Description

Technical Field

[0001] This invention relates to the field of cutting fluid recycling technology, specifically to an intelligent cutting fluid purification and reuse device and an intelligent cutting fluid purification and reuse method. Background Technology

[0002] In the field of machining, cutting fluid is used extensively during the cutting, grinding, shearing, and drilling of blanks by cutting tools to achieve functions such as cooling, cleaning, rust prevention, and lubrication. Cutting fluid can not only reduce cutting temperature and extend tool life, but also reduce cutting force and improve the surface quality of the machined parts. However, during use, cutting fluid inevitably mixes with a large amount of solid particles such as metal chips and dust, as well as impurities such as machine tool lubricating oil. As the cycle time is extended, the accumulation of impurities in the cutting fluid will lead to a decline in the performance of the cutting fluid, deterioration and aging, making it difficult to continue to recycle or directly discharge.

[0003] Currently, various cutting fluid purification technologies have been proposed and applied. These include purification devices that use a mesh filter for coarse filtration, followed by secondary filtration and oil removal via gravity separation and a fine filter, and then a sedimentation device to adsorb minute impurities layer by layer; combined purification schemes using skimming and settling devices, magnetic filters, and hydrocyclones; and technologies that use hydraulic cavitation as the core technology, combined with multi-stage filtration, copolymer flotation, and fluid cutting to treat cutting fluid waste. In terms of circulating fluid supply, there are also technologies that treat cutting fluid return using multi-stage filtration and centrifugal separation devices, and employ sensors to monitor concentration and pressure. While centralized fluid supply control systems exist, these solutions still have several shortcomings in practical applications. Existing cutting fluid purification equipment often follows a fixed process flow with limited purification levels and routes. This makes it difficult to flexibly match appropriate purification strategies based on the actual contamination level of the cutting fluid. This can easily lead to over-purification of low-contamination cutting fluid, resulting in energy and material waste, or inadequate purification of high-contamination cutting fluid, affecting reuse quality. Furthermore, existing purification equipment often employs open-loop or simple feedback control, lacking intelligent decision-making capabilities based on real-time status data. Consequently, it cannot accurately output matching cutting fluid based on the specific cutting fluid requirements of downstream equipment. Summary of the Invention

[0004] The technical problem to be solved by this invention is that existing cutting fluid purification equipment has certain limitations. It cannot dynamically adjust the purification process according to actual working needs, which can easily lead to over-purification of low-contamination cutting fluid, resulting in waste of energy and materials. Alternatively, it may fail to fully purify high-contamination cutting fluid, affecting the quality of reuse. Furthermore, the control precision is low, and it is impossible to accurately output matching cutting fluid according to the specific cutting fluid requirements of downstream equipment.

[0005] To solve the above-mentioned technical problems, the first aspect of the present invention adopts the following technical solution: an intelligent cutting fluid purification and reuse device, comprising:

[0006] The intelligent main control system is used for data processing and overall control;

[0007] A cutting fluid delivery mechanism is used to collect and drive the flow of cutting fluid.

[0008] The cutting fluid purification mechanism is used to purify the cutting fluid according to preset multi-level purification standards.

[0009] The fluid storage management system is used to store cutting fluids of different purification levels and to dynamically adjust the cutting fluid according to the cutting fluid requirements;

[0010] The cutting fluid output mechanism is used to output the matching cutting fluid according to the corresponding cutting fluid requirements;

[0011] The cutting fluid delivery mechanism, cutting fluid purification mechanism, fluid storage management mechanism, and cutting fluid output mechanism are all connected to the intelligent main control system and operate under its control. The fluid storage management mechanism is equipped with a monitoring part for monitoring the status information of the stored cutting fluid and is connected to the intelligent main control system to transmit the status information of the stored cutting fluid in real time. After obtaining the corresponding cutting fluid demand, the intelligent main control system drives the cutting fluid output mechanism to output the matching cutting fluid, and drives the cutting fluid delivery mechanism and the cutting fluid purification mechanism to perform cutting fluid purification work to achieve cutting fluid purification and reuse cycle.

