Description

Technical Field

[0001] The utility model relates to the technical field of microsphere separation, in particular to a water changing device used for microsphere sedimentation. Background Art

[0002] Microspheres are small particles of different sizes generated by a chemical synthesis process. Generally, a microsphere suspension is first obtained by mixing microspheres, distilled water and an organic solvent. The microspheres are then separated from the microsphere suspension by natural sedimentation. As a result, operators need to wait for a long time for the microspheres to settle in order to obtain a microsphere product containing distilled water, and the operation efficiency is low.

[0003] In addition, currently the microsphere suspension needs to be separated multiple times to obtain the microsphere product, and after each microsphere sedimentation, the microsphere solution formed after the microsphere sedimentation needs to be added with distilled water, and then the microsphere sedimentation is performed again to obtain a microsphere product with a lower content of impurities such as organic solvents. Finally, after so many repeated operations, a qualified microsphere product is obtained. Such operations bring great inconvenience to the operators, and each repeated operation may result in the loss of a part of the microspheres, which significantly reduces the final yield of the microspheres.

[0018] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1 and Figure 2As shown, the present embodiment provides a water-changing device for sedimentation of microspheres (hereinafter referred to as the water-changing device), and is used for sedimentation and separation of microspheres. The water-changing device includes a cylinder, in which an upper cavity 31 and a lower cavity 51 arranged in an upper and lower manner are arranged, and a separator 4 is located between the upper cavity 31 and the lower cavity 51. The outer wall of the cylinder is provided with an inlet 2 connected to the upper cavity 31 and an outlet 6 connected to the lower cavity 51. The separator 4 has a spiral pipeline 13 for sedimentation and separation of microspheres in a microsphere suspension. A microsphere inlet 11 and a microsphere outlet 12 are respectively provided at both ends of the spiral pipeline 13. The microsphere inlet 11 is connected to the inlet 2, and the microsphere outlet 12 is connected to the outlet 6, and the outlet 6 is equipped with a first valve 7.

[0021] In this embodiment, the feed inlet 2 is provided with a sealing cover 1, and the sealing cover 1 is detachably covered on the feed inlet 2, and the feed inlet 2 is closed and sealed by the sealing cover 1 to prevent the microspheres from being contaminated by the outside when settling.

[0022] In addition, the feed port 2 is located at the upper part of the cylinder, and the discharge port 6 is located at the lower part of the cylinder to ensure the height difference or potential energy difference so that the microspheres move downward into the cavity 51 under their own gravity.

[0023] When the microspheres need to be separated, the first valve 7 is first closed, and then the sealing cover 1 is opened. Then, the microsphere suspension containing microspheres, distilled water and organic solvent is poured into the upper cavity 31 through the feed inlet 2, and then the sealing cover 1 is covered to seal the feed inlet 2.

[0024] At the same time, the microsphere suspension that has flowed into the upper cavity 31 passes through the microsphere inlet 11 of the separator 4, and then rotates downward in a spiral manner along the spiral pipe 13 and forms a centrifugal force. At this time, the microspheres are thrown toward the inner wall of the separator 4 under the action of the centrifugal force, and sink toward the microsphere outlet 12 under the action of their own gravity, and then pass through the microsphere outlet 12 and settle in the lower cavity 51. Finally, after the microspheres have settled, the remaining solution containing impurities such as organic solvents remaining in the upper cavity 31 is poured out or replaced from the feed inlet 2.

[0025] After the remaining solution containing impurities such as organic solvents remaining in the upper cavity 31 is poured out, the first valve 7 is opened to discharge the microsphere product containing a small amount of distilled water from the discharge port 6 to obtain the microsphere product.

[0026] The spiral pipeline 13 of the separator 4 in the cylinder is used to quickly settle and separate the microspheres in the microsphere suspension, thereby reducing the time for operators to wait for the microspheres to settle and improving the efficiency of microsphere separation.

[0027] In another preferred embodiment, the cylinder includes an upper cylinder 3 and a lower cylinder 5, the upper cylinder 3 can be detachably assembled on the lower cylinder 5, the inner cavity of the upper cylinder 3 is the upper cavity 31, the inner cavity of the lower cylinder 5 is the lower cavity 51, and the separator 4 is arranged in the middle part of the cylinder. Through the detachable assembly relationship between the upper cylinder 3 and the lower cylinder 5, it is convenient for the operator to clean, wash and maintain the interior of the water changing device.

[0028] Further preferably, an upper return port 32 connected to the upper cavity 31 and a lower return port 52 connected to the lower cavity 51 are formed on the outer wall of the cylinder, the microball inlet 11 is connected to the upper return port 32, the microball outlet 12 is connected to the lower return port 52, a reflux pipeline 10 for reflux of the microballs is connected between the upper return port 32 and the lower return port 52, and the upper return port 32, the upper cavity 31, the separator 4, the lower return port 52 and the reflux pipeline 10 together constitute a complete reflux channel to cooperate with multiple microball sedimentation operations, thereby ensuring that impurities such as organic solvents are separated and removed from the microball product.

[0029] In this specific embodiment, the upper circuit port 32 is arranged on the circumferential wall of the upper cavity 31 and is equipped with a second valve 9, and is located below the feed port 2, and the lower circuit port 52 is arranged on the circumferential wall of the lower cavity 51 and is equipped with a third valve 8, and is close to the bottom of the lower cavity 51. In addition, the specific first valve 7, second valve 9 and third valve 8 are all knob switches.

[0030] When multiple microsphere sedimentation is not required, the second valve 9 and the third valve 8 are closed to close the reflux pipeline 10 so that it is closed and ineffective, and the microsphere product containing a small amount of distilled water separated once is discharged from the opened discharge port 6.

[0031] When multiple microsphere sedimentation is required, the discharge port 6 is closed. After each microsphere sedimentation is completed, the remaining solution containing impurities such as organic solvents remaining in the upper cavity 31 is poured out from the feed port 2, and then the second valve 9 and the third valve 8 are opened to start the reflux pipeline 10. Then, distilled water is added from the feed port 2, and the distilled water flows into the lower cavity 51 along the spiral pipeline 13 of the separator 4. The spiral pipeline 13 of the separator 4 is used to make the flow of the distilled water and other liquids passing therethrough The speed is reduced to realize the conversion of the kinetic energy of the liquid into pressure energy, thereby ensuring the power of the microsphere reflux, so that the microspheres located at the bottom of the lower cavity 51 are pressed into the reflux pipe 10 together with the distilled water, and reflux upward to the upper cavity 31 to realize water replacement, and then the microspheres are precipitated. This is repeated many times until the organic solvent and other impurities in the remaining solution in the upper cavity 31 are removed after the microspheres are precipitated, and then the second valve 9 and the third valve 8 are closed, and then the first valve 7 is opened to obtain a clean and qualified microsphere product.

[0032] Through the cooperation of the reflux pipeline 10, the water changing device of this embodiment can prevent the waste of microspheres caused by pouring out the microspheres and changing the water many times in the prior art, while saving time and labor, accelerating the sedimentation speed, and effectively improving the final yield of microspheres.

[0033] Of course, in other embodiments, the upper loop port 32 is equipped with a second valve 9, or the lower loop port 52 is equipped with a third valve 8, that is, the entire return line 10 only needs one valve to control the opening and closing, and the opening and closing of the return channel can also be effectively controlled.

[0034] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
