Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of thin film evaporator detection, and in particular relates to a vibration detection device for a thin film evaporator. Background Art
[0002] Thin film evaporator is mainly used in albumin preparation, polypeptide and other industries to evaporate organic solvents in the feed liquid, and use the material concentration ratio and solvent residue to meet the dosage standard requirements. The "air knife" formed by the high-speed rotation of the fixed rotating scraper forces the film to form a new type of high-efficiency evaporator that can perform falling film evaporation under certain vacuum conditions. It has a large heat transfer coefficient, high evaporation intensity, short and adjustable flow time, and is especially suitable for evaporation and concentration of heat-sensitive materials and high-viscosity materials, and removal of solvents.
[0003] There is no elastic material between the fixed rotating scraper and the cylinder. In order to ensure the film-forming effect inside, the fixed rotating scraper located inside the cylinder needs to run at a high speed. While ensuring high-speed operation, it is also necessary to ensure that the scraper runs smoothly and without abnormal vibration. It is necessary to strictly follow the ISO1840 specification for strict overall dynamic balancing, that is, all rotating parts are assembled as a whole, and then the overall dynamic balancing test is carried out to control the influence of residual imbalance or eccentricity on it.
[0004] For such high-speed equipment, once the bearing has problems, the fixed rotating scraper will directly scrape against the inner wall of the cylinder, and in more serious cases, the machine will be damaged or scrapped. Therefore, a detection device is needed to monitor the abnormal condition of the bearing in real time. Utility Model Content

[0030] The utility model discloses a vibration detection device for a thin film evaporator. A motor 1 is arranged in the thin film evaporator. The motor 1 drives an output shaft 11 through a coupling 9. The output shaft 11 drives a scraper thereon to rotate, thereby completing high-speed rotation of the scraper. The output shaft 11 is arranged in a bearing seat 2 through a proximal bearing 3 and a distal bearing 4, and an effective double support point can be formed for the output shaft 11. The vibration of the proximal bearing 3 in the Y direction is monitored through a first vibration sensor 5, and the vibration of the distal bearing 4 in the Y direction is monitored through a second vibration sensor 6.
