Problems solved by technology

The current waste incineration grate is mainly of the horizontal reverse push type. There is no mechanical crushing and stirring equipment on the fire grate, which often causes the waste to be incompletely burned. The heat recovery efficiency, but also affect the sanitary landfill, pollute the environment

Embodiment Construction

[0012] Depend on figure 1 It can be seen that the oscillating forward-moving mechanical grate of the present invention is composed of a drying grate 1, a combustion grate 2 and a post-combustion grate 3, with a drop between each grate. There is a large drop at the ends of the drying grate 1, the combustion grate 2 and the post-combustion grate 3. The purpose is that when the burning garbage falls from the upper grate to the lower grate, due to the impact of the falling The pieces of rubbish are crushed so that the air is easy to contact with the rubbish, so that the flame can quickly spread throughout the rubbish. The ash hopper 4 is arranged under the drying grate 1, the ash hopper 5 is arranged under the combustion grate 2, and the ash hopper 6 is arranged under the post-combustion grate 3.

[0013] see figure 2 and image 3 , each section of grate is composed of grate pieces interlaced with each other to form a downward-sloping stepped movable furnace arrangement and a ...

Abstract

The invention discloses a rocking type direct pushing mechanical grate, which consists of three sections of grates having falling head with each other, including a drying grate, a combustion grate and a post-combustion grate, wherein each section of the grate is arranged into a downward sloping stepped type movable grate arrangement and a fixed grate arrangement through fire grate segments which are in a mutually-staggered form, and a movable support frame under each movable grate arrangement is fixedly connected with a hydraulic piston; and the combustion grate is provided with a cutting blender consisting of a plurality of sector cutting blades which are evenly arranged on a link mechanism and a driven shaft, and the tail of the combustion grate is provided with a turning type full combustion device consisting of an oil pressure piston, a driving shaft, a driving rod, the driven shaft, and a turning mechanism on the driven shaft. The rocking type direct pushing mechanical grate solves the problem that in the prior art rubbishes cannot be burnt completely, improves the combustion efficiency of the rubbishes in an incinerator, and has the advantages of adaptability to complex components of municipal wastes in China, simple structure, convenient maintenance and few malfunctions.

Description

1. Technical field [0001] The invention relates to a fire grate of a garbage incinerator, in particular to a rocking forward mechanical fire grate. 2. Background technology [0002] The main methods of municipal solid waste disposal are landfill, biological composting and incineration. China's waste incineration has just started. Direct landfill will be banned in principle in Europe in the next 10-15 years. China's environmental industry report pointed out that the general trend of waste disposal development is: more and more attention is paid to recycling on the basis of classified collection, the proportion is gradually increased, the standard of waste landfill will be higher and higher, and the proportion of landfill will gradually decrease. Waste incineration will develop steadily, and the proportion of waste heat incineration for power generation will increase. [0003] In the domestic waste incineration system, the incinerator grate is the most critical equipment. ...
