Description

Technical Field

[0001] The invention relates to the technical field of silo anti-blocking, and in particular to an anti-blocking feeding silo for storing and using sticky and wet materials. Background Art

[0002] Sticky and wet materials have the characteristics of strong adhesion, great cohesion and poor fluidity. In chemical production, the silos for storing and transporting sticky and wet materials often have wall hanging, rat holes, arching and other phenomena, making it difficult to unload materials and very easy to get blocked. Manual cleaning is difficult and risky, which seriously affects the smooth progress of production. Vibration and impact processes are often used to clear and remove blockages. The main equipment includes activated hoppers, vibratory hammers, pulse airflow blockage clearers or vibrators, air discs, pneumatic flow rods, pneumatic fluidized beds, etc.

[0003] During the operation of the silo feeding system, when there are flow obstacles such as material adhering to the silo wall (hanging on the wall), forming tubular holes (rat holes) and material bridging (arching) at the outlet, the gravity flow characteristics of the material will be significantly destroyed. This non-uniform flow state will cause periodic flow interruption in the feeding system, which is specifically manifested as intermittent idling of the unloading device, pulsating feeding of the conveying pipeline and material window period in downstream equipment, which ultimately leads to the interruption of continuous material supply in the production process.

[0004] Therefore, in order to solve the above problems, a new anti-blocking feeding silo for storing and using sticky and wet materials is proposed. Summary of the Invention

The discharge auger simultaneously triggers the inflation mechanism to supply air to the expansion airbag. This utilizes a mechanical-pneumatic composite force field to break down the material's cohesive stress, disrupting the static friction equilibrium of the blockage, preventing material from sticking to the wall, rat holes, and arching, and achieving a continuous feeding process without the need for downtime intervention. 2. This invention applies radial pressure to the material on the silo wall by inflating the expansion airbag, which in turn impacts the sliding plate and V-shaped baffle with the directional airflow from the guide hole, creating a high-frequency vibration disturbance. The tentacle-like swing of the airflow from the bifurcated air holes at the end of the expansion airbag further disrupts the static balance of the material. This dual action forces the sticky and wet material to resume shear flow, significantly improving material discharge efficiency. 3. This invention uses an annular 30° inclined feed blade at the top of the discharge auger to create a continuous, tapering pressure gradient field, driving the material to migrate along a spiral trajectory toward the axis. While the reinforcement frame enhances structural stability, the blades are evenly distributed around the circumference to form a secondary flow field, accelerating the aggregation of materials at the auger inlet, effectively solving the problem of poor feeding of highly viscous materials. 4. The inflation mechanism of the present invention adopts a double-piston seat alternating working mode. The bidirectional thread design of the driving rod realizes the up and down staggered movement of the two piston seats. The one-way airflow control of the breathable structure ensures continuous and stable air supply. A one-way valve is set between the inflation chamber and the expansion airbag to prevent gas backflow, ensuring that the air pressure acts accurately on the material accumulation area, forming a closed-loop air pressure regulation system.

[0034] Specifically, the outer wall of the driving rod 30 is provided with threads with opposite thread directions.

[0035] Specifically, the ventilation structure includes a plurality of ventilation holes 32 arranged on the piston seat 31, and a mounting bracket 33 is fixedly installed at the bottom end of the ventilation hole 32 of the piston seat 31. An extrusion block 34 is slidably connected to the inside of the ventilation hole 32, and a matching seat 35 is installed at the bottom end of the extrusion block 34.

[0036] Specifically, the bottom ends of the matching seats 35 are each provided with a ventilation groove, the top ends of the ventilation holes 32 are provided with a groove for extrusion-matching with the extrusion block 34 , and the mounting brackets 33 are arranged in a cross shape.

[0037] In this embodiment, in order to solve the problems of material adhesion (hanging on the wall), tubular retention (rat holes) and bridging (arching) of the discharge port on the inner wall of the silo body 1, reference is made to Figures 1 to 3 The specific implementation method is as follows: in the continuous material feeding process, when the discharging mechanism 6 is started, it synchronously triggers the pneumatic control unit to drive the inflation mechanism 7 to inject compressed gas into the elastic expansion mechanism 5. As the expansion mechanism 5 expands radially, its outer surface forms a dynamic contact interface with the inner wall of the silo body 1, and active compression intervention of the accumulated material is achieved by applying controllable circumferential pressure. The device can use the mechanical-pneumatic composite force field to destroy the bonding stress between materials, break up the static friction equilibrium state of the blockage body, and force the material to restore the shear flow mode, thereby ensuring the mass flow stability of the material in the conveying pipeline. In addition, the three-level linkage design of discharging drive, pneumatic execution and expansion deformation forms a spatial three-dimensional unblocking action field. The unblocking process is fully integrated into the normal feeding process without the need for shutdown, disassembly or manual intervention. The non-rotating flexible expansion body design avoids mechanical wear and adapts to complex material conditions such as high humidity and strong viscosity.

[0038] For example: How to improve the discharge stability of materials, refer to Figure 5 and Figure 6 The driving motor 18 drives the gear reducer 19 to drive the discharging auger 20 to rotate, which can stably transport the material. In order to further improve the speed of the material entering the discharging auger 20, a feeding blade 21 is provided at the top of the discharging auger 20, which can quickly transport the material to the discharging auger 20, further improving the discharging speed of the material. The setting of the reinforcement frame 22 can further improve the working stability of the feeding blade 21.

