Description

Technical Field

[0001] The invention relates to the technical field of ore dressing equipment, and in particular to an automatic chute mechanism for ore dressing equipment. Background Art

[0002] In the beneficiation process of placer gold ore and rock gold ore, the chute is a commonly used gravity sorting equipment. Through the flow of slurry in the inclined chute, high-density minerals such as gold particles are settled and adhered to the gold-adhesive blanket at the bottom of the chute, such as velvet blanket, felt or rubber blanket with brushes, while light mud and sand are discharged with the water flow, thereby achieving initial enrichment of minerals.

[0003] After a period of operation, the bristles or velvet surface of the gold-catching blanket of the traditional chute equipment will be filled with gold particles and other heavy minerals, which will result in the inability to effectively adsorb the gold particles when the subsequent slurry flows through, resulting in a decrease in the recovery rate. At this time, production must be stopped and the gold-catching blanket must be manually removed for cleaning, i.e., "clearing" operation, to restore its gold-catching ability. Manual clearing requires frequent disassembly and assembly of the gold-catching blanket, which is cumbersome to operate, especially in large-scale continuous mineral processing systems, where the frequency of clearing is high, which seriously affects production efficiency. During manual cleaning, some fine gold particles may be lost due to improper operation, and it is difficult to thoroughly clean the accumulated gold at the root of the bristles, resulting in fluctuations in the recovery rate. In addition, manual clearing is labor-intensive, and each clearing needs to be interrupted for a long time, which affects the continuity of mineral processing and reduces equipment utilization. Summary of the invention

[0006] The chute body is also provided with a guide assembly. When the power mechanism drives the gold-adhering blanket to flip and be above the bottom surface of the chute body, the gold-adhering blanket opens the downward gold-adhering brush through the action of the guide assembly.

[0007] Furthermore, the power mechanism comprises a flexible transmission chain, and one of the side edges and the middle portion of the gold-bonding blanket are connected to the flexible transmission chain.

Specifically, through the cooperation of the arc plate and the straight epitaxial plate, the triple effects of anti-blocking, water flow optimization, and improved gold particle recovery can be achieved.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0024] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0025] An embodiment of an automatic chute mechanism for ore dressing equipment provided by the present invention: like Figures 1 to 9 As shown, The invention comprises an inclined chute body 1 and a gold-adhesive blanket 2 arranged on the chute body 1, and a gold-adhesive brush 21 is arranged on the gold-adhesive blanket 2. A feeding barrel 7 is arranged at the upper end of the chute body 1, a conveying dragon 71 is arranged in the feeding barrel 7, and a discharge port 72 is arranged on the side of the feeding barrel 7 opposite to the lower end of the chute body 1.

[0026] Specifically, the mixture of gold-containing minerals, silt and water sorted out in the previous sequence is fed into the right high end position in the chute body 1 through the feeding barrel 7 at the upper end and the conveying dragon 71 arranged in the feeding barrel 7. Under the action of water flow and gravity, silt and gold-containing mineral particles flow from the high end to the bottom end. The target mineral-containing minerals are precipitated downward by gravity and fall between the gold-binding brushes 21 on the gold-binding blanket 2. The sand particles are washed down with the water flow and enter the dewatering screen of the first process.

[0027] In this embodiment, a power mechanism 3 for driving the gold-adhesive blanket 2 to flip is provided in the chute body 1. Specifically, the power mechanism 3 includes a flexible transmission chain 31, and one of the side edges and the middle portion of the gold-adhesive blanket 2 are connected to the flexible transmission chain 31. Among them, a rotating shaft is provided at the lower end of the chute body 1 for rotation support, and a transmission gear matched with the flexible transmission chain 31 is provided on the rotating shaft, and the flexible transmission chain 31 is driven to transmit by the rotation of the rotating gear. The flexible transmission chain 31 can drive the gold-adhesive blanket 2 to flip during the rotation process, so as to switch the gold-adhesive blanket 2 between the adsorption and cleaning modes.

