Description

Technical Field

[0001] The utility model relates to the technical field of online cleaning of heat exchange equipment, in particular to a horizontal rubber ball cleaning device for a pipe end, and heat exchange equipment comprising the horizontal rubber ball cleaning device for a pipe end. Background Art

[0002] Some heat exchange equipment (such as the condenser of a central air conditioner) has multiple heat exchange tubes, and cooling water circulates inside to exchange heat with a heat medium. After running for a period of time, sludge, dissolved salts, etc. in the cooling water will be deposited on the inner wall of the heat exchange tube, resulting in a decrease in heat exchange efficiency. For this reason, a rubber ball cleaning device is used in the art to perform online cleaning of the heat exchange tube. This rubber ball cleaning device has an inlet pipe and an outlet pipe, and a ball sending and receiving mechanism connected to the inlet pipe and the outlet pipe. The ball sending and receiving mechanism is used to send a rubber ball to the inlet pipe, and the rubber ball enters the heat exchange tube with the inlet water. As the rubber ball squeezes and scrubs the inner wall of the heat exchange tube, the sediment on the inner wall of the heat exchange tube is removed, and then the rubber ball leaves the heat exchange tube with the outlet water and is recovered by the ball sending and receiving device at the outlet pipe.

[0003] There are many problems with existing rubber ball cleaning devices. Some rubber ball cleaning devices have water inlet and outlet pipes arranged vertically in parallel to adapt to heat exchange equipment with water inlet and outlet pipes arranged vertically in parallel, but this type of rubber ball cleaning device cannot adapt to heat exchange equipment with water inlet and outlet pipes arranged horizontally in parallel. Some rubber ball cleaning devices use an inner and outer cylinder structure. As the operating time increases, rust or sludge in the water system will be deposited between the inner and outer cylinders, causing the inner cylinder rotation torque to increase, and even causing the inner cylinder to get stuck and unable to rotate. Since the inner and outer cylinders mostly use compression seals, the sealing phenomenon will also appear after long-term use, which is particularly obvious in high-pressure areas, making it inconvenient to take / put the ball. There are also some rubber ball cleaning devices whose center distance between the water inlet and outlet pipes cannot be adjusted, which greatly limits the flexibility of on-site installation.

[0004] In order to at least overcome the above problems in the prior art, the utility model aims to provide a horizontal rubber ball cleaning device for pipe ends with a stable and reliable structure, and to provide a heat exchange device with improved performance. Utility Model Content

[0005] In the first aspect of the utility model, a horizontal rubber ball cleaning device for pipe ends is provided, comprising: an inlet pipe, a water inlet and a ball outlet are provided on its side wall; an outlet pipe is arranged horizontally and parallel to the inlet pipe, and a ball receiving port and a water outlet are provided on its side wall; an upper ball storage chamber is surrounded by a first cylindrical wall, the first cylindrical wall is connected to the outlet pipe through the ball receiving pipe, and the first cylindrical wall is located on the upper side of the outlet pipe; a middle ball storage chamber is surrounded by the upper part of a second cylindrical wall, the second cylindrical wall is arranged vertically to the first cylindrical wall, and a ball receiving port is provided on the upper part of the second cylindrical wall. A window for replacing the rubber ball, the second cylindrical wall is located between the water inlet pipe and the water outlet pipe; the lower ball storage chamber is surrounded by the lower part of the second cylindrical wall, and the lower part of the second cylindrical wall is provided with a first port and a second port, the first port is connected to the water intake port through a water intake pipe, and the second port is connected to the ball serving port through a ball serving pipe; the first valve is sandwiched between the first cylindrical wall and the second cylindrical wall, and is used to connect or cut off the communication between the upper ball storage chamber and the middle ball storage chamber; the second valve is located in the middle part of the second cylindrical wall, and is used to connect or cut off the communication between the middle ball storage chamber and the lower ball storage chamber.

