Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning equipment technology, specifically to an integrated pressure-reading dual-pump dual-control cleaning water circuit system. Background Technology

[0002] In automated cleaning production lines in industries such as automotive, hardware, and electronics, high-pressure cleaning systems are one of the key pieces of equipment to ensure product quality and production cycle time.

[0003] Traditional cleaning water systems often suffer from the following problems in design and use: They commonly employ single-pump systems, meaning that maintenance or malfunction of the booster pump can cause the entire production line to shut down, severely impacting production efficiency and plan achievement. System pressure is easily affected by fluctuations in inlet water and nozzle wear, resulting in significant fluctuations and unstable cleaning effects, making it difficult to guarantee consistent product quality. The layout of pumps, valves, control cabinets, and other equipment is loose, occupying a large amount of workshop space, and the connecting pipelines are complex and lengthy, not only unsightly but also increasing the risk of leaks and maintenance difficulties. They lack a water resource recycling design concept, often directly discharging cleaning wastewater, wasting water resources and increasing the company's sewage disposal costs and environmental pressure. Parameters are typically set manually based on experience, making it impossible to monitor and intelligently adjust key process parameters such as water pressure and quality in real time, thus failing to adapt to the demands of flexible and intelligent production.

[0004] Therefore, the industry urgently needs a new type of cleaning water system that can overcome the above-mentioned defects and integrate dual-pump redundancy backup, precise pressure control, water resource recycling and treatment, and intelligent monitoring. Utility Model Content

[0006] To achieve the above-mentioned technical objectives, this application adopts the following technical solution: This application provides an integrated pressure-reading dual-pump dual-control cleaning water circuit system, including: Equipment platform; A booster module, comprising at least two booster pumps, wherein the at least two booster pumps are symmetrically arranged on the equipment platform and each booster pump has an outlet pipe connected to its outlet. An execution module, comprising at least two cleaning spray guns, with at least one cleaning spray gun provided on each of the water outlet pipes, and the cleaning spray guns being connected to the outlet of the booster pump; The pressure closed-loop control unit includes at least two sets of pressure valves and proportional valves. Each of the water outlet pipelines is provided with a set of pressure valves and proportional valves. The pressure valves and proportional valves are located between the booster pump and the cleaning spray gun in the corresponding water outlet pipeline. The control module is electrically connected to the booster pump, the cleaning spray gun, the pressure valve, and the proportional valve, respectively.

[0007] In some embodiments of this application, the equipment platform includes a first-layer platform, multiple support columns, connecting columns, and a second-layer platform. The first-layer platform is formed by multiple profiles overlapping each other, and the central area has a hollow structure. The multiple support columns are fixed to the first-layer platform and extend vertically downward to support the ground. One end of the connecting column is connected to the support column, and the other end passes through the hollow structure and extends upward.

Both the two-position two-way solenoid valve and the pressure sensor are electrically connected to the control module.

[0011] In some embodiments of this application, the outlet end of the proportional valve is detachably connected to at least one of the cleaning spray guns in the corresponding outlet pipeline via a fixture connector.

[0013] In some embodiments of this application, a water quality monitoring unit is also included, wherein the probe of the water quality monitoring unit is disposed in the pipeline downstream of the outlet of the water collection tank.

[0014] In some embodiments of this application, the water recycling module further includes a multi-stage physical pretreatment unit, which is integrated into the outlet of the phosphating drainage tank. The pretreatment unit includes a coarse filter, a cyclone sedimentation device, and an oil-water separator arranged in sequence, which are used to intercept large particulate impurities, separate suspended solids, and remove floating oil, respectively.

