Description

Technical Field

[0001] The utility model belongs to the technical field of dehydration devices, and in particular relates to a dehydration device for producing packaging base paper. Background Art

[0002] Packaging base paper refers to paper that has not been printed or processed or has only undergone preliminary processing (such as coating, impregnation, glazing, lamination, etc.), and is specifically designed for further processing into various packaging containers (such as cartons, paper boxes, paper bags, etc.).

[0003] Dehydration devices achieve solid-liquid separation and material dehydration through different working principles, such as centrifugal force, squeezing pressure, and vacuum pressure. These devices use specific mechanical structures and working media to remove moisture from the material to achieve the desired dehydration effect.

[0004] The authorization publication number "CN206902468U" records "a packaging paper scraper type clamping net dewatering device, comprising a bottom net, wet paper, a top net, a first scraper type dewatering element and a second scraper type dewatering element, the top net is provided on the upper side of the bottom net, wet paper is placed between the bottom net and the top net, both ends of the bottom net and the top net are fixedly installed by locking rollers, the first scraper type dewatering element is installed on the lower side of the bottom net, and the second scraper type dewatering element is installed on the upper side of the top net. The first scraper-type dewatering element and the second scraper-type dewatering element each include a housing, a liquid storage chamber and a scraper chamber are provided inside the housing, and a strip channel is connected to one end of the lower side of the liquid storage chamber and the scraper chamber. This packaging paper scraper-type clamping wire dewatering device, through the bottom wire, top wire, first scraper-type dewatering element and second scraper-type dewatering element, sandwiches the wet paper between the top and bottom wires, achieving double-sided dewatering, higher dehydration efficiency, and more steam-saving drying.

Then, the multiple squeezing drums 3 are caused to rotate unidirectionally to ensure unidirectional dehydration of the wet paper, and then the wet paper is repeatedly dehydrated by the multiple squeezing drums 3, thereby enhancing the dehydration capacity of the production and packaging base paper dehydration device. At the same time, the accumulated water stains are guided into the multiple sponge sleeves 17 through the penetration holes on the circumferential surface of the multiple squeezing drums 3. The multiple sponge sleeves 17 rotate synchronously with the multiple squeezing drums 3. The multiple scraping drums 4 squeeze the multiple sponge sleeves 17 to scrape out the water stains in the multiple sponge sleeves 17, squeeze the wet paper and recover water, thereby reducing the water content in the wet paper, so that when the wet paper is dried, the power consumption of the dryer is reduced, and the waste of water resources and electric energy is avoided.
