[0005] To this end, the present invention provides an automatically controlled energy-saving fine mixing acid unit to overcome the problem in the prior art that the ion exchange resin cannot be fully utilized due to unreasonable adjustment of the acid wastewater flow rate and stirring method.

[0006] To achieve the above object, the present invention provides an energy-saving acid mixing unit with automatic control, comprising:

[0007] The filter chamber is arranged at the first section of the fine mixing acid unit and is used to filter the acid wastewater to obtain the initial acid wastewater, and has multiple layers of filter screens built in it;

[0008] A grabbing device, which is arranged in the filtering bin and is used to remove agglomerated blockages;

[0009] An imaging device, which is arranged on the upper part of the filter chamber and is used to photograph the agglomerated blockages;

[0010] A mixed bed connected to the filter tank via a first pipeline and used for purifying the initial acidic wastewater;

[0011] A saturated resin recovery bin connected to the upper portion of the mixed bed for recovering saturated resin, wherein the saturated resin is an ion exchange resin that absorbs pollutants to a saturated state during the filtration of acidic wastewater;

[0012] A lifting device, which is arranged at the bottom of the mixed bed and can move up and down in the mixed bed, comprises a lifting support rod, a filter screen, a sliding sleeve and a plurality of brackets connected to the sliding sleeve, wherein the filter screen is connected to the sliding sleeve through the bracket, and the lifting support rod is slidably connected to the sliding sleeve;

[0013] A pure water detection device, which is arranged at the mixed bed drain outlet and is used to detect the heavy metal content of pure water;

[0014] A flow meter, which is arranged at the mixed bed drain port and is used to detect the pure water flow rate;

[0015] A flow rate control valve, which is arranged at the drainage port of the filter chamber and is used to control the flow rate of the acidic wastewater entering the mixed bed;

[0016] A data analysis module, which is connected to the pure water detection device, the imaging device and the flow meter, and determines whether to replace the filter screen according to the area of ​​the agglomerated blockage; determines whether to replace the ion exchange resin in the mixed bed according to the initial heavy metal content comparison result; adjusts the opening angle or lifting height of the lifting device according to the first pure water flow comparison result; and determines whether to adjust the initial stirring period according to the second pure water flow comparison result to obtain the target stirring period;

[0017] The central control module is connected to the lifting device and the flow control valve, and is used to control the lifting device to adjust the opening area, lifting height and rotation speed, or adjust the opening of the flow control valve according to the output instructions of the data analysis module.

[0018] Furthermore, the pure water detection device detects the heavy metal content in the pure water in an initial detection cycle to obtain the initial pure water heavy metal content, and the data analysis module compares the initial pure water heavy metal content with the target pure water heavy metal content range to obtain an initial heavy metal content comparison result, and determines whether to replace the ion exchange resin in the mixed bed according to the initial heavy metal content comparison result.

[0019] Further, in the case of replacing the ion exchange resin, the central control module adjusts the initial detection cycle according to the purification time to obtain a first detection cycle;

[0020] The purification time is the time from the initial purification of the mixed bed to the replacement of the ion exchange resin.

[0021] Furthermore, based on the first detection cycle, the flow meter detects the pure water flow to obtain the actual pure water flow, the data analysis module compares the actual pure water flow with the preset pure water standard flow range to obtain a first pure water flow comparison result, and the data analysis module adjusts the opening angle or lifting height of the lifting device according to the first pure water flow comparison result.

[0022] Furthermore, in the case where adjusting the opening angle and the lifting height of the lifting device cannot satisfy the actual pure water flow rate within the pure water standard flow rate range, the control module controls the lifting device to rotate at the initial rotation speed or replace the ion exchange resin.

[0023] Furthermore, in the case where the ion exchange resin is not replaced, the data analysis module adjusts the initial opening of the flow rate control valve according to the absolute value of the difference between the initial pure water heavy metal content detected by the pure water detection device and the target pure water heavy metal content to obtain the target opening of the flow rate control valve.

[0024] Furthermore, in the case of increasing the flow rate of acidic wastewater, the central control module controls the flowmeter to detect the pure water flow at the mixed bed outlet to obtain a first actual pure water flow, and the data analysis unit compares the first actual pure water flow with a preset pure water standard flow range to obtain a second pure water flow comparison result.

[0025] Furthermore, the data analysis module determines whether to adjust the initial stirring period according to the comparison result of the second pure water flow rate to obtain a target stirring period;

[0026] The initial stirring period is determined according to the duration from the initial moment of the mixed bed purification of acidic wastewater to the moment when the heavy metal content of pure water is greater than the target heavy metal content of pure water.

[0027] Furthermore, multiple layers of filter screens are arranged in the filter bin, and the data processing module determines whether to replace the filter screen according to the area of ​​the filter screen covered by the blockage.

