[0001] This application relates to the field of aquarium fish waste separation technology, and in particular to an aquarium solid-liquid separation device and an aquarium. Background Technology

[0002] Currently, aquariums generally face problems such as low efficiency in separating solid pollutants (such as fish waste and food scraps), large size of separation equipment, need for manual drainage, and large drainage volumes.

Summary of the Invention

Detailed Implementation

[0034] In the following description, numerous details are provided to enable a thorough understanding of this application. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the application, and that the application can be implemented without one or more of these details. Furthermore, to avoid confusion with this application, some technical features well-known in the art have not been described in detail.

[0035] According to one aspect of this application, referring to Figures 1 to 15, an aquarium solid-liquid separation device is provided. The aquarium solid-liquid separation device includes: an energy-dissipating chamber 1, a water inlet channel 2, a settling chamber 3, and a water inlet 7. The water inlet 7 is located at the lower end of the water inlet channel 2 and is connected to the water inlet channel 2. The energy-dissipating chamber 1 is located above the water inlet channel 2 and the settling chamber 3, and is connected to both the water inlet channel 2 and the settling chamber 3. The flow area of ​​the water inlet channel 2 is smaller than the flow area of ​​the energy-dissipating chamber 1. The water inlet channel 2 is connected to the energy-dissipating chamber 1, and the energy-dissipating chamber 1 is used to receive water flow from the water inlet channel 2 and reduce the water flow velocity. The energy dissipation chamber 1 is located above and connected to the settling chamber 3. Specifically, the inlet 7 is located at the bottom of the aquarium to absorb solid pollutants (such as fish waste and food scraps) from the bottom. The inlet 7 is connected to the inlet channel 2. As is well known, solid pollutants settle at the bottom of the aquarium and move with the water flow. Therefore, the inlet 7 can be designed as a long, narrow opening structure, which facilitates a longer pollutant collection path and a matching water flow speed within the same flow area, thereby improving the collection efficiency of solid pollutants in the aquarium. The water flow carrying solid pollutants is sucked in by the inlet 7 and enters the energy dissipation chamber 1 through the inlet channel 2. In practical applications, the flow area of ​​the inlet channel can be adjusted according to the type of solid pollutants. The circulating water flow rate is set so that the water flow in the inlet channel 2 can carry solid pollutants from bottom to top into the energy dissipation chamber 1. When the water flows into the energy dissipation chamber 1 from the inlet channel 2, the flow velocity drops sharply due to the increase in the volume of the chamber, and the kinetic energy of the water decreases rapidly. The solid pollutants carried in the water settle into the settling chamber 3 due to gravity. The water flows through the energy dissipation chamber 1 and flows out from the top of the energy dissipation chamber 1, realizing solid-liquid separation. The settling chamber 3 is set into an inverted cone structure, which facilitates the accumulation of solid pollutants towards the center and sinks to the bottom of the chamber, reducing the dead corners of sediment retention. As shown in Figures 4, 13 and 15, the bottom of the settling chamber 3 is provided with a drain outlet 9, which is used to preferentially discharge the accumulated solid pollutants, thereby reducing the amount of water consumed.

[0036] In some embodiments, as shown in Figures 3, 4, and 10, the inlet channel 2 is used to allow water to flow laterally into the energy dissipation chamber 1, enabling the water to diffuse horizontally within the chamber 1 to form a uniform flow field, reduce the generation of eddies, decrease the interference of turbulence on the sedimentation process, and reduce the upward component of solid pollutants, resulting in more stable sedimentation and further improving solid-liquid separation efficiency. For example, as shown in Figures 3 and 10, the stability of particle sedimentation can be improved by setting the outlet of the inlet channel 2 to a horizontal outlet, or by setting a guide plate 15 above the outlet of the inlet channel 2 as shown in Figure 4.

