Description

Rosin size dissolving kettle Technical Field The utility model relates to the technical field of papermaking auxiliary agent processing, in particular to a rosin size dissolving kettle. Background Rosin size is a common sizing auxiliary agent for papermaking, and is prepared by adopting an alkali dissolution method, dissolving the rosin size by adding an alkaline solution such as sodium hydroxide, potassium hydroxide and the like, diluting the rosin size into emulsion, and using a dissolving kettle when dissolving. When rosin size is prepared, the solution is heated, the solution and the rosin size are stirred continuously, a heating rod or a heating wire arranged in a shell is generally used when a currently used dissolution kettle is heated, the heating range is very limited in order not to influence the stirring structure, and the solution in the middle of the dissolution kettle is difficult to heat, so that the dissolution effect is influenced. Disclosure of Invention The utility model provides a rosin gum dissolving kettle which can uniformly heat a solution so as to improve the dissolving effect.
