Description

Technical Field

[0001] The invention relates to the technical field of fish tank accessories, and in particular to a fish feces and particle filtering device for a fish tank. Background Art

[0002] In the process of ornamental fish farming, it is crucial to keep the water in the fish tank clean. If particulate matter such as fish feces and food residues are not cleaned in time, it will not only affect the aesthetics of the fish tank, but more importantly, it will cause the water quality to deteriorate and pose a threat to the health of the fish. Traditional fish tank cleaning methods mostly rely on manual regular cleaning, which is not only time-consuming and labor-intensive, but also difficult to achieve real-time and effective filtration and purification. With the development of technology, various fish tank filtration devices have appeared on the market, which are designed to automatically and efficiently handle fish feces and particulate matter in the fish tank. Such as the commonly used rotary drum microfiltration machine on the market.

[0003] The rotary drum microfilter mainly consists of a rotatable stainless steel drum (drum), which is connected to the motor through gears or other transmission mechanisms and driven by the motor to rotate. In order to keep the screen clean and the filtering efficiency, the rotary drum microfilter is usually equipped with a backwashing system. The working principle is: sewage or liquid to be filtered is introduced into the drum. During the rotation of the drum, the liquid flows outward through the screen, while solid particles or suspended matter are trapped inside the screen. When the solid particles or suspended matter accumulated on the screen reaches a certain level, the backwashing system starts to work, and the backwashing pump extracts the filtered water or other clean water source, and washes the screen through the nozzle. The flushing water is sprayed from the outside of the screen to the inside, and the particulate matter attached to the screen is washed off. The washed off particulate matter is collected in the backwashing water collection tank and discharged from the equipment through the sewage pipe, and the filtered clean water is pumped away by the pump.

[0004] The rotary drum microfilter achieves solid-liquid separation through a rotating drum, and has the advantages of high filtration efficiency, large processing capacity, and stable operation. However, when the rotary drum microfilter is directly applied to household fish tank filtration, it often has problems such as large size, high energy consumption, and complex installation. It has poor adaptability and is difficult to meet the diverse needs of consumers. The rotating drum is prone to clogging during use and requires frequent cleaning, which increases the cost and time cost of use. In addition, some sewage will be generated during the filtration and flushing process, and the sewage is generally discharged directly, resulting in a waste of water resources.

[0005] In view of the shortcomings of the prior art, the present invention proposes a novel fish feces and particulate matter filtering device for a fish tank. The device realizes efficient and convenient filtering functions through a unique modular design. Summary of the invention

[0038] Specifically, the device is relatively small as a whole, occupies little space, is suitable for fish tanks of different sizes, and is modularly assembled, easy to install and disassemble, easy to clean, and easy to replace parts in case of local damage in the later stage. When in use, the sewage pump is controlled to extract the water mixture of fish feces and precipitated particles at the bottom of the fish tank and transport it to the diverter head 13. The outlet troughs 1321 of the three groups of inclined nozzles 132 are tilted to spray, spray on the filter structure 22, and are filtered through the filter screen 221 to intercept fish feces and particulate impurities in the water. The filtered water enters the surrounding plate 23, and goes downward through the through groove 24, passes through the rectangular frame 32, enters the confluence bottom support 4, and converges, and then flows back into the fish tank from the confluence hole 42; because the mounting frame 222 fixed with the filter screen 221 is connected to the joint 251 of the connecting column 25 through the mounting bearing 223, the mounting frame 222 It can rotate, and the water outlet trough 1321 of the three groups of inclined nozzles 132 tilts and sprays inclined water onto the filter screen 221, providing power for the filter screen 221, thereby driving the filter screen 221 to start rotating, and the filtered fish feces, particulate impurities and a small amount of water are thrown out and separated during the rotation, and fall into the bottom of the filter main body box 2, and cooperate with the flushing of the inclined water, thereby effectively preventing the filter screen 221 from being blocked, and greatly improving the filtering effect; the mixed fish feces, particulate impurities and a small amount of water are discharged through the two discharge holes 26 as they accumulate and fall into the two filter drawers 5, and are filtered twice through the filter cotton 51 in the filter drawer 5 to intercept fish feces and particulate impurities. The filtered water passes through the filter cotton 51 and falls into the confluence bottom support 4 for convergence, and then flows back into the fish tank from the confluence hole 42, thereby realizing the full recycling of water resources and reducing waste.

