Description
Technical field
The present invention relates to one-step palletizing technical field, more particularly, to a kind of ultra micro for fluidized bed granulation system
Powder capturing device.
Background technology
Fluidized bed granulation is also known as boiling granulating, and it is in boiling-like that refer to makes powder material suspend using air-flow, then sprays into bonding
Agent makes powder granulation, finally obtains dry particle, and in the process, mixing, granulation, the drying of material are completed simultaneously, therefore
Also known as one-step palletizing.
One-step palletizing system is typically by part groups such as dust catching system, spray-fluidized room, material container, control systems
Into.Traditional dust catching system is typically made up of dust-separation cloth bag and cloth bag vibrator, and wherein dust-separation cloth bag is used to collect waste gas
The solid powder of middle carrying, and solid powder is then brushed lightly out and is back to granulation by cloth bag vibrator by vibration；In the step system of patent medicine one
During grain, the particle diameter of starting supplementary material powder is generally 120 μm~150 μm, and most dust-separation cloth bag apertures are typically at 120 μm~75 μm
（Minimum aperture is 48 μm）, the collection solid powder of the dust-separation cloth bag energy more efficient, granulation efficiency is improved, meets general particle diameter
Supplementary material granulating process.
With the rise of modern superfine communication technique, the supplementary material after ultramicro grinding is handled, the overall grain of its powder
Footpath is most to be less than 45 μm, and wherein particle diameter accounts for more than 20% for 0.1 μm~10 μm, and 10 μm~30 μm account for more than 60%, for this
Supplementary material powder after micronization processes, because its particle diameter is too small, pelletized according to the dust catching device of routine, its powder
Body is easily less easily entrained by, and the solid powder carried with waste gas can be discharged by dust-separation cloth bag aperture, cause loss of material
Greatly, granulation efficiency is low, and kernel productivity is low, feed consumption, power consumption, effort, influences the performance and practical application of ultrafine powder finished product, therefore
It is necessary to improve the dust catching device in existing one-step palletizing system, so that the efficient granulation of micronizing powder can be realized.
The content of the invention
The technical problems to be solved by the invention are for present in fluidized bed granulation system capturing device in the prior art
The defects of, there is provided a kind of ultrafine powder capturing device for fluidized bed granulation system.
The purpose of the present invention is achieved by the following technical programs：
A kind of ultrafine powder capturing device for fluidized bed granulation system is provided, the top of spray-fluidized room is provided with hole 2,
Stud filter 1 is placed on the hole 2 and with fixed at the top of fluidising chamber, and the center of hole 2 is provided with nozzle 3, the other end of nozzle 3
Connect pulse of compressed air back-blowing device 4.
The aperture of the stud filter 1 is 0.1~10 μm, and effective barrier of ultramicronising dust can be achieved, and reduces material
Race leakage, improve material balance yield, improve the granulation efficiency of powder, improve kernel productivity.
Preferably, the barred body 11 of the stud filter 1 is hollow, and contains a male threaded end 12, the stud filtering
The male threaded end of device 1 is engaged with the internal thread 5 on the hole 2, so as to which stud filter 1 is connected on the hole 2.
Because the particle diameter of ultrafine powder is smaller, electrostatic adsorption force is big, is easily bonded on stud filter, and conventional bullet
The powder being bonded on stud filter effectively can not be brushed lightly out collection by spring mode of vibration, and inventor abandons conventional bullet here
Spring vibrates, and selects pulse of compressed air back-blowing device 4, blowback is carried out to stud filter using compressed air timing, so as to have
Effect reduces the dust bonding in stud.
Preferably, the nozzle 3 is vertical tubular structure, and stretches to fluidising chamber's cavity, when stud filter 1 is connected to
When on the hole 2, the nozzle 3 is located inside the barred body of stud filter 1.
During one-step palletizing, stud filter 1 is fixed on the hole 2 at the top of fluid bed, while opens compressed air arteries and veins
Back-blowing device 4 is rushed, stud filter 1 can effectively obstruct dust because its aperture is less than diameter of particle, while compressed air passes through position
The dust being bonded on stud filter is brushed lightly out in the timing of nozzle 3 inside the barred body of stud filter 1, so as to improve powder
Granulation efficiency.
As a kind of perferred technical scheme, above-mentioned ultrafine powder capturing device also includes being perpendicularly fixed at the top of fluid bed
Dividing plate 6, the dividing plate 6 is averagely separated by the shower nozzle at the top of fluidising chamber；It is highly preferred that compressed air is by being averaged point
The shower nozzle opened replaces blowback to the stud filter 1 on both sides, further reduces the powder adhesion on stud filter, improves granulation
Efficiency.
Compared with prior art, beneficial effects of the present invention：
The invention provides a kind of ultrafine powder capturing device, is mainly provided with hole, stud mistake at the top of spray-fluidized room
Filter is placed on the hole and with fixed at the top of fluidising chamber, and the hole center is provided with nozzle, and the other end connection compression of nozzle is empty
Gas pulse back-blowing device.The aperture of the stud filter is 0.1~10 μm, and effective barrier of ultramicronising dust can be achieved, subtract
The race leakage of few material, improves material balance yield；The nozzle gos deep into inside the barred body of stud filter, and compressed air passes through position
The dust being bonded on stud filter is brushed lightly out in shower nozzle timing inside stud filter barred body, so as to improve the system of powder
Grain efficiency.
