[0126] The return water tank is configured to collect and temporarily store the medium water flowing back from the working face. The hydraulic control switch valve cooperates with the direct return pipeline to form a bypass return channel, so that part of the return water can be directly returned to the medium water tank, realizing fast return and reducing circulation loss. The direct return ball valve and the booster pump are controlled by the electric control system to provide necessary flow control and pressure boost, supporting the direct return of the return water or pushing the water flow to the simple purification station system, to ensure that the return water can be reused smoothly.

[0127] The return water tank system monitors the water volume of the return water tank in real time through the liquid level sensor, and dynamically detects the water quality of the return water through the water quality sensor (such as the conductivity sensor, the pH sensor and the turbidity sensor). The electric control system intelligently analyzes and judges the quality and storage of the return water based on the real-time data collected by these sensors, and automatically determines the return water path: when the water quality is good and the water volume is sufficient, the return water can be directly returned through the bypass pipeline; if the water quality is poor or needs to be purified, the return water is guided into the simple purification station system for treatment before being reused.

[0130] The simple purification electric control assembly can include inlet and outlet pressure sensors and water quality sensors of each level of filtering device. The simple purification station system is used for quickly purifying the poor-quality return water, and the filtering state and the water quality of the outlet water are monitored in real time through the pressure sensors and the water quality sensors, so as to ensure that the return water meets the reuse water quality requirements.

[0143] The central control main station interacts with the ground monitoring platform through a switch, undertakes the control of the water medium control system and the overall management task of the mine water medium treatment system, such as the linkage, management and configuration of each subsystem in the mine water medium treatment system.

[0144] The control method can comprise: detecting the liquid levels of a purified water tank and a main water tank in real time; automatically opening or closing a water inlet ball valve according to the liquid level change of the purified water tank, so as to transport the water produced by a water purification station system into the purified water tank; and automatically opening or closing a water production pump group according to the liquid level change of the purified water tank and the main water tank, so as to transport the water in the purified water tank into the main water tank after being processed by a secondary reverse osmosis system, and ensure the working face water.

[0146] The water production control process: according to the liquid levels of the purified water tank and the main water tank, the water purification station system and the secondary reverse osmosis system are automatically started and stopped to continuously and stably supply high-purity water.

[0147] The water production control process refers to starting or stopping the water supply purification station and the secondary reverse osmosis system according to the liquid levels of the purified water tank and the main water tank, so as to ensure the continuous and stable supply of high-purity water.

[0148] Specifically, when the liquid level of the purified water tank or the main water tank is lower than a set threshold, the system automatically starts the water supply purification station system and the secondary reverse osmosis system to start pretreatment and deep purification of raw water, gradually producing high-purity water meeting the requirements and supplementing the water tank.

In the manual mode, the control process is executed according to the control instructions issued by the central control master station, and in the automatic mode, the control process is automatically executed according to preset parameters.

[0151] The water production control process supports two working modes, namely the manual mode and the automatic mode, so as to meet different operation requirements and operation habits. In the manual mode, the water supply purification station system and the secondary reverse osmosis system can execute start-stop operations according to the control instructions issued by the central control master station, give the operator higher autonomous control authority, allow flexible intervention in the equipment operation state, and facilitate on-site debugging and operation adjustment in special cases. At this time, the start-stop judgment condition is relatively loose, which facilitates rapid response and control by the human. In the automatic mode, the water supply purification station system and the secondary reverse osmosis system automatically complete start-stop judgment and control operations according to the preset process parameters and operation interlocking conditions, so as to realize stable and efficient operation of the water production equipment. The automatic mode relies on real-time monitoring data and set thresholds, can accurately adjust the water production process, ensures the continuity of water supply and the stability of water quality, reduces human intervention, and improves the intelligent level and operation safety of the system. The water production control process provided by the embodiment of the present application supports two modes, which not only guarantees the flexibility and safety of operation, but also realizes intelligent automatic management, so as to meet the water production control requirements in different stages and under different demands.

[0156] Optionally, based on one or more of the embodiments of the control method described above, in another optional embodiment of the present embodiment, the water production pump set is automatically opened or closed according to the change of the liquid levels of the purified water tank and the main water tank, and specifically can include:

[0157] In the automatic mode, if the liquid level of the main water tank is less than or equal to the preset main water production start liquid level threshold, and the liquid level of the purified water tank is greater than or equal to the preset main purified water production start liquid level threshold, the water production pump set is opened to start water production, and until the liquid level of the main water tank is greater than or equal to the preset main water production stop liquid level threshold, or the liquid level of the purified water tank is less than or equal to the preset main purified water production stop liquid level threshold, the water production pump set is closed to stop water production.

