Anhydrous mechanical shaft sealing structure of bearing support for a side entry type stirrer

Abstract

The invention provides an anhydrous mechanical shaft sealing structure of bearing support for a side entry type stirrer. The anhydrous mechanical shaft sealing structure of bearing support for the side entry type stirrer comprises a shaft sleeve with one end provided with a shoulder portion, a gland, a stationary ring and a movable ring. The shaft sleeve is connected to the shaft in a sleeving manner. The movable ring abuts against the shoulder portion of the shaft sleeve. The movable ring abuts against the end face of the stationary ring. The gland comprises a first gland and a second gland fixed together with the first gland. The gland is connected to the shaft sleeve in a sleeving manner, and the first gland is connected to the outer side of the stationary ring in a sleeving manner. A spring is arranged between the end of the stationary ring and the first gland. A framework oil seal is arranged between the second gland and the shaft sleeve. The end, far away from the first gland, ofthe second gland is provided with a drive ring. The shaft is connected with a bearing in a sleeved manner, wherein the bearing is fixed and limited through a bearing seat. The end, far away from thedrive ring, of the bearing seat is provided with a bearing head cover. The anhydrous mechanical shaft sealing structure of bearing support for the side entry type stirrer enhances the rigidity of thebearing for the shaft and can save water resource, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the field of mechanical seals, in particular to a waterless mechanical seal structure for a bearing supporting shaft of a side-entry agitator. Background technique [0002] The side-entry mixer is to install the mixing device on the side wall of the equipment cylinder. The mixer on the mixer usually adopts the axial flow type, and most of them are push-type mixers. Under the condition of the same power consumption, the highest mixing effect can be obtained. , widely used in desulfurization, denitrification, and stirring of various large storage tanks or storage tanks. The mechanical seal of the prior art agitator with back flushing water device wastes water and when the on-site staff opens the back flushing water, the pressure If it is too large, the skeleton oil seal of the mechanical seal will be damaged, resulting in failure of the mechanical seal. At present, the agitator is supported by the bearing of the pulley decelerat...

[0002] The side-entry mixer is to install the mixing device on the side wall of the equipment cylinder. The mixer on the mixer usually adopts the axial flow type, and most of them are push-type mixers. Under the condition of the same power consumption, the highest mixing effect can be obtained. , widely used in desulfurization, denitrification, and stirring of various large storage tanks or storage tanks. The mechanical seal of the prior art agitator with back flushing water device wastes water and when the on-site staff opens the back flushing water, the pressure If it is too large, the skeleton oil seal of the mechanical seal will be damaged, resulting in failure of the mechanical seal

At present, the agitator is supported by the bearing of the pulley deceleration belt, which inevitably requires the mechanical seal to have good bearing support. Poor support rigidity
