Description

Technical Field

[0001] The invention relates to the technical field of central air-conditioning cleaning equipment, and in particular to a split end-cap type rubber ball cleaning device. Background Art

[0002] When the central air conditioner is running, cooling water flows inside the heat exchange tubes of the condenser. After running for a long time, the sludge and dissolved salt in the cooling water will be deposited on the inner wall of the heat exchange tubes, resulting in a serious decrease in heat exchange efficiency.

[0003] Users usually use an end-cap type rubber ball cleaning device to clean the inner wall of the heat exchange tube. The diameter of the rubber ball thrown by the end-cap type rubber ball cleaning device is slightly larger than the inner diameter of the heat exchange tube. The rubber ball is elastically deformed and moves when it is pushed into the heat exchange tube by cooling water. Therefore, the rubber ball can be used to scrub the inner wall of the heat exchange tube and remove dirt on the inner wall of the heat exchange tube.

[0024] The present invention provides a split end-cap type rubber ball cleaning device. When it is necessary to clean the heat exchange tubes of the condenser, water flows into the water inlet pipe from the outside. Part of the water flowing into the water inlet pipe flows into the second end of the water intake pipe and flows into the lower ball storage chamber from the first end of the water intake pipe, and pushes the rubber ball in the lower ball storage chamber into the first end of the ball delivery pipe. After passing through the ball delivery pipe, the rubber ball enters the water inlet pipe from the second end of the ball delivery pipe. The water flow in the water inlet pipe drives the rubber ball into the heat exchange tube of the condenser, so that the inner wall of the heat exchange tube is washed by the rubber ball, thereby improving the heat exchange efficiency of the heat exchange tube. After passing through the heat exchange tube, the rubber ball enters the water outlet pipe, and is blocked at the place where the first filter screen is installed on the water outlet pipe. The first filter screen guides the rubber ball to pass through the ball receiving port and enter the upper ball storage chamber. Since the water flow pressure of the water outlet pipe is less than that of the water inlet pipe, The water flow pressure in the water pipe, therefore, the pressure in the upper ball storage chamber is less than the pressure in the lower ball storage chamber, and the pressure on the lower end face of the check valve plate is greater than the pressure on the upper end face, so the check valve plate rotates and blocks between the upper ball storage chamber and the lower ball storage chamber, and at this time, the rubber balls in the upper ball storage chamber cannot fall into the lower ball storage chamber; when all the rubber balls are retracted into the upper ball storage chamber, the inner cylinder is driven to rotate relative to the outer cylinder, and the second interface of the inner cylinder, the water intake pipe and the ball delivery pipe are all blocked by the inner wall of the outer cylinder. Therefore, the pressure in the upper ball storage chamber tends to be balanced with the pressure in the lower ball storage chamber, and the pressure on the upper end face of the check valve plate is equal to the pressure on the lower end face, and the check valve plate rotates due to its own gravity, and the upper ball storage chamber is connected with the lower ball storage chamber, and at this time, the rubber balls in the upper ball storage chamber automatically fall into the lower ball storage chamber.

The check valve plate 35 is rotatably connected to the inner wall of the inner cylinder 32 along the horizontal axis, and the check valve plate 35 can divide the inner cavity of the inner cylinder 32 into an upper ball storage chamber and a lower ball storage chamber. The side wall of the upper ball storage chamber is provided with a second interface 321, and the second interface 321 can be selectively connected to the first interface 101; the first end of the water intake pipe 5 is connected to the lower ball storage chamber, and the second end of the water intake pipe 5 is connected to the water inlet pipe 2; the first end of the ball serving pipe 6 is connected to the lower ball storage chamber, and the second end of the ball serving pipe 6 is connected to the water inlet pipe 2.

[0047] The ball receiving port 102 is located at a side of the first filter screen 4 facing the water flow, and the water return port 103 is located at a side of the first filter screen 4 facing away from the water flow.

[0048] Optionally, two outer cylinders 31 are provided, the upper outer cylinder 31 is connected to the first interface 101 , and the lower outer cylinder 31 is connected to the water intake pipe 5 and the ball serving pipe 6 .

[0049] Specifically, the water inlet and outlet of the condenser 100 are respectively located on both sides of its body. In this embodiment, the water inlet pipe 2 is installed at the water inlet end of the condenser 100, and the water outlet is installed at the water outlet end of the condenser 100 to ensure that it can match the specific structure of the condenser 100.

