Description
Technical field
The utility model relates to a kind of waste gas residual heats of agricultural machinery grain drying to recycle circulation and energy-saving type drying machine.
Background technique
Circulating grain dryer is outside the dryer section exhaust gas direct emission room of bottom or being discharged into dust currently on the market
Expansion chamber, the waste heat of exhaust gas cause fuel consumption big almost without recycling, and rate of drying is slow, and drying cost is high, drying machine
Energy consumption is high.
Summary of the invention
The purpose of the utility model is to overcome disadvantages mentioned above, and it is dry to provide a kind of waste gas residual heat recycling circulation and energy-saving type
The waste gas residual heat of drying machine dryer section is recycled drying grain again, because of the waste gas humidity of circulating drying machine discharge by machine
Small and temperature is applicable in, and waste heat recycling has certain utility value, can play the role of reheating, without will cause increase grain
The problems such as humidity.By drying machine dryer section two sides exclude waste heat exhaust gas, through pipeline back to drying machine middle part to grain again
Secondary heating.Drier structure is by upper flow tube, upper delay section, waste heat dryer section, lower delay section, dryer section, draining crop mechanism, pedestal branch
The compositions such as frame, air inlet, recycling air compartment, dust setting chamber, exhaust outlet, suction ventilator, downtand, motor and electric control gear.Grain
It is flowed from above to below in drying machine, burner ignition work or hot-blast stove heat supply suction ventilator starting simultaneously, in suction ventilator suction
Under effect, hot wind enters dryer section after grain layer by entering the wind angle box, is discharged into recycling air compartment by dryer section exhaust angle box two sides, to
The upper waste heat dryer section back in the middle part of drying machine, enters through waste heat dryer section flow inlet angle box two sides, and waste gas residual heat is then passed through grain
Layer is discharged to after grain heating by exhaust angle box.In usual dry paddy, environment temperature: the north is 10~-25 DEG C or so, south
Side is 5~30 DEG C, and the hot blast temperature of dry paddy is 60~65 DEG C, and the exhaust gas temperature of dryer section discharge is 30~35 DEG C, exhaust gas
Relative humidity is 45~50%, so the waste heat of exhaust gas can be returned directly to the waste heat dryer section of drying machine, reheating is
The grain of tempering cooling is recycled, it is appropriate to accelerate the evaporation of paddy moisture, the unit heat consumption of rice drying is reduced, energy-saving effect is bright
It is aobvious.This way of recycling breaches conventional thought mode and recovery method, and drying machine dryer section waste gas residual heat is recycled, and returns
Debit's formula science, compared with disposable similar model drying machine, energy saving about 20% or so improves rice drying rate
0.2%/h or so, solves that ordinary cycle formula drying machine fuel consumption is big, drying is slow, rate of drying is low, energy consumption is high, is dried into
A series of problems, such as this is high.
The technical scheme adopted by the utility model to solve the technical problem is as follows: in fig. 1 and 2, cold air is heated
For hot-air or it is hot wind, under the rotary action of negative-pressure air-suction machine (17), hot-air enters dryer section (7) through air inlet (18)
In air inlet angle box (8), carry out heat exchange with grain grain when passing through grain layer and improve grain temperature, moisture slow evaporation after grain is heated, steaming
The exhaust gas of hair is discharged into recycling air compartment (6) by dryer section exhaust angle box (19) two sides, returns back up in drying machine along recycling air compartment
The waste heat dryer section (3) in portion enters in machine through waste heat dryer section flow inlet angle box (15) two sides, and waste gas residual heat is then passed through grain layer to grain
After eating heating evaporation grain moisture content, it is discharged through exhaust angle box (4) by suction ventilator (17).Grain is thereby realized in elevator
(14) under castering action, grain constantly from upper flow tube (1) enter circulation dryer, then from downtand (10) be discharged into elevator into
During row one cycle, hot wind from dryer section (7) successively enter drying grain after, be discharged the recovered air compartment of waste gas residual heat
(6) it enters back into waste heat dryer section (3) and reheating drying is carried out to grain, is i.e. grain flows from the top to the bottom in circulating drying machine
During carrying out one cycle, after upper delay section (2) tempering, waste heat dryer section (3) are first passed through using recycling waste gas residual heat pair
It is dry that grain carries out primary heating, then after lower delay section (5) tempering, and the hot wind of drying section (7) carries out two to grain
The every circulation primary of secondary heat drying, i.e. grain is through heat drying twice, and which achieves more quick reasonable heat dryings.

Specific embodiment
The utility model optimum implementation is described with reference to the accompanying drawing.Waste gas residual heat recycles in fig. 1 and 2
Mode is embodied are as follows: hot wind through air inlet (18) enter dryer section (7) in air inlet angle box (8), pass through grain layer when with grain grain
It carries out heat exchange and improves grain temperature, the exhaust gas of moisture slow evaporation after grain is heated, evaporation is vented angle box (19) two sides by dryer section
Be discharged into recycling air compartment (6), along recycling air compartment return back up to the waste heat dryer section (3) in the middle part of drying machine, through waste heat dryer section into
Air horn box (15) two sides enter in machine, and waste gas residual heat is then passed through grain layer to grain heating evaporation grain moisture content, through being vented angle box (4)
It is discharged by suction ventilator (17).Enter the wind angle box (8) and dryer section exhaust angle box (19), waste heat dryer section air inlet angle box (15) and exhaust
Angle box (4) is right-angled intersection arrangement, and air inlet angle box (8) is identical as exhaust angle box (4) size, same layer angle box width and level
Spacing is 100-200mm, with top-bottom cross angle box spacing 120-600mm；Dryer section is vented angle box (19) and waste heat dryer section
Flow inlet angle box (15) size is identical, and same layer angle box width and horizontal space are 80-180mm, with upper and lower alternate angle box spacing
100-550mm.Arrangement and air inlet pattern of the dryer section (7) with waste heat dryer section (3) angle box can be identical mixed flow, fair current or inverse
Flow pattern formula can also be suitable, mixed flow combination pattern.Circulating drying machine hot wind flow mode is that hot wind enters from air inlet (18),
After dryer section (7) and waste heat dryer section (3) twice heat grain, become exhaust gas discharge from exhaust outlet (16), air-heater can
Being mounted on is positive pressure air feed before air inlet (18), and also mountable is negative pressure suction ventilator (17) behind exhaust outlet (16).It is remaining
Low temperature hot wind used in heated drying section (3) is that continuously grain is dried from the waste gas residual heat that dryer section (7) are recycled,
Recovery method is reasonable, and waste heat utilizes again, and energy-saving effect is significant.To guarantee grain quality, waste heat dryer section (3) and dryer section
(7) there are enough tempering spacing between, the minimum tempering spacing of lower delay section (5) should be greater than 2.4m, ensure that increasing in this way
While adding grain drying rate, the percentage of damage and Cracked Rice rate of grain are not increased, circulating drying machine divides into grain and row's grain
Not Cai Yong inclined upper flow tube (1) and downtand (10), without using traditional spiral-poker into row grain, effectively reduce grain
The percentage of damage and Cracked Rice rate of food.During cyclic drying, the dust of recycling air compartment (6) bottom dust setting chamber (11) is fallen into
And the impurity such as rice husk, according to amount of impurities number, it is primary that cleaning door (12) can be opened after completing every batch of grain drying
Cleaning among cleaning or drying process.
