Release agent diluent manufacturing apparatus {DEVICE OF MANUFACTURING DIPPING SOLUTION}

The present invention relates to a release agent diluent preparation apparatus, and more particularly to a release agent diluent preparation apparatus for maintaining a constant concentration and temperature of the release agent diluent prepared in the stirring vessel.

Conventionally, to control the temperature of the release agent dilution agitator, the internal temperature of the release agent diluent is increased by spraying steam directly inside the agitator, or a heating cable is installed outside the agitator to control the temperature of the agitator. .

In case of controlling the temperature by spraying steam directly inside the stirring tank, when the stirring is started, water and a release agent stock solution of a quantity corresponding to the desired release agent diluent concentration (%) are added to the stirring / mixing, and is normally stored. When the temperature of the release agent diluent drops during medium or aging, additional steam is automatically introduced to adjust the set temperature to compensate for this. As a result, the release agent diluent at a concentration lower than the release agent diluent concentration (%) desired by the initial user is adjusted. This may cause a manufacturing problem.

Moreover, due to seasonal factors, the amount of steam required to adjust the release agent diluent to the set temperature will be different, and the concentration of the release agent diluent will also change each time.

The temperature is controlled using a heat supply and a temperature sensor.

However, Japanese Patent Application No. 2005-127608 also relates to keeping a temperature by putting an object contained in a separate container (bottle) in a liquid tank maintained at a constant temperature, and is mainly suitable for a compact apparatus.

Therefore, the conventional methods described above are large-capacity and the solution inside the stirring tank is repeatedly added to / discharged at different temperatures from time to time, it is difficult to control the temperature for a solution containing a solid non-liquid inside, it is difficult to separate There is a cost loss and a risk of using a heating device.

Hereinafter, the release agent diluent preparation process using the release agent diluent preparation apparatus according to an embodiment of the present invention will be described in more detail.

First, input the concentration (%) of the release agent diluent to be manufactured by the user on the control PC phase 82 of the controller 80, the set temperature (60 ± 10 ℃), the heat exchanger control temperature, that is, the hot water supply temperature, etc. do.

Then, when the release agent diluent production begins, the control PC 82 automatically calculates the amount of water required and the amount of the release agent stock solution, and preferentially obtains some hot water (eg, the set amount of hot water 1/3, set temperature + 5 ° C). Input. The weight of hot water introduced into the stirring tank 10 is sensed and controlled through a load cell 16 installed in the stirring tank 10.

After the addition of some amount of hot water, the release agent stock solution is also input by the amount input to the control PC 82, and at this time, the release agent diluent is the temperature of the release agent diluent setting the measured average value of the first temperature sensor 15 Compare with temperature in real time.

And, if the remaining hot water (for example, 2/3 of the set hot water amount) is the temperature of the release agent diluent is equal to the set user set temperature, the temperature of the water supplied from the heat exchanger is supplied equal to the user set temperature, the temperature of the release agent diluent is If the temperature is lower than the user's set temperature, the heat is supplied to the higher temperature from the heat exchanger 30, and if the temperature is higher than the user's set temperature, the temperature is lower.

The temperature of the hot water supplied is measured from the second temperature sensor 51, the temperature of the cold water introduced into the heat exchanger 30 is measured by the third temperature sensor 61, the heat exchanger ( By controlling the pressure and temperature of the steam supplied to the 30 in real time to control the temperature of the hot water supplied to the stirring tank (10).

Will be able to maintain.

In addition, in order to control the temperature of the hot water supplied from the heat exchanger 30 to the stirring tank, the temperature of the hot water required for temperature control of the release agent diluent in the stirring tank 1 and the temperature of the cold water (usually room temperature) supplied to the heat exchanger. The temperature of the steam introduced into the heat exchanger 30 is controlled in real time.

Here, the temperature of the hot water supplied to the stirring vessel 10 depends on the temperature of the release agent diluent in the stirring vessel. In other words, the larger the temperature difference between the required hot water temperature and the cold water supplied, the greater the temperature rise during the unit time. Therefore, the temperature of the hot water is controlled by increasing the temperature of the steam supplied to the heat exchanger and controlling the temperature to decrease as the temperature difference decreases. To control.

On the other hand, in order to control the temperature of a mold release agent dilution liquid, the difference between the preset temperature of a mold release agent dilution liquid and actual temperature is calculated, and the temperature of the warm water required is determined.

Therefore, if the actual release agent diluent temperature is higher than the temperature set by the user, the temperature of the hot water is lowered. If the temperature of the release agent diluent is lower than the user required temperature, the temperature of the hot water is controlled.

As such, the release agent diluent production apparatus 1 of the present embodiment can improve the quality of the release agent diluent prepared to maintain the release solution stirring / maturation temperature inside the large-capacity release solution stirring tank at a constant temperature desired by the user at all times.
