Description

Technical Field

[0001] The utility model relates to the technical field of ore separation, and particularly relates to an ore separator. Background Art

[0002] Traditional ore separators mostly use vibrating feeders for vibrating ore feeding. Specifically, the raw ore is evenly vibrated and scattered by the vibrating feeder, and then the sorting of qualified ore is completed by using X-ray imaging recognition technology in cooperation with the actuator.

[0003] When the ore separator uses a vibrating feeder for feeding, the high-frequency vibration generated by the vibrating motor will inevitably affect the stability of the equipment.

[0004] In addition, traditional intelligent ore separation equipment has high requirements for the plant space. According to the actual market situation, the plants of user mines generally have limited height and space, resulting in difficult equipment installation. In some cases, plant transformation is even required, which greatly increases the input cost of users and extends the investment return period of user enterprises. Content of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the defect that the high-frequency vibration generated by using a vibrating feeder for feeding in the existing ore separator affects the stability of the equipment, so as to provide an ore separator.

[0006] To solve the above technical problem, the utility model provides an ore separator, including:

[0010] A graphic recognition mechanism arranged below the output end of the conveyor belt, and the graphic recognition mechanism is used for performing photographing detection on the ore output from the conveyor belt and falling and feeding the detection result back to the controller;

[0011] A sorting actuator arranged below the ray detection mechanism and the graphic recognition mechanism, and the sorting actuator is used for sorting the ore output from the conveyor belt and falling according to the control of the controller.

[0012] Optionally, there are two conveyor belts symmetrically arranged below the discharge port.

[0013] Optionally, a material distributing member is provided at the bottom of the discharge port of the bin, and the material distributing member has a protruding end extending towards the bin and inclined surfaces or arc surfaces symmetrically arranged relative to the protruding end.

[0014] Optionally, the ray detection mechanism includes a ray source provided outside the falling trajectory of the ore and a detector provided inside the falling trajectory of the ore.

[0032] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] Such as Figure 1 , Figure 2As shown in the figure, a specific implementation of the ore separator provided in this embodiment includes: a feed bin 1, a conveyor belt 3, a ray detection mechanism, a graphic recognition mechanism, and a sorting execution mechanism. The bottom of the feed bin 1 has a discharge port; the conveyor belt 3 is arranged at the bottom of the feed bin 1, and the conveyor belt 3 is used to convey the ore falling from the feed bin 1; the ray detection mechanism is arranged below the output end of the conveyor belt 3, and is used to perform ray detection on the ore output from the conveyor belt 3 and falling, and feed back the detection result to the controller; the graphic recognition mechanism is arranged below the output end of the conveyor belt 3, and is used to perform photographing detection on the ore output from the conveyor belt 3 and falling, and feed back the detection result to the controller; the sorting execution mechanism is arranged below the ray detection mechanism and the graphic recognition mechanism, and the sorting execution mechanism is used to sort the ore output from the conveyor belt 3 and falling according to the control of the controller.

[0034] For the ore separator provided in this embodiment, only the conveyor belt 3 is used to convey the ore, avoiding the vibration problem of the vibrating feeder. Moreover, since the ray detection mechanism and the graphic recognition mechanism are used together to detect the falling ore, the detection accuracy and screening efficiency of the ore are improved, so that it can better adapt to the conveying speed of the conveyor belt 3.

[0035] As Figure 1 , Figure 2 shown in the figure, in the ore separator provided in this embodiment, there are two conveyor belts 3 symmetrically arranged below the discharge port. Such an arrangement can feed materials on both sides simultaneously, and the length of the conveyor belt 3 is shortened to half of the original, improving the utilization rate of the equipment volume, reducing the floor area of the equipment, increasing the processing capacity of the equipment, improving the efficiency of the equipment, while reducing the installation difficulty of the user enterprise and reducing the installation cost. Of course, the above description is not restrictive. In some alternative embodiments, only one conveyor belt 3 may be provided, or more conveyor belts may be provided according to actual needs, etc.

[0036] As Figure 1 , Figure 2 shown in the figure, in the ore separator provided in this embodiment, a material distributing member 2 is arranged at the bottom of the discharge port of the feed bin 1. The material distributing member 2 has a protruding end extending towards the feed bin 1 and inclined surfaces or arc surfaces symmetrically arranged relative to the protruding end. Such an arrangement cleverly solves the problem of uneven ore supply, enabling the ore to be evenly scattered onto the two conveyor belts 3 on both sides when it falls from the feed bin 1 to the material distributing member 2, thereby improving the uniformity of equipment feeding and increasing the stability of the equipment. Of course, the above description is not restrictive. In some alternative embodiments, the material distributing member 2 may also adopt other conventional structures, such as a drivable material distributing baffle, etc.

