時間的損失等は無視できないものであつた。(Prior Art) As a pretreatment for electrodeposition, baking and drying in the painting process of automobile bodies, etc., the bodies are generally subjected to chromate treatment to form a coating. When this chemical conversion treatment is performed on an automobile production line, recently, a large-scale bathtub-type surface treatment tank capable of mass production is used. However, this type of treatment tank has a large volume and is open at the top, so if the heated treatment liquid is left unattended, for example, if the temperature is 50 degrees Celsius at the end of chemical conversion treatment, the business may be closed for two days. It is normal for the temperature to drop by about 5 degrees Celsius, and during the winter, the temperature could drop to about 25 degrees Celsius after two days of closure. Therefore, when restarting operations, the processing liquid must first be heated to an appropriate temperature, and the amount of fuel consumed for heating and the time loss required for reheating until the start of processing cannot be ignored.

いる。 A chemical conversion treatment liquid is injected into the storage tank 2 and heated by a heating device (not shown) to raise the temperature to approximately 50°C. This chemical conversion liquid is circulated in the direction of arrow A shown in FIG. 1 under the pressure of the liquid ejected from the nozzle 3b by the circulation pump of the ejecting means 3.

After immersion, the chemical reaction is promoted and a film is formed over the entire surface of the body 8. Thereafter, the body 8 is lifted out of the chemical conversion treatment liquid and sent to the outlet side 2b. After being washed by a washing fountain 7 installed on the outlet side 2b, it is conveyed by a conveyor 9 to the next coating means.

止中の保温が維持される。 Next, if the chemical conversion work is suspended for a long time,
The heat insulating sheet 4 wound up on the reel 5b of the reel means 5 is unwound, and its end portion floats on the surface of the chemical conversion treatment liquid. At this time, the heat insulating sheet 4 is moved to the left by the flow of the surface of the chemical conversion treatment liquid which is moving in the direction of the arrow A even after the chemical conversion treatment operation, and is moved in the left direction by a tensile force. Then, this tip portion is locked to the side wall 1a on the inlet side 2a. As a result, the entire liquid surface of the chemical conversion treatment liquid is covered with the heat insulation sheet 4, heat dissipation of the chemical conversion treatment liquid is suppressed, and heat retention is maintained during the suspension of the chemical conversion treatment operation.

The leading end of the heat insulating sheet 4 that has been locked to the reel 5 is removed, and the motorized reduction gear 6a is driven to wind up the heat insulating sheet 4 onto the reel 5b. At this time, since the temperature of the chemical conversion treatment liquid is suppressed from decreasing by the heat insulating sheet 4, the temperature of the chemical conversion treatment liquid is increased to a predetermined temperature by heating for a short time, so that the chemical conversion treatment of the object to be treated 8 can be started at an early stage.

果も得られた。 By the way, according to the thermal insulation sheet of this example using a vinyl sheet, the liquid temperature of the chemical conversion treatment liquid decreases by 2 to 3 degrees Celsius on average when the business is closed for one day, and about 5 degrees Celsius when the business is closed for two days.
remained within the range. When this heat retention effect was converted into energy, it was found to be 1 million Kcal/5℃, which is equivalent to 1500Kg with 3Kg/cm 2 of steam, making it possible to save a lot of energy. In addition, in the past, it took about 5 hours to raise the temperature of the chemical conversion treatment liquid, which had dropped to about 25°C to about 50°C during a two-day break during the winter, but the temperature can be raised by only about 5°C. The result was that the time was shortened to approximately 1 hour.

By covering it with a heat-insulating sheet, the surface treatment liquid is kept warm while processing operations are suspended, so there is no need for a drive to unwind the heat-insulating sheet, and the structure of the heat-insulating sheet itself is simple, reducing equipment costs. It is inexpensive and extremely easy to maintain.
