Embodiment 1

[0021] According to the order requirements of rosin, produce rosin.

[0022] A method of producing ground rosin comprising the use of steam boilers, steam superheaters, dissolving pots with agitators,

[0023] Centrifugal separator, fat-pressing pot, cooler, distillation pot, oil-water separator, steel screen mesh steaming slag pot at the bottom, oil storage tank processing equipment, the production method of described ground rosin comprises the following steps:

[0024] (1). Crushing: Ground pine resin is broken to a diameter of 150-200mm and naturally air-dried;

[0025] (2). Equipment cleaning: cleaning the dissolving pot;

[0026] (3). Add dissolving agent: add turpentine into the dissolving pot, and preheat the steam to 80 degrees Celsius;

[0027] (4). Moisture removal: When the turpentine in the steam heating and dissolving pot reaches 80°C, the water generated by the steam preheating will settle to the bottom of the dissolving pot, and the water at the bottom of the ...

Abstract

A method for producing ground rosin comprises the use of a steam boiler, a steam superheater, a dissolving pot with a stirrer, a centrifugal separator, a grease pressing pot, a distillation pot, a cooler, an oil-water separator, a slag evaporating pot with steel plate mesh at the bottom thereof, oil storage tanks and processing equipment. The process disclosed by the invention is very low in energy consumption, raw material residue can meet the heat source required for the production, coal or firewood are not used, no sulfur dioxide and sewage emissions occur in the combustion process. The recovery of rosin can reach 98%, the indicators, other than the color, of produced rosin, can meet the Grade 1 of National Standard.

Description

technical field [0001] The invention relates to a technique for obtaining rosin and turpentine by dissolving and separating ground rosin, in particular to a production method of ground rosin. Background technique [0002] The pine tree suffers from pest damage and other trauma, and the wound will flow out a lot of rosin, which accumulates over time and gathers at the roots of the pine tree. This kind of rosin is usually called ground pine resin. The rosin is a mixture of rosin and turpentine, and it is colorless when it flows out from the tree. Transparent viscous liquid. At present, it is obtained by artificially collecting turpentine, and then processed into rosin and turpentine, which become important chemical raw materials. There are two kinds of processing methods for artificially collected rosin: steam method and drip method. The steam method uses the water vapor produced by the steam boiler as the heat source. First, the pine resin is heated and dissolved, and the ...
