[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 and Figure 2As shown, a probiotic freeze-dried powder nano-microsphere screening device includes a shell 1, a base 2 is fixedly connected to the lower part of the outer surface of the shell 1, a motor 3 is fixedly connected to the middle part of the upper end of the shell 1, a feed port 11 is symmetrically opened at the upper end of the shell 1, an inverted conical feed cylinder 4 is fixedly connected to the upper part of the inner surface of the shell 1, an inverted frustum-shaped sieve cylinder 5 is fixedly connected to the bottom of the inverted conical feed cylinder 4, an aggregate structure 1 6 is fixedly connected to the middle and lower part of the inner surface of the shell 1, and an aggregate structure 2 7 is fixedly connected to the lower part of the inner surface of the shell 1. The outer surface of the output end of the motor 3 passes through the upper end of the shell 1 and extends to the inner surface of the shell 1. The bottom end of the output end of the motor 3 is fixedly connected to a rotating shaft 31, the bottom of the rotating shaft 31 is fixedly connected to a stirring structure 8, and a supporting structure 9 is provided at the bottom of the rotating shaft 31.

[0025] When the device in this scheme starts to run, the user fixes the entire device through the fixed base 2, and then the user slowly and continuously adds the probiotic freeze-dried powder to be screened into the inner cavity of the inverted conical feed cylinder 4 and the inverted frustum-shaped screen cylinder 5 through the feed port 11. At the same time, the inverted conical feed cylinder 4 and the inverted frustum-shaped screen cylinder 5 cooperate to prevent the probiotic freeze-dried powder from splashing out during the screening process. At the same time, the longer inverted frustum-shaped screen cylinder 5 allows the probiotic freeze-dried powder to be fully stirred and screened. Secondly, the normal operation of the motor 3 drives the stirring structure 8 and the support structure 9 to rotate, and at the same time, the probiotic freeze-dried powder nanoparticles are screened with filter holes of different pore sizes, thereby screening out microsphere particles that meet the requirements.

[0026] See Figure 3 The aggregate structure 6 includes an aggregate bin 61 whose outer surface is fixedly connected to the middle and lower part of the inner surface of the shell 1, a filter hole 63 is opened at the top of the aggregate bin 61, the top of the aggregate bin 61 is fixedly connected to the bottom of the inverted frustum-shaped screen drum 5, and a discharge port 1 is opened in the middle of the bottom end of the aggregate bin 61, and a sealing cover 62 is slidably connected to the inner cavity of the discharge port.

[0027] In this solution, the inner diameter of the filter hole 63 is relatively large, and all the probiotic freeze-dried powder nanoparticles to be screened can pass through.

[0028] When the device in this scheme is running, the microsphere particles of the probiotic freeze-dried powder are filtered and screened with different pore sizes, and the probiotic freeze-dried powder nano-microspheres that do not meet the requirements pass through the filter hole 63 and fall into the inner cavity of the collection bin 61. After the overall screening is completed, the user removes the sealing cover 62 and collects the nano-microsphere particles that do not meet the requirements through the discharge port 1 for subsequent operations.

[0029] See Figure 3 、 Figure 4 and Figure 5 The stirring structure 8 includes a stirring drum 82 fixedly connected to the bottom end of the rotating shaft 31. The stirring drum 82 is located in the inner cavity of the inverted frustum-shaped screen drum 5 and is rotatably connected to the lower part of the outer surface of the stirring drum 82 and the middle part of the bottom wall of the inner surface of the inverted frustum-shaped screen drum 5.

[0030] When the motor 3 in this solution is working normally, the rotating shaft 31 is driven to rotate, thereby rotating the stirring drum 82, driving the spiral stirring blades 81 and the plurality of stirring rollers 84 to rotate, thereby stirring the probiotic freeze-dried powder nanoparticles located in the inner cavity of the inverted frustum-shaped sieve drum 5.

[0031] See Figure 3 A plurality of filter holes 83 are provided in a circular array on the outer surface of the mixing drum 82. A spiral stirring blade 81 is fixedly connected to the upper part of the outer surface of the mixing drum 82 and located in the upper middle part of the inner cavity of the inverted frustum-shaped sieve drum 5. A plurality of filter holes 811 are provided on the outer surface of the spiral stirring blade 81.

[0032] See Figure 5 There are several stirring rollers 84 in a circular array in the middle and lower part of the outer surface of the mixing drum 82 and located in the middle and lower part of the inner cavity of the inverted frustum-shaped sieve drum 5. The lower part of the outer surface of the mixing drum 82 is slidingly connected to the middle part of the outer surface of the sealing cover 62, and the middle and lower part of the outer surface of the mixing drum 82 is fixedly connected to the middle part of the top of the collecting bin 61.

[0033] In this embodiment, the pore size of the filter hole 83 is set to allow the probiotic freeze-dried powder nanoparticles that meet the requirements to pass through, while the nanoparticles with a larger inner diameter cannot pass through.

