Description

Technical Field

[0001] The invention relates to the technical field of coal mine flotation, and in particular to a coal mine flotation device and method with uniform quantitative feeding. Background Art

[0002] Coal flotation is a mineral processing method that uses the difference in physical and chemical properties of the surfaces of coal particles and gangue particles to achieve separation. During the flotation process, coal particles have hydrophobic properties, while gangue particles have hydrophilic properties. In the aerated slurry, coal particles will adhere to the bubbles and float up with them, thereby achieving the purpose of separation from the gangue. The flotation process mainly occurs at the interface of solid, liquid and gas. Coal particles will adhere to the bubbles and float up with them due to their hydrophobic properties, while gangue particles will remain in the slurry due to their hydrophilic properties. In this way, the separation of coal and gangue can be achieved. Flotation agents are used in the flotation process of coal mines. Flotation agents are used to adjust the physical and chemical properties of minerals, better sort the minerals, and achieve a higher recovery rate.

[0003] At present, when adding ore particles to coal flotation, the ore particles are placed in a storage frame and are fed into a designated emulsification tank through a feeding pipe by a screw.

[0009] In a preferred solution, both sides of the tooling feeding frame are connected with placement rods by bolts, and two smooth holes are provided on the two placement rods, and the interiors of the two smooth holes are slidably connected with limiting cylinders, one side of the limiting cylinder is fixedly connected to one side of the connecting rod, and the placement rod and the opposite side of the connecting rod are fixedly connected with the same reset spring, and the reset spring is located on the outside of the limiting cylinder, and the sides of the two limiting cylinders facing the flotation support platform are fixedly connected with linkage gear rods, and circular holes three are provided on both sides of the two placement rods, and the interiors of the two circular holes three located on the same side are connected to the same rotating shaft through bearings, and the outsides of the two rotating shafts are fixedly connected with notched gears two, and the tooth block end of the notched gear two is meshed with the linkage gear rod.

[0010] In a preferred solution, circular holes four are provided on both sides of the tooling feeding frame, and the interiors of the two circular holes three are connected to the same linkage round rod through bearings, turntables are fixedly connected to both sides of the linkage round rod and one side of the rotating shaft, the interiors of the two turntables on the same side are slidably connected to the same belt two, one side of the tooling feeding frame is fixedly connected to a universal motor, the driving end of the universal motor and the outside of the linkage round rod are fixedly connected with pulleys, and the outsides of the two pulleys are slidably connected to the same belt one.

[0011] By providing a feeding module, during the flotation process, the ore particles are first poured into the feeding frame, and the servo motor is started to drive the spiral feeding block on the rotating cylinder to feed the ore particles. At this time, the ore particles fall into the feeding trough on the quantitative feeding plate, and the weighing device located below the feeding trough weighs the ore particles. When the feeding standard is reached, the servo motor stops rotating to feed the ore particles, and the drive motor 1 is started to rotate the notched gear 1. When the tooth block end of the notched gear 1 is engaged with the linkage gear, the pushing cylinder is driven to rotate the quantitative feeding plate in the limit mounting frame, so that the filled feeding trough moves to the top of the feeding circular tube, and the weighed ore particles are fed. At this time, a continuous operation is formed, and the feeding circular tube feeds the ore particles. When unloading, the universal motor is started to drive the linkage round rod to rotate the turntables on both sides, thereby driving the notched gear 2 on the rotating shaft to rotate. When the tooth block end of the notched gear 2 is meshed with the linkage gear rod, the linkage gear rod drives the connecting rod on the limit cylinder to move downward. At this time, the reset spring is squeezed. When the notched gear 2 is separated from the linkage gear rod, the connecting rod rebounds quickly to make the top rod on the lifting slide vibrate up and down in the feeding round tube to avoid blockage of the ore particles during feeding. Through the feeding module, during the flotation process, it is avoided to feed too much ore particles at one time. By uniformly and quantitatively feeding the ore particles, the ore particles can be evenly and fully mixed with the flotation agent during the flotation process, thereby improving the flotation effect of the coal mine.

