[0002] Superphosphate, also known as ordinary superphosphate, is an important phosphate fertilizer. It belongs to water-soluble and quick-acting phosphate fertilizers. Its appearance is gray or off-white powder or granules. It is mainly used for topdressing, basal dressing or seed dressing of crops, supplying plants with elements such as phosphorus, calcium, and sulfur, and has the effect of improving alkaline soil. It can also be used as an ingredient for compound fertilizers. When mixed with nitrogen fertilizers, it has a nitrogen fixation effect and reduces nitrogen loss.

[0003] In the prior art, for example, Chinese patent CN215667156U discloses a device for producing superphosphate by modifying raffinate acid, including a mounting plate.

The surface of the mixing tank is communicated with a spraying pipe.

[0004] However, in the prior art, superphosphate has relatively high requirements for the size of phosphate rock during the production process. Some existing superphosphate production devices do not screen the phosphate rock and cannot classify and collect larger and smaller materials. There is a phenomenon that large-particle phosphate rock may not react fully, while small-particle phosphate rock may consume sulfuric acid too quickly, which makes it difficult to control the reaction conditions, thus affecting the final quality and output of the product. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that superphosphate has relatively high requirements for the size of phosphate rock during the production process. Some existing superphosphate production devices do not screen the phosphate rock and cannot classify and collect larger and smaller materials. There is a phenomenon that large-particle phosphate rock may not react fully, while small-particle phosphate rock may consume sulfuric acid too quickly, which makes it difficult to control the reaction conditions, thus affecting the final quality and output of the product. A superphosphate production device is proposed.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A superphosphate production device, comprising a box body, a fine division layer and a screening layer.

[0021] To better understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1-4 shown, the present utility model provides a calcium superphosphate production device, which includes a box body 1, a fine division layer 11, and a screening layer 12. The fine division layer 11 and the screening layer 12 are respectively located in the middle and above the middle of the box body 1. A fine screening mesh 13 is fixedly installed at the bottom of the fine division layer 11, and a primary screening mesh 14 is fixedly installed at the bottom of the screening layer 12. A driving motor 15 is fixedly installed in the middle of the upper end of the box body 1. The output end of the driving motor 15 penetrates through the middle of the primary screening mesh 14 and is rotatably connected to the fine screening mesh 13 at one end. A separation plate 16 is fixedly installed on one side of the output end of the driving motor 15 in the fine division layer 11, and a scraper 17 is fixedly installed on one side of the output end of the driving motor 15 in the fine division layer 11. A sensor 18 is fixedly installed on one side of the inner wall of the fine division layer 11. A chute 21 is opened on one side of the upper end of the box body 1, and a baffle 22 is slidably clamped in the middle of the chute 21. A hydraulic rod 19 is fixedly installed at the upper end of the box body 1, and the output end of the hydraulic rod 19 is fixedly connected to the baffle 22. A controller 20 is fixedly installed on one side of the hydraulic rod 19.

[0024] The following specifically describes the specific settings and functions of this embodiment. By setting a double-layer screen mesh and a hydraulic rod 19 that can automatically adjust the baffle 22 through the controller 20, during use, the crushed phosphate rock will enter the screening layer 12 in batches through the feed inlet 2. The driving motor 15 will drive the separation plate 16 to rotate around the center, which can stir the phosphate rock inside. During the stirring process, the small and high-quality phosphate rock will fall through the primary screening mesh 14 into the lower fine division layer 11, and the larger phosphate rock that does not meet the reaction requirements will remain above the primary screening mesh 14. Each time the separation plate 16 rotates past the sensor 18, it will be recorded. After accumulating a certain number of times, the sensor 18 will send a corresponding electrical signal to the controller 20. The controller 20 controls the on-off of the solenoid valve through the output port to drive the hydraulic rod 19. The hydraulic rod 19 will drive the baffle 22 to move upward. Under the action of inertia, the larger phosphate rock will be discharged through the gap after the baffle 22 moves upward for secondary crushing and processing. By screening phosphate rock of similar sizes to control the reaction conditions and strictly limit the size of the phosphate rock, the final quality and output of the calcium superphosphate product can be improved.

