Description

Technical Field

[0001] This utility model relates to the field of aquarium filtration technology, specifically to a bubble-spinning wastewater filter. Background Technology

[0002] Fish tanks are a popular decorative item in modern homes. However, if food scraps and fish waste are not cleaned for a long time, they will pollute the water and affect the growth and health of the fish. Therefore, how to deal with food scraps and fish waste in fish tanks has become a very important issue.

[0003] To clean up feed residue and fish waste, for example, Chinese utility model patent application number CN202322652351.8 discloses an aquarium filter separator, which includes a separator body. The separator body includes a separation part, a support part, and a waste discharge part that are sequentially assembled and connected. The top of the separation part is provided with a water inlet, and the inside of the water inlet is provided with a filter component that can rotate axially. The side wall of the separation part is provided with a water outlet. The inside of the support part is provided with a support funnel, and the top of the support funnel is provided with a circular groove for installing the filter cartridge. The bottom side wall of the waste discharge part is provided with a sewage outlet. The bottom of the support funnel is provided with a waterproof motor. The drive end of the waterproof motor is connected to the bottom of the filter cartridge and drives the filter cartridge to rotate axially. By using the waterproof motor to directly drive the filter cartridge to rotate, the entire filter cartridge rotates, thereby cleaning up the residue or fish waste clogging the filter cartridge, resulting in a better and more thorough cleaning effect.

[0004] However, some problems still exist. Although the waterproof motor is connected to the bottom of the filter cartridge and drives the filter cartridge to rotate axially, the cleaning effect is better and more thorough. However, the waterproof motor requires an additional drive source, which is not energy-efficient and economical, and does not conform to the design trend of energy conservation and environmental protection. In addition, the waterproof motor is not easy to maintain inside the device, and the residue or fish waste continues to decompose inside the device. Dissolved pollutants may be released back into the aquarium water, causing secondary pollution of the water quality. Therefore, a bubble self-rotating sewage filter is proposed to solve the above problems. Utility Model Content

[0019] 1. This bubble-rotating wastewater filter can be used for aquarium filtration. Aquarium wastewater enters the main body through the inlet, and the water flow drives the filter components to rotate continuously. The wastewater passes through the filter components to effectively prevent residue or feces from clogging the filter, thus completing the filtration process. This significantly improves filtration efficiency and reduces maintenance frequency, as well as reducing complex electrical components, which is in line with the trend of energy-saving and environmentally friendly design.

[0020] 2. This bubble-driven wastewater filter uses bubbles generated by the bubble stones to perform both physical transport and biological purification functions. The bubbles lift and transport residue and feces to the collection bin, promptly cleaning dissolved pollutants and achieving automatic cleaning of the filter components. In addition, the bubbles increase dissolved oxygen, promote the metabolic activities of aerobic microorganisms, and carry out deep biodegradation treatment of wastewater, achieving dual purification and greatly improving overall practicality.

[0021] 3. When cleaning the sludge collection chamber, this bubble-rotating sewage filter only requires closing the solenoid valve to increase the air pressure inside the sludge collection chamber. The air pressure can be used to discharge the sediment inside the sludge collection chamber. This design eliminates the need for additional sewage pumps and other complex structures, realizing three uses of one gas, improving the reusability of the equipment, and making the overall structure more compact and reasonable.

[0022] 4. This bubble-rotating sewage filter can dynamically change the sewage pressure by adjusting the components, thereby precisely controlling the rotation speed of the filter components. This structure is simple and efficient, further optimizing the filtration effect and overall adaptability. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] Please see Figures 1 to 3 as well as Figures 6 to 8 This embodiment of a bubble-spinning wastewater filter includes a main body 1. A sealing cover 2 is fixed to both the top and bottom of the main body 1. The top and bottom sealing covers 2 are identical to improve mold utilization and reduce mold opening costs. The sealing cover 2 includes a sealing plate 201 and a limiting block 202. A connecting plate 205 is fixed to one side of each of the two sealing plates 201. Sealant is applied to the outer surface of the connecting plate 205 to ensure a reliable seal when the sealing cover 2 is installed with the main body 1. The upper and lower sides of the main body 1 are fixed to the two sealing plates 201 respectively. The opposite side of the two sealing plates 201 is fixed to the limiting block 202. The two limiting blocks 202 are used to clamp and position the filter assembly 6.

