Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of aquarium, especially relates to a fish excrement sedimentation collector and a sedimentation adsorption aquarium. BACKGROUND

[0002] Prior art:

[0003] With the improvement of people's living standards, more and more people like to raise fish and plant flowers. Aquaculture of ornamental fish in an aquarium is the most popular method. The space of the aquarium is small and many fish are raised, and the feces of the fish are broken, which pollutes the water quality. Moreover, due to the large flow of the circulating water in the aquarium, the fish excrement and sundries are too much, and high-density filter materials cannot be used for filtration.

[0004] At present, the methods for solving the problem of fish excrement collection in the aquarium in the prior art mainly include: collecting fish excrement by filtration, or using a filter box or a dry-wet separation box.

[0005] The method of collecting fish excrement by filtration has the following problems: if the internal gap of the filter material is large, the small sundries can easily pass through the filter material. If the internal gap of the filter material is small, the fish excrement blocked by the filter material is continuously washed by water, and the fish excrement is easily broken, which can release and dissolve organic matter, viruses of sick fish and small sundries suspended matter into water. The consequences are that the fish excrement is broken and pollutes the water quality, and the fish excrement and residues are cleaned, and the water is polluted.

[0006] The method of using a filter box or a dry-wet separation box has the following problems: the flow rate of water in the box is too fast, and the nitrifying bacteria in the gap of the filter material are difficult to adsorb the small sundries suspended matter.

[0007] At the same time, the methods of collecting fish excrement by filtration or using a filter box or a dry-wet separation box need to use a submersible pump. If the submersible pump is used to pump water into the upper fish tank to drive the water circulation and flow to collect fish excrement, the following problems exist: on the one hand, the water flow is fast, the feces is easily broken, and the water quality is polluted; on the other hand, the submersible pump has the disadvantages of high lift, large flow, large power, up and down circulation, loud noise and high power consumption.

[0008] In summary, the biggest disadvantage of the aquarium is that the fish excrement is broken and pollutes the water quality, and the two methods of the aquarium are the main causes of the breaking of the fish excrement. 1. The fish excrement is broken and pollutes the water quality in the process of flowing and colliding from the upper tank to the lower tank. 2. The fish excrement is broken and pollutes the water quality when the fish excrement is blocked by the filter and the water continuously washes the fish excrement.

[0009] The difficulty and significance of solving the above technical problems:

[0010] Therefore, based on these problems, it has important practical significance to provide a fish excrement sedimentation collector and a sedimentation adsorption aquarium. SUMMARY

[0011] The purpose of this application is to provide a fish waste sedimentation collector and a sedimentation adsorption aquarium to solve the technical problems in the prior art.

[0012] The technical solution adopted in this application embodiment to solve the technical problems existing in the prior art is as follows:

[0013] A fish waste settling collector is installed on an aquarium. The fish waste settling collector includes a settling tank, and the bottom of the settling tank has a settling tank inlet and a main water inlet. The lower edge of the settling tank inlet is flush with the bottom of the aquarium, and the main water inlet is located above the settling tank inlet. Water entering the main water inlet flows upward along the side wall and guide plate of the fish waste settling collector.

[0014] The embodiments of this application may also employ the following technical solutions:

[0015] In the aforementioned fish waste settling collector, the main inlet of the collector is further described as having an outlet at the end, and the outlet is located above the settling tank.

[0016] In the aforementioned fish waste settling collector, furthermore, the lower edge of the waste inlet of the settling tank is a fish waste storage platform for the settling tank, and the lower edge of the fish waste storage platform for the settling tank is flush with the bottom of the aquarium.

[0017] Above the inlet of the settling tank is an inlet support platform, which is positioned opposite to the fish waste storage platform of the settling tank, forming a channel with an equal cross-section along the water flow direction.

[0018] In the above-mentioned fish waste settling collector, the settling tank is further divided into an upper settling tank and a lower settling tank by a partition hole cover plate. The upper settling tank and the lower settling tank are connected by a cleaning installation partition port and a water outlet of the lower settling tank. The partition hole cover plate covers the cleaning installation partition port.

[0019] Below the partition hole cover plate is a sinking trough agitator plate. The partition hole cover plate and the sinking trough agitator plate are connected and fixed by a cover plate agitator plate connecting rod. The cover plate agitator plate connecting rod is sleeved on the overflow pipe and can move up and down along the overflow pipe. A forced discharge hole is opened at the bottom of the sinking trough.

[0020] In the aforementioned fish waste settling collector, the settling tank is further divided into an upper settling tank and a lower settling tank by a settling tank water flow brush. A settling tank agitator is provided below the settling tank water flow brush. The settling tank water flow brush and the settling tank agitator are connected by an agitator rod. The agitator rod is sleeved on the overflow pipe and can move up and down along the overflow pipe.

