DETAILED DESCRIPTION

[0020] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0021] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0022] Figure 1 This is a flow chart of a liquid supply control method provided in an embodiment of the present application. Figure 1 As shown, the liquid supply control method may include the following steps: S110, collecting the cutting mixed fluid generated during the operation of the machine tool equipment to a return fluid station, where the cutting mixed fluid includes used cutting fluid and aluminum chips.

[0023] Among them, cutting fluid is a functional liquid used by CNC machine tools and other metal processing equipment in cutting, grinding and other processes. It is mainly composed of water, mineral oil, surfactants, extreme pressure additives and other ingredients. It has the functions of cooling tools, lubricating cutting interfaces, cleaning chips, and rust-proofing workpieces and equipment. It can effectively ensure processing accuracy, extend tool life and improve production efficiency. After use, it is often mixed with metal debris (such as aluminum chips) to form waste liquid.

[0024] Cutting fluid mixture is the waste fluid obtained after machine tools use cutting fluid, which may include used cutting fluid and impurities such as aluminum chips.

[0025] The return liquid station is a device used to store cutting waste fluid after use of machine tool equipment, so that the cutting waste fluid stored in the return liquid station can be further processed later.

[0026] Based on this, machine tools need to use cutting fluid during operation, and after use, cutting waste fluid containing impurities will be generated. By collecting the cutting waste fluid into the return fluid station, the cutting mixture in the return fluid station can be further filtered and separated into the liquid and the target cutting fluid that can be put into use again after filtration and metal blocks formed by metal impurities, such as aluminum blocks formed by aluminum chips, can be obtained.

[0027] S120: Based on the liquid sensor, the liquid level of the cutting mixed liquid in the liquid return station is detected, and it is determined whether the liquid level is higher than a preset liquid level threshold.

[0028] Among them, a liquid sensor is a device used to detect the physical, chemical properties or state of a liquid and convert it into a measurable electrical signal or other form of signal. It can interact with the liquid through sensitive elements, sense the specific properties of the liquid (such as liquid level, flow, temperature, concentration, pH value, etc.), and convert these non-electrical signals into electrical signals (such as voltage, current, frequency, etc.) for display, processing or control.

[0029] The preset recovery threshold is a pre-set threshold used to determine the recovery time point of the cutting mixture. For example, by comparing the volume of the cutting mixture with the preset recovery threshold, the cutting mixture can be transported to the pretreatment equipment when the volume of the mixture is greater than the preset recovery threshold, that is, when the current accumulated mixture is large and subsequent processing operations can be carried out.

[0030] Based on this, according to the liquid sensor in the liquid return station, the liquid level of the cutting waste liquid stored in the liquid return station is detected in real time, so as to timely and accurately determine whether the liquid level in the liquid return station is higher than the preset liquid level threshold.

[0031] S130: If it is higher than , the cutting mixed fluid is transported to a pretreatment device for pretreatment, and after pretreatment, the aluminum chips deposited at the bottom of the pretreatment device are discharged to obtain the cutting fluid to be filtered.

[0032] Among them, the pretreatment equipment is a device used to perform preliminary treatment on the cutting mixture. For example, a coarse-pore filter or sedimentation method can be used to remove larger particle impurities (such as ≥50μm) in the waste liquid, thereby achieving preliminary filtration of the cutting mixture and obtaining metal impurities in the mixture.

[0033] Pretreatment can be understood as the preliminary filtration of cutting waste fluid by pretreatment equipment, so as to obtain aluminum chips in cutting waste fluid, that is, metal impurities in cutting waste fluid. Please refer to Figure 2 , Figure 2 A schematic diagram of a preprocessing method for controlling liquid supply provided in an embodiment of the present application; Figure 2 As shown, in actual application, the pretreatment system receives the cutting waste fluid after use of the machine tool equipment and is transported by the liquid supply pipeline, and pretreats the cutting waste fluid so that the obtained aluminum chips can be transported to the briquetting device, and the pretreated cutting fluid can be transported to the fine filtration system.

