Abstract
The utility model discloses a heat exchanger for grain drying -machine has overcome prior art, and grain stoving in -process appears drying inhomogeneously easily, still need increase treatment cost's problem. The utility model discloses a contain the fixed bolster, hot exchange pipe, air intake hood, play gas hood are equipped with a plurality of hot exchange pipe about in the fixed bolster side by side, air intake hood, go out be equipped with the inlet manifold between the gas hood, the house steward that gives vent to anger, hot exchange pipe successive layer distributes side by side, attendes the distribution of staggering of lower floor's successive layer, the first alignment of hot exchange pipe successive layer, tail alignment fixed distribution in the inlet manifold, give vent to anger between the house steward triangle -shaped of cross section for there not being the base of hot exchange pipe tail end, the pentagon of cross section for there not being the base of hot exchange pipe head end. This device is pollution -free at grain precipitation in -process, and it is even to be heated, and drying effect is good, and the moisture after grain is dried can be taken away by the hot gas flow in hollow hot exchange pipe, need not to increase follow -up processing processes.
Description
Technical field
This utility model is related to a kind of heat-exchange device of foodstuff drying device, and more particularly to one kind is used for foodstuff drying device
Heat exchanger.
Background technology
Grain is the necessary of national daily life, is epochmaking national strategy stockpile again, countries in the world pair
Grain-production deposit is all paid much attention to.The grain nature moisture of new harvesting, typically 17%～32% about, stores the safety of grain
Moisture 13% about, therefore can store it is necessary to grain precipitation is reached safe moisture if necessary to safety stock grain.
The flue gas of the vapor producing in existing grain drying equipment drying tower and air stove generation is typically no fully
Using leading to waste and the pollution to environment of heat energy, its reason is：Vapor water content 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
When using grain drying equipment, outer temperature is low, air humidity typically 50%, because traditional structure grain drying equipment is simple
It is lifted into the hot blast temperature of tower, the high hot air drying grain time long coal consumption of humidity is big, cold coal is interior when entering fire grate simultaneously
The outer temperature difference is big, maintains furnace temperature naturally to consume energy higher.
Condition of Grain-Drying Technology equipment is broadly divided into continuous way and circulation batch two big class, and the drying mode of grain mainly adopts
Convective drying method, that is, using hot-air as dried medium.In continuous way and circulation batch grain drier, grain all passes through
Self gravitation effect, is moved in drying machine from top to bottom, for dried medium, the grain of flowing is carried out drying with hot-air and makees
Industry.Circulation batch grain drier in be usually provided with for dried medium enter drying machine and flow out 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, leads to motion in drying machine for the grain to occur uneven.
In addition, the mobility of grain is relevant with the moisture content of grain, percentage of impurity.Meet rainy weather when grain harvest, then
Its moisture content and percentage of impurity will be very high, and the mobility of grain is poor, and easily in drying machine, knot arch is put up a bridge, and has a strong impact on dry product
Matter and production efficiency, or even need the another agitating device that adds to be stirred.Again, grain dry during, because difference contains
The grain distribution of the water yield is simultaneously uneven, and the motion path of grain is more fixing, leads to grain local to dry insufficient and affect
The water content of the entirety of grain, and bring difficulty to water content detection during grain heat-drying operation.
Utility model content
This utility model overcomes in prior art, and during grain heat-drying, easily appearance drying is uneven, also needs to increase
The problem of processing cost, provides the heat exchanger for foodstuff drying device that a kind of structure is simple, easy to use.
Technical solution of the present utility model is to provide a kind of heat friendship for foodstuff drying device with following structure
Parallel operation：Containing fixed support, heat-exchange tube, airscoop shroud, air leaving cover, side by side up and down in fixed support be provided with multiple heat-exchange tubes,
It is provided with inlet manifold, give vent to anger house steward, described heat-exchange tube is successively distributed side by side, and levels are successively wrong between airscoop shroud, air leaving cover
Open distribution, heat-exchange tube successively first first alignment, tail tail alignment stationary distribution in inlet manifold, give vent to anger between house steward, heat-exchange tube
The cross section of tail end is the triangle not having base, and the cross section of heat-exchange tube head end is the pentagon not having base.
The head end of described heat-exchange tube and tail end are provided with positioning tabs.The angle of the drift angle of described heat-exchange tube head end and tail end
Degree is 30≤α≤120 °, and the haunch of heat-exchange tube head end is 40 °≤α≤130 °.
Compared with prior art, this utility model has advantages below for the heat exchanger of foodstuff drying device：Grain drops
Pollution-free during water, it is heated evenly, drying effect is good, the moisture after grain heat-drying can be warm in the heat-exchange tube of hollow
Air-flow is taken away, and need not increase subsequent treatment process.Reach well dried effect, hot blast temperature need not be lifted merely, decrease energy
Consumption, improves drying quality, decreases high-temperature damage in dry run for the grain.
