Description

Technical Field

[0001] The invention belongs to the technical field of water treatment, and relates to a natural water body self-cleaning filtration system used in a natural water body drip irrigation system, and a method for realizing self-cleaning filtration by using the system. Background Art

[0002] In modern agricultural irrigation systems, drip irrigation technology is widely used due to its high efficiency, water saving and precise fertilization. However, the core component of the drip irrigation system, the filter, often encounters blockage during use, which has become the main technical obstacle limiting the performance and life of the drip irrigation system.

[0003] When filtering river water or other natural water sources, the filter will capture impurities such as river sand, silt, microorganisms, etc. These impurities gradually accumulate inside the filter, resulting in a decrease in filtration efficiency and eventually completely clogging the filter.

[0004] The filters used in some drip irrigation systems are oversimplified in design and cannot effectively handle the filtering needs of sandy water. In sandy water conditions, these filters quickly lose their filtering capacity.

[0005] In drip irrigation systems using biological slow filtration technology, the formation of biofilm helps remove organic matter from the water, but it can also cause filter clogging. The growth and shedding of biofilm will further aggravate the clogging of the filter.

[0006] In the process of implementing the present invention, the inventors found that the prior art has at least one of the following technical problems:

[0007] 1. The maintenance of the drip irrigation system is often neglected, and the necessary inspection and cleaning are lacking. This leads to poor operation of the system, and the filter blockage problem cannot be solved in time, which in turn affects the performance of the entire drip irrigation system.

[0008] 2. The filter is frequently clogged in the river water drip irrigation system, resulting in high maintenance costs and low efficiency. In order to solve the problem of filter clogging, the existing technology usually adopts the method of regular cleaning and maintenance.

[0009] 3. In ecological restoration projects such as arid river valleys, frequent blockage and inconvenient maintenance of filters, especially in areas with rugged terrain and inconvenient transportation, greatly increase the operating difficulty and cost of the drip irrigation system. Summary of the invention

[0010] In view of the limitations of the prior art, the present invention aims to provide a natural water self-cleaning filtration system and filtration method to reduce the clogging problem of the filter, reduce maintenance costs, and improve the operating efficiency of the drip irrigation system. Through innovative structural design and automatic cleaning mechanism, the present invention can effectively solve the problems existing in the prior art and provide a more reliable and economical solution for modern agricultural irrigation.

[0011] In order to solve the above technical problems, the technical solution provided by the present invention is to provide a natural water self-cleaning filtration system, comprising:

[0012] The separation container is used to separate impurities in the water body; the separation container is a conical container, including a top plate, an outer cylinder, an inner tube body and a bottom tube; a water outlet pipe is arranged in the middle of the top plate; a water inlet pipe is arranged on the upper part of the outer cylinder body, the top of the inner tube body is connected to the lower surface of the top plate, the bottom of the inner tube body is open, an annular flow channel is formed between the inner tube body and the outer cylinder body, and the bottom tube is connected to the dirt storage box;

[0013] A dirt storage box, arranged below the separation container, for storing separated impurities;

[0014] A first solenoid valve, used for remotely controlling the opening and closing of the water outlet pipe;

[0015] The second solenoid valve is used to remotely control the opening and closing of the sewage pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The conical separation container design adopted by the system promotes the separation of impurities in the water under the action of centrifugal force through the annular flow channel formed by the inner tube body and the outer cylinder, thereby improving the filtration efficiency. The dirt storage box is designed to collect the separated impurities, reduce the cleaning frequency of the system, and reduce the interference of impurities on the drip irrigation system. Through the remote control of the first and second solenoid valves, the automatic opening and closing of the water outlet pipe and the sewage pipe is realized, which simplifies manual operation and reduces maintenance costs. By reducing the need for manual cleaning, the risk of system failure caused by improper maintenance is reduced, and the reliability and service life of the drip irrigation system are improved. The system is particularly suitable for areas with rugged terrain and inconvenient transportation, such as ecological restoration projects such as dry river valleys, and can achieve efficient and low-maintenance drip irrigation system operation in these areas.

[0018] On the basis of the above technical solution, the present invention can also be improved as follows:

[0019] Furthermore: it also includes an ultraviolet lamp tube installed in the separation container to kill microorganisms in the water body.

[0020] Preferably: a lamp tube mounting frame is arranged below the top plate, and an ultraviolet lamp tube is mounted on the lamp tube mounting frame; the ultraviolet lamp tube is vertically mounted in the inner tube body.

