Problems solved by technology

[0003] Papermaking is one of the four great inventions of our country. It has a long history. At present, the wet papermaking process is widely used in our country, but its production process requires a lot of water resources, and requires a lot of investment in environmental protection facilities and operating costs. Due to the large consumption of water resources and serious environmental pollution, it is no longer in line with the current development trend of science and technology for energy conservation and emission reduction; and although the dry-laid papermaking also has a certain scale, the quality of the paper it produces is lacking, and all papermaking has not yet been realized. Desired performance and quality requirements

Abstract

The invention discloses a dry papermaking device which comprises a material preparation device, a forming device, a transferring net, a compacting roller and a drying box, wherein the material preparation device, the forming device, the transferring net, the compacting roller and the drying box are connected in sequence; the forming device comprises a pulp distributor, a pulp flow box and a vacuum net cage; the pulp distributor comprises a pulp distributor body, a Venturi pipeline and a pulp distributor inlet pipe; the material preparation device is connected with the lower end of the pulp distributor body through the pulp distributor inlet pipe and the Venturi pipeline; the upper end of the pulp distributor body is connected with one end of the pulp flow box; the other end of the pulp flow box is arranged on the outer side of an inlet of the vacuum net cage; the outlet end of the vacuum net cage is connected with the transferring net; the vacuum net cage is driven by a variable-speed motor. The dry papermaking method based on the equipment comprises the following steps: material preparation, forming, transferring, compacting, drying and coiling; made paper has the advantages of surface fineness, softness, comfortableness and zero linting and dusting; furthermore, no glue is applied in the papermaking process, so that a large amount of water resources can be saved; therefore, the dry papermaking device and the dry papermaking method are environment-friendly and energy-saving.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a dry-process papermaking device and method. Background technique [0002] Paper is an important resource in human social life. No matter reading, reading newspapers, writing, painting, or daily life, paper is in contact with it. In industry, agriculture and defense industry, paper is also inseparable. Today, if there is no paper , that is simply unimaginable. [0003] Papermaking is one of the four great inventions of our country. It has a long history. At present, the wet papermaking process is widely used in our country, but its production process requires a lot of water resources, and requires a lot of investment in environmental protection facilities and operating costs. Due to the large consumption of water resources and serious environmental pollution, it is no longer in line with the current development trend of science and technology for energy conservat...
