[0019] Combined with Figure 1-2 , the specific implementation mode of the present invention is described as follows:

[0020] Embodiment 1:

[0021] like Figure 1 , Figure 2 As shown, a wet ore color sorter comprises a color sorting frame 2 and a color sorting mechanism and a material receiving hopper 5 installed in the color sorting frame 2 . The material receiving hopper 5 is installed at the rear end of the color sorting frame 2 .

[0022] A feeding frame 1 is provided on the front side of the color sorting frame 2 and is equipped with a vibrating screening mechanism. The vibrating screening mechanism installed on the front side of the color sorting frame 2 is used to vibrate and screen the wet ore, so that the wet ore can be shaken evenly and fine impurities, water vapor and mud contained in the wet ore can be preliminarily removed.

[0023] A material conveyor belt 3 is installed at the front end of the color sorting frame 2, and a waste receiving device 4 is arranged below the rear end of the material conveyor belt 3. The waste receiving device 4 can further remove the remaining impurities, water vapor and mud in the wet material ore thrown out from the end of the material conveyor belt 3.

[0024] The color sorting mechanism includes a spray valve device 6 and two sets of color sorting box systems 8. The two sets of color sorting box systems 8 are respectively installed at the front lower part and the rear upper part of the receiving hopper 5, and the spray valve device 6 is installed above the receiving hopper 5. The two sets of color sorting box systems 8 in the color sorting mechanism are arranged in an inclined manner, which can not only avoid the water vapor and mud contained in the wet material ore from falling onto the sorting box glass of the color sorting box system 8, thereby reducing the adverse effects of color sorting identification and reducing the cleaning frequency, but also can shoot the material reference point 100 through the small gap between the waste receiving device 4 and the receiving hopper 5, and the identification effect is good.

[0025] Embodiment 2:

[0026] like Figure 1 , Figure 2 As shown, a wet ore color sorter includes a color sorting frame 2 and a color sorting mechanism and a receiving hopper 5 installed in the color sorting frame 2.

[0027] A feed frame 1 is provided at the front side of the color sorting frame 2 and a vibrating screening mechanism is installed. The vibrating screening mechanism includes a feed hopper 11, a screen 12, a vibrator 13 and a waste hopper 14. The screen 12 is installed on the top of the feed frame 1 through the vibrator 13. The feed hopper 11 is installed above the screen 12 and installed on the feed frame 1 through a bracket. The waste hopper 14 is installed below the screen 12 and fixed in the frame 1. The vibrator 13 includes a vibration motor, and the screen 12 is vibrated by the vibration motor. The vibration of the screen 12 controlled by the vibrator 13 installed on the front side of the color sorting frame 2 can vibrate and screen the wet material ore, and can shake the wet material ore evenly. At the same time, the fine impurities, water vapor and mud contained in the wet material ore are separated from the wet material ore through the screen 12 and collected in the waste hopper 14, so as to preliminarily remove the fine impurities, water vapor and mud contained in the wet material ore.

[0028] A material conveyor belt 3 is installed on the front end of the color sorting frame 2, and an inclined acceleration plate 15 is arranged between the discharge port of the screen 12 and the front end of the material conveyor belt 3. The wet ore on the screen 12 of the feed frame 1 transitions through the inclined acceleration plate 15 and falls onto the material conveyor belt 3 for transmission.

[0029] A waste receiving device 4 is provided below the rear end of the material conveyor belt 3. The waste receiving device 4 is composed of a receiving box and an air suction device. The receiving box is installed below the rear end of the material conveyor belt 3. An air outlet 41 is provided at the bottom of the receiving box and is connected to the air suction device through a pipeline. After the wet ore raw material is thrown out at the rear end (end) of the material conveyor belt 3, its motion trajectory parabola is located above the waste receiving device 4. The remaining impurities, water vapor and mud in the wet ore are further removed under the negative pressure of the waste receiving device 4.

