Description

Technical Field

[0001] The utility model belongs to the technical field of aquariums, and particularly relates to a fish feces sedimentation collector and a non-filtering ecological fish tank. Background Art

[0002] Existing technology:

[0003] As people's living standards improve, more and more people like to raise fish and grow flowers. Aquariums are the most popular way to raise ornamental fish. The aquarium has a small space and many fish, and the fish feces are broken, which pollutes the water quality and becomes the biggest problem. In addition, due to the large flow of circulating water in the aquarium and the large amount of fish feces, high-density filter materials cannot be used for filtration.

[0004] The existing technology for solving the problem of collecting fish feces in aquariums mainly involves collecting fish feces by filtering, or using a filter box or a dry-wet separation box.

[0005] The following problems exist when collecting fish feces by filtering: If the internal gaps of the filter material are large, tiny debris can easily pass through the filter material. If the internal gaps of the filter material are small, water will continuously wash the fish feces blocked by the filter material, and the fish feces will be easily broken, releasing organic matter, viruses of sick fish, and tiny debris suspended matter into the water. The result is that the fish feces are broken and pollute the water quality. What is cleaned is the fish feces and residue, and what is polluted is the water.

[0006] The use of filter boxes or dry-wet separation boxes has the following problems: the water flow rate in the box is too fast, and it is difficult for the nitrifying bacteria in the gaps in the filter material to adsorb tiny suspended debris.

[0007] At the same time, when filtering and collecting fish feces, or using filter boxes or dry-wet separation boxes, a submersible pump is required. If a submersible pump is used to pump water into the upper fish tank to promote water circulation and collect fish feces, there are the following problems: on the one hand, the water flow rate is fast, the feces are easily broken, and the water quality is polluted; on the other hand, the submersible pump has the disadvantages of high head, large flow, high power, large up and down circulation, high noise, and high power consumption.

[0008] In short, the biggest drawback of an aquarium is that the fish excrement is broken and pollutes the water quality. There are two main reasons for the fish excrement to be broken. 1. The fish excrement flows from the upper box to the lower box in a rapid flow and collision, and the fish excrement is broken and pollutes the water quality. 2. The filter collects the fish excrement. When the filter blocks the fish excrement, the water keeps flushing, and the fish excrement is broken and pollutes the water quality.

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

[0010] Therefore, based on these problems, providing a fish feces sedimentation collector and a non-filter ecological fish tank has important practical significance. Utility Model Content

[0027] One or more technical solutions provided in the embodiments of the present application have at least the following beneficial effects:

[0028] 1. The utility model does not use filtration to collect fish feces, and does not allow fish feces to enter the overflow pipe and flow to the lower box. The main problem of fish feces being broken and polluting the water quality is solved. The utility model uses a sedimentation tank to collect feces, and the bottom of the fish feces sedimentation collector is provided with a sedimentation tank inlet and a collector main water inlet. Most of the circulating water in the fish tank enters the collector main water inlet, which only serves to push the fish feces to gather at the sedimentation tank inlet and does not enter the sedimentation tank. Only a small amount of flowing water and fish feces enter the sedimentation tank through the sedimentation tank inlet. In this way, the fish feces can be quickly sucked to the front of the inlet, but the fish feces cannot be sucked into the main water inlet. Using a sedimentation tank to collect fish feces can maintain the original shape of the fish feces, prevent them from being broken, and do not pollute the water quality.

[0029] 2. The utility model adopts secondary separation of fish feces and flowing water. The first separation of fish feces and flowing water uses the principle that fish feces flow with water at the bottom of the fish tank, so that the fish feces are separated from most of the flowing water before entering the sedimentation tank, and a small amount of flowing water and fish feces enter the sedimentation tank. The second sedimentation separation of fish feces and flowing water uses the upward flow rate of water in the sedimentation tank to be lower than the sedimentation speed of fish feces to make the fish feces settle.

[0030] 3. A fish excrement storage area with almost no water flow is formed behind the sedimentation tank fish excrement storage platform of the utility model. Since a fish excrement passage with an equal distance is formed between the upper assisting platform of the inlet and the sedimentation tank fish excrement storage platform, the fish excrement entering the sedimentation tank inlet will quickly pass over the sedimentation tank fish excrement storage platform and enter the sedimentation area, and settle to the fish excrement storage area. At the same time, the height of the sedimentation tank fish excrement storage platform is higher than the upper edge of the sedimentation tank inlet, which facilitates the water to flow obliquely upward.

