Liquid-liquid extraction - Centrifugal extraction equipment structure parts
a, external structure
you can see, from the appearance of 50 type centrifugal extraction machine is composed of: motor, shell, front-rear tube, emptying valve, the pipeline between five parts. :
1, the motor speed 2799 revolutions per minute, 0. 18 kw/Taiwan.
2, shell: there are two inlet, two discharging mouth, the highest heavy phase export, export the second light, light and heavy phase under export import symmetrical distribution, two phase import height.
3, front-rear tube:. cwl - M50 centrifugal extraction machine front-rear tube using four fluorine transparent tube, is advantageous for the observation of material between liquid level in the movement, such as feeding and discharging.
4, feeding valve.
5, interstage piping: connection centrifugal extraction machine at all levels, can be continuous, multi-stage extraction.
2, internal drum
centrifugal extraction machine internal drum, corrosion resistance, high dynamic balancing precision, etc.
2 weight on the drum in imports and exports two weight, weight of two phase solution according to certain proportion respectively from two feeding tube into the drum and shell type ring gap formed between the mixed zone, with the aid of the rotation of the drum, through the turbine disc and the impeller to make two phase mixing and dispersing quickly, two phase solution fully mass transfer. Mixture under the action of vortex disk into the rotary drum, in the plate to form the bulkhead area, mixture quickly with synchronous rotary drum, in under the action of centrifugal force, the heavier than major phase fluid in the process of upward mobility and gradually away from the drum center on the drum wall; Small proportion of liquid phase gradually away from the drum wall and on to the center, after clarification of two phase fluid end respectively through their weir plate into the collection chamber and the tube was closed to derivation, respectively, to complete two phase separation process.
it is worth mentioning,. cwl series centrifugal extraction machine design has a variety of mixed structure, can satisfy the customer different material strength of the hybrid system demands, avoid material liquid emulsification by mixing intensity is too large, the power consumption is too large, the occurrence of the phenomenon such as separation effect is bad.
3. cwl - M centrifugal extraction machine other structural advantage
1, hanging on the domestic structural design. Efficient centrifugal extraction device for hanging structure, only the upper set equipment has the bearing and from the processing area of material liquid, no bearing material liquid at the bottom of the mixed area, improved the security of the equipment operation from the structure.
2, totally enclosed system design. Centrifugal extraction system is fully enclosed, avoid volatile gas ( Organic gas and acid gas) Leak, more environmental protection, safe extraction production line.
3, for liquid containing corrosive material, extraction invested heavily to develop high polymer composite material, not only satisfy the strength of equipment required, but also solves the acid, alkali, solvent corrosion problems.
4, according to requirements of form a complete set of temperature control system, operation platform, peristaltic pump and so on.
