Description

Technical Field

[0001] This utility model belongs to the field of mineral processing technology, specifically relating to a uniformly distributed flotation machine feed box. Background Technology

[0002] In the production processes of mineral flotation separation, concentration, and dewatering, the low operating efficiency of equipment is often caused by uneven distribution and feeding of slurry. Conventional pipeline distribution has the problem of unstable output, concentrated output, and difficulty in uniform distribution. This is especially evident in the feeding of equipment such as flotation machine feed boxes and jigs, resulting in low equipment efficiency and affecting the overall output of the mineral processing process. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the existing technology of double-row flotation machines where the slurry feed cannot be evenly distributed, resulting in low operating efficiency, large fluctuations in the thickness of the flotation froth layer, froth tank overflow and ore spillage, and easy blockage of equipment channels. The invention provides a flotation machine feed ear box with a simple structure, easy manufacturing, and low cost for uniform material distribution.

[0004] To solve the above problems, the present invention adopts the following technical solution: A uniformly distributed flotation machine feed box includes a slurry conveying pipe, a mixing buffer tank, a mixing discharge pipe, and a feed box. The top of the mixing buffer tank is connected to multiple slurry conveying pipes, and the center of the front end is connected to a mixing discharge pipe. The outlet of the mixing discharge pipe is connected to the feed ear box. The bottom two sides of the feed ear box are equipped with flotation machine feed pipes. Two distribution baffles and distribution gates are installed inside the feed pipes at the bottom of the feed ear box. By adjusting the height of different distribution gates, the amount of slurry in different feed pipes at the bottom of the feed ear box can be controlled.

[0005] Furthermore, the mixing buffer box and the feed ear box are lined with rubber throughout.

[0006] Furthermore, the connection point of the mixing discharge pipe is located on the center line of the left and right sides of the feed ear box, forming a 'T'-shaped vertical connection.

[0007] Furthermore, the material distribution baffle is concave, and the two material distribution baffles are symmetrical about the center line of the feed ear box, with the same height, and the height of the baffle is slightly higher than the upper edge of the mixing discharge pipe.

[0008] Furthermore, a distributing gate is installed on the inner side of both distributing baffles. A lead screw is welded to the distributing gate, and a connecting nut is threaded to the lead screw. The connecting nut is connected to a handwheel and is located on the outer side of the top of the feed ear box. The height of the distributing gate is adjusted by rotating the handwheel.

[0009] The beneficial effects of this utility model are as follows: 1. This invention solves the problem in existing technologies where the slurry feed of double-row flotation machines cannot be evenly distributed, resulting in low operating efficiency and large fluctuations in the thickness of the flotation froth layer.

[0010] 2. It solved the problems of uneven feeding of slurry into downstream equipment, flotation machine foam tank overflow and ore spillage, and easy blockage of equipment channels.

[0011] 3. It achieves adjustable and uniform distribution of slurry; it is easy to operate, the process is safe and simple, and the surrounding environment is kept clean during the distribution process. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figure 1 and 2 As shown, a uniformly distributed flotation machine feed box includes a slurry conveying pipe 1 and a mixing buffer tank 2. One end of the mixing buffer tank 2 is connected to multiple slurry conveying pipes 1, and the other end is connected to a mixing discharge pipe 3. The outlet of the mixing discharge pipe 3 is connected to the feed box 4. Flotation machine feed pipes 5 are installed on both sides of the bottom of the feed box 4. Two distribution baffles 6 and distribution gates 7 are installed inside the bottom feed pipes of the feed box 4. By adjusting the height of different distribution gates 7, the amount of slurry in different feed pipes at the bottom of the feed box 4 can be precisely controlled.

[0014] The outlet of the slurry conveying pipe 1 and the mixing buffer tank 2 have a certain angle, with about 90° being the best. The advantage of this is that it can prevent the slurry from impacting the side of the mixing buffer tank 2 and reduce the wear of the mixing buffer tank 2.

[0015] The inner side of the mixing buffer tank 2 is lined with rubber. The mixing discharge pipe 3 is installed in the middle of the mixing buffer tank 2. The connection parts should be deeply crossed, forming a '+' connection. The advantage is that the rubber lining can delay wear and prevent the slurry from accumulating on the inner wall of the tank. The bottom of the mixing discharge pipe 3 and the bottom of the mixing buffer tank 2 are left with a height difference, which can make the bottom of the mixing buffer tank 2 accumulate ore sand, avoid wear on the bottom of the tank, and ensure the service life of the tank.

[0016] The other end of the mixing discharge pipe 3 is connected to the feed ear box 4. The connection point should be located on the center line of the left and right sides of the feed ear box 4, forming a vertical 'T' shape. The vertical position should not be too high. The advantage is that when the slurry reaches the feed ear box 4 through the mixing discharge pipe 3, the distance from the flotation machine feed pipes 5 on the left and right sides of the bottom of the feed ear box 4 is equal. At the same time, since the mixing discharge pipe 3 and the feed ear box 4 are connected vertically in a 'T' shape, the slurry flows downward along the center, and the slurry flows evenly to the left and right.

[0017] Like the mixing buffer tank 2, the feed ear box 4 is lined with rubber on the inside. Two distribution baffles 6 are installed at the bottom of the feed ear box 4. The distribution baffles 6 are concave in shape and are symmetrical about the center line of the feed ear box 4. They are at the same height and the height of the baffles is slightly higher than the upper edge of the mixing discharge pipe 3. The advantage is that when the slurry enters the feed ear box 4 through the mixing discharge pipe 3, the baffles can buffer the slurry and slow down the slurry flow rate. At the same time, they regulate the flow of the slurry. After the slurry enters the feed ear box 4, the slurry level between the two baffles rises and slowly and evenly overflows from the concave plane between the two distribution baffles 6.

[0018] Both material distribution baffles 6 have material distribution gates 7 on their inner sides. Screws 9 are welded to the gates, and connecting nuts 8 are threadedly connected to the screws 9. The connecting nuts 8 are connected to the handwheel 10 and are located on the top outer side of the feed ear box 4. Its advantage is that as the handwheel 10 is turned, the gate moves up and down under the drive of the connecting nuts 8. By adjusting the height of the two material distribution gates 7, the height of the material distribution baffles 6 can be controlled, thereby adjusting the discharge flow on the left and right sides and achieving uniform material distribution and stable feeding of different flow rates.

[0019] The working principle of this utility model is as follows: The slurry enters the mixing buffer tank 2 through multiple slurry conveying pipes 1. After being mixed and constrained by the mixing buffer tank 2, it enters the mixing discharge pipe 3. Through the mixing discharge pipe 3, it enters the feed ear box 4 vertically. Then, under the constraint of the distribution baffle 6, the slurry flow rate slows down and the liquid level rises. It flows evenly to the flotation machine feed pipes 5 on both sides through the recessed opening of the distribution baffle 6. Under this condition, uniform distribution can generally be achieved, but the accuracy is low. If the required accuracy is not achieved, the two handwheels 10 on the left and right can be turned. Driven by the connecting nut 8 and the screw 9, the two distribution gates 7 on the left and right can be moved up and down to adjust the height of the baffles, so that the slurry is discharged from the recessed opening of the distribution baffle 6 evenly or at different flow rates.

[0020] This invention features a simple structure and convenient operation, achieving uniform distribution of slurry and solving the problem of uneven slurry distribution in existing double-row flotation machines, thereby improving the production efficiency of downstream equipment.
