Description
Technical Field
[0001] This invention relates to the field of waterjet cutting technology, and in particular to a fully intelligent waterjet explosion-proof cutting water inlet cryogenic treatment device and system. Background Technology
[0002] The existing waterjet explosion-proof cutting water inlet cryogenic treatment device and system is a supporting cooling equipment designed specifically for high-risk cutting scenarios. Its core consists of a cryogenic chiller unit, an intelligent temperature control module, a closed-loop circulation pipeline, and explosion-proof components. Its working process is as follows: external water first passes through a multi-stage filter to remove impurities before entering the cryogenic chiller unit. Through refrigerant circulation, the water temperature is stably controlled within the 5-15℃ range. The cooled cryogenic water is then directly supplied to the cooling channel of the waterjet cutting head via an explosion-proof pipeline, simultaneously cooling the high-pressure water flow and the cutting area. The system is equipped with an intelligent linkage module that can interact in real time with the pressure and flow data of the cutting host: when the cutting load increases, the temperature control module automatically increases the cooling power to maintain a stable water temperature; simultaneously, an integrated explosion-proof sensor triggers an emergency increase in cryogenic water flow if the ambient gas concentration exceeds the standard, enhancing the cooling and explosion-proof effect. These devices are mostly enclosed in explosion-proof shells, making them suitable for flammable and explosive environments such as chemical plants and coal mines. They suppress temperature rise in the cutting area by using low temperatures, reduce heat loss in high-pressure components of the cutting head, and extend the service life of nozzles and seals. They are key supporting systems for ensuring safety and accuracy in high-risk waterjet cutting operations.
[0003] Existing cryogenic water inlet treatment devices for explosion-proof water jet cutting generally employ a room-temperature water inlet operation mode. However, the drawbacks of this method become increasingly apparent as cutting conditions intensify. When cutting hard materials or performing prolonged continuous operations, the frictional heat and material phase transformation heat generated by the high-pressure water jet impacting the workpiece surface rapidly accumulate in the cutting area, causing local temperatures to rise to over 150°C in a short time. This high temperature not only alters the microstructure of some special materials, damaging their original mechanical properties, but also causes defects such as burrs and chipping on the cut surface, failing to meet the precision requirements of specialized cutting. Simultaneously, under high temperature and pressure, the water mist generated during cutting easily carries high-temperature debris, increasing the risk of burns and cuts to operators and potentially igniting flammable materials, significantly reducing the safety factor in special operating scenarios. Furthermore, ambient temperature water inlet cannot effectively cool the high-pressure components of the cutting head. Long-term high-temperature operation will accelerate the aging of seals and nozzle wear, which not only increases the maintenance cost of the equipment, but may also lead to high-pressure water leakage due to component failure, further amplifying the safety risks of operation and bringing certain adverse effects to people's use. In order to overcome the shortcomings of the existing technology, we propose a fully intelligent water jet explosion-proof cutting water inlet low temperature treatment device and system. Summary of the Invention
[0004] The main objective of this invention is to provide a fully intelligent waterjet explosion-proof cutting water inlet cryogenic treatment device and system, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fully intelligent waterjet explosion-proof cutting cryogenic water inlet treatment device includes an outer frame. An anti-vibration base is installed inside one side of the outer frame. A compressor is fixedly installed on the upper part of one side of the anti-vibration base. An oil cooler is fixedly installed on the side of the anti-vibration base away from the compressor. A second pipe is connected to the upper part of the compressor, and a first pipe is connected to the side of the compressor near the second pipe. A fixing plate is fixedly installed in the middle of one side of the outer frame. An inlet filter is bolted to one side of the fixing plate. An outlet filter is bolted to the middle of the side of the fixing plate near the inlet filter. A heat exchanger is bolted to the side of the fixing plate away from the inlet filter. A controller is installed on the upper part of the outer frame near the compressor. Anti-slip suction cups are installed at the four lower corners of the outer frame.
[0006] Preferably, the end of the second pipe away from the compressor is connected to one end of the oil cooler, and the end of the first pipe away from the compressor is connected to the upper part of one side of the heat exchanger.
[0007] Preferably, a motor is fixedly installed on the side of the anti-vibration base near the compressor. The drive end of the motor is connected to a fourth pipe and a third pipe. The end of the fourth pipe away from the motor is connected to the middle of the first pipe. The end of the third pipe away from the motor is connected to the upper side of the water inlet filter.
[0008] Preferably, a seventh pipe is connected to the upper part of the side of the heat exchanger near the first pipe, the end of the seventh pipe away from the heat exchanger is connected to the side of the outlet water filter, a sixth pipe is connected to the end of the heat exchanger away from the seventh pipe, the end of the sixth pipe away from the heat exchanger is connected to the lower part of the side of the inlet water filter, and a second connecting pipe is connected to the side of the sixth pipe near the heat exchanger.
