Abstract

The invention relates to an automatic frequency conversion pulping system in a household paper manufacturing process. The automatic frequency conversion pulping system comprises field equipment, system control hardware, control program software and a running program; the field equipment is connected with the system control hardware; the system control hardware is controlled by the control program software and the running program to run; and the field equipment comprises equipment in a water adding process, equipment in a material charging process, equipment in a pulping process and equipment in a pulp pumping process. The newly designed system is an energy-saving operation system based on automatic operation, and can effectively overcome the defects that high difficulty in controlling technological parameters, high labor intensity of an operator, waste of energy sources and the like caused by a low automatic program, and the complex control processes are realized by a programmable logic controller (PLC), so that operation difficulty is simplified and automation degree is improved.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an automatic frequency conversion pulping system in the production process of household paper. Background technique [0002] The process of shredding and pulping in the tissue paper manufacturing process is based on the manual operation process, the degree of automation is not high, and the process parameters vary from person to person. The amount of water added is to use a fixed water pressure to maintain a stable flow, and a timer is used to calculate the amount of water added. This water addition unit is simple but the measurement is cumbersome and the accuracy is low. The pulping motor adopts a common motor, and the disadvantage of using a common motor as a power source is that the waste of energy is large, and the impact on the rotor is large when the pulp is fed. In terms of electrical control, the design is based on the manual control of each control unit. The disadvantages ...
