Layered-pulverizing beater for paper making

Abstract

The invention discloses a layered-pulverizing beater for paper making. The beater comprises a housing, a motor, a feeding hopper, a rotary shaft, beating blades and a rotary tube, the rotary tube is coaxially and vertically fixed to the rotary shaft arranged below the beating blades, multiple horizontal layering plates are uniformly distributed from top to bottom of the outer side wall of the rotary tube, the upper and lower portions of the layering plates are provided with a plurality of fixing rods which are fixed to the inner wall of the housing, a plurality of beating teeth are fixed to the side walls of the fixing rods, squeezing strips are fixed to the corresponding layering plates located between the adjacent beating teeth, and water spraying holes are formed in the parts located onthe side wall of the rotary tube corresponding to the upper layers of the layering plates. By arranging the rotary tube to drive the layering plates on the outer side of the rotary tube to rotate andmatching with the beating teeth and the squeezing strips to perform pulverizing, raw materials are allowed to be pulverized by the beating teeth and the squeezing strips for multiple times when the raw materials flow downwards, the beating efficiency is improved, and the processing time is shortened.

Description

technical field [0001] The invention relates to papermaking equipment, in particular to a papermaking beater for layered pulverization. Background technique [0002] Modern papermaking procedures can be divided into steps such as pulping, modulation, papermaking, and processing. Pulping is the first step in papermaking, and its purpose is to convert wood into pulp. The general papermaking pulp preparation process can be roughly divided into loose pulp and beating. , adding glue and filling, among them, beating is generally carried out by using a special beater, the structure of the currently commonly used beater is complex, the work efficiency is low, and a lot of time is wasted by prolonging the working time to meet the beating requirements; in addition, the existing beating The machine only works through the single work of the beating blade, and it is easy to form a crushing dead angle inside, resulting in still large pieces of raw materials inside after beating, making th...
