Vertical pulping kettle

Abstract

The invention discloses a vertical pulping kettle, which comprises a kettle body, wherein a kettle cover is arranged above the kettle body, the lower end of a first coupling sleeve is fixed at the topof the kettle cover, the top of the first coupling sleeve is fixedly connected with a motor, the outer side of a motor driving shaft is sleeved with a second coupling sleeve, a bearing box is fixedlyarranged in the first coupling sleeve, a stirring shaft is arranged in the kettle body in the vertical direction, one end of the stirring shaft sequentially penetrates through the kettle cover and the bottom of the bearing box and is in driving connection with the second coupling sleeve, a self-aligning bearing is mounted on the outer side of the joint of the stirring shaft and the second coupling sleeve, the self-aligning bearing is arranged in an upper bearing seat, the upper bearing seat is fixed on the inner side wall of the bearing box through an upper sealing seat, the upper bearing seat, the upper sealing seat, the stirring shaft and the bottom of the bearing box form a bearing oil tank, a bearing is arranged at the joint of the bottom of the bearing box and the stirring shaft andarranged in a lower bearing seat, and the lower bearing seat is fixed outside the bottom of the bearing box through a lower sealing seat. The vertical pulping kettle has the advantages of stability inoperation, no wall hanging, no material accumulation, long service life, easiness in maintenance and the like.

Description

technical field [0001] The invention relates to the technical field of pulping equipment, in particular to a vertical pulping kettle. Background technique [0002] With the continuous development of society, my country's pulping industry is developing rapidly, the market share of pulping equipment is constantly expanding, and people's demand for pulping equipment is becoming increasingly urgent. Most of the existing pulping equipment is pulping with ordinary stirred tanks. The internal structure design and manufacture of these stirred tanks are relatively simple, and there are the following defects in the use process: (1) the existing pulping equipment is due to stirring The shaft is only equipped with a single fulcrum bearing for support, the runout of the stirring shaft is not easy to control, it is easy to shake during work, and the stability of the equipment is not good; (2) There is no lubricating oil in the installation chamber of the bearing, and the bearing is under ...
