Description

Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, and in particular to an intelligent potassium permanganate disinfection vehicle. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] With increasingly stringent public health and safety requirements, particularly in water treatment, medical facilities, and disinfection of epidemic areas, the demand for efficient, precise, and safe mobile disinfection equipment is becoming increasingly urgent. Potassium permanganate, as a powerful oxidizing disinfectant, is widely used in such scenarios. However, existing disinfection equipment, including stationary disinfection devices and traditional mobile disinfection vehicles, still faces significant technical bottlenecks in addressing the disinfection needs of dynamic environments.

[0004] In the existing technology, disinfection vehicles mainly have the following technical problems:

[0005] (1) Unable to move or limited coverage: Fixed disinfection equipment (such as ultraviolet disinfection machine and fixed sodium hypochlorite dosing system) cannot be moved and there are disinfection dead spots; even some mobile equipment has limited mobility and path planning capabilities, making it difficult to achieve seamless full coverage disinfection in complex environments.

[0006] (2) Low precision in disinfection concentration control: The disinfection effect of potassium permanganate is highly dependent on the precise control of solution concentration. Existing mobile disinfection equipment mostly relies on manual experience for mixing and dosing, or adopts simple open-loop control, which makes it difficult to monitor and dynamically adjust the concentration of the flowing solution in the pipeline in real time, resulting in large concentration fluctuations, unstable disinfection effect, and easy waste of reagents or incomplete disinfection.

[0007] (3) High safety risks: Potassium permanganate solution is highly corrosive. Traditional storage tanks have simple sealing structures, which are prone to leakage due to seal failure or loose tank connections, especially in the vibration environment of mobile equipment, endangering equipment, environment and operator safety. The installation and fixing methods of key components (such as pumps and valves) on mobile equipment (such as simple binding or non-rigid connections) are unreliable. Vibration during equipment movement or operation can easily lead to loose connections, component displacement, increased pipeline stress or even rupture and leakage, while also affecting the working accuracy and lifespan of components (such as metering pumps). There is a lack of real-time perception of the working environment (such as obstacles, personnel approach), and it is impossible to actively avoid obstacles or suspend operations in an emergency during movement, which poses risks of equipment collision, accidental personnel contact with disinfectant or incomplete disinfection.

[0008] (4) Pipeline pressure fluctuations affect spraying effect: When mobile disinfection equipment is started, stopped, or moved and bumped, the pipeline pressure is prone to fluctuation, which leads to unstable atomization effect of the nozzle and uneven spraying, thus affecting the disinfection effect. Existing equipment lacks effective pressure stabilization measures. Utility Model Content

[0009] To address the shortcomings of existing technologies, this invention proposes an intelligent potassium permanganate disinfection vehicle, which is equipped with a liquid storage unit, a liquid dispensing and delivery unit, a spraying unit, and an environmental sensing system. It has the advantages of improving disinfection efficiency, ensuring stable disinfection solution concentration, and enhancing equipment mobility and safety.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A smart potassium permanganate disinfection vehicle includes:

[0012] Mobile vehicle body;

[0013] The disinfection system is fixedly installed on the mobile vehicle body and includes a liquid storage unit, a liquid preparation and delivery unit, and a spraying unit; the liquid storage unit, the liquid preparation and delivery unit, and the spraying unit are connected in sequence through a solution circulation pipeline;

[0014] The control system is fixedly installed on the mobile vehicle body and includes a controller and an environmental sensing unit;

[0015] The solution delivery unit includes a concentration detection element and a flow regulation element;

[0016] The controller is connected to the concentration detection element and the flow regulation element.

[0017] Furthermore, the disinfection system also includes:

[0018] A back pressure valve assembly is installed on the spray pipe of the spraying unit;

[0019] A metering pump assembly is installed on the solution circulation pipeline.

[0020] Furthermore, the liquid storage unit includes: a corrosion-resistant liquid storage tank and a liquid level detection element; the liquid level detection element is disposed inside the liquid storage tank.

[0021] Furthermore, the opening of the liquid storage tank is equipped with a double-layer sealing cap.

[0022] Furthermore, the solution dispensing and delivery unit also includes a power pump, which is installed on the solution circulation pipeline.

[0023] Furthermore, the spraying unit includes: a spraying pipeline, a nozzle, and an on / off valve;

[0024] The nozzle is located at the end of the spraying pipeline; the on / off valve is located on the spraying pipeline;

[0025] The on / off valve is connected to the controller.