[0021] In the aforementioned fish waste settling collector, the settling tank sidewall is further provided with a water flow control brush, which is divided into two groups and respectively set on two adjacent sidewalls of the fish waste settling collector.

[0022] A sedimentation aquarium, wherein the sedimentation aquarium is equipped with a fish waste sedimentation collector as described above, and the waste inlet of the sedimentation tank and the main water inlet of the collector are located on two side plates of the fish waste sedimentation collector.

[0023] In the aforementioned sedimentation and adsorption aquarium, furthermore, the fish waste sedimentation collector has at least two sedimentation trough flow rate adjustment holes on its side wall.

[0024] A propeller pump is installed on the side wall of the fish waste sedimentation collector, and the propeller pump is located below the water level line of the aquarium.

[0025] The side wall of the fish waste sedimentation collector has comb holes for draining oily substances, and the water level line of the aquarium is located between the upper and lower edges of the comb holes for draining oily substances.

[0026] In the aforementioned sedimentation and adsorption aquarium, the overflow outlet of the aquarium's overflow pipe is connected to the biochemical adsorption tank, the biochemical adsorption tank and the biochemical tank are connected, the submersible pump delivers the water from the biochemical tank to the end of the submersible pump's outlet pipe, the end of the submersible pump's outlet pipe and the fish waste sedimentation collector are located at both ends of the aquarium, and the overflow inlet of the overflow pipe is located inside the fish waste sedimentation collector.

[0027] A method for collecting fish feces by sedimentation, the method comprising the following steps: using the fish feces sedimentation collector described in any of the above claims.

[0028] One or more technical solutions provided in the embodiments of this application have at least the following beneficial effects:

[0029] 1. This invention does not use filtration to collect fish waste, preventing it from flowing into the overflow pipe and down to the lower tank. This solves the main problem of fish waste breaking and polluting the water. The invention uses a sedimentation tank to collect waste, and the bottom of the fish waste sedimentation collector has a sedimentation tank inlet and a main water inlet. Most of the circulating water in the fish tank enters the main water inlet, only serving to push the fish waste towards the sedimentation tank inlet without entering the sedimentation tank itself. Only a small amount of flowing water and fish waste enters the sedimentation tank through the inlet. This quickly draws the fish waste to the inlet without sucking it into the main water inlet. Using a sedimentation tank to collect fish waste maintains its original shape, preventing breakage and water pollution.

[0030] 2. This invention employs a two-stage separation of fish waste and flowing water. The first separation utilizes the principle that fish waste flows along with the water at the bottom of the aquarium, separating the fish waste from most of the flowing water before it enters the settling tank. Only a small amount of flowing water and fish waste enter the settling tank. The second settling separation of fish waste and flowing water occurs when the upward flow velocity of the water in the settling tank is lower than the settling velocity of the fish waste, causing the fish waste to settle.

[0031] 3. The fish waste storage platform in the settling tank of this invention forms a fish waste storage area where the water is almost still. Because an evenly spaced fish waste channel is formed between the auxiliary platform at the inlet and the fish waste storage platform in the settling tank, fish waste entering the settling tank inlet quickly passes over the fish waste storage platform and enters the settling area, settling into the fish waste storage area. Simultaneously, the height of the fish waste storage platform is higher than the upper edge of the settling tank inlet, facilitating upward and oblique water flow.

[0032] 4. The height of the main inlet of the collector in this invention from the bottom of the fish tank is between 2cm and 12cm. If the main inlet of the collector is too high from the bottom of the fish tank, fish waste will stay in front of the waste inlet of the sedimentation tank for a longer time. If the main inlet of the collector is too close to the bottom of the fish tank, fish waste will be sucked in by the main inlet.

[0033] 5. The submersible pump outlet pipe end and the propeller pump of the present invention are located at both ends of the aquarium. The two work together to promote the circulation of water in the aquarium. This can reduce the power of the submersible pump. Only a very small power propeller pump needs to be installed above the aquarium.

[0034] 6. The cross-sectional area of ​​the settling tank of the present invention is 15 to 40 times the cross-sectional area of ​​the settling tank inlet, thereby reducing the upward flow velocity of water in the settling tank. The settling tank is divided into three regions according to the water flow velocity: a straight flow region between the settling tank inlet and the lower settling tank outlet, a fish waste storage region behind the fish waste storage platform in the settling tank where the water is almost still, and a settling region (the area of ​​the settling tank after removing the straight flow region and the fish waste storage region).