[0012] When this invention is in operation, it can realize a series of tasks such as automatic recovery and transportation of cutting fluid, multi-stage automatic purification of cutting fluid, and automatic conditioning of cutting fluid. It has a high degree of automation and intelligence. Through the unified scheduling of all actuators by the intelligent main control system, it can eliminate manual intervention and realize unmanned closed-loop management of cutting fluid from recovery, purification to supply. Through the liquid storage management mechanism, it can conveniently deliver cutting fluid that is highly matched to the cutting fluid demand, which can avoid the problems of over-purification or under-purification of cutting fluid. It can also make it easy for the intelligent main control system to adjust the purification strategy in real time according to the cutting fluid consumption rate and the contamination rate, effectively balancing the production rate and the consumption rate of liquid, and improving the continuous operation capability of intelligent cutting fluid purification and reuse equipment.

[0013] Preferably, the cutting fluid purification mechanism is provided with several purification devices, which include at least one of a coarse filter, a nano oil removal device, a cyclone separator, and a semiconductor ceramic filter. The outlet of the several purification devices is connected to several storage parts of the liquid storage management mechanism with different purification levels.

[0014] Preferably, several purification devices are arranged in series and / or in parallel along the purification route of the cutting fluid.

[0015] To solve the above-mentioned technical problems, the second aspect of the present invention adopts the following technical solution: a method for intelligent cutting fluid purification and reuse, using an intelligent cutting fluid purification and reuse device as described in any of the above aspects, comprising the following steps:

[0016] The intelligent main control system is initialized, and several purification routes are established according to different purification levels to obtain the purification execution matrix of the intelligent cutting fluid purification and reuse equipment.

[0017] The cutting fluid is recovered, and based on the real-time status information of the cutting fluid, it is introduced into a matching purification route. After completing the purification work of the current level, the cutting fluid is temporarily stored.

[0018] The system obtains the cutting fluid requirements, outputs matching cutting fluid based on these requirements, and performs secondary purification of the temporarily stored cutting fluid or dynamically adjusts the cutting fluid status parameters according to the requirements when the real-time status parameters of the cutting fluid do not match the cutting fluid requirements.

[0019] When in operation, this invention can realize a series of tasks such as automatic recovery of cutting fluid, multi-stage automatic purification of cutting fluid, and automatic conditioning of cutting fluid. It has a high degree of automation and intelligence. By establishing a purification execution matrix, it realizes the efficient association and combination of multiple purification nodes, which facilitates the rapid calling and scheduling of the intelligent main control system. It provides core logic support for intelligent operation, effectively improves the reproducibility and high fault tolerance of purification route planning, and can dynamically adjust the purification route according to the actual cutting fluid demand. It can output qualified cutting fluid while avoiding over-purification or under-purification of the recovered cutting fluid. It can output qualified cutting fluid and adjust subsequent purification work in a short time when the cutting fluid demand changes, without the need for a long adjustment process, and has a high response speed.

[0020] As a preferred option, when establishing several purification routes based on different purification levels to obtain the purification execution matrix of the intelligent cutting fluid purification and reuse equipment, the following steps are adopted:

[0021] A1: Obtain the operating information of the corresponding cutting fluid demand equipment, analyze it to obtain several contaminants of the cutting fluid, and set several different purification levels according to different contaminants;

[0022] A2: Based on the preset purification rules, establish several purification routes according to different purification levels, and determine the purification nodes in each purification route. By designing bypasses, associate the matching purification nodes to generate the purification execution matrix of the intelligent cutting fluid purification and reuse equipment.

[0023] When this invention is in operation, several contaminants are identified based on actual work needs, facilitating the rational planning of purification nodes. This ensures that the purification nodes closely match the actual production's contamination characteristics and liquid requirements, avoiding redundancy or insufficient purification capacity caused by unreasonable settings. It also reduces the design difficulty of purification route planning and improves purification targeting. Furthermore, by using bypass design to associate and match purification nodes, unnecessary purification nodes can be flexibly skipped or necessary purification nodes can be connected, thereby further reducing energy consumption and material waste caused by ineffective processes, avoiding insufficient purification, ensuring the efficiency of single-batch purification treatment, and facilitating rapid equipment adaptation and debugging for different production scenarios, shortening the project implementation and debugging cycle.

