Description

Technical Field

[0001] The invention relates to the field of fish tank water circulation, in particular to a fish tank water circulation system with separation and sedimentation functions. Background Art

[0002] In modern life, people like to raise fish in their offices or homes as ornaments to improve the quality of the working and living environment. In order to keep the fish healthy and beautiful, it is necessary to clean the fish feces and change the water regularly. This process is cumbersome, labor-intensive, and easy to forget, resulting in turbid water in the fish tank, fish illness, and even death, which does not achieve the desired viewing effect.

[0003] In the prior art, a drainage device is usually arranged in the fish tank, and the water to be discharged from the fish tank is separated into water (most of the water in the fish tank that needs to be discharged) and a mixed liquid of fish feces (including fish feces and a small amount of water) through the drainage device, and then discharged from the fish tank. After that, the water is circulated and enters the fish tank again, while the mixed liquid of fish feces is discharged as waste liquid, thereby realizing the purification cycle of the fish tank water.

[0004] However, there is some water in the fish feces mixture, which will be discharged as waste liquid together with the fish feces. The whole circulation process will cause the water in the fish tank to continue to decrease, so it is necessary to frequently add water to the fish tank. The existing automatic water replenishing device is expensive and is commonly used in high-end water tanks, while ordinary fish tanks are generally replenished with water manually, so customers who purchase fish tanks are required to regularly replenish water, which brings a lot of inconvenience to customers.

[0005] Moreover, discharging the fish feces mixture as waste liquid will waste a lot of water resources and cause environmental pollution. Summary of the invention

[0006] The purpose of the present invention is to provide a fish tank water circulation system with separation and sedimentation function, which can not only separate the water liquid and the fish excrement mixed liquid to be discharged from the fish tank, but also precipitate and separate the water of the fish excrement mixed liquid, and replenish the separated water into the fish tank, thereby greatly reducing the number of times and the amount of water replenishment for customers, thereby improving customer satisfaction. Moreover, the fish excrement mixed liquid is discharged after precipitation and separation, which reduces the waste of water resources and thus reduces environmental pollution.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A fish tank water circulation system with separation and sedimentation functions comprises a tank body, a fish feces separation component is arranged on the tank body, a sedimentation component and a water inlet component are arranged outside the tank body, wherein:

[0009] The fish excrement separation component is used to separate the liquid in the cylinder into a first water liquid and a fish excrement mixed liquid, and discharge the first water liquid to the water inlet component, and discharge the fish excrement mixed liquid to the sedimentation component, wherein the fish excrement mixed liquid includes fish excrement and a second water liquid;

[0010] The sedimentation component is used to sediment the fish excrement in the fish excrement mixed liquid, and discharge the second water liquid in the fish excrement mixed liquid into the water inlet component;

[0011] The water inlet assembly is used to receive the first water liquid and / or the second water liquid, and input the first water liquid and / or the second water liquid into the cylinder.

[0012] The present application describes a fish tank water circulation system with separation and sedimentation functions, in which the water in the tank body maintains a dynamic balance. At this time, the water in the tank body that needs to be discharged is first separated into a first water liquid and a fish feces mixed liquid by a fish feces separation component. Afterwards, the first water liquid separated by the fish feces separation component enters the water inlet component, and then the first water liquid is replenished into the fish tank through the water inlet component to realize water circulation in the fish tank.

[0013] The separated fish excrement mixture is discharged into the sedimentation component, so that the fish excrement in the fish excrement mixture is precipitated into the sedimentation component, and the second water in the fish excrement mixture is discharged into the water inlet component, and then the second water is replenished into the fish tank through the water inlet component for further use.

[0014] In the entire water circulation process of the above scheme, most of the water and the fish feces mixture are separated by the fish feces separation component, and then the fish feces mixture is treated again by the sedimentation component, and the treated second water liquid is replenished into the fish tank, so that the circulation system described in the present application, except for some water wasted artificially when cleaning the sedimentation component that has precipitated in the sedimentation component, will not discharge water to the outside in other processes, thereby greatly reducing the number of times and the amount of water replenishment for customers on a regular basis, thereby improving customer satisfaction. Moreover, the fish feces mixture is discharged after sedimentation and separation, which reduces the waste of water resources and thus reduces environmental pollution.

