Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning equipment, specifically a high-efficiency cleaning device for pipeline operations. Background Technology

[0002] In the fields of industrial production and facility maintenance, regular and efficient cleaning of various piping systems (such as central air conditioning refrigerant pipes, industrial process pipes, heat exchanger networks, etc.) is a key process to ensure efficient system operation and extend service life. Traditional pipe cleaning methods usually rely on a temporary combination of various equipment, such as external water sources, independent heating equipment, water pumps, and chemical agent dosing devices.

[0003] A search revealed a Chinese patent with publication number CN209238617U, which discloses an automatic cleaning device for cleaning equipment pipelines. This automatic cleaning device includes at least three liquid storage tanks and a pipeline switching mechanism. The pipeline switching mechanism includes a fixed base, at least three sets of fixed pipe connections corresponding to the liquid storage tanks, movable supports, movable pipe connections, and a drive assembly for moving the movable supports. This invention uses the pipeline switching mechanism in the automatic cleaning device to switch between movable and fixed pipe connections, allowing the spray gun to connect to each liquid storage tank. When connected to a liquid storage tank containing cleaning fluid, the spray gun and pipelines are cleaned, ensuring that the spray gun and pipelines in the cleaning equipment meet the standards for changing the cleaning fluid. Connecting the spray gun to a liquid storage tank containing new cleaning fluid allows the new fluid to be sprayed from the spray gun to clean the object to be cleaned. This automatic cleaning device makes the method of changing the cleaning fluid in the cleaning equipment simple to operate and highly efficient. However, existing technologies cannot achieve precise control and automatic mixing of cleaning fluid dosage, which often leads to problems such as unstable agent concentration and uneven mixing during actual operation, affecting the cleaning effect and potentially causing agent waste. At the same time, existing equipment is mostly a split structure with low integration, cumbersome on-site layout, and operation relies on manual experience, which cannot achieve integrated and intelligent cleaning process control, thus reducing operation efficiency and equipment reliability.

[0004] Therefore, based on the above-mentioned search and combined with existing technologies, a high-efficiency cleaning device for pipeline operations is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency cleaning device for pipeline operations, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency cleaning device for pipeline operations includes: a support frame with four casters on its top surface; an electrical distribution box fixedly installed on the rear side wall of the support frame; a water tank fixedly installed on the inner wall of the support frame; a mating interface box fixedly installed on the inner wall of the support frame in front of the water tank; a water pump located between the water tank and the mating interface box; a display fixedly installed on the front side wall of the mating interface box; and a control system integrated inside the display; and a mixing component mounted on the water tank.

[0007] Preferably, the mixing component includes: a water inlet pipe, which is fixedly installed on one side of the water tank, and a turbine flow meter is installed inside the water inlet pipe, which is used to fill the water tank with water.

[0009] Preferably, the sealing element includes: a limiting rod, which is fixedly installed on the inner wall of the sealing groove, and a sealing plate is slidably installed on the outer surface of the limiting rod, the sealing plate sliding in the sealing groove.

[0010] Preferably, the sealing element further includes a spring, which is disposed on the outer surface of the limiting rod, with one end connected to the side wall of the sealing groove and the other end connected to the side wall of the sealing plate. Multiple rectangular electromagnets are fixedly installed on the side wall of the sealing groove, and the rectangular electromagnets can attract the sealing plate when energized.

[0011] Preferably, the bottom surface of the sealing groove is provided with a through groove, and the bottom surface of the storage chamber is provided with a rectangular groove. The chemical liquid in the storage chamber flows into the water tank through the rectangular groove and the through groove and mixes with the water in the water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By incorporating a vacuum-maintaining component, the sealing plate, rectangular electromagnet, and spring work together to achieve precise opening and closing control of the chemical cleaning solution dosing channel. This ensures that the agent is released only when needed, preventing premature leakage or overdosing and improving the accuracy of the mixing ratio and the consistency of the cleaning effect. Simultaneously, the vacuum-maintaining component automatically resets and seals in the event of a power outage, enhancing the system's safety and reliability. This makes it particularly suitable for unattended or highly automated cleaning operations, effectively reducing the frequency of manual intervention and operational risks.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In one typical implementation of this application, please refer to Figures 1-5 As shown, a high-efficiency cleaning device for pipeline operations includes a bracket 1, casters 2, a power distribution box 3, a water tank 4, a docking interface box 5, a water pump 6, a display 7, and a mixing component disposed on the water tank 4.

[0017] The support frame 1, serving as the main load-bearing and integrated framework of the equipment, is constructed from welded square tubing and treated with rust-proof paint, possessing sufficient structural strength and stability. Four casters 2 are installed at the four corners of the top surface of the support frame 1, with at least two of them equipped with foot brakes to facilitate flexible movement of the equipment within the work area and reliable fixation after positioning. A distribution box 3 is bolted to the rear wall of the support frame 1, integrating electrical components such as a main power switch, circuit breaker, contactor, and PLC controller (which can be integrated into the control system of the display 7), providing the core for power distribution and control of the entire equipment. The door lock of the distribution box 3 uses a key switch, strictly complying with safety operating procedures.

[0018] A water tank 4 is fixedly installed in the lower part of the inner cavity of the bracket 1 for storing cleaning water. The water tank 4 is welded from stainless steel and has a water level sensor (not shown in the figure) inside. For example, three float switches of different heights are used to monitor the high, medium and low water levels and display them on the display 7 as indicator lights (such as "all three green lights are on" to indicate that the water level is sufficient). This design effectively prevents the water pump 6 from running dry and the heating wire from burning dry.

