Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to a device for collecting and treating waste culture media used in vaccine production. Background Technology

[0002] Vaccine production generates a large amount of waste culture media. This waste may contain live microorganisms, nutrients, and chemical additives. Improper handling can easily lead to biosafety risks, environmental pollution, or cross-contamination.

[0003] Traditional devices require the entire protective cover to be opened, exposing all openings, regardless of the collection volume. This leads to a large exchange of airflow between the inside and outside of the device. If waste culture medium containing live vaccine strains is collected, the airflow carrying microorganisms is prone to leakage, which not only increases the risk of infection for operators but may also cause cross-contamination of the clean area environment. Moreover, most traditional devices rely solely on the gravity of the protective cover for sealing and lack a dedicated sealing structure. When collecting culture medium containing volatile components or corrosive liquids, liquid leakage and gas evaporation are likely to occur, which does not meet the biosafety requirements for vaccine production. Utility Model Content

[0004] The purpose of this invention is to provide a waste culture medium collection and treatment device for vaccine production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste culture medium collection and treatment device for vaccine production, comprising a collection box, a large protective cover movably mounted on the collection box, a small protective cover movably mounted at the center of the large protective cover, and a handle fixedly mounted on the top of the small protective cover;

[0006] Both the small and large protective covers are fixedly installed with U-shaped buckles on their tops. Connecting parts are movably inserted into the two U-shaped buckles. A locking bolt is threaded onto one of the U-shaped buckles, and the locking bolt is supported at the corresponding position on the upper surface of the connecting part.

[0007] Preferably, the connectors are arranged in pairs, and the connectors and handles are arranged parallel to each other.

[0008] Preferably, the small protective cover and the collection box are arranged concentrically.

[0009] Preferably, an outer positioning hoop is fixedly fitted on the outer wall of the small protective cover, the outer positioning hoop is movably engaged with the collection box, and an inner sealing ring is coaxially fixedly installed at the bottom of the outer positioning hoop.

[0010] Preferably, the collection box has a recessed groove corresponding to the outer positioning hoop and the inner sealing ring.

[0011] Preferably, a filter screen is provided inside the collection box, a pull rod is fixedly installed on the top of the filter screen, a support base is fixedly installed on the bottom of the filter screen, and the support base is fixedly installed on the inner wall of the collection box.

[0012] Preferably, the lower end of the pull rod is inserted into the support base through the filter screen.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When collecting small amounts of waste culture medium, only the small protective cover needs to be opened, without exposing the entire collection box opening. On the one hand, the small opening design reduces the amount of air exchange between the inside and outside when the device is opened and closed, preventing the leakage of air carrying microorganisms from the collection box. On the other hand, the small protective cover, through the double seal of the outer positioning clamp and the inner sealing ring, combined with the fitting design of the collection box's sinking groove, can prevent liquid leakage or gas evaporation, meeting the biosafety level requirements for vaccine production. When collecting large amounts of waste culture medium, the large protective cover can be opened completely, exposing the top of the collection box. Compared with traditional small-opening devices, the collection speed is faster, and there is no need for multiple opening and closing, reducing repetitive work for operators.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a waste culture medium collection and treatment device for vaccine production. The collection box 1 is a hollow box structure with an open top. An installation groove adapted to a large protective cover 2 is opened at the top edge of the box. The large protective cover 2 is installed at the top opening of the collection box 1 by a movable connection, which can realize the overall opening and closing. At the center of the top opening of the collection box 1, a circular opening adapted to a small protective cover 3 is also opened. The small protective cover 3 is movably installed in the circular opening, and the small protective cover 3 is concentrically set with the collection box 1 to ensure balanced force and sealing effect.

[0022] An outer positioning hoop 8 is welded and fixed to the outer wall of the small protective cover 3. The outer diameter of the outer positioning hoop 8 is adapted to the inner diameter of the circular opening on the collection box 1, and can be movably locked into the circular opening of the collection box 1. An inner sealing ring 9 is coaxially and fixedly installed at the bottom of the outer positioning hoop 8 by adhesive. A recessed groove is opened on the collection box 1 at the position corresponding to the outer positioning hoop 8 and the inner sealing ring 9. When the recessed groove cooperates with the outer positioning hoop 8 and the inner sealing ring 9, a double sealing structure can be formed to prevent airflow or liquid leakage in the collection box 1.

[0023] Both the small protective cover 3 and the large protective cover 2 have U-shaped buckles 5 fixedly installed on their tops by welding. The openings of the two U-shaped buckles 5 are in the same direction and are in the same vertical plane. They are used to insert the connector 6. The connector 6 is set in pairs and its length is slightly greater than the distance between the two U-shaped buckles 5. It can be simultaneously inserted into the two U-shaped buckles 5 to limit the vertical movement of the small protective cover 3. The U-shaped buckle 5 near the small protective cover 3 has a threaded hole. The locking bolt 7 is threaded to the U-shaped buckle 5 through the threaded hole. After tightening the locking bolt 7, its lower end can be supported on the corresponding position on the upper surface of the connector 6 to further fix the connector 6 and prevent it from falling out of the U-shaped buckle 5 during use.

[0025] Connection between collection box and filter screen

[0026] A filter screen 10 (preferably made of 316L stainless steel, with mesh size set according to the solid-liquid separation requirements of the waste culture medium, typically 0.22-1mm) is installed near the center inside the collection box 1 to achieve solid-liquid separation of the waste culture medium. A support base 12 is welded and fixed to the bottom of the filter screen 10. The support base 12 has a ring or rectangular structure, and its outer wall is fixed to the inner wall of the collection box 1 by welding or bolts to provide stable support for the filter screen 10.

[0027] A pull rod 11 is fixedly installed at the top center of the filter screen 10 by welding. The pull rod 11 is a cylindrical structure, and its lower end passes through the filter screen 10 and is movably inserted into the positioning hole opened on the support base 12. The positioning hole is adapted to the outer diameter of the pull rod 11, which can limit the horizontal displacement of the filter screen 10. At the same time, the fixed connection design between the pull rod 11 and the filter screen 10 makes it easy for the operator to remove the filter screen 10 from the collection box 1 by pulling the pull rod 11, so as to realize the individual disassembly, cleaning or replacement of the filter screen 10.

[0028] Working principle:

[0029] There are two ways to open the large protective cover 2. When dealing with a small amount of waste culture medium, you can choose to open only the small protective cover 3, pull out the connector 6 inside the U-shaped buckle 5. The connector 6 is pulled out from the U-shaped buckle 5, and the vertical movement of the small protective cover 3 is no longer limited. By applying a pulling force to the handle 4, the small protective cover 3 is moved. After the small protective cover 3 is pulled out, the opening on the collection box 1 at the position of the small protective cover 3 is exposed. The waste culture medium can be placed through this opening. After closing, it is sealed by the outer positioning hoop 8 and the inner sealing ring 9 to prevent the airflow inside the waste culture medium from leaking out. The small opening can also reduce the amount of airflow exchange when the small protective cover 3 is opened to a certain extent. When the waste culture medium is put in, the waste culture medium comes into contact with the filter screen 10, and the liquid flows downward to achieve solid-liquid separation. At the same time, the filter screen 10 can also be separated by pulling rod 11. When dealing with a large amount of waste culture medium, you can choose to open the large protective cover 2 to quickly put in the waste culture medium.
