Embodiment 1

[0022] The composition and connection method of the rubber sinking tank (1) specially used for rubber seed oil derubberization of the present invention are as follows: the main body of the device is a closed tank body (1); the tank body (1) is provided with two The inlet and two outlets with valves are: rubber seed crude oil inlet and valve (3), derubber agent inlet and valve (4), rubber discharge port and valve (6), derubber agent-rubber seed oil mixing Solution outlet and valve (2), wherein there is a pipeline (9) in the tank body (1) to connect the derubber agent-rubber seed oil mixed solution outlet (2) to the bottom of the tank body; the tank body (1) is also provided with 3 auxiliary devices, namely derubberizing agent condensation reflux device (5), mechanical stirring device (7), heating coil (8).

Embodiment 2

[0024] Carry out the steps of the method for rubber seed oil derubberization in the sinking tank (1) that is specially used for rubber seed oil derubberization of the present invention of embodiment 1: the derubberizing agent that injects from the degumming agent inlet (4) and from rubber seed The crude rubber seed oil injected into the crude oil inlet (3) is injected into the sinking tank (1) at a ratio of 1:1-1:1.5 (volume ratio), and stirred and mixed by the stirring device (7) for 5 minutes, while heating the coil (8) Heat the mixed solution to 50-60°C, and then let it stand for 40-60 minutes. At this time, the rubber aggregates, precipitates, and adheres to the tank wall of the sinking tank; after that, the rubber seed oil-derubberizing agent solution passes through the pipeline (9), from the outlet (2) is pumped to the vacuum distiller; at 80-90 ° C, vacuum distillation under a pressure of 0.01MPa, reclaim the derubberizing agent, and obtain the rubber seed oil for derubb...

Embodiment 3

[0026] Get 540 liters of derubberizing agent that contains acetone 99%, and 800 liters (728 kilograms) of the rubber seed crude oil of squeezing, pour into sinking rubber tank (1), be heated to 55 ℃, stir 10 revolutions per minute, stir 5 minutes, then Let stand for 60 minutes. Afterwards, the derubberizing agent-rubber seed oil mixed solution was taken out, and vacuum distillation was carried out at 80° C. and 0.01 MPa to obtain 778 liters (708 kg) of derubberizing oil and 20 kg of rubber-rubber seed oil paste. The rubber seed oil after derubberization will not be drawn, and when heated to 280°C, the color of the oil will not turn black, and no carbon fiber will be precipitated.

Abstract

The invention discloses a method and a device for removing rubber from rubber seed oil. The method comprises: firstly, adding a rubber removing agent and the rubber seed oil into a rubber precipitation tank according to the proportion of 1:1-1:1.5, heating the rubber precipitation tank to be between 50 and 60 DEG C, mildly stirring for 5 minutes, standing for 40 to 60 minutes, and separating out, agglutinating and precipitating the rubber; secondly, pumping a mixed solution of the rubber seed oil and the rubber removing agent out of the rubber precipitation tank, recovering the rubber removing agent through reduced pressure distillation, and obtaining rubber seed oil after removal of the rubber; and thirdly, heating a tank body to be between 140 and 260 DEG C after rubber paste in the rubber precipitation tank is accumulated to certain quantity, softening the rubber, and exhausting the rubber from a rubber outlet at the bottom of the rubber precipitation tank. The rubber removing agent comprises 90 to 100 percent of acetone and 0 to 10 percent of water. The method is complete to remove the rubber, and the rubber removing agent can be recycled.

Description

technical field [0001] The invention relates to a method for derubberizing rubber seed oil, and to a rubber sinking tank specially used for the method. Background technique [0002] Rubber seed oil is a vegetable oil extracted from the seed of the rubber tree, the rubber seed. In southern Yunnan and Hainan Province of my country, there are large rubber tree planting areas, which produce hundreds of thousands of tons of rubber seeds every year, and tens of thousands of tons of rubber seed oil can be extracted. [0003] Rubber seed oil has a high degree of unsaturation and a reasonable ratio of fatty acids, so it has great potential as an industrial oil or as an edible oil. But the special component contained in rubber seed oil—rubber—is the main factor limiting the application of rubber seed oil. There is no patent on rubber seed oil derubberization at present. Among the published articles, there are two papers and a patent application publication (Hu Xiaohong, Liu Dachuan...
