Description
Technical field
The utility model relates to vacuum dryer, especially relevant with the mounting structure of magnetic fan in vacuum dryer.
Background technology
Vacuum dryer comprises the equipment of several kinds such as voltage transformation vacuum dry, heat-wind circulate drying, gas phase drying.Wherein voltage transformation vacuum dry, heat-wind circulate drying main purpose are by constantly heating and making inner air convection current, to make dry products heat up fast, evenly, make interiors of products moisture energy rapid evaporation and cause product to get rusty at the inner unlikely formation low temperature blind spot of drying equipment.
Current vacuum dryer is because the blower fan movable sealing structure under needing solution complex environment, and adopt Inner eycle blower fan and drive motors entirety so basic by seal closure piece cover on device interior cavity top, this mode can bring a series of problem:
1, drive motors is because be placed on vacuum tank top, and the steam of the evaporation when vacuum tank heats rises, and causes drive motors to work under high temperature hygrothermal environment for a long time, very easily causes motor internal iron core oxidation and rusting, thus cause coil short and damage.
2, in this kind of structure, drive motors needs by cooling at electric machine casing outer disk copper pipe.Because drive motors is in vacuum tank, cannot dispel the heat when running under vacuum conditions, usually employing dish cylinder copper pipe cooling at present, although this structure can solve drive motors heat dissipation problem, but often because drive motors drives vibrations during fan operation to cause, copper pipe is worn out to leak, and because frequent vibrations easily cause seal point to leak gas between cooling copper tube import and export connect with seal closure, cause equipment fault.
3, drive motors is directly connected with blower fan, and namely blower fan reaches maximum speed in startup, is easily hit and transships when fan starting resistance is excessive, causes that blower fan attachment bolt loosens, drive motors electric current exceeds standard, and forms potential safety hazard.
4, drive motors is arranged in vacuum tank, cannot run when equipment vacuumizes.Drive motors cannot run when vacuum dryer vacuum is higher, cannot dispel the heat when drive motors runs under high vacuum state, causes motor overheating to burn.