[0158] Optionally, based on one or more of the embodiments of the control method described above, in another optional embodiment of the present embodiment, the water production pump set is automatically opened or closed according to the change of the liquid levels of the purified water tank and the main water tank, and specifically can include:

[0159] In the manual mode, in response to a reverse osmosis water production start instruction triggered by a user, when the liquid level of the main water tank is less than the preset main water production stop liquid level threshold, and the liquid level of the purified water tank is greater than the preset main purified water production stop liquid level threshold, the water production pump set is opened to start water production; and in response to a reverse osmosis water production stop instruction triggered by a user, when the liquid level of the main water tank is greater than the preset main water production start liquid level threshold, or the liquid level of the purified water tank is less than the preset main purified water production start liquid level threshold, the water production pump set is closed to stop water production.

[0160] Optionally, the water purification station system can open the water inlet ball valve to start water production when the liquid level of the purified water tank is less than or equal to the preset purified water production start liquid level threshold, and close the water inlet ball valve to stop water production when the liquid level of the purified water tank is greater than or equal to the preset purified water production stop liquid level threshold.

[0161] Specifically, the embodiment of the present application can realize automatic start-stop control of the water supply purification station system based on real-time monitoring of the liquid level in the purification tank through the water supply purification control substation. When the liquid level in the purification tank drops below the preset net water production start liquid level threshold, the water supply purification station system is automatically started to allow raw water to enter the water supply purification station system, start the water production process, start purification and water production, and supplement the water in the tank. As the water supply purification station system continues to run, the liquid level in the purification tank gradually rises. When the liquid level reaches or exceeds the preset net water production stop liquid level threshold, the water inlet ball valve is automatically closed to stop the input of raw water and the water production process, preventing the tank from being overfilled, thereby avoiding resource waste and system overload. Optionally, the preset net water production start liquid level threshold can be 40 cm, and the preset net water production stop liquid level threshold can be 110 cm. Through this closed-loop control method, the water supply purification station system can automatically adjust the working state of the water supply purification station according to the actual water consumption of the purification tank, realize dynamic balance and efficient management of the water supply process, and ensure that the water in the purification tank is neither insufficient nor excessive, ensuring the continuity and stability of water supply.

[0162] Optionally, the embodiment of the present application can start the water production of the secondary reverse osmosis system when the liquid level in the purification tank is greater than or equal to the preset main net water production start liquid level threshold and the liquid level in the main tank is less than or equal to the preset main water production start liquid level threshold, and stop the water production of the secondary reverse osmosis system when the liquid level in the purification tank is less than or equal to the preset main net water production stop liquid level threshold or the liquid level in the main tank is greater than or equal to the preset main water production stop liquid level threshold.

[0163] Specifically, the embodiment of the present application can realize automatic start-stop control of the water supply purification station system based on real-time monitoring of the liquid level in the purification tank through the water supply purification control substation. When the liquid level in the purification tank drops below the preset net water production start liquid level threshold, the water supply purification station system is automatically started to allow raw water to enter the water supply purification station system, start the water production process, start purification and water production, and supplement the water in the tank. As the water supply purification station system continues to run, the liquid level in the purification tank gradually rises. When the liquid level reaches or exceeds the preset net water production stop liquid level threshold, the water inlet ball valve is automatically closed to stop the input of raw water and the water production process, preventing the tank from being overfilled, thereby avoiding resource waste and system overload. Optionally, the preset net water production start liquid level threshold can be 40 cm, and the preset net water production stop liquid level threshold can be 110 cm. Through this closed-loop control method, the water supply purification station system can automatically adjust the working state of the water supply purification station according to the actual water consumption of the purification tank, realize dynamic balance and efficient management of the water supply process, and ensure that the water in the purification tank is neither insufficient nor excessive, ensuring the continuity and stability of water supply.

[0164] Optionally, the preset main product water start-up level threshold can be 60cm, the preset main product water start-up level threshold can be 40cm, the preset main product water stop-up level threshold can be 20cm, and the preset main product water stop-up level threshold can be 110cm.

