Description

Technical Field

[0001] This utility model relates to the field of phosphogypsum production technology, specifically to a phosphogypsum pulverizing device. Background Technology

[0002] Phosphogypsum is a solid waste generated during the sulfuric acid decomposition of phosphate rock in the production of phosphoric acid, phosphate fertilizers, and other products by phosphate chemical enterprises. It has long been considered industrial waste. However, with increasing environmental awareness, the resource utilization of phosphogypsum is receiving more and more attention. Resource utilization of phosphogypsum can reduce land occupation from stockpiling, lower pollution levels to soil, water, and air. Furthermore, phosphogypsum is rich in elements such as calcium and sulfur; through comprehensive utilization, waste can be recycled, improving resource utilization efficiency. Before resource utilization, phosphogypsum needs to be crushed to a certain particle size using a crusher to broaden its applicability.

[0003] For example, Chinese utility model patent CN219836603U provides a phosphogypsum crushing device, including a housing, a crushing mechanism, a conveying mechanism, a discharge plate, and a crushing mechanism. The crushing mechanism compresses and crushes the phosphogypsum, while the crushing mechanism, located below the conveying mechanism, screens phosphogypsum of the appropriate size through a screening trough and further crushes the phosphogypsum to achieve a certain particle size.

[0004] However, existing phosphogypsum pulverizing equipment cannot automatically perform secondary pulverization of phosphogypsum with particle sizes that do not meet the standard through a single pulverizing mechanism. Most of them achieve this by setting up multi-stage pulverizing mechanisms, which increases the cost of the equipment and the energy demand, resulting in a decrease in production efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model proposes a phosphogypsum pulverizing device to solve the technical problems mentioned in the background art, that existing phosphogypsum pulverizing devices cannot automatically perform secondary pulverization of phosphogypsum with particle size that does not meet the standard through a single pulverizing mechanism during the pulverization process, and mostly achieve this by setting up a multi-stage pulverizing mechanism, which will increase the cost of the equipment, increase the energy demand, and reduce the production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a phosphogypsum pulverizing device, comprising:

[0007] A frame, on which a rotating shaft driven by a motor is provided, and multiple sets of hydraulic breakers are evenly distributed along its axis in the internal area of ​​the frame.

[0008] A screening base is disposed within the frame, and multiple screening troughs are arranged at intervals on the screening base;

[0009] A receiving cylinder, rotatably mounted within the frame along its axis, abuts against the inner arc surface of the screening seat. The receiving cylinder is equipped with a feeding trough and has multiple sets of through slots.

[0010] A drive assembly is disposed on the rotating shaft and connected to the receiving cylinder to convert the rotation of the rotating shaft into driving the rotation of the receiving cylinder.

[0011] Preferably, the end of the screening trough is provided with an inclined groove.

[0012] Preferably, the frame is provided with a feeding hopper, the bottom surface of which is arc-shaped and abuts against the outer surface of the receiving cylinder.

[0013] Preferably, an inspection window is provided on one side of the frame, and a shielding door is also hinged to the frame.

[0014] Preferably, one end of the receiving cylinder is provided with a connecting frame, which is rotatably sleeved on the rotating shaft.

[0015] Preferably, the driving component includes:

[0016] The first gear is mounted on the rotating shaft;

[0017] The second gear is mounted on the connecting frame; and

[0018] A third gear is rotatably mounted on the frame along its axis. A fourth gear is coaxially connected to the third gear. The third gear meshes with the first gear, and the fourth gear meshes with the second gear.

[0019] Preferably, the diameter of the third gear is larger than that of the first gear, and the diameter of the fourth gear is larger than that of the second gear.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In operation, the phosphogypsum to be crushed is fed into the frame. A motor drives the rotating shaft, causing multiple sets of breaker hammers to crush the phosphogypsum. Phosphogypsum that reaches the standard particle size is collected after being screened through a screening trough, while phosphogypsum that does not reach the standard particle size remains on the screening base. During rotation, the rotating shaft controls the rotation of a receiving cylinder inside the frame via a drive assembly. The thickness of the grooves on the receiving cylinder carries the uncrushed phosphogypsum along the surface of the screening base until it reaches a certain height and falls again under its own gravity into the range of motion of the breaker hammers for further crushing. This effectively crushes the phosphogypsum to the standard particle size, achieving particle size control without the need for multi-stage crushing, effectively saving production costs, reducing energy consumption, and improving production efficiency.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0029] Example:

