Specific embodiments

[0031] The following will Figures 1-3 further elaborate on this application in conjunction with the attached drawings.

[0032] An embodiment of this application discloses a rotating bowl cleaning device. Referring to Figure 1 , it includes a protective housing 1, a drive motor 2, a transmission mechanism 3, an auxiliary shaft 4, a support platform 5, and a placement cylinder 6. Among them, both the auxiliary shaft 4 and the drive motor 2 are installed on the protective housing 1, and the rotating shafts of the auxiliary shaft 4 and the drive motor 2 both extend from above the protective housing 1. The extended parts are respectively connected to the transmission mechanism 3, and the transmission mechanism 3 acts on the lower part of the support platform 5. The drive motor 2 drives the support platform 5 to swing through the transmission mechanism 3. During this process, the auxiliary shaft 4 can cooperate with the transmission mechanism 3 to support the support platform 5; the placement cylinder 6 is fixed above the support platform 5 and is used to place the rotating bowl 9 to be cleaned.

[0033] Place the rotating bowl 9 into the placement cylinder 6, add cleaning liquid or solution to the rotating bowl 9, use the drive motor 2 to drive the support platform 5 to swing, and at the same time, use the auxiliary shaft 4 to support the support platform 5. The swing of the support platform 5 drives the rotating bowl 9 in the placement cylinder 6 to swing synchronously, so that the cleaning liquid or solution in the rotating bowl 9 rotates in the rotating bowl 9, thereby using the cleaning liquid or solution to wash away the substances adhering to the inner wall of the rotating bowl 9 and finally mixing them into the cleaning liquid or solution to achieve the cleaning of the inner wall of the rotating bowl 9.

[0034] To improve the stability of the support platform 5 during the swinging process, two auxiliary shafts 4 are provided, and the two auxiliary shafts 4 and the rotating shaft of the drive motor 2 are distributed in an equilateral triangle, making the support and fixation of the transmission mechanism 3 on the support platform 5 more stable.

[0035] Specifically, referring to Figure 2 , the transmission mechanism 3 includes a fixed shaft 31 and a swing arm 32. The rotating shaft of the drive motor 2 and the auxiliary shaft 4 respectively pass through the swing arm 32 and are fixedly connected to one end of the swing arm 32. The other end of the swing arm 32 is fixedly connected to the fixed shaft 31, and the fixed shaft 31 vertically passes through the support platform 5 and rotates relative to the support platform 5.

[0036] When the driving motor 2 drives the supporting platform 5 to swing, the rotating shaft of the driving motor 2 acts on the swing arm 32, driving the swing arm 32 to rotate, and then driving the fixed shaft 31 to make a circular motion around the rotating shaft. With the support of the auxiliary shaft 4, the swing of the supporting platform 5 is realized.

[0037] Refer to Figure 2 and Figure 3 Above the supporting platform 5, a first fixing plate 7 is fixed. The upper end of the fixed shaft 31 extends out from the top of the supporting platform 5 and is located inside the first fixing plate 7. A bearing 74 is installed between the first fixing plate 7 and the fixed shaft 31, and an elastic retaining ring 72 is used to limit the outer ring of the bearing 74 to realize the installation of the fixed shaft 31.

[0038] Above the protective housing 1, a second fixing plate 8 is fixed. One end of the auxiliary shaft 4 far from the swing arm 32 is located inside the second fixing plate 8. And a bearing 74 is installed between the second fixing plate 8 and the auxiliary shaft 4, and an elastic retaining ring 72 is used to limit the outer ring of the bearing 74 to realize the installation of the auxiliary shaft 4.

[0039] Among them, the installation and positioning method of the bearing 74 between the first fixing plate 7 and the fixed shaft 31 is the same as that of the bearing 74 between the second fixing plate 8 and the auxiliary shaft 4. Here, the installation of the bearing 74 between the first fixing plate 7 and the fixed shaft 31 is taken as an example for explanation.

