Description

Technical Field

[0001] This utility model relates to the technical field of waste incinerator components, and in particular to a reciprocating grate for a waste incinerator. Background Technology

[0002] Waste incinerators require the use of grates during operation. Existing grates are placed horizontally or at an angle, and are tightly fitted together during assembly. However, their wear resistance during reciprocating motion is difficult to guarantee. Furthermore, the tight fit of multiple grates inside the furnace makes it difficult for high temperatures to circulate in different directions, resulting in uneven heat distribution and relatively poor high-temperature resistance. In addition, installation usually requires the use of various fastening accessories, which leads to relatively low installation efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a reciprocating grate for a waste incinerator. During installation, it is quickly assembled by interlocking in different directions. The main body is composed of three sets of inclined structures with different angles, ensuring a larger placement space and higher space utilization during incineration. Its front and rear positions are equipped with staggered auxiliary incineration safety grooves, ensuring smoother heat transfer between different directions after multiple units are assembled. This guarantees more uniform heating during incineration and more reliable high-temperature resistance. The sliding installation structure ensures better stability during reciprocating motion, resulting in higher wear resistance and a longer service life.

[0019] like Figures 1 to 7As shown, a reciprocating grate for a waste incinerator includes a grate main support frame 1. The left side of the grate main support frame 1 is higher than the right side. A U-shaped main body mounting groove 2 with an opening facing downwards is provided on the left side of the front of the grate main support frame 1. An arc-shaped support limiting groove 3 with an opening facing right is provided on the right side of the grate main support frame 1. These grooves can be connected and fitted with a sliding rail-like structure, not only assisting in installation but also serving as a stabilizing structure during overall reciprocating movement, ensuring better safety during reciprocating movement. Sliding combination clearance grooves 4 are provided on the front and rear sides of the grate main support frame 1 between the main body mounting groove 2 and the support limiting groove 3, increasing the space at the lower end and preventing stress concentration that could lead to cracking during use. These grooves also allow for rapid airflow in different directions when used in conjunction with other structures. The sliding combination avoidance groove 4 has a cylindrical integral assembly hole 5 that runs through the front and back, allowing for overall fixation and precise assembly with fastening bolts or connecting shafts during assembly. This structure, together with the main body mounting groove 2 and the support limiting groove 3, achieves a stable overall assembly, ensuring stronger overall load-bearing capacity. The right side of the sliding combination avoidance groove 4 has a safety ventilation groove 6 that runs through the right side of the support limiting groove 3. The top of the grate main support frame 1 is a first placement mating surface 7 inclined to the left. To the right of the first placement mating surface 7 is a second placement mating surface 8 inclined to the lower right, and to the right of the second placement mating surface 8 is a third placement mating surface 9 inclined to the lower right. These together form the placement area during overall use. The front and rear sides of the second placement mating surface 8 and the third placement mating surface 9 are respectively provided with staggered auxiliary combustion safety grooves 10 that run vertically through the entire structure, enabling rapid airflow in different directions and preventing uneven heat distribution. The first placement mating surface 7 has an upward-opening moving auxiliary mating groove 11 on its left front and rear positions, which can be used to more accurately combine with auxiliary components and improve the safety of movement during overall reciprocating mating. During installation, it is quickly assembled by interlocking in different directions. The main body placement position consists of three sets of inclined structures with different tilt angles, ensuring more space for placement and higher space utilization during incineration. Its front and rear positions are equipped with staggered auxiliary incineration safety grooves, ensuring smoother heat transfer between different directions after assembling multiple products. This ensures more uniform heating during incineration and more reliable high-temperature resistance. The sliding installation position structure ensures better stability during reciprocating movement, resulting in higher wear resistance and a longer service life.

[0020] Preferably, the lower end of the grate main support frame 1 is provided with a ventilation auxiliary groove, which is connected to the sliding combination ventilation auxiliary groove 4, so that the space at the lower end is larger and the air circulation efficiency is higher during use.

[0021] Preferably, the projection of the moving auxiliary mating groove 11 in the front-to-back direction is a V-shaped structure, and the lower end of the V-shaped structure is an arc-shaped structural surface, which makes the mating space at this position larger during use and can make a more stable mating with the moving auxiliary component.

[0022] Preferably, the upper and lower sides of the support limiting groove 3 are provided with horizontal locking and stabilizing mating planes, which makes the locking stability at this position better, and the mating stability during overall movement can be further improved, and the mating load-bearing capacity is also stronger.

[0023] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
