DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0029] Embodiment 1

[0030] like Figures 1 to 8 As shown, a graphite boat cleaning device includes a sheet rack 1 and a cleaning pool 2, wherein the sheet rack 1 includes a rectangular frame, a horizontal partition 3, a vertical partition 4 and a bottom support rod, the horizontal partition 3 is a horizontal straight rod connecting the long side frame 5 of the rectangular frame, the vertical partition 4 is a vertical straight rod connecting the upper and lower side horizontal partitions 3, the bottom support rod is a horizontal straight rod connecting the width side frame of the lower side of the rectangular frame, the bottom support rod is close to the lower side of the lower side horizontal partition 3, and there is an adjustment slide 6 on the horizontal partition 3, the adjustment slide 6 is a straight groove concave inward from the upper and lower side horizontal partitions 3 to the opposite side, and the upper and lower ends of the vertical partition 4 are respectively inserted into the upper and lower side adjustment slides 6. The graphite boat to be cleaned is inserted from the upper horizontal partition 3 interval into the corresponding position of the lower horizontal partition 3 interval, and supported by the bottom support rod at the bottom to realize the erection of the graphite boat. The vertical spacer 4 can prevent the graphite boat from being inserted into the side position of the corresponding interval below, that is, it plays a role in guiding the accurate insertion and vertical placement of the graphite boat. When the width of the graphite boat changes, especially when the width of the graphite boat is smaller than the horizontal distance between the vertical spacer 4 and the long frames 5 on both sides, the position of the vertical spacer 4 needs to be adjusted to guide the insertion of the graphite boat. At this time, the vertical spacer 4 can be horizontally slid in the adjustment slot 6 to match the width of the graphite boat and guide the insertion of graphite boats of different widths.

[0031] The long frame 5 is provided with a rod insertion groove for inserting the vertical spacer 4 into the horizontal spacer 3. The rod insertion groove is a through groove extending horizontally inward from the lower edge of the outer side of the long frame 5 to the connecting adjustment slot 6. The outer sides of the corresponding horizontal spacers 3 can be provided with rod insertion grooves, and the number of vertical spacers 4 can be increased or decreased in the adjustment slot 6 through the rod insertion grooves to ensure the stability of the graphite boat sheet insertion process.

[0032] It also includes a limiting portion for limiting the horizontal position of the vertical partition bar 4 on the transverse partition bar 3.

[0033] The limiting portion includes a diverging plate 7, a positioning groove 8 and an upper wide groove 9. The diverging plate 7 is an inclined plate extending diagonally outward from the rod surface at the upper and lower ends of the vertical partition rod 4. The positioning groove 8 is an inclined groove extending diagonally outward from the side wall of the adjusting slide groove 6. The positioning groove 8 is divided into intervals on the adjusting slide groove 6. The upper wide groove 9 is a straight groove extending in the opposite direction from the upper edge of the groove wall surface on both sides of the upper adjusting slide groove 6. The cross-sectional shape of the upper wide groove 9 and the adjusting slide groove 6 is like a T shape. When the vertical partition rod 4 naturally contacts the surface of the bottom support rod, the divergent plates 7 on the upper and lower sides are inserted into the upper and lower positioning grooves 8. When the vertical partition rod 4 needs to be moved, the vertical partition rod 4 is pushed up vertically so that the divergent plates 7 on the upper and lower sides are disengaged from the positioning grooves 8, wherein the upper divergent plate 7 enters the upper wide groove 9, and the lower divergent plate 7 is located above the lower adjustment slide groove 6, and is translated in the adjustment slide groove 6 through the rod body of the vertical partition rod 4. When the horizontal position adjustment is completed, the vertical partition rod 4 is vertically lowered again, and the divergent plate 7 is automatically inserted into the positioning groove 8 corresponding to the current position.

[0034] There is also an operation slot 10 on the vertical partition rod 4, which is a vertical slot horizontally penetrating the vertical partition rod 4. The operation slot 10 not only increases the roughness of the shaft of the vertical partition rod 4, which is conducive to pushing and translating the vertical partition rod 4, but also plays a role in clarifying the direction of the divergent plate 7.

[0035] The operation slot 10 also includes an interference adjustment plate 11, which is a flat plate inserted in the operation slot 10. When a plurality of vertical partitions 4 are arranged at intervals in the adjustment slot 6, the interference adjustment plate 11 can be pushed out of the operation slot 10, so that the gap between the edge of the interference adjustment plate 11 in the extension direction and the adjacent vertical partitions 4 is adjusted. In order to make the interference adjustment plate 11 easier to identify, the upper and lower edges are shortened in the figure. In practical applications, the operation slot 10 can be designed by calculation to be just close to the upper and lower edges of the horizontal partition 3 when the interference adjustment plate 11 is extended. At this time, the wavelength of the emitted sound wave is adjusted and unified in cooperation with the ultrasonic transducer in the cleaning tank, so that ultrasonic interference occurs when the ultrasonic wave passes through the gap between the interference adjustment plate 11 and the vertical partition 4, thereby more effectively cleaning the surface of the graphite boat sheet.

[0036] The utility model also comprises a thickness adjusting portion for adjusting the spacing distance between the diaphragms.

[0037] The thickness adjustment part includes a shallow transverse groove, a through transverse groove 12 and a width selection block. The shallow transverse groove is a horizontally extending groove that is recessed inward from the inner surface of the long frame 5 on one side. The through transverse groove 12 is a through groove that horizontally penetrates the long frame 5 on the other side. The two ends of the transverse bar 3 are respectively inserted into the shallow transverse groove and the through transverse groove 12. The width selection block includes a narrow push block 13 and a wide push block 14. The narrow push block 13 and the wide push block 14 are vertically stacked and mounted on the outside of the through transverse groove 12. The transverse bar 3 can be translated in the shallow transverse groove and the through transverse groove 12 to push the narrow push blocks 13 or wide push blocks 14 of different widths into the adjacent transverse bar 3, thereby changing the gap between adjacent transverse bars 3, matching graphite boats of different thicknesses or achieving stable extrusion of the graphite boats. In particular, by changing the gap between the transverse bars 3 to drive the gap between adjacent graphite boats, ultrasonic interference is formed in the spacing direction of the graphite boats, which can achieve a better ultrasonic cleaning effect. At this time, the rod insertion groove can only be set at one place. When the number of vertical partition rods 4 needs to be changed, the horizontal partition rod 3 can be translated to the rod insertion groove, and the vertical partition rod 4 can be pushed into the adjustment slide groove 6.