[0024] Preferably, when introducing the cutting fluid into a matching purification route based on the real-time status information of the cutting fluid, the following steps are adopted:

[0025] B1: Real-time status information of the recovered cutting fluid is collected, key indicators of the cutting fluid are extracted, and the purification task of the recovered cutting fluid is calculated according to the cutting fluid requirements. The purification task includes purification type and purification efficiency.

[0026] B2: By traversing the purification execution matrix through purification tasks, the matching degree between each purification route and the purification task is determined, and purification routes with a matching degree higher than the preset judgment threshold are output. The intelligent main control system then controls the cutting fluid to flow into the matching purification route.

[0027] When this invention is in operation, it quantifies the purification requirements of the recovered cutting fluid to obtain calculable and comparable indicators, which can provide accurate data for intelligent route matching, improve the accuracy of route selection, and automatically select suitable purification routes by traversing the purification execution matrix and judging the matching degree threshold. It can dynamically adjust in real time according to the state of cutting fluid contamination, ensuring that the purification process always runs on the optimal path.

[0028] Preferably, step B1 further includes the following steps: synchronously acquiring the measurement and status information of the cutting fluid in the intelligent cutting fluid purification and reuse equipment, calculating the total purification requirement of this part of the cutting fluid, calculating the purification task of this part of the cutting fluid according to the preset allowable processing cycle, and finally combining the purification task of the recycled cutting fluid to generate the final purification task.

[0029] When this invention is in operation, by synchronously incorporating the existing quantity and status information of cutting fluid in the equipment into the compensation calculation, it can achieve overall purification and coordination of the entire system's cutting fluid, making the purification scheduling more global, avoiding path conflicts and resource waste caused by decentralized scheduling, improving the overall operating efficiency of the equipment, avoiding local imbalance problems, ensuring the overall balance of the total quantity and status information of each level of fluid in the system, and rationally allocating the equipment processing load, avoiding equipment overload and excessively high energy consumption peaks caused by centralized processing, and also avoiding insufficient fluid storage caused by untimely processing, which affects production reuse, thus balancing the equipment operating load and the production fluid demand.

[0030] Preferably, step B1 further includes the following steps: establishing a cutting fluid state change trend model based on historical data of cutting fluid state information, predicting the cutting fluid state information after a unit time, and dynamically correcting the cutting fluid purification task based on the predicted state information through feedforward control.

[0031] When this invention is in operation, it establishes a state change trend model based on historical data, predicts the future state of the cutting fluid, and adjusts the purification task in advance. It can respond to scenarios where the pollution load increases in advance, so that the purification work can always match the changes in the pollution load ahead of time, avoiding the need to remedy the situation after the cutting fluid quality deteriorates. It ensures the continuous and stable quality of the recycled cutting fluid. By predicting and adjusting the purification strategy in advance, it can effectively reduce the fluctuation range of the cutting fluid performance indicators, improve the consistency of the output cutting fluid quality, and thus ensure the stability of the workpiece processing quality. It is particularly suitable for processing scenarios with long-term continuous production.

[0032] Preferably, in step B2, when traversing the purification execution matrix by the purification task, determining the matching degree between each purification route and the purification task, and outputting purification routes with a matching degree higher than a preset judgment threshold, the following steps are adopted: creating a task instruction vector according to the purification task based on a preset vector structure, and simultaneously establishing a purification performance vector for each purification route; calculating the matching degree between each purification route and the purification task through vector matching, and obtaining and outputting at least one purification route with a matching degree higher than the preset judgment threshold.

