Movable incinerator grate turning device

Abstract

A movable incinerator fire grate turning device is arranged at the front end, the middle end and the rear end of a fire grate respectively, the turning device at the front end is arranged in the middle of a drying area, and the turning device at the rear end is arranged at the 1 / 3 position of a burnout area. Comprising a material turning shifting piece, an air cooling hollow shaft, a rotary joint, an adjusting structure, a high-temperature-resistant bearing, a speed reducer, a furnace wall, an air supply and exhaust pipeline, a secondary fan and an air supply cooling structure, the air cooling hollow shaft is fixed to the furnace wall through the adjusting structure and the high-temperature-resistant bearing, and a hollow shaft of the speed reducer is connected with one end of the air cooling hollow shaft; a plurality of material turning shifting pieces are evenly arranged on the shaft section, located between the furnace walls, of the air cooling hollow shaft, the secondary fan is connected with the end, close to the speed reducer, of the air cooling hollow shaft through an air supply and exhaust pipeline and a rotary connector, and nozzles are formed in the positions, located on the material turning shifting pieces, of the air cooling hollow shaft. According to the device, an original combustion mode is reserved, stable incineration of low-calorific-value large-particle-size garbage is achieved through the enhanced turbulent flow technology, and the compact and mobile requirements of the device are met.

Description

technical field [0001] The invention belongs to the technical field of fire grate equipment, and in particular relates to a mobile incinerator fire grate turning device. Background technique [0002] Chain grate is a mechanized combustion equipment with a long history, reliable structure and stable operation, and has been widely used. Due to its compact structure, the auxiliary equipment is simple. It is often used in mobile garbage and medical waste incinerators with a processing capacity of >150kg / h. [0003] The combustion method of the traditional chain grate is the combustion of the moving fire bed. From the front end of the grate, a drying zone, a precipitation and volatilization zone, an oxidation zone, a reduction zone, and a burnout zone are successively formed. Since the material is still burning on the incinerator grate, when the calorific value is low and it is not easy to ignite, the remaining material at the bottom is not easy to burn through, which does n...

AI Technical Summary

Problems solved by technology

[0005] According to the application, although the existing chain grate is stable in operation and incineration is good, it has the following disadvantages: the traditional grate restricts the incineration objects, and it is difficult to meet the standard when the material particle size is large and the calorific value is low, and due to the requirements of the mobile structure , the volume is limited within the range of 6m standard container, it is not easy to adopt other reciprocating grate structures