[0035] 7. The main parts of the lower and upper settling tanks of the present invention are settling areas. The upper settling tank is the space between the main inlet outlet of the collector and the cover plate of the baffle hole. The main function of the upper settling tank is to settle the feces coming out of the main inlet outlet of the collector.

[0036] 8. The partition hole cover plate and the sinking trough agitator plate of the present invention are connected and fixed by the cover plate agitator plate connecting rod. The three are integrated and are fitted over the overflow pipe. They can slide up and down and can also be easily removed. When defecating, the cover plate agitator plate connecting rod is slid up and down to agitate the fish waste that has settled in the fish waste storage area and discharge it together with the water.

[0037] 9. This invention uses a water flow control brush in the settling tank to solve the problem of water rushing upwards, while also adsorbing some tiny suspended solids. Furthermore, the distance between the end of the water flow control brush and the side wall of the fish waste settling collector is 0.45-0.55 cm to prevent the brush from being clogged by nitrifying bacteria, thus preventing water from flowing upwards.

[0038] 10. The present invention uses a water flow control brush, which solves the problem of water gushing upwards while avoiding the problem of uneven brush distribution. Attached Figure Description

[0054] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0055] Example 1

[0056] In this embodiment, the fish waste settling collector is installed on an aquarium. The fish waste settling collector includes a settling tank. The fish waste settling collector has a settling tank inlet 1 and a collector main inlet 2 at the bottom of the settling tank. The lower edge of the settling tank inlet 1 is flush with the bottom of the aquarium. The collector main inlet 2 is located above the settling tank inlet 1. The water entering the collector main inlet 2 flows upward along the side wall 22 and guide plate 21 of the fish waste settling collector.

[0057] The technical solution described in this embodiment has at least the following technical effects or advantages:

[0058] This embodiment uses a sedimentation tank to collect fish waste. The fish waste sedimentation collector has a sedimentation tank inlet and a main water inlet at the bottom. Most of the circulating water in the fish tank enters the main water inlet of the collector, only serving to push the fish waste towards the sedimentation tank inlet without entering the sedimentation tank itself. Only a small amount of flowing water and fish waste enters the sedimentation tank through the inlet. This quickly draws the fish waste to the inlet without sucking it into the main water inlet. Using a sedimentation tank to collect fish waste maintains its original shape, preventing breakage and water pollution.

[0059] This embodiment uses sedimentation to collect fish waste, the biggest advantage of which is that the fish waste is not broken up and does not pollute the water. Because the fish waste needs to flow at the bottom of the aquarium, a large overall circulation flow rate is required, needing a large flow of water to propel the fish waste towards the inlet, and this large flow of water cannot enter the sedimentation tank. This embodiment has a sedimentation tank inlet 1 and a main inlet 2 at the bottom of the fish waste sedimentation collector. Since the flow rates at sedimentation tank inlet 1 and main inlet 2 are equal, and the fish waste flows at the very bottom of the aquarium, the fish waste, along with a small amount of flowing water, enters sedimentation tank inlet 1 and flows into the sedimentation tank. The main inlet 2 uses a large flow of water to propel the fish waste in the aquarium towards sedimentation tank inlet 1, and also only draws in water flowing above the fish waste. The water entering the main inlet 2 flows into the fish waste sedimentation collector above the sedimentation tank. The fish waste separates from most of the flowing water, creating conditions for the next step of sedimentation collection.

[0060] This embodiment uses sedimentation adsorption to collect fish waste and dissolved impurities and suspended matter in the water, preventing fish waste from entering the overflow pipe and flowing into the lower tank. Because the circulating water in the upper tank of the aquarium has a certain flow rate, the fish waste will move towards the waste inlet 1 of the sedimentation tank, and such a large amount of flowing water cannot enter the sedimentation tank. This embodiment utilizes the principle of fish waste flowing at the bottom of the aquarium. Most of the circulating water carries the fish waste to the waste inlet 1 of the sedimentation tank, where it separates from the fish waste and enters the main inlet 2 of the collector, flowing into the fish waste sedimentation collector above the sedimentation tank. A small amount of flowing water and fish waste enters the sedimentation tank, increasing the space. The water flow rate is lower than the fish waste settling speed, causing the fish waste to settle to the fish waste storage area behind the storage platform.

[0061] Example 2

[0062] Based on Embodiment 1, the end of the main inlet of the collector is the main inlet outlet 5 of the collector. In order to prevent water from the main inlet 2 of the collector from entering the settling tank, the main inlet outlet 5 of the collector is located above the settling tank; the height of the main inlet of the collector from the bottom of the fish tank is more than 2cm and less than 12cm.

