Description

Technical Field

[0001] This utility model relates to the field of aquarium filtration technology, specifically to an aquarium filtration device with dual filtration and chemical cleaning. Background Technology

[0002] Aquarium filtration is an important part of fishkeeping. It uses special filter media to remove pollutants generated during the fishkeeping process, restoring the water quality in the aquarium to a usable state. The quality of filtration directly affects the growth and reproduction of fish.

[0003] For example, Chinese invention patent CN201910307561.9 discloses an ecological fish tank capable of separating fish excrement, including a tank body and a base. A grid mesh is provided between the tank body and the base, and a funnel-shaped waste collector is located below the grid mesh inside the base. The funnel-shaped waste collector in this invention can collect the excrement discharged by the fish in the tank, achieving separation of excrement and water. The fish tank has a cleaning and filtration device, which uses a water pump to pump water from the fish tank to the filtration area for automatic circulation filtration and automatic cleaning of the filter cloth, and finally discharges the filtered turbid water and impurities. The fish tank has an automatic water level detection device that automatically replenishes water when the water level drops, and replenishes water through a float inlet valve. When the water level is too high, water is drained through an overflow pipe to adjust the water level. The fish tank also has a multi-loop water heating function, which intelligently controls the temperature of the fish tank through the connection and control of the controller and various functional components, achieving intelligent control.

[0004] However, this device still has certain limitations. Modern aquariums are usually decorated with river sand and pebbles.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] 1. This dual-filtration and chemical cleaning aquarium filtration system effectively removes larger or harder impurities from the water through a single-stage filtration process, preventing them from entering the subsequent fine filtration stage. This significantly reduces the risk of the filter cloth being scratched or structurally damaged. Furthermore, the wastewater diffuses from the inside to the outside of the filter cloth, effectively increasing the filtration area and reducing filter cloth clogging.

[0020] 2. This dual-filtration and chemical cleaning aquarium filtration system features a sludge collection drawer and filter cloth nozzle positioned at the top of the water level. This design eliminates the need for the filter cloth nozzle to overcome water pressure, significantly increasing the water flow impact and thus effectively enhancing the rinsing efficiency of the filter cloth. The rinsed impurities are collected in the sludge collection drawer, achieving dry and wet separation and preventing impurities from fermenting in water for extended periods. This fundamentally prevents the generation of odors. This structural design not only improves the overall cleaning efficiency but also enhances the overall hygiene and user experience.

[0021] 3. This dual-filtration and chemical cleaning aquarium filtration system mixes purified water with the chemical solution in the dosing component during the rinsing water pump supplying water to the filter cloth nozzle. The resulting mixture is then sprayed onto the filter cloth surface. This mixture effectively decomposes the dirt attached to the filter cloth, significantly improving the rinsing effect and cleaning efficiency. At the same time, the dosing component also adds another type of chemical solution to the aquarium to regulate the water quality, promote the growth of nitrifying bacteria, and adjust the pH value, thereby optimizing the overall wastewater treatment performance and practical value.

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 4 This embodiment of a dual-filtration and chemical cleaning aquarium filtration device includes a main body 1. The main body 1 has a filter chamber 2, a water purification chamber 3, a medication replenishment chamber 4, and a water pump chamber 5. The filter chamber 2, water purification chamber 3, medication replenishment chamber 4, and water pump chamber 5 are all independent sealed chambers, and each chamber is isolated from the others by a sealing structure. The main body 1 has a filter cloth device 6 located inside the filter chamber 2. The filter cloth device 6 has a primary filter 7 inside it. The filter cloth device 6 has two liquid level sensors 8 inside it. When the water level rises to a predetermined height, the liquid level sensors 8 send an electrical signal to the control panel 15.

[0034] The main housing 1 houses a dosing assembly 9 located inside the replenishment chamber 4. The dosing assembly 9 includes a medicine tank 901 slidably connected to the main housing 1 and extending through the front of the main housing 1. The medicine tank 901 is connected to the main housing 1 via a slide rail, allowing it to be pulled out from inside the main housing 1 along a preset trajectory for replenishing medicine or cleaning / maintenance operations. A medicine tank partition 902 is fixed inside the medicine tank 901, dividing the internal space of the medicine tank 901 into two parts, allowing the medicine tank 901 to store two types of medicine. The left side of the medicine tank partition 902 stores a cleaning agent for cleaning the filter cloth 606, such as... Liquid agents, not limited to those with functions of decomposing organic matter and sterilization and disinfection, are mixed with purified water during the cleaning process and sprayed onto the surface of filter cloth 606 to enhance the rinsing and decontamination effect. The right side of the medicine tank partition 902 stores water quality conditioners for treating aquaculture water. Water quality conditioners may include, but are not limited to, flocculants for flocculating suspended matter, bacterial culture solutions for promoting the growth of nitrifying bacteria, or pH regulators, etc., for chemical purification of water. The inside of the medicine tank 901 is fixed with a peristaltic pump 903 located on the right side of the medicine tank partition 902. The peristaltic pump 903 is connected to the fish tank and adds water quality conditioners to the fish tank at regular intervals.

