Description

[0001] Discharge flow control system using siphonage [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge amount adjustment system using a siphon phenomenon, and more particularly, to a discharge amount adjustment system using a siphon phenomenon capable of adjusting a discharge amount more efficiently than before.

Sewage, including agricultural sewage, industrial sewage, domestic sewage, etc., is appropriately treated through various routes and then directed to rivers.

It is common to use a system capable of controlling the discharge amount because various types of problems may occur in the facilities related to the water treatment when the sewage is discharged without any treatment and without controlling the discharge amount of the sewage.

Currently, the discharge rate control system is largely divided into a system using an underground treatment tank and a system using a natural downfall treatment tank.

However, in the case of the discharge amount control system using the electronically groundwater treatment tank, since the treatment water tank must be buried in the ground, not only a large site but also a civil engineering cost due to a large scale civil engineering work is generated.

In addition, in the case of a discharge control system using an underground treatment water tank, a discharge pump must be used. In such a case, there is a problem in that a cost and a power ratio are incurred in using a discharge pump.

In the latter case, an overflow problem is likely to occur in the case of a discharge volume control system using a submerged water treatment tank. However, when the discharge amount is small or the flow rate is low, there is a problem that the foreign matter in the piping is accumulated.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a view for explaining a siphon phenomenon, and FIG. 3 is a schematic view of a system for controlling the amount of discharged air using the siphon phenomenon of FIG. 1 according to the first embodiment of the present invention. Fig.

Referring to these drawings, the discharge amount control system using the siphon phenomenon according to the present embodiment is capable of controlling the discharge amount in a more efficient manner than before, and includes a water tank 110, a discharge water pipe 120, 130, an effluent control valve 150, and a controller 160.

The water tank 110 is a tubular structure used as a treated water tank for discharged water. And the discharged water flows in from one side of the upper part of the water tank 110.

When the water tank 110 is used as in the present embodiment, since a large-scale civil engineering work is not required, it is possible to solve the problem that the construction work cost due to a large-scale civil engineering work is incurred.

The water tank 110 is filled with discharged water, and a water level sensing unit 115 is provided to sense the water level of the discharged water.

In other words, the water level sensing unit 115 is provided in the water tank 110 to sense the water level of the water discharged in the water tank 110.

In this embodiment, since the discharge amount is adjusted by using the siphon phenomenon, the water level in the water tank 110 is controlled to be about 30% to 80%. That is, the water level of the discharged water is controlled not to be lower than 30% and not higher than 80%.

Of course, it may be ideal to manage with these numbers, but the scope of rights of the invention can not be limited to these figures.

For reference, the siphon phenomenon refers to the principle that when liquid or other liquid goes up above a certain height, the liquid falls down to gravity. At that time, the liquid moves up and down again due to the pulling force.

At this time, the lower part should be lower than the connected part so that the water can go down. This phenomenon is that when the water of the toilet is lowered, the water is more initially, then descending all the way down to the floor, .

In other words, the principle of the siphon phenomenon is to remove the air inside the straw by the force of water dropping instead of the air in the straw.

Will be described with reference to FIG. Fig. 2 shows the structure of the male and female couples which does not overflow even when water is poured.

2, when the water does not reach the uppermost part of the hose, the height of the water surface is the same because the atmospheric pressure outside the hose is equal to the atmospheric pressure in the hose. At this time, the water does not come up to the end of the hose, so the water does not come out through the straw.

Referring to the right side of FIG. 2, when the water is filled to the end of the hose, the water exits the hose. At this time, the water that goes out through the straw serves as the sink of the straw with the mouth.

If the water in the straw is drained down but the water does not follow it, the pressure in the straw is lowered. Therefore, the pressure in the straw is smaller than the water pressure pushing it from the inside of the bowl into the straw, so that the water comes into the straw.

That is, once the water begins to fall out, the water that is exiting serves to suck the straw so as to pull water backward. Such a phenomenon is referred to as a siphon phenomenon. In this embodiment, It is.

One end of the discharge pipe 120 is disposed at a predetermined position inside the water tank 110 and the other end is disposed outside the water tank 110 to form a siphon phenomenon. .

Particularly, in this embodiment, since the discharged water discharged through the discharge water pipe 120 is discharged automatically by the siphon phenomenon, it is not necessary to use the discharge pump as usual. Therefore, the power ratio and the maintenance cost due to the non-use of the discharge pump can be reduced.

