Description

Technical Field

[0001] The present invention relates to the field of biological fermentation technology, and in particular to a waste liquid treatment system for a fermentation tank sampling port with multi-mode vacuum suction and intelligent flushing. Background Art

[0002] In the bio-fermentation process, the waste liquid treatment system at the sampling port is a key facility to ensure the sanitation of the production environment. The currently commonly used gravity-fed discharge device, which relies on the deadweight of the waste liquid to achieve fluid transportation in the pipeline, has many technical limitations:

[0003] On the one hand, the flow rate of the fluid in gravity-driven mode is limited by the vertical height difference of the pipeline, making it difficult to increase the flow rate of the medium during the discharge process. Especially when treating high-viscosity fermentation wastewater, the stagnation effect makes the wastewater prone to persistent adhesion in the conical section of the sampling funnel and the transition zone of the pipeline, creating a material foundation for microbial growth.

[0004] On the other hand, frequent manual flushing operations are required to maintain pipeline cleanliness, which not only consumes a lot of manpower, but also poses the risk of biological contamination spread due to liquid splashing during flushing. Furthermore, the current manual flushing operations lack standardized control methods. Especially in open operation scenarios, the splashing caused by water impact can easily cause secondary contamination. The uncontrollable factors in this operation process also increase the potential risk of personnel exposure to pollutants. At the same time, the traditional flushing mode requires a large amount of water or disinfectant, cannot achieve precise control on demand, and increases the workload of sewage treatment.

[0005] Due to the effects of the above-mentioned technical defects, the existing gravity-fed waste liquid treatment system faces severe challenges in terms of operational reliability, health and safety, and resource utilization efficiency. Especially in large-scale continuous production scenarios, it is urgent to develop new treatment solutions to break through technical bottlenecks. Summary of the Invention

DETAILED DESCRIPTION

[0074] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0075] like Figure 1As shown, an embodiment of the present invention proposes a multi-mode vacuum suction and intelligent flushing fermentation tank sampling port 1 waste liquid treatment system, comprising: a receiving and diversion component, configured to receive and divert sampling waste liquid and flushing medium, and implement liquid level monitoring; a vacuum suction component, configured to generate a gradient-adjustable suction driving force; a multi-media flushing component, configured to provide a variety of flushing media, and implement flow monitoring; an interlocking pressure stabilizing component, including a waste liquid collection tank and a vacuum buffer tank, the waste liquid collection tank is configured to implement temporary storage of waste liquid and pressure and liquid level monitoring in the tank, and the vacuum buffer tank is configured to coordinately regulate vacuum suction The suction output air pressure of the suction component; the collaborative controller 8 is configured to: respond to at least one input of the liquid level exceeding limit signal, the timing signal and the manual instruction, and dynamically allocate control resources according to the priority arbitration rules; control the vacuum suction component to perform the suction operation, and simultaneously discharge the waste liquid collection tank for liquid level exceeding limit and / or vacuum pressure compensation, and control the vacuum buffer tank to absorb air pressure fluctuations based on the target vacuum degree; after the suction is completed, start the multi-media flushing component according to the preset medium sequence, and perform adaptive flushing work including medium selection, stepless adjustment of the injection pressure and closed-loop control of the medium usage.

[0076] The present invention uses a receiving and diversion component to receive and divert waste liquid and flushing medium in real time, and combines it with the dynamic liquid level monitoring function to provide precise input for automatic control; at the same time, the gradient-adjustable suction driving force generated by the vacuum suction component significantly improves the waste liquid discharge efficiency, ensures that the waste liquid is discharged quickly and thoroughly, and effectively avoids the problems of waste liquid residue and pipe adhesion caused by insufficient flow rate in the traditional gravity self-flow method.

[0077] Secondly, the multi-media flushing component achieves precise adjustment of the amount of flushing liquid through multi-media switching and flow closed-loop control, overcomes the disadvantages of excessive use of cleaning liquid or disinfectant in manual flushing, and reduces resource consumption and sewage treatment load; when it works in coordination with the interlocking voltage stabilizing component, the liquid level-pressure dual-parameter interlocking verification mechanism of the waste liquid collection tank can simultaneously execute liquid level over-limit waste discharge and vacuum pressure compensation, and the air pressure fluctuation absorption control of the vacuum buffer tank further ensures system stability and avoids the risk of equipment damage caused by sudden pressure changes.