[0015] In some embodiments of this application, a leakage detection unit is also included. The leakage detection unit includes a first flow meter and a second flow meter. The first flow meter and the second flow meter are respectively installed at the inlet of any of the booster pumps and at the outlet of the proportional valve in the outlet pipeline, and are both electrically connected to the control module.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Those skilled in the art will understand that, in this specification, the term "comprising" is an open-ended expression, meaning that the stated feature is present but other features are excluded. Directional terms such as "upper," "lower," "left," and "right" refer to exemplary directions based on the accompanying drawings. Features specified as "first" or "second" implicitly include one or more of that feature. Singular expressions can also be used in plural forms. "Multiple" means two or more. The terms "installed," "connected," and "linked" can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection via an intermediate medium, and it can be a connection within two components. Furthermore, "linked" can include wireless connections.

[0021] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose an integrated pressure-reading dual-pump dual-control cleaning water circuit system to solve the technical problems of low reliability, low stability, unreasonable layout, resource waste and low level of intelligence in the existing technology.

[0022] To achieve the above-mentioned technical objectives, this application adopts the following technical solution: Reference Figures 1-4 This embodiment provides an integrated pressure-reading dual-pump dual-control cleaning water system, including: a device platform 1; a booster module, which includes two booster pumps 2 symmetrically arranged on the device platform 1, and each booster pump 2 has an outlet connected to an outlet pipe; an execution module, which includes a cleaning spray gun 3 connected to the outlet pipe of the booster pump 2, and each outlet pipe is provided with at least one cleaning spray gun 3; a control module, which is electrically connected to the booster pump 2 and the cleaning spray gun 3 respectively; and a pressure closed-loop control unit. The pressure closed-loop control unit includes a pressure valve 4 and a proportional valve 5 disposed on the pipe between the booster pump 2 and the cleaning spray gun 3, both of which are electrically connected to the control module, and each outlet pipe is provided with a set of pressure valve 4 and proportional valve 5.

[0023] Working Principle: After system startup, the control module controls the booster pump 2 to operate, directing high-pressure water to the cleaning spray gun 3. The pressure valve 4 continuously monitors the pipeline pressure before entering the proportional valve 5 and feeds back this pressure signal (e.g., a 4-20mA current signal) to the control module (e.g., a PLC). The control module internally runs a PID control algorithm, comparing this feedback pressure value with a preset target pressure value and calculating the deviation. Based on the deviation, the control module outputs a control signal to the proportional valve 5, adjusting its valve opening. If the feedback pressure is lower than the set value, the opening of the proportional valve 5 is increased; if it is higher than the set value, the opening is decreased, thus forming a dynamic, fast-response pressure closed-loop control. This ensures that the pressure ultimately delivered to the cleaning spray gun 3 remains stable near the set value, guaranteeing a consistent cleaning effect.

[0024] This embodiment establishes a high reliability and stability foundation for the system by combining a symmetrical dual-pump setup with a pressure closed-loop control unit, ensuring continuous production and consistent cleaning quality.

[0025] The structure of equipment platform 1 is defined. (Refer to...) Figure 1 The equipment platform 1 includes a first-level platform 101, multiple support columns 102, a connecting column 103, and a second-level platform 104. The first-level platform 101 is constructed from multiple interlocking industrial aluminum profiles, with a central openwork structure 105. Multiple support columns 102 (typically four) are fixed to the four corners of the first-level platform 101 and extend vertically downwards to stably support the entire platform on the ground. One end of the connecting column 103 is connected to the support column 102 or the frame of the first-level platform 101 via a profile connector, while the other end passes through the openwork structure 105 and extends upwards. The second-level platform 104 is horizontally positioned above the connecting column 103 and is used to install the control module and waterproof junction box. Protective shells are installed on the outer sides of both the first-level platform 101 and the second-level platform 104.

[0026] This unique double-layer three-dimensional platform structure ingeniously achieves the physical separation of the water circuit execution unit (located on the first floor) and the electrical control unit (located on the second floor), fundamentally eliminating the risk of damage to expensive electrical components due to water circuit leakage and improving the safety of the system; at the same time, the three-dimensional layout greatly saves floor space and makes the overall structure compact and stable.