[0063] The main inlet 2 of the collector, the main inlet outlet 5 of the collector, and the inlet 1 of the settling tank are all rectangular holes.

[0064] The technical solution described in this embodiment has at least the following technical effects or advantages:

[0065] Since the main inlet and outlet 5 of the collector is located above the settling tank, the water entering the main inlet 2 of the collector flows upward along the side wall 22 and guide plate 21 of the fish waste settling collector and enters the upper part of the fish waste settling collector. This creates conditions for the settling and collection of fish waste through the settling tank, allowing most of the flowing water to separate from the fish waste.

[0066] Example 3

[0067] Based on Embodiment 1, the lower edge of the sedimentation tank inlet 1 is a sedimentation tank fish waste storage platform 3. The sedimentation tank fish waste storage platform 3 has a structure that is narrow at the top and wide at the bottom, with a height between 1cm and 1.5cm. The lower edge of the sedimentation tank fish waste storage platform 3 is flush with the bottom of the aquarium. Behind the sedimentation tank fish waste storage platform 3, a fish waste storage area with almost no water flow is formed.

[0068] Above the inlet 1 of the settling tank is an inlet booster platform 4, which is positioned opposite the fish waste storage platform 3 of the settling tank, forming a channel with an equal cross-section along the water flow direction. This allows fish waste to quickly cross the fish waste storage platform 3 of the settling tank and settle into the fish waste storage area.

[0069] The technical solution described in this embodiment has at least the following technical effects or advantages:

[0070] Behind the fish waste storage platform 3 in the settling tank, a fish waste storage area with almost no water flow is formed. Because an evenly spaced fish waste channel is formed between the auxiliary platform 4 at the inlet and the fish waste storage platform 3, fish waste entering the settling tank inlet 1 quickly passes over the fish waste storage platform 3 and enters the settling area, settling into the fish waste storage area. Simultaneously, the height of the fish waste storage platform 3 is higher than the upper edge of the settling tank inlet 1, facilitating upward and diagonal water flow.

[0071] Because the sedimentation tank inlet storage platform 3 has a certain height, a fish waste storage area with almost no water flow is formed behind it. Since an evenly spaced fish waste channel is formed between the auxiliary platform 4 at the inlet and the sedimentation tank storage platform 3, and the water flow rate at the sedimentation tank inlet 1 is fast, when fish waste approaches the inlet 1, it is sucked into the fish waste channel and quickly passes over the sedimentation storage platform 3, settling into the fish waste storage area behind the platform 3. It is then discharged during defecation.

[0072] Example 4

[0073] Based on Embodiment 1, the settling tank is divided into an upper settling tank 16 and a lower settling tank 15 by a partition hole cover plate 12. The upper settling tank 16 and the lower settling tank 15 are connected by a cleaning installation partition port 18 and a water outlet 17 of the lower settling tank. The partition hole cover plate 12 covers the cleaning installation partition port 18. The cross-sectional area of ​​the settling tank is 15 to 40 times the cross-sectional area of ​​the settling tank inlet.

[0074] Below the partition hole cover plate 12, there is a sinking trough agitator plate 13. The partition hole cover plate 12 and the sinking trough agitator plate 13 are connected and fixed by a cover plate agitator plate connecting rod 14. The cover plate agitator plate connecting rod 14 is sleeved on the overflow pipe 11 and the cover plate agitator plate connecting rod 14 can move up and down along the overflow pipe 11. The bottom of the sinking trough 15 has a forced discharge hole 19.

[0075] Specifically, as shown in the instruction manual Figures 1-3 As shown, this embodiment includes:

[0076] Sinking tank inlet 1: Fish waste flows at the bottom of the aquarium. Sinking tank inlet 1 is located at the very bottom of the aquarium and collects the fish waste flowing from the bottom of the aquarium.

[0077] Main inlet 2 of the collector: The water entering the fish waste settling collector mainly enters through the main inlet 2 of the collector. The main inlet 2 of the collector is located above the waste inlet 1 of the settling tank, 2cm to 12cm away from the bottom of the fish tank. In this way, the fish waste is quickly sucked to the waste inlet 1 of the settling tank, but is not allowed to enter the main inlet 2 of the collector.

[0078] Settling tank fish waste storage platform 3: A settling tank fish waste storage platform 3 is provided at the inlet 1 of the settling tank. Its height is between 1cm and 1.5cm. A fish waste storage area with almost no water flow is formed behind the settling tank fish waste storage platform 3.

[0079] The inlet assist platform 4 is set opposite to the fish waste storage platform 3 in the settling tank, forming an equally spaced channel between the two. This allows the fish waste to quickly cross the fish waste storage platform 3 in the settling tank and settle into the fish waste storage area.

