Abstract
This utility model relates to the field of pulping technology, specifically a permanent magnet direct drive motor hydraulic pulper, including an inner shell. A scraping assembly is installed inside the inner shell. The scraping assembly includes a first scraping plate rotatably connected to the inner wall of the inner shell, a second scraping plate fixedly connected to the bottom of the first scraping plate, and an extension rod fixedly connected to the top of the first scraping plate. One end of the extension rod is fixedly connected to a connecting plate, and the bottom of the connecting plate is fixedly connected to an auger rod. Auger blades are fixedly connected to the side surface of the auger rod. The beneficial effects of this device are: through the first and second scraping plates, the inner wall of the inner shell, which is cylindrical in the upper part and conical in the bottom, can be effectively cleaned. This improves pulping efficiency and cleaning efficiency during production, preventing pulp residue on the inner wall of the inner shell and thus preventing mold growth on the inner wall of the inner shell when the machine is stopped.
