Description
Technical Field
[0001] The utility model relates to the field of color sorting devices, in particular to a color sorting device for quartz sand purification. Background Art
[0002] A color sorter is a device that automatically sorts out different-colored particles in granular materials based on the differences in the optical properties of the materials. In the process of processing quartz sand, a purification color sorting device is often used. Its principle is to capture the image information of the falling quartz sand through a high-speed camera, evaluate the defective materials by analyzing the color, shape, and size of the image, and feedback to multiple high-pressure air nozzles to blow out the defective materials by spraying.
[0003] In the prior art, the current quartz sand purification color sorting device usually uses multiple color sorters in combination, and the color sorters are usually installed on a platform rack.

[0034] In order to make the utility model purpose, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present utility model.
[0035] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be intermediate components present at the same time.
[0036] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.
[0037] As Figures 1 to 6 shown, an embodiment of the present utility model provides a quartz sand purification color sorter, which includes a platform frame 3, a first color sorter 1 and a second color sorter 2. The first color sorter 1 and the second color sorter 2 are relatively arranged on the platform frame 3. By setting two color sorters, more quartz sand can be processed simultaneously, thereby improving the color sorting efficiency of quartz sand. Moreover, setting two color sorters can be used as a backup. When one device fails, the other can continue to work to ensure that the production line will not stop due to equipment failure.
[0038] The first color sorter 1 and the second color sorter 2 have the same structure. The first color sorter 1 includes a frame 11, a feeding hopper 12, a guiding chute 13, a CCD camera 14, a jet nozzle 15, a first discharge hopper 16 and a second discharge hopper 17. The frame 11 is arranged on the platform frame 3. The feeding hopper 12 is arranged on the top of the frame 11 and is used to receive the quartz sand to be purified. The guiding chute 13 is obliquely arranged below the feeding hopper 12. The first discharge hopper 16 and the second discharge hopper 17 are arranged in parallel at the bottom of the guiding chute 13, and the first discharge hopper 16 is located on the side close to the guiding chute 13. The quartz sand falling from the feeding hopper 12 falls into the first discharge hopper 16 through the guiding chute 13. In this embodiment, the first discharge hopper 16 is used to convey the qualified quartz sand, and the second discharge hopper 17 is used to convey the defective quartz sand.
[0039] Along the width direction of the guiding chute 13, a plurality of the CCD cameras 14 are respectively arranged on both sides of the first discharge hopper 16 and the second discharge hopper 17. A plurality of the jet nozzles 15 are arranged at intervals on the side end of the first discharge hopper 16 away from the second discharge hopper 17. The CCD camera 14 is used to collect the image information of the quartz sand falling from the guiding chute 13 into the first discharge hopper 16. The jet nozzle 15 is used to blow the quartz sand falling into the first discharge hopper 16 into the second discharge hopper 17. When the CCD camera 14 detects that the quartz sand particles in the falling motion state meet the measurement requirements, the jet nozzle 15 does not act, and at this time, the quartz sand is discharged and conveyed from the first discharge hopper 16. When the CCD camera 14 detects that the quartz sand particles in the falling motion state do not meet the measurement requirements, the control system can drive the jet nozzle 15 to eject high-pressure air flow to blow these defective quartz sand particles into the second discharge hopper 17, so as to realize the sorting and purification of quartz sand.
[0040] The second discharge hoppers 17 of the first color sorter 1 and the second color sorter 2 are arranged oppositely. There is a discharge port 30 on the platform frame 3, and the discharge port 30 is located below the two second discharge hoppers 17.

There are several diversion holes 120 on the side wall of the bottom of the feed hopper 12 close to the diversion plate 18. The diversion holes 120 are used to divert and convey the quartz sand. The diversion holes 120 can control the flow rate and distribution of the quartz sand to ensure that the quartz sand can enter the guide chute 13 evenly, improving the working efficiency and accuracy of the color sorter. The inclined diversion plate 18 can guide and convey the quartz sand flowing out of the feed hopper 12 and direct it onto the guide chute 13 in an orderly manner, effectively reducing the accumulation and blockage of the quartz sand.
[0042] As Figure 3 and Figure 4 shown, further, there are several arc-shaped chutes 131 arranged in parallel at intervals on the guide chute 13. The arc-shaped chutes 131 are used to divert and convey the quartz sand falling from the guide chute 13. There is a baffle plate 132 at the top of the guide chute 13, and the baffle plate 132 abuts against the surface of the arc-shaped chute 131 to make the quartz sand slide down from within the arc-shaped chute 131, avoiding the concentrated accumulation and sliding of the quartz sand material. The arc-shaped chutes 131 can divert and convey the quartz sand falling from the guide chute 13, preventing the quartz sand from deviating from the track during the sliding process and maintaining the stability of the flowing and conveying of the quartz sand.
[0043] As Figure 1 shown, further, it further includes a conveyor belt (not shown). The conveyor belt is arranged below the discharge port 30, and the conveyor belt is used to receive and convey the quartz sand falling from the second discharge hopper 17. As a conveying device, the conveyor belt can receive and transfer the defective quartz sand falling from the second discharge hopper 17 to move the defective quartz sand along a specific path and convey it to the next processing stage or equipment.

The second mounting arm 102 is arranged below the first mounting arm 101 and is arranged at one side end of the first discharge hopper 16 close to the material guiding groove 13. The air nozzle 15 is arranged on the second mounting arm 102. The first mounting arm 101 and the second mounting arm 102 can be used to support and position the CCD camera 14 and the air nozzle 15 to ensure the stability of the CCD camera 14 and the air nozzle 15 during the color sorting process.