[0015] Preferably, the second water liquid is discharged into the main filter assembly or the water inlet assembly through a first water outlet pipe, the first water outlet pipe is connected to the sedimentation assembly, a float switch is provided on the first water outlet pipe, and the float switch is located in the main filter assembly or the water inlet assembly.

[0016] When the water inlet component fails and cannot input the first water liquid and / or the second water liquid into the cylinder body, the sedimentation component will continue to discharge the second water liquid into the main filter component or the water inlet component, causing the water in the fish tank to continue to decrease, thereby affecting the safety of the fish in the fish tank. Therefore, a float switch is provided on the first water outlet pipe, and the float switch is located in the main filter component or the water inlet component. When the water remaining in the main filter component or the water inlet component exceeds a certain amount, the liquid level will trigger the float switch, and the float switch will be closed, so that the water in the sedimentation component cannot be discharged, and the fish feces mixture of the fish feces separation component cannot be discharged into the sedimentation component, thereby ensuring the height of the water in the fish tank from the passage of the fish feces mixture.

[0017] Preferably, a main filter assembly is provided upstream of the water inlet assembly.

[0018] The fish excrement separation component is used to discharge the first water liquid into the main filter component or the water inlet component;

[0019] The sedimentation component is used to discharge the second water liquid into the main filtering component or the water inlet component;

[0020] The main filter assembly is used to filter the first water liquid and / or the second water liquid, and discharge the filtered first water liquid and / or the second water liquid into the water inlet assembly.

[0021] The first water liquid separated by the fish feces separation component enters the main filtering component for filtration, and after obtaining the first water liquid that can meet the circulation requirements, it is discharged into the water inlet component, and then the first water liquid is replenished into the fish tank through the water inlet component to realize the water circulation of the fish tank;

[0022] In the sedimentation component, the second water liquid in the fish feces mixture is directly discharged into the water inlet component, or discharged into the main filter component for filtration to obtain the second water liquid that better meets the circulation requirements, and then discharged into the water inlet component, and then the second water liquid is replenished into the fish tank through the water inlet component for further use.

[0023] In the above scheme, if the fish feces separation component works well and the separated first water liquid can meet the circulation requirements, the first water liquid separated by the fish feces separation component can also be directly discharged into the water inlet component, and then the first water liquid is replenished into the fish tank through the water inlet component to realize the water circulation of the fish tank.

[0024] Preferably, the sedimentation component includes a sedimentation tank, and a water inlet and a water outlet are arranged on the top of the sedimentation tank, the water inlet and the water outlet are both connected to the sedimentation tank, the fish feces mixture enters the sedimentation tank through the water inlet, and the second water liquid is discharged from the sedimentation tank through the water outlet.

[0026] A baffle is arranged inside the annular side wall, and the fish excrement mixture can enter the top cover through the water inlet and fall on the baffle, which plays a role in slowing down the speed of the fish excrement mixture, so as to avoid the problem that the fish excrement mixture impacts the sedimentation bin and washes up the fish excrement settled in the sedimentation bin, thereby playing the effect of slowing down the flow rate of the fish excrement mixture.

[0027] Afterwards, the fish excrement mixture flows to the sedimentation bin through the gap between the baffle and the side wall. Since the water inlet is arranged on the annular side wall and the side of the baffle faces the end cover, the fish excrement mixture entering the top cover from the water inlet falls on the baffle in the form of a parabola. Compared with the fish excrement in the fish excrement mixture directly impacting the obstruction, the speed at which the fish excrement mixture falls on the baffle is much lower than the speed at which the fish excrement mixture directly impacts the obstruction, which greatly reduces the speed at which the fish excrement in the fish excrement mixture contacts the baffle, thereby greatly reducing the probability of the fish excrement being crushed when the fish excrement contacts the baffle.

[0028] Preferably, a water pipe is provided inside the annular side wall, the water pipe is respectively connected with the water outlet and the sedimentation bin, and the baffle is sleeved outside the water pipe.

[0029] Since there is a gap between the baffle and the annular side wall for fish excrement to pass through, a water pipe is arranged in the cavity so that the baffle is sleeved outside the water pipe, thereby connecting the middle parts of the water pipe and the baffle, and the connection will not interfere with the setting of the gap.

[0030] Preferably, a discharge device for discharging fish excrement from the sedimentation bin is provided at the bottom of the sedimentation bin, and a valve is provided on the discharge device.

