Description
Technical field
It cleans field the present invention relates to material, and in particular to a kind of exclusion device, drying bed and impurity-removing method more specifically relate to
And for using real-time removing of the flow-through type with sundries in sieve plate baker operational process, raw material is in high-volume continuous drying process
Middle automatic impurity removing.
Background technique
It is general aqueous higher (45-60%) when raw material carries out drying processing using flow-through type drying equipment, viscosity compared with
Greatly, poor fluidity, sundries (clod, stone, bamboo chip, polybag etc.) is more, and new sundries can be also mixed by conveying in all swivel links,
These sundries directly affect the use of raw material.By taking distillers ' grains as an example, stone in pit seals the mud and plastic foil at cellar,
It is easy to be mixed into vinasse, in addition storage, the new sundries of transportational process are mixed into, directly affects distillers ' grains as fermented feed original
The use quality of material.All kinds of raw materials before entering baker, pass through during finished product is dried in preparation in feedstock transportation link
Special Double-layer revolving drum screen screens out part sundries, but can only screen out the sundries that partial size is more than 1.5cm, and partial size is below in 1.5cm
Sundries enters baker in company with raw material together is dried, and in drying course, raw material boiling under thermal current effect is fluidized and taken off
Water, such as sundries of stone class are difficult under the empty tower gas velocity of baker normal design since specific gravity is greater than normal raw material as former
Material equally floats in hot wind, and shows as stirring on bed board, jump, and with being carried out continuously for drying course, sundries is in bed board
Upper accumulation, covers sieve plate, influence normal raw material boiling fluidisation dehydration progress, make normal drying environment become deteriorate and
Delay production, at this point, reducing air inlet wind-warm syndrome, simultaneously by the normal drying materials in baker usually using charging is stopped in production
It after discharging, then thoroughly shuts down, arranges worker to enter and remove overstocked sundries in baker manually, clean out normal boot-strap again
Production, repeatedly.After production efficiency is low, the energy and cost of labor are big in operational process, while part sundries is with drying
Feedstuff enters next workshop section, such as break section, and will increase crushing and the failure rate of transporting equipment and disappearing for vulnerable part
Consumption.
