Description
Technical field
Present invention relates particularly to the Solid-Liquid Separation devices of controllable solid-phase material residence time in rotary drum a kind of.
Background technology
The separation of solid-liquid phase materials mostly uses the progress of centrifuge swinging way, traditional Solid-Liquid Separation device such as Fig. 1 institutes
Show, operation principle is：Rotary drum (cone-element) main shaft drive under make high speed rotation, the material detached in conical rotor drum, according to
By the centrifugal force suffered by its own, the frictional force with the sieve on rotary drum side wall is overcome, by the small end of conical rotor drum along sieve
Surface is moved to big end, is finally automatically drained out after being collected again by material collecting tank outside discharge centrifuge, when material is being moved along rotary drum
The contained liquid phase in material is under the action of centrifuging machine power in the process, by the filter hole on sieve, passes through rotary drum, liquid phase again by
Outside casing collecting tank discharge centrifuge, to achieve the purpose that material is separated by solid-liquid separation.The type have continuously-running duty, continuously into
Material, continuous discharge, machine efficiency is high, and production capacity is big to wait objects feature, but there are the following problems in actual use：Material
The residence time is short in rotary drum, i.e., the time that material is detached is short, causes the solid-phase material temperature being discharged from material collecting tank high, solid phase
The water capacity of material is unable to get control, influences the separating effect of centrifuge, and also limit centrifugal discharging type centrifugal machine uses model
It encloses.
Invention content
In view of the above-mentioned problems, the present invention proposes a kind of Solid-Liquid Separation device, what controllable material stopped in rotary drum
Time, to control the water capacity of the solid-phase material after separation, while a brilliant degree for material will not be damaged, and make centrifugal force
The performance of conveyer centrifugal is improved, and keeps its application range more extensive.
The technical scheme is that：A kind of Solid-Liquid Separation device, including feed pipe, rotary drum, set on rotary drum big end
Striker plate, hollow shaft, the mandrel in hollow shaft, main motor and auxiliary motor；One end of the hollow shaft is fixed with rotary drum to be connected
It connects, the other end of hollow shaft is connect with main motor by V belt；One end of the mandrel is fixedly connected with striker plate, mandrel
The other end connect by V belt with auxiliary motor；Cloth bucket is equipped in the rotary drum, the discharge port of the feed pipe is set to
In cloth bucket, set on the circumference of the striker plate there are two symmetrical discharge port；The side wall of the rotary drum is equipped with filtering
Net.
When work, main motor drives hollow shaft rotation, hollow shaft that drum rotating, auxiliary motor band moving mandrel is driven to rotate, core
Axis drives striker plate rotation；Solidliquid mixture is entered by feed pipe in cloth bucket, with the rotation of rotary drum, consolidating in cloth bucket
Liquid mixture is overflowed from the surrounding of cloth bucket, and is moved from the small end of rotary drum to big end close to the side wall of rotary drum, in moving process
In, liquid is outside the filter screen discharge centrifuge on side wall in mixture, and solid reaches the striker plate of rotary drum big end in mixture
Place is discharged from the discharge outlet of striker plate.By controlling the rotating speed and rotation direction of main motor and auxiliary motor, make rotary drum and backgauge
The steering of plate is identical, and rotating speed is different, and speed discrepancy between the two indicates as follows：
Δ n=nGear-nTurn
In formula：Δ n is differential speed (r/min), nGearFor striker plate rotating speed (r/min), nTurnFor rotary drum rotating speed (r/min), sheet
Control makes striker plate rotating speed be faster than rotary drum rotating speed in invention, and Δ n is positive value.
Since in rotary drum big end, with the presence of striker plate, the material at rotary drum big end is blocked by striker plate, and centrifugation cannot be discharged
Outside machine, material is only on striker plate circumference outside two discharge port ability discharge centrifuges.It is motionless to be assumed to be rotary drum, only backgauge
Plate is rotating, and rotary drum could be discharged in solid-phase material in the local rotary drum that two discharge ports turn over, the material at other positions then by
It resting in rotary drum, such material residence time in rotary drum is longer relative to the common centrifugal discharging type centrifugal machine residence time,
Increase the time of dehydration so that the water capacity of solid phase is lower.
Meanwhile differential speed Δ n can be adjusted by main motor and auxiliary motor, then when stop of the material in rotary drum
Between can also adjust, such as：Differential speed Δ n is set as 20r/min, then the time that striker plate is gone around is (1 ÷ 20) *
60=3 seconds.It is opened on striker plate circumference there are two discharge port, then the time of material stop is 3 ÷ 2=1.5 seconds.Therefore with difference
The change material of rotating speed Δ n residence time in rotary drum is also changing, and differential speed Δ n is smaller, and residence time of material is longer,
Differential speed is bigger, and residence time of material is shorter.
In the present invention, it is preferable that the hollow shaft and mandrel is equipped with differential mechanism, and one end of the hollow shaft, which is equipped with, to be turned
The output shaft of drum belt wheel, rotary drum belt wheel and main motor is connected by V belt, and one end of the mandrel is inputted equipped with differential mechanism
The output shaft of belt wheel, differential mechanism input belt wheel and auxiliary motor is connected by V belt.It is more easily to adjust that differential mechanism, which is arranged,
Differential speed Δ n is saved, makes to generate a steadily differential speed Δ n between striker plate and rotary drum, indicate as follows：
In formula：n1For the rotating speed of rotary drum belt wheel, the rotating speed n of rotary drumTurnWith the rotating speed n of rotary drum belt wheel1It is equal；n2For differential mechanism
Input the rotating speed (r/min) of belt wheel；τ is the transmission ratio of differential mechanism.In above formula, the transmission ratio τ of differential mechanism is determined by differential mechanism, mistake
N in change formula1Or n2, so that it may easily to change the differential speed Δ n between striker plate and rotary drum.n1And n2Change be logical
Cross main motor, auxiliary motor inputs the change of frequency to control.The rotating speed of main motor and auxiliary motor can easily be changed, realized
The change of differential speed between striker plate and rotary drum.The rotating speed n of rotary drum simultaneouslyTurnWith the rotating speed n of rotary drum belt wheel1It is equal, change main electricity
The rotating speed of machine also corresponds to the rotating speed for changing rotary drum.
Further, the discharge outlet of the striker plate is equipped with material collecting tank, in order to be isolated from striker plate discharge outlet
Solid-phase material collection.
Further, the centrifuge further includes collecting tank corresponding with the filter screen, in order to from filter screen
Punish the collection of the liquid phase material separated out.
It is equipped with sluicing pipe in the rotary drum in one of the embodiments, in order to be cleaned to rotary drum.
Further, the differential speed Δ n between the rotary drum and striker plate is 3r/min-10r/min, passes through above-mentioned analysis
It is found that residence time of material is 3s-10s, so that the temperature and humidity to material controls.
The beneficial effects of the invention are as follows：By controlling rotating speed and the steering of main motor and auxiliary motor, make striker plate and rotary drum
Steering it is identical, rotating speed is different, and to control the size of the differential speed between striker plate and rotary drum, and then control material is in rotary drum
Residence time is finally reached the purpose of control water capacity of solid-phase material after separation, while brilliant of material spends also not
It can be damaged, the performance of centrifugal unloader centrifuge is made to be improved, keep its application range more extensive.
