DETAILED DESCRIPTION

[0017] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0018] Please see the attached Figure 1 As shown, a visual identification device for ash content in tailings slurry of coal slime flotation comprises a buffer box 1 and an aggregate box 6 arranged on the side of the buffer box 1. The height of the buffer box 1 is higher than the height of the aggregate box 6. A three-way pipe 4 is connected between the bottom of the buffer box 1 and the aggregate box 6. One end of the three-way pipe 4 connected to the aggregate box 6 is connected to a detection disk 7 placed in the aggregate box 6. The height difference between the buffer box 1 and the aggregate box 6 ensures that the tailings slurry in the buffer box 1 can enter the detection disk 7 through the three-way pipe 4, and the bottoms of the buffer box 1 and the aggregate box 6 are both inclined to facilitate the discharge of the slurry inside the box.

[0019] Please see the attached Figure 2 As shown, the inspection disk 7 is composed of an outer cone ring 701 and an inner cone ring 702. The outer cone ring 701 has a small opening at the top and a large opening at the bottom, while the inner cone ring 702 has a small opening at the bottom and a large opening at the top. The small opening of the outer cone ring 701 and the large opening of the inner cone ring 702 are fixedly connected. A visual recognition camera 13 is located above the aggregate box 6, directly opposite the inspection disk 7. Specifically, the slurry first gradually fills the inner cone ring 702 through the three-way pipe 4, then overflows into the outer cone ring 701 and flows downward along the surface of the outer cone ring 701 into the aggregate box 6, ensuring laminar flow of the tailings slurry, which is convenient for the visual recognition camera 13 to take pictures and identify.

[0020] In the above embodiment, preferably, the angle α between the busbar of the outer cone ring 701 and the central axis and the angle β between the busbar of the inner cone ring 702 and the central axis are the same, and the angle α is 70°~85°, wherein the angle α and the angle β are preferably 80°. The larger the angle, the larger the area exposed to the visual recognition camera 13 during laminar flow of the slurry, which is more conducive to the visual recognition camera 13 to capture the particles in the slurry, improve the clarity of visual identification of particles in the tailings slurry and the accuracy of tailings slurry ash detection, while ensuring that the slurry is smoothly discharged along the outer cone ring 701.

[0021] The three-way pipe 4 includes a first branch pipe 401, a second branch pipe 404 and a third branch pipe 403 that are interconnected. One end of the first branch pipe 401 is connected to the bottom end of the buffer box 1, and one end of the second branch pipe 404 passes through the bottom of the aggregate box 6 and is connected to the small opening of the inner cone ring 702. The first branch pipe 401 is provided with a regulating valve 402 for adjusting the flow rate, and the regulating valve 402 can also be used to control the flow rate of the slurry in the second branch pipe 404. The third branch pipe 403 is provided with a drain valve 405, which can be used to empty the slurry in the buffer box 1 during cleaning or to discharge the slurry to the next process for use.

[0022] A feed pipe 2 is provided above the buffer box 1, an overflow pipe 3 is provided on the side of the buffer box 1, and a tailings pipe 5 is provided at the bottom end of the collecting box 6. When the flow rate of tailings slurry fed into the feed pipe 2 is too large, it can flow out of the device through the overflow pipe 3 to ensure stable and reliable operation of the device.

[0023] Please see the attached Figure 1 As shown, the visual recognition camera 13 is installed above the aggregate box 6 through an adjustable component, and the adjustable component includes a camera fixing plate 12, multiple screws 8 fixed to the aggregate box 6 and nuts 9, each screw 8 is provided with at least two nuts 9, and mounting holes are opened at both ends of the camera fixing plate 12 (not shown in the accompanying drawings), and both ends of the camera fixing plate 12 are sleeved on the screw 8 through the mounting holes and placed between the two nuts 9. The visual recognition camera 13 is installed on the lower surface of the camera fixing plate 12. The distance between the visual recognition camera 13 and the detection disk 7 can be adjusted by moving the camera fixing plate 12 up and down to find the best shooting position, and the camera fixing plate 12 is clamped and stabilized by tightening the two nuts 9.

[0024] Among them, a light source fixing plate 10 is also fixed on the screw 8 through a nut 9, and the light source fixing plate 10 is placed below the camera fixing plate 12. The light source fixing plate 10 and the camera fixing plate 12 are fixed on the screw 8 in the same principle, and a ring light source 11 is provided on the light source fixing plate 10 and is placed directly below the visual recognition camera 13. The distance between the ring light source 11 and the visual recognition camera 13 can also be adjusted by adjusting the nut 9 until the image of the detection disk 7 is clearly imaged.

[0025] Specific working process:

[0026] The tailings slurry enters the buffer tank 1 through the feed pipe 2, the regulating valve 402 is opened, and the drain valve 405 is closed. By adjusting the regulating valve 402 of the three-way pipe 4, the tailings slurry is allowed to flow through the second branch pipe 404 to the detection tray 7; or the regulating valve 402 is opened and the drain valve 405 is partially opened, so that part of the tailings slurry flows through the third branch pipe 403 to the next process, and the other part of the tailings slurry is diverted into the detection tray 7 for ash content detection;

[0027] Then, by adjusting the nut 9 on the screw 8, the height of the light source fixing plate 10 and the camera fixing plate 12 can be adjusted, and then the height of the annular light source 11 and the visual recognition camera 13 can be adjusted until the image of the detection disk 7 is clearly imaged. The visual recognition camera 13 captures and identifies the tailings slurry of the detection disk 7. At the same time, the tailings slurry of the detection disk 7 overflows from the outer cone ring 701 into the aggregate box 6 and flows out of the device through the tailings pipe 5.

[0028] During the entire process, the slurry continues to flow in a laminar flow and the visual recognition camera 13 continuously takes pictures and identifies without human intervention. This effectively solves the problems of poor real-time performance, high labor intensity, complicated procedures, and large errors in traditional manual sampling and testing, and effectively ensures the stability of product quality.

[0030] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