[0080] Collector main inlet outlet 5: To prevent water from collector main inlet 2 from entering the settling tank, collector main inlet outlet 5 should be located above the settling tank.

[0081] Settling tank flow rate adjustment hole 6: Increase or decrease the number of holes in the settling tank flow rate adjustment hole 6 to adjust the flow rate of water in the settling tank.

[0082] Propeller pump 7: Propeller pump 7 is located at the overflow pipe inlet 9. It drains the water in the settling tank, promotes the circulation of water in the aquarium, and drives fish waste into the settling tank inlet 1. Most of the water flows into the collector main inlet 2.

[0083] Submersible pump outlet pipe 8: Connects the submersible pump 23 through the sedimentation tank and overflow pipe 11, pumping the water from the biological tank 24 into the fish tank.

[0084] Overflow pipe inlet 9: Water above the overflow pipe inlet 9 flows into the overflow pipe inlet 9.

[0085] Overflow pipe outlet 10: Water flows out of the overflow pipe 11, and the pipe wall collides with the water to increase oxygen.

[0086] Overflow pipe 11: The water in overflow pipe 11 collides with the pipe wall to increase oxygen.

[0087] Partition hole cover 12: Covers the cleaning and installation partition opening 18, which is opened during defecation and cleaning.

[0088] Sinking trough agitator 13: Stirs the sinking trough 15 during defecation.

[0089] Cover plate agitator rod 14: When defecating, pull the cover plate agitator rod 14 to swing up and down, so that the fish waste that has settled in the lower settling tank 15 and the upper settling tank 16 can be suspended and discharged.

[0090] Settling Tank 15: The water flow within the settling tank 15 is divided into three zones: a straight-line flow zone between the settling tank inlet 1 and the settling tank outlet 17; a settling zone (including the main parts of the settling tank 15 and the upper settling tank 16, where the upper settling tank 16 extends from the collector's main inlet outlet to the baffle cover 12; the function of the upper settling tank 16 is to settle the feces exiting from the collector's main inlet outlet); and a fish waste storage zone. The upward flow speed of water within the settling tank 15 is lower than the settling speed of the fish waste.

[0091] Upper settling tank 16: collects, settles, and stores fish waste. The upward flow of water in the upper settling tank 16 is slower than the settling speed of the fish waste.

[0092] Water outlet 17 in the settling tank: Water that has overflowed from the settling tank 15 flows out.

[0093] Cleaning installation partition opening 18: facilitates the installation of overflow pipe 11, forced drainage hole 19 and cleaning sink 15.

[0094] Forced drainage hole 19: Used for drainage and defecation.

[0095] Oil-draining comb hole 20: This drains oily substances floating on the surface of the aquarium and blocks fish food. The width of the oil-draining comb hole 20 is between 0.1cm and 0.2cm.

[0096] Guide plate 21: Water entering the main inlet 2 of the collector flows upward along the side wall 22 of the fish waste collector and the guide plate 21.

[0097] Fish waste settling collector sidewall 22: The fish waste settling collector sidewall 22 near the fish tank is equipped with a propeller water pump 7, a settling tank flow rate adjustment hole 6, and an oily substance comb hole 20.

[0098] Submersible pump 23: Pumps the water treated by the biochemical adsorption tank 25 and biochemical tank 24 into the fish tank. Power is between 30 watts and 40 watts.

[0099] Biochemical tank 24: Place ceramic rods, ceramic balls and other biochemical materials into the tank to produce nitrifying bacteria to treat organic matter in the water.

[0100] Biochemical adsorption tank 25: Biochemical cotton is placed in the tank to produce nitrifying bacteria that adsorb tiny impurities and suspended solids in the water, thus treating the organic matter in the water.

[0101] Work process:

[0102] The propeller pump 7 discharges water from the fish waste settling collector, and in conjunction with the submersible pump outlet pipe 8, pushes the water and fish waste in the aquarium towards the main inlet 2 of the collector and the waste inlet 1 of the settling tank. Since the fish waste flows at the bottom of the aquarium, it enters the waste inlet 1 of the settling tank. The water flowing above the fish waste enters the main inlet 2 of the collector. The water entering the main inlet 2 does not enter the settling tank but flows out above it. This completes the first separation: the fish waste and a small amount of water are separated from the majority of the flowing water. After the fish waste and a small amount of water enter the settling tank, because the cross-sectional area of ​​the waste inlet 1 is several times smaller than the cross-sectional area of ​​the settling tank, the water flow velocity in the settling tank is also several times lower than the flow velocity at the waste inlet 1. Under this dual effect, the upward flow velocity of the water in the settling tank is lower than the downward sinking velocity of the fish waste. The fish waste sinks to the fish waste storage area, thus completing the second separation.

