Technical Field
[0001] This utility model relates to the field of aquarium accessories technology, and in particular to a fish waste and particulate matter filtration device for aquariums. Background Technology
[0002] Maintaining clean aquarium water is crucial in ornamental fish keeping. Fish waste and food scraps, if not removed promptly, not only affect the aquarium's appearance but, more importantly, lead to water quality deterioration, threatening the fish's health. Traditional aquarium cleaning relies heavily on regular manual cleaning, which is time-consuming, labor-intensive, and ineffective in real-time filtration. With technological advancements, various aquarium filtration devices have emerged on the market, designed to automatically and efficiently handle fish waste and particulate matter. One example is the commonly used rotary drum microfiltration system.
[0003] A rotary drum microfilter mainly consists of a rotating stainless steel drum. The drum is connected to a motor via gears or other transmission mechanisms, and the motor drives its rotation. To maintain the cleanliness of the screen and filtration efficiency, rotary drum microfilters are usually equipped with a backwashing system. The working principle is as follows: wastewater or the liquid to be filtered is introduced into the drum. During the drum's rotation, the liquid flows outward through the screen, while solid particles or suspended matter are trapped inside the screen. When the accumulated solid particles or suspended matter on the screen reaches a certain level, the backwashing system starts working. The backwash pump draws filtered effluent or other clean water and sprays it onto the screen through nozzles. The flushing water is sprayed from the outside of the screen inward, washing away the particulate matter adhering to the screen. The washed-off particulate matter is collected in a backwash water collection tank and discharged from the equipment through a drain pipe, while the filtered clean water is pumped away.
[0004] Rotary drum microfilters achieve solid-liquid separation through a rotating drum, offering advantages such as high filtration efficiency, large processing capacity, and stable operation. However, when directly applying rotary drum microfilters to home aquarium filtration, they often suffer from problems such as large size, high energy consumption, and complex installation, resulting in poor adaptability and difficulty in meeting diverse consumer needs. Furthermore, the rotating drum is prone to clogging during use, requiring frequent cleaning, increasing operating and time costs. Additionally, wastewater is generated during filtration and rinsing, which is typically discharged directly, leading to water waste.
[0005] To address the shortcomings of existing technologies, this invention proposes a novel fish waste and particulate matter filtration device for aquariums. Through a unique modular design, this device achieves efficient and convenient filtration. Utility Model Content

[0034] Implementation examples, by Figure 1-9 Provided is a fish waste and particulate matter filtration device for aquariums, comprising:
[0035] The top cover 1 has a frame 11 fixed to its top edge. A diverter head 13 is fixed in the middle of the top cover 1. Three sets of inclined nozzles 132 are fixedly connected to the outside of the diverter head 13. A water outlet groove 1321 is opened at the bottom of each set of inclined nozzles 132 and communicates with the inside. A connecting pipe port 131 is also fixedly connected to the outside of the diverter head 13. A water supply pipe 12 is inserted into the connecting pipe port 131 and extends through the side end of the top cover 1.
[0036] The filter body box 2 has a slot 21 on the top of the filter body box 2 that is adapted to connect with the slot frame 11 of the upper cover 1. A surrounding plate 23 is fixed in the middle of the filter body box 2. A through groove 24 is opened in the middle of the surrounding plate 23, which passes through the filter body box 2. A connecting post 25 is fixed in the middle of the through groove 24 in the middle of the filter body box 2. A connector 251 is fixed on the top of the connecting post 25. A filter structure 22 is installed through the connector 251. Two discharge holes 26 are opened on both sides of the bottom of the filter body box 2 outside the surrounding plate 23.
[0037] The drawer outer box 3 has a card frame 31 fixed on the top outer edge of the drawer outer box 3, which is adapted to connect with the bottom of the filter body box 2. The bottom inner side of the drawer outer box 3 is fixed with a limiting frame 33, and the middle of the drawer outer box 3 is fixed with a rectangular frame 32. The front of the drawer outer box 3 has two through slots, through which two filter drawers 5 are inserted and installed and contact the rectangular frame 32. Each filter drawer 5 has a filter cotton 51 embedded inside.
[0038] The bottom support 4 has a card frame 3 41 fixed on the outer edge of the top of the bottom support 4, which is adapted to the bottom of the drawer outer box 3. The bottom center of the bottom support 4 has a connecting hole 42.
[0039] Specifically, the device is relatively small overall, occupies little space, is suitable for aquariums of different sizes, and is modularly assembled, making it easy to install, disassemble, and clean. Parts can be easily replaced if damaged later. In use, the wastewater pump draws the mixture of fish feces and sediment particles from the bottom of the aquarium and delivers it to the diverter head 13. The water from the outlet channels 1321 of the three sets of inclined nozzles 132 sprays out at an angle, hitting the filter structure 22. The water is filtered through the filter screen 221, intercepting fish feces and particulate impurities. The filtered water enters the conduit 23 and flows downwards through the through-channel 24, passing through the rectangular frame 32 into the confluence base 4, where it converges and then flows back into the aquarium through the confluence drain hole 42. Because the mounting bracket 222 for fixing the filter screen 221 is connected to the connector 251 of the connecting column 25 via the mounting bearing 223, the mounting bracket 222... The filter can rotate, with the three sets of tilting nozzles 132 spraying water at an angle onto the filter screen 221, providing power to make the filter screen 221 rotate. During the rotation, the filtered fish feces, particulate impurities, and a small amount of water are thrown out and fall into the bottom of the filter body box 2. Combined with the flushing effect of the tilting water, this effectively prevents the filter screen 221 from clogging and greatly improves the filtration effect. The mixed fish feces, particulate impurities, and a small amount of water accumulate and are discharged through the two discharge holes 26 into the two filter drawers 5. The filter cotton 51 in the filter drawers 5 performs secondary filtration, intercepting fish feces and particulate impurities. The filtered water passes through the filter cotton 51 and falls into the confluence base 4, then flows back into the fish tank from the confluence drain hole 42, realizing the full recycling of water resources and reducing waste.
