Description

Technical Field

[0001] The utility model relates to the technical field of paper machine cleaning equipment, in particular to a high- and low-pressure cleaning device and system for a paper machine. Background Art

[0002] The paper machine is mainly composed of mesh, pressing and drying parts. During the operation of the paper machine, the pulp spread on the mesh and felt is gradually pressed and dried to form. Therefore, a large amount of pulp fiber often remains on the mesh, which will have an adverse effect on the papermaking process and the quality of the paper sheets. It is easy to contaminate the forming mesh, felt and dryer mesh, adhere to the pipes of the paper machine and make it difficult to clean, and be brought into the paper surface and affect the quality of the paper sheets. Therefore, whether the forming mesh, felt and dryer mesh are clean directly affects the quality and production efficiency of the paper, and needs to be cleaned and maintained regularly.

[0003] Traditional cleaning pump stations use two different pump stations to clean the forming mesh and felt cloth, and high-pressure cleaning or low-pressure cleaning is adopted according to the needs of use. Since low-pressure cleaning usually cannot provide sufficient cleaning force, high-pressure cleaning is required to assist. In other cases, high-pressure cleaning is not required to clean the equipment online. However, setting up two different pump stations not only requires a large space for installation and is limited in use, but also the two pump stations consume a lot of energy, increasing production costs.

[0004] There is no effective solution yet for the problems in related technologies such as requiring a large installation space, limited usage, high energy consumption and increased costs. Utility Model Content
