Dewatering device for paper making

Abstract

The invention discloses a dewatering device for paper making. The device includes a support, a driven water absorbing roller group is arranged above the support, and the outer side of the circumference of each driven water absorbing roller is wrapped with a water absorbing material layer; a press roller is arranged at the lower side of the driven water absorbing roller group, and the driven water absorbing roller group is mutually squeezed with the press roller; the interior of the press roller is provided with a pressing boot, a boot beam is arranged below the pressing boot, and the upper end of the boot beam abuts against the lower end of the pressing boot to support the pressing boot; a boot sleeve is arranged on the periphery of the pressing boot in a wrapping mode, and a water absorbing layer and a plastic layer are arranged on the surface of the outer circumference of the press roller successively from inside to outside; the interior of the plastic layer is provided with a micro circular hole, a driving water absorbing roller group is arranged below the press roller, and a servo numerical control motor is arranged on the left side of a driving water absorbing roller shaft. The dewatering device for paper making is simple in structure, can effectively remove moisture in wet paper pages, and greatly reduces production energy consumption.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a dewatering device for papermaking. Background technique [0002] With the development of society and the improvement of people's living standards, the market has put forward higher and higher requirements for the quality of paper. In the papermaking industry, the paper sheet still contains a lot of moisture after it is formed in the wire section, and it enters the drying section of the dryer. Before drying, the formed wet paper sheet needs to be further dehydrated by pressing through the pressing section, so that the wet paper sheet is not easily broken and cracked when entering the drying section of the dryer, and the dehydrated wet paper sheet is further pressed by the pressing section. Entering the drying section of the drying cylinder can save the heat of the drying section of the drying cylinder and improve the drying efficiency of the paper sheet. If it is d...

[0002] With the development of society and the improvement of people's living standards, the market has put forward higher and higher requirements for the quality of paper. In the paper industry, paper still contains a large amount of water after it is formed in the wire section. Before drying, the formed wet paper needs to be further dehydrated by pressing through the press section, so that the wet paper is not easy to break and crack when it enters the drying section of the dryer, and the dehydrated wet paper is further pressed by the press section Entering the drying section of the drying cylinder can save the heat of the drying section of the drying cylinder and improve the drying efficiency of the paper sheet. If it is directly sent to the drying without pre-dehydration, a large amount of steam will be consumed, and the resulting
