Abstract

The invention discloses a novel slurry refining and concentrating system. The novel slurry refining and concentrating system structurally comprises a slurry concentrator, a feeding pipe, a supportingframe, a discharging pipe, a slag discharging pipe and a bearing seat, the slurry concentrator is composed of a machine body, a spraying device, a concentrating mechanism, a driving motor set, a slurry transferring cavity, a stirring mechanism and a slurry guide hole. The slurry concentrator utilizes the spraying device to clean and blend raw materials; the stirring mechanism is used for stirringthe raw materials into fluff pulp; the concentrating mechanism is used for refining and concentrating the fluff pulp; the bonding density of the fluff pulp is improved; so that the fluff pulp is not easy to fall off, a hollow shaft uses a filter disc to filter and discharge the fluff pulp, the fluff pulp product prepared through the technology has the advantages of being high in dry bulkiness, good in absorptivity and moderate in fiber bonding strength, the performance requirement of subsequent fluff pulp for producing disposable hygienic products is met, and the quality defect of the fluff pulp product is overcome.

Description

technical field [0001] The invention relates to the field of thickening sanitary napkins, in particular to a novel slurry refining and thickening system. Background technique [0002] As a water-absorbent material for disposable hygiene products, fluff pulp is filled in the core layer of the cushion, which is in the form of cotton wool, and has the characteristics of high bulkiness and high water absorption. When in use, it is necessary to dry-dissociate the fluff pulp board to obtain fluff pulp fibers. Therefore, suitable bonding strength between fibers and good absorbency of fibers are issues that need to be considered in the fluff pulp preparation process. In the existing research, the raw materials of fluff pulp are mainly made of hardwood, bamboo or cotton linters, etc., and BCTMP, CTMP or CMP pulping methods are used, and chemical pulping is also used, but the fluff pulp fibers produced Short, dry fiber with low bulkiness, poor water absorption, poor filling, and easy...