[0033] Preferably, step B2 further includes the following steps: monitoring the working status of each purification node in the current purification route, obtaining the status information of the cutting fluid at the inlet and outlet of the purification node, generating a purification efficiency attenuation coefficient, updating the purification efficiency of the purification route in real time according to the purification efficiency attenuation coefficient, and performing purification route replanning when the purification efficiency of the purification route is lower than the preset threshold of the purification efficiency required for the purification task.

[0034] During operation, this invention monitors the cutting fluid status at the inlet and outlet of each purification node to generate a purification efficiency attenuation coefficient. It can detect the performance degradation and blockage of filter elements and purification units in real time, enabling earlier and more accurate detection of purification node performance decline. This avoids substandard purification due to consumable failure. Based on the attenuation coefficient, it corrects the actual purification efficiency of the corresponding purification route in real time, ensuring that the performance parameters of the purification execution matrix always match the current actual operating state of the equipment. This avoids route matching distortion caused by purification node performance degradation, thus ensuring the continuous reliability of route matching results. It can also automatically trigger route replanning, switching to the appropriate route without manual intervention. This can significantly improve the autonomous operation and maintenance capabilities of the equipment and reduce quality accidents and downtime caused by purification node performance degradation.

[0035] The beneficial technical effects of this invention include:

This invention enables automatic recovery and delivery of cutting fluid, multi-stage automatic purification of cutting fluid, and automatic conditioning of cutting fluid, among other functions. It features a high degree of automation and intelligence.

The fluid storage management system facilitates the delivery of cutting fluid that is highly matched to the cutting fluid demand, avoiding the problems of over-purification or under-purification. Furthermore, the intelligent control system can easily adjust the purification strategy in real time based on the cutting fluid consumption rate and contamination rate, effectively balancing the fluid production rate and the fluid consumption rate, and improving the continuous operation capability of the intelligent cutting fluid purification and reuse equipment.

This provides core logical support for intelligent operation, effectively improving the reproducibility and fault tolerance of purification route planning. Furthermore, it can dynamically adjust the purification route according to actual cutting fluid requirements, avoiding over-purification or under-purification of the recovered cutting fluid while outputting qualified cutting fluid. It can also output qualified cutting fluid and adjust subsequent purification work within a short timeframe when cutting fluid requirements change, eliminating the need for lengthy adjustment processes and demonstrating high response speed.

[0038] 3. This invention identifies several contaminants based on actual work needs, facilitating the rational planning of purification nodes. This ensures that the purification nodes closely match the actual production's contamination characteristics and liquid requirements, avoiding redundancy or insufficient purification capacity due to unreasonable settings. It also reduces the design difficulty of purification route planning and improves purification targeting.

This makes the purification scheduling more comprehensive, avoids path conflicts and resource waste caused by decentralized scheduling, improves the overall operating efficiency of the equipment, and avoids local imbalances. It ensures the overall balance of the total quantity and status information of each level of fluid within the system, and can reasonably allocate the equipment's processing load. This avoids equipment overload and excessively high energy consumption peaks caused by centralized processing, as well as insufficient fluid storage due to untimely processing, which affects production reuse. It balances the equipment's operating load and the fluid demand for production.

[0041] 6. This invention establishes a state change trend model based on historical data, predicts the future state of the cutting fluid, and adjusts the purification task in advance. It can respond to scenarios with increased contamination load in advance, ensuring that the purification work always matches the changes in contamination load ahead of time. This avoids remedial measures after the cutting fluid quality deteriorates, ensuring the continuous and stable quality of the recycled cutting fluid. By predicting and adjusting the purification strategy in advance, the fluctuation range of the cutting fluid performance indicators can be effectively reduced, the consistency of the output cutting fluid quality can be improved, and the stability of the workpiece processing quality can be guaranteed.

[0048] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0049] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to indicate orientation or positional relationship for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0050] Example 1:

[0051] Please see Figure 1 and Figure 2 This embodiment discloses an intelligent cutting fluid purification and reuse device, comprising:

[0052] Intelligent main control system 1 is used for data processing and overall control;

[0053] The cutting fluid delivery mechanism 2 is used to recover and drive the flow of cutting fluid. During operation, any liquid delivery device such as a diaphragm pump or a centrifugal pump can be used.

