A single-screw refiner

Abstract

The invention relates to a pin barrel single-screw refiner. According to the pin barrel single-screw refiner, a motor drives a threaded rod to rotate after a speed reducer reduces the speed, the threaded rod is arranged in a cylindrical barrel with a radial pin, and a feeding port performing feeding tangentially is formed in the front end of the threaded rod; a fiber raw material is forcibly put into the refiner through a spiral propeller, and under the squeezing action of the threaded rod, the fiber raw material passes through a feeding area of the threaded rod, a plurality of squeezing and cutting areas and is discharged from a discharging area of the tail section of the threaded rod; in a refining process, a main cutting pin set is combined with a plurality of impellers to form a main cutting element respectively, an auxiliary cutting pin set is combined with a transport spiral notch to form an auxiliary cutting element, then the squeezing and cutting functions are applied on a material, so that the fiber raw material is processed into required pulp step by step. The pin barrel single-screw refiner has the advantages of simple structure, lower manufacturing cost, reduced no-loadpower consumption, and convenient use and maintenance.

Description

technical field [0001] The invention belongs to the field of pulp and papermaking, and relates to a refiner for plant fiber raw material production, in particular to a single-screw refiner. Background technique [0002] Refining and beating machinery is the key equipment of pulp and paper making enterprises, and it is also the mechanical equipment with high energy consumption. Since the working principles of pulping and beating machines are basically the same, but the adjustment requirements of working parameters are different, so this type of equipment can be collectively referred to as a refiner, and a refiner specially used for beating is also called a beater. [0003] At present, commonly used pulping and beating machines can be divided into disc, conical and cylindrical refiners according to the shape of their rotors. Disc refiners (referred to as disc refiners) are mainly divided into single disc refiners, double disc refiners and triple disc refiners, and conical ref...

Problems solved by technology

Its characteristic is that the convex-concave array on the inner wall of the barrel is difficult to process. If the convex-concave array is too small, it is easy to be worn and the service life is short; if the array is too large, it is difficult to ensure the quality of refining; therefore, this patent has not been popularized.
