Papermaking drying device based on air flow transformation

Abstract

The invention relates to a papermaking drying device based on air flow transformation, which comprises a base, wherein a water tank is fixedly mounted on the upper surface of the base; the outer sideof the water tank is sleeved with drying plates; a rotating rod is movably mounted in the middle of the water tank; a turbine blade is fixedly mounted at the lower end of the rotating rod; and a rotating disc is fixedly mounted at the upper end, penetrating through and extending to the outside of the water tank, of the rotating rod. Water droplets dropping from a cover plate can be effectively blocked due to matched use of a sealing housing, a tension spring, a movable plate, a connecting rope, a heat return plate and corrugated strips; the water droplets cannot drop on paper being dried; situations such as an uneven surface of the paper due to dropping of the water droplets on the paper do not occur; the influence of the dropping of the water droplets on a drying rate of the paper is avoided; drying of paper pulp is accelerated indirectly; the production efficiency is improved; and at the same time, the quality of the made paper is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a papermaking drying device based on air flow conversion. Background technique [0002] The paper machine includes three main parts of forming, pressing and drying to complete the process, and is equipped with necessary finishing, coiling and transmission devices, as well as pulp supply, pulp and white water circulation, vacuum, ventilation and exhaust, broken paper Handling and lubrication, automatic control and other auxiliary systems, while the drying part is one of the very important components in the paper machine. [0003] At present, most of the existing drying parts are drying the wet pulp with a drying plate or an electric heating plate, and then making it into paper.

Problems solved by technology

[0003] At present, most of the existing drying parts are drying the wet pulp with a drying plate or an electric heating plate, and then making it into paper. However, in this form, the moisture in the pulp is dried into paper At the time, it is a physical evaporation process, the water in the pulp changes from a liquid state to a gaseous state, and in the process of gradually rising the gaseous water, it will eventually be intercepted by the cover plate, and the temperature of the cover plate is lower than that of the gaseous water vapor. Therefore, when the gaseous water vapor is cold, it will condense into small water droplets on the cover plate, and finally it will fall and drip on the made paper. Since the paper has not been completely dried and formed, dripping on it may cause the The surface of the paper made is uneven, which affects the drying rate of the paper, thus affecting the quality of the paper
