Description

Technical Field

[0001] The utility model relates to the technical field of material dispersion and mixing, in particular to an oscillating centrifugal integrated machine. Background Art

[0002] Material oscillation is a common method for mixing and dispersing materials. Mechanical vibrations are generated by a vibration source, causing liquids or solids to vibrate with small amplitudes and frequencies, thereby mixing the materials. Alternatively, the vibrations generated by the vibration source can cause the solids to vibrate violently. This leads to violent collisions between solid particles, thereby crushing them. Centrifugation, on the other hand, separates liquids and solid particles of varying densities, or liquid-liquid mixtures, by rotating the material at high speeds and utilizing the centrifugal force of the centrifuge. Oscillation and centrifugation are typically performed using a dispersing oscillator and a centrifuge, respectively. The material to be processed, such as test reagents, is placed on a dispersing oscillator for thorough mixing. After the reaction is complete, it is separated in a centrifuge to obtain the desired sample.

[0003] At present, there are also oscillating centrifugal machines on the market, which can complete the oscillation and centrifugation of materials in one machine. It is equipped with a rotating disk, an oscillating rod, an oscillating disk, a serrated disk and a lifting mechanism. The rotating disk drives the material to be centrifuged. When the material needs to be oscillated, the vibrating rod on the rotating disk rotates and rises and falls along the saw teeth on the serrated disk, thereby driving the oscillating disk to rise and fall, so as to complete the oscillation of the material on the oscillating disk.

[0036] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0037] like Figures 1 to 5 As shown, an embodiment of the present invention provides an oscillating centrifugal integrated machine, including a centrifugal mechanism 100 and an oscillating mechanism 200. The centrifugal mechanism 100 includes an oscillating centrifugal disk 110 and a rotating assembly 120. The oscillating centrifugal disk 110 is used to carry materials. The rotating assembly 120 is provided with a rotating rod 121 extending in a vertical direction. The oscillating centrifugal disk 110 is connected to the rotating rod 121. The rotating shaft can move around its own axis to drive the oscillating centrifugal disk 110 to rotate. The oscillating mechanism 200 includes an oscillating slider 210, an adapter 220 and a lifting drive assembly 230 slidably arranged on the transmission rod. The oscillating slider 210 can abut against the oscillating centrifugal disk 110. The adapter 220 is rotatably sleeved on the oscillating slider 210. The lifting drive assembly 230 can drive the adapter 220 to move in the vertical direction to drive the oscillating slider 210 and the oscillating centrifugal disk 110 to oscillate vertically.

[0038] That is, the oscillating centrifugal integrated machine provided by the present invention drives the oscillating centrifugal disk 110 to rotate by setting a rotating rod 121 to realize the centrifugation of the material. At the same time, an oscillating slider 210 is set on the rotating rod 121, and the oscillating slider 210 is driven by the lifting drive component 230 to push the oscillating centrifugal disk 110 to oscillate up and down, which solves the technical problems of the existing oscillating centrifugal integrated machine in the prior art that the oscillating rod is used to vibrate on the serrated disk to complete the material oscillation, resulting in high noise and short service life. It reduces noise, extends the service life of the oscillating centrifugal integrated machine, and meets actual production needs.

[0039] Specifically, the oscillating centrifugal machine is cylindrical as a whole, and the oscillating centrifugal disc 110 is circular and arranged in the horizontal direction. The rotating rod 121 is arranged in the vertical direction, and the horizontal cross-section of the rotating rod 121 is spline-shaped, and the center of the corresponding oscillating centrifugal disc 110 is provided with a spline-shaped through hole, so that the through hole can pass through during rotation. At this time, the rotation of the rotating rod 121 will drive the rotation of the oscillating centrifugal disc 110, and the oscillating centrifugal disc 110 can move up and down along the axial direction of the rotating rod 121. The oscillating slider 210 is slidably arranged on the rotating rod 121, and the oscillating slider 210 can abut against the oscillating centrifugal disc 110, thereby promoting the lifting and lowering of the oscillating centrifugal disc 110. The lifting drive assembly 230 can drive the adapter 220 to move in the vertical direction to drive the oscillating slider 210 and the oscillating centrifugal disc 110 to oscillate vertically, thereby completing the oscillation of the material.

