[0032] The following further describes this application in detail Figures 1-4 in conjunction with the appended

[0033] An embodiment of this application discloses a decolorization kettle.

[0034] Referring to Figures 1-3 , a decolorization kettle includes a reaction kettle 1. A discharge port 2 is opened at the bottom of the reaction kettle 1. A discharge valve 3 is arranged at the inner bottom of the discharge port 2. A blanking auger 4 is rotatably connected inside the discharge port 2. The top of the blanking auger 4 extends to the inner bottom of the reaction kettle 1 and is fixedly connected with a cutting knife 5. The bottom of the blanking auger 4 passes through the reaction kettle 1 and is fixedly connected with a first bevel gear 6. The bottom of the reaction kettle 1 is fixedly connected with a blanking motor 7. The output end of the blanking motor 7 is fixedly connected with a second bevel gear 8 that meshes with the first bevel gear 6.

[0035] During use, first, when the discharge valve 3 is opened to guide the raw materials inside the reaction kettle 1 to pass through the discharge port 2 and be discharged, the precipitates and other impurities generated in the raw materials gather towards the top of the discharge port 2 under the action of gravity and accumulate at the top of the discharge port 2 to form a blockage. At this time, by starting the blanking motor 7 to drive the second bevel gear 8 to mesh with the first bevel gear 6, and making the first bevel gear 6 drive the blanking auger 4 and the cutting knife 5 to rotate synchronously, so that the cutting knife 5 stirs and cuts the precipitates and other impurities accumulated at the top of the discharge port 2, making the precipitates blocked at the top of the discharge port 2 loosen and enter the inside of the discharge port 2. At the same time, the blanking auger 4 is used to rotate and push the precipitates entering the inside of the discharge port 2 and discharge them along the length direction of the discharge port 2 from the inside of the reaction kettle 1. In this way, it effectively reduces the situation that impurities are generated inside the reaction kettle 1 to block the discharge port 2 and affect the normal operation of the reaction kettle 1, and improves the practicability of the device.

[0036] Referring to Figure 2 andFigure 4 At the inner top of the reaction kettle 1, there is an installation bin 9. Inside the reaction kettle 1, a first stirring rod 10 is rotatably connected. At the top of the reaction kettle 1, a stirring motor 11 is fixedly connected. One end of the first stirring rod 10 passes through the installation bin 9 and extends into the reaction kettle 1, and is fixedly connected to the output end of the stirring motor 11;

[0037] Among them, scraping rods 12 are symmetrically and fixedly connected to the bottom of the first stirring rod 10, and one end of each scraping rod 12 is in contact with the inner side of the reaction kettle 1;

[0038] Moreover, three second stirring rods 13 are evenly and rotatably connected inside the reaction kettle 1. The three second stirring rods 13 are arranged in a circular pattern around the first stirring rod 10. Inside the installation bin 9, a transmission assembly for driving the second stirring rods 13 to rotate is installed;

[0039] Moreover, the transmission assembly includes a driven gear 14 fixedly connected to the top of the second stirring rod 13. One end of the first stirring rod 10 is fixedly connected with a driving gear 15 that meshes with the driven gear 14. Both the driven gear 14 and the driving gear 15 are installed inside the installation bin 9;

[0040] Moreover, the diameter of the driving gear 15 is twice that of the driven gear 14.

[0041] During use, first, start the stirring motor 11 to drive the first stirring rod 10 to rotate, and drive the raw materials inside the reaction kettle 1 to rotate and stir. At the same time, the first stirring rod 10 drives the driving gear 15 to mesh with the driven gear 14. Utilizing the characteristic that the diameter of the driving gear 15 is twice that of the driven gear 14, drive the driven gear 14 to drive the second stirring rods 13 to rotate at high speed. At the same time, the three second stirring rods 13 increase the stirring range of the first stirring rod 10, making the raw materials inside the reaction kettle 1 stirred more evenly. And while the first stirring rod 10 rotates, the first stirring rod 10 drives the two scraping rods 12 to rotate and move along the inner wall of the reaction kettle 1, and scrape off the raw materials and foreign matters adhered to the inner side of the reaction kettle 1, effectively reducing the adhesion of raw materials and foreign matters to the inner side of the reaction kettle 1 and improving the practicability of the device.

[0042] Refer to Figure 1 and Figure 2 , a heat-insulating rock wool 16 is fixedly sleeved on the outer side of the reaction kettle 1.

[0043] During use, by arranging the heat-insulating rock wool 16 to form a protective layer on the outer side of the reaction kettle 1, it reduces the situation that people directly contact the outer side of the reaction kettle 1 and get scalded. At the same time, it effectively reduces the heat exchange inside and outside the reaction kettle 1 and improves the heat utilization efficiency inside the reaction kettle 1.

[0044] Refer to Figure 1 and Figure 2 , a polymer nano-ceramic polymer coating is coated on the inner side of the reaction kettle 1.

[0045] During use, by setting the polymer nano-ceramic polymer coating, a high-temperature resistant and anti-corrosion protection layer is formed on the inner side of the reaction kettle 1, effectively extending the service life of the device.

[0046] The implementation principle of a decolorization kettle in this embodiment is as follows: First, raw materials are introduced into the reaction kettle 1, and the stirring motor 11 is started to drive the first stirring rod 10 to rotate, driving the raw materials inside the reaction kettle 1 to rotate and stir. At the same time, the first stirring rod 10 drives the driving gear 15 to mesh with the driven gear 14, and using the characteristic that the diameter of the driving gear 15 is twice that of the driven gear 14, the driven gear 14 is driven to drive the second stirring rod 13 to rotate at high speed. At the same time, the three second stirring rods 13 are used to increase the stirring range of the first stirring rod 10, making the raw materials inside the reaction kettle 1 stirred more evenly. And while the first stirring rod 10 rotates, the first stirring rod 10 drives the two scraping rods 12 to rotate and move along the inner wall of the reaction kettle 1, scraping off the raw materials and foreign matters adhered to the inner side of the reaction kettle 1;

[0047] Then, by opening the discharge valve 3, the raw materials inside the reaction kettle 1 are guided to pass through the discharge port 2 and discharged. The precipitates and other impurities generated in the raw materials gather towards the top of the discharge port 2 under the action of gravity and accumulate at the top of the discharge port 2 to form a blockage. At this time, the feeding motor 7 is started to drive the second bevel gear 8 to mesh with the first bevel gear 6, and the first bevel gear 6 drives the feeding auger 4 and the cutting knife 5 to rotate synchronously. Thus, the cutting knife 5 stirs and cuts the precipitates and other impurities accumulated at the top of the discharge port 2, making the precipitates blocked at the top of the discharge port 2 loosen and enter the inside of the discharge port 2. At the same time, the feeding auger 4 rotates to push the precipitates entering the inside of the discharge port 2 and discharges them from the inside of the reaction kettle 1 along the length direction of the discharge port 2.
