Description

Technical Field

[0001] The utility model relates to the technical field related to equipment for cleaning a paper machine, and in particular to a waterproof structure. Background Art

[0002] "Wet end of paper machine" usually refers to a series of parts in paper machine that are closely related to water, such as pulp processing, forming and dehydration. In the wet end of paper machine, pulp is evenly distributed to the wire part through the headbox, and wet paper web is initially formed through dehydration, water filtration and other processes. The operation status of this part has an important impact on the quality, performance and production efficiency of paper. And the cleaning of wet end of paper machine is a very important link in the papermaking process. Since there will be deposition and residue of fiber, filler, chemical additives and other substances in the wet end, it is easy to cause equipment blockage, reduced operation efficiency, reduced paper quality and other problems.

[0003] The mobile trolley for wet end cleaning of paper machines is a movable device specially designed for the wet end cleaning of paper machines. It is usually equipped with the tools, nozzles, detergent storage devices, power and control systems required for cleaning. This mobile trolley can be flexibly moved in different positions of the wet end of the paper machine, making it convenient for operators to reach the parts that need to be cleaned for precise and efficient cleaning operations, thereby improving cleaning efficiency and ensuring the normal operation of the paper machine and paper quality.

[0004] In the mobile trolley for wet-end cleaning of paper machines, the guide wheel is a wheel that plays a guiding and supporting role.
