The invention drives a sealing gasket to block the ports of a receiving shell and a mounting shell through a side plate, so that a closed structure is formed at the connection between the two. A fixed rod drives a baffle to slide outwards on the inner wall of a sliding groove, so that the baffle is opened, and sediments in the inner cavity of the mounting shell are sunk to the bottom. When a set time parameter is reached, the baffle is closed to separate the flotation liquid and sediments in the inner cavity of the mounting shell. Only the side plate needs to be opened, and the sediments will slide into the inner cavity of the receiving shell along a guide block for collection. A floating ring is pushed by gas to slide downward on the inner wall of a through pipe. When the floating ring moves to one side of a ventilation groove, the gas is released through the ventilation groove. When the device is closed, the floating ring loses air pressure, and moves to the other side of the ventilation groove on the buoyancy of the liquid. The device is automatically closed, so that mud is prevented from entering and blocking the air pipe.

Description

Technical Field

[0001] The present invention relates to the technical field of copper-molybdenum ore dressing and flotation, and in particular to flotation equipment used for copper-molybdenum ore dressing and a method of using the same. Background Art

[0002] The main method for beneficiation of copper-molybdenum minerals is flotation. When deep selecting ores mainly composed of molybdenum and containing trace copper, a partial mixed priority flotation process is adopted. The process of molybdenum-copper mixed flotation, tailings flotation pyrite, copper-molybdenum separation and partial mixed-priority flotation of molybdenum concentrate is adopted. The commonly used process is copper-molybdenum mixed flotation, and then copper-molybdenum separation and molybdenum concentrate selection; Among them, copper ore beneficiation mechanical flotation machinery: The flotation machinery commonly used for copper ore selection is the flotation machine, and the commonly used ones are xjk type flotation machine, Sf type flotation machine, etc. The mechanical stirring flotation machine is a stirring self-priming flotation machine. The stirring self-priming flotation machine stirs the slurry by rotating impellers, uses the locally formed negative pressure zone, inhales air from the atmosphere outside the tank, and generates bubbles by turbulent crushing action.

[0003] The grinding products of copper-molybdenum minerals are sent to the hydrocyclone for classification, the bottom flow of the classifier returns to the ball mill for re-grinding, and the overflow is transported to the mixing tank by a pipeline for mixing. After mixing, the slurry enters the flotation machine for flotation. After the slurry passes through the copper roughing selection once, the tailings are scavenged, and the scavenged concentrate is returned to the copper roughing selection for re-selection. However, after the existing flotation machine flotates the copper-molybdenum minerals, the tailings with more impurities are collected and then ground for multiple flotation. However, if the tailings slurry is discharged using a slurry pipe, the slurry discharge will also bring out the mixed liquid in the flotation tank, and the flotation liquid needs to be continuously injected. The slurry in the corners is also not completely discharged, and the flotation liquid needs to use reagents. , its reagents cause certain pollution to the environment, how to reduce the consumption of flotation liquid and discharge the tailings slurry in time, and most of the existing flotation machines use stirring to generate bubbles, but the number of bubbles generated by this method is not easy to control, and the effect of the generated bubbles is not good. The sediments around cannot be stirred, which will affect the flotation effect and cause the problem of low flotation efficiency. When the air inlet pipe is set in the middle of the flotation tank, the air intake is less and the bubbles generated are less. It is difficult to stir the sediments at the bottom of the flotation tank, and the slurry is easy to block the air inlet pipe, resulting in reduced air intake. Therefore, flotation equipment for copper-molybdenum ore dressing and its use method are needed to improve the above problems. Summary of the invention

[0015] The method for using the flotation equipment for copper-molybdenum ore dressing is as follows:

[0016] Operation step 1: by injecting the mixed flotation liquid into the inner cavity of the liquid inlet pipe, the flotation liquid enters the inner cavity of the fixed cylinder, and then putting the ground copper-molybdenum ore powder into the feed shell to mix it with the flotation liquid, it is only necessary to turn on the switch of the controller, so that the controller controls the driving motor to operate, so that the driving shaft of the driving motor drives the driving wheel to rotate, so that the driving wheel drives the power wheel to rotate through the belt, so that the power wheel drives the rotating shaft to rotate, so that one end of the rotating shaft drives the stirring blade to rotate, so that the stirring blade stirs the mixed slurry at the port of the fixed cylinder and between the stirring blade and the fixed blade to generate bubbles for flotation, and then turn on the switch of the controller, so that the controller controls the motor module to operate, so that the motor module drives the rotating wheel to rotate, so that the rotating wheel drives the driven wheel to rotate through the belt, so that the driven wheel drives the rotating rod to rotate, so that the rotating rod drives the paddle to rotate on the inner wall of the fixed sleeve, so that the paddle paddles the froth of the flotation tank in the inner cavity of the installation shell, so that the froth flows into the inner cavity of the receiving shell for collection;