[0037] In some embodiments, as shown in Figures 1 to 15, the aquarium solid-liquid separation device further includes a flow equalization component 13. The flow equalization component 13 is disposed above the energy dissipation chamber 1. The flow equalization component 13 is used to disperse the water flow above the energy dissipation chamber 1, so that the water flow is uniformly flowing out from the upper region of the energy dissipation chamber 1, thereby promoting uniform water flow in the upper part of the energy dissipation chamber 1 and avoiding excessively fast local flow velocity that would cause solid pollutants to be carried upward out of the energy dissipation chamber 1, thereby improving the stability and efficiency of solid-liquid separation. As shown in Figures 3, 6, and 9, the flow equalization component 13 has a porous structure and can be composed of porous materials (such as porous filter cotton, porous foamed materials, etc.) or can be composed of granular materials (such as quartz sand, ceramic particles, plastic fillers, foamed particles, etc.). The above is only an exemplary description of the flow equalization component and is not a limitation of this application. In practical applications, its porosity and pore size can be adapted to the particle size of the solid suspended matter in the aquarium to achieve the best water flow distribution and particle interception effect. The pore density or size can also be adjusted according to the required water flow rate to precisely control the water flow uniformity, water flow rate and interception efficiency in the upper part of the energy dissipation chamber 1, and to adapt to the solid-liquid separation requirements under different working conditions. The introduction of the flow equalization component significantly reduces the vertical velocity component of the water flow, effectively preventing solid pollutants from failing to settle or being re-stirred due to water flow disturbance, while also enhancing overall hydraulic stability. The porous structure of the flow equalization component achieves uniform water flow distribution and, through the synergistic effect of surface interception and internal filtration, traps fine suspended particles. Simultaneously, the porous material can be used for biological cultivation to treat harmful substances in the water flow, achieving the dual functions of water flow dispersion and biological filtration. The modular design of the flow equalization component 13 facilitates disassembly and cleaning, effectively addressing the risk of clogging during long-term operation and maintaining the efficient and continuous operation of the aquarium's solid-liquid separation device.

[0038] In some embodiments, as shown in Figures 1, 8, and 15, the flow equalization component 13 can also be a porous tube structure, such as a honeycomb panel, a tapered aperture tube, or an inclined aperture tube. For example, the honeycomb panel is composed of regular hexagonal units, which can efficiently disperse the water flow. The regular channels of the honeycomb panel can effectively reduce the shear force of the water flow, making the flow field distribution more uniform and avoiding interference of local turbulence on the sedimentation process. The tapered aperture tube gradually adjusts the aperture size along the flow direction to achieve a synergistic effect of high flux in the inflow area and fine filtration in the outflow area, further optimizing the balance between water flow transition and particle retention. The inclined aperture tube design allows the water flow above the energy dissipation chamber to enter the inclined aperture tube in an inclined direction, effectively reducing the vertical velocity component and promoting the sedimentation of solid particles. Of course, the above are only exemplary and are not limitations of this application.

[0039] In some embodiments, as shown in Figures 8 and 13, the flow equalization component 13 includes at least two flow equalization sections. The aperture size of the flow equalization component 13 gradually decreases from the first flow equalization section 131 to the Nth flow equalization section 132, causing the front and rear regions of the energy dissipation chamber 1 to generate a decreasing upward force of water flow, thereby optimizing the distribution of water flow and solid pollutants, and thus improving the influent flow rate and solid pollutant settling efficiency. Specifically, when water flows into the energy dissipation chamber 1 from the influent channel 2, it first passes through the front region of the energy dissipation chamber 1 corresponding to the first flow equalization section 131. The larger aperture of the first flow equalization section 131 allows for a higher water flow rate and generates a larger upward water flow in the lower region. Due to inertia, solid pollutants can overcome the upward force of the water flow in this region and pass through quickly, preventing solid pollutants from entering the first flow equalization section 131 from this region and affecting the separation efficiency. The larger aperture of the first flow equalization section 131 allows for a higher water flow rate, which significantly weakens the water flow velocity and reduces the flow velocity in other areas. When the water flows into the area corresponding to the Nth flow equalization section 132, the water flow velocity is greatly reduced. The smaller the upward force of the water flow acting on the solid pollutants, the better the settling effect in the area above the settling chamber 3 at the end of the energy dissipation chamber. Therefore, through the multi-aperture configuration of multiple flow equalization sections of the flow equalization component 13, the treatment flow rate and settling efficiency are significantly improved.

