Title of Invention: A rocker arm mechanism for a waste incinerator and the waste incinerator

[1] The present invention relates to a garbage incinerator, and more particularly to a rocker mechanism for a garbage incinerator.

Background technique

[2] Waste incineration is one of the main ways to achieve waste reduction, harmless and resource treatment. Since the last century, many developed countries have used incineration to treat garbage. After modern incineration, the volume of garbage can be reduced by 80% to 90%. It can eliminate various pathogens, convert harmful substances into harmless substances, and realize resource utilization. Modern waste incineration power plants are equipped with advanced soot purification devices that can greatly reduce atmospheric pollution.

detailed description [33] As shown in Figure 2, the waste incinerator comprises at least one set of successively connected translation grate 1, the inverted grate 2 and the fixed grate 3, the inverted grate shaft 6 that drives the incinerator to reverse, and the support 7; The rocker arm mechanism includes a rocker arm 400 and a drive mechanism 5 rotatably mounted on the bracket 7. The rocker arm 400 includes a fixed connection rocker arm head 401 and a rocker arm body 402. The rocker arm head 401 is fixedly connected with the inverted grate shaft 6. The rocker arm body 402 is provided with a working hole 422 and an inspection hole 412 for maintenance. The distance of the aperture 412 from the axis of the inverted grate shaft 6 is less than the distance of the working aperture 422 from the axis of the inverted grate axis 6.

The drive mechanism 5 includes a housing 501 rotatably mounted on the bracket 7, and a drive rod 502 telescopically mounted in the housing 501; the free end of the drive rod 502 is selectively mounted to the working hole 422 and the access hole 412. on. In this embodiment, the housing 501 is a hydraulic cylinder or a pneumatic cylinder mounted on the bracket 7 by a hinge; the driving rod 502 is a piston rod slidably mounted in the hydraulic cylinder or the pneumatic cylinder; the driving mechanism 5 It also includes a hydraulic or pneumatic source that supplies working fluid or gas to the hydraulic or pneumatic cylinder.

[35] The translation grate 1 includes a bent portion 10, the bent portion 10 is fastened to the side of the inverted grate 2, and the cross section of the inverted grate 2 is curved. The fixed grate 3 is joined to the curved portion 20, and the other side is provided with a bent portion 30 which is engaged with the translational grate 1 of the next set of grate. The turning grate shaft 6 is installed on the lower side of the inverted grate 2, and drives the inverted grate 2 to be turned over.

[36] The garbage incinerator is normally operated, and the drive rod 502 is mounted on the working hole 422. After the driving of the inversion grate 2 is required to be turned, the driving arm 502 of the driving mechanism drives the rocker 400 to rotate, and then the rocker arm 400 drives the rotating grate shaft 6 to rotate, thereby driving the inverting grate 2 to be turned over, and stirring the inverted grate 2 Garbage, for a fuller burning. Thereafter, since the free end of the drive rod 502 is mounted on the working hole 422, even if the driving rod 502 is moved to the maximum stroke position, the curved portion 20 is always engaged with the side of the fixed grate piece 3, thereby avoiding garbage from Sprinkled in the gap.

[37] The waste incinerator is in need of inspection, and the drive rod 502 is mounted on the manhole 412. Therefore, since the inspection hole 412 is located on the side close to the hydraulic cylinder, the angle of the housing mounted on the bracket can be adjusted, so that the driving rod 502 can drive the rocker arm 400 to rotate under the pushing action of the hydraulic cylinder. The angle, thereby pushing the inverted grate 2 to a height by the inverted grate shaft 6 connected to the rocker arm 400, so that the inverted grate 2 completely disengages the fixed grate 3, which is not restricted by the fixed grate 3, and thus remains There is enough space to replace the damaged flip grate 2.

[38] The position of the access hole 412 can satisfy both the stroke of the driving rod 502 and the flipping of the grate under the same stroke. The deflection angle of the sheet 2 is increased to allow sufficient space for disassembly and maintenance of the inverted grate piece 2.

The invention provides a working hole and an access hole on the rocker arm of the garbage incinerator. After the incinerator works normally, the drive rod is mounted on the working hole, which can realize the normal turning of the flipping grate. When the grate piece needs to be repaired, it is convenient to replace the broken grate piece by simply installing the drive rod on the manhole. Moreover, the rocker arm structure is simple and reasonable, and the installation is convenient, and the work efficiency of the damaged furnace row piece replacement can be effectively improved.
