[0036] Microdroplets refer to small liquid droplets with small volume and liquid state, which have wide application potential in many fields. When microdroplets are produced, they often flow into the container for collecting microdroplets together with the excess continuous phase liquid. In order to obtain individual microdroplets, the mixed continuous phase liquid and microdroplets need to be separated. However, the current collection container cannot meet this requirement, and therefore a collection device capable of separating the mixed continuous phase liquid and microdroplets is needed.
[0037] Based on the above problems, the baffle is arranged in the embodiments of the present disclosure to separate the first channel through which the microdroplets enter the collection cavity and the liquid inlet of the medium discharge pipe, so as to avoid the situation that the microdroplets entering the collection cavity enter the liquid inlet and are mistakenly discharged from the collection cavity, thereby indirectly improving the yield of microdroplets by avoiding the waste of microdroplets.
[0038] Figure 1 Fig. 1 shows a cross-sectional schematic view of the overall structure of the microdroplet collection device in the embodiments of the present disclosure. Figure 2 Fig. 2 shows a cross-sectional schematic view of the microdroplet collection device from another perspective in the embodiments of the present disclosure. Figure 1 and Figure 2 In an example, the microdroplet collection device includes a collection container 10, a baffle 20 and a medium discharge pipe 30. The collection container 10 includes a collection cavity 101 having a top opening 102. The baffle 20 is vertically arranged in the collection cavity 101 to divide the space of the collection cavity 101 into a first channel 1011 and a second channel 1012 which are separated from each other at the top opening 102; wherein the first channel 1011 is connected to the top opening 102; and the top opening 102 is used for the medium containing microdroplets to enter. The medium discharge pipe 30 includes a liquid inlet 301 arranged in the second channel 1012 and extending to the outside of the collection cavity 101.
[0039] The advantage of the above arrangement is that the baffle 20 is arranged to separate the first channel 1011 through which the microdroplets enter the collection cavity 101 and the liquid inlet 301 of the medium discharge pipe 30, so as to avoid the situation that the microdroplets entering the collection cavity 101 enter the liquid inlet 301 and are mistakenly discharged from the collection cavity 101, thereby indirectly improving the yield of microdroplets by avoiding the waste of microdroplets.
[0040] Exemplarily, the distance between the liquid inlet 301 and the top opening 102 is less than the distance between the bottom wall of the partition 20 and the top opening 102. The advantage of such an arrangement is that it can avoid the microdroplets entering the first channel 1011 from falling into the liquid inlet 301 of the medium discharge pipe 30 after passing over the partition 20, and thus being wasted by being discharged out of the collection chamber 101. Exemplarily, the end of the medium discharge pipe 30 extending out of the collection chamber 101 is configured as a liquid outlet 302.
[0041] Exemplarily, the collection chamber 101 further comprises a bottom outlet 103 for discharging microdroplets. Those skilled in the art can understand that the method of using the embodiment of the present disclosure is that the liquid entering the collection chamber 101 is microdroplets and continuous phase liquid with a density difference, so after entering the collection chamber 101, the microdroplets sink to the bottom of the collection chamber 101, and the continuous phase liquid is located above the microdroplets. As the collection chamber 101 is gradually filled with microdroplets and continuous phase liquid, when the liquid surface of the continuous phase liquid reaches the liquid inlet 301, it is guided by the medium discharge pipe 30 to the collection chamber 101, that is, separated from the microdroplets, and when the microdroplets in the collection chamber 101 reach a certain capacity, the microdroplets are discharged out of the collection chamber 101 through the bottom outlet 103.
[0042] Further exemplarily, the area of the collection container 10 surrounding the bottom outlet 103 is configured as a tapered guide portion 13; the inner diameter of the guide portion 13 increases in the direction moving from the bottom outlet 103 to the top opening 102. Those skilled in the art can understand that the tapered guide portion 13 can not only accelerate the speed of discharging the microdroplets in the collection chamber 101 from the bottom outlet 103, but also avoid the microdroplets from forming residues on the bottom wall of the collection chamber 101, thereby further avoiding the waste of microdroplets and indirectly improving the yield of microdroplets.
