Description

Technical Field

[0001] The invention relates to the technical field of jigs, in particular to a vibration-force driven jig. Background Art

[0002] Jig is a gravity ore dressing equipment in ore dressing equipment. Jig ore dressing belongs to deep trough sorting operation. It uses water as the ore dressing medium and utilizes the difference in specific gravity of the selected mineral and gangue. Water flows through the screen plate into the jig chamber, causing the bed to rise and become slightly loose. The particles with high density enter the lower layer due to the large local pressure and sedimentation velocity, and the particles with low density are transferred to the upper layer. When the water flow drops, the small particles with high density also enter the lower layer through the gradually dense bed gap. Jigs are mostly diaphragm type. The stroke and stroke frequency can be flexibly adjusted according to the specific gravity of the selected mineral. They are widely used in gravity ore dressing of metal and non-metal such as placer gold, hematite, limonite, manganese ore, tungsten ore, tin ore, lead ore, antimony ore, chromite, mercury ore, nickel ore, pyrite, specularite, barite, fluorite, garnet, etc. It can also be used to treat chromium slag, silicon manganese slag, nickel slag, copper slag, siderite slag, etc.

The top of the frame 1 is provided with a water tank box 7. The top of the water tank box 7 is provided with a jigger box 2.

The vibration motor body 15 adopts the MVE series standard vibration motor of Shaoxing Ouli-Wolong Vibration Machinery Co., Ltd. A screen 18 is installed inside the jigger box 2 on one side of the baffle plate 11. The screen 18 is slidably connected to the jigger box 2.

[0029] A concentrate collecting box 10 is installed on the outer wall of the frame 1 on one side of the baffle 11, a fine concentrate discharge valve 9 is installed at the center position of the bottom end of the water tank box 7, a water inlet 8 is installed inside the water tank box 7 below the jig box 2, and the water inlet 8 extends to the outside of the water tank box 7, an elastic sealing diaphragm 3 is provided on the top of the frame 1 on one side of the jig box 2, a front connecting belt 4 is installed at one end of the elastic sealing diaphragm 3 close to the jig box 2, and the elastic sealing diaphragm 3 is movably connected to the jig box 2 through the front connecting belt 4, a rear connecting belt 5 is installed at one end of the elastic sealing diaphragm 3 close to the water tank box 7, and the elastic sealing diaphragm 3 is connected to the water tank box 7 through the rear connecting belt 5, and the jig box 2 and the water tank box 7 are formed in a relatively sealed state under the cooperation of the rear connecting belt 5, the front connecting belt 4 and the elastic sealing diaphragm 3.

[0030] Upper reinforcing rods 13 are installed inside the jigging machine box 2 on both sides of the support column 14 , multiple groups of lower reinforcing rods 6 are installed inside the jigging machine box 2 below the support column 14 , and a feed outlet 17 is installed at the top of the jigging machine box 2 .

[0031] Upper brackets 19 are installed on the outer walls on both sides of the jigging box 2 above the frame 1, and springs 20 are installed at the bottom ends of the upper brackets 19. The springs 20 play a role of elastic support. Lower brackets 21 are installed at the bottom ends of the springs 20, and the lower brackets 21 are fixedly connected to the frame 1.

[0032] The ore enters the jig box 2 from the discharge port 17, and the external water source enters the water tank box 7 through the water inlet 8. The water source fills the jig box 2 above the screen 18. The elastic sealing diaphragm 3 cooperates with the front connecting belt 4 and the rear connecting belt 5 to play a sealing role to prevent the water source from overflowing from the gap between the jig box 2 and the frame 1. When the ore enters the jig box 2, the vibration motor body 15 is turned on. The vibration motor body 15 vibrates the jig box 2 under the support of the support column 14 and the vibration frame 16. The spring 20 elastically supports the connection between the lower bracket 21 and the upper bracket 19. Under the vibration drive of the vibration motor body 15, the sand and gravel are bounced and filtered on the surface of the screen 18.

[0033] Driven by vibration, water pulsates to form pulsating water flow. This pulsating water flow moves up and down in the jig box 2, so that the differences in density, particle size and shape of the ore sand can be reflected, thereby realizing the stratification and separation of the ore sand. The ore sand produces impact, loose particles, reduces adhesion, accelerates movement and jumping, and under the action of pulsating water flow, the ore sand with small specific gravity moves upward and forward faster with the water flow, while the ore sand with large specific gravity is blocked at the bottom. This process is controlled by adjusting the parameters such as the frequency, stroke and water volume of the pulsating water flow to achieve the best The separation effect is achieved, the adjustment of the vibration motor body 15 is controlled by the logic of the external control cabinet, the fine concentrate passes through the screen 18 into the interior of the pool box 7, and is finally discharged by the fine concentrate discharge valve 9, the middle-layer concentrate enters the interior of the concentrate collection box 10 with the cooperation of the baffle 11, and the upper tailings pass through the tailings discharge port 12 into the interior of the next group of jig boxes 2, and are screened again by the next group of screens 18. In the same way, the fine concentrate discharge valve 9 of the next group will discharge the fine concentrate again, the concentrate collection box 10 of the next group will discharge the middle-layer concentrate, and the tailings of the next group will be discharged. The tailings on the upper layer are discharged from the outlet 12 to carry out multi-stage exciting force driven jigging and re-selection. The cooperation of multiple groups of upper reinforcing rods 13 and lower reinforcing rods 6 increases the structural strength of the jigging box 2 to prevent the jigging box 2 from structural deformation under the vibration drive when too much ore is put in. When vibrating, the existing vibration motor is used as the power source. A higher driving frequency means higher efficiency. The working frequency can be adjusted, and the driving force angle can be adjusted. Therefore, it can be reasonably adjusted according to different ore dressing property requirements to ensure that the jigging and re-selection of the mineral achieves the best effect and improves the extraction of concentrate. The machine can take the maximum amount of ore and reduce the proportion of tailings. The driving method is simple. The vibration motor is mounted on the top, which avoids the contact between the vibration motor and ore or water, prevents the vibration motor from being damaged by collision or water immersion, facilitates the maintenance of the vibration motor, and prolongs the service life of the exciting force driven jig. It realizes the multi-stage and efficient gravity separation of the vibration motor mounted on the exciting force driven jig, facilitates the maximum extraction of fine concentrate and middle-layer concentrate, reduces the discharge of tailings, and has a simple and efficient driving method, which reduces the later maintenance and use costs and prolongs the service life of the exciting force driven jig.

[0037] When it is necessary to clean the ore sand embedded in the screen 18, the multiple groups of servo motors 23 are turned on. Under the support of the positioning frame 22, the servo motor 23 drives the disc 30 to rotate through the rotating shaft 24, and the disc 30 drives the positioning shaft 25 to rotate.