[0054] The cutting fluid purification mechanism 3 is used to purify the cutting fluid according to a preset multi-level purification system.

[0055] The liquid storage management mechanism 4 is used to store cutting fluids of different purification levels and to dynamically adjust the cutting fluid according to the cutting fluid requirements;

[0056] The cutting fluid output mechanism 5 is used to output matching cutting fluid according to the corresponding cutting fluid requirements;

[0057] The cutting fluid delivery mechanism 2, cutting fluid purification mechanism 3, fluid storage management mechanism 4, and cutting fluid output mechanism 5 are all connected to the intelligent main control system 1 and operate under the control of the intelligent main control system 1. The fluid storage management mechanism 4 is equipped with a monitoring part for monitoring the status information of the stored cutting fluid and is connected to the intelligent main control system 1 to transmit the status information of the stored cutting fluid in real time. After obtaining the corresponding cutting fluid demand, the intelligent main control system 1 drives the cutting fluid output mechanism 5 to output the matching cutting fluid, and drives the cutting fluid delivery mechanism 2 and the cutting fluid purification mechanism 3 to perform cutting fluid purification work to realize the cutting fluid purification and reuse cycle. During operation, the various parts are connected through CNC valves. The intelligent main control system 1 can realize the dynamic adjustment of the purification fluid path by controlling several CNC valves, with a high degree of automation.

[0058] In operation, this embodiment can realize a series of tasks such as automatic recovery and transportation of cutting fluid, multi-stage automatic purification of cutting fluid, and automatic conditioning of cutting fluid. It has a high degree of automation and intelligence. Through the unified scheduling of all actuators by the intelligent main control system 1, it can eliminate manual intervention and realize unmanned closed-loop management of cutting fluid from recovery, purification to supply. Through the liquid storage management mechanism 4, it can conveniently deliver cutting fluid that is highly matched with the cutting fluid demand, which can avoid the problems of over-purification or under-purification of cutting fluid. It can also facilitate the intelligent main control system 1 to adjust the purification strategy in real time according to the cutting fluid consumption rate and contamination rate, effectively balancing the production rate and consumption rate of liquid, and improving the continuous operation capability of the intelligent cutting fluid purification and reuse equipment.

[0059] In this embodiment, the cutting fluid purification mechanism 3 is equipped with several purification devices, including at least one of a coarse filter, a nano-oil removal device, a cyclone separator, and a semiconductor ceramic filter. These devices can respectively achieve different purification mechanisms for solid particles, floating oil / emulsified oil, density difference impurities, and micron-level precision filtration. They can specifically remove various contaminants such as metal chips, miscellaneous oil, suspended solids, and fine particles from the cutting fluid. Of course, any other suitable purification device can also be used. The purification is comprehensive and adaptable to cutting fluid scenarios with different compositions and contamination types. The outlet ends of the several purification devices are respectively connected to several storage sections of the liquid storage management mechanism 4 with different purification levels. During operation, the several purification devices move along the clean surface of the cutting fluid... The purification routes can be arranged in series and / or parallel. The series-parallel design facilitates the matrix arrangement of purification devices, avoids the failure of pre-filters, and allows for flexible combination of various purification routes to meet the needs of different pollution levels and processing volumes. It also allows the intelligent main control system to select the shortest and most effective purification route based on the real-time pollution level of the cutting fluid. For example, lightly polluted cutting fluid can be treated by only a small number of purification devices, avoiding ineffective pressure drop, energy consumption, and consumable losses caused by flowing through all purification devices. This balances purification effect and operating economy, and also enables redundant design of purification work. When a single purification device fails, is maintained, or has consumables replaced, the remaining branches can continue to undertake the purification task without the need for a complete shutdown of the equipment. This can significantly reduce the impact on production continuity and improve overall operational reliability.