[0021] Compared with the prior art, the beneficial effect of adopting the above further technical solution is that by installing the ultraviolet light tube in the separation container, the present invention can effectively kill microorganisms in the water body, which not only improves the water quality, but also reduces the filter clogging problem caused by the accumulation of microorganisms. The addition of the ultraviolet light tube further enhances the self-cleaning function of the system, and prevents the formation of biofilm by destroying the DNA structure of microorganisms, thereby reducing the maintenance requirements of the system and extending the service life of the filter.

[0022] On the basis of the above technical solution, the present invention can also be improved as follows:

[0023] Furthermore, it also includes an ultrasonic generator, which is installed in the dirt storage box and is used to promote the separation of impurities.

[0024] Preferably, the ultrasonic generator comprises a vibrating rod, and the vibrating rod is arranged in the dirt storage box.

[0025] Preferably, a generator mounting hole is provided on the top of the dirt storage box, and the ultrasonic generator is mounted on the generator mounting hole.

[0026] Compared with the prior art, the beneficial effects of adopting the above further technical solution are:

[0027] By installing an ultrasonic generator in the dirt storage box, the impurities in the dirt storage box can be effectively removed. This high-frequency vibration can loosen the stubborn impurities attached to the inner wall of the dirt storage box, thereby improving the cleaning efficiency and reducing the need for manual cleaning. The addition of the ultrasonic generator significantly enhances the self-cleaning ability of the system. Through the mechanical vibration of sound waves, impurities are more easily removed from the inner wall of the dirt storage box and discharged, which can more effectively prevent the accumulation of impurities and filter clogging, and extend the maintenance cycle of the filter.

[0028] Furthermore: a filter screen is also provided at the bottom opening of the inner tube body.

[0029] Preferably, the filter screen is a flat screen or a conical filter screen, and the tip of the conical filter screen faces downward.

[0030] Furthermore, it also includes an IoT gateway and multiple sensors. The IoT gateway connects all sensors and actuators and transmits data to a cloud server or a local monitoring system through the network.

[0031] The present invention also provides a filtering method using the aforementioned natural water body self-cleaning filtering system, comprising the following steps:

[0032] S1, turn on the water pump to supply water to the separation container;

[0033] S2, turn on the ultraviolet light tube to kill microorganisms in the water body with ultraviolet light;

[0034] S3, opening the first solenoid valve and closing the second solenoid valve at the same time, and the filtration system provides filtered water to the drip irrigation system;

[0035] The method further includes the following steps before step S2 and / or after step S3:

[0036] Step A: Open the second solenoid valve and close the first solenoid valve to flush the impurities in the dirt storage box.

[0037] Preferably, the step A further comprises the following steps:

[0038] Start the ultrasonic generator to make the impurities attached to the inner wall of the dirt storage box fall off and evenly mix them into the water in the dirt storage box, making it easier to clean the dirt storage box.

[0039] Compared with the prior art, the beneficial effects of adopting the above further technical solution are:

[0040] By adding the step of ultraviolet light tubes to the filtering method, the present invention can not only effectively kill microorganisms in the water body and improve water quality, but also reduce filter blockage caused by microbial accumulation, thereby improving the operating efficiency of the entire filtering system. By accurately controlling the opening and closing of the first solenoid valve and the second solenoid valve, the filtering method of the present invention can realize automatic flushing of impurities in the dirt storage box, optimize the maintenance process, reduce the need for manual cleaning, and reduce maintenance costs. The use of an ultrasonic generator is added to the filtering method to further enhance the self-cleaning ability of the system, promote the separation of impurities through sound wave vibration, make the filter cleaning more thorough, extend the service life of the filter, and improve the reliability of the drip irrigation system.

[0068] The following is a description with reference to the accompanying drawings and a specific embodiment.

[0069] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0070] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0071] Example 1

[0072] See also Figures 1 to 7 In this embodiment, a natural water self-cleaning filtration system is described, and its detailed composition and working process are as follows:

[0073] Separation container 100: This container is the core component of the filtration system and is used to separate impurities in the water. The separation container 100 is designed as a conical structure, which helps to promote the formation of vortex flow of water inside the container, thereby improving the separation efficiency.

[0074] Top plate 110: located at the top of separation container 100, with a water outlet pipe 111 disposed in the middle thereof for discharging filtered clean water.

