Description

Technical Field

[0001] This utility model relates to the field of grading and sorting equipment technology, specifically a particle size grading and precision sorting equipment. Background Technology

[0002] The fractional processing of weathered phosphate rock is a chemical mineral processing technology, specifically involving the fractional processing methods for weathered phosphate rock. It involves a series of steps including crushing, grinding, grading, and fractional processing to effectively separate phosphate minerals of different components and particle sizes from the ore, thereby producing different products such as high-grade phosphate concentrate and low-grade phosphate concentrate. In the fractional processing of weathered phosphate rock, grading and sorting equipment plays a crucial role.

[0003] Utility model patent CN202320602001.8 discloses a submerged single spiral classifier for phosphate rock beneficiation. This submerged single spiral classifier includes a screening box, inside which a rotating shaft is installed, with spiral blades mounted on the shaft. At least two perforated screen plates are installed below the spiral blades inside the screening box. Three discharge ports are opened on the left outer wall of the screening box, with the left end of each perforated screen plate located between two adjacent discharge ports. A guide plate is installed below each discharge port, with the upper guide plate being longer than the lower guide plate. A drive motor for driving the rotating shaft is installed on the right outer wall of the screening box. A feeding port is opened on the top right side of the screening box, and a bottom plate is provided at the bottom of the screening box. By setting multiple perforated sieve plates inside the screening box near the bottom, the phosphate rock after precipitation screening can be screened again according to size, which facilitates subsequent operations on the phosphate rock and increases the functionality of the device, making it easier to use. In addition, by setting guide plates of different lengths, the screened phosphate rock can be discharged out of the screening box separately.

[0004] Although the submerged single-spiral classifier for phosphate ore beneficiation facilitates the classification and screening of phosphate ore, the device still has the following problems in actual use: the multiple screen plates are fixed inside the screening box, making disassembly and assembly inconvenient; and with continuous use, ore accumulation at the screen openings becomes increasingly severe, leading to a decrease in screen throughput and screening efficiency. This phenomenon not only affects the ore classification efficiency but may also damage the screen structure. Therefore, we propose a precision particle size classification and separation device.

The top of the connecting rods is fixed to the bottom of the box. Limiting rings are coaxially fixed on the outer wall of the connecting rods on the upper and lower sides of the base plate. Two springs are sleeved on the outside of the connecting rods to press against the base plate.

[0010] Furthermore, the base has an L-shaped cross-section, and multiple hinges are fixedly connected to the base plate by bolts.

[0011] Furthermore, a side plate is fixed between the right ends of the plurality of insert plates, and two symmetrical handles are fixed to the outer wall of the side plate.

Under the vibration of the box, the phosphate rock can be screened through multiple screens with different screen sizes. This design is not only conducive to the screening of phosphate rock through screens, thus facilitating the grading and sorting of phosphate rock, but also ensures the screening and grading effect of phosphate rock.

[0019] 2. The movable plate, limiting rod, and connecting plate facilitate the fixing of the insert plate, thus ensuring the stability of the screen when screening phosphate ore.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] This embodiment provides a technical solution:

[0033] Please see Figures 1-5 As shown, a particle size classification and precision sorting device includes a hollow box 1. A slot 10 is provided on the right side wall of the box 1, and multiple discharge troughs 11 are provided on the front end face of the box 1. A bracket 14 is fixed to the left end face of the box 1. A threaded rod 15 is rotatably installed in the opening of the bracket 14. Multiple movable plates 16 are threadedly connected to the threaded rod 15. A limit rod 17 is fixed at one bottom end of each movable plate 16. A vibration motor 4 is installed at the bottom of the box 1. A screening assembly 2 is provided at the right end of the box 1. The screening assembly 2 includes an insert plate 22 that inserts into the slot 10. A screen 23 for screening weathered phosphate rock is fixed at the opening of the insert plate 22. A connecting plate 24 is fixed at the left end of the insert plate 22. Limiting holes are provided on the connecting plate 24. The connecting plate 24 passes through the left outer wall of the housing 1. The limiting rod 17 is inserted and engaged with the corresponding limiting hole. An adjustment part is provided at the bottom of the housing 1. The adjustment part includes a base 3. A bottom plate 30 is provided above the base 3. The front end of the bottom plate 30 is hinged to the front end of the top of the base 3. Two electric cylinders 31 are also hinged to the top of the base 3. The piston rod end of the electric cylinder 31 is hinged to the bottom of the bottom plate 30. Connecting rods 32 are slidably installed at the four corners of the bottom plate 30. The top end of the connecting rod 32 is fixed to the bottom of the housing 1. Limiting rings 33 are coaxially fixed on the outer wall of the connecting rod 32 at the upper and lower sides of the bottom plate 30. Two springs 34 are sleeved on the outside of the connecting rod 32 to press against the bottom plate 30.

