Description

Technical Field

[0001] This utility model relates to the field of flotation equipment technology, and in particular to a flotation machine for pretreatment of muddy ore. Background Technology

[0002] The working principle of flotation machine for pretreatment of muddy minerals is mainly based on the flotation properties of mineral particles. Specifically, the flotation machine injects muddy mineral slurry into the flotation cell through the feed pipe, and then uses a rotating impeller or agitator to generate vigorous agitation, so that the flotation agent and muddy mineral slurry are fully mixed. Next, gas is injected into the flotation cell to form bubbles. These bubbles carry mineral particles to the surface and are eventually collected in the froth layer of the flotation cell. Through this process, the separation of mineral particles from gangue or other impurities is achieved.

[0003] For example, patent CN218654949U discloses a flotation machine, including a casing. A drive motor and a drive shaft are installed at the top of the casing, and the transmission output end of the drive motor is connected to the drive shaft. A protective frame is fixedly connected to the upper surface of the casing. Sound-absorbing cotton pads are adhered to the inner wall of the protective frame. Air inlets are provided on both side walls of the protective frame. Dustproof components are detachably connected to the air inlets of the protective frame. A cover plate is detachably connected to the top opening of the protective frame. Appropriate air volume allows mineral particles to better contact with air bubbles, thereby improving mineral processing efficiency and reducing mineral loss. Although this device achieves the injection of air into the muddy slurry, it has limitations. It cannot control the amount of air injected according to specific conditions, which can easily lead to over-aeration, increasing energy consumption and reducing flotation efficiency and mineral separation efficiency.

[0004] Therefore, in order to solve such problems, we propose a flotation machine for pretreatment of muddy ore. Utility Model Content

[0026] Reference Figure 1-6This utility model provides an embodiment of a flotation machine for pretreatment of muddy ore, including a flotation cell 1. A crossbeam 2 is movably arranged above the flotation cell 1. A flotation machine shaft 3 is rotatably arranged inside the crossbeam 2 via bearings. A drive assembly 4 is fixedly connected to the upper end of the flotation machine shaft 3. The lower end of the flotation machine shaft 3 extends into the flotation cell 1, and an impeller 5 is fixedly arranged at the lower end of the flotation machine shaft 3. A central cylinder 6 is sleeved on the outside of the flotation machine shaft 3. An air inlet pipe 10 is fixedly arranged through the side wall of the central cylinder 6. The upper end of the central cylinder 6 is fixedly installed at the bottom of the crossbeam 2. An air chamber 7 is fixedly connected to the lower end of the central cylinder 6. A cover plate 8 is fixedly connected to the bottom of the air chamber 7. A through hole 81 is fixedly arranged through the upper surface of the cover plate 8. The cover plate 8 is fixedly covered outside the impeller 5. The flotation machine shaft 3 rotates through the air chamber 7 and the cover plate 8. The drive assembly 4 drives the flotation machine shaft 3 to rotate, and the drive impeller 5 rotates to create a negative pressure inside the cover plate 8. This causes air to enter the cover plate 8 through the air inlet pipe 10, the central cylinder 6, and the air chamber 7. The air mixes with the mud minerals entering the cover plate 8 through the through hole 81, forming bubbles. The bubbles carry mineral particles to the surface and are eventually collected. The air chamber 7 is equipped with a control assembly 9, which controls the air flow rate to match the amount of aeration with the amount of mud minerals injected, ensuring an appropriate aeration amount. The control assembly 9 includes a circular basin 91 that is sleeved on the outside of the flotation machine shaft 3 via bearings. The upper end of the circular basin 91 is fixedly installed on the top wall inside the air chamber 7, and the side walls of the circular basin 91 are equidistantly perforated. There are several vent holes 92. A circular ring 93 is movably installed on the top of the inner bottom wall of the circular basin 91. The outer diameter of the circular ring 93 is smaller than the inner diameter of the circular basin 91. A baffle 94 is fixedly installed on the outer side of the circular ring 93, corresponding to the vent holes 92 one by one. The baffle 94 is set against the inner side wall of the circular basin 91. A gear rack 95 is fixedly installed on the inner side of the circular ring 93. The gear rack 95 is annular. A gear ring 96 that movably engages with the gear rack 95 is movably installed above the gear rack 95. A lifting component 97 is provided on the outer wall of the flotation machine shaft 3.