[0031] 4. The height of the main water inlet of the collector of the utility model from the bottom of the fish tank is more than 2 cm and less than 12 cm. If the main water inlet of the collector is higher than the bottom of the fish tank, the fish feces will stay in front of the feces inlet of the sedimentation tank for a long time. If the main water inlet of the collector is close to the bottom of the fish tank, the fish feces will be sucked into the main water inlet.

[0032] 5. The outlet pipe end of the submersible pump and the propeller water pump of the utility model are located at both ends of the aquarium, and the two cooperate with each other to promote the circulation of water in the fish tank, which can reduce the power of the submersible pump. Only a very small power propeller water pump needs to be installed above the fish tank.

[0033] 6. The cross-sectional area of ​​the sedimentation tank of the utility model is 15 to 40 times the cross-sectional area of ​​the sedimentation tank inlet, so that the upward flow velocity of the water in the sedimentation tank decreases. The sedimentation tank is divided into three areas according to the flow velocity of the water, namely, the linear flow area between the sedimentation tank inlet and the water outlet of the lower sedimentation tank, the fish feces storage area behind the sedimentation tank fish feces storage platform where the water hardly flows, and the sedimentation area (the area after the sedimentation tank removes the linear flow area and the fish feces storage area).

[0034] 7. The main parts of the lower settling tank and the upper settling tank of the utility model are the settling areas. Among them, the upper settling tank is the space between the main water inlet and outlet of the collector and the cover plate of the partition hole. The function of the upper settling tank is mainly to settle the feces coming out of the main water inlet and outlet of the collector.

[0035] 8. The partition hole cover plate and the lower sedimentation tank defecation stirring plate of the utility model are connected and fixed by the cover plate stirring plate connecting rod. The three are integrated and are integrally sleeved outside the overflow pipe. They can slide up and down and can be easily taken down. When defecation, the cover plate stirring plate connecting rod is slid up and down to stir the fish feces settled in the fish feces storage area and discharge it together with the water.

[0036] 9. The utility model adopts a brush to control the water flow of the sedimentation tank to solve the problem of water surging upwards, and at the same time can absorb some tiny suspended matter. The distance between the end of the brush to control the water flow of the sedimentation tank and the side wall of the fish feces sedimentation collector is 0.45-0.55cm, which prevents the brush from being stuck by nitrifying bacteria and preventing water from flowing upwards.

[0037] 10. The utility model adopts a water flow control brush to solve the problem of water surging upward and avoid the problem of uneven brush distribution. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] Example 1

[0055] The fish feces sedimentation collector of this embodiment is installed on an aquarium, and the fish feces sedimentation collector includes a sedimentation tank. The fish feces sedimentation collector is provided with a sedimentation tank inlet 1 and a collector main water inlet 2 at the bottom of the sedimentation tank. The lower edge of the sedimentation tank inlet 1 is flush with the bottom of the aquarium, and the collector main water inlet 2 is located above the sedimentation tank inlet 1. Water entering the collector main water inlet 2 flows upward along the side wall 22 and the guide plate 21 of the fish feces sedimentation collector.

[0056] The technical solution in the above embodiment has at least the following technical effects or advantages:

[0057] This embodiment uses a sedimentation tank to collect feces, and the bottom of the fish feces sedimentation collector is provided with a sedimentation tank inlet and a collector main water inlet. Most of the circulating water in the fish tank enters the collector main water inlet, which only serves to push the fish feces to gather at the sedimentation tank inlet and does not enter the sedimentation tank. Only a small amount of flowing water and fish feces enter the sedimentation tank through the sedimentation tank inlet. In this way, the fish feces can be quickly sucked to the inlet, but the fish feces cannot be sucked into the main water inlet. The use of a sedimentation tank to collect fish feces can maintain the original shape of the fish feces, without breaking it and polluting the water quality.