[0039] It should be noted that the feed paddle 21 adopts a 30° fluid-optimized inclination design, forming a continuous and gradually shrinking pressure gradient field during the rotation process, realizing the directional migration of materials along the spiral trajectory toward the axis of the discharge auger 20. Its annular array layout simultaneously constructs a circumferentially uniformly distributed secondary flow field, further improving the material conveying efficiency.

[0040] In this embodiment, how to clear the blockage phenomenon, refer to Figure 3 and Figure 4 The specific implementation method is as follows. As the device starts to discharge, the discharge mechanism 6 drives the inflation mechanism 7 to supply air to the expansion mechanism 5. At this time, the gas is transported to the expansion airbag 10 and the connecting elbow 11 through the mounting ring 8. At this time, the gas inside the expansion airbag 10 is increasing. Subsequently, the expansion airbag 10 expands. As the expansion airbag 10 expands, pressure is exerted on the material, destroying the equilibrium state of the material, causing the material to fall to the discharge mechanism 6 for discharge. During the discharging process, the discharge mechanism 6 will continuously squeeze the material. In the event of blockage, it will be unblocked. In the event of no blockage, the falling speed of the material can be accelerated, further improving the discharge efficiency of the device.

[0041] It should be noted that: the expansion airbag 10 and the connecting bend 11 are equidistantly provided with guide holes 15, which can continuously blow air to the sliding plate 12, and the sliding plate 12 is equidistantly provided with baffles 14. As the sliding plate 12 is continuously blown by air, the sliding plate 12 shakes under the disturbance of the baffle 14 and the directional blowing. In conjunction with the connecting soft plate 13, the material can be shaken to further improve the material unloading speed of the device, and in conjunction with the expansion mechanism 5, the material is statically destroyed to further increase the material discharge speed.

[0042] It should also be noted that: a number of air outlet holes 16 are equidistantly provided on the expansion airbag 10. As the gas inside the expansion airbag 10 increases, the gas can flow to the outside along the air outlet holes 16, and the air outlet holes 16 on the expansion airbag 10 are provided with extensions, thereby forming multiple branches (a tentacle-like structure). As the gas enters the air outlet holes 16, the airflow will drive the extension parts of the air outlet holes 16 to swing in a circular manner, thereby increasing the static damage of the material by the expansion airbag 10, so that the material will not accumulate inside the silo body 1, thereby increasing the discharge continuity of the device and further increasing the working efficiency of the device. In addition, the end of the air outlet hole 16 is set with a 30°~45° bevel cut, and the airflow produces a speed difference on both sides of the bevel cut, forming a periodic vortex.

[0043] In this embodiment, how to quickly replenish the gas to the expansion mechanism 5, refer to Figure 6-Figure 9, the specific implementation is as follows, when the device is working, the discharging auger 20 drives the driving gear 25 and the auxiliary gear 27 to rotate, and the auxiliary gear 27 drives the driving rod 30 to rotate, and as the driving rod 30 rotates, the sliding column 38 and the guide column 39 provided on the rotating frame 37 will move along the thread on the driving rod 30, and as the driving rod 30 rotates, the piston seat 31 will move linearly along the column 29 and the driving rod 30 under the guidance of the sliding column 38 and the guide column 39, and the sliding column 38 and the guide column 39 will When the piston seat 31 moves to the bottom end of the driving rod 30, it moves upward along the thread on the driving rod 30, and then repeats the above action again to compress the air, so that the air can quickly pass through the guide column 40 and the connecting seat 41 into the interior of the inflation chamber 43, thereby realizing the gas supply to the expansion mechanism 5. In order to ensure the stability of the piston seat 31 during the reciprocating motion, a number of breathable structures are equidistantly provided on the piston seat 31, which can ensure the air pressure balance inside the column 29 during the movement of the piston seat 31, thereby increasing the smoothness of the movement of the piston seat 31.

[0044] It should be noted that: a one-way valve is provided at the air path connection between the expansion mechanism 5 and the inflation mechanism 7 to avoid gas backflow and further increase the stability of the device operation. In addition, the working paths of the two inflation mechanisms 7 are in an alternating working mode, that is, when one piston seat 31 is at the top end of the driving rod 30, the other piston seat 31 is at the bottom end of the driving rod 30, which can ensure continuous and uninterrupted inflation of the inflation chamber 43, thereby ensuring the saturation of the air supply of the expansion mechanism 5 and further improving the working effect of the expansion mechanism 5.

[0045] It should also be noted that: when the piston seat 31 is pressed downward, due to the pressure, the extrusion block 34 will fit tightly against the piston seat 31, so that the piston seat 31 forms a complete piston structure to compress the air, so that the gas can be better inflated. When the piston seat 31 moves upward, the air pressure presses down the extrusion block 34 and then compresses the auxiliary spring 36, which can allow the active gas to circulate and increase the smoothness of the device during operation. In addition, a bump and a slide groove are provided between the piston seat 31 and the column 29 to further ensure the stability of the piston seat 31 during operation.

[0046] It should be noted that the connection ends between the driving gear 25 and the mounting column 17, and between the driving rod 30 and the piston seat 31 are subjected to a rotation sealing treatment.
