Horizontal reaction kettle and shaft sealing device for horizontal reaction kettle

Abstract

The invention provides a horizontal reaction kettle and a shaft sealing device for the horizontal reaction kettle. The shaft sealing device for the horizontal reaction kettle solves the technical problem that the shaft sealing device of the existing horizontal reaction kettle has a relatively poor sealing effect. The shaft sealing device is provided with a shaft head, wherein a shaft sleeve is fixedly arranged on the shaft head in a sleeving manner; a supporting seat is arranged outside the shaft sleeve in a sleeving manner; a sealing structure component is arranged between the shaft sleeve and the supporting seat; a bearing component is arranged at the tail end part of the shaft head and is provided with a bearing, a bearing housing and a bearing gland; the bearing is fixedly arranged atthe tail end part of the shaft head in a sleeving manner; the bearing is arranged in an airtight space formed by the bearing housing and the bearing gland in an enclosing manner; a first oil seal fora shaft is arranged between the bearing housing and the shaft sleeve in a connecting manner; a cavity is formed by the shaft sleeve, the supporting seat and the bearing housing and is sequentially provided with an annular balance cavity and an annular filler cavity from left to right; a sealing structure component of the annular balance cavity comprises a first sealing ring, a second sealing ring,a first R-shaped oil seal and a second R-shaped oil seal; and a sealing structure component of the annular filler cavity comprises a filler chamber, a filler gland and filler. The shaft sealing device can be widely applied to the technical field of reaction kettles.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a shaft sealing device for a horizontal reactor and the horizontal reactor. Background technique [0002] Petrochemical equipment is increasingly becoming large-scale. Large-scale is conducive to the production and manufacturing units to increase output value, reduce costs, and increase economic benefits; stirred reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicine, and food to complete vulcanization, Pressure vessels for nitrification, hydrogenation, alkylation, polymerization, condensation and other processes. The main factors affecting the stirring effect of the large-scale stirring reactor include the enlargement of the reactor body, the enlargement of the agitator, the enlargement of the stirring power, the enlargement of the sealing device, the enlargement of each nozzle, etc.; these main factors The influencing factors need to be enlarged a...

AI Technical Summary

Problems solved by technology

In the production process, the stirring shaft of the horizontal reactor generally has a large shaft diameter and is buried in the reaction material, so there is a problem of difficult sealing. At present, after the shaft sealing device of the horizontal reactor is installed and operated for a period of time, due to the infiltration of the reaction material , high-heat gas penetration and high-temperature heat conduction and other adverse factors, the shaft seal wears, ages, and deforms prematurely, making it difficult to maintain the seal, and the sealing effect is accelerated and weakened to failure, affecting normal production
