Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic cleaning devices for condensers, and more particularly to a small ball cleaning system for water-cooled condensers. Background Art
[0002] A small ball cleaning system is typically installed in the bypass of equipment such as condensers, heat exchangers, and air-cooled heat pumps. Its primary function is to clean the internal pipes of the equipment, removing debris such as scale from the pipe walls. When the small ball cleaning system is in operation, it releases small balls into the main pipes. These balls are then carried along by the circulating water in the main pipes and into the internal walls of the equipment. The water pressure then circulates the small balls through the pipes, cleaning the interior of the pipes.
[0003] Existing ball cleaning systems are often used as a bypass for equipment cleaning, with a separate circulation control system, connected to the main system but acting as an independent auxiliary system. Because of this independence and auxiliary nature, they are often overlooked when it comes to controlling investment costs, and are even considered non-essential. As a result, after long-term operation, the internal walls of the pipes can become severely scaled, leading to low system energy efficiency.
[0004] For example, the invention patent with publication number CN209445838U discloses an automatic cleaning device for cleaning the heat exchange pipes of condensers. The device uses circulating balls to clean the inner wall of the pipe. A ball separation device is connected to the outlet pipe of the condenser, and a water ejector is installed on the inlet pipe of the condenser. The side suction port of the water ejector is connected to the ball separation device through a bypass pipe. Since the cleaning system in the comparative document adds a water ejector and multiple valves, the system failure rate is also increased due to the additional circulating pumps and valves. Operation and maintenance personnel are required to clean the main equipment on time. Due to negligence of operation and maintenance personnel, the ball cleaning system is shelved and no one uses or maintains it for a long time.
[0005] Now a water-cooled condenser ball system with automatic pressure regulation, speed change and energy saving and cleaning is needed to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to provide a water-cooled condenser ball cleaning system to overcome the above-mentioned defects in the prior art.
[0007] The technical solution for achieving the purpose of the utility model is: a water-cooled condenser ball cleaning system, comprising a condenser, a water inlet pipe, a water outlet pipe and a ball circulation pipe, the water inlet pipe and the water outlet pipe being connected to the condenser respectively, one end of the ball circulation pipe being connected to the water inlet pipe and the other end being connected to the water outlet pipe, a ball storage chamber being provided in the middle of the ball circulation pipe; a multi-stage supercharger being connected to the ball circulation pipe being provided in the water outlet pipe, the multi-stage supercharger automatically expanding or contracting according to the pressure of the water outlet pipe to realize automatic adjustment of the water pressure in the ball circulation pipe.
[0008] As a preferred embodiment, the multi-stage booster is provided with a pressure ring assembly, a catheter sleeve and a telescopic catheter in sequence along the water outlet direction in the water outlet pipe. The pressure ring assembly is connected to the catheter sleeve through a communicating vessel assembly. One end of the telescopic catheter is fixedly connected to the catheter sleeve, and the other end is connected to the pipe mouth of the ball circulation pipe. The pressure ring assembly drives the catheter sleeve to move axially along the water outlet pipe according to the water pressure of the water outlet pipe, and further drives the telescopic catheter to expand and contract.
[0009] As a preferred embodiment, the pressure ring assembly includes a pressure ring and no less than two springs, one end of the spring is fixed to the inner wall of the water outlet pipe, and the other end is fixed to the pressure ring.
[0010] As a preferred embodiment, the telescopic catheter is composed of no less than two sections of sub-sleeves connected layer by layer, and each sub-sleeve is provided with two openings with a larger radius and a smaller radius along the axial direction. When the telescopic catheter is expanded along the axial direction, the radius of the inner wall of the telescopic catheter gradually decreases in the direction from the catheter collar to the pipe opening of the ball circulation pipe.
[0011] As a preferred embodiment, the communicating vessel assembly includes a first transmission rod, a communicating vessel and a second transmission rod, one end of the first transmission rod is fixedly connected to the pressure ring, and the other end is slidably connected to a communicating tube of the communicating vessel, and one end of the second transmission rod is fixedly connected to the catheter collar, and the other end is slidably connected to another communicating tube of the communicating vessel.

[0015] (2) The utility model controls the expansion and contraction of the telescopic tube in the pressure ring assembly according to the water pressure of the outlet pipe, thereby controlling the pressure of the ball circulation pipe. The structure is simple. When it is necessary to clean the scale in the pipe, it is only necessary to increase the pressure in the water inlet pipe to achieve the purpose of pressurizing the ball cleaning system.

[0035] (Example 1)
[0036] Figures 1 to 4 A water-cooled condenser ball cleaning system includes a condenser 1, a water inlet pipe 2, a water outlet pipe 3 and a ball circulation pipe 4. The water inlet pipe 2 and the water outlet pipe 3 are respectively connected to the condenser 1. One end of the ball circulation pipe 4 is connected to the water inlet pipe 2 and the other end is connected to the water outlet pipe 3. A storage chamber 4-1 for balls 5 is provided in the middle of the ball circulation pipe 4; a multi-stage supercharger 6 connected to the ball circulation pipe 4 is provided in the water outlet pipe 3.
