Negative-pressure siphon system

Abstract

The invention provides a negative-pressure siphon system, and relates to the technical field of siphon drainage. The negative-pressure siphon system comprises a first siphon pipeline, a second siphon pipeline and a ventilation pipe. The first siphon pipeline is communicated with the second siphon pipeline via the ventilation pipe, one end of the first siphon pipeline is arranged in a fish tank, the other end of the first siphon pipeline is arranged above a filter tank, the end, which is arranged in the fish tank, of the first siphon pipeline is a first water suction opening, the end, which is arranged above the filter tank, of the first siphon pipeline is a first drain outlet, one end of the second siphon pipeline is arranged in the fish tank, the other end of the second siphon pipeline is arranged above the filter tank, the end, which is arranged in the fish tank, of the second siphon pipeline is a second water suction opening, the end, which is arranged above the filter tank, of the second siphon pipeline is a second drain outlet, the first water suction opening is close to the bottom of the fish tank relative to the second water suction opening, and the second water suction opening is close to the top of the fish tank relative to the first water suction opening. The negative-pressure siphon system has the advantages that the negative-pressure siphon system is compact in structure and high in drain efficiency, and the water level is easy to adjust and can be automatically maintained to be within set height ranges.

Description

technical field [0001] The invention relates to the technical field of siphon drainage systems, in particular to a negative pressure siphon system. Background technique [0002] At present, there are many kinds of fish tank siphon drainage systems on the market. When the system is running, the sewage in the fish tank will enter the filter tank through a specially designed siphon pipeline to complete the filtration, and then the filtered water will be transported to the fish tank through the water pump to complete the fish tank and water tank. The water circulation between the filter tanks can automatically stop the drainage when the power is off, and it can automatically resume the drainage when the power is turned on. [0003] This kind of siphon drainage system generally realizes starting and stopping siphon through the ventilation pipe arranged in the fish tank, so the mouth of the ventilation pipe will always touch the water surface or be immersed in the water in the fis...

Problems solved by technology

[0003] This kind of siphon drainage system generally realizes starting and stopping siphon through the ventilation pipe arranged in the fish tank, so the mouth of the ventilation pipe will always touch the water surface or be immersed in the water in the fish tank, once the aquatic plants and fish floating in the fish tank If food, large foreign matter or fish corpses block the nozzle, the siphon cannot be interrupted when the power is off. If it is not found in time, the water in the fish tank will be drained, causing unnecessary losses.

At the same time, since the existing siphon drainage system uses a single drainage pipeline, its drainage is limited

If you want to increase the displacement, you need to increase the diameter of the pipe, or add a group of identical siphon pipes, and adding a group of identical siphon pipes means that a siphon pipe and a vent pipe will be added in the fish tank, which will not only increase the cost High, it will increase the installation space, and there is another safety hazard
