A kind of pneumatic conveying dryer
Technical field
The utility model relates to a kind of drying equipments, and in particular to a kind of pneumatic conveying dryer.
Background technique
Drying steps can be passed through in amino-acid chelate production process, hot air inlet pipe is entered with suitable spout velocity
Dry motor spindle enters material dispersion hothouse, generates that strong dispersion, blow floating rotary operation to material, then material by from
The heart, dispersion, collision, friction and by micronized, enhance mass-and heat-transfer.In the bottom of drying machine, larger wetter cluster of grains exists
Under the action of blender by mechanical blowing dissipate, moisture content it is lower, the lesser particle of granularity by swirling eddy carry secretly rise, rising
It is further dried in the process.Since gas-particle two-phase makees rotational flow, solid phase inertia is greater than gas phase, the alternate relative velocity of solid gas two
It is larger, strengthen two alternate heat and mass, so machine production intensity is high.
Its working method is usual are as follows: wet feed is added to upright pipe through feeder, and air is heated through the heater in air blower
After be blown into upright pipe, the wind speed in pipe is decided by the granular size and density of wet feed, the generally higher than sinking speed of particle, has done
Dry particle is taken out of by strong air-flow, is sent in two cyclone separators in parallel and separates, tail gas is set through bag type dust collection
It is standby to gather dust.But some substances for having peculiar smell volatile generated in process of production only use bag collection, cannot effectively go
Locate peculiar smell.Internal moisture discharges caused by being also possible to occur because of hot-spot after the material of heat drying is directly packaged bag
To surface, causes recrystallization to generate caking phenomenon, seriously affected the physical stability of product.
Therefore, a kind of new pneumatic conveying dryer is developed, not only there is urgent researching value, it may have good economic effect
Benefit and commercial application potentiality, this is exactly where the power that the utility model is accomplished and basis.
