Description

Technical Field

[0001] This invention relates to the field of silo anti-clogging technology, and in particular to an anti-clogging feeding silo for storing sticky and wet materials. Background Technology

[0002] Sticky and wet materials are characterized by strong adhesion, high cohesion, and poor flowability. In chemical production, silos storing and transporting sticky and wet materials often experience problems such as wall adhesion, rat holes, and arching, making material unloading difficult and prone to blockage. Manual cleaning is difficult, risky, and seriously affects the smooth operation of production. Vibration and impact processes are commonly used to clear blockages. The main equipment includes activated hoppers, vibrating hammers, pulse airflow unblockers or vibrators, flow-aiding discs, pneumatic flow-aiding rods, and pneumatic fluidized beds.

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

[0004] Therefore, in response to the above problems, a new anti-clogging feeding silo is proposed for storing viscous and wet materials. Summary of the Invention

[0005] To overcome the problems existing in related technologies, the present invention provides a clog-proof feeding silo for storing viscous and wet materials. The silo can prevent material accumulation inside the silo body through the cooperation of the expansion mechanism, the discharge mechanism and the inflation mechanism, thereby further improving the discharge stability of the material.

[0006] To achieve the above objectives, the first aspect of the present invention provides a clog-resistant feeding silo for storing sticky and wet materials, comprising: a silo body for storing materials, a support frame fixedly installed at the bottom of the silo body, a protective top frame fixedly installed at the top of the silo body, and a ladder for climbing fixedly installed on one side of the silo body; and further comprising: an expansion mechanism, two expansion mechanisms arranged vertically on the inner wall of the silo body for compressing the materials inside the silo body, including an expansion airbag for compressing and loosening the materials on the inner wall of the silo body, and a sliding mechanism to increase the loosening effect of accumulated materials.

A feed blade is fixedly installed at the top of the discharge auger. A reinforcing frame is fixedly installed at the top of the feed blade and is fixedly connected to the top of the discharge auger. Discharge hoppers are symmetrically fixedly installed on both sides of the bottom of the mounting column, and shielding covers that cooperate with the discharge hoppers are symmetrically slidably connected on both sides of the bottom of the mounting column.

[0011] Furthermore, several of the feed blades are arranged in a ring, and the blades of the feed blades are inclined at 30°.

[0012] Furthermore, the inflation mechanism includes uprights symmetrically arranged on both sides of the mounting column, and the uprights are fixedly connected to both sides of the mounting column via fixing brackets. A drive gear is rotatably connected to the top of each mounting column. Fixing seats are symmetrically fixedly installed on both sides of the top of the mounting column. Auxiliary gears are rotatably connected to the interior of each of the two fixing seats. A drive rod is rotatably connected to the interior of each of the two uprights, and one end of the drive rod passes through the side wall of the upright and is fixedly connected to the auxiliary gear.

[0016] The technical solution provided by this invention may include the following beneficial effects:

[0017] 1. This invention utilizes a three-stage linkage design—driven by the discharge mechanism, supplied with air by the inflation mechanism, and expanded by the expansion mechanism—to create a three-dimensional spatial unblocking field. When the discharge auger operates, it simultaneously triggers the inflation mechanism to supply air to the expansion airbag. This mechanical-pneumatic composite force field disrupts the material's adhesive stress, breaking down the static frictional equilibrium of the blockage, preventing material from adhering to the walls, creating rat holes, and arching. This achieves a continuous feeding process without requiring machine downtime.

[0018] 2. This invention applies radial pressure to the material on the bin wall after the expanded airbag is inflated, and the directional airflow from the guide holes impacts the sliding plate and V-shaped baffle, creating high-frequency vibration disturbance. The airflow from the bifurcated air outlet at the end of the expanded airbag further disrupts the static balance of the material. This dual effect forces the sticky and wet material to resume shear flow, significantly improving the feeding efficiency.

[0019] 3. This invention constructs a continuous, gradually contracting pressure gradient field through an annular 30° inclined feed blade at the top of the discharge auger, driving the material to migrate directionally towards the axis along a spiral trajectory. While the reinforcing frame enhances structural stability, the circumferentially distributed blades form a secondary flow field, accelerating material aggregation at the auger inlet and effectively solving the problem of poor feeding of highly viscous materials.

[0020] 4. The inflation mechanism of this invention adopts a dual-piston seat alternating working mode. The bidirectional thread design of the drive rod realizes the staggered movement of the two piston seats. Combined with the one-way airflow control of the ventilated structure, it ensures a continuous and stable air supply. A one-way valve is set between the inflation chamber and the expansion airbag to prevent gas backflow and ensure that the air pressure is accurately applied to the material accumulation area, forming a closed-loop air pressure regulation system.

