Rosin dissolving kettle comprehensive heating structure

Abstract

The invention discloses a rosin dissolving kettle comprehensive heating structure which comprises a support device, a base arranged at the lower end of the support device, and a dissolving kettle bodyarranged above the base, wherein the dissolving kettle body comprises a heating shell, a kettle liner arranged on the inner wall of the heating shell, a cover body arranged above the heating shell, and a stirring motor arranged at the upper middle part of the cover body and fixed to the cover body; the heating shell comprises a ceramic shell in contact with the kettle liner, an aluminum plate arranged on the outer surface of the ceramic shell and fixed to the ceramic shell, and an asbestos plate arranged on the outer side of the aluminum plate, fixed to the aluminum plate and used for thermalinsulation. After an aluminum plate electric heating tray of the rosin dissolving kettle heats, the ceramic shell transfers heat to the kettle liner for heating so as to melt rosin stored in the kettle liner; moreover, through the thermal insulation of the aluminum plate and the heat locking of the asbestos plate, the heat loss is prevented, and the rosin in the kettle liner is kept in a molten state; therefore, the structure has the advantages of good heating effect, good thermal insulation effect, environmental protection and energy conservation.

Description

technical field [0001] The invention relates to an overall heating structure of a rosin dissolving kettle. Background technique [0002] Rosin refers to a non-volatile natural resin obtained from pine rosin through different processing methods. Rosin is an important chemical raw material, widely used in soap, paper, paint, rubber and other industries. Kettle, originally intended to be a container, is actually what we call a pot now. A dissolving kettle should be a container that looks like a pot for dissolving a certain substance. The still commonly used still is called autoclave now, is a kind of facility of sealing pressure. [0003] The preparation method of cationic dispersed rosin gum generally adopts high-molecular cationic polymer emulsified rosin, which has poor compatibility with rosin, and needs to emulsify rosin under strong acidic conditions to reduce the ionization of carboxyl groups in rosin, and it is difficult to form stable rosin emulsion; or The emulsif...

Problems solved by technology

[0003] The preparation method of cationic dispersed rosin gum generally adopts high-molecular cationic polymer emulsified rosin, which has poor compatibility with rosin, and needs to emulsify rosin under strong acidic conditions to reduce the ionization of carboxyl groups in rosin, and it is difficult to form stable rosin emulsion; or The emulsification system needs to be subjected to high-pressure homogeneous treatment, and the equipment investment is high; the technology of partially saponifying rosin by alkali treatment reduces the free rosin content of rosin sizing agent, which is not conducive to improving the sizing efficiency of rosin. Therefore, in combination with the above problems And for the purpose of improving the compatibility of rosin, a rosin dissolving kettle was designed

[0004] However, the rosin dissolving kettles currently on the market are not only complex in structure, but also have single functions. They are not equipped with temperature sensing devices, cannot detect the temperature in the rosin dissolving kettle, and cannot maintain a constant temperature in the rosin dissolving kettle, resulting in uneven quality of the produced rosin; There is no comprehensive heating setting for the kettle body, resulting in only heating the bottom of the kettle body and only melting a small amount of rosin, so there is a problem of poor heating effect; moreover, because the existing rosin dissolving kettle is turned off after heating and melting Due to the lack of heat preservation equipment, the heat dissipation speed is fast and there is no good heat preservation effect. Therefore, the rosin is gradually cooled down, which is not conducive to industrial production and a serious waste of resources.
