[0002] With the continuous development and progress of the pulp and paper making technology, the requirements for equipment performance are also getting higher and higher. As one of the important equipment in the pulping process, the performance of the inner-flow pressure screen directly affects the purification effect of the pulp and the production cost. And as one of the key components in the inner-flow pressure screen, the assembly quality and accuracy of the scraper assembly directly affect the operation stability and screening efficiency of the equipment. Therefore, higher requirements are put forward for the assembly of the inner-flow screen scraper.

[0003] For the assembly of some scraper rotors, the approximate dimensions are first measured manually for assembly, and then the verticality of the scraper is measured by turning on a lathe and recording the data, and then the position of the scraper is adjusted. This assembly method is not easy to ensure the verticality and diameter dimensions at the same time. It not only has a large assembly difficulty, requires high equipment requirements, but also takes a long time. Eventually, it is also very difficult to ensure the consistency and accuracy of the dimensions, thus affecting the stability of the equipment. Therefore, by optimizing the assembly process and improving the assembly accuracy, the equipment downtime can be shortened and the production efficiency can be improved. Content of the Utility Model
