Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of horizontal centrifuges and relates to a horizontal multi-stage continuous sedimentation centrifuge with a buffer structure. Background Art
[0002] A horizontal centrifuge is a device commonly used for solid-liquid separation. It uses the centrifugal force generated by the high-speed rotating drum to trap the solid particles in the suspension in the drum and automatically discharge them under the action of force. At the same time, under the action of centrifugal force, the liquid in the suspension is thrown out through the filter medium and the small holes of the drum, thereby achieving the purpose of liquid-solid separation and filtration. There are many types of horizontal centrifuges, one of which is a horizontal spiral centrifuge. This is a spiral unloading sedimentation centrifuge. Its working principle is to push the solid particles to the small end of the drum through the blades on the spiral pusher, and the liquid overflows through the overflow hole at the large end of the drum. This centrifuge can achieve the purpose of continuous separation through continuous circulation. If the horizontal centrifuge cannot maintain stable operation, a series of problems will arise, as follows:
[0003] First, unstable centrifuge operation will lead to reduced separation effect. The core function of the centrifuge is to use centrifugal force to separate solids and liquids in the material. If the machine is unstable, the magnitude and direction of the centrifugal force will constantly change, making it impossible for solid particles to effectively settle to the bottom of the centrifuge, resulting in reduced separation effect and affecting product quality.
[0004] Secondly, unstable operation will lead to increased wear of the equipment. When the centrifuge is rotating at high speed, if the operation is unstable, the friction between the various components will increase, accelerating the wear of the equipment and shortening the service life of the equipment. This will not only increase the maintenance cost of the enterprise, but also may cause production interruption and affect the normal operation of the enterprise.
[0005] In addition, unstable operation may also cause safety issues. If the centrifuge vibrates too much, it may cause the equipment to suddenly shut down or other failures, and in serious cases may even cause equipment damage or casualties. This will not only cause economic losses to the company, but may also affect the company's reputation and image.
[0006] Therefore, it is very important to maintain the stable operation of the horizontal centrifuge. In order to achieve this goal, enterprises need to regularly maintain and service the equipment to ensure that all parts of the equipment are in good working condition.