[0058] This embodiment adopts sedimentation to collect fish feces, and the biggest advantage is that the fish feces are not broken and do not pollute the water. Since the fish feces need to flow at the bottom of the fish tank, the overall circulation flow rate needs to be very large, and a large flow of water is required to push the fish feces to flow to the feces inlet, and the large flow of water cannot enter the sedimentation tank. In this embodiment, a sedimentation tank feces inlet 1 and a collector main water inlet 2 are opened at the bottom of the fish feces sedimentation collector. Since the flow rates of the sedimentation tank feces inlet 1 and the collector main water inlet 2 are equal, the fish feces flow at the bottom of the fish tank, so the fish feces will enter the sedimentation tank feces inlet 1 together with a small amount of flowing water and flow into the sedimentation tank. The collector main water inlet 2 not only uses a large flow of water to push the fish feces in the fish tank to gather in front of the sedimentation tank feces inlet 1, but also only inhales the water flowing above the fish feces. The water entering the collector main water inlet 2 flows into the fish feces sedimentation collector above the sedimentation tank. The fish feces are separated from most of the flowing water, creating conditions for the next step of sedimentation and collection of fish feces.

[0059] This embodiment adopts sedimentation adsorption to collect fish feces and sundry suspended solids dissolved in water, and the fish feces do not enter the overflow pipe and flow into the lower box. Because the circulating water flows at a certain speed in the fish tank of the upper box of the aquarium, the fish feces will move to the feces inlet 1 of the sedimentation tank, and such a large amount of flowing water cannot enter the sedimentation tank. This embodiment uses the principle that the fish feces flow at the bottom of the fish tank. After the majority of the circulating water brings the fish feces to the feces inlet 1 of the sedimentation tank, it is separated from the fish feces and enters the main water inlet 2 of the collector, and enters the fish feces sedimentation collector above the sedimentation tank. A small amount of flowing water and fish feces enter the sedimentation tank, the space becomes larger, and the water flow rate is lower than the speed of fish feces sedimentation, and the fish feces settle to the fish feces storage area behind the storage table.

[0060] Example 2

[0061] Based on Example 1, the end of the collector main water inlet is the collector main water inlet outlet 5. In order to prevent water from the collector main water inlet 2 from entering the sedimentation tank, the collector main water inlet outlet 5 is located above the sedimentation tank; the height of the collector main water inlet from the bottom of the fish tank is above 2 cm and below 12 cm.

[0062] The collector main water inlet 2, the collector main water inlet outlet 5 and the sedimentation tank inlet 1 are all rectangular holes.

[0063] The technical solution in the above embodiment has at least the following technical effects or advantages:

[0064] Since the main water inlet and outlet 5 of the collector are located above the sedimentation tank, the water entering the main water inlet 2 of the collector flows upward along the side wall 22 and the guide plate 21 of the fish feces sedimentation collector and enters the upper part of the fish feces sedimentation collector, which creates conditions for sedimentation and collection of fish feces through the sedimentation tank, and can separate most of the flowing water from the fish feces.

[0065] Example 3

[0066] On the basis of Example 1, the lower edge of the sedimentation trough inlet 1 is a sedimentation trough fish feces storage platform 3. The sedimentation trough fish feces storage platform 3 is a narrow upper and wide lower structure with a height between 1 cm and 1.5 cm. The lower edge of the sedimentation trough fish feces storage platform 3 is flush with the bottom of the aquarium, and a fish feces storage area with almost no water flowing is formed behind the sedimentation trough fish feces storage platform 3.

[0067] Above the stool inlet 1 of the sedimentation tank is an upper stool inlet assisting platform 4, which is arranged opposite to the sedimentation tank fish feces storage platform 3, and a channel with equal cross-section along the water flow direction is formed between the two. This is conducive to the fish feces quickly passing over the sedimentation tank fish feces storage platform 3 and settling to the fish feces storage area.

[0068] The technical solution in the above embodiment has at least the following technical effects or advantages:

[0069] A fish excrement storage area with almost no water flow is formed behind the sedimentation tank fish excrement storage platform 3. Since a fish excrement passage with an equal distance is formed between the upper assisting platform 4 of the inlet and the sedimentation tank fish excrement storage platform 3, the fish excrement entering the sedimentation tank inlet 1 will quickly pass over the sedimentation tank fish excrement storage platform 3 and enter the sedimentation area, and settle in the fish excrement storage area. At the same time, the height of the sedimentation tank fish excrement storage platform 3 is higher than the upper edge of the sedimentation tank inlet 1, which facilitates the water to flow obliquely upward.

