Description

Technical Field

[0001] The present application relates to the technical field of screen drums, and in particular to a screen drum for a pulping machine in the papermaking industry. Background Art

[0002] In the papermaking industry, pulp generally needs to be purified and screened during the papermaking process. In order to improve the screening effect of pulp, a pressure screen is often used to filter and screen the pulp. On the one hand, the pressure screen can remove dust and impurities in the pulp, and on the other hand, it can evenly disperse the pulp to create a uniformly dispersed fiber suspension to ensure better dispersion of the pulp. Usually, the pressure screen consists of a body, a transmission device, a screen drum, a rotor, etc., among which the screen drum is the core structure of the pressure screen, and the performance of the screen drum directly affects the working performance of the pressure screen.

[0003] When the existing screen drum is in use, pulp is usually fed from the top of the screen drum. The high-speed rotation of the screen drum causes the pulp to be subjected to centrifugal force and screen out impurities in the pulp through a large number of screen slots opened on the side wall of the screen drum. The pulp after impurity removal is then discharged through the pulp outlet at the bottom, thereby achieving purification and screening of the pulp.

[0004] However, when using the above-mentioned method for screening and removing impurities, since the screen slots of the screen drum are generally small in size, after long-term use, some pulp often adheres to the inner wall of the screen drum while the impurities are removed through the screen slots, causing blockage of the screen slots, thereby reducing the efficiency of impurity removal and making cleaning difficult. Therefore, those skilled in the art have provided a screen drum for a pulping machine in the papermaking industry to solve the problems raised in the above-mentioned background art.