[0028] Furthermore, in the case of blockage accumulation, the central control module controls the grabbing device to remove the aggregated blockage accumulated in the filter screen.

[0029] Compared with the prior art, the beneficial effect of the present invention is that by setting a filter bin and a multi-layer filter screen, solid particles in acidic wastewater can be effectively filtered, the burden of subsequent treatment devices can be reduced, and the overall wastewater treatment efficiency can be improved. The setting of the grabbing device enables the agglomerated blockage in the filter bin to be automatically removed, reducing the workload of manual cleaning and improving the automation of the equipment. The use of the imaging device enables the operator to observe the situation of the agglomerated blockage in real time, which helps to find problems and deal with them in time. The use of the mixed bed can effectively purify the initial acidic wastewater, remove pollutants such as heavy metals, and improve the water quality of the effluent. The design of the saturated resin recovery bin enables the saturated resin to be recovered and recycled, reducing the operating cost. The setting of the lifting device enables the purification effect in the mixed bed to be adjusted as needed, and the coordinated use of the pure water detection device and the flow meter can accurately control the water quality and flow. The combination of the data analysis module and the central control module realizes the automatic adjustment of the equipment operation parameters according to the real-time data, and improves the intelligent management level of the system. Through the monitoring and analysis of various parameters by the data analysis module, the replacement cycle of the filter screen, the replacement time of the ion exchange resin and the stirring cycle can be optimized, thereby reducing the operating cost. The setting of the flow rate control valve ensures the stability of the flow rate of the acidic wastewater entering the mixed bed, thereby improving the stability and reliability of the entire system.

[0030] Furthermore, the central control module can automatically execute corresponding control instructions according to the test results, reducing manual intervention and improving the automation of the system. By regularly testing the heavy metal concentration of pure water and replacing the ion exchange resin in time, it is ensured that the water quality output by the fine mixing acid unit meets the target pure water heavy metal content range, ensuring the final water safety. The resin is only replaced when the initial pure water heavy metal content exceeds the target range, avoiding unnecessary resin replacement, extending the service life of the resin, and reducing operating costs. By precisely controlling the resin replacement process, the system downtime is reduced and production efficiency is improved. By recycling and regenerating saturated resin, the generation of waste is reduced, the recycling of resources is achieved, and environmental protection requirements are met.

[0031] Furthermore, by recording the purification time and adjusting the first detection cycle accordingly, it can be ensured that the resin is tested in time when it is close to saturation, thereby avoiding the risk of excessive heavy metal content. By determining the detection cycle according to the actual purification time, the saturation time of the resin can be predicted more accurately, unnecessary resin replacement can be reduced, and the service life of the resin can be extended. By optimizing the detection cycle, unnecessary detection and resin replacement are reduced, and operating costs are reduced. Automated detection cycle adjustment improves the adaptive ability of the fine mixing acid unit, ensuring the stable operation and water quality safety of the fine mixing acid unit. Reducing the frequency of resin replacement means reducing the amount of waste resin processed, which has a positive impact on the environment. Since the first detection cycle is positively correlated with the purification time, the pure water detection device can perform timely detection when the resin saturation reaches a certain level to ensure water quality. Reasonable detection cycles reduce resource waste and improve economic benefits. The adaptive adjustment of the fine mixing acid unit improves the reliability of the overall operation and reduces the possibility of human error.

[0032] Further, for the case where the first pure water flow rate comparison result is that the first pure water flow rate is greater than the maximum value of the standard flow rate interval, the central control module controls the lifting device to open the filter screen to slow down the purification and thus slow down the clean water flow to protect the mixed bed equipment. For the case where the first pure water flow rate comparison result is that the first pure water flow rate is less than the minimum value of the standard flow rate interval, the central control module controls the lifting device to raise the lifting support rod to obtain the lifting height of the first lifting support rod, and controls the lifting device to open the filter screen to obtain the opening area of ​​the second filter screen, which can change the original precipitation state of the ion exchange resin by lifting the lifting device, so that the gap between the ion exchange resins is increased and the purification capacity is increased. By adjusting the lifting device, the actual flow of pure water is ensured to remain in the preset pure water standard flow range, thereby ensuring the stability of the process and product quality. Through automated control, manual intervention is reduced, production efficiency is improved, and operating costs are reduced. Accurate adjustment is performed according to the actual reading of the flow meter to ensure that the flow rate is within the allowable error range. Real-time monitoring and rapid response can adjust the flow rate in time to avoid production interruptions caused by flow fluctuations. By avoiding damage to the equipment caused by excessive or too small flow, the service life of the mixed bed and other related equipment can be extended. Avoids decreased production efficiency or water quality problems due to flow fluctuations.

