Description

Technical Field

[0001] The invention relates to the technical field of spiral chutes, in particular to automatic mineral processing equipment using spiral chutes. Background Art

[0002] Spiral chute automatic mineral processing equipment is a kind of mining machinery equipment, which mainly uses the special geometric shape of the spiral chute and the principle of water flow dynamics to perform preliminary cleaning of raw coal and stratify it according to density.

[0003] The existing device mixes ore and water to form a slurry, which is then evenly fed into the top of a spiral trough via a feed chute. As the slurry flows downward along the spiral trough, due to the trough's inherent inclination and spiral structure, it is affected not only by gravity but also by changes in the centrifugal force field. Furthermore, within the trough, particles in the slurry are subject to varying forces depending on their density. Under the combined effects of gravity and centrifugal force, denser particles (such as heavy minerals) tend to overcome the resistance of the water flow and migrate toward the inside or bottom of the trough, while less dense particles (such as light minerals and mud) are more easily carried away by the water flow, tending to the outside or top of the trough. This differential movement achieves natural stratification by density.

[0004] In order to increase the turbulence and mixing degree of the ore pulp, the entrainment of light minerals in heavy minerals can be reduced by high-frequency oscillation, thereby improving the sorting efficiency of the ore pulp. For example, a spiral chute beneficiation device with publication number CN210729823U includes a frame, a spiral chute is installed on the inner side of the frame, a feed hopper is installed in the middle of the top of the frame, a cutter and a receiving hopper combination is installed on the inner side of the bottom of the frame, a vibration device is installed at the bottom of the frame, and the vibration device includes a base frame, which is arranged below the frame and is frame-shaped. The top of the base frame is fixedly connected to a base, and a pull rod is installed on the opposite surface of the base and the frame, and a spring is provided on the surface of the pull rod. There are four springs.

[0005] The vibration of the above-mentioned spiral chute mineral processing device mainly relies on the vibration motor and the spring arranged at the bottom of the frame to achieve high-frequency oscillation of the entire device. Since the frame as a supporting structure is heavy, the inertia caused by the vibration of the entire device also increases synchronously. Therefore, the present invention proposes a spiral chute automatic mineral processing equipment in which the frame is stationary and the spiral chute vibrates. Summary of the Invention

DETAILED DESCRIPTION In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings: Example: like Figures 1 to 8 As shown, the present invention provides a spiral chute 2 automatic ore concentrator, comprising: Frame 1, fixed on the ground; The spiral chute 2 is provided on the frame 1; The feeder 3 is provided on the upper part of the frame 1 and is located above the spiral chute 2; The vibration mechanism 4 is rotatably arranged in the middle of the spiral chute 2 and is connected to the lower end of the discharger 3 to drive the spiral chute 2 and the discharger 3 to vibrate on the frame 1.

[0022] See also Figure 2 The spiral chute 2 includes a first spiral chute 21 and a second spiral chute 22. Both the first spiral chute 21 and the second spiral chute 22 are wound around the rotating shaft 42 of the vibration mechanism 4 and slidably mounted on the frame 1, allowing the first spiral chute 21 and the second spiral chute 22 to vibrate vertically on the frame 1. The lower discharge ports of the first spiral chute 21 and the second spiral chute 22 are located on the same horizontal line and are arranged in opposite directions. Furthermore, the first spiral chute 21 and the second spiral chute 22 are multi-section detachable splicing structures to facilitate daily maintenance and replacement and repair.

[0023] See also Figure 2 , a crossbeam 14 is provided on the upper end of the frame 1, and the upper end of the rotating shaft 42 is rotatably provided on the crossbeam 14 through a bearing. Further, a crossbeam 14 for limiting the rotating shaft 42 is also provided at the bottom of the frame 1.

[0024] See also Figure 2 The discharger 3 is provided with two discharge ports 34 , which are respectively located above the first spiral chute 21 and the second spiral chute 22 .

[0025] See also Figure 5The present invention further includes an annular fixing frame 5 , which is fixed on the frame body 1 to enhance the strength of the frame body 1 .

[0026] The present invention also includes a discharger connected to the end of the spiral chute 2, with its outlet connected to the outside via a hose. The discharger is a circular structure with a through hole in the center to facilitate the rotation of the shaft 42. A partition is provided in the middle of the discharger to form two silos to discharge the first spiral chute 21 and the second spiral chute 22 respectively.

[0027] As another embodiment of the present invention, Figure 7 and Figure 8 As shown, the frame 1 is provided with a plurality of rectangular through-slots 11 spaced evenly in the vertical direction. A first spiral chute 21 and a second spiral chute 22 are fixedly provided with a limiting protrusion 20. A limiting rod 12 is provided within the rectangular through-slots 11, and the limiting protrusion 20 slides over the limiting rod 12. Springs 13 are provided at both ends of the limiting rod 12, and the springs 13 abut against the limiting protrusions 20, allowing the first spiral chute 21 and the second spiral chute 22 to slide over the limiting rod 12 via the limiting protrusions 20. The limiting protrusion 20 of the present invention is a cylindrical structure with a through hole provided therein, allowing it to slide over the limiting rod 12. The limiting rod 12 passes through each rectangular through-slot 11 through a through hole on the support rod of the frame 1, thereby slidingly engaging with the limiting protrusion 20 located within the rectangular through-slot 11.