[0060] In practical implementation, to facilitate the movement of the intelligent cutting fluid purification and reuse equipment, a mounting cabinet 6 can be set up, and all mechanisms can be installed inside the mounting cabinet 6 to facilitate the transfer of the intelligent cutting fluid purification and reuse equipment to the corresponding cutting fluid demanding institution. Of course, rollers can also be set at the bottom of the mounting cabinet so that operators can push the intelligent cutting fluid purification and reuse equipment to the cutting fluid demanding institution.

[0061] Example 2:

[0062] Please see Figure 3 This embodiment provides an intelligent cutting fluid purification and reuse method, which uses an intelligent cutting fluid purification and reuse device as described in the above embodiment, and includes the following steps:

[0063] The intelligent main control system 1 is initialized, and several purification routes are established according to different purification levels to obtain the purification execution matrix of the intelligent cutting fluid purification and reuse equipment;

[0064] The cutting fluid is recovered, and based on the real-time status information of the cutting fluid, it is introduced into a matching purification route. After completing the purification work of the current level, the cutting fluid is temporarily stored.

[0065] The system obtains the cutting fluid requirements, outputs matching cutting fluid based on these requirements, and performs secondary purification of the temporarily stored cutting fluid or dynamically adjusts the cutting fluid status parameters according to the requirements when the real-time status parameters of the cutting fluid do not match the cutting fluid requirements.

[0066] In operation, this embodiment can realize a series of tasks such as automatic recovery of cutting fluid, multi-stage automatic purification of cutting fluid, and automatic conditioning of cutting fluid. It has a high degree of automation and intelligence. By establishing a purification execution matrix, it realizes the efficient association and combination of multiple purification nodes, which facilitates the rapid calling and scheduling of the intelligent main control system 1. It provides core logic support for intelligent operation, effectively improves the reproducibility and high fault tolerance of purification route planning, and can dynamically adjust the purification route according to the actual cutting fluid demand. It can output qualified cutting fluid while avoiding over-purification or under-purification of the recovered cutting fluid. It can output qualified cutting fluid and adjust subsequent purification work in a short time when the cutting fluid demand changes, without the need for a long adjustment process, and has a high response speed.

[0067] In this embodiment, when establishing several purification routes according to different purification levels to obtain the purification execution matrix of the intelligent cutting fluid purification and reuse equipment, the following steps are adopted:

[0068] A1: Obtain the operating information of the corresponding cutting fluid demand equipment, analyze it to obtain several contaminants of the cutting fluid, such as solid particles, floating oil / emulsified oil, pH changes, bacterial content, etc., and set several different purification levels according to different contaminants;

[0069] A2: Based on the preset purification rules, several purification routes are established according to different purification levels, and the purification nodes in each purification route are determined. By designing a bypass to associate the matching purification nodes, a purification execution matrix for the intelligent cutting fluid purification and reuse equipment is generated. During operation, each purification node is equipped with a corresponding purification device. Of course, composite purification devices can also be arranged as needed, which can further reduce the number of purification nodes, improve equipment integration, and reduce the occupied workspace.

[0070] In this embodiment, several contaminants are identified based on actual work needs, facilitating the rational planning of purification nodes. This ensures that the purification nodes closely match the actual production's contaminant characteristics and liquid requirements, avoiding redundancy or insufficient purification capacity due to unreasonable settings. It also reduces the design difficulty of purification route planning and improves purification targeting. Furthermore, by using bypass design to associate and match purification nodes, unnecessary purification nodes can be flexibly skipped or necessary purification nodes can be connected, thereby further reducing energy consumption and material waste caused by ineffective processes, avoiding insufficient purification, ensuring the efficiency of single-batch purification treatment, and facilitating rapid equipment adaptation and debugging for different production scenarios, shortening the project implementation and debugging cycle.

[0071] Example 3:

[0072] Please see Figure 3 This embodiment provides an intelligent cutting fluid purification and reuse method. The similarities with other embodiments will not be repeated here. The similarities will be described in detail below.

