Description

Technical Field

[0001] This utility model relates to the field of filter technology, and more specifically, to a biomimetic filter. Background Technology

[0002] A filter screen is a mesh tool with evenly distributed pores. Its main function is to classify, screen, filter, or reinforce particles according to their size. Simply put, a filter screen acts like a "classifier," allowing particles smaller than the mesh openings to pass through while retaining particles larger than the mesh openings, thus achieving the purpose of separating particles by size.

[0003] Traditional filter screens have straight, smooth pores. In mixed liquids with high flow rates and strong agitation, the filter material easily moves up and down within the pores, failing to achieve unidirectional filtration and resulting in ineffective filtration. Furthermore, during vibrating screening, materials with a similar diameter to the pores can become stuck in the pores. Due to vibration, the material moves up and down within the screen, preventing it from exiting. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a biomimetic filter screen for unidirectional filtration of materials and to prevent clogging.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A biomimetic filter includes a filter body and a plurality of filter holes disposed on the filter body. The inner wall of the filter holes is provided with unidirectional scales arranged in a fish-scale pattern from top to bottom, and the unidirectional scales are inclined downward.

[0007] Compared with the prior art, the present invention has at least the following beneficial effects: The inner wall of the filter holes is equipped with one-way scales, which guide the material downwards in one direction, so that the material can only be filtered and screened in one direction and will not flow back from the filter holes. During vibrating screening, the material can only move downwards in one direction, so the material will not move up and down and get stuck in the filter holes, thus reducing the clogging rate.

[0008] In some embodiments, the unidirectional scale is made of a rigid material, and the aperture at the top of the filter pore is equal to or slightly smaller than the inner diameter of the unidirectional scale.

[0009] In some embodiments, the unidirectional scale is a brush, and the pore diameter of the filter is equal to or greater than the inner diameter of the unidirectional scale.

[0010] In some embodiments, a retaining ring is embedded in the filter pore, and the unidirectional scale is disposed on the inner wall of the retaining ring.

[0011] In some embodiments, the filter body is provided with several filtration zones, and the unidirectional scales of the several filtration zones gradually decrease in downward tilt angle.

[0012] In some embodiments, the pore size of the filter pores in the plurality of filter zones gradually decreases.

[0013] In some embodiments, the filter body is corrugated.

[0014] In some embodiments, the filter pores are inverted conical in shape. Attached Figure Description

[0017] 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.

[0018] refer to Figure 1-2 A biomimetic filter includes a filter body 1 and a plurality of filter holes 2 disposed on the filter body 1. The inner wall of the filter holes 2 is provided with unidirectional scales 3 arranged in a fish scale pattern from top to bottom, and the unidirectional scales are inclined downward.

[0019] Understandably, the filter body 1 can be a flat plate structure such as stainless steel or plastic, or a frame structure, but is not limited to these. The unidirectional scales 3 can be a ring structure, stacked from top to bottom; or they can be multiple scales arranged in a ring shape and then stacked from top to bottom, etc., but are not limited to these. Here, the unidirectional scales 3 can not only be a rigid material integrated with the filter body 1, but also a soft material similar to a brush.

[0020] With this configuration, the inner wall of the filter hole 2 is equipped with one-way scales 3. The one-way scales 3 have a downward one-way guiding effect on the material, so that the material can only be filtered and screened in one direction and will not flow back from the filter hole 2. During vibrating screening, the material can only move downward in one direction, so the material will not move up and down and get stuck in the filter hole 2, thus reducing the clogging rate.

[0021] Optionally, in some embodiments, reference is made to Figure 2-4 The unidirectional scale 3 is made of hard material, and the pore diameter at the top of the filter hole 2 is equal to or slightly smaller than the inner diameter of the unidirectional scale.

[0022] Understandably, the rigid unidirectional scales 3 can be integrally formed with the filter body 1, such as stainless steel or plastic, but are not limited to these. Of course, the unidirectional scales 3 can also be made in a ring shape and installed in the filter holes 2 in an embedded and fixed manner.

[0023] With this configuration, materials larger than the top aperture of filter hole 2 will not enter filter hole 2, and naturally will not enter the one-way scale 3, thus avoiding jamming.

[0024] Optionally, in some embodiments, reference is made to Figure 5 The unidirectional scale 3 is a brush, and the aperture of the filter hole 2 is equal to or greater than the inner diameter of the unidirectional scale 3. In this way, the brush can deform. After the material enters the filter hole 2, it can move downward along the inclined direction of the brush. If the material moves upward, the brush will hold the material in place to prevent it from moving upward.

[0025] Optionally, in some embodiments, reference is made to Figure 5 A retaining ring 5 is embedded inside the filter hole 2, and a one-way scale 3 is set on the inner wall of the retaining ring 5. Here, if the one-way scale 3 is made of a brush, it is not convenient to integrally form it with the filter hole 2. The retaining ring 5 with the brush is prefabricated and then reinforced and fixed by snapping or using glue.

[0026] Optionally, in some embodiments, reference is made to Figure 1 The filter body 1 is divided into several filter zones 4, for reference. Figure 2-4 The unidirectional scales 3 of several filter zones 4 tend to slope downwards at progressively smaller angles.

[0027] Understandably, the filter zone 4 can be set on a single filter body 1, or it can be set on multiple continuously connected filter screens. The unidirectional scales 3 of each filter zone 4 have the same tilt angle, but the unidirectional scales 3 of different filter zones 4 have different tilt angles.

[0028] With this configuration, when the filter screen acts as a sieving element, a gentler inclination angle of the unidirectional scale 3 results in stronger unidirectional filtration resistance, allowing it to handle finer materials. Conversely, a more downward inclination angle of the unidirectional scale 3 results in weaker filtration resistance, allowing it to handle larger materials, thus achieving graded sieving.

[0029] Optionally, in some embodiments, the pore size 2 of the filter zones 4 gradually decreases. Similarly, materials of different sizes can also be graded and screened.

[0030] Optionally, in some embodiments, reference is made to Figure 1 The filter body 1 is corrugated. This increases the filtration and sieving area and also strengthens the structural strength of the filter.

[0031] Optionally, in some embodiments, reference is made to Figure 6 The filter holes 2 are inverted cone shapes. Here, the inverted cone-shaped filter holes 2 have a small inlet and a large outlet, eliminating the possibility of "critical material" getting stuck at the inlet from the source. Once the material passes through the narrow inlet and enters the gradually expanding internal space, it has enough room to pass smoothly, making it almost impossible to cause blockage inside. Combined with the one-way scale 3, it can also effectively prevent the possibility of material entering through the top from the bottom opening of the filter holes 2.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
