Abstract
The present invention relates to centrifugal force unloading method of centrifugal machine. The rotating drum of the centrifugal machine has several groups of unloading ports with valve plate. During feeding and separating, the unloading ports are shut by their valve plates, and during unloading after finishing separation, the valve plates are removed automatically from the unloading ports and the material is unloaded via the unloading ports owing to the centrifugal force. The unloading mechanism needs no external power and has inclined planes toward the unloading port for unloading completely.
Description
Centrifuge is by the Separation of Solid and Liquid of widespread usage or concentrator in fields such as light industry, chemical industry, food, pharmacy.Press structural shape classification, have vertically and horizontal, classify, decanter type and filtering type are arranged by working method.All be in separation process the solid phase or the concentrated phase of material to be trapped in the rotary drum, liquid phase is discharged the outer working method of rotary drum at random, all exists to be trapped in the problem that solid phase in the rotary drum or concentrated phase material unload in the rotary drum.
The present invention relates to a kind of centrifugal unloader method of centrifuge.Method of the present invention is a kind of valve formula centrifugal unloader, conventional centrifugal unloader generally all is continuous operation, and is because its discharging is to carry out when high speed, of short duration from being fed to the discharge time, changeing the basket tapering has different requirements because of the different of material and rotating speed, so adaptability is relatively poor.Chinese patent (application number 95109398.3) discloses the invention of a key name for ' centrifuge that is used for the solid-liquid separation ', it also is a kind of centrifugal unloader centrifuge, the rotary drum (cone-element) of primary structure on main shaft, there being two big opening ends to be involutory, one of them is to be fixed on the axle, another can axial displacement on axle, be to move a taper drum by a hydraulic mechanism during discharging, two rotary drum (cone-element) big opening end places of being involutory are separated, and form an annular discharge port.Material is thrown away discharging along the rotary drum conical surface by centrifugal force.This invention exists following deficiency:
One, being need be by hydraulic mechanism, the opening and closing discharging opening, especially when centrifuge carries out mask work rotary drum inside along with the material, liquid increase, the drum wall will bear very big pressure, and this just must make hydraulic mechanism will keep higher pressure could guarantee that the rotary drum big opening end face place of being involutory is not separated.Not only increased energy consumption but also exist the hidden danger that dynamic sealing weares and teares, sews under the high pressure.
Two. this mode of rotary drum (cone-element) that two big opening ends are involutory only forms annular discharging opening one.For the conical surface that rotary drum is tilted to discharging opening can adapt to the centrifugal unloader of various materials, face angle will be from greatly, so just makes the part that has at rotary drum long radius place than high separating efficiency, and volume diminishes, and has reduced the service efficiency of centrifuge.
The invention provides a kind of centrifugal unloader method of centrifuge.Can solve the deficiency of foregoing invention, it need can not switch the open and close of discharging opening automatically by external actuating unit.The design of multiple tracks discharging opening has reduced the spacing of discharging opening, even adopt the conical surface of big tapering also can not reduce too many dischargeable capacity to discharging opening, moreover can also remedy by extending or increasing rotary drum.
The present invention realizes by following mode:
Have the multiple tracks discharge port on the barrel of bowl, each discharge port place all have can with the valve block of discharge port relative displacement.Reinforced at centrifuge, when separating, each discharge port is hidden by valve block, discharging opening is for closing shape.Centrifuge can feed in raw material and separate.When centrifuge carried out discharging, each discharge port valve block was removed, and discharging opening is for opening shape, and the material in the bowl throws away discharging from discharge port under centrifugal action.On the bowl barrel each transportable valve block in discharge port place be connected into one be enclosed within the rotary drum body or cylindrical shell is outer, can with the valve block group of rotary drum body relative displacement.
The mobile of valve block group is when utilizing the centrifuge difference to turn to, rotary drum or valve block group among both any one mode that is braked carry out relative angular displacement.Also can be used as power, carry out axial displacement by the pressure that liquid in the cavity between the pressure-bearing end plate of rotary drum end face and the connection of valve block group produces under centrifugal action.
On the rotary drum barrel each discharge port periphery can be oriented the face that tilts of discharging opening, be beneficial to material in the rotary drum body can be under centrifugal action unload in the rotary drum body clean.
Material in the bowl is subjected to the size of centrifugal action centrifugal force when discharge port throws away, rotational speed regulation that can be when regulating the centrifuge discharging.
Adopt the centrifuge of centrifugal unloader method of the present invention, have the common frame of conventional centrifuge, shell, bearing block, main shaft and transmission mechanism and separate mode, only different on discharge method, for realizing this centrifugal unloader method some new settings are arranged on rotary drum and shedding mechanism.
Be further described below in conjunction with accompanying drawing and example:
Accompanying drawing 1 is a kind of schematic diagram of valve block axial displacement centrifuge.
The centrifuge of valve block axial displacement, have on the cylindrical shell 1 of its rotary drum on the cylindrical shell valve 4 that has valve block 3 to connect and compose on discharging opening 2, the discharging opening 2, the cylindrical shell valve discharging opening 5 is arranged by valve block 3, be connected cylindrical shell valve 4 one ends cylindrical shell valve end plate 8, pass screw rod 9, end plate 8 outsides that end plate 8 is fixed on the rotary drum end face 7 elastomer 10 of being pressed by nut 18 arranged, the guide plate 6 of tendency discharging opening is arranged in the rotary drum body.Rotary drum end face 7 and cylindrical shell valve 4 and end plate 8 have constituted cavity A, and end plate 8 has the B chamber of a liquid storage by center axis.