[0006] According to the scheme, the outlet pipe and the inlet pipe of the rubber ball cleaning device are arranged horizontally in parallel, so that the device can be adapted for use on heat exchange equipment with the inlet and outlet pipes arranged horizontally in parallel, and the sediment on the inner wall of the pipe of such heat exchange equipment can be cleaned; wherein the second cylindrical wall is arranged vertically with the first cylindrical wall, and the inner and outer cylinder structure is not adopted, so as to avoid the deposition of rust or sludge and hinder the use of the equipment, and ensure the normal operation of the system; when the first valve and the second valve are closed, the upper, middle and lower ball storage chambers are not connected, the system does not work, the rubber balls are stored in the middle ball storage chamber, and the ball taking / putting operation can be performed; when the first valve is closed and the second valve is opened, The rubber ball falls into the lower ball storage chamber, and the water in the water inlet pipe enters the lower ball storage chamber through the water intake pipe, flushing the rubber ball along the ball serving pipe and entering the water inlet pipe to achieve ball serving; after the rubber ball comes out from the outlet pipe of the heat exchanger, it flows through the ball receiving pipe into the upper ball storage chamber with the water flow. After the ball and water are separated, the rubber ball is temporarily stored in the upper ball storage chamber, and the water flows into the outlet pipe from the water outlet of the upper ball storage chamber to complete the ball receiving process; after the ball serving and receiving are completed, the second valve is closed and the first valve is opened, and the rubber ball flows from the upper ball storage chamber into the middle ball storage chamber with the water flow. After all the rubber balls enter the middle ball storage chamber, the first valve is closed and the system waits for the next ball serving and receiving, thereby achieving stable operation.

[0007] In some embodiments, the first valve includes a first valve plate and a first rotating shaft, and the first rotating shaft is driven to rotate by a first driving motor, and the rotating shaft is substantially perpendicular to the center line of the first cylindrical wall.

[0008] According to the scheme, in the state of receiving / delivering balls, when the first valve is closed, the connection between the upper ball storage chamber and the middle ball storage chamber is cut, and the collected rubber balls are temporarily stored in the upper ball storage chamber. When the first valve is opened, the upper ball storage chamber and the middle ball storage chamber are connected, and the rubber balls enter the middle ball storage chamber with the water flow. After all the rubber balls enter the middle ball storage chamber, the first valve is closed and the next ball receiving and delivering is waited. The single first valve can be used to control the connection or cutting between the upper ball storage chamber and the middle ball storage chamber, which is easy to control and makes the structure simple and reliable. The first valve can adopt a butterfly valve structure, which has stable and reliable sealing and avoids the problem of water leakage due to poor sealing.

[0009] In some embodiments, the second valve includes a second valve plate, a second rotating shaft and an O-ring. The second rotating shaft is disposed on a side wall of the second cylindrical wall and is driven to rotate by a second driving motor.

[0010] According to this solution, the valve plate of the second valve cooperates with the O-ring to seal when the system is under static pressure. The greater the pressure of the main pipeline, the better the sealing effect, avoiding the problem that the conventional sealing structure is easy to fail under high pressure. Therefore, this sealing method is stable and reliable, and can ensure that there is no water leakage in the ball storage chamber when the rubber ball is replaced. The second valve can adopt a check valve structure, which will not occupy a large flow area when it is opened, avoiding the blockage of the rubber ball when serving.

[0011] In some embodiments, the first port and the second port in the lower portion of the second cylindrical wall are arranged on opposite sides in the diameter direction, the water intake pipe has a first 90-degree elbow and a first bellows, the serving pipe has a second 90-degree elbow and a second bellows, and the first bellows and the second bellows are connected to the same side of the water inlet pipe.

[0012] According to this solution, water enters the lower ball storage chamber through the water intake pipe, flushes the rubber balls out along the ball launching pipe, and enters the main water inlet pipe to launch the balls. The water intake pipe and the ball launching pipe are on the same side of the main water inlet pipe, which can reduce the water flow area and reduce the water flow resistance. The corrugated pipe structure is retractable, so that the center distance between the water inlet pipe and the middle ball storage chamber / lower ball storage chamber can be adjusted, which facilitates the flexibility of on-site installation of the device.

