Description

Technical Field

[0001] The present invention belongs to the technical field of aquarium fish tanks, and particularly relates to an operating system for a micro-overflow bottom filter fish tank. Background Art

[0002] The existing bottom filter fish tanks are roughly in several situations:

[0003] 1. Using a closed filter barrel instead of a filter bottom tank, there is no overflow, so there is no treatment for the oil film on the surface water.

[0004] 2. For a fish tank without pipelines in the tank, a large-flow float valve is installed in the bottom tank to control the water flow rate for draining, and there is also no overflow.

[0005] 3. For overflow fish tanks such as three-pipe overflow, corner overflow, and side overflow, fish feces cross the overflow plate from bottom to top into the filter bottom tank, and the fish feces are broken and pollute the water quality.

[0006] 4. For large fish tank filtration, a closed filter barrel is used to handle fish feces + an open bottom tank is used to handle the oil film. The disadvantage is that at least two water pumps form their own circulation systems respectively, and the pipelines are complex and cannot be popularized for the general public to raise fish.

[0007] 5. In recent years, the fish toilet used can separate part of the fish feces, but the sewage discharge area has always been stagnant water, and the filtration effect is greatly reduced.

[0008] For traditional bottom filter fish tanks, either all overflow or there is no overflow, lacking a method to separately filter fish feces, oil film, or bottom water and surface water with one water pump. Summary of the Invention

[0009] The purpose of the present invention is to solve the above problems and provide an operating system for a micro-overflow bottom filter fish tank.

[0010] To solve the above technical problems, the technical solution adopted by the present invention is:

[0011] An operating system for a micro-overflow bottom filter fish tank, including a bottom tank, an ornamental tank, a micro-overflow, a feces separator, and a water pump. The feces separator and the bottom tank are located below the ornamental tank. The micro-overflow is arranged on the ornamental tank, and its lower end extends into the bottom tank. A bottom-blow water outlet joint and a sewage drain water joint are arranged on the bottom surface of the ornamental tank. The sewage drain water joint is connected to the water inlet of the feces separator. The water pump is located in the bottom tank, and its water outlet end is connected to the bottom-blow water outlet joint through a three-way pipe, and a water inlet check valve is arranged between the three-way pipe and the bottom-blow water outlet joint.

[0012] It further includes a water drain check valve. The water inlet of the water drain check valve is connected to the water outlet of the feces separator. The pressure control water inlet is connected to the water outlet end of the water pump through a three-way pipe, and the water outlet extends into the bottom tank.

[0013] All the above connections are made by water pipes.

[0014] Further, the drain check valve includes a valve body, a water inlet end, a control end, and a valve core. The water inlet end and the control end are respectively connected to the upper and lower ends of the valve body by threads. The water inlet end and the interior of the valve body form an upper valve chamber, and the control end and the interior of the valve body form a lower valve chamber. The upper and lower edges of the upper valve chamber and the lower valve chamber are both conical surfaces. A central through hole is vertically opened in the middle of the valve body, and a water outlet is opened in the middle of the side wall of the valve body. A water inlet is opened in the middle of the top surface of the water inlet end, and a positioning piece is coaxially arranged inside the water inlet. A pressure control water inlet is opened in the middle of the bottom surface of the control end. The valve core includes an upper valve ball, a valve core connecting rod, and a lower valve ball. The upper valve ball is located in the upper valve chamber, the lower valve ball is located in the lower valve chamber, the valve core connecting rod is located on the central axis of the central through hole, the upper end passes through the upper valve ball and extends into the positioning hole of the positioning piece, and the lower end is inserted into the lower valve ball.

[0015] Further, sealing rings are provided at the connections between the valve body and the water inlet end and the control end.

[0016] Further, the upper valve ball and the lower valve ball are made of rubber-like elastic materials.

[0017] Further, a first regulating valve is provided at the lower end of the micro-overflow, a second regulating valve is provided between the water pump and the bottom blowing water outlet joint, a third regulating valve is provided between the feces separator and the drain check valve, a fourth regulating valve is provided between the feces separator and the sewage drain joint, and a sewage discharge valve is provided at the sewage discharge port of the feces separator.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The present invention adopts a self-designed drain check valve, which realizes the separate filtration of the bottom water and the surface water in the fish tank; taking into account the advantages that the feces in the overflow fish tank and the fish tank without internal pipelines directly enter the feces separator, the feces discharge path is short, pollution is reduced, and the filtration performance is improved; making up for the defect that the non-overflow fish tank cannot remove the oil film.

[0020] 2. After using the present invention, the overflow tank and the overflow pipe are much smaller in external dimensions than the traditional ones, with a simple structure, not easy to accumulate dirt, good concealment effect, and greatly improving the ornamental effect.