[0026] Furthermore, the environmental perception unit includes: an obstacle detection sensor and a human body sensing sensor;

[0027] Both the obstacle detection sensor and the human body sensing sensor are connected to the controller.

[0028] Furthermore, the mobile vehicle body includes a frame and wheels, with the wheels mounted on the bottom of the frame.

[0029] Furthermore, the back pressure valve assembly includes a back pressure valve body (1-16), a pulse damper (1-8), a first pipe (1-3), and a PVC plate mounting plate (1-14); the back pressure valve body (1-16) and the pulse damper (1-8) are fixed to the PVC plate mounting plate (1-14) by fasteners.

[0030] Furthermore, the metering pump assembly includes an electromagnetic diaphragm metering pump (2-1), a one-way valve pump component (2-3), a hose (2-2), a second pipe (2-6), and a plate mounting plate (2-10); the electromagnetic diaphragm metering pump is fixed to the plate mounting plate (2-10) by screws (2-11).

[0031] Compared with the prior art, the intelligent potassium permanganate disinfection vehicle provided by this utility model has the following beneficial effects:

[0032] (1) By adopting a mobile vehicle with wheels and integrating an environmental perception unit (obstacle detection, human body sensing sensor) and control system, this disinfection vehicle can move autonomously or along a preset path in a dynamic environment to achieve full coverage disinfection without dead angles. It is especially suitable for places with complex spaces and frequent personnel flow.

[0033] (2) A closed-loop control system consisting of a concentration detection element (located on the solution circulation pipeline), a flow regulation element (such as a metering pump assembly), and a controller is adopted. The controller receives the concentration signal in real time and dynamically adjusts the flow regulation element (such as the stroke / frequency of the metering pump) to ensure that the concentration of the disinfectant solution is accurate and stable (e.g., error ≤ ±5%), significantly reducing human operation errors and reagent waste.

[0034] (3) Set up solution circulation pipelines and power pumps to ensure continuous circulation of disinfectant solution, avoid precipitation and concentration stratification, and ensure the representativeness of concentration detection and the uniformity of spray concentration.

[0035] (4) The liquid storage unit adopts a corrosion-resistant liquid storage tank (such as PTFE-coated stainless steel / fiberglass) and a double-layer sealing cover (inner elastic sealing ring + outer threaded cover), which significantly reduces the risk of leakage of highly corrosive solutions under static and dynamic (vibration) conditions.

[0036] (5) The back pressure valve assembly is securely fixed to the PVC plate mounting plate (1-14) using fasteners such as U-clamps (1-13) and screws (1-15, 1-18). The metering pump assembly is securely fixed to the plate mounting plate (2-10) using screws (2-11). The above-mentioned modular and rigid installation method greatly enhances the structural stability and connection reliability of the back pressure valve and metering pump in mobile and vibration environments, effectively preventing loosening, displacement, leakage and component damage caused by vibration.

[0037] (6) The environmental perception unit (obstacle detection + human body sensing sensor) is linked with the controller. When an obstacle is detected, the path is adjusted to avoid the obstacle; when a person is detected approaching, spraying is immediately paused and the speed is reduced, and it is resumed after the person leaves, effectively ensuring the safety of the personnel and avoiding accidental spraying of pesticides.

[0038] (7) A back pressure valve assembly is installed in the disinfection system. The core back pressure valve (1-16) maintains the set pressure through spring preload. When the spraying starts or stops or the flow rate changes, causing fluctuations in pipeline pressure, the back pressure valve can automatically adjust its opening to stabilize the pipeline pressure, thereby ensuring the stability of the nozzle atomization effect and the uniformity of spraying. The back pressure valve also works in conjunction with the pulse damper (1-8) to further absorb pipeline pressure. Attached Figure Description

Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0048] Example 1

[0049] like Figures 1 to 4 A smart potassium permanganate disinfection vehicle, comprising: a mobile vehicle body;

[0050] The disinfection system is fixedly installed on the mobile vehicle body and includes a liquid storage unit, a liquid preparation and delivery unit, and a spraying unit; the liquid storage unit, the liquid preparation and delivery unit, and the spraying unit are connected in sequence through a solution circulation pipeline;

[0051] The control system is fixedly installed on the mobile vehicle body and includes a controller and an environmental sensing unit;

[0052] The solution delivery unit includes a concentration detection element and a flow regulation element;

[0053] The controller is connected to the concentration detection element and the flow regulation element.