[0075] The outer cylinder 120 is an external structure of the separation container 100, and a water inlet pipe 121 is disposed on the upper portion thereof. The water inlet pipe 121 is designed to allow water to enter the outer cylinder 120 in a tangential direction, thereby promoting the water to form a vortex flow.

[0076] Inner tube body 130: Made of transparent material, the top is connected to the lower surface of top plate 110, and the bottom is open. The annular flow channel formed between inner tube body 130 and outer cylinder body 120 is the key area for water flow and impurity separation.

[0077] Bottom pipe 140 : connects the bottom of separation container 100 with dirt storage box 200 , and is used to transport separated impurities to dirt storage box 200 .

[0078] Dirt storage box 200: located below the separation container 100, used to collect and store the separated impurities. The design of the dirt storage box 200 allows centralized processing and regular discharge of impurities.

[0079] The first solenoid valve 510 is used to remotely control the opening and closing of the water outlet pipe 111, thereby controlling the output of filtered water.

[0080] The second solenoid valve 520 is used to remotely control the opening and closing of the sewage pipe 210 and to discharge the impurities in the sewage storage tank 200 periodically or as needed.

[0081] The working process of the system is as follows: first, the water pump 600 is turned on to supply water to the separation container 100 through the water inlet pipe 121. The water enters the outer cylinder 120 in a tangential direction to form a vortex flow. The water flows in the annular flow channel between the inner tube body 130 and the outer cylinder 120, and uses centrifugal force to separate impurities to the bottom of the outer cylinder 120, and transports the impurities to the dirt storage tank 200 through the bottom pipe 140. The filtered clean water flows out through the outlet pipe 111, and the first solenoid valve 510 controls the opening and closing of the outlet pipe 111 during this process to adjust the water flow. When the impurities in the dirt storage tank 200 accumulate to a certain extent, the second solenoid valve 520 is opened to discharge the impurities through the sewage pipe 210. At the same time, the first solenoid valve 510 is closed to ensure the smooth progress of the sewage discharge process. When the system needs to be cleaned, the dirt storage tank 200 can be flushed by opening the second solenoid valve 520, and the first solenoid valve 510 is closed at the same time to ensure the cleaning effect.

[0082] Optionally, the design of the natural water self-cleaning filtration system may also incorporate modern Internet of Things (IoT) technology to make the control of the first solenoid valve 510 and the second solenoid valve 520 more intelligent and remote.

[0083] IoT Gateway: As the core of the system, it connects all sensors and actuators (such as the first solenoid valve 510, the second solenoid valve 520 and the water pump 600, as well as the UV lamp 300 and the ultrasonic generator 400 in a further embodiment), and transmits data to the cloud server or the local monitoring system through the network.

[0084] The sensors, including water flow sensors, water quality sensors, flow sensors, and pressure sensors, are used to monitor the status of the separation container 100 and the dirt storage tank 200 in real time. The sensors collect the status data of the separation container 100 and the dirt storage tank 200 in real time. The IoT gateway performs a preliminary analysis on the collected data and decides whether to adjust the working status of each actuator according to the preset logic and conditions. Through the IoT gateway, the operator can remotely control the opening and closing of the first solenoid valve 510 and the second solenoid valve 520 to achieve the output of filtered water and the discharge of impurities. The system can automatically adjust the first solenoid valve 510 and the second solenoid valve 520 according to the feedback from the sensor to maintain the best filtering effect and system efficiency.

[0085] See also Figure 1The water pump 600 is directly connected to the water inlet pipe 121, and is responsible for extracting water from the water source and delivering it to the separation container 100, providing a continuous and stable water flow for the filtration system. This configuration ensures that the water body has sufficient pressure and flow rate before entering the separation container 100 for impurity separation and microbial killing, thereby improving the effect and efficiency of the entire filtration system.

[0086] See also Figure 4 According to a further embodiment of the natural water body self-cleaning filtration system of the present invention, the natural water body self-cleaning filtration system in this embodiment also includes an ultraviolet lamp 300 to enhance the self-cleaning ability of the system and improve the water quality. The ultraviolet lamp 300 is installed in the separation container 100 and is used to kill microorganisms in the water body. By integrating the ultraviolet lamp 300 in the system, this embodiment can not only effectively kill microorganisms in the water body and improve water quality, but also reduce filter clogging caused by microbial accumulation, thereby improving the operating efficiency and maintenance cycle of the entire filtration system. In addition, the addition of the ultraviolet lamp 300 also enhances the self-cleaning ability of the system, reduces the need for manual cleaning, and reduces maintenance costs.

