Technical Field

[0001] The utility model relates to the field of drilling fluid production equipment, in particular to a heating device used for the production of base fluid loss reducer. Background Art

The existing heating method generally uses an electric heating tube to heat the liquid, and then uses the liquid to heat the raw materials of the fluid loss reducer. However, during the heating process, a part of the electric heating tube does not contact the liquid, resulting in energy waste. Therefore, it is particularly necessary to develop a heating equipment for the production of fluid loss reducers that can save energy. Summary of the invention

[0011] 1. The utility model uses a liquid supply mechanism to pour heating liquid into the heating sleeve according to the amount of raw materials for preparing the fluid loss reducer inside the tank body, so that the height of the heating liquid is higher than the height of the raw materials for preparing the fluid loss reducer inside the tank body, and then starts the electric heating unit submerged in the heating liquid.
