At present, the mixing device for water soluble fertilizer production in the existing technology mainly consists of a reaction tank and a stirring mechanism, which is arranged in the reaction tank and used for stirring and mixing solid-liquid mixed raw materials.
[0003] In the existing device, the solid raw materials are usually directly added to the liquid raw materials. This feeding method has obvious disadvantages. The solid raw materials are prone to accumulate at the bottom of the reaction tank and are difficult to mix with the liquid raw materials quickly due to the lack of dispersion measures, resulting in poor reaction effect, uneven fertilizer mixing and reduced product quality.
[0004] On the other hand, direct feeding also easily leads to mixing of liquid and solid raw materials in the channel during discharging, causing condensation and blocking the discharge pipe, affecting the continuity and stability of production, increasing maintenance cost and production interruption risk.
[0005] In summary, the existing mixing device for water soluble fertilizer production not only has slow reaction rate, but also is prone to condensation and blocking of the discharge pipe due to mixing of solid raw materials. Therefore, there is an urgent need for a new mixing device that can solve the above problems. SUMMARY

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0023] Please refer to Figure 1 The utility model relates to a kind of mixing device for water-soluble fertilizer production, its structure is similar to prior art device, mainly by reaction tank 2 and stirring mechanism 3 are composed.Stirring mechanism 3 is arranged in reaction tank 2, and its main function is to carry out sufficient stirring mixing to solid-liquid mixed raw materials.
[0024] It is worth noting that, as Figure 1 Indicated, the stirring mechanism 3 used in the device is a paddle stirring mechanism 3.In actual application, according to the viscosity of liquid raw materials, the rotating direction of the paddle can be adjusted to prevent solid raw materials from accumulating and depositing at the bottom of the reaction tank 2, thereby affecting the reaction effect.
[0025] Please refer to Figure 1 , Figure 2 Compared with prior art device, the device is innovatively provided with mounting groove on the upper end of the reaction tank 2, and the storage shell 1 is skillfully embedded in the mounting groove, which is specially used for loading solid raw materials.
[0026] Therefore, the device is provided with a feed inlet on the upper end of the storage shell 1 for adding raw materials required for fertilizer production into the storage shell 1.
[0027] Correspondingly, the device carefully arranges multiple discharge pipes 4 below the storage shell 1, which are closely connected with the storage shell 1 to ensure that the raw materials can be smoothly transported into the reaction tank 2.
[0028] It is worth noting that the multiple discharge pipes 4 are at the same level, which can avoid the reduction of the amount of liquid raw materials inside the reaction tank 2 caused by the inconsistent height of the multiple discharge pipes 4. In actual operation, the liquid raw materials should not be in contact with the discharge pipes 4 to prevent the solid raw materials from mixing and condensing with the liquid raw materials inside the discharge pipes 4, thereby blocking the discharge pipes 4.
[0029] It should be noted that the use of the paddle stirring mechanism 3 can also maximize the prevention of the occurrence of liquid raw material vortex, avoiding the actual stirring process where the liquid raw material rises vertically beyond the expected height.
[0030] Further, as shown in Figure 2 , Figure 3 , the device specifies that the projection of each discharge pipe 4 in the vertical plane is an L-shaped structure, including a horizontal section 403 and a vertical section 401.
[0031] Among them, the vertical section 401 is fixedly connected with the storage shell 1, and the angle between the horizontal section 403 and the horizontal plane is greater than zero degrees and less than 90 degrees. This unique structural design allows the raw materials to form a certain inclination angle when flowing out of the discharge pipe 4, thereby more evenly spreading into the reaction tank 2, significantly improving the mixing effect.
[0032] In addition, the device is specially designed to enable each vertical section 401 and the corresponding horizontal section 403 to be rotationally connected through a flexible connection section 402. At the same time, a driving mechanism 5 is arranged on the upper side of the multiple horizontal sections 403, which can drive the horizontal section 403 to rotate, thereby adjusting the direction and range of discharge, and thus more effectively improving the dispersion uniformity of the raw materials in the reaction tank 2.
