Description

Technical Field

[0001] The present invention belongs to the technical field of condenser pipeline cleaning, and specifically provides a condenser rubber ball cleaning device. Background Art

[0002] As is well known, a condenser is a commonly used device in a heat exchange system. After being used for a period of time, scale and sludge will accumulate in the condenser pipeline, thereby reducing the heat exchange efficiency. In severe cases, it may cause blockage of the condenser pipeline. To solve this problem, it is necessary to regularly clean the condenser pipeline. Manual cleaning not only has high costs and low efficiency, but also requires shutdown and disassembly, which is very troublesome.

[0003] Currently, the most widely used rubber ball cleaning equipment on the market has the principle of passing rubber balls through the condenser pipeline to wash the dirt on the inner wall of the pipeline. However, the structures of rubber ball cleaning equipment on the market are diverse and the costs are also relatively high, which requires further improvement.

[0004] Correspondingly, there is a need in the art for a condenser rubber ball cleaning device to solve the above problems. Summary of the Invention

[0005] The present invention proposes a condenser rubber ball cleaning device to solve the above problems mentioned in the background art.

[0006] The technical solution of the present invention is realized as follows: The condenser rubber ball cleaning device includes a frame, a cylinder body and a centrifugal pump arranged on the frame. The water inlet of the centrifugal pump is connected with a first three-way valve, and the water outlet is connected with a second three-way valve. The first three-way valve includes a valve port 1, a valve port 2 and a valve port 3, and the second three-way valve includes a valve port 4, a valve port 5 and a valve port 6. The valve port 1 is connected with the water inlet of the centrifugal pump, the valve port 3 is connected with the valve port 4 through a three-way pipe, the valve port 6 is connected with the water outlet of the centrifugal pump, the remaining port of the three-way pipe is connected with the cylinder body, and a filter screen is arranged between the three-way pipe and the cylinder body. Rubber balls are arranged in the cylinder body. A ball shooting pipe is connected to the position of the cylinder body near the bottom end, and a first valve is arranged on the ball shooting pipe. A ball returning pipe is connected to the position of the cylinder body near the top end, and a second valve is arranged on the ball returning pipe. One end of the ball returning pipe away from the second valve is connected with a filter ball structure. During cleaning, water flows through the valve port 2 and the valve port 1 and is sucked into the centrifugal pump, and is pumped into the cylinder body by the centrifugal pump through the valve port 6, the valve port 4 and the connection between the three-way pipe and the cylinder body. The water flow shoots the rubber balls into the condenser pipeline through the ball shooting pipe for cleaning. When recovering the rubber balls, the water flow enters the cylinder body through the ball returning pipe, is sucked into the centrifugal pump through the connection between the cylinder body and the three-way pipe, the valve port 3 and the valve port 1, and is pumped out by the centrifugal pump through the valve port 6 and the valve port 5. The rubber balls are intercepted in the cylinder body by the filter screen.

[0007] The technical effect of this solution is as follows: The online cleaning function of the condenser pipeline can be realized by this rubber ball cleaning device. At the same time, through the cooperation of the first three-way valve, the second three-way valve, the first valve and the second valve, only one centrifugal pump can be used to realize the launching and recovery of rubber balls. While the structure is simple, stable and efficient, the production cost is also reduced.

[0008] In the preferred technical solution of the above-mentioned condenser rubber ball cleaning device, the communication port between the cylinder body and the ball return pipe is located above the communication port between the cylinder body and the three-way pipe. The filter screen is arranged in an inverted conical shape in the cylinder body. The top edge of the filter screen is attached to and connected with the inner wall of the cylinder body, and the connection position is between the communication port between the cylinder body and the ball return pipe and the communication port between the cylinder body and the three-way pipe. An opening is provided at the bottom end of the filter screen.

[0009] The technical effect of this solution is as follows: The filter screen is set in an inverted conical shape to guide the movement of the rubber balls, which is beneficial for the rubber balls to impact the ball shooting pipe under the impact of water flow; the connection position of the filter screen neither affects the entry of the rubber balls from the ball return pipe into the cylinder body nor forms a blockage for the rubber balls to enter the three-way pipe, which is beneficial for the smooth recovery of the rubber balls.

[0010] In the preferred technical solution of the above-mentioned condenser rubber ball cleaning device, both the first three-way valve and the second three-way valve are electric three-way valves, the first valve is an electric butterfly valve, and the second valve is a one-way valve. When the medium flows from the ball return pipe into the cylinder body, the one-way valve opens.

[0011] The technical effect of this solution is as follows: The electric control of the valves is realized, which improves the intelligence and convenience of use of this device.

