Energy conservation and emission reduction type drying system of gravure workshop

Abstract

The invention relates to an energy conservation and emission reduction type drying system of a gravure workshop. With the system, defects of high energy consumption and heat wasting rate, high temperature and poor environment in operating workshop, and severe potential safety hazard of the existing drying device with low cost as well as the existing large oven after printing has disadvantages of complicated structure and high cost and is not suitable for the field can be overcome. According to the technical scheme, the system comprises a heat source, a heat transport device, and printing material drying devices; and the printing material drying devices are installed at an after-printing stations of gravure equipment. The system is characterized in that the heat source is a steam boiler arranged outside a gravure workshop. The heat transport device consists of a blower, a main steam feeding pipe, a plurality of branch steam feeding pipes, a main steam return pipe, and a plurality of steam return pipes. The printing material drying devices are a plurality of baking rollers that are arranged on the gravure equipment in the gravure workshop in a rotation cooperation mode and are in driving rotation connection with a drive unit; and the diameters of the baking rollers are 60 to 100 cm. The branch steam feeding pipes and the steam return pipes are connected with cavities from one sides of all baking rollers; and steam guiding pipes of steam in-out seats extend into the cavities of the baking rollers.

Description

technical field [0001] The invention relates to post-press drying equipment for paper products used for folk worshiping Buddha, worshiping gods, praying for blessings and offering sacrifices, in particular to an energy-saving and emission-reducing drying system for a gravure printing workshop. It is suitable for continuous conveying operation of printing materials in rolls. Background technique [0002] The paper used for folk worship, god worship, blessing, and sacrificial paper products is generally a paper with coarser fibers and a rougher surface. Printing pictures and texts on this kind of paper requires a thicker ink layer in order to obtain better printing quality. Therefore, the gravure printing method is regarded as the best printing method. However, gravure printing is a kind of fast printing. Due to the fast printing speed, the requirements for the post-press drying device are particularly high. However, the folk paper products for worshiping Buddha, worshiping ...