[0033] Furthermore, by adjusting the opening angle and lifting height of the lifting device, it is possible to automatically try to increase the flow rate, reduce manual intervention, and improve operational efficiency. When adjusting the opening angle and lifting height is ineffective, the control module changes the distribution state of the ion exchange resin by rotating the lifting device, which helps to improve the distribution of the ion exchange resin and thus increase the flow rate. The data analysis module continuously monitors the actual pure water flow rate through the flow meter and compares it with the standard flow rate range, ensuring the real-time feedback and self-adjustment ability of the fine mixing acid unit. If the second pure water flow comparison result shows that the flow rate has returned to the standard flow rate range after rotating the lifting device, the central control module will not replace the resin, thereby avoiding unnecessary costs and downtime. If the rotation adjustment still fails to make the flow rate reach the standard, the central control module will trigger the resin replacement program to ensure that the fine mixing acid unit can continue to provide pure water flow that meets the standard. Avoiding unnecessary replacement of ion exchange resins can extend the service life of the resin. The fine mixing acid unit can automatically select the most appropriate adjustment measures according to actual conditions, thereby improving the flexibility of operation.

[0034] Furthermore, by real-time monitoring and dynamic adjustment of the flow rate of acidic wastewater, ion exchange resins can be used more effectively, the efficiency of heavy metal removal can be improved, and the heavy metal content of the output pure water can be ensured to be stable within the safety standard range, thereby protecting the health of end users. By accurately controlling the flow rate of acidic wastewater, unnecessary over-treatment can be avoided, and the use of ion exchange resins and the consumption of chemical reagents can be saved. Reasonable control of the flow rate helps to reduce the wear of the resin and extend its service life. The automation system reduces the need for manual intervention and reduces the risk of operating errors. The real-time monitoring of the pure water detection device and the rapid feedback mechanism of the data analysis module enable the fine mixing acid unit to respond to water quality changes in real time and maintain the stability of the treatment effect. The automatic adjustment process reduces the manual intervention of operators and improves the level of automation. By reasonably adjusting the flow rate, the use of acidic wastewater is optimized and unnecessary consumption is reduced. It is ensured that the heavy metal content of pure water meets the target standard and the quality of the final product is improved. By making the absolute value of the difference between the initial heavy metal content and the minimum value of the target pure water heavy metal content positively correlated with the target opening of the flow rate control valve, it is ensured that the heavy metal content of pure water meets the standard while ensuring the purification efficiency.

[0035] Furthermore, by real-time monitoring of the actual pure water flow rate and comparing it with the standard flow rate range, the fine mixing acid unit can adjust the stirring cycle according to the comparison results of the second pure water flow rate, thereby optimizing the purification efficiency of the mixed bed and ensuring that the heavy metal content meets the standard. The data analysis module accurately adjusts the stirring cycle according to the flow rate difference, which helps to achieve more refined operation control and improve the automation level of the system. By shortening the stirring cycle, energy consumption and equipment wear can be reduced while ensuring the treatment effect, and the operating cost can be reduced. Keeping the stirring cycle matching the flow rate helps to maintain the stable operation of the mixed bed and reduce the problem of unstable water quality caused by flow fluctuations. The fine mixing acid unit can automatically adjust the stirring cycle according to different flow conditions to adapt to different treatment requirements and operating conditions. By shortening the stirring cycle, the fine mixing acid unit can respond more quickly to the situation of insufficient actual flow of the first pure water, increase the processing speed, and ensure the heavy metal removal effect. Fine-tuning the stirring cycle helps to maintain the optimal operating state of the system, ensuring water quality while avoiding over-treatment. When the actual flow rate of the first pure water exceeds expectations, keeping the stirring cycle unchanged can ensure that the system will not reduce the treatment effect due to excessive flow.

[0036] Furthermore, by setting up multiple layers of filters with different apertures, solid particles of different sizes can be effectively intercepted, the overall filtration efficiency can be improved, and the outflow water quality can be ensured to meet the standards. By periodically monitoring the coverage area of ​​the blockage and removing it in time, the filter can be prevented from being over-blocked and its service life can be extended. The coordinated use of the imaging device and the data processing module realizes the automatic monitoring and evaluation of the blockage of the filter, reduces manual intervention, and improves the level of automation. The central control module controls the grabbing device to automatically remove the blockage, which can maintain the normal operation of the filter chamber without stopping the machine, reducing the downtime caused by replacing the filter. By comparing the preset threshold and the actual flow rate, it is possible to accurately determine when the filter needs to be replaced, making the maintenance operation more accurate and efficient. Timely removal of blockages and replacement of filters can effectively prevent the decline of filtration effect and ensure the safety of the final water quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] This embodiment provides an energy-saving acid mixing unit with automatic control, comprising:

[0048] The filter chamber 1 is arranged at the first section of the fine mixing acid unit and is used to filter the acid wastewater to obtain the initial acid wastewater. The filter chamber 1 is equipped with a multi-layer filter screen 2 and a flow meter 3.

