Description

Technical Field

[0001] The utility model relates to a dredging device, in particular to a condensed water material channel dredging device used for distillation in polymerized rosin production. Background Art

[0002] Polymerized rosin is a light yellow transparent solid made from gum rosin through acid isomerization and cationic catalytic polymerization. The most advanced production process at home and abroad is 200# solvent oil as solvent and sulfuric acid-zinc chloride method as polymerization process. The gum rosin is dissolved in 200# solvent, concentrated sulfuric acid is added dropwise for isomerization, and zinc chloride is added to catalyze polymerization. The product is then hydrolyzed and washed, distilled and desolvated, and then oligomers are removed by vacuum mixing. Finally, the product is packaged and granulated.

[0003] However, during the distillation process, the vacuum tube is connected to the bottom discharge port of the condenser connected to the rear air duct of the oligomer mixture separation pot. When the oligomer mixture is removed by vacuum extraction during distillation, the oligomer mixture is not completely drawn into the oligomer mixture separation pot. As a result, a portion of the rosin oil with a lower boiling point in the oligomers enters the condenser through the air duct on the separation pot in the form of a gas-liquid mixed phase. Because the rosin oil is very viscous and has a low temperature, it blocks the material channel of the condenser when it is cold. When the channel is blocked, distillation to remove the oligomer mixture cannot be carried out and it needs to be unblocked before distillation can be resumed. In winter when the temperature is low, the channel is often blocked, seriously affecting production efficiency. Utility Model Content

[0004] In order to overcome the disadvantage of the above-mentioned prior art that rosin oil with a low boiling point is easily condensed and clogged in the condenser during use, the technical problem of the utility model is to provide a condensate material channel clearing device for polymerized rosin production distillation that can effectively prevent rosin oil from clogging the material channel.

[0005] Technical solution: A condensate material channel clearing device for distillation of polymerized rosin production, comprising an oligomer mixing pot, an enamel air duct, a water tank, a refrigerator, a partition, a jacket, a water pump and a reflux pipe. The top of the oligomer mixing pot is fixedly connected to an enamel air duct for the passage of the oligomer mixture, the bottom of the enamel air duct is fixedly connected to a water tank for storing cooling water, the bottom of the water tank is fixedly connected to a refrigerator for cooling the cooling water, the refrigerator is fixedly connected to a partition for preventing the cooling water from freezing, the enamel air duct is fixedly connected to a jacket, the cavity between the jacket and the enamel air duct is a place for heat exchange between the cooling water and the enamel air duct, the water tank is fixedly connected to a water pump for extracting cooling water from the water tank, a reflux pipe for cooling water reflux is provided between the jacket and the water tank, one end of the reflux pipe is fixedly connected to the top of the jacket, and the other end of the reflux pipe is fixedly connected to the water tank.

[0006] Furthermore, it also includes a servo motor, a rotating shaft, a gear, a gear ring and a stirring blade. The servo motor is fixedly connected to the bottom of the water tank, the output shaft of the servo motor is fixedly connected to the rotating shaft, the top of the rotating shaft is fixedly connected to the gear, the top of the partition is rotatably connected to the gear ring, the gear is meshed with the gear ring, the stirring blades are distributed in a ring on the gear ring, and the gear ring is fixedly connected to the stirring blades to stir the cooling water in the water tank and assist the refrigerator to cool the cooling water in the water tank.

[0007] Furthermore, it also includes a guide spiral blade, which is located in the jacket and fixedly connected to the jacket to guide the cooling water pumped out by the water pump to the return pipe, thereby improving the heat conversion efficiency of the cooling water.

[0008] Furthermore, it also includes heat insulation cotton, which is fixedly connected to the outside of the jacket to prevent the device from increasing the temperature of the workplace during use.

[0009] Furthermore, a disturbance block is included. The disturbance block is distributed in an annular manner on the inner side wall of the water tank and is used to prevent the cooling water in the water tank from forming a vortex. The disturbance block is fixedly connected to the water tank.

[0010] Furthermore, an observation window is included. The jacket is fixedly connected with an observation window for observing the working condition of the cooling water in the jacket.

[0011] The beneficial effects of the utility model are as follows: the utility model uses a water pump to draw condensed water in the water tank into the cavity formed by the enamel air guide pipe and the jacket for circulation, so that the rosin oil with a lower boiling point in the oligomer is condensed into liquid when passing through the enamel air guide pipe and flows back to the oligomer mixing pot, thereby effectively preventing the rosin oil from clogging the material channel, thereby achieving the effect of improving production efficiency.

[0012] The utility model drives the rotating shaft through a servo motor, and the rotating shaft drives the gear to drive the gear ring to rotate, which in turn drives the stirring blade to rotate. The stirring blade rotates and stirs the cooling water in the water tank, which not only increases the contact area between the cooling water and the refrigerator, improves the cooling effect, but also prevents the cooling water from locally freezing at low temperatures.

[0013] The utility model guides the cooling water pumped out by the water pump to the return pipe through the guide spiral blade, ensuring that the cooling water forms an orderly flow path in the jacket, improving the contact efficiency between the cooling water and the enamel air guide pipe, accelerating the heat exchange process, and thus improving the heat conversion efficiency.

