Abstract
Description
Technical Field
[0001] This utility model relates to the field of nutrient solution preparation technology, and in particular to a nutrient solution preparation device. Background Technology
[0002] Nutrient solution preparation is of great importance in many fields such as agriculture, horticulture, and scientific research. For many crops and plants, nutrient solutions provide the various nutrients they need for growth, such as macroelements like nitrogen, phosphorus, and potassium, as well as microelements like iron, manganese, and zinc. Different plant species have strict requirements regarding the composition and concentration of nutrient solutions at different growth stages.
[0003] Currently, a common method of mixing is to directly add multiple raw materials to a mixing tank. However, this method can easily lead to insufficient contact and uniform dispersion between the raw materials, especially powdered materials. When multiple powdered raw materials enter the mixing tank simultaneously, due to significant differences in particle size, density, and flowability, stratification and clumping can easily occur, thus affecting the mixing effect and efficiency of the nutrient solution. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes a nutrient solution preparation device, which has the advantages of improving mixing effect and efficiency.
[0005] This utility model provides a nutrient solution preparation device, including a mixing tank. Multiple support rods are provided on the top of the mixing tank, and a top plate is provided on the top of the multiple support rods. A stirrer is provided inside the mixing tank. A discharge pipe is provided at the bottom of the mixing tank. A diversion box is provided at the bottom of the top plate. Multiple diversion pipes are provided on the side wall of the diversion box. A premixing pipe is connected to one end of each diversion pipe away from the diversion box, and the other end of the premixing pipe is connected to the mixing tank. A water inlet pipe is provided on the top of the diversion box, and a heating element is provided outside the water inlet pipe. A feeding assembly is provided on the diversion pipe.
[0006] By adopting the above technical solution, and by setting up a distribution box, distribution pipe, feeding assembly, and premixing pipe, multiple raw materials can be separately fed into the feeding hopper connected to the distribution pipe. During the water addition process, the water flow impacts the raw materials in the distribution pipe, and the water flow impacts the raw materials through the premixing pipe before being discharged into the mixing tank, achieving a preliminary premixing effect between the raw materials and water. This avoids problems such as uneven mixing and clumping that may occur when multiple raw materials are added to the mixing tank simultaneously, and improves the mixing efficiency and uniformity of the raw materials after entering the mixing tank.
[0007] Preferably, the heating element includes a heating cylinder, which is disposed on the top of the top plate. The end of the water inlet pipe away from the diversion box extends through the top plate and the heating cylinder to the outside. The interior of the heating cylinder is provided with electric heating wires that are distributed around the side wall of the water inlet pipe.
[0008] By employing the above technical solution, the water in the inlet pipe is heated by an electric heating wire inside the heating cylinder, providing a suitable water temperature for the raw material premixing process. At a suitable temperature, the contact and mixing of the raw materials and water will be more thorough, improving mixing efficiency.
[0009] Preferably, a temperature sensor is provided on the side wall of the shunt box, and the shunt box is a circular box.
[0010] Using the above technical solution, the temperature sensor can monitor the water temperature in the distribution box in real time to ensure that the water temperature meets the premixing requirements.
[0011] Preferably, the feeding assembly includes feeding hoppers, the number of which is the same as the number of diverter pipes, a feeding pipe is fixedly connected to the bottom of the feeding hopper, and the other end of the feeding pipe is fixedly connected to the diverter pipe through the top plate.
[0012] Preferably, a metering valve is provided on the diversion pipe, and the metering valve is located between the feed pipe and the diversion box.
[0013] Using the above technical solution, the metering valve on the diversion pipe can accurately control the amount of water flowing from the diversion pipe into the premixing pipe, ensuring accurate mixing ratio of each raw material with water during the premixing stage.
[0014] Preferably, the stirrer includes a drive motor, which is fixedly installed on the top of the mixing tank and located below the top plate. The output shaft of the drive motor is fixedly connected to a rotating shaft, the bottom of which extends movably through the mixing tank to the lower part of the mixing tank. Multiple stirring rods are provided on the side wall of the rotating shaft.
[0015] Preferably, the premixed tube comprises a plurality of spiral tubes connected in series, and the inner wall of the spiral tubes is fixedly connected with an intercepting plate near the tube opening.
[0016] By adopting the above technical solution, multiple spiral tubes connected in series serve as premixing tubes, which prolongs the flow path of raw materials and water in the premixing stage, increases the mixing time, and causes the mixture of raw materials and water to impact the interception plate, making the mixing more thorough.
[0017] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: by setting up a diversion box, a diversion pipe, a feeding component and a premixing pipe, multiple raw materials can be put into the feeding hopper connected to the diversion pipe respectively. During the water addition process, the water flow impacts the raw materials in the diversion pipe respectively. The water flow impacts the raw materials and then discharges them into the mixing tank through the premixing pipe, so that the raw materials and water are pre-mixed. This avoids the problems of uneven mixing and agglomeration that may occur when multiple raw materials are added to the mixing tank at the same time, and improves the mixing efficiency and uniformity of the raw materials after entering the mixing tank.

[0027] like Figure 1-4 As shown, the present invention proposes a nutrient solution preparation device, including a mixing tank 1, a plurality of support rods 3 on the top of the mixing tank 1, a top plate 4 on the top of the plurality of support rods 3, a stirrer 6 inside the mixing tank 1, a discharge pipe 2 at the bottom of the mixing tank 1, a diversion box 7 at the bottom of the top plate 4, a temperature sensor 10 on the side wall of the diversion box 7, the diversion box 7 being a circular box, a plurality of diversion pipes 11 on the side wall of the diversion box 7, a premixing pipe 13 connected to one end of the diversion pipe 11 away from the diversion box 7, the other end of the premixing pipe 13 connected to the mixing tank 1, a water inlet pipe 8 on the top of the diversion box 7, a heating element on the outside of the water inlet pipe 8, and a feeding assembly on the diversion pipe 11.