[0013] In a preferred embodiment, the outside of the hollow rotating tube is fixedly connected with a rotating push rod, and a sliding groove is provided on the side of the rotating push rod, and a hollow sliding frame is slidably connected inside the sliding groove, and a circular hole seven is provided on the side of the hollow sliding frame facing the sealing cover plate, and the inside of the circular hole seven is connected with a rotating shaft one through a bearing, and a circular hole eight is provided on the side of the rotating push rod, and the inside of the circular hole eight is connected with a rotating shaft two through a bearing, and the outside of the rotating shaft two is respectively fixedly connected with an adjusting gear and a deflection block, and the adjusting gear is meshed with a limiting round gear frame, and a circular hole nine is provided on one side of the deflection block, and the inside of the circular hole nine is connected with an eccentric shaft through a bearing, and the eccentric shaft is movably connected to the outside of the rotating shaft one. It is connected to the same reciprocating push rod, and a conveying port is provided on the side of the hollow sliding frame facing the inside of the emulsification tank. The inside of the conveying port is fixedly connected to a hollow fixed rod, and a stirrer is evenly connected to both sides of the hollow fixed rod through bolts. Installation ports are evenly provided on both sides of the hollow fixed rod, and nozzles are fixedly connected to the insides of multiple installation ports. A driving motor 2 is fixedly connected to the sealing cover plate, and a pulley 2 is fixedly connected to the outside of the driving motor 2 and the hollow rotating tube. The outsides of the two pulleys 2 are slidably connected to the same belt 3. A connecting hole is provided on one side of the hollow rotating tube and the hollow sliding frame, and the insides of the two connecting holes are fixedly connected to the same metal telescopic tube.

[0014] By providing a mixing module, during the process of feeding the ore particles, flotation reagents are added to the emulsification tank. At this time, the flotation reagents are filled into the conveying pipe through the liquid inlet pipe and then enter the hollow rotating pipe and then into the hollow sliding frame, so that the multiple nozzles on the hollow fixed rod blow the flotation reagents into the emulsification tank, and at the same time, the driving motor 2 is started, so that the hollow rotating tube drives the rotating push rod to rotate in a circle. The rotating push rod rotates in a circle and the adjusting gear at the top thereof rotates under the limit of the limit spherical gear frame, so that the deflection block drives the reciprocating push rod to drive the hollow sliding frame to move horizontally in the slide groove on the rotating push rod, so that when the flotation reagents are added evenly, the agitator stirs the mixed ore pulp evenly to generate bubbles. After the flotation reagents are added, the gas is filled into the conveying pipe through the air inlet pipe, and the above operation is repeated to blow the gas into the ore pulp, accelerate the generation of bubbles, and accelerate the flotation effect of the mineral.

[0016] By arranging a processing support rod, an extrusion spring and a cleaning soft plate, when the rotating push rod rotates, the extrusion spring on the processing support rod makes the cleaning soft plate fit the inner wall of the milk ring tank through its own elasticity, so as to scrape off the minerals attached to the inner wall of the emulsification tank.

[0017] A method for using a coal mine flotation device with uniform quantitative feeding, using the coal mine flotation device with uniform quantitative feeding as described above, comprises the following steps: Step 1: During the flotation process, first pour the ore particles into the feeding frame. Then start the servo motor to drive the spiral feeding block on the rotating cylinder to feed the ore particles. At this time, the ore particles fall into the feeding trough on the quantitative feeding plate. At the same time, the weighing device located below the feeding trough weighs the ore particles. Step 2: When the feeding standard is reached, the servo motor stops rotating to discharge the ore particles, and the drive motor 1 is started to rotate the notch gear 1. When the tooth block end of the notch gear 1 is meshed with the linkage gear, the cylinder is driven to rotate the quantitative feeding plate in the limit installation frame, so that the filled feeding trough moves to the top of the feeding tube, and the weighed ore particles are discharged, forming a continuous operation; Step three, when the feeding tube is feeding the ore particles, the universal motor is started to drive the linkage round rod to rotate the turntables on both sides, thereby driving the notched gear 2 on the rotating shaft to rotate. When the tooth block end of the notched gear 2 is engaged with the linkage gear rod, the linkage gear rod drives the connecting rod on the limit cylinder to move downward. At this time, the reset spring is squeezed. When the notched gear 2 is separated from the linkage gear rod, the connecting rod rebounds quickly, causing the top rod on the lifting slider to vibrate up and down in the feeding tube.

