Description

Technical Field

[0001] The present application relates to the field of filtering devices, and in particular to a filtering device for detecting cosmetic microorganisms. Background Art

[0002] With the development of biotechnology, in the field of cosmetics, more and more active ingredients of cosmetics are extracted through effective microbial fermentation.

[0003] During the microbial fermentation process, the concentration of effective microorganisms, types of foreign bacteria, concentration of foreign bacteria, and temperature in the fermentation system need to be strictly controlled in order to successfully produce effective ingredients of corresponding purity. At present, during the microbial fermentation process, it is necessary to regularly extract sample liquid from the fermentation tank, and then filter it with a filter membrane. According to the analysis results of the microorganisms on the filter membrane, the types of foreign bacteria are obtained and the concentration of effective microorganisms and foreign bacteria concentration are calculated.

[0004] However, frequent opening of the fermentation tank for sampling can easily cause exogenous contamination, and after taking out, the samples need to be transferred to other devices for filtration. Since the pore size of the filter membrane for filtering microorganisms is small and the filtration time is long, it will also further increase the severity of exogenous contamination.

The fermentation liquid is sampled through the filter box connected to the fermentation tank, and there is no need to enter the fermentation tank from the outside to take samples, which reduces the possibility of exogenous contamination. In addition, the filtration operation is directly carried out in the filter box through the filter membrane, which further reduces the possibility of exogenous contamination during the long filtration process;

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] The present application discloses a filtering device for detecting cosmetic microorganisms. Figure 1 As shown in the figure, a filtering device for detecting cosmetic microorganisms includes a filter box 1 and a filter membrane 8. The filter box 1 includes a feed chamber and a drainage chamber for being movably connected to a fermentation tank. The filter membrane 8 is detachably arranged in the filter box 1 and the drainage chamber and the feed chamber are separated by the filter membrane 8. A feed pipe 2 and a drainage pipe 7 are fixed on the filter box 1. The feed pipe 2 is connected to the feed chamber, and the drainage pipe 7 is connected to the drainage chamber. Valves 3 are installed on both the feed pipe 2 and the drainage pipe 7.

[0026] Reference Figure 2 , multiple filter membranes 8 are provided, the drainage cavity is located between the multiple filter membranes 8, and the number of feed cavities is consistent with the number of filter membranes 8. Correspondingly, multiple feed pipes 2 are movably connected to the filter box 1, and the feed pipes 2 are connected and arranged in a one-to-one correspondence with the feed cavities. In the embodiment of the present application, two filter membranes 8 are provided, and the two filter membranes 8 are perpendicular to the inner bottom wall of the filter box 1 and are arranged in parallel with each other in the filter box 1, dividing the filter box 1 into three spaces, wherein the drainage cavity is the space between the two filter membranes 8, and the feed cavity is the other two spaces. Two corresponding feed pipes 2 are provided, and the feed pipes 2 are located on the outer wall of the filter box 1 to stagger with the disassembly direction of the filter membrane 8.

[0027] In other embodiments, the number of filter membranes 8 can be three, four, five, etc., and the ends are connected and distributed in a circle, and the shape of the filter box 1 can also be correspondingly set to a multi-prism, so that the multiple filter membranes 8 divide the filter box 1 into a drainage chamber and a feed chamber equal to the number of filter membranes 8, so that the fermentation liquid sampled in different time periods can be filtered simultaneously, and the multiple sample liquids obtained in the same time period can also be used for repeated experiments, which greatly expands the efficiency and accuracy of microbial detection.

[0028] Reference Figure 2 and Figure 3The top of the filter box 1 is provided with two insertion holes 6, and two installation frames 4 for installing the filter membrane 8 are slidably arranged in the insertion holes 6. The filter membrane 8 is located between the two installation frames 4, and the two membrane surfaces are respectively abutted against the frame bodies of the two installation frames 4, and the two installation frames 4 are hinged to each other. Further, in order to facilitate the positioning of the filter membrane 8, the sides of the two installation frames 4 close to each other are provided with stepped surfaces, so that when the two installation frames 4 are combined, the filter membrane 8 is embedded in the area formed by the combination of the two installation frames 4, thereby reducing the possibility of the filter membrane 8 falling off.

[0029] Further, the possibility of deformation or misalignment of the filter membrane 8 between the two mounting frames 4 is reduced. Figure 3 On the side of the mounting frame 4 close to the filter membrane 8, an anti-skid structure 9 for increasing the friction between the filter membrane 8 and the mounting frame 4 is provided. In the embodiment of the present application, the anti-skid structure 9 is a rubber ring, which is embedded on the side of the mounting frame 4 close to the filter membrane 8 and movably abuts against the filter membrane 8. In other embodiments, the anti-skid structure 9 can also be an anti-skid protrusion or anti-skid pattern provided on the mounting frame 4. In order to protect the integrity of the filter membrane 8, a rubber ring is preferably used in the present application.

[0030] Reference Figure 2 and Figure 3 In order to facilitate the removal of the filter membrane 8 from the filter box 1, a handle is fixed on the side of the installation frame 4. The handle is located outside the filter box 1, that is, the top of the installation frame 4 is flush with the opening plane of the jack 6, and the handle is located at the top of the installation frame 4. Further, in order to clamp the two installation frames 4 in the process of pulling out the installation frames 4, the handle includes two split handles 5. The split handles 5 are fixed to the installation frames 4 in a one-to-one correspondence. The sides of the two split handles 5 that are close to each other are both flat. When the two installation frames 4 are combined, the two split handles 5 are combined into a handle, and when the two split handles 5 are held to pull out the installation frames 4, the two installation frames 4 still do not rotate relative to each other, thereby restricting the filter membrane 8 between the two installation frames 4.

[0031] Reference Figure 2 In order to improve the stability of the installation frame 4 during installation and the stability of the filter membrane 8 when filtering microorganisms under water pressure, a limiting groove 10 for the sliding insertion of the installation frame 4 is provided on the inner wall of the filter box 1, and the installation frame 4 is embedded in the limiting groove 10. Specifically, the limiting groove 10 is arranged in a U shape on the inner wall of the filter box 1, and its opening is the insertion hole 6, so that when the installation frame 4 is inserted into the filter box 1 through the insertion hole 6, it moves to the inner wall of the filter box 1 under the guidance of the limiting groove 10.

[0032] The implementation principle of the filtering device for cosmetic microbial detection in the embodiment of the present application is as follows: when it is necessary to perform regular detection of microorganisms, open valve 3 to allow the fermentation liquid to flow into the feed chamber, and wait until the next regular detection, open another valve 3 to allow the fermentation liquid to flow into another feed chamber, thereby achieving simultaneous filtration and detection of fermentation liquids of different time scales, and opening multiple valves 3 at the same time, multiple samples of fermentation liquid at the same time can be filtered and detected simultaneously. During detection, hold the two-part handle 5 to pull the installation frame 4 out of the filter box 1, and then drive the two-part handle 5 to move away from each other, so that the two installation frames 4 rotate in the direction away from each other, and finally take out the filter membrane 8 for inspection.
