Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.
As shown in fig. 1-3, the working principle of the low-crushing low-circulation crop dryer disclosed by the invention is as follows: the material to be dried enters the elevator 2 through the feeding hopper 1 and is lifted to the top of the dryer, and enters the grain inlet pipe 22 through the material distributing tee 9, light impurities are sucked into the rear fan cover 13 of the dryer through the top dust removal fan 10, and the good material is uniformly distributed into the dryer bin through the material distributing disc 21. When the materials are filled to the position of the material level alarm line in the bin, the control box 18 controls the dryer to be automatically started and converted to a drying program. The materials in the dryer bin slowly enter the discharge hopper 19 through the grain storage section 12, the drying section 14 and the grain discharge section 16, and enter the elevator 2 again under the conversion action of the discharge valve 20 to be lifted to the top for low-cycle drying. Meanwhile, the burner in the combustion chamber 3 is opened, the air is mixed in the hot air chamber 4, then the mixed air uniformly passes through the hot air pipeline 6 and uniformly passes through the grain layer of the pentagonal box to take out moisture, and the moisture is discharged out of the dryer by the main fan 15 through the rear fan cover 13 and enters the dust removal chamber, so that a complete circulating drying process is completed. Under the condition of less materials, the air-tight system 7 can be used for adjusting, so that the drying of less materials is realized.
In the above-mentioned operation process: the configuration shown in fig. 4 is the one that achieves reduced fragmentation: in the charging and drying process, a material indication arrow is lifted into a dryer bin through a lifter 2 and enters a grain inlet pipe 22 through a material distribution tee joint 9, meanwhile, a negative pressure is formed in the grain inlet pipe 22 by a top dust removal fan 10, airflow reversely flows upwards from an air inlet of the grain inlet pipe 22 and penetrates through a material layer, light impurities in the material are sucked into a pipeline through the top dust removal fan 10 and then enter a material dryer rear air cover 13, and the good material is uniformly distributed into the dryer bin through a material distribution disc 21. The grain inlet pipe 22 adopts an inclined grain pipe structure, and falls by using the self weight of the material, so that the damage of the material is avoided compared with the traditional drier which uses an auger for feeding; the top dust removal fan 10 is arranged, materials and air pass through the top dust removal fan in a countercurrent mode, light impurities, dust and the like in the materials can be removed through circulation every time, the materials are dried more uniformly, the cleanliness of the dried materials is higher, and the field operation environment is better.
The structure shown in fig. 5 is the second structure for reducing crushing: in the drying cycle process, the material is dried in the drying section 14 and slowly enters the discharging hopper 19 at a very low speed under the frequency conversion control of the grain discharging section 16. The materials enter the elevator 2 again for circular drying operation under the conversion action of the discharge valve 20. The discharging hopper is adopted for discharging, the material is discharged by the self weight of the material, and the damage of the material is avoided compared with the traditional screw conveyor for discharging after drying; the bleeder valve adopts the low-speed variable frequency to arrange the material, compares with traditional drying and has reduced lifting machine cycle number, has avoided too much to promote the broken problem that causes. Meanwhile, the drying uniformity is ensured.
The configuration shown in fig. 6 is the third configuration to achieve reduced fragmentation: in the drying cycle process, the material enters the grain discharging section after being dried, slowly rotates in the forward direction through the discharge valve 20 and falls into the discharge hopper. Compared with the traditional drier, the direction of the discharge valve is changed from a forced mode to a reverse digging mode, and the direction of the discharge valve is changed from high-speed rotation to low-speed frequency conversion control. The crushing caused in the discharging process is avoided.
The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the invention is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
