Intelligent papermaking machine partitioned steam humidifying device

Abstract

The invention discloses an intelligent papermaking machine partitioned steam humidifying device, which belongs to the technical field of papermaking machines and comprises a rack, an upper steam box is mounted on the rack, one side of the rack is hinged to one side of a lower steam box, the bottom of the other side of the lower steam box is hinged to a push rod of a cylinder, and the cylinder is hinged to the bottom of the rack. Coil pipes and steam spraying assemblies are installed in the upper steam box and the lower steam box, a steam cabinet is arranged on the outer side of the rack, the input end of the steam cabinet is connected with one ends of the coil pipes through preheating steam outlet pipes, the other ends of the coil pipes are connected with a pressure reducing device through preheating steam inlet pipes, and the output end of the steam cabinet is connected with the steam spraying assemblies through dry steam inlet pipes. The coil pipes carry out preheating and heat preservation on the upper steam box and the lower steam box through steam, condensate water is prevented from dropping on paper, the preheated steam flows into the steam cabinet through the preheating steam outlet pipes, the steam cabinet carries out flow dividing and drying on the steam, dry steam is provided for the steam spraying assemblies in the upper steam box and the lower steam box, . the steam spraying assembly evenly sprays steam to the two faces of the paper for humidification.

Description

technical field [0001] The invention relates to the technical field of paper machines, in particular to an intelligent paper machine partition steam humidifier. Background technique [0002] As an effective means of adjusting and improving the smoothness and gloss of finished paper, steam humidifiers have been widely used in high-demand paper production lines such as newsprint, glassine paper, and copy paper since the 1980s; humidifiers are installed on paper Before the calender of the machine, it can effectively improve the moisture distribution of the paper banner, improve the consistency of the smoothness of the paper after calendering, and improve the product quality. The current steam humidification device is directly wrapped on the paper by two paint spray boxes. The factory steam is sprayed on both sides of the paper, the steam is not effectively controlled by pressure and temperature, the paper is not evenly humidified, and the steam sprayed on the paper is likely to...

[0002] As an effective means of adjusting and improving the smoothness and gloss of finished paper, steam humidifiers have been widely used in high-demand paper production lines such as newsprint, glassine paper, and copy paper since the 1980s; humidifiers are installed on paper Before the calender of the machine, it can effectively improve the moisture distribution of the paper banner, improve the consistency of the smoothness of the paper after calendering, and improve the product quality. The current steam humidification device is directly wrapped in the paper by two paint spray boxes. On both sides of the paper, the factory steam is sprayed on the paper. The steam is not effectively controlled by pressure and temperature, and the paper is not evenly humidified, and the steam sprayed on the paper is likely to produce condensed water due to the difference in the external environment temperature. When the condensed water drips on the paper, it will form Paper disease affects the quality of paper, and the installation of the steam box has low positioning accuracy, it is difficult to quickly put the paper between the steam boxes, and the operation is inconvenient
