Description

AN AUTOMATIC RECHLORINATION APPARATUS [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic recrystallization apparatus, and more particularly, to an automatic recrystallization apparatus capable of accurately maintaining chlorine concentration in a sewerage system.

Chlorine, which is strong in disinfecting power and easy to obtain and cheap in price, is widely used to sterilize various bacteria and Escherichia coli existing in water and sewage.

In the past, solid type chlorine was used in many cases, but solid type chlorine had difficulty in controlling the amount because it was difficult to finely adjust the amount of the supplied chlorine.

Therefore, in recent years, a liquid aqueous solution of chlorine has been widely used.

A general input device for introducing a chlorine aqueous solution into the water supply and sewerage system includes a storage tank for storing a chlorine aqueous solution, a metering pump for discharging a chlorine aqueous solution stored in a storage tank in a fixed amount, a pipe connecting the storage tank and the metering pump, .

However, since the storage tank of the general chlorine aqueous solution input device is not hermetically closed, the external air is introduced into the storage tank every time the chlorine aqueous solution is discharged and the amount thereof is reduced. The chlorine aqueous solution is deteriorated by prolonged contact with the introduced external air and the chlorine concentration in the aqueous solution changes.

Therefore, even when a quantitative amount of chlorine aqueous solution is introduced into the water supply and drainage system by the metering pump, the amount of chlorine necessary for sterilization is less than a predetermined amount, and effective sterilization and disinfection can not be performed.

Accordingly, the storage tank in which the chlorine aqueous solution is stored may be configured to be hermetically sealed so as to prevent the inflow of outside air. However, when the storage tank is sealed, vacuum pressure is generated in the inner space due to continuous discharge of the chlorine aqueous solution. The vacuum pressure interferes with the discharge of the aqueous solution of chlorine, and with the overload of the metering pump, it becomes difficult to discharge the aqueous solution of the chlorine in a fixed amount.

On the other hand, the amount of chlorine input should be adjusted according to the flow rate in the water supply and sewage pipe. However, since it is not possible to control the concentration of the chemical input according to the prior art, the disinfection effect is reduced due to the lack of chlorine concentration when the water supply amount is increased, and excessive chlorine concentration occurs when the water supply amount is decreased.

In order to solve such a conventional problem, the inventor of the present invention has introduced the following structure, and it is possible to input the correct chlorine aqueous solution according to the flow rate of the water supply and drain pipe and to know the timing of addition of the chlorine aqueous solution easily, The chlorine aqueous solution can be stored in a sealed storage tank without deterioration for a long time and the inside of the sealed storage tank is maintained at a constant pressure so that a constant amount of chlorine aqueous solution can always be discharged by a metering pump without error, And to develop an automatic recrystallization apparatus capable of accurately maintaining the chlorine concentration.

1 is a block diagram conceptually showing a configuration of an automatic recrystallization apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the automatic recolor dispensing apparatus according to an embodiment of the present invention includes a flow meter 2000, a chlorine aqueous solution input unit 1000, a control unit 3000, a display unit 4000, 5000), and a notification unit 6000.

The flow meter 2000 is installed on the pipeline of the water supply and drainage system and outputs measurement data of the amount of water flowing into the water supply and drainage pipe. As an example, the flow meter 2000 may be a mechanical or electronic sensor.

The chlorine aqueous solution input unit 1000 introduces an aqueous chlorine solution into the pipeline of the water supply and drainage system. The chlorine aqueous solution injecting unit 1000 injects the aqueous chlorine solution into the water supply and drainage pipe through the control unit 3000.

FIG. 2 is a perspective view showing an embodiment of the chlorine aqueous solution input part shown in FIG. 1, and FIG. 3 is a perspective view showing an embodiment of the pressure correction means shown in FIG.

2 and 3, the chlorine aqueous solution input unit 1000 includes a sealed storage tank 100 storing a chlorine aqueous solution, a metering pump 200 discharging a chlorine aqueous solution of the storage tank 100 by a predetermined amount, And a pressure correction means 300 for supplying the fluid to the storage tank 100 when the chlorine aqueous solution is discharged.

As the pressure correcting means 300, a balloon member 310 formed of a stretchable material and a storage container 320 made of a synthetic resin material having a bellows-shaped side surface may be used.

The storage tank 100 has a storage space 110 in which a chlorine aqueous solution is stored. An inlet 120 for supplying the aqueous chlorine solution to the storage space 110 and an outlet 130 for discharging the aqueous chlorine solution are formed on the outer surface of the storage tank 100.

A circular pipe is fixed to the inlet port 120 and the outlet port 130 so as to protrude from the outer surface of the storage tank 100. The inlet 120 is located above the storage tank 100 and the outlet 130 is located below the storage tank 100.

The inlet port 120 is opened and closed by a stopper 121 and a packing is provided inside the stopper 121 to prevent external air from flowing into the internal storage space 110 of the storage tank 100, (Not shown).

