Description

Technical Field

[0001] The utility model belongs to the technical field of grate bar structures, in particular to a sintering machine trolley anti-blocking and anti-sticking grate bar structure. Background Art

[0002] After the material completes the sintering process on the sintering machine trolley, the finished sintered ore is turned over at the tail of the sintering machine and sent to the single-tooth roller crusher. After the material is turned over, some finished crushed ore often adheres to the sintering machine grate bars, causing blockage in the gaps between the grate bars of the sintering machine trolley. After the gaps between the grate bars are blocked, the air permeability of the material during the sintering process on the trolley is affected, and the utilization rate of the sintering main exhaust fan is reduced, thereby affecting the sintering quality. The anti-blocking grate bars can reduce the adhesion rate of the material on the sintering machine grate bars, and fundamentally solve the occurrence of the sintering machine grate blockage phenomenon during the sintering process. Utility Model Content

[0003] The purpose of the utility model is to provide a sintering machine trolley anti-blocking and anti-sticking grate structure, which increases the gap between the grate surfaces by arranging grooves, specifically by optimizing the appearance design of the sintering machine grates, thereby increasing the permeability between the grate bars, avoiding the blocking phenomenon caused by fine particles of the bottom material being mixed in the gaps, and reducing the phenomenon of material being mixed in the gaps of the finished sintered ore after unloading. At the same time, the casting process is used to make the grate surface smoother, reducing the probability of material retention on the grate bars, and solving the problem that some finished product crushed ores often stick to the sintering machine grates after the existing material overturns, causing blocking of the gaps between the grate bars of the sintering machine trolley, affecting the air permeability of the material during the sintering process on the trolley after the gaps between the grate bars are blocked, and reducing the utilization rate of the sintering main exhaust fan, thereby affecting the firing quality.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The utility model discloses a sintering machine trolley anti-blocking and anti-sticking grate structure, comprising a grate, two protrusions fixedly connected to the front and back sides of the grate, anti-sticking components are provided on the left and right sides of the bottom of the grate, the two anti-sticking components contain the same parts, grooves are provided on the front and back sides of the top of the grate, and the grooves are provided, specifically by optimizing the appearance design of the sintering machine grate, so as to increase the gap between the grate surfaces, increase the permeability between the grate bars, avoid the sticking and blocking phenomenon caused by fine particles of the bottom material being mixed in the gaps, reduce the phenomenon of material being mixed in the gaps of the finished sintered ore after unloading, and at the same time, utilize the casting process to make the grate surface smoother, and reduce the probability of material remaining in the grate.

[0006] Furthermore, a leakage groove is formed on one side corresponding to the two grate bars through two grooves, the groove width is set to five millimeters, the groove depth is set to eight millimeters, the width of one side corresponding to the two grate bars is sixteen millimeters, the cross-sectional thickness of the grate bars is fifty millimeters, and a groove with a width of five millimeters and a depth of eight millimeters is added to the upper surface of the grate bars, and the spacing of the existing gaps on the surface of the grate bars is increased, so that the original gap on the upper surface of the grate bars is increased from six millimeters to sixteen millimeters, the depth of the grooves on the surface of the grate bars is eight millimeters, the original load-bearing cross-sectional thickness of the grate bars is fifty-eight millimeters, and the cross-sectional thickness of the grate bars after the transformation becomes fifty millimeters.

[0007] Furthermore, the anti-sticking component includes a slide rail, and a plurality of collision protrusions 1 are fixedly connected to the top of the slide rail, and a collision protrusion 2 is fixedly connected to the outer surface of the grate bar. By setting the anti-sticking component, specifically when the grate bar moves, the collision protrusion 2 contacts the collision protrusion 1, and the grate bar can move up and down slightly when moving, thereby generating a certain activity and vibration effect, which can not only dredge the leakage groove through the activity, but also the vibration generated will vibrate the material stuck on the surface of the grate bar down, reducing the occurrence of adhesion and sticking.

[0008] Furthermore, the right side of the slide rail contacts limit plate 1, and the left side of the slide rail contacts limit plate 2. The top of limit plate 1 and the top of limit plate 2 are both fixedly connected to the surface of the grate bar. When the grate bar moves, limit plate 1 and limit plate 2 play a role in limiting and stabilizing the grate bar.

[0009] Furthermore, the front and back sides of the collision bump 1 are both inclined, the front and back sides of the collision bump 2 are both inclined, and the front and back sides of the bottom of the collision bump 2 are both arc-shaped. When the collision bump 2 contacts the collision bump 1, the collision bump 2 will drive the grate bars to be pushed upward, and then after the collision bump 2 leaves the collision bump 1, it will reset downward due to gravity.

[0010] The utility model has the following beneficial effects:

[0011] The utility model increases the gap between the grate bar surfaces by arranging grooves, specifically by optimizing the appearance design of the sintering machine grate bars, thereby increasing the permeability between the grate bars, avoiding the clogging phenomenon caused by fine particles of the base material being mixed in the gaps, and reducing the phenomenon of material being mixed in the gaps of the finished sintered ore after unloading. At the same time, the casting process is used to make the grate bar surface smoother, reducing the probability of material remaining in the grate bars.