[0018] From the above, it can be seen that the coal flotation equipment with uniform quantitative feeding provided by the present invention can avoid excessive one-time feeding of ore particles during the flotation process. By uniformly and quantitatively feeding the ore particles, the ore particles can be evenly and fully mixed with the flotation agent during the flotation process, thereby improving the beneficial effect of coal flotation.

When the tooth block end of the notched gear 2 434 is engaged with the linkage gear rod 432, the linkage gear rod 432 drives the connecting rod 428 on the limiting cylinder 431 to move downward. At this time, the reset spring 430 is squeezed. When the notched gear 2 434 is separated from the linkage gear rod 432, the connecting rod 428 rebounds rapidly, causing the top rod 427 on the lifting slider 425 to vibrate up and down in the feeding tube 422.

[0036] Working principle: During the flotation process, firstly, the ore particles are poured into the feeding frame 410. At this time, the servo motor 412 is started to drive the spiral feeding block 415 on the rotating cylinder 413 to feed the ore particles. At this time, the ore particles fall into the feeding trough on the quantitative feeding plate 402. At the same time, the weighing device 416 located below the feeding trough weighs the ore particles. When the feeding standard is reached, the servo motor 412 stops rotating to feed the ore particles. At the same time, the drive motor 1 407 is started to rotate the notch gear 1 408. When the tooth block end of the notch gear 1 408 meshes with the linkage gear 406, the cylinder 405 is driven to make the quantitative feeding plate 402 in the limit installation frame 403. The feeding trough is rotated so that the filled feeding trough moves to the top of the feeding circular tube 422, and the weighed ore particles are discharged. At this time, continuous operation is formed. When the feeding circular tube 422 discharges the ore particles, the universal motor 419 is started to drive the linkage circular rod 417 to rotate the turntables 420 on both sides, thereby driving the notched gear 2 434 on the rotating shaft 433 to rotate. When the tooth block end of the notched gear 2 434 is engaged with the linkage gear rod 432, the linkage gear rod 432 drives the connecting rod 428 on the limiting cylinder 431 to move downward. At this time, the reset spring 430 is squeezed. When the notched gear 2 434 is separated from the linkage gear rod 432, the connecting rod 428 rebounds quickly. The top rod 427 on the lifting slider 425 vibrates up and down in the feeding tube 422. When the ore particles enter the emulsification tank 501, a flotation agent is added to the emulsification tank 501. At this time, the flotation agent is filled into the conveying pipe 505 through the liquid inlet pipe 507 and enters the hollow rotating pipe 511 and then enters the hollow sliding frame 517, so that the multiple nozzles 516 on the hollow fixed rod 514 blow the flotation agent into the emulsification tank 501. At the same time, the driving motor 509 is started, so that the hollow rotating pipe 511 drives the rotating push rod 512 to rotate in a circle. The rotating push rod 512 rotates in a circle. At the same time, the adjusting gear 521 at the top of the rotating push rod 512 is automatically moved under the limit of the limit scallop frame 513. The deflection block 522 drives the reciprocating push rod 519 to drive the hollow slide frame 517 to move horizontally in the slide groove on the rotating push rod 512, so that when the flotation reagent is added evenly, the stirrer 515 can evenly stir the mixed slurry to generate bubbles. After the flotation reagent is added, the gas is filled into the delivery pipe 505 through the air inlet pipe 506, and the above operation is repeated to make the gas blow into the slurry to accelerate the generation of bubbles. When the rotating push rod 512 rotates, the extrusion spring 8 on the processing support rod 7 makes the cleaning soft plate 9 fit the inner wall of the emulsification tank 501 through its own elasticity, so as to scrape off the minerals attached to the inner wall of the emulsification tank 501.
