[0057] Please see Figures 1 to 10 This utility model provides a sagger cleaning device, such as... Figure 1 As shown, the sagger cleaning device includes a drive mechanism 1 and a cleaning component 2. The drive mechanism 1 includes a drive shaft 11 and a driven shaft 12, which are arranged in parallel. The drive shaft 11 and the driven shaft 12 are connected by a connector 3, and the driven shaft 12 is configured to rotate around the drive shaft 11 under the transmission action of the drive shaft 11. The cleaning component 2 is mounted on the driven shaft 12. The cleaning component 2 has a cleaning section at its distal end along the radial direction of the driven shaft 12.

[0058] With the cooperation of the drive shaft 11, driven shaft 12 and cleaning component 2, the drive shaft 11 drives the driven shaft 12 to rotate, and the driven shaft 12 rotates around the drive shaft 11, so that the cleaning part at the far end of the cleaning component 2 installed on the driven shaft 12 forms a square cleaning area, which can effectively clean the square crucible 6 and reduce material residue.

[0059] Specifically, the sagger 6 is a square box used to fill graphite carbide material. The side length of the sagger 6 is the first length L1. The distance between the central axis of the drive shaft 11 and the central axis of the driven shaft 12 is the second length L2. A scraper edge 211 is provided at the end of the cleaning part away from the driven shaft 12. The distance from the scraper edge 211 to the central axis of the driven shaft 12 is the third length L3. The sagger cleaning device is arranged such that the central axis of the driving shaft 11 coincides with the central axis of the sagger 6, and the line connecting the scraping edge 211 and the central axis of the driven shaft 12 passes through the central axis of the driving shaft 11. By coinciding the central axis of the driving shaft 11 of the sagger cleaning device with the central axis of the sagger 6 and limiting the distance of the scraping edge 211 to the central axis of the driven shaft 12, the scraping edge 211 can clean the material in the sagger 6 to the maximum extent, so that the material in the sagger 6 is discharged as much as possible.

[0060] Taking a square box sagger with a side length of 40 cm as an example, without considering the scratching between the scraping edge 211 and the square box sagger 6, the positional relationship between the sagger 6 and the sagger cleaning device is described in detail, as shown in Figure 9 and Figure 10 When the sagger 6 is cleaned, the central axis of the driving shaft 11 of the sagger cleaning device coincides with the central axis of the sagger 6, the side length of the sagger 6 is 40 cm, i.e. L1=40 cm, the distance between the central axis of the driving shaft 11 of the sagger cleaning device and the central axis of the driven shaft 12 is the second length L2, the diameters of the driving shaft 11 and the driven shaft 12 are both 1 cm, the distance between the central axis of the driving shaft 11 and the central axis of the driven shaft 12 is 3 cm, i.e. L2=3 cm, and then the distance between the scraping edge 211 at the end of the cleaning part and the central axis of the driven shaft 12 is the third length L3=23 cm.

[0061] Under the driving action of the driving shaft 11, when the driven shaft 12 rotates circumferentially around the driving shaft 11, the cleaning track formed by the scraping edge 211 is similar to a square shape, as shown in Figure 9 The figure shows a schematic diagram of the cleaning track formed by the scraping edge 211, and the similar square dashed line in the figure shows the cleaning track formed by the scraping edge 211, and the center of the cleaning track coincides with the central axis of the driving shaft 11. As shown in Figure 10 The figure shows the movement track of the driven shaft 12, the center of gravity of the triangle in the figure coincides with the central axis of the driven shaft 12, and the dashed circle in the figure is the movement track formed by the circumferential rotation of the driven shaft 12 around the driving shaft 11.

[0062] Combined with Figures 1 to 8 Further, in this embodiment, the cleaning part 2 includes at least one scraping blade 21, the scraping blade 21 has a scraping edge 211, and the scraping blade 21 is fixedly connected to the driven shaft 12. In this application, three scraping blades 21 are provided, and the size of the scraping blade 21 can be determined according to the size of the sagger 6. Taking the side length of the sagger 6 as 42 cm as an example, the steps of setting the size of the scraping blade 21 are described in detail. The scraping blade 21 provided here can be a hard scraper. In order to avoid the contact and scratching between the tip of the scraper and the inner wall of the sagger 6, a certain distance can be left between the scraper and the wall of the sagger 6, as shown in Figures 5 to 8In the present application, the length and width of the rotating track of the scraping blade 21 can be set to 40 cm. Therefore, an equilateral triangle B with a side length of 40 cm can be made inside the square A with a side length of 40 cm as shown in the drawing. The three vertices of the equilateral triangle B are a, b and c respectively, and the center d of the equilateral triangle B. Three circles are made with the vertices of the equilateral triangle B as the centers and the radii as the side length. The arc edges formed by the vertices of the equilateral triangle B and the circles are retained to obtain the shape as shown in the drawing. The shadow part as shown in the drawing is cut on the basis of the drawing, and finally the edge shape of the scraping blade 21 is obtained as shown in the drawing. The shadow area to be cut can be selected according to the actual situation, or it can be selected not to be cut, and a complete shape is selected as the scraping blade 21.
