Description

Technical Field

[0001] The invention relates to a material storage bin, in particular to a material storage bin capable of convenient unloading, and belongs to the technical field of thermal power plant application. Background Art

[0002] A thermal power plant is the abbreviation of a thermal power plant. It is a factory that uses combustible materials (such as coal) as fuel to produce electricity. The basic production process of a thermal power plant is: when the fuel burns, it heats water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. The steam turbine then drives the generator to rotate, converting the mechanical energy into electrical energy. Thermal power plants are mainly divided into steam-powered power plants, gas turbine power plants and internal combustion engine power plants.

[0003] The fuel of a thermal power plant is pulverized coal. Thermal power plants use storage silos specifically for temporary storage of pulverized coal, but this will cause problems such as large occupied area. When the storage volume is large, in order not to affect the normal operation of the thermal power plant, it is necessary to design the storage silos around the thermal power plant and equip them with delivery vehicles to transport the pulverized coal to the thermal power plant.

[0004] In the patent document “CN201721638570.9 A Pulverized Coal Storage System”, it enables multiple pulverized coal bins to have different functions at the same time, and the functions are alternately switched over time, thereby improving the safety of pulverized coal storage and transportation and production continuity. The pulverized coal in existing thermal power plants is temporarily stored in storage bins, and an opening is set below the storage bin for pulverized coal unloading. However, it is limited to the placement scenario, and it may be necessary to excavate a foundation pit and then use the storage bin to store the pulverized coal. This will cause inconvenience in unloading, and the pulverized coal in the storage bin will become static and require manual excavation for unloading operations. It is also difficult to control the unloading speed and the pressure during unloading, which brings inconvenience to the operation and easily causes safety problems. The storage and unloading processes are prone to cause the diffusion of pulverized coal ash, which increases the challenge to environmental governance and causes the waste of pulverized coal ash. Currently, there is no storage bin that is reasonable and reliable in structure and can easily unload and prevent the diffusion of pulverized coal ash. Summary of the Invention

The cooperation of the gear 35 and the tooth groove 37 drives the second baffle 36 to slide on the top surface of the silo 1, so that the second baffle 36 opens the square hole. At this time, the second baffle 36 pulls the first baffle 32 to rotate through the connecting rope 38, so that the coal dust in the collecting box 27 falls from the square hole and re-enters the interior of the silo 1, which can avoid the diffusion of coal dust and has a collection function.

[0051] During unloading, the spiral roller 5 is driven by the first motor 4 to rotate in the lifting pipe 3, and the coal powder in the silo 1 enters the lifting pipe 3 from the feeding port 6 and is lifted by the spiral roller 5, so that the coal powder is discharged through the discharge pipe 39. When the spiral roller 5 rotates, it drives the connecting shaft 8 to rotate synchronously, so that the connecting shaft 8 drives the first bevel gear 9 to rotate synchronously. At this time, the transmission of the first bevel gear 9 and the second bevel gear 10 drives the rotating plate 11 to rotate, and the balance of the coal powder at the bottom of the silo 1 is destroyed by the rotating plate 11, so that the coal powder enters the feeding port 6 smoothly, and the rotating plate 11 is set to an elliptical shape, which can reduce the resistance of the rotating plate 11 during rotation and ensure the stable transmission of the rotating plate 11. During unloading, the connecting block 41 and the sleeve 40 are driven to move by the extension of the cylinder 42, so that the sleeve 40 rises and falls at the discharge pipe 39. The height of the discharge is adjusted by the sleeve 40, and it can gradually move upward during unloading to avoid the problem of coal powder ash diffusion caused by excessive drop.

[0052] The above are merely specific embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