[0070] Since the storage platform 3 at the inlet of the sedimentation tank has a certain height, a fish feces storage area with almost no water flowing is formed behind it. Since a fish feces passage with an equal distance is formed between the upper auxiliary platform 4 at the inlet and the storage platform 3 of the sedimentation tank, and the water flow rate at the inlet of the sedimentation tank 1 is fast, when the fish feces approach the inlet of the sedimentation tank 1, they will be sucked into the fish feces passage and quickly pass through the sedimentation storage platform 3, and the fish feces will settle to the fish feces storage area behind the fish feces storage platform 3 of the sedimentation tank, and then be discharged when defecation is needed.

[0071] Example 4

[0072] On the basis of Example 1, the sedimentation tank is divided into an upper sedimentation tank 16 and a lower sedimentation tank 15 by a partition hole cover 12. The upper sedimentation tank 16 and the lower sedimentation tank 15 are connected through a cleaning and installation partition opening 18 and a lower sedimentation tank outlet hole 17. The partition hole cover 12 covers the cleaning and installation partition opening 18. The cross-sectional area of ​​the sedimentation tank is 15 to 40 times the cross-sectional area of ​​the sedimentation tank inlet.

[0073] A lower sedimentation trough defecation stirring plate 13 is provided below the partition hole cover plate 12. The partition hole cover plate 12 and the lower sedimentation trough defecation stirring plate 13 are connected and fixed by a cover plate stirring plate connecting rod 14. The cover plate stirring plate connecting rod 14 is sleeved on the overflow pipe 11 and the cover plate stirring plate connecting rod 14 can move up and down along the overflow pipe 11. A forced defecation hole 19 is opened at the bottom of the lower sedimentation trough 15.

[0074] Specifically, as shown in the attached manual Figure 1-3 As shown, this embodiment includes:

[0076] Main water inlet 2 of the collector: The water entering the fish feces sedimentation collector mainly enters through the main water inlet 2 of the collector. The main water inlet 2 of the collector is located above the feces inlet 1 of the sedimentation tank, 2cm to 12cm away from the bottom of the fish tank. In this way, the fish feces can be quickly sucked to the front of the feces inlet 1 of the sedimentation tank, while preventing the fish feces from entering the main water inlet 2 of the collector.

[0077] Sedimentation trough fish feces storage platform 3: A sedimentation trough fish feces storage platform 3 is provided at the sedimentation trough inlet 1, and its height is between 1 cm and 1.5 cm. A fish feces storage area with almost no water flowing is formed behind the sedimentation trough fish feces storage platform 3.

[0078] The assisting platform 4 on the feces inlet is arranged opposite to the fish feces storage platform 3 in the sedimentation tank, and a fish feces and water channel with equal distance is formed between the two, which is conducive to the fish feces quickly passing through the fish feces storage platform 3 in the sedimentation tank and settling to the fish feces storage area.

[0079] Collector main water inlet and outlet 5: In order to prevent water from the collector main water inlet 2 from entering the sedimentation tank, the collector main water inlet and outlet 5 should be above the sedimentation tank.

It discharges the water in the sedimentation tank, promotes the water circulation in the fish tank, drives the fish feces to flow into the sedimentation tank feces inlet 1, and most of the water flows into the collector main water inlet 2.

[0082] Submersible pump outlet pipe 8: connected to the submersible pump 23, through the sedimentation tank and the overflow pipe 11, to pump the water from the biochemical tank 24 into the fish tank.

[0084] Overflow pipe water outlet 10: The water in the overflow pipe 11 flows out, and the pipe wall collides with the water to increase oxygen.

[0085] Overflow pipe 11: The water in the overflow pipe 11 collides with the pipe wall to increase oxygen.

[0086] Partition hole cover plate 12: covers the cleaning installation partition opening 18, opens during defecation and cleaning.

[0088] Cover plate stirring plate connecting rod 14: When defecation, pull the cover plate stirring plate connecting rod 14 to swing up and down, so that the fish feces settled in the lower sedimentation tank 15 and the upper sedimentation tank 16 are suspended and discharged.

[0089] Lower settling tank 15: The water flow in the lower settling tank 15 is divided into three areas, the linear flow area between the settling tank inlet 1 and the lower settling tank outlet 17, the settling area (including the main part of the lower settling tank 15 and the upper settling tank 16, wherein the range of the upper settling tank 16 is between the main water inlet and outlet of the collector and the partition hole cover 12, and the function of the upper settling tank 16 is to settle the feces coming out of the main water inlet and outlet of the collector), and the fish feces storage area. The speed of water flowing upward in the lower settling tank 15 is lower than the speed of fish feces settling.

