Description

Technical Field

[0001] This utility model relates to the field of aquarium equipment technology, specifically to a sedimentation filter for vertical fish tanks. Background Technology

[0002] In ornamental fish breeding and aquarium ecosystem maintenance, an efficient and stable filtration system is crucial for maintaining clear water and ensuring the health of aquatic life. Currently, most mainstream aquarium filtration devices on the market, whether built-in filters, hang-on waterfall filters, or some canister filters, generally employ an "internal layered filtration" design in their core filtration structure. This design typically involves tightly stacking or layering various functional filter media (such as filter cotton, bio-cotton, ceramic rings, and bio-balls) inside the filter chamber.

[0003] This type of design aims to achieve multi-functional integrated filtration: the physical filter media (such as fine filter cotton) located at the inlet or upper layer is responsible for intercepting larger solid waste particles such as fish waste, food scraps, and algae; the biological filter media located at the bottom layer is responsible for cultivating nitrifying bacteria to decompose toxic substances such as ammonia nitrogen and nitrite in the water, completing the biological purification process. However, this traditional "internal layer-by-layer filtration" structure has significant and urgent defects in practical applications: solid waste such as fish waste and food scraps are largely trapped in the physical filter layer (especially the uppermost fine filter cotton). Over time and with increased usage, this solid waste accumulates rapidly, causing severe clogging of the physical filter layer. Clogging is more frequent and severe, especially when the feeding amount is slightly larger or the stocking density is higher. When severe clogging is not detected and cleaned by the user in time, water cannot flow smoothly through the physical filter layer. This can easily lead to an abnormal rise in the water level inside the filter, which may eventually overflow from the filter gaps, cover, or inlet, causing water leakage from the aquarium.

[0004] To prevent the aforementioned clogging, flow reduction, and overflow issues, users must frequently clean or replace the physical filter media. This not only increases the workload and cost of daily maintenance (replacing filter media), but the cleaning process, especially for built-in filters or complex filter cartridges, is often quite cumbersome. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a horizontal aquarium sedimentation filter that can effectively eliminate physical filter layer blockage, maintain stable water flow, and reduce maintenance frequency and cost.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A vertical aquarium sedimentation filter includes a filter box body. A bottom partition is located in the middle of the bottom surface of the filter box body, dividing the bottom area of ​​the filter box body into a sedimentation zone and a water inlet zone. An inner partition is located above the bottom partition and the water inlet zone within the filter box body. The inner partition, together with the bottom and side walls of the water inlet zone, forms a water inlet cavity. A connecting channel is formed between the bottom of the inner partition and the top of the bottom partition, connecting the sedimentation zone and the water inlet cavity. The surface of the inner partition is a guide slope inclined towards the sedimentation zone to guide water flow and sediment deposition. A water inlet is located at the position corresponding to the water inlet cavity, communicating with the water inlet cavity. A drain outlet is located at the position corresponding to the sedimentation zone, communicating with the sedimentation zone. A drain valve is installed at the drain outlet. An outlet / flushing port is located at the top of the filter box body, above the guide slope, communicating with the interior of the filter box body.

[0007] In this invention, when in filtration mode, water enters the inlet chamber through the inlet, which reduces the water flow rate. The water then flows through the connecting channel towards the sedimentation zone. After exiting the connecting channel, fish waste and food residue, being denser than water, settle downwards in the sedimentation zone. After exiting the connecting channel, the water flows upwards along the sidewall and forms a vortex within the filter box under the constraint of the sidewall and the guide slope. As the water flows towards the guide slope in the vortex direction, its kinetic energy gradually decreases, and some lighter impurities slowly settle downwards. Because the water flow is closer to the guide slope, these impurities settle better on the guide slope, while the cleaner water is drawn out through the outlet / flushing port at the top of the guide slope. When internal cleaning is required after a period of use, stop supplying water to the filter box and open the drain valve. Fish waste and residue in the sedimentation zone will be discharged with the water flow. After the water in the filter box is drained, the outlet / flushing port can be used as the inlet for flushing water. Simply connect external flushing water to the outlet / flushing port, and the flushing water enters the filter box, impacting the high point of the guide slope and flowing along the guide slope towards the sedimentation zone. This simultaneously flushes the fish waste and residue deposited on the guide slope to the sedimentation zone for discharge. This invention utilizes the physical properties of sedimentation to separate fish waste and residue from the water without affecting the water flow. Furthermore, the discharge of residual fish waste and residue through flushing eliminates the need for consumables, reducing operating costs.

