Description

Technical Field

[0001] The utility model relates to the technical field of ball press machine silos, in particular to a material blocking alarm device for a ball press machine silo. Background Art

[0002] The ball press is mainly used to press powder materials that are difficult to form. It is characterized by high forming pressure, adjustable main engine speed, and a spiral feeding device. Since 2002, relevant institutes in the metallurgical industry have conducted scientific research and adopted high-pressure powder ball presses to press the powder out of the kiln into balls for smelting. Some foreign steel mills and my country's Baosteel and Anshan Iron and Steel have already used it.

[0003] For example, the authorization announcement number "CN220562243U" is named a ball press silo anti-blocking alarm device. Although a notch is opened at the lower end of the baffle plate to prevent the reverse impact of the material hitting the silo wall when the top is fed, thereby avoiding the occurrence of false alarms, the existing ball press silo anti-blocking alarm device uses the angle at which the material moves inside the silo to push the baffle plate to flip to identify whether the height of the material inside the silo is easy to overflow. However, when a large amount of material is poured into the silo, the material will directly fill both sides of the baffle plate. In this way, the flipping side of the baffle plate will encounter resistance and be difficult to flip, so that subsequent material will continue to fill the silo until the baffle plate is buried. In this way, excessive material will use density pressure to squeeze the baffle plate, making it unable to move and unable to flip, and the ball press silo anti-blocking alarm device cannot trigger the alarm function, affecting the use effect of the ball press silo anti-blocking alarm device.

[0004] At the same time, the existing ball press silo anti-blocking alarm device is directly installed and fixed on the outer wall of the silo of the ball press, which results in the device being unable to be frequently disassembled for maintenance and replacement. The material inside the silo will constantly wear the baffle plate and the movable rod over time. Therefore, the silo anti-blocking alarm device that is inconvenient to replace and disassemble will cause excessive failures and losses, thus affecting the service life of the silo anti-blocking alarm device.