[0034] In this embodiment, the base 3 has an L-shaped cross-section, and multiple hinges are bolted to the connection between the base 3 and the base plate 30. The L-shaped cross-section design helps stabilize the base 3 and reduces vibration and shaking; the bolted hinge design makes the connection between the base 3 and the base plate 30 secure, preventing it from loosening or falling off, and also facilitates the angle adjustment of the base plate 30.

[0035] In this embodiment, a side plate 20 is fixed between the right ends of the plurality of insert plates 22, and two symmetrical handles 21 are fixed to the outer wall of the side plate 20. The design of the side plate 20 and the handles 21 makes the installation and operation of the insert plates 22 more convenient.

[0036] In this embodiment, a guide rail 140 is fixed to the inner wall of the bracket 14, and a guide groove is provided at one end of the movable plate 16 to slide in connection with the guide rail 140. The design of the guide rail 140 allows the movable plate 16 to slide flexibly, ensuring the stability of the movable plate 16.

[0037] In this embodiment, support bars 12 are fixed to both the left and right ends of the front face of the housing 1. Multiple fixing bolts 120 are threaded onto each support bar 12. Multiple blocking plates 18 are fixed between two support bars 12. Adjustment holes are provided at both ends of the blocking plates 18, and the ends of the fixing bolts 120 are inserted into the adjustment holes. The blocking plates 18 are located at the corresponding discharge troughs 11 and are used to seal the discharge troughs 11. The design of the support bars 12 and fixing bolts 120 makes it easier to assemble and disassemble the blocking plates 18, and also facilitates sealing the discharge troughs 11 using the blocking plates 18.

[0038] In this embodiment, the blocking plate 18 has a rectangular cross-sectional shape, which is larger than the cross-sectional shape of the discharge chute 11. This design allows the blocking plate 18 to better seal the discharge chute 11 and prevent ore leakage.

[0039] In this embodiment, a feed hopper 13 is installed on the top of the housing 1, and the cross-sectional shape of the feed hopper 13 is funnel-shaped. The funnel-shaped feed hopper 13 design can effectively guide the ore into the sorting equipment evenly, reduce the accumulation of ore in the hopper, and improve the feeding efficiency.

[0040] In this embodiment, the insert plate 22 and the connecting plate 24 are integrally formed structures, and the insert plate 22 and the screen 23 are fixedly connected by bolts. The integrally formed design of the insert plate 22 and the connecting plate 24 simplifies the manufacturing and installation process and ensures the connection strength between the insert plate 22 and the connecting plate 24; the bolt-fixed connection between the insert plate 22 and the screen 23 can be more tightly connected and fixed, improving the stability of sorting.

[0041] It is understood that the multiple screens 23 in this embodiment have different apertures, and the apertures of the multiple screens 23 decrease from top to bottom. This design is beneficial for classifying and screening phosphate rock through multiple screens 23.

[0042] It should be added that, in this embodiment, the outer diameter of the limiting ring 33 is larger than the diameter of the connecting rod 32. The setting of the limiting ring 33 plays a limiting role on the spring 34, thereby preventing the spring 34 from dislodging from the connecting rod 32 and ensuring the stability of the device.

[0043] In addition, a handwheel 19 is coaxially keyed to the top of the threaded rod 15 in this embodiment. The handwheel 19 allows the user to easily rotate the threaded rod 15. This design has the advantages of convenient and quick operation, which allows the user to adjust the height of the movable plate 16 by rotating the threaded rod 15.

[0044] It is worth noting that the vibration motor 4 involved in this embodiment is a conventional technology and will not be described in detail here.

[0045] In actual use, the user first turns on the power of the vibration motor 4, and the vibration motor 4 starts to work. The vibration motor 4 drives the box 1 to vibrate. At this time, the phosphate ore enters the box 1 through the feed hopper 13 and falls onto the screen 23. The screen 23 then screens the phosphate ore. Larger particles of phosphate ore fall onto the upper screen 23, while smaller particles fall onto the lower screen 23. As the screen 23 continues to vibrate, the phosphate ore can be continuously screened.

[0046] When unloading is required, the operator first loosens the fixing bolts 120 on both sides. The ends of the fixing bolts 120 then disengage from the blocking plate 18, and the corresponding blocking plate 18 is disassembled. Then, the operator turns on the power to the electric cylinder 31, and the electric cylinder 31 starts to work. The piston rod of the electric cylinder 31 extends and drives the bottom plate 30 to tilt. The bottom plate 30 then drives the box 1 to tilt forward. Once the box 1 is tilted to a suitable angle, the operator stops the power to the electric cylinder 31. At this time, the phosphate ore intercepted at the top of the screen 23 is discharged through the corresponding discharge chute 11.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