[0008] As an optimization, a diversion plate is provided downwards at the bottom of the inner segment corresponding to the position of the water inlet chamber. The diversion plate, together with the bottom and sidewall of the water inlet chamber, forms a diversion channel extending upwards from the bottom of the water inlet chamber to the connecting channel. The water inlet is located close to the upper part of the water inlet chamber, and the water outlet direction of the water inlet is opposite to that of the diversion plate. After the water enters the water inlet chamber, some fish waste and residue will settle at the bottom of the water inlet chamber. By setting the diversion plate to form a diversion channel and positioning the water outlet at the bottom of the water inlet chamber, the residue settled at the bottom of the water inlet chamber can be carried out.

[0009] As an optimization, the bottom segment has a guide slope inclined towards the bottom of the sedimentation zone on its top surface, corresponding to the port of the connecting channel on the side where the sedimentation zone is located. This causes the port of the connecting channel on the side where the sedimentation zone is located to form a flared opening with a gradually increasing cross-sectional width. Flaring also reduces the outlet flow rate, allowing impurities to settle better within the sedimentation zone.

[0010] As an optimization, the guiding slope consists of at least two continuously arranged segmented slopes from top to bottom, with the angle between each segmented slope and the horizontal plane decreasing sequentially from top to bottom. The outlet / flushing port corresponds to the segmented slope located at the highest point. Observation shows that most fish waste and residue are mainly deposited at the lower end of the guiding slope. In order to rinse the residue more thoroughly, the angle between the segmented slope and the horizontal plane at the upper position is larger, which can reduce the impact on the flow rate of the rinsing water and better carry impurities into the sedimentation zone.

[0011] As an optimization, a baffle plate is provided inside the filter box body and directly below the outlet / rinse port. The baffle plate extends along the width direction parallel to the guide slope, and its two ends are respectively fixedly connected to the corresponding side surfaces of the filter box body. A rinsing port is formed between one long side of the baffle plate and the side surface of the filter box body where the guide slope is located, and a suction port is formed between the other long side of the baffle plate and the top of the filter box body. The flow area of ​​the outlet / rinse port is larger than the flow area of ​​the rinsing port and smaller than the sum of the flow areas of the rinsing port and the suction port. Because the outlet / rinse port is a dual-purpose interface, during rinsing, after water enters, the flow area of ​​the outlet / rinse port is larger than that of the rinsing port. Therefore, the rinsing water can be discharged through the entire rinsing port and flow along the side wall of the filter box body to the guide slope, so that every position of the guide slope can be rinsed without leaving any rinsing dead corners. When in filtration mode, in order to better absorb water, the sum of the flow areas of the flushing outlet and the suction outlet must be greater than the flow area of ​​the outlet / flushing outlet, thereby avoiding any impact on the flow rate.

[0012] As an optimization, an exhaust port is provided on the top of the filter box body, and an exhaust valve is installed at the exhaust port. When the drain valve is opened, the exhaust valve is also opened simultaneously, allowing the filter box body to communicate with the outside atmosphere, thereby making the drainage smoother.

[0013] Compared to existing technologies, this invention does not use traditional filtration methods, thus effectively avoiding various problems caused by solid waste clogging in traditional filter chambers. Even with long-term operation, it can maintain a high flow rate. In addition, it reduces the cost of consumables for long-term use, making overall maintenance more convenient and economical. Furthermore, this invention can be installed independently, introducing water from the aquarium into the device for water treatment via a pump pipe, or it can be integrated with the aquarium, becoming part of the aquarium, thus making it more aesthetically pleasing overall.

An inner dividing part 3 is provided in the filter box body 1 above the bottom dividing part 2 and the water inlet area. The inner dividing part 3, together with the bottom and side wall of the water inlet area, forms a water inlet cavity. A connecting channel 4 is formed between the bottom of the inner dividing part 3 and the top of the bottom dividing part 2, connecting the sedimentation area and the water inlet cavity. The surface of the inner dividing part 3 is a guide slope inclined towards the sedimentation area to guide water flow and sediment deposition. A water inlet 5 is provided in the filter box body 1 corresponding to the water inlet cavity and communicating with the water inlet cavity. A drain outlet 6 is provided in the filter box body 1 corresponding to the sedimentation area and communicating with the sedimentation area. A drain valve is installed at the drain outlet 6. A water outlet / flushing outlet 7 is provided in the top of the filter box body 1 and above the guide slope, communicating with the inside of the filter box body 1.

