Description

Technical Field

[0001] This invention relates to the field of flotation equipment technology, and in particular to a shallow-tank type coarse flotation machine without mechanical stirring. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. This type of grinding mill uses a certain number of steel balls as grinding media inside its cylinder. It is widely used in industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics production for dry or wet grinding of various ores and other grindable materials. Ball mills are suitable for grinding various ores and other materials and are widely used in mineral processing, building materials, and chemical industries. They can be divided into dry and wet grinding methods. Based on the discharge method, they can be divided into grate type and overflow type.

[0003] The materials being processed (such as gold-bearing iron minerals) are usually encased in materials such as stone. To facilitate subsequent production, these materials need to be crushed. After the minerals are crushed using a ball mill, they are discharged uniformly and then screened. Finally, the crushed mineral particles are removed.

[0004] After the material is crushed, it needs to be collected and screened multiple times. This process involves repeated collection, handling, and re-screening, resulting in high labor intensity and reduced efficiency. To address these issues, we propose a shallow-tank, mechanically agitated coarse flotation machine. Summary of the Invention

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figure 1-8 A shallow-tank, non-mechanically stirred coarse flotation machine includes a tank body 1, a discharge hole on the right side of the tank body 1, a discharge pipe 10 fixed to the discharge hole, and further includes:

[0034] Several connecting pipes 2 are provided, and several through holes are provided on the lower side of the tank body 1. The connecting pipes 2 are fixedly connected to the inside of the through holes. The connecting pipes 2 are connected to the air pump through air pipes. The connecting pipes 2 are arranged in two rows at equal intervals. A filter screen 14 is fixed inside the tank body 1. The filter screen 14 is located on the upper side of the connecting pipes 2 and the lower side of the scraper 8. High-pressure gas is pushed into the water inside the tank body 1 through the connecting pipes 2 to stir up the materials in the water and separate them. The easily floating gold-bearing iron ore floats on the water surface for pretreatment, reducing the number of subsequent screening and handling, reducing labor intensity, and improving screening efficiency. The two rows of equidistantly arranged connecting pipes 2 make the stirring more uniform, while the filter screen 14 prevents materials from entering the connecting pipes 2 and causing blockage, reducing the failure rate.

[0035] Two L-shaped connecting plates 3 are detachably connected to the front and rear sides of the tank body 1 via studs and nuts. A C-shaped support plate 4 is slidably connected to the outer side of the L-shaped connecting plate 3 away from the tank body 1. A B-shaped support plate 5 is provided on the lower side of the C-shaped support plate 4. Dovetail grooves are provided on both the upper and lower sides of the L-shaped connecting plate 3 away from the tank body 1. Guide strips 15 are fixed at opposite ends on the inner side of the C-shaped support plate 4. The guide strips 15 are slidably connected to the inner side of the dovetail grooves. The L-shaped connecting plate 3 moves the tank body 1 left and right on the C-shaped support plate 4, allowing the tank body 1 to adjust its horizontal position according to the position of the ball mill discharge port. The guide strips 15 make the movement of the L-shaped connecting plate 3 within the C-shaped support plate 4 more stable.

[0036] Several lockable casters 13 are provided. The lockable casters 13 are detachably connected to the B support plate 5 by bolts and threads. The lockable casters 13 can adjust the position of the trough 1, allowing the trough 1 to move more conveniently.

[0037] Two pressure plates 11 are provided, and a limiting strip 12 is provided on the lower side of the pressure plate 11. The pressure plate 11, the limiting strip 12 and the tank body 1 are fixedly connected. The L-shaped connecting plate 3 is located between the pressure plate 11 and the limiting strip 12. The pressure plate 11 and the limiting strip 12 stabilize the connection between the L-shaped connecting plate 3 and the tank body 1, thereby improving the stability of the tank body 1.

[0038] The scraper 8 has a through hole on the right side of the tank body 1. The scraper 8 is located inside the tank body 1. The scraper 8 is used to scrape the gold-bearing iron ore floating on the water body out of the tank body 1 through the through hole. Then, the scraped gold-bearing iron ore is collected through a pipe connected to the through hole.

[0039] A fixing unit 6 is provided between the L-shaped connecting plate 3 and the C-shaped support plate 4. The fixing unit 6 includes a positioning bolt 61. An L-shaped support block 62 is fixed on the upper side of the L-shaped connecting plate 3 away from the tank 1. The C-shaped support plate 4 is slidably connected to the inner side of the L-shaped support block 62.