[0037] As Figure 1 ,Figure 2 As shown in the figure, in the ore sorter provided in this embodiment, the ray detection mechanism includes a ray source 6 disposed outside the falling trajectory of the ore and a detector 7 disposed inside the falling trajectory of the ore. With such an arrangement, the detector 7 can be set closer to the material, thereby avoiding the problem that the ray attenuates rapidly after passing through the material, resulting in inaccurate reception by the detector 7, and thus improving the accuracy of material sorting. Of course, the above description is not restrictive. In some alternative embodiments, the positions of the ray source 6 and the detector 7 can be swapped. In addition, it should be noted that the ray source 6 in this embodiment can be an X-ray source 6.

[0038] As Figure 1 shown, Figure 2 in the ore sorter provided in this embodiment, the graphic recognition mechanism includes an inner camera 4 disposed inside the falling trajectory of the ore and an outer camera 5 disposed outside the falling trajectory of the ore. With such an arrangement, by taking pictures of the front and back of the ore with the cameras, the external characteristics of the ore are obtained, and then analyzed by the controller, so that the composition of the ore can be obtained. Of course, the above description is not restrictive. In some alternative embodiments, only one of the inner camera 4 and the outer camera 5 can be provided. In addition, it should be noted that the cameras in this embodiment can be high-speed cameras.

[0039] As Figure 1 shown, Figure 2 in the ore sorter provided in this embodiment, a concentrate tank 9 and a waste ore tank 10 are respectively provided below the output end of the conveyor belt 3. With such an arrangement, it can be used to better receive the sorted ore. Of course, the above description is not restrictive. In some alternative embodiments, the concentrate tank 9 and the waste ore tank 10 can be omitted, or replaced by other structures, such as a movable trolley, etc.

[0040] As Figure 1 shown, Figure 2 in the ore sorter provided in this embodiment, the sorting execution mechanism includes a plurality of air nozzles 8 arranged in sequence in the horizontal direction, and the air nozzles 8 are used to sort the falling ore. With such an arrangement, by using the high-pressure gas ejected by the air nozzles 8, the trajectory of the freely falling ore can be changed, so that the sorted ore falls to the corresponding position. Of course, the above description is not restrictive. In some alternative embodiments, the sorting execution mechanism can also adopt other structures, such as an electrically controlled driving push rod, etc.

[0041] As Figure 1 shown, Figure 2As shown in the figure, in the ore sorter provided in this embodiment, the air nozzles 8 are respectively provided with electric control switches, and several of the electric control switches are electrically connected to the controller. With this arrangement, the gas ejected from any one or several of the air nozzles 8 can be accurately controlled according to the control of the controller, so as to accurately drive the freely falling ore. Among them, the electric control switch can be a solenoid valve.

[0042] As Figure 1 , Figure 2 shown in the figure, in the ore sorter provided in this embodiment, the air nozzles 8 have multiple rows arranged in sequence along the height direction. With this arrangement, the aerodynamic force on the ore can be increased to ensure that the ore can fall to the corresponding position. Of course, the above description is not restrictive. In some alternative embodiments, the paint nozzles can also be arranged in only one row, etc.

[0043] As Figure 1 , Figure 2 shown in the figure, in the ore sorter provided in this embodiment, the conveyor belt 3 is horizontally arranged. Since the conveyor belt 3 is horizontally arranged, the overall height of the equipment can be reduced, making the equipment more convenient to install in a lower workshop. Of course, the above description is not restrictive. In some alternative embodiments, the conveyor belt 3 can also be inclined downward or upward towards the conveying end.

[0044] Working principle:

[0045] As Figure 3 shown in the figure, when the ore sorter provided in this embodiment is in use, first, the ore in the silo 1 falls onto the conveyor belts 3 on both sides respectively through the material distributing member 2, and then the ore undergoes free fall at the conveying end after being conveyed by the conveyor belt 3. Since the conveying speed of the conveyor belt 3 is uniform, the trajectory of the freely falling ore is a parabola with a fixed shape. During the free fall of the ore, the ore is combinedly identified by the ray detection mechanism and the image recognition mechanism, and then the controller controls the nozzles of the sorting execution mechanism to blow the ore to change the free fall trajectory of the ore, so that the ore falls into the concentrate tank 9 or the waste ore tank 10.

[0046] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or alterations derived therefrom are still within the protection scope of the present invention.
