(1) collect air compartment and broken liquefaction paragraph; (2) is mid and dry paragraph; (3) coping reclaims paragraph. Helix of classics of stock of filter cake shape enters drier to be used at to makings device dry paragraph mid, show medicinal powder shape falls into broken liquefaction paragraph. Hot air enters collect air compartment along tangent direction, section of collect air compartment shows corkscrewed yarn gradually small, the state that the aperture between the air compartment of collect of hot air edge inside collect air compartment and broken liquefaction Duan Zhi forms high speed to rotate enters broken liquefaction paragraph. Come loose by what feeder falls lump stock suffers rotate the concussion of blade is broken reach rotate the float action of air current, between makings piece, makings piece and rotate attrition collides each other between blade, the wet share that accompanies stock evaporates, formed the grain with differ size, along with rotate the motion on gas flow direction is entered mid and dry paragraph. Because the bead diameter of grain differs, the contrail that its run is abhorrent also, be in whole and dry paragraph of dispersion inside the space, undertake be passinged adequately pledging conducting heat with hot air current, wet portion evaporates ceaselessly. Radius of orbit of bigger grain operation is bigger, wall of canister of press close to. Radius of lesser grain moving orbit is lesser. In mid and dry Duan Ding ministry setting classifications implement, bigger grain, because wet portion is large, the agglomeration phenomenon between grain fails to be eliminated in time, encounter classification implement hold back, enter broken liquefaction with bigger settling speed fall after a rise paragraph, repeat afore-mentioned processes again, imperceptible grain tells beyond the mark class along with air current implement enter reclaim paragraph, enter imperceptible pink to reclaim together along with air current device yields continuously dry the product after. Rotate craft of system of flash vaporization drier is shown 2 times like the graph.
Current, rotate the problem that flash vaporization drier exists generally is equipment one-time investment is larger, specific power consumption is bigger, and crop is opposite for lesser, and equipment is debugged expend labour. Even if whether is the dry system that already ran now also does not know in groove have drills is made. Such, economy is not good, create waste. Here has the reason of two respects, it is reasonable configuration of the system above all, such as differs in the light of different stock crop asks to undertake pledging heating up judge calculate, affirmatory quantity of heat, wind force, temperature. It is the construction that how is aimed at different stock, different system configuration to improve lead plane next. The settlement of issue of this two sides, be expected to raise yield further, improve efficiency thereby, achieve energy-saving goal. Reasonable configuration of the system, already the article is discussed, and how to improve lead plane, in reducing the spot to debug a process needless tear open decorate change, make its are in the operation below first-rate condition, have not appear in the newspaper. Because be in drier, stock grain is added rotate the rate in ascendant air current is variable, rotate air current by broken liquefaction paragraph bottom annulus is unoccupied place enter broken liquefaction paragraph, together with has again rotate of blade churn, the direction of air current and speed are not quite even also, accordingly, the can decide beforehand motion contrail that stock grain neither one secures. Current, of ministry of mid and dry Duan Ding classification implement the diameter cannot decide. And the manufacturer home of this kind of drier of nowadays, in design and production, why to plant without giving thought to stock, machine-made use classification smally implement diameter, next, after installation, look whether the yield that achieves user requirement, short of, with the change system beat, method that brings fan to deserve to compare, still short of, can tear open repeatedly only outfit, cut blindly classification greatly implement diameter. Such or big, or small the job below the condition that cannot make drier is in ideal, cost already take a lot of work, affect time of equipment put into production again, and the waste that creates the sources of energy. If pass theory to calculate what can decide different stock,classification implement diameter, it is a job that has economic value undoubtedly. 2, the athletic analysis of grain of the stock in dry process reachs analysis getting power 1. The athletic analysis of grain is in drier, enter broken liquefaction paragraph medicinal powder lump stock classics rotates the concussion collision of blade reachs what what its carry wet share to evaporate dispersedly, the agglomeration phenomenon between grain is eliminated gradually, piece, conglomerate form stock becomes differ the grain of diameter group, be rotated the action of ascendant air current, generation rotates ascendant flow. Because this process is medium, grain group microcosmic motion is very complex, , grain bead way is very small, such, assume the athletic speed photograph of the speed in circumferential direction grain and air current agrees; In radial, grain motion is left the joint action of mental efforts and drag force, the influence of oversight other element; In axial, because consider to classification implement diameter, of short duration takes no account of the axial motion of grain; And the interaction between oversight grain and fluid. Consider the radial motion of grain and circular motion only namely, inspect odd grain the athletic condition in drier. Previous12 Next
