[0023] Example 1

[0024] See also Figure 1-3 As shown, a device for centrifugal mother liquor stratification processing includes a shell 1, and a cover 15 is provided on the shell 1. When not in use or during centrifugal operation, the cover 15 covers the opening. A motor 2 is fixedly provided in the shell 1, and a centrifugal mechanism 3 for centrifugal separation is fixedly provided on the output shaft of the motor 2. The centrifugal mechanism 3 includes a placement plate 4 and a clamping assembly 5 for clamping a test tube. The placement plate 4 is coaxially fixedly installed on the output shaft of the motor 2. A plurality of clamping assemblies 5 are provided, and four clamping assemblies 5 are provided. Four clamping assemblies 5 are arranged in a circular array on the placement plate 4.

[0025] A driving assembly 6 for controlling the clamping assembly 5 to clamp the test tube is provided on the placement plate 4. The driving assembly 6 is coaxially fixed on the placement plate 4. The driving assembly 6 includes a motor 2 61 and a rotating disk 62 for controlling the clamping of the clamping assembly 5. Two rotating disks 62 are provided. The rotating disk 62 is composed of two semi-circular disks, and the output shaft of the motor 2 61 is fixed at the midpoint of the two semi-circular disks, and the rotation range of the rotating disk 62 is less than 90 degrees. The motor 2 61 is coaxially fixed on the side of the placement plate 4 away from the motor 1 2, and the rotating disk 62 is coaxially fixed on the output shaft of the motor 2 61.

[0026] The clamping assembly 5 includes a support rod 51, a clamping ring 1 52 and a clamping ring 2 53. Rubber pads are fixedly installed on the clamping ring 1 52 and the clamping ring 2 53 to increase the friction between the test tube and the clamping ring 1 52 and the clamping ring 2 53. The support rod 51 is fixedly set on the placement plate 4, the clamping ring 1 52 is fixedly set on the side of the support rod 51 away from the placement plate 4, the clamping ring 2 53 is slidably set on the placement plate 4, the rotating plate 62 abuts against the clamping ring 2 53, and the clamping ring 2 53 cooperates with the clamping ring 1 52.

[0027] A slide bar 7 is fixedly provided at one end of the clamping ring 2 53 away from the clamping ring 1 52 , a slide groove 8 is provided on the placement plate 4 , the slide bar 7 is slidably provided in the slide groove 8 , and the rotating plate 62 abuts against the slide bar 7 .

[0028] A spring 9 is fixedly arranged on the side of the slide groove 8 away from the clamping ring 2 53. The spring 9 is used to reset the slide rod 7. When the slide rod 7 approaches the support rod 51, the spring 9 extends. Otherwise, the spring 9 returns to its initial state or contracts. The spring 9 is fixedly connected to the slide rod 7.

[0029] Example 2

[0030] See also Figure 1-3 As shown, a mounting plate 10 is fixedly provided on the support rod 51, a rotating rod 11 is rotatably provided on the mounting plate 10, a handle 16 is provided on the rotating rod 11, a screw rod 12 is coaxially fixedly provided on the rotating rod 11, a supporting plate 13 is threadedly connected to the screw rod 12, and the supporting plate 13 is slidably provided on the support rod 51. When adjusting the position of the supporting plate 13, the handle 16 is rotated to rotate the screw rod 12, and the supporting plate 13 threadedly connected to the screw rod 12 slides relative to the support rod 51. The supporting plate 13 can provide a supporting force for the test tube to prevent the test tube from sliding relative to the support ring 1 and the support ring 2 during the centrifugal operation, resulting in incomplete centrifugal stratification effect and unsatisfactory centrifugal result.

[0031] A fixing ring 14 is rotatably provided on the mounting plate 10 . The fixing ring 14 is coaxially fixedly provided on an end of the rotating rod 11 away from the screw rod 12 . The fixing ring 14 fixes the rotating rod 11 to prevent the rotating rod 11 from sliding relative to the mounting plate 10 when rotating.

[0032] When the utility model is in use, a test tube containing liquid to be centrifuged is placed between the clamping ring 1 52 and the clamping ring 2 53, and the motor 2 61 is started. The motor 2 61 controls the rotating disk 62 to rotate, so that the slide bar 7 abutting against the rotating disk 62 slides, and the clamping ring 2 53 fixedly connected to the slide bar 7 slides close to the clamping ring 1 52 until the test tube between the clamping ring 1 52 and the clamping ring 2 53 is clamped. At this time, the test tube identical to the first test tube is placed in the other three clamping assemblies 5. At this time, it is not necessary to adjust the positions of the clamping ring 1 52 and the clamping ring 2 53 to ensure that the test tube is clamped. When in use, multiple identical test tubes can be quickly clamped at the same time, making the centrifugation process smoother, ensuring stratification after centrifugation, and simple to operate.

[0033] After clamping a test tube, the handle 16 is turned to rotate the screw rod 12 fixedly connected to the handle 16, and the supporting plate 13 threadedly connected to the screw rod 12 slides up until the bottom of the test tube is supported. At this time, the other supporting plates 13 are also adjusted to the same position and the test tubes are placed in them. A supporting force is applied to the test tubes when they are centrifuged to prevent the test tubes from sliding in the clamping rings 1 52 and 2 53 during centrifugation, resulting in poor centrifugation results. After the test tubes are placed, the cover 15 is closed to carry out centrifugation.