[0019] The water tank 4 and the mating box 5 are connected by a high-temperature and high-pressure resistant hose or metal pipe, and a water pump 6 is installed on this pipe. The water pump 6 is the core of the fluid power of this equipment, and preferably a corrosion-resistant, multi-stage high-pressure centrifugal pump. After starting, it can pressurize the liquid in the water tank 4 and pump it into the mating box 5. The front panel of the mating box 5 integrates multiple outlet valves and their corresponding quick-connect interfaces (not shown in detail in the figure) for connecting hoses to the pipeline to be cleaned. The box can also integrate circulation valves, drain valves, etc., for realizing internal circulation of the equipment and drainage after operation.

[0020] The front side wall of the interface pairing box 5 is fixedly mounted with a display 7 via a mounting bracket. This display 7 is an industrial-grade touchscreen, which integrates a control system (such as a PLC). This system integrates multiple operating modes, including manual and automatic modes, and can centrally control the start and stop of the water pump 6, the switching of the heating wire, and the on / off state of various valves. It also displays key parameters such as water level, water temperature, water pump pressure, and water flow status in real time, serving as the human-machine interface for intelligent operation and status monitoring of the entire equipment.

[0021] The mixing assembly includes an inlet pipe 8 fixedly installed on one side of the water tank 4 for filling the tank 4 with water. The inlet of the inlet pipe 8 can be equipped with a quick connector for connecting to an external water source. A turbine flow meter 9 is installed inside the inlet pipe 8 to accurately measure the total volume or instantaneous flow rate of the water injected into the water tank 4, and transmits this measurement signal (such as a pulse signal) to the control system in real time, providing a metering reference for the precise addition of subsequent chemical agents.

[0022] A cover plate 10 is bolted to the top surface of the water tank 4, and a sealing ring is provided between the cover plate 10 and the opening of the water tank 4 to ensure airtightness. A storage chamber 11 is fixedly installed on the top surface of the cover plate 10 for storing concentrated chemical cleaning solution. The storage chamber 11 can be made of transparent or semi-transparent chemical corrosion-resistant material (such as PP), and its outer wall has volume markings for easy observation of the liquid level. A sealing groove 12 is formed on the top surface of the cover plate 10, below the storage chamber 11. A rectangular groove 14 is formed on the bottom surface of the storage chamber 11, and a through groove 13 is formed on the bottom surface of the sealing groove 12. Under the action of gravity, the chemical liquid can flow from the storage chamber 11 through the rectangular groove 14 into the sealing groove 12, and finally into the water tank 4 through the through groove 13 to mix with the water in the water tank 4.

[0023] The core of the mixing assembly is a seal used to precisely control whether and when chemical liquid is added. The seal includes two limiting rods 15 fixedly mounted on the opposing inner walls of the sealing groove 12. A sealing plate 16 made of a magnetically conductive material (such as 430 stainless steel) is slidably mounted on the outer surface of the two limiting rods 15 and can slide parallel to the limiting rods 15 in the sealing groove 12, thereby opening or closing the upper opening of the through groove 13.

[0024] The seal also includes a spring 17. The spring 17 is sleeved on the outer surface of the limiting rod 15, with one end connected to the side wall of the sealing groove 12 and the other end connected to the side wall of the sealing plate 16. In the natural state (i.e., when the rectangular electromagnet 18 is de-energized), the elastic force of the spring 17 pushes the sealing plate 16 to press against the top of the through groove 13, forming a reliable seal and preventing the chemical liquid from flowing out.

[0025] Multiple rectangular electromagnets 18 are also fixedly installed on the side wall of the sealing groove 12. The electrical leads of the rectangular electromagnets 18 are connected to the control system. When the control system (which determines the need to add chemicals based on the water flow signal fed back by the turbine flow meter 9) issues a command, the rectangular electromagnets 18 are energized, generating a strong magnetic force that attracts the sealing plate 16, causing it to overcome the elastic force of the spring 17 and slide against the side wall, thereby opening the upper opening of the through groove 13 and allowing the chemical liquid to flow into the water tank 4 as needed.

[0026] Working principle: In use, the equipment is moved to the working position and fixed by the casters 2 on the top surface of the bracket 1. Then, the external water source is connected to the water inlet pipe 8, and the control system is started. Water flows through the water inlet pipe 8 into the water tank 4. The turbine flow meter 9 measures the injected water volume in real time and transmits the signal to the control system. When the water volume reaches the set value, the control system instructs the rectangular electromagnet 18 to be energized, generating magnetic force to attract the sealing plate 16 to slide along the limit rod 15 and compress the spring 17, opening the through groove 13. The chemical cleaning solution in the storage chamber 11 flows precisely into the water tank 4 under the action of gravity through the rectangular groove 14, the sealing groove 12 and the through groove 13, and mixes with the injected water in a preset ratio. After mixing, the control system starts the water pump 6 to pressurize the mixture and pump it into the matching box 5. Then, the pipeline to be cleaned is connected through the quick-connect interface to achieve efficient, precise and integrated pipeline cleaning operation. When the operation is completed or the power is cut off, the rectangular electromagnet 18 is de-energized, the spring 17 automatically resets, and the sealing plate 16 re-closes the through groove 13 to prevent chemical leakage and ensure system safety.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
