Description

Technical Field

[0001] The invention belongs to the technical field of material storage, and in particular relates to a steel silo with a function of preventing material compaction. Background Art

[0002] Steel silo is a large storage facility for storing various powdery, granular or small block materials. It is usually made of steel plates and has the advantages of high structural strength, good sealing performance and small footprint. It is widely used in agriculture, chemical industry, building materials, coal and other industries.

[0003] During long-term storage, materials tend to compact on the wall or bottom of the silo due to factors such as gravity, humidity changes, and temperature fluctuations. Compaction not only makes it difficult to unload materials and increase cleaning difficulties, but also affects production efficiency and even causes equipment damage.

[0004] Traditional cleaning methods and their shortcomings:

[0005] 1. Regular manual cleaning of compacted materials is time-consuming and labor-intensive, and poses safety hazards;

[0006] 2. Adding anti-caking agent is effective but the cost is high and may affect the quality of the material;

[0007] 3. Adding devices such as vibrators and airflow assistance has limited effect and high maintenance costs.

[0008] The reason why most materials become compacted due to excessive humidity is that they are not dried when they first enter the steel silo or in batches. The humidity brought by materials in different batches at different times is different. When each batch of materials falls into the steel silo, it will affect the original materials, thus becoming compacted due to gravity, humidity and temperature.

[0009] In view of the shortcomings of the above-mentioned prior art, a steel silo with the function of preventing material compaction is designed to overcome the shortcomings of the prior art. The material can be dried in advance before entering the steel silo for the first time or in batches, so as to avoid the influence of materials from different time batches on the original material. Summary of the invention

The interior of the storage barrel 12 is provided with a bulk cone 23 located below the discharge port 132. The material in the transition chamber 131 will fall onto the bulk cone 23 in the storage barrel 12 through the discharge port 132. The bulk cone 23 will guide the material to disperse and fall around, so as to avoid the material from accumulating in the middle and the impact caused by a large amount of material falling multiple times, which may cause the material in the hopper 14 to be squeezed and compacted. A motor 24 is installed on the bulk cone 23, and the output shaft of the motor 24 is connected to a rotating shaft 241 that rotates and runs through the upper part of the bulk cone 23.

The notch on the fan plate 25 that originally corresponds to the upper and lower material ports 132 of the second transition chamber 131 will rotate to the lower material port 132 corresponding to the third transition chamber 131. At this time, the external feeding pipe can guide the materials from the feed pipe conveying guide plate 26 of the feed cover 13 to the second transition chamber 131. When the second transition chamber 131 is loaded with materials, the third transition chamber 131 starts to be loaded with materials in the same manner as above. At this time, the notch on the fan plate 25 will correspond to the lower material port 132 of the first transition chamber 131.In this way, the material in the first transition chamber 131 is discharged into the storage barrel 12, and the three transition chambers 131 are intermittently discharged in this way. The transition chamber 131 is provided with a temperature sensor 221, a humidity sensor 222 and a drying group. The temperature sensor 221 and the humidity sensor 222 are used to detect whether the temperature and humidity of the material in the transition chamber 131 exceed the set value. When the fan plate 25 and the guide plate 26 jointly block the same transition chamber 131, the drying group in the transition chamber 131 can be controlled to dry the material in the transition chamber 131, so as to pre-dry each batch of materials entering the storage barrel 12, reduce humidity, and avoid new materials affecting old materials, thereby preventing materials from hardening. The upper side of the feed cover 13 is equipped with the same number of fans 10 as the transition chamber 131.

The lower part of the feed cover 13 is connected to three support plates 21 that are evenly arranged circumferentially with the feed pipe on the feed cover 13 as the center. The upper sides of two adjacent support plates 21 are connected to the feed cover 13 with a partition plate 22 perpendicular to the support plates 21. The partition plate 22 separates the two adjacent support plates 21. A transition cavity 131 is formed between the support plate 21, the partition plate 22 and the feed cover 13. The materials falling into the transition cavity 131 are guided by the guide plate 26 to be The support plate 21 is supported and separated from other transition chambers 131 by the partition plate 22. The three support plates 21 have a notch three on one side close to each other. The notch three of the support plate 21 constitutes a discharge port 132.

The built-in temperature control system of the fan 32 is used to control the temperature of the air blown by the fan 32. A conveying pipe 33 is connected between the air outlet pipe of the fan 32 and the nozzle 31. The conveying pipe 33 will spray the air blown by the fan 32 from the nozzle 31 into the transition chamber 131 to control the temperature of the material.

