Description

Technical Field

[0001] This invention relates to the field of dust control technology, specifically to a fully automatic vehicle-mounted dust suppressant preparation and adaptive spraying system and method. Background Technology

[0002] Traditional dust suppression operations mainly rely on water trucks. Existing technologies have significant shortcomings in three aspects: efficient formulation of dust suppressants, maintenance of solution stability, and intelligent spray control. These issues urgently need to be addressed through innovative technologies.

[0003] In dust suppressant formulation, existing methods are generally inefficient and difficult to adapt to high-viscosity materials. Current formulation methods mainly fall into two categories: off-site pre-mixing and simple on-vehicle mixing. Off-site pre-mixing is cumbersome, increasing logistics and time costs; while simple on-vehicle mixing struggles to handle high-molecular polymers (such as polyacrylamide and sodium carboxymethyl cellulose). While there have been attempts at on-vehicle mixing devices, such as the powder-liquid mixing equipment disclosed in Chinese patent CN102658049A mounted on a spray truck chassis, which uses high- and low-speed mechanical agitators to mix powder and water, these technologies rely heavily on traditional mechanical blade agitation. For high-viscosity, poorly soluble polymers, the limited on-vehicle space and time easily lead to the formation of agglomerates that encapsulate the dry powder, resulting in wasted active ingredients and even pipe blockage. Furthermore, the complex mechanical transmission structure increases maintenance costs and failure rates.

[0004] Solution stability is another significant drawback. Dust suppressant solutions (especially complex solutions) are prone to stratification or sedimentation when left to stand. If an operation is not completed, the residual solution often becomes ineffective due to sedimentation before the next use. Existing vehicle-mounted storage tanks are mostly designed for static storage, lacking active dynamic anti-settling mechanisms. Although some industrial mixing plants have adopted circulating anti-settling technology, it has not been effectively integrated into mobile sprinkler trucks, resulting in continuous uneven concentrations before and after dust suppression operations, limiting the stable effectiveness of the dust suppressant.

[0005] The extensive nature of spraying methods further amplifies the shortcomings of traditional technologies. Traditional operations rely heavily on driver experience and cannot precisely adjust based on environmental parameters. Although some intelligent attempts have emerged in the market, such as the automatic spraying device proposed by Chinese patent CN208711305U that uses a dust concentration sensor to control the opening of a high-pressure pump and valves, such existing technologies typically only achieve "threshold-based on-off control" or simple pressure regulation, lacking the ability to dynamically adjust the key variable of dust suppressant solution concentration. In other words, existing technologies fail to achieve a closed-loop control across the entire chain of environmental perception, real-time preparation, concentration adjustment, and precise spraying. They cannot rapidly increase the agent concentration during dust storms, nor can they reduce the concentration in low-dust environments to save costs. Summary of the Invention

[0006] The purpose of this invention is to provide a fully automated preparation and adaptive spraying system and method for vehicle-mounted dust suppressants. By integrating three major modules—automatic preparation, anti-sedimentation circulation, and environmental sensing control—it utilizes a Venturi jet for negative pressure material suction, an online high-shear emulsifying pump to break up agglomerates, and a tubular static mixer to achieve gentle dissolution. Furthermore, it employs an in-tank jet stirring network to create a three-dimensional vortex to prevent sedimentation. Finally, the main control PLC unit dynamically adjusts the spray concentration and flow rate based on real-time environmental data. This effectively solves the technical problems of traditional dust suppression operations, such as high manual feeding intensity, easy agglomeration and uneven dissolution of polymer materials, sedimentation and ineffectiveness of the spray solution, and lack of environmental feedback during the spraying process. It achieves convenient ground feeding, rapid dissolution within minutes, long-lasting uniform and stable spraying, and precise spraying as needed. While significantly improving dust suppression efficiency, it greatly reduces the consumption of agents and water resources, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A fully automatic dust suppressant preparation and adaptive spraying system for vehicles includes a carrier vehicle chassis, on which a clean water tank, a liquid storage tank, a power pump unit, and an automated pipeline system are installed; the system also integrates an automatic preparation module, an anti-sedimentation circulation module, and an environmental perception and adaptive control module.

[0009] The automatic preparation module includes a low-level receiving hopper, a Venturi jet injector, an online high-shear emulsifying pump, and a tubular static mixer connected in sequence, which are used to realize the negative pressure suction, shearing, crushing and dissolution of the dust suppressant;

[0010] The anti-sedimentation circulation module includes a jet stirring network pipe installed at the bottom of the inside of the liquid storage tank and a circulation pump connected thereto, for forming a vortex inside the tank.

[0011] The environmental perception and adaptive control module includes a main control PLC unit, an environmental monitoring sensor group, and a variable frequency metering pump. The main control PLC unit coordinates and adjusts the operating parameters of the power pump group and the variable frequency metering pump based on the data collected by the environmental monitoring sensor group, which is used to perform dual adaptive control of the spraying flow rate and the concentration of the pesticide preparation.

