Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing equipment technology, specifically to a liquid level regulating device for mineral processing slurry scraping. Background Technology
[0002] In a flotation machine, after the slurry has been treated with reagents, it is agitated and aerated, causing some mineral particles to selectively adhere to the air bubbles. These particles float on the surface of the slurry and are scraped off to form a froth product, while the rest remain in the slurry, thus achieving the purpose of mineral separation. During the flotation process, it is necessary to control the liquid level in the flotation cell to ensure that the foam floating on the surface of the slurry can be scraped off to the maximum extent. Existing flotation cells generally use level gauges for liquid level detection. However, due to the large amount of foam and the small amount of liquid attached to the foam, the level gauges are not accurate enough, and the slurry in the flotation cell continues to overflow, resulting in some waste.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution:
[0020] A liquid level regulating device for mineral processing includes a flotation cell 1, a slurry feed pipe 5 connected to the side of the flotation cell 1, a control valve 6 installed on the slurry feed pipe 5, a lifting support frame 16 installed on the outer side of the flotation cell 1 by mounting bolts 18, a lifting adjustment component installed on the side of the lifting support frame 16, a connecting frame 13 connected to the lifting adjustment component, a float block 2 slidably connected to the bottom of the connecting frame 13, a pressure sensor 7 installed on the lower surface of the connecting frame 13, a top rod 23 cooperating with the pressure sensor 7 provided on the upper surface of the float block 2, and a display screen 14 installed on the top of the lifting support frame 16, with a microcontroller unit 15 installed on the display screen 14.
[0021] The end of the slurry feed pipe 5 is connected to a connecting plate 3, and multiple connecting bolts 4 are installed on the side of the connecting plate 3.
[0022] The lifting adjustment assembly includes a lead screw 9 vertically rotatably connected to the side of the lifting support frame 16 and a guide rod 11 vertically fixedly connected to the side of the lifting support frame 16. A slider 12 that is slidably connected to the guide rod 11 is installed on the lead screw 9. A servo motor 17 located at the bottom of the lifting support frame 16 is connected to the end of the lead screw 9. A connecting frame 13 is connected to the side of the slider 12.
[0023] The slider 12 has a pointer 10 on its side, and the lifting support frame 16 has a scale 8 on its side that cooperates with the pointer 10.
[0024] A fixed sliding hole 21 is provided on each side of the lower part of the connecting frame 13. A connecting rod 20 is slidably connected in the fixed sliding hole 21. The top of the connecting rod 20 is connected to the connecting rod 20, and the float block 2 is connected to the bottom of the connecting rod 20.
[0025] A spring 19 is sleeved on the circumference of the connecting rod 20. The spring 19 is located between the float block 2 and the connecting frame 13. The spring 19 can prevent the top rod 23 from putting too much pressure on the pressure sensor 7. When the float block 2 is stationary, the spring 19 is in a relaxed state. When the float block 2 moves upward, the spring 19 begins to compress.
[0026] Based on the height of the flotation tank liquid level, the servo motor 17, in conjunction with the lead screw 9, guide rod 11, and slider 12, drives the float block 2 to rise and fall to a suitable height. When the slurry enters the flotation tank through the slurry feed pipe 5 and the liquid level in the flotation tank reaches a certain height, the float block 2 floats upward using the buoyancy of the slurry, causing the top rod 23 to press against the bottom of the pressure sensor 7. The pressure sensor 7 transmits data to the microcontroller unit 15, which controls the control valve 6 on the slurry feed pipe 5 to close. At the same time, the microcontroller unit 15 transmits data to the display screen 14, which displays the pressure value, thus informing the staff that the height of the slurry in the flotation tank has reached the preset height. As the float block 2 rises and falls with the slider 12, the pointer 10, in conjunction with the scale 8, allows for a direct visual observation of the slurry level in the flotation tank.
[0027] The control valve 6, pressure sensor 7, display screen 14, microcontroller unit 15 and servo motor 17 are all common models available on the market. The control valve 6, pressure sensor 7, display screen 14 and servo motor 17 are electrically connected to the microcontroller unit 15, and their connection relationship is a common method in the prior art.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
