Description

A fertilizer production formulation and mixing device and method Technical Field

[0001] This invention belongs to the field of fertilizer production technology, and particularly relates to a mixing and blending device and method for fertilizer production. Background Technology

[0002] In fertilizer production, blending is a core element in improving fertilizer efficiency and meeting the diversified needs of agricultural production. Its necessity is mainly reflected in the following aspects: First, it balances nutrient supply and adapts to crop needs. Single fertilizers contain only one or a few nutrients, which cannot meet the nutritional needs of crops throughout their entire growth period. Through blending, macronutrients such as nitrogen, phosphorus, and potassium can be scientifically proportioned with micronutrients such as calcium, magnesium, and zinc. At the same time, organic components such as humic acid and amino acids are added to construct a comprehensive and balanced nutrient system, accurately matching the nutrient preferences of different crops at different growth stages, and avoiding nutrient deficiency or excess problems in crops.

[0003] Secondly, optimizing fertilizer characteristics and improving application efficiency: Different fertilizers have different physicochemical properties. Blending can improve fertilizer caking resistance, hygroscopicity, and particle uniformity, facilitating mechanized application and reducing waste. In addition, by adding slow-release agents, stabilizers, and other components, the nutrient release rate can be regulated, synchronizing nutrient supply with crop absorption, reducing nutrient volatilization and leaching losses, improving fertilizer utilization, and achieving cost savings and efficiency gains.

[0004] In the core process of fertilizer production, a mixing device is used. However, existing mixing devices generally have difficulty in effectively dealing with fertilizer clumping and material sticking to the walls during actual operation. This not only reduces the uniformity of fertilizer mixing, but also has an adverse impact on subsequent production processes. Summary of the Invention

[0013] A method for proportioning and mixing fertilizers, using any one of the fertilizer proportioning and mixing devices described in the previous step, includes: Step S1, where an operator pours the main raw materials (such as nitrogen, phosphorus, and potassium granules or powders) into a large feed box and pours trace additives (micronutrients, microbial agents, regulators, etc.) into a small feed box; Step S2, after the raw materials are poured in, weighing sensors installed at the connection between the small feed box and the mixing box, and at the large feed box, respectively, weigh the raw materials in the boxes and record the initial weight; Step S3, after weighing, the mixing processing component mixes the main raw materials in the large feed box and the small feed box...

The raw materials enter the mixing box, where the mixing processing component breaks up any clumps of raw materials. During the mixing process, a vibrating component assists to prevent the raw materials from sticking to the walls. The mixed raw materials are then discharged from the discharge port.

[0017] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0018] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] Please refer to Figures 1 to 7. An embodiment of the present invention provides a fertilizer production mixing and proportioning device, comprising: a frame 1; a mixing box 2, which is fixedly connected to the upper side of the frame 1, and a discharge port 3 is installed on the side wall of the mixing box 2; a large feed box 4, which is located on one side of the mixing box 2; a small feed box 5 is installed on one side of the large feed box 4, and both the large feed box 4 and the small feed box 5 are connected to the mixing box 2; a mixing and processing component, which is installed inside the mixing box 2 and is used to treat fertilizer agglomeration and material adhesion to the wall; and a vibrating component, which is installed at the bottom of the mixing box 2.

[0020] Using the above scheme: During use, weighing sensors are installed at the connection between the small feed box 5 and the mixing box 2, as well as at the large feed box 4. When performing fertilizer mixing operations, the staff pours the main raw materials, such as nitrogen, phosphorus, and potassium granules or powders, into the large feed box 4, and the trace elements, microbial agents, regulators, etc., in the trace additives into the small feed box 5. After pouring, the weighing sensors weigh the raw materials in the box and record the weight. Then, the mixing processing component transports the raw materials to the mixing box 2. At this time, the weight of the large feed box 4 and the small feed box 5 decreases. By comparing the weight with that before transport, the proportion of raw materials entering the mixing box 2 is detected to complete the mixing. When the raw materials enter the mixing box 2, the mixing processing component breaks up the clumps of raw materials and mixes them after they enter. During the mixing process, the vibrating component works in conjunction to prevent the raw materials from sticking to the wall. After the mixing is completed, the raw materials are discharged from the discharge port 3.

[0021] Furthermore, the mixing and processing assembly includes: a rubber layer 6 fixedly connected to the inner wall of the mixing box 2; the rubber layer 6 corresponds to the internal shape of the mixing box 2, the rubber layer 6 is located in the lower half of the mixing box 2, the top side wall of the mixing box 2 is connected to a connecting box 7, and the large feed box 4 is installed on the top of the connecting box 7 and connected to the connecting box 7.

