Chemical adding device for pulping process

Abstract

The invention relates to a chemical adding device for a pulping process. The device is used for injecting required chemicals into a pulper. The device includes a rack, wherein a dosing mechanism, a telescopic air cylinder, a controller and a dosing barrel are arranged in the rack; the dosing mechanism comprises a shell and a piston; an infusion tube connecting hole is formed in one end of the shell; a through hole is formed in the other end of the shell, the infusion tube connecting hole is connected with a dosing barrel through a liquid pipeline; the liquid conveying pipe connecting hole is connected with the pulper through another liquid pipeline, the controller is connected with the telescopic air cylinder, a connecting rod of the telescopic air cylinder extends into the through hole and then is fixedly connected with a piston, the two liquid pipelines are respectively provided with a one-way valve, scale marks are arranged on the barrel wall of the dosing barrel, and a liquid levelinduction alarm is arranged in the dosing barrel. Compared with the prior art, the device has the advantages of simple operation, accurate metering, time saving, labor saving and the like.

Description

technical field [0001] The present invention relates to the technical field of pulping process equipment, in particular to a chemical adding device for pulping process. Background technique [0002] In the field of soft tissue paper production, the pulping process is an essential step. In the existing pulping process, it is necessary to add pulping enzymes or other chemicals for treatment. The pulping enzyme is a biological enzyme, and the pulping enzyme must be intermittently operated synchronously with the pulping operation during the production process of soft tissue paper. [0003] Due to the particularity of the addition of beating enzymes and other similar chemicals, most of the addition of various types of chemicals can only be done manually at this stage. Repeated manual operations are time-consuming and labor-intensive, with high cost and easy to cause problems such as inaccurate addition. In addition, when manual operation is used, if the chemicals to be added are...

Problems solved by technology

[0003] Due to the particularity of adding beating enzymes and other similar chemicals, most of the addition of various types of chemicals can only be done manually at this stage. Repeated manual operations are time-consuming, costly, and likely to cause problems such as inaccurate addition.

In addition, when using manual operation, if it is found that the chemicals to be added are insufficient during the operation, the operator needs to obtain the raw materials stored in the storage tank to add again, and manual operation is also required, and accurate measurement and observation cannot be done.