[0103] Organic matter and small suspended debris in the aquarium water enter the overflow pipe 11. After being oxygenated by the flow and collision, it flows into the biochemical adsorption tank 25 and the biochemical tank 24. In the biochemical adsorption tank 25, the suspended debris is adsorbed by nitrifying bacteria in the biochemical cotton. In the biochemical tank 24, the organic matter is processed by nitrifying bacteria.

[0104] During fish waste collection, the waste is not blocked by objects or subjected to rapid collisions, maintaining its original shape, remaining intact, and not polluting the water. This effectively blocks the main source of pollution. The content of nitrifying bacteria in the biomaterials and water will gradually increase until saturation.

[0105] Working principle:

[0106] 1. This patent employs a two-stage separation process between fish waste and flowing water. The first separation utilizes the principle that fish waste flows along with the water at the bottom of the fish tank. The waste inlet 1 of the sedimentation tank is installed at the bottom of the fish tank to collect the fish waste flowing from the bottom. The main water inlet 2 of the collector is installed above the waste inlet 1 of the sedimentation tank, away from the bottom of the fish tank to prevent fish waste from flowing in. The water entering the fish waste sedimentation collector mainly enters through the main water inlet 2 of the collector, and the waste inlet 1 of the sedimentation tank.

[0107] The process involves a second settling separation of fish waste and flowing water: a lower settling tank 15 and an upper settling tank 16 are used to separate the fish waste. The upward flow velocity of the water within the settling tanks is reduced, ensuring that the upward flow velocity is lower than the settling velocity of the fish waste. The water flow velocity within the settling tanks is divided into three zones: a straight flow zone, a settling zone, and a fish waste storage zone where the water flow is almost stagnant.

[0108] 2. The cross-sectional areas of the main inlet 2 of the collector and the inlet 1 of the settling tank must be properly set to ensure that fish waste quickly passes over the fish waste storage platform 3 in the settling tank, and that the upward flow velocity of the water in the lower settling tank 15 is not higher than the settling velocity of the fish waste. The position of the main inlet 2 of the collector must be properly set so that the fish waste flows quickly to the front of the inlet 1 of the settling tank, but does not enter the main inlet 2 of the collector. Specifically:

[0109] A larger cross-sectional area of ​​the collector's main inlet 2 results in a slower water flow rate in the settling tank, while a smaller cross-sectional area results in a faster water flow rate. In this embodiment, the cross-sectional area of ​​the collector's main inlet 2 is 4 to 12 times that of the settling tank inlet 1.

[0110] The main inlet 2 of the collector should not be too high or too low from the bottom of the fish tank. In this embodiment, the main inlet 2 of the collector is 2cm to 12cm from the bottom of the fish tank. If the main inlet 2 of the collector is too high from the bottom of the fish tank, the fish waste will stay in front of the waste inlet 1 of the sedimentation tank for a longer time. If the main inlet 2 of the collector is too close to the bottom of the fish tank, the fish waste will be sucked in by the main inlet.

[0111] The water flowing into the main inlet 2 of the collector must not enter the settling tank; the water flowing into the main inlet 2 of the collector must flow out above the upper settling tank 16.

[0112] The cross-sectional area of ​​the main inlet 2 of the collector should not be too large or too small. If the cross-sectional area of ​​the main inlet 2 is too large, the water flow rate will be high, resulting in a low water flow rate and slow flow velocity in the settling tank. Fish waste will have difficulty crossing the fish waste storage platform 3 in the settling tank and will easily accumulate at the waste inlet 1 of the settling tank. If the cross-sectional area of ​​the main inlet 2 is too small, the water flow rate will be low, resulting in a high water flow rate and fast flow velocity in the settling tank, making it difficult for the fish waste to settle downwards.

[0113] The cross-sectional area of ​​the inlet 1 of the settling tank cannot be too large or too small. If it is too large, the water flow rate inside the settling tank will be faster, making it difficult for fish waste to sink. If it is too small, fish waste will have difficulty entering the settling tank. In this embodiment, the cross-sectional area of ​​the settling tank is 15 to 40 times the cross-sectional area of ​​the inlet 1.

[0114] 3. Assistive platform 4 above the inlet and fish waste storage platform 3 in the settling tank:

[0115] A fish waste storage platform 3 is located at the inlet 1 of the settling tank. Behind the fish waste storage platform 3, a fish waste storage area with almost no water flow is formed, and the height of the fish waste storage platform 3 is higher than the upper edge of the inlet 1. This is mainly to allow the fish waste and water to flow diagonally upwards. An assist platform 4 on the inlet allows the fish waste to quickly cross the fish waste storage platform 3 without slowing down. The fish waste settles behind the fish waste storage platform 3 and enters the fish waste storage area.

