Description

Technical Field

[0001] The utility model relates to the technical field of phosphogypsum processing, in particular to phosphorus element recovery and reprocessing equipment. Background Art

[0002] Phosphogypsum is a solid waste generated during the wet-process phosphoric acid process, primarily composed of calcium sulfate dihydrate. In addition to calcium sulfate, phosphogypsum also contains incompletely decomposed phosphate rock, residual phosphoric acid, fluoride, acid-insoluble matter, and organic matter. To facilitate phosphorus recovery and reprocessing, the phosphogypsum must be crushed. A search revealed Chinese patent publication number CN217411048U, which discloses an environmentally friendly ore crusher. While this device incorporates a spray mechanism to reduce dust during use, the nozzle is internally located, limiting its spray range. During crushing, the resulting debris can easily damage the nozzle, making it difficult to inspect and maintain. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a phosphorus element recovery and reprocessing device, which solves the problems raised in the background technology.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A phosphorus recovery and reprocessing device includes a body, one end of which is equipped with a crushing motor, a pad is installed at the bottom end of the crushing motor and the end of the lower surface of the body close to the crushing motor, a crushing roller is installed inside the body at the output end of the crushing motor, and the crushing roller is provided with crushing teeth.

[0006] The machine body is provided with a feed port located above the crushing roller, and a discharge port located below the crushing roller. A panel is installed on the machine body at the discharge port, and two sets of spray pipes are installed above the panel at the discharge port of the machine body.

[0007] An opening is provided on the enclosure, a loader is set up at the opening of the enclosure, a conveyor belt is installed in the loader, and loading plates are evenly arranged on the conveyor belt.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a speed reducer is installed between the crushing motor and the crushing roller, and the crushing motor drives the crushing roller to rotate through the speed reducer.

[0010] The beneficial effects of adopting the above further scheme are:

[0011] The speed reducer smoothly converts the high-speed, low-torque power of the crushing motor into the low-speed, high-torque power required by the crushing rollers. This conversion helps reduce shock and vibration during the crushing process, ensuring stable and reliable operation of the equipment. The speed reducer protects the crushing motor from the high torque and impact loads of the crushing process, thereby extending the motor's service life. It also reduces damage to other equipment components and reduces maintenance costs.

[0012] Furthermore, the crushing teeth are hook-shaped, and the crushing teeth are evenly distributed on the crushing roller, and the crushing teeth on the two crushing rollers are staggered.

[0013] The beneficial effects of adopting the above further scheme are:

[0014] The hook-shaped teeth increase the contact area and gripping force between the teeth and the material, making the crushing process more efficient. The teeth grip the material more firmly, breaking it into smaller particles through shearing, squeezing, and tearing. The even distribution of the teeth ensures that the crushing rollers maintain a stable crushing effect throughout the entire operation, avoiding local overload or uneven crushing. The staggered placement of the teeth on the two crushing rollers ensures that the material is subjected to crushing forces from multiple directions as it passes through the crushing zone, resulting in a more uniform crushing effect. This design helps reduce large particles in the material and improve the quality of the crushed product.

[0015] Furthermore, the spray pipe is evenly distributed with spray heads, and the angle between the spray heads and the horizontal direction is forty-five degrees.

[0016] The beneficial effects of adopting the above further scheme are:

[0017] The uniform distribution of the nozzles on the spray pipe ensures that the spray mist evenly covers the entire crushing area. This even distribution helps reduce blind spots and improve spraying efficiency. The nozzles are designed at a 45-degree angle to the horizontal, allowing the spray mist to spread over a larger fan-shaped area, further expanding the spray coverage and ensuring effective coverage of every corner. The spray mist forms a moist barrier in the crushing area, helping to absorb and dissipate heat generated during the crushing process, reducing the temperature in the work area. It also effectively inhibits the spread of dust, moistening and settling dust particles, reducing pollution to the environment and operators. The 45-degree spray angle allows the water mist to better contact the dust, improving dust removal effectiveness. During the crushing process, phosphorus materials may generate splashes. If these splashes directly impact the nozzles, they may damage or clog them. By positioning the nozzles on the spray pipe at a 45-degree angle to the horizontal, the possibility of splashes directly impacting the nozzles is reduced, thus protecting them from damage.

[0018] Furthermore, two groups of spray pipes are symmetrically distributed on both sides of the opening of the enclosure, and a water pipe joint is provided at one end of the spray pipe located outside the machine body.

[0019] The beneficial effects of adopting the above further scheme are:

[0020] Two sets of spray pipes are symmetrically positioned on either side of the enclosure opening, ensuring that water mist covers the crushing area from both directions, improving spray efficiency and uniformity. This layout helps reduce blind spots in the spraying process, providing more comprehensive cooling and dust removal within the crushing area. A water pipe connector is located on one end of the spray pipe, located outside the machine body, facilitating maintenance and repair. Operators can easily access the connector for necessary inspections and replacements without disassembling excessive equipment components.

[0021] Furthermore, a hopper is provided at one end of the loader facing away from the enclosure, and the rear end of the loader is located in the hopper.