[0056] A pure water detection device 13, which is arranged at the mixed bed drain outlet and is used to detect the heavy metal content of pure water;

[0057] A flow meter 11, which is arranged at the mixed bed drain port and is used to detect the pure water flow rate;

[0058] A flow rate control valve 12, which is arranged at the drainage port of the filter chamber and is used to control the flow rate of the acid wastewater entering the mixed bed;

[0059] A data analysis module, which is connected to the pure water detection device, the imaging device and the flow meter, and determines whether to replace the filter screen according to the area of ​​the agglomerated blockage; determines whether to replace the ion exchange resin in the mixed bed according to the initial heavy metal content comparison result; adjusts the opening angle or lifting height of the lifting device according to the first pure water flow comparison result; and determines whether to adjust the initial stirring period according to the second pure water flow comparison result to obtain the target stirring period;

[0060] The central control module is connected to the lifting device and the flow control valve, and is used to control the lifting device to adjust the opening area, lifting height and rotation speed, or adjust the opening of the flow control valve according to the output instructions of the data analysis module.

[0061] By setting up a filter bin and a multi-layer filter, solid particles in acidic wastewater can be effectively filtered, reducing the burden of subsequent treatment devices and improving the overall wastewater treatment efficiency. The setting of the grabbing device enables the agglomeration blockage in the filter bin to be automatically removed, reducing the workload of manual cleaning and improving the automation of the equipment. The use of the imaging device enables the operator to observe the situation of the agglomeration blockage in real time, which helps to find problems and deal with them in time. The use of the mixed bed can effectively purify the initial acidic wastewater, remove pollutants such as heavy metals, and improve the water quality of the effluent. The design of the saturated resin recovery bin allows the saturated resin to be recovered and reused, reducing operating costs. The setting of the lifting device allows the purification effect in the mixed bed to be adjusted as needed, and the use of the pure water detection device and the flow meter can accurately control the water quality and flow. The combination of the data analysis module and the central control module realizes the automatic adjustment of the equipment operation parameters according to the real-time data, and improves the intelligent management level of the system. Through the monitoring and analysis of various parameters by the data analysis module, the replacement cycle of the filter, the replacement time of the ion exchange resin and the stirring cycle can be optimized, thereby reducing the operating cost. The setting of the flow rate control valve ensures the stability of the flow rate of the acidic wastewater entering the mixed bed, thereby improving the stability and reliability of the entire system.

[0062] Specifically, the pure water detection device detects the heavy metal content in the pure water in an initial detection cycle to obtain the initial pure water heavy metal content. The data analysis module compares the initial pure water heavy metal content with the target pure water heavy metal content range to obtain an initial heavy metal content comparison result, and determines whether to replace the ion exchange resin in the mixed bed based on the initial heavy metal content comparison result.

[0063] At the beginning of each test cycle, the pure water testing device analyzes the heavy metal content of the pure water.

[0064] The data analysis module receives the initial pure water heavy metal content data and compares the initial pure water heavy metal content with the target pure water heavy metal content range.

[0065] If the initial heavy metal content comparison result shows that the initial pure water heavy metal content is greater than the maximum value of the target pure water heavy metal content range, the central control module controls the fine mixing acid unit to shut down, and controls the sliding sleeve to rise and fix along the lifting support rod to open the filter screen, the lifting support rod moves upward to push the saturated resin into the saturated resin recovery bin to clean the mixed bed, and the resin regeneration bin introduces the regenerated ion exchange resin into the mixed bed, wherein the area of ​​the filter screen after opening is smaller than the bottom area of ​​the mixed bed;

[0066] If the initial heavy metal content comparison result shows that the initial pure water heavy metal content is within the target pure water heavy metal content range, the control module does not issue a control instruction;

[0067] If the initial heavy metal content comparison result shows that the initial pure water heavy metal content is less than the minimum value of the target pure water heavy metal content range, the control module controls the flow rate control valve to increase the opening degree;

[0068] Restart the fine mixing acid unit and conduct tests to ensure that the water quality meets the standards.

[0069] Preferably, the target pure water heavy metal content range is 0.01-0.05 mg / L, and the heavy metals include but are not limited to cadmium, chromium, copper, lead, mercury, nickel, silver, gold and zinc, etc., which are not specifically limited in this embodiment.

[0070] The central control module can automatically execute the corresponding control instructions according to the test results, reducing manual intervention and improving the automation of the system. By regularly testing the heavy metal concentration of pure water and replacing the ion exchange resin in time, it is ensured that the water quality output by the fine mixing acid unit meets the target pure water heavy metal content range, ensuring the final water safety. The resin is replaced only when the initial pure water heavy metal content exceeds the target range, avoiding unnecessary resin replacement, extending the service life of the resin, and reducing operating costs. By precisely controlling the resin replacement process, the system downtime is reduced and production efficiency is improved. By recycling and regenerating saturated resin, the generation of waste is reduced, the recycling of resources is achieved, and environmental protection requirements are met.

