Description

Technical Field

[0001] This utility model relates to the field of bearing housings, and more particularly to a bearing housing structure for a stirring vessel. Background Technology

[0002] Agitators are commonly used equipment in the production of chemical products. Existing agitators typically utilize an agitator shaft that rotates continuously in a certain direction for a certain period of time. The bottom of the existing agitator shaft is supported by a bearing seat to ensure stable rotation.

[0003] The existing bearing housing has poor sealing performance. When gaps appear in the bearing housing, dust from the outside air will enter the gaps and adhere to the bearing, causing the bearing to become clogged. Lubricating oil will also leak through the gaps, resulting in insufficient lubrication of the bearing, a short service life, and affecting the smooth rotation of the agitator shaft.

[0004] Therefore, it is necessary to provide a new bearing housing structure for the stirred tank to solve the above-mentioned technical problems. Utility Model Content
