Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and in particular to a feeding structure for a drying device. Background Technology

[0002] In the food processing industry, especially in the processing of grains (such as rice and wheat), drying is a crucial process for ensuring product quality and extending shelf life. To improve drying efficiency and reduce energy consumption, grains are usually pre-dried before entering the main drying equipment (such as drying drums) to reduce the load and processing time of subsequent drying equipment. Currently, the feeding stage from raw material storage to the drying equipment generally uses traditional conveying structures (such as screw conveyors and conveyor belts) for material transfer. However, existing feeding structures can only meet the conveying requirements and cannot simultaneously complete effective pre-drying operations. This results in the material still carrying high moisture content when entering the main drying equipment, which not only increases the energy consumption of the main drying equipment but may also lead to problems such as localized mold growth and quality degradation due to insufficient drying.

[0014] Example: Please refer to Figures 1 to 6 : This utility model proposes a feeding structure for a drying device, including: a conveying cylinder 1, a conveying cavity 1010 formed at the axial center of the conveying cylinder 1, a rotating shaft 1012 rotatably mounted at the axial center of the conveying cavity 1010, and spiral conveying blades 1013 fixedly mounted on the outer circumferential surface of the rotating shaft 1012; a set of motors 101 fixedly mounted at the axial center of the left end face of the conveying cylinder 1, the shaft end of the motors 101 passing through the conveying cavity 1010 and fixedly connected to the rotating shaft 1012; a rectangular closed frame plate 106 fixedly mounted on the front and rear sides of the outer circumference of the conveying cylinder 1, and several air inlet micro-holes 1014 connected to the conveying cavity 1010 evenly distributed in the area of ​​the inner frame of the two rectangular closed frame plates 106 on the outer circumference of the conveying cylinder 1; the two rectangular closed frame plates 106 are fixedly mounted on the front and rear sides of ... A rectangular mounting frame plate 107 is fixedly installed on the outer end face of the rectangular closed frame plate 106 adjacent to the edge. The front face of the rectangular mounting frame plate 107 has a mounting hole 1015 that penetrates the rear face at the four corners of its edge. Each of the two rectangular closed frame plates 106 has an auxiliary block 2 with a rectangular block structure. The front face of the auxiliary block 2 has a mounting hole 202 that penetrates the rear face at the four corners of its edge. The mounting hole 202 and the mounting hole 1015 are fixedly connected by bolts and nuts. A row of fans 201 is fixedly installed on the front and rear faces of the auxiliary block 2. The air supply end of the fans 201 installed on the two auxiliary blocks 2 is facing the air inlet micro-hole 1014 corresponding to its position.

[0015] A discharge pipe 108 is fixedly installed on the right side of the outer periphery of the conveying cylinder 1. The bottom end of the discharge pipe 108 has a discharge opening 109 that communicates with the conveying cavity 1010. A rectangular shell-shaped storage shell 102 is provided above the conveying cylinder 1. The bottom end of the storage shell 102 is connected to the left side of the outer periphery of the conveying cylinder 1 through a converging guide shell 103. The bottom structural dimension of the guide shell 103 is smaller than the top structural dimension of the guide shell 103. A storage groove 104 is provided on the top surface of the storage shell 102. A guide groove 105 with a similar structural outline to the guide shell 103 is provided on the bottom surface of the inner end of the storage groove 104. An inlet opening 1011 that communicates with the conveying cavity 1010 is provided on the bottom surface of the inner end of the guide groove 105.

[0016] The working principle of this embodiment: The grain to be processed (such as rice, wheat, etc.) is first put into the storage tank 104 of the storage shell 102. The guide trough 105 at the bottom of the storage tank 104 has a converging structure, which can guide the grain to fall naturally into the conveying chamber 1010 of the conveying cylinder 1 through the feed opening 1011. After the motor 101 starts, its shaft end drives the shaft 1012 in the conveying chamber 1010 to rotate, thereby synchronously driving the spiral conveying blade 1013 to rotate along the conveying chamber 1010. Through the spiral pushing action, the grain is smoothly conveyed from the left side to the right side of the conveying chamber 1010. During grain conveying, the fans 201 on the two auxiliary blocks 2 start synchronously. Since the air supply ends of the front and rear fans 201 are directly facing the air inlet micro-holes 1014 on the outer periphery of the conveying cylinder 1, and the two sets of fans 201 deliver air from the front and rear sides of the conveying cylinder 1 respectively, a convective airflow is formed that runs through the conveying cavity 1010. This convective airflow can penetrate the gaps between grain particles in the conveying process more efficiently. The airflow delivered by the front fan 201 and the airflow delivered by the rear fan 201 form a cross-circulation in the conveying cavity 1010, which not only expands the contact area between the airflow and the grain, but also accelerates the evaporation rate of moisture on the grain surface. The convection pattern can make the grain more evenly affected by the airflow, avoid moisture residue caused by insufficient airflow in some areas, further improve the pre-drying effect, and reduce the energy consumption and processing time of the subsequent drying equipment. The grain, which has been pre-dried evenly, is pushed by the spiral conveyor blades 1013 to the right side of the conveying chamber 1010, and finally discharged through the discharge opening 109 at the bottom of the discharge pipe 108, directly entering the subsequent drying equipment (such as the drying drum), thus completing the seamless connection between the feeding and drying processes.
