Double-layer efficient energy-saving drying cylinder

Abstract

The invention relates to drying equipment, in particular to a double-layer efficient energy-saving drying cylinder. The double-layer efficient energy-saving drying cylinder comprises a cylinder barrel, a cylinder inner container, an air inlet pipe, an operation-side cylinder cover and a transmission-side cylinder cover. The operation-side cylinder cover and the transmission-side cylinder cover are installed at the two ends of the cylinder barrel respectively. The cylinder inner container is arranged in the cylinder barrel, and the two ends of the cylinder inner container are connected with the operation-side cylinder cover and the transmission-side cylinder cover respectively. An air inlet is formed in the operating-side cylinder cover, a ventilating hole is formed in the cylinder inner container, the air inlet pipe is arranged in the cylinder inner container, and the two ends of the air inlet pipe are communicated with the air inlet and the ventilating hole in the cylinder inner container respectively. The double-layer efficient energy-saving drying cylinder reduces air consumption, saves coal and electricity and reduces production cost.

Description

technical field [0001] The invention relates to drying equipment, in particular to a double-layer high-efficiency and energy-saving drying cylinder. It is suitable for papermaking, starch, printing and dyeing drying industries. Background technique [0002] The drying cylinder is mainly used in the paper industry, and it uses steam to conduct heat through the cylinder to dry the paper. The drying cylinder is a D1 grade pressure vessel, and the inner pressure cylinder is dried by rotating, and the material is gray cast iron. At present, all drying cylinders at home and abroad are single-layer, and there is no fixed water absorption device. The air intake and outlet are on the transmission side, and only a hose is inserted from the air intake part for water absorption. The water absorption effect is not good, such as figure 1 shown. The larger the diameter and length of the drying cylinder, the larger the volume, and the larger the amount of steam used. At the same time, th...

Problems solved by technology

At present, all drying cylinders at home and abroad are single-layer, and there is no fixed water absorption device. The air intake and outlet are on the transmission side, and only a hose is inserted from the air intake part for water absorption. The water absorption effect is not good, such as figure 1 shown

The larger the diameter and length of the drying cylinder, the larger the volume, and the larger the amount of steam used. At the same time, the corresponding amount of coal and electricity is used, resulting in waste of energy, and increased carbon and warm gas emissions. The production company increases the cost, and the product has no competition. force