[0090] Upper sedimentation tank 16: collects, settles and stores fish excrement. The upward flow speed of water in the upper sedimentation tank 16 is lower than the sedimentation speed of fish excrement.

[0091] The water outlet hole 17 of the lower settling tank is used to discharge the excess water in the lower settling tank 15 .

[0092] Cleaning and installing the partition opening 18: it is convenient to install the overflow pipe 11, the forced discharge hole 19 and the cleaning lower sedimentation tank 15.

[0096] Fish feces sedimentation collector side wall 22: The fish feces sedimentation collector side wall 22 close to the fish tank is equipped with a propeller water pump 7, a sedimentation tank flow rate adjustment hole 6 and an oil discharge comb hole 20.

[0097] Submersible pump 23: pumps the water treated by biochemical adsorption tank 25 and biochemical tank 24 into the fish tank. The power is between 30 watts and 40 watts.

[0098] Biochemical tank 24: Ceramic rods, ceramic balls and other biochemical materials are placed to produce nitrifying bacteria to treat organic matter in the water.

[0099] Biochemical adsorption tank 25: Biochemical cotton is placed in the tank to produce nitrifying bacteria to adsorb tiny suspended matter in the water and treat organic matter in the water.

[0100] Working process:

[0101] The propeller water pump 7 discharges the water in the fish feces sedimentation collector, and cooperates with the submersible pump outlet pipe 8 to push the water and fish feces in the fish tank to flow toward the collector main water inlet 2 and the sedimentation tank feces inlet 1. Since the fish feces flow at the bottom of the fish tank, the fish feces will enter the sedimentation tank feces inlet 1, and the flowing water above the fish feces enters the collector main water inlet 2. The water entering the collector main water inlet 2 does not enter the sedimentation tank, but flows out above the sedimentation tank. Thus, the first separation is completed, that is, the fish feces and a small amount of water are separated from most of the flowing water. After the fish feces and a small amount of water enter the sedimentation tank, since the cross-sectional area of ​​the sedimentation tank feces inlet 1 is several times smaller than the cross-sectional area of ​​the sedimentation tank, the flow rate of the water in the sedimentation tank is also several times lower than the flow rate of the sedimentation tank feces inlet 1. Under the dual effect, the upward flow rate of the water in the sedimentation tank is lower than the speed at which the fish feces settle downward. The fish feces settle downward to the fish feces storage area, thereby completing the second separation.

[0102] The organic matter and tiny suspended debris in the water of the fish tank enter the overflow pipe 11, and after being oxygenated in the flow collision, flow into the biochemical adsorption tank 25 and the biochemical tank 24. In the biochemical adsorption tank 25, the suspended debris is adsorbed by the nitrifying bacteria in the biochemical cotton. In the biochemical tank 24, the organic matter is treated by the nitrifying bacteria.

[0103] In the process of collecting fish feces, the fish feces will not be blocked or collided quickly by objects, and the original shape of the fish feces will be maintained, and the fish feces will not be broken or pollute the water quality. The main pollution source is blocked. The content of biochemical materials and nitrifying bacteria in the water will increase until saturation.

[0104] Working principle:

[0105] 1. This patent adopts the secondary separation of fish feces and flowing water, wherein the first separation of fish feces uses the principle that fish feces flow with water at the bottom of the fish tank. The sedimentation tank feces inlet 1 is installed at the bottom of the fish tank to collect fish feces flowing from the bottom of the fish tank. The collector main water inlet 2 is installed above the sedimentation tank feces inlet 1, away from the bottom of the fish tank to prevent fish feces from flowing in. The water entering the fish feces sedimentation collector mainly enters from the collector main water inlet 2 and the sedimentation tank feces inlet 1.

[0106] Among them, the fish excrement and flowing water are separated by sedimentation for the second time: the fish excrement is separated by the lower sedimentation tank 15 and the upper sedimentation tank 16. The upward flow rate of the water in the sedimentation tank is reduced, and the fish excrement is collected by sedimentation by ensuring that the speed of the water flowing upward is lower than the speed of the fish excrement sedimentation. The flow rate of the water in the sedimentation tank is divided into three areas, a linear flow area, a sedimentation area, and a fish excrement storage area where the water hardly flows.