[0165] This invention, through a closed-loop control process, ensures that the secondary reverse osmosis system always operates under safe, reasonable, and efficient conditions: water production is only started when there is sufficient purified water resources and insufficient high-purity water reserves; and the system is shut down in a timely manner when the water level reaches the upper or lower limit to prevent equipment damage or resource waste, thereby achieving intelligent and automated management of the system.

[0166] As some examples, combined Figure 6 The water tank level line shown is for reference. Figure 7 The present invention provides a logic block diagram of the water production process of a water purification station. In automatic mode, if the water level in the purified water tank is less than or equal to the water production start level, the inlet ball valve is opened; if the water level in the purified water tank is greater than or equal to the water production stop level, the inlet ball valve is closed. In manual mode, if the operator triggers the water purification start knob, and the water level in the purified water tank is less than the water production stop level, the inlet ball valve is opened; if the operator triggers the water purification stop knob, and the water level in the purified water tank is greater than the water production start level, the inlet ball valve is closed.

[0167] As some examples, combined Figure 6 The water tank level line shown is for reference. Figure 8 The present invention provides a logic block diagram of a two-stage reverse osmosis permeate process. In automatic mode, if the water level in the main water tank is less than or equal to the main permeate start level and the water level in the purified water tank is greater than or equal to the main purified permeate start level, the transfer pump unit is controlled to start. If the water level in the main water tank is greater than or equal to the main permeate stop level, or the water level in the purified water tank is less than or equal to the main purified permeate stop level, the transfer pump unit is controlled to stop. In manual mode, if the operator triggers the start knob for the two-stage reverse osmosis permeate, and the water level in the main water tank is lower than the main permeate stop level and the water level in the purified water tank is higher than the main purified permeate stop level, the transfer pump unit is controlled to start. If the operator triggers the stop knob for the two-stage reverse osmosis permeate, and the water level in the main water tank is higher than the main permeate stop level, or the water level in the purified water tank is lower than the main purified permeate stop level, the transfer pump unit is controlled to stop.

[0168] Backwashing control process: Real-time monitoring of the pressure difference between the inlet and outlet of each filter device and the running time; the backwashing process is automatically triggered when the conditions are met.

[0169] The embodiment of the present application can monitor the pressure difference between the water inlet and the water outlet of each filter device in real time. When the pressure difference continuously increases and reaches a preset threshold, it indicates that the filter medium has been blocked by impurities, affecting the smooth flow of water, and backwashing is needed to restore the filtering effect. The running time of the filter device can also be accumulated, and a reasonable time period is set to ensure that the filter device can automatically perform backwashing regularly even if the pressure difference does not reach the threshold, preventing potential blockage risk caused by long-term operation.

[0170] It should be noted that the start of backwashing is not simply dependent on pressure difference and time conditions, but also must consider the running state of the entire mine water medium treatment system, judge the working state of the water medium pump and the liquid level of the purified water tank and the main water tank, to ensure that the normal water supply demand is not affected when backwashing is started, and to avoid water shortage or system pressure instability caused by backwashing. Only when these conditions are met, the backwashing judgment logic is entered, and the backwashing process is automatically triggered according to the set time difference mode (timed washing) or pressure difference mode (pressure difference triggered washing). Subsequently, the cleaning mechanism will perform the corresponding washing action, and the filter medium is flushed by the reverse water flow to remove the blockage and restore the filtering performance.

[0171] The backwashing control process provided by the embodiment of the present application can ensure efficient and stable operation of the filter device, timely remove blockage and impurities in the filter unit through automatic means, prolong the service life of the filter device and ensure stable water quality, and realize intelligent maintenance of the filter device.

[0172] Optionally, if the running time of any filter device of the water supply purification station system reaches the first preset time length or the pressure difference change between the inlet and outlet reaches the first preset pressure difference change threshold, the mine raw water is introduced to backwash the filter device.

[0173] If the running time of any filter device in the water supply purification station system reaches the first preset time length, or the pressure difference between the inlet and outlet increases to the first preset pressure difference change threshold, it indicates that the filter device may be blocked or performance decreased, and the mine raw water is introduced to backwash the filter device to timely remove the blockage and restore the filtering efficiency.