[0034] The cutting fluid to be filtered is the cutting fluid that has been pretreated by the pretreatment equipment, but may still contain impurities and needs further fine filtration.

[0035] Based on this, when it is determined that the liquid level in the current liquid return station is higher than the preset liquid level threshold, the cutting waste liquid in the liquid return station can be transported to the pretreatment equipment so that the pretreatment equipment can perform preliminary filtration on the cutting mixed liquid, thereby obtaining aluminum chips precipitated at the bottom of the pretreatment equipment, and obtaining the cutting fluid to be filtered after preliminary treatment.

[0036] S140, performing fine filtration on the cutting fluid to be filtered to obtain the target cutting fluid.

[0037] Fine filtration refers to the deep filtration of liquids through fine filtration devices and processes to remove finer impurities and particles, so that the liquid can reach higher purity and quality requirements; please refer to Figure 3 , Figure 3 A schematic diagram of fine filtration of a liquid supply control method provided in an embodiment of the present application; Figure 3 As shown, the filtering device receives the cutting fluid delivered by the liquid supply system and treated by the pretreatment system, and performs fine filtering on the cutting fluid according to the fine filtering system, thereby delivering the cutting fluid to the machine tool through the liquid supply system so that the machine tool can use the cutting fluid again, and the filtering device is flushed by the backwashing device, and the fine filtering system is deoiled by the oil removal device; when the machine tool is in non-working mode, the cutting fluid will circulate between the pretreatment system and the fine filtering system, thereby achieving repeated filtration.

[0038] The target cutting fluid is the cutting fluid that is obtained after fine filtration and can be reused in machine tools.

[0039] Based on this, the cutting fluid to be filtered is finely filtered to achieve a higher purity of the cutting fluid, and the target cutting fluid that can be recycled is obtained.

[0040] S150: Determine whether the current machine tool mode is the working mode. If so, deliver the target cutting fluid to each machine tool device for recycling.

[0041] The machine tool mode is the operation execution mode corresponding to the machine tool, which can include working mode and non-working mode. The working mode can be understood as the current machine tool needs to perform more tasks and needs to use more cutting fluid, and it is necessary to provide cutting fluid to the machine tool equipment at a high intensity; the non-working mode can be understood as the holiday mode, that is, the current machine tool equipment does not need to use much cutting fluid, and there is no need to provide cutting fluid to the machine tool equipment at a high intensity. In actual applications, the target cutting fluid after fine filtration can be repeatedly filtered at this time to further improve the purity of the cutting fluid.

[0042] Based on the feasible implementation of the above S110, the present application further provides a method for collecting the cutting mixed fluid generated during the operation of the machine tool equipment to a liquid return station, including the steps of: Based on the cutting fluid tank corresponding to each machine tool equipment, the cutting mixed fluid is collected and transported to the return fluid station through the conveying pipeline.

[0043] Among them, the cutting fluid tank is a device used by machine tools to temporarily store used cutting waste fluid; the delivery pipeline is a liquid delivery pipeline used to deliver the cutting mixed fluid to a designated location.

[0044] Based on this, the cutting waste fluid in the cutting fluid tank of the machine tool equipment is determined, thereby collecting the cutting waste fluid of all the machine tool equipment, and transporting the collected cutting waste fluid to the liquid return station through a conveying pipeline for conveying liquid.

[0045] Based on the feasible implementation of the above S120, the present application further provides the following steps after detecting the liquid level of the cutting mixed liquid in the liquid return station based on the liquid sensor and determining whether the liquid level is higher than a preset liquid level threshold: If the liquid level is higher than the preset liquid level threshold, a prompt message is generated and output according to the liquid level. The prompt information is information used to prompt the user of the current liquid level height in the liquid return station.

