Abstract

The invention discloses a rotary grate device, which is characterized in that a grate is arranged in a furnace wall, an ash knife is arranged on the furnace wall and located on the lower side of the grate, an ash discharging opening is formed in the bottom of the grate and connected with an ash falling hopper, an ash tray is arranged between the lower portion of the grate and the furnace wall, and the grate drives the ash tray and a grate gear to rotate through a driving motor. The rotary grate device is suitable for the organic solid waste which has the characteristics of large component fluctuation and difficult burnout, and ensures that the organic solid waste has a relatively high burnout rate; and meanwhile, by adjusting the deslagging speed, it is ensured that organic solid waste has enough standing time in the furnace, and the burn-off rate of the organic solid waste on the rotary grate is effectively increased by increasing stirring of the grate.

Description

technical field [0001] The invention belongs to the technical field of fire grate, and in particular relates to a rotary fire grate device. Background technique [0002] With the development of the economy, the use of rotary grate in our country has increased sharply, but the common problem of rotary grate at present is that it cannot overcome the large change in the composition of the materials to be processed, and there is strict screening of the materials entering the grate, so that the rotary grate The scope of use is limited. If the materials entering the grate are not strictly screened, problems such as burning and coking, unsmooth ash discharge, and blockage of ash discharge will occur in the furnace, resulting in local high temperature, which will damage the working environment of the rotary grate, so that the entire furnace system will be damaged. stop, causing a huge economy. Contents of the invention [0003] The technical problem to be solved by the present i...
