Description
Technical field
The utility model is related to cleaner, specifically a kind of coating dust removal device.
Background technology
Fluidized-bed coating machine is to be improved to generate by a kind of drying device that preparation is industrial, and fluid bed has back-mixing stream, piston
Stream, vibration, contact, the types such as multicompartment fluidized bed;Fluid bed main device is to divide open-type and closed circuit.Fluid bed makes
So that granulation, pellet processed, enrobing processes and drying process is once completed in a fluidized bed with nebulisation operation system and coating mode, drops
Low energy consumption.
Film coater is mainly used for the production fields such as pharmacy, food, biological products, can be various tablets, ball system, sugar
Fruit etc. packs various organic films and water-soluble film, and the usually interior plain piece being coated, piece stamen are in the closed coating drum of seed-coating machine
Interior to make continuous complicated track movement, coating medium is then sprinkled upon piece stamen surface by spray gun or dropper, while by filtering and heating
Hot wind carry out heating, drying, and penetrate piece stamen hot wind usually carry coating medium and piece stamen ingredient dust, directly row
The pollution be easy to causeing to air and environment is put, and generally coating is to carry out indoors, the indoor air of pollution is easy, to behaviour
It causes damages as personnel.
In the fluidized bed granulation or pellet processed and coating process, it should be selected according to the performance of material and in the works product quality
Select spray method.At present there are three types of bed spray methods, i.e. top spraying, tangent-type spraying and the spraying of bottom end formula.
(1) the most of products agglomerated in fluidisation of top spraying all use this law, and the particle of production is with porosity surface
It is its feature with intermittence cavity, heap density is smaller, is the effective ways for increasing insoluble drug dissolution rate, because of particle or micro-
Ball easily absorbs liquid, and disintegration is very fast, such as the drying and granulation of Chinese medicine leaching liquid.
(2) tangent-type sprays it using the centrifugal force of turntable rotation generation, the immixture of high intensity is obtained, with fluidisation
Bed drying efficiency be combined, it is higher to produce heap density, but still have a small amount of gap and cavity product, pellet hardness compared with
Greatly, non-breakable and close to spherical shape, it is the common method for preparing pellet.
(3) bottom end formula spraying is fluidized particles, pellet in the guide shell that nozzle is arranged at airflow-distribution board center
Or tablet receives adhesive or Coating Solution in guide shell.It is current most common coating of pellets mode, advantage coating efficiency
Height, pellet are not easy adhesion.Xinyi spy have been developed that inside and outside guide shell air quantity can on-line control, spraying device can Hand scarf change
Into fluid bed, the controllability of fluid bed coating of pellets is greatly improved.
Three of the above spray method is available for fluid bed and carries out particle, pellet preparation and its coating, however tablet coating is only
It is limited to bottom spraying type.The core of fluidized bed granulation coating process is the spraying system of liquid, in nearly all fluid unit
In, the effect of nozzle is dual, that is, pelletizes and be coated.Liquid sprayed under low pressure by aperture and by air-flow by mist
To change, this nozzle can generate smaller drop, be an advantage for the coating of particle or pellet, but bring therewith
It is that evaporating surface increases, droplet rapidly transforms into solids concentration during travelling forward, and viscosity also increases therewith,
If spray velocity, solution concentration and stream temperature mismate, some droplets when being contacted with particle or pellet surface,
It cannot equably sprawl, form less complete film or keep particle, pellet forming uneven, or even form adhesive or coating
Material itself is dried to particle or pellet, leads to unstable product quality or unqualified.If the evaporation of the solvent heat of atomized soln
Low, this problem will become even more serious.
It was the fine powder direct emission generated in coating process in the past or stayed in fluid bed always, was 1. directly arranged by exhaust gas
Serious pollution environment is put, 2. staying in bed can cause end product to adulterate a large amount of fine powders, cause product unqualified.
Invention content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of coating dust removal device
Problem.
To achieve the above object, the utility model provides the following technical solutions：
A kind of coating dust removal device, including device body, described device ontology is equipped with fluidized bed coating machine host, described