[0107] 2. The cross-sectional area of ​​the collector main water inlet 2 and the sedimentation tank feces inlet 1 should be set properly to ensure that the fish feces quickly pass through the sedimentation tank fish feces storage table 3, and the upward flow rate of the water in the lower sedimentation tank 15 cannot be higher than the sedimentation speed of the fish feces. The position of the collector main water inlet 2 should be set properly to allow the fish feces to quickly flow to the front of the sedimentation tank feces inlet 1, but not allow the fish feces to enter the collector main water inlet 2. Specifically:

[0108] The cross-sectional area of ​​the collector main water inlet 2 is large, and the flow rate of water in the sedimentation tank is just slow, and its cross-sectional area is small, and the flow rate of water in the sedimentation tank is just fast. In the present embodiment, the cross-sectional area of ​​the collector main water inlet 2 is 4~12 times the cross-sectional area of ​​the sedimentation tank inlet 1.

[0109] The main water inlet 2 of the collector cannot be too high or too low from the bottom of the fish tank. In this embodiment, the main water inlet 2 of the collector is 2 cm to 12 cm away from the bottom of the fish tank. If the main water inlet 2 of the collector is high from the bottom of the fish tank, the fish feces will stay in front of the feces inlet 1 of the sedimentation tank for a long time. If the main water inlet 2 of the collector is close to the bottom of the fish tank, the fish feces will be sucked into the main water inlet.

[0110] The water flow entering the main water inlet 2 of the collector cannot enter the sedimentation tank, and the water flow entering the main water inlet 2 of the collector must flow out above the upper sedimentation tank 16.

[0111] The cross-sectional area of ​​the main water inlet 2 of the collector cannot be too large or too small. If the cross-sectional area of ​​the main water inlet 2 of the collector is large, the water flow rate is large, resulting in a small water flow rate and slow flow rate in the sedimentation tank. It is difficult for fish feces to pass through the sedimentation tank fish feces storage table 3 and it is easy to accumulate at the sedimentation tank feces inlet 1. If the cross-sectional area of ​​the main water inlet 2 of the collector is small, the water flow rate is small, resulting in a large water flow rate and fast flow rate in the sedimentation tank, and it is difficult for fish feces to settle down.

[0112] The cross-sectional area of ​​the feces inlet 1 of the sedimentation tank cannot be too large or too small. If it is too large, the water flow rate inside the sedimentation tank will be faster, and it will be difficult for fish to sink downward. If it is too small, it will be difficult for fish to enter the sedimentation tank. In this embodiment, the cross-sectional area of ​​the sedimentation tank is 15 to 40 times the cross-sectional area of ​​the feces inlet 1 of the sedimentation tank.

[0113] 3. The upper assisting platform 4 at the feces inlet and the fish feces storage platform 3 at the sedimentation tank:

[0114] There is a sedimentation tank fish feces storage platform 3 at the sedimentation tank inlet 1. A fish feces storage area with almost no water flowing is formed behind the sedimentation tank fish feces storage platform 3, and the height of the sedimentation tank fish feces storage platform 3 is higher than the upper edge of the sedimentation tank inlet 1. The main purpose is to allow fish feces and water to flow obliquely upward. The booster platform 4 on the inlet can allow fish feces to quickly pass over the sedimentation tank fish feces storage platform 3 without slowing down. The fish feces settle behind the sedimentation tank fish feces storage platform 3 and enter the fish feces storage area.

[0115] 4. Partition hole cover plate 12 and lower sedimentation tank defecation stirring plate 13:

[0116] The partition hole cover plate 12 and the lower sedimentation tank excrement stirring plate 13 are integrated. The partition hole cover plate 12 covers the cleaning and installation partition opening 18 to form an upper sedimentation tank 16 for storing fish feces. The lower sedimentation tank excrement stirring plate 13 is installed outside the overflow pipe 11 and is connected to the cover plate stirring plate connecting rod 14. It can swing up and down and can be easily taken down. When the forced discharge hole 19 is opened, the cover plate stirring plate connecting rod 14 is pulled to swing up and down to stir the fish feces settled in the fish feces storage area and discharge it.

