Description
Affiliated technical field
The utility model relates to the separation machinery of the solid, liquid body that is used for separating suspension, especially utilizes the conic basket type centrifuge that the helical resistive materials device is housed in rotary drum in the conic basket type centrifuge of centrifugal unloader.
Background technology
As everyone knows, the conic basket type centrifuge is the centrifuge that utilizes the suffered centrifugal force of rotation material itself to carry out the separation of solid, liquid body and filter residue is drawn off voluntarily in the taper barrel rotary drum of rotation at a high speed.This machine is simple in structure, and no special slag dumping mechanism can feed in raw material automatically under full-speed operation, separates, the operation of operation such as washing, slag dumping; Treating capacity is big, and cost is low, and energy consumption is little.But, because filtrate (slag) taking off the liquid time in " awl basket "----is that filtrate (slag) is done even variable accelerated motion to the required time of big end----of " awl basket " too short (only is 0.04--0.33 second according to the document introduction) from the small end of " awl basket " along bus, to take off liquid not thorough and cause filtrate (slag), make the filter residue liquid content after the separation too high, sometimes even also can form " having loose bowels " phenomenon, thereby limit its application.At present, this machine is mainly used in chemical fertilizer and sugar industry.
For solving this drawback, people install spiral stock stop and the corresponding differential attachment with the rotary drum coaxial line often on the conic basket type centrifuge, the speed discrepancy that makes it to cause taper barrel rotary drum and spiral stock stop of being in operation reaches and delays the filtrate purpose of the holdup time in the taper barrel rotary drum.Drive taper barrel rotary drum and spiral stock stop as other simultaneously by driven by motor cycloidal-pin wheel (or planetary gear) decelerator, to cause this speed discrepancy; Or drive taper barrel rotary drum and spiral stock stop respectively to cause this speed discrepancy with two motors.Owing to cause the differential attachment complex structure of this speed discrepancy, cost an arm and a leg (and especially with the former for very) often makes many users hang back; During again owing to operation, spiral stock stop and filter screen (cloth) are the relative motion that keeps this slip speed under impaction state all the time, so filter screen (cloth) has increased operating cost suddenly very easily because of friction is damaged by (mill), the disintegrate-quality of filtrate can not be stablized.For this reason, centrifuge manufacturer generally all has to adopt thicker tabular filter screen.Because on the electroforming process, the slit minimum that is used to filter on the tabular filter screen can only be made the wide 0.08-0.1 of reaching millimeter,, tabular filter screen contains coarse grained filtrate so can only being used for separating.Simultaneously, this spiral stock stop that does not stop to rotate makes the filtrate fragmentation very serious, can only be applicable to the not high filtrate of recovery solid particle shape requirement, thereby limit its application.
Summary of the invention
For overcoming existing conic basket type centrifuge poor filtration effect, broken serious, the wideless shortcoming of filtrate to filtrate adaptability; Adopt the contradiction that makes centrifuge structure complexity, substantial appreciation of prices behind differential attachment for overcoming existing some awl basket type, the utility model provides a kind of flat filter screen guard-blocking type of cylindro-conical basket automatic fitration centrifuge that can solve above-mentioned shortcoming and contradiction.
The technical scheme that its technical problem that solves the utility model adopts is:
The rotary drum parts of flat filter screen guard-blocking type of cylindro-conical basket automatic fitration centrifuge (being designated hereinafter simply as " centrifuge ") are made to become combining structure a---rotary drum body that cylinder barrel shaped and taper barrel are installed on the outer rim flange of a circular discoid base.In rotary drum body, be provided with the thin walled cylindrical cylindrical shell that is fixed on rotary drum circular discoid base inner edge with some screws separately---the welding body of divergent-cone wall.On the conical tube external surface of this welding body, be welded with many along equally distributed broken line shape of circumference or curved ladder retaining device.When centrifuge moves, this ladder retaining device can keep relative static with rotary drum body, promptly rotate synchronously with rotary drum body, thereby force filtrate (slag) under centrifugal action, force the broken line shape that forms along the internal conical surface of the taper barrel of ladder retaining device and rotary drum body or shaped form passage (going out) by the time constantly stopped, constantly commutating causing the pulsation jogging, thereby make filtrate (slag) holdup time in rotary drum----promptly take off the liquid time, on average prolonged more than 20 times; And make filtrate (slag) in running because of be subjected to centrifugal action in the process that the big end of taper barrel inner conical surface of rotary drum body moves because of continuous bump ladder baffle plate to the relative position that changes himself shape and each several part repeatedly, make filtrate (slag) be taken off liquid more fully.Meanwhile, slow down greatly because of the friction velocity of filtrate and rotary drum filter screen (cloth) again, prolonged the service life of filter screen (cloth), reduced operating cost, guaranteed the stability of filtrate disintegrate-quality.
