[0016] Heating device 11 is a biomass thermal oil boiler, which heats the thermal oil by burning fuel to generate steam, which then heats the first pressing pot 2, the second pressing pot 4, the dissolving pot 1, the clarifying pot 3, and the distillation pot 5. The waste port of the dissolving pot 1 is connected to the feed port of heating device 11 through a waste conveying device.

[0017] The vent of the clarifying pot 3 is connected to the condenser 9 through the clarifying pot condensing pipe, and the clarifying pot condensing pipe is equipped with a clarifying condensing valve 13; the vent of the distillation pot 5 is connected to the condenser 9 through the distillation pot condensing pipe, and the distillation pot condensing pipe is equipped with a distillation pot condensing valve 14.

[0018] The first oil-water separator 7 and the second oil-water separator 10 typically use a static stratification method for oil-water separation. The upper layer of grease is discharged from the outlet, and the lower layer of wastewater is discharged from the drain. The remaining components are all commonly available models and have not been modified.

[0020] Example 3 A dust removal device is also installed between the heating exhaust stack and the heating unit 11. To improve the quality of the exhaust gas, the dust removal device includes a cyclone dust collector, a bag filter dust collector, and a water film dust collector. Through triple dust removal, the exhaust gas is guaranteed to meet emission standards.

[0021] The operating steps for the above-mentioned rosin production equipment are as follows: (1) Preparation of coarse material: waste, plastic, resin and other impurities in the rosin raw material are sorted and removed to obtain coarse material; (2) Dissolving the crude material: The crude material is put into the dissolving pot 1, and turpentine oil is added from the turpentine oil storage tank 8 into the dissolving pot 1. Then, the mixture is heated and stirred to make the turpentine oil and the crude material blend together to obtain the intermediate. (3) Intermediate extraction: After the turpentine oil and crude material are fused together to form an intermediate, stirring is stopped. The intermediate is naturally clarified in the dissolving pot 1 to separate the intermediate from the impurities and extract the intermediate. The remaining impurities are heated and stirred until most of the turpentine oil in the impurities evaporates, leaving residue. The evaporated gas enters the first oil-water separation device 7, the condensed turpentine oil is sent to the turpentine oil storage tank 8, the water is sent to the wastewater pool 12, and the residue is sent to the heating device 11 through the waste outlet of the dissolving pot 1 for combustion and heating. (4) Separation of resin and liquid: The intermediate is added into the first pressing pot 2, pressurized, heated and filtered to obtain rosin liquid; (5) Secondary clarification: Pulp the rosin into the clarification pot 3, heat it to 90-95℃, and let it stand for 6-8 hours until the rosin liquid and water separate into layers on their own. Extract the upper layer of rosin liquid. Open the clarification condenser valve 13, and the steam in the clarification pot enters the condenser 9. After the water-containing turpentine oil is condensed in the condenser 9, it is separated by the second oil-water separation device 10. The turpentine oil is sent to the turpentine oil storage tank 8, the water is sent to the wastewater pool 12, and the non-condensable waste gas is discharged through the condenser exhaust port 15. (6) Resin distillation: After removing impurities, the pine resin extracted in step (5) is pressed into the distillation pot 5 through the second pressure pot 4. The distillation pot 5 is heated to distill out the water and turpentine oil to obtain rosin liquid. At the same time, the distillation pot condenser valve 14 and vacuum device on the pipe connecting the exhaust port of the distillation pot 5 and the condenser 9 are opened. The distilled gas enters the condenser 9. The water-containing turpentine oil formed after condensation in the condenser 9 is separated by the second oil-water separation device 10. The turpentine oil is sent to the turpentine oil storage tank 8, the water is sent to the wastewater pool 12, and the non-condensable waste gas is discharged through the condenser exhaust port 15. (7) Cooling and shaping: After distillation, stop heating the distillation pot 5, open the bottom outlet valve of the distillation pot 5, and inject the rosin liquid into the rosin storage tank 6 for cooling and delivery.

[0022] The residue produced by the dissolving pot 1 of this invention can be recycled as fuel for the heating device 11. The heating device 11 heats the dissolving pot 1, distillation pot 5, clarification pot 3, first pressing pot 2, and second pressing pot 4, effectively utilizing the waste generated during rosin production and greatly reducing costs. The distillation pot 5 and clarification pot 3 are connected to the condenser 9. The oily condensate produced by the condenser 9 is treated by the second oil-water separator 10, and the turpentine is recycled to the turpentine storage tank 8 for reuse. The wastewater is recycled to the wastewater pool 12 to provide cooling water for the condenser tubes of the condenser 9. At the same time, the oily distillate produced during the heating process of the dissolving pot 1 can also be separated from the wastewater by the first oil-water separator 7. The turpentine is recycled to the turpentine storage tank 8, and the wastewater is recycled to the wastewater pool 12.

[0023] It should be noted that the connecting pipes between the components also have control valves, but they are not specifically marked in the attached drawings.

[0024] It should be noted and understood that various modifications and improvements can be made to the present invention as described in the above description without departing from the spirit and scope of the claims. Therefore, the scope of the claimed technical solutions is not limited to any specific exemplary teachings given.
