[0002] At present, the rubber ball system is widely used in central air-conditioning systems, playing the role of real-time online cleaning of the heat exchange tubes of the air-conditioning host. The rubber ball system can keep the heat exchange tubes clean, improve the operating efficiency of the air-conditioning, and reduce the energy consumption of the air-conditioning. It is an air-conditioning energy-saving equipment. Its basic principle is to use the rubber ball system to launch a certain number of small balls into the air-conditioning circulating water system. When the small balls pass through the heat exchange tube with the circulating water, they squeeze and scrub the inner wall of the heat exchange tube to remove the dirt deposited on the inner wall and keep the heat exchange tube clean. For example, a Chinese patent application with application number 201921573071.5 discloses a horizontal ball-launching and ball-collecting water separator, comprising an outer cylinder, on the side wall of which a ball-collecting port, a water outlet, a ball-launching port and a water inlet are provided; the water inlet and the water outlet are both connected to an inlet-outlet water control valve, the inlet-outlet water control valve comprises an inner cylinder placed in the outer cylinder, the inner cylinder is provided with a partition for dividing the inner cavity of the inner cylinder into a first inner cavity and a second inner cavity which are independent of each other, the inner cylinder side wall of the first inner cavity is provided with two first openings corresponding to the ball-launching port and the water outlet respectively, the first inner cavity is provided with a ball-water separation filter screen; the inner cylinder side wall of the second inner cavity is provided with two A second opening corresponding to the ball serving port and the water inlet respectively, and a ball-water separation filter is arranged in the second inner cavity. This structure is a representative structural form of rubber ball cleaning equipment. During operation, the ball storage chamber is placed in a ball receiving position or a ball serving position by rotating the inner cylinder of the ball storage chamber, and the ball receiving and serving actions are realized by using the power of circulating water. However, the inner cylinder of this application is divided into two halves by a partition, but its space utilization rate is low, and in this application, only a ball-water separation filter is used in the inner cylinder for ball-water separation. After long-term operation of the equipment, bacteria, algae, silt, etc. are often produced in the circulating water and attached to the screen, so it needs to be disassembled and cleaned regularly, which increases the maintenance cost.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0027] like Figures 1 to 9As shown, a tube-end rubber ball system comprises a main cylinder 1, a ball storage room cylinder 2, a ball storage room cylinder 3, and a mesh plate 4. The cylinder wall of the ball storage room cylinder 2 is provided with a ball receiving port 21, a water return port 22, a ball serving port 23, and a water inlet 24. The ball storage room cylinder 2 is located at one side of the main cylinder 1. The ball receiving port 21 is connected to the main cylinder 1 through a ball receiving water inlet pipe 5. The water return port 22 is connected to the main cylinder 1 through a water return pipe 6. The ball storage room cylinder 3 is sleeved on the ball storage room cylinder 2. Inside the outdoor cylinder 2, a notch A31 and a notch B32 are provided on the inner cylinder 3 of the ball storage room, and the positions of the notch A31 and the notch B32 correspond to the ball receiving port 21 and the water return port 22 respectively, and after the inner cylinder 3 of the ball storage room rotates 180°, the notch A31 and the notch B32 are aligned with the ball serving port 23 and the water inlet 24 respectively, and the mesh plate 4 is tiltedly installed in the main cylinder body 1 through the rotating shaft, and one end of the mesh plate 4 blocks the connection between the ball receiving water inlet pipe 5 and the main cylinder body 1.

[0028] In the ball serving stage, the inner cylinder 3 of the ball storage room is driven by the actuator 25 so that its notch A31 and notch B32 are aligned with the ball serving port 23 and the water inlet 24 respectively. At the same time, the water intake pipe 14 introduces part of the water on the water inlet pipe of the air conditioner main unit into the inner cylinder 3 of the ball storage room through the water intake baffle and the pressure difference between the water intake pipe 14 and the ball serving pipe 15. After the water flows through the filter screen 33, the rubber ball in the inner cylinder 3 of the ball storage room is brought into the water inlet pipe of the air conditioner main unit, completing the ball serving action; in the ball receiving stage, the inner cylinder 3 of the ball storage room is driven by the actuator 25 so that its notch A31 and notch B32 are aligned with the ball receiving port 23 and the water inlet 24 respectively. 21 and return water port 22, and at the same time, the mesh plate 4 rotates under the drive of the worm gear head 7, and the upper end of the mesh plate 4 blocks the connection between the ball receiving water inlet pipe 5 and the main cylinder body 1. When water flows through the mesh plate 4, a part of the water flows directly through the mesh plate 4, and because the mesh holes of the mesh plate 4 are smaller than the rubber balls, after being blocked by the mesh plate 4, the rubber balls, driven by another part of the water flow and guided by the mesh plate 4, enter the ball storage chamber inner cylinder 3 from the ball receiving water inlet pipe 5. In the ball storage chamber inner cylinder 3, the water flow can flow through the filter screen 33 normally, and the rubber balls are blocked by the filter screen 33 and remain in the ball storage chamber inner cylinder 3, thereby realizing the ball collecting action.

