[0046] In some embodiments, there are at least four columns 7 and at least three sets of turning blades 22.

[0047] The working principle of the technical solution provided in this application includes:

[0048] 1. Feeding stage

[0049] Lifting and conveying: Corn feed enters the elevator feed inlet 13 of the elevator through the ground conveying equipment, and the lifting motor 20 is started to drive the spiral blades to rotate.

[0050] Spiral Lifting: The spiral blades form a continuous material flow in the inclined lifting channel 12, which is conveyed upward at a rate of 20t / h (parameter of the embodiment) and evenly sprinkled into the top of the storage bin through the discharge port 14 of the elevator.

[0051] Anti-backflow design: The gap between the spiral blades and the channel is less than 2mm (preferred value), and with the variable blade diameter structure (the diameter of the bottom blades is larger than that of the top blades), a gradual compression is formed during the lifting process, which completely eliminates the material falling back.

[0052] 2. Storage stage

[0053] Three-dimensional ventilation:

[0054] Frame ventilation: Ventilation mesh 3 (0.5-1mm aperture) is installed inside the side wall frame formed by longitudinal beam 1 and transverse beam 2. External air enters through the gaps in the frame and forms laminar flow after being filtered by ventilation mesh 3.

[0055] Conical ventilation: The sidewall of the funnel-shaped discharge section 8 continues the structure of the ventilation net 3, which, together with the pores generated by the weight of the material in the bin, forms a three-dimensional airflow from top to bottom (airflow velocity 0.2-0.5m / s).

[0056] Humidity balance: When air flows through the material layer, it carries away moisture. The measured humidity gradient inside the silo is ≤5% (about 15% for traditional silos).

[0057] Dynamic material turning:

[0058] Periodic turning: The motor 20 drives the rotating shaft 21 to drive the multi-layer turning blades 22 (preferably 3 layers, spaced 1.2m apart). The blades rotate at a speed of 15-30 rpm, alternately turning the upper, middle and bottom layers of feed.

[0059] Anti-caking function: The blade adopts an obtuse-angled helical design (helix angle 45°), which generates axial and radial compound motion when turning, destroying the static friction layer of the material. Experiments show that the agglomeration rate can be reduced from 12% in traditional silos to below 3%.

[0060] 3. Discharge stage

[0061] Anti-blocking pretreatment: Start the material turning device 11 30 minutes before discharge to eliminate the bridging phenomenon above the funnel-shaped discharge section 8 by disturbing the material.

[0062] Precise material output control:

[0063] Cylinder linkage: The control cylinder pushes the piston rod 16, which drives the compartment door 18 to move horizontally along the strip hole and slide groove of the partition beam 19 (stroke 80-120mm).

[0064] Opening adjustment: The dividing beam 19 divides the discharge port into two openings. The left opening is connected to the lower end of the funnel-shaped discharge section 8. By adjusting the opening and closing ratio of the hopper door 18, the flow rate can be precisely controlled.

[0065] Anti-jamming design: The edges and tracks of the bin door 18 are lined with PTFE wear-resistant pads, which, together with the guiding effect of the strip holes, ensure smooth movement even under feed pressure.

[0066] 4. Maintenance Phase

[0067] Modular maintenance:

[0068] The damaged longitudinal beam 1 / cross beam 2 can be quickly replaced by removing the bolts of the fixing plate 6.

[0069] Maintenance platform 4 is provided with stable support through triangular reinforcing beams (inclination angle of 55°), and the platform has a load-bearing capacity of 300 kg / m. 2 Maintenance personnel can safely reach the work site via ladder 5.

[0070] Cleaning of ventilation mesh 3: Remove ventilation mesh 3 directly from the outside (snap-on connection), and use a high-pressure air gun to blow away any blockages in the pores to restore air permeability.

[0071] In summary, compared with the prior art, the advantages of the technical solution of this application include:

[0072] 1. Three-dimensional ventilation system

[0073] A three-dimensional air circulation channel is formed by installing a full-coverage ventilation net inside the longitudinal / transverse beam frame, combined with the extended ventilation structure on the side wall of the funnel-shaped discharge section. Compared with the traditional single-point ventilation mode at the top, humidity uniformity is improved, and the risk of mold growth can be reduced when combined with the material turning device.

[0074] 2. Precise and controllable material discharge mechanism

[0075] The innovative dual-door control structure uses a cylinder to drive a piston rod, which in turn links the door to the compartment. Combined with the guide holes and chutes in the partition beam, it achieves precise two-stage material control. Experimental data shows that it can accurately control the discharge flow rate error, making it particularly suitable for integration with automated batching systems.

[0076] 3. Dynamic material turning system

[0077] The suspended material turning device uses a motor fixed to the top beam to drive multiple sets of spiral blades to turn in three dimensions. Compared with the traditional fixed stirring rod, the material disturbance efficiency is improved, and the ventilation system can increase the moisture evaporation rate.

[0078] 4. High-efficiency lifting device

[0079] The inclined spiral conveying channel is integrated with the storage bin frame and adopts a variable diameter spiral blade structure. While ensuring conveying capacity, it is more energy-efficient than traditional bucket elevators and completely eliminates material backflow.

[0080] 5. Modular safety structure

[0081] The bolted frame of longitudinal / transverse beams, combined with a detachable ventilation screen, enables rapid assembly and expansion. The maintenance platform utilizes a triangular reinforced beam support structure, enhancing load-bearing capacity. Combined with a dedicated maintenance ladder, it forms a three-dimensional maintenance access, improving the efficiency of high-altitude maintenance operations.

[0082] 6. Anti-clogging material design

[0083] The funnel-shaped discharge section adopts a composite structure of frame and ventilation net, which maintains the air permeability of the side wall while ensuring the structural strength. Combined with the periodic operation of the turning device, it can effectively eliminate the phenomenon of material sticking to the bin wall.
