Problems solved by technology

The traditional pebble coal cleaning system generally adopts a hydraulic cleaning system, which uses a circulating water system to transport and clean pebble coal. This type of system not only requires a high-power power system, but also needs to be equipped with a circulating water treatment device, so equipment costs and energy consumption and operating costs are high, in addition, the equipment is also prone to rust, affecting its service life

Abstract

The invention relates to a matching device of a coal grinding mill in a heat power plant, in particular to a vacuum cleaning system for cleaning and conveying stone coal, wastes of the coal grinding mill. The stone coal vacuum cleaning system of the invention comprises a plurality of stone coal gathering units which are respectively connected with a plurality of coal grinding mills, the discharge hole of each stone coal gathering unit is respectively connected with a main delivery duct by a branch pipeline, and one end of the main delivery duct is connected with an air pump by a stone coal bin. The matching device of the invention has simple structure, convenient use, low equipment cost and running cost and long service life.

Description

technical field [0001] The invention relates to a matching equipment of a coal pulverizer in a thermal power plant, in particular to a vacuum cleaning system for cleaning and conveying pebble coal, the waste material of the coal pulverizer. Background technique [0002] During the operation of the coal mill of a thermal power plant, it is necessary to clean up and discharge the waste pebble coal that cannot be pulverized. The pebble coal cleaning system is a supporting system to complete this cleaning process. The traditional pebble coal cleaning system generally adopts a hydraulic cleaning system, which uses a circulating water system to transport and clean the pebble coal. This type of system not only requires a high-power power system, but also needs to set up a circulating water treatment device, so the equipment cost and equipment energy consumption. In addition, the equipment is also prone to rust, which affects its service life. SUMMARY OF THE INVENTION [0003] Th...