[0040] In some embodiments, the flow equalization component can be configured with a gradually decreasing orifice size along the water inlet direction. The gradually decreasing orifice size design allows the flow equalization component in the front end region of the energy dissipation chamber to have a larger orifice size, allowing for a higher water flow rate. The front end region of the energy dissipation chamber generates a larger upward water flow, and solid pollutants, due to water flow and inertia, can overcome the upward force of the water flow in this region and pass through quickly. The front end region of the energy dissipation chamber significantly weakens the water flow velocity, reducing the flow velocity in other regions. Therefore, through the gradually decreasing orifice size distribution of the flow equalization component, the front and rear regions of the energy dissipation chamber 1 generate a decreasing upward force of water flow, thereby optimizing the distribution of water flow and solid pollutants, and thus improving the inlet flow rate and solid pollutant settling efficiency.

[0041] In some embodiments, as shown in Figures 3, 9, and 13, a flow-blocking section 12 is provided at the upper part of the settling chamber 3 to block the turbulence transmission caused by the continuous water flow, thereby reducing the disturbance intensity of the water flow in the energy dissipation chamber 1 on the water flow in the settling chamber 3. The flow-blocking section 12, through structures such as baffles, guide fins, or irregular protrusions, disrupts the direction of the water flow rising along the wall of the settling chamber 3, preventing suspended solid pollutants from being carried out of the settling chamber 3 by the water flow; and disrupts the water flow pattern during the transition from the energy dissipation chamber 1 to the settling chamber 3, effectively blocking the turbulence transmission caused by the continuous water flow, avoiding the instability of the flow field in the settling zone, and preventing light or small solid pollutants from being resuspended or carried out of the settling chamber 3 by the water flow, thus ensuring the continuity and efficiency of the settling process. For example, the upper surface of the flow-blocking part 12 is flush with the bottom of the energy-dissipating chamber 1, so that a cross-section is formed between the energy-dissipating chamber 1 and the settling chamber 3. This allows the water flow rising along the wall of the settling chamber 3 to be blocked by the flow-blocking part 12, preventing the formation of a continuous rotating water flow that carries the settling solids. By maintaining a stable low flow velocity inside the settling chamber 3, the settling efficiency of solid particles is further improved, while preventing the already settling solid particles from being carried away by the water flow again, thereby ensuring the stability and high efficiency of solid-liquid separation. Alternatively, the flow-blocking part 12 can also be provided on at least one wall surface or all walls of the settling chamber 3. Of course, the above are merely examples and are not intended to limit the scope of this application.

[0042] In some embodiments, as shown in Figures 1 to 8, the water inlet channel 2 and the settling chamber 3 are arranged side by side. In practical applications, the sum of the flow area of ​​the water inlet channel 2 and the flow area of ​​the upper part of the settling chamber 3 is approximately equal to the flow area of ​​the energy dissipation chamber 1, and the width of the water inlet channel 2 is approximately equal to the width of the energy dissipation chamber 1. Furthermore, the flow area of ​​the water inlet is ≤30% of the flow area of ​​the water inlet channel and ≤30% of the flow area of ​​the energy dissipation chamber; thus, the aquarium solid-liquid separation device has a compact structure. For example, the flow area of ​​the water inlet channel 2 is set to be less than or equal to 30% of the flow area of ​​the energy dissipation chamber 1. For instance, the flow area of ​​the water inlet channel 2 can be set to 5%, 10%, or 15% of the flow area of ​​the energy dissipation chamber 1. 20%, 25%, or 30% are used to ensure that solid pollutants flow upward through the inlet channel 2 and into the energy dissipation chamber 1, and that the flow velocity decreases significantly after entering the energy dissipation chamber 1, thereby improving the settling efficiency of solid particles. Of course, the above is only an example and is not a limitation of this application. Furthermore, the flow area of ​​the inlet is smaller than that of the inlet channel. When the water carries solid pollutants from the inlet into the inlet channel, the flow area suddenly expands, the water velocity decreases, and the velocity and kinetic energy of the solid pollutants also decrease. When the water velocity in the energy dissipation chamber decreases further, the kinetic energy of the solid pollutants also decreases further, so that they can settle more stably in the settling chamber.