[0022] The beneficial effects of adopting the above further scheme are:

[0023] The hopper serves as the feed port for the loader, and its design allows for convenient loading of the phosphorus material. The loader's terminal is located within the hopper, ensuring that the material is smoothly carried by the conveyor belt and into the crushing area. This continuous, smooth loading process improves the overall loading efficiency of the equipment. The hopper's design helps minimize spillage and scattering during the loading process, thus reducing material waste. Furthermore, since the loader's terminal is located within the hopper, any material that is not immediately carried by the conveyor belt remains in the hopper, awaiting the next delivery, further minimizing material loss.

[0024] Furthermore, a feeding motor is installed at one end of the feeding machine close to the hopper, and the conveyor belt is driven by the feeding motor.

[0025] The beneficial effects of adopting the above further scheme are:

[0026] The feeding motor directly drives the conveyor belt, realizing the automatic feeding process of materials. This design reduces the need for manual operation, improves the degree of automation of the production line, and thus improves production efficiency.

[0027] Furthermore, connecting plates are provided on both sides of the machine body, and brackets are provided on the upper surface and the lower surface of the connecting plates. The loader is supported and mounted on both sides of the machine body through the brackets.

[0028] The beneficial effects of adopting the above further scheme are:

[0029] The connecting plate and bracket design allows the loader to be securely mounted on either side of the machine. This stable mounting prevents the loader from shaking or tilting during operation, ensuring stable and reliable loading. The modular design of the connecting plate and bracket makes installation and removal of the loader relatively simple and quick. When maintenance or replacement of the loader is required, it can be easily removed from the machine, reducing maintenance costs and time.

[0030] The utility model provides a phosphorus recovery and reprocessing device with the following beneficial effects:

[0031] The combined action of the crushing motor, speed reducer, and crushing rollers—particularly the evenly distributed hook-shaped crushing teeth on the crushing rollers—efficiently breaks phosphorus materials into smaller particles for easier handling and processing. The staggered distribution of the crushing teeth further enhances the crushing effect, ensuring uniform and thorough crushing.

[0032] The equipment features a shield beneath the crushing rollers, effectively blocking potential splashes during crushing and protecting operators. Furthermore, the spray pipe design not only expands the spray coverage area but also prevents direct impact of splashes on the nozzles by increasing the distance from the crushing rollers, further enhancing the equipment's safety and reliability.

[0033] The nozzles on the spray pipe are evenly distributed at a 45-degree angle, ensuring effective spraying while also achieving automated cooling and dust removal during the crushing process. The feeder motor drives the conveyor belt, achieving automatic loading, improving production efficiency and ease of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] See also Figures 1 to 3 As shown, the embodiment provided by the utility model:

[0043] Example 1

[0044] A phosphorus recovery and reprocessing device includes a body 3, one end of which is mounted a crushing motor 1. Pads 15 are mounted at the bottom end of the crushing motor 1 and at the lower surface of the body 3, near the crushing motor 1. A crushing roller 4 is mounted within the body 3 at the output end of the crushing motor 1. A reducer 2 is mounted between the crushing motor 1 and the crushing roller 4. The crushing motor 1 drives the crushing roller 4 to rotate via the reducer 2. The reducer 2 can smoothly convert the high-speed, low-torque power of the crushing motor 1 into the low-speed, high-torque power required by the crushing roller 4. This conversion helps reduce impact and vibration during the crushing process, ensuring the stability and reliability of the equipment's operation. Through the action of the reducer 2, the crushing motor 1 can avoid directly bearing the high torque and impact loads during the crushing process, thereby extending the motor's service life. At the same time, it also reduces damage to other parts of the equipment and reduces maintenance costs. The crushing roller 4 is provided with crushing teeth 9. The crushing teeth 9 are hook-shaped and evenly distributed on the crushing roller 4. The crushing teeth 9 on the two crushing rollers 4 are staggered. The hook-shaped crushing teeth 9 design increases the contact area and gripping force between the crushing teeth 9 and the material, making the crushing process more efficient. The crushing teeth 9 can grasp the material more firmly and crush the material into smaller particles through various methods such as shearing, squeezing and tearing. The uniform distribution of the crushing teeth 9 ensures that the crushing roller 4 can maintain a stable crushing effect throughout the entire working process, avoiding local overload or uneven crushing. The crushing teeth 9 on the two crushing rollers 4 are staggered, so that the material can receive crushing forces from multiple directions when passing through the crushing area, thereby achieving a more uniform crushing effect. This design helps to reduce large particles in the material and improve the quality of the crushed product.

