Description
Technical field:
The utility model belongs to a kind of grain drying machinery, specifically, particularly relates to a kind of high-effect energy-saving grain.
Background technology:
At present, the subject matter of China's grain drying equipment is that drying efficiency is lower, and power consumption is large, and after drying, grain is uneven.The drying machine functional reliability of putting on market is poor, and often occurs serious being charred particle and being mingled with a large amount of below standard wet grain in drying, causes very important loss to peasant and country.Now comparatively advanced foodstuff drying device also has the concurrent-mixed flow dryer adopting angle box-like formula, but be single admission, be subject to blast and wind quantitative limitation, based on the flowing resistance in drying layer and layer thickness increment exist 5 ~ 8 times increase progressively relation, this drying machine often efficiency is not high.
Utility model content:
The utility model object is to provide one and utilizes the top-down natural flow characteristic of grain, material is made to be in rarefaction all the time, reduce flowing resistance, reduce ventilation energy consumption, boost productivity and realize grain surface and be heated evenly, prevent grain inside from occurring the high-effect energy-saving grain of larger thermograde, lower to overcome grain drier drying efficiency in prior art, power consumption is large, the defect that after drying, grain is uneven.
The utility model realizes by the following technical solutions: a kind of high-effect energy-saving grain, comprises warehouse, lifting device, hot air apparatus, and described warehouse is connected with hot air apparatus with lifting device respectively; Wherein warehouse comprises the grain storage section, delay section and the grain discharging section that set gradually from top to down, wherein grain storage section and delay section, be provided with dryer section between delay section and grain discharging section, wherein one end of dryer section is connected with the hot air duct in hot air apparatus, and wherein hot air duct is connected with hot-blast stove by air blast; Described lifting device comprises elevator.
Further, warehouse also comprises the belt feeder be arranged on bottom warehouse.
Further, the angle box of upper and lower arrangement straggly is provided with in dryer section.
Further, the upper end of grain storage section is provided with air-permeable layer.
Further, angle box is the variable section structure of one end shutoff.
Compared with prior art, the beneficial effects of the utility model are:
(1) the middle air intake of the utility model innovative design to divide the air distribution mode of wind to both sides drying layer, is equivalent to that the thickness of drying layer is reduced 1/2, draught area increases one times;
(2) the utility model utilizes the top-down natural flow characteristic of grain, material is made to be in rarefaction all the time, reduce flowing resistance, reduce ventilation energy consumption, boost productivity and realize grain surface and be heated evenly, prevent grain inside from occurring the high-effect energy-saving grain of larger thermograde;
(3) dryer section of the utility model both sides adopts upper inferior horn box alternative form, inlet and outlet angle box is in form alternately straggly arrangement, drying medium is entered by flow inlet angle box side, the shutoff of flow inlet angle box opposite side, drying medium can only penetrate grain layer and enter exhaust angle box, then from exhaust angle box side discharge machine, drying machine is not only moved both vertically, and have horizontal movement, improve the heat transfer effect of grain at drying machine and thermal medium, make the grain moisture content of drying machine more even.

In figure: 1, elevator; 2, air-permeable layer; 3, grain storage section; 4, dryer section; 5, delay section; 6, grain discharging section; 7, hot air duct; 8, air blast; 9, hot-blast stove; 10, belt feeder; 11, angle box.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of high-effect energy-saving grain comprises warehouse, elevator 1, hot air duct 7, air blast 8, hot-blast stove 9 and belt feeder 10, and warehouse comprises grain storage section 3, dryer section 4, delay section 5, grain discharging section 6.Hot air duct 7 leads in the middle of dryer section 4, hot blast is from the middle air intake of drying tower to both sides dryer section 4 air blast, upper and lower staggered angle box 11 is provided with in dryer section 4, according to the difference of arrangement position, namely one line up as flow inlet angle box, one lines up as exhaust angle box, and angle box 11 two ends adopt and are bolted on drying machine outer wall.
Due to the heat supply continued, and the heat that grain self evaporates and produces is a lot, and the utility model adds air-permeable layer 2 in the upper end of grain storage section 3, can be good at discharging this partial heat, prevents it from being wet by grain back suction.The speed that moves down of grain is controlled by the rotating speed controlling row's grain six impeller of grain discharging section 6.
As shown in Figure 3, angle box 11 adopts the variable section structure of one end shutoff, and namely angle box 11 and horizontal line are certain angle.
As shown in Figure 4, dryer section due to the utility model both sides adopts angle box about 11 alternative form arrangement, the angle box 11 of inlet and outlet is in form alternately straggly arrangement, drying medium is entered by flow inlet angle box side, the shutoff of flow inlet angle box opposite side, drying medium can only penetrate grain layer and enter exhaust angle box, again from exhaust angle box side discharge machine, drying medium is not only moved both vertically, and have horizontal movement, improve the heat transfer effect of grain at drying machine and thermal medium, make the grain moisture content of drying machine more even.
Operation principle of the present utility model: grain drier of the present utility model is sent into by elevator until after grain reaches the regulation grain position of grain storage section 3, start to start air blast 8, belt feeder 10 and grain discharging section 6 to arrange grain and carry out drying, grain flows slowly from top to bottom, successively through grain storage section 3, dryer section 4, delay section 5, dryer section 4, grain discharging section 6, moisture content on-line automatic detection device, be transported to elevator 1 again eventually through belt feeder 10, complete primary drying circulation.The utility model innovation devise middle air intake divides air distribution mode from wind to dryer section 4 both sides, the thickness of dryer section 4 is equivalent to reduce 1/2, draught area increases one times, utilize the top-down natural flow characteristic of grain simultaneously, make material bedly to be in rarefaction all the time, reduce flowing resistance, reduce ventilation energy consumption, improve productivity ratio and realize grain surface and be heated evenly, prevent grain inside from occurring larger thermograde.
