Description

Technical Field

[0001] The utility model relates to the field of coal flotation, in particular to a flotation device used in coal mining. Background Art

[0002] Flotation coal selection is the separation of coal and gangue particles based on their different surface properties. Flotation is the separation process based on the differences in the surface physical and chemical properties of coal and mineral impurities. In order to enhance the separation effect, various flotation agents are added during flotation. Flotation agents are a general term for various chemical agents used to achieve or promote flotation. Useful minerals and waste residues can be efficiently separated through flotation.

[0003] At present, in the process of flotation of coal ore, the floating ore cannot be cleaned in time, which affects the floating and sinking speed of the subsequently added coal ore and affects the efficiency of flotation of coal ore. Utility Model Content

[0005] The technical implementation scheme of the utility model is: a flotation device for coal mining, including a material frame, a sealing door is installed on one side of the material frame, a flotation frame is installed on the other side of the material frame, the flotation frame is connected to the material frame, two discharge hoppers are installed on the outer side of the flotation frame, the two discharge hoppers are symmetrically arranged, and a salvage mechanism is provided on the flotation frame.

[0006] In addition, it is particularly preferred that the salvage mechanism includes a slide rail, two of the slide rails are installed on the flotation frame, the two slide rails are symmetrically arranged, both of the slide rails are slidably connected to an electric slider, and a salvage net is rotatably connected between the two electric sliders.

[0011] Beneficial effects: 1. The utility model contacts the rack on one side through the column gear, and the column gear will rotate. The rotation of the column gear will drive the salvage mesh plate to flip. After the salvage mesh plate is tilted, the coal ore on the salvage mesh plate will be discharged into the discharge hopper along the salvage mesh plate. This can be repeated to continuously salvage the coal ore floating in the flotation frame, reduce the amount of coal ore accumulated in the flotation frame, and will not affect the floating and sinking of the coal ore added subsequently.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: A flotation device for coal mining, such as Figure 1-Figure 6 As shown, it includes a material frame 1, a sealing door 2 is installed on one side of the material frame 1, a flotation frame 3 is installed on the other side of the material frame 1, the flotation frame 3 is connected to the material frame 1, two discharge hoppers 4 are installed on the outer side of the flotation frame 3, the two discharge hoppers 4 are symmetrically arranged, and the flotation frame 3 is provided with a salvage mechanism for salvaging the floating coal ore.

[0022] The salvage mechanism includes a slide rail 5. Two slide rails 5 are installed on the flotation frame 3 by bolts. The two slide rails 5 are symmetrically arranged. Electric sliders 6 are slidably connected to the two slide rails 5. A salvage mesh plate 7 is rotatably connected between the two electric sliders 6. The salvage mesh plate 7 is used to salvage the floating coal ore.

[0023] The bottom surface of the discharge hopper 4 is inclined, and the discharge hopper 4 can discharge the coal ore therein more quickly.

[0024] The salvaging mechanism also includes a column gear 8, and the column gears 8 are installed on both ends of the salvaging net plate 7 in a key connection manner. Two racks 9 are respectively installed on the two slide rails 5 by bolts, and the column gear 8 will mesh with the rack 9 on the same slide rail 5.

[0025] The operator first pours an appropriate amount of flotation agent into the material frame 1 and the flotation frame 3, and then the operator continuously discharges coal ore into the flotation frame 3. Under the action of the flotation agent, the heavier coal ore will fall down into the material frame 1, and the lighter coal ore will float on the upper part of the flotation frame 3. Then the operator starts the electric slider 6, which will slide along the slide rail 5. The electric slider 6 will move with the salvage mesh plate 7 and the column gear 8. The salvage mesh plate 7 will push the floating coal ore to move. When the column gear 8 moves, the float The rack 9 on one side of the selection frame 3 will drive the column gear 8 and the salvage mesh plate 7 to rotate a certain angle, so that the salvage mesh plate 7 rotates to a vertical state, which is convenient for the salvage mesh plate 7 to salvage the floating coal ore. Then the column gear 8 continues to move and meshes with the rack 9 on the other side of the flotation frame 3. The rack 9 on the other side of the flotation frame 3 drives the column gear 8 and the salvage mesh plate 7 to continue to rotate a certain angle, so that the salvage mesh plate 7 rotates to an inclined state again, and the coal ore on the salvage mesh plate 7 will be discharged along the salvage mesh plate 7 to one of the The coal ore is discharged from the discharge hopper 4, and then the operator adjusts the electric slider 6 to move in the opposite direction, and the electric slider 6 will drive the salvage mesh plate 7 and the column gear 8 to move in the opposite direction, and the rack 9 on the other side of the flotation frame 3 drives the column gear 8 and the salvage mesh plate 7 to rotate in the opposite direction, so that the salvage mesh plate 7 rotates to a vertical state, and the salvage mesh plate 7 continues to push the floating coal ore to move, and then the rack 9 on one side of the flotation frame 3 drives the column gear 8 and the salvage mesh plate 7 to continue to rotate in the opposite direction to a tilted state, and the salvage mesh plate 7 is rotated to a vertical state. The coal ore picked up by the plate 7 will be discharged into another discharge hopper 4 along the salvage mesh plate 7, and this process is repeated to continuously salvage the coal ore floating in the flotation frame 3, thereby reducing the amount of coal ore accumulation floating in the flotation frame 3, and will not affect the floating and sinking of the coal ore added subsequently. After completing the flotation, the operator closes the electric slider 6, then opens the valve to discharge the flotation agent in the material frame 1 and the flotation frame 3, and finally opens the sealing door 2 to take out the coal ore that has sunk to the bottom, and then closes the sealing door 2.

[0026] Embodiment 2: Based on embodiment 1, Figure 4-Figure 6 As shown, the salvage mechanism also includes an arc-shaped partition 10, and the arc-shaped partition 10 is fixedly connected to both side surfaces of the flotation frame 3. A sliding frame 11 is slidably installed between the two arc-shaped partitions 10, and a plurality of moving frames 12 for moving coal ore are slidably installed on the sliding frame 11.

[0027] The salvage mechanism also includes a reset spring 13 , and the reset spring 13 is connected between each of the toggle frames 12 and the sliding frame 11 . A plurality of arc blocks 14 are welded on the other two side surfaces of the flotation frame 3 , and the arc blocks 14 are in contact with the toggle frames 12 .

[0028] When the salvage mesh 7 swings, one side of the salvage mesh 7 will contact one of the arc partitions 10, thereby reducing the probability of the coal ore slipping during the salvage process. When the salvage mesh 7 swings and contacts one side of the sliding frame 11, the sliding frame 11 will drive the toggle frame 12 to move in the direction of the salvage mesh 7 swinging, and the toggle frame 12 can toggle the bottom of the coal ore floating in the flotation frame 3, thereby reducing the sedimentation of the coal ore floating in the flotation frame 3, accelerating the stratification speed of the coal ore in the flotation frame 3, and improving the flotation efficiency.

[0029] When the sliding frame 11 drives the toggle frame 12 to move together, the bottom of the toggle frame 12 will contact the arc block 14, and the arc block 14 will squeeze the toggle frame 12 to move upward, and the return spring 13 will be compressed. When the bottom of the toggle frame 12 is separated from the arc block 14, the toggle frame 12 will move downward under the action of the return spring 13, and this process is repeated. The toggle frame 12 can move up and down to poke the bottom of the floating coal ore in the flotation frame 3, thereby further accelerating the stratification speed of the coal ore in the flotation frame 3 and further improving the flotation efficiency.