Specific embodiments

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] As Figures 1-3 shown, a micro-overflow bottom filter fish tank operation system includes a bottom cylinder a1, a viewing cylinder a2, a micro-overflow a3, a feces separator a10 and a water pump a12. The feces separator a10 and the bottom cylinder a1 are located below the viewing cylinder a2. A sewage discharge valve a15 is provided at the sewage discharge port of the feces separator a10. The micro-overflow a3 is arranged on the viewing cylinder a2, and its lower end extends into the bottom cylinder a1. A first regulating valve a6 is provided at the lower end of the micro-overflow a3. A bottom-blow water outlet joint a4 and a sewage drainage joint a5 are provided on the bottom surface of the viewing cylinder a2. The sewage drainage joint a5 is connected to the water inlet of the feces separator a10, and a fourth regulating valve a9 is provided in the middle. The water pump a12 is located in the bottom cylinder a1, and its water outlet end is connected to the bottom-blow water outlet joint a4 through a tee a13. A water inlet check valve a14 is provided between the tee a13 and the bottom-blow water outlet joint a4, and a second regulating valve a7 is provided between the water pump a12 and the bottom-blow water outlet joint a4;

[0029] It further includes a sewage check valve a11. The water inlet b4 of the sewage check valve a11 is connected to the water outlet of the feces separator a10, and a third regulating valve a8 is provided in the middle. The pressure control water inlet b9 is connected to the water outlet end of the water pump a12 through a tee a13, and the water outlet b14 extends into the bottom cylinder a1;

[0030] All the above connections are made by water pipes.

[0031] The water outlet check valve a11 includes a valve body b1, a water inlet end b2, a control end b3 and a valve core. The water inlet end b2 and the control end b3 are respectively connected to the upper and lower ends of the valve body b1 by threads, and sealing rings b15 are provided at the connection parts. The water inlet end b2 and the inside of the valve body b1 form an upper valve cavity b6, and the control end b3 and the inside of the valve body b1 form a lower valve cavity b11. The upper and lower edges of the upper valve cavity b6 and the lower valve cavity b11 are both conical surfaces b13. A central through hole b8 is vertically opened in the middle of the valve body b1, and a water outlet b14 is opened in the middle of the side wall of the valve body b1. A water inlet b4 is opened in the middle of the top surface of the water inlet end b2, and a positioning piece b5 is coaxially provided inside the water inlet b4. A pressure control water inlet b9 is opened in the middle of the bottom surface of the control end b3. The valve core includes an upper valve ball b7, a valve core connecting rod b10 and a lower valve ball b12. The upper valve ball b7 is located in the upper valve cavity b6, the lower valve ball b12 is located in the lower valve cavity b11, and the upper valve ball b7 and the lower valve ball b12 are made of rubber. The valve core connecting rod b10 is located on the central axis of the central through hole b8, the upper end passes through the upper valve ball b7 and extends into the positioning hole of the positioning piece b5, and the lower end is inserted into the lower valve ball b12.

[0032] The upper valve ball b7 and the lower valve ball b12 can also be made of other rubber-like elastic materials.

[0033] The operating principle is as follows:

[0034] The water outlet check valve a11 is closed by the self-weight of the valve core + the static water pressure of the viewing tank a2, and is opened because the water outlet pressure of the water pump a12 is greater than the self-weight of the valve core + the static water pressure of the viewing tank a2.

[0035] When the water pump a12 starts and there is water pressure at the control end of the water outlet check valve a11, the valve core rises to a high position, the lower valve ball b12 is pressed against and closes the upper conical surface b13 of the lower valve cavity b11 to block the water flow of the water pump a12; during the rising process of the lower valve ball b12, only a small amount of the water flow of the water pump a12 leaks through the gap between the lower valve ball b12 and the lower valve cavity b11; at the same time, the upper valve ball b7 rises to the middle position of the upper valve cavity b6, and the water flowing downward passes through the water inlet b4 of the water outlet check valve a11, the gap between the upper valve ball b7 and the upper valve cavity b6, and the central through hole b8, and is discharged from the water outlet b14.

[0036] When the water pump a12 stops and the valve core descends to a low position, the upper valve ball b7 presses against the lower conical surface b13 of the upper valve cavity b6 to block the downward water flow. At the same time, the lower valve ball b12 descends and there is a certain gap with the lower conical surface b13 of the lower valve cavity b11 to ensure that the upper valve ball b7 is in a pressed state with the lower conical surface b13 of the upper valve cavity b6.

[0037] Open the first regulating valve a6, the second regulating valve a7, the third regulating valve a8 and the fourth regulating valve a9 to the half-open state, add water to the bottom cylinder a1, turn on the water pump a12, open the downward check valve a11, the water pumped by the water pump a12 enters the viewing tank a2 through the bottom-blowing water outlet joint a4, and the water in the viewing tank a2 enters the bottom cylinder a1 through the sewage downward joint a5, the fecal separator a10 and the downward check valve a11. Adjust the first regulating valve a6, the second regulating valve a7, the third regulating valve a8 and the fourth regulating valve a9 to gradually raise the water level in the viewing tank a2. When the viewing tank a2 is full of water and overflows, stop adding water to the bottom cylinder a1, and continue to adjust the flow rates of the second regulating valve a7, the third regulating valve a8 and the fourth regulating valve a9 until the flow rates of the bottom-blowing water outlet joint a4, the sewage downward joint a5 and the micro-overflow a3 are appropriate. Adjust the first regulating valve a6 to reduce the noise of the micro-overflow a3 when discharging water.

[0038] Turn off the water pump a12, the water discharge from the bottom-blowing water outlet joint a4 stops, the downward check valve a11 closes, the water discharge from the sewage downward joint a5 stops, and the water discharge of the micro-overflow a3 stops after a period of time.

[0039] The upward check valve a14 prevents the water in the viewing tank a2 from flowing back to the bottom cylinder a1 and causing the bottom cylinder a1 to overflow after a power outage or the pump stops.