[0041] like Figure 3 and Figure 5As shown, it also includes two support plates 41 connected to the lower side of the fan plate 25, and a plurality of stirring frames 42 located below the notch 1 on the fan plate 25 rotate between the two support plates 41. In the present embodiment, there are three stirring frames 42, and the stirring frames 42 are rotated to break up the materials falling from the notch 1 of the fan plate 25, so as to avoid the leakage of the agglomerated materials and prevent the materials from being blocked and stuck, thereby accelerating the falling rate of the materials. A motor 2 43 is installed on one of the two support plates 41, and the output shaft of the motor 2 43 and the end of the stirring frame 42 are both connected to a turntable 44, and a convex rod portion is provided at the eccentric part of the plane of the turntable 44. A connecting rod 45 rotates between the convex rod portions at the eccentric parts of the planes of all the turntables 44. The motor 2 43 is controlled to drive the turntable 44 thereon to rotate. Under the transmission action of the connecting rod 45, the remaining turntables 44 will drive the stirring frames 42 to rotate synchronously, thereby completing the driving of the multiple stirring frames 42.

[0042] like Figure 6 and Figure 7 As shown, it also includes a bracket 51 connected to the inside of the storage barrel 12, the middle part of the bracket 51 is coaxial with the storage barrel 12, and a plurality of baffles 52 are connected to the bracket 51, which are arranged in a left-right alternating manner from top to bottom. The baffles 52 are used to provide additional vertical support for the stacked materials inside the storage barrel 12 to prevent the continuous gravity exerted by the falling materials from causing the material at the bottom of the hopper 14 to become compacted; the baffle 52 is tilted downward away from the side of the bracket 51 to ensure the normal flow of materials.

[0043] like Figure 6 , Figure 8 and Fig. 9 As shown, it also includes a rotating rod 61 rotatably arranged in the middle of the bracket 51, and the lower end of the rotating rod 61 is connected to the spiral drum 62 located inside the hopper 14, so that the rotating rod 61 drives the spiral drum 62 to rotate to utilize the effect of the spiral to transport the material inside the hopper 14 downward, thereby facilitating the discharge of the material, and a motor three 63 is installed inside the bulk cone 23, and the output shaft of the motor three 63 and the upper end of the rotating rod 61 are both connected to a gear one 64, and the two gears one 64 are meshed with each other, and the motor three 63 is controlled to drive the gear one 64 thereon to rotate and mesh with the gear one 64 on the rotating rod 61, thereby driving the rotating rod 61 to drive the spiral drum 62 to rotate.

The sliding frame 71 slides through the baffle plate 52 on the left. The lower side of the sliding frame 71 is connected to a screen frame 72 located on the inner bottom side of the hopper 14 and below the spiral drum 62. The screen frame 72 slides around the lower end of the rotating rod 61. When the external extraction pipe draws out the material in the hopper 14, the compacted material is intercepted by the screen frame 72, so that the sliding frame 71 drives the screen frame 72 to move up, and the compacted material on the screen frame 72 will be sent to the spiral drum 62, so that the spiral drum 62 can also play an extrusion and crushing effect to disperse the compacted material. The upper part of the rotating rod 61 is connected to a resistance block 73 with a C-shaped notch, and the upper part of the rotating rod 61 is connected to an inclined resistance disk 74. Initially, the lower end of the resistance disk 74 is located in the C-shaped notch of the resistance block 73. Therefore, when the motor 63 drives the rotating rod 61 to drive the spiral drum 62 to rotate, the rotating rod 61 will also drive the resistance disk 74 to rotate. In the process that the higher end of the resistance disk 74 gradually squeezes the C-shaped notch of the resistance block 73, the resistance block 73 is subjected to the force to drive the screen frame 72 to move upward through the sliding frame 71. Similarly, the gradual rotation of the resistance disk 74 will also squeeze the resistance block 73 and drive the screen frame 72 to move downward through the sliding frame 71, thereby automatically causing the screen frame 72 to reciprocate up and down.

The nozzle 83 surrounds the spiral cylinder 62, and the conveying pipe 82 runs through the storage barrel 12. The fan 81 is controlled to make the gas pass through the conveying pipe 82 and blow out from the nozzle 83 into the hopper 14, so that the material is easier to discharge and the material is prevented from being compacted due to excessive density.

[0046] like Fig.11 As shown, it also includes a gear plate 91 rotatably arranged at the lower part of the hopper 14, and the gear plate 91 is connected to a screw shaft 92 abutting against the inner side of the hopper 14. The upper end of the screw shaft 92 slides on the hopper 14, so that the gear plate 91 drives the screw shaft 92 to rotate, thereby loosening the material inside the hopper 14, and the up and down movement of the screen frame 72 can also move the material to the rotating screw shaft 92, thereby cooperating with each other to further loosen the material. The hopper 14 is equipped with a motor 93 located on the outer side of the lower part of the hopper 14, and the output shaft of the motor 93 is connected to a gear 2 94 meshing with the gear plate 91.
