Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of thickener screening structure, specifically to a pretreatment screening structure for a thickener used in mining production. Background Technology
[0002] Mining thickeners are continuous thickening and clarification equipment, mainly used for dewatering concentrate and tailings slurries in wet mineral processing operations. They are also widely used for thickening and purifying solid slurries in coal, steel, chemical, building materials, water sources, and sewage treatment industries.
[0003] When using a thickener in mining production, the ore needs to be screened first to remove larger waste materials and leave the fine and tailings materials that meet the specifications. However, most existing mining production thickeners use a pre-treatment screening structure, which often uses a vibrating motor to screen and feed the material. This method has a limited vibration amplitude and is noisy, causing great inconvenience to the screening of ore. Utility Model Content

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0028] like Figure 1-4 As shown, a pretreatment screening structure for a mineral production thickener includes a base 1, which serves as the basic support for the entire device to ensure the stability of the device.

The two ends of the upper support frame 11 are rotatably connected to the hinges 6 and 8 mounted on one swing frame 3 respectively, and the support... Frame 2 11 runs through the interior of suspension frame 1 7. A suspension frame 2 9 is rotatably mounted at the bottom of the upper support frame 2 11 near the bottom of suspension frame 1 7. The two ends of the lower support frame 2 11 are rotatably connected to suspension frame 2 9 and the end swing rod 5 mounted on the other end of swing frame 1 3, respectively. A traction rod 12 is rotatably mounted on one side of the bottom of swing frame 2 4. A traction rod 2 13 is rotatably mounted between swing frame 1 3 and swing frame 2 4. A mounting base 14 is mounted at one end of the base 1. A rotating shaft 1 is rotatably mounted on the top of the mounting base 14. Fixed plates 16 are mounted at both ends of the rotating shaft 15. Limiting plates 17 are symmetrically mounted on the opposite ends of the fixed plates 16. An adjusting seat 18 is slidably mounted inside the limiting plate 17, and one side of the adjusting seat 18 is connected to one end of the traction rod 12. The fixed plate 16 is rotatably connected to the end face of the limiting plate 17, and a top plate 19 is provided at the top. The top plate 19 is internally threaded with a lifting screw 20, which is rotatably connected to the adjusting seat 18. A terminal pulley 21 is sleeved on the outer middle of the rotating shaft 15. A motor 22 is provided on the top of the support base 14, and the motor 22 is located in front of the rotating shaft 15. A small pulley 23 is provided at the output end of the motor 22. A medium pulley 24 matching the small pulley 23 is rotatably mounted on the top of the support base 14. A reduction belt pulley 25 matching the terminal pulley 21 is provided on one side of the medium pulley 24. Screening boxes 26 are provided inside both the support frame 10 and the support frame 21, and the screening boxes 26 are distributed vertically. The bottom of each screening box 26 is provided with... The screen box 26 is equipped with a water inlet pipe 27 and a powder screen plate 28 inside. A front-to-back crossbeam 29 and a second crossbeam 30 are located at the top of one end of the screen box 26. Both crossbeams 29 and 30 are equipped with lifting screws 31. A sorting plate 32 is located at the bottom of one set of lifting screws 31 on the upper screen box 26, with guide plates 33 on both sides of the sorting plate 32. A guide plate 34 is located at the bottom of one set of lifting screws 31 on the lower screen box 26, and a sealing plate 35 is located at the bottom of another set of lifting screws 31 on the screen box 26. The output end of the upper screen box 26 has a front-to-back discharge chute 36 and a recovery chute 37, with the discharge chute 36 located inside the guide plate 33.The first recycling trough 37 is located at one end of the guide plate 33. The output end of the lower discharge trough 36 has a second recycling trough 38 and a second discharge trough 39 distributed front and back. The second recycling trough 38 is located on both sides of the guide plate 34. When the device is in use, the ore is first fed into the upper screen box 26. The end swing rods 5 and hinges 6 on the swing frames 3 at both ends form a rotational traction on both ends of the support frame 10. The suspension frame 7 forms a rotational traction on the middle part of the support frame 10. The hinges 6 and 8 on one swing frame 3 form a rotational traction on both ends of the upper support frame 11. The traction and suspension frame 29 and the end swing rod 5 on the other end swing frame 13 form a rotational traction on both ends of the lower support frame 211. The support frame 10 and support frame 211 are connected to two sets of screen boxes 26. The swing frame 24 is rotatably connected to the traction rod 12.

The terminal pulley 21, the small pulley 23, the medium pulley 24, and the reduction pulley 25 constitute a reduction transmission structure. When the motor 22 starts, it will drive the terminal pulley 21 to rotate through the belt. This drives the traction rod 12 to reciprocate, which in turn drives the swing frame 4 to reciprocate. The swing frame 4 is movably connected to the traction rod 13, thereby driving the two sets of screening boxes 26 to reciprocate horizontally synchronously, achieving the purpose of screening and discharging materials. One end of the traction rod 12 is movably connected to the adjusting seat 18, which is movably positioned between the limiting plates 17 and its position is adjusted by the lifting screw 20. When the position of the adjusting seat 18 changes, the height of one end of the traction rod 12 also changes accordingly, thus allowing the traction rod 12 to reciprocate. The swing amplitude can be flexibly adjusted to meet the screening requirements under different working conditions, making the device more flexible. Screened ore in the upper screening box 26 falls from its bottom. The remaining incompletely screened ore is guided by the sorting plate 32 and guide plate 33, falling through the recovery trough 37 into the lower screening box 26 for secondary screening. The ore after secondary screening falls from the bottom of the screening box 26, and waste ore is guided by guide plate 34 to the discharge trough 39. This achieves secondary separation of the ore, further improving the screening effect and preventing ore that meets specifications from being screened out.
