Description
Technical field
The utility model is related to a kind of heat-exchange device of foodstuff drying device, more particularly to a kind of to be used for foodstuff drying device
Heat exchanger.
Background technology
Grain is both the necessity of national daily life, is again epochmaking national strategy stockpile, countries in the world pair
Grain-production deposit is all paid much attention to.The grain nature moisture of new harvesting is general 17%~32% or so, stores the safety of grain
Moisture is 13% or so, so if needing safety stock grain, it is necessary to which grain precipitation is reached into safe moisture can store.
The flue gas that the vapor and hot-blast stove produced in existing grain drying equipment drying tower are produced is typically no fully
Utilize, cause the waste of heat energy and the pollution to environment, its reason is：Vapor water content is excessive, it is impossible to be used further to drying
Grain；Contain a large amount of poisonous and harmful substances in flue gas, equally cannot be used for drying grain.For China's the Northeast's Cold Winter
Using grain drying equipment when, outer temperature is low, air humidity typically 50%, because traditional structure grain drying equipment is simple
The hot blast temperature of tower is lifted into, humidity heated-air drying grain time coal consumption long high is big, while cold coal is interior when fire grate is entered
The outer temperature difference is big, maintains furnace temperature to consume energy naturally higher.
Condition of Grain-Drying Technology equipment is broadly divided into continous way and the circulation major class of batch two, and the drying mode of grain is mainly used
Convective drying method, i.e., using hot-air as dried medium.In continous way and circulation batch grain drier, grain passes through
Self gravitation effect, is moved from top to bottom in drying machine, and drying work is carried out to the grain for flowing by dried medium of hot-air
Industry.Circulate batch grain drier in be usually provided with for dried medium enter drying machine and outflow drying machine horn shape box or
The parts such as net box, these horn shape boxes or net box are fixed, can produce various resistances to the motion of grain in drying machine
Power, causes motion of the grain in drying machine to occur uneven.
In addition, the moisture content of the mobility of grain and grain, percentage of impurity are relevant.Rainy weather is met when grain harvest, then
Its moisture content and percentage of impurity will be very high, and the mobility of grain is poor, arch is tied easily in drying machine and is put up a bridge, and have a strong impact on dry product
Matter and production efficiency, or even need separately to add agitating device to be stirred.Again, grain is during drying, because difference contains
The grain distribution of water is simultaneously uneven, and the motion path of grain is more fixed, and locally drying is insufficient and influences to cause grain
The overall water content of grain, and water content detection during to grain heat-drying operation brings difficulty.
Utility model content
The utility model overcomes in the prior art, and easily appearance drying is uneven during grain heat-drying, also needs to increase
The problem of processing cost, there is provided a kind of simple structure, the heat exchanger for foodstuff drying device easy to use.
Technical solution of the present utility model is to provide a kind of heat for foodstuff drying device with following structure and hands over
Parallel operation：Containing fixed support, heat-exchange tube, airscoop shroud, air leaving cover are side by side up and down in fixed support to be provided with multiple heat-exchange tubes,
Inlet manifold, outlet house steward are provided between airscoop shroud, air leaving cover, the heat-exchange tube is successively distributed side by side, and levels are successively wrong
Distribution is opened, the heat-exchange tube near inlet manifold, outlet house steward position is bellows.
The inlet manifold is located at the center of airscoop shroud, and as the center of circle, diameter of a circle accounts for air inlet to the position with inlet manifold
/ 3rd of cover horizontal width, the heat-exchange tube in this circle scope corresponding to airscoop shroud is bellows.The heat-exchange tube
Cross section is rectangle, rhombus.One angle of drift angle of the heat-exchange tube is 30 °≤α≤45 °.
Compared with prior art, the utility model has advantages below for the heat exchanger of foodstuff drying device：Grain drops
It is pollution-free during water, it is heated evenly, drying effect is good, without increasing subsequent treatment process.Well dried effect is reached, without
Simple lifting hot blast temperature, reduces energy consumption, improves drying quality, reduces high-temperature damage of the grain in drying process.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the heat exchanger that the utility model is used for foodstuff drying device；
Fig. 2 is the cross section structure diagram that the utility model is used for A-A ' in heat exchanger Fig. 1 of foodstuff drying device.
Specific embodiment
Label 1 is fixed support in brief description of the drawings, and 2 is heat-exchange tube, and 3 is air inlet, and 4 is airscoop shroud, and 5 is total air inlet
Pipe, 6 is air leaving cover, and 7 is outlet house steward.
The heat exchanger that the utility model is used for foodstuff drying device is made into one with reference to the accompanying drawings and detailed description
Step explanation：As illustrated, containing fixed support 1, heat-exchange tube 2, airscoop shroud 4, air leaving cover 6, in fixed support 1 in the present embodiment
It is side by side up and down to be provided with multiple heat-exchange tubes 2, inlet manifold 5, outlet house steward 7 are provided between airscoop shroud 4, air leaving cover 6, the heat is handed over
Change pipe 2 to be successively distributed side by side, levels are successively in staggered distribution, be near inlet manifold 5, the heat-exchange tube 2 of the position of outlet house steward 7
Bellows.
The inlet manifold 5 be located at airscoop shroud 4 center, the position with inlet manifold 5 as the center of circle, diameter of a circle account for into
/ 3rd of the horizontal width of gas hood 4, the heat-exchange tube 2 in this circle scope corresponding to airscoop shroud 4 is bellows.This structure energy
Enough to ensure, the temperature of the heat-exchange tube 2 that temperature is high and hot gas flow velocity is fast not can be significantly hotter than other heat-exchange tubes 2, Bu Huizao
Into the cause thermal damage of grain, or cross heat bonding.
Grain by being all that elevator lifts a part, can slightly cover the heat-exchange tube 2 of Multi-layers distributing every time,
Then static heat absorption a little time, grain device is let out finally by the bottom of heat-exchange tube 2, the grain of liter high-temperature is sent to bottom
In collection device, grain in dropping process, can by obliquely to flowing air, so as to take away most moisture,
Follow-up branch successively point dries to needing dry grain.
The cross section of the heat-exchange tube 2 is rectangle, rhombus.One angle of drift angle of the heat-exchange tube 2 be 30 °≤
α≤45°。