[0031] When the amount of fish excrement settled in the sedimentation bin reaches a certain amount, the valve on the discharge device can be opened to clean the fish excrement out of the sedimentation bin. The whole process is simple and convenient.

[0032] Preferably, the sedimentation component also includes at least one level of filtering device, the sedimentation tank and the filtering device are arranged in series, and the second water liquid passes through the sedimentation tank and the filtering device in sequence and is discharged into the main filtering component or the water inlet component.

[0033] During the sedimentation of fish feces, in order to prevent individual fish feces from overflowing with the second water liquid outside the sedimentation bin and entering the water inlet component, thereby affecting the water inlet component, at least one level of filtering device is connected in series downstream of the sedimentation bin to ensure that the second water liquid entering the water inlet component is clean and free of fish feces impurities.

[0034] Preferably, the fish excrement separation assembly comprises:

[0035] A second water outlet pipe is vertically arranged, the second water outlet pipe runs through the bottom plate of the cylinder body, and the first water liquid is discharged into the water inlet assembly through the second water outlet pipe.

[0036] A separation tube is sleeved outside the second water outlet pipeline, a separation chamber is formed between the separation tube and the second water outlet pipeline, a first sewage outlet is provided at the bottom of the separation chamber, the first sewage outlet is used for the separation chamber to be connected with the outside of the separation tube, the first sewage outlet is provided inside the cylinder body, and the bottom of the separation chamber is connected with the sedimentation component.

[0037] When in use, the second water outlet pipe is arranged vertically, and the separation pipe is sleeved on the outside of the second water outlet pipe. The water at the top of the separation chamber enters the second water outlet pipe from the upper end of the second water outlet pipe to be discharged to the main filter assembly through the second water outlet pipe, which will generate an upward suction inside the separation chamber, so that the first sewage outlet will generate a suction from the outside of the separation pipe to the inside of the separation pipe, and the water and fish feces in the fish tank will be sucked into the separation chamber through the first sewage outlet. At this time, the water entering the separation chamber from the first sewage outlet rises due to the suction, but the density of fish feces is greater than that of water, so the fish feces will gather at the bottom of the separation chamber. The bottom of the separation chamber is connected with the sedimentation assembly, and the fish feces gathered at the bottom of the separation chamber and a part of the water form a fish feces mixed liquid and are discharged into the sedimentation assembly, so as to achieve the purpose of separating the water to be discharged from the fish tank into the first water liquid and the fish feces mixed liquid.

[0038] Preferably, a filter tube is sleeved on the outside of the separation tube, the top surface of the second water outlet pipe and the top surface of the separation tube are both lower than the top surface of the filter tube, a collecting chamber is formed between the filter tube and the separation tube, a second sewage outlet connected to the outside of the filter tube is provided at the bottom of the collecting chamber, the second sewage outlet is located on the inside of the cylinder body, the first sewage outlet connects the separation chamber and the collecting chamber, and the bottom of the separation chamber is connected to the sedimentation assembly. The present application describes a fish tank water circulation system with separation and sedimentation functions, wherein a filter tube, a separation tube and a second water outlet pipe are sequentially installed, the second water outlet pipe is used for water outlet, a second sewage outlet connected to the outside of the filter tube is provided at the bottom of the collecting chamber, when in use, water and fish feces on the outside of the filter tube are sucked into the collecting chamber through the second sewage outlet, the top surface of the second water outlet pipe is lower than the top surface of the filter tube, so that the water level in the fish tank is higher than the water outlet surface of the second water outlet pipe, so that there is a liquid level difference between the water in the filter tube and the water outside the filter tube, the first sewage outlet connected to the collecting chamber is provided at the bottom of the separation chamber, because the separation chamber is closer to the second water outlet pipe, the water in the separation chamber enters the second water outlet pipe faster, and at the same time, due to the liquid level difference between the inside and outside of the filter tube, the first sewage outlet will generate water from the collecting chamber The suction force to the separation chamber will suck the fish feces in the collection chamber into the separation chamber. Since the density of fish feces is greater than that of water, it will gather at the bottom of the separation chamber. Therefore, the water to be discharged enters the second water outlet pipe through the upper part of the second water outlet pipe and is discharged to the main filter component, thereby achieving the purpose of separating and discharging most of the fish feces in the fish tank from the water, greatly reducing the phenomenon that the fish feces are repeatedly brushed and crushed by the discharged water and return to the fish tank in a state close to liquid, thereby destroying the living environment of the fish. At the same time, the filtration load of the physical filtration layer and the biological filtration layer in the main filter component is greatly reduced, the service life of the filtration layer is extended, and the use cost is greatly reduced. The bottom of the separation chamber is connected with the sedimentation component, so that the fish feces gathered at the bottom of the separation chamber and a part of the water form a fish feces mixed liquid and are discharged into the sedimentation component for sedimentation.