[0022] Furthermore, a first rotating shaft 8 is rotatably connected inside the large feed box 4, and a spiral blade 9 for conveying material is fixedly connected to the first rotating shaft 8. A first motor 10 is installed on the top of the large feed box 4. One end of the first rotating shaft 8 is fixedly connected to the output end of the first motor 10. Two symmetrically arranged second rotating shafts 11 are rotatably connected inside the connecting box 7. One end of each of the second rotating shafts 11 is equipped with a meshing gear 12, and a dispersing roller 13 for breaking up agglomerated materials is fixedly connected to each of the second rotating shafts 11.

[0023] Furthermore, a third rotating shaft 14 is rotatably connected inside the mixing box 2, and a spiral stirring frame 15 is fixedly connected to the third rotating shaft 14.

[0024] Furthermore, the frame 1 is equipped with a drive motor 16, and one end of the third rotating shaft 14 is fixedly connected to the output end of the drive motor 16. The output end of the drive motor 16 is connected to one of the second rotating shafts 11 via a transmission component 17.

[0025] Using the above scheme: During the raw material conveying stage, the weighing sensor between the large feed box 4 and the connecting box 7 monitors the raw material. The first motor 10 drives the first rotating shaft 8 and the spiral blade 9 to rotate. When the spiral blade 9 rotates, it conveys the raw material to the connecting box 7 and initially breaks up the clumps of raw material. After the raw material enters the connecting box 7, the drive motor 16 drives a second rotating shaft 11 to rotate through the transmission component 17. Through the cooperation of two gears 12, the other second rotating shaft 11 rotates synchronously. The two second rotating shafts 11 drive the dispersing roller 13 to rotate, and then disperse the raw material a second time. The raw material after the second dispersal enters the mixing box 2 and the rubber layer 6. The drive motor 16 drives the third rotating shaft 14 to rotate. The third rotating shaft 14 drives the spiral stirring frame 15 to rotate, and then stirs and mixes the raw material.

[0026] It should be noted that: First, the spiral blades 9 can also be installed in the small feed box 5, and the specific installation can be adjusted according to actual needs. Second, the transmission component 17 is a belt drive mechanism.

[0027] Furthermore, the vibrating assembly includes: a plurality of first fixing frames 18 fixedly connected to the spiral mixing frame 15; a turning plate 19 is fixedly connected to the first fixing frame 18, and an elastic scraper 20 that is in contact with the inner wall of the mixing box 2 and the rubber layer 6 is fixedly connected to the top of the turning plate 19.

[0028] Furthermore, multiple sets of elastic elements are installed in the interlayer 22 formed by the rubber layer 6 and the mixing box 2, and the multiple sets of elastic elements are arranged in a semi-circular shape.

[0029] Furthermore, the elastic element includes: a plurality of telescopic rods 21 arranged longitudinally in the interlayer 22; the fixed end of the telescopic rod 21 is fixedly connected to the mixing box 2; a support plate 23 is fixedly connected to the side of the rubber layer 6 near the protruding end of the telescopic rod 21; the protruding end of the telescopic rod 21 is fixedly connected to the support plate 23; a spring 24 is sleeved on the outside of each telescopic rod 21; and the two ends of the spring 24 are respectively fixedly connected to the support plate 23 and the mixing box 2.

[0030] Using the above scheme: In use, after the raw materials enter the mixing box 2, they accumulate on the rubber layer 6. Their gravity causes the rubber layer 6 to deform, pushing the support plate 23 to compress the telescopic rod 21 and the spring 24 (the greater the weight of the raw materials, the greater the compression of the spring 24, until the elastic limit). When the drive motor 16 drives the third rotating shaft 14 and the spiral stirring frame 15 on it to rotate, it will drive the first fixed frame 18, the tipping plate 19 and the elastic scraper 20 to rotate. The elastic scraper 20 scrapes off the raw materials attached to the mixing box 2 and the rubber layer 6, and the tipping plate 19 stirs, scatters and convects the raw materials. When the spring 24 experiences a change in force, the tipping plate 19 throws up the material, and some of the material detaches from the rubber layer 6. The pressure on the rubber layer 6 decreases, and the compression decreases. The spring 24 pushes the telescopic rod 21, causing the support plate 23 to rebound instantaneously. The material falls and impacts the bottom of the box, and the spring 24 is additionally compressed, increasing the compression. During this process, the jumping of the spring 24 and the rubber layer 6 throws the bottom material up and scatters it to the upper layer, breaking the stratification, improving the mixing uniformity, and achieving micro-fluidization. For fertilizer powder that is easy to adhere, the jumping bottom can destroy the adhesion force and prevent the material from accumulating in the dead corner at the bottom.

