Integrated water-cooled grate

Abstract

The invention discloses an integrated water-cooled grate. Fixed water-cooled grate bodies and movable air-cooled grate bodies are arranged on a machine body. Each movable air-cooled grate body is arranged between every two fixed water-cooled grate bodies, the movable air-cooled grate bodies are positioned above or below the fixed water-cooled grate bodies, the fixed water-cooled grate bodies and the movable air-cooled grate bodies are alternately arranged, a water-cooled grate support frame is arranged below each fixed water-cooled grate body, an air-cooled grate support mechanism is arrangedon the lower part of each movable air-cooled grate body, a hydraulic actuating mechanism is arranged on the side face of each movable air-cooled grate body, and a hydraulic cylinder is arranged at thelower end of each hydraulic actuating mechanism. According to the integrated water-cooled grate, the problem that the connection between a movable water pipe which is connected with a current water-cooled grate and moves along with the current water-cooled grate and a fixed water cannot be well sealed due to the motion / movement of the current water-cooled grate is solved, and the problems of leakage of cooling water and high cost caused by the high breakage and replacement rate of water-cooled grate segments are solved. Due to the adoption of the grate segments of the integrated water-cooledgrate, the replacement rate of the grate segments can be reduced by 2 / 3.

Description

technical field [0001] The invention belongs to incineration equipment, and in particular relates to an integrated water-cooled fire grate. Background technique [0002] Water-cooled grate is often used in the incineration of domestic waste, biomass, industrial waste, etc. The existing air-cooled grate cannot operate normally when the low calorific value of the processing object is higher than 2000Kcal / kg, and the material cannot withstand high calorific value combustion However, air cooling cannot effectively cool down the grate, which leads to the fact that the thermal expansion of the existing grate cannot be effectively controlled and cannot withstand higher temperatures. The local high temperature area causes the object to be melted to pass through the floor drain of the air supply port and with it. After the temperature is reduced, it condenses and blocks the movement of the moving grate. Although the conventional water-cooled grate solves the problem of cooling the gr...

AI Technical Summary

Problems solved by technology

This kind of hydraulic cylinder is completely arranged on the furnace head instead of all the hydraulic cylinders of the reciprocating grate that must be arranged in the high temperature area along with the moving grate, which completely avoids the high temperature area arranged under the moving grate or on the side from being affected by the ash falling of the grate Defects and inconveniences such as difficult to remove pollution and inconvenient maintenance in case of failure

[0007] The only shortcoming of the present invention is that it is required to have larger size casting equipment for the grate piece processing unit equipment, but this processing requirement can be met for general medium or large casting processing units