[0012] The utility model provides an anti-sticking component, specifically, when the grate bars move, they collide with the second protrusion and then contact with the first collision protrusion, so that the grate bars can move slightly up and down when moving, thereby generating a certain activity and vibration effect, which can not only dredge the leakage groove through the activity, but also generate vibrations to vibrate the materials stuck on the surface of the grate bars, thereby reducing the occurrence of sticking.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5As shown, the utility model is a sintering machine trolley anti-blocking and anti-sticking grate structure, including a grate 1, two protrusions 11 are fixedly connected to the front and back of the grate 1, and anti-sticking components 12 are provided on the left and right sides of the bottom of the grate 1. The two anti-sticking components 12 contain the same parts. Grooves 13 are provided on the front and back of the top of the grate 1. By setting the grooves 13, specifically by optimizing the appearance design of the sintering machine grate 1, the gap between the surfaces of the grate 1 is increased, the permeability of the grate 1 is increased, and the blocking phenomenon caused by fine particles of the bottom material being mixed in the gaps is avoided, and the phenomenon of material being mixed in the gaps after the finished sintered ore is unloaded is reduced. At the same time, the casting process is used to make the surface of the grate 1 smoother, reducing the probability of material remaining in the grate 1.

[0024] The two grate bars 1 have two grooves 13 on one side thereof to form a drain groove 14. The groove 13 is five millimeters wide and eight millimeters deep. The two grate bars 1 have a width of sixteen millimeters on one side thereof and a cross-sectional thickness of fifty millimeters.

[0025] The anti-sticking component 12 includes a slide rail 121, and a plurality of collision protrusions 122 are fixedly connected to the top of the slide rail 121, and a collision protrusion 2 125 is fixedly connected to the outer surface of the grate 1. By setting the anti-sticking component 12, specifically when the grate 1 moves, the collision protrusion 2 125 contacts the collision protrusion 1 122, which can make the grate 1 move up and down slightly when moving, thereby generating a certain activity and vibration effect. Not only can the leakage groove 14 be dredged through the activity, but the vibration generated will also vibrate the material stuck on the surface of the grate 1, thereby reducing the occurrence of adhesion and sticking.

[0026] The right side of the slide rail 121 contacts the limiting plate 1 123 , and the left side of the slide rail 121 contacts the limiting plate 2 124 . The top of the limiting plate 1 123 and the top of the limiting plate 2 124 are both fixedly connected to the surface of the grate bar 1 .

[0027] The front and back sides of the first collision protrusion 122 are both inclined, the front and back sides of the second collision protrusion 125 are both inclined, and the front and back sides of the bottom of the second collision protrusion 125 are both arc-shaped.

[0028] A specific application of this embodiment is:

[0029] A groove 13 with a width of five millimeters and a depth of eight millimeters is added to the upper surface of the grate bar 1, and the gap spacing on the surface of the existing grate bar 1 is increased, so that the original gap on the upper surface of the grate bar 1 is increased from six millimeters to sixteen millimeters. The depth of the groove 13 on the surface of the grate bar 1 is eight millimeters. The original load-bearing section thickness of the grate bar 1 is fifty millimeters. After the transformation, the section thickness of the grate bar 1 becomes fifty millimeters, and the depth of the sixteen-millimeter groove 13 is eight millimeters. The gap between the two grate bars 1 at the leakage groove 14 is changed from six millimeters to sixteen millimeters. The appearance design is carried out on the basis of the original grate bar 1 mold, and a groove 13 with a depth of eight millimeters and a width of five millimeters is opened on the upper surface of the grate bar 1. After the gap between the upper surfaces of the grate bars 1 is increased, the smaller particles of the bottom material will not be mixed in the surface of the leakage groove 14. After the material is unloaded, it can slide down with the entire plate of material on the trolley, and the lowered grate When the grate bar 1 is in motion, the grate bar 1 will slide on the slide rail 121, and the collision protrusion 2 125 on the surface of the grate bar 1 will contact the collision protrusion 1 122. When the collision protrusion 2 125 contacts the collision protrusion 1 122, the collision protrusion 2 125 will drive the grate bar 1 to be pushed upward, and then the collision protrusion 2 125 will leave the collision protrusion 1 122 and reset downward by gravity. This reciprocating motion can make the grate bar 1 move up and down slightly when moving, thereby producing a certain activity and vibration effect, which can not only dredge the leakage groove 14 through the activity, but also generate vibrations that will vibrate the materials stuck on the surface of the grate bar 1, reducing the occurrence of adhesion and sticking. When the grate bar 1 is in motion, the limit plate 1 123 and the limit plate 2 124 play a role in limiting and stabilizing the grate bar 1.