[0027] The layout of the booster pumps 2 is further clarified. Two booster pumps 2 are arranged around the perforated structure 105 of the platform 101, and the two booster pumps 2 are centrally symmetrical. This layout allows the connecting column 103 to pass smoothly through the central gap between the two booster pumps 2. Specifically, the motor and pump head portions of each booster pump 2 have an approximately L-shaped top view. The long sides of the two pumps' L-shapes can be placed parallel to the edge of the perforated structure 105, while the short sides are opposite or back-to-back, forming a compact and symmetrical layout.

[0028] The centrally symmetrical, wraparound layout not only stabilizes the center of gravity of the entire equipment but also ensures that the pipe lengths from the outlets of the two booster pumps 2 to the junction of the main pipelines are basically the same, which helps to balance pressure and ensure smooth switching. At the same time, the design of the connecting column 103 in the central area makes full use of space, allowing maintenance personnel to easily access the pump body from all sides for maintenance.

[0029] The system also includes a water supply tank 6. Tank 6 is preferably made of SUS304 stainless steel, which is corrosion-resistant. The outlet of tank 6 is connected to the inlets of two booster pumps 2 via pipes. Inside tank 6 are installed a level gauge 601 (for visually displaying the water level) and a float sensor 602. Both level gauge 601 and float sensor 602 are electrically connected to the control module. When float sensor 602 detects that the water level is below the lower limit, it sends a signal to the control module, which then opens the inlet solenoid valve connected to the external water source to replenish water until the water level reaches the upper limit, achieving fully automatic water replenishment.

[0030] By adding an automatic water tank 6, unmanned management of the system's water source is achieved, ensuring that the booster pump 2 always has a stable water supply, effectively avoiding damage such as pump dry running and cavitation caused by water shortage, and ensuring the long-term stable operation of the system.

[0031] The piping system also includes a two-position two-way solenoid valve 7 and a pressure sensor 8. Each outlet pipe is equipped with a set of the two-position two-way solenoid valve 7 and the pressure sensor 8. Specifically, the two-position two-way solenoid valve 7 is located on the main pipe between the outlet of the booster pump 2 and the pressure sensor 8, preferably near the cleaning station (such as the robot base). The pressure sensor 8 is installed after the two-position two-way solenoid valve 7 and before the proportional valve 5. Both the two-position two-way solenoid valve 7 and the pressure sensor 8 are electrically connected to the control module. The solenoid valve acts as the main switch for the water circuit, receiving start and stop commands from the control module or external equipment (such as the cleaning robot) to achieve rapid on / off switching of the water circuit.

[0032] The newly added two-position two-way solenoid valve 7, as a fast-acting element, can accurately respond to the cycle signal of the automated production line and realize the instantaneous start and stop of the cleaning action; while the specific installation position of the pressure sensor 8 can ensure that it detects the real pressure after passing through the main switch and before entering the pressure regulating unit, eliminating the interference of valve switching on the pressure reading and providing a more accurate feedback signal for subsequent closed-loop control.

[0033] The outlet of the proportional valve 5 is detachably connected to at least one cleaning spray gun 3 in the corresponding outlet pipeline via a fixture connector 12. The fixture connector 12 can be a standard form such as a quick-connect connector, flange connector, or threaded connector.

[0034] The use of a detachable fixture connector 12 allows operators to quickly change cleaning spray guns 3 of different types, spray angles, or flow rates according to the cleaning needs of different workpieces without the need for complex tools, greatly enhancing the system's process adaptability and operational flexibility.

[0035] The system also includes a water recovery module. This module includes a collection tank 9 positioned directly below the cleaning spray gun 3, and a phosphating drainage tank 10 for centralized wastewater treatment. The collection tank 9 collects all wastewater and splashing liquid generated during the cleaning process. The outlet of the collection tank 9 is connected to the phosphating drainage tank 10 via a pipe. In some production line layouts, the outlet of the collection tank 9 may first merge with wastewater pipes from other washing processes (such as the outlet of the washing tank 11) before flowing into the phosphating drainage tank 10.

