Description

Technical Field

[0001] This utility model relates to the field of fertilizer technology, specifically to a fertilizer dissolving device that combines vortex circulation stirring with pneumatic stirring. Background Technology

[0002] In modern facility agriculture technology, integrated water and fertilizer irrigation is the most fundamental and crucial link. In common drip irrigation and sprinkler irrigation operations, fertilizer processing is paramount. Fertilizer must be fully dissolved, and all impurities must be thoroughly filtered out. Only in this way can clogging of the irrigation system be effectively avoided, ensuring that crops can successfully absorb and utilize these nutrients.

[0003] Currently, the common dissolution method involves installing a geared motor and a stirring rod on a fertilizer tank or bucket. The specific equipment configuration is as follows: a bracket is installed above the fertilizer bucket, and the geared motor is fixed to the bracket. The geared motor drives the stirring rod to rotate via a transmission device. The stirring rod is equipped with blades. When the equipment is running, the blades move horizontally in a circular motion within the solution, agitating the water and thus accelerating the dissolution of the fertilizer.

[0004] However, the aforementioned traditional methods have the following drawbacks and shortcomings: First, the equipment occupies the upper, central, and lower spaces of the fertilizer tank, making fertilizer application extremely inconvenient and causing obstacles for workers when adding fertilizer. Second, the included supports, reducers, stirring rods, and blades further increase the overall cost of the fertilizer tank, raising agricultural production costs. Third, solid fertilizer releases heat during dissolution and often adheres to the blades, making cleaning very troublesome, consuming a lot of time and manpower, and potentially affecting subsequent use due to incomplete cleaning. Fourth, the horizontally rotating blades result in a higher concentration of fertilizer solution at the bottom and a lower concentration at the top, leading to uneven concentration during fertilization, which in turn affects the uniformity and stability of crop growth and reduces the quality of agricultural production. Utility Model Content

[0005] The purpose of this invention is to propose a fertilizer dissolving device that combines vortex circulation stirring with pneumatic stirring. By combining vortex and pneumatic stirring, horizontal and vertical stirring are achieved, and the stirring efficiency is uniform, so as to solve the problems of uneven stirring, high agricultural costs, and the need for multiple devices in the background technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This utility model discloses a fertilizer dissolving device combining vortex circulation stirring and pneumatic stirring, including a fertilizer dissolving tank, a filter screen inside the fertilizer dissolving tank, and multiple vortex nozzles spaced apart along the circumferential direction on the tank wall. The vortex nozzle is connected to the pressure pump via a circulating water inlet pipe; The bottom center of the fertilizer dissolving tank is equipped with a pneumatic jet device, which is connected to an air pump through an air inlet pipe; The water jet from the vortex nozzle creates a horizontal vortex stirring effect inside the fertilizer dissolving tank, while the gas jet from the pneumatic jet device creates a vertical pneumatic stirring effect inside the tank. The combination of horizontal vortex stirring and vertical pneumatic stirring forms a three-dimensional stirring effect.

[0007] As a further improvement, the spray direction of the vortex nozzle forms a 40° to 50° angle with the wall of the fertilizer dissolving tank.

[0008] As a further improvement, the filter screen is vertically arranged along the inside of the fertilizer dissolving tank, which can divide the fertilizer dissolving tank into a first chamber and a second chamber; The first chamber is used to contain fertilizer, and the second chamber is used to store the filtered solution. As a further improvement, the volume of the first cavity is larger than that of the second cavity.

[0009] As a further improvement, a heating device is provided on the circulating water inlet pipe and / or the air inlet pipe. As a further improvement, the vortex nozzle is provided with a vortex inlet, which is connected to a circulating water inlet pipe.

[0010] As a further improvement, the pneumatic jet device is provided with a pneumatic air inlet, which is connected to the air inlet pipe.

[0011] As a further improvement, the pressurizing pump can be used for circulating pressurization during the fertilizer dissolution stage and for fertilizer pressurization during the fertilization stage.