[0028] The upper end of the gold-bonding blanket 2 is wound around the outside of the feeding barrel 7 through a flexible transmission chain 31. In order to make the gold-bonding blanket 2 turn over more smoothly, an outer barrel can be rotatably arranged outside the feeding barrel 7 through a bearing.

[0029] In this embodiment, a water pipe assembly 4 is provided in the chute body 1, and the water pipe assembly 4 includes a transversely arranged branch pipe 41, and a water spray port 411 with an upward opening is provided on the branch pipe 41. The water pipe assembly 4 also includes a main pipeline arranged in the chute body 1 and distributed from top to bottom, and the transversely arranged branch pipes 41 are arranged at intervals on both sides of the main pipeline. The water spray port 411 with an upward opening can flush the gold-containing material stuck in the gold-adhering brush 21 by spraying high-pressure water when the gold-adhering blanket 2 is in the cleaning mode.

[0030] In this embodiment, a rotating shaft 5 is rotatably provided on one side of the branch pipe 41, and an arc plate 51 is provided on the rotating shaft 5. Specifically, an arc opening sleeve 511 is provided at the end of the arc plate 51, and the arc opening sleeve 511 is fixedly sleeved on the rotating shaft 5 by interference fit.

[0031] When the gold-adhesive blanket 2 is on the bottom surface of the chute body 1, the arc plate 51 covers the water outlet 411. When the power mechanism 3 drives the gold-adhesive blanket 2 to flip over and be above the bottom surface of the chute body 1, the rotating shaft 5 rotates and moves the arc plate 51 to flip so that the arc plate 51 is separated from the water outlet 411.

[0032] It should be noted that when the gold-binding blanket 2 is on the bottom surface of the chute body 1, the arc plate 51 can be attached to the branch pipe 41, and the arc plate 51 covers the water outlet 411. On the one hand, it can prevent mud and sand from rushing into the water outlet 411 to cause blockage, and on the other hand, the arc plate 51 can form an upwardly protruding physical barrier, which can guide the water flow to form local turbulence and upturned vortexes. The vortexes cause the water flow to repeatedly scour the surface of the gold-binding blanket 2, thereby increasing the contact probability between fine gold and the gold-binding blanket. The tumbling action promotes the stratification of light and heavy minerals, and gold particles are more likely to settle on the surface of the gold-binding blanket 2, avoiding edge deposition caused by traditional flat channels and improving the overall recovery rate.

[0033] Among them, a straight extension plate 52 is provided at the free end of the arc plate 51. When the arc plate 51 is clamped on the branch pipe 41 to cover the water spray outlet 411, the straight extension plate 52 points obliquely downward toward the gold-bonding blanket 2 and a gap is left between the end of the straight extension plate 52 and the gold-bonding blanket 2.

[0034] The inclination angle of the straight epitaxial plate 52 forces the water to be directed to the surface of the gold-adhesive blanket 2 after passing through the vortex formed by the curved plate 51, thereby increasing the uniformity of the water flow covering the gold-adhesive blanket and avoiding the decrease in the recovery rate caused by the dispersion of the water flow. The gap at the end of the straight epitaxial plate 52 allows part of the water flow to carry light sediment to pass through, thereby avoiding the formation of a siltation layer on the surface of the gold-adhesive blanket 2, which affects the adsorption of gold.

[0035] Specifically, through the cooperation of the arc-shaped plate 51 and the straight extension plate 52, the triple effects of anti-clogging, water flow optimization and improved gold particle recovery can be achieved.

[0036] A motor for driving the rotating shaft 5 to rotate is provided on the side plate of the chute body 1 .

[0037] A notch 512 is disposed at the end of the arc-shaped plate 51 , and the bottom edge of the notch 512 is connected to the outside.

[0038] When the arc plate 51 is turned over so that the water outlet 411 is flushing, the notch 512 can assist in draining sand, thereby preventing the accumulation of gold sand on the concave surface of the arc plate 51 .