[0050] Specifically, when it is necessary to clean the heat exchange tubes of the condenser 100, water flows from the outside into the water inlet pipe 2. Part of the water flowing into the water inlet pipe 2 flows into the second end of the water intake pipe 5 and flows into the lower ball storage chamber from the first end of the water intake pipe 5, and pushes the rubber balls in the lower ball storage chamber into the first end of the ball serving pipe 6. After passing through the ball serving pipe 6, the rubber balls enter the water inlet pipe 2 from the second end of the ball serving pipe 6. The water flow in the water inlet pipe 2 drives the rubber balls into the heat exchange tubes of the condenser 100, so that the inner wall of the heat exchange tube is washed by the rubber balls, thereby improving the heat exchange efficiency of the heat exchange tubes. After passing through the heat exchange tubes, the rubber balls enter the water outlet pipe 1, and are blocked at the place where the first filter screen 4 is installed on the water outlet pipe 1. The first filter screen 4 guides the rubber balls through the ball receiving port 102 and enters the upper ball storage chamber. Since the water inlet pressure is greater than the water outlet pressure, and the lower ball storage chamber is connected to the water inlet pipe 2 through the water intake pipe 5, the upper ball storage chamber is connected to the outlet The water pipe 1 is connected, so the pressure in the upper ball storage chamber is less than that in the lower ball storage chamber, and the pressure on the lower end face of the check valve plate 35 is greater than the pressure on the upper end face, so the check valve plate 35 rotates and blocks between the upper ball storage chamber and the lower ball storage chamber, and the rubber balls in the upper ball storage chamber cannot fall into the lower ball storage chamber at this time; when all the rubber balls are recovered to the upper ball storage chamber, the inner cylinder 32 is driven to rotate relative to the outer cylinder 31, and the second interface 321 of the inner cylinder 32 and the third interface 322 connected to the water intake pipe 5 and the ball delivery pipe 6 at the same time are blocked by the inner wall of the outer cylinder 31. Therefore, the pressure in the upper ball storage chamber tends to be balanced with the pressure in the lower ball storage chamber, and the pressure on the upper end face of the check valve plate 35 is equal to the pressure on the lower end face, and the check valve plate 35 rotates by its own gravity, and the upper ball storage chamber is connected to the lower ball storage chamber, and the rubber balls in the upper ball storage chamber automatically fall into the lower ball storage chamber.

[0051] Optionally, the port at the second end of the water intake pipe 5 faces the direction of water flow to ensure the water flow pressure entering the water intake pipe 5 and reduce the attenuation of the water flow pressure in the water intake pipe 5. The port at the second end of the serving tube 6 is parallel to the direction of water flow to prevent the water flow in the water inlet pipe 2 from flowing back into the serving tube 6.

The first partition 33 separates the third interface 322 into a water inlet and a ball serving port. The first end of the water inlet pipe 5 is connected to the water inlet, and the first end of the ball serving pipe 6 is connected to the ball serving port. After the water flows into the water inlet from the first end of the water inlet pipe 5, it encounters the obstruction of the first partition 33 and goes around to the bottom of the lower ball storage chamber to stir the rubber balls, so that the rubber balls in the lower ball storage chamber pass through the ball serving port and enter the ball serving pipe 6, so as to prevent the water from entering the water inlet from the first end of the water inlet pipe 5 and then directly passing through the ball serving port into the ball serving pipe 6 without causing the rubber balls to enter the ball serving pipe 6.

The first filter screen 4 can guide the rubber ball to enter the ball receiving chamber after passing through the ball receiving port 102, and the partition net 34 can block the rubber ball in the ball receiving chamber, while the water flow entering the ball receiving chamber can pass through the mesh of the partition net 34, the water return chamber and the water return port 103 in sequence, so that the water flow can return to the water outlet pipe 1. The partition net 34 can prevent the rubber ball from returning to the water outlet pipe 1 from the water return port 103 after entering the upper ball storage chamber, and the rubber ball cannot be recycled, and the partition net 34 can reduce the flow rate of the water flow in the water return chamber, so as to prevent the rubber ball from being adsorbed and blocked on the mesh of the partition net 34, so that the water flow in the ball receiving chamber cannot pass through the partition net 34 and enter the water return chamber.

The two sealing liners can ensure that the water flow in the water intake pipe 5, the serving pipe 6 and the water outlet pipe 1 cannot leak into the gap between the outer cylinder 31 and the inner cylinder 32, thereby preventing the water flow in the water intake pipe 5, the serving pipe 6 and the water outlet pipe 1 from passing through the gap between the outer cylinder 31 and the inner cylinder 32 when the bottom of the inner cylinder 32 and the bottom of the outer cylinder 31 are disassembled, thereby preventing the cooling water from leaking.