[0037] The multi-stage booster 6 includes a pressure ring assembly 6-1, a conduit collar 6-2, a telescopic conduit 6-3, and a manifold assembly 6-4. The pressure ring assembly 6-1 comprises a pressure ring 6-1-1 and two springs 6-1-2. One end of the spring 6-1-2 is fixed to the inner wall of the outlet pipe 3, and the other end is fixed to the pressure ring 6-1-1. A through hole is provided in the center of the pressure ring 6-1-1 to ensure the normal flow of water through the outlet pipe 3. The inner diameter of the pressure ring 6-1-1 is smaller than that of the outlet pipe 3. The two springs 6-1-2 are symmetrically distributed around the pressure ring 6-1-1, ensuring that the pressure ring 6-1-1 is evenly stressed and can move axially along the outlet pipe 3.
[0038] like Figure 5 As shown, the catheter ring 6-2 is composed of two circular rings with a larger radius and a smaller radius, and the two circular rings are fixedly connected by four brackets.
[0039] like Figure 6 and Figure 7 As shown, the telescopic conduit 6-3 is constructed from three sub-tubes, each of which is nested layer by layer. Each sub-tube has two openings, one with a larger radius and one with a smaller radius, along the axial direction. As the telescopic conduit 6-3 is axially expanded, the radius of the inner wall of the telescopic conduit 6-3 gradually decreases from the conduit collar 6-2 toward the orifice of the ball circulation conduit 4. The outermost sub-tube of the telescopic conduit 6-3 has a larger opening fixedly connected to the conduit collar 6-2, and its other end communicates with the orifice of the ball circulation conduit 4.
[0040] The inner ring of the catheter collar 6-2 is fixedly connected to the opening with the larger radius of the outermost sub-sleeve of the telescopic catheter 6-3 and the radii of the two are consistent. The outer ring of the catheter collar 6-2 is consistent with the radius of the pressure ring 6-1-1.
[0041] The manifold assembly 6-4 includes a first transmission rod 6-4-1, a manifold 6-4-2, and a second transmission rod 6-4-3. One end of the first transmission rod 6-4-1 is fixedly connected to the pressure ring 6-1-1, and the other end is slidably connected to a connecting tube of the manifold 6-4-2. The second transmission rod 6-4-3 has one end fixedly connected to the outer ring of the conduit collar 6-2, and the other end is slidably connected to the other connecting tube of the manifold 6-4-2. The pressure ring assembly 6-1, conduit collar 6-2, and telescopic conduit 6-3 are arranged sequentially along the water outlet direction of the outlet pipe 3.
[0042] It also includes a ball filter 7, which is arranged on the inner side of the telescopic guide tube 6-3. One end of the ball filter 7 is fixed around the pipe mouth of the ball circulation pipe 4, and the other end is fixed around the inner wall of the outlet pipe 3. By setting the ball filter, the balls are prevented from flowing out of the outlet pipe, thereby reducing the loss of the balls.
[0043] When the pressure ring is under pressure, the pressure is transmitted through the transmission rod and the spring is driven to stretch; when the pressure of the pressure ring is released, the spring contracts and brings the pressure ring back to the normal position. The pressure ring can automatically adjust and reset according to the water pressure, without the need for manual adjustment and reset. The pressure ring assembly 6-1 drives the conduit collar 6-2 to move along the axial direction of the outlet pipe 3 according to the water pressure of the outlet pipe 3, and further drives the telescopic conduit 6-3 to expand and contract, and increases the pressure by increasing the flow rate entering the ball circulation pipe per unit time, forcing the balls in the storage chamber to enter the water inlet pipe. This embodiment has a simple structure. When it is necessary to clean the scale in the pipe, it is only necessary to increase the pressure in the water inlet pipe to achieve the purpose of pressurizing the ball cleaning system, and it is easy to operate.
[0044] The working principle of this embodiment is as follows:
[0045] When external circulating water enters the water inlet pipe, due to the low pressure of the external circulating pump, the circulating water flows through the condenser and toward the outlet. At this point, the circulating water pressure is insufficient to push the pressure ring, and the entire multi-stage booster is in normal operation. Most of the circulating water passes through the ball filter and flows to the outlet. A small amount of circulating water flows into the ball circulation pipe, but the water pressure is insufficient to push the balls out of the ball storage chamber.
[0046] As the external circulating pump pressure increases, the circulating water flow rate increases, and the water pressure on the pressure ring gradually increases. The pressure ring transmits this pressure via a drive rod inside the communicating vessel to a conduit collar at the other end of the drive rod. Driven by the drive rod, the conduit collar gradually rises, driving the connected telescopic conduit.
[0047] At this time, due to the expansion of the telescopic catheter, the circulating water that could originally flow to the water outlet through the small ball filter is diverted to the small ball circulation pipe, and the pressure in the small ball circulation pipe increases.
[0048] The balls in the ball storage chamber flow into the main pipe along with the increasing water flow, pass through the condenser branch pipe, return to the main pipe, and are finally guided into the ball circulation pipe by the ball filter and enter the ball storage chamber, completing the ball cleaning operation.
[0049] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
