Description

Technical Field

[0001] The utility model relates to the field of cylindrical screens, in particular to a papermaking cylindrical screen. Background Art

[0002] Papermaking is an important invention of the working people in ancient China. It is divided into two forms: mechanical and manual. The mechanical process is carried out continuously on a papermaking machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and initially dehydrated on the wire part of the papermaking machine to form wet paper sheets. The wet paper sheets are then pressed and dehydrated, and then dried into paper. The manual process uses a frame with a polyester mesh or a copper mesh to copy the fibers dispersed and suspended in the water into wet paper sheets, which are pressed and dehydrated, and then dried or baked into paper. The existing clean papermaking uses a cylindrical screen to double filter and screen the material.

[0003] The working part of the drum screen is cylindrical, and the whole screen rotates around the axis of the cylinder. The axis is usually installed at a small inclination angle. The material is fed from one end of the cylinder, the fine-grade material passes through the sieve holes on the working surface of the cylinder, and the coarse-grained material is discharged from the other end of the cylinder. The drum screen has a very low rotation speed, stable operation, and good power balance. However, its sieve holes are easily blocked, the screening efficiency is low, the working area is small, and the productivity is low. Therefore, it is generally not used as a sorting equipment in mineral processing plants. Due to its good balance and slow rotation speed, it is suitable for processing equipment of relatively soft materials, especially in the papermaking process, the drum screen can be used for screening and sorting to drain the pulp on the paper.

[0004] Existing drum screens often use a large motor connected to the main shaft to drive the entire device to move. The motor drives the internal screen drum to rotate and generate vibration. The strong vibration will affect the overall assembly of the drum screen, and long-term vibration will reduce the service life of the drum screen.

[0005] Therefore, it is necessary to provide a papermaking drum screen to solve the above technical problems. Utility Model Content