[0013] In some embodiments, the proximal opening of the water intake bend is connected to the inner side of the first port, and the distal opening faces upstream of the water inlet pipe; the proximal opening of the serving bend is connected to the inner side of the second port, and the distal opening faces downstream of the water inlet pipe, and the center of the distal opening is basically aligned with the center of the water inlet pipe.

[0014] According to this solution, the rubber balls are emitted from the center of the main pipe, and the probability of emission is evenly distributed, which improves the cleaning efficiency.

[0015] In some schemes, a baffle is provided inside the upper ball storage chamber, and the baffle has a partition, which divides the upper ball storage chamber into a ball storage channel and a water outlet channel. The ball storage channel is connected to the ball receiving port, and the water outlet channel is connected to the water outlet.

[0016] According to the scheme, the baffle separates the upper ball storage chamber into a ball storage channel and a water outlet channel. When the first valve is closed, the rubber balls entering from the ball receiving port are intercepted in the ball storage channel, and the water flow entering from the ball receiving port is discharged from the water outlet channel and the water outlet. Since the rubber balls are retained in the ball storage channel and away from the water outlet pipe, they will not cause water pressure fluctuations in the water outlet pipe, allowing the system to operate smoothly.

[0017] In some solutions, the baffle further has a mesh portion, which is located between the baffle and the butterfly valve and between the ball storage channel and the water outlet channel.

[0018] According to this scheme, the mesh part performs the first ball-water separation on the rubber balls and the water flow. When the first valve is closed, the rubber balls entering the upper ball storage chamber are blocked by the mesh part, while the water flow can pass through the mesh part and flow out from the outlet on the other side of the baffle, completing the ball collecting process and enabling the system to run smoothly.

[0019] In some embodiments, the baffle further comprises a first fan-shaped plate and a second fan-shaped plate. The first straight edge of the first fan-shaped plate is connected to the upper side of the mesh portion, the second straight edge is connected to the first side of the partition portion, the first straight edge of the second fan-shaped plate is connected to the lower side of the mesh portion, and the second straight edge is connected to the second side of the partition portion, so that the first fan-shaped plate blocks the rubber balls in the ball storage channel from directly moving to the upper side of the mesh portion, and the second fan-shaped plate blocks the rubber balls on the lower side of the mesh portion from directly moving to the water outlet channel.

[0020] According to this solution, after the rubber ball enters the ball storage channel of the first ball storage chamber along with the water flow, the first fan-shaped plate blocks the rubber ball in the ball storage channel from moving directly to the upper side of the mesh portion, thereby preventing the rubber ball from flowing out of the water outlet channel directly along with the water flow, and the second fan-shaped plate blocks the rubber ball on the lower side of the mesh portion from moving directly to the water outlet channel. The two fan-shaped plates block the rubber ball from flowing out of the ball storage chamber, thereby achieving effective ball collection.

[0021] In some embodiments, the first sector plate and the second sector plate are solid plates or perforated plates.

[0022] According to the scheme, the rubber balls can be effectively blocked.

[0023] In some embodiments, the rubber ball cleaning device further includes a length-adjustable connecting device installed between the water inlet pipe and the water outlet pipe.

[0024] According to this solution, the center distance between the water inlet pipe and the water outlet pipe can be adjusted, which facilitates the flexibility of on-site installation of the device.

[0025] In a second aspect, a heat exchange device is provided, comprising the horizontal rubber ball cleaning device for pipe ends as described in any one of the above items.

[0026] According to this solution, the heat exchange equipment can promptly remove sediments such as sludge and dissolved salts deposited on the inner wall of the heat exchange tube, thereby ensuring heat exchange efficiency, long operating life, and excellent comprehensive performance.

DETAILED DESCRIPTION

[0034] In order to make the purpose, scheme and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described in conjunction with the drawings of the specific embodiments of the utility model. Unless otherwise specified, the terms used in this article have the usual meanings in the art. The same or corresponding reference numerals in the drawings represent the same or corresponding parts.

