Description
Technical field
The present invention relates to a kind of fluidized bed granulation drying equipment, particularly a kind of dust trapping chamber, spray-fluidized chamber, material container are formed a step fluidized bed granulation drying equipment of one, it is mainly used in the manufacturing of medicine, industry such as food, chemical industry is specially adapted to the preparation of Chinese medicinal granule, agricultural chemicals water dispersible granular and food dressing particle etc.
Background technology
Generally adopt wet granulator that liquid material or powder are made into particle at present.Generally must the liquid material spraying drying powder-forming is last, adopt the organic solvent or the polar solvent of high concentration to granulate as adhesive, exist operating procedure long, operating personnel are many, energy consumption height, defective such as device therefor is many, and floor space is big, and product yield is low.
Chinese patent 91230018.3 discloses a kind of spraying granulation drying equipment, and it is by the spray drying chamber, the one-step method facility for granulating that the granulation chamber is formed, and can be prepared into the particle of various granularities as requested.But its equipment spray chamber has air blast to shine into the high velocity air convection current is formed on the bed that collapses easily in the preparation of granules process, and the hot blast ring gathers shortcomings such as material easily.
Chinese patent 95240611 discloses a kind of one-step method facility for granulating, and it is with the spray drying chamber, the continuous device that the granulation chamber is formed; and can make required particle, but it is because the nozzle angle is little, and nozzle quantity is few; granulate slowly, it is big to cut required amount of binder, and distribution of particles is wide etc.
Above-mentioned two patents also have common shortcoming to be: their nozzle all is provided with on the axis of spray-fluidized chamber vertically downward, the atomized drop coverage rate of nozzle ejection is less, be difficult to effectively cover the cross section of spray-fluidized chamber, and the distribution density of atomized drop on the cross section is little, the powder material that causes the boiling shape can not fully contact with atomized drop and form the liquid bridge and condense granulating, little mist of nozzle ejection can not carry out sufficient heat exchange with high-temperature gas and be dried, thereby has influenced the efficient and the drying effect of granulating.
Summary of the invention

The specific embodiment
Referring to the described step fluidized bed granulation drying equipment of Fig. 1-3, comprise the dust trapping chamber 1 that communicates, spray-fluidized chamber 2, boiling-house 3, blast pipe (hot blast mixing chamber) 4 etc. from top to bottom.Dry powder is set at the top of dust trapping chamber captures filter bag 5, air draft switching valve 6 and filter bag electromagnetic shaker 7.Air draft opens and closes valve 6 and is connected in the induced draught system of being made up of induced duct 8, air-introduced machine 9 etc.Nozzle links to each other with compressed air hose 11; Be parallel with tube of adhesive 12 on the compressed air hose; Tube of adhesive communicates with the infusion pump (not shown) of carrying adhesive.Four covering of the fan nozzles 10 are by the hinged periphery that is distributed on columniform spray-fluidized chamber, 90% of the total coverage rate of nozzle atomization 〉=spray-fluidized chamber sectional area.In the bottom of boiling-house 3 airflow-distribution board 13 is set.The other end of blast pipe (hot blast mixing chamber) 4 connects air inlet adjustment valve 14, high efficiency particulate air filter 15, heater 16 successively, just imitates medium effeciency filter 17.
Its course of work.Air-introduced machine work, all form negative pressure in dust trapping chamber, spray-fluidized chamber, boiling-house, the blast pipe, under the suction of negative pressure, natural wind is entered by import and enters heater carry out heat exchange behind first effect medium effeciency filter, enter the air inlet adjustment valve through high efficiency particulate air filter again, enter boiling-house from airflow-distribution board after entering the hot blast mixing chamber by control valve, make the material that is contained in the airflow-distribution board top form the suspension fluidization through suction function.Compressed air is sent into nozzle and again liquid material is sent into nozzle by infusion pump through tube of adhesive, the liquid material is atomized into little vaporific attitude uniformly under compressed-air actuated peptizaiton, form moistening adhesive and contact formation liquid bridge cohesion granulating with the powder material of boiling shape in the spray-fluidized chamber, absorb a large amount of liquid materials and be dried thereby can slowly grow up by material at the state of high temperature again, high temperature makes little mist rapid draing of high-effect nozzle ejection.Dried powder is captured filter bag by dry powder and captures.The powder that captures arrives when a certain amount of, air draft opens and closes about valve switches, opening and closing valve closing as the air draft in left side makes and is in no ventilation state in the left dust trapping chamber, open the filter bag electromagnetic shaker powder that captures on the capture of the dry powder in the left dust trapping chamber filter bag is shaken off down, powder falls into the material container that is made of airflow-distribution board and boiling-house periphery.When closing left dust trapping chamber, right dust trapping chamber keeps the full open state always, and material keeps normal fluidisation motion.The particle that moves in circles constantly increases, and finishes until reaching the requirement operation of promptly granulating.
The invention provides a kind of with water, material itself or other adhesive as adhesive, integrate mixing, spraying granulation, and the equipment of powder body dressing function, one-step method realizes having liquid material granulation, powder body dressing and the fluidized drying of carrier, and can adjust grain graininess on request, to adapt to different needs.
The present invention utilizes many multi-angle nozzles of covering of the fan type that are provided with in bottom, spray-fluidized chamber, forms covering of the fan type spray adhesive, and the powder of process all covers during with fluidisation, makes the material that is stained with adhesive build bridge mutually with other material and forms particle fast.
The present invention has following characteristics: 1, granulation efficient height; 2, uniform particles; 3, yield height; 4, the product granulation time lacks, and is 2 times of original one-step palletizing; 5, dust is few; 6, energy-efficient.
Specifically, the marked improvement of this patent and good effect are:
1. the present invention collects mixing, spray-drying, granulating coated function in an equipment, it is dry directly powder material to be granulated, it is dry to granulate with heavy dose of Chinese medical concrete, and the dressing operation of bulk material, simplify technological process, increased trackability, greatly shortened job step and working time, can reduce the investment of plant and equipment, and operating personnel's quantity.
2. whole equipment is in complete air-tight state in the pelletization, and no dust from flying is conducive to the clean and tidy of operating personnel's labour protection and environment.
3. when liquid material itself is as the adhesive of granulating, solves common wet granulation and have a large amount of organic solvents and the residual problem of solvent, avoided the pollution of environment.
4. granularity adjustable extent of the present invention is wide, and narrowly distributing can be made subparticle, and the dissolution rate of particle is good, and meets compressing tablet and canned requirement.
This patent is specially adapted to Chinese medical concrete and makes the electuary particle, the water dispersible granular of agricultural chemicals, and the particle of food dressing, and its advantage is that disintegration rate is fast, the dissolution rate height.
