Description

Technical Field

[0001] This invention relates to the field of hygiene management technology for drinking water systems in livestock and poultry farming, and in particular to a method, apparatus, equipment, and storage medium for cleaning drinking water systems for chickens. Background Technology

[0002] Biofilms that continuously grow on the inner walls of drinking water lines are the core source of excessive bacterial contamination in livestock and poultry drinking water. These biofilms, formed by the interweaving of pathogenic bacteria and extracellular polymeric substances (EPS), densely adhere to the inner walls of the pipes. They not only clog the drinking water pipes but also continuously release microorganisms into the water, causing intestinal diseases in livestock and poultry.

[0003] Current mainstream biofilm control solutions have significant shortcomings:

[0004] Chemical cleaning methods, which rely on soaking and rinsing with agents such as hydrogen peroxide, peracetic acid, and acidifiers, are the mainstream solution in the industry. However, this method carries risks of drug residues and bacterial resistance, has high costs for agent procurement and labor, and can only be used infrequently when the pen is empty or at night, making it impossible to achieve continuous daily disease control.

[0005] Flushing method: Existing technologies typically use high-pressure flushing, relying on mechanical shearing force to peel off biofilms. However, this method can only remove loose surface biofilms and has a low peeling rate for mature, dense hydrated biofilms. The industry's conventional improvement approach is to use chemical agents to assist in the disintegration process, which cannot eliminate the dependence on chemicals. Summary of the Invention

[0006] The main objective of this invention is to provide a method, apparatus, equipment, and storage medium for cleaning the drinking water system of chickens. This invention aims to address the problems of existing chemical cleaning methods, such as drug residues, bacterial resistance, high costs of drug procurement and labor, limited use only in empty pens or at night, inability to achieve continuous daily prevention and control, and the fact that rinsing methods can only remove loose surface biofilms with low peeling rates for mature and dense hydrated biofilms. The industry's conventional improvement path involves adding chemical agents to assist in the disintegration of the biofilm, which cannot eliminate the dependence on chemicals.

[0007] In a first aspect, to achieve the above objectives, the present invention provides a method for cleaning a chicken's drinking water system, which is performed periodically during the normal chicken rearing cycle, comprising:

[0008] Drain the water from the drinking water pipes and keep the inside of the pipes in a dry and ventilated state for 2-3 hours to allow the extracellular matrix of the biofilm on the inner wall of the pipes to lose water, shrink and crack, and reduce the interfacial adhesion between the biofilm and the pipe wall.

[0009] Pulsed high-pressure water flow is introduced into the drinking water pipes to peel off the dried and loose biofilm;

[0010] The detached biofilm fragments are discharged from the end of the pipe with the flushing water flow, and then the normal water supply pressure of the pipe is restored, and the pipe enters the daily water supply state.

[0011] Optionally, the evacuation operation is started 3 to 3.5 hours before the preset lighting time of the chicken house the next day, and the pulsed high-pressure water flow operation is performed 20 to 40 minutes before the preset lighting time of the chicken house.

[0012] Optionally, the evacuation operation should not be performed earlier than 20 minutes after the lights in the chicken coop are turned off.

[0013] Optionally, the peak pressure of the pulsed high-pressure water flow is 0.3~0.75MPa, the duration of a single pulse is 1s, the interval between two adjacent pulses is 5s, and a total of 8~12 pulse flushing cycles are performed.

[0014] Optionally, after the pulsed high-pressure water flushing ends, maintain the high-pressure water flow for 30-60 seconds.

[0015] Optionally, before draining the water from the drinking water pipes, pre-flushing the pipes at normal pressure for 30-60 seconds using the daily water supply pressure.

[0016] Optionally, it also includes: starting from the start of the purging operation, when the water supply to the drinking water pipeline is interrupted for 4 hours, restoring the normal water supply to the drinking water pipeline and triggering an alarm.

[0017] Secondly, the present invention also provides a cleaning device for a chicken's drinking water system, comprising:

[0018] The drainage module is used to drain the water stored in the drinking water pipes and maintain the ventilation between the inside of the pipes and the outside air.

[0019] The booster water supply module is used to output an adjustable pressure pulsed high-pressure water flow;

[0020] The control module is electrically connected to the drainage module and the booster water supply module, respectively, and is used to control the automatic execution of the emptying, drying and pulse rinsing processes according to a preset time sequence.

[0021] Thirdly, the present invention also provides a chicken drinking system cleaning device, comprising: a processor, a memory, and a chicken drinking system cleaning program stored in the memory, wherein the chicken drinking system cleaning program is executed by the processor to implement the steps of the chicken drinking system cleaning method as described above.