[0043] In some implementations, the flow area at the inlet end of the water inlet channel is smaller than the flow area at the outlet end 16 of the water inlet channel, as shown in Figure 5. This gradual expansion design helps to reduce the velocity gradient of the water flow in the water inlet channel, making the water flow at the outlet end 16 of the water inlet channel more stable, improving the uniformity of the flow field in the energy dissipation chamber 1, and thus further improving the settling efficiency of solid particles.

[0044] In some embodiments, as shown in Figures 9 to 15, the energy dissipation chamber 1 is configured with a transverse structure, and the flow equalization component 13 is disposed above the energy dissipation chamber 1 to adjust the speed and direction of the water flow and reduce the disturbance of the water flow. The water flow enters the water inlet channel 2 from the water inlet 7 and flows into the energy dissipation chamber 1 from the water outlet 16 of the water inlet channel. Specifically, the energy dissipation chamber 1 adopts a transversely extending chamber structure, thereby increasing the flow path of the water flow in the energy dissipation chamber 1 and the water passage area of ​​the flow equalization component 13, thereby dispersing the upward flow velocity of the water flow per unit area, weakening the upward thrust of the water flow carrying solid pollutants, and from the front end to the end end of the energy dissipation chamber 1... The water flow velocity gradually slows down, creating a low-velocity zone at the end of energy dissipation chamber 1 to reduce turbulence intensity. Settling chamber 3 is located at the end of energy dissipation chamber 1 and connected to its bottom. Because settling chamber 3 at the end of energy dissipation chamber 1 is a downward-extending cavity, the kinetic energy of the water flowing into it is further attenuated, allowing solid pollutants to settle stably under gravity. Explained, larger solid pollutants in energy dissipation chamber 1, due to their greater weight, first fall to the bottom of energy dissipation chamber 1. Driven by the continuously flowing water, they are gradually moved to the top of settling chamber 3 at the end of energy dissipation chamber 1 and settle into it under gravity. Smaller solid pollutants... Due to the lateral extension of the energy dissipation chamber 1, solid pollutants flow with the water within it. When they reach the settling chamber 3, the length of the energy dissipation chamber 1 and the flow equalization component 13 disperse the water flow intensity, reducing water flow disturbance within the settling chamber 3. When the weight of the solid pollutants exceeds the buoyancy and the thrust of the water flow disturbance, the solid pollutants settle into the settling chamber 3, thus improving the settling effect for smaller solid pollutants. Furthermore, the water flow disturbance in the bottom region of the settling chamber 3 is even smaller, preventing the water flow from carrying the settled solid pollutants out of the settling chamber 3, thereby increasing the solid-liquid separation efficiency. The water flow generated by the lateral structural configuration of the energy dissipation chamber 1... The horizontal thrust pushes the solid pollutants settled at the bottom of the energy dissipation chamber 1 to the settling chamber 3, thereby reducing the inlet area of ​​the settling chamber 3, making the wall inclination angle of the settling chamber 3 larger, and the accumulation surface of solid pollutants at the bottom of the settling chamber 3 smaller. When discharging the deposited solid pollutants, the solid pollutants accumulated at the bottom of the settling chamber 3 can be discharged first, thereby greatly reducing the loss of clean water during the sewage discharge process. In addition, the horizontal structure configuration of the energy dissipation chamber 1 enables the horizontal water flow in the chamber to push the solid pollutants to the settling chamber 3, thereby greatly reducing the height of the energy dissipation chamber 1 and reducing the volume of the solid-liquid separation device of the aquarium.

