Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation Book word can be implemented according to this.

As shown in Figure 1 and Figure 2, equipment master needed for the flexible drying device of continuous drier joint that the utility model is provided Including enter grain melt pit 110, melt pit elevator 120, cleaning sieve 130, enter grain elevator 140, it is drag conveyor 150, in parallel dry Dry machine unit 200, belt conveyor 310, row's grain elevator 330, cooler 400.

Wherein, enter grain melt pit 110, melt pit elevator 120, clear up sieve 130, enter grain elevator 140, drag conveyor 150 Constitute into grain system.

Cleaning sieve 130 is cylindrical pre-cleaning screen or vibratory sieve, and it, which is acted on, is cleared up entering the grain before drying machine, is prevented Only the debris in grain blocks drying machine, flowing of the influence grain in dryer inner.

Drag conveyor 150 is installed on the top of dryer group 200 in parallel, and is set every drying machine its top feed mouthful position In respect of opening and electric gate valve 151 is installed, during drying operation, control system is by controlling the folding of electric gate valve, control Each drying machine enters grain or suspended into grain in dryer group 200 processed；The tail end of drag conveyor 150 is designed with flash mouthful 152, works as scraper plate In conveyer 150 during remaining grain, flash bucket 320 can be discharged into by flash mouthful 152, realize that wet grain is reclaimed and dry again.

In another embodiment, drying machine unit 200 in parallel can be small-sized or medium-and-large-sized continuous drier, and simultaneously It is 2 or many to join quantity；Level sensor 210 and lower level sensor 220 are installed inside drying machine grain storage section； In the present embodiment, in the drying process, when grain reaches upper level sensor 210 inside grain storage section, overhead electric gate is closed Close, stop into grain, when grain storage section inside grain drops to lower level sensor 220, overhead electric gate is opened, and is continued into grain, Dry pars infrasegmentalis and grain temperature sensor is installed, in real time cereal temperature during detection drying operation, overtemperature is then alarmed.

In another embodiment, belt conveyor 310 and the row's of the constituting grain system of row's grain elevator 330；

Wherein, the effect of belt conveyor 310 is row's grain conveying, is that reduction is small-sized continuous dry using the purpose of Belt Conveying The percentage of damage of grain during dry machine auger row grain, belt conveyor 310 is installed on the bottom of dryer group 200 in parallel, drying machine The solid food of each drying machine discharge is delivered to conveyer one end by belt conveyor 310 in group 200, into other equipment；Arrange grain The effect of elevator 330 is that the grain for discharging belt conveyor 310 is delivered to other equipment or entrucking accumulating.

In another embodiment, in addition to cooler 400, it is to carry out dried grain to force cold wind drop that it, which is acted on, Temperature, temperature is higher after the drying for grain, is unfavorable for storage, and directly storage can make the further rise of grain temperature, accelerate the quality of grain storage Ageing, and cause grain to go mouldy, wind cooling temperature lowering should be carried out to dried grain.

As shown in Figure 1 and Figure 2, a kind of course of work of the present utility model is as follows：

Drying process of the present utility model is mainly constituted by entering grain system, dryer group, row's grain system and cooler；

When operation is dried, fill process is as follows：

Wet grain to be dried is introduced into grain melt pit 110 first, and wet grain is entered by the vertical transport of melt pit elevator 120 to be cleared up Sieve 130 carries out cleaning processing, removes the impurity of size in grain, and the wet grain after cleaning enters grain elevator 140, and vertical The grain-entering mouth end of drag conveyor 150 is delivered to, wet grain is delivered to each drying in dryer group 200 by drag conveyor 150 respectively Processing is dried in machine；

Wherein, in initial stage of drying, enter grain system and enter the order of grain elevator 140 from the close-by examples to those far off according to distance, successively Wet grain is provided for every drying machine, when wet grain position reaches upper level sensor 210 in the 1st drying machine, overhead electric lock Door 151 is closed, and is stopped into grain, the 2nd drying machine starts loading, the 1st drying machine starts drying operation, the like, until Last drying machine, which is filled, in dryer group 200 starts drying operation after grain；

During drying operation, because the work pattern of drying machine in dryer group 200 is continuous drying, it need to ensure to do There is enough wet grain in dry unit 200 in each drying machine grain storage section, therefore enter grain system and also need to as every in dryer group 200 Drying machine supplements wet grain respectively, corresponding when grain reaches lower level sensor 220 in wherein one drying machine grain storage section Overhead electric gate 151 is automatically opened up, and is entered grain system and is started into grain, until grain reaches upper level sensor 210 in grain storage section, Corresponding overhead electric gate 151 is closed automatically, is stopped into grain；It can not enter drying machine when having in drag conveyor 150 During interior wet grain, then discharged by the flash mouthful 152 of the afterbody of drag conveyor 150, be discharged into flash bucket 320, reclaimed simultaneously It is again introduced into grain system；If one drying machine overhead electric gate 151 of any of which is all closed in dryer group 200, Then stop front end and enter grain system equipment, stop into grain.

Arrange grain process as follows：

Every drying machine monomer row's grain speed is controlled respectively in dryer group 200, it is ensured that grain moisture content in every drying machine And quality requirements, the solid food of discharge is unified to pass through the row's of the being delivered to grain elevator 330 of drying machine bottom belt conveyer 310.

Cooling treatment：The warm solid food discharged after drying is promoted to cooler 400 by arranging grain elevator 330 and forced Cooling treatment, the solid food after cooling is discharged from the bottom of cooler 400, you can is transported or is stored.

In another embodiment, each drying machine monomer is shared during drying operation, in dryer group 200 enters in technique The drying of wet grain and the speed change discharge of solid food in grain system and row's grain system, each drying machine monomer of complete independently；Each drying machine list Body hot-wind inlet and delay section are mounted on temperature sensor, grain after detection drying machine medium temperature and each dryer section are dried in real time There is exception in temperature, such as temperature, then automatic alarm.

In another embodiment, the discharge of solid food drives row's grain six by arranging grain motor in body under each drying machine monomer Impeller is realized, because wet grain moisture to be dried is often fluctuated, so row's grain motor realizes stepless time adjustment by VFC, i.e., Control grain stops the moisture that drying grain is wanted in dry time realization control in each drying machine so that solid food water after drying Divide stable within acceptability limit.

Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment Listed to use, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art, Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality Specific details is not limited to new and shown here as the legend with description.