[0042] Specifically, the expansion mechanism 5 includes an installation ring 8 fixedly installed on the outer wall of the hopper body 1. A fixing ring 9 is fixedly installed inside the hopper body 1.

[0043] Specifically, several baffles 14 are fixedly installed at equal intervals on the outer side of several sliding plates 12, and the baffles 14 are arranged in a V shape with an included angle of 60°-80°. The expansion airbag 10 and the connecting bend 11 are respectively provided with guide holes 15 for blowing air onto the sliding plates 12 on the side near the sliding plates 12.

The output end of the drive motor 18 is fixedly connected to the input end of the gear reducer 19. A discharge auger 20 is rotatably connected inside the mounting column 17. One end of the discharge auger 20 passes through the side wall of the mounting column 17 and is fixedly connected to the output end of the gear reducer 19.

Shielding covers 24 that cooperate with the discharge hoppers 23 are symmetrically slidably connected on both sides of the bottom end of the mounting column 17.

[0046] Specifically, several of the feed blades 21 are arranged in a ring, and the blades of the feed blades 21 are inclined at 30°.

[0047] Specifically, the inflation mechanism 7 includes uprights 29 symmetrically arranged on both sides of the mounting column 17, and the uprights 29 are fixedly connected to both sides of the mounting column 17 via fixing brackets 28. A drive gear 25 is rotatably connected inside the top of the mounting column 17. Fixing seats 26 are symmetrically fixedly installed on both sides of the top of the mounting column 17. Auxiliary gears 27 are rotatably connected inside the two fixing seats 26. A drive rod 30 is rotatably connected inside the two uprights 29, and one end of the drive rod 30 passes through the side wall of the upright 29 and is fixedly connected to the auxiliary gear 27. A piston seat 31 is threaded onto the drive rod 30. Several venting structures are equidistantly installed on the piston seat 31. A rotating frame 37 is symmetrically rotatably connected inside the piston seat 31. A sliding column 38 is fixedly installed in the middle of the frame 37. Guide columns 39 are symmetrically fixedly installed on both sides of the sliding column 38, and the guide columns 39 are fixedly connected to the rotating frame 37. The sliding column 38 and the guide columns 39 are slidably connected to the drive rod 30. Several guide columns 40 are fixedly installed at equal intervals at the bottom of the column 29, and the bottom of the guide columns 40 is fixedly connected to the top of the connecting seat 41. The connecting seat 41 is fixedly connected to the bottom of the column 29. The bottom of the connecting seat 41 is fixedly connected to one end of the connecting pipe 42.

A mounting bracket 33 is fixedly installed at the bottom of the vent holes 32 of the piston seat 31. A compression block 34 is slidably connected inside the vent holes 32. A mating seat 35 is installed at the bottom of the compression block 34. An auxiliary spring 36 is installed between the mating seat 35 and the mounting bracket 33.

[0050] Specifically, the bottom of each mating seat 35 is provided with a ventilation groove, the top of each ventilation hole 32 is provided with a groove for pressing and engaging with the extrusion block 34, and the mounting bracket 33 is arranged in a cross shape.

[0051] In this embodiment, to address the blockage issues such as material adhesion (wall hanging), tubular stagnation (rat holes), and bridging (arching) at 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 supply process, when the discharge 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 hopper body 1. By applying controllable circumferential pressure, active compression intervention on the accumulated material is achieved. This device can use the mechanical-pneumatic composite force field to destroy the bonding stress between materials, disintegrate the static friction balance state of the blockage, and force the material to restore the shear flow mode, thereby ensuring the stability of the mass flow rate of the material in the conveying pipeline. In addition, the three-level linkage design of discharge drive, pneumatic execution and expansion deformation forms a spatial three-dimensional unblocking action field. The unblocking process is fully integrated into the normal material supply process, without the need for machine shutdown, disassembly or manual intervention. The non-rotating flexible expansion body design avoids mechanical wear and is suitable for complex material conditions such as high humidity and strong viscosity.

[0052] For example: How to improve the stability of material discharge, refer to... Figure 5 and Figure 6 The drive motor 18 drives the gear reducer 19 to rotate the discharge auger 20, which can stably transport materials. In order to further improve the speed at which materials enter the discharge auger 20, the top of the discharge auger 20 is provided with a feed blade 21, which can quickly transport materials to the discharge auger 20, further improving the material discharge speed. The reinforcement frame 22 can further improve the working stability of the feed blade 21.

[0053] It should be noted that the feed blade 21 adopts a 30° fluid optimization tilt angle design, which forms a continuous and gradually shrinking pressure gradient field during rotation, realizing the directional migration of materials along the spiral trajectory towards the axis of the discharge auger 20. Its annular array layout simultaneously constructs a circumferentially distributed secondary flow field, further improving the material conveying efficiency.