[0017] Operation step 2: Turn on the switch of the controller so that the controller controls one end of the electric telescopic rod to operate, and at the same time, the electric telescopic rod drives the side plate to slide to one side on the inner wall of the material receiving shell, so that the side plate drives the sealing gasket to block the ports of the material receiving shell and the installation shell, so that the connection between the two forms a closed structure. When there are a lot of flotation sediments in the inner cavity of the installation shell, it is only necessary to turn on the switch of the controller so that the controller controls the operation of the electric hydraulic rod, so that one end of the electric hydraulic rod drives the fixed rod to move to one side, so that the fixed rods on both sides simultaneously drive the inner wall of the baffle to slide outward respectively, so that the baffle is opened, and the sediments in the inner cavity of the installation shell sink to the bottom;

[0018] Operation step three: When the set time parameter is reached, the baffle is closed in the same way as above to separate the flotation liquid and sediment in the inner cavity of the installation shell. Then, only the side plate needs to be opened, and the sediment will slide along the inclined guide block into the inner cavity of the receiving shell for collection;

[0019] Operation step 4: Just connect the connecting pipe to the external high-pressure gas pipeline, open the electric air pressure regulating valve, let the high-pressure gas fill the air pipe, let the high-pressure gas enter the inner cavity of the installation tube through the through pipe, let the space between the floating ring and the installation tube be filled with high-pressure gas, let the gas push the floating ring to move to one side of the ventilation groove through the through pipe, let the gas be released through the ventilation groove, and then the high-pressure gas will pass through the bubble stone to generate a large number of bubbles. When the device is closed, one end of the floating ring loses air pressure, and under the buoyancy of the liquid, the floating ring moves up to the other side of the ventilation groove, so that the device is automatically closed, avoiding the entry of mud to block the air pipe;

[0020] Operation step five: When the stirring blade is stirring, the air stone located below is ventilated to produce bubbles. Since the air stone is located directly below the baffle, the air stone produces a large number of bubbles from the bottom, which blows the sediment around the bottom of the inner cavity of the installation shell, so that the useful minerals in the sediment are further floated.

[0021] Compared with the prior art, the present invention provides a controller in the flotation equipment to control the operation of one end of the electric-controlled telescopic rod, and at the same time, the electric-controlled telescopic rod drives the side plate to slide to one side on the inner wall of the material receiving shell, so that the side plate drives the sealing gasket to block the ports of the material receiving shell and the installation shell, so that the connection between the two forms a closed structure. When there are a lot of flotation sediments in the inner cavity of the installation shell, it is only necessary to turn on the switch of the controller so that the controller controls the operation of the electric-controlled hydraulic rod, so that one end of the electric-controlled hydraulic rod drives the fixed rod to move to one side, so that the fixed rods on both sides simultaneously drive the baffles to slide outward on the inner wall of the sliding groove respectively, so that the baffles are opened, and the sediments in the inner cavity of the installation shell sink to the bottom. When the set time parameter is reached, When the number of times is reached, the baffle is closed by the same reason as above, and the flotation liquid and sediment in the inner cavity of the installation shell are separated. Then, only the side plate needs to be opened, and the sediment will slide into the inner cavity of the receiving shell along the inclined guide block for collection. Compared with the mud pipe, this solution has a better collection effect on the sediment, and tries to avoid the loss of flotation liquid, and does not affect the flotation process, thereby solving the problem that if the ore mud is discharged by the mud pipe, the mud discharge will also bring out the mixed liquid in the flotation tank, and the flotation liquid needs to be continuously injected, and the mud is also not completely discharged for the mud in the corner. In addition, the flotation liquid needs to use reagents, and the reagents have certain pollution to the environment. How to reduce the consumption of flotation liquid and discharge the tailings mud in time.

[0022] High-pressure gas enters the inner cavity of the installation tube through the through pipe, so that the space between the floating ring and the installation tube is filled with high-pressure gas, so that the gas pushes the floating ring to slide downward on the inner wall of the through pipe. When the floating ring moves to one side of the ventilation groove, the gas is released through the ventilation groove, and then the high-pressure gas generates a large number of bubbles through the bubble stone. When the device is closed, one end of the floating ring loses air pressure. Under the buoyancy of the liquid, the floating ring moves up to the other side of the ventilation groove, so that the device automatically closes, avoiding the entry of mud to block the air pipe, and the effect is better, thereby solving the problem that when the air inlet pipe is set in the middle of the flotation tank, the air intake is less and the bubbles generated are less, it is difficult to stir the sediment at the bottom around the flotation tank, and the mud is also easy to block the air inlet pipe, resulting in reduced air intake.

