Description

Technical Field

[0001] This utility model belongs to the field of aquarium filtration technology, specifically relating to a device for separating and settling fish waste and impurities in live water. Background Technology

[0002] Traditional aquarium bottom filtration systems rely on filter cotton to intercept impurities, which has three major drawbacks: filter cotton is prone to clogging and requires frequent cleaning; water flow disturbance in the sedimentation tank causes dirt to float a second time; and impurities accumulate at the bottom of the clear water tank, forming a stagnant water zone. Existing improvement solutions (such as adding a physical filtration layer) can improve the coarse filtration effect, but they cannot solve the problem of dirt accumulation at the bottom of the clear water tank, leading to a decrease in filtration efficiency and the risk of water quality deterioration. Utility Model Content

[0003] The present invention aims to provide a device for separating and settling fish waste and impurities in live water, which solves the technical problem that existing aquarium bottom filtration systems cannot solve the problem of reduced filtration efficiency caused by the accumulation of dirt at the bottom of the clear water tank.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A device for separating and settling fish waste in live water, comprising:

[0006] Bottom filter cylinder;

[0007] A double anti-water baffle is installed inside the bottom filter cylinder, dividing the inner cavity of the bottom filter cylinder into a clear water chamber and a sedimentation chamber.

[0008] The filter screen is located in the clear water tank. Its inlet end is equipped with a union joint, and its outlet end is connected to the double anti-water baffle.

[0009] The clean water drain outlet is located at the top of the clean water tank and is used to connect the dry and wet separation box.

[0010] The wastewater discharge outlet is located at the bottom of the sedimentation tank and is equipped with a forced discharge pipe fitting;

[0011] The double anti-water baffle includes a baffle plate and an overflow plate arranged in parallel, with a gap between the baffle plate and the overflow plate. There is a gap between the bottom of the baffle plate and the bottom of the bottom filter cylinder. The bottom and both sides of the overflow plate are sealed and bonded to the bottom and inner wall of the bottom filter cylinder. The baffle plate is located on the clear water tank side, and the overflow plate is located on the sedimentation tank side.

[0012] Furthermore, the overflow plate and the baffle plate are equipped with water outlet pipe joints, and the water outlet end of the filter screen is connected to the water outlet pipe joint.

[0013] Furthermore, the inlet end of the filter screen is higher than the outlet end.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model intercepts fish waste and discharges it directly into the sedimentation tank through the inclined filter screen, which significantly reduces the frequency of filter cotton clogging; the dynamic sewage discharge mechanism based on water pressure difference established by the double anti-water baffle forces the sediment at the bottom of the clear water tank to migrate directionally to the sedimentation tank, completely eliminating the dead water zone; combined with the static enrichment of the sedimentation tank and the centralized sewage discharge of the strong discharge pipe, it achieves efficient separation of fish waste and impurities without manual cleaning throughout the process, while ensuring water quality stability. Attached Figure Description

[0015] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:

[0016] Figure 1 This is a schematic diagram of the structure of a live water fish excrement impurity separation and sedimentation device according to the present invention. Detailed Implementation

[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] The present invention will be further described in detail below with reference to the embodiments.

[0019] like Figure 1 As shown, here is a specific embodiment 1 of the live water fish waste impurity separation and sedimentation device provided by this utility model:

[0020] A live-water fish waste separation and sedimentation device includes a bottom filter tank 1. A double-reverse-flow baffle is installed inside the bottom filter tank 1, dividing the inner cavity of the bottom filter tank 1 into a clear water chamber 2 and a sedimentation chamber 3. A filter screen 4 is installed inside the clear water chamber 2. A union connector 5 is installed at the inlet end of the filter screen 4, and the outlet end of the filter screen 4 is connected to the double-reverse-flow baffle. A clear water drain outlet 6 is provided at the top of the clear water chamber 2 for connecting to a dry-wet separation box. A wastewater discharge outlet 7 is provided at the bottom of the sedimentation chamber 3 for installing a forced-flow pipe fitting.

[0021] The double anti-water baffle includes a baffle plate 8 and an overflow plate 9 arranged in parallel, with a 1.5cm-2cm gap between the two plates. There is a gap between the bottom of the baffle plate 8 and the bottom of the bottom filter tank 1. The bottom and both sides of the overflow plate 9 are sealed and bonded to the bottom and inner wall of the bottom filter tank 1. The baffle plate 8 is located on one side of the clear water tank 2, and the overflow plate 9 is located on one side of the sedimentation tank 3.

[0022] To facilitate the discharge of waste, the filter screen 4 is set at an angle, with its inlet end higher than its outlet end.

[0023] Because dirt can easily accumulate inside the filter tube 4 after long-term use, it can be designed as a detachable structure: the overflow plate 9 and the baffle plate 8 are equipped with water outlet pipe joints 10, and the water outlet end of the filter tube 4 is connected to the water outlet pipe joints 10.

[0024] The separation and precipitation process of this device is carried out according to the following steps:

[0025] Wastewater in aquarium 100 is piped to the inlet of filter pipe 4. As the water flows through filter pipe 4, its internal mesh structure intercepts fish waste and coarse particles. The trapped solids, under the impact of the water flow, are discharged with some water from the outlet of filter pipe 4 into sedimentation chamber 3. The water, after initial filtration by filter pipe 4, flows into clear water chamber 2. Residual micro-suspended matter in clear water chamber 2 settles to the bottom under gravity. Simultaneously, the clarified water in the upper part of clear water chamber 2 is transported through clear water drain outlet 6 to the wet-dry separation box for secondary treatment before finally returning to the aquarium. It should be noted that the wet-dry separation box is a conventional technology, and since it is not a core component of this technical solution, its specific structure will not be described in detail.

[0026] When the water level in the clear water tank 2 continues to rise to a height exceeding the top of the overflow plate 9, a water level pressure difference is formed between the clear water tank 2 and the sedimentation tank 3. This pressure forces the bottom water of the clear water tank 2 to carry the settled dirt and enter the gap between the baffle plate 8 and the overflow plate 9 through the gap at the bottom of the baffle plate 8, and then roll upwards over the top of the overflow plate 9 and flow into the sedimentation tank 3, finally removing the fish feces and impurities accumulated at the bottom of the clear water tank 2.

[0027] Wastewater entering sedimentation tank 3 (including fish excrement, coarse particles, and sludge discharged from clear water tank 2) undergoes final sedimentation in a static environment, with sludge accumulating at the bottom of sedimentation tank 3. The accumulated sludge is discharged from the system through the forced discharge pipe 7 connected to the wastewater outlet, completing the entire impurity separation process.

[0028] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
