Technical Field
[0001] This utility model relates to the field of water-soluble fertilizer technology, specifically to a stirring device for preventing crystallization of water-soluble fertilizer anti-caking agents. Background Technology
[0002] Water-soluble fertilizers are compound fertilizers that can be completely dissolved in water. They have advantages such as improving fertilizer utilization and saving energy and protecting the environment. However, during storage and transportation, water-soluble fertilizers are prone to gradually losing fluidity and sticking together to form hard lumps, which affects product quality. Therefore, anti-caking agents need to be added during the processing of water-soluble fertilizers to prevent crystallization.
[0003] Traditional water-soluble fertilizer mixing devices mostly adopt a single-layer mixing structure, which can only stir the material in one direction and is difficult to achieve multi-angle mixing. This leads to local caking and uneven mixing of the material during the mixing process. The bottom material often settles due to insufficient mixing, which affects the mixing effect of the anti-caking agent. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-7 This utility model provides a technical solution: a water-soluble fertilizer anti-caking agent anti-crystallization stirring device, including a shell 1, a shell cover 2, a feed pipe 3, a discharge pipe 4, a steam inlet pipe 5, a steam outlet pipe 6, a support ring 7, a driven rod 8, an upper stirring plate 9, a lower stirring rod 10, a motor 11, a drive rod 12, a sieve plate 13, a mounting ring 14, a telescopic rod 15, a spring 16, a cylinder 17, and a push plate 18.
[0032] The outer shell 1 is a hollow double-layer structure. A shell cover 2 is bolted to the top of the outer shell 1. An inlet pipe 3 penetrates the surface of the shell cover 2, and an outlet pipe 4 penetrates the lower surface of the outer shell 1. Valves are installed inside the inlet pipe 3 and the outlet pipe 4. A steam inlet pipe 5 penetrates the side surface of the outer shell 1, and a steam outlet pipe 6 penetrates the other side surface of the outer shell 1. The steam inlet pipe 5 and the steam outlet pipe 6 are respectively inserted into the interlayer of the outer shell 1. A multi-layer stirring structure is installed inside the outer shell 1. This multi-layer stirring structure achieves material mixing through a support ring 7 and a driven rod 8. The multi-layer stirring structure includes the support ring 7, which is a hollow circular structure. The support ring 7 is rotatably mounted on the inner wall of the outer shell 1. A support rod is installed on the lower surface of the support ring 7 to support... The other end of the support rod on the lower surface of ring 7 is fixedly connected to the outer surface of driven rod 8. The upper end of driven rod 8 is provided with a groove, and the inner wall of the groove at the upper end of driven rod 8 is provided with a cross-shaped protrusion. An upper stirring plate 9 is fixed on the outer surface of driven rod 8. The upper stirring plate 9 is inclined and has 6 rings. A lower stirring rod 10 is provided below the upper stirring plate 9. The lower stirring rod 10 is inclinedly fixed on the outer surface of driven rod 8 and is arranged in a ring-shaped staggered manner on the outer surface of driven rod 8. A motor 11 is fixedly installed on the upper surface of shell cover 2. The output end of motor 11 passes through the upper surface of shell cover 2 and is connected to drive rod 12. A cross-shaped slot is provided at the lower end of drive rod 12. The cross-shaped slot on the lower surface of drive rod 12 engages and matches with the upper end of driven rod 8.
[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, before using this device, the outer shell 1 and the cover 2 are first installed and connected. The cover 2, along with the motor 11 and the drive rod 12, is inserted downwards into the interior of the outer shell 1, so that the drive rod 12 passes through the cylinder 17 on the surface of the sieve plate 13, and the cross-shaped groove at the lower end of the drive rod 12 engages with the upper end of the driven rod 8. The cover 2 is then connected to the outer shell 1 with bolts. The steam inlet pipe 5 and the steam outlet pipe 6 are connected to the steam system, allowing steam to enter the interlayer of the outer shell 1 from the steam inlet pipe 5 to heat the outer shell 1 and improve the reaction efficiency. After the outer shell 1 and the cover 2 are installed, the outer surface of the drive rod 12... The push rod on the lower surface of the push plate 18 is aligned with the trapezoidal protrusion of the cylinder 17. The valve of the feed pipe 3 is opened, and the water-soluble fertilizer anti-caking agent raw material is fed through the cross-shaped groove at the lower end of the drive rod 12 and the cross-shaped protrusion at the upper end of the driven rod 8. The driven rod 8 is driven to rotate synchronously. The driven rod 8 drives the upper stirring plate 9 and the lower stirring rod 10 to rotate. When the upper stirring plate 9 rotates, it lifts the material upward and gathers it towards the center, forming a vortex-like tumbling. When the lower stirring rod 10, which is distributed in a ring, rotates, it shears and stirs the bottom of the material to avoid bottom sedimentation and increase the reaction efficiency of the material. The material after the reaction is completed is discharged from the discharge pipe 4.