[0071] Specifically, in the case of replacing the ion exchange resin, the central control module adjusts the initial detection cycle according to the purification time to obtain a first detection cycle;

[0072] The purification time is the time from the initial purification of the mixed bed to the replacement of the ion exchange resin.

[0073] The pure water detection device records the time when the pure water is purified to the time when the heavy metal content of the pure water is greater than the maximum value of the target pure water heavy metal content range, that is, the purification time.

[0074] The first detection cycle is determined by the purification time. During the detection process, the detection cycle is adjusted to make the detection of heavy metal content more timely. The first detection cycle is determined according to the purification time.

[0075] Among them, the first detection cycle is positively correlated with the purification time, and the positive correlation ratio between the first detection cycle and the purification time is determined by a preset proportional impact compensation parameter; the initial detection cycle is determined according to the time required for the ion exchange resin to reach a preset saturation.

[0076] By recording the purification time and adjusting the first detection cycle accordingly, it is possible to ensure that the resin is tested in time when it is close to saturation, thereby avoiding the risk of excessive heavy metal content. By determining the detection cycle based on the actual purification time, the saturation time of the resin can be predicted more accurately, unnecessary resin replacement can be reduced, and the service life of the resin can be extended. By optimizing the detection cycle, unnecessary detection and resin replacement are reduced, and operating costs are reduced. Automated detection cycle adjustment improves the adaptive ability of the fine mixing acid unit, ensuring the stable operation and water quality safety of the fine mixing acid unit. Reducing the frequency of resin replacement means reducing the amount of waste resin to be processed, which has a positive impact on the environment. Since the first detection cycle is positively correlated with the purification time, the pure water detection device can detect in time when the resin saturation reaches a certain level to ensure water quality. Reasonable detection cycles reduce resource waste and improve economic benefits. The adaptive adjustment of the fine mixing acid unit improves the reliability of the overall operation and reduces the possibility of human error.

[0077] Specifically, based on the first detection cycle, the flow meter detects the pure water flow rate to obtain the actual pure water flow rate. The data analysis module compares the actual pure water flow rate with the preset pure water standard flow rate interval to obtain a first pure water flow rate comparison result. The data analysis module adjusts the opening angle or lifting height of the lifting device according to the first pure water flow rate comparison result.

[0078] The flow meter is set at the drainage outlet of the mixed bed to detect the pure water flow in real time. The data analysis module presets the pure water standard flow range;

[0079] In the first detection cycle, the flow meter starts to detect the actual flow of pure water and transmits the data to the data analysis module in real time. The data analysis module receives the data of the actual flow of pure water and compares it with the preset pure water standard flow range to obtain the first pure water flow comparison result.

[0080] When the comparison result of the first pure water flow rate is that the first pure water flow rate is greater than the maximum value of the standard flow rate interval, the central control module controls the lifting device to open the filter screen to obtain the opening area of ​​the first filter screen, wherein the difference between the first pure water flow rate and the maximum value of the standard flow rate interval determines the opening area of ​​the first filter screen, and the opening area of ​​the first filter screen is positively correlated with the difference between the first pure water flow rate and the maximum value of the standard flow rate interval;

[0081] If the comparison result of the first pure water flow rate is that the first pure water flow rate is within the standard flow rate range, the central control module does not control the lifting device;

[0082] For the case where the comparison result of the first pure water flow rate is that the first pure water flow rate is less than the minimum value of the standard flow rate interval, the central control module controls the lifting device to raise the lifting support rod to obtain the lifting height of the first lifting support rod, and controls the lifting device to open the filter screen to obtain the opening area of ​​the second filter screen, wherein the difference between the minimum value of the standard flow rate interval and the first pure water flow rate determines the opening area of ​​the first filter screen, and the opening area of ​​the second filter screen is positively correlated with the difference between the minimum value of the standard flow rate interval and the first pure water flow rate; the lifting height of the first lifting support rod is positively correlated with the difference between the minimum value of the standard flow rate interval and the first pure water flow rate;

[0083] For example, the standard flow range of pure water is 100-150 liters / minute, and the actual flow rate of pure water detected by the flow meter is 90 liters / minute, which is lower than the preset lower limit of the standard flow range of pure water.

[0084] After receiving this data, the data analysis module determines that it is necessary to raise the lifting support rod and open the filter screen.

[0085] The central control module controls the lifting device to open the filter screen to 120 degrees, and raises the flow meter by 1.5 meters to monitor the adjusted pure water flow until it reaches the standard flow range;

[0086] Among them, the standard flow range of pure water is determined based on historical data and the equipment's ability to treat acidic wastewater.