[0116] 4. Partition hole cover plate 12 and sinking trough agitator plate 13:

[0117] The partition hole cover 12 and the sinking trough agitator 13 are integrated. The partition hole cover 12 covers the cleaning and installation partition opening 18, forming the upper sinking trough 16 for storing fish waste. The sinking trough agitator 13 is installed outside the overflow pipe 11 and connected to the cover agitator rod 14, allowing it to swing up and down and be easily removed. When the forced discharge hole 19 is opened, the cover agitator rod 14 is pulled to swing up and down, agitating and discharging the fish waste settled in the fish waste storage area.

[0118] The technical solution described in this embodiment has at least the following technical effects or advantages:

[0119] This configuration divides the water flow within the settling tank 15 into three zones: a linear flow zone between the settling tank inlet 1 and the settling tank outlet 17, a settling zone, and a fish waste storage zone. The settling zone comprises the main parts of the lower settling tank 15 and the upper settling tank 16. The upper settling tank 16 extends from the collector's main inlet outlet to the baffle cover 12, and its function is to settle the waste exiting from the collector's main inlet outlet 5. The upward flow speed of the water within the lower settling tank 15 is lower than the settling speed of the fish waste.

[0120] The main parts of the lower settling tank 15 and the upper settling tank 16 are the settling areas. The upper settling tank 16 is the space between the main inlet outlet of the collector and the baffle hole cover plate 12. The main function of the upper settling tank 16 is to settle the feces coming out of the main inlet outlet of the collector.

[0121] The baffle hole cover plate 12 and the sinking trough agitator plate 13 are connected and fixed by the cover plate agitator plate connecting rod 14. The three are integrated and fit over the overflow pipe. They can slide up and down and can also be easily removed. When defecating, the cover plate agitator plate connecting rod 14 slides up and down to agitate the fish waste that has settled in the fish waste storage area and discharge it together with the water.

[0122] Example 5

[0123] Based on Embodiment 1, the settling tank is divided into an upper settling tank 16 and a lower settling tank 15 by a settling tank water flow brush 27. A settling tank agitator 28 is provided below the settling tank water flow brush 27. The settling tank water flow brush 27 and the settling tank agitator 28 are connected by an agitator rod 29. The agitator rod 29 is sleeved on the overflow pipe 11 and can move up and down along the overflow pipe 11.

[0124] Specifically, as shown in the instruction manual Figures 4-7 As shown, this embodiment includes:

[0125] Water flow control brush 27 in settling tank: The function of water flow control brush 27 in settling tank is to control the uniform flow of water in settling tank and prevent the water in the tank from generating eddies and flowing up and down.

[0126] Settling tank agitator 28: The settling tank agitator 28 is connected to the agitator rod 29. It swings up and down during defecation to agitate and remove the fish waste that has settled in the fish waste storage area.

[0127] Stirring plate rod 29: The stirring plate rod 29, the settling tank water flow control brush 27, and the settling tank stirring plate 28 are integrated. The stirring plate rod 29 is installed outside the overflow pipe 11, can slide up and down, and can also be easily removed.

[0128] Work process:

[0129] During normal operation, the water flow control brush 27 in the settling tank is positioned approximately 10cm from the bottom of the fish waste settling collector, allowing fish waste and a small amount of flowing water to enter the settling tank through the waste inlet 1. Fish waste exiting the waste inlet 1 settles downwards and enters the fish waste storage area. Water exiting the waste inlet 1 flows upwards through the gap between the water flow control brush 27 and the side wall of the settling tank, exiting the settling tank and entering the upper part of the fish waste settling collector.

[0130] The technical solution described in this embodiment has at least the following technical effects or advantages:

[0131] The function of the water flow control brush 27 in the settling tank is to control the uniform flow of water within the settling tank, preventing eddies and vertical movement. The water flow control brush 27 solves the problem of water rising upwards and also adsorbs some small suspended particles. Furthermore, the distance between the end of the water flow control brush 27 and the side wall of the fish waste settling collector is 0.45-0.55 cm to prevent the brush from being clogged by nitrifying bacteria, thus preventing water from flowing upwards.

[0132] Example 6

[0133] Based on Embodiment 1, the sidewall of the sedimentation tank is provided with a water flow control brush 30, which is divided into two groups and respectively set on two adjacent sidewalls of the fish waste sedimentation collector.

