Description
Technical field：
The present invention relates to reversible type foodstuff drying device technical field of heat exchangers, and in particular to a kind of reversible type foodstuff drying device
Heat exchanger, it is adaptable to the foodstuff drying device of large-tonnage.
Background technology：
Three groups of domestic at present heat exchangers are that heat exchange efficiency is low, and coal consumption is big, and four groups of heat exchangers are that tail cigarette temperature is low, outdoor temperature compared with
When low, running hours heat exchanger tube easy freezing.The heat exchanger of China's foodstuff drying device has three groups or four groups for many years, but uses
There is respective shortcoming in journey, wherein three groups of heat exchangers：Advantage is that tail cigarette temperature is high, and when outdoor temperature is relatively low, heat exchanger tube is difficult
Freeze；Have the disadvantage that heat exchange efficiency is low, coal consumption is big.Four groups of heat exchangers：Advantage is that heat exchange efficiency is high, and coal consumption is small；Have the disadvantage tail cigarette temperature
Degree is low, when outdoor temperature is relatively low, running hours heat exchanger tube easy freezing；The application is a kind of reversible type foodstuff drying device heat exchange
Device, combines the advantage of two kinds of heat exchangers, adds two convertible valves, when outdoor temperature is relatively low, with three groups of heat exchangers, tail
Cigarette temperature is high, heat exchanger tube not easy freezing；When outdoor temperature is higher, with four groups of heat exchangers, tail cigarette temperature is low, and heat exchange efficiency is high, coal
Consumption is small.
The content of the invention：
It is an object of the invention to provide a kind of reversible type grain heat-drying machine heat exchanger.
Above-mentioned purpose is realized by following technical scheme：
A kind of reversible type grain heat-drying machine heat exchanger, its composition includes：In drying machine body, described drying machine body inside
Between first group of heat exchanger is installed on the right side of position, first group of described heat exchanger is connected by pipeline with second group of heat exchanger, institute
The second group of heat exchanger stated is connected by pipeline with the 3rd group of heat exchanger, and the 3rd group of described heat exchanger passes through pipeline and the 4th group
Heat exchanger is connected, and the 4th group of described heat exchanger is connected by pipeline with upper conversion valve, lower conversion valve respectively, and described is upper
Threeway is installed between conversion valve, described lower conversion valve.
It is provided with the left of described reversible type grain heat-drying machine heat exchanger, described threeway on blower fan, described blower fan
Side is provided with chimney.
There is one group of support arm, one inside described reversible type grain heat-drying machine heat exchanger, described drying machine body
The described support arm of group is placed in parallel, and top has hot-blast stove entrance on the right side of described drying machine body.
Beneficial effect：
1. the present invention is mainly a kind of reversible type grain heat-drying machine heat exchanger, the structure combines the advantage of two kinds of heat exchangers,
Two convertible valves are added, when outdoor temperature is relatively low, with three groups of heat exchangers, tail cigarette temperature is high, heat exchanger tube not easy freezing；
When outdoor temperature is higher, with four groups of heat exchangers, tail cigarette temperature is low, and heat exchange efficiency is high, and coal consumption is small.
The structure of the present invention can be widely used on the foodstuff drying device of large-tonnage, i.e. the continous way suitable for more than 100 tons
Foodstuff drying device, has the advantages that i.e. energy-conservation and ensures that heat exchanger does not freeze.
The structure that the 4th group of heat exchanger that the present invention is used is connected by pipeline with upper conversion valve, lower conversion valve respectively
Form have it is simple in construction, operate steadily, change the features such as facilitating
