Embodiment 1

[0014] figure 1 The structural representation of the equipment that the dissolving method of shown turpentine adopts, wherein, dissolving pot 2 is provided with agitator, and this agitator includes the motor 3 that is installed on the top of dissolving pot 2 and the stirring shaft 4 that connects motor 3 output ends, stirs The other end of the shaft 4 extends into the dissolving pot 2; the lower part of the stirring shaft 4 is equipped with a paddle-type double blade 5, and the bottom end is connected with a turbine blade 6; the heating coil 7 is arranged on the paddle-type double blade around the stirring shaft 4 Between 5 and the turbine blade 6, the two ends of the heating coil 7 extend out of the dissolving pot 2 respectively.

[0015] The present embodiment provides necessary equipment for the dissolving of turpentine, especially the bottom of stirring shaft 4 is equipped with paddle type double blade 5, and the bottom end is connected with the structure that turbine blad...

Embodiment 2

[0017] The dissolving scheme of present embodiment rosin comprises the following specific steps:

[0018] Put the rosin into the preheating pot 1, preheat it to 70°C, then send it into the dissolving pot 2, start the motor 3 on the stirring device, and feed 350°C steam into the coil heater 7 to make the rosin Heating to 110°C, and then under this temperature condition, the pine resin is continuously stirred, sheared, broken and dissolved at a stirring speed of 80 rpm;

[0019] Wherein, the above-mentioned dissolving pot 2 is provided with a stirring device, and the stirring device includes a motor 3 installed on the top of the dissolving pot 2 and a stirring shaft 4 connected to the output end of the motor 3, and the other end of the stirring shaft 4 stretches into the dissolving pot 2; The bottom of 4 is equipped with paddle type double blade 5, and the bottom end is connected with turbine type blade 6; Heating coil 7 is arranged between paddle type double blade 5 and turbine...

Embodiment 3

[0022] The structure of the equipment adopted in the dissolving method of present embodiment rosin is as embodiment 2;

[0023] The method includes the following specific steps:

[0024] Put the turpentine into the preheating pot 1, preheat it to 70°C, and then send it into the dissolving pot 2, start the motor 3 on the stirring device, and feed 380°C heat conduction oil into the coil heater 7 to make the rosin Heating to 115°C, then at this temperature, the pine resin is stirred, sheared, broken, and dissolved at a stirring speed of 95 rpm.

[0025] Compared with the currently commonly used rosin dissolving method, every ton of rosin dissolved in this embodiment can reduce the discharge of waste water by about 1,000 kg, save 465,750 kcal of heat energy, and reduce production costs by about 160 yuan.

Abstract

The invention discloses a rosin dissolving method, belonging to the technical field of rosin processing. The rosin dissolving method comprises the following steps: conveying rosin into a pre-heating pot and pre-heating; then conveying the rosin into a dissolving pot which is equipped with a stirring device with shearing and crushing effects and heating by a coiled pipe heater; and continuously stirring, shearing, crushing and dissolving. A manner of utilizing the stirring device with shearing and crushing effects to stir rosin liquid is used for replacing a manner of stirring the rosin liquid by original open water steam, so that the utilization rate of the original open water steam is reduced and the emission amount of wastewater formed by the original open water steam is reduced; the steps of dissolving oil and water do not need to be additionally arranged, so that a processing flow of the rosin is simplified, the number of clarifying equipment is reduced, operation frequency of workers is reduced and the production cost is reduced; and meanwhile, the manner of replacing heating utilizing the original open water steam is used for heating the rosin, so that heat energy needed by rosin heating is reduced.

Description

technical field [0001] The invention belongs to the technical field of rosin processing, and in particular relates to a method for dissolving rosin. Background technique [0002] At present, the common dissolving method of rosin in the process of turpentine processing is: input turpentine from the resin storage tank into the hopper with a spiral groove, then enter the melting pot, and then add molten oil and water, put in an appropriate amount of oxalic acid, heat and stir with open water vapor melted. However, using this dissolving method has the disadvantages of high production energy consumption, water vapor consumption, and a large amount of waste water. On average, the pressure consumed per ton of rosin dissolved is about 0.2 MPa, water vapor is about 300 kg, and waste water is about 500 kg. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for dissolving rosin, which solves the shortcomings of high ...