[0039] Preferably, the water inlet assembly includes a water inlet pipe, a water storage tank and a circulating water pump located in the water storage tank, the water storage tank is used to hold the first water liquid and / or the second water liquid, the output end of the circulating water pump is connected to the water inlet pipe, and the first water liquid and / or the second water liquid enters the cylinder body through the water inlet pipe.

[0040] After the first water liquid and / or the second water liquid enters the water storage tank, it is driven to the water inlet pipe by a circulating water pump and enters the cylinder body through the water inlet pipe to complete the entire circulation.

[0041] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0042] 1. The present application discloses a fish tank water circulation system with separation and sedimentation functions, which separates most of the water and the fish feces mixture through a fish feces separation component, and then processes the fish feces mixture again through a sedimentation component, and replenishes the treated second water liquid into the fish tank, so that the circulation system described in the present application, except for the artificial waste of some water when cleaning the sedimentation component that has settled in the sedimentation component, will not discharge water to the outside in other processes, thereby greatly reducing the number of times and the amount of water replenishment by customers on a regular basis, thereby improving customer satisfaction. Moreover, the fish feces mixture is discharged after sedimentation and separation, which reduces the waste of water resources and thus reduces environmental pollution.

[0043] 2. The present application discloses a fish tank water circulation system with separation and sedimentation functions. When the water inlet component fails and cannot input the first water liquid and / or the second water liquid into the tank body, the sedimentation component will continue to discharge the second water liquid into the main filter component or the water inlet component, causing the water in the fish tank to continue to decrease, thereby affecting the safety of the fish in the fish tank. Therefore, a float switch is provided on the first water outlet pipe, and the float switch is located in the main filter component or the water inlet component. When the water retained in the main filter component or the water inlet component exceeds a certain amount, the liquid level will trigger the float switch, and the float switch will be closed, so that the water in the sedimentation component cannot be discharged, and the fish feces mixture of the fish feces separation component cannot be discharged into the sedimentation component, thereby ensuring the height of the water in the fish tank from the passage of the fish feces mixture.

[0044] 3. The present application discloses a fish tank water circulation system with separation and sedimentation functions, wherein a baffle is arranged inside the annular side wall, and the fish feces mixture can enter the top cover through the water inlet and fall on the baffle, thereby slowing down the speed of the fish feces mixture, so as to avoid the problem that the fish feces mixture impacts the sedimentation bin and washes up the settled fish feces in the sedimentation bin, thereby slowing down the flow rate of the fish feces mixture.

[0045] 4. In the fish tank water circulation system with separation and sedimentation functions of the present application, the water inlet is arranged on the annular side wall, and the side of the baffle plate faces the end cover, so that the fish feces mixture entering the top cover from the water inlet falls on the baffle plate in the form of a parabola. Compared with the fish feces in the fish feces mixture directly impacting the barrier, the speed at which the fish feces mixture falls on the baffle plate is much lower than the speed at which the fish feces mixture directly impacts the barrier, which greatly reduces the speed at which the fish feces in the fish feces mixture contacts the baffle plate, thereby greatly reducing the probability of the fish feces being crushed when the fish feces contacts the baffle plate.

[0046] 5. The fish tank water circulation system with separation and sedimentation function of the present application can open the valve on the discharge device to clean the fish feces out of the sedimentation bin when the amount of fish feces settled in the sedimentation bin reaches a certain amount. The whole process is simple and convenient.

DETAILED DESCRIPTION

[0055] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0056] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0057] Example 1

[0058] like Figure 1-5 As shown, a fish tank water circulation system with separation and sedimentation functions described in this embodiment includes a cylinder body 4, on which a fish feces separation component 2 is arranged, and a main filter component 3, a sedimentation component 1 and a water inlet component 5 are arranged outside the cylinder body 4. The basic purpose of the water circulation system is to maintain dynamic balance of the water in the cylinder body 4 and to discharge the fish feces in the cylinder body 4 to the outside of the cylinder body 4.

