Description

Technical Field

[0001] The utility model relates to the technical field of separation and filtration equipment, in particular to a strain separation and filtration equipment. Background Art

[0002] The centrifugal sedimentation method is to centrifuge the fermentation broth of the strain to allow the bacteria to precipitate to the bottom of the centrifuge tube, then pour out the supernatant and finally collect the bacterial precipitate.

[0003] The high-density strain fermentation broth after cultivation needs to be separated and collected. Currently, there are two common methods for separating and collecting strains: one is to centrifuge the fermentation broth. After centrifugation, the strain fermentation broth will have a stratification phenomenon of precipitate rich in accumulated strains and clear liquid with low content of strains, and the strain precipitate is collected; or directly use the filtration method to complete the filtration through equipment such as filter funnels, vacuum filtrate devices, and filter membranes.

[0004] However, if the precipitate is collected directly after the clear liquid is poured out after centrifugation, the amount of strain collected will be low, which is not in line with production efficiency. The direct filtration method is less efficient than the centrifugation method, and the strains are separated by filtration throughout the process, which makes the separation time-consuming and not applicable to large-scale industrial production of strains, and its separation efficiency is not high.

[0005] In summary, we need to consider how to separate strains to the greatest extent possible while improving the efficiency of strain separation; in view of this, we propose a strain separation filtration device. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-8 The utility model describes the above technical solution in detail through the following embodiments:

[0037] The separation and filtration part is arranged in the clear liquid tank 1, and comprises a processing unit 5 for containing the fermentation liquid to be separated, a limiting base 7 is installed on the processing unit 5, and a filter cover 9 for collecting strains is arranged in the limiting base 7;

[0038] The lifting part includes a support plate 3 installed on the liquid clearing bin 1, and a top plate 4 is connected to the support plate 3 through three cylinders 11; the processing unit 5 of this embodiment is rotatably installed on the top plate 4, such as Figure 4and Figure 8 In the structure shown, a driving motor 10 is installed on the top plate 4 , and a transmission belt 6 is installed between the output shaft of the driving motor 10 and the liquid guide port 511 provided on the processing unit 5 .

[0039] like Figure 6-8 As shown in the structure, the processing unit 5 of this embodiment includes a filtrate bin 51 equipped with a rotating baffle ring 52, a liquid guide port 511 and a processing chamber 512 are provided on the filtrate bin 51, and a bottom convex plate 53 is connected to the filtrate bin 51 below by multiple vertical connecting rods 54; a centrifugal chamber for allowing the fermentation liquid to flow outward to the filter cover 9 for separation and filtration is provided between the filtrate bin 51 and the bottom convex plate 53, and the centrifugal chamber allows the fermentation liquid to rotate along the axis during the rotation process, thereby achieving the effects of centrifugation and filtration; a support plate 55 for detachably mounting a limiting base 7 is provided around the bottom convex plate 53; an insertion chamber 701 for inserting the filter cover 9 is provided inside the limiting base 7, and a pressure plate 8 for limiting the filter cover 9 is detachably installed on the limiting base 7; in this embodiment, the pressure plate 8 is directly fixed to the limiting base 7 by screws, and the limiting base 7 is fixed to the support plate 55 at the same time.

[0040] In order to discharge the filtrate, a drainage hole 702 is provided on the limiting base 7, and a filter hole for screening strains is provided on the filter cover 9, so that the filtrate passes through the filter hole and the drainage hole 702 and gathers in the clear liquid bin 1 and is discharged through the drainage pipe 101.

[0041] In order to maintain synchronous rotation capability, a limit plug hole 901 is provided on the filter cover 9 for being inserted along the vertical connecting rod 54. In order to facilitate the removal of the strains separated in the collection cover of the filter cover 9, this embodiment adopts two symmetrically arranged semi-annular filter covers 9 to facilitate the collection and removal of the filter cover 9.

The fermentation liquid obtains the centrifugal force of the principle axis at the bottom centrifugal chamber position through rotation, so that the fermentation liquid passes through the filter cover 9 to complete the strain separation. After separation, the clear liquid is discharged from the drainage hole 702 to the inside and outside of the clear liquid bin 1; finally, the processing unit 5 installed with the limiting base 7 is lifted upward by the cylinder 11, so that the limiting base 7 rises, and the filter cover 9 with the separated strains inside can be removed by removing the lower pressure plate 8.