[0009] Preferably, a second nozzle is connected to the lower side of the water outlet filter, and a one-way valve is provided at the junction of the second nozzle and the water outlet filter.
[0010] Preferably, a check valve is provided on the lower side of the water inlet filter, a fifth pipe is connected to the middle of the check valve, a pressure gauge is provided at one end of the fifth pipe, and a first nozzle is connected to the end of the fifth pipe away from the pressure gauge.
[0011] Preferably, the side of the oil cooler closest to the second pipe is connected to a first connecting pipe, and the position of the first connecting pipe corresponds to the position of the second connecting pipe.
[0012] Preferably, a fully intelligent waterjet explosion-proof cutting cryogenic water inlet treatment system includes the following steps: S1: Device Start-up: Receives signals from various components of the equipment, such as temperature and pressure, controls the opening and closing of internal valve groups, and adjusts the flow and pressure of the cooling medium. By adjusting the medium parameters, it ensures the stable operation of each device. At the same time, it monitors the equipment status, realizes automated control, and starts the motor through the controller. After being powered on, it outputs power to drive the compressor to rotate. It is the power source of the entire equipment and drives the compressor to complete the compression operation. S2: Cooling Preparation: Driven by a motor, it compresses the medium; at the same time, it generates heat due to its operation, completing the core task of medium compression. It is the functional execution component of the equipment; the heat generated needs to be processed by the subsequent cooling device. The external cooling medium water first enters the inlet filter, filters out impurities and then outputs, purifying the cooling medium and preventing impurities from entering the subsequent device and causing blockage and wear, thus protecting the equipment components. S3: Circulation device: Receives heat from the compressor and exchanges heat with the filtered cooling medium, transferring heat to the cooling medium and quickly removing the heat generated by the compressor to prevent the compressor from being damaged by overheating. After the heat exchange is completed, the cooling medium flows through the outlet water filter, filters impurities again, and is discharged to further purify the cooling medium. At the same time, it ensures the cleanliness of the discharged or circulated medium and avoids contamination of the subsequent system.
[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a stable foundation for the cryogenic treatment system is laid through the coordinated design of inlet water pretreatment and power. The inlet water filter efficiently removes particulate impurities and suspended solids from the water, preventing blockages in subsequent pipelines and core components from the source and ensuring smooth medium flow. The controller precisely starts the motor, providing continuous and stable power output to the compressor, ensuring efficient operation of the cryogenic circulation system. The compressor uses dual pipelines to divert and transport the refrigerant. One portion is initially cooled by the oil cooler, effectively reducing the heat exchange load on the heat exchanger, while the other portion is directly delivered to the heat exchanger to store cold energy, improving the response speed of subsequent heat exchange. A third pipeline achieves precise connection between the pretreated inlet water and the heat exchanger, ensuring an orderly supply of inlet water to be cooled. The coordinated operation of all components ensures the cleanliness of the inlet water and provides sufficient power and cold energy reserves for subsequent efficient cooling, significantly improving the stability of system operation and the efficiency of initial preparation.
[0014] This invention utilizes a heat exchanger as the core to construct a cooling and stable output system, achieving both effective cooling and safety. The heat exchanger employs a dual-medium flow design to achieve rapid heat exchange between the incoming water and the cryogenic refrigerant. Combined with a fourth pipe for dynamic refrigerant flow regulation, this ensures the incoming water temperature rapidly drops to the target range and remains stable without fluctuations. The oil cooler and heat exchanger form an auxiliary circulation path through connecting pipes, effectively preventing water temperature rebound during continuous operation and enhancing cooling sustainability. The secondary filtration design of the outlet water filter further improves the cleanliness of the cryogenic water, preventing impurities from affecting cutting accuracy. The dual backflow prevention structure of the one-way valve and check valve, combined with real-time pressure monitoring by a pressure gauge, eliminates pipeline pressure disturbances and reduces safety risks in explosion-proof scenarios. The main and backup dual output paths ensure the continuity of cryogenic water supply, fully meeting the cooling requirements and safety standards of waterjet explosion-proof cutting.