[0046] Based on this, if the liquid level of the cutting waste liquid stored in the current liquid return station is higher than the preset liquid level threshold, it means that there is too much liquid stored in the liquid return station and it needs to be transported to the pretreatment equipment for subsequent processing in time. Then, a prompt information containing the current liquid level height can be generated to prompt the user.

[0047] Based on the feasible implementation of the above S130, the present application further provides that if it is higher than, the cutting mixed fluid is transported to a pretreatment device for pretreatment, and after pretreatment, the aluminum chips deposited at the bottom of the pretreatment device are discharged to obtain the cutting fluid to be filtered, including the steps of: If the liquid level is higher than the preset liquid level threshold, the cutting mixture is transported to the pretreatment equipment for pretreatment, and after pretreatment, the aluminum chips deposited at the bottom of the pretreatment equipment are collected by the chip conveyor at the bottom of the pretreatment equipment and sent to the briquetting equipment to obtain aluminum blocks; Obtain cutting fluid to be filtered.

[0048] Among them, the chip conveyor is a device located at the bottom of the pretreatment equipment, which is used to separate metal debris (such as aluminum chips) in the cutting fluid. It can be a device that separates and discharges metal debris (such as aluminum chips, iron chips) in the cutting fluid from the liquid through mechanical transmission (such as chain plate, spiral, scraper type). It belongs to the bottom component of the pretreatment system.

[0049] The briquetting equipment is used to briquette metal impurities such as aluminum chips to obtain relatively complete metal blocks. According to the preset briquetting equipment, the collected aluminum chips are briquette-treated to obtain aluminum blocks, thereby improving the recovery rate and utilization rate of metal impurities in waste liquid.

[0050] Based on this, a chip conveyor is installed at the bottom of the pretreatment equipment to separate the aluminum chips in the cutting mixture from the liquid and output them to the briquetting equipment to obtain complete aluminum blocks.

[0051] Based on the feasible implementation of the above S140, the present application further provides a method of finely filtering the cutting fluid to be filtered to obtain the target cutting fluid, including the following steps: Based on the filtration equipment, the filtered cutting fluid is finely filtered to obtain the initial cutting fluid, and the target indicators of the initial cutting fluid are tested to obtain the corresponding index values ​​of each target indicator, including concentration, pH value, conductivity and temperature; Determine the preset indicator value corresponding to each target indicator, and compare each indicator value with the corresponding preset indicator value to obtain a comparison result; If the comparison result shows that all index values ​​are greater than the corresponding preset index values, the initial cutting fluid is determined to be the target cutting fluid; If the comparison result shows that there is at least one indicator that is not greater than the corresponding preset indicator value, it is determined that the initial cutting fluid is not the target cutting fluid.

[0052] Among them, the filtering equipment is a fine filtering equipment for fine filtering of the cutting fluid to be filtered. For example, the filtering equipment can remove fine particles (such as ≤5μm) and colloidal impurities through a high-precision filter element, membrane filtration or multi-stage filtration combination.

[0053] The initial cutting fluid is the cutting fluid that has been finely filtered, and the target indicators are the various liquid indicators corresponding to the initial cutting fluid, such as concentration, pH value, conductivity, temperature and other liquid indicators.

[0054] The preset index value is a preset value corresponding to each liquid index, such as a preset concentration index value corresponding to concentration, a preset pH index value corresponding to pH, a preset conductivity index value corresponding to conductivity, and the like.

[0055] Based on this, after the cutting fluid is finely filtered by the filtering equipment, it is necessary to further determine whether the various liquid indicators of the initial cutting fluid meet the requirements, so as to determine whether the initial cutting fluid can be used for the machine tool again, that is, whether the initial cutting fluid can be determined as the target cutting fluid. By determining the various liquid indicators and their corresponding preset indicator values, the various liquid indicators of the initial cutting fluid and the corresponding preset indicator values ​​are compared. If the comparison result is that all liquid indicators of the initial cutting fluid are greater than their respective corresponding preset indicator values, the initial cutting fluid can be determined as the target cutting fluid; if the comparison result is that there is at least one liquid indicator that is not greater than the corresponding preset indicator value, it indicates that the current initial cutting fluid does not meet the machine tool use requirements and the initial cutting fluid cannot be determined as the target cutting fluid.

