Problems solved by technology

[0003] In order to solve the above problems, the current method is to stop the running slag removal machine, remove a few links on the chain corresponding to the deflected scraper, and adjust them after removal to achieve deviation correction, which is not only time-consuming and laborious, but also affects boiler slag discharge. normal operation of
At the same time, there is no speed and current display on the existing DCS. The speed of the slag machine needs to be manually adjusted by the operator on the spot according to the amount of slag. There are problems of adjustment lag and poor accuracy.

Abstract

The invention provides a slag salvaging machine of a power plant boiler. The slag salvaging machine comprises a slag salvaging body, the slag salvaging body comprises a machine head, a machine tail and a guide pressing wheel, the machine head is arranged on one side of the machine tail, and the guide pressing wheel is arranged on the lower side of the slag salvaging body; an adjusting unit comprises chains and scraping plates, the chains are supported by the guide pressing wheel, and the multiple scraping plates used for scraping materials are evenly connected between the two chains; and a control unit comprises a speed regulation module and a control module, and the speed regulation module and the control module are arranged on one side of the slag salvaging body. The slag salvaging machine has the beneficial effects that the lengths of the chains on the two sides can be changed through hydraulic equipment, automatic deviation rectifying adjustment of the chains and the scraping plates can be achieved, time and labor are saved, the deviation rectifying efficiency is greatly improved, meanwhile, the slag salvaging machine operates stably, and boiler slag discharging smoothness is achieved. Meanwhile, the rotating speed of the slag salvaging machine can be adjusted along with the amount of slag, and the defects that manual speed adjustment lags behind and is low in accuracy are overcome.

Description

technical field [0001] The invention relates to the technical field of power plant slag extractor equipment, in particular to a power plant boiler slag extractor. Background technique [0002] Now large-capacity and high-parameter thermal power has become the mainstream unit of coal-fired units, and the requirements for the operation stability and reliability of the units are getting higher and higher. The slag scraper of the coal-fired unit is the only channel for the slag discharge of the unit. During the operation of the scraper-type slag scraper, the scraper is often deflected due to inconsistent stretching of the chains on both sides, chain wear, and large amount of slag. To a certain extent, it will cause the scraper to get stuck, so that the chain will be broken. This kind of unit load limit or even fire extinguishing caused by the failure of the slag scraper frequently occurs in production, which has a little impact on the stable operation of production. It is very...
