Description

TECHNICAL FIELD

[0001] The utility model relates to a drying device for paper production. BACKGROUND

[0002] Paper drying technology is a key link in the production process of paper products. In the paper manufacturing process, after the paper pulp goes through a plurality of processes such as forming and pressing, it contains a large amount of water, which needs to be dehydrated and solidified through a drying device to meet the quality standards of the final product. The drying process not only affects the physical properties of the paper (such as strength, flatness, smoothness, etc.), but also directly relates to production efficiency, energy consumption, and product quality stability. Therefore, the development and optimization of drying technology are of great significance to the paper product industry.

[0003] The existing paper drying equipment has the problem of insufficient flatness of the dried paper, which makes it inconvenient for subsequent transportation, stacking, collection, and other steps. Therefore, a drying device for paper production is proposed to improve the flatness of the dried paper. SUMMARY

[0004] The utility model aims at the deficiency of prior art, and provides a drying device for paper production, which can well solve the above problems.

[0005] The utility model discloses a drying device for paper production which comprises a main drying cavity and a preheating cavity arranged at the front end of the main drying cavity.

[0006] Preferably, the annular heating sheet outside the preheating roller is matched with the arc-shaped air-permeable plate.

[0007] Preferably, the first arc-shaped heating and ironing component and the second arc-shaped heating and ironing component are matched with the first ironing roller and the second ironing roller respectively.

[0008] Preferably, the infeed guide roller and the outfeed guide roller are connected with the inner side wall of the main drying cavity through the support arranged in the main drying cavity.

[0009] Preferably, the top of the first arc-shaped air guide plate is at the same height as the top of the first drying heating plate, the bottom of the first arc-shaped air guide plate is at the same height as the top of the fourth drying heating plate, the top of the second arc-shaped air guide plate is at the same height as the top of the second drying heating plate, and the bottom of the second arc-shaped air guide plate is at the same height as the top of the third drying heating plate.

[0010] The paper production drying device has the following advantages:

[0011] The device first preheats the paper through the arc-shaped air guide plate and the preheating roller, then heats and flattens the paper using the first arc-shaped heating and flattening component and the first flattening roller, then concentrates drying on both sides of the paper using the first drying heating plate, the second drying heating plate, the upper arc-shaped air guide plate, the upper lifting motor, the rear roller, the third drying heating plate, the lower lifting motor, the fourth drying heating plate, and the lower arc-shaped air guide plate, and finally flattens the paper after drying using the second arc-shaped heating and flattening component and the second flattening roller, thereby ensuring that the paper has good flatness after drying.