[0174] In actual application, the embodiment of the present application can set different first preset time lengths or first preset pressure difference change thresholds for filter devices at different levels of the water supply purification station system according to the filtering fineness of the filter devices at different levels. For example, the first preset time length of the first-level filter device can be 48 hours, and the first preset pressure difference change threshold can be 1 Mpa. The first preset time length of the second-level filter device can be 36 hours, and the first preset pressure difference change threshold can be 0.5 Mpa. The first preset time length of the third-level filter device can be 24 hours, and the first preset pressure difference change threshold can be 0.5 Mpa.

[0175] Optionally, based on one or more embodiments of the control method described above, another optional embodiment of the control method provided by the embodiments of the present application can further include:

[0176] The differential pressure between the inlet and the outlet of the RO filter water production device is detected in real time, and in the case that the preset backwashing starting condition is met, when the differential pressure between the two sides of the RO filter water production device is greater than a first preset differential pressure threshold, the RO backwashing ball valve is opened to introduce water from the purified water tank to backwash the RO filter water production device, wherein the preset backwashing starting condition is set on the premise of ensuring working surface water.

[0177] Optionally, based on one or more embodiments of the control method described above, another optional embodiment of the control method provided by the embodiments of the present application can further include:

[0178] The running time of the RO filter water production device is counted in real time, and in the case that the preset backwashing starting condition is met, when the running time of the RO filter water production device is greater than a first preset backwashing time threshold, the RO backwashing ball valve is opened to introduce water from the purified water tank to backwash the RO filter water production device, wherein the preset backwashing starting condition is set on the premise of ensuring working surface water.

[0179] Optionally, the preset backwashing starting condition is that no pump in the water medium pump group is running, and the liquid level of the purified water tank is greater than a first preset backwashing liquid level threshold, and the liquid level of the main water tank is greater than a second preset backwashing liquid level threshold.

[0180] Since the RO membrane in the secondary reverse osmosis system needs to be protected, the first preset backwashing time threshold and the first preset differential pressure threshold are more stringent than the requirements for each level of filter device in the water supply purification station system, for example, the first preset backwashing time threshold can be set to 24 hours, and the first preset differential pressure threshold can be set to 0.2 Mpa. The sewage after backwashing is discharged through the sewage valve.

[0181] The backwashing control process provided by the embodiments of the present application has the characteristics of automatic triggering and flexible setting, and the running time and the differential pressure threshold can be adjusted according to the actual operation condition and equipment maintenance requirement, so that the backwashing is timely and effective, and resource waste caused by frequent cleaning is avoided.

[0182] As some examples, in conjunction with Figure 6 the water tank liquid level line shown in FIG. Figure 9The logic block diagram of the backwashing control process provided by the embodiment of the present application firstly judges whether the mine water medium treatment system is in a pump-free operation, and whether the purified water level is greater than the backwashing starting liquid level, and whether the main water tank water level is greater than the backwashing starting liquid level. If yes, the backwashing judgment of the water supply purification station system and the secondary reverse osmosis system can be entered. The water supply purification station system can perform the backwashing process according to the conventional logic, and the backwashing judgment of the secondary reverse osmosis system can firstly judge whether the pressure difference before and after the reverse osmosis filtration is greater than the set pressure difference or whether the backwashing time interval is greater than the preset backwashing interval. If yes, the reverse osmosis backwashing ball valve is opened to perform the backwashing of the RO filtered water device under the condition that the backwashing protection interval is greater than the preset protection interval.

[0183] Under the premise that the liquid levels of the purified water tank and the main water tank meet the requirements, the embodiment of the present application automatically judges whether the backwashing program needs to be started by monitoring the running time of the RO filtered water device and the inlet and outlet pressure difference. The backwashing water source uses the purified water in the purified water tank to ensure the water quality and effect of the backwashing process, thereby realizing the automatic maintenance of the RO filtered water device and the stable operation of the system.

[0184] Water quality circulation control process: according to the liquid level of the main water tank and the circulation time interval of the circulation pump, the circulation pump is automatically started and stopped to return the medium water to the secondary reverse osmosis system for re-purification to prevent water quality deterioration.

[0185] It can be understood that the water stored in the medium water tank and the main water tank is prone to water quality decline, microbial breeding or other pollution if not flowing for a long time. Therefore, the stored medium water is periodically returned to the secondary reverse osmosis system for re-purification through water quality circulation to maintain the high purity and safety of the water body.