[0022] Fourthly, the present invention also provides a computer-readable storage medium storing a chicken drinking system cleaning program, which, when executed by a processor, implements the chicken drinking system cleaning method as described above.

[0023] This invention utilizes a synergistic combination of drying and ventilation to disrupt the structure of the biofilm, followed by pulsed high-pressure water jet mechanical stripping. The drying pretreatment disrupts the biofilm's structural integrity, while the pulsed impact specifically targets these structural defects to achieve interfacial stripping. This method significantly improves the removal rate of mature, dense biofilms compared to high-pressure rinsing alone. Furthermore, it achieves stable biofilm control without the need for chemical agents, eliminating reliance on chemical reagents, saving on reagent procurement and labor costs, and is easy to implement for continuous daily control. Detailed Implementation

[0024] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0025] In this invention, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] This invention provides a first embodiment of a method for cleaning a chicken's drinking water system. In this embodiment, the method for cleaning a chicken's drinking water system is performed periodically within the normal breeding cycle of the chickens, specifically once a day or once every 2-3 days, depending on actual needs. The method for cleaning a chicken's drinking water system includes the following steps:

[0027] Drain the water from the drinking water pipes and keep the inside of the pipes in a dry and ventilated state for 2-3 hours to allow the extracellular matrix of the biofilm on the inner wall of the pipes to lose water, shrink and crack, and reduce the interfacial adhesion between the biofilm and the pipe wall.

[0028] It should be noted that under normal hydration, the EPS matrix of the biofilm is gel-like, possessing high elasticity and strong interfacial adhesion. Water shear force can only erode the surface layer, making interfacial peeling difficult. After the pipe is emptied, the biofilm is exposed to the air. Due to moisture loss, the EPS shrinks in volume, generating numerous microcracks within the membrane and at the interface between the membrane and the pipe wall. This can reduce cohesion and interfacial adhesion by 40%–60%, providing natural stress concentration points for subsequent mechanical peeling. Existing research and experiments have verified that 2–3 hours is the optimal range for biofilm drying and cracking under normal conditions with a relative humidity of 50%–60%. Too short a time results in a lower degree of biofilm drying and cracking, with minimal reduction in adhesion, while too long a time leads to hardening of the extracellular matrix and a recovery in adhesion. When the relative humidity changes, the drying time can be extended or shortened accordingly to achieve the same effect of extracellular matrix drying and reduced adhesion. The core mechanism of the drying effect is the shrinkage of extracellular polymeric water loss. Ambient humidity only affects the rate of water loss and does not change the final action law. Those skilled in the art can adjust the drying time according to the on-site humidity, which is all within the scope of this solution.

[0029] Specifically, the drain valve at the end of the pipe can be opened to drain the stored water, while keeping the water inlet of the pipe open to the atmosphere, forming a continuous natural convection air path to ensure a continuous decrease in humidity inside the pipe. For high-humidity environments, a small axial flow fan can also be installed at the water inlet for forced ventilation to further accelerate the drying rate. The 2-3 hour drying time in this solution is based on the continuous convection ventilation conditions.

[0030] Pulsed high-pressure water flow is introduced into the drinking water pipes to peel off the dried and loose biofilm;

[0031] It should be noted that steady-state water flow typically generates shear force parallel to the pipe wall, acting almost exclusively on the biofilm surface, and is a unidirectional, continuous force. The biofilm gradually adapts to the shear force of the water flow. This invention uses pulsed high-pressure flushing to generate a water hammer effect, forming a radial pressure shock wave perpendicular to the pipe wall. This shock wave can directly penetrate into the microcracks within the biofilm, acting like a wedge to rapidly expand the cracks and reach the interface between the membrane and the pipe wall, ultimately achieving complete biofilm peeling. This precisely matches the crack structure generated by the drying pretreatment, releasing the pre-existing advantage of reduced adhesion due to biofilm cracking. Furthermore, the pulsed flushing involves alternating cycles of impact and depressurization, creating alternating fatigue damage to the cracked biofilm. Under repeated stress, the biofilm is more likely to detach in whole sheets. Moreover, pulsed flushing only reaches peak pressure momentarily, remaining at low pressure for most of the time. The average pressure is much lower than continuous high pressure, ensuring the peak impact force required for peeling while significantly reducing fatigue wear on pipes and fittings, adapting to the daily cyclical maintenance rhythm. Furthermore, the flow rate of pulsed water is significantly lower than that of continuous water supply in the same amount of time, which reduces the rate of biofilm water absorption and recovery, resulting in better cleaning and ensuring the reliability of the invention. Specifically, the pulsed high-pressure water flow can be achieved through a combination of a pressure-stabilizing booster pump and a high-speed solenoid valve: the booster pump maintains a stable set water pressure in the inlet pipeline, and the controller controls the solenoid valve at the inlet end of the pipeline to open and close rapidly according to a set on / off cycle, generating a water hammer-type pulse pressure wave with a steep rising edge.

