Problems solved by technology
[0003] However, when using the press section to dry the paper sheets in the prior art, basically only steam is used to dry the paper sheet, so the steam consumption of the press section of the prior art is large.
In addition, the papermaking press section in the prior art also has the disadvantage that the dryness of the paper sheet is not ideal

The invention relates to the technical field of papermaking, in particular to a blind hole pressing part for papermaking. The blind hole pressing part comprises an upper blind hole pressing roller and a lower blind hole pressing roller which are used for pressing paper sheets, a suction box arranged between the upper blind hole pressing roller and the lower blind hole pressing roller, a scraper mechanism arranged above the upper blind hole pressing roller, and a water pan arranged on one side of the upper blind hole pressing roller; a first hydraulic mechanism is arranged above the upper blind hole pressing roller; a second hydraulic mechanism is arranged below the lower blind hole pressing roller; the first hydraulic mechanism comprises a first hydraulic driving part and a first suction piece; the first hydraulic driving part drives the first suction piece to press towards the upper blind hole pressing roller and suck water; the second hydraulic mechanism comprises a second hydraulic driving part and a second suction piece; the second hydraulic driving part drives the second suction piece to press towards the lower blind hole pressing roller and suck water. According to the blind hole pressing part for papermaking, the consumption of steam can be reduced, the dryness of the paper sheets can be improved, and the blind hole pressing part has the advantages of saving energy and reducing production cost.
Description
technical field [0001] The present application relates to the technical field of papermaking, in particular to a blind hole press section for papermaking. Background technique [0002] In the production of papermaking, the press section is a key component for sheet drying. The main function of the press section of the paper machine is to dewater and solidify the paper, while improving the performance of the paper, increasing the strength of the wet paper web to improve the drying capacity of the drying section. In the process of drying paper sheets in the press section, a large amount of steam needs to be consumed for drying the paper sheets. [0003] However, when the press section is used to dry the paper sheets in the prior art, since the paper sheet is basically dried only by steam, the steam consumption of the press section of the prior art is large. In addition, the papermaking press section in the prior art also has the disadvantage that the dryness of the paper she...
