Description

Technical Field

[0001] The utility model belongs to the technical field of flotation equipment, in particular to a bubble pushing mechanism of a flotation machine. Background Art

[0002] Flotation technology, which utilizes differences in the physical and chemical properties of mineral surfaces to separate mineral particles, is currently the most widely used mineral processing method. It uses surfactants and frothers to form bubbles. The action of a collector causes mineral particles to adhere to the bubbles and rise in the slurry. Once a foam layer forms on the slurry surface, the bubbles are pushed out of the flotation machine and collected.

[0003] A Chinese patent document with authorization publication number CN216296685U discloses a reciprocating automatic lifting flotation machine bubble pushing mechanism. The mechanism automatically lifts and lowers a bubble pushing plate, enabling the bubble pushing device to contact the foam layer during the pushing stroke and not during the return stroke. This avoids unnecessary disturbance of the foam layer by the bubble pushing plate during the return stroke, contributes to the stability of the foam layer, and allows for timely and efficient discharge of flotation foam, effectively reducing reagent loss.

[0004] However, in the prior art, the bubble pushing mechanism is inconvenient to flexibly adjust the height of the component that can push out the foam layer to adapt to the foam layer with a changed height. Therefore, a bubble pushing mechanism for a flotation machine is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a bubble pushing mechanism for a flotation machine.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A flotation machine bubble pushing mechanism includes a flotation cell capable of accommodating a slurry that continuously generates bubbles. A bubble pushing assembly is provided above the flotation cell, capable of flexibly adjusting the bubble pushing height of the mechanism according to the height of the bubbles. A bubble blowing assembly is provided on the bubble pushing assembly to prevent insufficient bubble pushing.

[0008] The bubble pushing component includes a longitudinal moving part that enables the mechanism to push bubbles in different directions, a bubble pushing part that can push bubbles out at different angles, and a lifting part that enables the bubble pushing part to move at different heights along with the longitudinal moving part.

[0009] Preferably: the longitudinal moving part includes a carrier fixedly installed on the flotation tank, with supports fixedly installed in front and rear of the carrier, a bidirectional screw movably connected between the supports, a motor fixedly connected to the rear end of the bidirectional screw, support rods provided on both sides of the bidirectional screw, and a longitudinal moving frame provided between the bidirectional screw and the support rods.

[0012] Preferably, the support is rotatably connected to the bidirectional lead screw, the bidirectional lead screw is threadedly connected to the longitudinal frame, and the support rod is slidably connected to the longitudinal frame.

[0013] Preferably, the lifting frame is rotatably connected to the bubble pushing plate, and both the lifting frame and the bubble pushing plate are rotatably connected to the cylinder.

[0014] The beneficial effects of the utility model are as follows: in the process of the longitudinal moving member driving the bubble pushing member to move back and forth above the ore pulp in the flotation tank, the height of the bubble pushing member with a variable inclination is adjusted by the lifting member, and combined with the blowing action of the bubble blowing component on the bubbles, the bubbles floating out of the ore pulp can be fully pushed out of the flotation tank. At the same time, when the bubble pushing member is reset, it is prevented from bringing the bubbles that have been pushed to the edge of the flotation tank back to the middle area of ​​the flotation tank.

[0024] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.

[0025] like Figure 1-Figure 4 As shown, a flotation machine bubble pushing mechanism includes a flotation cell 1 that can accommodate mineral slurry that continuously generates bubbles. A bubble pushing component 2 is provided above the flotation cell 1 and can flexibly adjust the bubble pushing height of the mechanism according to the height of the bubbles. A bubble blowing component 3 is provided on the bubble pushing component 2 to avoid insufficient bubble pushing.

[0026] In this embodiment: the bubble pushing component 2 includes a longitudinal moving part that can enable the mechanism to push bubbles in different directions, a bubble pushing part that can push bubbles out at different angles, and a lifting part that can enable the bubble pushing part to move at different heights with the longitudinal moving part. The longitudinal moving part includes a carrier 201 fixedly mounted on the flotation tank 1, and supports 202 are fixedly mounted on the front and rear of the carrier 201. A bidirectional screw 203 is movably connected between the supports 202, and a motor 204 is fixedly connected to the rear end of the bidirectional screw 203. Support rods 205 are provided on both sides of the bidirectional screw 203. A longitudinal moving frame 206 is provided between the bidirectional screw 203 and the support rod 205. The lifting part includes a hydraulic rod 207 fixedly mounted on the longitudinal moving frame 206, and a lifting frame 208 is fixedly connected between the telescopic ends of the hydraulic rods 207 in the same longitudinal position. The bubble pushing part includes a bubble pushing plate 209 movably connected to the lifting frame 208, and a cylinder 210 is provided between the lifting frame 208 and the bubble pushing plate 209;

[0027] The support 202 is rotatably connected to the bidirectional screw 203, the bidirectional screw 203 is threadedly connected to the longitudinal frame 206, the support rod 205 is slidably connected to the longitudinal frame 206, the lifting frame 208 is rotatably connected to the bubble pushing plate 209, and the lifting frame 208 and the bubble pushing plate 209 are both rotatably connected to the cylinder 210;

[0028] The support 202, support rod 205 and other components are installed through the carrier 201, and the bidirectional screw 203 is driven by the motor 204 to rotate relative to the support 202. The rotated bidirectional screw 203 drives the longitudinal movement frame 206 and the components thereon to move longitudinally. The support rod 205 is used to improve the stability of the longitudinal movement of the longitudinal movement frame 206. The height of the lifting frame 208 equipped with the bubble pushing plate 209 and the cylinder 210 is adjusted by the hydraulic rod 207. The bubble pushing plate 209 is driven to rotate relative to the lifting frame 208 by the cylinder 210 to adjust the inclination of the bubble pushing plate 209.

[0029] In this embodiment, the bubble blowing assembly 3 includes tube clamps 301 fixedly mounted on both sides of the carrier 201, a nozzle 302 is provided between the tube clamps 301, a nozzle 303 is fixedly connected to the outer side of the nozzle 302, and a connector 304 is fixedly connected to one side of the nozzle 302;

[0030] The nozzle 302 is installed in the carrier 201 with the nozzle 303 facing downwards through the pipe clamp 301 , and the nozzle 302 is easily connected to the air supply equipment through the joint 304 .

[0031] Working Principle: When the bubble pushing mechanism is installed and used in a flotation machine, the joint 304 is connected to the air supply equipment so that the nozzle 303 can continuously blow air downward to push the bubbles floating on the surface of the slurry in the flotation cell 1 from the middle area to the front and rear areas of the flotation cell 1;

[0032] On this basis, the bubble pushing plate 209 can be indirectly driven to move forward and backward above the slurry by the forward and reverse rotation of a certain frequency at the output end of the motor 204, so that the bubble pushing plate 209 can push the bubbles out of the flotation tank 1 after contacting the bubbles.

[0033] In order to improve the degree of bubble pushing, when the bubble pushing plate 209 moves from the middle area of ​​the flotation tank 1 to the front and rear edges, the height of the bubble pushing plate 209 can be adjusted by the hydraulic rod 207, and the inclination of the bubble pushing plate 209 can be adjusted by the cylinder 210, so that the bubble pushing plate 209 can be in a vertical state and push the bubbles outward at an appropriate height to fully contact and push out the bubbles, and the bubble pushing plate 209 can be in a horizontal state when it is reset to the middle area of ​​the flotation tank 1 to avoid pushing the bubbles from the edge of the flotation tank 1 back to the middle area.

[0034] The preferred embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of technicians in the relevant technical field without departing from the purpose of the present invention.
