[0002] Iron concentrate refers to the concentrate powder obtained by crushing, grinding and beneficiation of natural ore. The concentrate powder is divided into various types according to different beneficiation methods, such as magnetic separation, flotation, gravity separation and other concentrate powders. Good iron concentrate ball-forming performance is the basis and prerequisite for producing high-quality pelletized ore.

[0003] At present, in the process of producing and processing iron ore concentrate, silos are used to store the iron ore concentrate. However, during the use of the silo, since there is no ventilation in the silo and the iron ore concentrate will continue to absorb moisture in the air during storage, when the water content of the iron ore concentrate is high, the friction between the particles will increase, and the particles are easy to stick to each other, causing the ore in the silo to clump and hang on the wall. During the unloading process, the discharge port of the silo is easily blocked by the ore, thereby affecting the production efficiency of the iron ore concentrate. Therefore, in order to solve the above-mentioned problems, an anti-blocking silo for iron ore concentrate is provided. Utility Model Content

[0026] Specifically, through the setting of the driving part, the dispersion blades 2 can be driven to rotate, so as to break up the agglomerated mineral materials in the silo, and prevent the discharge port of the silo from being blocked by the mineral materials during the feeding process. Moreover, through the cooperation of the elastic part and the extrusion part, the impact rod 4 can be driven to repeatedly impact the outer wall of the silo body 1, so that the silo body 1 vibrates, which can further disperse the agglomerated mineral materials, keep the mineral materials in the silo in a loose state, and further prevent the discharge port of the silo from being blocked by the mineral materials.

[0027] The driving part includes: a motor 21 fixedly connected to the outer wall of the silo body 1; wherein a rotating rod 22 is rotatably connected to the silo body 1, one end of the rotating rod 22 is fixedly connected to the output end of the motor 21, and the dispersion blade 2 is fixedly connected to the rotating rod 22.

[0028] Specifically, by starting the motor 21, the output end of the motor 21 drives the rotating rod 22 to rotate, and drives the dispersing blades 2 to rotate, so as to break up the agglomerated mineral materials in the silo.

[0029] The elastic member includes: a straight rod 31, which is fixedly connected to the outer wall of the silo body 1; wherein, one end of the straight rod 31 away from the silo body 1 is fixedly connected to a limiting block 33, and the connecting plate 3 is slidably connected to the straight rod 31; a spring 32 is sleeved on the straight rod 31, and the two ends of the spring 32 are respectively fixedly connected to the surface of the connecting plate 3 and the outer wall of the silo body 1.

[0030] Specifically, by providing the straight rod 31 , the spring 32 and the limit block 33 , the connecting plate 3 and the striker 4 can be guided and reset so that the striker 4 strikes the outer wall of the silo body 1 .

[0032] Specifically, when the rotating rod 22 rotates, it also drives the pulley 8 to rotate, and drives the driving rod 6 and the cam 7 to rotate. Through the continuous rotation of the cam 7, the impact rod 4 can be driven to repeatedly impact the outer wall of the silo body 1, causing the silo body 1 to vibrate.

[0038] When the rotating rod 22 rotates, the pulley 8 is also driven to rotate, and the driving rod 6 and the cam 7 are driven to rotate. When the top angle of the cam 7 contacts the surface of the connecting plate 3 and squeezes it, the connecting plate 3 is moved to drive the striker 4 away from the outer wall of the silo body 1. At the same time, the spring 32 is stretched. When the top angle of the cam 7 is separated from the surface of the connecting plate 3, the elastic force of the spring 32 causes the connecting plate 3 to quickly reset and drives the striker 4 to hit the outer wall of the silo body 1.