[0186] Optionally, on the basis of one or more embodiments of the control method, another optional embodiment of the embodiment of the present application provides that the control method can further include:

[0187] Real-time detection of the running state of the water medium pump set and the liquid level of the main water tank; under the condition that the preset water quality circulation starting condition is met, the circulation pump set is automatically started or stopped according to the running state of the water medium pump set and the liquid level change of the main water tank to return the water stored in the main water tank and the auxiliary water tank to the secondary reverse osmosis system, wherein the preset water quality circulation starting condition is set on the premise of ensuring the working face water.

[0188] In order to ensure the normal operation of the reverse osmosis system and the water tank, the water quality circulation starting needs to meet the main water tank liquid level condition and the circulation time interval condition.

[0189] The main water tank liquid level condition refers to the main water tank liquid level must be higher than a preset circulating pump starting liquid level threshold. In this way, it can be ensured that there is enough water resource in the water tank for circulation, preventing the circulating pump from idling or being damaged due to a too low liquid level, and also ensuring that normal water use is not affected.

[0190] The circulating time interval condition refers to a circulating time interval is preset to ensure that the circulating pump will not be started too frequently even if the liquid level condition is met.

[0191] Optionally, in the case that the liquid level of the main water tank is greater than the preset circulating pump starting liquid level and the circulating time interval of the circulating pump reaches the circulating time, the circulating pump is controlled to circulate, and the circulating time interval is re-timed.

[0192] Specifically, the embodiment of the present application can continuously monitor the liquid level of the main water tank and record the running time interval of the circulating pump. When the liquid level of the main water tank is greater than the preset circulating pump starting liquid level and the circulating time interval reaches the set value, the system automatically starts and stops the circulating pump, and the medium water is returned from the water tank to the secondary reverse osmosis system for re-purification treatment. After the circulating pump is started, the system will re-time and record the time interval of the next circulation, so as to realize periodic circulation.

[0193] The water quality circulation control process provided by the embodiment of the present application automatically controls the start and stop of the circulating pump by real-time monitoring of the liquid level of the main water tank and the running time of the circulating pump, and returns the stored medium water to the secondary reverse osmosis system for re-purification. In this way, it not only prevents the deterioration of water quality due to long-term storage, but also ensures stable system operation, continuous water supply and long-term maintenance of water purity.

[0194] Optionally, the water quality circulation control process provided by the embodiment of the present application supports manual mode and automatic mode. In the manual mode, the control process is executed according to the control instructions issued by the central control master station, and in the automatic mode, the control process is automatically executed according to the preset parameters.

[0195] In the manual mode, the start, stop and other control operations of the water quality circulation are executed by manual intervention, and the operator controls the equipment by issuing specific control instructions through the central control master station.

[0196] In the automatic mode, the water quality circulation control is completely dependent on the pre-set parameters (such as liquid level threshold, circulating time interval, etc.) and is automatically executed without manual intervention.

[0197] Optionally, on the basis of one or more embodiments of the above control method, in another optional embodiment of the embodiment of the present application, the circulating pump group is automatically started or stopped according to the running state of the water medium pump group and the liquid level change of the main water tank, which can specifically include:

[0198] In the automatic mode, if no pump in the water medium pump group is running, and the liquid level of the main water tank is greater than the preset circulating pump start liquid level threshold, and the preset circulating period is reached, the circulating pump group is started to begin water quality circulation.

[0199] Optionally, based on one or more embodiments of the control method described above, another optional embodiment of the present embodiment provides that the circulating pump group is automatically started or stopped according to the running state of the water medium pump group and the change of the liquid level of the main water tank, and specifically can include:

[0200] In the manual mode, in response to a water quality circulation start instruction triggered by a user, when the liquid level of the main water tank is greater than the preset circulating pump stop liquid level threshold and no pump in the water medium pump group is running, the circulating pump group is started to begin water quality circulation; and in response to a water quality circulation stop instruction triggered by a user, the circulating pump group is stopped to stop water quality circulation.

[0201] Optionally, during the water quality circulation, if the running time of the circulating pump group reaches a target circulating stop time point, or the liquid level of the main water tank is less than the preset circulating pump stop liquid level threshold, or a preset circulating stop condition is met, the circulating pump group is stopped to stop water quality circulation, wherein the preset circulating stop condition is that the liquid level of the main water tank is less than the preset backwater start liquid level threshold, and a pump in the water medium pump group is running, and the liquid level of the main water tank decreases by more than a first preset liquid level value within a preset unit time.

