Abstract
A sanitary level shaft seal structure is suitable for the field of food machinery and is small in movement friction, high in transmission efficiency and free of sealing dead corners. The structure comprises a rotating shaft, a frame and a liquid storage tank. The frame is provided with a base plate with a middle hole. The frame is fixedly connected under the liquid level of the liquid storage tank. A movable ring assembly and a fixed ring assembly are arranged on the rotating shaft. The movable ring assembly is fixedly connected onto the rotating shaft, and the fixed ring assembly is connected onto the frame. The movable ring assembly comprises a fixed seat, a movable ring, a pin and a stop screw. The fixed ring assembly comprises a top plate with a middle hole, an annular elastic piece and a fixed ring. The inner diameter of the middle hole is larger than the outer diameter of the rotating shaft. The structure achieves dead-corner-free shaft sealing. All rotating parts are in a full symmetrical structure to ensure good dynamic balance performance. All sealing pieces are free of sanitation dead corners and are washed clean in CIP washing.
