Description

Technical Field

[0001] The invention belongs to the technical field of spiral chutes, and in particular relates to a spiral chute for oxidized ore beneficiation. Background Art

[0002] The spiral chute is a high-efficiency separation equipment developed based on the principle of gravity separation. Its core structure is a spiral trough. When the slurry flows in the trough, different mineral particles have differences in density, particle size and shape. Under the combined action of centrifugal force, water flow force and its own gravity, they are stratified and separated. This equipment is widely used in the separation of minerals with significant density differences such as placer gold, tungsten-tin ores, which can effectively enrich useful minerals and significantly improve the grade of concentrates. However, during long-term continuous operation, the surface of the spiral chute is prone to adherence to sludge film or mineral accumulation. These deposits will change the flow channel morphology, resulting in reduced sorting accuracy, which not only seriously affects the flow characteristics of the slurry, but also aggravates mineral mixing, ultimately leading to a decline in mineral processing indicators and affecting mineral processing efficiency and quality.

[0003] Most existing cleaning methods are water flushing or manual scrubbing. However, water flushing is often difficult to remove stubbornly attached mineral slime films, and has little effect on already formed mineral agglomerates. Although manual scrubbing can handle some stubborn deposits, it consumes labor and has low cleaning efficiency.

[0004] To this end, we provide a spiral chute for oxide ore beneficiation to solve the above problems. Summary of the Invention

[0021] See also Figures 1 to 6 The present invention is a spiral chute for oxide ore beneficiation, comprising a stand 100, a frame body 101, two centrally symmetrical screws 103 rotatably connected to the interior of the frame body 101, a central column 102 fixedly connected to the center of the frame body 101, a spiral chute 200 fixedly connected to the exterior of the central column 102, and a lifting drive assembly 400 provided on the top of the frame body 101; The mounting frame 300 includes an annular frame 301 movably sleeved inside the frame body 101. The annular frame 301 is fixedly connected to the outside of two threaded sleeves 302, which are respectively threadedly sleeved on the outside of two screw rods 103. The mounting frame 300 achieves stable lifting along the frame body 101 through the threaded cooperation between the threaded sleeves 302 and the screw rods 103, and can drive the cleaning and flushing components connected to its bottom to move to different height positions of the spiral chute 200, effectively expanding the cleaning range and improving the comprehensiveness of the cleaning work; The mounting assembly 500 includes an outer sleeve 501 fixedly connected to the bottom of the mounting frame 300. The inner sleeve 502 is rotatably connected to the interior of the outer sleeve 501. The inner sleeve 502 is installed with a brush trough assembly 700 for cleaning the spiral chute 200. The mounting assembly 500 connects the brush trough assembly 700 to the mounting frame 300. The rotational connection between the outer sleeve 501 and the inner sleeve 502 provides a flexible movement basis for the rotational cleaning of the brush trough assembly 700, so that the brush trough assembly 700 can better fit the spiral surface of the spiral chute 200 for cleaning operations. The rotary drive assembly 600 includes a rotary motor 601 fixedly connected to the outside of the outer sleeve 501 and a ring gear 602 fixedly connected to the outside of the inner sleeve 502. The output end of the rotary motor 601 is fixedly connected to a drive gear 603 meshing with the ring gear 602. The outer sleeve 501 is provided with a flushing assembly 800 for flushing the spiral chute 200. The lifting drive assembly 400 includes a lifting motor 401 fixedly connected to the top center of the frame 101 and a first bevel gear 404 fixedly connected to the top of the screw 103. The output end of the lifting motor 401 is fixedly connected to the driving bevel gear 402. The top of the frame 101 is rotatably connected to two driving rods 403 symmetrical with the lifting motor 401 as the center. The two ends of the driving rod 403 are respectively fixedly connected to a driven bevel gear 406 meshing with the driving bevel gear 402 and a second bevel gear 405 meshing with the first bevel gear 404. The rotation of the screw 103 is realized through the gear transmission structure, which drives the mounting frame 300 to rise and fall, so that the cleaning position can be adjusted.