[0117] The technical solution in the above embodiment has at least the following technical effects or advantages:

[0118] By such arrangement, the water flow in the lower settling tank 15 is divided into three areas, the linear flow area between the settling tank inlet 1 and the lower settling tank outlet 17, the settling area, and the fish feces storage area. Among them, the settling area includes the main parts of the lower settling tank 15 and the upper settling tank 16, wherein the range of the upper settling tank 16 is between the main water inlet and outlet of the collector and the partition hole cover plate 12, and the function of the upper settling tank 16 is to settle the feces coming out of the main water inlet and outlet 5 of the collector. The speed of the water flowing upward in the lower settling tank 15 is lower than the speed of the fish feces settling.

[0119] 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 water inlet and outlet of the collector and the partition hole cover plate 12. The function of the upper settling tank 16 is mainly to settle the feces coming out of the main water inlet and outlet of the collector.

[0120] The partition hole cover plate 12 and the lower sedimentation tank defecation stirring plate 13 are connected and fixed by the cover plate stirring plate connecting rod 14. The three are integrated and are integrally sleeved outside the overflow pipe, and can be slid up and down and can be easily taken down. When defecation, the cover plate stirring plate connecting rod 14 is slid up and down to stir the fish feces settled in the fish feces storage area and discharge it together with the water.

[0121] Example 5

[0122] On the basis of Example 1, the sedimentation tank is divided into an upper sedimentation tank 16 and a lower sedimentation tank 15 by controlling the sedimentation tank water flow brush 27, and a sedimentation tank stirring plate 28 is provided below the sedimentation tank water flow brush 27. The sedimentation tank water flow brush 27 and the sedimentation tank stirring plate 28 are connected by a stirring plate pull rod 29, and the stirring plate pull rod 29 is mounted on the overflow pipe 11 and the stirring plate pull rod 29 can move up and down along the overflow pipe 11.

[0123] Specifically, as shown in the attached manual Figure 4-7 As shown, this embodiment includes:

[0124] Control brush 27 for water flow in sedimentation tank: The function of brush 27 for water flow in sedimentation tank is to control the uniform flow of water in sedimentation tank, and prevent the water in the tank from generating eddy current and flowing up and down.

[0125] Sedimentation tank stirring plate 28: The sedimentation tank stirring plate 28 is connected to the stirring plate pull rod 29, and swings up and down during defecation to stir up the fish feces settled in the fish feces storage area for discharge.

[0126] Stirring plate pull rod 29: Stirring plate pull rod 29, control sedimentation tank water flow brush 27 and sedimentation tank stirring plate 28 are integrated. Stirring plate pull rod 29 is installed outside overflow pipe 11, can slide up and down, and can be easily taken down.

[0127] Working process:

[0128] During normal operation, the water flow brush 27 of the sedimentation tank is controlled to be about 10 cm away from the bottom of the fish feces sedimentation collector, so that the fish feces and a small amount of flowing water can enter the sedimentation tank through the sedimentation tank inlet 1. The fish feces out of the sedimentation tank inlet 1 settle downward and enter the fish feces storage area. The water out of the sedimentation tank inlet 1 flows upward through the gap between the sedimentation tank water flow brush 27 and the side wall of the sedimentation tank, flows out of the sedimentation tank, and enters the upper part of the fish feces sedimentation collector.

[0129] The technical solution in the above embodiment has at least the following technical effects or advantages:

[0130] The function of the brush 27 for controlling the water flow of the sedimentation tank is to control the uniform flow of water in the sedimentation tank, and prevent the water in the tank from generating eddies and flowing up and down. The problem of water surging upward is solved by providing the brush 27 for controlling the water flow of the sedimentation tank, and at the same time, it can absorb some tiny suspended particles. The distance between the end of the brush 27 for controlling the water flow of the sedimentation tank and the side wall of the fish feces sedimentation collector is 0.45-0.55 cm, so as to prevent the brush from being stuck by nitrifying bacteria and preventing the water from flowing upward.

[0131] Example 6

[0132] On the basis of the first embodiment, the side wall of the sedimentation tank is provided with a water flow control brush 30, and the water flow control brush 30 is divided into two groups, which are respectively arranged on two adjacent side walls of the fish feces sedimentation collector.

[0133] Specifically, as shown in the attached manual Figure 8-9 As shown, this embodiment includes: water flow control brushes 30: two groups of water flow control brushes 30 are respectively arranged on two adjacent side walls of the fish feces sedimentation collector.