[0012] As a further improvement, the pneumatic jet device is a microporous aeration head.

[0013] As a further improvement, the vortex nozzle is three in number.

[0014] Compared with the prior art, this utility model achieves the following technical effects: This invention achieves efficient and uniform mixing in the fertilizer dissolving device by combining vortex circulation stirring and pneumatic stirring, thereby improving the uniformity and efficiency of fertilizer dissolution. By combining horizontal vortex stirring with a vortex nozzle and vertical pneumatic stirring with a pneumatic jet device, three-dimensional stirring is formed, ensuring that the fertilizer solution in the dissolving tank is fully mixed in both horizontal and vertical directions. This effectively avoids the problem of high concentration at the bottom and low concentration at the top, which is common in traditional stirring methods, thus ensuring the overall uniformity of the fertilizer solution.

[0015] This invention also eliminates the need for traditional geared motors, stirring rods, and paddles, which not only reduces equipment manufacturing and maintenance costs but also simplifies the operation process, making the fertilization process more convenient and avoiding the equipment's occupation of operating space. At the same time, the combined use of vortex nozzles and pneumatic jet devices reduces the risk of fertilizer adhering to the equipment, making cleaning easier and further improving the practicality and durability of the device.

[0016] The vortex nozzle of this invention sprays water at a 40°–50° angle to the wall of the fertilizer dissolving tank, allowing the water flow to enter the solution at the optimal angle, generating a strong vortex effect. This enhances the coverage and intensity of horizontal stirring, thereby improving the dissolution rate and uniformity. The filter screen divides the fertilizer dissolving tank into a first chamber and a second chamber, achieving physical separation between the dissolution of solid fertilizer and the solution. This not only ensures the cleanliness of the final solution and prevents impurities from clogging the irrigation system, but also facilitates maintenance and cleaning.

[0017] The circulating water inlet pipe and / or air inlet pipe of this utility model can be equipped with a heating device as needed, which can heat the water flow or gas when the ambient temperature is low, promote the rapid dissolution of fertilizer, and is especially suitable for low temperature seasons or regions, thus enhancing the adaptability and practicality of the device.

Detailed Implementation

[0019] The embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. Rather, the embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The fertilizer dissolving tank 1 in this device is a container, which is usually cylindrical in shape and does not have a lid on top. The fertilizer dissolving tank 1 is preferably made of corrosion-resistant materials, such as polyethylene, polypropylene or stainless steel, to adapt to the chemical properties of the fertilizer solution.

[0021] In this embodiment, the filter screen 2 is vertically installed inside the fertilizer dissolving tank 1, dividing the internal space of the tank into a first chamber and a second chamber. The first chamber is mainly used to hold the fertilizer, and its volume is larger than that of the second chamber to provide sufficient space for the fertilizer to dissolve. The second chamber is used to store the filtered solution. The filter screen 2 in this embodiment adopts a detachable design, and its mesh size can be adjusted according to the size of the fertilizer particles. This effectively intercepts impurities without excessively obstructing the flow of water. The partitioned design not only achieves physical separation of dissolution and filtration but also simplifies the cleaning process, requiring only periodic cleaning or replacement of the filter screen 2.

[0022] The fertilizer dissolving tank in the embodiment can also be equipped with high and low liquid level sensors. The high and low liquid level sensors are combined with a pressure pump and a solenoid valve preferably installed on the water inlet pipe to realize automatic control of water addition and fertilizer injection.

[0023] In this embodiment, the vortex nozzles are evenly distributed circumferentially along the inner wall of the fertilizer dissolving tank 1. In this embodiment, the number of vortex nozzles is preferably three, namely a first vortex nozzle 3, a second vortex nozzle 4, and a third vortex nozzle 5, to form a stable triangular flow. However, the number of vortex nozzles can be increased or decreased according to the size of the tank.

