Papermaking equipment and papermaking process thereof

Abstract

The invention discloses a papermaking equipment and a papermaking process thereof, comprising: a slurry suction device, a net blanket is provided at the outlet end of the slurry suction device, and turning rollers are arranged at both ends of the net blanket, and above the turning roller A drying cylinder is provided, and a transfer roller is arranged in the drying cylinder. A heat dissipation device is provided on the side of the drying cylinder away from the turning roller, and a forming roller is provided on the side of the heat dissipation device away from the drying cylinder. Pass through turning rollers, transfer rollers, heat dissipation devices, and forming rollers; the heat dissipation device includes a heat-absorbing fan, and the heat-absorbing fan is arranged at the lower part of the heat dissipation device. The present invention is equipped with a cooling device on the outlet side of the drying cylinder. The cooling device absorbs the heat through the heat-absorbing fan and discharges it into the pipeline at the lower end. The filter in the pipeline filters out impurities and then transports the heat to the slurry suction device It is absorbed by the sucked pulp, which increases the temperature of the pulp, reduces the time required for drying the pulp, makes full use of resources, saves energy, and protects the ecological environment.

Description

technical field [0001] The invention relates to the technical field of paper production, in particular to a papermaking equipment and a papermaking process thereof. Background technique [0002] Paper is one of the four great inventions in ancient China. As early as 105 AD, Cai Lun summed up the experience of making paper with hemp fiber since the Western Han Dynasty. After papermaking, it was introduced to Europe, and the papermaking industry was booming all over the world, bringing benefits. At the same time, it also brings very serious pollution. General papermaking equipment produces a lot of waste, which causes serious pollution to the environment. Currently, the papermaking equipment on the market still has the problem of low energy utilization. The heat will be directly emitted into the atmosphere, causing a great waste of resources. [0003] After retrieval, the Chinese patent application number 201610923948.3 discloses a papermaking equipment, including a pulp suct...

AI Technical Summary

Problems solved by technology

One side of the pulp suction device is connected to drive the net blanket, the upper surface of the driven net blanket is connected to the transfer roller, the lower surface of the driven net blanket is connected to the drying cylinder, and one end of the driven net blanket is connected to the profiling device, and the profiling device is The linked circulation system is easy to use, less intrusive, environmentally friendly and at the same time solves the problem of low resource utilization, improves the efficiency of papermaking, is conducive to sustainable development, is safe and reliable, and expands the development space of enterprises; but the The paper coming out of the drying cylinder in the equipment has no cooling device, and the uncooled paper is prone to wrinkles during storage or subsequent processing. At the same time, the heat in the drying cylinder is discharged into the atmosphere, which causes a waste of resources.