[0034] When the probiotic freeze-dried powder nano-microspheres enter the inner cavity of the inverted conical feed barrel 4 through the feed port 11, the rotating shaft 31 rotates at this time, driving the spiral stirring blade 81 and the stirring roller 84 to rotate. When the probiotic freeze-dried powder nano-microspheres automatically move downward from the inner cavity of the inverted conical feed barrel 4, they first contact the spiral stirring blade 81, and the spiral stirring blade 81 stirs the probiotic freeze-dried powder. At the same time, the filter hole three 811 cooperates to disperse the probiotic freeze-dried powder nano-microspheres. At the same time, the dispersed probiotic freeze-dried powder nano-microspheres that meet the requirements enter the inner cavity of the mixing barrel 82 through the filter hole four 83 and automatically move downward. At the same time, some microsphere particles with a diameter smaller than the requirement will enter the inner cavity of the mixing barrel 82.

[0035] Similarly, the probiotic freeze-dried powder nanoparticles to be screened continue to move downward, passing through a plurality of stirring rollers 84 and filter holes 83 to continue screening the microparticles that meet the requirements into the inner cavity of the mixing drum 82.

[0036] At the same time, the probiotic freeze-dried powder nanoparticles with a diameter larger than the required diameter fall into the inner cavity of the collection bin 61 and wait for final collection and processing.

[0037] See Figure 5 The aggregate structure 7 includes an aggregate bin 71 whose outer surface is fixedly connected to the lower part of the inner surface of the outer shell 1. The top of the aggregate bin 71 is slidably connected to the inner surface of the mixing drum 82. A filter hole 72 is provided at the top of the aggregate bin 71. A discharge port 2 is provided in the middle of the bottom end of the aggregate bin 71. A sealing ring 73 is slidably connected to the inner cavity of the discharge port 2.

[0038] In this solution, the aperture of the second filter hole 72 is set to be slightly smaller than the required diameter.

[0039] When the probiotic freeze-dried powder nano-microspheres that meet the requirements and have a diameter smaller than the required diameter enter the inner cavity of the mixing drum 82 and move downward, the probiotic freeze-dried powder nano-microspheres that do not meet the requirements fall into the inner cavity of the collection bin 2 71 through the second filter hole 72. After the final screening is completed, the sealing ring 73 is removed to collect the probiotic freeze-dried powder nano-microspheres that do not meet the requirements.

[0040] At the same time, the probiotic freeze-dried powder nano-microspheres that meet the requirements remain in the sealed cavity formed by the top of the second collecting bin 71 and the lower part of the inner surface of the mixing drum 82. After the screening is completed, the second collecting bin 71 is removed and the probiotic freeze-dried powder nano-microspheres that meet the requirements are collected.

[0041] See Figure 4 and Figure 5 The supporting structure 9 includes a supporting circular plate 91 fixedly connected to the bottom end of the rotating shaft 31, the outer surface of the supporting circular plate 91 is fixedly connected to the inner surface of the mixing drum 82, and a supporting rod 92 is fixedly connected to the middle of the lower end of the supporting circular plate 91. The lower part of the outer surface of the support rod 92 is slidingly connected to the middle part of the outer surface of the sealing ring 73, and the lower and middle part of the outer surface of the support rod 92 is fixedly connected to the middle of the top of the aggregate bin 71.

[0042] When the rotating shaft 31 rotates, the supporting circular plate 91 is driven to rotate simultaneously, and the supporting rod 92 and the second collecting bin 71 are rotated at the same time, so that the whole structure rotates simultaneously, which is convenient for screening the probiotic freeze-dried powder nanoparticles.

[0043] It should be noted that the specific installation method of the motor 3, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0044] The working principle of this utility model is:

[0045] The user first activates the motor 3 to make it work normally, then cooperates with the sealing ring 73 to form the discharge port 2 and the sealing cover 62 to form the discharge port 1 to seal the bottom of the entire device, and then slowly pours the freeze-dried probiotic powder nanoparticles to be screened into the inner cavity of the inverted conical feed barrel 4 through the feed port 11.

[0046] When motor 3 is operating normally, its output end rotates, driving shaft 31 to rotate, thereby rotating mixing drum 82. At this time, spiral stirring blades 81 and a plurality of stirring rollers 84 rotate, stirring and screening the probiotic freeze-dried powder nanoparticles that fall from the inner cavity of inverted conical feed drum 4 into the inner cavity of inverted truncated cone sieve drum 5. Probiotic freeze-dried powder nanoparticles that meet the requirements or have a diameter smaller than the required diameter pass through filter holes 9 83 and enter the inner cavity of mixing drum 82. Meanwhile, probiotic freeze-dried powder nanoparticles with a diameter larger than the required diameter flow along the inner surface of inverted truncated cone sieve drum 5 and the outer surface of mixing drum 82, through filter holes 1 63, and fall into the inner cavity of collection bin 1 61.

[0047] At the same time, the probiotic freeze-dried powder nanospheres in the inner cavity of the mixing drum 82 pass through the filter hole 2 72, and the probiotic freeze-dried powder that does not meet the requirements falls into the inner cavity of the collecting bin 2 71, among which the probiotic freeze-dried powder that meets the requirements is sealed in the sealed cavity formed by the top of the collecting bin 2 71 and the lower part of the inner surface of the mixing drum 82.

[0048] Finally, after all the screening is completed, the user collects the unqualified probiotic freeze-dried powder nano-microspheres in the inner cavity of the collection bin 1 61 and the inner cavity of the collection bin 2 71 for subsequent processing, and collects the qualified probiotic freeze-dried powder nano-microspheres in the inner cavity of the mixing drum 82 for the next step.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