[0087] See also Figure 4 and Figure 7 According to a further embodiment of the natural water body self-cleaning filtration system of the present invention, a lamp tube mounting frame 112 is provided below the top plate 110 of the natural water body self-cleaning filtration system in this embodiment, and an ultraviolet lamp tube 300 is installed on the lamp tube mounting frame 112; the ultraviolet lamp tube 300 is vertically installed in the inner tube body 130. By integrating the ultraviolet lamp tube 300 in the separation container 100, this embodiment not only improves the water quality and reduces biological contamination, but also enhances the self-cleaning ability of the system. The addition of the ultraviolet lamp tube 300 reduces the filter blockage caused by the accumulation of microorganisms, extends the maintenance cycle of the filter, and reduces the maintenance cost. In addition, since the ultraviolet lamp tube 300 is installed in the transparent inner tube body 130, it ensures that the water flow is fully exposed to ultraviolet light when passing through, thereby improving the disinfection efficiency. This design is both simple and efficient, and is an important improvement in the natural water body self-cleaning filtration system.

[0088] See also Figures 1-2 and Figure 4According to a further embodiment of the natural water body self-cleaning filtration system of the present invention, the natural water body self-cleaning filtration system in this embodiment also includes an ultrasonic generator 400, which is installed on the dirt storage tank 200 to promote the separation of impurities. The ultrasonic generator 400 is installed on the top or side of the dirt storage tank 200, and the specific installation position can be determined according to actual needs and design optimization. The ultrasonic generator 400 includes one or more ultrasonic transducers, which can convert electrical energy into ultrasonic energy. The ultrasonic generator 400 includes a vibrating rod 410, which is arranged in the dirt storage tank 200. As a part of the ultrasonic generator 400, the vibrating rod 410 is installed in the dirt storage tank 200 and directly contacts the water and impurities in the dirt storage tank. The vibrating rod 410 transfers ultrasonic energy to the water to generate high-frequency vibrations.

[0089] After the water body is processed by the separation container 100, the separated impurities flow into the dirt storage tank 200 through the bottom pipe 140. When the impurities in the dirt storage tank 200 accumulate to a certain extent, the ultrasonic generator 400 is started. The vibration rod 410 generates high-frequency ultrasonic vibrations, which propagate in the water in the dirt storage tank 200, causing violent vibrations of water molecules. The ultrasonic vibrations cause the water and impurities in the dirt storage tank 200 to produce a cavitation effect, forming tiny bubbles and collapsing quickly. This process generates a strong shock wave, which causes the impurities attached to the inner wall of the dirt storage tank 200 to fall off, and at the same time suspends the deposited impurities in the water. After the impurities are suspended by the ultrasonic vibration, the second solenoid valve 520 is opened, and the water containing impurities in the dirt storage tank 200 is discharged through the sewage pipe 210. This process can more thoroughly remove the impurities in the dirt storage tank 200 and reduce the need for manual cleaning. After the impurities are discharged, the second solenoid valve 520 is closed, and the system resumes normal operation, waiting for the next impurity collection and cleaning cycle.

[0090] By integrating the ultrasonic generator 400 into the natural water body self-cleaning filtration system, this embodiment not only improves the self-cleaning efficiency of the system, but also reduces the maintenance workload of the dirt storage box 200. The application of ultrasonic vibration makes it easier for impurities on the inner wall of the dirt storage box 200 to fall off and be discharged, thereby extending the cleaning cycle of the system, reducing maintenance costs, and improving the reliability and efficiency of the entire filtration system. This design is particularly suitable for application scenarios that are difficult to clean manually or require frequent cleaning, and provides an effective self-cleaning solution for the natural water body self-cleaning filtration system.

[0091] In a further embodiment of the present invention, the natural water self-cleaning filtration system is specially designed with an improved dirt storage tank 200, and a special generator mounting hole 220 is configured on the top. This mounting hole 220 is designed to fix and install the ultrasonic generator 400, so that the generator can directly act on the water and impurities in the dirt storage tank 200. Through this design, the ultrasonic generator 400 can more effectively transmit its vibration energy, promote the falloff of impurities attached to the inner wall of the dirt storage tank 200, and re-suspend the deposited impurities in the water for easy discharge through the sewage pipe 210. This integrated design not only improves the self-cleaning efficiency of the system, but also simplifies the structure of the system, making maintenance and operation more convenient. The precise positioning of the ultrasonic generator 400 also helps to optimize the cleaning effect and ensure that the impurities in the dirt storage tank 200 are effectively treated. See Figures 1 to 7 for a detailed view of this embodiment.

