The method of attaching the temperature sensor protection tube to the lid has the following drawbacks because the temperature sensor protection tube becomes long. I. It cannot be used for melting solids or the like because the solids collide with the temperature sensor protection tube and bend and break. B. When the powder or the like is dissolved, the powder adheres to the temperature sensor protection tube, and the cleaning work efficiency becomes extremely poor. C. In other work, the temperature sensor protection tube is often bent and damaged. The method of attaching the temperature sensor protection tube to the body or bottom of the tank has the following drawbacks. I. In order to attach the temperature sensor protection tube to the body or bottom of the tank, it is necessary to weld a flange or socket for attaching the temperature sensor protection tube to the tank.
The processing cost is high. Especially, a veneer and a tank with a jacket are more expensive. B. In order to improve the heat exchange efficiency of the liquid in the tank, a method of scraping the inner surface of the tank is adopted, but since the temperature sensor protection tube is protruding inside the tank, it is not possible to scrape the entire inner surface of the tank. That is, one circumferential portion of the inner surface of the tank remains as a non-scratchable portion. Therefore, the efficiency of heat exchange deteriorates, and the product quality varies. C. Since the temperature sensor protection tube is protruding inside the tank, the cleaning work efficiency is poor. The present invention was invented in order to solve these drawbacks all at once.
