[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0022] like Figure 1-4 As shown, the utility model proposes a cleaning device for a feeder for heavy alkali production, comprising a furnace body 1, wherein a scraper 2 is horizontally movable inside the furnace body 1 and is in contact with the inner wall of the furnace body 1, a first slide bar 51 is vertically fixed inside the furnace body 1, a threaded rod 52 is rotatably installed at the bottom of the furnace body 1 parallel to the first slide bar 51, and the upper end of the threaded rod 52 is connected to the power of a motor 521 outside the furnace body 1; the scraper 2 is slidably sleeved on the first slide bar 51 up and down and is threadedly sleeved on the threaded rod 52. When the motor 521 drives the threaded rod 52 to rotate, under the guidance of the first slide bar 51, the scraper 2 can slide up and down close to the inner wall of the furnace body 1 to achieve the scraping of adhered accumulated materials.

[0023] A rotating ring 3 is installed horizontally and rotatably below the scraper 2. The first slide bar 51 and the threaded rod 52 pass vertically through the middle of the rotating ring 3 without affecting the horizontal rotation of the rotating ring 3. A rotating shaft 8 is rotatably installed in the vertical through hole on the scraper 2. A first gear 81 is coaxially fixed below the rotating shaft 8. A gear ring 31 is provided on the inner ring of the rotating ring 3. The first gear 81 meshes with the gear ring 31. The rotational power of the threaded rod 52 is transmitted to the rotating shaft 8 through the transmission assembly. A plurality of scrapers 4 are arranged on the outer edge of the circular arc of the rotating ring 3. The rotational power transmission assembly of the threaded rod 52 is transmitted to the rotating shaft 8, and the cooperation of the first gear 81 and the gear ring 31 drives the rotating ring 3 to rotate, so that the scraper 4 on the outer edge of the rotating ring 3 rotates and scrapes off the accumulated material on the inner wall of the furnace body 1.

[0024] Specifically, the transmission assembly includes a sleeve 6, a gear transmission assembly, a second gear 82 and a third gear 61. The sleeve 6 is movably mounted on the threaded rod 52 and its lower end is rotatably connected to the scraper 2. A slide groove 520 is provided on the threaded rod 52 along its length direction. A protrusion is fixed on the inner wall of the sleeve 6, and the protrusion is slidably clamped in the slide groove 520. A second gear 82 is coaxially fixed above the rotating shaft 8, and a third gear 61 is coaxially fixed on the sleeve 6. The gear transmission assembly is installed between the second gear 82 and the third gear 61. The gear transmission assembly includes a transmission shaft 7, which is horizontally mounted on the scraper 2, and the meshing teeth 71 fixed at both ends thereof are vertically meshed with the second gear 82 and the third gear 61 respectively. Among them, the meshing teeth 71, the second gear 82 and the third gear 61 are all bevel gears. When the threaded rod 52 rotates to drive the scraper 2 to move up and down, the sleeve 6 will move up and down with the scraper 2, and through the cooperation between the protrusion in the sleeve 6 and the slide groove 520, the sleeve 6 will be driven to rotate synchronously with the threaded rod 52 in the horizontal direction, and then the two meshing teeth 71 will be vertically meshed with the second gear 82 and the third gear 61 respectively, and the power will be transmitted to the rotating shaft 8 through the transmission shaft 7, thereby realizing the driving of the rotating ring 3. There is no need to set up multiple driving sources, and the power transmission efficiency is higher.

[0025] One end of the scraper 4 is hinged on the rotating ring 3, and the other end is in contact with the inner wall of the furnace body 1 through an elastic support. The scraper 4 is tilted against the inner wall of the furnace body 1, and the angle between the scraper 4 and the inner wall of the furnace body 1 is an obtuse angle. A support rod 94 is tilted on the side of the scraper 4 close to the rotating ring 3. One end of the support rod 94 is hinged on the rotating ring 3, and the other end is hinged on the moving block 93. A second slide bar 91 is fixed on the side of the scraper 4 away from the furnace body 1. The moving block 93 is slidably mounted on the second slide bar 91. A spring 92 is mounted on the slide bar. The spring 92 presses the moving block 93 against the inner wall of the furnace body 1. Under the elastic force of the spring 92, the moving block 93 will be pressed against and moved away from the rotating ring 3, thereby causing the support rod 94 to rotate and swing, and the scraper 4 is rotated and lifted up, so that the scraper 4 effectively abuts against the inner wall of the furnace body 1, and the scraping effect is better.

[0026] The scraper 4 includes a blade body 41 and a blade head 42. The blade body 41 is hinged on the ring, and the second slide bar 91 is also installed on the blade body 41. A mounting groove is provided at the end of the blade body 41, and the blade head 42 is clamped in the mounting groove. The blade head 42 abuts against the inner wall of the furnace body 1. Bolts 43 are installed on the side wall of the blade body 41, and the bolts 43 extend into the mounting groove and are crimped and fixed with the blade head 42. As the cleaning operation time accumulates, when the blade head 42 of the scraper 4 is severely worn and needs to be replaced, the blade head 42 can be removed from the mounting groove and replaced with a new blade head 42, and the bolts 43 are used to abut and fix it, so that the replacement operation of the blade head 42 is simpler and more convenient.

[0027] When the utility model is used, when the motor 521 drives the threaded rod 52 to rotate, it will drive the scraper 2 to move up and down close to the inner wall of the furnace body 1 to perform up and down scraping operations. The rotational power of the threaded rod 52 is transmitted to the rotating ring 3 through the sliding sleeve 6, the gear transmission assembly, and the rotating shaft 8, and then the scraper 4 is driven to rotate through the rotation of the rotating ring 3. The scraper 4 is abutted against the inner wall of the furnace body 1 through the elastic support member to rotate and scrape the material, thereby achieving a better cleaning effect.