[0036] By setting up a water recycling module, the cleaning wastewater is effectively collected and guided, avoiding direct flow of wastewater to the ground that could cause environmental pollution and safety hazards in the workshop. It also creates the necessary conditions for subsequent centralized treatment, purification and recycling of wastewater, reflecting the green and environmentally friendly design concept.

[0037] The system also includes a water quality monitoring unit. The probe of this unit is located in the downstream pipe of the outlet of the collection tank 9, or directly at the inlet of the phosphating drainage tank 10. This unit can monitor key water quality indicators of the wastewater in real time, such as COD (chemical oxygen demand), ammonia nitrogen, and SS (suspended solids), and transmit the monitoring data to the control module or the plant's water treatment monitoring system.

[0038] It enables online, real-time monitoring of wastewater quality, replacing traditional manual sampling and testing. This allows managers to grasp the sewage discharge status immediately and provides real-time data support for the precise control of subsequent water treatment processes (such as reagent dosage and treatment time), thereby improving water treatment efficiency and effectiveness.

[0039] The water recycling module also includes a multi-stage physical pretreatment unit. This unit is integrated at the outlet of the phosphating drainage tank 10, meaning the wastewater passes through this unit before being discharged into the final municipal sewer network or advanced treatment facilities. This pretreatment unit includes a coarse filter, a cyclone settler, and an oil-water separator arranged sequentially. As the wastewater flows through, the coarse filter first intercepts larger solid particles (such as metal shavings and burrs), then it enters the cyclone settler where centrifugal force separates denser suspended solids, and finally, the oil-water separator removes surface oil.

[0040] Integrating local pretreatment units at wastewater discharge outlets can effectively reduce the content of major pollutants in discharged wastewater, alleviate the load on centralized wastewater treatment plants in factories, and in some cases, the pretreated water quality can even meet the standards for reuse in non-core cleaning processes, further improving the recycling rate of water resources.

[0041] The system also includes a leak detection unit. This leak detection unit comprises a first flow meter located at the main inlet of the booster module (i.e., after the outlet of water tank 6) and a second flow meter located at the main outlet of the proportional valve 5 (i.e., before fixture connector 12). Both flow meters are electrically connected to the control module. When the system is running stably, the control module records the readings of the two flow meters and continuously compares the difference between them during subsequent operation.

[0042] By comparing the inlet and outlet water flow rates in real time, it can detect minute leaks in the pipeline system with extremely high sensitivity (manifested as inlet water flow rate being greater than outlet water flow rate), and promptly issue alarms or execute shutdowns, effectively avoiding large amounts of water waste, equipment immersion damage, and safety accidents such as slippery ground caused by aging and broken pipes and joints.

[0043] The system also includes a predictive maintenance unit. This unit comprises vibration and temperature sensors mounted on the pump bodies of the two booster pumps 2, respectively, as well as a fault prediction algorithm module in the control module for analyzing vibration and temperature data. The control module continuously acquires and records the vibration spectrum from the vibration sensors and the real-time temperature from the temperature sensors.

[0044] This has enabled a shift from reactive maintenance to proactive predictive maintenance. When the system detects that the amplitude of a specific pump frequency (such as the bearing damage frequency) exceeds the limit, or that the temperature rises abnormally under the same load, it can provide early warning of potential faults and automatically switch to the backup pump, thereby avoiding huge losses to production caused by sudden shutdowns.

[0045] The control module controls the motor speeds of the two booster pumps 2 separately via frequency converters. The pressure control strategy of the control module has been upgraded to: based on the feedback from the pressure valve 4, the pressure is first coarsely adjusted by regulating the speed of the booster pumps 2, and then finely adjusted by finely regulating the opening of the proportional valve 5.

[0046] By introducing variable frequency speed control, efficient regulation of pressure and flow is achieved from the energy source. Compared with the method of simply relying on proportional valve 5 for throttling and pressure reduction, this coordinated control strategy of "variable frequency coarse adjustment + proportional valve 5 fine adjustment" can significantly reduce system energy consumption while meeting the requirements of precise pressure control. The energy-saving effect is particularly significant under the condition of large pressure demand changes, and it can also effectively reduce the wear of proportional valve 5 and extend its service life.