[0017] In this specific embodiment, a diversion plate 8 is provided at the bottom of the inner partition 3 corresponding to the position of the water inlet cavity. The diversion plate 8, together with the bottom and side wall of the water inlet cavity, forms a diversion channel extending upward from the bottom of the water inlet cavity to the connecting channel 4. The position of the water inlet 5 is close to the upper part of the water inlet cavity, and the water outlet direction of the water inlet 5 is opposite to the diversion plate 8.

[0018] In this specific embodiment, the bottom dividing part 2 has a guide slope that is inclined toward the bottom of the sedimentation zone on its top surface and at the port of the connecting channel 4 on the side where the sedimentation zone is located, so that the port of the connecting channel 4 on the side where the sedimentation zone is located forms an flared opening with a gradually increasing cross-sectional width.

[0019] In this specific embodiment, the guide slope is composed of at least two segmented slopes 9 arranged continuously from top to bottom. The angle between each segmented slope 9 and the horizontal plane decreases sequentially from top to bottom. The water outlet / flushing port 7 corresponds to the segmented slope 9 located at the highest point.

[0020] In this specific embodiment, a baffle plate 10 is provided inside the filter box body 1 and directly below the outlet / flushing port 7. The baffle plate 10 extends along the width direction parallel to the guide slope and its two ends are respectively fixedly connected to the corresponding side of the filter box body 1. A flushing port is formed between one long side of the baffle plate 10 and the side of the filter box body 1 on the side where the guide slope is located. A suction port is formed between the other long side of the baffle plate 10 and the top of the filter box body 1. The flow area of ​​the outlet / flushing port 7 is larger than the flow area of ​​the flushing port and smaller than the sum of the flow areas of the flushing port and the suction port.

[0021] In this specific embodiment, the top of the filter box body 1 is provided with an exhaust port 11, and an exhaust switch valve is installed at the exhaust port 11.

[0022] In the specific implementation process, the filter box body is placed below the fish tank. The water inlet at the bottom of the fish tank is connected to the water outlet / flushing outlet of the filter box body through a water pump, and a solenoid valve is installed at the water outlet / flushing outlet. The water outlet at the bottom of the fish tank is connected to the water inlet of the filter box body through a pipe, and a solenoid valve is installed at the water inlet of the filter box body. In addition, the drain valve and the vent valve are also solenoid valves. A water immersion sensor is also installed at the outlet of the vent valve to detect the water discharged from the vent valve. In this way, by setting up a controller, it can receive signals from the water immersion sensor and can also connect and control the water pump and each solenoid valve separately: In filtration mode, the solenoid valves at the inlet and outlet / flushing ports on the filter box body are opened, the water pump is turned on, and the water in the aquarium enters the filter box body through the pipes under the action of gravity, where impurities are settled. The water pump then draws the relatively clean water from the top back into the aquarium through the outlet / flushing port on the filter box body; In cleaning mode, the water pump, the solenoid valves at the inlet and outlet / flushing ports are closed, and the drain valve and air vent valve are opened to drain the water from the filter box body first, and then the outlet / flushing port is opened. The solenoid valve at the water inlet, under the influence of gravity, draws water from the aquarium back through the water pump and into the outlet / flushing port, rinsing the guide slope. After the filter box body completes its drainage and rinsing process, the drainage valve and the solenoid valve at the outlet / flushing port are closed, while the solenoid valve at the inlet of the filter box body is opened to fill the filter box body with water and expel air. Once all the air in the filter box body has been expelled, water overflows from the vent valve. The water immersion sensor detects the water and sends a signal to the controller, which then closes the vent valve. Afterward, the solenoid valve at the outlet / flushing port and the water pump are opened, re-entering the filtration mode. All of these controls can be preset within the controller, automatically controlling each component in each stage, achieving unmanned automated management and making it more convenient to use.