[0035] The main housing 1 houses a flushing water pump 10 located inside the pump chamber 5. The suction end of the flushing water pump 10 is fixed with a suction pipe 11 that extends into the clean water chamber 3. The suction pipe 11 is connected to the dosing assembly 9. The suction pipe 11 is a three-way pipe; its first end is connected to the suction end of the flushing water pump 10, its second end is connected to the chemical tank 901, and its third end extends into the clean water chamber 3. The inner diameter of the second end of the three-way pipe is smaller than the inner diameter of the third end. During operation, the flushing water pump 10 simultaneously draws water from the clean water chamber 3. The purified water and medicine tank 901 contain medicine, and the proportion of purified water being drawn out is greater than that of medicine. The third end of the three-way pipe is located on the left side of the medicine tank partition 902. The outlet of the flushing water pump 10 is connected to the nozzle pipe 12 located inside the filter chamber 2. The three-way pipe is shown in the form of a straight pipe, which is only for the purpose of clear drawing and easy understanding. Those skilled in the art should understand that in order to achieve dynamic connection with the movable medicine tank 901, the three-way pipe should be a flexible pipe, corrugated pipe, hinged pipe or pipe made of bendable material in actual application.

[0036] A float valve 13 and a water pump 14, penetrating to the outside of the main housing 1 and located inside the water purification chamber 3, are fixed to the rear side wall of the inner cavity of the main housing 1. Both the float valve 13 and the water pump 14 are used to replenish purified water into the water purification chamber 3. Specifically, the inlet end of the float valve 13 can be connected to an external water supply pipe, such as a tap, to replenish water. When the water level reaches the float valve 13, the float valve 13 closes, automatically stopping the water replenishment. The inlet end of the water pump 14 can be placed in a water container to draw water from the container to replenish the water. A control panel 15 is fixed to the front of the main housing 1. The control panel 15 is connected to the drive motor 6021 and the turbidity meter. Sensor 704, liquid level sensor 8, and water pump 14 are all signal connected to receive sensor signals and send operation commands to each actuator. The back of the primary filter 7 is fixed with an inlet 16 that penetrates the main housing 1 and an automatic drain outlet 18. The primary filter 7 includes a housing 701 that is fixed to the back of the filter cloth frame 601 and penetrates into the interior of the filter cloth frame 601. The front of the housing 701 is provided with an inwardly recessed receiving groove. The filter cartridge 702 is fixed inside the receiving groove. The filter cartridge 702 is used for preliminary filtration of sewage and can effectively intercept hard particles in the sewage, thereby preventing the subsequent filter cloth 606 from being scratched and damaged.

[0037] Inside the housing 701, a solenoid valve 703 and a turbidity sensor 704 are fixed. The outlet of the solenoid valve 703 is connected to the automatic drain port 18. Inside the housing 701, there are an inlet tank 705 and a drain tank 706. The inlet port 16, the inlet tank 705, the filter cartridge 702 and the drain tank 706 are connected. The bottom wall of the drain tank 706 has an inclined surface. Due to the inclined surface, the filtered impurities can automatically flow to the solenoid valve 703 under the action of gravity, which facilitates centralized cleaning. The solenoid valve 703 and the turbidity sensor 704 are both located inside the drain tank 706. The turbidity sensor 704 is used to detect the concentration of impurities in the water. When the detected concentration exceeds the preset threshold, the sensor will send an electrical signal to the control panel 15. After receiving the signal, the control panel 15 will immediately start the solenoid valve 703 to perform the drain operation.

[0038] Please see Figures 5 to 9In this embodiment, the filter cloth device 6 includes a filter cloth frame 601 fixed to the main housing 1. An outlet 17 penetrating the main housing 1 is fixed to the back of the filter cloth frame 601. The filter cloth frame 601 is internally equipped with a drive assembly 602 and an adjustment assembly 603. The adjustment assembly 603 includes an adjustment rod 6034, two adjustment pipes 6031, an adjustment block 6032, and an adjustment spring 6033. The front and rear sides of the filter cloth frame 601 are fixed to the two adjustment pipes 6031 respectively. The interior of the adjustment pipe 6031 is slidably connected to the adjustment block 6032, and the interior of the adjustment block 6032 is slidably connected to the adjustment spring. The spring 6033 is fixed, and the two adjusting blocks 6032 are rotatably connected to the adjusting rod 6034. The elastic force of the adjusting spring 6033 provides a continuous upward thrust to the adjusting blocks 6032 and the adjusting rod 6034, so that the anti-slip band 605, which is in transmission cooperation with the adjusting rod 6034, is always in a taut state. This structure not only ensures the effective friction between the anti-slip band 605 and the drive head 6022, ensuring the stability of the entire transmission process, but also the adjusting tube 6031 wraps the adjusting block 6032 inside, making it easy to add lubricating oil later and preventing the internal spring from rusting due to the humid environment, which would cause the spring to fail.