[0035] Figure 1 A schematic diagram of a rubber ball cleaning device of the utility model is shown. Figure 1 Combination Figure 2 , Figure 3 From the perspective of the rubber ball cleaning device 100, the rubber ball cleaning device 100 includes: a water inlet pipe 110, the side wall of which is provided with a water inlet 111 and a ball outlet 112 (the water inlet and the ball outlet are shown in FIG. Figure 2 ); the outlet pipe 120 is arranged horizontally and parallel to the inlet pipe 110, and its side wall is provided with a ball receiving port 121 and a water outlet 122; specifically, a ball receiving pipe 132 is connected to the upper side of the inlet pipe 110, and the inside of the ball receiving pipe 132 is divided into two channels corresponding to the ball receiving port 121 and the water outlet 122 by a partition, and the ball receiving pipe 132 is connected to the opening on the upper first cylindrical wall 131; the upper ball storage chamber 130 is surrounded by the first cylindrical wall 131, and the first cylindrical wall 131 is connected to the outlet pipe 120 through the ball receiving pipe 132, as shown in FIG. Figure 1 As shown, the first cylindrical wall 131 is located on the upper side of the water outlet pipe 120; the middle ball storage chamber 140 is surrounded by the upper part of the second cylindrical wall 141, the second cylindrical wall 141 is arranged vertically with the first cylindrical wall 131, the upper part of the second cylindrical wall 141 is provided with a window 142 for replacing the rubber ball, and the second cylindrical wall 141 is located between the water inlet pipe 110 and the water outlet pipe 120; the lower ball storage chamber 150 is surrounded by the lower part of the second cylindrical wall 141, the lower part of the second cylindrical wall 141 is provided with a first port 151 and a second port 152, the first port 151 is connected to the water intake port 111 through a water intake pipe 153, and the second port 152 is connected to the ball serving port 112 through a ball serving pipe 154 (the structure of the first port, the second port, the water intake pipe and the ball serving pipe is shown in Figure 2 The first valve 160 is sandwiched between the first cylindrical wall 131 and the second cylindrical wall 141, and is used to connect or cut off the communication between the upper ball storage chamber 130 and the middle ball storage chamber 140; the second valve 170 is located in the middle of the second cylindrical wall 141, and is used to connect or cut off the communication between the middle ball storage chamber 140 and the lower ball storage chamber 150. Since the outlet pipe 120 and the inlet pipe 110 of the rubber ball cleaning device 100 are arranged horizontally in parallel, the device can be adapted for use on heat exchange equipment with the inlet and outlet pipes 120 arranged horizontally in parallel, and the sediment on the inner wall of the pipe of such heat exchange equipment can be cleaned. The second cylindrical wall 141 of the rubber ball cleaning device 100 is arranged vertically with the first cylindrical wall 131, and the inner and outer cylinder structure is not adopted, so as to avoid the deposition of rust or sludge that hinders the use of the equipment and ensure the normal operation of the system.

[0036] Although the second cylindrical wall shown in the drawings is an integrated cylinder, the utility model is not limited to this. The second cylindrical wall can be formed by connecting cylinders that define the middle ball storage chamber and the lower ball storage chamber. In this case, the second valve can be arranged between the two cylinders. This deformation constitutes an equivalent deformation of the embodiment shown in the drawings and falls within the protection scope of this patent.

[0037] In the illustrated embodiment, the rubber ball cleaning device 100 further includes a length-adjustable connecting device 180, which is installed between the water inlet pipe 110 and the water outlet pipe 120, so that the center distance between the water inlet pipe 110 and the water outlet pipe 120 can be adjusted, which facilitates the flexibility of the device on-site installation. The above scheme including the length-adjustable connecting device 180 is only a specific embodiment, and the utility model is not limited thereto.