[0033] It is worth noting that, as shown in Figure 2 , Figure 3 , the flexible connection section 402 adopted by the device is in the form of a bellows. In fact, the bellows are mostly made of plastic materials, which, with their unique structural characteristics, can not only be bent, but also effectively prevent excessive deformation during bending, thereby ensuring that the inner diameter of the flexible connection section 402 will not decrease when adjusting the inclination angle of the horizontal section 403.
[0034] Please refer to Figure 2 , Figure 3 , Figure 4 , specifically, the driving mechanism 5 includes a driving motor 501, which is located outside the reaction tank 2 and is fixedly connected thereto, and its output shaft extends into the reaction tank 2.
[0035] In addition, the output shaft of the driving motor 501 is provided with a key-connected wire roller 502.
[0036] Therefore, the device is provided with a driven plate 504 above the plurality of horizontal sections 403, the lower side of the driven plate 504 is rotatably connected with the plurality of discharge pipes 4, and the upper end of the driven plate 504 is fixedly connected with a pull rope 503, the pull rope 503 is wound on the outer side end of the wire roller 502 and is fixedly connected therewith, which makes the device control the rotation of the wire roller 502 through the driving motor 501 to change the inclination angle of the horizontal section 403.
[0037] It is worth noting that, as shown in Figure 3 , Figure 4 , Figure 5 The other end of the pull rope 503 needs to be folded back through the driven plate 504 in order to be fixedly connected with the wire roller 502, so as to allow the wire roller 502 and the driving motor 501 to be arranged below the material storage shell 1 (i.e. the discharge pipe 4), thereby further increasing the height of the discharge pipe 4 to avoid contact between the liquid raw material and the discharge pipe 4.
[0038] It should be noted that, in actual operation, when the driving motor 501 is started, the output shaft drives the wire roller 502 to rotate. When the wire roller 502 rotates, the pull rope 503 wound thereon will be pulled or loosened. When the pull rope 503 is pulled, the driven plate 504 rises, and since it is rotatably connected with the horizontal sections 403 of the plurality of discharge pipes 4, it can drive these horizontal sections 403 to rotate around the flexible connecting section 402; when the pull rope 503 is loosened, the horizontal sections 403 of the discharge pipe 4 return to the initial position under the action of gravity (combined with the gravity of the solid raw material in the inner cavity thereof). By controlling the forward and reverse rotation and rotation time of the driving motor 501, the reciprocating rotation of the horizontal sections 403 of the discharge pipe 4 can be realized, thereby adjusting the direction and range of discharging.
[0039] Further, the driven plate 504 is provided with a through hole 505, an upper and lower axial limiting tube 6 is inserted into the through hole 505, and the limiting tube 6 is fixedly connected with the material storage shell 1. The limiting tube 6 is responsible for limiting the up and down movement range of the driven plate 504 and providing guidance, ensuring that the driven plate 504 is stable without shaking or deviation when moving, thereby ensuring that the driving mechanism 5 can accurately drive the horizontal sections 403 of the discharge pipe 4 to rotate.
[0040] It is worth noting that the other end of the pull rope 503 passes through the limiting tube 6 and is firmly connected with the wire roller 502, and the internal space of the limiting tube 6 serves as the activity channel of the pull rope 503.
[0041] Further, as shown in Figure 3 ,Figure 5 As shown, the device restricts multiple driven pipes to be dispersedly arranged under the corresponding storage shell 1, which makes the solid raw materials be added to different positions of the liquid raw materials, avoids the solid raw materials to be enriched in a single rotating level of the liquid raw materials (the positions with the same distance from the central axis of the reaction tank 2 in the cavity of the reaction tank 2 are the same rotating level), thereby improving the contact area of the liquid raw materials and the solid raw materials and increasing the dispersion range of the solid raw materials.
[0042] Further, the multiple driven pipes under the lower side of the single storage shell 1 are restricted to be directed to different directions, i.e., the multiple horizontal sections 403 are directed to different directions, which utilizes the inclined structure of the horizontal sections 403 to further increase the range of the liquid raw materials covered by the single storage shell 1, thereby further expanding the dispersion range of the solid raw materials.
