Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of centrifugal purification equipment for benzophenone, and in particular to a centrifugal purification equipment for benzophenone. Background Technology
[0002] Because centrifuges rotate at very high speeds, and the movement of materials causes a slight eccentricity at the end furthest from the shaft, the higher the centrifuge speed, the greater the eccentric force. This leads to a larger radial load on the shaft, which intensifies the wear of the bottom bearing, affects the equipment's lifespan, accelerates the consumption of bearing lubrication, and easily causes insufficient lubrication, thus leading to abnormal noises.
[0003] For example, the publication number is CN212842509U
[0004] This invention relates to the field of dewatering equipment technology and provides a centrifugal dewatering machine. Traditional centrifuges, after high-speed rotation, cause powder to accumulate on the side wall of the centrifuge drum, requiring manual cleaning, resulting in low efficiency and a heavy workload for workers. This invention includes an outer cylinder mounted on a base, with a cap at the top. An inner cylinder, rotatably mounted on the base, is located within the outer cylinder. The inner cylinder is covered with several sieve holes and contains a ring-shaped cleaning ring with the same cross-sectional shape as the inner wall of the inner cylinder. The cleaning ring is slidably connected to the inner wall of the inner cylinder. A slot is provided on the cap, and a rod is inserted into the slot. A limiting piece is located at the bottom of the rod. After the rod is inserted into the slot, the limiting piece is positioned on the side of the top of the cleaning ring. The insertion of the rod into the slot restricts the rotation of the cleaning ring, causing relative rotation between the cleaning ring and the inner cylinder. The cleaning ring cleans the material on the inner wall of the inner cylinder, improving cleaning efficiency, replacing manual labor, and reducing labor intensity.
[0005] We found that when the centrifuge tube rotates at high speed, only the lower shaft is constrained by the bearing, while the upper structure is longer and has a large eccentric force after bearing the weight, which will aggravate bearing wear, resulting in larger clearance and shorter life.
[0006] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
