Description

Technical Field

[0001] This application relates to the field of material storage equipment, specifically to a temporary storage silo with arch-breaking and conveying functions. Background Technology

[0002] In industrial production, temporary storage warehouses are generally used for temporary storage of materials, serving as an intermediate buffer to balance the efficiency differences between various production stages and ultimately ensure the stable operation of the production process.

[0003] However, in actual production, it has been found that traditional temporary storage silos have a simple structure, generally a cone shape that is wider at the top and narrower at the bottom. Materials easily accumulate and arch at the discharge port, especially when storing wet or sticky materials, or materials with specific particle sizes. As the accumulation height increases and the accumulation time lengthens, the material easily forms a stable arch or dome-shaped structure above the discharge port at the bottom of the silo, obstructing the normal flow of materials. This leads to a sudden interruption of material flow during production discharge, requiring the application of external force (vibration, knocking, etc.) to break the arch structure and restore material flow. Frequent checks for arching by designated personnel may also be necessary. In recent years, some temporary storage silos have been equipped with arch-breaking devices. These devices primarily use air-blowing, mechanical vibration, optimizing the silo wall angle, and mechanical stirring. However, for wet, sticky, and poorly flowing materials, the arch-breaking and conveying effects remain unsatisfactory.

[0004] In view of the above, temporary storage bins have problems such as easy arching and poor conveying for wet, sticky, and poorly flowing materials. Utility Model Content

[0005] The purpose of this application is to provide a temporary storage bin with anti-bridging and conveying functions. Based on the traditional temporary storage bin, the shape of the bin body is improved, an anti-bridging structure is added inside the bin body, the discharge port is enlarged, and a conveying device is installed. The improved temporary storage bin can effectively prevent material bridging, improve material conveying efficiency, enhance the continuity and stability of production, and solve the problems of easy bridging and poor conveying of wet, sticky, and poorly flowing materials in temporary storage bins.

[0006] The temporary storage bin provided in this application, which has the functions of breaking arches and conveying, adopts the following technical solution: it includes a bin body, an arch-breaking mechanism, and a conveying mechanism. The conveying mechanism is fixedly connected to the lower end of the bin body, and the arch-breaking mechanism is provided in the middle of the bin body. The arch-breaking mechanism includes a drive shaft and a driven shaft. The drive shaft is arranged on the left and right side walls of the bin body through bearings on both sides. One end of the driven shaft is arranged on the front and rear side walls of the bin body through bearings, and the other end is rotatably connected to the drive shaft through a connecting device. The axes of the drive shaft and the driven shaft are on the same horizontal plane and the included angle is perpendicular. The drive shaft is fixedly connected to the drive shaft arch-breaking rod through a bushing, and the driven shaft is fixedly connected to the driven shaft arch-breaking rod. The drive shaft drives the drive shaft arch-breaking rod and the driven shaft to rotate, and the driven shaft drives the driven shaft arch-breaking rod to rotate. A blowing device is provided on the lower side wall of the bin body. The blowing device is below the arch-breaking mechanism and is linked with the arch-breaking mechanism.

[0007] Furthermore, the upper part of the silo body is a cuboid structure, and the lower part is a conical structure. The conveying mechanism includes a spiral blade and a conveying motor, and the conveying motor is rotatably connected to the spiral blade.

[0008] Furthermore, the blowing device includes nozzles, which are fixedly connected to the conical sidewall at the lower end of the silo body by threads, and multiple nozzles are evenly spaced.

[0009] Furthermore, two active shaft arch-breaking rods are arranged perpendicularly and symmetrically to the axis on the bushing, and two driven shafts are arranged symmetrically to the axis of the active shaft. Each driven shaft is equipped with one driven shaft arch-breaking rod, and the active shaft arch-breaking rods and driven shaft arch-breaking rods are arranged in groups at intervals.

[0010] Furthermore, the lengths of the drive shaft arch-breaking rod and the driven shaft arch-breaking rod are matched with the clearance of the side wall of the silo.

[0011] Furthermore, the materials of the drive shaft anti-arch rod and the driven shaft anti-arch rod are wear-resistant WC-Co alloy.

[0012] Furthermore, the active shaft arch-breaking rod is a triangular prism-shaped rod with one edge facing the direction of rotational arch breaking, while the driven shaft arch-breaking rod has a trapezoidal structure.

