[0020] like Figs. 1-3 As shown, a compact continuous separation centrifuge with dual-speed output includes a motor 1, a coupling 2, a rotating drum 3, a lower gear 4, a base 5, a lower bearing 6, a side gear 7, a side bearing 8, a horizontal axis 9, a vertical axis 10, a side gear cover 11, an upper bearing 12, an upper gear 13, a high-speed turntable 14, a pipe clamp 15, a pipe support 16, a protective cover 17, and a counterweight 18.
[0021] The output end of motor 1 is connected to drum 3 through coupling 2, which drives drum 3 to rotate synchronously.
[0022] Rotating drum 3 is an asymmetrical structural component.
[0023] The lower gear 4 is a bevel gear with a number of teeth, and it is fixed on the base 5 and remains stationary. A lower bearing 6 is installed between the lower gear 4 and the rotating drum 3 to ensure the smooth rotation of the rotating drum 3.
[0024] The side gear 7 is a bevel gear with b teeth, fixed on the rotating drum 3, and meshes with the teeth of the lower gear 4 and the upper gear 13 respectively; there can be one or more side gears 7; a side gear cover 11 is installed on the side gear 7; a side bearing 8 is installed between the side gear 7 and the rotating drum 3; the side gear 7 can rotate around the horizontal axis 9, and can also rotate synchronously with the motor 1 around the vertical axis 10 under the drive of the rotating drum 3.
[0025] The upper gear 13 is a bevel gear with the same number of teeth a as the lower gear 4; an upper bearing 12 is installed between the upper gear 13 and the rotating drum 3 to ensure that the upper gear 13 can rotate smoothly around the vertical axis 10; the rotation direction of the upper gear 13 is the same as that of the rotating drum 3.
[0026] The high-speed turntable 14 is fastened to the upper gear 13 and is used to mount the mixed liquid load 19. It rotates synchronously with the upper gear 13. The pipe clamp 15 is fixed on the high-speed turntable 14 and is used to mount the interface of the mixed liquid load connecting pipe 20.
[0027] 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.
[0028] The counterweight 18 is fixed on the rotating drum 3 and is opposite to the installation position of the side gear 7, so as to prevent the asymmetric rotating drum 3 from being deflected when rotating.
[0029] The lower gear 4 and the side gear 7 constitute a bevel gear meshing transmission structure, and the transmission ratio formed is the tooth number ratio of the lower gear 4 and the side gear 7, that is, a / b; the side gear 7 and the upper gear 13 constitute a bevel gear meshing transmission structure, and the transmission ratio formed is the tooth number ratio of the side gear 7 and the upper gear 13, that is, b / a.
[0030] The working principle of the application is as follows:
[0031] 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 directly connected with the rotating drum 3 and the protective cover 17 rotate around the vertical axis 10 at the same time, and the speed is also V1, so as to realize the output of low rotating speed V1.
[0032] 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 and the side gear 7 directly connected with the rotating drum 3 rotate around the vertical axis 10 at the same time, and the speed is also V1. At the same time, the side gear 7 and the lower gear 4 are in the bevel gear meshing transmission structure, the lower gear 4 is fixed, and the side gear 7 rotates around the horizontal axis 9 at the speed V'. Thus, it can be known that 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 V2 of the upper gear 13 in one direction around the vertical axis 10, V2 is consistent with the rotating direction of V1, V2 is greater than V1, and the ratio of V2 to 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, so as to realize the output of high rotating speed V2.
[0033] Based on the above, the compact continuous separation centrifuge for realizing double-speed output, under the premise of only one motor, through the engagement transmission structure of two pairs of bevel gears, the rotary centrifugal speed V1 is outputted at the pipeline support 16 and the protective cover 17, and the rotary centrifugal speed V2 is outputted at 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.
[0034] The above is only for illustrating the technical idea of the present application, and cannot limit the protection scope of the present application, any modification made according to the technical idea of the present application on the basis of the technical scheme falls into the protection scope of the claims of the present application.
