Embodiment 1

[0063] This example provides a method for processing and reusing the backflow glue from the sizing machine, please refer to figure 1 , the processing reuse method includes the following steps:

[0064] S1. Acquiring the reflowed total rubber material; the reflowed total rubber material includes the recycled surface layer rubber material and the recycled bottom layer rubber material;

[0065] S2, carrying out slag removal treatment on the reflowed total rubber material;

[0066] S3. According to the preset amount of glue on the surface layer and the amount of glue on the bottom layer, calculate the amount of backflow glue on the surface layer and the amount of backflow glue on the bottom layer; distribute the total backflow glue after the slag removal treatment according to the calculation results, and obtain Surface reflow compound and bottom reflow compound;

[0067] S4. Supplement fresh rubber material for the surface layer into the backflow rubber material of the surface ...

Embodiment 2

[0096] This embodiment provides a system for processing and recycling glue returned from a sizing machine, which is used to realize the processing and recycling method described in Embodiment 1. Please refer to figure 2 , the processing reuse system includes:

[0097] The rubber material recovery module 1 is used to obtain the total backflow rubber material, and the total backflow rubber material includes the recycled surface layer rubber material and the recycled bottom layer rubber material;

[0098] The rubber material slag removal module 2 is used to remove the slag treatment on the reflowed total rubber material;

[0099] The rubber material distribution module 3 is used to calculate the amount of backflow rubber material on the surface layer and the back flow rubber material amount on the bottom layer according to the preset amount of glue material on the surface layer and the bottom layer, and calculate the total amount of backflow material after the slag removal treatm...

Abstract

The invention discloses a method and a system for processing and recycling backflow glue from a sizing machine. The method includes the following steps: obtaining the total backflow glue; Slag material; carry out slag removal treatment on the total refluxed sizing material; calculate the amount of sizing material on the surface layer and the sizing material on the bottom layer according to the preset amount of sizing material on the surface layer and the sizing material on the bottom layer; The processed backflow total rubber is distributed to obtain surface layer backflow rubber and bottom backflow rubber; add fresh surface layer rubber to the surface layer backflow rubber to obtain surface topping rubber; add backflow rubber to the bottom layer Fresh sizing material for the bottom layer to obtain sizing material for the bottom layer. According to the difference in the amount of sizing material on the surface layer and the amount of sizing material on the bottom layer, the present invention reasonably distributes the recycled total sizing material, and can independently control the performance parameters of the sizing material on the surface layer and the sizing material on the bottom layer to meet the actual production requirements. Requirements for different indicators on the front and back of paper types.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a method and system for processing and recycling glue returned from a sizer. Background technique [0002] The surface and bottom return sizing materials of conventional immersion sizing machines cannot be separated, and are directly returned to the sizing system for reuse after unified purification treatment. Negative indicator requirements. Contents of the invention [0003] The object of the present invention is to provide a method and system for processing and recycling the backflow glue from a glue sizing machine, so as to solve the above problems. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A method for processing and reusing sizing machine backflow sizing material, comprising the following steps: [0006] Obtaining the total sizing material of return flow; the total sizing material of the return flow includes the siz...