[0043] Figure 3 Fig. 4 shows a cross-sectional view of the embodiment of the present disclosure including a liquid collecting pipe 40. Figure 4 Fig. 5 shows another view of the cross-sectional view of the embodiment of the present disclosure including a liquid collecting pipe 40. Figure 3 and Figure 4 In the example, the microdroplet collecting device further comprises a liquid collecting pipe 40 arranged in the top opening 102. The partition 20 is vertically arranged in the liquid collecting pipe 40, and the first channel 1011 and the second channel 1012 are formed in the inner cavity of the liquid collecting pipe 40; the collection chamber 101 further comprises a bottom outlet 103 for discharging microdroplets; and the liquid collecting pipe 40 is coaxial with the bottom outlet 103.
[0044] Exemplarily, the distance between the liquid inlet 301 and the top opening 102 is smaller than the distance between the bottom wall of the baffle 20 and the top opening 102 and the distance between the bottom wall of the liquid collection tube 40 and the top opening 102.
[0045] The advantage of the above arrangement is that the liquid collection tube 40 can guide the micro-droplets to fall into the area corresponding to the bottom outlet 103, so as to facilitate the later discharge of the micro-droplets from the bottom outlet 103. In addition, the range of the liquid inlet 301 that can be in communication with the liquid surface can be reduced, thereby further reducing the possibility of the micro-droplets being discharged from the liquid inlet 301, and avoiding the waste of the micro-droplets, and indirectly improving the yield of the micro-droplets.
[0046] In Figure 3 In an example, the collection container 10 comprises a detachably connected collection cylinder 11 and a cover plate 12; the space enclosed by the collection cylinder 11 and the cover plate 12 forms the collection cavity 101; the top opening 102 is formed in the cover plate 12, and the bottom outlet 103 is formed in the bottom wall of the collection cylinder 11. Exemplarily, the detachable connection between the collection cylinder 11 and the cover plate 12 is implemented as screwing or clamping. It can be understood that the detachable connection between the collection cylinder 11 and the cover plate 12 can facilitate the cleaning of the inside of the collection cavity 101 and the medium discharge pipe 30 by the operator. In this embodiment, the collection cylinder 11 and the cover plate 12 are connected by bolts. In another embodiment, the collection cylinder 11 and the cover plate 12 are clamped together.
[0047] In Figure 2 And Figure 3 In an example, the medium discharge pipe 30 has a plurality of bending portions. In other embodiments, the medium discharge pipe 30 has one bending portion, for example Figure 5 A cross-sectional view of another embodiment of the medium discharge pipe 30 in the embodiment of the disclosure shown in FIG. 6B. Figure 5 In an example, the medium discharge pipe 30 has one bending portion. The medium discharge pipe 30 comprises a vertically arranged pipe segment 31 and an inclined pipe segment 32 in communication; the liquid inlet 301 is formed in the top of the vertically arranged pipe segment 31, and the end of the inclined pipe segment 32 extends out of the collection cavity 101 and forms the liquid outlet 302. It can be understood by those skilled in the art that the fewer the bending portions of the medium discharge pipe 30, the smaller the resistance of the continuous phase liquid flowing in the medium discharge pipe 30, and the better the effect of discharging the continuous phase liquid out of the collection cavity 101, and the inclined pipe segment 32 further improves the effect of discharging the continuous phase liquid out of the collection cavity 101.
[0048] In another embodiment, the medium discharge pipe 30 is implemented to comprise a vertically arranged pipe segment and an arc-shaped pipe segment; the arc of the arc-shaped pipe segment faces upward.
[0049] Another embodiment of the present disclosure provides a microdroplet production apparatus comprising the microdroplet collection device.
[0050] In summary, the embodiments of the present disclosure provide a microdroplet collection device and a microdroplet production apparatus. The microdroplet collection device comprises a collection container, a partition and a medium discharge pipe. The collection container comprises a collection cavity with a top opening. The partition is vertically arranged in the collection cavity to divide the partial space of the collection cavity into a first channel and a second channel. The first channel is connected to the top opening, and the top opening is used for the medium containing microdroplets to enter. The medium discharge pipe comprises a liquid inlet arranged in the second channel and extending out of the collection cavity. The microdroplet production apparatus comprises the microdroplet collection device. The advantage of the above arrangement is that the microdroplets entering the first channel of the collection cavity and the liquid inlet of the medium discharge pipe are separated by the partition, so that the situation that the microdroplets entering the collection cavity enter the liquid inlet and are mistakenly discharged from the collection cavity does not occur, thereby improving the yield of microdroplets by avoiding the waste of microdroplets.
[0051] The above embodiments only exemplarily illustrate the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed by the present disclosure shall still be covered by the protection scope of the present disclosure.
