The utility model content
The utility model technical issues that need to address provide a kind of complete machine geometric center and overlap substantially with center of gravity, and are in light weight, can reduce the vibrating motor load, and alleviating high-temperature hot-air influences vibrating motor, increases the Vibratingfluidbeddrier of electrical machinery life.
For addressing the above problem, technical solution adopted in the utility model is: a kind of Vibratingfluidbeddrier that improves the vibrating motor life-span, comprise, lower box, upper box, dispersion plate, be positioned at air inlet and discharging opening on the lower box, be positioned at the exhaust outlet on the upper box, be fixed in the vibrating motor on the lower box, be used to support the support of lower box, the vibration isolation spring that is used for vibration damping, wherein said support is machine rack independently, be supported on the flange place of lower box by the vibration isolation spring, make no longer load-bearing of lower box, and reduced machine gravity, described lower box is the simple case structure that is formed by plate sheet welding, geometric center place on lower box bottom lengths direction is provided with the open area of a prism-shaped, this open area is exposed in the air fully, not influenced by high-temperature hot-air, two faceted pebbles of this open area are divided into two independently chambers with thin plate with lower box, on the thickening side plate of this open area vibrating motor is installed, this novel complete machine geometric center in the longitudinal direction overlaps substantially with the center of gravity projection.
The support of described support for being made by shaped steel, each support is fixed on the basis by foundation bolt.
The open area geometric center of described prism-shaped overlaps with lower box geometric center in the longitudinal direction, the two triangle side plate two sides of this open area all expose with air in, between biside plate, also be connected with the connector that is used to strengthen intensity.
Adopt the beneficial effect that technique scheme produced to be: the utility model adopts independent rack, move on the strong point, center of gravity moves down, lower box is load-bearing no longer, vibration more becomes steady, complete machine geometric center along its length overlaps substantially with the center of gravity projection in addition, and machine weight greatly alleviates, and generally can reduce by 20～40%, the corresponding minimizing of required exciting force, the vibrating motor load alleviates, and vibrating motor comes from the high-temperature region disengaging, has reduced the heat transmission and the heat radiation influence of hot blast, improved radiating condition, temperature rise reduces significantly, and the lubricated of motor bearings is guaranteed, and has improved electrical machinery life greatly.In sum, the utlity model has in light weightly, cost is low, vibration steadily, characteristics such as exciting force is little, and is energy-conservation, and the vibrating motor temperature rise is little, and the life-span is long.