[0034] A sealing back plate 3, which is fixed to the sealing cover 2, is fixed on the left side of the main body 1. The sealing back plate 3 is sealed and fixed to the main body 1. A water inlet 4 and a sewage outlet 5, which penetrate into the interior of the main body 1, are fixed on the left side of the sealing back plate 3. A filter assembly 6, which penetrates the main body 1, is provided between the two sealing covers 2. The filter assembly 6 is used to filter the sewage in the fish tank.

[0035] The top of the filter assembly 6 is connected to a connector 7 extending to the outside of the main body 1. The left side of the connector 7 is connected to a three-way connector 8 extending into the inside of the main body 1. The three-way connector 8 is sealed to the main body 1. The connector 7 and the three-way connector 8 form a guide channel for guiding residue, feces and air bubbles. Based on the principle of gravity separation, the residue and feces have their own weight. When flowing through the three-way connector 8, the residue and feces settle downward under the action of gravity and enter the interior of the main body 1 to collect, which is convenient for centralized cleaning.

[0036] The left side of the three-way connector 8 is connected to a connecting pipe 9 that extends through the sealing back plate 3 to its left side. A solenoid valve 10 is installed on the connecting pipe 9. The solenoid valve 10 is connected to an external controller to receive switching commands. Its control program is conventional technology in the field. The solenoid valve 10 is located outside the sewage to prevent sewage corrosion and can improve the service life of the solenoid valve 10. A sludge collection box 11 is fixed on the right side of the connecting pipe 9. The sludge collection box 11 is used to collect and temporarily store dissolved pollutants, tiny particles and microorganisms carried by air bubbles. The sludge collection box 11 needs to be manually cleaned regularly. An adjustment component 12 is also installed inside the main body 1. The adjustment component 12 is used to adjust the water pressure. A drain pipe 13 is connected to the left side of the drain outlet 5. The top of the drain pipe 13 is higher than the top of the sludge collection box 11, so that when the solenoid valve 10 is open, the air bubbles will move towards the sludge collection box 11 first.

[0037] Wastewater flows into the main body 1 through the inlet 4 and enters the filter assembly 6 to complete filtration. The residue, feces and air bubbles generated by the filter assembly 6 are guided to the tee connector 8 through the connector 7. When flowing through the tee connector 8, the residue and feces sink downward into the main body 1 under the action of gravity, while the air bubbles continue to be guided along the connecting pipe 9 and through the solenoid valve 10, and are finally stored in the sludge collection box 11.

[0038] Please see Figure 5 In this embodiment, the filter assembly 6 includes a positioning block 601, an air bubble 602, a dirt-collecting inverted cone 603, a filter screen cylinder 604, an impeller 605, a connecting block 606, and a guide tube 607. The top of the bottom sealing cover 2 is fixed to the positioning block 601. Mounting blocks 203 are fixed to opposite sides of the two sealing plates 201. A suction groove 609 communicating with the bottom is opened on the right side of the positioning block 601. The mounting block 203 is located inside the suction groove 609. The mounting block 203 provides an installation reference for the positioning block 601, enabling its positioning. Precisely defined, the inner bottom wall of the positioning block 601 is fixed to the air stone 602. The bottom of the air stone 602 is provided with an air inlet, which is connected to an external air pump through a hose. The rising air bubbles generated by the connection between the air stone 602 and the external air pump form a negative pressure zone in the positioning block 601, which sucks the residue in the sludge-collecting cone 603 into the positioning block 601. The sludge suction tank 609 allows the residue and feces in the sludge-collecting cone 603 to enter the interior of the positioning block 601. At the same time, the rotation of the sludge-collecting cone 603 ensures that all the surrounding dirt can be captured by the sludge suction tank 609.

[0039] The outer surface of the positioning block 601 is rotatably connected to the inverted cone 603 for collecting fish food and feces after filtration. Its converging effect facilitates efficient capture. The top of the inverted cone 603 is fixed to the filter screen 604 located outside the main body 1. The filter screen 604 is used to filter the wastewater in the aquarium. The top of the filter screen 604 is fixed to the impeller 605. The impeller 605 is driven to rotate by the wastewater and drives the filter screen 604 and the inverted cone 603 to rotate synchronously. A baffle 610 is fixed on the outer surface of the impeller 605. There is a gap between the baffle 610 and the water inlet 103. The baffle 610 reduces the leakage caused by the wastewater directly impacting the gap between the impeller 605 and the main body 1 when the wastewater moves downward through the impeller 605 into the filter screen 604.