[0038] Figure 2 The structure of the water intake / ball serving assembly of the device is shown. As shown in the figure, the lower part of the second cylindrical wall 141 is provided with a first port 151 and a second port 152. The first port 151 is connected to the water intake port 111 through a water intake pipe 153, and the second port 152 is connected to the ball serving port 112 through a ball serving pipe 154. The first port 151 and the second port 152 are arranged on opposite sides of the diameter direction. The water intake pipe 153 has a first 90-degree elbow 1531 and a first corrugated pipe 1532. The ball serving pipe 154 has a second 90-degree elbow 1521 and a second corrugated pipe 1522. The first corrugated pipe 1532 and the second corrugated pipe 1522 are connected to the same side of the water inlet pipe. The water in the water inlet main pipe enters the lower ball storage chamber 150 through the water intake pipe 153, flushes the rubber ball along the ball serving pipe 154, and enters the main pipe of the water inlet pipe 110 to achieve ball serving. The water intake pipe 153 and the ball serving pipe 154 are arranged on the same side of the water inlet main pipe, which can reduce the water flow area, reduce the water flow resistance, and make the ball serving operation smoother. In addition, the bellows structure is retractable, so that the center distance between the water intake pipe 110 and the middle ball storage chamber 140 / lower ball storage chamber 150 can be adjusted, which facilitates the flexibility of the device on-site installation. The above schemes of the water intake pipe 153 and the ball serving pipe 154 are only specific embodiments, and the utility model is not limited thereto.

[0039] In the illustrated embodiment, the water intake pipe 153 further includes a water intake bend pipe 113, whose proximal opening is connected to the inner side of the first port 151 located inside the water inlet pipe 110, and whose distal opening faces the upstream of the water inlet pipe 110; the ball serving pipe 154 further includes a ball serving bend pipe 114, whose proximal opening is connected to the inner side of the second port 152, whose distal opening faces the downstream of the water inlet pipe 110, and whose center is substantially aligned with the center of the water inlet pipe 110. The above-mentioned bend pipe structure can make the rubber ball be sent out from the center of the main pipeline, with a uniform distribution of the probability of serving, thereby improving the serving efficiency. The above-mentioned scheme including the water intake bend pipe 113 and the ball serving bend pipe 114 is only a specific embodiment, and the utility model is not limited thereto.

[0040] Figure 3The structure of the baffle 133 of the upper ball storage chamber 130 is shown. The baffle 133 is arranged inside the upper ball storage chamber 130. The baffle 133 has a partition 1331. The partition 1331 divides the upper ball storage chamber 130 into a ball storage channel 134 and a water outlet channel 135. The ball storage channel 134 is connected to the ball receiving port 121, and the water outlet channel 135 is connected to the water outlet 122. The rubber balls entering from the ball receiving port 121 are intercepted in the ball storage channel 134, and the water flow entering from the ball receiving port 121 is discharged from the water outlet channel 135 and the water outlet 122. Since the rubber balls are trapped in the ball storage channel 134 and away from the water outlet pipe 120, the water pressure fluctuation in the water outlet pipe 120 will not be caused, so that the system can run smoothly.

[0041] The baffle 133 also has a mesh portion 1332, which is located between the baffle 133 and the first valve 160, and performs a first ball-water separation on the rubber ball and the water flow. When the first valve 160 is closed, the rubber ball is blocked by the mesh portion 1332, while the water flow can pass through the mesh portion 1332 and flow out from the water outlet 122 on the other side of the baffle 133. The rubber ball is temporarily retained in the space surrounded by the first valve and the baffle, completing the ball collecting process.

