Description
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.
The present invention relates to a flow meter that is installed on a pipeline of a water supply and drainage system and outputs measurement data of the amount of water flowing into the water supply and drainage piping system; A chlorine aqueous solution input unit for inputting a chlorine aqueous solution into the pipeline of the water supply and drainage system; And a control unit which is electrically connected to the flow meter and the chlorine aqueous solution input unit and decodes a signal output from the flow meter to calculate a flow rate value, and an input amount of the chlorine aqueous solution is set in advance according to the flow rate value, A control unit for controlling the chlorine aqueous solution input unit so that the chlorine aqueous solution is supplied into the water supply and drainage pipe at an input amount of the aqueous chlorine solution; And a display unit electrically connected to the control unit and displaying a flow rate value calculated by the control unit and an input amount of the aqueous chlorine solution according to the calculated flow rate value, .

The pressure correcting means may be formed of an inflatable member formed with an inlet portion through which the fluid enters and exits on one side thereof, and is formed of an elastic material and is flexible and variable in volume when the pressure of the fluid stored therein changes.
The inlet portion is provided with a first valve for opening and closing the inlet portion and a fluid supply port for supplying the fluid to the balloon member. The fluid supply port is provided with a second check valve for preventing the backflow of the fluid .
As an example, the fluid may be an inert gas.