[0054] The mobile vehicle body refers to the basic platform carrying the disinfection and control systems. It can be implemented using a frame structure with wheels, providing mobility to expand the disinfection coverage area. The storage unit is the container for storing potassium permanganate solution, typically a sealed tank made of corrosion-resistant material, preventing leakage and ensuring storage stability. The solution mixing and delivery unit is the component that mixes the solution and adjusts delivery parameters, typically a module with circulation piping and a power pump, dynamically adjusting solution concentration and flow rate. The spraying unit is the terminal component that performs disinfectant atomization spraying, typically using a piping structure with adjustable nozzles and on / off valves, precisely controlling the disinfectant coverage area. The environmental sensing unit is a sensor array that collects environmental data, typically using infrared or ultrasonic sensors, identifying obstacles and personnel locations to adjust the work path. The concentration detection element is a device that monitors solution concentration in real time, typically using conductivity or optical sensors, feeding back concentration data to the controller to trigger flow rate adjustments. Flow regulating elements are actuators that control the flow rate of a solution. They can be implemented using solenoid valves or metering pumps, and their function is to adjust the pipeline flow rate according to control commands.

[0055] Specifically, the mobile vehicle moves autonomously within the work area using its wheels, eliminating blind spots covered by fixed equipment. The potassium permanganate solution stored in the storage unit is circulated and mixed by the dispensing and delivery unit. The concentration is monitored in real-time by a concentration detection element. When the concentration deviates from the preset value, the controller sends a command to the flow regulation element to restore the target concentration by adjusting the addition ratio of clean water or concentrate. The spraying unit controls the opening and closing of the on / off valves based on obstacle distribution information fed back by the environmental sensing unit, avoiding obstacle areas during movement. When the environmental sensing unit detects personnel approaching, the controller pauses spraying to avoid contact risk, resuming operation after the personnel have left.

[0056] Compared to existing technologies, traditional fixed disinfection equipment is limited by its installation location and cannot provide full coverage of dynamic environments. This solution, however, achieves free spatial movement through a mobile vehicle. Manual operation requires frequent adjustments to concentration parameters, while this solution achieves automated solution dispensing through closed-loop control of concentration detection and flow regulation. Traditional storage tanks are prone to leakage due to insufficient sealing, while this solution improves safety through a corrosion-resistant and airtight structure. Existing equipment lacks environmental awareness capabilities, while this solution uses a sensor array to achieve dynamic planning of the work path and personnel avoidance.

[0057] Through the above technical solutions, this application achieves full-area coverage of disinfection operations in dynamic environments. Closed-loop control ensures solution concentration stability and reduces human error. The sealed liquid storage structure effectively reduces leakage risk, and the environmental sensing module enhances the safety of the operation process, avoiding the risks of equipment collisions and personnel contact.

[0058] Specifically, the liquid storage unit includes a corrosion-resistant liquid storage tank and a liquid level detection element; the liquid level detection element is disposed inside the liquid storage tank. Specifically, the liquid storage tank has a leak-proof structure, which is a double-layer sealing cap disposed at the opening of the liquid storage tank.

[0059] Corrosion-resistant storage tanks are containers made of chemically resistant materials, such as PTFE-coated stainless steel or fiberglass. An anti-corrosion protective layer forms on the inner wall surface, preventing direct contact between the potassium permanganate solution and the tank body from causing corrosion. This structure ensures the tank remains completely sealed during long-term storage of potassium permanganate solution.

[0060] The liquid level detection element refers to a sensor device used to measure the height of the solution inside the tank. Specifically, it can be implemented using a capacitive liquid level sensor or an ultrasonic liquid level sensor. The sensor probe is vertically mounted on the inner wall of the storage tank, and real-time liquid level data is calculated by detecting the difference in dielectric constant between the solution and air or the time difference of sound wave reflection. This element establishes a data connection channel with the control system to transmit monitoring signals.

[0061] Through the above technical solution, this application effectively prevents the risk of leakage of potassium permanganate solution caused by corrosion of the storage tank, ensures the stability of disinfectant solution supply through real-time liquid level monitoring, and avoids equipment shutdown or disinfectant dosage deviation due to abnormal liquid level.