[0045] In some embodiments, as shown in Figures 12, 14, and 15, the cross-section of the energy dissipation chamber can be configured as a V-shaped or U-shaped structure that gradually decreases from both sides to the middle. The V-shaped or U-shaped structure design prevents solid pollutants from being unable to be pushed to the settling chamber 3 due to the excessive length of the energy dissipation chamber or the low water flow velocity at the end of the energy dissipation chamber, resulting in local deposition in the energy dissipation chamber. Through the inclined sidewall design of the V-shaped or U-shaped structure, solid pollutants slide down to the bottom center area of ​​the energy dissipation chamber 1 under the combined action of gravity and water flow. When the water outlet 16 of the inlet channel is set to face the bottom center of the energy dissipation chamber, the solid pollutants sliding towards the center area can be pushed to the settling chamber 3 by the impact force of the water flow, thereby effectively avoiding the retention and deposition of solid pollutants in the energy dissipation chamber.

[0046] In some embodiments, as shown in Figures 1, 3, 6, 9, and 11, the aquarium solid-liquid separation device further includes a drain assembly 14, which is used to discharge solid sediments from the settling chamber 3. To promptly and automatically clean solid contaminants deposited at the bottom of the settling chamber 3, the drain assembly 14 can be installed inside the settling chamber 3, or connected to the bottom of the settling chamber 3, to prioritize the discharge of solid contaminants. The drain procedure can be initiated periodically or as needed to ensure that solid contaminants do not excessively accumulate at the bottom of the chamber. For example, the drain assembly 14 can be at least one of a water pump 141 or a valve. For instance, as shown in Figures 3 and 10, when the drain assembly 14 is a water pump 141, the water pump 141 can be installed inside the settling chamber 3 with its inlet 1411 facing the bottom of the settling chamber 3. The negative pressure generated by the operation of the water pump 141 draws the solid contaminants deposited at the bottom out of the settling chamber 3, achieving efficient draining and automated control, eliminating the need for manual draining. In addition, by setting the water pump inlet 1411 towards the bottom of the settling chamber 3, the water pump 141 and the settling chamber 3 can be separated into two areas, namely the upper settling area and the sedimentation area below the water pump 141. By obstructing the flow through the water pump 141 body, the sedimentation area below the water pump 141 forms a relatively still area of ​​water flow, which greatly reduces the disturbance of the water flow in the settling area to the solids in the sedimentation area, promotes the continuous accumulation of solid pollutants in the sedimentation area, and avoids the resuspension of settled particles. Of course, as shown in Figures 11 and 12, the water pump 141 can also be set outside the settling chamber 3, and the purpose of extracting sediment can be achieved by connecting the water pump inlet 1411 to the sewage outlet 9. In addition, as shown in Figures 4, 5, 8, 13, and 15, when the sewage discharge component 14 is an electrically controlled valve, the electrically controlled valve can be connected to the sewage discharge port 9 through a pipeline. By controlling the opening and closing of the valve, the deposited solid pollutants can be discharged on a timed or as-needed basis. The solid pollutants can be discharged by gravity under the action of water pressure and gravity when the electrically controlled valve is opened, thus achieving efficient and controllable sewage discharge.