[0202] The water quality circulation control process provided by the present embodiment supports switching between two modes, and can flexibly adjust the running mode according to management requirements and running conditions. Generally, the automatic mode is enabled during normal running, and the manual mode is switched in special cases (such as equipment maintenance, fault troubleshooting, and parameter debugging).

[0203] The water quality circulation control process provided by the present embodiment supports two running modes, namely the manual mode and the automatic mode. In the manual mode, an operator issues an instruction through a central control master station to flexibly intervene in the equipment running; and in the automatic mode, the system automatically controls the start and stop of the circulating pump according to preset parameters to ensure that the water quality circulation is stable and efficient.

[0204] It should be noted that the entire water quality circulation process is based on the premise of ensuring normal water use on site, and the state of the water medium pump and the liquid level of the main water tank are key conditions for determining whether to start circulation to prevent the circulation process from affecting daily water supply requirements.

[0205] As some examples, in combination with Figure 6 the water tank liquid level line shown in FIG. 1, and referring to Figure 10The logic block diagram of the water quality circulation dual-mode control process provided by the embodiment of the present application is as follows: in the manual mode, if the operator triggers the start knob of the water quality circulation, the circulation pump starts to circulate when the water level of the main water tank is greater than the stop liquid level line of the circulation pump and the pump is not running; if the operator triggers the stop knob of the water quality circulation, the control stops the circulation pump from running when the circulation pump is in the positive circulation.

[0206] As other examples, in combination with the water tank liquid level line shown in Figure 6 , reference is made to Figure 11 The logic block diagram of the circulation pump circulation control process provided by the embodiment of the present application is as follows: the circulation pump stops running when the circulation time of the circulation pump reaches the target time; the circulation pump stops running when the water level of the main water tank is less than the stop liquid level line of the circulation pump; the circulation pump stops running when the water level of the main water tank is less than the start liquid level line of the backwater, the pump is running, and the water level decreases by a preset threshold value per unit time.

[0207] The backwater treatment control process: based on the liquid level of the backwater tank and the real-time parameters of the water quality sensor, it is determined whether the backwater path is the backwater direct return path or the backwater reuse path, and the direct return ball valve and the booster pump are coordinated to control the backwater scheduling.

[0208] Specifically, the embodiment of the present application can determine the treatment path of the backwater according to the real-time monitored water quality parameters and liquid level information. When the backwater quality meets certain standards (such as good water quality, conductivity, pH, and turbidity within the allowable range) and the liquid level meets the demand, the backwater can be directly returned to the auxiliary water tank, realizing the rapid reuse of water resources and reducing the treatment cost. When the backwater quality does not meet the standards (such as high conductivity, abnormal pH, or large turbidity), the system guides the backwater to the simple purification station for deep treatment before reuse, so as to ensure the safety and stability of the water supply quality.

[0209] Optionally, on the basis of one or more embodiments of the above control method, in another optional embodiment of the embodiment of the present application, the control method can further include:

[0210] Real-time detection of the liquid level of the main water tank and the backwater tank; under the condition that the preset backwater starting condition is met, the backwater channel is determined to be the backwater direct return path or the backwater reuse path according to the change of the liquid level of the main water tank, the change of the liquid level of the backwater tank, and the backwater quality, and the backwater scheduling is performed through the backwater channel, wherein the preset backwater starting condition is set on the premise of ensuring the working face water.

[0211] Optionally, based on one or more of the embodiments of the control method described above, in another optional embodiment of the embodiments of the present application, according to the change of the liquid level of the main water tank, the change of the liquid level of the liquid return tank and the water quality of the return water, it is determined whether the return water channel is a return water direct return path or a return water reuse path, and the return water is dispatched through the return water channel, which can specifically include:

[0212] In the case that the liquid level of the main water tank is greater than or equal to the preset return water start liquid level threshold, it is determined whether the water quality of the return water meets the first preset direct return water quality condition, if yes, it is determined that the return water channel is a return water direct return path, the booster valve is closed, the direct return ball valve is opened, and the return water in the liquid return tank is transported to the auxiliary water tank through the direct return pipeline, and if no, it is determined that the return water channel is a return water reuse path, the direct return ball valve is closed, and the booster valve is automatically opened or closed according to the change of the liquid level of the liquid return tank, so as to transport the return water in the liquid return tank to the simple purification station system for treatment.