[0062] Specifically, the solution preparation and delivery unit further includes a power pump, which is installed on the solution circulation pipeline.

[0063] Leak-proof structures refer to physical devices used to prevent liquid from leaking out of the storage tank. Specifically, this can be achieved by installing two independent sealing layers at the tank opening, such as an inner elastic sealing ring and an outer threaded cap. A double-layer sealing cap refers to a closed structure composed of two independent sealing components. Specifically, it can be a combination of an inner sealing ring and an outer cap. The inner sealing ring fills the gap through elastic deformation, while the outer cap applies pressure through threaded locking, forming a double barrier layer.

[0064] Specifically, the opening of the storage tank, as the critical point of contact between the solution and the outside environment, achieves redundant protection through a double-layered sealing interface. When the storage tank is moved or vibrated, if the inner sealing ring develops tiny gaps due to material aging or mechanical stress, the outer gland can still maintain the sealing pressure through threaded locking, preventing solution leakage. The two sealing structures perform the main sealing and auxiliary sealing functions respectively under static and dynamic conditions. For example, during bumpy transportation, the rigid structure of the outer gland can withstand external impacts, while the elastic material of the inner sealing ring can absorb vibration energy.

[0065] Through the above technical solution, this application effectively reduces the risk of leakage of highly corrosive solutions at the opening of the storage tank, avoids damage to equipment and the environment caused by solution evaporation or leakage, and reduces the frequency of maintenance due to seal failure. The synergistic effect of the two-layer sealing structure enables the storage tank to maintain a stable sealing state even in dynamic movement scenarios, solving the problem of easy failure of traditional single-layer seals in areas of mechanical stress concentration.

[0066] Specifically, the spraying unit includes: spraying pipeline, nozzle, and on / off valve;

[0067] The nozzle is located at the end of the spraying pipeline; the on / off valve is located on the spraying pipeline;

[0068] The on / off valve is connected to the controller.

[0069] The solution circulation pipeline refers to a closed channel that enables the disinfectant solution to circulate between the storage unit and the spraying unit. It can be implemented using corrosion-resistant PTFE tubing or 316L stainless steel tubing. Its loop design prevents concentration stratification caused by solution stagnation during transport. The power pump is the device that provides the power required for the flow of the disinfectant solution. It can be implemented using a magnetically driven centrifugal pump or a diaphragm pump. Adjusting the pump speed allows for precise control of the solution flow rate, thereby maintaining a stable flow velocity within the pipeline. The concentration detection element is a sensor that monitors the potassium permanganate content in the flowing solution in real time. It can be implemented using a conductivity sensor or an online ultraviolet spectrometer. Directly installed in the circulation pipeline, it captures real-time concentration data under dynamic flow conditions.

[0070] Specifically, the disinfectant solution forms a closed-loop flow path through a solution circulation pipeline, continuously circulating under the drive of a power pump. During the flow, a concentration detection element collects solution concentration data in real time and feeds it back to the controller. The controller dynamically adjusts the output power of the power pump according to a preset concentration threshold. When the detected concentration is lower than the set value, the controller increases the power pump speed to increase the solution circulation volume per unit time, promoting the replenishment of high-concentration solution in the storage unit; when the detected concentration is too high, the controller reduces the pump speed to reduce the solution circulation volume, and simultaneously triggers the dispensing unit to replenish diluent. This dynamic adjustment mechanism can eliminate local concentration differences caused by solution settling, and at the same time avoids the flow fluctuation problem of traditional gravity delivery methods by maintaining a stable flow rate.

[0071] Through the above technical solutions, this application can maintain the uniformity of concentration during the delivery of disinfectant solutions, avoiding local over-concentration or dilution. Simultaneously, it ensures the stability of solution supply under different spraying conditions by actively adjusting the circulation flow rate. Based on the structural design of the circulation pipeline, it effectively eliminates the problem of solid particle sedimentation caused by solution settling in traditional equipment, extending the service life of the pipeline. Compared with manual sampling detection methods, the real-time online concentration detection mechanism significantly improves the accuracy and response speed of concentration control.

[0072] Specifically, the environmental perception unit includes: an obstacle detection sensor and a human body sensing sensor;

[0073] Both the obstacle detection sensor and the human body sensing sensor are connected to the controller.

