Description

Technical Field

[0001] The utility model relates to a heating device, in particular to a heating device for producing epoxy floor paint. Background Art

[0002] The raw materials of epoxy floor paint easily absorb moisture in the air during storage, resulting in a high water content. In order to meet process requirements, it is usually necessary to heat and dehydrate the raw materials with excessive water content. Currently, the commonly used heating and dehydration method is mostly to use a container with an electric heater installed at the bottom to directly heat the raw materials, which can easily lead to uneven heating of the raw materials.

[0003] After searching, the patent with announcement number CN108441021A discloses a production and processing technology of acrylic floor paint waterproof coating. The heating device disclosed in the process uses water bath heating to make the processing box enter the interior of the water bath box, providing an appropriate reaction temperature for the processing box, and the temperature provided is uniform and mild. When dehydrating, the dehydration mechanism with a special structure can be used to collect and discharge the dehydrated water, with high collection efficiency, energy saving, and simple and convenient operation; the processing box can be raised and lowered to facilitate the operation of loading and unloading materials and water bath.

[0004] When the above scheme is actually used, since the processing box storing the raw materials is at normal pressure during heating, the boiling point of the water content of the raw materials in the processing box is about 100°C. It takes a long time to heat the raw materials to make the water content reach the process standard, which needs to be improved. Utility Model Content