The dosing pump 200 is provided at the discharge port 130. In addition, the discharge port 130 is provided with a first check valve 400. The first check valve 400 prevents backflow of the outside air and the aqueous chlorine solution when a pressure drop occurs in the interior of the storage tank 100 due to the discharge of the aqueous chlorine solution.

The balloon member 310 formed of a rubber elastic material is used as the pressure correction means 300. When the fluid is supplied through the inlet 311, the rubber material forming the outer wall of the balloon member 310 is stretched and bulged as the balloon member 310 is stretched .

Further, when the supplied fluid is discharged through the inlet 311 and the internal pressure is lowered, the outer wall of the rubber material shrinks and the volume becomes smaller. In this way, the volume of the balloon member 310 varies according to the change of the internal pressure, so that the interior always maintains a constant pressure.

When the balloon member 310 is connected to the storage tank 100 and the internal pressure of the storage tank 100 is lowered due to the discharge of the aqueous chlorine solution, the volume of the balloon member 310 is reduced, So that the internal pressure drop of the storage tank 100 is automatically corrected.

Meanwhile, a protection box 500 for protecting the balloon member 310 is provided at one side of the storage tank 100. A fluid guide pipe 600 is provided to connect the balloon member 310 stored in the protective box 500 to the storage tank 100.

The protective box 500 is formed to a sufficient size such that the balloon member 310 can be embedded even if it is expanded to an appropriate size. The opening and closing door 510 is formed on one side and the opening 520 is formed in the opening and closing door 510 to allow the user to visually confirm the inside of the opening and closing door 510.

One end of the fluid guide pipe 600 is connected to the upper part of the storage tank 100 and the other end is connected to the inlet part 311 of the balloon member 310.

The balloon member 310 and the fluid guide pipe 600 are subjected to a threaded joint method using a nipple, a socket, and a union in a pipe joint method.

Accordingly, the inlet 311 of the balloon member 310 is fixed by a pipe for pipe connection.

The inlet 311 of the balloon member 310 is provided with a fluid supply port 610 for supplying fluid to the balloon member 310. The fluid supply port 610 is provided with a second check valve 700. The second check valve 700 prevents the back flow of the fluid when the fluid is supplied.

The inlet 311 is provided with a first valve 620 for shielding the inlet 311 when fluid is supplied through the fluid inlet 610.

Meanwhile, the fluid guide pipe 600 is provided with a second valve 630 for opening and closing the internal pipe of the fluid guide pipe 600. The second valve 630 shields the channel of the fluid guide pipe 600 when the balloon member 310 is replaced or repaired, thereby preventing external air from entering the storage tank 100.

In this way, since the balloon member is connected to the fluid guide pipe by being connected to the pipe, the balloon member filled with the inert gas can be easily carried and replaced.

The fluid to be stored in the balloon member 310 is an inert gas that is chemically very stable and does not react well with other common materials. Examples of the inert gas include helium, argon, nitrogen, and the like.

4, the distance between the balloon member 310 and the storage tank 100 may be minimized by locating the protection box 500 on the upper surface of the storage tank 100. Referring to FIG.

5 and 6 show a storage container made of a synthetic resin material having a bellows shape in side view, which is another embodiment of the pressure correcting means.

Since the side surface of the storage container 320 is wrinkled in a bellows shape, unlike the balloon member in which the outer wall of the rubber material is shrunk or stretched, the folds of the side surface are folded and expanded.

The control unit 3000 is electrically connected to the flow meter 2000 and the chlorine aqueous solution input unit 1000. The control unit 3000 decodes a signal output from the flow meter 2000 to calculate a flow rate value, and an input amount of the chlorine aqueous solution according to the flow rate value is set in advance. The chlorine aqueous solution input amount, which is previously set according to the flow rate value, The chlorine aqueous solution input unit 1000 is controlled so that the aqueous solution is supplied into the water supply and drainage pipe.

The display unit 4000 is electrically connected to the control unit 3000 and displays a flow rate value calculated by the control unit 3000 and an input amount of the aqueous chlorine solution according to the calculated flow rate value. For example, the display unit 4000 may display the input amount of the aqueous chlorine solution according to the flow rate value as the chlorine concentration value. That is, the chlorine concentration value can be expressed in ppm.

Meanwhile, the automatic re-chlorine input device according to an embodiment of the present invention includes a drug amount detection sensor 5000 and a notification unit 6000.

The chemical quantity detection sensor 5000 is electrically connected to the control unit and is installed in the storage space of the chlorine aqueous solution input unit 1000 to measure the amount of aqueous chlorine solution. The chemical quantity detection sensor 5000 outputs a signal to the control unit when the amount of chlorine aqueous solution in the storage space 110 of the chlorine aqueous solution input unit 1000 is less than a predetermined amount.