[0047] In some embodiments, as shown in Figures 1, 3, 9, and 10, the aquarium solid-liquid separation device further includes an oil film removal port 21. The oil film removal port 21 is connected to the energy dissipation chamber 1 through a channel and is used to suck up the oil film on the water surface, as well as light suspended matter such as floating fish waste and uneaten food, so as to better remove organic pollutants in the aquarium. Water entering the oil film removal port 21 flows into the energy dissipation chamber 1, and the light suspended matter such as floating fish waste and uneaten food is intercepted by the flow equalization component 13 (such as filter cotton) made of porous material, so that the intercepted floating matter can be cleaned when cleaning the flow equalization component 13 later.

[0048] In some embodiments, as shown in Figures 6 and 7, the aquarium solid-liquid separation device further includes an oil film removal float 22. The oil film removal float 22 is used to automatically adjust with the rise and fall of the water level. The oil film removal float 22 is always close to the water surface by the buoyancy. The oil film and light pollutants on the surface of the water are guided into the oil film removal float under the action of water flow, and enter the energy dissipation chamber 1 through the water flow channel and are intercepted by the flow equalization component 13.

[0049] In some embodiments, as shown in Figures 6, 7, 12, 13, and 15, the upper part of the flow equalization component 13 of the aquarium solid-liquid separation device can be configured as a closed collection chamber 4. The collection chamber 4 is connected to the water outlet 8. The clean water filtered by the flow equalization component 13 flows into the collection chamber 4. The water outlet 8 can be connected to a water pump. The negative pressure generated by the water pump can solve the problem of poor water flow caused by water level difference, ensuring stable system operation. Furthermore, the water in the collection chamber 4 can be pumped out and transported to a subsequent treatment unit or directly returned to the aquarium as needed, achieving efficient recycling of clean water. As shown in Figures 6 and 7, the flow equalization component 13 can be configured as a drawer-type structure, which is convenient for disassembly, cleaning, or replacement. During cleaning, simply pull out the drawer to clean or replace the flow equalization component 13, greatly improving maintenance efficiency and convenience.

[0050] In some embodiments, as shown in FIG8, the aquarium solid-liquid separation device may include multiple settling chambers 3 arranged side by side. This allows the sidewalls of the settling chambers 3 to be angled more significantly when the energy dissipation chamber 1 is longer, preventing sediment from accumulating on the sidewalls and failing to slide smoothly to the bottom of the settling chamber 3. The angled sidewalls and smaller bottom area of ​​the chambers facilitate faster sediment discharge, reducing drainage volume. A larger energy dissipation chamber space can more effectively reduce water flow velocity and extend hydraulic residence time, thereby improving the settling efficiency of solid particles.

[0051] According to a second aspect of this application, an aquarium is provided, including a filter media chamber, biological filter media, and a circulation pump, as well as an aquarium solid-liquid separation device constructed according to the above preferred design. As shown in Figures 2, 6, and 9, an inlet 7 is located at the bottom of the aquarium for absorbing solid pollutants (such as fish waste, food residue, etc.) from the bottom of the aquarium. The inlet 7 is connected to an inlet channel 2. Water carrying solid pollutants is drawn in by the inlet 7 and flows into the inlet channel 2, then into the energy dissipation chamber 1. When the water flows from the inlet channel 2 into the energy dissipation chamber 1, the flow velocity drops sharply due to the increase in the chamber volume, and the kinetic energy of the water rapidly decreases. The solid pollutants carried in the water settle due to gravity, and the settled solid pollutants settle into the settling chamber. In chamber 3, water flows through energy dissipation chamber 1 and exits from the top of energy dissipation chamber 1, achieving solid-liquid separation. After the water flows through the solid-liquid separation device of the aquarium enters the filter media chamber 311, it comes into contact with the biological filter media 312 and completes biological purification. The biological filter media 312 in the filter media chamber 311 can be a porous structure, which effectively increases the surface area for microbial attachment and enhances the degradation capacity of harmful substances such as ammonia nitrogen. The water flowing through the biological filter media 312 is then pumped out by the circulation pump 313 and transported to the aquarium through the circulation water outlet 314, completing the water purification cycle.