[0078] Furthermore, the collaborative controller 8 dynamically allocates control resources based on priority arbitration rules, responds to multi-mode inputs such as liquid level exceeding the limit, timing signals and manual instructions, and automatically triggers the adaptive flushing process of the multi-media flushing component after the suction is completed.

[0079] Therefore, the present invention takes full-process automated control as its core, and through efficient interlocking and adaptive parameter adjustment between components, it significantly reduces the intensity of manual operation and the risk of secondary pollution while improving the efficiency of waste liquid treatment, thus achieving both process reliability and resource economy.

[0080] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0081] Furthermore, the receiving and guiding assembly includes: a funnel assembly 2, which is made of corrosion-resistant material, and the funnel assembly 2 has a guiding function, an inclined guiding surface, and the bottom inclined guiding surface is sealedly connected to the inlet end of the vacuum suction assembly, and an anti-backflow baffle is provided at the end of the inclined guiding surface; a liquid level monitoring unit 3, which is arranged on the funnel assembly 2, and includes an ultrasonic liquid level meter, a radar liquid level meter, a differential pressure liquid level meter, a tuning fork liquid level meter and a float liquid level meter.

[0082] Next, the vacuum suction assembly includes: a vacuum pipe network, a pressure control valve group and a vacuum unit 7. The following are detailed introductions:

[0083] The vacuum pipe network, with a multi-branch topology, connects the diversion outlet of the diversion assembly, the flushing medium injection port of the multi-media flushing assembly, the waste liquid input port of the waste liquid collection tank, and the pressure balancing port of the vacuum buffer tank, forming a closed-loop pressure control path. Preferably, the waste liquid flow rate in the vacuum pipe network is ≥1.5 m / s.

[0084] Also refer to Figure 1 , pressure control valve group, the control valve group includes: solenoid valves, pneumatic valves, electric valves and other types of valves, specifically including:

[0085] The monitoring node valve 1# is set at the connection between the diversion outlet and the vacuum pipe network, and is configured to open during the suction stage to establish a waste liquid diversion path.

[0086] Flushing medium isolation valves 6#, 7#, and 8# are arranged at the intersection of the flushing medium injection end and the vacuum pipeline network, and are configured to open during the flushing stage to establish a medium diversion path.

[0087] The waste liquid collection tank vacuum input valve 3# is arranged at the connection between the waste liquid input interface of the waste liquid collection tank and the vacuum pipe network, and is configured as follows: in the suction stage, in response to the control instructions of the collaborative controller 8, it executes control to adjust the vacuum degree of the waste liquid tank; in the flushing stage, it switches to a closed state to isolate the communication path between the flushing medium and the vacuum buffer tank.

[0088] The waste liquid collection tank unloading valve 4# is arranged at the sampling waste output end of the waste liquid collection tank and is configured to perform the operation of discharging the waste liquid in the tank.

[0089] The waste liquid collection tank pressure relief valve 2# is arranged at the air pressure output end of the waste liquid collection tank and is configured to perform the operation of adjusting the vacuum air pressure in the tank.

[0090] The vacuum unit control valve 5# is set at the connection between the vacuum unit 7 and the vacuum pipeline network, and is configured to dynamically adjust the vacuum degree of the buffer tank.

[0091] In addition, a buffer tank pressure regulating valve is provided, which is arranged at the pressure balance port of the vacuum buffer tank and is configured to perform vacuum degree adjustment based on a dynamic pressure interlock mechanism.

[0092] The vacuum unit 7 is arranged at the end of the vacuum pipeline network and is configured to respond to the control instructions of the collaborative controller 8 through the unit start-stop and / or gradient frequency regulation mechanism, dynamically adjust the system vacuum degree, form a chain control with the waste liquid collection tank and the buffer tank pressure regulating valve, and achieve closed-loop pressure balance through the unit start-stop and / or dynamic matching of suction power.

