[0014] This utility model provides, for example Figure 1-4 The material cleaning device for blast furnace fuel conveying shown includes a support platform 1, a conveyor belt 2 installed on the upper end of the support platform 1, a dust suppression curtain and dust collection equipment installed on the outside of the conveyor belt 2, a detector 3 installed on one side of the conveyor belt 2, the detector 3 can detect the thickness of the material on the conveyor belt 2 and the temperature of the conveyor belt 2, a high-pressure airflow purging device 4 installed on one side of the detector 3, the high-pressure airflow purging device 4 can blow up the surface floating material on the conveyor belt 2, a drive frame 5 installed on one side of the high-pressure airflow purging device 4, a scraper 6 installed on the front side of the drive frame 5, the drive frame 5 can adjust the position of the scraper 6, and the scraper 6 can scrape off the stubborn sticky material on the conveyor belt 2.

[0015] The material cleaning process of this device is as follows: the material is moved by the conveyor belt 2. When the material moves to the end of the conveyor belt 2 and is discharged, the thickness of the residual material on the conveyor belt 2 and the temperature of the conveyor belt 2 are detected by the detector 3. Then, the high-pressure airflow blowing device 4 is activated to blow up the floating material on the conveyor belt 2. The floating material can be collected by the dust collection equipment. The position of the scraper 6 is adjusted by the drive frame 5, and then the stubborn sticky material on the conveyor belt 2 can be scraped off.

[0016] Refer to the instruction manual appendix Figure 1 The detector 3 includes a millimeter-wave radar 7 installed on the support platform 1. A temperature sensor 8 is installed on one side of the millimeter-wave radar 7. The temperature sensor 8 can detect the temperature on the conveyor belt 2. The thickness of the material on the conveyor belt 2 can be detected by the millimeter-wave radar 7 and the temperature on the conveyor belt 2 can be detected by the temperature sensor 8.

[0017] Refer to the instruction manual appendix Figure 1 The high-pressure airflow purging device 4 includes a high-pressure blower 9 installed on one side of the conveyor belt 2. An air outlet pipe 10 is installed at the outlet end of the high-pressure blower 9, and the outlet end of the air outlet pipe 10 points to the conveyor belt 2. When the high-pressure blower 9 is started, the air blown out by the high-pressure blower 9 can be discharged onto the conveyor belt 2 through the air outlet pipe 10, which can facilitate the blowing up of floating materials.

[0018] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4 The drive frame 5 includes a first electric telescopic rod 11 installed on the upper end of the support platform 1. A moving platform 12 is installed at the telescopic end of the first electric telescopic rod 11. Multiple electric grippers 13 are installed on the front side of the moving platform 12. The scraper 6 is located on the front side of the moving platform 12, and the electric grippers 13 hold the scraper 6.

[0019] The process of the drive frame 5 moving the scraper 6 is as follows: the electric gripper 3 can easily clamp and release the scraper 6, which makes it easy to replace the scraper 6. By extending and retracting the first electric telescopic rod 11, the position of the scraper 6 can be easily adjusted.

[0020] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4 The front side of the moving platform 12 has multiple limiting holes 14. One end of the scraper 6 is equipped with a limiting rod 15, which extends into the limiting hole 14. The limiting rod 15 and the limiting hole 14 are connected by a telescopic spring 16. A fixed platform 17 is installed on the upper end of the support platform 1. A second electric telescopic rod 18 is installed on the upper end of the fixed platform 17. A limiting roller 19 is installed on the telescopic end of the second electric telescopic rod 18. The limiting roller 19 can move to the front side of the scraper 6.

[0021] The process of adjusting the position of the scraper 6 is as follows: Under normal conditions, the first electric telescopic rod 11 is retracted to its shortest length, and then the second electric telescopic rod 18 is extended, causing the limiting roller 19 to move to the front of the scraper 6. Then, the first electric telescopic rod 11 is extended to a fixed length. If the scraper 6 is not worn, at this point, the scraper 6 is in contact with the limiting roller 19. Then, the second electric telescopic rod 18 is retracted, which can move the limiting roller 19 to the outside of the scraper 6. The rotation of the limiting roller 19 reduces the frictional force during its movement. If the scraper 6 has become worn after a period of use, this... At this time, there is a gap between the scraper 6 and the limiting roller 19. At this time, the electric gripper 13 is first released. Under the elastic force of the telescopic spring 16, the scraper 6 can be pushed outward. The limiting hole 14 and the limiting rod 15 can ensure the movement direction of the scraper 6, so that the scraper 6 can contact the limiting roller 19. Then, the scraper 6 is clamped by the electric gripper 13. The second electric telescopic rod 18 is activated to shorten, so that the limiting roller 19 can move to the side of the scraper 6. Then, the first electric telescopic rod 11 is activated to extend, so that the scraper 6 can move to the side of the conveyor belt 2, so that the material can be scraped off easily.