[0029] An actuator 25 is provided on one side of the outer cylinder 2 of the ball storage chamber, and a cover plate A26 is provided on the other side. The actuator 25 is fixed on the outer cylinder 2 of the ball storage chamber, and is connected to the inner cylinder 3 of the ball storage chamber through a rotating shaft, and a sealed bearing is provided between the rotating shaft and the outer cylinder 2 of the ball storage chamber. One side of the cover plate A26 is hinged to the outer cylinder 2 of the ball storage chamber, and the other side is connected to the outer cylinder 2 of the ball storage chamber through a lifting nut 27. The actuator 25 is a reduction motor. Under the control of the controller, the actuator 25 can drive the inner cylinder 3 of the ball storage chamber to rotate, thereby switching different working states, so that the inner cylinder 3 of the ball storage chamber has the functions of receiving and sending balls and storing balls, thereby greatly simplifying the structure of the equipment.

[0030] The main cylinder body 1 is provided with a worm gear head 7, which is fixed to the outer wall of the main cylinder body 1 and connected to the rotating shaft on the mesh plate 4. The worm gear head 7 can drive the mesh plate 4 to rotate in the main cylinder body 1. In the ball collecting stage, the mesh plate 4 can be used to separate the rubber balls and the water flow, and the rubber balls can be introduced into the inner cylinder 3 of the ball storage chamber. After the equipment has been working for a long time, since bacteria, algae, silt, etc. often adhere to the mesh plate 4 in the circulating water, it is necessary to open the mesh plate 4 to the self-cleaning state. At this time, the mesh plate 4 is driven by the worm gear head 7 to tilt to the other side in the reverse direction, and the water flow is used to flush the mesh plate 4 in the reverse direction, thereby realizing the self-cleaning of the mesh plate, without the need for manual cleaning, and maintaining the normal ball collecting effect of the mesh plate.

[0031] The notch B32 is covered with a filter screen 33, and in the ball collection stage, the rubber balls in the inner cylinder 3 of the ball storage chamber and the water flow can be separated by the filter screen 33, so that the rubber balls can be retained in the inner cylinder 3 of the ball storage chamber.

[0032] A ball guide plate 41 is provided at one end of the mesh plate 4. The ball guide plate 41 is installed in an eight-shaped shape on the ball guide plate 41. The ball guide plate 41 plays a guiding role, so that the rubber ball can enter the inner cylinder 3 of the ball storage chamber from the mesh plate 4 more smoothly.

[0033] A sealing structure is arranged between the ball receiving port 21, the water return port 22, the ball serving port 23, the water inlet 24 and the outer cylinder 3 of the ball storage room, and the sealing structure comprises a flange A8, a liner pressure ring 9, and a sealing liner 10. One end of the sealing liner 10 is inserted into the outer cylinder 2 of the ball storage room and squeezed on the outer wall of the inner cylinder 3 of the ball storage room. The other end of the sealing liner 10 is connected to the outer cylinder 2 of the ball storage room through the liner pressure ring 9, and an O-ring 11 is arranged between the sealing liner 10 and the inner wall of the outer cylinder 2 of the ball storage room. The flange A8 It is covered on the liner pressure ring 9 and connected to the outer cylinder 2 of the ball storage chamber by screws, and a gasket 12 is provided between the flange A8 and the liner pressure ring 9. Under the extrusion of the liner pressure ring 9, the sealing liner 10 is tightly attached to the outer wall of the outer cylinder 3 of the ball storage chamber to achieve the sealing effect. At the same time, an O-ring 11 is provided between the sealing liner 10 and the outer cylinder 2 of the ball storage chamber. The O-ring 11 is squeezed by the sealing liner 10 and the liner pressure ring 9 so that it can be tightly attached to the inner wall of the outer cylinder 2 of the ball storage chamber to achieve the sealing effect.

[0034] The material of the sealing liner 10 is polytetrafluoroethylene, which is a high molecular polymer obtained by polymerization of tetrafluoroethylene as a monomer. It has excellent heat and cold resistance, and is resistant to acids and alkalis. At the same time, polytetrafluoroethylene is resistant to high temperatures and has an extremely low friction coefficient. It is an ideal material for lubricating seals, so that the connection between the sealing liner 10 and the inner tube 3 of the ball storage chamber can maintain a long-term sealed connection.

[0035] Both ends of the main cylinder 1 are provided with flanges B13. The main cylinder 1 is installed on the water outlet pipe of the air conditioner main unit. The water inlet 24 is connected to the water inlet pipe of the air conditioner main unit through the water intake pipe 14. The ball-serving port 23 is connected to the water inlet pipe of the air conditioner main unit through the ball-serving pipe 15. The ball-serving pipe 15 is closer to the air conditioner main unit than the water intake pipe 14. A water intake baffle is provided at the connection between the water intake pipe 14 and the water inlet pipe of the air conditioner main unit.

[0036] When serving, the water intake pipe 14 introduces part of the water on the water inlet pipe of the air conditioner main unit into the inner cylinder 3 of the ball storage chamber through the water intake baffle and the pressure difference between the water intake pipe 14 and the serving pipe 15. When collecting the balls, the water flow in the water outlet pipe of the air conditioner main unit can bring the rubber balls into the inner cylinder 3 of the ball storage chamber through the interception of the mesh plate 4, thereby achieving the effect of collecting and storing the balls.

[0037] The main cylinder 1 and the cover plate A26 are both provided with observation windows for conveniently observing the internal conditions of the equipment during operation.

[0038] The main cylinder 1 and the outer cylinder 2 of the ball storage chamber intersect in a cross shape, and the intersection is a ball receiving water inlet pipe 5. The equipment has a compact structure, a short operating channel, and strong installation adaptability.
