Industrial Electric stirrers are applicable in different industrial sectors chemical, pharmaceutical, food processing, liquid soap, etc.
Ideal for mixing liquid at slow speed, these industrial stirrers are admired for their superior surface strength, easy usage, moist-proof nature, and long functional life.
The stirrer Machine can be used for a wide variety of applications Including Mixing- Paint, Putty, Cement, Bird Feed, Chemicals, Diatom Mud Etc.
Construction:
In typical mixing operations, the impeller is attached to a vertical stirrer shaft that passes from the motor through the top of the vessel.
Parts of Industrial Electric stirrers:
Baffles: These are vertical strips of metal mounted against the wall of the tank, and are installed to reduce gross vortexing and swirling of the liquid.
Impeller:
Mixing is achieved using an impeller mounted on a centrally located stirrer shaft.
Stirrer shaft:
The stirrer shaft is driven rapidly by the stirrer motor; the primary function of the stirrer shaft is to transmit torque from the stirrer motor to the impeller. Torque is the tendency of a force to cause an object to rotate.
The magnitude of the torque around the shaft axis is related to the power required for the operation of the impeller. The stirrer shaft also performs other mechanical functions: it resists the bending forces created by the impeller, it limits any lateral deflections, and it supports the impeller weight. These functions must all be achieved without excessive vibration.
Sparger:
In gassed stirred tanks such as bioreactors used for aerobic culture, gas is introduced into the vessel by means of a sparger located beneath the impeller.
Stirrers Motor and Gearbox Drive Unit:
This stirrer motor features a totally enclosed Electric motor and two output shafts. Use the geared shaft when you need higher torque and lower speeds up to 300 rpm.
The direct-drive shaft when you need higher speeds up to 5000 rpm and lower torque.
STIRRER Motor is two types geared motor and without gearbox also.
Motorized Gear Unit:
Gear units of double and triple reduction types are used as standard assemblies with flanged motors directly mounted on gear case input shaft housing by adaptors. Motor and gear unit shafts are connected by a flexible coupling.
Worm Gearboxes:
Worm gearboxes provide high torque with a low-speed gear ratio. Being simple and compact in design, these gears can achieve a higher gear ratio than helical gears. These worm reduction gears having screw-type qualities are similar to helical gears, but their helix angle is typically comparatively larger) and its body is normally quite long in the axial direction.
Double Reduction Worm Gear Units are constructed using two single reduction worm gear units. These gear units are particularly suitable for high torque slow-speed drives.
Heavy-Duty Industrial Electric Stirrers:
Heavy Duty Stirrer unit incorporates an extended bearing housing to accommodate a larger bottom bearing and increased shaft size, thereby enhancing the unit capacity to absorb the high bending loads imposed during stirrer applications. This gear unit is compact with the facility of top mounted pivoted platform where an electric motor can be directly mounted above the gear unit using a belt tensioning device.
Stirrer Electric Motor Controller:
- The electronic motor controller features feedback circuitry that maintains speed even with viscosity changes.
- Filtered circuitry ensures smooth rotation for repeatability in homogenizing and greatly reduces motor temperature and noise.
- The reversing switch lets the motor shaft rotate in either direction and reverses the pestle direction during homogenization.