[0134] Working process:

[0135] After the fish excrement and flowing water enter the sedimentation tank through the sedimentation tank inlet 1, the space becomes larger and the flow rate becomes slower. The fish excrement settles downward and enters the fish excrement storage area. The flowing water flows upward, passes through the gap between the water flow control brush 30 and the side wall of the sedimentation tank and the water outlet not covered by the water flow control brush 30, flows out of the sedimentation tank, and enters the upper part of the fish excrement sedimentation collector. The water flow control brush 30 can absorb the suspended matter in the water entering the sedimentation tank to prevent the water in the sedimentation tank from surging up and down. It is convenient to use a long rod to clean the brush externally and enter the sedimentation tank to clean every corner.

[0136] The water flow control brush 30 not only absorbs the suspended matter in the water, but also serves as a partition between the lower settling tank 15 and the upper settling tank 16 to prevent the water in the settling tank from surging up and down. Since a large water outlet gap is left at the corners, it is convenient for the water in the lower settling tank 15 to flow out after the small gap is blocked by suspended matter. The water flow control brush 30 is used as a partition to facilitate the long-arm cleaning brush to enter the lower settling tank 15 to clean every corner.

[0137] The technical solution in the above embodiment has at least the following technical effects or advantages:

[0138] The water flow control brush 30 solves the problem of water surging upwards while avoiding the problem of uneven brush distribution.

[0139] Example 7

[0140] In the present embodiment, the third embodiment is improved by changing the upper narrow and lower wide sedimentation tank fish feces storage platform 3 and the upper assisting platform 4 of the feces inlet into two parallel plates.

[0141] The technical solution in the above embodiment has at least the following technical effects or advantages:

[0142] Two parallel plates are used as the sedimentation tank fish feces storage platform 3 and the upper assisting platform 4 of the feces inlet, which makes it easier to manufacture the mold. The rear of the sedimentation tank feces inlet 1 is a rectangular channel with equal cross-sectional area and inclined upward, and the outlet of the channel is higher than the upper edge of the sedimentation tank feces inlet 1.

[0143] Example 8

[0144] The feces inlet 1 of the sedimentation tank and the main water inlet 2 of the collector are arranged on two side plates of the fish feces sedimentation collector.

[0145] At least two sedimentation tank flow rate regulating holes 6 are provided on the side wall 22 of the fish feces sedimentation collector; the flow rate of water in the sedimentation tank can be adjusted by increasing or decreasing the number of the sedimentation tank flow rate regulating holes 6.

[0146] A propeller water pump 7 is installed on the side wall 22 of the fish feces sedimentation collector. The propeller water pump 7 is located below the water level of the aquarium and discharges the water in the sedimentation tank to promote the circulation of water in the fish tank.

[0147] The side wall 22 of the fish feces sedimentation collector is provided with oil-discharging comb holes 20, and the water level of the aquarium is located between the upper edge and the lower edge of the oil-discharging comb holes 20. The diameter of the oil-discharging comb holes 20 is between 0.1 cm and 0.2 cm. The oil floating on the fish tank is discharged to block the fish food.

[0148] The technical solution in the above embodiment has at least the following technical effects or advantages:

[0149] The propeller water pump 7 is installed on the side of the fish feces sedimentation collector to discharge the water in the fish feces sedimentation collector, promote the water in the fish tank to circulate, promote the fish feces to flow to the sedimentation tank inlet 1, and suck the fish feces into the sedimentation tank. Most of the flowing water is sucked into the collector main water inlet 2 and flows back into the fish feces sedimentation collector to form a water cycle. In this embodiment, a propeller water pump 7 with very low power replaces part of the work of the submersible pump, reducing the power, noise and power consumption of most submersible pumps.

[0150] Example 9

[0151] The overflow pipe outlet 10 of the overflow pipe 11 of the aquarium is connected to the biochemical adsorption tank 25, and the biochemical adsorption tank 25 is connected to the biochemical tank 24. The submersible pump 23 transports the water outlet of 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 feces sedimentation collector are located at both ends of the aquarium, and the overflow pipe inlet 9 of the overflow pipe 11 is located in the fish feces sedimentation collector.

[0152] The biochemical tank 24 is filled with biochemical materials such as ceramic rods and ceramic balls to produce nitrifying bacteria to treat organic matter in the water. The biochemical adsorption tank 25 is filled with biochemical cotton to produce nitrifying bacteria to adsorb tiny suspended matter in the water to treat organic matter in the water.

[0153] In summary, the utility model provides a fish feces sedimentation collector and a filter-free ecological fish tank.