[0059] When in use, the second water outlet pipe 21 is vertically arranged in the cylinder body 4 and passes through the bottom plate 41 of the cylinder body 4. The separation pipe 22 is sleeved on the outside of the second water outlet pipe 21. A separation chamber 23 is formed between the separation pipe 22 and the second water outlet pipe 21. Water at the top of the separation chamber 23 enters the second water outlet pipe 21 from the upper end of the second water outlet pipe 21 to become the first water liquid. The first water liquid is discharged to the main filter assembly 3 through the second water outlet pipe 21 for filtration, and then enters the water storage tank 51.

[0060] The separation chamber 23 is provided with a first sewage outlet 25 at the bottom thereof. The first sewage outlet 25 is used to connect the separation chamber 23 with the outside of the separation tube 22. The first sewage outlet 25 is provided on the inner side of the cylinder body 4. The water at the top of the separation chamber 23 enters the second water outlet pipe 21 from the upper end of the second water outlet pipe 21, which will generate an upward suction force inside the separation chamber 23, so that the first sewage outlet 25 will generate a suction force from the outside of the separation tube 22 to the inside of the separation tube 22, and the water and fish feces in the fish tank will be sucked into the separation chamber 23 through the first sewage outlet 25. At this time, the water entering the separation chamber 23 from the first sewage outlet 25 rises due to the suction force, but The density of fish feces is greater than that of water, so the fish feces will gather at the bottom of the separation chamber 23, and the bottom of the separation chamber 23 is connected to the sedimentation component 1. The fish feces gathered at the bottom of the separation chamber 23 and a part of the water form a fish feces mixed liquid and are discharged to the sedimentation component 1, so as to achieve the purpose of separating the water to be discharged from the fish tank into a first water liquid and a fish feces mixed liquid, wherein the fish feces mixed liquid includes fish feces and a second water liquid. In the separation chamber 23, very few fish feces will rise with the water. At this time, a filter screen 28 can be set between the separation pipe 22 and the second water outlet pipe 21 to prevent the fish feces from rising, so as to better ensure the effect of separating the fish feces and the first water liquid.

[0061] The sedimentation assembly 1 includes a sedimentation bin 11, a top cover 12 is connected to the top of the sedimentation bin 11, the top cover 12 has an annular side wall 123, one end of the annular side wall 123 is sealed and connected to an end cover 126, the other end of the annular side wall 123 is open and connected to the sedimentation bin 11, and the annular side wall 123 is sealed and connected to the sedimentation bin 11, or is integrally molded and demoulded from the bottom of the sedimentation bin to ensure sealing, the annular side wall 123 is provided with a water inlet 121 and a water outlet 122, and the preferred choice is the water inlet 1 The water inlet 121 and the water outlet 122 are arranged opposite to each other, do not interfere with each other, and are easy to take over. The water inlet 121 is located downstream of the separation chamber 23 and is connected to the separation chamber 23. A baffle 124 is arranged inside the annular side wall 123. The water inlet 121 is located between the baffle 124 and the end cover 126. There is a gap 127 between the baffle 124 and the annular side wall 123 for fish feces to pass through. The gap 127 is connected to the water inlet 121, and the side of the baffle 124 faces the end cover 126. A water pipe 125 is arranged inside the annular side wall 123. The two ends of the water pipe 125 are respectively connected to the water outlet 122 and the sedimentation bin. The baffle 124 is sleeved outside the water pipe 125 so that the water pipe 125 is connected to the middle of the baffle 124, and the connection does not interfere with the setting of the gap 127.

[0062] The fish excrement mixture enters the top cover 12 from the water inlet 121 and falls on the baffle 124 in the form of a parabola, so that the baffle 124 slows down the speed of the fish excrement mixture to prevent the fish excrement mixture from impacting the sedimentation bin 11 and lifting the settled fish excrement in the sedimentation bin 11, thereby slowing down the flow rate of the fish excrement mixture.

[0063] The fish excrement mixture then flows to the sedimentation bin 11 through the gap between the baffle 124 and the side wall. Since the water inlet 121 is arranged on the annular side wall 123, and the side of the baffle 124 faces the end cover 126, the fish excrement mixture entering the top cover 12 from the water inlet 121 falls on the baffle 124 in the form of a parabola. Compared with the fish excrement in the fish excrement mixture directly impacting the obstruction, the speed at which the fish excrement mixture falls on the baffle 124 is much lower than the speed at which the fish excrement mixture directly impacts the obstruction, which greatly reduces the speed at which the fish excrement in the fish excrement mixture contacts the baffle 124, thereby greatly reducing the probability of the fish excrement being crushed when the fish excrement contacts the baffle 124.