[0074] Specifically, the mobile vehicle body includes a frame and wheels, with the wheels mounted on the bottom of the frame.

[0075] Specifically, the disinfection system also includes a back pressure valve assembly and a metering pump assembly.

[0076] Among them, such as Figure 5 The back pressure valve assembly is installed on the spraying pipeline of the spraying unit to stabilize the pipeline pressure.

[0077] The core components of the back pressure valve assembly include the back pressure valve body (1-16) and the pulse damper (1-8). Connecting components include: a first tee (1-1), a union (1-2), a first pipe (1-3), an external thread (1-4), a first double-union ball valve (1-5), a first elbow (1-6), a first pipe clamp (1-7), a PE barrel internal thread connector (1-9), a rigid pipe (1-10), an injection valve (1-11), and a first internal thread (1-12). Fixing components include: a U-shaped clamp (1-13), a PVC plate mounting plate (1-14), screws (1-15, 1-18), and a lock (1-17).

[0078] The connection relationships of the above structures are as follows:

[0079] The back pressure valve body and the pulse damper are fixed to the PVC sheet mounting plate (1-14) by U-shaped clips (1-13) and screws (1-15, 1-18) to form a rigid mounting structure.

[0080] The first pipe (1-3) is connected to the first tee (1-1), the first elbow (1-6) and other fittings through the external thread (1-4), the first internal thread (1-12), etc., to form a complete pipeline.

[0081] The first double-controlled ball valve (1-5) is installed on the pipeline to control the flow of fluid; the pulse damper (1-8) is connected in parallel on the pipeline to cooperate with the back pressure valve body to stabilize the pressure.

[0082] The rigid tube (1-10) is connected to the injection valve (1-11) for replenishing the reagent or cleaning the pipeline.

[0083] The back pressure valve body maintains the set pressure in the pipeline through spring preload. When spraying starts or stops, or when flow changes cause pressure fluctuations, it automatically adjusts the opening to maintain constant pressure, ensuring stable atomization from the nozzles. The pulse damper (1-8), in conjunction with the back pressure valve body, absorbs pressure pulses in the pipeline caused by the start and stop of the power pump, reducing fluid fluctuations and improving spray uniformity. The first double-joint ball valve (1-5) can shut off the pipeline during maintenance to prevent solution leakage; its rigid fixed structure prevents loosening of connections due to vibration, improving equipment safety.

[0084] like Figure 6 The metering pump assembly is installed on the solution circulation pipeline as part of the flow regulation element.

[0085] The core components of the metering pump assembly include an electromagnetic diaphragm metering pump (2-1) and a one-way valve pump (2-3). The connecting components include a hose (2-2), a second elbow (2-4), a second double union ball valve (2-5), a second pipe (2-6), a second internal thread (2-7), and a second tee (2-9). The fixing components include stainless steel screws (2-8), a plate mounting plate (2-10), screws (2-11), and a second pipe clamp (2-12).

[0086] The structural connections described above are as follows:

[0087] The electromagnetic diaphragm metering pump (2-1) is fixed to the plate mounting plate (2-10) by screws (2-11), and the one-way valve pump component (2-3) is connected to the metering pump outlet by a pipeline connector.

[0088] The hose (2-2) connects the metering pump inlet to the liquid storage unit or liquid distribution pipeline to adapt to displacement changes under vibration environment.

[0089] The second pipe (2-6) is connected to the second double-ruler ball valve (2-5) through the second internal thread (2-7), the second elbow (2-4), the second tee (2-9), and the second double-ruler ball valve to form a flow control loop.

[0090] One-way valve pump components (2-3) are installed on the outlet pipeline to prevent solution backflow and ensure metering accuracy.

[0091] The electromagnetic diaphragm metering pump uses electromagnetic drive to reciprocate the diaphragm. The controller adjusts the pump's stroke or frequency based on the concentration detection signal to achieve precise control of the disinfectant solution flow rate (error ≤ ±5%), ensuring stable concentration. A one-way valve (2-3) prevents backflow of the solution in the pipeline, avoiding metering deviations caused by pressure fluctuations and ensuring accurate solution delivery. The flexible connection of the hose (2-2) reduces the impact of vibration on the metering pump, and the second double-handled ball valve (2-5) can adjust the branch flow rate to adapt to the needs of different disinfection scenarios.

