A kind of intelligent adding device for papermaking dry strength agent

Abstract

The invention discloses an intelligent adding device for paper-making dry strength agent, which includes a dilution component and a mixing component, the dilution component includes a water storage tank, a water inlet pipe and a temporary storage box, and a temporary storage cavity is arranged in the temporary storage box , the water storage tank is connected to the top outside of the temporary storage tank through a water inlet pipe, and the water inlet pipe communicates with the temporary storage chamber; the mixing assembly includes a housing, a partition arranged in the housing, and the partition Divide the internal space of the housing into a feeding chamber and a mixing chamber, the temporary storage box is fixed on the outside of the housing, a first through pipe is arranged above the inner wall of the temporary storage chamber to communicate with the mixing chamber, and the temporary storage chamber A second through pipe is provided under the inner wall to communicate with the mixing chamber, and a feeding pipe is provided on the top of the housing to communicate with the feeding chamber; a heating element is provided in the device to prevent the dry strength agent from solidifying and blocking, and the stirring column It can speed up the flow rate of the dry strength agent so that it can enter the mixing chamber faster, and the flushing box can fully mix and dilute the dry strength agent and the diluent.

Description

technical field [0001] The invention relates to the technical field of dry strength agents, in particular to an intelligent adding device for papermaking dry strength agents. Background technique [0002] Dry strength agent is an important class of chemicals to increase the strength of paper in the paper industry. Many water-soluble polymers that can form hydrogen bonds with fibers can be used as dry strength agents. The dry strength agent for papermaking can be quickly adsorbed on the pulp fiber, significantly enhancing the bursting strength and folding strength of the paper. In addition, the dry strength agent for papermaking also has the function of aiding retention and drainage, which can reduce the loss of fine fibers during the papermaking process. Papermaking dry strength agent is widely used, especially suitable for cardboard, cardboard, cultural paper, corrugated paper, etc. [0003] The dry strength agent is usually diluted with water and then added to the slurry....

AI Technical Summary

Problems solved by technology

[0003] The dry strength agent is usually diluted with water and then added to the slurry. There are still many deficiencies in the existing intelligent adding device for paper dry strength agent. First, when the external temperature is low, the dry strength The flow of the agent slows down or solidifies, which affects the addition of the desiccant; secondly, after the dry strength agent is mixed into the slurry, it is difficult to mix fully in a short time