In addition, novel " flat filter screen " that the long and narrow bar shaped Thin Stainless Steel sheet of settling with substantial radial again at the cylinder barrel shaped inwall of the rotary drum body of the rotary drum parts of centrifuge is formed by stacking replaces conventional Steel net (cloth) used on the existing filtering centrifuge to filter, and causes this long-term pendent difficult problem of poor filtration effect to solve existing filter screen (cloth) because of there being " fixedly filter cake "; The corresponding technological measure of " flat filter screen " being taked because of the utility model has guaranteed that this filter screen can stably block greater than, the filtering material particle that equals the 0.01--0.02 mm dia and has entered liquid again, so improved the clarity of filtrate and taken off the liquid quality, also enlarged the range of application of centrifuge.
The above-mentioned ladder retaining device that is used to delay the speed of service of filtrate in the taper barrel of rotary drum body, because of being fixed on some screws on the rotary drum circular discoid base inner edge, when making its work and rotary drum body rotate synchronously, delay the speed of service of filtrate (slag) in rotary drum body and need not cause the taper barrel of rotary drum body and spiral stock stop speed discrepancy between the two to reach, to save costliness, complicated differential attachment; Or need not add motor in addition and drive and reach this purpose---cause the centrifuge cost to descend significantly.
The straight tube two cover pay-offs that 90 of positioned vertical is spent the circular arc bend pipes or the built-in spiral feeding shaft of level is housed in semi-solid (filtrate or filter residue) import below are housed in liquid (filtrate) the import below of this centrifuge, are respectively applied for liquid filtrate and semi-solid filtrate are introduced rotary drum.Two cover pay-offs are used to connect the feeding pipe of feeding-passage, all be in the axial line position of rotary drum parts after the installation, all make have same shape, same size and in centrifuge, have same installation site, repeat to take off liquid with the filtrate (or filter residue) that adapts to different liquid contents, enlarged the range of application of centrifuge, reached a tractor serves several purposes, save the purpose that the user pays wages and reduces plant area.
The beneficial effects of the utility model are, after taking above-mentioned measure on the conventional conic basket type centrifuge, under the prerequisite that improves its filter effect, compare with the conical basket centrifuge type of existing some employing optional feature (device), single between the structure of this centrifuge, with low cost, overcome the drawback of filtrate fragmentation, enlarged the range of application of centrifuge.

The specific embodiment
In the drawings, be installed on the main axis rotation that belt pulley mat belt transmission on the main motor (2) drives main spindle box (4), rotary drum parts (6) are exactly by key connecting, are being driven by this main shaft and are rotating and carry out work.After the liquid filtrate enters from liquid-inlet (7), promptly arrive on the circular discoid base that is installed in rotary drum parts (6) and ladder retaining device rotary drum body rotation synchronously by feeding pipe (8).The ladder retaining device is by combining with the cylindrical tube of the corresponding coaxial line of shape of rotary drum body and divergent-cone wall and the roundlet conical shell welding opposite with this divergent-cone wall size extreme direction.In the outer rim of the cylindrical tube of ladder retaining device, be welded with some symmetries, equally distributed radially thin plate inwall with the cylinder barrel shaped that is supported and fixed on rotary drum body; In the outer rim of the divergent-cone wall of ladder retaining device, be welded with the rectangular broken line shape or the curved laminar baffle plate of many vertical arrangements.These baffle plates by arranging along the circumferential five equilibrium of taper seat, and guarantee the angle of friction that the angle of the section at any some place on its facade and divergent-cone wall end section all slides on baffle plate greater than filtrate (slag) along the curve of delimiting in advance on the divergent-cone wall male cone (strobilus masculinus) or broken line.A circular hole is opened at the right small end of the roundlet conical shell of ladder retaining device center, liquid filtrate (slag) by feeding pipe (8) is after from then on the hole enters the roundlet conical shell, promptly under the action of centrifugal force that causes owing to rotary drum parts (6) rotation, big end to the roundlet conical shell flies to rapidly, and be adjacent to the baseplane of rotary drum circular discoid base right-hand member and large circle surface surface within the cylinder barrel shaped of rotary drum body and go out to the right, begun the liquid that takes off of filtrate.