[0093] Then, the multi-media flushing component includes: a multi-media switching valve group 5, which is provided with one or multiple parallel flushing medium input pipelines, and each flushing medium input pipeline is provided with an automatic valve array, and the automatic valve array is configured to perform flushing medium selection and disturbance-free switching based on the preset medium priority; a fan-shaped wide-angle atomizing nozzle 4, which is connected to the automatic valve array of each flushing medium input pipeline, and the injection pressure is dynamically steplessly adjustable in the range of 0.2-0.6MPa, the injection angle is ≥70°, and the coverage area of the inner wall of the funnel is ≥75%; a multi-type flow monitoring unit 10, which is arranged at the connection between the flushing medium input pipeline and the vacuum suction component, including a mass flowmeter, an electromagnetic flowmeter, a vortex flowmeter, an orifice flowmeter and a rotor flowmeter.

[0094] It should be understood that the collaborative controller 8 (such as a single chip microcomputer, PLC, DCS, etc.) has built-in multi-mode control logic (different modes such as timing, liquid level triggering, manual jogging, etc., which can be used separately or in combination), such as Figure 2 As shown, for the status of the above components, the collaborative controller 8 performs the following steps:

[0095] S1. In response to at least one input of a liquid level over-limit signal, a timing signal, and a manual instruction, dynamically allocate control resources according to a priority arbitration rule.

[0096] Furthermore, if Figure 3 As shown, step S1 includes:

[0097] S11. When a liquid level exceeding limit signal is received, the current non-liquid level triggering task is immediately interrupted, a task queue is generated based on the priority arbitration rule, and the liquid level triggering mode is activated first, and the suction and flushing stage is automatically entered.

[0098] It should be emphasized that the priority arbitration rules include: when the liquid level over-limit signal conflicts with the timing signal, the liquid level trigger mode is executed first and the timing task is delayed until the current operation is completed; during the execution of the manual intervention mode, the automatic response of the liquid level trigger and timing signal is suspended until the system is reset to the automatic control state.

[0099] S12. When a timing signal is received and there is no liquid level trigger signal, the timing working mode is activated, and the suction and flushing stages are forcibly started according to the preset cycle. Among them, the suction process of the timing working mode gives priority to emptying the current waste liquid, and the suction time is dynamically compressed with the real-time liquid level. The flushing process of the timing working mode gives priority to switching the disinfection medium and performing quantitative supply control.

[0100] S13. When a manual instruction is received, the manual intervention mode is activated, the automatic control logic is isolated through the mutual exclusion lock mechanism, and the suction and flushing stage is entered after the safety check is passed. Among them, a temporary override interface for the medium priority is provided to dynamically reload the preset medium sequence.

[0101] In a specific embodiment, the collaborative controller 8 is deployed with three working modes, and multi-modal collaborative control is achieved through priority arbitration rules and dynamic task scheduling. Specifically:

[0102] (1) Liquid level trigger mode: The liquid level trigger mode detects the liquid level status of the funnel assembly 2 in real time through the liquid level monitoring unit 3, and triggers the automatic control program when the liquid level exceeds the preset threshold. The specific execution process includes: after the controller receives the liquid level signal, it starts the vacuum suction unit (the vacuum unit 7 frequency conversion accelerates to the initial set frequency, and the vacuum buffer tank pressure is maintained at the set value); the waste liquid is quickly discharged into the waste liquid collection tank through the vacuum suction pipe 6, and the suction time is feedback controlled by the flow monitoring unit 10; after the suction is completed, the multi-media switching valve group 5 automatically switches to the preset flushing medium (such as purified water), the atomizing nozzle 4 starts, and the flushing time is 5 to 15 seconds (adjustable); the system resets and enters the standby state, waiting for the next liquid level trigger; and abnormal handling: if the liquid level monitoring fails, the system triggers an alarm and switches to the timing mode as a redundancy guarantee.

[0103] (2) Timing working mode: The timing working mode supports setting cycles according to production batches or process requirements (such as every 2 hours or after each batch), with a minimum time interval of 10 minutes (adjustable). The specific execution process includes: the controller sends instructions according to the preset cycle to force the start of the "suction + flushing" process, which is not limited by the current liquid level; during the suction stage, the current waste liquid is emptied first. If the liquid level is lower than the threshold, the suction time is shortened (such as 5 seconds) to ensure the cleanliness of the pipeline; during the flushing stage, disinfectant (such as sodium hypochlorite solution) can be used to enhance sterilization, or tap water and other media can be used. The amount is quantitatively controlled by the flow monitoring unit 10 (such as 50 to 100 mL per time). Priority adjustment: If the timing mode conflicts with the liquid level trigger mode, the liquid level trigger is executed first, and the timing task is automatically postponed.