[0073] In this embodiment, when the cutting fluid is introduced into the matching purification route based on the real-time status information of the cutting fluid, the following steps are adopted:

[0074] B1: Real-time status information of the recovered cutting fluid is collected, key indicators of the cutting fluid are extracted, and the purification task of the recovered cutting fluid is calculated according to the cutting fluid requirements. The purification task includes purification type and purification efficiency.

[0075] B2: By traversing the purification execution matrix through the purification task, the matching degree between each purification route and the purification task is determined. Purification routes with a matching degree higher than the preset judgment threshold are output, and the intelligent main control system 1 controls the cutting fluid to flow into the matching purification route. In specific implementation, in step B2, when traversing the purification execution matrix through the purification task and determining the matching degree between each purification route and the purification task, and outputting purification routes with a matching degree higher than the preset judgment threshold, the following steps are adopted: a task instruction vector is created according to the purification task based on the preset vector structure, and a purification performance vector for each purification route is established simultaneously. The matching degree between each purification route and the purification task is calculated through vector matching, and at least one purification route with a matching degree higher than the preset judgment threshold is obtained and output.

[0076] In this embodiment, by quantifying the purification requirements of the recovered cutting fluid, a calculable and comparable clear indicator is obtained, which can provide accurate data basis for intelligent route matching, improve the accuracy of route selection, and automatically select suitable purification routes by traversing the purification execution matrix and judging the matching degree threshold. It can make dynamic adjustments in real time according to the state of cutting fluid contamination, ensuring that the purification process always runs on the optimal path.

[0077] As a further improvement to this embodiment, it is also necessary to monitor the working status of each purification node in the current purification route, obtain the status information of the cutting fluid at the inlet and outlet of the purification node, generate a purification efficiency attenuation coefficient, and update the purification efficiency of the purification route in real time according to the purification efficiency attenuation coefficient. When the purification efficiency of the purification route is lower than the preset threshold of the purification efficiency required by the purification task, the purification route replanning is performed. During the operation, the task instruction vector is constructed by the following calculation formula:

[0078] ;

[0079] Where: T is the task instruction vector. Let i be the target requirement value of the i-th item in the task instruction vector;

[0080] The purification efficiency attenuation coefficient of the purification node is calculated using the following formula:

[0081] ;

[0082] in: Let i be the current purification efficiency of the i-th purification index at purification node k. To determine the i-th contamination concentration of the cutting fluid at the purification node k inlet, The concentration of the i-th contaminant at the outlet of the cutting fluid at purification node k. Let be the current purification efficiency attenuation coefficient of the i-th purification index at purification node k.

[0083] The overall purification efficiency of the purification route is calculated using the following formula:

[0084] ;

[0085] in: Let be the total purification efficiency of the i-th purification index for the j-th purification route;

[0086] The purification performance vector for each purification route is calculated using the following formula:

[0087] ;

[0088] in: Let j be the purification performance vector of the j-th purification route. Let i be the purification performance vector of the i-th purification index for the j-th purification route;

[0089] During operation, the overall matching degree between each purification route and the purification task is calculated using the following formula:

[0090] ;

[0091] in: Let be the overall matching degree between the j-th purification route and the purification task. Of course, in actual work, any other suitable vector matching algorithm can also be used.

[0092] In this embodiment, by monitoring the cutting fluid status at the inlet and outlet of each purification node, a purification efficiency attenuation coefficient is generated. This allows for real-time sensing of performance degradation and blockage in filter elements and purification units, enabling earlier and more accurate detection of purification node performance decline. This avoids substandard purification due to consumable failure and, based on the attenuation coefficient, real-time correction of the actual purification efficiency of the corresponding purification route. This ensures that the performance parameters of the purification execution matrix always match the current actual operating state of the equipment, avoiding route matching distortion caused by purification node performance degradation. This guarantees the continuous reliability of route matching results and can automatically trigger route replanning, switching to the appropriate route without manual intervention. This significantly improves the equipment's autonomous operation and maintenance capabilities and reduces quality incidents and downtime caused by purification node performance degradation.