When the baffle 94 rotates, the gap between the vent hole 92 and the baffle 94 gradually increases, so that the amount of air passing through also gradually increases. When the baffle 94 coincides with the inner side wall of the circular basin 91, the amount of air passing through the vent hole 92 reaches its maximum. When it is necessary to adjust the amount of air injected, the electric guide rail 972 drives the slider 973 to drive the gear ring 96 to descend until the gear ring 96 and the gear rack 95 mesh with each other. At this time, the flotation machine shaft 3 rotates and drives the gear ring 96 to rotate, so that the gear ring 96 drives the gear rack 95 to rotate, thereby driving the baffle 94 on the ring 93 to rotate, adjusting the size of the vent hole 92, and realizing the control of the amount of air injected.

A telescopic rod 13 is fixedly connected to the output end of the hydraulic cylinder 12. A push plate 14 is fixedly installed on the top of the telescopic rod 13. The top of the push plate 14 is fixedly connected to the bottom of the cross frame 2. The telescopic rod 13 is driven to rise and fall by the hydraulic cylinder 12, which drives the cross frame 2 to move up and down, so that the impeller 5 can rise from the bottom of the flotation cell 1, which facilitates the cleaning of the impeller 5 and the inside of the cover plate 8 and avoids blockage.

[0028] The top of the support frame 11 is provided with a slot, and the bottom of the cross frame 2 is fixedly connected with a positioning rod 21. The positioning rod 21 is movably locked inside the slot, and the positioning rod 21 limits the cross frame 2 to ensure the stability of the mechanism on the cross frame 2 during operation.

[0029] A scraper 15 is rotatably mounted on the upper front side inside the flotation cell 1. A placement groove 16 is fixedly installed on the side of the flotation cell 1 near the scraper 15. The scraper 15 rotates to push the foam on the upper side inside the flotation cell 1 into the placement groove 16. An arc-shaped plate is fixedly mounted on the top of the side of the placement groove 16 away from the flotation cell 1. The arc-shaped plate prevents the foam from splashing when the scraper 15 scrapes it out, and the splashed foam falls down and causes waste.

[0030] A water supply pipe 17 is fixedly installed on the upper rear side of the inside of the flotation cell 1. The water supply pipe 17 can add water into the flotation cell 1. A high-pressure nozzle 18 is fixedly installed on the outer wall of the water supply pipe 17. The high-pressure nozzle 18 works in conjunction with the hydraulic cylinder 12. When the hydraulic cylinder 12 drives the impeller 5 to rise, the impeller 5 and the cover plate 8 are washed by the high-pressure nozzle 18.

[0031] The drive assembly 4 includes a pulley 41 fixedly sleeved on the outside of the flotation machine shaft 3. A pulley 42 is movably arranged on one side of the pulley 41.

A motor 45 is fixedly connected to the lower end of the rotating shaft 44. The motor 45 is fixedly arranged inside the cross frame 2. The motor 45 drives the rotating shaft 44 to drive the pulley 42 to rotate, so that the pulley 42 drives the pulley 41 to rotate through the belt 43, and finally drives the flotation machine shaft 3 to rotate.

[0032] The inner bottom wall of the circular basin 91 is provided with a track 911. The track 911 is circular. A movable block 931 is fixedly provided at the bottom of the circular ring 93. The movable block 931 is movably provided inside the track 911. When the circular ring 93 rotates, the movable block 931 moves along the track 911, making the movement of the baffle 94 on the circular ring 93 more stable.

[0033] Working principle: The muddy ore is transported to the flotation cell 1, flotation reagents are added, and the motor 45 is started to drive the rotating shaft 44 to drive the pulley 42 to rotate. The pulley 42 drives the pulley 41 to rotate through the belt 43, which drives the flotation machine shaft 3 to rotate. This drives the impeller 5 to rotate, creating a negative pressure inside the cover plate 8. Air enters the cover plate 8 through the air inlet pipe 10, the central cylinder 6, and the air chamber 7. At this time, the electric guide rail 972 drives the slider 973 to drive the gear ring 96 to descend until the gear ring 96 meshes with the gear rack 95. Then, the flotation machine shaft 3 rotates, driving the gear ring 96 to rotate. This drives the gear rack 95 to rotate, thereby driving the baffle 94 on the ring 93 to rotate. The size of the air vent 92 is adjusted to control the amount of air injected. The air mixes with the muddy ore that enters the cover plate 8 through the through hole 81, forming bubbles that rise to the surface and are finally pushed into the placement tank 16 by the scraper 15.
