AI Technical Summary
Technical Problem
Traditional bottom-entry crystallization agitator mechanical seals are prone to increased wear due to the infiltration of material crystal particles, resulting in a shortened service life.
Method used
An isolation chamber and a lip seal are added above the mechanical seal. Flushing water with a pressure higher than that inside the vessel is introduced into the isolation chamber through a flushing pipe to form an isolation chamber, preventing material from entering the sealing chamber and cooling and lubricating the sealing ring.
Benefits of technology
It effectively prevents materials from entering the sealing cavity, reduces equipment failure rate, and extends the service life of mechanical seals.

Abstract
本实用新型公开一种底入式搅拌机封辅助隔离装置，包括安装底板，安装底板中心处设有通孔，通孔底部设有机械密封，通孔穿设有搅拌轴，通孔设有向上凸起的凸环，凸环顶部设有唇封，唇封、凸环和机械密封配合形成隔离腔，搅拌轴向下穿过机械密封，搅拌轴向上依次穿过隔离腔和唇封，隔离腔连通有冲洗管；本实用新型在机械密封上方增设凸环，在凸环与搅拌轴之间设置唇封，使得唇封、凸环和机械密封配合形成隔离腔，并往隔离腔内接入高于釜体内压力的冲洗水，冲洗水可以经唇封处向釜体内渗透；从而阻止釜内物料进入密封腔，机械密封机械密封直接接触冲洗水，冲洗水能够对机械密封起到降温润滑作用；降低设备故障率，延长机械密封使用寿命。
