Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment, specifically to a multi-channel ultraviolet disinfection and sterilization device for planting liquid return. Background Technology

[0002] Modern agriculture mostly employs soilless cultivation techniques, which do not use traditional soil as the crop growth medium. Instead, they utilize water-soluble fertilizers and planting substrates (generally coconut coir) to provide the crops with the necessary nutrients, water, and root support. When the water-soluble fertilizers used for irrigation flow through the crop roots, some are absorbed, while the remainder is discharged through pipes. The portion that is not absorbed by the crops and is discharged is called planting return liquid. If the crop roots, the growing substrate, and the irrigation pipes are not cleaned for a long time, a large number of bacteria and viruses will grow. Generally, the planting return liquid is discharged after simple treatment. The discharged planting return liquid not only contains bacteria and viruses, but also fertilizers that have not been fully absorbed by the plants. The discharge and non-utilization of planting return liquid results in a great waste.

[0003] Currently, there are UV disinfection devices available on the market for liquids, but none specifically designed for disinfecting and sterilizing liquids from planting in modern agriculture. These liquids contain a large amount of planting substrate residue (such as coconut coir), which severely affects the penetration of ultraviolet light and reduces sterilization efficiency. Furthermore, conventional sterilization devices are single-channel with one inlet and one outlet, unable to achieve multi-inlet and multi-outlet functions (such as direct storage, circulating sterilization, and direct discharge). Therefore, there is an urgent need for a multi-channel UV disinfection and sterilization device for planting liquids that can sterilize and disinfect the liquids while simultaneously enabling direct storage, circulating sterilization, and direct discharge.

[0020] 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.

[0021] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1As shown, a multi-channel ultraviolet disinfection and sterilization device for planting return liquid includes, in sequence, pipe 3 (3), a self-priming pump 14, pipe 4 (4), a filter 17, pipe 5 (5), a UV sterilizer 18, and pipe 6 (6). The device also includes pipes 1 (1), 2 (2), 7 (7), 8 (8), and 9 (9). Pipe 3 is connected to a treated tank 21 via pipe 1, and also to an untreated tank 22 via pipe 2. Pipe 6 is connected to a drain outlet 19 via pipe 7, and also to a treated direct discharge outlet 20 via pipe 8. Pipe 6 is also connected to the treated tank via pipe 9. Pipes 1, 2, and 9... Pipes 3, 4, 5, 6, 8, and 9 are respectively equipped with valves 101, 201, 301, 401, 501, 601, 801, and 901. Pipe 5 is equipped with EC sensor 23 and pH sensor 24. Pipe 3 is equipped with flow meter 302. Pipe 3 is also connected to pipe 10. Pipe 10 is connected to clean water pipe 25. Pipe 10 is equipped with valve 1001. Pipe 4 is connected to pipe 11. Pipe 11 is connected to acid storage tank 16. Pipe 11 is equipped with metering pump 15.

[0023] The filter has a discharge port 1701, which is connected to pipe 12 12. Pipe 12 is connected to a sewage outlet, and valve 12 1201 is installed on pipe 12. Pipe 6 is connected to pipe 3, and valve 6 is installed on pipe 6. Pipe 4 is connected to pipe 13 13, and pipe 4 is connected to pipe 5 through pipe 13. Valve 13 1301 is installed on pipe 13. The end of pipe 13 furthest from pipe 4 is connected to the filter outlet. All pipes are made of high-pressure resistant PVC material.

[0024] The UV sterilizer contains multiple quartz tube sleeves 1802, each housing a corresponding ultraviolet lamp. It also includes an ultraviolet detection sensor and a cleaning ring 1803. The cleaning ring is fitted onto the outer wall of the multiple quartz tube sleeves, with its inner side contacting the outer wall. A rotatable screw is located on one side of each quartz tube sleeve, and a nut is threaded onto the cleaning ring and connected to the screw. A motor 1801 is connected to one end of the screw. When the ultraviolet sensor detects that the ultraviolet value is outside a preset range, the motor drives the screw to rotate, causing the cleaning ring to move back and forth, thus cleaning the outer wall of the quartz tube sleeves and ensuring effective sterilization. This is existing technology and will not be elaborated further.