At the cylinder barrel shaped inwall partly of rotary drum body, radially solid matter " flat the filter screen " that is formed by stacking by a large amount of long and narrow bar shaped Thin Stainless Steel sheets.Owing on technology, taked adequate measures, guaranteed the gap uniformity between the thin slice, can stably block the particle of diameter greater than the 0.01-0.02 millimeter, and take off rotary drum body cylinder barrel shaped part whole and can not form influence in the liquid process and take off liquid " filter cake ", thereby, improve tapping rate, improved the clarity of liquid.
Under action of centrifugal force, filtrate (slag) continues to the right to go out from rotary drum body cylinder barrel shaped part inwall, then enters the taper barrel part of rotary drum body.Because the selected in advance stairstepping baffle plate or the angle of shaped form baffle plate and conic tube end section are all greater than the angle of friction between filtrate (slag) and corrosion resistant plate, so can guarantee filtrate (slag) can not be blocked in the passage that the inwall by broken line shape baffle plate or shaped form baffle plate and rotary drum body conical portion forms, so filtrate (slag) can successfully wash away to the big end of rotary drum body conical portion along above-mentioned broken line shape or curved tortuous passageway, has entered second and has taken off the liquid stage.
As everyone knows, the motion of filtrate (slag) in existing conical basket centrifuge is an even varying accelerated motion.As previously mentioned, under the situation of no any attachment device, filtrate (slag) slides into the time (promptly taking off the liquid time) of big end only in a flash from the taper barrel part small end of rotary drum body.Under the effect of ladder retaining device, can prove, the motion of filtrate (slag) then for each from initial velocity for " 0 " initial even variable accelerated motion of (divergent-cone wall small end one side) along ladder baffle plate side until knocking adjacent baffle plate " ladder " small end one side of divergent-cone wall (also), speed is reduced to " 0 " again suddenly, forms one-shot---" pulsation ".Filtrate (slag) is made up of each " pulsation " process like this in the liquid process of taking off of the taper barrel of rotary drum body part.Because each time " pulsation " speed is all very little, so filtrate (slag) has prolonged (surplus in the of about 20 times) widely from the time that taper barrel part small end slides into big end; And each time " pulsation " all can make filtrate (slag) change the shape of himself and reconfigure the relative position of arranging each several part, so filtrate (slag) is fully taken off liquid, improved and taken off the liquid effect.
The utility model adopts is fixed on ladder retaining device on the rotary drum circular discoid base right-hand member baseplane, thoroughly abandon complex structure, expensive differential attachment, also thoroughly abandoned the structural shape that adopts two motors to drive rotary drum and spiral resistance material mechanism respectively.Therefore the centrifuge cost is reduced significantly; And because of above-mentioned ladder retaining device and the rotary drum body that is used to control filtrate (slag) speed of service synchronous fully, there is not relative motion extremely, thoroughly avoided similar type in when operation, owing to helical resistive materials device and filter screen (cloth) are made the drawback that the pressure relative motion under the impaction state very easily damages filter screen (cloth) all the time.
Promptly fall voluntarily after assembling from entering the inwall of shell (14) after the big end of taper barrel part of rotary drum body tangentially flies out through the filtrate (slag) that takes off liquid, again outside bottom slag notch (15) the discharge machine via shell (14).Can settle special-purpose conveyer belt (not shown) that filter residue is spread out of and fails from this centrifuge under the slag notch (15).After filtrate flies out from rotary drum parts (6), blocked by circular rotary drum case (5) and assembled and trickle to liquid outlet (16) and outside the discharge machine.Liquid outlet (16) is located also can connect pipe or is settled passage that filtrate is drawn this machine (not shown).
This shows that the utility model still can guarantee continuously, automatically to carry out the separation of solid, liquid body under full-speed operation.
This machine has a cover screw feed mechanism in addition, is used for the liquid that takes off of semisolid filtrate (filter residue).During work, filtrate (slag) enters from semi-solid (filtrate or filter residue) import (9), nationality be installed on the support (11) and carry by the screw feeding axle (10) that reducing motor (13) drives, enter the right small end circular hole of conicle cylindrical shell of the ladder retaining device of rotary drum parts (6) again through feeding pipe (8), beginning and the above-mentioned same liquid process of taking off of liquid filtrate repeat no more here.
Hence one can see that, and this centrifuge integrates two cover feed mechanisms, and what adapted to the filtrate of different liquid contents and filter residue repeats to take off liquid, has enlarged range of application; A tractor serves several purposes has also been saved user's spending, has reduced plant area.
All parts of this centrifuge are installed on the base plate (1), and base plate is drilled with some screw holes on (1), can be directly installed on the ground.