[0034] The interior of the outer casing 1 is equipped with a material screening structure. This structure uses a screen plate 13 to initially screen and disperse the raw materials. The screening structure includes the screen plate 13, which is concave. A mounting ring 14, a hollow circular structure, is located below the screen plate 13 and is fixedly installed on the inner wall of the outer casing 1. A telescopic rod 15 is threaded through the surface of the screen plate 13 and rotatably connected to it. The lower end of the telescopic rod 15 is threaded and threaded to the surface of the mounting ring 14. A spring 16 is provided on the outer surface of the drive rod 12. One end of the spring 16 is fixed to the surface of the telescopic rod 15, and the other end of the spring 16 is fixed to the lower surface of the screen plate 13. A cylinder 17 is provided through the center of the screen plate 13. The upper and lower surfaces of the cylinder 17 are connected. The cylinder 17 encloses the drive rod 12. A trapezoidal protrusion is provided in a ring on the upper surface of the cylinder 17. A push plate 18 is provided above the cylinder 17. A push rod is provided on the lower surface of the push plate 18 and is aligned with the protrusion on the upper surface of the cylinder 17. The push plate 18 is fixedly installed on the outer surface of the drive rod 12.
[0035] like Figure 3 , Figure 5 and Figure 6As shown, when the raw material enters the interior of the outer shell 1 from the feed pipe 3, it first falls onto the surface of the screen plate 13 and is dispersed by the screen plate 13. During this process, the motor 11 drives the drive rod 12 to rotate, and the drive rod 12 drives the push plate 18 to rotate. The rotating push plate 18 drives the push rod below to rotate. The push plate 18 presses down on the trapezoidal protrusion of the cylinder 17, causing the cylinder 17 to move downward. The cylinder 17 drives the screen plate 13 to move downward. The screen plate 13 compresses the telescopic rod 15 downward and compresses the spring 16. When the push plate 18 loses its force on the cylinder 17, the screen plate 13 moves upward under the action of the spring 16, thus realizing the up-and-down vibration process of the screen plate 13. The vibration of the screen plate 13 improves the screening efficiency of the material. The raw material falls into the lower part of the outer shell 1 through the screen holes, and larger lumps remain on the screen plate 13 and continue to be dispersed by vibration, thereby increasing the mixing efficiency of the subsequent materials.
[0036] Working principle: When using this water-soluble fertilizer anti-caking agent anti-crystallization stirring device, connect the shell cover 2 to the outer shell 1 so that the cross-shaped groove at the lower end of the drive rod 12 engages with the cross-shaped protrusion at the upper end of the driven rod 8. Connect the steam inlet pipe 5 and the steam outlet pipe 6 to the steam system. Steam enters the jacket of the outer shell 1 from the steam inlet pipe 5 for heating. The raw material enters from the feed pipe 3 and falls downward onto the surface of the sieve plate 13. Start the motor 11, which drives the drive rod 12 to rotate. The drive rod 12 drives the push plate 18 to rotate. The push rod on the lower surface of the push plate 18 presses the trapezoidal protrusion on the cylinder 17, causing the cylinder 17 to drive the sieve plate 13 to move downward. With the help of the spring 16, the sieve plate 13 vibrates, which screens and disperses the raw material. At the same time, the drive rod 12 drives the driven rod 8 to rotate, which drives the upper stirring plate 9 and the lower stirring rod 10 to rotate, so that the material is mixed evenly. After the reaction is completed, it is discharged from the outlet pipe 4, which increases the overall practicality.