[0040] The impeller 605 is rotatably connected to the connecting block 606 fixed to the top sealing cover 2. The bottom limiting block 202 is fixed to the positioning block 601, and the top limiting block 202 is fixed to the connecting block 606. The bottom of the connecting block 606 is fixed to the guide tube 607 fixed to the positioning block 601. The connecting block 606 adopts a hollow structure to form a bubble channel. The bubbles in the guide tube 607 pass through it and enter the connector 7. The bubble stone 602 is located inside the guide tube 607. The bottom of the bubble stone 602 is connected to the output pipe of the air pump to generate microbubbles. The external air pump is far away from the water source, which can improve the service life and facilitate subsequent maintenance.

[0041] A lamp tube 608 is fixed between the positioning block 601 and the connecting block 606. Both the lamp tube 608 and the guide tube 607 are made of acrylic material. Acrylic material has good light transmittance, corrosion resistance and is easy to process. The precise installation of the positioning block 601 ensures that the irradiation direction of the lamp tube 608 is always facing the right. The ultraviolet lamp is sealed inside the lamp tube 608 with sealant, which can perform ultraviolet sterilization. The interiors of the water inlet tank 103, the filter screen cylinder 604, the positioning block 601, the guide tube 607, the connecting block 606 and the connector 7 are interconnected. Sewage enters the interior of the filter screen cylinder 604 through the water inlet tank 103, while feces and waste pass through the positioning block 601, the guide tube 607, the connecting block 606 and the connector 7 in sequence, and finally reach the three-way connector 8 to achieve diversion.

[0042] The filter cylinder 604 effectively filters impurities. When sewage enters its interior, it drives the impeller 605 and the filter cylinder 604 to rotate, using centrifugal force to automatically remove impurities and prevent clogging. This sewage driving method has a simple structure, requires no additional power, significantly improves filtration efficiency and reduces maintenance frequency, reduces complex devices such as electrical components, and conforms to the trend of energy-saving and environmentally friendly design.

[0043] Please see Figure 4 In order to dynamically adjust the water pressure, the main body 1 in this embodiment includes a box 101. The upper and lower sides of the box 101 are fixed to the sealing cover 2. A water inlet trough 103 communicating with the top is opened on the left side of the box 101. A sludge collection chamber 102 located at the bottom of the water inlet trough 103 is opened on the left side of the box 101. The water inlet 4 is connected to the inside of the water inlet trough 103. The water inlet trough 103 is used to guide the sewage to flow into the interior of the filter assembly 6. The drain outlet 5 and the three-way connector 8 are both connected to the inside of the sludge collection chamber 102. The sludge collection chamber 102 is used to collect the filtered residue or feces to prevent dissolved pollutants from being released back into the aquarium water and causing secondary pollution of the water quality. The drain outlet 5 adopts an elbow structure to reduce the dead space of the drain to 5mm. If a straight pipe drain outlet 5 is used, the distance will be significantly increased due to the necessary sealing structure and pipe wall thickness.

[0044] The housing 101 has a positioning groove 104 that communicates with the water inlet 103 inside. The upper and lower sides of the housing 101 have sealing grooves 105 that are adapted to the connecting plate 205. The connection plate 205 and the sealing groove 105 can effectively increase the contact area between the main body 1 and the sealing cover 2, thereby effectively ensuring the overall sealing performance. The adjustment component 12 includes an adjustment rod 1201, an adjustment plate 1202, a first permanent magnet 1203 and a second permanent magnet 1204. The positioning groove 104 is rotatably connected to the adjustment rod 1201. The two sealing plates 201 have connecting grooves 204 on opposite sides. The top connecting groove 204 is rotatably connected to the adjustment rod 1201. The connecting groove 204 makes the adjustment rod 1201 more stable when it rotates.