[0104] (3) Manual Intervention Mode: The manual intervention mode triggers a single operation through the HMI interface or physical button, which is used for emergency cleaning or debugging. Its safety design and implementation process include: Double safety verification: Before operation, the button must be pressed for 3 seconds and the password must be verified. At the same time, the system automatically detects the status of the waste liquid collection tank (the liquid level is below the upper limit and the pressure is normal). If any of the conditions are not met, the system will not be started; Medium priority override: allows the operator to temporarily switch the flushing medium (such as switching to deionized water). The execution process is consistent with the liquid level trigger mode; Automatic reset: After completion, the system resets to the automatic control state and restores the original medium sequence.

[0105] The above-mentioned mode coordination mechanism: The above three modes can run in parallel through the controller logic. The specific coordination rules include: 1) During the operation of the timing mode, if the liquid level trigger condition is met, the control right is immediately seized to execute the liquid level task, and the original timing task is added to the queue and delayed; 2) After the manual intervention mode is activated, the automatic response of the liquid level and timing signals is suspended through the mutex lock until the manual operation is completed and the system is reset; 3) The current parameters (such as medium sequence, timing cycle, frequency setting value) are automatically saved when the mode is switched to avoid data loss.

[0106] S2. Control the vacuum suction component to perform the suction operation, and simultaneously discharge the waste liquid collection tank when the liquid level exceeds the limit and / or compensate for the vacuum pressure, and control the vacuum buffer tank to absorb the pressure fluctuation based on the target vacuum degree.

[0107] Furthermore, if Figure 4 As shown, step S2 includes:

[0108] S21. During the suction phase, a liquid level-pressure dual-mode interlocking check is performed based on the acquired liquid level data and vacuum pressure data of the waste liquid collection tank to determine the liquid level and vacuum pressure status of the waste liquid collection tank.

[0109] S22: In response to at least one of the liquid level exceeding the limit or the vacuum pressure being abnormal in the waste liquid collection tank, activate the corresponding valve group to perform the liquid level exceeding limit waste discharge or vacuum pressure compensation operation.

[0110] Among them, such as Figure 5 As shown, step S22 includes:

[0111] S221. When it is detected that the liquid level of the waste liquid collection tank is higher than the preset liquid level range, the vacuum pressure compensation operation of the waste liquid collection tank is suspended, the monitoring node valve and the waste liquid collection tank vacuum input valve are closed, the waste liquid collection tank pressure relief valve is opened to perform pressure relief operation on the waste liquid collection tank, and after the pressure returns to zero, the waste liquid collection tank unloading valve is started to discharge the waste liquid in the tank.

[0112] S222. When it is detected that the liquid level of the waste liquid collection tank is lower than the preset liquid level parameter range, the waste liquid collection tank pressure relief valve is closed to stop discharging waste liquid, the monitoring node valve and the waste liquid collection tank pressure relief valve are closed, the waste liquid collection tank vacuum input valve is opened, and the vacuum pressure compensation operation of the waste liquid collection tank is restarted until the vacuum degree in the waste liquid collection tank is increased to the preset vacuum degree range.

[0113] S223. When it is detected that the vacuum pressure of the waste liquid collection tank is lower than the preset vacuum pressure range, close the monitoring node valve, the waste liquid collection tank pressure relief valve and the waste liquid collection tank unloading valve, and restart the waste liquid collection tank vacuum input valve to rebuild the vacuum degree in the waste liquid collection tank until it returns to the preset vacuum pressure range.

[0114] S224: When it is detected that the vacuum pressure of the waste liquid collection tank is higher than the preset vacuum pressure range, the vacuum input valve of the waste liquid collection tank is closed.

[0115] S225. When the liquid level and pressure are both within the corresponding preset range, close the waste liquid collection tank pressure relief valve, the waste liquid collection tank vacuum input valve and the waste liquid collection tank unloading valve, open the receiving monitoring node valve to perform waste liquid suction, and after the suction is completed, delay the closing of the receiving monitoring node valve and wait for the next instruction.