[0045] Example 2

[0046] like Figures 1 to 3 As shown, the present invention proposes a phosphorus recovery and reprocessing device. Compared with the first embodiment, this embodiment further includes: a feed port is provided on the machine body 3 above the crushing roller 4, and a discharge port is provided on the machine body 3 below the crushing roller 4. A panel 17 is installed on the machine body 3 at the discharge port to block splashes generated during crushing. Two sets of spray pipes 8 are installed above the panel 17 at the discharge port of the machine body 3. By increasing the distance between the spray pipes 8 and the crushing roller 4, the spray coverage area of ​​the spray pipes 8 is increased, and splashes generated during crushing can be prevented from damaging the nozzle 16. The two sets of spray pipes 8 are symmetrically distributed on both sides of the opening of the panel 17. One end of the spray pipe 8 located outside the machine body 3 is provided with a water pipe connector 10. The two sets of spray pipes 8 are symmetrically distributed on both sides of the opening of the panel 17 to ensure that the spray mist covers the crushing area from two directions simultaneously, thereby improving the efficiency and uniformity of the spray. This layout helps to reduce spray blind spots and provide more comprehensive cooling and dust removal in the crushing area. The spray pipe 8, located outside the machine body 3, is equipped with a water pipe connector 10 at one end. This design facilitates maintenance and overhaul. Operators can easily access the water pipe connector 10 for necessary inspection and replacement without having to disassemble excessive equipment components. Spray nozzles 16 are evenly distributed along the spray pipe 8, each angled at 45 degrees to the horizontal. This uniform distribution of nozzles 16 across the spray pipe 8 ensures that the spray mist uniformly covers the entire crushing area. This uniform distribution helps reduce blind spots and improves spray efficiency. The 45-degree angle of the nozzles 16 to the horizontal allows the spray mist to spread over a larger fan-shaped area, further expanding the spray coverage and ensuring effective coverage of every corner. The spray mist forms a moist barrier in the crushing area, helping to absorb and dissipate heat generated during the crushing process, reducing the temperature in the work area. Furthermore, the spray mist effectively inhibits the spread of dust, moistening and settling dust particles, reducing pollution to the environment and operators. The 45-degree spray angle allows the water mist to better contact the dust, improving dust removal effectiveness. Furthermore, during the crushing process, phosphorus materials may generate splashes. If these splashes directly impact the nozzle 16, they may damage or clog it. By positioning the nozzle 16 on the spray pipe 8 at a 45-degree angle to the horizontal, the likelihood of splashes directly impacting the nozzle 16 is reduced, thereby protecting the nozzle 16 from damage.

[0047] Example 3

[0048] like Figures 1 to 3As shown, the present invention proposes a phosphorus recovery and reprocessing device. Compared with the first embodiment, this embodiment further includes: an opening is provided on the enclosure 17, a loader 6 is set up at the opening of the enclosure 17, connecting plates 11 are provided on both sides of the body 3, and brackets 12 are provided on the upper and lower surfaces of the connecting plates 11. The loader 6 is supported and set up on both sides of the body 3 by the brackets 12. Through the design of the connecting plates 11 and the brackets 12, the loader 6 can be firmly installed on both sides of the body 3. This stable installation method ensures that the loader 6 will not shake or tilt during operation, thereby ensuring the stability and reliability of the loading. The modular design of the connecting plates 11 and the brackets 12 makes the installation and disassembly of the loader 6 relatively simple and quick. When the loader 6 needs to be maintained or replaced, it can be easily removed from the body 3, reducing maintenance costs and time. A hopper 7 is provided at the end of the loader 6 facing away from the enclosure 17, and the end of the loader 6 is located in the hopper 7. The hopper 7 serves as the feed port of the loader 6, and its design allows phosphorus material to be easily poured into it. The fact that the end of the loader 6 is located in the hopper 7 ensures that the material can be smoothly carried away by the conveyor belt 14 and enter the crushing area. This continuous and smooth loading process improves the loading efficiency of the entire equipment. The design of the hopper 7 helps to reduce splashing and scattering of materials during the pouring process, thereby reducing material waste. At the same time, since the end of the loader 6 is located in the hopper 7, even if some materials are not immediately taken away by the conveyor belt 14, they will remain in the hopper 7 and wait for the next conveyance, further reducing material loss. A loading motor 13 is installed at the end of the loader 6 near the hopper 7, and the conveyor belt 14 is driven by the loading motor 13. The conveyor belt 14 is directly driven by the loading motor 13, realizing the automatic loading process of the materials. This design reduces the need for manual operation, improves the degree of automation of the production line, and thus improves production efficiency. A conveyor belt 14 is installed in the loader 6, and a loading plate 5 is evenly arranged on the conveyor belt 14.

[0049] Working principle:

[0050] By starting the crushing motor 1, a power source is generated. The crushing motor 1 transmits power to the crushing roller 4 through the reducer 2 to achieve speed adjustment and smooth power transmission. The crushing roller 4 starts to rotate under the drive of the motor, and the hook-shaped and evenly distributed crushing teeth 9 on it interlock with the crushing teeth 9 on the other crushing roller 4, shearing, squeezing and tearing the phosphorus material entering the crushing area, thereby achieving crushing.

[0051] During the crushing process, the nozzle 16 on the spray pipe 8 starts to spray water, forming water mist to cover the crushing area. The spraying water mist helps to reduce the heat and dust generated during the crushing process, maintain a suitable temperature in the working area, and reduce the pollution of dust to the environment and equipment. By adjusting the distance between the spray pipe 8 and the crushing roller 4, it is ensured that the spraying water mist can cover the entire crushing area, improve the cooling and dust removal effects, and the design of the enclosure 17 effectively blocks the splashes that may be generated during crushing, protecting the safety of the operator.
