Cantilever build-up welding wear-resisting screening plant

Technical Field

The utility model relates to a smelt the product screening plant field, especially relate to a wear-resisting screening plant of cantilever build-up welding.

Background

Iron metallurgy trade, among the sintering plant material screening process, the sieve that generally adopts is the two-sided stick sieve of individual layer, and figure 1 shows, adopts the stick of spring steel material, when vibrating along with the sieve, produces secondary high frequency resonance for the material granule sinks with higher speed and the faster sieve that passes through of granule that has contacted the sifter, and the stifled hole of sieve mesh high frequency miniaturation has increased the aperture ratio moreover, has increased screening efficiency by a wide margin. However, this screen plate has the following disadvantages: the service life is short, and the stick is spring steel, though the material uses the material that wear-resisting hardness is higher, but sintering plant's screening, and the material erodees it very seriously, and the life-span is short, cost greatly increased.

The utility model discloses a disclose a build-up welding abrasion-resistant bar sieve device in the chinese utility model patent of patent number 201822218303.7, it has used the built-up welding antifriction plate to cut the grating that the system formed, and the wear-resistant grating of build-up welding, contact material face are because of there being one deck build-up welding wearing layer, and hardness is high, and is shock-resistant, the improvement life-span that can be great. However, this screen plate also has disadvantages: when the screen bars cut by the surfacing wear-resistant plates are impacted and smashed by materials, the wear-resistant layers can crack, and the screen bars cannot bear the impact of the materials and break from the middle; because the screen rod is the build-up welding flat plate, does not have elasticity, can not produce high-frequency resonance like the spring billet in the vibration process, the easy stifled hole has reduced the screening efficiency of screen cloth.