[0012] In the preferred technical solution of the above-mentioned condenser rubber ball cleaning device, an opening is provided at the top of the cylinder body, and a cover body is provided at the opening. First convex edges and second convex edges are respectively extended along the circumferences of the opening of the cylinder body and the cover body. Grooves corresponding up and down are provided at intervals in the circumferences of the first convex edge and the second convex edge. A screw rod is hinged at the groove of the first convex edge. When the cylinder body and the cover body are connected, the screw rod is located in the grooves of the first convex edge and the second convex edge and extends above the second convex edge. A locking head is threadedly connected to the screw rod, a handle is provided on the locking head, and the locking head abuts against the upper surface of the second convex edge.

[0013] The technical effect of this solution is as follows: An opening is provided at the top of the cylinder body, which is beneficial for cleaning and replacing the rubber balls and the filter screen in the cylinder body, ensuring the normal operation of this device and extending its service life; the cover body and the cylinder body are tightly connected by the screw rod and the locking head, preventing water flow from overflowing from the top of the cylinder body and ensuring the tightness inside the cylinder body.

[0014] In the preferred technical solution of the above-mentioned condenser rubber ball cleaning device, the filter ball structure includes an outer tube and an inner tube disposed inside the outer tube. The outer tube includes a main body tube and reduced-diameter tubes extending from both ends of the main body tube. Both ends of the inner tube are connected to the two reduced-diameter tubes. One end of the outer tube is connected to the ball return pipe, and the other end is used to be connected to the condenser water outlet pipe. A sewage discharge port is provided on the outer tube, and filter ball holes are provided on the inner tube.

[0015] The technical effect of this solution is that after the rubber balls clean the condenser pipes, they enter the filter ball structure. The sewage is discharged from the filter ball holes of the inner tube to the outer tube and discharged through the sewage discharge port. The rubber balls are intercepted inside the inner tube and wait to be recycled into the cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Specific embodiments of the condenser rubber ball cleaning device of the present invention are as follows: Figure 1 As shown in the figure, the condenser rubber ball cleaning device includes a frame 10, a cylinder 1 and a centrifugal pump 8 provided on the frame 10. The cylinder 1 and the centrifugal pump 8 are bolted to the frame 10.

[0023] The water inlet of the centrifugal pump 8 is connected with a three-way valve I 9, and the water outlet is connected with a three-way valve II 6. The three-way valve I 9 includes a valve port I 901, a valve port II 902 and a valve port III 903. The three-way valve II 6 includes a valve port IV 601, a valve port V 602 and a valve port VI 603. The three-way valve I 9 is connected to the water inlet of the centrifugal pump 8 through the valve port I 901, and the three-way valve II 6 is connected to the water outlet of the centrifugal pump 8 through the valve port VI 603. The valve port III 903 of the three-way valve I 9 is connected to the valve port IV 601 of the three-way valve II 6 through a three-way pipe, and the remaining port of the three-way pipe is connected to the cylinder 1, and a filter screen 11 is provided between the three-way pipe and the cylinder 1. To adapt to the distance between the three-way valve I 9 and the three-way valve II 6, a connecting pipe 7 is connected between the valve port VI 603 of the three-way valve II 6 and the water outlet of the centrifugal pump 8. The valve port II 902 of the three-way valve I 9 is connected to the water inlet pipe of the condenser to pump water from the water inlet pipe. Among them, both the three-way valve I 9 and the three-way valve II 6 are electric three-way valves.

[0024] Rubber balls 12 are arranged in the cylinder 1. A ball shooting pipe 5 is connected to the position of the cylinder 1 near the bottom end. A first valve 4 is provided on the ball shooting pipe 5, and the end of the ball shooting pipe 5 away from the first valve 4 is connected to the water inlet pipe of the condenser, and the connection position is downstream of the connection position between the three-way valve I 9 and the water inlet pipe. A ball returning pipe 3 is connected to the position of the cylinder 1 near the top end. A second valve 2 is provided on the ball returning pipe 3, and the end of the ball returning pipe 3 away from the second valve 2 is connected with a filter ball structure 14. The ball returning pipe 3 is connected to the water outlet pipe of the condenser. Among them, the first valve 4 is an electric butterfly valve, and the second valve 2 is a one-way valve. When the medium flows from the ball returning pipe 3 into the cylinder 1, the one-way valve opens.

[0025] When the condenser pipeline needs to be cleaned, by controlling the three-way valve I 9, the valve port I 901 and the valve port II 902 are made to form a passage. By controlling the three-way valve II 6, the valve port IV 601 and the valve port VI 603 are made to form a passage. By opening the first valve 4, the valve port IV 601, the cylinder 1 and the ball shooting pipe 5 are made to form a passage.

