Scale bucket dry slag conveying system

Abstract

A scale bucket type dry slag conveying system comprises a machine case, a motor driving device, a driving chain wheel, a driven chain wheel, a dragging shaft, dragging chain wheels, a hydraulic tensioning shaft, a synchronous sweeper, a mechanical backstop, tensioning chain wheels, dragging chains, scale bucket type conveying belts, a cantilever shaft pressing roller, a simply supported shaft carrier roller, a simply supported shaft pressing roller, a cantilever shaft carrier roller, slag inlet pipes, impact preventing plates, an infrared temperature measuring device, an atomization device, an automatic head adjusting damper, a head air channel, a slag outlet pipe, a tail damper, a tail cooling air pipe and a deflection preventing roller. The synchronous sweeper and the mechanical backstop are mounted on the hydraulic tensioning shaft. The cantilever shaft pressing roller, the simply supported shaft carrier roller, the simply supported shaft pressing roller and the cantilever shaft carrier roller are sequentially mounted on the machine case from top to bottom. According to the scale bucket type dry slag conveying system, no sweeping chain needs to be additionally arranged, and the scale bucket type dry slag conveying system is simple in structure is simple, reliable in operation, high in impact resisting capacity, large in dip angle, long in service life and good in cooling effect. The scale bucket type dry slag conveying system can be widely applied to a conveying and cooling comprehensive treatment system of coal-fired boiler bottom slag, and is especially applied to a dry slag discharging system large in output capacity, large in dip angle, long in distance and efficient in cooling.

Description

Technical field [0001] The invention relates to a scale bucket type dry slag conveying system, which can be widely used in the conveying and cooling integrated treatment system of coal-fired boiler bottom slag, and is especially applied to dry slag discharge with large output, large inclination, long distance and efficient cooling. System. Background technique [0002] Existing coal-fired boiler bottom slag conveying equipment, the cleaning chain is arranged separately, there are problems of slippage, deviation, and low cleaning efficiency. The angle of the head of the equipment is limited. When large units above 660MW are used, secondary conveying equipment needs to be added. This reduces investment costs and floor space, and increases system failure points and maintenance costs. The ash is cooled by manually adjusting the air inlet on the side of the shell and the head automatically adjusts the air inlet type. The head automatically adjusts the air inlet on the top of the equi...

Problems solved by technology

[0002] The existing coal-fired boiler bottom slag conveying equipment, the cleaning chain is arranged separately, there are problems of slipping, deviation, and low cleaning efficiency, and the tilt angle of the equipment is limited. When using a large unit above 660MW, it is necessary to add a secondary conveying equipment. Reduced investment cost and floor area, and increased system failure points and maintenance costs

The cooling of the ash adopts the manual adjustment air inlet on the side of the shell and the automatic adjustment air inlet of the head. The automatic adjustment air inlet of the head is located at the top of the equipment shell, and the adjustment amount is small, and only the surface of the ash is cooled, and it cannot be cooled and accumulated. Inside the slag layer, the cooling efficiency is low