[0025] Example 2, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, there is an electrical connection between the sensor 18 and the controller 20, and an electrical connection between the controller 20 and the hydraulic rod 19. On the other side of the upper end of the box body 1, a feed inlet 2 is provided. A reaction layer 25 is formed between the fine sieve mesh 13 and the bottom of the box body 1. A feed hopper 24 is fixedly installed at the lower end of the fine sieve mesh 13. An acid-resistant pipe 26 is fixedly installed on the outer side of the reaction layer 25. One side of the acid-resistant pipe 26 is uniformly connected with nozzles 27 in a penetrating manner. The nozzles 27 are uniformly distributed on the inner wall of the reaction layer 25. An AC motor 28 is fixedly installed at the lower end of the box body 1. The output end of the AC motor 28 is uniformly fixedly installed with stirring fan blades 29. The stirring fan blades 29 are located in the middle of the reaction layer 25. A rotating groove 23 is provided on the inner wall of the fine division layer 11. One end of the scraper 17 is rotatably clamped with the rotating groove 23. A discharge pipe 30 is fixedly installed on one side of the lower end of the box body 1.

[0026] The effect achieved by the entire example is that the fine sieve mesh 13 can enable the phosphate rock that meets the reaction generation conditions to orderly pass through the filter holes and fall into the lower reaction layer 25. When falling into the reaction layer 25, it will first pass through the feed hopper 24. The upper part of the feed hopper 24 is large and the lower part is small, which can control the landing point of the phosphate rock and prevent the phosphate rock from hitting the nozzles 27 during the falling process, thus playing a role in protecting the nozzles 27 installed on the inner wall of the reaction layer 25. The nozzles 27 can spray sulfuric acid to react with the phosphate rock. Driven by the AC motor 28, the stirring fan blades 29 can continuously rotate to make the reaction between the phosphate rock and sulfuric acid more sufficient. After the reaction, the superphosphate generated can be discharged through the discharge pipe 30, which is convenient for collection.

[0027] Usage method and working principle of the device: During use, the crushed phosphate ore enters the screening layer 12 in batches through the feed inlet 2. The driving motor 15 drives the separation plate 16 to rotate around the center, which can stir the phosphate ore inside. During the stirring process, the small and high-quality phosphate ore will fall through the primary screening mesh 14 into the lower fine screening layer 11 below, and the larger phosphate ore that does not meet the reaction conditions will remain above the primary screening mesh 14. Each time the separation plate 16 rotates past the sensor 18, it will be recorded. After accumulating a certain number of times, the sensor 18 will send a corresponding electrical signal to the controller 20. The controller 20 controls the on-off of the solenoid valve through the output port to drive the hydraulic rod 19. The hydraulic rod 19 drives the baffle 22 to move upward. Under the action of inertia, the larger phosphate ore will be discharged through the gap after the baffle 22 moves upward for secondary crushing and processing. The fine screening mesh 17 enables the phosphate ore that meets the reaction generation conditions to pass through the filter holes orderly and fall into the lower reaction layer 25 below. When falling into the reaction layer 25, it will first pass through the feeding hopper 24, and the feeding hopper 24 can control the landing point of the phosphate ore to prevent the phosphate ore from hitting the nozzle 27 during the falling process. The nozzle 27 can spray sulfuric acid to react with the phosphate ore. Driven by the AC motor 28, the stirring fan blades 29 can rotate continuously to make the reaction between the phosphate ore and sulfuric acid more sufficient. After the reaction, the produced superphosphate can be discharged through the discharge pipe 30 for convenient collection. By screening phosphate ore of similar sizes to control the reaction conditions and strictly limit the size of the phosphate ore, the final quality and output of the superphosphate product can be improved.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