[0056] Based on the feasible implementation of the above S150, the present application further provides a method for determining whether the current machine tool mode is the working mode, and if so, delivering the target cutting fluid to each machine tool equipment for recycling, including the steps of: If the machine tool mode is not the working mode, the filtering device is determined, and the target cutting fluid is circulated and filtered between the pretreatment device and the filtering device.

[0057] Among them, the circulation filtration is to repeatedly circulate and filter the target cutting fluid according to the pretreatment equipment and the filtering equipment, that is, the cutting fluid circulates in the pretreatment equipment and the filtering equipment, which ensures the fluidity of the cutting fluid and avoids the static precipitation of the cutting fluid. By repeatedly filtering the cutting fluid and filtering out fine impurities in the cutting fluid, the service life and use effect of the cutting fluid can be guaranteed.

[0058] Based on this, by determining that the current execution mode of the machine tool is not the working mode, that is, the working frequency of the machine tool is not high at this time, and there is no need to provide cutting fluid to the machine tool at high intensity, the target cutting fluid can be circulated and filtered through pretreatment equipment and filtration equipment at this time, thereby avoiding static sedimentation and repeatedly filtering impurities in the cutting fluid to further improve the purity of the cutting fluid.

[0059] Based on the feasible implementation of the above S150, the present application further provides the following steps: after determining whether the current machine tool mode is the working mode, and if so, delivering the target cutting fluid to each machine tool device for recycling: Determine flushing equipment and degreasing equipment; The filter equipment is flushed according to the flushing equipment, and the filter equipment is degreased according to the degreasing equipment.

[0060] Among them, the flushing equipment can flush the bottom of the liquid tank and the back of the filter in the filtering equipment, so that impurities will not accumulate at the bottom of the liquid tank and the filter will remain clean, thereby reducing the pollution of cutting fluid caused by impurity accumulation and filter clogging.

[0061] The oil removal equipment can extract the floating oil on the surface of the cutting fluid in the filtering equipment and separate and discharge it. It is mainly composed of an oil pump and a centrifuge.

[0062] Based on this, the filter equipment is cleaned by flushing equipment and degreasing equipment, avoiding contamination of the filter equipment by impurities and floating oil.

[0063] Please refer to Figure 4 , Figure 4 A method diagram of a liquid supply control method provided in an embodiment of the present application; Figure 4 As shown, step S1: when the system is used for the first time, the operator sets the corresponding parameters in the control system (1), including: the liquid level H1 of the pretreatment tank (2), the liquid level H2 of the fine filter tank (3), the cutting fluid concentration α in the tank, the starting working threshold β of the return system (5), the liquid level filling threshold γ of the production line machine tank, the working threshold q of the return system (5), and the working threshold p of the briquetting device. The control system (1) is started in automatic mode to start working.

[0064] Step S2: The liquid adding system (6) automatically adds liquid to the pretreatment system (2) and the fine filtration system (3) according to the cutting fluid concentration α set by the control system (1), and stops adding liquid when the liquid levels in the two liquid tanks reach the corresponding liquid level values ​​H1 and H2.

[0065] Step S3: The liquid supply system (4) starts working and delivers the cutting fluid in the fine filtration system (3) to the machine tool liquid tank and the pretreatment system (2) in two ways. When the liquid level in the production line machine tool liquid tank reaches the liquid addition threshold γ, the corresponding liquid addition solenoid valve opens and liquid is added to the production line machine tool liquid tank to ensure that the machine tool can use the cutting fluid normally. When the liquid level in the production line machine tool liquid tank does not reach the liquid addition threshold γ, the corresponding liquid addition solenoid valve closes and the liquid supply system (4) delivers all the cutting fluid to the pretreatment system (2).

