Embodiment Construction

[0020] 1. Dry material preparation, grass cutting and dust removal:

[0021] The grape branches cut off in the year purchased from the grape plantation are used, and they are piled up in the returning material yard for use. Before entering the lawn mower, spread it on the return yard and drive it to flatten. The purpose is to make it easy to cut after flattening. The flattened grape branches are transported to the lawn cutter and cut into 15-30mm long pieces with a water content of 25-35%. After being dedusted by the dust collector, they are transported to the screw conveyor by the scraper conveyor for pre-soaking, and then Load 40m by hand with a pot loader 3 steamed balls.

[0022] 2. Batch cooking, black liquor pre-extraction:

[0023] After the dry preparation process, the grape branch material is mixed with the cooking liquid, then passed through the spiral prepreg machine, the pot loader, and then put into the steaming ball for cooking. The cooked coarse pulp is spra...

Abstract

A process method for using grape branches as raw materials to manufacture pulp of natural-color paper for daily use mainly comprises two portions of cooking and screening and washing, wherein a cooking method comprises the steps of dry-method material preparation, chaff cutting and dust removal, intermittent cooking by means of a rotary spherical digester, coarse pulp spraying and black liquid pre-extraction, and a screening and washing process comprises the steps of coarse pulp roughing, countercurrent washing, closed screening, secondary purification, screening and washing and re-washing by means of a pulp washer. The method is characterized in that the grape branches are used as the raw materials in the dry-method material preparation, firstly rolled by using a vehicle and then are cut into 15-30 mm material pieces by a chaff cutter, and the moisture of the material pieces is 15-25%. The method utilizes the grape branches as the raw materials to turn waste into treasure, make pulp and manufacture natural-color paper for daily use. Compared with existing produced corrugated paper, the grade and level of paper are greatly improved, production working procedures of the natural-color paper for daily use do not include a bleaching working procedure, manpower and material resources and production cost are saved, and meanwhile harm to human body health of a process for producing bleached paper for daily use is decreased.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for producing uncolored household paper pulp using grape branches as raw materials. Background technique [0002] Grape branches contain good fibers and are suitable for papermaking. Making full use of grape branches to produce natural pulp for daily use will fundamentally solve the current problems that grape branches are difficult to handle, affect the environment, and restrict the development of the grape industry. Picking—grape wine—grape pruning to make paper” is a circular economic cultural model for the grape industry. Grape branches grow fast and have a short cycle. The average diameter of one-year-old grapes can reach about 1cm, and the length is more than 2-4m. Generally, they are stubbled once a year, and new branches will be reissued in the second year. Chinese patent discloses "a kind of grape pulp" (patent application number: CN201110426989.9). Realiz...
