Description

Still for extracting rosin

The utility model belongs to the purification techniques field of natural resin.

Refinement mainly contains two kinds of methods at present to rosiny, and a kind of is steaming process, and a kind of is drip method steaming process production safety, quality product height and stable, but the equipment complexity, energy dissipation is big, construction investment is big; The method of dripping production less investment, equipment is simple but produce dangerous, fire hazardous, directly fire is heated, because temperature is wayward, it is inhomogeneous to be heated, poor product quality, and the unstable inventor has at present invented a kind of new refinement rosiny method, this method synthesis steaming process and the advantage of method of dripping, the quality product height of make that whole process flow is simple, equipment simple, production safety, power consumption are low, producing.Fig. 2 is to use this method to produce the rosiny process flow sheet.A visual plant in rosin production is a still pot, and the still pot that uses in the steaming process and the method for dripping is owing to adopt direct heating, and its structure does not obviously fit into the production requirement of new method.

The purpose of this utility model is will provide a kind of can be adapted to technical process requirement among Fig. 2, and the rosin that need are processed can carry out indirect heating, distiller simple in structure.

The purpose of this utility model realizes with the following methods.The distiller shell is divided into two portions, shell and interior cover, in be enclosed within the inboard of shell, in distiller, put and be provided with opening for feed, put fragrant mouthful in the bottom of interior cover, weep pipe feeds cover in the distiller, and distiller shell and interior cover form an oil jacket layer, adorn thermal oil in the oil jacket layer, the thermal oil circulation tube passes to overlap in the distiller and is connected with the oil jacket layer, on the distiller shell heat conductive oil inlet is arranged, and leads to interior cover.The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 structure iron of the present utility model;

Fig. 2 rosin refining technique schema;

Fig. 3 is the structure iron of rosin treater (2) among Fig. 2;

Fig. 4 is the schematic circuit diagram of two-position controller among Fig. 2 (11).

Among the figure: 1-distiller, 2-rosin treater, 3-condenser, the 4-heating-range, the 5-basket filter, 6-adds feed bin, the 7-flue, 8,9, the 10-control valve, the 11-two-position controller, 12-holds slag chute, and 13-holds fragrant groove, the excellent oil groove of 14-, oil groove among the 15-, 16-heavy oil groove, 17-quirk, 21-is put fragrant mouthful, 22-distiller shell, 23-evacuation port, 24-opening for feed, 25-oil gas vent, the 26-mouth of pipe that drips, 27-thermal oil inlet, 28-oil jacket layer, 29-thermal oil circulation tube, the 30-thermometer wrap, 31-back-up block, the outlet of 32-thermal oil, cover in the 33-distiller, 34,35, the 36-pipeline, 41-treater shell, the 42-charging opening, 43-step-down gear, 44-add water and air outlet, 45-water jacket layer, 46-thermometer wrap, 47-agitator, the 48-discharge port, 49-dewatering outlet, 50-slag-drip opening, cover in the 51-treater, DF _i(i=1,2,3 ... 6)-and control valve, t-multiple contact electric contact thermometer, SJ-transistor time relay, J-intermediate relay, D-pilot lamp.

Distiller (1) and rosin treater (2) all adopt chuck layer structure, dress thermal oil in the oil jacket layer (28), water jacket layer (45) dress water, be beneficial to even heating and prevent the too fast local superheating phenomenon that causes of temperature rising, the inboard oil jacket layer (28) of distiller (1) has thermal oil circulation tube (29) to pass cover (33) in the distiller, make the thermal oil in the oil jacket layer (28) carry out even heating to the material that overlaps (33) in the distiller more equably, between cover (33) bottom and distiller shell (22) bottom back-up block (31) is arranged in the distiller, thermometer wrap (30) skewer is gone into cover (33) in the distiller, control valve DF _i(i=1,2 ... closing 6), open by two-position controller (11) control, control valve (DF _i) the employing magnetic valve.

Operating process of the present utility model can be refined the rosiny process by the technical process of Fig. 2 and be set forth:

1, rosin is refining:

(1), heating-range (4) is lit a fire, the water of water jacket layer (45) lining in the rosin treater (2) is heated to 85 ℃-95 ℃, in the treater of rosin treater (2), add an amount of dissolving oil, water, oxalic acid again in the cover (51), start agitator (47), under the stirring that does not stop, add rosin to be processed by adding feed bin (6).

(2), treat that rosin all dissolves, restir 10 minutes so that rosin fully contacts with oxalic acid aqueous solution and produce cleaning function, stops to stir, and is incubated 4 hours, to finish the clarification operation;

(3), open rosin treater (2) slagging coutrol valve (10), drain water and rosin slag, closed control valve (10) is opened control feeding valve (8) again, refined rosin is entered in the distiller (1) distillation of heating through basket filter (5).

2, distillation

(1), be heated when the thermal oil of distillation in (1), during 130 ℃-135 ℃ of temperature arrival.Intermediate relay (J ₁) action, open control valve (DF ₁), begin to drip, because hydraulic pressure and caliber weighing apparatus are fixed, control the amount of dripping automatically.Per minute heats up 1 ℃, to 160 ℃-165 ℃, has steamed excellent oil, needs about 40 minutes approximately;

(2), when temperature to 160 ℃-165 ℃, intermediate relay (J ₂) action, closed control valve (DF ₂), begin to strengthen and drip, simultaneously control valve (DF ₃) close control valve (DF ₄) open, begin middle oil, and strengthen firepower, making heat-up rate is 1.5 ℃/minute;

(3), when temperature is raised to 180 ℃, intermediate relay (J ₃) action, closed control valve (DF ₄), open control valve (DF ₅), begin heavy oil;

(4), when temperature is raised to 185 ℃, be incubated 2-3 minute, transistor time relay (SJ) action, closed control valve (DF ₂), stop to drip boiling-off 3-5 minute;

(5), when temperature to 195 ℃-200 ℃, intermediate relay (J ₄) action, open control valve (DF ₆), the rosin that refining is good is put into and is held fragrant groove (13), when waiting to be as cold as 170 ℃ of left and right sides, packs, and a fragrant cycle of refining promptly finishes.

Because the utility model has adopted oil lagging layer structure, the heating of rosin is carried out in oil is molten, and make inner sleeve around be heated simultaneously with the center, make uniform heat distribution and do not have the hot-spot phenomenon, greatly improved product quality.
