Description
Technical field
The present invention relates to a kind of down-transmission type centrifugal extractor that is used for chemical industry operation, belong to technical field of chemical.
Background technology
The existing top suspension centrifugal extractor that is used for chemical industry operation, promptly singletable one-stage formula centrifugal extractor is to integrate to mix a high-efficiency appliance of clarifying, its structure as shown in Figure 1, among Fig. 1, the 1st, motor, the 2nd, loam cake, the 3rd, blending tank, the 4th, heavy phase weir, the 5th, heavy out, the 6th, rotary drum, the 7th, two-phase import, the 8th, light phase collecting ring, the 9th, light phase export, the 10th, heavy phase collecting ring, the 11st, light phase weir, the 12nd, rotating shaft.As can be seen from the figure its allows liquid liquid two-phase fully to mix and does not influence the separation of two-phase in equipment, in same equipment, mix under centrifugal action simultaneously greater than thousands of times of gravity, realize separating fast, make to mix and be separated in the extremely short time and finish.Can be used for single-stage extraction, also can many series connection carry out separating and water washing cleaning technology in multi-stage counter current extraction and the chemical industry operation.Substitute batch-mixed stirred tank, continous way mixer-settler and various tower equipment.Extensively be used in the extraction of hydrometallurgical extraction method, separation and purified product; In the fine chemical product and water washing cleaning; In the petrochemical industry product is separated and purify; Environmental protection industry extracts useful from waste water or removes field such as harmful substance, because it is simple in structure, is easy to processing and manufacturing, and is cheap, adapts to characteristics such as material properties wide ranges, in chemical industry, hydrometallurgy.Enterprises such as medicine, environmental protection have obtained extensive use.
But the above-mentioned top suspension centrifugal extractor weak point of using is at present: (1) is because selecting for use of heavy phase weir size is according to material two-phase difference in specific gravity, viscosity and stream ratio difference and determine, different materials and operating condition need the heavy phase weir of different size to regulate, therefore different material properties and process conditions must be changed the heavy phase weir of different size, therefore this centrifugal extractor all be equipped with or the heavy phase weir of tailor-made different size so that satisfy technological requirement, but the top suspension centrifugal extractor more must be connected the transmission mechanism on top during the commutation weir with it rotary drum hangs out together, again rotary drum is unloaded the replacing of carrying out the phase weir, replacing finishes and loads onto rotary drum more again and reinstall to original position together with transmission mechanism, the substitute mode trouble, and every dismounting once all has loss to the precision of centrifugal reel, so some enterprise mostly is not more commutation weir, this just causes equipment not work under optimum condition, this use to centrifugal extractor is a very big waste, even the enterprise that has just thinks that equipment can not use because the phase weir is improper can not satisfy technological requirement.(2) present centrifugal extractor is because be top suspension, and promptly running part is on the top of equipment, accounts for the big portion weight of entire equipment together with motor, be main body heavy 4/5ths.Form the labile state of top heavy, especially main equipment is shaken greatlyyer when revolution is higher,, just must be placed on whole centrifugal extractor on the bigger underframe in order to stablize center of gravity.Make complete equipment seem heavy.
Summary of the invention
The objective of the invention is to propose a kind of down-transmission type centrifugal extractor that is used for chemical industry operation, by changing the structure of existing top suspension centrifugal extractor, to reach three purposes: (1) is convenient for changing the phase weir and guarantees that equipment uses under optimum performance; (2) more need not drive disk assembly and rotary drum are pulled down together during the commutation weir, guarantee equipment precision and increase the service life; (3) running part makes this high rotating speed equipment operation more steadily reliable at bottommost.
The down-transmission type centrifugal extractor that is used for chemical industry operation that the present invention proposes comprises loam cake, extractor shell, rotary drum and motor.Loam cake is embedded to be covered on the extractor shell.Rotary drum is installed in the center of extractor shell, and extractor shell left-hand thread is on rotary drum, and rotary drum is by rotating shaft and motor linkage.Be provided with heavy phase collecting ring and light collecting ring mutually between extractor shell and the rotor cover, extractor shell between the loam cake of heavy phase collecting ring and extractor shell is provided with heavy out, extractor shell between heavy phase collecting ring and the light phase collecting ring is provided with light phase export, and the extractor shell between light phase collecting ring and the extractor outer casing bottom is provided with the two-phase import.
The down-transmission type centrifugal extractor that is used for chemical industry operation that the present invention proposes, its characteristics and advantage are:
Motor and drive disk assembly are located at the most beneath of main equipment, make the weight of entire equipment move down into bottommost, have therefore guaranteed that equipment operates steadily; Simultaneously when commutation weir more, need not dismantle rotary drum, as long as open both tops of blending tank of loam cake, get final product more commutation weir and maintenance of equipment at any time, and loam cake need not seal, use the pressure formula of kowtowing to connect and get final product, do not destroy machining accuracy, prolong service life of equipment, be convenient to adjust device parameter, make its performance optimum performance according to different process requirement and material properties.Down-transmission type centrifugal extractor after the present invention improves, the rotary drum drive feed liquid of rotating is at a high speed rotated with static outer casing inner wall generation friction generation eddy current and is mixed, moment is finished mass transfer, mixed liquid is sent into rotary drum by the shell bottom blade and is separated, gently, the passage of heavy phase by separately enters collecting ring, discharge through light, heavy phase outlet, finish the work.Compact conformation, stable, more reasonable at aspects such as use, maintenances, more be applicable to the manufacturing main equipment, for utilizing widely in conglomerate, centrifugal extractor provides extraordinary version.