[0032] The detached biofilm fragments are discharged from the end of the pipe with the flushing water flow, and then the normal water supply pressure of the pipe is restored, and the pipe enters the daily water supply state.

[0033] After the biofilm fragments are washed away, normal water supply can be restored without the need for empty pens or production stoppages. This solves the problem of periodic water quality deterioration caused by traditional batch cleaning and can maintain stable drinking water quality that meets standards for a long time.

[0034] Simply drying without water can only reduce biofilm adhesion, but it cannot cause it to detach naturally; the biofilm will quickly absorb water and recover after water supply is restored. A single high-pressure pulse can only peel off the loose surface structure, with a weak effect on biofilm removal. This invention uses a combination of drying and ventilation to damage the biofilm structure, followed by pulsed high-pressure water flow for mechanical peeling. The drying pretreatment disrupts the integrity of the biofilm structure beforehand, and the pulsed impact specifically utilizes structural defects to achieve interface peeling. This method achieves a much higher removal rate for mature, dense biofilms than single high-pressure rinsing, significantly improving biofilm removal efficiency. Furthermore, it achieves stable biofilm control without the need for chemical agents, eliminating reliance on chemical agents, saving on agent procurement and labor costs, and is easy to implement for continuous daily control.

[0035] In one embodiment, the evacuation operation is initiated 3-3.5 hours before the preset lighting time in the chicken coop the following day, and the pulsed high-pressure water flow operation is performed 20-40 minutes before the preset lighting time. This ensures that the effective drying time remains consistently within the optimal range of 2-3 hours, ensures that the biofilm adhesion decreases to its peak level, and that the cleaning effect is stable and repeatable, thus improving the reliability of the invention. The rinsing and drainage are completed just before the lighting time, and the pipes are pre-filled with clean drinking water, allowing the chickens to drink normally as soon as the lights are turned on, without interfering with the normal drinking rhythm and production pace of the livestock and poultry, ensuring the practicality of the invention.

[0036] Furthermore, the emptying operation should be carried out no earlier than 20 minutes after the lights are turned off in the chicken house, to better suit the chickens' nighttime drinking habits: a buffer period should be reserved after the lights are turned off to ensure that the chickens complete their last drinking behavior, avoid sudden water shortage that could cause stress to the livestock and poultry, and ensure stable breeding welfare and production performance.

[0037] In one embodiment, the peak pressure of the pulsed high-pressure water flow is 0.3~0.75MPa, the duration of a single pulse is 1s, the interval between two adjacent pulses is 5s, and a total of 8~12 pulse flushing cycles are performed. This peak pressure is approximately 2~3 times the daily water supply pressure of a large-scale chicken farm, and can be adjusted according to the actual daily water pressure on site to ensure a balance between cleaning effect and equipment safety. This parameter combination can generate water hammer shock waves of appropriate intensity, precisely acting on the cracked interface of the dried biofilm to maximize peeling efficiency and achieve optimal synergy with drying pretreatment. Furthermore, the pressure and pulse intensity are adapted to the tolerance limits of conventional drinking pipes and nipple drinkers, preventing leakage at pipe joints, damage to seals, or nipple water output failure, thus balancing cleaning effect and equipment lifespan. The single pulse water flow duration is set at 1 second, optimized based on the length of drinking water pipelines in large-scale chicken houses and the propagation characteristics of water hammer pressure waves. The pressure wave can propagate throughout a 100-meter-long pipeline within 0.3 seconds, maintaining a stable peak pressure for the remaining time. This ensures effective impact throughout the entire pipeline while avoiding excessive pulse duration leading to impact attenuation, achieving an optimal balance between stripping effect and energy consumption. For drinking water pipelines exceeding 150 meters in length, a zone control valve can be used to divide the pipeline into two sections, performing pulse flushing sequentially; alternatively, adjusting the single pulse water flow duration to 1.2~1.5 seconds will ensure stable and compliant pressure throughout the pipeline.

[0038] Furthermore, after the pulsed high-pressure water flushing is completed, the high-pressure water flow is maintained for 30-60 seconds. The continuous high-pressure water flow can push all the detached biofilm fragments to the end of the pipe for discharge, preventing fragments from remaining in the middle of the pipe or getting stuck in the nipple water dispenser, thus preventing nipple blockage and secondary pollution, ensuring smooth and clean subsequent water supply, further improving the cleaning effect and the reliability of the invention.

