Description

Pulp molding raw material filtering and screening device Technical Field The utility model relates to the technical field of pulp molding raw material filtering and screening, in particular to a pulp molding raw material filtering and screening device. Background In the production of pulp molded articles, filtration screening of pulp molded raw materials is a crucial element, which is directly related to the quality and performance of subsequent articles. At present, although the pulp molding raw material filtering and screening device in the market can meet basic filtering and screening requirements to a certain extent, a plurality of problems to be solved still exist in the actual operation process, the problems seriously affect the production efficiency and the product quality, and the production cost of enterprises is increased. The existing filtering and screening device is easy to accumulate impurities and raw materials which do not pass through screening in the long-term use process of the filtering and screening box.