DETAILED DESCRIPTION

[0019] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0020] Example: A condensate material channel dredging device for distillation of polymerized rosin production, such as Figure 1-4 As shown, it includes a oligomer mixing pot 1, an enamel air duct 2, a water tank 3, a refrigerator 4, a partition 5, a jacket 6, a water pump 7 and a reflux pipe 8. The top of the oligomer mixing pot 1 is fixedly connected with an enamel air duct 2 for the passage of the oligomer mixture. The size of the enamel air duct 2 is 5 meters in inner diameter. The bottom of the enamel air duct 2 is fixedly connected to a water tank 3 for storing cooling water, and the bottom of the water tank 3 is fixedly connected to a refrigerator 4 for cooling the cooling water. The refrigerator 4 is a semiconductor refrigerator, and a baffle 5 for preventing the cooling water from freezing is fixedly connected to the refrigerator 4. A jacket 6 is welded on the enamel air duct 2. The cavity between the jacket 6 and the enamel air duct 2 is a place for heat exchange between the cooling water and the enamel air duct 2. A water pump 7 for extracting cooling water from the water tank 3 is fixedly connected to the water tank 3. There is a water pump 7 between the jacket 6 and the water tank 3. The return pipe 8 for cooling water return has one end fixedly connected to the top of the jacket 6, and the other end of the return pipe 8 is fixedly connected to the water tank 3. It also includes a guide spiral sheet 14, which is located in the jacket 6 and welded to the inner wall of the jacket 6 to guide the cooling water pumped out by the water pump 7 to the return pipe 8, so as to improve the heat conversion efficiency of the cooling water. It also includes insulation cotton 15, which is fixedly connected to the outside of the jacket 6 to prevent the device from increasing the temperature of the workplace during use.

[0021] During the distillation process of polymerized rosin, the oligomeric mixture enters the enamel air duct 2 through the enamel air duct 2 on the top of the oligomeric mixing pot 1. The bottom of the enamel air duct 2 is connected to a water tank 3, and cooling water is stored in the water tank 3. After the water pump 7 is started, the cooling water is pumped out from the water tank 3 and circulated through the cavity between the jacket 6 and the enamel air duct 2. The outside of the jacket 6 is wrapped with heat-insulating cotton 15, which reduces the impact of the device on the temperature of the workplace during operation and maintains the stability of the working environment. A guide spiral 14 is fixed inside the jacket 6. The guide spiral 14 can guide the cooling water pumped out by the water pump 7 to the return pipe 8, ensuring that the cooling water forms an orderly flow path in the jacket 6, thereby improving the cooling water and the enamel. The contact efficiency of the air duct 2 accelerates the heat exchange process, thereby improving the heat conversion efficiency. The cooling water exchanges heat with the steam in the enamel air duct 2, so that the rosin oil with a lower boiling point in the oligomer is condensed into liquid and refluxed back to the oligomer mixing pot 1, thereby effectively preventing the rosin oil from clogging the material channel, thereby achieving the effect of improving production efficiency. As the refrigerator 4 installed at the bottom of the water tank 3 continues to work, the temperature of the cooling water is reduced. In order to prevent the cooling water from freezing at extremely low temperatures, a partition 5 is provided above the refrigerator 4 to insulate and prevent freezing. After the heat exchange is completed, the cooling water flows back to the water tank 3 through the return pipe 8 at the top of the jacket 6, thereby forming a closed-loop cooling water circulation system.

[0022] like Figure 1 、 2 As shown in FIG4 , it also includes a servo motor 9, a rotating shaft 10, a gear 11, a gear ring 12 and a stirring blade 13. The servo motor 9 is fixedly connected to the bottom of the water tank 3, the output shaft of the servo motor 9 is fixedly connected to the rotating shaft 10, the top of the rotating shaft 10 is fixedly connected to the gear 11, the top of the partition 5 is rotatably connected to the gear ring 12, the gear 11 is engaged with the gear ring 12, the stirring blade 13 is distributed in an annular manner on the gear ring 12, and the gear ring 12 is fixedly connected to the stirring blade 13 to stir the cooling water in the water tank 3 and assist the refrigerator 4 in cooling the cooling water in the water tank 3. It also includes a disturbance block 16. The disturbance block 16 for preventing the cooling water in the water tank 3 from forming vortexes is distributed in an annular manner on the inner side wall of the water tank 3. The disturbance block 16 is made of stainless steel alloy and is fixedly connected to the water tank 3.

[0023] In order to improve the cooling efficiency, a rotating shaft 10 driven by a servo motor 9 is provided at the bottom of the water tank 3. A gear 11 is installed on the rotating shaft 10. The gear 11 is engaged with a gear ring 12 above the partition 5. A stirring blade 13 is fixed on the gear ring 12. When the servo motor 9 is working, the stirring blade 13 rotates to stir the cooling water in the water tank 3, which not only enhances the contact area between the cooling water and the refrigerator 4 and improves the cooling effect, but also prevents the cooling water from forming local ice at low temperatures, further ensuring the smooth progress of the condensation process. The disturbance blocks 16 distributed in an annular manner on the inner side wall of the water tank 3 are used to prevent the cooling water in the water tank 3 from forming vortices during the circulation process. The vortices will reduce the flow efficiency of the cooling water and affect the heat exchange effect. The disturbance blocks 16 break the formation conditions of the vortex and ensure the uniform distribution and effective flow of the cooling water.

[0024] like Figure 1 As shown, an observation window 17 is also included. The jacket 6 is fixedly connected to the observation window 17 for observing the working condition of the cooling water in the jacket 6.

[0025] An observation window 17 is provided on the jacket 6, allowing the operator to directly observe the working condition of the cooling water in the jacket 6. Through the observation window 17, the operator can promptly discover and deal with problems such as insufficient cooling water flow and abnormal temperature, thereby ensuring the continuity and stability of the condensation process.
