[0002] Biochemical felt is a widely used filter material that primarily provides biochemical filtration and is suitable for use in marine, freshwater, and planted aquariums. It can cultivate beneficial bacteria, improve water quality, and increase fish survival rates.

[0003] Reference patent application number 201420720344.5 Chinese utility model patent discloses a biochemical felt with particles, which is composed of a plurality of interlaced strip filaments, and the strip filaments are coiled to form a three-dimensional structure with countless micropores. A plurality of small particles are provided on the surface and / or inside of the strip filaments. Each strip filament of this structure has many small particles on the surface or inside. These small particles greatly increase the surface area of ​​the strip filaments, increase the area where beneficial bacteria can adhere, and effectively increase the number of beneficial bacteria.

[0004] However, it was found during use that when multiple pieces of biochemical felt were used side by side, the resistance of the biochemical felt structure to water flow was too great and the permeability was not ideal. Therefore, water flowed through the biochemical felt slowly. It was often necessary to space the biochemical felts so that water could pass through the gaps to increase the water flow rate. However, this required the use of other components to fix the multiple spaced biochemical felts, which was more troublesome to use. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a biochemical felt for water circulation filtration.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A biochemical felt for water circulation filtration, comprising a plurality of interlaced strip-shaped filaments, the plurality of said strip-shaped filaments being coiled around each other to form a water-permeable three-dimensional structure. A plurality of structural grooves are provided on one side of the biochemical felt, the plurality of said structural grooves being arranged in sequence and extending along the length or width of the biochemical felt. Multiple pieces of said biochemical felt are arranged in sequence to form a filtration assembly, and a plurality of through holes for rapid water flow are formed between adjacent pieces of said biochemical felt through the structural grooves.

[0008] The strip-shaped filaments are of a spiral structure, and the strip-shaped filaments of the spiral structure form a plurality of spiral knots along the length direction.

[0009] In the present invention, the structural groove is an arc-shaped structure, and an arc-shaped structural protrusion is formed between two adjacent structural grooves. Multiple structural protrusions and structural grooves form a wavy surface on the side of the biochemical felt. In the filter assembly, the wavy surface on one side of the biochemical felt is sequentially against the plane on the other side of the previous biochemical felt.

[0010] In the utility model, in the filter assembly, the planes of at least two adjacent biochemical felts are arranged opposite to each other, and the remaining biochemical felts are in contact with the plane of the upper biochemical felt through the wave surface.

[0011] In the utility model, in the filter assembly, the wave surfaces of at least two adjacent biochemical felts are arranged opposite to each other, and the structural protrusions on the two biochemical felts are relatively abutted, and the two opposite structural grooves form the through hole.

[0012] In the utility model, in the filter assembly, the wave surfaces of at least two adjacent biochemical felts are arranged opposite to each other, and the structural protrusion on one of the two biochemical felts is pressed against the structural groove on the other biochemical felt to form a seal.

[0013] In this embodiment, a baffle is provided on one side of the biochemical felt upper plane, and the baffle covers one side of the biochemical felt plane. In the filter assembly, multiple parallel filter channels are formed between multiple baffles.

[0014] The utility model has the following advantages and beneficial effects:

[0015] Multiple pieces of biochemical felt are arranged in sequence to form a filter assembly, and several through holes for water to pass quickly are formed between two adjacent pieces of biochemical felt through structural grooves. When water encounters resistance when flowing through the filter assembly, part of the water can flow quickly through the through holes and reach the next set of filter assemblies for filtration. Therefore, the through holes formed by the structural grooves can not only improve the permeability of the filter assembly, but also improve the filtration efficiency, making the water circulation smoother. In addition, by setting structural grooves on the side of the biochemical felt, through holes can be directly formed when two pieces of biochemical felt are placed side by side, without the need to use other components to separate them, thereby improving the convenience of use.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention, but the present invention is not limited to the following embodiments.

