Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal, in particular to a filtering device for vitamin K2 fermentation broth. Background Technique

[0002] In the field of biopharmaceuticals, the active ingredients of drugs generally belong to the metabolites of microorganisms. As a fat-soluble vitamin, vitamin K2 can also be prepared by modern microbial fermentation methods. Preparing vitamin K2 by the microbial method has more advantages than chemical synthesis, such as lower raw material costs, less environmental pollution, and higher biological activity of the products.

[0003] When filtering the vitamin K2 fermentation broth, a filtering device is usually required. The current filtering device has a relatively simple structure. Usually, only a filter screen is arranged in the filtering device, and the vitamin K2 fermentation broth is filtered through the filter screen. However, this filtering method often has certain defects. If the filter holes on the filter screen are too large, the smaller particles in the vitamin K2 fermentation broth cannot be filtered, resulting in a relatively large filtering effect; if the filter holes on the filter screen are too small, the filter screen is prone to clogging, which brings inconvenience to the staff; in addition, after the filtering device is used, it is not convenient to clean.

[0004] Therefore, we propose a filtering device for vitamin K2 fermentation broth to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems mentioned above.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a filtering device for vitamin K fermentation broth, including a filtering cylinder and a liquid discharge port opened at the lower part of the filtering cylinder, characterized in that: a support ring is fixedly installed inside the filtering cylinder, a screening net for screening the filtration of fine particles is installed on the support ring, a screening cylinder for screening larger particles is installed on the screening net, a cover plate for pressing the screening cylinder is installed at the top of the filtering cylinder. When the fermentation broth in the screening cylinder flows into the upper part of the screening net, the larger impurities in the fermentation broth are filtered through the screening cylinder. When the fermentation broth on the screening net falls into the lower part of the filtering cylinder, the smaller particles in the fermentation broth can be filtered through the screening net.

[0007] Further: a plurality of positioning protrusions are fixedly arranged at equal intervals along the circumferential direction at the top of the support ring, and grooves matched with the positioning protrusions are opened at the lower part of the screening net.

[0008] Further: an installation ring is fixed at the top of the screening net, and an external thread is arranged on the outer surface of the installation ring. An internal thread matched with the external thread is installed at the lower part of the screening cylinder.

[0009] Further: The cover plate includes a mounting sleeve threadedly mounted at the opening of the filter cartridge, and a conical funnel is provided at the lower part of the mounting sleeve. A pressing ring for pressing the screening cylinder is fixed at the bottom of the conical funnel.

[0010] Further: Mounting seats are fixedly arranged on the outer surface of the filter cartridge at equal intervals along the circumferential direction, and a plurality of mounting seats are mounted on the same mounting frame by bolts.

[0011] Further: An annular protrusion is fixed at the edge of the top of the screening mesh, and the outer surface of the annular protrusion is attached to the inner side wall of the filter cartridge.

[0012] Advantages of the utility model:

[0013] In the utility model, a screening mesh and a screening cylinder are arranged inside the filter cartridge. The screening cylinder can filter larger particulate matters in the vitamin K2 fermentation broth, reducing the phenomenon that smaller particles are blocked inside the screening cylinder; the screening mesh can filter smaller particulate matters in the vitamin K2 fermentation broth, thereby improving the filtering effect on vitamin K2 and enhancing the use effect of the device.

[0014] The filter cartridge and the cover plate of the utility model are connected in a detachable manner, so that the screening mesh and the screening cylinder can be taken out from the inside of the filter cartridge, facilitating the cleaning of the inside of the filter cartridge; the screening mesh and the screening cylinder are connected in a detachable manner, enabling them to be cleaned separately after disassembly, providing convenience for the staff.

[0021] Embodiments of the present utility model:

[0022] A filtering device for vitamin K2 fermentation broth, comprising a filtering cylinder 1. A plurality of mounting seats 8 are equidistantly installed on the outer surface of the filtering cylinder 1 along the circumferential direction. Through the arrangement of the plurality of mounting seats 8, the filtering cylinder 1 can be installed on a mounting frame (the mounting frame is shown in the figure) for use. A liquid discharge port 2 is opened at the center of the bottom of the filtering cylinder 1. Through the arrangement of the liquid discharge port 2, the fermentation broth in the filtering cylinder 1 can be discharged. A liquid inlet is opened at the top of the filtering cylinder 1. Through the arrangement of the liquid inlet, the fermentation broth can be put into the interior of the filtering cylinder 1.

[0023] A support ring 3 is fixed to the inner side wall of the lower part of the filtering cylinder 1. Specifically, a plurality of positioning protrusions 31 are equidistantly fixed on the top of the support ring 3 along the circumferential direction, and a plurality of grooves for cooperating with the positioning protrusions 31 are equidistantly opened at the bottom of the screening mesh 4 along the circumferential direction.

A pressing ring 63 is fixed to the bottom of the conical funnel 62. Through the arrangement of the pressing ring 63, the screening cylinder 5 is pressed to prevent the screening cylinder 5 from shaking during use.

[0026] When filtering the vitamin K2 fermentation broth, first pour the vitamin K2 fermentation broth into the screening cylinder 5. Through the screening cylinder 5, larger particulate matters in the vitamin K2 fermentation broth can be filtered, thus completing the primary filtration.
