Description

Technical Field

[0001] The utility model relates to a disc type separator, in particular to an anti-rotation structure of a pump cover of a disc type separator. Background Art

[0002] The disc separator is a high-speed separation equipment used in juice clarification, oil-water separation, biopharmaceuticals and other related fields. Two centripetal pump covers are installed above the drum of the three-phase disc separator to form two chambers for collecting and discharging the separated liquid; in order to prevent leakage of the separated liquid, multiple O-rings are installed on the pump cover to increase the sealing performance. However, in the prior art, there is usually no limit structure designed on the pump cover to prevent it from rotating. Therefore, during the installation process, the pump covers often rotate out of position, resulting in damage to the sealing ring. Once the sealing ring is damaged, it will cause leakage, economic losses and other problems. To this end, a disc separator pump cover anti-rotation structure is proposed. Utility Model Content