[0054] In this embodiment, how to unclog and remove blockages is described in reference [reference needed]. Figure 3 and Figure 4 The specific implementation method is as follows: As the device starts discharging material, the discharging mechanism 6 drives the inflation mechanism 7 to supply air to the expansion mechanism 5. At this time, the gas is delivered to the expansion airbag 10 and the connecting bend 11 through the mounting ring 8. At this time, the gas inside the expansion airbag 10 increases, and then the expansion airbag 10 expands. As the expansion airbag 10 expands, it applies pressure to the material, disrupting the material's equilibrium state, thereby causing the material to fall to the discharging mechanism 6 for discharge. During the discharge process, the discharging mechanism 6 continuously squeezes the material. If a blockage occurs, it clears the blockage. If no blockage occurs, it can accelerate the falling speed of the material, further improving the discharge efficiency of the device.

[0055] It should be noted that: the expansion airbag 10 and the connecting bend 11 are provided with guide holes 15 at equal intervals, which can continuously blow air onto the sliding plate 12. The sliding plate 12 is provided with baffles 14 at equal intervals. As the sliding plate 12 is continuously blown by air, the sliding plate 12 shakes under the disturbance of the baffles 14 and the directional air blowing. In conjunction with the connecting flexible plate 13, the material can be shaken, further improving the material feeding speed of the device. In addition, in conjunction with the expansion mechanism 5, the material is statically broken, further increasing the material discharge speed.

[0056] It should also be noted that the expansion airbag 10 is provided with several air outlets 16 at equal intervals. As more and more gas is added inside the expansion airbag 10, the gas can flow outward through the air outlets 16. The air outlets 16 on the expansion airbag 10 are provided with extensions, thus forming multiple branches (similar to tentacle-like structures). As gas enters the air outlets 16, the airflow drives the extensions of the air outlets 16 to oscillate in a circular motion, thereby increasing the static disruption of the material by the expansion airbag 10. This prevents the material from accumulating inside the hopper body 1, thereby increasing the continuity of the device's discharge and further increasing the device's working efficiency. In addition, the ends of the air outlets 16 are set with a 30°~45° bevel cut. The airflow generates a velocity difference on both sides of the bevel cut, forming a periodic vortex.

[0057] In this embodiment, how to quickly replenish the gas to the expansion mechanism 5 is described in reference [reference needed]. Figures 6-9The specific implementation method is as follows: When the device is working, the discharge auger 20 drives the drive gear 25 and the auxiliary gear 27 to rotate. The auxiliary gear 27 drives the drive rod 30 to rotate. As the drive rod 30 rotates, the sliding column 38 and the guide column 39 on the rotating frame 37 move along the thread on the drive rod 30. As the drive rod 30 rotates, the piston seat 31 moves linearly along the column 29 and the drive rod 30 under the guidance of the sliding column 38 and the guide column 39. When the piston seat 31 moves to the bottom of the drive rod 30, it moves upward along the thread on the drive rod 30. Then, the above action is repeated to compress the air, so that the air can quickly enter the interior of the air chamber 43 through the guide column 40 and the connecting seat 41, thereby supplying gas to the expansion mechanism 5. In order to ensure the stability of the piston seat 31 in the reciprocating motion, several ventilated structures are provided on the piston seat 31 at equal intervals, which can ensure the air pressure balance inside the column 29 during the movement of the piston seat 31 and increase the smoothness of the movement of the piston seat 31.

[0058] It should be noted that one-way valves are provided at the air connection points between the expansion mechanism 5 and the inflation mechanism 7 to prevent 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 of the drive rod 30, the other piston seat 31 is at the bottom of the drive rod 30, which can ensure continuous and uninterrupted inflation of the inflation chamber 43, thereby ensuring the saturation of the air supply to the expansion mechanism 5 and further improving the working effect of the expansion mechanism 5.

[0059] It should also be noted that when the piston seat 31 is pressed down, the compression block 34 will fit tightly against the piston seat 31 due to the pressure, thus forming a complete piston structure to compress the air and allow the gas to be filled better. When the piston seat 31 moves upward, the air pressure presses down on the compression block 34 and then compresses the auxiliary spring 36, which allows the moving gas to flow and increases the smoothness of the device during operation. In addition, protrusions and grooves are provided between the piston seat 31 and the column 29 to further ensure the stability of the piston seat 31 during operation.

[0060] It should be noted that the connection ends of the drive gear 25 and the mounting column 17, and the drive rod 30 and the piston seat 31 are treated with rotational sealing.