[0025] Embodiment 1 of this utility model: When it is necessary to disinfect and sterilize the planting return liquid in the untreated tank, open valves 2, 3, 4, 5, and 8, while keeping the remaining valves closed. The self-priming pump starts, and the planting return liquid in the untreated tank flows sequentially through pipes 2, 3, and 4 under the action of the self-priming pump. The filter has an inlet and an outlet. The planting return liquid enters the filter through the inlet and flows out through the outlet. The outflowing planting return liquid passes through pipe 5. The EC sensor and pH sensor on pipe 5 measure the conductivity and pH value of the planting return liquid, providing effective and accurate data for precise fertilization in subsequent irrigation. UV disinfection... The sterilizer has an inlet and an outlet. The plant return solution enters the inlet of the UV sterilizer through pipe five. The UV sterilizer has multiple quartz tube sleeves inside, and multiple ultraviolet lamps are installed inside the quartz tube sleeves. The UV sterilizer also has an ultraviolet detection sensor inside. The UV sterilizer has a cleaning ring inside, which is fitted onto the outer wall of the multiple quartz tube sleeves. The cleaning ring has a cleaning collar, which contacts the outer wall of the quartz tube. The ultraviolet lamps disinfect and sterilize the plant return solution. After sterilization, it is discharged from the treated direct discharge port for subsequent irrigation. If irrigation is not needed temporarily, valve eight is closed and valve nine is opened to temporarily store the treated plant return solution in the treated tank.

[0026] Embodiment 2 of this utility model: The treated planting fluid stored in the treated tank can still accumulate a large number of viruses and bacteria after long-term storage, requiring regular circulation and disinfection. Valves 1, 3, 4, 5, and 9 are opened, while the remaining valves are closed. The planting fluid in the treated tube, under the action of a self-priming pump, sequentially passes through pipe 1, pipe 3, the self-priming pump, and pipe 4, entering the filter for filtration. After filtration, it enters the UV sterilizer through pipe 5 for disinfection, and then returns to the treated tank through pipes 6 and 9.

[0027] Embodiment 3 of this utility model: After a period of use, impurities, viruses, and bacteria will accumulate on the inner walls of the pipes, valves, and other components of the disinfection device, requiring regular soaking and rinsing with an acidic cleaning agent. Valves 10, 3, 4, 5, and 7 are opened, the self-priming pump is activated, and the remaining valves are closed. Clean water from the clean water pipe enters pipe 3 through pipe 10, passes through pipe 10, pipe 3, the self-priming pump, pipe 4, the filter, pipe 5, the UV sterilizer, and pipe 7, and finally exits from the drain outlet, thus cleaning the device. Afterward, valve 10 is closed, and valve 6 is opened. At this point, the device is in internal circulation mode. Due to the negative pressure generated by internal circulation, opening valve 7 will not cause internal clean water to exit from the drain outlet. During internal circulation, the metering pump starts, continuously adding acidic cleaning agent from the acid storage tank. Add the acidic cleaning agent to pipe four. Under the action of the self-priming pump, the acidic cleaning agent circulates in the pipe. After the pH sensor detects that the pH value has reached a certain value, the metering pump stops working, valve seven at the drain outlet closes, and the self-priming pump shuts off, so that the entire pipe is in a static soaking state. After soaking for a period of time, first open valve seven and start the self-priming pump to put the entire equipment back into an internal circulation state. The liquid flow in the pipe continuously flushes the pipe soaked in the acidic cleaning agent. After flushing for a period of time, open valve ten, and clean water enters the pipe and carries the liquid out from the drain outlet, thus completing the soaking, rinsing, and sewage discharge of the pipe.

[0028] When the filter fails to clean itself automatically, it can be backwashed to remove impurities from the filter's outlet. At this time, valves 10, 3, 13, and 12 should be opened. All other valves should be closed. Clean water, driven by the self-priming pump, flows through pipes 10, 3, 4, and 13 before entering the filter's outlet and flowing out through the discharge port. Finally, it is discharged through pipe 12 from the drain outlet.

[0029] When the pressure difference between the inlet and outlet of the filter is too large during use, valve twelve opens. The filter is equipped with a drive motor and a cleaning brush inside. The drive motor drives the cleaning brush to rotate, thereby cleaning the impurities attached to the filter screen and discharging them from the outlet under the impact of the water flow. This is existing technology and will not be elaborated here. During the automatic cleaning process of the filter, part of the liquid flows out from the filter outlet and part of the liquid is discharged from the filter outlet, which does not affect the overall efficiency of the equipment.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