[0040] Specifically, the bearing 74 is sleeved on the fixed shaft 31. The outer peripheral wall of the outer ring of the bearing 74 abuts against the inner wall of the first fixing plate 7, and the inner peripheral wall of the inner ring of the bearing 74 abuts against the outer wall of the fixed shaft 31. A ring groove 71 is circumferentially formed on the inner wall of the first fixing plate 7. The elastic retaining ring 72 can be clamped in the ring groove 71. At the same time, the elastic retaining ring 72 abuts against one end of the outer ring of the bearing 74 far from the supporting platform 5. Through the vertical limit of the bearing 74 by the elastic retaining ring 72 and the circumferential limit of the inner wall of the first fixing plate 7, the fixing of the bearing 74 in the first fixing plate 7 is realized.

[0041] At the same time, the first fixing plate 7 is provided with a plurality of fixing holes 73 in the vertical direction. The plurality of fixing holes 73 are evenly distributed around the axis of the first fixing plate 7. Bolts can be used to pass through the fixing holes 73 to fix the first fixing plate 7 above the supporting platform 5.

[0042] Further, the swing arm 32 is horizontally arranged, and a plurality of adjustment holes 321 for inserting and fixing the fixed shaft 31 are formed in the swing arm 32 in the vertical direction, and the adjustment holes 321 are sequentially arranged on the swing arm 32 in the direction perpendicular to the axis of the fixed shaft 31; when it is necessary to adjust the swing amplitude of the support platform 5, the fixed shaft 31 can be taken out from the original adjustment hole 321 and inserted into other adjustment holes 321 at the corresponding positions to adjust the size of the rotation radius of the fixed shaft 31, thereby controlling the swing amplitude of the support platform 5; when the distance between the fixed shaft 31 and the auxiliary shaft 4 or the rotating shaft of the driving motor 2 is closer, the rotation radius of the fixed shaft 31 is smaller, and the swing amplitude of the cleaning liquid or solution in the rotating bowl 9 is lower.

[0043] Meanwhile, a plurality of locking holes 322 are formed in the swing arm 32 in the horizontal direction, the positions of the locking holes 322 correspond to those of the adjustment holes 321, and the locking holes 322 are communicated with the adjustment holes 321; by using bolts to penetrate into the locking holes 322 and abut against the side wall of the fixed shaft 31, the position of the fixed shaft 31 in the adjustment hole 321 is fixed.

[0044] Refer to Figure 1 , the placing cylinder 6 has an upward opening, and the shape inside the placing cylinder 6 corresponds to that of the rotating bowl 9, so that the rotating bowl 9 can be stably placed in the placing cylinder 6.

[0045] In other embodiments, a plurality of placing cylinders 6 can be placed on the support platform 5, and the placing cylinders 6 have different sizes and can be flexibly selected according to actual needs.

[0046] The implementation principle of a rotating bowl cleaning device disclosed in an embodiment of the present application is as follows: when the countercurrent centrifuge is used up, the centrifugally recovered substances will adhere to the inner wall of the rotating bowl 9, and it is necessary to wash off the substances adhering to the inner wall of the rotating bowl 9. The rotating bowl 9 is taken out from the countercurrent centrifuge, cleaning liquid or solution is added to the rotating bowl 9, and then the rotating bowl 9 is placed in the placing cylinder 6. The driving motor 2 drives the transmission mechanism 3 to rotate, and with the supporting effect of the auxiliary shaft 4, the support platform 5 swings in the horizontal direction; the swing of the support platform 5 drives the swing of the rotating bowl 9, so that the cleaning liquid or solution in the rotating bowl 9 rotates in the rotating bowl 9, and then the substances adhering to the inner wall of the rotating bowl 9 are washed off by the cleaning liquid or solution and finally mixed into the cleaning liquid or solution to achieve the cleaning of the inner wall of the rotating bowl 9.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
