Description
One, technical field:
The utility model relates to the Highspeedcentrifugingandsprayingdrier technical field, particularly the atomizer of high speed centrifugation spraying machine.
Two, background technology:
Highspeedcentrifugingandsprayingdrier is to be used for liquid material is spray dried to the powdery finished product, as the achievement crystalline flour is done in fruit juice spray, becomes traditional Chinese medicine powder the Chinese medical concrete spray is dried.The rotating speed of Highspeedcentrifugingandsprayingdrier should be between 15000～40000r/min, and the more little rotating speed that requires of type is high more, and the mist of injection is apart from just short more, is sprayed onto on the wall avoiding.Per hour the minicomputer of evaporation water deal 5 liters should reach the atomizing effect that 40000r/min just can obtain satisfaction.And the atomizer that small-sized drying machine with centrifugal spray at present both domestic and external adopts mostly is a pneumatic sprayhead, pneumatic sprayhead generally can only reach 27000r/min, the mist square is too big, and when air pressure fluctuation, material concentration variation or feeding quantity change, rotation speed change is very big, it is very unstable to atomize, and often has wet feed to be sprayed onto on the wall, and production can't be proceeded.And large scale computer is because rotating speed is lower, roughly below 20000r/min, all adopt the gear drive atomizer of gear speedup case speed change both at home and abroad, but its gear speedup case is very high to material and requirement on machining accuracy, manufacturing cost costliness, and the gear train of rotation at a high speed, its noise, vibration are very big, serious wear often causes the damage of parts such as main shaft and gear and influences production.The atomizer that adopts high-speed electric main shaft directly to connect atomizing disk is also arranged at present, just directly spray disk is fixed on the high-speed electric main shaft with nut, the result who does like this is that the vibrations of spray disk directly are relayed on the bearing at electric main shaft and two ends thereof, when bad or sizing was too much when the spray disk dynamic balancing, the vibrations of electric main shaft were too big, do not reach the rotating speed of expection, and produce and shout strangely, spray thing drying can't be carried out, therefore can only be used to not be afraid of sticking wall, it is overheated not to be afraid of, on bigger some chemical products of proportion, it is little to adapt to proportion, and viscosity is big, and fusing point is low, be afraid of sticking wall, be afraid of overheated material, such as Chinese medical concrete, the spray-drying of health nutrient and so on material.
Three, summary of the invention:
The purpose of this utility model is the deficiency at existing atomizer, a kind of high speed centrifugation atomizer is provided, it is higher to have rotating speed, vibrate littler, it is more stable to turn round, characteristics such as longer service life are particularly useful for that proportion is little, viscosity is big, fusing point is low, are afraid of sticking wall, are afraid of overheatedly as Chinese medical concrete and health nutrient one class, are difficult to the atomizing requirement of spray-dired material.
The purpose of this utility model is achieved in that a kind of high speed centrifugation atomizer mainly comprises high-speed electric expreess locomotive and electric machine main shaft, nylon block, shaft coupling, big tie-plate, atomizer main shaft, spray disk and bearing etc., high-speed electric expreess locomotive is connected with the big tie-plate of atomizer by support, the high-speed electric expreess locomotive main shaft separates with the atomizer main shaft, the high-speed electric expreess locomotive main shaft is flexible coupling by upper coupling, nylon block and following shaft coupling and atomizer main shaft, power transmission medium between two main shafts is a nylon block, has damping effect.The atomizer main shaft is a flexible axle, axle journal below its intermediate bearing is thinner, in several subresonances that allow it in starting process, to produce certain swing is arranged, the amplitude of its swing is limited by leaving bigger gap between the oil-containing floating bearing of the supporting mass bottom that is arranged at the bearing housing lower end and the atomizer main shaft, can eliminate of the infringement of several subresonances like this to the atomizer main shaft, make stabilization of speed, prolong the service life of main shaft.High-speed electric expreess locomotive also is provided with the water-cooling jacket device cools off and fog lubrication, feed the heat that cold water can be taken away bearing and motor stator generation in the water-cooling jacket; Mist of oil and compressed air also can be taken away the heat that bearing and motor stator produce, thereby make high-speed electric expreess locomotive be in running under the normal temperature, have prolonged the service life of motor, have improved the rotating speed of high-speed electric expreess locomotive.Adopt lubrication oil circulation lubricated to the main shaft of atomizer, after lubricating oil reached cooling after filtration, circulating lubricating can cooling bearing in machine, and takes away because of fricative iron end and foreign material, prolongs the service life of atomizing parts.
After the utility model adopts technique scheme, have following advantage:
1. drive the atomizer main shaft with high-speed electric expreess locomotive and rotate, than pneumatic sprayhead stabilization of speed and can reach the rotating speed of 40000r/min; Simpler than gear up nozzle structure, noise is low, vibrates for a short time, and the life-span is long, off-axis not, and can reach the inaccessiable rotating speed of gear, satisfied the requirement that is difficult to spray-dired material as Chinese medical concrete and so on.
2. with the transmission of nylon block as two between centers torques, the vibration that high-speed electric expreess locomotive main shaft and atomizer main shaft are produced does not separately interact, and the structural vibration that directly connects atomizing disk than existing high-speed electric expreess locomotive is little, can reach higher rotating speed, and is not fragile.
3. the atomizer main shaft adopts flexible axle, can eliminate the infringement of the vibration of several resonance regions generations to machine, makes rotating speed steady.
4. motor adopts water-cooled to take away the heat of motor bearings and stator generation; Adopt oil foglubrication, except the permission rotating speed that improves motor bearings, also can take away heat and impurity that bearing produces.Prolonged the service life of bearing.
5. the atomizer base bearing adopts oily circulation cooling and lubricating, has improved the bearing service condition, has improved the rotating speed allowable of atomizer bearing.
6. the recycle oil through supercooling and filtration circulates in atomizer, has taken away heat and iron filings impurity that the shower nozzle running produces, has prolonged shower nozzle service life and time between overhauls(TBO).
The utility model can be widely used in high velocity fog drying machine and other industrial circle, in aqueous material spraying drying powder-forming shape finished product.
