Description

Technical Field

[0001] The utility model belongs to the technical field of mineral processing, and in particular relates to a system for ensuring the cleanliness of the light source of a flotation tailing coal collection device and dispersing the oil film on the surface of the ore pulp. Background Art

[0002] In the flotation process of tailings, whether it is a flotation machine or a flotation column, the discharge process of tailings is turbulent, accompanied by the splashing of slurry. There are many problems in directly photographing the coal slurry. First, if the camera lens is too close to the tailings liquid surface, the splashing slurry will inevitably contaminate the lens, which will seriously interfere with the quality of the image acquisition and even cause the system to fail; secondly, due to the limited space of the tailings tank, it is not conducive to the arrangement and installation of equipment such as light sources and cameras; in addition, since the tailings are generally flipped up from the bottom and then overflowed from the tailings gate, the upper liquid level fluctuates violently. During the flotation process, some organic reagents with good wettability are usually added to the coal slurry, such as collectors and foaming agents, which can adsorb on the surface of coal particles and form bubbles, prompting the coal particles to combine with bubbles and float into the flotation foam. These organic reagents may also form an oil film on the surface of the coal slurry, which helps to reduce the surface tension of the slurry, increase the stability of the bubbles, and thus improve the flotation effect. However, this oil film will enter the tailings tank with the slurry. Because it covers the surface of the slurry, it has an adverse effect on the acquisition of tailings images. The tailings oil film not only harms the water body and the ecosystem, but may also affect the camera's shooting of tailings. When the tailings oil film forms on the surface of the water body, it will cause reflections and spots on the water surface. The reflection of these lights will cause spots, blur or distortion in the photos taken by the camera, affecting the quality and clarity of the photos. This will cause trouble for situations where tailings detection, monitoring or recording is required. Utility Model Content

[0003] The utility model aims to solve the above problems and provide a system for ensuring the cleanliness of the light source of a flotation tailing coal collection device and dispersing the oil film on the surface of the ore pulp.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A system for ensuring the cleanliness of the light source of a flotation tailing coal collection device and dispersing the oil film on the surface of the ore pulp, comprising two light sources, a blower mechanism and an image collection device;

[0006] The image acquisition device is a camera, which is arranged just above the middle of the slurry surface, with the lens of the camera facing downward toward the slurry surface;

[0007] The two light sources are arranged above the slurry surface and symmetrically located on both sides of the camera. The light emitted by the light sources is obliquely incident on the middle of the slurry surface, and the angle between the light and the slurry surface is β;

[0008] The blowing mechanism includes a blower and a blower bracket. The blower is a double-nozzle structure and is fixed on the ground beside the flotation tailing coal pool through the blower bracket. A nozzle device is provided on the blower outlet. The nozzle device includes a first nozzle and a second nozzle. The first nozzle is obliquely upward toward the light source, and the second nozzle is horizontally arranged toward the slurry surface. The angle between the first nozzle and the second nozzle is α.

[0009] Furthermore, the angles α and β are both in the range of 30-60°.

[0010] Furthermore, the light source adopts any soft light source.

[0011] Furthermore, the first nozzle and the second nozzle outlet are both flat-mouth structures.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can reduce the situation where light is directly reflected to the camera by setting a soft light source and adjusting its incident angle. By adjusting the incident angle of the light source, a smaller angle is formed between the light and the liquid surface, which can reduce the intensity of light reflected on the liquid surface, reduce light spots and reflections, and because of the selection of a soft light source, the irradiated light is more uniform and soft;

[0014] 2. The utility model can clean the light source and the smoke and exhaust gas polluted by the light by setting a double nozzle device, so that the light source can maintain a certain illumination intensity, improve the brightness and clarity of the image, and can also blow away the oil film generated on the surface of the slurry liquid, which can not only ensure the accuracy and high precision of image data collection, but also improve the flotation effect and recovery rate;

[0015] 3. The utility model combines the soft light source and the blowing device together to make the light shine more evenly on the water surface, reduce the light spots and reflections caused by the tailings oil film, and thus improve the effect and quality of camera shooting.

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-2 As shown, a system for ensuring the cleanliness of the light source of the flotation tailing coal collection device and dispersing the oil film on the surface of the slurry includes two soft light sources 2, a blower mechanism and an image collection device;

[0021] The image acquisition device is a camera 4, which is arranged just above the middle of the slurry surface 1, and the lens 3 of the camera 4 is downwardly facing the slurry surface 1;

[0022] The two light sources 2 are soft boxes, which are arranged above the slurry surface 1 and symmetrically located on both sides of the camera 4. The light emitted by the light source 2 is obliquely incident on the middle of the slurry surface 1, and the angle β between the light and the slurry surface 1 is 45°;

[0023] The blowing mechanism includes a blower 5 and a blower bracket 8. The blower 5 is a double-nozzle centrifugal structure and is fixedly arranged on the ground beside the flotation tailing coal pool through the blower bracket 8. A nozzle device is provided on the air outlet of the blower 5. The nozzle device includes a flat-mouthed first nozzle 6 and a second nozzle 7. The first nozzle 6 is obliquely upward toward the light source 2, and the second nozzle 7 is horizontally arranged toward the slurry surface 1. The angle α between the first nozzle 6 and the second nozzle 7 is 45°.

[0024] The angles α and β may also be any value between 30-60°.

[0025] The light source 2 may also be any other soft light source.

[0026] The working process of this utility model:

[0027] When the utility model is used, the camera 4 and the light source 2 are turned on, the blower 5 is started, and the irradiation direction of the light source 2 is adjusted so that the angle between the emitted flexible illumination light and the slurry surface 1 is 45°. The flexible light emitted by the light source 2 is irradiated to the slurry surface 1, and then reflected to the lens 3 of the camera 4. The 45° incident angle and the 0° shooting angle ensure that the camera is shooting directly above the coal slurry suspension, thereby reducing the distortion rate of the captured image. Since the flexible light is obliquely incident on the slurry surface 1 instead of directly irradiating the liquid surface, the direct reflection of the light to the lens 3 of the camera 4 can be reduced. By adjusting the incident angle of the light source 2, a smaller angle is formed between the light and the liquid surface, which can also reduce the intensity of the light reflected on the liquid surface, reduce the light spot and reflection, and because the soft light source 2 is selected, the irradiation light is more uniform and soft;

[0028] Since the blower 5 is a centrifugal blower, it runs smoothly, has high reliability and stability, can run continuously for a long time without failure, and has high mechanical efficiency, can provide a large amount of airflow, achieve large air volume and high static pressure at low energy consumption, overcome pipeline resistance, and ensure that the airflow is smoothly delivered to the designated location. In addition, the centrifugal blower can achieve precise adjustment of air volume and pressure by adjusting the opening of the air inlet or outlet, which is suitable for the needs under different working conditions;

[0029] The blower 5 is externally provided with a double nozzle device, and a 45° angle is formed between the first nozzle 6 and the second nozzle 7, wherein the first nozzle 6 faces the light source 2 and the light, and cleans the smoke and exhaust gas polluted by the light source 2 and the light, so that the light source 2 maintains a certain degree of illumination intensity, and improves the brightness and clarity of the image. The second nozzle 7 horizontally faces the slurry area to blow away the oil film generated on the surface of the slurry liquid surface 1, which can not only ensure the accuracy and high precision of image data acquisition, but also improve the flotation effect and recovery rate.

[0030] By combining the light source and the blowing device together, the light can be irradiated onto the water surface more evenly, reducing the light spots and reflections caused by the tailings oil film, thereby improving the effect and quality of camera shooting.
