The complementary grain drier of wind-heat
Technical field
The present invention relates to a kind of foodstuff preservation equipment, the complementary grain drier of promptly a kind of wind-heat.
Background technology
Grains such as corn must reach safe water content through dehydrating before warehouse-in, it is rotten just to prevent to go rotten in the storage.In the past, grain drying is mainly by natural drying, and occupied ground is big, and the time is long, loses morely, is difficult to satisfy the needs of the concentrated accumulating of grain.In order to address this problem, in recent years, people adopt grain drying tower that grain is carried out dewatering operation, have obtained effect preferably., grain drying tower need be a thermal source with coal or electric power, and it is higher to consume energy, and belongs to the high-carbon operation.In order to save the coal electric resources, the someone develops a kind of overhead natural air drying equipment, exactly grain is incorporated with in the crate of certain altitude, carries out drying by natural wind.Though this equipment does not consume the coal electricity, can only carry out batch operation, one-period is adorned once, unloads once, can not carry out continuously.And duty cycle is longer, generally needs 10-15 day just can finish one-stop operation.Particularly pack into after the grain, the position of grain is constant substantially, because the wind-force of each position differs greatly, dry degree has nothing in common with each other, and the dry uniformity is relatively poor.Because by natural wind work, when wind was little, this equipment will quit work.Thereby the scope of application is very limited, can only disperse to use for peasant household, is not suitable for large-scale grain and concentrates drying operation.At above-mentioned situation, I once invented a kind of natural air dryer of grains, added the shell of setting exactly in the outside of a plurality of compass screen surface net cages, utilized the leeway of the suitable for reading and end opening of shell, realized that inner air flows, and has strengthened the stability of wind-force., find in application process that owing to be subjected to the restriction of mounting condition and conveying capacity, this equipment can not be too high, generally can only reach about 30 meters, when wind-force was especially little up, its operation also can be subjected to certain influence.Particularly in the winter of cold, grain moisture content freezes, even there is wind also to be difficult to reach the purpose of dehydration.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can make full use of natural wind, when natural wind wind-force is not enough, can replenish wind-force by equipment, cross when low, can adjust temperature by equipment in temperature, operating efficiency height, cycle weak point, dry mass is even, but both batch operations can be worked continuously again, both be fit to working in dispersion on a small scale, be suitable for the extensive grain drying equipment of concentrating dry storage again.
Above-mentioned purpose is realized by following technical scheme: develop the complementary grain drier of a kind of wind-heat, also be a kind of all around by shell seal, the air-dry tower of upper and lower opening, the tanker that has a setting in the tower at least, the both sides box wall of tanker is made of screen cloth, the tanker outside is for connecting air channel suitable for reading, different is: a side of said tanker is provided with the nature fan housing, opposite side is provided with the benefit fan housing, the nature fan housing is to surround the case type container that is buckled in tanker one side by thin plate, have the natural wind inlet below it, between nature fan housing upper end and the tanker upper end segment distance is arranged, mending fan housing is the airtight case type container that is buckled in other side lower part of tanker that is surrounded by thin plate, be provided with wind-supplying mouth in the box, wind-supplying mouth links to each other with secondary air channel, and secondary air channel stretches out outside the air-dry tower and hair-dryer joins.During work, natural wind enters the nature fan housing from air inlet, passes tanker from discharge suitable for reading under the effect of leeway.When wind-force is not enough, starts hair-dryer and replenish wind-force to tanker by mending fan housing.When temperature was too low, hair-dryer was squeezed into tanker with hot blast.
Be provided with pressure sensor and hygrosensor in the said air-dry tower, pressure sensor and hygrosensor and automaton interrelate, and equipment such as automaton and hair-dryer, last grain machine interrelate.
Said hair-dryer and thermal source join.
Said thermal source is the firepower thermal source.
Said thermal source is an electric heat source.
Said thermal source is a solar source.
The invention has the beneficial effects as follows: both can utilize natural wind, can artificially replenish wind-force again, adjust temperature, thereby the stability of the work of guarantor becomes a kind of many regions, round-the-clock grain dehydration equipment, can be fit to disperse on a small scale batch operation, can satisfy the extensive needs of working continuously of concentrating again, and have simple in structure, cheap, economize on coal, economize on electricity, low-cost, high-efficiency characteristics, be expected to substitute existing similar type, become the visual plant of grain reserves.

Among the figure as seen: support 1, air-dry tower 2, tanker 3, last grain pipe 4, air channel 5, natural fan housing 6 is mended fan housing 7, secondary air channel 8, natural wind inlet 9, wind-supplying mouth 10, control grain roller 11, screw feeder 12.
The specific embodiment
First kind of embodiment: as shown in Figure 1, 2, this air-dry tower 2 is up to 30m, and body of the tower is airtight by shell, and support 1 is arranged under the upper and lower opening, tower, on last grain pipe 4 is arranged, be provided with the tanker 3 of a plurality of settings in the tower.In conjunction with Fig. 3 as seen, two tank walls of tanker 3 are to be made of screen cloth, and both sides can utilize the shell of air-dry tower 2 in addition, tanker 3 preferred heights 30m, and thick 10cm, slot size is not to leak grain degree of being.Grain is air channel 5 by last grain pipe 4 tanker 3 of packing between each tanker 3.Because cat head wind speed height can drive the air-flow high speed uplink in the air channel 5.In a side of tanker 3, be buckled with a box-like natural fan housing 6, the loam cake of natural fan housing 6, both sides and positive sealing have natural wind inlet 9 below.Natural wind inlet 9 is provided with switch, communicates with atmosphere when opening.The height of nature fan housing 6 is lower than the height of tanker 3, and a segment distance is arranged above.At the opposite side of tanker 3, be buckled with a box-like benefit fan housing 7.It is all airtight with the front up and down to mend fan housing 7, and the wind-supplying mouth 10 that secondary air channel 8 picks out enters to be mended in the fan housing 7, and secondary air channel 8 stretches out outside the tower and communicates with hair-dryer, and hair-dryer both can communicate with atmosphere, also can communicate with hot air source.The hot air source here can be firepower thermal source, electric power thermal source, also can be solar source, as long as can produce hot blast.During drying operation, natural wind inlet 9 is opened, and natural wind enters nature fan housing 6, and penetrates tanker 3, and under the pulling of wind-force on the tower, passes tanker 35 discharges from the air channel, takes away the moisture in the grain simultaneously, impels grain drying.When natural wind is hypodynamic, can start hair-dryer, in mending fan housing 7, replenish wind-force by secondary air channel 8.Drop to below freezingly in air themperature, grain includes water freezing, and is eager to carry out can insert hot air source to hair-dryer under the dry situation, injects hot blast in tower, to improve temperature, works on.
As shown in Figure 1, 2, below tanker 3, the grain tapping equipment is housed.This routine tapping equipment is a control grain roller 10 and a screw feeder 11, control grain roller 10 is tooth posts of the peripheral uniform groove of a tooth, can be under the drive of motor, by the rotational speed of setting, tanker 3 interior grains through super-dry are ejected substantially sequentially, give following screw feeder 11, send by screw feeder 11 again.Because the rotating speed of control grain roller 10 and screw feeder 11 can be according to the degree of drying regulation and control of grain in the tower, grain in the tanker 3 can slowly move down successively, finish dehydration in the time of at the bottom of arriving tower, thereby realize working continuously, the suffered drying condition of grain is more or less the same, thereby dry degree also compares homogeneous.