[0213] Optionally, the return water treatment control process provided by the embodiments of the present application supports a manual mode and an automatic mode, in the manual mode, the control process is executed according to the control instruction issued by the central control master station, and in the automatic mode, the control process is automatically executed according to the preset parameters.

[0214] In the manual mode, the operator directly specifies the return water path through the central control master station. In the automatic mode, the return water path is automatically selected according to the preset parameters and the determination logic, and the working state of the direct return ball valve and the booster pump is controlled without manual intervention.

[0215] Optionally, based on one or more of the embodiments of the control method described above, in another optional embodiment of the embodiments of the present application, the booster valve is automatically opened or closed according to the change of the liquid level of the liquid return tank, which can specifically include:

[0216] In the automatic mode, if the liquid level of the liquid return tank is greater than or equal to the preset liquid return high liquid level threshold, the booster valve is opened, and the return water is dispatched through the return water reuse path, until the liquid level of the liquid return tank is less than the preset liquid return low liquid level threshold, the booster valve is closed.

[0217] In the automatic mode, if the liquid level of the main water tank drops rapidly, it indicates that the water supply pressure is large, the return water directly takes the direct return path, the water quantity of the main water tank is preferentially supplemented, and the continuity of water supply is ensured. If the liquid level of the main water tank is stable, the water quality parameters (such as electrical conductivity) of the return water are further detected. If the electrical conductivity is higher than the set value (such as 27 us / cm): it is determined that the water quality of the return water is not up to standard, the return water reuse path is entered, that is, the return water is guided to the simple purification station for treatment. If the electrical conductivity is lower than the set value: the water quality of the return water is up to standard, the direct return path is directly selected, and the rapid reuse of water resources is realized. The direct return ball valve is automatically opened or closed according to the path instruction automatically determined by the system. The direct return ball valve is opened in the direct return mode, and the ball valve is closed or switched to the purification station in the reuse mode.

[0218] Optionally, based on one or more of the embodiments of the control method described above, in another optional embodiment provided by the embodiments of the present application, the booster valve is automatically opened or closed according to the change of the liquid level of the liquid return tank, which can specifically include:

[0219] In the manual mode, in response to a user-triggered water return scheduling start instruction, when the liquid level of the liquid return tank is greater than the preset low liquid level threshold, the booster valve is opened, and water return scheduling is performed through the water return reuse path; in response to a user-triggered water return scheduling stop instruction, when the liquid level of the liquid return tank is less than the preset high liquid level threshold, the booster valve is closed.

[0220] Optionally, based on one or more of the embodiments of the control method described above, in another optional embodiment provided by the embodiments of the present application, before real-time detection of the liquid levels of the main water tank and the liquid return tank, the control method can further include:

[0221] Real-time detection of the water quality of the mine raw water; determining whether the water quality of the mine raw water meets the second preset direct water return quality condition, if yes, determining that the water return channel is the water return direct return path, closing the booster valve, opening the direct return ball valve, and transporting the water in the liquid return tank to the auxiliary water tank through the direct return pipeline, if not, performing the step of real-time detection of the liquid levels of the main water tank and the liquid return tank.

[0222] Optionally, based on one or more of the embodiments of the control method described above, in another optional embodiment provided by the embodiments of the present application, the control method can further include:

[0223] Performing state detection and control on the direct return ball valve in the system power-on initialization stage, to ensure that at least one of the water return direct return path and the water return reuse path is opened, so as to prevent water return blockage caused by action failure.

[0224] It should be noted that the direct return ball valve is a key control element in the water return path, responsible for opening or closing different channels (water return direct return path and water return reuse path) of the water return. At least one water return channel is kept unblocked to ensure smooth flow of water return. The direct return ball valve will usually maintain the last state (i.e., the open or closed state) before power-off after power-off, and will not automatically switch to a default open state. In order to avoid water return path blockage caused by the direct return ball valve not being opened or action failure after system power-on, state detection must be performed on the direct return ball valve in the power-on initialization stage to ensure reliable establishment of the water return path.

[0225] As some examples, reference is made to Figure 12 A logic block diagram of the direct return ball valve opening process provided by the embodiments of the present application, when the direct return ball valve is opened, the opening feedback is detected, if it is detected that the direct return ball valve has been opened, the water return channel is recorded as the water return direct return path, if the feedback times out, the direct return ball valve is recorded as abnormal, and the direct return ball valve closing process is performed.