[0092] Through the above technical solution, this application effectively prevents leakage of highly corrosive solutions caused by shaking of the storage tank or failure of the seal, maintains stable pipeline pressure when the spraying unit is working, achieves precise control of disinfectant solution flow, reduces human operation error, and reduces equipment maintenance frequency.

[0093] The intelligent potassium permanganate disinfection vehicle provided by this utility model achieves dynamic disinfection through three core mechanisms: mobile execution, closed-loop solution preparation, and environmental perception linkage. The specific working principle is as follows:

[0094] 1. Preparation phase: Scan the work environment.

[0095] Once the control system is activated, the environmental perception unit (obstacle detection sensor, human body sensing sensor) scans the work area in real time, generates an environmental map, and marks the location of obstacles.

[0096] The controller plans the movement route based on the preset disinfection path or real-time environmental data and sends drive commands to the wheels of the mobile vehicle.

[0097] 2: During the movement phase, achieve dynamic movement and safe obstacle avoidance.

[0098] The moving vehicle travels along the planned path:

[0099] When the obstacle detection sensor identifies an obstacle (such as equipment or a wall) ahead, the controller immediately adjusts the steering angle of the walking wheels to enable active detour.

[0100] If the human body sensor detects a person approaching within the operating radius (3-5 meters), the controller will simultaneously execute the following: a. Suspend the drive of the walking wheels, and the vehicle will stop moving; b. Close the on / off valve of the spraying unit to stop the spraying of disinfectant; c. Resume movement and spraying operations after the person leaves the detection range.

[0101] 3: Achieving closed-loop solution preparation and precise concentration control based on power pumps and metering pumps.

[0102] Solution circulation start-up: The power pump drives the potassium permanganate solution in the storage unit into the solution circulation pipeline, forming a closed-loop flow;

[0103] Dynamic concentration adjustment:

[0104] a. The concentration detection element monitors the concentration data of the flowing solution in the pipeline in real time and feeds it back to the controller;

[0105] b. When the detected concentration is lower than the preset threshold: the controller increases the stroke frequency of the metering pump assembly to replenish the circulation pipeline with high-concentration stock solution;

[0106] c. When the detected concentration is higher than the preset threshold: the controller reduces the output flow of the metering pump and simultaneously triggers the addition of dilution solvent;

[0107] The metering pump features a dual protection mechanism: • A one-way valve prevents solution backflow, ensuring accurate dosing; • Flexible hose connection absorbs vehicle vibration, preventing metering deviation.

[0108] 4: Achieving pressure stabilization and intelligent spraying based on back pressure valves

[0109] Back pressure valve pressure stabilization operation:

[0110] When the spraying unit starts or stops or the vehicle body is bumped, causing fluctuations in pipeline pressure, the back pressure valve body automatically adjusts the opening through spring preload to maintain a constant pipeline pressure (0.3-0.5MPa).

[0111] The pulse damper works together to absorb the water hammer effect generated by the start-up and shutdown of the power pump, smoothing out pressure pulsations;

[0112] On-demand spraying control:

[0113] The controller controls the on / off valve based on environmental sensing data: • When the path is clear, the on / off valve opens, and the disinfectant is sprayed through the nozzles in an atomized manner; • When an obstacle or person is encountered, the on / off valve closes, and the spraying is interrupted.

[0114] 5: Safety Protection and Status Monitoring

[0115] First, the double-layer sealing cover (inner elastic sealing ring + outer threaded cap) of the liquid storage tank forms a redundant seal under vibration environment; second, the liquid level detection element provides real-time warning of the remaining solution level, and the controller stops the power pump when the liquid level is too low to prevent dry running damage; at the same time, the back pressure valve assembly is rigidly fixed to the PVC mounting plate by U-shaped clips and screws; the metering pump assembly is anchored to the plate mounting plate by screws to suppress component displacement caused by movement vibration.

[0116] In this invention, the controller issues commands based on a pre-set configuration file. The configuration logic of the configuration file is set according to actual needs and is easily implemented by those skilled in the art. The configuration file provided by this invention is stored in the controller's hardware storage unit based on the provided preset rules. This invention does not improve the software algorithm.

[0117] In the description of this specification, the terms "connection", "installation", "fixing", "setting", etc. are interpreted in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and the technical effect. It can also be an integral connection or a partial connection. In such cases, those skilled in the art can understand the specific meaning of the above terms in this utility model or utility model according to the specific circumstances.