[0028] It should be noted that the temperature sensor 10 can monitor the water temperature in the diversion box 7 in real time to ensure that the water temperature meets the premixing requirements, and that water at a suitable temperature can increase the rate of raw material dissolution and improve mixing efficiency.
[0029] By adopting the above technical solution, and by setting up a distribution box 7, a distribution pipe 11, a feeding assembly, and a premixing pipe 13, multiple raw materials can be separately fed into the feeding hopper connected to the distribution pipe 11. During the water addition process, the water flow impacts the raw materials in the distribution pipe 11, and the water flow impacts the raw materials through the premixing pipe 13 before being discharged into the mixing tank 1, achieving a preliminary premixing effect between the raw materials and water. This can avoid problems such as uneven mixing and clumping that may occur when multiple raw materials are added to the mixing tank 1 at the same time, and improve the mixing efficiency and uniformity of the raw materials after entering the mixing tank 1.
[0030] Please see Figure 3 In this embodiment, the heating element includes a heating cylinder 9, which is disposed on the top of the top plate 4. The end of the water inlet pipe 8 away from the diversion box 7 extends through the top plate 4 and the heating cylinder 9 to the outside. The interior of the heating cylinder 9 is provided with electric heating wires 91 that are distributed around the side wall of the water inlet pipe 8.
[0031] The water in the inlet pipe 8 is heated by the electric heating wire 91 inside the heating cylinder 9, which provides a suitable water temperature for the raw material premixing process. At a suitable temperature, the contact and mixing between the raw materials and water will be more thorough, improving the mixing efficiency.
[0032] Please see Figure 1 , Figure 2 In this embodiment, the feeding assembly includes a feeding hopper 15, the number of feeding hoppers 15 is the same as the number of diversion pipes 11, the bottom of the feeding hopper 15 is fixedly connected to a feeding pipe 14, and the other end of the feeding pipe 14 is fixedly connected to the top plate 4 and the diversion pipe 11.
[0033] It is worth mentioning that the inner wall of the feed pipe 14 is coated with Teflon. Teflon is a material with an extremely low coefficient of friction, which can make the powder raw material slide more smoothly on the inner wall of the feed pipe.
[0034] Please see Figure 5 In this embodiment, the stirrer 6 includes a drive motor 61, which is fixedly installed on the top of the mixing tank 1 and located below the top plate 4. The output shaft of the drive motor 61 is fixedly connected to a rotating shaft 62. The bottom of the rotating shaft 62 extends through the mixing tank 1 to the lower part of the mixing tank 1. A plurality of stirring rods 63 are provided on the side wall of the rotating shaft 62.
[0035] In this embodiment, a metering valve 12 is provided on the diversion pipe 11, and the metering valve 12 is located between the feed pipe 14 and the diversion box 7.
[0036] The amount of water flowing from the diversion pipe 11 into the premixing pipe 13 can be precisely controlled by the metering valve 12 on the diversion pipe 11, ensuring accurate mixing ratio of each raw material with water during the premixing stage.
[0037] The mixing tank 1 is equipped with a control panel 5 on its side wall. The temperature sensor 10, electric heating wire 91, metering valve 12 and drive motor 61 are all electrically connected to the control panel 5.
[0038] Please see Figure 4 In this embodiment, the premixed tube 13 includes a plurality of spiral tubes 131 connected in series, and the inner wall of the spiral tube 131 is fixedly connected with an intercepting plate 132 near the tube opening.
[0039] It should be noted that the multiple spiral tubes 131 are connected by welding. The multiple spiral tubes 131 connected in series serve as premixing tubes 13, which prolongs the flow path of raw materials and water in the premixing stage and increases the mixing time. The mixture of raw materials and water impacts the intercepting plate 132, making the mixing more thorough.
[0040] Working Principle: Various powdered raw materials are separately fed into the feeding hopper 15 connected to the distribution pipe 11. The water inlet pipe 8 is connected to a water supply device (not shown). The electric heating wire 91 is activated via the control panel 5 to heat the water in the water inlet pipe 8 within the heating cylinder 9. The temperature sensor 10 monitors the water temperature in the distribution box 7 in real time and feeds the data back to the control panel 5. The control panel 5 precisely adjusts the heating power of the electric heating wire 91 according to the preset temperature value to ensure the water temperature reaches a suitable premixing temperature. The heated water enters the distribution box 7 from the water inlet pipe 8, and the water in the distribution box 7 flows into each distribution pipe 11. The water flow impacts the raw materials in the distribution pipes 11, carrying them into the premixing pipe 13. When the raw materials and water flow within the spiral tube 131, the flow path is extended due to the guiding effect of the spiral tube 131, increasing the mixing time. Simultaneously, the intercepting plates 132 on the inner wall of the spiral tube 131 block and divert the mixture of raw materials and water, making the mixing more thorough. The premixed mixture flows into the mixing tank 1, the drive motor 61 starts, and drives the rotating shaft 62 and the stirring rod 63 to rotate. The stirring rod 63 further mixes the premixed raw materials in the mixing tank 1 to ensure that the components of the nutrient solution are evenly dispersed, thus completing the final nutrient solution preparation.
[0041] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
