Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically to a device for cleaning residual liquid from the base of a horizontal screw centrifuge. Background Technology

[0002] A horizontal screw centrifuge, also known as a horizontal spiral sedimentation centrifuge, is a highly efficient centrifugal separation device. The centrifuge works on the following principle: the drum and the screw conveyor rotate at high speed in the same direction with a certain differential speed. Material is continuously introduced into the inner cylinder of the screw conveyor through the feed pipe, accelerated, and then enters the drum. Under the action of centrifugal force, the heavier solids deposit on the drum wall, forming a sludge layer. The conveying screw continuously pushes the deposited solids to the conical end of the drum, where they are discharged from the machine through the discharge port. The lighter liquids form an inner liquid ring, continuously overflowing from the large end of the drum through the overflow port and discharged from the machine through the drain port. This machine can continuously feed, separate, wash, and discharge at full speed. It features a compact structure, continuous operation, stable operation, strong adaptability, large production capacity, and convenient maintenance. Widely used in chemical, light industry, pharmaceutical, food, and environmental protection industries, existing horizontal screw centrifuges often leave a lot of liquid residue at the base during use. However, this liquid is located inside the machine body, making it inconvenient for staff to clean and causing unnecessary trouble for subsequent use. Utility Model Content