[0024] Specifically, each vortex nozzle is connected to a pressure pump via a circulating water inlet pipe 8. The spray direction of the vortex nozzle forms a 40°–50° angle with the barrel wall, preferably 45° in this embodiment. This allows the water flow to impact the barrel wall tangentially, thereby creating a strong vortex inside the barrel. Specifically, when the water flow is sprayed at a 45° angle, it rotates along the barrel wall and swirls inward, generating a horizontal annular vortex. The outermost ring has the highest flow velocity, and the innermost ring has the lowest flow velocity. This flow not only covers a wide area but also lifts the fertilizer at the bottom upward, preventing sedimentation.

[0025] In this embodiment, the first vortex nozzle 3, the second vortex nozzle 4, and the third vortex nozzle 5 are respectively provided with a first vortex inlet 10, a second vortex inlet 11, and a third vortex inlet 12. The first vortex inlet 10, the second vortex inlet 11, and the third vortex inlet 12 are sealed to the circulating water inlet pipe 8, and the circulating water inlet pipe 8 is connected to the booster pump. In this embodiment, the pressure pump serves as the power source and has multiple functions: during the fertilizer dissolution stage, the pressure pump can pump external water or initial solution into the fertilizer dissolution tank 1 and drive the vortex nozzle to achieve circulating dissolution; during the fertilization stage, the pressure pump can pump the solution from the second chamber for fertilization and irrigation; in the capacity expansion and fertilizer transfer function, the pressure pump pumps the dissolved solution from the fertilizer dissolution tank into the fertilizer preparation tank, making it easier to expand the volume of the fertilizer dissolution tank or to store fertilizers with different functions simultaneously. The multi-purpose design of the pressure pump not only reduces the overall cost but also further improves the efficiency of use. The selection of the pressure pump in this embodiment needs to consider flow rate and pressure parameters to ensure that the vortex nozzle can generate sufficient flow velocity and coverage; the specific values ​​need to be adjusted according to the actual application scenario.

[0026] In this embodiment, the pneumatic jetting device 6 is installed at the center of the bottom of the fertilizer dissolving tank 1. It is preferably a microporous aerator head, whose structure includes multiple tiny air holes with diameters between 0.1 mm and 0.5 mm. When the air pump supplies air to the aerator head through the air inlet pipe 7, the gas is released from the micropores, forming a large number of fine bubbles. As these bubbles rise, they drive the surrounding liquid upwards, creating vertical stirring. Simultaneously, the bursting of the bubbles and their upward path generate turbulence, further promoting mixing.

[0027] In this embodiment, the power of the air pump is selected based on the depth of the fertilizer dissolving tank 1 and the required amount of bubbles.

[0028] In the embodiments, the air inlet pipe 7 is usually made of flexible hose, which is convenient for installation and maintenance. The power of the air pump is selected according to the depth of the fertilizer dissolving tank 1 and the required amount of bubbles.

[0029] In this embodiment, the heating device can be installed on the circulating water inlet pipe 8 or the air inlet pipe 7 to improve dissolution efficiency in low-temperature environments. The heating device is preferably an electric heating wire or a plate heat exchanger, which adjusts the water temperature or air temperature. Using a heating device enhances the adaptability of the device, enabling it to operate stably under various climatic conditions.

[0030] When using this device, fertilizer is added to the first chamber of the fertilizer dissolving tank 1 from the top. After being pressurized by the pressure pump, the water is sprayed into the first chamber of the fertilizer tank through the circulating water inlet pipe 8 to the first vortex nozzle 3, the second vortex nozzle 4, and the third vortex nozzle 5. The high-pressure water jet is sprayed out from the vortex nozzle at a tangential angle, impacting the tank wall to form a horizontal vortex, which drives the water in the entire tank to rotate. At the same time, high-pressure air provided by the air pump is sprayed out from the center of the bottom of the tank through the air inlet pipe 7 and the pneumatic jet device 6, which drives the water to roll from bottom to top, realizing horizontal and vertical stirring, which improves the fertilizer dissolving efficiency. The fertilizer solution obtained after dissolving will be stored in the second chamber through the filter screen 2 for subsequent use.
