Problems solved by technology

However, in the process of stirring and pumping in the slurry tank, due to the shearing effect, its retention effect will be greatly weakened
Moreover, similar limitations occur with many other additives
[0004] The existing additive adding unit controls the additive adding unit by using the control unit to realize intermittent additive adding, but the additive added to the grouting pipeline has poor dispersibility, and the additive does not mix well with the slurry in the grouting pipeline. Uniformity, which seriously affects the output quality and production efficiency of pulp molded products

Abstract

The invention provides an adding device of a paper pulp moulding assistant, comprising a storing unit for storing an assistant, an adding unit for adding the assistant, an input pipe for connecting the storing unit with the adding unit, an output pipe connected with the adding unit, a control unit for controlling the adding unit, an assistant dispersing pipe for evenly dispersing the assistant ina pulp injecting pipe and a stirring and blending unit for evenly mixing the assistant with pulp in the pulp injecting pipe. The intermittent adding of the assistant in the pulp is realized by regulating the pressure and the air quantity of a pneumatic unit in the invention; the assistant is evenly dispersed in the pulp injecting pipe by the assistant dispersing pipe; the assistant and the pulp in the pulp injecting pipe are evenly mixed by the stirring and the mixing of the stirring and blending unit, so that the uniformity and the adding efficiency of the assistant for paper pulp moulding are largely improved; the dispersing failure of the assistant for a long time is effectively prevented; and the invention has important significance on the improvement of the quality and the productivity of paper pulp moulding products.

Description

technical field [0001] The invention relates to a device for adding pulp molding aids. Background technique [0002] With the development of the economy, people's awareness of environmental protection has gradually increased, and new environmentally friendly biodegradable composite materials have attracted more and more attention and developed rapidly. The raw materials for pulp molding are mainly non-wood fiber raw materials such as bamboo pulp, wheat straw pulp, bagasse pulp, and waste paper. Social value. Due to the characteristics of non-polluting and recyclable plant fibers, paper materials have broader application potential in many fields. [0003] Pulp molding uses non-wood fiber raw materials or low-end fiber raw materials such as waste paper raw materials. Pulp molding additives are an important way to improve its performance and play a pivotal role in the pulp molding industry. Especially with the gradual expansion of the application field of pulp molding produc...