[0045] The back of the adjusting rod 1201 is fixed to the adjusting plate 1202. The adjusting rod 1201 allows the adjusting plate 1202 to rotate with the adjusting rod 1201, thereby allowing the adjusting plate 1202 to adjust the flow area and improve the overall practicality. The front of the adjusting plate 1202 is fixed to the first permanent magnet 1203, and the inner wall of the water inlet tank 103 is fixed to the second permanent magnet 1204. The first permanent magnet 1203 and the second permanent magnet 1204 have the same magnetic polarity when they are close to each other, generating a repulsive force. The adjusting component 12 is not limited to magnetic adjustment.

[0046] The highly integrated design of the whole unit continuously and collaboratively completes four functions in a relatively compact device: 604 filter cylinder anti-clogging, air-lift collection of solid residues, air flotation separation of fine particles and dissolved pollutants, and magnetic adjustment, which greatly improves the overall practicality.

[0047] The working principle of the above embodiments is as follows:

[0048] (1) The wastewater from the aquarium enters through the inlet 4 and the inlet tank 103. The water flow impacts the impeller 605, driving it to rotate. Since the impeller 605, the filter screen 604, and the inverted cone 603 are fixedly connected and coaxially arranged, when the water flow drives the impeller 605 to rotate, it simultaneously drives the filter screen 604 and the inverted cone 603 to rotate, so that the wastewater passes through the rotating filter screen 604 to complete the filtration. The continuous rotation of the filter screen 604 effectively prevents residue or feces from accumulating and clogging on the filter screen surface, ensuring the stability of the filtration efficiency. This driving method has a simple structure and does not require additional power. When continuously filtering wastewater, it continuously pushes the filter screen 604 to rotate, preventing the filter screen 604 from clogging. It can significantly improve the filtration efficiency and reduce the maintenance frequency, reduce complex devices such as electrical appliances, and conform to the trend of energy-saving and environmentally friendly design.

[0049] (2) Start the external air pump connected to the air stone 602 to generate an air bubble flow. The residue or feces that are filtered and deposited at the bottom of the sludge-collecting cone 603 are sucked into the suction tank 609 of the positioning block 601 under the action of gravity and air lift generated by the air bubble flow. They move upward along the guide pipe 607 with the air bubbles. When the impurity mixture flows through the connecting block 606 and the connecting head 7 and passes through the three-way connector 8, the heavier residue and feces fall downward into the sludge collection bin 102 due to gravity, while the lighter air bubbles carry the small particles, microorganisms and dissolved pollutants to continue to rise and enter the sludge collection box 11 through the connecting pipe 9 for separation and temporary storage. In addition, the air bubbles increase the dissolved oxygen content, promote the activity of aerobic microorganisms, and carry out deep biological treatment of sewage. This process realizes the dual cleaning of solid waste separation and air flotation purification, and prevents secondary pollution, greatly improving the overall practicality.

[0050] (3) When cleaning the sludge collection chamber 102, the solenoid valve 10 is closed. The bubbles generated by the air stone 602 are blocked from flowing to the sludge collection box 11. Instead, they are forced to flow down through the guide pipe 607, connecting block 606, connector 7 and tee connector 8 and injected into the sludge collection chamber 102. The gas accumulates and pressurizes in the sludge collection chamber 102, forming positive pressure, which pushes the impurity mixture inside the sludge collection chamber 102 to move upward along the drain pipe 13 to complete the discharge. This design uses the air pump to achieve pressurized discharge, without the need for additional cleaning pumps or complex structures, making the overall structure more compact and reasonable.

[0051] (4) When the sewage flows through the inlet tank 103 to the filter assembly 6, it needs to pass through the adjustment assembly 12. This assembly uses the same pole repulsion force between the first permanent magnet 1203 and the second permanent magnet 1204 to provide the initial magnetic repulsion force for the adjustment plate 1202. The pressure of the small flow rate water is not enough to overcome this magnetic repulsion force. The adjustment plate 1202 maintains a small opening and closing degree to maintain a high water pressure to drive the filter assembly 6 to rotate. When the flow rate is large, the increased water pressure torque overcomes the magnetic repulsion force, pushes the adjustment rod 1201 and drives the adjustment plate 1202 to rotate to increase the flow area, thereby reducing the water pressure and stabilizing the driving speed of the filter assembly 6. This mechanism realizes the adaptive adjustment of the inlet water pressure, further optimizing the filtration effect and overall adaptability.