[0047] The system also includes a cleaning recipe management unit. This unit includes a barcode / QR code scanner and a memory connected to the control module. The memory contains pre-stored cleaning parameter recipes (such as target pressure, flow rate, dual-pump operating mode, cleaning duration, etc.) for different product models.

[0048] It achieves intelligent switching of cleaning operations with a "one item, one code" system. By scanning the identification code on the workpiece or pallet, the system automatically calls up the optimal process parameters, completely eliminating the possibility of errors in manual settings. This ensures a high degree of consistency in cleaning processes and quality traceability for different batches and types of products, and is a key link in realizing Industry 4.0 flexible manufacturing.

[0049] The system also includes a safety interlock unit. This unit includes a safety light curtain or safety door switch positioned around the working area of ​​the cleaning spray gun 3 and connected to the control module. When intrusion of personnel or objects into the working area is detected, the control module immediately forces the 2-position 2-way solenoid valve 7 to close and depressurize the booster pump 2.

[0050] The high-pressure water system is deeply integrated with regional safety protection. In the event of dangerous situations such as accidental intrusion, the system can cut off the high-pressure source and quickly depressurize within milliseconds, maximizing the personal safety of operators and maintenance personnel and meeting the highest safety standards of modern industrial production.

[0051] The control module installed on the second-layer platform 104 integrates an industrial Ethernet or wireless communication module and supports standard industrial communication protocols such as OPCUA and Profinet.

[0052] This transforms the cleaning system from an isolated information island into a smart terminal within the factory's Industrial Internet of Things (IIoT). All system operating status, pressure data, water quality data, energy consumption, and alarm information can be uploaded to the factory's Supervisory Control and Data Acquisition (SCADA) system or Manufacturing Execution System (MES), providing production managers with powerful tools for remote monitoring, data analysis, energy efficiency management, and decision support.

[0053] An active thermal management unit is installed in the junction box or control cabinet on the second-level platform 104, which is used to install electrical components. This unit includes a temperature sensor and a cooling fan or a small semiconductor refrigeration chip that is linked to the control module.

[0054] By actively controlling the internal temperature of the electrical cabinet, it ensures that precision electronic components such as controllers and frequency converters always operate within a suitable temperature range. Especially in high-temperature or enclosed production workshop environments during summer, it can effectively prevent components from malfunctioning or degrading due to overheating, thereby significantly improving the electrical reliability and long-term stability of the entire system.

[0055] The control module has a built-in intelligent dual-pump control logic, which includes at least the following: a one-in-one standby mode, where one pump is working and the other is in hot standby mode, automatically switching in case of failure; a dual-pump parallel boosting mode, where the two pumps work together when ultra-high flow or ultra-high pressure is required; and a timed rotation mode, where the two pumps automatically switch between primary and standby roles according to a preset time (e.g., every 8 hours) to balance wear.

[0056] Through an intelligent dual-pump scheduling strategy, the system can flexibly respond to different production needs and achieve fault self-healing and equipment life balance without human intervention, raising the system's operational reliability, flexibility and overall service life to a new level.

[0057] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include: High reliability: Dual pump redundancy and intelligent switching logic ensure uninterrupted production 24 / 7.

[0058] Excellent layout and high safety: The double-layer three-dimensional platform achieves physical separation of water and electricity, with a compact and stable structure that is both safe and aesthetically pleasing.

[0059] Precise control: The pressure closed-loop control and frequency conversion coordination strategy achieve high precision and high stability of cleaning pressure, ensuring product quality.

[0060] Highly intelligent integration and scalability: It integrates multiple intelligent functions such as automatic water replenishment, water quality monitoring, leak detection, predictive maintenance, formula management, safety interlock, and IoT communication, and its modular design facilitates future upgrades.

[0061] Energy saving and environmental protection: The design of the variable frequency energy-saving control and water recycling pretreatment unit embodies the concepts of green manufacturing and sustainable development.

[0062] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0063] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
