[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. It should also be noted that all directional indications in the embodiments of the utility model (such as up, down, left, right, front, back, inside, outside) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] See also Figure 1-Figure 3 The embodiment of the utility model provides a batch processing centrifuge, comprising a base 1, a turntable frame 2 and at least two shelves 3. A rotary driving member 4 is provided in the base 1. The output end of the rotary driving member 4 is connected to the middle of the turntable frame 2 to drive the turntable frame 2 to rotate around its own axis. The shelves 3 are distributed on the turntable frame 2 along the circumferential direction and are centrally symmetrical relative to the axis of the turntable frame 2. The shelves 3 and the turntable frame 2 are detachably connected; each shelf 3 is provided with a receiving portion 31 for fixing a sample box 5, and the sample box 5 is provided with a plurality of sample slots 51.

[0023] The above scheme provides a plurality of circumferentially distributed shelves 3 on the turntable frame 2, and a receiving portion 31 is provided on each shelf 3, so that the sample box 5 is effectively fixed by the receiving portion 31. Since each sample box 5 is provided with a plurality of sample slots 51, a plurality of samples or test tubes can be accommodated at one time, and subsequent batch centrifugation processing is realized, and the operation is more convenient. In addition, by designing the shelf 3 and the turntable frame 2 to be detachably connected, different types of sample boxes 5 can be adapted by replacing the shelf 3 with different receiving portions 31, thereby effectively improving the versatility.

[0024] The number of the shelves 3 is an even number, so that the center of gravity of the turntable frame 2 is more stable when rotating. In this embodiment, the number of the shelves 3 is four. As an optimization of the turntable frame 2, the turntable frame 2 is provided with the same number of receiving grooves 21 as the shelves 3. The receiving grooves 21 are distributed along the circumference of the turntable frame 2 and are centrally symmetrical relative to the axis of the turntable frame 2. The shelves 3 are correspondingly arranged in the receiving grooves 21 one by one, so that the shelves 3 can be more stable on the turntable frame 2 due to the limiting effect of the receiving grooves 21.

[0025] In this embodiment, the rotary drive member 4 is preferably a motor, and a shaft hole 25 for inserting the output shaft of the power supply motor is provided in the middle of the turntable frame 2.

[0026] In this embodiment, the outer edge of the turntable frame 2 is provided with an annular rib 23 arranged vertically, and the annular rib 23 extends to the top and bottom of the turntable frame 2 at the same time, and the side of the shelf 3 facing away from the axis of the turntable frame 2 is connected to the annular rib 23, thereby ensuring that when the turntable frame 2 rotates, the annular rib 23 can effectively support the shelf 3.

[0027] More specifically, in the present embodiment, the detachable connection between the shelf 3 and the turntable frame 2 means that: the inner side wall of the annular rib 23 is provided with a vertical mounting hole 24, the shelf 3 is provided with a vertical assembly hole 32, and the assembly hole 32 is provided with a bolt detachably connected to the mounting hole 24, thereby making the disassembly and assembly of the shelf 3 relative to the turntable frame 2 simple and convenient.

[0028] In this embodiment, the receiving portion 31 is a boss and is arranged on the side of the axis of the shelf 3 facing the turntable frame 2. The sample box 5 is provided with a slot 52 for being snapped into the boss. The slot of the sample slot 51 is located on the side of the axis of the sample box 5 facing the turntable frame 2. After adopting the above structure, the fixation of the sample box 5 relative to the receiving portion 31 is simple and convenient. Moreover, since the slot of the sample slot 51 is located on the side of the axis of the sample box 5 facing the turntable frame 2, the problem of the sample or test tube falling out of the sample slot 51 during the rotation of the turntable frame 2 can be avoided.

[0029] Furthermore, the multiple sample slots 51 on the sample box 5 are arranged in a grid shape, which is more neat and has a high space utilization rate, and can accommodate more samples or test tubes.

[0030] In some embodiments, the sample slot 51 is used for inserting a test tube containing a sample;

[0031] In other embodiments, the sample slot 51 is used to directly receive the sample, and the sample box 5 is provided with a sealing film for closing the notch of the sample slot 51, so that the usage of the sample box 5 can be freely selected according to actual needs.

[0032] As an improvement to the above embodiment, at least two weight-reducing holes 22 distributed along the circumferential direction are provided on the turntable frame 2. All weight-reducing holes 22 are centrally symmetrical with respect to the axis of the turntable frame 2. The setting of the weight-reducing holes 22 can effectively reduce the weight of the turntable frame 2.