[0042] The baffle 133 also has a first fan-shaped plate 1333 and a second fan-shaped plate 1334. Each fan-shaped plate can be a 90-degree fan-shaped plate, which has two right-angled sides and a circular arc side, and the circular arc side is connected to the inner wall of the first cylindrical wall 131. The first straight side of the first fan-shaped plate 1333 is connected to the upper side of the mesh part 1332, and the second straight side is connected to the first side of the partition 1331. The first straight side of the second fan-shaped plate 1334 is connected to the lower side of the mesh part 1332, and the second straight side is connected to the second side of the partition 1331. Thus, the mesh part 1332 and the partition 1331 are arranged vertically to divide the circular inner circumference of the first cylindrical wall 131 into four quadrants. The first fan-shaped plate 1333 and the second fan-shaped plate 1334 occupy two opposite quadrants, which can block the rubber ball from passing through, and the other two opposite quadrants are not blocked and can be freely passed by the rubber ball. This arrangement enables the first fan-shaped plate 1333 to block the rubber balls in the ball storage channel 134 from directly moving to the upper side of the mesh portion 1332, and the second fan-shaped plate 1334 to block the rubber balls on the lower side of the mesh portion 1332 from directly moving to the water outlet channel 135. After the rubber balls enter the ball storage channel 134 of the first ball storage chamber along with the water flow, the first fan-shaped plate 1333 blocks the rubber balls in the ball storage channel 134 from directly moving to the upper side of the mesh portion 1332, thereby preventing the rubber balls from directly flowing out of the water outlet channel 135 along with the water flow, and the second fan-shaped plate 1334 blocks the rubber balls on the lower side of the mesh portion 1332 from directly moving to the water outlet channel 135. The two fan-shaped plates block the rubber balls from flowing out of the ball storage chamber, thereby achieving effective ball collection.

[0043] In the illustrated embodiment, the first sector plate 1333 and the second sector plate 1334 are solid plates, but the present invention is not limited thereto, and the sector plates may also be perforated plates that can effectively block the rubber balls. The above baffle 133 solution is only a specific embodiment, and the present invention is not limited thereto.

[0044] Figure 4 , Figure 5 , Figure 6 The structure of the first valve of the utility model is shown. The first valve 160 is a butterfly valve, including a first valve plate 161 and a first rotating shaft 162. Figure 1 The first driving motor 163 shown drives the first rotating shaft 162 to rotate, and its rotating shaft is substantially perpendicular to the center line of the first cylindrical wall 131 .

[0045] like Figure 4 As shown, in the ball taking / putting state, the first valve 160 is closed, and the sealing performance of the butterfly valve structure is stable and reliable, thereby avoiding the problem of water leakage when taking / putting the ball.

[0046] like Figure 5 As shown, in the ball collecting / discharging state, when the first valve 160 is closed, the connection between the upper ball storage chamber 130 and the middle ball storage chamber 140 is cut, and after the rubber ball enters the upper ball storage chamber 130, it is intercepted in the space surrounded by the baffle 133 and the first valve, and the water flows into the water outlet channel 135 through the mesh portion 1332 of the baffle 133, and the rubber ball is temporarily stored in the upper ball storage chamber 130. The ball collecting process is completed by closing the first valve 160.

[0047] like Figure 6 As shown, after the ball collection is completed, the first valve 160 is opened, and the upper ball storage chamber 130 is connected to the middle ball storage chamber 140, while the mesh portion 1332 of the baffle 133 is blocked by the valve plate of the first valve 160, and the ball-water separation is no longer achieved. The rubber balls temporarily stored in the upper ball storage chamber 130 through the ball collection operation enter the middle ball storage chamber 140 from the upper ball storage chamber 130 with the water flow, and the filter mesh plate of the middle ball storage chamber 140 acts as a ball-water separator to filter the water flow, and the water flows out through the water outlet channel 135, while the rubber balls fall into the middle ball storage chamber 140. After all the rubber balls enter the middle ball storage chamber 140, the first valve 160 is closed, waiting for the next ball collection and delivery. The single first valve 160 can be used to realize the control of the connection or segmentation between the upper ball storage chamber 130 and the middle ball storage chamber 140, which is convenient to control and makes the structure simple and reliable.

[0048] Figure 4 , Figure 5 , Figure 6 The structure of the second valve of the utility model is shown in FIG. 1 . The second valve 170 is a check valve, and its structure includes a second valve plate 171, a second rotating shaft 172 and an O-ring 173. The second rotating shaft 172 is arranged on the side wall of the second cylindrical wall 141. Figure 1 The second drive motor 174 is shown to drive the second rotating shaft 172 to rotate.