[0013] Furthermore, the connecting device includes a first bevel gear and a second bevel gear. The first bevel gear is sleeved and fixed on the drive shaft, and the second bevel gear is fixedly connected to one end of the driven shaft. The first bevel gear drives the second bevel gear to rotate.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This temporary storage bin features both arch-breaking and conveying functions. It comprises a bin body, an arch-breaking mechanism, and a conveying mechanism. The arch-breaking mechanism has drive and driven shaft arch-breaking rods arranged in groups at intervals. Driven by a suitable motor speed, the drive and driven shafts rotate perpendicularly and alternately to break up arches in both directions. A blowing device, activated in conjunction with the arch-breaking mechanism, can blow off material adhering to the side walls, effectively assisting in arch-breaking in areas inaccessible to the arch-breaking rods. The conveying mechanism, located at the lower end of the bin body, uses a conveying motor to drive spiral blades, continuously and stably conveying the arch-broken material within the storage bin. The drive and driven shaft arch-breaking rods are made of wear-resistant WC-Co alloy, improving the wear resistance of components and avoiding frequent downtime for maintenance.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0023] like Figure 1 and Figure 2As shown, a temporary storage bin with arch-breaking and conveying functions includes a bin body 1, an arch-breaking mechanism 2, and a conveying mechanism 3. The conveying mechanism 3 is fixedly connected to the lower end of the bin body 1 (3500mm long, 2000mm wide, and 3500mm high). The arch-breaking mechanism 2 is located in the middle of the bin body 1. The arch-breaking mechanism 2 includes a drive motor 6, a drive shaft 7 (shaft diameter φ80mm), and a driven shaft 8 (shaft diameter φ60mm). The drive shaft 7 is arranged on the left and right side walls of the bin body 1 through bearings on both sides. One end of the drive shaft 7 is hinged to the drive motor 6, and one end of the driven shaft 8 is connected to the drive motor 6. The bearings are arranged on the front and rear side walls of the silo body 1, and the other end is rotatably connected to the drive shaft 7 through the connecting device 9. The axes of the drive shaft 7 and the driven shaft 8 are on the same horizontal plane and the included angle is perpendicular. The drive shaft 7 is fixedly connected to the drive shaft arch-breaking rod 11 through the bushing 10, and the driven shaft 8 is fixedly connected to the driven shaft arch-breaking rod 12. The drive shaft 7 drives the drive shaft arch-breaking rod 11 and the driven shaft 8 to rotate, and the driven shaft 8 drives the driven shaft arch-breaking rod 12 to rotate. The lower conical side wall of the silo body 1 is provided with a blowing device 15. The blowing device 15 is below the arch-breaking mechanism 2 and is linked with the arch-breaking mechanism 2.

[0024] The drive motor 6 is a servo motor (power 5.5kW, rated torque 120Nm), which can better control the driving force and speed. It is fixed on the bin body 1 to provide driving force for the drive shaft 7. The two ends of the drive shaft 7 are fixed to the bin body 1 of the temporary storage bin through bearings and connected to the drive motor 6. The drive shaft arch-breaking rod 11 is fixed on it through the bushing 10. Under the drive of the drive motor 6, the drive shaft 7 can rotate, thereby driving the drive shaft arch-breaking rod 11 to rotate and break the arches of the material. The drive shaft 7 is provided with a connecting device 9. When the drive shaft 7 rotates, it can transmit power to the driven shaft 8, driving the driven shaft 8 to rotate. The driven shaft arch-breaking rod 12 is fixed on the driven shaft 8 and can rotate together to break the arches of the material. Driven by the appropriate speed of the drive motor 6, the vertically alternating rotation of the drive shaft 7 and the driven shaft 8 drives the drive shaft anti-bridging rod 11 and the driven shaft anti-bridging rod 12 to bidirectionally break up the material, allowing the material to smoothly pass through the lower end into the conveying mechanism 3, and then be conveyed to the discharge port for the next production process. A blowing device 15 is installed on the conical side wall at the lower end of the silo 1. It operates intermittently during the operation of the anti-bridging mechanism 2, with a frequency of 10 times per minute, creating airflow on the conical side wall to break up the material in the dead corners that the anti-bridging mechanism 2 cannot reach.