[0012] Preferably, the main inlet of the Venturi jet is connected to the high-pressure outlet of the power pump unit, and its suction inlet is connected to the low-level receiving hopper through a suction hose.

[0013] The Venturi jet injector is equipped with a constriction section, a throat, a diffusion section, and an annular wetting chamber located behind the throat, which is used to pre-wet the inhaled material.

[0014] The online high-shear emulsifying pump is located downstream of the Venturi jet and has at least one shearing unit consisting of a high-speed rotor and a fixed stator. The rotor speed is optimized to be 2000~2800 r / min.

[0015] The tubular static mixer is connected in series downstream of the high-shear emulsifying pump. Its interior consists of a mixing channel formed by staggered spiral blades, providing a dissolution time of 30-60 seconds.

[0016] Preferably, the jet stirring network consists of a central main pipe and multiple branch pipes, with multiple jet nozzles on each branch pipe for forming a vortex in the liquid storage tank.

[0017] The circulating pump is connected to a level switch signal installed on the side wall of the storage tank; the circulating pump is configured to operate in a pulse intermittent mode, stopping for 5 minutes after every 30 seconds of operation.

[0018] Preferably, the environmental monitoring sensor group is installed at the front of the vehicle and includes a laser dust sensor, an anemometer, and a temperature and humidity sensor; the main control PLC unit integrates an expert algorithm module and a PID control module, which are used to calculate the target drug concentration value based on environmental data and adjust the variable frequency metering pump and power pump group in real time through the PID algorithm; the automated pipeline system is also equipped with an online concentration monitor and a flow meter for feedback of system status.

[0019] A fully automated method for preparing and adaptively spraying vehicle-mounted dust suppressants, based on a fully automated system for preparing and adaptively spraying vehicle-mounted dust suppressants, includes the following steps:

[0020] Step 1, Automatic Preparation: The dust suppressant raw material is drawn into the low-level receiving hopper by the high-speed fluid vacuum negative pressure generated by the power pump set through the Venturi jet injector, and flows through the online high-shear emulsifying pump for shearing and crushing and the tubular static mixer for gentle dissolution.

[0021] Step 2, Preventing sedimentation: A swirling flow is formed in the storage tank by a circulating pump and a jet stirring network to maintain uniform suspension of the drug solution in a pulse intermittent mode;

[0022] Step 3, Adaptive Spraying: Environmental data is collected in real time by an environmental monitoring sensor group, and the main control PLC unit dynamically controls the spraying concentration and flow rate based on the expert algorithm module and PID adjustment module.

[0023] Preferably, in the automatic preparation step, the annular wetting chamber of the Venturi jet pre-wets the sucked dry powder; the rotor speed of the online high-shear emulsification pump is maintained at 2000~2800 r / min to reduce the molecular chain shear degradation rate; the tubular static mixer provides a residence time of 30~60s through the helical blades to ensure that the solubility of the dust suppressant reaches more than 99.5%.

[0024] Preferably, in the anti-sedimentation maintenance step, the circulating pump operates in an intermittent mode under the monitoring of the liquid level switch, stopping for 5 minutes after every 30 seconds of operation, in order to reduce energy consumption and reduce foam generation.

[0025] Preferably, in the adaptive spraying step, the expert algorithm module calculates the target pesticide concentration value based on the data fed back by the laser dust sensor and the anemometer; the PID adjustment module compares the target concentration with the actual concentration fed back by the online concentration monitor, generates a correction signal through the PID algorithm, and dynamically adjusts the pesticide addition ratio of the variable frequency metering pump and the spraying flow rate of the power pump group to achieve closed-loop coordinated control of the entire system.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention employs a technical approach combining Venturi negative pressure suction and online high-shear emulsification. The vacuum negative pressure generated by the Venturi jet pump directly draws powder from a low-level receiving hopper on the ground, completely replacing the traditional method of high-altitude feeding that required operators to climb to the roof of the vehicle. This not only significantly reduces labor intensity and safety hazards but also prevents dust dispersion during the feeding process, improving the working environment. The sucked-in material then enters the online high-shear emulsification pump. Its unique multi-stage stator-rotor structure operates within an optimized speed range, efficiently pulverizing insoluble polymer agglomerates while effectively suppressing excessive shear damage to the polymer molecular chains. This achieves a high solubility rate in a short time, fundamentally eliminating the risk of nozzle clogging.

[0028] 2. In this invention, the pulse-intermittent operation mode of the jet nozzle combined with the circulating pump can create a swirling flow within the storage tank, ensuring that the dust suppressant components remain uniformly suspended whether the vehicle is in motion or under prolonged static conditions. This effectively solves the problem of uneven efficacy caused by sedimentation and stratification of the drug solution. Simultaneously, compared to continuous stirring, the intermittent operation mode significantly reduces energy consumption and unnecessary foam generation, improving the system's economy and reliability.

