Conversion tank used in production of surface sizing agent

Abstract

The invention discloses a conversion tank used in production of a surface sizing agent. The conversion tank comprises a cavity, a mixer arranged on the top of the cavity, a support arranged at the lower side of the cavity and a force pump installed at one side of the cavity, wherein the output terminal of the force pump is connected with the inner side of the cavity; the input terminal of the force pump is connected with a dissolving tank; the bottom of the cavity is provided with a discharge outlet; the cavity is composed of an inner wall and an outer wall; a steam heating pipeline is arranged between the inner wall and the outer wall; and the steam heating pipeline is connected with a Venturi steam heating mechanism. According to the invention, the Venturi steam heating mechanism is used for guaranteeing uniform heating and maximally reducing steam output noise; the whole operation of the conversion tank is high in automation degree and can completely cooperate with previous-stage operation and output to subsequent-stage operation is perfectly realized, so integral production-line process is formed; and the conversion tank can monitor a conversion environment and conversion time.

Description

technical field [0001] The invention relates to a conversion tank, in particular to a conversion tank for surface sizing agent production, and belongs to the technical field of surface sizing agent production equipment. Background technique [0002] Surface sizing is a process in the process of paper or cardboard processing. It is usually located at the end of the drying section of the paper machine. When the paper is not completely dry but has a certain strength, a layer of glue is sprayed on the paper and paper after subsequent drying. A layer of adhesive film is formed on the surface of the cardboard, so as to achieve the purpose of changing the surface properties of paper or cardboard; from the perspective of the development of the paper industry, paper-making surface sizing is one of the indispensable processes, and the improvement of paper sheets can be greatly improved through surface sizing. A surface additive for performance or to increase the water resistance of pa...

[0002] Surface sizing is a process in the process of paper or cardboard processing. It is usually located at the end of the drying section of the paper machine. When the paper is not completely dry but has a certain strength, a layer of glue is sprayed on the paper and paper after subsequent drying. A layer of adhesive film is formed on the surface of the cardboard, so as to achieve the purpose of changing the surface properties of paper or cardboard; from the perspective of the development of the paper industry, paper-making surface sizing is one of the indispensable processes, and the improvement of paper sheets can be greatly improved through surface sizing. A surface additive for performance or to increase the water resistance of paper or cardboard; the manufacturing process of starch surface sizing generally includes dissolving, transforming, inactivating enzymes, and feeding starch after storage; during the starch conversion process, the dissolved starch is The conversion time and temperature of the existing starch conversion tank are controlled by the experience of the operator, the error is relatively high, and it cannot form an operation pipeline with the previous stage and the subsequent stage.
