Multi-stage waste heat recovery device convenient for coal cinder processing

Abstract

The invention discloses a multi-stage waste heat recovery device convenient for coal cinder processing. The multi-stage waste heat recovery device comprises a protective shell, wherein a feeding pipe is fixed above the protective shell, and a placing plate is arranged on the inner wall of a clamping device; a hanging ring is arranged on the inner wall of a clamping block, and a fixing plate is fixed on the inner wall of the protective shell; a fixing frame is fixed under an inclined plate; and a clamping ring is arranged on the outer wall of a threaded rod. According to the multi-stage waste heat recovery device convenient for coal cinder processing, an unloading plate, an air blower, a circulating pipeline and a transmission device are arranged; when a user needs to improve the waste heat recovery efficiency of coal cinder, through the unloading plate, the air blower, the circulating pipeline and the transmission device, the user can conveniently carry out segmented treatment on coal cinder of different sizes, so that the waste heat of the coal cinder of different sizes can be played to the maximum extent, the time spent by the user for recycling the coal cinder of different sizes is shortened, and the working efficiency of the user is improved.

Description

technical field [0001] The invention relates to the technical field of coal slag, in particular to a multi-stage waste heat recovery device for convenient processing of coal slag. Background technique [0002] Coal slag is a kind of industrial solid waste. The waste slag discharged from thermal power plants, industrial and civil boilers and other equipment, also known as slag, is mainly composed of silica, alumina, iron oxide, calcium oxide, magnesium oxide, etc. According to the different components, it can be used to make cement, bricks and refractory materials, etc. Some can be used to prepare alumina or extract rare metals such as gallium and germanium. Cinder is a sintered pozzolanic material, which still has hydraulic gelling properties after grinding. It can be processed with cement clinker, cement or with lime and gypsum to produce cement with little or no clinker, and its strength can reach 225-325. Cinder is used as cement mixing material, and the general dosage is...
