The number of positioning blocks 407 is set to be several and symmetrical along the vertical center axis of the positioning plate 406. The design of the block 409 can make the slide plate 411 in a fixed state when the device is working. A spring 410 is fixedly connected to the side of the block 409. The end of the spring 410 away from the block 409 is fixedly connected to the side of the positioning plate 406. By adjusting the position of the pull rope 404 and the block 409, the movement of the scraper 401 and the opening of the discharge port can be flexibly controlled, so as to adapt to different refining requirements and furnace conditions, and enhance the adaptability of the equipment. The initial state of the spring 410 is a relaxed state. The mounting block 403 is located on the motion track of the extrusion block 402. The design of the spring 410 can make the block 409 automatically reset, reducing manual intervention and improving the flexibility of the device.

[0026] In this embodiment, when the device is calcined, the pull rope 404 is pulled, and the installation block 403 is moved by the pull rope 404, so that the installation block 403 is moved to the inner wall of the slide plate 411, and then the installation plate 405 is moved to the inside of the rectangular block 412. At this time, the block 409 is squeezed, so that the block 409 drives the round rod 408 to rotate, and the spring 410 on the side of the block 409 is squeezed. When the block 409 is displaced to the slot on the side of the rectangular block 412, the block 409 is reset by the elastic force of the spring 410, so that the block 409 is stuck in the slot. At this time, the slide plate 411 is fixed. When the device is calcined, the block 409 is pressed inwards to The clamping block 409 is retracted into the rectangular block 412, and the pull rope 404 is pulled to disengage the clamping block 409 from the rectangular block 412. At this time, the mounting block 403 is located on the inner wall of the slide plate 411, and the rotation of the rotating shaft 309 drives the scraper 401 to rotate.