[0092] In a further embodiment of the present invention, the natural water self-cleaning filtration system adds an important component, a filter screen 131, at the bottom opening of the inner tube body 130. This filter screen 131 is designed to be a conical structure with its tip facing downward to enhance the filtering effect and promote the filtered water to flow more smoothly into the dirt storage tank 200 or be discharged through the bottom pipe 140. The setting of the conical filter screen 131 not only improves the interception ability of the separation container 100 for fine impurities in the water, but also helps to prevent clogging at the bottom of the inner tube body 130, ensuring the continuity of the water flow and the efficient operation of the filtration system. In addition, the conical design also facilitates the cleaning and replacement of the filter screen 131, simplifying maintenance work. This improvement makes the filtration system more perfect and can meet the needs of filtering water bodies containing more fine impurities.

[0093] Example 2

[0094] This embodiment describes in detail how to use the natural water self-cleaning filtration system described in Example 1 to perform filtration operations in combination with an Internet of Things system. The method includes the following steps:

[0095] S1: remotely start the water pump 600 to supply water to the separation container 100.

[0096] Through the IoT system, the operator can remotely control the start of the water pump 600 to extract natural water from the water source and transport it to the separation container 100 through the water inlet pipe 121. The IoT gateway receives the operation instruction and sends a start signal to the water pump through a wireless or wired connection to provide the necessary water pressure and flow for the entire filtration process.

[0097] S2: Automatically turn on the ultraviolet lamp tube 300 to kill microorganisms in the water body using ultraviolet light.

[0098] When the water flow sensor detects that water enters the separation container 100, the Internet of Things system automatically sends a signal to turn on the ultraviolet lamp 300 installed in the inner tube 130. The ultraviolet light emitted by the ultraviolet lamp 300 can effectively kill microorganisms in the water flowing through the separation container 100, reduce biological contamination, and improve water quality.

[0099] S3: Intelligently control the first solenoid valve 510 and close the second solenoid valve 520 at the same time, and the filtering system provides filtered water to the drip irrigation system.

[0100] The IoT system intelligently controls the opening of the first solenoid valve 510 and the closing of the second solenoid valve 520 according to the data from the water quality sensor and the flow sensor, so as to allow the filtered clean water to flow out through the outlet pipe 111 and be supplied to the drip irrigation system.

[0101] Step A: The condition triggers the second solenoid valve 520 to open and the first solenoid valve 510 to close to flush the impurities in the dirt storage box 200.

[0102] When the impurity concentration in the dirt storage tank 200 reaches a preset threshold, or when the water pump 600 is started, or after a single drip irrigation task is completed, the Internet of Things system automatically opens the second solenoid valve 520 to open the sewage pipe 210, and at the same time closes the first solenoid valve 510 to divert the water flow to the dirt storage tank 200 to flush and discharge the impurities therein.

[0103] When executing step A: the ultrasonic generator 400 is started to make the impurities attached to the inner wall of the dirt storage box 200 fall off and be evenly mixed into the water in the dirt storage box 200, so as to facilitate the cleaning of the dirt storage box 200.

[0104] Based on step A, the Internet of Things system starts the ultrasonic generator 400 installed on the dirt storage box 200. The high-frequency vibration generated by the ultrasonic generator 400 causes the impurities attached to the inner wall of the dirt storage box 200 to fall off, and makes these impurities evenly mixed into the water, so that they are more easily carried away by the water flow, thereby achieving a thorough cleaning of the dirt storage box 200.

[0105] Through the filtration method described in this embodiment, the natural water self-cleaning filtration system combined with the Internet of Things system can not only effectively filter impurities and microorganisms in the water, but also maintain the long-term stable operation of the system through automated cleaning processes and intelligent control, reduce manual intervention, reduce maintenance costs, and improve the efficiency and reliability of the entire filtration system. The application of Internet of Things technology makes the operation of the filtration system more intelligent and remote, providing an innovative solution for modern water treatment.
