Description

Technical Field

[0001] The utility model relates to the technical field of flotation machines, in particular to an anti-splash ore flotation machine. Background Art

[0002] Flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the slurry treated with reagents is stirred and aerated, so that some mineral particles are selectively fixed on the bubbles, float to the surface of the slurry and are scraped out to form foam products, while the rest are retained in the slurry to achieve the purpose of separating minerals.

[0003] When the flotation machine is in operation, the slurry and flotation reagents are stirred and aerated. The mineral particles in the slurry come into contact and collide with the bubbles. The buoyant mineral particles selectively adhere to the bubbles and are carried upward to form a mineralized foam layer composed of gas, liquid and solid phases. The flotation machine impeller then rotates counterclockwise and scrapes the foam product that floats to the surface of the slurry into the U-shaped chute. During this process, the slurry splashes and the foam bursts. The foam burst is accompanied by the release of metal particles, which float in the air and enter the human lungs through breathing, endangering human health and causing the loss of foam product.

[0004] Therefore, a rotatable anti-splashing protective cover is provided on the flotation machine, which can intercept the ore pulp and metal particles, thereby protecting the health of the workers and reducing losses. However, the setting of the protective cover affects the workers' observation of the ore pulp situation inside the flotation machine. Based on this, a flotation machine with anti-splashing ore is provided. Utility Model Content

The front end of the flotation box 101 and the top of the collection tank 102 are provided with an anti-splash ore assembly 2, which is used to intercept the ore pulp and the metal particles generated by the foam burst;

[0036] The anti-splash ore assembly 2 includes a protection unit and a scraper unit;

[0037] The protection unit is used to intercept the metal particles generated by the slurry and foam burst;

[0038] The scraping unit is used to scrape the observation window 202 in the protection unit, so that the staff can observe the slurry through the observation window 202;

[0039] The protection unit includes a protection cover 201, an observation window 202, a rotating cylinder 203, a fixed support arm 204, a flip gear 205, a driving gear 206, and a second worm gear reducer 207;

[0041] The observation window 202 is embedded in the inner side of the front end of the protective cover 201. The observation window 202 is used to facilitate the staff to observe the slurry situation;

[0042] The rotating cylinder 203 is symmetrically fixed to the bottom of the rear ends of both sides of the protective cover 201, and the fixed support arms 204 are symmetrically fixed to both sides of the outer wall of the flotation box 101, and the protective cover 201 is rotatably connected to the middle of the two fixed support arms 204 through the rotating cylinder 203;

[0047] The reciprocating screw rod 208 is located at the rear end of the inner side of the protective cover 201 and both ends of the reciprocating screw rod 208 pass through the protective cover 201 and the two rotating cylinders 203, and the reciprocating screw rod 208 is rotatably connected to the protective cover 201 and the rotating cylinders 203;

[0048] The first linkage gear 209 is fixed to one side of the reciprocating screw 208 and is distributed on the side of the flip gear 205 away from the flotation box 101. The second linkage gear 210 is fixed to the side of the rotating shaft 1044 away from the transmission wheel 1042, and the second linkage gear 210 is meshed with the first linkage gear 209. When the rotating shaft 1044 rotates, the reciprocating screw 208 rotates through the cooperation of the second linkage gear 210 and the first linkage gear 209.

[0049] The reciprocating scraper 211 is sleeved on the outside of the reciprocating screw 208 and a pin block matching the spiral groove on the outer wall of the reciprocating screw 208 is installed on the inner side of the annular part of the reciprocating scraper 211. The scraper part of the reciprocating scraper 211 is attached to the inner side of the protective cover 201. The rotating reciprocating screw 208 drives the reciprocating scraper 211 to move back and forth, so as to realize the wall scraping operation on the inner surface of the protective cover 201 and the observation window 202.

[0050] In this embodiment, it should be noted that the stirring assembly 103 is mainly used to drive the impeller to rotate to form a negative pressure in the wheel cavity, so that the slurry, air, and reagents are fully mixed. The stirring assembly 103 is a conventional structure of the flotation machine, so it is not described in detail.

[0051] During daily operation of the flotation machine, the first worm gear reducer 1041, the transmission wheel 1042, and the transmission belt 1043 cooperate to drive the rotating shaft 1044 to rotate, and the rotating shaft 1044 drives the scraper plate to move in a circular motion, thereby scraping the foam into the collection tank 102, thereby achieving the purpose of separating minerals.

[0052] During this process, the protective cover 201 covers the upper surface of the front end of the flotation box 101 and the upper surface of the collecting tank 102, which can intercept the slurry and metal particles generated by the foam burst, which not only protects the health of the workers but also reduces losses.

[0053] At the same time, the rotating shaft 1044 drives the second linkage gear 210 to rotate, the second linkage gear 210 drives the first linkage gear 209 to rotate, and the first linkage gear 209 drives the reciprocating screw 208 to rotate. The rotating reciprocating screw 208 can drive the reciprocating scraper 211 to move back and forth, thereby scraping the inner surface of the protective cover 201 and the observation window 202, so that the observation window 202 maintains a good observation effect, so that the staff can observe the slurry situation through the observation window 202;

[0054] If the protective cover 201 needs to be opened, the second worm gear reducer 207 can be started. The second worm gear reducer 207 cooperates with the adjustable rotating cylinder 203 to rotate through the driving gear 206 and the flip gear 205. The rotating cylinder 203 drives the protective cover 201 to flip open, while the reciprocating screw 208 and the reciprocating wall scraper 211 remain in their original state without interference.

[0055] Please refer to Figures 1 to 6 An L-shaped rail groove 105 is provided at the upper edge of the collecting trough 102 away from the flotation box 101 , and one end of the scraper of the reciprocating scraper 211 extends to the inside of the L-shaped rail groove 105 and is slidably connected to the L-shaped rail groove 105 .

[0056] In this embodiment, the L-shaped rail groove 105 can guide and limit the movement of the reciprocating scraper 211 to prevent the reciprocating scraper 211 from rotating. In addition, the bottom of the L-shaped rail groove 105 is connected to the inner side of the collection tank 102, thereby facilitating the cleaning operation of the metal particles remaining inside the L-shaped rail groove 105.

[0057] Please refer to Figures 1 to 6 The distribution length of the bidirectional spiral groove of the reciprocating screw 208 is greater than the length of the observation window 202, and the bottoms of both ends of the protective cover 201 are formed with notch grooves that match the rotating shaft 1044.

[0058] In this embodiment, this structure allows the operating area of the reciprocating scraper 211 to be larger than the observation window 202 area, thereby achieving sufficient scraping operation on the observation window 202 , while the notch groove can prevent interference between the protective cover 201 and the operation of the rotating shaft 1044 .

[0059] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