[0087] For the case where the first pure water flow rate comparison result is that the first pure water flow rate is greater than the maximum value of the standard flow rate interval, the central control module controls the lifting device to open the filter screen to slow down the purification and thus slow down the clean water flow to protect the mixed bed equipment. For the case where the first pure water flow rate comparison result is less than the minimum value of the standard flow rate interval, the central control module controls the lifting device to raise the lifting support rod to obtain the lifting height of the first lifting support rod, and controls the lifting device to open the filter screen to obtain the opening area of ​​the second filter screen, which can change the original precipitation state of the ion exchange resin by lifting the lifting device, so that the gap between the ion exchange resins is increased and the purification capacity is increased. By adjusting the lifting device, the actual flow of pure water is ensured to remain in the preset pure water standard flow range, thereby ensuring the stability of the process and product quality. Through automated control, manual intervention is reduced, production efficiency is improved, and operating costs are reduced. Accurate adjustment is performed according to the actual reading of the flow meter to ensure that the flow rate is within the allowable error range. Real-time monitoring and rapid response can adjust the flow rate in time to avoid production interruptions caused by flow fluctuations. By avoiding damage to the equipment caused by excessive or insufficient flow, the service life of the mixed bed and other related equipment can be extended. Avoids decreased production efficiency or water quality problems due to flow fluctuations.

[0088] Specifically, in the case where adjusting the opening angle and the lifting height of the lifting device cannot satisfy the actual pure water flow rate within the pure water standard flow rate range, the control module controls the lifting device to rotate at the initial rotation speed or replace the ion exchange resin.

[0089] The data analysis module detects through the flow meter that the actual pure water flow rate is still lower than the preset minimum value of the pure water standard flow rate range.

[0090] For example, the flow meter shows a flow rate of 800 liters / minute, while the standard flow range is 100-150 liters / minute.

[0091] The central control module increases the flow rate by adjusting the opening angle and lifting height of the lifting device. However, if these adjustments are ineffective, the central control module will control the lifting support rod to start rotating at an initial rotation speed, which is preset according to the mixed bed parameters to change the distribution state of the ion exchange resin. The flow meter continues to monitor the actual pure water flow rate to obtain the second pure water flow rate. The data analysis module compares the second pure water flow rate with the minimum value of the pure water standard flow rate interval to obtain the second pure water flow rate comparison result.

[0092] When the comparison result of the second pure water flow rate is that the second pure water flow rate is within the pure water standard flow rate range, the central control module does not replace the ion exchange resin in the mixed bed and maintains the current rotation state;

[0093] When the comparison result of the second pure water flow rate is that the second pure water flow rate is less than the minimum value of the pure water standard flow rate range, the central control module replaces the ion exchange resin.

[0094] By adjusting the opening angle and lifting height of the lifting device, it can automatically try to increase the flow rate, reduce manual intervention and improve operating efficiency. When adjusting the opening angle and lifting height is ineffective, the control module changes the distribution state of the ion exchange resin by rotating the lifting device, which helps to improve the distribution of the ion exchange resin and increase the flow rate. The data analysis module continuously monitors the actual pure water flow rate through the flow meter and compares it with the standard flow range, ensuring the real-time feedback and self-adjustment ability of the fine mixing acid unit. If the comparison result of the second pure water flow rate shows that the flow rate has returned to the standard flow range after rotating the lifting device, the central control module will not replace the resin, thereby avoiding unnecessary costs and downtime. If the rotation adjustment still cannot make the flow rate reach the standard, the central control module will trigger the resin replacement program to ensure that the fine mixing acid unit can continue to provide pure water flow that meets the standard. Avoiding unnecessary replacement of ion exchange resins can extend the service life of the resin. The fine mixing acid unit can automatically select the most appropriate adjustment measures according to the actual situation, improving the flexibility of operation.

[0095] Specifically, in the case where the ion exchange resin is not replaced, the data analysis module adjusts the initial opening of the flow rate control valve according to the absolute value of the difference between the initial pure water heavy metal content detected by the pure water detection device and the minimum value of the target pure water heavy metal content range to obtain the target opening of the flow rate control valve.

[0096] The pure water detection device detects the heavy metal content of the pure water to obtain the initial heavy metal content of the pure water, and the data analysis module calculates the absolute value of the difference between the initial heavy metal content and the preset target minimum value of the heavy metal content of the pure water.

[0097] For the case where the comparison result of initial heavy metal content is that the initial pure water heavy metal content is less than the minimum value of the target pure water heavy metal content range, the control module controls the flow rate control valve to increase the opening to obtain the target opening of the flow rate control valve, wherein the absolute value of the difference between the initial heavy metal content and the minimum value of the target pure water heavy metal content and the initial opening of the flow rate control valve determine the target opening of the flow rate control valve, the absolute value of the difference between the initial heavy metal content and the minimum value of the target pure water heavy metal content and the target opening of the flow rate control valve are positively correlated, and the initial opening of the flow rate control valve is determined according to the filling volume and filling density of the ion exchange resin.