[0022] Specifically, the outer portion of the inner sleeve 502 is fixedly connected with a snap ring 502a, the bottom of the outer sleeve 501 is fixedly connected with a clamping seat 501a, and the snap ring 502a is rotatably connected to the inner portion of the clamping seat 501a. The cooperation between the snap ring 502a and the clamping seat 501a further enhances the stability and reliability of the rotational connection between the inner sleeve 502 and the outer sleeve 501, prevents the inner sleeve 502 from deflecting or shaking during the rotation process, and ensures that the cleaning operation of the brush slot assembly 700 can be carried out accurately and stably. The brush trough assembly 700 includes a mounting base 701 fixedly connected to the inner wall of the inner sleeve 502, and a mounting plate 702 is installed inside the mounting base 701. Two sliding rods 704 are movably sleeved inside the mounting plate 702. The bottom of the two sliding rods 704 is fixedly connected to a second brush plate 703, and the top of the two sliding rods 704 is installed with a top plate 706. The mounting plate 702 is driven to rotate by the mounting base 701, and the mounting plate 702 drives the second brush plate 703 to rotate in contact with the spiral chute 200 through the sliding rod 704, so that the spiral chute 200 can be cleaned.

[0023] Furthermore, a spring 705 is movably sleeved on the outside of the slide bar 704, and the spring 705 is located between the second brush plate 703 and the mounting plate 702. The setting of the spring 705 plays the role of elastic buffering and pressure regulation, adjusting the pressure of the second brush plate 703 to ensure that the second brush plate 703 always closely adheres to the surface of the spiral chute 200, avoiding incomplete cleaning due to insufficient pressure; The mounting plate 702 and the mounting seat 701, as well as the top plate 706 and the two slide bars 704, are all detachably connected by bolts. The detachable bolt connection facilitates installation, disassembly, and maintenance of the various components of the brush trough assembly 700. When the second brush plate 703 is worn or other components are damaged, they can be quickly replaced, thereby reducing equipment maintenance costs and improving the maintainability and service life of the equipment. The outside of the threaded sleeve 302 is fixedly connected to two symmetrical first brush plates 303, and the bristles of the first brush plates 303 fit into the outside of the screw 103. The first brush plates 303 can clean the mineral powder, impurities, etc. attached to the surface of the screw 103 in time during the lifting and lowering process of the threaded sleeve 302, prevent these impurities from entering the threaded mating parts, avoid increased wear or jamming between the screw 103 and the threaded sleeve 302 due to the accumulation of impurities, and ensure normal transmission of the screw 103 and the threaded sleeve 302.

[0024] The operation process of this embodiment is as follows: when the spiral chute 200 needs to be cleaned, the lifting motor 401 is started, and the lifting motor 401 drives the driving bevel gear 402 to rotate. The driving bevel gear 402 drives the driving rod 403 to rotate through the meshing driven bevel gear 406. The second bevel gear 405 at the other end of the driving rod 403 is meshed with the first bevel gear 404, thereby rotating the screw 103. When the screw 103 rotates, the annular frame 301 is driven by the threaded sleeve 302 to move up and down inside the frame body 101, thereby adjusting the height of the mounting frame 300. At the same time, Start the rotating motor 601, and the output end of the rotating motor 601 drives the driving gear 603 to rotate. The driving gear 603 engages with the ring gear 602, and then drives the inner sleeve 502 to rotate in the outer sleeve 501. When the inner sleeve 502 rotates, the mounting plate 702 is driven to rotate through the mounting seat 701, and the mounting plate 702 drives the second brush plate 703 to rotate through the slide rod 704, so that the spiral chute 200 can be cleaned, reducing the cleaning time, improving the overall work efficiency, and at the same time improving the cleaning quality, preventing the accumulation of impurities from affecting the mineral sorting effect of the spiral chute 200. Example 2

[0025] See also Figure 3 Based on the specific embodiment 1, the flushing assembly 800 includes an annular tube 801 fixedly connected to the inner wall of the outer sleeve 501, a plurality of nozzles 802 are evenly installed on the inner side of the annular tube 801 along the circumferential direction, and a connecting tube 803 is installed on the outside of the annular tube 801.

[0026] The operation process of this embodiment is: clean water is injected into the annular pipe 801 through the connecting pipe 803, and then sprayed out through multiple nozzles 802 evenly distributed along the circumference inside the annular pipe 801, which can flush the spiral chute 200, thereby improving the cleaning effect of the spiral chute 200.

[0027] In addition, it should be noted that the components not described in detail herein are prior art.
