Dispersing and spraying system for papermaking dispersing agent

Abstract

The invention discloses a papermaking dispersant dispersing and spraying system which comprises a mixing box body, a mixing cavity is formed in the mixing box body, a spraying mechanism is arranged in the mixing cavity, and the spraying mechanism comprises a sliding box which is slidably connected to the mixing box body and extends into the mixing cavity; by utilizing a connecting rod transmission principle and a gear transmission principle, the papermaking box filled with paper pulp and the sliding box for spraying a dispersing agent are fixed and slide left and right together by utilizing an ingenious reciprocating mechanical structure, and the spraying area and the spraying efficiency of the dispersing agent are increased by utilizing a gear and rack meshing transmission principle and a planetary gear structure; the dispersing agent is automatically supplemented through left-right movement of the sliding box, manpower and material resources are saved, the adding effect of the dispersing agent is guaranteed, moreover, paper pulp in the papermaking box can be turned over after the dispersing agent is added, the contact area of the paper pulp and the dispersing agent is guaranteed, and therefore the effect of the dispersing agent is improved.

Description

technical field [0001] The invention relates to the technical field of stirring and mixing, in particular to a dispersing and spraying system of a papermaking dispersant. Background technique [0002] During the papermaking process, the paper fibers and fillers in the pulp are hydrophobic and tend to flocculate into agglomerates. It is often difficult to produce paper with uniform properties and satisfactory strength. It is necessary to add an auxiliary agent to increase the viscosity of the pulp, so as to facilitate the uniform dispersion of fibers and fillers, so that the paper produced is uniform, smooth, flexible and free of holes, so that the performance of papermaking is stable, and it is not easy to break paper and powder during papermaking. Improve the tensile force and dry and wet strength of paper products and save pulp. Generally, when adding dispersant, it is difficult to ensure that the dispersant and pulp are fully mixed, resulting in great waste. Contents of...