[0043] Further, in order to facilitate use, conform to the actual use habit (in practice, the feed inlet of the storage shell 1 is generally provided with a rectangular structure, which can facilitate cooperation with other material lifting mechanisms, such as an auger and a cylinder type elevator), avoid the solid raw materials to be accumulated at a specific position of the storage shell 1, the device restricts the number of the storage shells 1 to be multiple, and the multiple storage shells 1 are arranged at equal distances around the central axis of the reaction tank 2.
[0044] Meanwhile, the multiple storage shells 1 also make the device in practice be able to add multiple solid raw materials according to habit, thereby saving the mixing step of the solid raw materials in the early stage.
[0045] Correspondingly, the lower side of each storage shell 1 is provided with a driving mechanism 5. The design allows the driving mechanism 5 under each storage shell 1 to independently control the discharging direction and range of the discharging pipe 4, thereby ensuring that different raw materials can be more uniformly mixed, and further improving the production quality and efficiency of the water-soluble fertilizer.
[0046] In the actual application process of the device:
[0047] I. Preparation stage
[0048] 1. Raw material preparation
[0049] Prepare the solid raw materials and liquid raw materials necessary for producing the water-soluble fertilizer. The solid raw materials include various mineral salts and trace elements, and the liquid raw materials include water and nutrient solution.
[0050] Strictly check the quality and quantity of the raw materials to ensure that they meet the production standards.
[0051] 2. Equipment inspection
[0052] The core equipment components such as the reaction tank 2, the stirring mechanism 3, the storage shell 1, the discharging pipe 4 and the driving mechanism 5 need to be functionally detected to ensure that they operate correctly and no damage or blockage occurs.
[0053] Check the smoothness of the feed inlet, discharge pipe 4 and other passages to ensure the smoothness of the raw material conveying process.
[0054] II. Feeding stage
[0055] 1. Solid raw material feeding
[0056] Solid raw materials are added to the storage shell 1 through the feed inlet at the upper end of the storage shell 1. Due to the multiple quantity characteristics of the storage shell 1, different types of solid raw materials can be added to the corresponding storage shell 1 according to the formula requirements.
[0057] The discharge pipe 4 below each storage shell 1 is responsible for conveying the solid raw materials to the reaction tank 2. The horizontal section 403 of the discharge pipe 4 has an angle with the horizontal plane between 0° and 90°, which ensures that the solid raw materials can be uniformly spread to the reaction tank 2 at a specific inclination angle.
[0058] After starting the driving mechanism 5, the motor-driven wire roller 502 starts to rotate, pulling the driven plate 504, which drives the horizontal section 403 of the discharge pipe 4 to rotate flexibly around the flexible connection section 402, thereby accurately adjusting the discharge direction and range of the solid raw materials, further improving the dispersion uniformity of the solid raw materials in the reaction tank 2.
[0059] 2. Liquid raw material feeding
[0060] Liquid raw materials are injected into the reaction tank 2 through a specific liquid feeding channel (although not detailed in the manuscript, but should be considered in actual production). The timing of adding liquid raw materials can be based on the requirements of the production process, at the same time or after the addition of solid raw materials.
[0061] III. Mixing stage
[0062] 1. Start the stirring mechanism 3
[0063] After the solid raw materials and liquid raw materials are added to the reaction tank 2, the internal stirring mechanism 3 is started. The stirring mechanism 3 then mixes and stirs the solid raw materials and liquid raw materials in the tank.
[0064] During the stirring process, the discharge pipe 4 continuously adjusts the discharge position and range of the solid raw materials, promoting effective contact and mixing of the solid raw materials and liquid raw materials.
[0065] 2. Continuous stirring
[0066] The stirring mechanism 3 needs to continue to run to the specified time, during which the stirring time and speed are accurately controlled according to the specific fertilizer formula and production requirements, to ensure that the solid raw materials can be completely dissolved in the liquid raw materials, achieving uniform mixing effect.
[0067] IV. Discharge stage
[0068] 1. Mixing completion inspection
[0069] After the stirring time reaches the predetermined value, the mixing state of the fertilizer in the reaction tank 2 is inspected to ensure that the solid raw materials and the liquid raw materials are uniformly mixed, and the quality of the fertilizer meets the production standard.
[0070] 2. Discharging
[0071] The discharge port of the reaction tank 2 is opened, and the uniformly mixed water-soluble fertilizer is transported to the subsequent packaging or storage process.
[0072] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
