Description
The utility model relates to dryer, relates in particular to the flow-circulating type grain drying machine.
Agricultural grain-drying often will have the enough big wet amplitude of falling.Cereal falls in thermal current when wet, and except that the fraction of beginning the time, the most of the time is in the internal moisture DIFFUSION CONTROLLED stage, thereby along with the Gu Wenhui that carries out of drying course constantly rises.The too high chemical quality and the biological quality that can influence cereal of Gu Wen.In addition, there are many cereal not wish that in drying course exogenous damp is poor in the grain, excessive temperature differentials, otherwise influence its physical qualities, for example what is called " quick-fried waist " phenomenon can appear in paddy.So the first drying precipitation range can not be excessive, in order to avoid influence the grain-drying quality.
Dryer divides low temperature drying machine and hyperthermia drying machine, and the hyperthermia drying machine improves air themperature by combustion fuel, to increase its water separation capability.The hyperthermia drying machine is faster than low temperature drying machine drying rate, and it needn't rely on ambient air temperature in the dry run, so they are more flexible.The hyperthermia drying machine has two kinds.A kind of is continuous flowing type, and another kind is a batch type.Continuous flowing type be fixture, it is charging continuously, oven dry, cooling and discharging.Batch type can be fixed, also can be portable, drying operation is many batches of carrying out.Air-flow circulation (high temperature) dryer that adopts at present generally includes drier body, diesel combustion stove, centrifugal blower.Their majority is that waste gas directly is emitted on around the equipment, has polluted operating environment; The loop structure that has, feeding device is undesirable; The need that have are done circulation respectively with two typhoon machines and are sent that using of hot blast etc. is many-sided to need improved place.
The purpose of this utility model provides a kind of simple in structure, and is easy to operate, and the oven dry scope is big, the low flow-circulating type grain drying machine of oven dry cost.
The utility model is taked following measures in order to achieve the above object.It comprises drier body, diesel combustion stove, centrifugal blower, feature is that the drier body middle part is cylinder, and the bottom is a cone, and drier body top links to each other with the centrifugal blower that is placed on the top, drier body cone bottom is provided with interior circulating valve successively, central intake pipe is taken over, bottom valve.Central intake pipe is taken on the upper portion side wall and is connected to loading hopper, and is provided with charging valve, and central intake pipe is taken on the lower sides and is connected to air inlet pipe, and the drier body lower sides is provided with discharge valve.Drier body middle part sidewall is provided with annular inlet passageway, and links to each other with air inlet pipe, and air inlet pipe links to each other with the diesel combustion stove, and the drier body sidewall that annular inlet passageway joins is provided with the air inlet orifice plate.The drier body center is provided with central intake pipe, top, central intake pipe top is provided with taper shelves cap, and central intake pipe top sidewall is provided with the taper plate washer, and the central intake pipe outside is provided with the water conservancy diversion chuck, water conservancy diversion chuck lower end is provided with the taper plate washer, and central intake pipe lower end and interior circulating valve one end join.
Advantage of the present utility model:
1. simple in structure, application maintenance is convenient.
2. stream operated, this machine host circulates with gas lift, and does not have mechanical transmission device, does not therefore have mechanical fault.Cereal does not have breakage.
3. adapt to widely, this eedle is to general rich and influential family's plantation mu number design oven dry output, 1.5 tons of batch oven dry amounts, and very the cereal of small lot (hundreds of jin) carries out drying, can also be to cereal rescue property when bad climate, prebake fast.
4. dry mass is good, and percent cracked rice, germination percentage etc. meets the purchase requirement.
5. complete machine structure letter refining is easy for installation, is beneficial to mobile operating.
6. cheap, all more cheap than similar machine, the supporting condition that provides of rich and influential family's agricultural machinery is provided the purchasing power that is fit to present rural area.
7. the indoor environment cleaning is scattered with circulation time free from dust and foreign material reinforced.
Thereby this function avoids Moldy Foodstuff, and high yield is protected to receive and provided safeguard during for bad climate, also saves the threshing ground, saves the labour, reduces expenses.
Elaborate below in conjunction with accompanying drawing
Removing figure is air-flow conical ring formula grain drying machine structural representation.
Air-flow circulating grain products dryer comprises drier body, diesel combustion stove, centrifugal blower, and feature is that drier body (2) middle part is cylinder, and the bottom is a cone, and drier body top links to each other with the centrifugal blower that is placed on the top (1).Drier body cone bottom is provided with interior circulating valve (5) successively, central intake pipe is taken over (14), bottom valve (7), central intake pipe is taken on the upper portion side wall and is connected to loading hopper, and be provided with charging valve (6), central intake pipe is taken on the lower sides and is connected to air inlet pipe (10), and the drier body lower sides is provided with discharge valve (13).Drier body middle part sidewall is provided with annular inlet passageway, and link to each other with air inlet pipe, air inlet pipe links to each other with diesel combustion stove (8), the drier body sidewall that annular inlet passageway joins is provided with air inlet orifice plate (11), the drier body center is provided with central intake pipe (3), top, central intake pipe top is provided with taper shelves cap (12), central intake pipe top sidewall is provided with the taper plate washer, the central intake pipe outside is provided with water conservancy diversion chuck (4), water conservancy diversion chuck lower end is provided with the taper plate washer, and central intake pipe lower end and interior circulating valve one end join.Interior circulating valve is the detachable sleeve pipe lifting structure that is slidingly matched, and discharge valve is the detachable discharge valve, and air inlet pipe is provided with by-passing valve (9).
The drying process that this device is made up of three moving bed districts, a district is and the fluidized drying district, and wherein a1 district is for moving and the fluidized drying district, and a2 district is and flows the lifting dry section, and the b district is dynamic tempering district, the c district is a waste gas second adverse current dry section.
This device adopts a centrifugal blower to cause negative pressure in drier body, hot blast one tunnel water conservancy diversion sleeve pipe bottom in air inlet pipe is passed barrel up-hole plate cylindrical shell that the diesel combustion stove is come out enters by the sleeve pipe top walks around the awl cap, another road enters by the top through the central tube bottom and walks around a grade cap, and two-way is concentrated after waste gas is expelled to outdoor by centrifugal blower.The reinforced stage, the cereal that circulating valve is then come by loading hopper in closing can via central tube be drawn to disperse to fall in the drier body behind grade cap around; After material is filled it up with, close reinforced valve, the water conservancy diversion sleeve structure that circulation valve then is provided with in opening can be realized with the thermal current of moving bed form and the circulation stoving process of cereal and fluidized drying-tempering-waste gas and cereal counter-current drying, reach and improve the hot blast inlet temperature under the not too high prerequisite of Gu Wen, reduce delivery temperature, improve the purpose of the dry tenacity and the thermal efficiency.Central tube can promote cereal with hot and cold wind, plays the effect of reinforced, oven dry, circulating grain products.The hot blast air inlet pipe is provided with bypass valve, and central tube is taken over bottom valve is set, and all can enter cold wind, and this gives and realizes that multiple stoving process provides possibility.