The notification unit 6000 is electrically connected to the control unit 3000. When a signal is output from the drug amount detection sensor 5000 to the control unit 3000, the notification unit 6000 is controlled through the control unit 3000 to notify the time of drug introduction . In one example, the notification unit 6000 may be a buzzer or a lamp.

Here, the control unit 3000 is set to operate the notification unit 6000 when a signal is inputted from the medicine amount detection sensor 5000.

Hereinafter, an operation of the automatic recolorizing apparatus according to one embodiment of the present invention will be described.

First, the flow meter 2000 installed on the pipeline of the water supply and drainage pipe measures the amount of water flowing into the water supply and drainage pipe, and outputs measurement data to the control unit 3000.

The control unit 3000 decodes the measurement data input from the flow meter 2000 to calculate the flow rate value and controls the chlorine aqueous solution input unit 1000 so that the chlorine aqueous solution is supplied at a preset amount of chlorine aqueous solution corresponding to the flow rate value do. At this time, the display unit 4000 displays the flow rate value calculated by the control unit 3000.

The chlorine aqueous solution input unit 1000 operates under the control of the control unit 3000 to supply the aqueous chlorine solution. At this time, the operation of the chlorine aqueous solution input portion 1000 will be described in detail below.

A proper amount of chlorine aqueous solution is stored in the storage tank 100 through the inlet 120 of the storage tank 100. The inlet 120 is shielded by a cap 121. Further, the fluid guide tube 600 is also shielded by the second valve 630. Thus, the storage tank 100 is sealed.

Meanwhile, an inert gas is injected into the balloon member 310. At this time, the inlet 311 of the balloon member 310 is shielded by the first valve 620. Then, the inlet portion 311 of the balloon member 310 is connected to the fluid guide tube 600 located inside the protective box 500.

The first valve 620 of the inlet part 311 and the second valve 630 of the fluid guide pipe 600 are turned on to connect the storage tank 100 and the balloon member 310, (310).

Thus, the chlorine aqueous solution input unit 1000 is operated in a state where the storage tank 100 and the balloon member 310 are communicated with each other.

The control unit 3000 drives the metering pump 200 to discharge a predetermined amount of the chlorine aqueous solution from the storage tank 100. At this time, a pressure drop occurs in the storage space 110 of the sealed storage tank 100. The pressure drop in the storage space 110 hinders the normal operation of the metering pump 200 and makes it difficult to discharge a fixed amount of aqueous chlorine solution.

However, according to the present invention, the fluid stored in the balloon member 310, which is the pressure correction means 300, is supplied into the storage tank 100 where the pressure drop occurs due to the discharge of the aqueous chlorine solution. At this time, the balloon member 310 is self-contracted to reduce the volume, thereby keeping the internal pressure constant with the communicating storage space 110.

Accordingly, the storage space 110 of the storage tank 100 always maintains a constant pressure. Then, the metering pump 200 is allowed to operate normally.

The input amount of the aqueous chlorine solution according to the calculated flow rate value is displayed on the display unit 4000 in this process.

On the other hand, the chemical quantity sensor 5000 detects the amount of aqueous chlorine solution in the storage space 110 after the chlorine aqueous solution is supplied normally and through the process. For example, when the amount of chlorine aqueous solution in the storage space 110 is lowered to a certain level or lower, the chemical quantity sensor 5000 may output a signal to the control unit 3000.

When a signal is output from the medicine quantity detection sensor 5000, the control unit 3000 activates the notification unit 6000. For example, when the notification unit 6000 is configured as a buzzer, the buzzer may operate to output a notification sound.

When an alert sound is output, the administrator further supplies an aqueous chlorine solution into the storage space 110.

By using the automatic recrystallization apparatus according to one embodiment of the present invention, it is possible to input an accurate chlorine aqueous solution according to the flow rate of the water supply and drainage pipe, easily know the timing of addition of the chlorine aqueous solution, The aqueous solution can be stored in the sealed storage tank 100 without deterioration for a long time and the inside of the sealed storage tank 100 is maintained at a constant pressure so that the constant amount pump 200 always discharges a predetermined amount of the chlorine aqueous solution I can do it. As a result, the chlorine concentration in the water supply and sewerage can be accurately maintained.

7 shows another embodiment of the chlorine aqueous solution input portion of the automatic recrystallization apparatus of the present invention.

Referring to FIG. 7, another embodiment of the present invention includes a retractable bag 800 that is made of a stretchable material and shrinks and expands in a storage space 110 of a storage tank 100. The stretchable pouch 800 is installed such that one side communicates with the outside of the storage tank 100.

In another embodiment of the chlorine aqueous solution input unit 1000, when a pressure drop occurs in the storage space 110 as the chlorine aqueous solution is discharged, external air flows into the expansion bag 800 and the expansion bag 800 is expanded.

When the stretchable pouch 800 is inflated, the volume of the gas other than the chlorine aqueous solution in the storage space 110 is kept constant. Therefore, the pressure drop in the storage space 110 is corrected.

The description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention.