[0040] In this embodiment, the bottom of the confluence base 4 can be fixedly mounted with a bracket, and the confluence base 4 is placed on the top of the fish tank through the bracket; this facilitates installation and use.
[0041] In this embodiment, the water supply pipe 12 is connected to the output end of the external sludge pump. The external sludge pump is installed at the bottom of the fish tank to extract fish feces and sediment particles. The sewage pump is controlled to extract the water-liquid mixture of fish feces and sediment particles from the bottom of the fish tank and transport it to the device for filtration.
[0042] In this embodiment, the three sets of tilted nozzles 132 are tilted in the same direction, and the water sprayed from the water outlet 1321 is also tilted. The water outlet 1321 of the three sets of tilted nozzles 132 tilts and sprays the tilted water onto the filter screen 221, providing power for the filter structure 22.
[0043] In this embodiment, the filter structure 22 includes a mounting frame 222, a filter screen 221 is fixed on the top of the mounting frame 222, and a mounting bearing 223 is fixed at the bottom of the mounting frame 222. The outer ring of the mounting bearing 223 is fixed to the mounting frame 222, and the inner ring is embedded and connected to the connector 251.
[0044] Specifically, since the mounting bracket 222 that fixes the filter screen 221 is connected to the connector 251 of the connecting column 25 through the mounting bearing 223, the mounting bracket 222 can rotate. The water outlet 1321 of the three sets of inclined nozzles 132 sprays inclined water onto the filter screen 221, providing power to the filter screen 221, thereby driving the filter screen 221 to start rotating. During the rotation, the filtered fish feces, particulate impurities and a small amount of water are thrown out and fall into the bottom of the filter body box 2. With the flushing of the inclined water, the filter screen 221 is effectively prevented from clogging and the filtration effect is greatly improved.
[0045] In this embodiment, a baffle net 52 is fixed at the bottom of the filter drawer 5, and the two filter drawers 5 correspond to the two discharge holes 26 respectively. Mixed fish feces, particulate impurities and a small amount of water are discharged through the two discharge holes 26 and fall into the two filter drawers 5. The filter cotton 51 in the filter drawer 5 performs secondary filtration to intercept fish feces and particulate impurities. The filtered water passes through the filter cotton 51 and falls into the confluence base 4 to collect.
[0046] In this embodiment, the through cavity inside the rectangular frame 32 corresponds to and cooperates with the through groove 24. The filtered water flows downward through the through groove 24, passes through the rectangular frame 32, and enters the confluence base 4 to converge.
[0047] Working principle:
[0048] During installation, the confluence base 4 is placed on top of the aquarium via a bracket. The drawer outer box 3 is then inserted into the upper limit of the card frame 41. At the same time, the two filter drawers 5 are inserted into the connecting slots into the drawer outer box 3. The filter main body box 2 is then inserted into the card frame 31 and limited. Finally, the upper frame card frame 11 is engaged with the card slot 21 of the filter main body box 2, thus forming the filter assembly. This device is relatively small and occupies little space. It is suitable for aquariums of different sizes and is modularly assembled, making it easy to install, disassemble, and clean. It is also easy to replace parts in case of partial damage later.
[0049] During operation, the sewage pump draws the mixture of fish feces and sediment particles from the bottom of the aquarium and delivers it to the diversion head 13. The water outlet 1321 of the three sets of inclined nozzles 132 sprays out at an angle and onto the filter structure 22. The water is filtered through the filter screen 221, which intercepts the fish feces and particulate impurities in the water. The filtered water enters the surrounding plate 23 and flows downward through the through groove 24, through the rectangular frame 32, and into the confluence base 4. It then flows back into the aquarium from the confluence drain hole 42.
[0050] Since the mounting bracket 222 that fixes the filter screen 221 is connected to the connector 251 of the connecting column 25 through the mounting bearing 223, the mounting bracket 222 can rotate. The water outlet 1321 of the three sets of inclined nozzles 132 sprays inclined water onto the filter screen 221, providing power to the filter screen 221, thereby driving the filter screen 221 to start rotating. During the rotation, the filtered fish feces, particulate impurities and a small amount of water are thrown out and fall into the bottom of the filter body box 2. With the flushing of the inclined water, the filter screen 221 is effectively prevented from clogging and the filtration effect is greatly improved.
[0051] As fish feces, particulate impurities, and a small amount of water accumulate, they are discharged through two discharge holes 26 and fall into two filter drawers 5. The filter cotton 51 in the filter drawer 5 performs secondary filtration, intercepting fish feces and particulate impurities. The filtered water passes through the filter cotton 51 and falls into the confluence base 4, where it is collected and then flows back into the fish tank through the confluence drain hole 42, thus achieving full recycling of water resources and reducing waste.
[0052] Later, filter drawer 5 can be pulled out to pour out the collected fish feces and particulate impurities, and the cleaning cotton can be washed and reused.
