Description
TECHNICAL FIELD
[0001] The utility model relates to centrifugal separation field especially relates to a compact continuous separation centrifuge realizing double speed output. BACKGROUND
[0002] In blood component separation and biological experiments, high-efficiency and continuous centrifugal separation of mixed liquid containing multiple component particles is a key technical requirement. Traditional centrifugal separation technology usually relies on a single-speed centrifugal environment, and uses the sedimentation coefficient difference of each component particle in the mixed liquid due to the density difference to make different components sequentially settle and separate under a specific centrifugal field. However, in many practical application scenarios, the mixed liquid to be separated often needs to be connected to an external liquid supply or collection system through a pipeline. When the centrifugal system rotates at high speed, if the connecting pipeline rotates at high speed synchronously with the centrifugal part, it is easy to cause the pipeline to wind, twist or even damage, which seriously restricts the continuity and stability of the centrifugal separation process; if the pipeline is fixed, the centrifugal part rotating at high speed and the stationary pipeline will produce violent relative motion and friction, which may not only affect the separation effect, but also may contaminate or damage the sample, and also increases the complexity and safety hazards of the equipment structure design. Therefore, how to effectively solve the motion interference and pipeline winding problem between the high-speed rotating centrifugal part and the external connecting pipeline while ensuring the centrifugal separation effect, and realize the continuous and stable supply of mixed liquid and the efficient collection of separation products, has become an important bottleneck restricting the development of traditional centrifugal separation technology to a higher level of automation and continuity.

[0013] Rotary drum 3 is asymmetric structure.
[0014] Lower gear 4 is bevel gear, and the number of teeth is a, is fixed on base 5, is stationary;Lower gear 4 and rotary drum 3 are equipped with lower bearing 6 between, guarantee the smooth rotation of rotary drum 3.
[0015] Side gear 7 is bevel gear, and the number of teeth is b, is fixed on rotary drum 3, is engaged with the gear teeth of lower gear 4 and upper gear 13 respectively;Side gear 7 can be one or more than one;Side gear 7 is equipped with side gear cover 11 on;Side gear 7 and rotary drum 3 are equipped with side bearing 8 between;Side gear 7 can rotate around horizontal axis 9, and can be driven by rotary drum 3 and rotate around vertical axis 10 with motor 1 synchronous rotation.
[0016] The upper gear 13 is a bevel gear with the same number of teeth a as the lower gear 4; the upper gear 13 and the rotating drum 3 are connected by the upper bearing 12 to ensure smooth rotation of the upper gear 13 around the vertical axis 10; the rotation direction of the upper gear 13 is the same as that of the rotating drum 3.
[0017] The high-speed rotating disc 14 is fixed on the upper gear 13 and used for clamping the mixed liquid load 19 and rotating synchronously with the upper gear 13; the pipe clamp 15 is fixed on the high-speed rotating disc 14 and used for clamping the interface of the mixed liquid load connecting pipeline 20.
[0018] The pipeline support 16 and the protective cover 17 are fixed on the rotating drum 3 and rotate synchronously with the rotating drum 3; the pipeline support 16 is used for fixing the mixed liquid load connecting pipeline 20 and driving the mixed liquid load connecting pipeline 20 to rotate synchronously.
[0019] The counterweight 18 is fixed on the rotating drum 3 and opposite to the installation position of the side gear 7 to prevent the asymmetric rotating drum 3 from swinging when rotating.
[0020] The lower gear 4 and the side gear 7 form a bevel gear meshing transmission structure, and the transmission ratio is the ratio of the number of teeth of the lower gear 4 and the side gear 7, that is, a / b; the side gear 7 and the upper gear 13 form a bevel gear meshing transmission structure, and the transmission ratio is the ratio of the number of teeth of the side gear 7 and the upper gear 13, that is, b / a
[0021] The working principle of the utility model is as follows:
[0022] The output principle of low rotating speed: when the motor 1 rotates at the speed V1, the rotating drum 3 directly connected with the motor 1, the pipeline support 16 and the protective cover 17 directly connected with the rotating drum 3 rotate around the vertical axis 10 at the same speed V1, thereby realizing the output of low rotating speed V1.
[0023] The output principle of high rotating speed: when the motor 1 rotates at the speed V1, the rotating drum 3 directly connected with the motor 1, the side gear 7 directly connected with the rotating drum 3 rotates around the vertical axis 10 at the speed V1. At the same time, the side gear 7 and the lower gear 4 are in the formed bevel gear meshing transmission structure, the lower gear 4 is fixed, the side gear 7 rotates around the horizontal axis 9 at the speed V'. Thus, the side gear 7 rotates in two perpendicular directions: the rotating speed V1 around the vertical axis 10 and the rotating speed V' around the horizontal axis 9. At the same time, the side gear 7 and the upper gear 13 are in the bevel gear meshing transmission relationship, the rotation of the side gear 7 in two perpendicular directions is changed into the rotation of the upper gear 13 in one direction around the vertical axis 10 V2, V2 is consistent with the rotating direction of V1, V2 is greater than V1, and the ratio of V2 and V1 is fixed. Under the driving of the upper gear 13, the high-speed rotating disc 14 directly connected with the upper gear 13 also rotates around the vertical axis 10 at the speed V2, thus the output of high rotating speed V2 is realized.
[0024] Based on the above, the compact continuous separation centrifuge for realizing double-speed output under the premise of only one motor, through two pairs of bevel gear meshing transmission structures, simultaneously outputs the rotating centrifugal speed V1 through the pipeline support 16 and the protective cover 17, and outputs the rotating centrifugal speed V2 through the high-speed rotating disc 14, the two speeds V1 and V2 are in the same direction, different in size and fixed in proportion, the mixed liquid load 19 containing multiple component particles is placed on the high-speed rotating disc 14 and rotates at the high speed V2, the mixed liquid load connecting pipeline 20 is placed on the pipeline support 16 and rotates at the low speed V1, the high speed V2 and the low speed V1 keep a fixed proportion, which not only prevents the mixed liquid load connecting pipeline 20 from winding in rotation, but also realizes the continuous separation of the mixed liquid containing multiple component particles.
