Combined rotating paddle no-seal paper pulp stirring equipment assembly and use method thereof

Abstract

The invention relates to the technical field of papermaking mechanical equipment, in particular to combined rotating paddle no-seal paper pulp stirring equipment assembly and a use method thereof. The equipment comprises a base part, a paper pulp stirring pool, a combined rotating mechanism and an electric motor. The equipment assembly comprises the following steps that the electric motor and an active rotating shaft are installed; a combined rotating mechanism and accessories of the combined rotating mechanism are installed; the combined rotating mechanism, the paper pulp stirring pool and the base part are partially assembled; an output shaft of the electric motor drives the active rotating shaft to rotate through a rigid shaft coupler; the active rotating shaft respectively transfers torque to a revolution active belt wheel and an autoroatation active belt wheel through a main shaft revolution key and a main shaft autoroatation key; the combined rotating mechanism integrally does rotating movement around an axial line formed between a driven lower bearing seat and a pulp pool positioning hole; under the combined force effect of autoroatation movement and revolution movement, a stirring paddle performs uniform stirring and mixing treatment on paper pulp above a pulp pool bottom plate; no stirring dead corners are left; the stirring efficiency is improved; the work energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of papermaking machinery and equipment, and the international patent classification number is D21G9 / 00, in particular to the assembly and use method of combined rotating paddle non-sealed stirring pulp equipment. Background technique [0002] Pulp is a fibrous substance made from plant fibers through different processing methods. According to the processing method, it can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp; it can also be divided into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc. according to the fiber raw materials used. According to different purity, it can be divided into refined pulp, bleached pulp, unbleached pulp, high-yield pulp, semi-chemical pulp, etc. Pulp needs to be mechanically processed during the preparation process, and a pulp stirring device is needed to uniformly stir it. However, most of the pulp stirring ...

AI Technical Summary

Problems solved by technology

Pulp needs to be mechanically processed during the preparation process, and a pulp stirring device is needed to uniformly stir it. However, most of the pulp stirring devices on the market have the disadvantages of relatively single structure and low stirring efficiency. For example, the Chinese application number is CN200610068826.7. A medium-consistency pulp tower is proposed, and a medium-consistency pulp tower that saves energy, mixes pulp evenly, and discharges quickly is proposed. The height of the stirring blades in this invention is fixed, which easily causes pulp to deposit at the bottom of the stirring tank. Not only wasting resources, but the long-term deposition at the bottom of the mixing tank also affects the service life of the mixing tank; in addition, there is a certain acidity and alkalinity during pulp processing, and the rotating shaft of the stirring blade of this invention is in direct contact with the pulp, which brings double sealing and corrosion. difficulty

The dilemma technical bottleneck in this field is: if the power transmission mechanism is set above the stirring tank in order to avoid the double difficulty of sealing and corrosion, it will be inconvenient and unsafe for workers to operate, and the single-axis rotation stirring is not uniform, which is easy to leave There is a stirring dead angle
