Embodiment Construction

[0040] The present invention illustrates the rosin refining kettle of the present invention through the following examples. However, those skilled in the art understand that any improvement or change made to the present invention falls within the protection scope of the present invention.

[0041] The embodiment of this rosin refining kettle is described below in conjunction with the rosin refining flow process.

[0042] Put the metered liquid rosin into the refining kettle body 1 and the oval lower head 11 from the feed port 4, respectively open the oil inlet and outlet valves of the serpentine coil, the oil inlet and outlet valves of the mosquito coil coil, and the outer The oil inlet and outlet valves of the semi-circular coil allow the high-temperature heat transfer oil to enter the serpentine coil 10 and the mosquito coil respectively from the oil inlet 16 of the serpentine coil, the oil inlet 13 of the mosquito coil, and the oil inlet 12 of the outer semicircular coil. ...

Abstract

The invention provides a rosin refining kettle, which comprises a cylindrical pot body, an upper sealing head and a lower sealing head and is characterized by further comprising a mosquito-repellent incense coiler, and preferably comprising a snake-shaped coiler and an outer semicircular coiler. The invention also provides a refining method by using the rosin refining kettle. By the high-efficiency rosin refining kettle, a height-diameter ratio can be controlled effectively and a heating position can be flexibly adjusted according to change of a liquid level during rosin refining, and the load on a vacuum pump set is low. By the refining method, the grade of an obtained rosin product is much higher than the standard of a special grade in China.

Description

technical field [0001] The invention relates to a rosin refining kettle, in particular to a rosin refining kettle utilizing multi-tube heat exchange. The invention also provides a method for refining rosin by using the still for refining rosin. Background technique [0002] At present, there is a refining kettle for the production of rosin and turpentine, which is mainly composed of a material pot and a spiral steam pipe installed in the middle of the material pot. The device has the disadvantages of low thermal efficiency and slow temperature rise. [0003] And the existing jacket heating type elliptical refining still is also the refining still commonly used when rosin is refined, and this refining still has following shortcoming in rosin refining: [0004] One is jacket heating, which has a small heating area for rosin, and cannot effectively control the height-to-diameter ratio of the refining kettle, resulting in low refining efficiency, large residues in the refining...