[0049] like Figure 4 As shown, in the ball taking / putting state, the valve plate of the second valve 170 cooperates with the O-ring 173 to seal when the system is under static pressure. The greater the pressure of the main pipeline, the better the sealing effect, thereby avoiding the problem that the conventional sealing structure is prone to failure under high pressure. Therefore, this sealing method is stable and reliable, and can ensure that there is no water leakage in the ball storage chamber 140 when replacing the rubber ball.

[0050] like Figure 5 As shown, in the ball receiving / serving state, the second valve 170 is opened, the rubber ball falls into the lower ball storage chamber 150, and the water in the water inlet pipe 110 enters the lower ball storage chamber 150 through the water intake pipe 153, flushing the rubber ball out to serve the ball. The second valve 170 adopts a check valve structure, which will not occupy a large flow area when opened, thereby avoiding blockage of the rubber ball when serving the ball.

[0051] like Figure 6 As shown, after serving and receiving the ball, the second valve 170 is closed, and the rubber ball flows from the upper ball storage chamber 130 into the middle ball storage chamber 140 to wait for the next serving, thereby ensuring the continuous and stable operation of the system.

[0052] The device of the utility model can be divided into a stop / standby (taking / putting balls) state, a ball receiving / delivering state, and a rubber ball recovery state according to different operation stages.

[0053] Figure 4 This is the shutdown / standby (taking / putting balls) state of the utility model. When the first valve 160 and the second valve 170 are closed, the upper, middle and lower ball storage chambers are not connected, the system does not work, and the rubber balls are stored in the middle ball storage chamber 140. At this time, the system enters the taking / putting ball state, and the taking / putting ball operation can be performed through the window 142.

[0054] Figure 5 This is the working state of receiving / delivering the ball of the utility model. In this state, the first valve 160 is closed, the second valve 170 is opened, and the rubber ball falls into the lower ball storage chamber 150. Figure 2From the perspective of the water intake / ball serving assembly structure, water in the water inlet pipe 110 enters the lower ball storage chamber 150 through the water intake pipe 153, flushes the rubber balls in the lower ball storage chamber 150 along the ball serving pipe 154, and serves the balls. The rubber balls follow the water flow through the main pipeline into the heat exchange equipment, clean the inner wall of the heat exchange equipment, and come out from the water outlet pipe 120 of the heat exchange equipment. Then, they follow the water flow through the ball receiving port 121 of the ball receiving pipe 132 into the upper ball storage chamber 130. Because a baffle 133 is provided inside the upper ball storage chamber 130, the rubber balls are isolated in one side of the baffle 133, namely, in the ball storage channel 134, and the water flows into the water outlet channel 135 through the mesh portion 1332. The mesh portion 1332 serves as a ball-water separator to complete the ball-water separation. Because the rubber balls cannot pass through the mesh portion 1332, they are intercepted in the space surrounded by the baffle 133 and the first valve 160, completing the ball receiving process.

[0055] Figure 6 The working state of the rubber ball recovery of the utility model is shown. Figure 5 After the ball collecting operation shown, the second valve 170 is closed and the first valve 160 is opened. At this time, the upper ball storage chamber 130 and the middle ball storage chamber 140 are connected, and the mesh portion 1332 is blocked by the valve plate of the first valve 160 and no longer functions as a ball-water separator. The rubber balls temporarily stored in the upper ball storage chamber 130 through the ball collecting operation flow into the middle ball storage chamber 140 from the upper ball storage chamber 130 along with the water flow. The filter mesh plate of the middle ball storage chamber 140 acts as a ball-water separator to filter the water flow, and the water flows out through the water outlet channel 135, while the rubber balls fall into the middle ball storage chamber 140. After all the rubber balls have entered the middle ball storage chamber 140, the first valve 160 is closed, and the next cycle of sending and receiving balls is entered, thereby realizing continuous and stable operation of the system.