During the centrifuge full-speed operation, liquid in the B chamber of liquid storage be subjected to centrifugal action to enter the A chamber and in the chamber, produce pressure with end plate 8 to pressing down, end plate 8 is when pressing down, elastomer is compressed, the cylindrical shell valve 4 that is connected with it simultaneously also moves down simultaneously, hidden the discharging opening 2 on the rotary drum body 1, centrifuge enters charging, separation phase.Enter the discharging stage when separating the end centrifuge, centrifuge decelerates at first, the pressure in A chamber descends in moderating process, compressed elastomer 10 beginning resiliences, the screen resilience that pressure drops to elastomer 10 in the A chamber can make end plate 8 travelling backwards, liquid in the A chamber begins to be back in the B chamber, after simultaneously the valve block 3 on the cylindrical shell valve 4 begins to remove from the discharging opening 2 of rotary drum body 1, material in the rotary drum body 1 is thrown away by centrifugal force from the discharging opening that begins to open 2, before decelerating to predetermined discharging speed, discharging opening is opened fully, material is thrown out of in a large number, under the guiding of discharging opening guide plate 6 up to material is unsnatched end.
The mode of this speed reducing centrifugal power discharging relatively is fit to particle rigidity and more greatly, does not allow broken crystalline solid material.Because discharging speed is lower, centrifugal force is also less, and the speed when material throws away in centrifuge, impulsive force are just little, and material just is difficult for broken.After having determined suitable discharging speed, the rotating speed in the time of can be according to the centrifuge charging, resistance and the elastomeric screen resilience that the cylindrical shell valve position is moved are set the bearing area of end plate, also can determine the opportunity of cylindrical shell valve open and close by regulating elastomeric elastic force.
Accompanying drawing 2 is centrifuge schematic diagrames of a kind of valve block angular displacement.
Have discharging on the cylindrical shell 1 of its rotary drum of centrifuge of valve block angular displacement Mouthfuls 2, discharging opening 2 inboards have by be converted into dihedral, push up to the axle center at the angle Angle bead valve block 11, angle bead valve block 11 by support ring 12, support Ring disc 13 and support annulate shaft cover 15 are connected into integrally formed valve block Group has protruding pin 16 on the rotary drum axle 14, protruding pin 16 stretches into the support ring In the groove 17 of axle sleeve 15.
Centrifuge starts running, and rotary drum begins to be rotated in the forward, and rotary drum just During to rotation, the front end face of protruding pin 16 touches and props up on the rotary drum axle 14 Frame overlaps the front end face of 15 grooves 17, angle bead valve block 11 and rotary drum Body 1 is the synchronous forward rotation under discharging opening 2 pent states. From Scheming enters charging, separation phase. Finish when separating, centrifuge advances Enter discharging during the stage, at first stop to drive and carry out of short duration to rotary drum Braking, this moment, the angle bead valve block 11 in material contains was subjected to material and its The inertia of self drives and still continues forward rotation and be subjected to temporary transient braking Cylindrical shell 1 produced angular displacement, until support casing 15 upper grooves 17 Rear end face when touching the rear end face of protruding pin 16 on the rotary drum axle 14 (should brake release simultaneously), discharging opening 2 is opened, and drives at inertia Under rotary drum body 1, the feelings that angle bead valve block 11 is opened at discharging opening 2 Continuing synchronous forward under the condition rotates. Material in the rotation is also because of centrifugal force Throw away discharging from the discharging opening 2 of opening. Owing to only depend on the driving of inertia Rotating speed will descend, when rotating speed drops to zero, if also have thing in the rotary drum Material does not unload clean, as long as rotary drum is carried out the driving of reverse directions, Discharging opening 2 is continued under the state of opening Continuous centrifugal unloader is until material is unsnatched, left alone without help mechanism moving, during counter-rotating The shutdown Brake Energy discharging opening is closed in the angular displacement of angle bead valve block. The knuckle of angle bead valve block makes two inclined-plane tilt to have played to discharging opening The effect that guide draws off. When valve block two inclined-planes are designed with through hole, The saturating liquid level of filtration that filter material has just formed centrifuge is coverd with on the valve block inclined-plane. Liquid by filter material is just discharged rotary drum from discharging opening. And cover at valve The two edges of filter material can form between valve block and the cylindrical shell again on the sheet inclined-plane Sealing strip, prevent material in the suspension at separation phase from discharging Mouth is sewed.
Can find out from the above, change as long as slightly do at existing centrifuge The moving discharge method that just can use the present invention, therefore easily manufactured, one-tenth This also is lower than other automatic discharging mode, and it is moving that it does not need to establish in addition discharging Power, simple to operate, discharging is clean, except the weaving and handware almost Can be suitable for various particles or powder material. It can be sealed fully Condition under automatic discharging, so it can be poisonous and inflammable, easy Use in the quick-fried production environment.
