Description

Technical Field

[0001] This utility model relates to the field of biomedical technology, and in particular to a two-stage high-efficiency filtration device. Background Technology

[0002] In the field of biomedicine, the extraction of biological fluids from bovine gastric juice is a key production step. In this process, the bovine gastric juice first needs to be pretreated to remove impurities and unwanted components. Through effective filtration, it can be ensured that the extracted biological fluids are pure and meet the quality requirements of subsequent production or research. This step is not only crucial to ensuring the safety and efficacy of the product, but also an indispensable part of the entire production process.

[0003] Filtration requires a filtration device. In the existing technology, a simple single-layer filter cartridge is generally used. This method has obvious drawbacks: the filtration effect of a single-layer filter cartridge is limited, and it cannot completely remove all impurities and unwanted components from bovine gastric fluid, thereby affecting the purity and quality of the extracted biological fluid, which in turn has an adverse impact on the results of subsequent production or research. Moreover, during the filtration process, the flow filtration relies on the gravity of the liquid, resulting in a slow flow rate and low collection efficiency. Therefore, this utility model proposes a two-stage high-efficiency filtration device to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a two-stage high-efficiency filtration device. This two-stage high-efficiency filtration device filters liquids through a cylindrical body. During filtration, the liquid first passes through a disc body and undergoes first-stage filtration using the second filter holes. Then, the liquid flows into the inner cylinder and undergoes second-stage filtration using the first filter holes. This two-stage filtration results in better performance and improves liquid quality.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a two-stage high-efficiency filtration device, including a cylinder and a collection tank, wherein a sealing cover is provided on the top of the collection tank, and a connecting pipe is provided on one side of the top of the sealing cover, the connecting pipe being used to connect a vacuum pump;

[0006] The cylinder has an inner cylinder inside, and the lower and bottom outer sides of the inner cylinder are provided with first filter holes. A sealing ring is provided between the upper inner side of the cylinder and the outer side of the inner cylinder. A disc is provided above the inner cylinder, and the bottom of the disc is provided with a second filter hole. A support edge is provided above the outer side of the disc, and the support edge is mounted on the inner cylinder. A conduit assembly is connected between the lower side of one side of the cylinder and the lower side of the collection bucket, and a cover is provided on the top of the cylinder.

[0007] A further improvement is that the conduit assembly includes a first conduit and a second conduit, the first conduit being located below one side of the cylinder, the second conduit being located below one side of the collection bucket, a flexible hose being connected between the first conduit and the second conduit, and a first valve being provided on both the first conduit and the second conduit.

[0008] A further improvement is that a first handle is provided at the middle position of the top of the cover, and a first handle is provided at the middle of both sides of the cylinder.

[0009] A further improvement is that: both the upper part of the outer side of the collection bucket and the lower part of the outer side of the sealing cover are provided with sealing edges, and the two sets of sealing edges are fixed together by fastening bolts.

[0010] A further improvement is that a second handle is provided at the middle position of the top of the sealing cap, a second handle is provided at the middle of both sides of the collection bucket, and a second valve is provided on the connecting pipe.

[0011] A further improvement is that a support block is provided at the middle position of the bottom of the inner cylinder, and an air cushion is provided on the support block, with the lower part of the inner cylinder supported on the air cushion.

[0012] A further improvement is that an air duct is connected to the lower part of the air cushion body, and the lower end of the air duct extends out of the cylinder body, and the lower end of the air duct is connected to a compression airbag.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model filters liquid through a cylinder. During filtration, the liquid first passes through a disc and undergoes first-stage filtration using the second filter hole. Then, it flows into the inner cylinder and undergoes second-stage filtration using the first filter hole. This two-stage filtration results in better performance and improves liquid quality. The filtered liquid then enters a collection tank through a conduit assembly. During the collection process, the conduit is connected to a vacuum pump to generate suction, allowing the filtered liquid inside the cylinder to flow into the collection tank more quickly, thus improving collection efficiency.

[0015] 2. In this utility model, the upper part between the inner cylinder and the inner side of the cylinder is sealed by a sealing ring. After long-term use, there is a problem of jamming. Therefore, when the inner cylinder needs to be removed for maintenance, simply press the air bladder to inflate the air cushion. The expansion of the air cushion will push the inner cylinder upward, making it easy to remove. This makes it a versatile product. Attached Figure Description

[0029] Example 2

[0030] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a two-stage high-efficiency filtration device, including a cylindrical body 1 and a collection tank 2. A sealing cover 3 is provided on the top of the collection tank 2, and a connecting pipe 4 is provided on one side of the top of the sealing cover 3. The connecting pipe 4 is used to connect a vacuum pump.

[0031] The inner cylinder 1 has an inner cylinder 5 inside, and the lower and bottom outer sides of the inner cylinder 5 are provided with first filter holes 6. A sealing ring 7 is provided between the upper inner side of the inner cylinder 1 and the outer side of the inner cylinder 5.

A support edge 10 is provided above the outer side of the disc 8, and the support edge 10 is mounted on the inner cylinder 5. A conduit assembly is connected between the lower side of one side of the cylinder 1 and the lower side of one side of the collection tank 2, and a cover 11 is provided on the top of the cylinder 1. In use, the liquid is filtered by the cylinder 1. During filtration, the liquid first passes through the disc 8 and undergoes first-stage filtration using the second filter hole 9, and then flows into the inner cylinder 5 for second-stage filtration using the first filter hole 6. This secondary filtration improves the effect and enhances the quality of the liquid. The filtered liquid enters the collection tank 2 through the conduit assembly. During the collection process, the connecting pipe 4 is connected to a vacuum pump to generate suction, allowing the filtered liquid inside the cylinder 1 to flow into the collection tank 2 more quickly, improving collection efficiency.

The filtered liquid then enters the collection tank 2 through the conduit assembly. During collection, the connecting pipe 4 is connected to a vacuum pump, generating suction force to allow the filtered liquid inside the cylinder 1 to flow more quickly into the collection tank 2, improving collection efficiency. Simultaneously, inside the cylinder 1, the upper part between the inner cylinder 5 and the inner side of the cylinder 1 is sealed by a sealing ring 7. After prolonged use, this can lead to jamming.