[0028] See also Figure 2 and Figure 6 The vibration mechanism 4 also includes a drive motor and a guide member 43. The drive motor is arranged at the bottom of the frame 1. A plurality of annular corrugated grooves 45 are arranged on the rotating shaft 42 at intervals along the axial direction. The guide member 43 is detachably arranged on the first spiral chute 21 and the second spiral chute 22. The guide member 43 is located in the annular corrugated groove 45, so that when the rotating shaft 42 rotates, the annular corrugated groove 45 is driven to rotate, and the up and down movement on the first spiral chute 21 and the second spiral chute 22 is realized through the guide member 43.

[0029] Furthermore, a rectangular rod is provided at the output end of the driving motor or the output end of the reducer of the present invention, a rectangular groove is provided at the end of the rotating shaft 42, the rectangular rod and the rectangular groove are slidably plugged into each other, a spring is provided at the end of the rectangular rod, and the spring abuts against the bottom of the rectangular groove. The above technical solution can effectively reduce the influence of the vibration of the spiral chute 2 on the driving motor during the rotation of the rotating shaft 42.

[0030] As another embodiment of the present invention, Figure 2 and Figures 6 to 8As shown, it also includes a second guide member 44, which is detachably arranged at the end of the rotating shaft 42; a jumping rod 31 is provided at the end of the feeder 3, and an annular corrugated groove 46 is provided on the jumping rod 31. The end of the rotating shaft 42 is a tubular structure, and the end of the rotating shaft 42 is sleeved on the jumping rod 31 so that the second guide member 44 is located in the annular corrugated groove 46.

[0031] Furthermore, the annular corrugated groove 1 45 and the annular corrugated groove 2 46 of the present invention have a semicircular vertical cross-section. The front ends of the guide members 1 43 and 2 44 are semispherical structures, and the guide members 1 43 and 2 44 are provided with external threads to facilitate fixed installation on the rotating shaft 42 and the spiral chute 2.

[0032] Furthermore, guide rollers can be used at the ends of guide member 1 43 and guide member 2 44 instead of the semi-spherical structure. At this time, the vertical cross-sections of annular corrugated groove 1 45 and annular corrugated groove 2 46 are rectangular structures, and the impact force of the first spiral chute 21 and the second spiral chute 22 on the annular corrugated groove 1 45 is reduced by the rolling contact between the guide rollers and the annular corrugated groove 1 45.

[0033] See also Figure 2 A plurality of limit rods 32 are provided on the outer ring of the feeder 3. The limit rods 32 are slidably located on the upper part of the frame 1. A spring 33 is sleeved on the limit rod 32. One end of the spring 33 is fixedly connected to the upper part of the frame 1 so as to limit the feeder 3 in the vertical direction while ensuring that it vibrates in the vertical direction under the rotation of the rotating shaft 42.

[0034] As another embodiment of the present invention, Figure 2 As shown, the annular corrugated groove 45 includes a first annular corrugated groove 451 for controlling the vibration of the first spiral chute 21, and a second annular corrugated groove 452 for controlling the vibration of the second spiral chute 22. The crest of the first annular corrugated groove 451 and the trough of the second annular corrugated groove 452 are arranged opposite to each other in the vertical direction, so that the first spiral chute 21 and the second spiral chute 22 are synchronously vibrated in the vertical direction on the frame 1 in opposite directions, thereby realizing the relative vibration of the first spiral chute 21 and the second spiral chute 22, so that the first spiral chute 21 and the second spiral chute 22 can offset each other during vibration to further reduce the inertial impact force of the device.

[0035] See also Figure 7 and Figure 8 As shown, the crests and troughs of the annular corrugated groove 2 46 of the present invention are arranged vertically opposite to the crests and troughs of the first annular corrugated groove 1 451 or the second annular corrugated groove 1 452, so that the feeder 3 and the first spiral chute 21 or the second spiral chute 22 vibrate synchronously in the same direction.

[0036] Furthermore, the multiple spiral chutes 2 automatic concentrators of the present invention can be connected by setting an annular sprocket or pulley at one end of the rotating shaft 42, and relying on a transmission chain or transmission belt to propose a transmission relationship between the multiple spiral chutes 2 automatic concentrators, so that a single drive motor can control the vibration of the spiral chutes 2 on the multiple spiral chutes 2 automatic concentrators.

[0037] Furthermore, the number of the spiral chutes 2 of the present invention is not limited to two, but may be four. When there are four spiral chutes 2, the jumping directions of every two spiral chutes 2 are the same.

[0038] Working Principle: The feeder 3 discharges the slurry through the discharge port 34 to the upper ends of the first and second spiral chutes 21, 22, respectively, which overlap in spirals. The slurry is sorted by the first and second spiral chutes 21, 22 and then discharged by the discharger at the bottom of the spiral chute 2. During this process, the drive motor drives the rotating shaft 42 to rotate in the middle of the spiral chute 2. The annular corrugated groove 1 45 and annular corrugated groove 2 46 cause the spiral chute 2 and the feeder 3 to jump vertically, thereby achieving vibration of the spiral chute 2 and the feeder 3 on the frame 1.