[0015] This invention achieves a dual improvement in equipment maintenance convenience and operational adaptability through optimized structural design and intelligent control functions. The outer frame provides stable installation support for each component, and the anti-slip suction cups at the bottom effectively prevent equipment displacement during operation, enhancing the stability of explosion-proof operations. The vibration-damping base significantly reduces vibration generated by the motor and compressor, reducing component wear and noise pollution, and extending the equipment's service life. The fixing plate enables modular integrated installation of the filter and heat exchanger, allowing maintenance and repair to be completed without complex disassembly, significantly reducing maintenance costs and labor intensity. The controller integrates intelligent linkage functions, dynamically adjusting the operating parameters of each component according to the cutting load, achieving automated and precise control of low-temperature processing, flexibly adapting to different materials and cutting conditions of different durations, and realizing a synergy between structural stability, ease of operation and maintenance, and intelligent adaptability.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0019] Example 1, as Figures 1-7 As shown, in the water pretreatment stage, the external water first enters the water inlet filter 15 to filter out particulate impurities and suspended solids, completing the initial purification of the water. Simultaneously, the controller 3 starts the motor 5, which in turn starts and drives the compressor 2. Part of the high-temperature refrigerant produced by the compressor 2 is transported to the oil cooler 14 via the second pipe 10 for initial cooling, while the other part is directly transported to the heat exchanger 7 via the first pipe 9, reserving cooling capacity for subsequent heat exchange. Then, the pretreated water is transported to the water inlet channel inside the heat exchanger 7 via the third pipe 11 connected to the drive end of the motor 5, awaiting heat exchange cooling. The motor 5 provides the power source for the compressor 2, ensuring power output for low-temperature circulation; the compressor 2 is used to compress and circulate the refrigerant, providing the energy basis for subsequent cooling; the oil cooler 14 is used to initially cool the high-temperature refrigerant discharged from the compressor 2, reducing the load on the heat exchanger 7; the heat exchanger 7 is used to receive the high-temperature refrigerant transported by the compressor 2, preparing for subsequent heat exchange with the water. Example 2, as Figures 1-7As shown, heat exchanger 7 is then used as the core cooling component. Two media flow simultaneously within heat exchanger 7: one is low-temperature refrigerant from compressor 2, and the other is incoming water to be cooled from inlet filter 15. The two media exchange heat within heat exchanger 7, with the heat from the incoming water being rapidly absorbed by the refrigerant, causing the temperature to drop quickly to the target low-temperature range. During this process, the fourth pipe 12 connects motor 5 to the middle of the first pipe 9, assisting in regulating the refrigerant flow and ensuring a stable refrigerant supply within heat exchanger 7, preventing fluctuations in the cooling effect of the incoming water due to insufficient cooling capacity. The low-temperature water that has completed heat exchange is transported outwards via the sixth pipe 22; simultaneously, the first connecting pipe 21 on one side of oil cooler 14 can precisely connect to the second connecting pipe 23 on the sixth pipe 22, forming an auxiliary circulation path between oil cooler 14 and heat exchanger 7. The auxiliary circulation path between the oil cooler 14 and the heat exchanger 7 can re-transport the low-temperature refrigerant cooled by the oil cooler 14 to the heat exchanger 7, further enhancing heat exchange efficiency and ensuring that the inlet water temperature is maintained within a stable low-temperature range, avoiding water temperature rise due to continuous operation. After cooling, part of the low-temperature water is directly transported through the sixth pipe 22, and the other part is transported through the seventh pipe 24 to the outlet water filter 8 for secondary filtration to remove any minute impurities that may be generated in the pipeline. Finally, the pure low-temperature water is output to the water jet cutting system through the second nozzle 20 below the outlet water filter; the one-way valve 25 can strictly control the unidirectional flow of the low-temperature water, preventing pressure disturbances caused by media backflow. Meanwhile, the check valve 16 below the inlet filter, the fifth pipe 18, and the first nozzle 17 form a backup output path. The pressure gauge 19 monitors the pipeline pressure in real time to ensure the stability and safety of the low-temperature water output. The effect of the outlet filter is to ensure the cleanliness of the output low-temperature water and avoid impurities from affecting the cutting accuracy. At the same time, the one-way valve 25 connected to the lower side of 8 and the check valve 16 installed on the lower side of 15 are used to prevent the medium from flowing back, avoid pipeline pressure disturbance, and improve the operational safety in explosion-proof scenarios. Furthermore, the pressure status can be monitored in real time through the pressure gauges 19 installed on 18, and abnormalities can be warned in a timely manner to ensure the safety of operation in high-risk scenarios. Example 3, as Figures 1-7 As shown, the outer frame 1 of the device provides installation support for each component, ensuring the stability of the equipment structure; the anti-vibration base 4 can reduce the vibration of the compressor 2 and motor 5 during operation, reducing noise and component wear; the fixing plate 6 in the middle of one side of the outer frame 1 is used to realize the modular installation of the inlet filter 15, the outlet filter 8, and the heat exchanger 7, which facilitates maintenance and repair; the anti-slip suction cup 13 at the bottom of the outer frame 1 enhances the stability of the device on the work site, prevents equipment displacement, and improves the safety of explosion-proof operations; the controller 3 on the upper side of one side of the outer frame 1 is used to integrate intelligent control functions, link the operating parameters of each component, realize the automated and precise control of low-temperature processing, and adapt to the dynamic requirements of water jet explosion-proof cutting.
