[0002] In the sintering production process, in order to enhance the air permeability of the material layer, a material separation plate is arranged at the position where the material pile on the trolley passes, which can create regular gaps in the end face of the sintering material layer, which can reduce the resistance of air extraction at the bottom of the material layer, improve the distribution of air inside the material layer, and improve the air permeability of the material layer; during the use of the material separation plate, due to the nature of the sintering raw materials themselves, part of the raw materials will adhere to the material separation plate. When the thickness of the sticky material reaches a certain level, it will affect the uneven gaps in the material layer and destroy the uniformity of the sintering raw material distribution; at present, the sticky material is cleaned by manually holding a long pole to poke the sticky material off the material separation plate.

The bottom end surface of the scraper 12 is an inclined surface, and the height of the inclined surface close to one end of the connecting rod is greater than the height of the inclined surface away from the one end of the connecting rod. The reason for setting it as an inclined surface is that when the scraper 12 moves downward, when the scraper 12 contacts the material-sparing plate, due to its inclined surface structure, the scraper 12 receives the lateral force pressed by the material-sparing plate on the inclined surface when it moves downward, and pushes the scraper into the vertical column 11 until the material-sparing plate leaves the inclined surface of the scraper, at which time the side wall of the scraper can be in good contact with the material-sparing plate.

[0020] Actual use process: when it is necessary to perform slag removal on the material separator 13, start the hydraulic cylinder to raise the height of the scraper 12 so that it can pass over the trolley, then start the first motor to drive the gear 5 to rotate, thereby driving the long rod 3 to move, and the long rod 3 drives the scraper 12 to move until the first material separation plate is located between the two vertical columns 11. The hydraulic cylinder drives the two scrapers 12 downward. When the material separation plate contacts the inclined surface below the scraper 12, the two scrapers 12 will move away from each other until the distance between the two scrapers 12 is equal to the thickness of the material separation plate. At this time, the scraper 12 is close to the material separation plate. Good contact; then start the second motor to drive the screw nut and the connecting rod to move, and then drive the two scrapers 12 to move along the length direction of the material scavenging plate while touching and pressing the material scavenging plate; in the process of the scraper 12 moving, the sticky material on the material scavenging plate along the way is cleaned up; after the scraper 12 moves to the end, the second motor reverses to drive the scraper 12 to reset, and then the hydraulic cylinder starts to lift the scraper 12, the first motor 6 moves, and drives the long rod 3 forward to the second material scavenging plate, and then repeats the action at the first material scavenging plate until all the material scavenging plates are cleaned.