A flow meter 125 is installed in the discharge water pipe 120. And the flow rate discharged per unit time by the flow meter 125 can be sensed and utilized as data for water quality management.

The atmospheric pressure removing dummy pipe 130 is disposed in the water tank 110 along the vertical direction of the water tank 110 so as not to generate atmospheric pressure due to air inflow into the discharge water pipe 120, And the other end 130a is a pipe disposed in the bottom area of the water tank 110. [

The atmospheric pressure removing dummy pipe 130 may be connected to the discharge water pipe 120 by a pipe connection port 140.

The other end 130a of the atmospheric pressure removing dummy pipe 130 may be disposed in the interval between the bottom (0%) and 30% of the water tank 110 in this embodiment. This is because the water level in the water tank 110 is controlled to be about 30% to 80% as described above.

The discharge water control valve 150 is coupled to the discharge water pipe 120 and selectively controls the flow of the discharge water in the discharge water pipe 120.

Although the discharged water control valve 150 may be applied as a mechanical valve, the discharged water control valve 150 may be applied as a three-way solenoid valve or the like which can be automatically controlled by the controller 160 in the present embodiment.

On the other hand, the controller 160 controls the operation of the discharge water control valve 150 based on information from the water level sensing unit 115 so as to secure the amount of discharge water required for maintenance and reuse of the siphon phenomenon in the water tank 110 As shown in FIG.

Specifically, in the present embodiment, when the amount of the discharged water required for maintenance and reuse of the siphon phenomenon in the water tank 110 is lower than the minimum reference amount, the controller 160 controls the other end of the atmospheric pressure removing dummy pipe 130 to discharge water So that the discharge water control valve 150 is closed and the flow of the discharge water in the discharge water pipe 120 is turned off.

When the amount of the water in the water tank 110 is lower than 30%, the controller 160 closes the discharge water control valve 150 and discharges the discharge water from the discharge water pipe (not shown) 120 so that the discharged water in the water tank 110 is not discharged any more.

In this embodiment, the controller 160 controls the discharge water control valve 150 so that the discharged water does not overflow when the amount of discharged water required for maintenance and reuse of the siphon phenomenon in the water tank 110 is higher than the maximum reference amount, And controls the flow of the discharged water in the discharged water pipe 120 to be turned on.

When the amount of the discharged water in the water tank 110 is higher than 80%, the controller 160 opens the discharge water control valve 150 to open the discharge water pipe (not shown) 120 so that the discharged water in the water tank 110 does not overflow but is discharged well by the siphon phenomenon through the discharge water pipe 120. [

The controller 160 that performs such a role may include a central processing unit 161, a memory 162, and a support circuit 163, as shown in FIG.

The central processing unit 161 controls the flow rate of the siphon phenomenon in the water tank 110 based on the information from the water level sensing unit 115 so as to secure the amount of water required for maintenance and reuse in the water tank 110 150 may be one of a variety of computer processors that are industrially applicable.

The memory 162 (MEMORY) is connected to the central processing unit 161. [ The memory 162 may be a computer-readable recording medium and may be located locally or remotely and may be any of various types of storage devices, including, for example, a random access memory (RAM), a ROM, a floppy disk, At least one or more memories.

A support circuit 163 (SUPPORT CIRCUIT) is coupled with the central processing unit 161 to support the typical operation of the processor. Such a support circuit 163 may include a cache, a power supply, a clock circuit, an input / output circuit, a subsystem, and the like.

The controller 160 controls the discharge water control valve 150 based on the information from the water level sensing unit 115 so as to secure the amount of discharged water required for maintenance and reuse of the siphon phenomenon in the water tank 110. [ And the like. At this time, the controller 160 controls the operation of the discharge water control valve 150 based on the information from the water level sensing unit 115 so as to secure the amount of discharge water required for maintenance and reuse of the siphon phenomenon in the water tank 110 And the like may be stored in the memory 162. [0033] FIG. Typically, a software routine may be stored in the memory 162. The software routines may also be stored or executed by other central processing units (not shown).

Although processes according to the present invention are described as being performed by software routines, it is also possible that at least some of the processes of the present invention may be performed by hardware. As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.
