Embodiment Construction
[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0031] Please also refer to Figure 1 to Figure 5 Now, the paper machine aging device provided by the embodiment of the present invention will be described. A paper machine maturing device, comprising: a hot air unit 1, a maturing unit 2, and a master control valve 3 which are sequentially connected in circulation. The hot air unit 1 is used to provide hot air for the curing unit 2 . The curing unit 2 is provided with a passing gap 24 and hot air is sent through the gap 24 . The master control valve 3 controls the amount of hot air flowing out of the curing unit...

The invention provides a paper machine curing device and a papermaking production line, and belongs to the field of papermaking equipment. The paper machine curing device comprises a hot air unit, a curing unit and a main control valve which are sequentially and circularly communicated. The hot-air unit is used for providing hot air for the curing unit. The curing unit is provided with a passing gap and sends hot air into the passing gap. The main control valve controls the hot air outflow amount of the curing unit so as to control the amount of hot air fed into the passing gap by the curing unit. The papermaking production line comprises the paper machine curing device. When the paper machine curing device and the papermaking production line are used, the filter paper penetrates through the passing gap, the amount of hot air fed into the passing gap by the curing unit can be controlled by adjusting the main control valve and controlling the hot air outflow amount of the curing unit, the curing temperature of the filter paper can be rapidly and accurately controlled, and the curing requirement of the novel filter paper can be met.
Description
technical field [0001] The invention belongs to the technical field of papermaking equipment, and more specifically relates to a paper machine aging device and a papermaking production line. Background technique [0002] Ordinary filter papers are generally produced by thermoplastic products such as acrylic acid, acetic propylene, AKD, etc. The filter paper produced by thermoplastic products has the defects of being sensitive to the use temperature and having large stiffness changes, which cannot meet the needs of some special use environments. Require. [0003] With the upgrading of filter paper, a new type of filter paper has appeared. A certain amount of thermosetting chemical products are added to the formula of this new type of filter paper, so that this type of new type of filter paper can be well adapted to various use environments. Good market prospect. However, this type of new filter paper needs to be heated and matured after drying, and the temperature for curin...
