The multi-layer sealing design (O-rings and Y-rings) effectively prevents circulating water from seeping into the bearing, avoiding lubrication failure and bearing corrosion, and greatly extending the service life and reliability of the transmission components in the underwater environment.

[0048] The third bearing assembly includes a second bearing sleeve fixedly embedded in the second support seat 217. A second bearing is installed inside the second bearing sleeve. A second bearing cover is fixedly mounted on the second bearing sleeve. An O-ring is installed on the contact surface between the second bearing cover and the second bearing sleeve. Y-rings are installed between the second bearing sleeve and the drive shaft 27, and between the second bearing cover and the drive shaft 27, to ensure the sealing of the bearing inside the second bearing sleeve and simultaneously achieve sealing of the ball receiving tube 2 at the ball exit tube 22. This bearing assembly both supports the drive shaft 27 and ensures a dynamic seal where the drive shaft 27 exits the ball receiving tube 2, preventing system leakage. Example 3

[0049] Based on Embodiment 1, this embodiment further includes a mesh-like convection port on the side of the ball outlet net 24 opposite to the ball outlet pipe 22, and a sealing surface outside the convection port on the side of the ball outlet net 24. The convection port allows some water flow to pass laterally through the ball outlet net 24, creating turbulence inside the net. This helps prevent the balls from accumulating or sticking at the bottom of the net, promoting smoother entry of the balls into the ball outlet pipe 22 and improving ball collection efficiency and reliability. The sealing of the non-convection area ensures that most of the balls are guided to the ball outlet pipe 22.

[0050] The foregoing has shown and described 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 to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed.
