Next, heating water tank 7 heats the water inside into steam, which is then introduced into the outer cooking tank 2 to heat the inner cooking tank 1. Motor 3 drives stirring rod 13 to rotate. After cooking, the wood pulp paper separates into impurities and wood pulp. Then, baffle 17 moves down to allow the wood pulp solution to pass through conveying pipe 8 into washing drum 9. Filter screen 16 initially separates some impurities. Finally, baffle 17 re-seals filter screen 16 and discharges the material. Pipe 15 is opened, and rinsing fluid is introduced. Under the action of cleaning plate 14, the impurities flushed out by the rinsing fluid are discharged through discharge pipe 15. The wood pulp solution passing through conveying pipe 8 is cooled by cooling water supplied by water pump 5 in cooling pipe 6. The cooling water, after absorbing heat, enters heating water tank 7 and is heated into steam before being introduced into cooking tank 2. Then, motor 2 19 drives auger 20 to rotate and transport the wood pulp solution. When the wood pulp solution passes through filter screen 21, it will be separated from the impurities again and fall into collection box 10. Impurities that do not pass through filter screen 21 will be discharged from discharge port 11 by auger 20.
