Description

TECHNICAL FIELD

[0001] The utility model relates to lime production technical field, concretely relates to a grate bar structure of lime kiln boulder breaker. BACKGROUND

[0002] Lime kiln boulder is one of common problems in lime production process. Boulder generally occurs in high temperature area inside lime kiln. Due to the reaction of impurities (such as iron, aluminum, silicon and other components) in raw materials with lime or improper temperature control, hard block or bony material is formed on kiln wall or inside kiln, which seriously affects normal operation and production efficiency of lime kiln. Whenever lime kiln is bouldered in large area, kiln has to be stopped for boulder removal.

[0003] At present, the removed lime boulder is generally broken by boulder breaker. The boulder breaker is arranged at lime kiln discharge port. The lime boulder is discharged to the boulder breaker by scraper. The grate bar is arranged in the boulder breaker. The material is screened by naturally sliding over the upper end face of the grate bar. Small lime is screened by the grate bar to subsequent process. Large lime boulder slides along the grate bar to the dynamic knife and the fixed knife for breaking. However, the connection between the strip-shaped straight rod and the horizontal rod is often broken due to small welding surface during actual use, which causes the broken strip-shaped straight rod to flow into subsequent process and affects normal operation of subsequent equipment.

[0025] The anti-falling rope 7 is further connected between the horizontal fixing piece 2 and the strip pole 1. Even if the connecting portion of the strip pole 1 and the horizontal fixing piece 2 is broken, the strip pole 1 can still be hung through the anti-falling rope 7, and will not fall into the subsequent link.

[0026] Preferably, the horizontal fixing piece 2 is provided with a connecting ring 8 corresponding to each strip pole 1, the connecting portion 3 is provided with a through hole, and the anti-falling rope 7 passes through the connecting ring 8 and the through hole in sequence and is connected at the head and tail. Further preferably, the anti-falling rope 7 is a steel wire rope.

The protrusion is used to disturb the small pieces of lime that slide along the upper end surface of the strip 1, so that small pieces of lime that do not need to be crushed also flow into the fixed knife and the moving knife. The protrusion is located on the middle part 4.

[0028] Preferably, the protrusion is a triangular prism protrusion 9 arranged horizontally along the length direction of the strip 1, and the two ends of the triangular prism protrusion 9 are provided with a guide transition surface 10 matched with the upper end surface of the strip 1. The triangular prism protrusion 9 is trapezoidal in side view.

[0029] The width of the upper end surface of the grate strip remains the same on the connecting part 3 and the middle part 4, and the thickness of the grate strip gradually increases from the middle part 4 to the connecting part 3.

[0030] The existing grate strip is generally connected by a transverse fixing piece at one end, and is fixed in the box body of the lime kiln boulder crusher through the transverse fixing piece, but some grate strips are designed to be supported by the moving knife shaft at the other end in order to improve the carrying capacity, and the rotation of the moving knife shaft is not affected. For example, Chinese patent: A lime kiln boulder crusher for underground circulating soda production, patent number CN202222266829.9.

[0031] A further scheme to improve the carrying capacity of the grate strip is that the middle part 4 is provided with a resting part 5 away from the connecting part 3, and the resting part 5 is provided with an arc surface 6 matched with the moving knife shaft of the boulder crusher.

During screening, the lime boulder material naturally slides over the upper end surface of the strip 1 for screening treatment. The protrusion is used to disturb the small pieces of lime that slide along the upper end surface of the strip 1, so that small pieces of lime that do not need to be crushed also flow into the fixed knife and the moving knife. Small pieces of lime are screened to the subsequent process through the strip 1, and large pieces of lime boulder are crushed between the moving knife and the fixed knife.