[0226] As some examples, refer to Figure 13 The application provides a logic block diagram of a closing process of the straight-return ball valve. In the closing process of the straight-return ball valve, the closing feedback is detected, the backwater channel is recorded as a backwater reuse path, and if the feedback is overdue, a ball valve fault alarm is performed.

[0227] Optionally, the application can determine whether the liquid level of the main water tank decreases by more than a preset liquid level value within a preset unit time. If yes, the backwater straight-return path is entered, i.e., the straight-return ball valve is opened, and the backwater is returned to the auxiliary water tank through the straight-return pipeline. If no, the backwater quality is determined to enter the backwater straight-return path or the backwater reuse path. If the backwater reuse path is entered, the booster pump is started to guide the backwater to the simple purification station system for processing and then to the auxiliary water tank when the liquid level of the backwater tank is greater than or equal to a preset backwater high liquid level threshold value, until the liquid level of the backwater tank is less than a preset backwater low liquid level threshold value.

[0228] Specifically, the application can detect the decrease speed of the liquid level of the main water tank within a unit time to determine whether the water supply is tight. If the liquid level decreases by more than a preset liquid level value, it indicates that the water supply pressure of the main water tank is large, and the water quantity needs to be quickly supplemented. At this time, the backwater straight-return path is selected, i.e., the straight-return ball valve is started, the straight-return pipeline is opened, and the backwater is directly returned to the auxiliary water tank to quickly respond to the water supply demand. If the liquid level does not decrease by more than a preset liquid level value, it indicates that there is no need for emergency water supplement. At this time, the backwater straight-return path or the backwater reuse path can be selected according to the water quality. The backwater reuse path is that the backwater is first sent to the simple purification station for processing and then to the auxiliary water tank to improve the water quality and realize recycling.

[0229] In the backwater reuse path, the application automatically controls the start and stop of the booster pump according to the liquid level of the backwater tank. When the liquid level of the backwater tank is greater than or equal to a preset backwater high liquid level threshold value, the booster pump is started to pressurize the backwater and send it to the simple purification station for deep processing and then to the auxiliary water tank. In this way, the backwater conveying power can be guaranteed, and the water quality can be improved. When the liquid level of the backwater tank decreases to a preset backwater low liquid level threshold value, the booster pump is stopped to avoid pump idling or air suction caused by the low liquid level of the water tank. Optionally, the preset backwater high liquid level threshold value can be set to 60 cm, and the preset backwater low liquid level threshold value can be set to 20 cm.

[0230] As some examples, refer to Figure 14The logic block diagram of the liquid return pump action control provided by the embodiment of the present application is as follows: in the direct return mode, the liquid return pump that plays a role of pressure boosting is closed; in the return reuse mode, if it is an automatic mode, the liquid return pump is opened when the liquid level in the liquid return tank is greater than or equal to the high liquid level line, and the liquid return pump is closed when the liquid level in the liquid return tank is less than or equal to the low liquid level line; if it is a manual mode, the liquid return pump is opened when the liquid level in the liquid return tank is greater than the low liquid level line under the condition that the operator triggers the start knob of the liquid return pump, and the liquid return pump is closed when the liquid level in the liquid return tank is less than the high liquid level line under the condition that the operator triggers the stop knob of the liquid return pump.

[0231] In the return water treatment process, the embodiment of the present application intelligently determines the return water path according to the change speed of the main water tank liquid level: if the water supply pressure is large, the water is directly returned, and if the water supply pressure is stable, the return reuse path is selected. In the reuse path, the start and stop of the booster pump are automatically controlled by the liquid level in the liquid return tank, the pump is started when the liquid level is high, and the pump is stopped when the liquid level is low, so as to ensure that the return water is smoothly sent to the simple purification station for deep treatment and finally delivered to the auxiliary water tank, and the safe, efficient and intelligent management of water resources is realized.

[0232] As some examples, in combination with Figure 6 the water tank liquid level line shown in Figure 15 The logic block diagram of the return water treatment control process provided by the embodiment of the present application can enter the direct return mode when the liquid level in the main water tank is less than the liquid level line for starting return water, there is pump operation, and the number of times that the water level drops by a preset threshold value in a unit time reaches twice, and any condition is not met, the return water channel record is detected, and the corresponding process is executed according to the return water channel record.