[0030] The receiving hopper 5 is installed at the rear end of the color sorting frame 2. The receiving hopper 5 is divided into a defective hopper at the front and a qualified hopper at the rear by a partition plate. After the wet ore raw material is thrown out at the rear end (end) of the material conveyor belt 3, when it moves to a certain position, the color sorting mechanism sorts it, and the sorted defective ore and qualified ore fall into the defective hopper and qualified hopper respectively, and this certain position is the material reference point 100 during color sorting in the color sorting mechanism. The material reference point 100 is located above the defective hopper.

[0031] The color sorting mechanism includes a spray valve device 6 and two sets of color sorting box systems 8. The two sets of color sorting box systems 8 are symmetrically installed at the front lower and rear upper parts of the defective material hopper of the receiving hopper 5 with the material reference point 100 as the center, and the spray valve device 6 is installed above the receiving hopper 5.

[0032] Among them, the color sorting box system 8 includes a color sorting box, a camera 82, a reflector 83, a background light 84 and a lighting lamp 85. A glass mounting hole is set on the end face of the color sorting box facing the material reference point 100 and a transparent glass 81 is installed. The background light 84 and the lighting lamp 85 are both set opposite to the transparent glass 81 and installed in the color sorting box. The camera 82 and the reflector 83 are both installed in the color sorting box, and the camera 82 shoots the position of the material reference point 100 through the reflector 83 and the transparent glass 81.

[0033] The material reference point 100 and the background light 84 in the color sorting box system 8 at the upper rear and the camera 82 in the color sorting box system 8 at the lower front are respectively located on the incident light and the reflected light of the reflector 83 in the color sorting box system 8 at the lower front. The material reference point 100 and the background light 84 in the color sorting box system 8 at the lower front and the camera 82 in the color sorting box system 8 at the upper rear are respectively located on the incident light and the reflected light of the reflector 83 in the color sorting box system 8 at the upper rear. Although the setting of the reflector 83 has a certain influence on the recognition of the camera 82 and the wet ore raw materials, the influence is not great and is within an acceptable range; at the same time, the internal space of the color sorter can be fully utilized. Through the reasonable arrangement of the material reference point 100, the reflector 83 and the camera 82, the volume of the whole machine is significantly reduced, which is convenient for the installation of other components.

[0034] The two sets of color sorting box systems 8 in the color sorting mechanism are arranged at an angle, that is, the color sorting box system 8 located at the front lower part is installed below the waste receiving device 4, so that the fine impurities, water vapor and mud contained in the wet material ore will be absorbed by the waste receiving device 4 and will not fall onto the sorting box glass of the color sorting box system 8. It can not only avoid the pollution of the sorting box glass by the water vapor and mud contained in the wet material ore, thereby reducing the adverse effects of color sorting identification and reducing the cleaning frequency, but also can take pictures of the material reference point 100 through the small gap between the waste receiving device 4 and the receiving hopper 5, and the identification effect is good.

[0035] A gap space is provided between the defective product hopper and the waste receiving device 4, and the camera 82 is set with a long object distance. The camera 82 in the color sorting box system 8 located at the front lower part shoots the position of the material reference point 100 through its reflector 83, transparent glass 81 and the gap space.

[0036] A water spray system and a dust removal brush are provided on the outside of the perspective glass 81 in the color sorting box system 8 located at the front lower part. The dust removal brush is controlled by a motor to move back and forth to realize regular automatic cleaning of dust adhering to the perspective glass 81, fine impurities contained in wet material ore, water vapor and mud, while the water spray system can spray water on the perspective glass 81 through a nozzle to remove dirt.

[0037] The invention discloses a wet ore color sorter, which has a compact structure, can effectively remove water vapor and mud contained in the wet ore, reduce the probability of their accumulation on the glass of the sorting box, reduce the frequency of cleaning the glass of the sorting box, improve the recognition accuracy of the wet ore raw materials, has good color sorting effect, is easy to use and has high reliability.

[0038] The above is an exemplary description of the invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