[0029] 3. This invention integrates data from multiple environmental sensors, including those for laser dust, wind speed, temperature, and humidity, and processes this data in real time using expert algorithms and PID control modules within the main control PLC unit. This enables millisecond-level dynamic and coordinated control of the concentration and flow rate of the dust suppressant spraying, forming a complete "perception-decision-execution" closed loop. This allows the system to intelligently respond to changes in the external environment, automatically increasing the agent concentration to enhance the dust suppression effect when dust concentration is high, and optimizing spraying parameters to save resources under low dust or high wind conditions. Through this intelligent on-demand spraying mode, dust suppression efficiency is ensured while minimizing the consumption of agents and water, significantly improving the economic benefits and environmental friendliness of the operation.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] To address the problems of traditional dust suppression operations, such as high manual feeding intensity, easy agglomeration and uneven dissolution of polymer materials, ineffective sedimentation of the pesticide solution, and lack of environmental feedback during spraying, please refer to [link to relevant documentation]. Figure 1-3 This embodiment provides the following technical solution:

[0036] like Figure 1 As shown, the present invention is integrated on the chassis 100 of the carrier vehicle, and the system logic covers three major loops: fluid preparation, dynamic anti-sinking and intelligent control.

[0037] In the preparation process, the power pump unit 400 drives clean water to be drawn into the raw material in the low-level receiving hopper 501 through the negative pressure of the Venturi jet injector 502. The liquid then flows sequentially through the online high-shear emulsifying pump 503 and the tubular static mixer 505 to complete multi-stage dispersion and dissolution before entering the storage tank 300. During storage, the anti-sedimentation circulation pump 601 and the jet stirring network 602 in the storage tank 300 continuously form a closed-loop fluid circulation to maintain the homogeneity and stability of the liquid. In terms of operation control, the main control PLC unit 702 controls the process through... Figure 1 The electrical network shown by the dashed line collects feedback data from the environmental monitoring sensor group 701, the laser dust sensor 701a, and the temperature and humidity sensor 701c, and coordinates the operation parameters of the variable frequency metering pump 801 and the front-end pump group, ultimately driving the fog cannon equipment 901 to achieve adaptive and precise spraying based on environmental perception.

[0038] like Figure 2 As shown, the automatic mixing module 500 mainly consists of a low-level receiving hopper 501, a Venturi jet injector 502, an online high-shear emulsifying pump 503, and a tubular static mixer 505 in terms of hardware implementation of the automatic mixing function. The low-level receiving hopper 501 is located on the side of the vehicle, with its feeding port height designed within an ergonomic range of 1.0 to 1.2 meters above the ground, facilitating ground-level feeding by operators. A high-frequency vibrator 506 is installed on the conical neck of the low-level receiving hopper 501, with a vibration frequency of 50-100Hz and an amplitude of 0.5-2mm, effectively breaking up bridging phenomena in polymer powders. The bottom of the low-level receiving hopper 501 is connected to the suction port of the Venturi jet injector 502 via a suction hose 504. This suction hose 504 is preferably made of reinforced transparent steel wire hose, which can prevent flattening due to negative pressure and allows for direct monitoring of material flow. A one-way check valve 507 is also installed on the pipeline to prevent backflow of liquid when the machine stops.

[0039] The Venturi jet injector 502 is installed on the high-pressure outlet bypass of the power pump unit 400. Its structure includes a contraction section 502a, a throat 502b, and a diffusion section 502c. An annular wetting chamber 502d is located after the throat 502b, where a water film is formed by micro-orifice jetting to pre-wet the absorbed dry powder, preventing the formation of dry agglomerates. An online high-shear emulsifying pump 503 is connected in series downstream of the Venturi jet injector 502. It integrates a three-stage stator-rotor shearing unit 503a, with a rotational speed set between 2000 and 2800 rpm, a 20%-30% reduction compared to traditional speeds. This ensures effective dispersion while controlling the molecular chain shear degradation rate to within 5%. Subsequently, the pre-dispersed solution enters the tubular static mixer 505, where the internal helical blades 505a provide a residence time of approximately 45 seconds, allowing polymer molecules to fully expand and dissolve in a mild environment, ultimately achieving a solubility of over 99.5%.

[0040] To address the sedimentation issue of dust suppressants during storage and transportation, an anti-sedimentation circulation module is installed at the bottom of the storage tank 300. This module consists of a circulation pump 601 and a jet-stirring network pipe 602. The jet-stirring network pipe 602 employs a central main pipe arranged longitudinally along the tank body and symmetrically arranged branch pipes on both sides. Several jet nozzles are installed at equal intervals in a matrix on each branch pipe, creating a forced swirling flow within the tank through jet scouring. A level switch is installed on the side wall of the storage tank 300. When the liquid level is 30cm below the nozzle, the circulation pump 601 is automatically shut off to prevent air entrainment. The circulation pump 601 operates in a pulse intermittent mode: it operates for 30 seconds and then stops for 5 minutes, reducing energy consumption by more than 40% while maintaining the suspension effect and significantly reducing foam generation.

