Description

TECHNICAL FIELD

[0001] The utility model relates to hydrogen-rich water agricultural irrigation technical field, concretely relates to a hydrogen-rich water agricultural irrigation equipment. BACKGROUND

[0002] With the development of agricultural science and technology and the improvement of people's health consciousness, new agricultural irrigation technology and its use materials are increasingly valued. Micro-nano hydrogen-rich water, as a new water treatment technology, has shown great application potential and value in the field of agricultural irrigation in recent years.

[0003] Micro-nano hydrogen-rich water refers to water in which abundant hydrogen molecules are dissolved through specific treatment, and these hydrogen molecules exist in the form of micro-nano bubbles. This water not only contains hydrogen elements, but also has unique physical properties that help improve water permeability and solubility, and has a positive effect on plant growth. At the same time, micro-nano hydrogen-rich water can also improve the soil environment and increase soil fertility, providing more favorable conditions for crop growth.

[0004] CN214881859U discloses a large-flow hydrogen-rich water preparation equipment for agricultural planting, which comprises a water pump, a hydrogen production module, a nano bubble gas-liquid mixer and a flow control module.

[0005] The above technical solution can produce hydrogen on site through the hydrogen production module, and hydrogen is produced on site by water electrolysis tank. The hydrogen pressure and yield are adjustable and controllable, and the efficient preparation of hydrogen-rich irrigation water can be realized. The hydrogen concentration is easy to reach saturation, and the hydrogen stays in water for a long time, which can meet the hydrogen concentration standard and irrigation flow demand required for the development of crops. However, the above technical solution only has a nano bubble gas-liquid mixer for one-step hydrogen mixing, the bubble size and distribution are uneven, the hydrogen dissolution efficiency is not high, and the hydrogen content of hydrogen-rich water decreases. UTILITY MODEL CONTENT

[0006] The purpose of the present application is to solve the above problems, and a hydrogen-rich water agricultural irrigation equipment is provided. The gas outlet pipe on the electrolysis unit is communicated with the water inlet pipe, so that the water input into the equipment is mixed with hydrogen for one-step hydrogen mixing. At the same time, the bubbles can be cut in the pump to realize two-step hydrogen mixing. The hydrogen is further mixed in the mixing unit to realize three-step hydrogen mixing. Through multi-stage hydrogen mixing, the hydrogen can be refined into smaller bubbles more effectively, and the solubility and stability of the gas are improved. The distribution of nano bubbles is more uniform, which helps to improve the effect of hydrogen-rich water.

[0007] To achieve the above purpose, the present application provides the following technical scheme:

[0008] A hydrogen-rich water agricultural irrigation device includes a frame, an electrolysis unit, a pump, and a hydrogen mixing unit connected within the frame. The frame is equipped with a water inlet and a water inlet pipe, which are connected to the electrolysis unit. The water inlet pipe is connected to the input end of the pump.

Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0017] Example 1

[0018] refer to Figures 1 to 3 A hydrogen-rich water agricultural irrigation device includes a frame 1, an electrolysis unit 2, a pump 3, and a hydrogen mixing unit 4 connected within the frame 1. The frame 1 is provided with a water inlet 11 and a water inlet pipe 12, which are connected to the electrolysis unit 2. The water inlet pipe 12 is connected to the input end of the pump 3. The electrolysis unit 2 is provided with a gas outlet pipe 211, which is connected to the water inlet pipe 12 and is used to transport hydrogen gas into the water inlet pipe 12. The output end of the pump 3 is connected to the hydrogen mixing unit 4. The hydrogen mixing unit 4 is provided with a water outlet pipe 43, which is connected to an external spraying device.

[0019] In this embodiment, pump 3 is a centrifugal pump. Under this design, the operator connects the inlet pipe 12 to an external water source and adds raw water to the inlet 11. The raw water is electrolyzed by the electrolysis unit 2 to generate hydrogen and oxygen. The hydrogen is transported to the inlet pipe 12 through the outlet pipe 211. Under the action of pump 3, the external water source is drawn and mixed with the hydrogen input through the outlet pipe 211 for a first hydrogen mixing. Then, in pump 3, the impeller cuts the bubbles for a second hydrogen mixing. The water output from pump 3 enters the hydrogen mixing unit 4 for a second hydrogen mixing. Finally, hydrogen water is output from the outlet pipe 43. The operator can also connect the external spraying device to the outlet pipe 43 to irrigate the plants.

[0020] In this way, multi-stage hydrogen mixing can more effectively refine hydrogen into smaller bubbles, improving the solubility and stability of the gas; the distribution of nanobubbles is more uniform, which helps to improve the effect of hydrogen-rich water.

[0021] It should also be noted that electrolysis unit 2 is for producing hydrogen by electrolysis of water.

[0022] In this embodiment, the electrolysis unit 2 includes an outer shell 21, an electrolysis device 22 connected inside the outer shell 21, and a pure water tank 23. The water inlet 11 is connected to the pure water tank 23, and the pure water tank 23 is used to transport pure water to the electrolysis device 22. The oxygen outlet of the electrolysis device 22 is connected to the pure water tank 23. The gas outlet pipe 211 is located on the outer shell 21, and the hydrogen outlet of the electrolysis device 22 is connected to the gas outlet pipe 211.