[0030] like Figures 1 to 3As shown, this utility model provides a phosphogypsum crushing device, including a frame 1. A rotating shaft 4, driven by a motor, is mounted on the frame 1. Multiple sets of crushing hammers 5 are evenly distributed along the axis of the rotating shaft 4 within the frame 1. A screening seat 7 is also provided inside the frame 1, with multiple sets of screening grooves 8 spaced apart. A rotatable receiving cylinder 10 is also provided inside the frame 1, abutting against the inner arc surface of the screening seat 7. A feeding trough 11 is provided on the receiving cylinder 10, and multiple sets of through grooves are formed thereon. A feeding hopper 2 is provided on the frame 1, with an arc-shaped bottom surface abutting against the outer surface of the receiving cylinder 10. An inspection window is provided on one side of the frame 1, and a hinged shielding door 3 is also mounted on the frame 1.

[0031] In operation, the phosphogypsum blocks to be crushed are fed into the frame 1 through the feed hopper 2, and then enter the receiving cylinder 10 through the feeding trough 11. Simultaneously, the motor drives the rotating shaft 4 to rotate, causing multiple sets of crushing hammers 5 to move and crush the phosphogypsum. Phosphogypsum that reaches the standard particle size can be discharged from the frame 1 through the screening trough 8 on the screening seat 7 for collection, while phosphogypsum that does not reach the standard particle size is temporarily stored on the screening seat 7. The receiving cylinder 10 can also be controlled to rotate within the frame 1. During rotation, the unscreened phosphogypsum enters multiple sets of through-channels above it, and the thickness of the through-channels causes the phosphogypsum to follow the movement until it reaches a certain height. Then, due to its own gravity, it falls back into the movement space of the crushing hammers 5 for further crushing until all the phosphogypsum reaches the standard particle size.

[0032] like Figure 2 , 3 As shown, in this embodiment, the end of the screening trough 8 is provided with an inclined groove 9. During the process of the receiving cylinder 10 rotating and driving the phosphogypsum to move, some of the phosphogypsum may get stuck in the screening trough 8. When the receiving cylinder 10 drives it to the position of the inclined groove 9, it can be guided out of the screening trough 8 through the inclined groove 9 to avoid the receiving cylinder 10 getting stuck.

[0033] like Figure 3 As shown, in this embodiment, a connecting frame 12 is provided at one end of the receiving cylinder 10, and the connecting frame 12 is rotatably sleeved on the rotating shaft 4. The connecting frame 12 supports the receiving cylinder 10, preventing the entire weight of the receiving cylinder 10 from being applied to the screening seat 7, thus avoiding increased friction and reducing energy consumption.

[0034] like Figure 3As shown, in this embodiment, a drive assembly connected to the receiving cylinder 10 is provided on the rotating shaft 4. The drive assembly converts the rotation of the rotating shaft 4 into the rotation of the receiving cylinder 10. The drive assembly includes a first gear 6 provided on the rotating shaft 4 and a second gear 13 provided on the connecting frame 12. A third gear 14 is rotatably provided on the frame 1. A fourth gear 15 is coaxially connected to the third gear 14. The third gear 14 meshes with the first gear 6, and the fourth gear 15 meshes with the second gear 13.

[0035] During the rotation of the shaft 4, the first gear 6 is driven to rotate. The first gear 6, in turn, drives the fourth gear 15 to rotate through meshing with the third gear 14. The fourth gear 15, in turn, drives the receiving cylinder 10 to rotate through meshing with the second gear 13. The diameter of the third gear 14 is larger than that of the first gear 6, and the diameter of the fourth gear 15 is larger than that of the second gear 13. This allows the shaft 4 to drive the receiving cylinder 10 to rotate at a low speed during the rotation, thereby stably controlling the movement of the unscreened phosphogypsum and improving the reliability of the device during use.

[0036] The specific usage and beneficial effects of this utility model are as follows:

[0037] In operation, the phosphogypsum to be crushed is fed into the frame 1. A motor drives the rotating shaft 4 to rotate, causing multiple sets of breaker hammers 5 to move and crush the phosphogypsum. Phosphogypsum that reaches the standard particle size is collected by passing through the screening trough 8, while phosphogypsum that does not reach the standard particle size remains on the screening seat 7. During rotation, the rotating shaft 4 controls the receiving cylinder 10 to rotate inside the frame 1 via a drive assembly. The thickness of the through-groove on the receiving cylinder 10 carries the uncrushed phosphogypsum along the surface of the screening seat 7 until it reaches a certain height and falls again under its own gravity into the range of motion of the breaker hammers 5 for crushing. This effectively crushes the phosphogypsum to the standard particle size, achieving particle size control without multi-stage crushing, effectively saving production costs, reducing energy demand, and improving production efficiency.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