[0098] Example 1: If the absolute value of the difference between the initial heavy metal content and the target minimum heavy metal content in pure water is small, it means that the initial heavy metal content in pure water is close to the target minimum heavy metal content in pure water. The data analysis module will instruct the flow rate control valve to maintain a small opening.

[0099] The initial heavy metal content is 0.008 mg / L, and the minimum value of the target pure water heavy metal content is 0.01 mg / L. Then the target opening of the flow rate control valve is 70%, wherein the initial opening of the flow rate control valve is 50%;

[0100] If the absolute value of the difference between the initial heavy metal content and the minimum value of the target pure water heavy metal content is large, it indicates that the initial pure water heavy metal content is far from the target pure water heavy metal content. The data analysis module will instruct the flow rate control valve to increase the opening.

[0101] The initial heavy metal content is 0.003 mg / L, and the minimum value of the target pure water heavy metal content is 0.01 mg / L. The target opening of the flow control valve is 90%, wherein the initial opening of the flow control valve is 50%;

[0102] The pure water detection device monitors the flow rate and heavy metal content of pure water in real time, and feeds the data back to the data analysis module. The data analysis module adjusts the opening of the flow rate control valve according to the feedback data to maintain the heavy metal content of pure water within the target range.

[0103] Example 2: Assuming that the heavy metal content in the initial pure water is 10ppm, and the minimum value of the target pure water heavy metal content range is 5ppm, the data analysis module calculates the absolute value of the difference to be 5ppm. The data analysis module determines that the opening of the flow rate control valve needs to be increased according to the preset algorithm to speed up the flow rate of the acidic wastewater, thereby improving the treatment efficiency of the ion exchange resin. The central control module executes the instructions of the data analysis module and adjusts the opening of the flow rate control valve from 50% to 70%.

[0104] The pure water detection device monitors that the heavy metal content of pure water is gradually decreasing. When the heavy metal content stabilizes at 5ppm, the data analysis module instructs the central control module to maintain the current opening of the flow rate control valve.

[0105] By real-time monitoring and dynamic adjustment of the flow rate of acidic wastewater, ion exchange resins can be used more effectively, the efficiency of heavy metal removal can be improved, and the heavy metal content of the output pure water can be ensured to be stable within the safety standard range, thus protecting the health of end users. By accurately controlling the flow rate of acidic wastewater, unnecessary over-treatment can be avoided, and the use of ion exchange resins and the consumption of chemical reagents can be saved. Reasonable control of the flow rate helps to reduce the wear of the resin and extend its service life. The automation system reduces the need for manual intervention and reduces the risk of operating errors. The real-time monitoring of the pure water detection device and the rapid feedback mechanism of the data analysis module enable the fine mixing acid unit to respond to water quality changes immediately and maintain the stability of the treatment effect. The automatic adjustment process reduces the manual intervention of operators and improves the level of automation. By reasonably adjusting the flow rate, the use of acidic wastewater is optimized and unnecessary consumption is reduced. It is ensured that the heavy metal content of pure water meets the target standard and the quality of the final product is improved. By making the absolute value of the difference between the initial heavy metal content and the minimum value of the target pure water heavy metal content positively correlated with the target opening of the flow rate control valve, it is ensured that the heavy metal content of pure water meets the standard while ensuring the purification efficiency.

[0106] Specifically, in the case of increasing the flow rate of acidic wastewater, the central control module controls the flowmeter to detect the pure water flow at the mixed bed outlet to obtain the first actual pure water flow, and the data analysis unit compares the first actual pure water flow with the preset pure water standard flow range to obtain the second pure water flow comparison result.

[0107] Specifically, the data analysis module determines whether to adjust the initial stirring period according to the comparison result of the second pure water flow rate to obtain a target stirring period;

[0108] The initial stirring period is determined according to the duration from the initial moment of the mixed bed purification of acidic wastewater to the moment when the heavy metal content of pure water is greater than the target heavy metal content of pure water.

[0109] For the case where the comparison result of the second pure water flow rate is that the actual flow rate of the first pure water is less than the minimum value of the pure water standard flow rate interval, based on the initial stirring period, the data analysis module shortens the stirring period according to the absolute value of the difference between the minimum value of the pure water standard flow rate interval and the actual flow rate of the first pure water to obtain the first target stirring period, wherein the first stirring period is inversely proportional to the absolute value of the difference between the minimum value of the pure water standard flow rate interval and the actual flow rate of the first pure water;

[0110] For the case where the comparison result of the second pure water flow rate is that the actual flow rate of the first pure water is within the pure water standard flow rate range, based on the initial stirring period, the data analysis module shortens the stirring period according to the average value of the pure water standard flow rate range to obtain a second target stirring period;

[0111] If the comparison result of the second pure water flow rate is that the actual flow rate of the first pure water is greater than the maximum value of the pure water standard flow rate interval, the data analysis module does not adjust the initial stirring period;

[0112] Example:

[0113] Assume that the actual flow rate of the first pure water is less than the minimum value of the pure water standard flow rate range of 90L / min.