[0041] like Figure 3 As shown, in terms of intelligent operation and control, the system is equipped with an environmental perception and control module 700. This module, with the main control PLC unit 702 as its core, constructs a closed-loop control loop of "perception-decision-execution". At the perception level, the system integrates a multi-dimensional sensor group, including an environmental monitoring sensor group 701, a system status sensor, a liquid level sensor 703b, and a flow meter 703c.

[0042] Specifically, the environmental monitoring sensor group 701 is installed at the front of the vehicle and includes a laser dust sensor 701a, an anemometer 701b, and a temperature and humidity sensor 701c, used to collect external working environment data in real time; the system status sensors include an online concentration monitor 703a installed on the liquid outlet pipeline, used to provide feedback on the actual concentration of the liquid; the liquid level sensor 703b is installed inside the storage tank, used to monitor the remaining amount of liquid to prevent the pump from running dry; and the flow meter 703c is installed on the main pipeline, used to accurately measure the instantaneous flow rate and cumulative workload.

[0043] At the decision-making and execution level, the main control PLC unit 702 integrates an expert algorithm module and a PID control module to coordinate the control of the variable frequency metering pump driver 801, the power pump group frequency converter 401, the circulating pump contactor 601a, and the automated pipeline system 900.

[0044] The specific adaptive adjustment logic is as follows: During operation, the expert algorithm module first makes macro-level decisions based on data fed back from the environmental monitoring sensor group 701: when the anemometer 701b detects strong winds, it coordinates the adjustment of the pressure or angle of the fog cannon 901; when the laser dust sensor 701a detects an increase in dust concentration, the algorithm calculates the target pesticide concentration value required for the current working condition. Subsequently, the PID adjustment module intervenes in the precise control stage, comparing the target pesticide concentration value with the actual concentration value fed back by the online concentration monitor 703a in real time and calculating the deviation. Using the proportional-integral-derivative algorithm, i.e., the PID algorithm, the corrected frequency signal is automatically calculated and sent to the variable frequency metering pump driver 801 to fine-tune the pesticide injection amount at the millisecond level. At the same time, the main control PLC unit 702 adjusts the frequency of the power pump group based on data fed back from the flow meter 703c, and automatically cuts off the circulation pump contactor 601a to protect the equipment when the liquid level is low based on the signal from the liquid level sensor 703b. This multi-parameter coupled closed-loop mechanism realizes precise and safe dust suppression based on environmental feedback.

[0045] Working principle: Based on the carrier vehicle chassis 100 as the basic platform, when the automatic preparation module 500 starts, the power pump unit 400 drives the clean water to flow through the Venturi jet injector 502. The vacuum negative pressure is generated by the structure of its contraction section 502a, throat 502b and diffusion section 502c. The dust suppressant raw material is sucked in from the low-level receiving hopper 501 through the suction hose 504. After the raw material is pre-wetted in the annular wetting chamber 502d, it enters the online high-shear emulsification pump 503. Its three-stage stator and rotor shearing unit 503a crushes the agglomerates at a speed of 2000~2800r / min. Then, the spiral blades 505a inside the tubular static mixer 505 provide extended time to achieve complete dissolution. Finally, the liquid is discharged into the storage tank 300.

[0046] During the storage phase, the anti-sedimentation circulation module ensures the stability of the liquid medicine. The circulation pump 601 draws the liquid medicine from the bottom of the tank and delivers it through the central main pipe and branch pipes of the jet stirring network 602, which is then sprayed out by the jet nozzle to form a three-dimensional vortex. The liquid level switch monitors the liquid level, and the circulation pump 601 operates in a pulse intermittent mode to prevent sedimentation and reduce energy consumption.

[0047] During spraying, the environmental sensing and control module 700 achieves intelligent adjustment. The laser dust sensor 701a, anemometer 701b, and temperature and humidity sensor 701c of the environmental monitoring sensor group 701 collect data in real time. The main control PLC unit 702 calculates the target concentration using expert algorithms and compares it with feedback values ​​from system status sensors 703 such as the online concentration monitor 703a and flow meter 703c. Using PID control to regulate the variable frequency metering pump driver 801 and the power pump group frequency converter 401, the system dynamically adjusts the pesticide ratio and spray flow rate. Finally, the automated pipeline system 900 and the fog cannon equipment 901 complete the adaptive operation. The entire system forms a closed-loop control, improving dust suppression efficiency and resource utilization.