[0023] When the stirring blades are stirring, the air stone located below is ventilated to generate bubbles. Since the air stone is located directly below the baffle, a large number of bubbles are generated from the bottom of the air stone, which can effectively blow the sediments around the bottom of the inner cavity of the installation shell, so that the useful minerals in the sediments are further floated and the effect is better, thereby solving the problem that most existing flotation machines use stirring to generate bubbles, but the number of bubbles generated by this method is not easy to control, and the effect of the bubbles generated is not good. The sediments around cannot be stirred, which will affect the flotation effect and cause low flotation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] An electric telescopic rod 408 is installed on the outer wall of the material receiving shell 406, one end of the electric telescopic rod 408 penetrates the material receiving shell 406 and extends to the inner wall of the material receiving shell 406, and is slidably connected to a side plate 409. Under the action of a sealing gasket 410 installed on the outer wall of the side plate 409, it is only necessary to turn on the switch of the controller 3, so that the controller 3 controls one end of the electric telescopic rod 408 to operate, and at the same time, the electric telescopic rod 408 drives the side plate 409 to slide to one side on the inner wall of the material receiving shell 406, so that the side plate 409 drives the sealing gasket 410 blocks the ports of the receiving shell 406 and the installation shell 1, so that the connection between the two forms a closed structure. At the same time, an electric-controlled hydraulic rod 403 is installed on the outer wall of the fixed bracket 401, and a fixed rod 404 is installed at one end of the electric-controlled hydraulic rod 403. A baffle 405 is installed on the outer wall of the fixed rod 404. The baffle 405 is slidably connected to the inner wall of the sliding groove 24. When there are more flotation sediments in the inner cavity of the installation shell 1, it is only necessary to turn on the switch of the controller 3, so that the controller 3 controls the electric-controlled hydraulic rod 403 to move. The electric hydraulic rod 403 is rotated, so that one end of the electric hydraulic rod 403 drives the fixed rod 404 to move to one side, so that the fixed rods 404 on both sides simultaneously drive the baffles 405 to slide outwards on the inner wall of the sliding groove 24, so that the baffles 405 are opened, so that the sediment in the inner cavity of the installation shell 1 sinks to the bottom. When the set time parameter is reached, the baffles 405 are closed in the same way as above, and the flotation liquid and sediment in the inner cavity of the installation shell 1 are separated. Then, only the side plate 409 needs to be opened, and the sediment will slide into the receiving portion along the inclined guide block 407. The inner cavity of the material shell 406 is used for collection. Compared with the mud pipe, this solution has a better collection effect on the sediment and avoids the loss of flotation liquid as much as possible, without affecting the flotation process, thereby solving the problem that if the ore mud is discharged by the mud pipe, the mud discharge will also bring out the mixed liquid in the flotation tank, and the flotation liquid needs to be continuously injected. The mud is also not completely discharged from the corners. In addition, the flotation liquid needs to use reagents, and the reagents have certain pollution to the environment. How to reduce the consumption of flotation liquid and discharge the tailings mud in time.

[0041] The connecting tube 501 is installed at the port of the connecting hole 23. A one-way valve 503 is installed at one end of the connecting tube 501, and an electric air pressure regulating valve 504 is installed at the other end of the connecting tube 501. Under the action of the air pipe 505 installed on the outer wall of the connecting tube 501, it is only necessary to connect the connecting tube 501 to the external high-pressure gas pipeline, open the electric air pressure regulating valve 504, so that the high-pressure gas fills the air pipe 505, and then a ventilation groove 507 is opened on the outer wall of the installation cylinder 506, and a through pipe 508 is embedded and installed on one side of the ventilation groove 507 and located on the outer wall of the air pipe 505. A floating ring 509 is slidably connected to the outer wall of the through pipe 508. Under the action of a sealing rubber pad 510 installed on the outer wall of the floating ring 509, the high-pressure gas passes through the through pipe 508 and enters the inner cavity of the installation cylinder 506. The gas outlet of the through pipe 508 is located between the floating ring 509 and the installation cylinder 506. Under the action of the inner wall of the mounting tube 506, the space between the floating ring 509 and the mounting tube 506 is filled with high-pressure gas, so that the gas pushes the floating ring 509 to slide downward on the inner wall of the through pipe 508. When the floating ring 509 moves to one side of the ventilation groove 507, the gas is released through the ventilation groove 507, and then the high-pressure gas passes through the bubble stone 502 to generate a large number of bubbles. When the device is closed, one end of the floating ring 509 loses air pressure. Under the buoyancy of the liquid, the floating ring 509 moves up to the other side of the ventilation groove 507, so that the device is automatically closed, avoiding the entry of mud to block the air pipe 505, and the effect is better, thereby solving the problem that when the air inlet pipe is set in the middle of the flotation tank, the air intake is less and the bubbles generated are less, it is difficult to stir the sediment at the bottom around the flotation tank, and the mud is also easy to block the air inlet pipe, resulting in reduced air intake.

[0042] By installing the air stone 502 on the inner wall of the installation shell 1, one end of the air pipe 505 penetrates the air stone 502 and extends to the inner wall of the air stone 502 to install a mounting tube 506, the cross-section of the air stone 502 is a rectangular structure and the air stone 502 is located directly below the fixed blade 20. When the stirring blade 19 is stirring, the air stone 502 located below is ventilated to generate bubbles. Since the air stone 502 is located directly below the baffle 405, the air stone 502 generates a large number of bubbles from the bottom, which can effectively blow the sediment around the bottom of the inner cavity of the installation shell 1, so that the useful minerals in the sediment are further floated and the effect is better, thereby solving the problem that most existing flotation machines use stirring to generate bubbles, but the number of bubbles generated by this method is not easy to control, and the bubble effect generated is not good. The sediment around cannot be stirred, which will affect the flotation effect and cause the flotation efficiency to be low.