[0031] It should be noted that a protective layer is provided on the side of the rubber layer 6 that contacts the elastic scraper 20.

[0032] A method for proportioning and mixing fertilizers, using any one of the fertilizer production proportioning and mixing devices described in the previous step, includes: Step S1, where an operator pours the main raw materials, such as nitrogen, phosphorus, and potassium granules or powders, into a large feed box 4, and pours trace elements, microbial agents, regulators, etc., from the micro-additives into a small feed box 5; Step S2, after the raw materials are poured in, weighing sensors installed at the connection between the small feed box 5 and the mixing box 2, and at the large feed box 4, respectively, weigh the raw materials in the boxes and record the initial weight; Step S3, after weighing, a mixing processing component mixes the main raw materials in the large feed box 4 and the raw materials in the small feed box 5... The trace additives are transported to the mixing tank 2; in step S4, during the raw material transportation process, the weight of the large feed tank 4 and the small feed tank 5 gradually decreases, and the weighing sensor compares the real-time weight with the initial weight before transportation to detect the weight of the raw materials entering the mixing tank 2, thereby completing the fertilizer ratio; in step S5, when the raw materials enter the mixing tank 2, the mixing processing component breaks up the clumps of raw materials; in step S6, after all the raw materials have entered the mixing tank 2, the mixing processing component stirs and mixes the raw materials; in step S7, during the mixing process, the vibrating component works in conjunction with the material vibrating component to prevent the raw materials from adhering to the inner wall of the tank.

[0033] The working principle of this invention is as follows: Weighing sensors are installed at the connection between the small feed box 5 and the mixing box 2, as well as at the large feed box 4. During fertilizer mixing, the worker pours the main raw materials, such as nitrogen, phosphorus, and potassium granules or powders, into the large feed box 4, and the trace elements, microbial agents, and regulators in the trace additives into the small feed box 5. After pouring, the weighing sensors weigh the raw materials in the box and record the weight. During the raw material conveying stage, the weighing sensors between the large feed box 4 and the connecting box 7 monitor the raw materials. The first motor 10 drives the first rotating shaft 8 and the spiral blade 9 to rotate. When the spiral blade 9 rotates, it conveys the raw materials to the connecting box 7. In box 7, the weight of the large feed box 4 and the small feed box 5 decreases. By comparing the weight with that before conveying, the proportion of raw materials entering the mixing box 2 is detected to complete the mixing. At the same time, the clumps of raw materials are initially broken up. After the raw materials enter the connecting box 7, the drive motor 16 drives a second rotating shaft 11 to rotate through the transmission component 17. Through the cooperation of two gears 12, the other second rotating shaft 11 rotates synchronously. The two second rotating shafts 11 drive the dispersing roller 13 to rotate, further dispersing the raw materials. The raw materials after secondary dispersal enter the mixing box 2 and the rubber layer 6. After entering the mixing box 2, the raw materials accumulate on the rubber layer 6, and their weight... The force causes the rubber layer 6 to deform, pushing the support plate 23 to compress the telescopic rod 21 and spring 24 (the greater the weight of the raw material, the greater the compression of the spring 24, until the elastic limit). The drive motor 16 drives the third rotating shaft 14 to rotate, and the third rotating shaft 14 drives the spiral mixing frame 15 to rotate, mixing the raw materials. When the drive motor 16 drives the third rotating shaft 14 and the spiral mixing frame 15 to rotate, it will drive the first fixed frame 18, the tilting plate 19 and the elastic scraper 20 to rotate. The elastic scraper 20 scrapes off the raw materials attached to the mixing box 2 and the rubber layer 6. The tilting plate 19 stirs, scatters and convects the raw materials. As the spring 24 changes force, the tipping plate 19 throws up the material, and some of the material detaches from the rubber layer 6. The pressure on the rubber layer 6 decreases, and the compression decreases. The spring 24 pushes the telescopic rod 21, causing the support plate 23 to rebound instantaneously. The material falls and impacts the bottom of the box, and the spring 24 is additionally compressed, increasing the compression. During this process, the jumping of the spring 24 and the rubber layer 6 throws the raw material at the bottom up and scatters it to the upper layer, breaking the stratification, improving the mixing uniformity, and realizing micro-fluidization. For fertilizer powder that is easy to adhere, the jumping bottom can destroy the adhesion force and prevent the raw material from accumulating in the dead corner at the bottom. The mixed raw material is discharged from the discharge port 3.
