Technical Field

[0001] The utility model relates to a filter, in particular to a filter with a membrane filtering device that is easy to replace. Background Art

[0002] Membrane filtration devices use membrane technology to filter liquids or gases. The core component is the membrane. These devices are widely used in a variety of fields, including industrial wastewater treatment, food and beverage processing, biomedicine, and laboratory analysis.

[0003] In food and beverage processing, especially in the wine filtration process, membrane filtration devices can effectively remove suspended matter, microorganisms, organic matter and other impurities in the wine to ensure the purity and safety of the product. However, most of these devices are unable to quickly replace the biomembrane during the wine filtration process, resulting in the wine retaining time during the filtration process being too long, affecting the freshness and flavor of the wine.

[0019] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0020] Example 1

[0021] A filter that is easy to replace the membrane filtration device, such as Figure 1 and Figure 3 As shown, it includes a collecting cylinder 1, a box body 2, a biofilm 3, a limiting plate 6, an elastic member 601 and a guide rod 602. A collecting cylinder 1 is arranged under the box body 2. The left and right sides of the box body 2 are correspondingly slidably connected to the limiting plates 6. A through hole is provided at the end of the limiting plate 6. The guide rod 602 is fixedly connected to the box body 2 through the through hole. An elastic member 601 is wound around the guide rod 602. Both ends of the elastic member 601 are connected to the limiting plate 6 and the end of the guide rod 602. The elastic member is an elastic rubber member or a spring. In this embodiment, the elastic member 601 is preferably a spring. The front side of the box body 2 is respectively provided with upper and lower I-shaped through holes. The biofilm 3 can slide in and out through the upper and lower I-shaped through holes. A card block is fixedly connected to the bottom inside the box body 2. The card block is located below the lower I-shaped through hole and is capable of supporting the biofilm 3.

[0022] like Figure 2 As shown, the front side of the box body 2 is slidingly connected with an upper sliding plate 5 and a lower sliding plate 501, and the upper sliding plate 5 and the lower sliding plate 501 correspond to the upper and lower I-shaped through holes respectively. The upper sliding plate 5 and the lower sliding plate 501 are respectively used to block the upper and lower I-shaped through holes to prevent the wine body from being exposed; according to the utility model, the upper I-shaped through hole is arranged above the limiting plate 6, and the height of the upper I-shaped through hole is adapted to the thickness of the biofilm 3, and the height of the lower I-shaped through hole is greater than the thickness of the biofilm 3. When replacing the biofilm 3, the old biofilm 3 and the impurities on the old biofilm 3 can be taken out together to prevent the impurities from falling into the collection barrel 1.

[0023] like Figure 2 and Figure 3 As shown, the front side of the box body 2 is provided with an upper and a lower chamber, and the upper chamber and the lower chamber are used to accommodate the upper sliding plate 5 and the lower sliding plate 501 respectively. The upper chamber is located above the upper I-shaped through hole, and the lower chamber is located above the lower I-shaped through hole. The upper and lower parts of the box body 2 are respectively provided with longitudinal sliding grooves that pass through the upper and lower chambers. The upper sliding plate 5 and the lower sliding plate 501 can be lifted and slid in the corresponding sliding grooves; here, the upper chamber is more capable of accommodating the upper sliding plate 5, and the lower chamber is more capable of accommodating the lower sliding plate 501.

[0024] like Figure 2As shown, it also includes an upper sliding rod 502 and a lower sliding rod 503. The upper sliding rod 502 and the lower sliding rod 503 are respectively provided on the upper and lower sides of the front of the box body 2. The upper sliding rod 502 is slidably connected to the upper sliding plate 501, and the lower sliding rod 503 is slidably connected to the lower sliding plate 501. It is worth noting that a spring is wound around the upper sliding rod 502, and the two ends of the spring are connected to the upper sliding plate 501 and the upper part of the upper sliding rod 502. A spring is wound around the lower sliding rod 503, and the two ends of the spring are connected to the lower sliding plate 5 and the upper part of the lower sliding rod 503. The design of the spring makes the upper and lower I-shaped through holes more tightly closed to prevent the wine from leaking out.

[0025] like Figure 3 and Figure 4 As shown, a vacuum pump 4 and a connecting pipe 401 are also included. The outside of the collecting cylinder 1 is fixedly connected to the vacuum pump 4, and the vacuum pump 4 is connected to the connecting pipe 401. The end of the connecting pipe 401 away from the vacuum pump 4 passes through the collecting cylinder 1 and enters the interior. When the wine is filtered, the vacuum pump 4 is started, and the vacuum pump 4 creates a vacuum environment in the collecting cylinder 1 through the connecting pipe 401, so that the suction force inside the collecting cylinder 1 is increased, thereby increasing the filtration speed of the wine.

[0026] like Figure 4 As shown, a baffle 402 is arranged obliquely inside the collecting cylinder 1. The baffle 402 is located above the end of the connecting pipe 401 away from the vacuum pump 4. The inclined setting of the baffle can prevent the wine from splashing during the filtration process and prevent the vacuum pump 4 from causing mechanical failure.

[0027] When in use, first fix the box 2 above the collecting cylinder 1, and then place the biofilm 3 horizontally above the block. At this time, the wine to be filtered can be poured from above the box 2 to filter the wine. When the biofilm 3 needs to be replaced, the upper sliding plate 501 on the front side of the outer surface of the box body 2 can be lifted upward, and the upper sliding plate 501 slides upward along the upper sliding rod 502 and is received into the upper chamber. Then, the new biofilm 3 is pushed into the interior of the box body 2 through the upper I-shaped through hole, and the new biofilm 3 is fixed above the limiting plate 6 by the limiting plate 6. At the same time, the new biofilm 3 plays a filtering role to filter the poured wine. Then, the upper sliding plate 5 is released, and the upper sliding plate 5 moves downward to close the I-shaped through hole. Then, the lower sliding plate 501 is lifted upward, and the lower sliding plate 501 slides upward along the lower sliding rod 503 and is received into the lower chamber. Then, the old biofilm 3 can be slowly pulled outward through the I-shaped through hole below to remove the old biofilm 3 and impurities such as suspended matter, microorganisms, and organic matter generated during the filtering process of the wine. Then, the lower sliding plate 501 is released, and the lower sliding plate 501 moves downward to close the I-shaped through hole below. Then, the limiting plates 6 on both sides are pulled outward, and the elastic parts 601 on both sides shrink. The limiting plates 6 on both sides no longer restrict the new biofilm 3, and the biofilm 3 slides down along the inner wall of the box body 2 to the block on the inner wall of the box body 2, thereby replacing the original biofilm 3 to filter the wine body, and continuing to maintain the filtering state of the filter, finally realizing the replacement of the biofilm 3 during the filtration process, and realizing the quick replacement of the biofilm during use.