[0039] In one embodiment, before draining the water from the drinking water pipe, the pipe is pre-flushed at normal pressure for 30-60 seconds using the daily water supply pressure. This pre-flushing removes loose suspended matter and biofilm debris from the inner surface of the drinking water pipe, preventing loose impurities from solidifying and adhering to the pipe wall during the ventilation and drying stage. This allows the drying and pulse action to directly target the firmly attached biofilm at the bottom layer, improving the cleaning effect of the present invention.

[0040] In one embodiment, the invention further includes: starting the timer from the start of the purging operation, and when the water supply interruption in the drinking water pipeline reaches 4 hours, restoring normal water supply to the drinking water pipeline and triggering an alarm. Setting an overtime protection threshold activates automatic protection in extreme situations such as valve failure or program malfunction, preventing prolonged water outages from causing water shortages in chickens and reducing the probability of production risk accidents; triggering the alarm facilitates timely intervention and troubleshooting by maintenance personnel, improving the operational safety and reliability of the invention.

[0041] To verify the biofilm removal effect of the cleaning method of the present invention, a control experiment was conducted, the specific process of which is as follows:

[0042] 1. Experimental materials and conditions

[0043] The φ25mm PVC-U (rigid polyvinyl chloride) drinking water pipes commonly used in large-scale chicken farms are cut into 10cm long standard pipe sections as biofilm attachment carriers. The inner wall is kept smooth and sterilized under high pressure before use.

[0044] The inoculation source was taken from the drinking water sample of a large-scale laying hen house. A 1 / 10 concentration of sterile nutrient broth culture medium was added to simulate the actual water quality and nutrient conditions of the hen house. The sterilized tube section was completely immersed in the inoculation solution and cultured at a constant temperature of 28℃ for 10 days. Fresh culture medium was replaced every 2 days to form a mature and dense tube wall biofilm.

[0045] The test environment temperature was controlled at 25℃ and the relative humidity was 50%~60%; the peak pressure of all flushing groups was uniformly set at 0.45MPa, and the total water flow time was kept consistent to ensure the principle of single variable.

[0046] 2. Experimental grouping and treatment

[0047] Take the cultured tube segments and gently rinse them three times with sterile deionized water to remove surface bacteria. Randomly divide the samples into 6 groups, with 3 replicates per group. The average value of the results is taken. The treatment methods for each group are as follows:

[0048] Blank control group: No cleaning treatment was performed, and the initial dry weight of the pipe wall deposits was directly measured.

[0049] Comparative Example 1 (Single Steady-State High-Pressure Flushing): Without drying pretreatment, the inner wall of the pipe section is directly flushed with steady-state high-pressure water flow at a peak pressure of 0.45MPa. The total water flow time is the same as the total water flow time of the pulse group.

[0050] Comparative Example 2 (Single Pulse High-Pressure Flushing): No drying pretreatment was used. A pulse high-pressure water flow with a peak pressure of 0.45 MPa was used for flushing. The parameters were 1 second water flow and 5 seconds water cut-off, and the cycle was repeated 10 times.

[0051] Comparative Example 3 (Single Drying Treatment): The product was simply placed in a ventilated environment and dried for 2.5 hours without any rinsing treatment;

[0052] Comparative Example 4 (drying + steady-state high-pressure rinsing): First, air dry for 2.5 hours, then rinse with steady-state high-pressure water flow with the same parameters as Comparative Example 1;

[0053] Example group (method of the present invention): First, air dry for 2.5 hours, then rinse with pulsed high-pressure water flow with the same parameters as Comparative Example 2.

[0054] 3. Measurement Method

[0055] The dry weight of the deposits on the tube wall was determined using an ultrasonic elution-filtration and drying method. Deionized water was used as the elution medium to avoid interference from residual inorganic salt crystals on the gravimetric results. The specific steps are as follows:

[0056] (1) The treated tube segment was placed in a conical flask containing 100 mL of sterile deionized water and sealed. It was then placed in a 40 kHz ultrasonic cleaner for ultrasonic elution for 10 minutes. Preliminary experiments verified that the elution rate of the biofilm on the tube wall reached a plateau under this ultrasonic condition, which can be considered as complete elution.

[0057] (2) The eluent was vacuum filtered through a 0.22 μm microporous membrane that had been pre-dried to constant weight to retain all solid deposits.

