Description

Siphon device

Technical Field

The present invention relates to a device for discharging liquid such as water, which is a device for discharging water by using a siphon principle, particularly to a siphon device which can control siphon time and does not overflow before siphon is started.

Background

At present, a large amount of water is drained by using a siphon device in many industries, particularly, the application of the aquaculture industry is more, a container of the known siphon device is communicated with an n-shaped siphon through a pipeline, the upper end of the n-shaped siphon is connected with a siphon damage pipe for controlling the siphon depth, and a water replenishing pipe is arranged in the container for replenishing water; when the water level in the container reaches the siphon starting water level, air in the n-shaped pipe is discharged, the siphon is started, and when the water level in the container descends and reaches the siphon stopping water level, the air inlet of the siphon breaking pipe is exposed out of the water surface, the air enters the siphon device, and the siphon is stopped. Such siphon devices have the following problems: when the water level in the container rises to the overflow water level, the water in the container begins to overflow outwards, which undoubtedly reduces the rising speed of the water level and hinders the start of siphon; only if the speed of supplementing water into the container is greater than the overflow speed, the water level in the container can rise, and once the water level in the container is higher than the siphon starting water level, the siphon can be started, and the siphon starting time is not controlled.

Disclosure of Invention

In order to overcome the overflow phenomenon that current siphon drainage device exists and the uncontrolled problem in siphon opportunity, the utility model provides a siphon device, this siphon device not only can prevent the overflow, can control the siphon moreover.

The utility model provides a technical scheme that its technical problem adopted is: the container of the siphon device is communicated with an n-shaped siphon pipe, the upper end of the n-shaped siphon pipe is combined with an air pipe, and a water supplementing device supplements water to the container, and the siphon device is characterized in that an n-shaped siphon descending pipe is also connected with an air blocking pipe, a discharge pipe and the like in series through pipe fittings and is in an M-shaped layout; the air pipe is communicated with an air control device. When the water level in the container rises and reaches the overflow water level, the overflow is started, the overflowed water is gradually accumulated at the bottom of the n-shaped siphon descending pipe, and when the pipe cavity at the bottom of the n-shaped siphon descending pipe is fully accumulated, the air at the upper part of the n-shaped siphon descending pipe is sealed to form an air plug to block the continuous outflow of the water and form an air resistance effect, at the moment, the liquid level in the container continuously rises, and after the liquid level exceeds the siphon starting water level, the liquid cannot flow out due to the existence of the air resistance effect; only when the exhaust valve of the pneumatic control device is opened, the gas sealed in the siphon tube is discharged, and the exhaust valve is closed, the siphon can be started, so that the effects of preventing overflow and controlling siphon opportunity are achieved.

The air control device of the siphon device comprises an exhaust valve and a destruction pipe which are respectively communicated with the air pipe through pipe fittings; when the liquid level in the container is higher than the siphon starting liquid level, the exhaust valve is opened, the air plug is discharged, the exhaust valve is closed, the siphon is started, the liquid level drops to the siphon stopping water level, the damaged pipe orifice is exposed out of the water level, air enters, the siphon is damaged, and water in the n-shaped siphon descending pipe is continuously siphoned out and filled with air; and (4) raising the water level, breaking the pipe orifice to be sealed by water, and entering the next cycle.

The air control device of the siphon device comprises an exhaust valve and an air inlet valve which are respectively communicated with the air pipe through pipe fittings, and the air inlet valve is communicated with a compressed air source; when the liquid level of the container is higher than the siphon starting liquid level, the exhaust valve is opened, the air plug in the siphon pipe is exhausted, the exhaust valve is closed, and the siphon is started; the air inlet valve is opened, the compressed air is filled into the n-shaped siphon pipe, an air plug is formed at the upper part of the n-shaped siphon pipe, the water flow is blocked, and the siphon is stopped.

When the siphon device is used, the exhaust valve and the air inlet valve can be electromagnetic valves, so that automatic control is facilitated.

In the siphon device, the outlet of the container can be opened at a certain position at the lower part of the container, namely, a lower water outlet type.

In the siphon device, the water outlet pipe of the container can be led out from the upper opening of the container through a group of n-shaped communicating pipes and then is connected with the n-shaped siphon pipes in series, namely, the upper water outlet type, and the communicating pipes are filled with liquid without air.

The beneficial effects of the utility model are that, can prevent the overflow, do benefit to the interior liquid level of container and rise rapidly, reach siphon start water level sooner to can conveniently control siphon, simple structure.