[0066] Step S4: The cutting fluid and aluminum chips after use in the machine tool are mixed together and flow into the liquid return system (5). When the liquid return system (5) reaches the starting working threshold value q, the liquid return system starts to work and pumps the aluminum chips and cutting fluid mixture back to the pretreatment system (2). Step S5: The aluminum chips are separated in real time in the pre-treatment system (2) and sent to the briquetting device (9). When the briquetting device (9) reaches the working threshold value p, the briquetting device starts to work and compresses the aluminum chips into cakes for collection and discharge.

[0067] Step S6: The pretreatment system (2) receives the cutting fluid from the fine filtration system (3) and the liquid return system (5). When the liquid level in the pretreatment system reaches the set value H1, the liquid supply system (4) starts to work and transports the cutting fluid to the pretreatment system (3). Otherwise, it stops working.

[0068] Step S7: The fine filtration system (3) filters the cutting fluid from the pretreatment system (2) through a filtration device and returns it to the fine filtration box to ensure that there is no excess aluminum chips in the cutting fluid in the fine filtration system (3).

[0069] Step S8: The backwashing device (7) backwashes the filter device in the fine filtration system in real time under the control of the control system (1) to ensure the filtration effect of the filter device and prevent it from being blocked by impurities.

[0070] Step S9: Under the control of the control system (1), the oil removal device (8) extracts and removes the floating oil on the surface of the cutting fluid in the fine filtration system in real time to ensure that there is no excess oil on the surface of the cutting fluid to contaminate the cutting fluid.

[0071] Step S10: The liquid supply system (4) delivers the cutting fluid from the fine filtration system (3) to the machine tools of each production line for use, and the process returns to step S3, and the cycle continues indefinitely, thereby achieving the ability to centrally manage cutting fluid and centrally recover aluminum chips.

[0072] In some embodiments of the present application, a cutting mixture after use of a machine tool device is obtained, wherein the cutting mixture includes liquid and impurities such as aluminum chips. The cutting mixture is transported to a liquid return station for storage, and a preset liquid level threshold of the liquid return station is determined, so that the liquid level of the liquid return station is determined in real time according to a liquid sensor of the liquid return station, and the liquid level of the cutting mixture is compared with the preset liquid level threshold. When it is determined that the current liquid level of the mixture is greater than the preset liquid level threshold, that is, when a large amount of cutting mixture is stored in the current recycling device, the cutting mixture is transported to a pretreatment device, so that the cutting mixture is preliminarily filtered by the pretreatment device, and the deposited aluminum chips are collected by a chip conveyor at the bottom. Aluminum chips are collected and briquette is performed according to the briquetting equipment to obtain relatively complete aluminum blocks, so as to improve the recovery rate of metal impurities; the cutting fluid after preliminary filtration by the pretreatment equipment can be transported to the filtering equipment, and the cutting fluid is finely filtered according to the filtering equipment to obtain the initial cutting fluid, and further according to the various liquid indicators of the initial cutting fluid, the target cutting fluid that meets the indicator value requirements is determined, so that when the current machine tool mode is the working mode, the target cutting fluid is transported to the machine tool so that the machine tool can reuse the cutting fluid, and when the machine tool mode is not the working mode, the target cutting fluid is circulated and filtered between the pretreatment equipment and the filtering equipment, so as to improve the purity of the target cutting fluid.

[0073] In this way, cutting fluid can be supplied separately to different numbers of production line equipment, achieving the effect of centralized management and independent control, reducing management costs and improving management efficiency; effectively and accurately controlling the cutting fluid usage needs of the production line, realizing fully automated operation, and automatically separating the cutting fluid and aluminum chips to reduce human dependence; at the same time, the cutting fluid has a good transportation environment in the entire system, which can effectively control the use status of the cutting fluid and extend the service life of the cutting fluid; and improving the efficiency of providing cutting fluid to machine tools and the recovery rate of impurities.