[0114] The data analysis module calculates that the absolute value of the difference between the minimum value of the pure water standard flow range of 100L / min and the actual flow rate of the first pure water of 90L / min is 10L / min.

[0115] The data analysis module shortens the stirring period according to the absolute value of the difference. For example, if the absolute value of the difference is 10 L / min, the stirring period is shortened by 10% to 27 minutes, and a first target stirring period is obtained.

[0116] Assuming that the actual flow rate of the first pure water is within the pure water standard flow rate range [90L / min, 120L / min],

[0117] The data analysis module shortens the stirring period according to the average value of the standard pure water flow interval of 125 L / min, for example, shortens it by 5% to 28.5 minutes, and obtains a second target stirring period;

[0118] Assuming that the actual flow rate of the first pure water, 160 L / min, is greater than the maximum value of the standard flow rate range of pure water, the data analysis module does not adjust the initial stirring period and remains unchanged for 30 minutes.

[0119] By real-time monitoring of the actual pure water flow rate and comparing it with the standard flow rate range, the fine mixing acid unit can adjust the stirring cycle according to the comparison results of the second pure water flow rate, thereby optimizing the purification efficiency of the mixed bed and ensuring that the heavy metal content meets the standard. The data analysis module accurately adjusts the stirring cycle according to the flow rate difference, which helps to achieve more refined operation control and improve the automation level of the system. By shortening the stirring cycle, energy consumption and equipment wear can be reduced while ensuring the treatment effect, and the operating cost can be reduced. Keeping the stirring cycle matching the flow rate helps to maintain the stable operation of the mixed bed and reduce the problem of unstable water quality caused by flow fluctuations. The fine mixing acid unit can automatically adjust the stirring cycle according to different flow conditions to adapt to different treatment requirements and operating conditions. By shortening the stirring cycle, the fine mixing acid unit can respond more quickly to the situation of insufficient actual flow of the first pure water, increase the processing speed, and ensure the heavy metal removal effect. Fine-tuning the stirring cycle helps to maintain the optimal operating state of the system, ensuring water quality while avoiding over-treatment. When the actual flow rate of the first pure water exceeds expectations, keeping the stirring cycle unchanged can ensure that the system will not reduce the treatment effect due to too fast flow.

[0120] Specifically, multiple layers of filter screens are arranged in the filter bin, and the data processing module determines whether to replace the filter screen according to the area of ​​the filter screen covered by the blockage.

[0121] Specifically, in the case of blockage accumulation, the central control module controls the grabbing device to remove the aggregated blockage accumulated in the filter.

[0122] There are three layers of filter screens with different apertures in the filter chamber, which are used to intercept solid particles of different sizes.

[0123] The first filter has the largest pore size and is used to intercept larger particles; the second and third filter pore sizes gradually decrease to further filter smaller particles.

[0124] The imaging device periodically photographs the filter and transmits the image data to the data processing module, which analyzes the coverage area of ​​the blockage on the filter through image recognition technology.

[0125] When the blockage coverage area reaches the preset threshold,

[0126] For example, when the filter area exceeds 30%, the data processing module sends a signal to replace the filter.

[0127] The central control module controls the grabbing device to remove the blockage on the filter screen. The grabbing device includes but is not limited to a rotating brush, a salvaging net and a mechanical arm, which are used to break up and remove stubborn blockages. This embodiment does not specifically limit this.

[0128] After the clearing operation is completed, the grabber collects the blockage into a designated container for subsequent disposal.

[0129] If the blockage cannot be completely removed by the grabbing device, or the filtration efficiency of the filter is significantly reduced, the central control module will issue an instruction to replace the filter.

[0130] For example: the standard flow rate range in the filter chamber is 80L / min-100L / min. If the filter flow meter measures the actual flow rate in the filter chamber to be 60L / min, replace the filter.

[0131] By setting up multiple layers of filters with different apertures, solid particles of different sizes can be effectively intercepted, the overall filtration efficiency can be improved, and the outflow water quality can be ensured to meet the standards. By periodically monitoring the coverage area of ​​the blockage and removing it in time, the filter can be prevented from being over-blocked and its service life can be extended. The coordinated use of the imaging device and the data processing module realizes the automatic monitoring and evaluation of the blockage of the filter, reduces manual intervention, and improves the level of automation. The central control module controls the grabbing device to automatically remove the blockage, which can maintain the normal operation of the filter chamber without stopping the machine, reducing the downtime caused by replacing the filter. By comparing the preset threshold and the actual flow rate, it is possible to accurately determine when the filter needs to be replaced, making the maintenance operation more accurate and efficient. Timely removal of blockages and replacement of filters can effectively prevent the decline of filtration effect and ensure the safety of the final water quality.