[0039] The rotating shaft 5 is also provided with a lower arc-shaped limit plate 53 corresponding to the notch 512 . The end of the lower arc-shaped limit plate 53 is provided with an arc-shaped sleeve 531 . The arc-shaped sleeve 531 is fixedly sleeved on the rotating shaft 5 by interference fit.

[0040] The lower arc-shaped limiting plate 53 can improve the stability of the rotating shaft 5 and help to extend the service life of the equipment.

[0041] In this embodiment, a guide assembly 6 is further provided on the chute body 1. When the power mechanism 3 drives the gold-adhesive blanket 2 to flip and be above the bottom surface of the chute body 1, the gold-adhesive blanket 2 opens the downward gold-adhesive brush 21 through the action of the guide assembly 6.

[0042] Through the function of the guide assembly 6, the opening and closing of the gold-catching brush 21 is realized through mechanical linkage without manual intervention, thereby improving efficiency and reducing labor intensity. The gold-catching brush 21 is only opened during flipping and cleaning to prevent gold particles from falling off due to water flow impact during the gold catching process.

[0043] The guide assembly 6 includes upper pressing rollers 61 that are rotatably supported and arranged at intervals, and lower arching guide wheels 62 are rotatably arranged between adjacent upper pressing rollers 61. Both the upper pressing rollers 61 and the lower arching guide wheels 62 are rotatably supported by two side plates of the chute body 1.

[0044] The part of the flexible transmission chain 31 in the middle corresponding to the guide assembly 6 is redirected into a continuous S shape through the cooperation of the upper pressure roller 61 and the lower arch guide wheel 62.

[0045] Through the alternating action of the plurality of upper pressing rollers 61 and the lower arching guide wheels 62, the gold-adhering blanket 2 is bent repeatedly, and the gold-adhering brush 21 is fully opened, so that the gold particles can be easily dropped off or cleaned.

[0046] In this embodiment, a sedimentation container 8 is provided below the end of the chute body 1, and a flip plate 11 corresponding to the sedimentation container 8 is provided on the bottom plate of the chute body 1. Specifically, the flip plate 11 is rotatably supported by a support shaft, and a motor for driving the support shaft to rotate is provided on the side of the chute body 1. The flip plate 11 is flipped by the rotation of the support shaft.

[0047] A guide baffle 81 is provided in the sedimentation container 8 , and a wastewater overflow notch 82 is provided on the outer side of the sedimentation container 8 .

[0048] Specifically, when in the sorting state, the flip plate 11 is flush with the lower end surface of the chute body 1, so that the silt enters the subsequent dewatering screen under impact. When the chute body 1 is in the clearing state, the flip plate 11 flips upward to cover the end of the chute body 1, so that the minerals are collected in the sedimentation container 8.

[0049] When the automatic chute mechanism for the mineral processing equipment of this embodiment is used, after the chute body 1 has been sorted for a period of time, the gaps of the gold-binding brushes 21 on the gold-binding blanket 2 will be filled with mineral particles. If the gold-containing substances are not cleared at this time, the loss of gold-containing substances will occur. An appropriate time interval for clearing the chute is set according to the content of different mining areas. When clearing the chute is required, the gold-binding blanket 2 is turned over so that the gold-binding brushes 21 face downward, and other operating units of the mineral processing equipment are turned off. The water supply system is switched to the clearing pipeline, i.e., the water pipe assembly 4. At the same time, the flip plate 11 is turned upward to cover the end of the chute body 1, and the arc plate 51 is turned over so that the water outlet 411 is opened. The high-pressure water sprayed from the water outlet 411 forms a water curtain to flush the gaps of the gold-binding brushes 21, and flush the gold-containing substances on the surface. After the alternating action of multiple upper pressing rollers 61 and lower arching guide wheels 62, the gold-adhesive blanket 2 is bent repeatedly, the gold-adhesive brush 21 is fully opened, and then the high-pressure water curtain is used to rinse the minerals thoroughly. Finally, the minerals fall into the sedimentation container 8 through the tail end of the chute body 1 under the impact of water, and finally the automatic chute cleaning is realized.