[0040] Furthermore, the oscillating centrifugal integrated machine is also provided with a cylinder 300, a receiving cavity is provided in the cylinder 300, the centrifugal mechanism 100 and the oscillating mechanism 200 are both provided with receiving cavities, the oscillating centrifugal disc 110 is arranged in the receiving cavity along the horizontal direction, and is surrounded by the cylinder 300 to form a working cavity.

A receiving cavity is provided within the barrel 300, and both the centrifugal mechanism 100 and the oscillating mechanism 200 are provided with receiving cavities. The oscillating centrifugal disc 110 is horizontally positioned within the receiving cavity, with the outer wall of the oscillating centrifugal disc 110 adjacent to the inner wall of the barrel 300. This creates a separate working chamber within the barrel 300. This further separates the drive motor and other drive transmission components within the centrifugal mechanism 100 and the oscillating mechanism 200 from the material, reducing the risk of motor short circuits and material contamination.

[0042] Preferably, the oscillation mechanism 200 further includes a rotating bearing 240 . The rotating bearing 240 is disposed between the adapter 220 and the oscillation slider 210 . The adapter 220 is disposed in the horizontal direction.

Therefore, by providing the rotating bearing 240 between the adapter 220 and the oscillating slider 210, the adapter 220 can rotate horizontally around the oscillating slider 210, thereby preventing the rotation and lifting of the oscillating centrifugal disk 110 from interfering with each other, thereby enabling the oscillating centrifugal integrated machine to perform centrifugation and oscillation simultaneously or separately.

[0044] Furthermore, the rotating assembly 120 includes a fixed bracket 122 and a first driving motor 123 . The first driving member is vertically arranged on the fixed bracket 122 .

[0046] Furthermore, the lifting drive assembly 230 includes a second drive motor 231 and a transmission rod group 232, and the transmission rod group 232 is respectively connected to the second drive motor 231 and the adapter 220, so that the second drive motor 231 can drive the adapter 220 to move in the vertical direction.

[0047] Specifically, the second drive motor 231 is fixed at the bottom of the bracket 122 by bolt specifications, and the transmission rod group 232 can be set as a planar screw mechanism, whose two ends are respectively connected to the second drive motor 231 and the adapter 220, so that the second drive motor 231 can drive the adapter 220 to move in the vertical direction.

[0049] Specifically, the second drive motor 231 is a double-ended reduction motor with two opposing output shafts. Two transmission rod assemblies 232 are located on either side of the second drive motor 231 and connected to its output shafts. The other ends of the two transmission rod assemblies 232 are connected to the ends of the adapter 220, ensuring stable lifting and lowering of the adapter 220.

[0050] Preferably, the transmission rod group 232 includes a crank 2321, a connecting rod 2322 and a rocker 2323, one end of the crank 2321 is connected to the second drive motor 231, the two ends of the connecting rod 2322 are respectively hinged to the other end of the crank 2321 and one end of the rocker 2323, and the other end of the rocker 2323 is fixed to the adapter 220.

[0051] Specifically, the crank 2321, connecting rod 2322, and rocker 2323 cooperate to form the crank 2321 / rocker 2323 mechanism.

The other end of the rocker 2323 is cylindrical, with mounting holes provided at both ends of the adapter 220. The other end of the rocker 2323 can be inserted into the mounting holes and connected to the adapter 220 via bolts or welding, thereby driving the adapter 220 to rise and fall.

[0052] Furthermore, a plurality of reaction tubes 111 are evenly arranged on the oscillating centrifugal disc 110, and the reaction tubes 111 are used to carry materials. The oscillating centrifugal machine also includes a liquid injection mechanism 400, which includes a liquid injection disc 410, a liquid injection needle 420, and a second lifting assembly 430.

[0053] Specifically, in this embodiment, eight reaction tubes 111 are arranged in a circular array on the oscillating centrifugal disk 110.