[0116] In another specific embodiment, the controller performs a dual-parameter interlocking check by comparing the liquid level detection value (LT01-V001) with the pressure detection value (PT01-V001) in real time. The specific process is as follows:

[0117] (1) Liquid level abnormality handling:

[0118] 1) When the liquid level detection unit (LT01-V001) detects that the liquid level in the waste liquid collection tank is higher than the set range, the vacuum pressure compensation operation is suspended, and the controller immediately performs the following operations: close valves 1# and 3# to isolate the waste liquid input, open valve 2# to relieve the pressure of the waste liquid collection tank; when the pressure returns to zero, start valve 4# and link the discharge pump (if equipped) to remove the waste liquid in the tank; after the liquid level returns to the normal range, close valve 4# and restart the pressure control program.

[0119] 2) Liquid level exceeds the limit (low): When the liquid level detection value is lower than the set range, the controller executes: close the 4# control valve to stop draining, close the 1# and 2# valves to close the pressure relief path; open the 3# valve and restart the suspended vacuum pressure compensation operation, and increase the vacuum degree in the tank to the set range through the vacuum unit 7.

[0120] 3) When the liquid level detection value LT01-V001 and the pressure detection value PT01-V001 are both within the set range, close valves 2#, 3#, and 4#, open valve 1#, suck the waste liquid in the funnel into the waste liquid collection tank, delay closing valve 1#, and wait for the next start command.

[0121] This embodiment fully covers the abnormal handling and steady-state operation requirements of the waste liquid collection tank through liquid level-pressure dual-mode verification and multi-valve coordinated control, meeting the high reliability requirements of industrial scenarios.

[0122] S23 , based on the vacuum detection value of the vacuum buffer tank obtained, start and stop the vacuum unit 7 and / or adjust the output frequency of the vacuum unit 7 of the vacuum suction component through frequency conversion to maintain the target vacuum degree.

[0123] Among them, such as Figure 6 As shown, step S23 includes:

[0124] S231. When it is detected that the vacuum detection value of the vacuum buffer tank is lower than the preset vacuum detection range, the vacuum unit control valve is opened, and the vacuum unit 7 is started and stopped and / or the frequency of the vacuum unit 7 is increased to the vacuum detection range based on the frequency conversion rule.

[0125] S232. When it is detected that the vacuum detection value of the vacuum buffer tank is higher than the set parameter range, the vacuum unit control valve is closed, the vacuum unit 7 is started and stopped and / or the frequency of the vacuum unit 7 is reduced to the vacuum detection range based on the frequency conversion rule, and the vacuum unit 7 is closed after a delay of the set period.

[0126] Among them, the frequency conversion rules of the vacuum unit 7 include: when the pressure fluctuation of the vacuum buffer tank exceeds ±5%, the compensation level of the frequency of the vacuum unit 7 is matched in real time according to the direction of the pressure deviation; when the pressure stabilizes at the target vacuum threshold, the frequency of the vacuum unit 7 is reduced to the preset minimum operating frequency required by the vacuum unit 7.

[0127] In another specific embodiment, the vacuum buffer tank pressure control logic is as follows: When the vacuum detection value of the vacuum buffer tank falls below the set parameter range, vacuum unit control valve 5# is opened, turning on and increasing the frequency conversion of vacuum unit 7 until the vacuum detection value of the vacuum buffer tank rises to the set parameter range; when the vacuum detection value of the vacuum buffer tank rises above the set parameter range, vacuum unit control valve 5# is closed, the frequency conversion of vacuum unit 7 is reduced, and a delayed shutdown of vacuum unit 7 is initiated. This achieves energy-saving logic optimization: the frequency conversion of vacuum unit 7 is dynamically adjusted according to the buffer tank pressure: when the pressure approaches the set value, the frequency drops below the minimum operating frequency required by vacuum unit 7; if the pressure fluctuation exceeds ±5%, the frequency is automatically compensated.

[0128] S3. After the suction is completed, the multi-media flushing component is started according to the preset medium sequence to perform an adaptive flushing operation including medium selection, stepless adjustment of the injection pressure and closed-loop control of the medium dosage.