[0064] After the fish excrement mixture enters the sedimentation tank 11, since the fish excrement density in the fish excrement mixture is greater than the density of the second water liquid, the fish excrement will settle to the bottom of the sedimentation tank 11, and the second water liquid enters the water pipe 125 and flows out from the water outlet 122, and then is discharged to the main filter component 3 or the water inlet component 5 through the first water outlet pipeline 6.

[0065] A discharge device 111 for discharging fish excrement from the sedimentation bin 11 is provided at the bottom of the sedimentation bin 11. A valve 112 is provided on the discharge device 111. When the amount of fish excrement settled in the sedimentation bin 11 reaches a certain amount, the valve 112 on the discharge device 111 can be opened to clean the fish excrement out of the sedimentation bin 11. The whole process is simple and convenient.

[0066] After the first water liquid and / or the second water liquid enters the water storage tank 51, a circulating water pump 52 is provided in the water storage tank 51, and the output end of the circulating water pump 52 is connected to the water inlet pipe 53. The first water liquid and / or the second water liquid can be driven to the water inlet pipe 53 through the circulating water pump 52, and enter the cylinder body 4 through the water inlet pipe 53 to realize the whole circulation.

[0067] In the above scheme, the water separated by the fish feces separation component 2 can be directly discharged into the water inlet component 5, or discharged into the main filter component 3, and then discharged into the water inlet component 5 after being filtered by the main filter component 3;

[0068] The second water liquid passing through the sedimentation component 1 can be directly discharged into the water inlet component 5 , or can be discharged into the main filter component 3 , and then discharged into the water inlet component 5 after being filtered by the main filter component 3 .

[0069] On the basis of the above, a further preferred method is that when the water inlet component 5 fails and cannot input the first water liquid and / or the second water liquid into the cylinder body 4, since the second water outlet pipe 21 is vertically arranged and has a certain height in the cylinder body 4, when the water level in the cylinder body 4 is lower than the height of the top surface of the second water outlet pipe 21, the second water outlet pipe 21 will no longer drain water, but the fish feces mixture at the bottom of the separation chamber 23 will continue to be discharged into the sedimentation component 1, causing the water in the fish tank to continue to decrease, so as to affect the safety of the fish in the fish tank, so a float switch 61 is set on the first water outlet pipe 6, The float switch 61 is located in the main filter component 3 or the water inlet component 5, and the float switch 61 is located in the main filter component 3 or the water inlet component 5. When the water retained in the main filter component 3 or the water inlet component 5 exceeds a certain amount, the liquid level will trigger the float switch 61, and the float switch is closed, so that the water in the sedimentation component 1 cannot be discharged, and the fish feces mixture of the fish feces separation component 2 cannot be discharged into the sedimentation component 1, and the height of the water in the fish tank is ensured from the passage of the fish feces mixture. It cooperates with the second water outlet pipe 21 to ensure the height of the water in the fish tank.

[0070] On the basis of the above, a further preferred method is that during the sedimentation of fish feces, in order to prevent individual fish feces from overflowing with the second water liquid to the outside of the sedimentation bin 11 and entering the water inlet component 5, causing its impact on the water inlet component 5, at least one level of filtering device 13 is connected in series downstream of the sedimentation bin 11, and the second water liquid passes through the sedimentation bin 11 and the filtering device 13 in turn and is discharged into the main filtering component 3 or the water inlet component 5, thereby ensuring that the second water liquid entering the water inlet component 5 is clean and free of fish feces impurities.

[0071] The present application describes a fish tank water circulation system with separation and sedimentation functions. At this time, the water to be discharged from the tank body 4 is first separated into a first water liquid and a fish feces mixed liquid by the fish feces separation component 2. After that, the first water liquid separated by the fish feces separation component 2 enters the main filter component 3 for filtration. After obtaining the first water liquid that can meet the circulation requirements, it is discharged into the water inlet component 5, and then the first water liquid is replenished into the fish tank through the water inlet component 5 to realize the water circulation of the fish tank.