[0023] Specifically, pure water is used because it has a relatively high electrolysis efficiency. Impurities in water may affect the electrolysis reaction, leading to reduced efficiency. Furthermore, impurities (such as salts and minerals) may corrode and damage the electrolytic cell and electrodes. Using pure water can extend the service life of the equipment.

[0024] Implicitly, the pure water tank 23 is equipped with a control valve to control the flow rate of pure water entering the electrolysis device 22.

[0025] Preferably, a check valve 2111 is provided on the gas outlet pipe 211 to prevent hydrogen gas from flowing back into the electrolysis device 22 when it enters the water inlet pipe 12.

[0026] Preferably, the hydrogen mixing unit 4 includes a first aeration device 41, which includes a tank 411, an input pipe 412 connected to the tank 411, an outlet pipe 43 connected to the tank 411, the input pipe 412 being connected to the output end of the pump 3, an aeration pipe 413 being provided inside the tank 411, the output end of the input pipe 412 being connected to the aeration pipe 413, and a plurality of outlet holes 414 arranged in a circumferential array along the side of the aeration pipe 413.

[0027] In practical applications, the hydrogen-water mixture after being cut and mixed by pump 3 is only a preliminary hydrogen-water mixture. Under the action of pump 3, the hydrogen-water mixture is transported to the input pipe 412 and enters the aeration pipe 413 through the input pipe 412. Under the action of pressure, water is squeezed out from the water outlet 414 on the aeration pipe 413 and enters the tank 411. Under the action of squeezing, the hydrogen bubbles become more uniform and the concentration is higher.

[0028] Preferably, the tank 411 is equipped with a pressure relief valve 4111. Specifically, the pressure relief valve 4111 can monitor the pressure in the system. When the pressure exceeds the set value, it will automatically open to release part of the medium, thereby preventing the equipment from being damaged or exploding due to excessive pressure.

[0029] Furthermore, the hydrogen mixing unit 4 also includes a second aeration device 42, which includes a pipe body 421. The input end of the pipe body 421 is connected to the tank body 411, and the output end of the pipe body 421 is connected to the water outlet pipe 43. A unidirectional flow mechanism 422 and multiple aeration discs 423 are arranged sequentially along the conveying direction of the pipe body 421. The multiple aeration discs 423 are arranged at intervals, and multiple through holes 4231 are provided on the aeration discs 423.

[0030] In this embodiment, the unidirectional flow mechanism 422 plays two roles in the pipe body 421. First, it prevents backflow. Second, hydrogen water will only enter the area of ​​multiple aeration discs 423 when the pressure in the pipe body 421 reaches a preset value. This is because if the hydrogen water pressure is insufficient, it will not be able to achieve the cutting effect when it reaches the area of ​​the aeration discs 423, and it will be difficult to pass through the multiple aeration discs 423.

[0031] Under the action of the aeration disc 423, hydrogen and water pass through the through holes 4231 in the aeration disc 423 in sequence, cutting the bubbles again to form nano-sized bubbles. At the same time, multi-stage hydrogen mixing makes the bubbles more stable, and the size and distribution more uniform.

[0032] Specifically, the unidirectional flow mechanism 422 includes a fixed tube 4221, an elastic component 4222, and a baffle 4223. The outer wall of the tube 421 has a recess along its interior, and the recess forms a fixed part 4211 on the inner wall of the tube 421. The fixed tube 4221 has a flange 4224, and the fixed tube 4221 is connected to one side of the fixed part 4211 through the flange 4224. The fixed tube 4221 is connected to the baffle 4223 through the elastic component 4222, and one side of the baffle 4223 abuts against the other side of the fixed part 4211.

[0033] In practical applications, the elastic component 4222 is preferably a spring, and the elastic component 4222 is initially in a contracted state. At this time, the elastic component 4222 pulls the baffle 4223 to adhere to one side of the fixing part 4211, forming a sealing effect. When the incoming hydrogen water has a preset pressure, the hydrogen water will push the baffle 4223 open, so that there is a gap between the baffle 4223 and the fixing part 4211 for the hydrogen water to pass through. The hydrogen water enters the rest of the aeration plate 423. At this time, the elastic component 4222 is still in a contracted state. Until there is no hydrogen water or the hydrogen water pressure is insufficient, the spring pulls the baffle 4223 to reset and re-adhere to one side of the fixing part 4211, forming a sealing effect.

[0034] In this embodiment, a jet injector 5 is also included. The jet injector 5 is provided with a first input port at one end, a second input port on its side, and an output port at the other end. The output port is connected to the input end of the pump 3. The water inlet pipe 12 is connected to the first input port of the jet injector 5, and the air outlet pipe 211 is connected to the second input port.

[0035] Specifically, the ejector 5 can be a Venturi ejector, which forms a constricting throttling section in the pipe, causing the fluid velocity to increase and the pressure to decrease as it flows through this section, thereby generating a suction or jet effect. In the constricted section of the ejector 5, the increased flow velocity leads to a decrease in pressure, thus allowing hydrogen gas from the second inlet to be drawn in. Because the Venturi ejector 5 is prior art, it will not be described in detail in this embodiment.

[0036] Optionally, the bottom of the frame 1 is provided with support legs or lockable casters. Preferably, the bottom of the frame 1 is provided with lockable casters to facilitate the movement of the frame 1.

[0037] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
