Abstract

A PLC-based paper pulp water absorption control system comprises a PLC, a liquid crystal touch screen, a motor actuator, a vacuum pump, a filtrate pump, a white water pool, a vacuum pump motor, a filtrate pump motor, a wire section vacuum water absorption tank, a vacuum couch roll, an upper coarse cotton cloth vacuum water absorption tank, a lower coarse cotton cloth vacuum water absorption tank, a header pipe and a front-mounted gas-water separator. Suction and discharge of water in paper pulp are controlled through the touch screen and the PLC, the vacuum pump can be controlled by the PLC to adjust the rotating speed of the vacuum pump motor in real time according to sucking rate required by a certain vacuum degree, the rotating speed of the vacuum pump can be reduced by the PLC when the redundant amount of the vacuum pump is far larger than what is required by production technology, and then energy is saved and operation reliability is improved. The system has the advantages of being reliable in performance, capable of saving energy, easy to control and high in control precision and the like, and has high popularization and demonstration value; furthermore, software flexibility can facilitate transformation and upgrading of equipment.

Description

technical field [0001] The invention relates to the field of electromechanical equipment control, in particular to a PLC-based pulp water absorption control system. Background technique [0002] The paper industry is one of the important basic raw material industries of the national economy, and the consumption level of paper and cardboard has become an important symbol to measure a country's modernization level and civilization level. The paper industry has the characteristics of capital-intensive technology and significant scale benefits. Its industry has a high degree of correlation, and its large market capacity and development potential have become a driving force for the development of forestry, agriculture, machinery manufacturing, chemical industry, automatic control, printing, packaging, and environmental protection. An important force to form a new growth point for the development of my country's national economy. [0003] The paper industry uses native plant fiber...
