Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology and relates to a material silo device. Background Technology

[0002] A silo is a container or structure used to store and temporarily hold bulk materials (such as powder, granular, or lumpy materials). It typically has an inlet, an outlet, and storage space, and the material is fed in and out by gravity or mechanical means.

[0003] However, when the material stored inside the silo is in powder form, it is very easy for the powder to adhere to the inner wall and conical parts of the silo during the conveying process due to factors such as electrostatic adsorption and material stickiness. After a long period of accumulation, it can not only lead to a reduction in the effective volume of the silo and an increase in the amount of residual material, but may also cause agglomeration and caking, which can further cause serious problems such as poor material conveying, unstable output, or even blockage of the discharge port, affecting the continuity of production and normal operation of equipment, while increasing the cost of manual cleaning and the risk of material loss. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Example 1

[0026] like Figures 1-5 As shown, a silo device includes a silo shell 1, with support legs 11 fixedly connected to each of the four corners of the silo shell 1, two sets of feed inlets 12 installed on the top of the silo shell 1, wall cleaning components provided on all four sides of the silo shell 1, a conveying component provided at the bottom of the silo shell 1, and a crushing component provided at the top of the silo shell 1.

[0027] The wall cleaning assembly includes a first nut 2, a second nut 21, an elastic cover 22, a threaded rod 23, an air inlet 24, and multiple sets of exhaust ports 25. The first nut 2 is fixed to the inner sidewalls of the four sides of the hopper housing 1, the second nut 21 is fixed to the outer sidewalls of the four sides of the hopper housing 1, the threaded rod 23 is threaded to the middle of the first nut 2 and the second nut 21, the elastic cover 22 is fixed to one end of the threaded rod 23, the air inlet 24 is opened in the middle of the threaded rod 23, and multiple exhaust ports 25 are opened at the end of the threaded rod 23 near the elastic cover 22.

[0028] The material conveying assembly includes a material conveying bin 3, a threaded conveying motor 31, a screw conveying rod 32, and a discharge port 33. The material conveying bin 3 is installed at the bottom of the bin housing 1, and a slot is provided at the top of the material conveying bin 3. The threaded conveying motor 31 is installed at one end of the material conveying bin 3, the screw conveying rod 32 is installed at the output end of the threaded conveying motor 31, and the discharge port 33 is located at the end of the material conveying bin 3 away from the threaded conveying motor 31.

[0029] During operation, materials can be conveyed into the hopper housing 1 through the feed inlet 12. The support legs 11 can support the hopper housing 1 to keep it away from the ground. At the same time, one end of the threaded rod 23 is connected to a compressor.

[0030] When it is necessary to convey the powdered material stored inside the silo shell 1, the screw conveyor motor 31 can be driven to drive the screw conveyor rod 32 to rotate in the middle of the silo 3. The material will slide into the silo 3 through the slot at the top of the silo 3. At this time, the material can be conveyed by the rotation of the screw conveyor rod 32, so that the material is discharged from the silo shell 1 through the discharge port 33.

[0031] Meanwhile, when the threaded conveyor motor 31 is working, it can drive the compressor connected to the end of the threaded rod 23 to work. When the compressor is working, it will generate compressed air, which will be discharged into the threaded rod 23 through the air inlet 24 and finally discharged through the exhaust port 25. At this time, the compressed air will flow into the closed space formed by the elastic cover 22 and the hopper shell 1. When the compressed air reaches the load, it will drive the elastic cover 22 to deform under pressure, which will cause the elastic cover 22 to bounce at a high frequency on the inner wall of the hopper shell 1, causing the hopper shell 1 to vibrate and shake off the powdery material attached to the inner wall of the hopper shell 1.

[0032] This step, through the cooperation of the wall cleaning component and the conveying component, uses external force to break the adhesion between the powdered material and the inner wall of the silo shell 1, allowing the material adhering to the inner wall of the silo shell 1 to effectively detach and flow into the mainstream material flow. This reduces the amount of powdered material remaining on the inner wall of the silo shell 1, avoiding problems such as agglomeration and deterioration caused by long-term material accumulation. At the same time, continuous wall cleaning maintains the unobstructed flow of the conveying channel, reducing the risk of equipment downtime due to material bridging or blockage. In addition, it reduces the frequency and labor intensity of manual cleaning, effectively extending the service life of the silo shell 1 and the conveying system while improving conveying efficiency and material utilization, and improving the stable operation of the overall process.

[0033] Example 2

[0034] like Figure 1 , Figure 2 and Figure 6 As shown, the crushing assembly includes a servo motor 4, a rotating shaft 41, a support block 42, and two sets of support rods 43. The servo motor 4 is installed on one side of the top of the hopper housing 1. The rotating shaft 41 is installed at the output end of the servo motor 4, and the middle part of the rotating shaft 41 is rotatably connected to the middle of the two sets of feed inlets 12. The support block 42 is fixed to the top of the hopper housing 1 on the side away from the servo motor 4, and the end of the rotating shaft 41 away from the servo motor 4 is rotatably connected to the middle of the support block 42. The two support rods 43 are respectively fixed to the inner walls on both sides of the two sets of feed inlets 12.

[0035] The crushing assembly also includes two sets of hollow bearing sleeves 5, two sets of first bevel gears 51, two sets of driven shafts 52, and two sets of second bevel gears 53. The two first bevel gears 51 are respectively fixed to the close ends of the two sets of support rods 43. The two first bevel gears 51 are respectively fixed to the middle of the rotating shaft 41. The two driven shafts 52 are respectively rotatably connected to the middle of the two sets of hollow bearing sleeves 5. The two second bevel gears 53 are respectively fixed to the bottom of the two sets of driven shafts 52, and the two sets of second bevel gears 53 mesh with the two sets of first bevel gears 51 respectively.

[0036] The crushing assembly also includes multiple sets of blades 6, which are respectively located in the middle of the two sets of driven shafts 52.

[0037] During operation, when powdery materials are conveyed into the hopper housing 1 through the feed inlet 12, the servo motor 4 can be driven to work. When the servo motor 4 is working, it will drive the rotating shaft 41 to rotate at the feed inlet 12 and the support block 42. The rotation of the rotating shaft 41 will drive the first bevel gear 51 to rotate. At this time, since the driven shaft 52 and the second bevel gear 53 are in a meshing state, the rotation of the first bevel gear 51 will drive the driven shaft 52 to rotate. Then, through the second bevel gear 53, the driven shaft 52 will rotate in the middle of the hollow bearing sleeve 5. During the rotation of the driven shaft 52, the blade 6 will be driven to rotate synchronously. Under the rotation of the blade 6, the powdery materials flowing into the feed inlet 12 can be crushed.

[0038] This step, through the setting of the crushing component, can implement real-time crushing intervention on the powdery material conveyed to the inside of the silo shell 1, thereby weakening the material agglomeration effect caused by the extrusion stress and air humidity fluctuations during the conveying process, and reducing the formation of difficult-to-drain blocky accumulations of material inside the silo shell 1.