When the position of the tank 1 is fixed, the positioning bolt 61 is tightened and pressed onto the C-shaped support plate 4. The L-shaped connecting plate 3 is fixed by the L-shaped support block 62, which restricts the horizontal movement of the tank 1.

[0040] A lifting unit 7 is provided between the C-shaped support plate 4 and the B-shaped support plate 5. The lifting unit 7 includes two motors 71. Several telescopic rods 72 are fixed to the lower side of the C-shaped support plate 4. Driven cylinders 73 are fixed to both ends of the side of the C-shaped support plate 4 away from the tank body 1. Guide cylinders 74 are slidably connected to the lower outer side of the telescopic rods 72. A screw 75 is threadedly connected to the inner side of the driven cylinder 73. The lower end of the screw 75 is fixedly connected to the shaft end of the motor 71. An A-shaped support block 76 is fixed to the lower end of the motor 71, and the A-shaped support block 76 is fixedly connected to the B-shaped support plate 5. The screw 75 is driven vertically and horizontally. Both ends are rotatably connected to support rings 77. A support plates 78 are provided on both the left and right sides of the screw 75. The support rings 77 and A support plates 78 are fixedly connected. The A support plates 78 and A support blocks 76 are fixedly connected. The motor 71 is connected to the power supply and controller through wires. The motor 71 drives the screw 75 to rotate inside the support rings 77. As the screw 75 rotates, the driven cylinder 73 moves up and down, and moves up and down with the C-shaped support plate 4, realizing the up and down movement of the tank 1. The telescopic rod 72 and the guide cylinder 74 play a guiding role for the tank 1.

[0041] A support unit 79 is provided between the tank body 1 and the B support plate 5. The support unit 79 includes four guide rods 791 and two C support plates 792. A movable ring 795 is slidably connected to the outer side of the guide rods 791. The movable ring 795 is fixedly connected to the C support plates 792. A support bar 793 is fixed to the side of the C support plate 792 facing the tank body 1. A positioning nut 794 is provided on the lower side of the movable ring 795. The positioning nut 794 is detachably connected to the guide rods 791 by threads. After the tank body 1 is moved to a suitable height, the support bar 793 is moved to the lower side of the tank body 1, and the positioning nut 794 is screwed under the movable ring 795 to prevent the support bar 793 from falling down. This provides support for the tank body 1 and improves the safety of the tank body 1.

[0042] A transmission unit 9 is provided between the pressure plate 11 and the scraper 8. The transmission unit 9 includes two A electric push rods 91 and two A electric telescopic rods 92. A connecting block 93 is fixed on the upper side of the scraper 8. A guide plate 94 is slidably connected to the outer side of the connecting block 93. The shaft end of the A electric telescopic rod 92 is fixedly connected to the connecting block 93. The A electric telescopic rod 92 is fixedly connected to the upper side of the guide plate 94. The guide plate 94 is fixedly connected to the moving end of the A electric push rod 91. The A electric push rod 91 is fixedly connected to the pressure plate 11. The A electric push rod 91 and the A electric telescopic rod 92 are connected to the power supply and the controller through wires. The A electric telescopic rod 92 moves the scraper 8 up and down through the connecting block 93. Then, the A electric push rod 91 drives the scraper 8 to move horizontally in the tank 1 through the guide plate 94, so that the scraper 8 automatically scrapes and collects the gold-bearing iron ore floating on the water in the tank 1, thereby improving the automation level of the equipment.

[0043] Operating principle:

[0044] The height of the tank 1 is adjusted by the lifting unit 7, water is injected into the tank 1, and the connecting pipe 2 is connected to the air pump through the air pipe. Air is pumped from the connecting pipe 2 into the water in the tank 1, causing the water in the tank 1 to flow. After the material of the ball mill enters the tank 1, it will be separated with the flow of water. The material that is easy to float, such as gold-bearing iron ore, floats on the water surface, while other heavier materials sink on the filter screen 14. The transmission unit 9 uses the scraper 8 to scrape the material that is easy to float (such as gold-bearing iron ore) from the water surface, which realizes pretreatment, reduces labor intensity, and improves screening efficiency.
