Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a microbial filtering device. Background Art

[0002] Microorganisms include a large group of organisms such as bacteria, viruses, fungi, as well as some small protozoa, microalgae, etc. They are tiny in size and closely related to humans. They cover a wide variety of beneficial and harmful types and are widely involved in many fields such as food, medicine, industry and agriculture, environmental protection, sports, etc. In Chinese textbooks, according to the categories and morphological structures of microorganisms, they are generally classified into bacteria, viruses, and fungi. Some microorganisms can be seen with the naked eye, such as mushrooms, ganoderma lucidum, shiitake mushrooms, etc. that belong to fungi. There are also microorganisms that are a type of "acellular organisms" composed of only a few components such as nucleic acids and proteins.

[0003] During the microbial limit inspection test, the sample test solution needs to be filtered and then collected for cultivation. However, the existing filtering devices have poor filtering effects on microorganisms. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a microbial filtering device with good filtering effects.

[0005] The technical solution of the utility model is as follows:

[0006] A microbial filtering device includes a filtering cavity and a filtering plate. A filtering chamber is arranged inside the filtering cavity. A feed inlet communicating with the filtering chamber is opened at the top of the filtering cavity. The filtering plate is arranged on the feed inlet. The filtering plate successively includes a protective layer, a filtering layer, a separation layer, and a support layer from top to bottom. A number of randomly distributed filtering channels are formed between the protective layer, the filtering layer, the separation layer, and the support layer. A discharge outlet communicating with the filtering chamber is opened at the bottom of the filtering cavity.

[0007] Further, the filtering chamber is composed of a funnel and a discharge pipeline which are connected up and down.

[0008] Further, there are two layers of support layers above and below the support layer of the filtering plate.

[0009] Further, the filtering channels are non-vertical and diverse curves.

[0010] Further, the cross-sections of the protective layer, the filtering layer, and the separation layer are all wavy.

[0011] Further, the cross-section of the support layer is two wavy line segments staggered up and down, and support bars are arranged between the upper and lower two wavy line segments.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: By adding a filter plate to the filter cavity, the filter plate sequentially includes a protective layer, a filtering layer, a separation layer, and a support layer from top to bottom. A number of randomly distributed filter channels are formed between the protective layer, the filtering layer, the separation layer, and the support layer. This structural design has a good filtering effect on microorganisms, provides good support and protection for the filter membrane, and can effectively filter and separate microorganisms from the diluent or buffer solution.

[0023] In order to make the objectives, technical solutions, and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.

[0025] Embodiment

[0026] Please refer to Figure 1, this embodiment provides a microbial filtration device, which includes a filtration cavity 1 and a filter plate 2. Inside the filtration cavity 1, there is a filtration chamber 3, which is composed of a funnel 31 and a discharge pipe 32 connected vertically. At the top of the filtration cavity 1, there is a feed inlet communicating with the funnel 31. The filter plate 2 is arranged at the feed inlet. At the bottom of the filtration cavity 1, there is a discharge outlet 11 communicating with the discharge pipe 32.

[0027] When it is necessary to filter the separation of microorganisms from the diluent or buffer solution, a filter membrane is placed on the filter plate 2. The staff pours the liquid containing microorganisms onto the filter membrane, and then filters and separates the microorganisms from the diluent or buffer solution through the filter plate 2. The diluent or buffer solution then drains into the filtration chamber 3, is concentrated by the funnel 31 and then discharged from the discharge outlet 11 through the discharge pipe 32. This device has a simple structure and is easy to operate.

[0028] Combined Figure 2 As shown, specifically, the filter plate 2 successively includes a protective layer 21, a filtration layer 22, a separation layer 23 and two support layers 24 from top to bottom. The cross-sections of the protective layer 21, the filtration layer 22 and the separation layer 23 are all wavy. The cross-section of the support layer 24 is two wavy line segments staggered up and down. There is a support bar 241 between the upper and lower two wavy line segments. A number of randomly distributed filtration channels 25 are formed between the protective layer 21, the filtration layer 22, the separation layer 23 and the support layer 24. The filtration channels 25 are non-vertical multi-style curves. Through this structural design, the filtration effect on microorganisms is good, the support and protection for the filter membrane are good, and the microorganisms can be effectively filtered and separated from the diluent or buffer solution.
