Dedicated discharging system for ash storage and slag storage

Abstract

The invention discloses a dedicated discharging system for an ash storage and a slag storage. The dedicated discharging system for the ash storage and the slag storage comprises a supporting table, abulk machine body, a built-in cartridge type filter, a draught fan, a local control cabinet and an ash falling hopper, the built-in cartridge type filter is fixed to the top of the bulk machine body,the bulk machine body comprises a mounting base, a material falling structure, a sealing structure, a limiting structure and a material filling control structure, the material falling structure comprises a fixed inner cylinder, a plurality of movable cylinders, a discharging head, a plurality of outer steel wire ropes, a plurality of steel wire discs and a speed reducing motor, the limiting structure comprises an upper limiting protection structure and a lower limiting protection structure, a built-in cartridge type dust remover comprises an upper shell body, a lower shell body, an ash fallingtube, a clean gas outlet, a filtering structure, a reverse blowing structure and a dusty gas inlet, the clean gas outlet is connected with an air inlet of the draught fan through an induced tube, andan air outlet of the draught fan is connected with an air exhausting tube. Operation of dedicated discharging system for the ash storage and the slag storage is stable and reliable, discharging requirements of ash loading trucks with different height can be met, reliable interlocks are arranged between each part, and the degree of automation is high.

Description

technical field [0001] The invention relates to a device for unloading ash and slag silos, in particular to a special unloading system for ash and slag silos. Background technique [0002] The ash and slag formed after burning coal in thermal power plants can be used as ingredients for the production of cement, hollow bricks, and red bricks. The ash can be sold to obtain considerable economic benefits. [0003] The ash formed by burning coal enters the silo from the top of the silo, and the ash in the ash silo is discharged into the ash loading truck (ship) at a certain speed through the unloading device at the bottom of the silo. The device that realizes this function is a dry ash bulk machine. During the operation of the dry ash bulk machine, it is necessary to ensure that no ash is emitted and no ash is leaked, the discharge head can be lifted and lowered flexibly, and reliable interlocks are set between various components, so that the operation is safe and stable. It i...