[0134] Specifically, as shown in the instruction manual Figures 8-9 As shown, this embodiment includes: water flow control brushes 30: two sets of water flow control brushes 30 are respectively installed on two adjacent side walls of the fish waste sedimentation collector.

[0135] Work process:

[0136] Fish waste and flowing water enter the settling tank through the inlet 1, where the space expands and the flow rate slows down. The fish waste settles downwards into the fish waste storage area. The flowing water flows upwards, passing through the gap between the control flow brush 30 and the side wall of the settling tank, and through the outlet not covered by the control flow brush 30, flowing out of the settling tank and into the upper part of the fish waste settling collector. The control flow brush 30 can adsorb suspended solids in the water entering the settling tank, preventing the water in the settling tank from surging up and down. It also facilitates the use of a long pole to clean the brushes, allowing for cleaning of all corners of the settling tank.

[0137] The water flow control brush 30 not only adsorbs suspended solids in the water but also acts as a baffle between the lower settling tank 15 and the upper settling tank 16, preventing water from surging up and down within the settling tank. Large outlet gaps at the corners prevent small gaps from becoming clogged with suspended solids, facilitating water flow out of the lower settling tank 15. Using the water flow control brush 30 as a baffle allows the long-arm cleaning brush to easily access and clean every corner of the lower settling tank 15.

[0138] The technical solution described in this embodiment has at least the following technical effects or advantages:

[0139] The water flow control brush 30 solves the problem of water gushing upwards while avoiding the problem of uneven brush distribution.

[0140] Example 7

[0141] In this embodiment, the third embodiment is improved by changing the sedimentation tank fish waste storage platform 3 (narrower at the top and wider at the bottom) and the inlet assist platform 4 (wider at the bottom) to two parallel plates.

[0142] The technical solution described in this embodiment has at least the following technical effects or advantages:

[0143] Using two parallel plates as the fish waste storage platform 3 and the auxiliary platform 4 at the waste inlet of the sedimentation tank makes it easier to manufacture the mold. The rear of the waste inlet 1 of the sedimentation tank is a rectangular channel with an equal cross-sectional area that slopes upwards, and the outlet of the channel is higher than the upper edge of the waste inlet 1 of the sedimentation tank.

[0144] Example 8

[0145] The inlet 1 of the sedimentation tank and the main inlet 2 of the collector are located on the two side plates of the fish waste sedimentation collector.

[0146] The side wall 22 of the fish waste settling collector is provided with at least two settling tank flow rate adjustment holes 6; the flow rate of water in the settling tank can be adjusted by increasing or decreasing the number of settling tank flow rate adjustment holes 6.

[0147] A propeller pump 7 is installed on the side wall 22 of the fish waste sedimentation collector. The propeller pump 7 is located below the water level line of the aquarium, which drains the water in the sedimentation tank and promotes the circulation of water in the aquarium.

[0148] The side wall 22 of the fish waste sediment collector has oil-draining comb holes 20, and the water level line of the aquarium is located between the upper and lower edges of the oil-draining comb holes 20. The diameter of the oil-draining comb holes 20 is between 0.1 cm and 0.2 cm. This drains the oily substance floating on the surface of the aquarium and blocks fish food.

[0149] The technical solution described in this embodiment has at least the following technical effects or advantages:

[0150] A propeller pump 7 is installed on the side of the fish waste settling collector. It discharges water from the collector, circulates the water in the aquarium, and pushes the fish waste towards the inlet 1 of the settling tank, sucking it in. Most of the flowing water is drawn into the main inlet 2 of the collector and flows back into the fish waste settling collector, forming a water cycle. In this embodiment, a very low-power propeller pump 7 replaces part of the submersible pump, significantly reducing the power, noise, and electricity consumption of the submersible pump.

[0151] Example 9

[0152] The overflow pipe outlet 10 of the aquarium's overflow pipe 11 is connected to the biochemical adsorption tank 25, which is connected to the biochemical tank 24. The submersible pump 23 delivers the water from the biochemical tank 24 to the end of the submersible pump outlet pipe 8. The end of the submersible pump outlet pipe 8 and the fish waste sedimentation collector are located at both ends of the aquarium. The overflow pipe inlet 9 of the overflow pipe 11 is located inside the fish waste sedimentation collector.

[0153] In the biological treatment tank 24, ceramic rods, ceramic balls, and other biological materials are placed to produce nitrifying bacteria that treat organic matter in the water. In the biological adsorption tank 25, biological cotton is placed to produce nitrifying bacteria that adsorb tiny impurities and suspended solids in the water, thus treating the organic matter in the water.

[0154] In summary, the present invention provides a fish waste sedimentation collector and a sedimentation adsorption aquarium.

[0155] The above embodiments have provided a detailed description of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