[0129] Furthermore, if Figure 7 As shown, step S3 includes:

[0130] S31. Switch the flushing medium type based on a preset medium priority sequence, where the medium sequence includes tap water, purified water, deionized water, and disinfectant in sequence, in a reverse order combination, or in a pre-specified order combination.

[0131] S32 , dynamically adjusting the spray pressure of the fan-shaped wide-angle atomizing nozzle 4 to the range of 0.2-0.6 MPa according to the feedback of the liquid level monitoring, and achieving a spray angle of ≥70° and a coverage area of ≥75% of the cleaning by the fan-shaped wide-angle atomizing nozzle 4 .

[0132] S33 , based on the fed-back flow monitoring data, the medium supply amount is adjusted by opening and closing and / or opening degree compensation of the multi-media switching valve group 5 .

[0133] It should be emphasized that the embodiment of the present invention also provides the following two optimization settings:

[0134] (1) Vacuum suction anti-adhesion control: The pipeline flow rate is dynamically maintained through variable frequency regulation of the vacuum unit 7. If the vacuum degree is lower than the threshold, the controller automatically increases the frequency of the vacuum unit 7 and triggers the self-cleaning program of the pipeline inner wall (short-term high-pressure flushing).

[0135] (2) Atomization anti-splashing logic: Atomization anti-splashing flushing: Using a fan-shaped atomizing nozzle 4 (spray angle ≥ 70°), the pressure is steplessly adjustable from 0.2-0.6MPa, covering ≥ 75% of the funnel inner wall area, to achieve splash-free cleaning. The splashing risk can be monitored in real time during the flushing phase (including but not limited to through cameras or sonar sensors). If splashing is detected, the pressure is immediately reduced and an alarm is issued.

[0136] Specifically, refer to Figure 8It can be seen that the method for realizing the dynamic stepless adjustment range of the cleaning medium injection pressure to 0.2-0.6MPa includes the following collaborative methods:

[0137] (1) For the flushing medium delivery pipeline where the flushing medium isolation valves 6#, 7#, and 8# are located, a booster pump 11 is set upstream of the valve body, and the cleaning medium pressure in the pipeline after the pump is adjusted by the start / stop / frequency control of the booster pump 11.

[0138] (2) A cleaning liquid buffer tank is added, and the tank body is equipped with a liquid level monitoring unit 3, which can automatically control the liquid level through the opening and closing actions of the liquid inlet control valve group 12 (12#, 13#, 14#, 15#, 16#, 17#) and the liquid outlet control valve group 13 (9#, 10#, 11#); at the same time, a high-pressure gas pipeline and a control valve are configured, and the control valve is interlocked with the pressure detection unit of the corresponding buffer tank to automatically control the pressure to the set range.

[0139] It should be emphasized that method (1) and method (2) can be run independently or in combination.

[0140] In addition, the embodiment of the present invention further includes: an HMI interactive interface 9 that interacts with the controller and is configured for parameter input and dynamic configuration, control mode switching, operating status visualization, and triggering and executing manual operation instructions.

[0141] Specifically, in terms of dynamic parameter configuration and priority management, the following functions can be achieved: The operator can preset the flushing medium priority sequence (e.g., disinfectant > purified water > tap water) on the HMI interface, and can also dynamically set the flushing cycle, suction level threshold (liquid level exceeding limit trigger point), and vacuum pressure tolerance range;

[0142] In terms of control mode switching and status visualization, a mode switching panel is provided on the HMI interface, which supports one-touch switching among liquid level trigger mode, timing working mode and manual intervention mode, and displays the current mode status in real time; operating status visualization includes: real-time liquid level curve, vacuum pressure dynamic waveform, medium storage percentage, current flushing medium type and accumulated energy consumption data.

[0143] In terms of manual operation instruction execution, emergency cleaning or temporary debugging operations are triggered through the HMI interface or physical buttons. Double safety confirmation is required when triggered. In manual intervention mode, temporary overwriting of preset parameters is allowed, and operation records are automatically stored in the log and synchronized to the cloud.

[0144] This embodiment achieves deep coupling of control logic and user operations through the HMI interactive interface 9, constructs a high-availability human-machine collaborative control system, and meets the stringent requirements of multiple fields for cleaning processes.