[0039] The drive assembly 602 includes two drive heads 6022 rotatably connected to the filter cloth frame 601. A drive tube 6023 is fixed between the two drive heads 6022. A drive motor 6021 is fixed to the back of the filter cloth frame 601. The output shaft of the drive motor 6021 is fixed to the back drive head 6022. Both the anti-slip strip 605 and the outer surface of the drive head 6022 are provided with anti-slip textures. The two drive heads 6022 are identical parts to improve mold utilization and reduce mold opening costs. The anti-slip textures on the outer surface of the drive head 6022 increase the contact area between it and the anti-slip strip 605, thereby effectively enhancing the friction between them and further improving the reliability and stability of the transmission. The interior of the filter cloth frame 601... Two driven rods 604 are rotatably connected. Two anti-slip belts 605 are connected to the outer surfaces of the drive assembly 602, the adjustment assembly 603, and the driven rods 604. Limiting grooves are opened on the outer surfaces of the adjustment rod 6034 and the driven rods 604. The anti-slip belts 605 are located in the limiting grooves. The anti-slip belts 605 are placed inside the limiting grooves, which can constrain their movement trajectory during the transmission process and effectively prevent the anti-slip belts 605 from deviating, slipping, or axially moving, thereby ensuring the reliability and stability of the transmission. Filter cloths 606 are fixed on the outer surfaces of the two anti-slip belts 605. The filter cloths 606 are in a close fit with the filter cloth frame 601, which can prevent the filter cloths 606 from bulging due to the impact of water flow, causing sewage to overflow from the bulge.

[0040] The filter cloth frame 601 has a slidably connected internally to a sludge collection drawer 607 that extends through to the front of the main housing 1. Two level sensors 8 are fixed to the filter cloth frame 601. The bottom level sensor 8 is located at the bottom of the drive assembly 602, and the top level sensor 8 extends through to the inside of the sludge collection drawer 607. The top level sensor 8 monitors the water level inside the sludge collection drawer 607. When the water level rises to a preset height due to blockage in the sludge collection drawer 607, the level sensor 8 sends an electrical signal to the control panel 15. Upon receiving the signal, the control panel 15 displays corresponding information, prompting the user to clean the sludge collection drawer 607. The filter cloth nozzle 609 is located directly above the sludge collection drawer 607. The filter pore size of 07 is smaller than that of filter cloth 606, which allows the sludge collection drawer 607 to intercept impurities washed off the filter cloth 606, while the water drips back into the filter chamber 2, thereby reducing water waste. A scraper that fits against the drive assembly 602 is fixed on the right side of the sludge collection drawer 607. A rebound device 608 is fixed on the front of the filter cloth frame 601. The rebound device 608 is existing technology and is configured on the filter cloth frame 601. When the user presses the sludge collection drawer 607, the rebound device 608 is triggered and releases its elasticity, causing the sludge collection drawer 607 to pop out automatically, making it easy for the user to remove and clean. A filter cloth nozzle 609 that communicates with the nozzle pipe 12 is fixed inside the filter cloth frame 601.

[0041] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0042] The working principle of the above embodiments is as follows:

[0043] (1) Pull the medicine tank 901 forward to move it to the outside of the main body 1. Two kinds of medicines can be added into the medicine tank 901 respectively. When adding clean water into the clean water chamber 3, water can be added into the clean water chamber 3 through the float valve 13 or the water pump 14. When performing filtration, sewage enters the water inlet 705 of the housing 701 through the inlet 16 and then flows into the filter cartridge 702. After being filtered by the filter cartridge 702, the impurities in the sewage fall into the drain trough 706 due to gravity. The turbidity sensor 704 monitors the impurity concentration in real time. When too many impurities are detected, an electrical signal is transmitted to the control panel 15 to remind the user to clean. When cleaning, the solenoid valve 703 is opened, and the impurities can be discharged through the automatic drain 18. This can effectively intercept larger or harder impurities in the water, significantly reduce the risk of the filter cloth 606 being scratched or structurally damaged, and extend the cleaning and maintenance cycle, making the whole more practical.

[0044] (2) After being filtered by the filter cartridge 702, the sewage enters the filter cloth frame 601. During the outward flow, the sewage passes through the filter cloth 606 for secondary filtration. The filtered water enters the interlayer between the filter chamber 2 and the filter cloth frame 601, and is finally discharged from the outlet 17, completing the entire filtration process. When the filter cloth 606 becomes clogged, the sewage cannot permeate outward normally, causing the internal water level to rise. After the level sensor 8 contacts the water level, it sends an electrical signal to the control panel 15. The control panel 15 then starts the drive motor 6021, which drives the drive head 6022 and the drive tube 6023 to rotate synchronously, thereby causing the anti-slip belt 6 to rotate. 05 and filter cloth 606 move counterclockwise along the outer surface of drive head 6022, adjusting rod 6034 and driven rod 604. At the same time, control panel 15 starts flushing water pump 10, which sprays the mixture of medicine and purified water extracted from medicine tank 901 and purified water chamber 3 onto the moving filter cloth 606 through filter cloth nozzle 609 to rinse it. The washed-off impurities fall into the dirt collection drawer 607, and the water will flow back into the inside of filter cloth 606, thus completing the collection and cleaning of impurities. This structural design not only reduces water waste and improves the overall cleaning efficiency, but also improves the overall hygiene conditions and user experience.
