Description
The present invention relates to centrifuge, specially refer to the centrifuge of rotary rotating cylinder.
Spiral discharge sedimentation centrifuge is a kind of good to material adaptability, the continuous centrifuge that range of application is wider.The LW-450 type horizontal spiral discharge sedimentation centrifuge that Shanghai chemical produces discloses the structure of this type.It is by the rotary drum belt pulley, the differential belt pulley, differential mechanism, charge pipe, casing with two kinds of material outlet pipelines is contained in the rotary drum that has mud hole of two parts-outsides of circling round on the base bearing and the inner auger conveyor with spiral blade with one heart and constitutes.Rotary drum is by the big end cap that has spout hole, and little end cap and cylinder-conical rotor drum cylindrical shell constitutes.Motor drives rotary drum belt pulley and differential belt pulley by V belt, utilizes differential mechanism to make rotary drum and auger conveyor do to rotate in the same way, but has speed discrepancy between them, and revolutional slip is 0.2-3%.Suspension adds in the rotary drum from charge pipe continuously, under the centrifugal action of drum rotating, form a ring-shaped pool in the rotary drum, solids are formed sediment to the drum inner wall face and are got rid of sediment outlet into casing by the afterbody that the blade on the auger conveyor is pushed to rotary drum from mud hole by centrifugal sedimentation.The spout hole that is provided with on the big end cap of rotary drum can be derived clarified solution and enter the clear liquid outlet of casing, thereby reaches the purpose of separate out suspended liquid.When needs separate the suspension of some particle diameter distribution wide (from several microns to tens microns even several millimeters), not only bulky grain to be formed sediment, and will some particular requirement liquid be divided into " weight " liquid phase and concentrated " gently " liquid phase two parts of fine grained that coarse granule is concentrated, here " weight " and " gently " is not that the difference of specific gravity of liquid itself causes, but because the different caused apparent specific gravities of liquid endoparticle thickness degree (or claiming apparent specific gravity (gd)) difference is caused.Generally speaking, when adopting spiral discharge sedimentation centrifuge to operate, centrifuge is rotated at a high speed, separating factor is greater than 3000G, " gently " liquid phase and " weight " liquid phase could there be one " layering " significantly, " gently " liquid phase is overflowed from spout hole, and " weight " liquid phase is discharged from slag-drip opening with oarse-grained sediment.This lock out operation need consume more energy.When " weight " liquid phase of separating needs further to handle, be the higher underflow of water capacity often, cause the difficulty in the transportation because of what separate; Just can handle but also its further dilution will be removed the bulky grain sediment that is mingled in wherein.
The objective of the invention is to avoid above-mentioned weak point of the prior art and provide a kind of energy consumption lower, the novel centrifugal machine that can the suspension that particle diameter distribution is wider be separated into satisfactory " gently " liquid phase-" weight " liquid phase-sediment simple in structure.
Purpose of the present invention can realize by following technical measures: by the rotary drum belt pulley, and difference band belt pulley, casing, charge pipe has in the spiral discharge sedimentation centrifuge that the rotary drum of mud hole and auger conveyor constitute, and rotary drum is by big end cap, little end cap, cylinder-conical rotor drum cylindrical shell is formed.On big end cap, double-deck outage is set.That is to say: the radial direction along big end cap is provided with the bigger draining overflow hole in one or more apertures near rotating shaft, for concentrated " gently " liquid phase overflow discharge opeing of fine grained; And the throttling outage of the less control flow in one or more apertures is set between spout hole and big end cap edge, and " weight " liquid phase that coarse granule is concentrated is full of throttle orifice and discharge opeing, and its flow is subjected to the limited aperture of throttling outage.The pore size in these two kinds of holes and " gently ", " weight " liquid phase flow are relevant.Bernoulli's equation in the available stream mechanics is tried to achieve.
Motor drives rotary drum and the equidirectional rotation of auger conveyor by two belt pulleys, and their revolutional slip is 0.2-3%.When the wider suspension of particle diameter distribution entered rotary drum continuously from charge pipe after, because the centrifugal action of rotary drum, suspension was divided into three layers very soon.The bulky grain sediment nestles up drum inner wall, and auger conveyor constantly rotation constantly scrapes and discharge rotary drum with sediment, discharges from the pipeline of slagging tap of casing." weight " liquid phase that coarse granule is concentrated is between drum inner wall and " gently " liquid phase, and " weight " liquid phase is full of the throttling outage and also constantly enters casing from throttle orifice, limited aperture flow, from the coarse granule suspension pipeline of casing, discharge." gently " liquid phase that fine grained is concentrated occupies the innermost layer of the interior liquid pool of rotary drum, and overflow from draining overflow hole and going out is discharged from the fine grained suspension pipeline of casing.Reached the purpose of suspension three phase separation.
Sometimes in order to prevent that " gently " liquid phase and " weight " liquid phase from mixing, annular baffle is set in the inboard of end cap greatly.
The present invention also can be used to handle the three-phase mixture of the different light liquid-heavy-fluid of proportion-solid phase.Also be applicable to the vertical helical discharging sedimentation centrifuge.
Compared with prior art utilize the present invention to handle the wide suspension of particle diameter distribution, do not need very high separating factor, test shows that separating factor is that 2500G just can be separated into the bulky grain sediment with this suspension effectively, " gently " liquid phase three parts that " weight " liquid phase that coarse granule is concentrated and fine grained are concentrated.And " weight " liquid phase does not form underflow, convenient transportation when further handling.Structure of the present invention is also simpler, and is easy to make.
