Description

Technical Field

[0001] The utility model relates to the field of automatic ore dressing, in particular to a flotation machine for ore dressing with a self-adaptive exhaust function. Background Art

[0002] Flotation is a technical method for separating useful minerals from ores based on the different physical and chemical properties of the mineral particle surfaces. Flotation is usually carried out in a flotation machine. The slurry treated with reagents is stirred and aerated so that some of the mineral particles are selectively fixed on the bubbles, float to the surface of the slurry, and are scraped out to form a foam product, while the rest are retained in the slurry to achieve the purpose of separating minerals.

[0003] It is difficult to achieve adaptive exhaust in existing flotation machines, which makes it difficult to dynamically adjust bubble generation according to ore demand and changes in the flotation process, reducing ore recovery and increasing tailings losses, which may affect the normal operation of the flotation machine. After adaptive exhaust, it is difficult for existing flotation machines to treat gas, resulting in harmful gases being directly discharged into the environment, causing environmental pollution. In addition, when some equipment uses resin plates to treat gas, the resin plates are usually in a fixed state, and the resin plates will be contaminated due to long-term contact with the gas, reducing the service life of the resin plates. At the same time, it is difficult to ensure that the gas can be effectively adsorbed at any time. Utility Model Content

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The embodiment of the present application discloses a flotation machine for mineral processing with an adaptive exhaust function, wherein an exhaust pipe 2 is fixedly connected to the left side of the front end of the flotation machine 1, an adaptive exhaust mechanism 3 is fixedly connected to the left side of the front end of the flotation machine 1, and a pre-treatment mechanism 4 is fixedly connected to the bottom of the exhaust pipe 2;

[0025] The adaptive exhaust mechanism 3 includes a fixed block 31, which is fixedly connected to the left side of the front end of the flotation machine 1. A motor 32 is fixedly connected to the front end of the fixed block 31, and a turntable 33 is fixedly connected to the output shaft of the motor 32; a convex rod 34 is fixedly connected to the upper front end of the turntable 33, and a convex rod 34 is provided on the turntable 33. The outer wall of the convex rod 34 is intermittently matched with the groove wheel 35. The groove wheel 35 is provided with a plurality of grooves for inserting the convex rod 34 in the circumferential direction. A rotating shaft 36 is fixedly connected to the back of the groove wheel 35. One end of the rotating shaft 36 penetrates into the exhaust pipe 2 and is fixedly connected to a rotating block 37. The rotating shaft 36 is convenient for driving the rotating block 37 to rotate intermittently.

[0026] A chemiluminescence detector 38 is fixedly connected to the left side of the front end of the flotation machine 1. The chemiluminescence detector 38 is arranged on the left side of the exhaust pipe 2. The chemiluminescence detector 38 is electrically connected to an external display screen. The chemiluminescence detector 38 is convenient for real-time monitoring of changes in gas quality in the flotation machine 1.

[0027] The rotating shaft 36 passes through the front end of the exhaust pipe 2 and is rotatably connected to the inside thereof, and a sealing gasket is provided at the connection between the rotating shaft 36 and the exhaust pipe 2. The back of the groove wheel 35 is rotatably connected to the front end of the exhaust pipe 2, and the outer wall of the rotating block 37 is slidably connected to the inner wall of the exhaust pipe 2, so that the groove wheel 35 can easily drive the rotating shaft 36 to rotate.

[0028] When the flotation machine 1 needs to be adaptively exhausted, the gas quality change in the flotation machine 1 is monitored in real time by the chemiluminescence detector 38, and the electrical signal is transmitted to the external display screen. When the chemiluminescence detector 38 detects that the gas in the flotation machine 1 is abnormal, the motor 32 is started, the motor 32 drives the turntable 33 to rotate, the turntable 33 drives the convex rod 34 to make a circular motion, so that the convex rod 34 contacts the groove in the groove wheel 35, and drives the groove wheel 35 to rotate, the groove wheel 35 drives the rotating shaft 36 to rotate, and the rotating shaft 36 drives the rotating block 37 to rotate in the exhaust pipe 2, so that there is a gap in the exhaust pipe 2 to discharge the gas in the flotation machine 1, and adaptive exhaust is achieved according to the gas quality through the cooperation of the chemiluminescence detector 38 and the rotating block 37. At the same time, the bubble generation is dynamically adjusted according to the demand of the ore and the change of the flotation process through the adaptive exhaust, so as to improve the recovery rate of the ore, reduce the loss of tailings, and prevent the gas from affecting the normal operation of the flotation machine 1. The opening degree of the exhaust pipe 2 is adjusted through the cooperation of the groove wheel 35 and the convex rod 34, so as to achieve fine control of the gas in the flotation machine 1.

[0029] See also Figure 4 In order to increase the service life of the resin plate 48, a pretreatment mechanism 4 is also provided on the flotation machine. The pretreatment mechanism 4 includes a treatment box 41. The treatment box 41 is fixedly connected to the bottom of the exhaust pipe 2.

The air outlet of the air outlet pipe 49 is fixedly connected to a solenoid valve 410, and the solenoid valve 410 is convenient for controlling the inflow and outflow of gas; the two resin plates 48 work alternately to increase their service life.

[0030] In order to drive the two resin plates 48 to slide to detach from or enter the processing box 41, a connecting plate 42 is fixedly connected to the lower right end of the processing box 41, a frequency converter 43 is fixedly connected to the right end of the connecting plate 42, a motor 2 44 is fixedly connected to the center of the bottom of the connecting plate 42, a gear 45 is fixedly connected to the top output shaft of the motor 2 44, and the rotation axis of the gear 45 is arranged in the vertical direction, and the frequency converter 43 is convenient for controlling the rotation speed of the motor 2 44; racks 46 are meshed on both sides of the gear 45, and L-shaped rods 47 are provided on the two racks 46, and the two L-shaped rods 47 are respectively fixedly connected to the two resin plates 48, and the motor 2 44 is electrically connected to the frequency converter 43.

[0031] After the gas in the flotation machine 1 is discharged, the gas is transported to the processing box 41 through the exhaust pipe 2, and then the inverter 43 and the motor 2 44 are started. The speed of the motor 2 44 is controlled by the inverter 43, and the motor 2 44 drives the gear 45 to rotate. The gear 45 drives the two sets of racks 46 to move left and right, so that the two sets of racks 46 drive the two sets of resin plates 48 to move left and right through the L-shaped rod 47. The left and right movement of the resin plate 48 prevents the resin plate 48 from being polluted due to long-term contact with the gas, thereby improving the service life of the resin plate 48 and allowing the gas to be effectively adsorbed at any time. When the gas is adsorbed by the resin plate 48, the solenoid valve 410 is started to transport the gas in the processing box 41 to the outside through the outlet pipe 49 to prevent the gas from being directly discharged and causing damage to the external environment.

At the same time, the bubble generation is dynamically adjusted according to the demand of the ore and the change of the flotation process through the adaptive exhaust, so as to improve the recovery rate of the ore, reduce the loss of tailings, and prevent the gas from affecting the normal operation of the flotation machine 1. The opening degree of the exhaust pipe 2 is adjusted through the intermittent cooperation of a groove wheel 35 and a convex rod 34, so as to realize the fine control of the gas in the flotation machine 1. A pretreatment mechanism 4 is provided.