[0026] Start the centrifugal pump 8. Part of the water flow in the condenser inlet pipe enters from the valve port two 902, and after passing through the valve port one 901, the connecting pipe 7, the valve port six 603, the valve port four 601 and the cylinder body 1, the rubber balls 12 are launched from the ball shooting pipe 5 into the inlet pipe, and enter the condenser pipe with the inlet pipe for cleaning work.

[0027] After the condenser cleaning work is completed, it is necessary to recycle the rubber balls 12 into the rubber ball cleaning device. By controlling the three-way valve one 9, the valve port one 901 and the valve port three 903 form a passage. By controlling the three-way valve two 6, the valve port five 602 and the valve port six 603 form a passage. By closing the first valve 4, the valve port three 903, the cylinder body 1 and the ball return pipe 3 form a passage.

[0028] Start the centrifugal pump 8. The water flow in the condenser outlet pipe carries the rubber balls 12 into the cylinder body 1 from the ball return pipe 3, flows out after passing through the cylinder body 1, the valve port three 903, the valve port one 901, the connecting pipe 7, the valve port six 603 and the valve port five 602, and the rubber balls 12 are intercepted in the cylinder body 1 by the filter screen 11 at the connection of the cylinder body 1 and the three-way pipe.

[0029] Through this rubber ball cleaning device, the online cleaning function of the condenser pipe can be realized. At the same time, through the cooperation of the three-way valve one 9, the three-way valve two 6, the first valve 4 and the second valve 2, only one centrifugal pump 8 can realize the launching and recycling of the rubber balls 12. While the structure is simple, stable and efficient, the production cost is also reduced.

[0030] Among them, the connection port of the cylinder body 1 and the ball return pipe 3 is located above the connection port of the cylinder body 1 and the three-way pipe.

The bottom end of the filter screen 11 is provided with an opening.

[0031] The filter screen 11 arranged in an inverted cone shape guides the movement of the rubber balls 12, which is beneficial for the rubber balls 12 to impact towards the ball shooting pipe 5 under the impact of the water flow; the connection position of the filter screen 11 neither affects the rubber balls 12 entering the cylinder body 1 from the ball return pipe 3 nor forms an obstruction to the rubber balls 12 entering the three-way pipe, which is beneficial for the smooth recycling of the rubber balls 12.

[0032] As Figure 2 shown, the filter ball structure 14 includes an outer pipe 15 and an inner pipe 16 arranged in the outer pipe 15. The outer pipe 15 includes a main pipe and reduced-diameter pipes 151 extending from both ends of the main pipe. Both ends of the inner pipe 16 are connected to the two reduced-diameter pipes 151. One end of the outer pipe 15 is connected to the ball return pipe 3, and the other end is connected to the condenser outlet pipe. A sewage discharge port 152 is opened on the outer pipe 15, and filter ball holes 161 are opened on the inner pipe 16.

[0033] After the rubber balls 12 clean the condenser pipes, they enter the filter ball structure 14 through the water outlet pipe. The sewage is discharged from the filter ball holes 161 of the inner pipe 16 to the outer pipe 15 and discharged through the sewage outlet 152. The rubber balls 12 are intercepted inside the inner pipe 16 and wait to be recycled into the cylinder body 1.

Hinge ears are provided on both sides of the bottom of the first convex edge at the grooves. A screw rod is hinged between the hinge ears. A locking head is threadedly connected to the screw rod, and a handle is installed on the locking head.

[0035] When the cylinder body 1 and the cover body 13 are connected, the grooves on the first convex edge and the second convex edge are aligned up and down, the screw rod is rotated to be located in the grooves of the first convex edge and the second convex edge, and the locking head is screwed into the part of the screw rod above the second convex edge, so that the locking head tightly abuts against the upper surface of the second convex edge, avoiding water overflowing from the top of the cylinder body 1 and ensuring the airtightness inside the cylinder body 1.

[0036] In the above embodiment, the first three-way valve and the second three-way valve are electric three-way valves, the first valve is an electric butterfly valve, and the second valve is a one-way valve. In other embodiments, the first three-way valve and the second three-way valve can also be set as manual three-way valves, the first valve can also be set as a manual valve or a solenoid valve, and the second valve can also be set as an electric valve.

[0037] In the above embodiment, the filter screen is arranged in an inverted conical shape inside the cylinder body.

The inner pipe is provided with filter ball holes, and the outer pipe is provided with a sewage outlet. In other embodiments, the filter ball structure can also be set to include a pipe body, and the pipe body is provided with sewage holes, and the aperture of the sewage holes is smaller than the diameter of the rubber balls.