[0025] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0026] In addition, if there are descriptions involving "first" or "second" in the embodiments of the present invention, the descriptions of "first" or "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] like Figures 1 to 3As shown, this embodiment discloses a biochemical felt for water circulation filtration, comprising a plurality of interlaced strip filaments 1, wherein the plurality of strip filaments 1 are coiled together to form a three-dimensional structure with a certain water permeability, wherein the three-dimensional structure can be a cylinder, a cube or other irregular body, and the present embodiment is preferably a cube with a plate-like structure, wherein one side of the biochemical felt is provided with a plurality of structural grooves 2, and the grooves can be processed on one side of the biochemical felt by cutting, wherein the plurality of structural grooves 2 are arranged in sequence and extend along the length direction or width direction of the biochemical felt, and a plurality of the biochemical felts are arranged in sequence to form a process. The filter assembly 10, a number of through holes 3 for rapid water flow are formed between two adjacent biochemical felts through structural grooves 2. When water encounters resistance when flowing through the filter assembly 10, part of the water flow can quickly flow through the through holes 3 and reach the next group of filter assemblies 10 for filtration. Therefore, the through holes 3 formed by the structural grooves 2 can not only improve the permeability of the filter assembly 10, but also improve the filtration efficiency, making the water circulation smoother. In addition, by arranging the structural grooves 2 on the side of the biochemical felt, the through holes 3 can be directly formed when the two biochemical felts are side by side, without the need to use other components to separate them, thereby improving the convenience of use.

[0028] In this embodiment, Figure 6 and Figure 7 As shown, in order to improve the adhesion of the biochemical felt to the bacterial flora and filtered materials, the strip filament 1 is designed to be a spiral structure, and the strip filament 1 with a spiral structure forms a plurality of spiral knots 100 along the length direction; or the strip filament 1 is designed to be composed of a plurality of wire segments 101 of different lengths connected in sequence irregularly, and the surface roughness of the strip filament 1 is increased by the spiral knots 100 or the wire segments 101, so that the bacterial flora and filtered materials are effectively attached to the strip filament 1, thereby improving the filtration and purification efficiency of the biochemical felt.

[0029] In this embodiment, the structural groove 2 is an arc-shaped structure, and an arc-shaped structural protrusion 4 is formed between two adjacent structural grooves 2. Multiple structural protrusions 4 and structural grooves 2 form a wavy surface on the side of the biochemical felt. In the same filter component 10, the wavy surface on one side of the biochemical felt is successively against the plane on the other side of the previous biochemical felt. Therefore, setting the structural groove 2 and the structural protrusion 4 to an arc shape can not only improve the aesthetics of the biochemical felt, but also the formed wavy surface can form a through hole 3 with uniform shape and size against the plane, so that water can flow evenly through the filter component 10.

[0030] Not limited to the above embodiments, Figure 4 As shown, in the same filter assembly 10, the planes of at least two adjacent biochemical felts can be abutted against each other, and the remaining biochemical felts can be abutted against the plane of the previous biochemical felt through the wavy surface, thereby changing the number of through holes 3 and thus changing the permeability of the filter assembly 10.

[0031] Not only that, if Figure 5 As shown, in the same filter assembly 10, the wavy surfaces of two adjacent biochemical felts can also be abutted against each other, specifically, the structural protrusions 4 on the two biochemical felts are relatively abutted, and the relative structural grooves 2 form the larger through-hole 3, or the structural protrusion 4 on one of the biochemical felts is abutted against the structural groove 2 on the other biochemical felt to form a closure. By combining multiple biochemical felts in different ways, filter assemblies 10 with different structures and different numbers of through-holes 3 can be formed, so that different filter assemblies 10 can be applied according to the water flow rate, thereby improving practicality and reducing costs.

[0032] In this embodiment, in order to allow water to flow along the cross-sectional direction of the biochemical felt, a baffle 5 can be set on one side of the upper plane of the biochemical felt. The baffle 5 covers one side of the biochemical felt plane to prevent water from flowing into the biochemical felt from the side. In the filter assembly 10, after multiple pieces of the biochemical felt are arranged in sequence, multiple parallel filtration channels are formed through the baffle 5, which can improve the purification effect and purification efficiency of the water to a certain extent.

[0033] The above contents described in this specification are merely examples of the present invention. Those skilled in the art in the technical field to which the present invention belongs may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the contents of the present invention specification or exceed the scope defined by the claims, they shall fall within the scope of protection of the present invention.