[0072] The separated fish feces mixture is discharged into the sedimentation component 1, so that the fish feces in the fish feces mixture is precipitated into the sedimentation component 1, and the second water in the fish feces mixture is directly discharged into the water inlet component 5, or discharged into the main filter component 3 for filtration, and then discharged into the water inlet component 5, and then the second water is replenished into the fish tank through the water inlet component 5 for further use.

[0073] In the entire water circulation process of the above scheme, most of the water and the fish feces mixture are separated by the fish feces separation component 2, and then the fish feces mixture is treated again by the sedimentation component 1, and the treated second water liquid is replenished into the fish tank, so that the circulation system described in the present application, except for some water wasted artificially when cleaning the sedimentation component 1 that has precipitated in the sedimentation component 1, will not discharge water to the outside in other processes, thereby greatly reducing the number of times and the amount of water replenishment for customers on a regular basis, thereby improving customer satisfaction, and the fish feces mixture is discharged after sedimentation and separation, which reduces the waste of water resources and thus reduces environmental pollution.

[0074] Example 2

[0075] like Figure 6 As shown, the fish tank water circulation system with separation and sedimentation functions described in this embodiment is different from that in Embodiment 1 in that a filter tube 26 is sleeved on the outside of the separation tube 22, the top surface of the second water outlet pipeline 21 and the top surface of the separation tube 22 are both lower than the top surface of the filter tube 26, a collecting chamber 24 is formed between the filter tube 26 and the separation tube 22, a second sewage outlet 27 communicating with the outside of the filter tube 26 is provided at the bottom of the collecting chamber 24, the second sewage outlet 27 is located on the inner side of the cylinder body 4, the first sewage outlet 25 communicates with the separation chamber 23 and the collecting chamber 24, the bottom of the separation chamber 23 is connected with the sedimentation component 1, and in actual production, the top surface of the separation tube 22 can be 0mm-10mm higher than the top surface of the second water outlet pipeline 21, or it can be flush, or the top surface of the second water outlet pipeline 21 can be 0mm-10mm higher than the top surface of the separation tube 22.

[0076] When in use, the water and fish feces outside the filter tube 26 are sucked into the collection chamber 24 through the second sewage outlet 27. The top surface of the second water outlet pipe 21 and the top surface of the separation pipe 22 are both lower than the top surface of the filter tube 26. The water at the top of the separation chamber 23 and the collection chamber 24 enters the second water outlet pipe 21 through the top surface of the second water outlet pipe 21 to be discharged from the fish tank. The second water outlet pipe 21 determines the water level in the fish tank when the circulation system described in the present application is not in operation.

[0077] At the same time, the water level in the fish tank is higher than the water outlet surface of the second water outlet pipe 21, so that there is a liquid level difference between the water in the filter tube 26 and the water outside the filter tube 26, so that the second sewage outlet 27 generates suction from the outside of the filter tube 26 to the collection chamber 24, so that the water outside the filter tube 26 and the fish feces can be sucked into the collection chamber 24; the bottom of the separation chamber 23 is provided with a first sewage outlet 25 connected to the collection chamber 24, because the separation chamber 23 is closer to the second water outlet pipe 21, the water in the separation chamber 23 enters the second water outlet pipe 21 faster from the top of the second water outlet pipe 21, so the first sewage outlet 25 generates a suction force from the collection chamber 24 to the separation chamber 23. The suction force will suck the fish feces in the collection chamber 24 into the separation chamber 23. Since the density of fish feces is greater than that of water, it will gather at the bottom of the separation chamber 23. Therefore, the water to be discharged enters the second water outlet pipe 21 through the second water outlet pipe 21 and is discharged to the main filter assembly 3, thereby achieving the purpose of separating and discharging most of the fish feces in the fish tank from the water, greatly reducing the phenomenon that the fish feces are repeatedly brushed and crushed by the discharged water and return to the fish tank in a state close to liquid, destroying the living environment of the fish. At the same time, the filtration load of the physical filter layer and the biological filter layer in the main filter assembly is greatly reduced, and the service life of the filter layer is extended, and its use cost is greatly reduced. The bottom of the separation chamber 23 is connected to the water inlet 121 of the precipitation assembly 1, so that the fish feces gathered at the bottom of the separation chamber 23 and a part of the water form a fish feces mixed liquid and are discharged into the precipitation assembly 1 for precipitation.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