[0039] In this embodiment, the bottom of the confluence bottom bracket 4 can be fixed with a mounting bracket, and the confluence bottom bracket 4 is placed on the top of the fish tank through the bracket, which is convenient for installation and use.

[0040] In this embodiment, the water pipe 12 is installed with a hose connected to the output end of an external sewage suction pump, and the external sewage suction 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 at the bottom of the fish tank and transport it to the device for filtration.

[0041] In this embodiment, the three groups of inclined nozzles 132 are inclined in the same direction, and the water liquid sprayed from the water outlet trough 1321 is also inclined. The water outlet trough 1321 of the three groups of inclined nozzles 132 sprays the inclined water liquid onto the filter net 221 to provide power for the filter structure 22.

[0042] In this embodiment, the filtering structure 22 includes a mounting frame 222 , a filter screen 221 is fixed on the top of the mounting frame 222 , a mounting bearing 223 is fixed on 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 inlaid and connected with the joint 251 .

[0043] Specifically, since the mounting frame 222 on which the filter 221 is fixed is connected to the joint 251 of the connecting column 25 through the mounting bearing 223, the mounting frame 222 can rotate, and the water outlet troughs 1321 of the three groups of inclined nozzles 132 tilt to spray inclined water onto the filter 221, providing power for the filter 221, thereby driving the filter 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 main body box 2, and cooperate with the flushing of the inclined water, thereby effectively preventing the filter 221 from being blocked, thereby greatly improving the filtering effect.

[0044] In this embodiment, a blocking 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. The 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 filtered water passes through the filter cotton 51 and falls into the confluence bottom support 4 for convergence.

[0045] In this embodiment, the internal through cavity of the rectangular frame 32 corresponds to the through groove 24 , and the filtered water flows downward through the through groove 24 , passes through the rectangular frame 32 , and enters the converging bottom support 4 to be gathered.

[0046] Working principle:

[0047] During installation, the confluence bottom bracket 4 is placed at the top of the fish tank through the bracket, the drawer outer box 3 is inserted into the upper limit position of the card frame 3 41, and the two filter drawers 5 are inserted into the connecting groove into the drawer outer box 3, and then the filter main body box 2 is inserted into the bag card frame 2 31 to limit the position, and finally the upper frame card frame 11 and the card slot 1 21 of the filter main body box 2 are connected to limit the position, so as to combine into a filter as a whole. The device is relatively small as a whole, occupies less space, is suitable for fish tanks of different sizes, and is modularly assembled, easy to install and disassemble, easy to clean, and convenient to replace parts in case of local damage in the later stage;

[0048] When working, the sewage pump is controlled to extract the mixture of fish excrement and precipitated particles at the bottom of the fish tank, and transport it to the diverter head 13. The water outlet slots 1321 of the three groups of inclined nozzles 132 are inclined to spray, and spray on the filter structure 22. The water is filtered through the filter net 221 to intercept the fish excrement and particle impurities in the water. The filtered water enters the surrounding plate 23, and flows downward through the through groove 24, passes through the rectangular frame 32, enters the confluence bottom support 4, and then flows into the fish tank again from the confluence hole 42.

[0049] Since the mounting frame 222 to which the filter 221 is fixed is connected to the joint 251 of the connecting column 25 via the mounting bearing 223, the mounting frame 222 can rotate, and the water outlet troughs 1321 of the three groups of inclined spray heads 132 tilt and spray inclined water onto the filter 221, providing power for the filter 221, thereby driving the filter 221 to start rotating. During the rotation process, the filtered fish feces, particulate impurities and a small amount of water are thrown out and fall into the bottom of the filter main body box 2, and cooperate with the flushing of the inclined water, thereby effectively preventing the filter 221 from being blocked, and greatly improving the filtering effect;

[0050] The mixed fish excrement, particulate impurities and a small amount of water are discharged through the two discharge holes 26 and fall into the two filter drawers 5 as they accumulate, and the filter cotton 51 in the filter drawer 5 performs secondary filtration to intercept the fish excrement and particulate impurities. The filtered water passes through the filter cotton 51 and falls into the confluence bottom support 4 to gather, and then flows back into the fish tank from the confluence hole 42, thereby realizing the full recycling of water resources and reducing waste.

[0051] At a later stage, the filter drawer 5 can be pulled out, the collected fish feces and granular impurities can be poured out, and the cleaning cotton can be cleaned and reused.
