Description

Technical Field

[0001] This utility model relates to a siphon-type seawater filtration device. Background Technology

[0002] In marine shellfish seed production, single-celled algae are the basic food source for shellfish seedlings, and their cultivation is crucial to the success of seedling production. During the primary algae cultivation process, the seawater needs to be further finely filtered through sand to remove impurities and ensure optimal cultivation results. Fine filtration typically uses a vacuum filtration system, including a vacuum pump, filter bottles, and filter membranes. This entire system is expensive, time-consuming, and energy-intensive.

[0003] CN 202682874 U discloses a simple and rapid seawater filter, comprising a mineral water bottle with its opening facing downwards and the bottom removed, the bottle opening sealed with silk sieve; inside the bottle, from bottom to top, are layers of absorbent cotton wrapped in gauze, activated carbon, fine sand, and coarse sand, with gauze placed between the fine and coarse sand and on the surface of the coarse sand. A latex tube with a glass tube connected to one end can also be provided above the mineral water bottle, with the other end of the latex tube located at the center of the top of the mineral water bottle. In use, it is inserted into a clean container to be filtered seawater, with one end of the glass tube directly inserted into the container containing settled seawater. A bulb syringe is used to forcefully siphon seawater into the filter. However, the filter media composition of this application is complex, and there are no components to secure the filter media. During use, the entire device is immersed in water, and the filter media easily detaches from the device; using a bulb syringe for siphoning is inconvenient. Utility Model Content

[0004] The main objective of this invention is to provide a siphon-type seawater filtration device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A siphon-type seawater filtration device includes a funnel, a hose, a pumping airbag, and a funnel cover; wherein, filter media is placed inside the funnel, and a funnel cover with a cap hole is fixed on the funnel, and the filter media is fixed between the funnel and the funnel cover; the pumping airbag is disposed on the hose, one end of the hose is connected to the bottom of the funnel, and the other end is connected to the pumping airbag.

[0007] Furthermore, the filter material is degreased cotton.

[0008] Furthermore, a fixing structure is provided between the funnel cover and the funnel.

[0009] Furthermore, the fixing structure is a snap-fit ​​fixing.

[0010] Furthermore, the fixing structure is threaded.

[0011] Furthermore, the funnel lid has multiple, evenly distributed, perforations.

[0012] Furthermore, the water-pumping airbag is a one-way airbag structure.

[0013] Furthermore, the hose also has a second section, one end of which is connected to the second end of the water-drawing airbag, and the other end of which is a free end.

[0014] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0015] 1. The structure is simple, and the filter media is degreased cotton, which is cheap, readily available, and easy to replace.

[0016] 2. Easy to operate, with a built-in water-pumping airbag and convenient siphon function.

[0017] 3. Replacing the filter media with other materials can achieve different filtration effects.

[0018] 4. The funnel is fixed with a funnel cover, so the filter media will not detach during use. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Figure 1 This is a schematic diagram of a preferred embodiment of a siphon-type seawater filtration device.

[0021] Figure 2 This is a schematic diagram showing the fit between the funnel and the funnel lid.

[0022] In the diagram, 1-funnel, 2-soft hose, 3-pumping airbag, 4-funnel cap, 41-cap hole Detailed Implementation

[0023] Please refer to Figure 1 A siphon-type seawater filtration device includes a funnel 1, a flexible hose 2, a pumping air bladder 3, and a funnel cover 4. Filter media, preferably degreased cotton, is placed inside the funnel. After the degreased cotton is inserted into the funnel, it is compressed and then sealed tightly with the funnel cover 4, which has a cover hole 41. A fixing structure is provided between the funnel cover 4 and the funnel. The fixing structure is preferably a snap-fit ​​fixation. Alternatively, a clamp, such as a clip, can be used for clamping.

[0024] The funnel lid 4 has multiple, evenly distributed, cap holes 41. In this embodiment, there are seven cap holes: one in the center and the remaining six evenly spaced around it. Figure 2As shown, the funnel cover 4 is slightly larger than the funnel. The bottom of the funnel cover 4 is flat, and the sidewalls are shaped to fit the sidewalls of the funnel. The funnel cover 4 and the funnel 1 can also be fixed by threads, that is, the outer surface of the funnel cover 4 has external threads near the upper end, and the inner surface of the funnel has internal threads near the upper end, and the external threads and internal threads are fitted together for fixation.

[0025] The water-absorbing airbag 3 is mounted on the hose 2. The water-absorbing airbag 3 is preferably a one-way airbag structure.

[0026] The hose has two sections. One end of the first section is connected to the bottom of the funnel, and the other end is connected to the upper end of the water-drawing airbag. One end of the second section is connected to the lower end of the water-drawing airbag, and the other end of the second section is a free end.

[0027] The uses of this utility model are as follows:

[0028] After filling the funnel with absorbent cotton, press it down firmly, and then cover it tightly with the funnel lid 4 through the lid hole 41. The clips secure the funnel lid 4 to the funnel.

[0029] Then submerge the funnel into the seawater bucket. Squeeze the pump bladder 3 to allow water to enter the plastic hose 2. The seawater is then siphoned through the absorbent cotton and flows naturally into the collection bucket below. The absorbent cotton can be replaced after a period of use when its filtration effect deteriorates.

[0030] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