[0025] The upper part of the silo 1 is a cuboid structure, and the lower part is a conical structure. The conveying mechanism 3 includes a spiral blade 4 and a conveying motor 5, which is rotatably connected to the spiral blade 4. The conveying motor 5 is a variable frequency motor (3kW power, 20-50Hz frequency), and its speed can be adjusted by a PLC and frequency converter according to production conditions. The spiral blade 4 is a continuous spiral with a diameter of 300mm and a pitch of 150mm. The conveying motor 5 provides driving force for the conveying mechanism 3. The conveying mechanism 3 is fixed at the lower end of the silo 1. Driven by the conveying motor 5, it drives the spiral blade 4 to rotate, pushing the material in the silo 1 to the discharge port for the next process. The blowing device 15 includes nozzles 16, which are threadedly fixed to the four side walls of the conical structure at the lower end of the silo. Multiple nozzles 16 are evenly spaced, and an external air source is connected to each nozzle 16 through an air pipe with an air pressure of 0.3MPa. The blowing device 15 is activated in conjunction with the arch-breaking mechanism 2 during operation, supplying air at a frequency of 10 times / minute to blow material off the sidewalls. This effectively assists in breaking up materials adhering to the sidewalls and provides good support for areas that the arch-breaking rod cannot reach. Figure 3 As shown, two active shaft arch-breaking rods 11 are symmetrically and perpendicularly arranged on the bushing 10 relative to the axis of the active shaft 7. Two driven shafts 8 are symmetrically arranged relative to the axis of the active shaft 7, and one driven shaft arch-breaking rod 12 is arranged on each driven shaft 8. The active shaft arch-breaking rods 11 and driven shaft arch-breaking rods 12 are arranged in groups at intervals. Figure 3 As shown, three sets of active shaft arch-breaking rods 11 and driven shaft arch-breaking rods 12, along with a driven shaft 8, are arranged on the axis of the active shaft 7. The lengths of the active shaft arch-breaking rods 11 and 12 are fitted with the clearance of the side wall of the silo 1, maximizing the agitation of the material during rotation and thus increasing arch-breaking efficiency. The active shaft arch-breaking rods 11 and 12 are made of wear-resistant WC-Co alloy, which improves the wear resistance of the components and avoids frequent downtime for maintenance. The active shaft arch-breaking rod 11 is a triangular prism-shaped rod with one edge pointing towards the direction of rotational arch-breaking, while the driven shaft arch-breaking rod 12 has a trapezoidal structure, with a certain gap between them. The hypotenuse of the driven shaft arch-breaking rod 11 is parallel to the constricted hypotenuse at the lower end of the silo 1, preventing collision during rotational arch-breaking and enabling a shearing effect on the material. Figure 4 As shown, the connecting device 9 includes two first bevel gears 13 and two second bevel gears 14. The first bevel gears 13 and the second bevel gears 14 have a module of 8 and 24 teeth, with a transmission ratio of 1:1. The first bevel gears 13 are sleeved and fixed on the drive shaft 7, and the second bevel gears 14 are fixed to one end of the driven shaft 8. The first bevel gears 13 drive the second bevel gears 14 to rotate. Inside the connecting device 9, the first bevel gears 13 are fixed on the drive shaft 7, and the second bevel gears 14 are fixed on the driven shaft 8. The drive shaft 7 and the driven shaft 8 are fixed to the housing of the connecting device 9 by bearings.

[0026] In addition, the drive shaft anti-arch rod 11 and the driven shaft anti-arch rod 12 can also be arranged in other numbers in the direction of the drive shaft 7. The drive shaft anti-arch rod 11 can also be other prismatic rods, and the driven shaft anti-arch rod 12 can also be other shaped structures, such as combinations of multiple rods or multiple triangular structures. The connecting device can also be other structures, such as worm gears or right-angle planetary gear sets, etc.

[0027] During production, materials from the previous process are temporarily stored in the temporary storage bin 1. When materials need to be discharged for the next production process, the drive motor 6 is turned on, driving the drive shaft 7 and the drive shaft anti-bridging rod 11 fixed thereon to rotate. The first bevel gear 13 in the connecting device 9 drives the second bevel gear 14 to rotate, reversing the rotation axis and transmitting power to the driven shaft 8, which drives the driven shaft anti-bridging rod 12 fixed thereon to rotate. The drive shaft anti-bridging rod 11 and the driven shaft anti-bridging rod 12 work together, rotating alternately in the vertical direction to collaboratively break up the arching phenomenon caused by material accumulation. The blowing device 15 starts synchronously when the drive motor 6 starts, achieving linkage, and supplies air at a frequency of 10 times / minute to blow material off the side walls, which can blow off the material adhering to the side walls and play a good auxiliary role in breaking up arches in areas that the anti-bridging rod cannot reach. At the same time, the conveyor motor 5 is turned on, driving the spiral blades 4 to rotate, conveying the material in the bin forward to the discharge port, through which it enters the next production process.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
