Abstract

The invention discloses a conical refiner with mechanical and hydraulic linkage for adjusting tool feeding and retracting and refining pulp specific pressure, the conical refiner comprises a conical refiner body and a mechanical and hydraulic linkage adjusting unit, wherein the conical refiner body comprises a base, a main shaft, a conical refiner main body, a bearing body base and a main motor, the conical refiner main body, the bearing body base and the main motor are sequentially fixed on the base; the mechanical and hydraulic linkage adjusting unit comprises a mechanical adjusting unit anda hydraulic adjusting unit, the hydraulic adjusting unit comprises a motor, a hydraulic pump, a pressure regulating valve, an electromagnetic direction valve, a pressure maintaining valve, an oil filter, an oil tank and a hydraulic cylinder; and the mechanical adjusting unit comprises a handwheel fine adjustment nut. The hydraulic cylinder comprises a cylinder body, a piston with a central hole,a piston rod sleeve and a pressure gauge. According to the invention, the tool feeding and retracting of a conical rotor and refining pulp clearance and refining pulp specific pressure between the conical rotor and a conical stator can be adjusted through a mechanical and hydraulic linkage adjusting loop, the grinding of biomass and the refining of plant fiber are realized, the refining pulp quality and the refining pulp efficiency are improved, and the refining pulp energy consumption is reduced.

Description

Technical field [0001] The invention belongs to the field of biomass waste resource utilization and plant fiber pulping, and relates to biomass refining, pulping and paper-making fiber refining equipment, in particular to a machine-liquid linkage adjustment of advance, retreat and refining specific pressure. Shape refiner. Background technique [0002] my country’s pulping and papermaking raw materials are in short supply. Following the 2017 Ministry of Environmental Protection issued the "Environmental Protection Management Regulations on Imported Waste Paper" and the "Environmental Protection Management Regulations on Restricted Imports of Solid Waste Used as Raw Materials" to regulate imported waste paper and reduce imports Environmental pollution pressure caused by waste paper. In 2017, the approved import of waste paper reached 21.6667 million tons, and the total annual demand for secondary packaging from consumer products reached 50 million tons of corrugated cardboard. The...