[0058] (3) Place the filter membrane containing the adhering material in an oven at 105°C and dry it to constant weight. Take it out and put it in a desiccator to cool to room temperature. Weigh it and subtract the weight of the filter membrane itself to get the dry weight of the adhering material on the tube wall of the sample.

[0059] The dry weight removal rate of pipe wall deposits is calculated using the following formula:

[0060] Pipe wall deposit dry weight removal rate = (Average dry weight of blank control group - Average remaining dry weight of treated group) / Average dry weight of blank control group × 100%

[0061] 4. Experimental Results and Analysis

[0062] The results of the dry weight removal rate of pipe wall deposits for each group are shown in the table below:

[0063] Group Handling method Clearance Blank control group No action taken 0 Comparative Example 1 Single steady-state high-pressure flushing 19.2% Comparative Example 2 Single pulse high-pressure flushing 27.6% Comparative Example 3 Single drying process 3.1% Comparative Example 4 Drying + steady-state high-pressure flushing 41.8% Example group Drying + Pulse High-Pressure Flushing 89.2%

[0064] The experimental results show that drying alone is almost unable to cause biofilm to detach actively, and steady-state or pulse rinsing alone can only remove the loose surface structure. When used alone, the cleaning effect is very limited.

[0065] Based on the arithmetic and calculation of the effects of individual methods, the expected removal rate of drying (3.1%) + steady-state flushing (19.2%) was 22.3%, while the actual removal rate after combination was 41.8%, indicating a synergistic gain. However, this gain stems from the decrease in biofilm adhesion caused by drying, which allows more surface biofilm to be detached with the same water flow shear force. Essentially, it is a linear relationship between the reduced adhesion and the increased flushing efficiency.

[0066] Based on the arithmetic and calculation of the effects of individual methods, the expected removal rate of drying (3.1%) + pulse flushing (27.6%) was 30.7%, while the actual removal rate after combination reached 89.2%, with a synergistic gain far exceeding that of the former. This difference indicates that the synergistic mechanism of pulse flushing is not solely due to the increased flushing efficiency resulting from reduced adhesion, but rather to the unique matching mechanism formed by the microcracks generated by drying and the radial shock waves of the pulsed water hammer. This allows the impact force to reach the bonding interface between the membrane and the tube, achieving full-layer peeling.

[0067] This invention combines drying pretreatment with directional pulsed high-pressure rinsing, achieving a removal rate of 89.2%, far exceeding the arithmetic sum of the effects of the two individual methods, and also significantly higher than the combined effect of drying and steady-state rinsing. Therefore, the two methods produce a significant synergistic effect through the matching action of "drying to create microcracks + pulsed shock wave wedging into the interface."

[0068] Based on the same inventive concept, this invention also proposes a cleaning device for a chicken drinking system, comprising: a drainage module for draining the water stored in the drinking pipe and maintaining the ventilation state between the inside of the pipe and the outside air; a pressurized water supply module for outputting an adjustable pressure pulsed high-pressure water flow; and a control module electrically connected to the drainage module and the pressurized water supply module respectively, for controlling the automatic execution of the draining, drying, and pulse rinsing processes according to a preset time sequence.

[0069] The technical solution in this embodiment achieves a synergistic effect of drying pretreatment to disrupt the biofilm structure and pulsed impact to achieve interface peeling through the coordinated operation of the drainage module and the pressurized water supply module. This results in a significantly higher removal rate of mature, dense biofilms compared to high-pressure rinsing alone, thus improving the overall biofilm removal efficiency. Furthermore, it achieves stable biofilm control without the need for chemical agents, eliminating reliance on chemical reagents, saving on reagent procurement and labor costs, and facilitating continuous daily control. The structural design is simple and rational, allowing for direct integration with existing large-scale farm drinking water systems, resulting in low hardware modification costs and minimal implementation difficulty.

[0070] This invention also proposes a chicken drinking system cleaning device, comprising: a processor, a memory, and a chicken drinking system cleaning program stored in the memory. The chicken drinking system cleaning program, when run by the processor, implements the steps of the chicken drinking system cleaning method described above. It enables fully automated operation of the cleaning process, requiring no manual intervention. Timing and parameter control are precise and stable, and it can be automatically executed in conjunction with the chicken house lighting system, significantly reducing manual maintenance costs and adapting to the management needs of large-scale, intensive farming. Furthermore, the beneficial effects of using the same method will not be elaborated further.

[0071] Furthermore, this invention also proposes a computer-readable storage medium storing a chicken drinking system cleaning program. When executed by a processor, the chicken drinking system cleaning program implements the chicken drinking system cleaning method described above. Therefore, it will not be repeated here.
