Sealing-free combined rotating ceramic paddle paper pulp stirring equipment

Abstract

The invention relates to the technical field of paper making mechanical equipment, and discloses sealing-free combined rotating ceramic paddle paper pulp stirring equipment. The sealing-free combined rotating ceramic paddle paper pulp stirring equipment comprises a base part, a paper pulp stirring pond, a combined rotating mechanism and a motor; as improved, the torque between a rotation driving belt wheel and a rotation driven belt wheel is transmitted by a rotation transmission belt; the torque between the rotation driven belt wheel and a driven rotating shaft is transmitted by a driven shaft lower key; the torque between a central gear and the driven rotating shaft is transmitted by a driven shaft upper key; the central gear and a rotation gear are mutually meshed; the torque between the rotation gear and a rotation paddle shaft is transmitted by a free rotating key; a rotation square shaft is arranged at the lower section of the rotation paddle shaft; the rotation square shaft is provided with stirring paddles; the stirring paddles are positioned above a pulp pond bottom plate. By arranging a revolution transmission belt and a rotation transmission belt at the inner part of the base support, the operation is convenient and safe; a pulp pond central cylinder is arranged in the paper pulp stirring pond, so that a revolution driving belt wheel and the rotation driving belt wheel which are used for power transmission are thoroughly isolated from paper pulp, no corrosion is caused, and sealing is not needed.

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 an equipment for stirring pulp without sealing combined rotating ceramic paddles. 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 devices on...

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