[0095] In this embodiment, step B1 further includes the following steps: synchronously acquiring the measurement and status information of the cutting fluid in the intelligent cutting fluid purification and reuse equipment, calculating the total purification requirement of this portion of the cutting fluid, and calculating the purification task of this portion of the cutting fluid according to the preset allowable processing cycle. Finally, the purification task is generated by combining the purification task of the recycled cutting fluid. During operation, the total amount of mixed cutting fluid and the initial concentration are calculated using the following formula:

[0096] ;

[0097] in: This represents the total amount of cutting fluid after mixing. Based on the current cutting fluid inventory, To recover the remaining cutting fluid during the treatment cycle. For the i-th contamination concentration vector of the recovered cutting fluid, Let i be the concentration of the i-th pollution item. Let i be the contamination concentration vector of the i-th element of the existing cutting fluid;

[0098] The single-pass purification efficiency of the purification route for the cutting fluid within the allowable treatment cycle is calculated using the following formula:

[0099] ;

[0100] in: Let be the single-cycle purification efficiency of the i-th purification index. Let i be the target requirement value for the i-th item. To allow the total number of loops within the processing cycle, Design the circulation flow rate for the cutting fluid. This is the preset allowed processing cycle;

[0101] The final task instruction vector for the purification task is calculated using the following formula:

[0102] ;

[0103] During operation, the purification execution matrix can be traversed through the final task instruction vector to calculate the matching degree of each purification route, thereby selecting highly matching purification routes.

[0104] In this embodiment, by synchronously incorporating the existing cutting fluid quantity and status information within the equipment into the compensation calculation, the overall purification and coordination of the entire system's cutting fluid can be achieved. This makes the purification scheduling more global, avoids path conflicts and resource waste caused by decentralized scheduling, improves the overall operating efficiency of the equipment, and avoids local imbalance problems. It ensures the overall balance of the total amount and status information of each level of fluid within the system, and can reasonably allocate the equipment processing load. This avoids equipment overload and excessively high energy consumption peaks caused by centralized processing, and also avoids insufficient fluid storage due to untimely processing, which affects production reuse. It balances the equipment operating load and the fluid demand for production.

[0105] In specific implementation, in order to further improve the response speed, step B1 also includes the following steps: establishing a cutting fluid state change trend model based on historical data of cutting fluid state information, predicting the cutting fluid state information after a unit time, and dynamically correcting the cutting fluid purification task based on the predicted state information through feedforward control.

[0106] In this embodiment, a state change trend model is established based on historical data to predict the future state of the cutting fluid and adjust the purification task in advance. This allows for proactive responses to scenarios with increased contamination load, ensuring that the purification work always anticipates changes in contamination load and avoids remedial measures after the cutting fluid quality deteriorates. This guarantees the continuous and stable quality of the recycled cutting fluid. By predicting and adjusting the purification strategy in advance, the fluctuation range of the cutting fluid performance indicators can be effectively reduced, improving the consistency of the output cutting fluid quality and thus ensuring the stability of the workpiece machining quality. This is particularly suitable for machining scenarios with long-term continuous production.

[0107] The beneficial technical effects of this embodiment include: the present invention can realize a series of tasks such as automatic recovery and transportation of cutting fluid, multi-stage automatic purification of cutting fluid, and automatic conditioning of cutting fluid. It has a high degree of automation and intelligence. Through the unified scheduling of all actuators by the intelligent main control system, it can eliminate manual intervention and realize unmanned closed-loop management of cutting fluid from recovery, purification to supply. Through the liquid storage management mechanism, it can conveniently transport cutting fluid that is highly matched with the cutting fluid demand, which can avoid the problems of over-purification or under-purification of cutting fluid. It can also facilitate the intelligent main control system to adjust the purification strategy in real time according to the cutting fluid consumption rate and contamination rate, effectively balance the production rate and consumption rate of liquid, and improve the continuous operation capability of intelligent cutting fluid purification and reuse equipment.
