Problems solved by technology

When the blade turns over and passes through the gap of the fixed grate next time, it often happens that the thermal expansion of the blade is too wide and "stuck" in the above gap, so that the incinerator, which has been continuously incinerated all the year round, has to be shut down frequently for maintenance, thus causing great harm to the incinerator manufacturer. have a huge impact on the actual production benefits of

Embodiment Construction

[0036] For ease of understanding, combine here Figure 1-4 Explain in detail the component structure of the present invention and its specific work flow:

[0037] For the specific structure of the present invention, refer to figure 1 As shown, it includes a main combustion chamber 10 and a fixed grate 10 located in the main combustion chamber 10, and a hot air chamber 30 connected to an external air supply component is arranged below the main combustion chamber 10. The row surface of the fixed furnace 20 is inclined up and down from the feeding end to the slag discharge end to form a slope, and a horizontal stage 22 is provided on the slope surface of the row body in sections. A number of horizontal vents 21 connecting the hot air chamber 30 and the main combustion chamber 10 are added at the straight plate of the horizontal stage 22. All the hot air in the hot air chamber 30 enters the main combustion chamber 10 from the vent 21 to promote the combustion of materials. In order t...

Abstract

The invention belongs to the field of waste incineration equipment and particularly relates to a fixed grate incinerator comprising a main combustion chamber and a fixed fire grate. The fixed fire grate is arranged obliquely, the higher end is provide with a material input end, the lower end is provided a slag outlet for slags after material combustion, and the slag outlet is communicated with a slag discharging component; a hot air chamber is arranged below the main combustion chamber; a hot air supply path penetrates the fixed fire grate; the fixed grate incinerator further comprises an ejecting rod and a power portion; the maximum lift of the ejecting rod penetrates the material layer of the fixed fire grate; an ejecting rod component further comprises a shaft sleeve with the preset length, one end of the shaft sleeve penetrates and is fixedly connected to the fixed fire grate along the moving direction of the ejecting rod, a vent gap allowing the air to penetrate is formed between the shaft sleeve and the ejecting rod, and the other end of the shaft sleeve is communicated with the outside and / or an air cooling chamber. The fixed grate incinerator has the advantages that material burning efficiency is high, the component operation reliability is high, and the service life is prolonged effectively.

Description

Technical field [0001] The invention belongs to the field of garbage incineration equipment, and specifically relates to a fixed grate incinerator with excellent air circulation capability, high service life and low maintenance frequency. Background technique [0002] With the rapid development of production and the rapid rise of the economy, my country has entered the ranks of high-producing cities for municipal solid waste. According to statistics, the total output of urban waste in China in 1990 was 69 million tons, of which Shanghai’s total waste output was 2.7 million tons (approximately 7,500 tons per day), ranking first in the country. As of 2014, the national waste storage over the years has reached more than 6 billion tons, occupying an area of ​​500 million m2 of land. 2 (750,000 mu). Among the more than 600 cities in the country, more than 200 are surrounded by garbage mountains. 1260km from downtown Shanghai 2 50m in range 2 There are nearly 2,000 garbage dumps abov...
