[0021] The following will describe the implementation of the present application in detail with reference to the accompanying drawings and examples.
[0022] See also Figure 1~2 The broken glass screening device includes a silo 4, a screening mechanism, a conveying mechanism and a material separation mechanism. The silo 4 is fixed on the top of the screening mechanism through a silo support frame 3. In order to control the feeding, a feeder 5 is fixedly installed at the discharge port of the silo 4 through a connecting rod 18. The feeder 5 can be an electromagnetic feeder. The broken glass is evenly scattered on the screening mechanism through the electromagnetic feeder. Among them, the silo 4 is 4.2 meters long, 2.5 meters wide and 1.5 meters deep. Considering the height of the forklift, the forklift feeds the material in a side manner. The feeding end of the conveying mechanism is set directly below the large-particle broken glass discharge port of the screening mechanism. The large-particle broken glass screened by the screening mechanism is continuously transported by the conveying mechanism. The material separation mechanism is set at the discharge end of the conveying mechanism to change the direction of the broken glass transported by the conveying mechanism, thereby separating the broken glass with non-ferrous metals from the broken glass without non-ferrous metals.
[0023] Among them, the screening mechanism for screening broken glass includes a screen 6 and a vibration motor 7. The screen 6 is fixed to the bottom of the feeder 5 through a connecting rod 18, and the vibration motor 7 is fixedly installed on the screen 6. When in use, the vibration motor 7 is started to drive the screen 6 to vibrate, thereby screening out the ultra-fine broken glass and iron filings on the screen 6.
[0024] The conveying mechanism includes a conveying support frame 1, on which a conveyor belt 2 is rotatably arranged. A driving motor 9 for driving the conveyor belt 2 to rotate is installed on the conveying support frame 1. One end of the conveyor belt 2 is directly below the discharge port of large-particle broken glass of the screen 6. A metal detector 12 is fixed on the conveying support frame 1, and the detection end of the metal detector 12 is arranged above the conveyor belt 2.
[0025] In order to prevent broken glass from falling onto the conveyor belt 2 and splashing, a feed hopper 8 is fixedly installed at one end of the conveyor support frame 1 close to the screen 6, and the discharge port of the feed hopper 8 is above the conveyor belt 2. In order to quickly remove iron particles mixed in the broken glass, an iron remover 11 is fixedly installed on the conveyor support frame 1, and the iron suction end of the iron remover 11 is arranged above the conveyor belt 2. In order to further improve the iron removal effect, a strong magnetic rod 10 is fixedly installed on the conveyor support frame 1, and the strong magnetic rod 10 is located between the feed hopper 8 and the iron remover 11. In order to increase the iron removal area, the conveyor belt 2 is a leather conveyor belt, and the rollers used to support the conveyor belt 2 are straight rollers.
[0026] In this embodiment, the material separation mechanism for separating the broken glass with non-ferrous metals from the broken glass without non-ferrous metals includes a material separation flap 16 and a cylinder 17. The end of the conveying support frame 1 away from the screen 6 is fixedly connected to the bracket 15. The material separation flap 16 is rotatably connected to the bracket 15. One end of the cylinder 17 is hinged to the bracket 15. The piston rod end of the cylinder 17 is hinged to one side of the material separation flap 16. A waste box 13 and a finished broken glass box 14 are provided below the material separation flap 16. The waste box 13 and the finished broken glass box 14 are arranged side by side along the swing direction of the material separation flap 16. The metal detector 12 is electrically connected to the signal input end of the PLC controller, and the cylinder control valve of the cylinder 17 is controlled by the PLC controller.
[0027] When the metal detector 12 detects that the broken glass contains non-ferrous metals, it sends a signal to the PLC controller, and the PLC controller controls the cylinder control valve, and then controls the extension of the piston rod of the cylinder 17, thereby driving the material distribution flap 16 to rotate, and discharges the broken glass with non-ferrous metals into the waste box 13. When the metal detector 12 does not detect non-ferrous metals, the PLC controller controls the cylinder control valve, and then controls the piston rod of the cylinder 17 to retract, so that the broken glass without non-ferrous metals is discharged into the finished broken glass box 14.
[0028] In order to avoid losing broken glass containing non-ferrous metals, the conveying length of the conveyor belt 2 is 10m, and the distance between the metal detector 12 and the material separation flap 16 is 5m-6m. Considering that there are multiple broken glasses containing non-ferrous metals within this distance, the PLC S7-200 is used to store the number of non-ferrous metals measured by the metal detector 12, and control the cylinder 17 to drive the material separation flap 16 to remove part of the broken glass containing non-ferrous metals to prevent the loss of the number of non-ferrous metals.
[0029] In this embodiment, the electrical control fully considers interlocking, and the feeder 5, the vibration motor 7, and the drive motor 9 are controlled in a reverse start and forward stop manner to prevent a failure of one of the sections from causing congestion in the broken glass transportation process.
[0030] When in use, the forklift pours the broken glass into the silo 4, and the broken glass is evenly scattered onto the screen 6 through the feeder 5, and then the vibration motor 7 is started to screen out the ultrafine powder (containing iron powder) in the broken glass. The large particles of broken glass enter the flat conveyor belt 2, pass through the strong magnetic rod 10 and the iron remover 11 to remove the larger iron blocks, and then after being detected by the metal detector 12, the PLC controller controls the cylinder 17 to cooperate with the material separation flap 16 to separate the broken glass containing non-ferrous metals from the broken glass without non-ferrous metals, so as to achieve the effect of removing non-ferrous metals.
