A Coal Pulverizer Pebble Coal Automatic Slagging Collection System

Abstract

The invention discloses an automatic slag discharge collection system for coal mill stone coal, which includes a coal drop hopper, and an automatic collection structure is arranged on the coal drop hopper; the automatic collection structure mainly includes: a first movable baffle plate, a coal drop hopper tube, the second movable baffle, blowing air duct, cold air blowing structure, collection box and several shower heads with the same structure; the first movable baffle is movably installed at one end of the coal hopper, Installed at one end of the coal drop hopper, the second movable baffle is movably installed at one end of the coal drop pipe, the blowing air duct is installed at one end of the coal drop pipe, and the cold air blowing structure is installed at one end of the blowing air duct. The collection box is installed at the other end of the blowing air duct. The present invention relates to the technical field of pebble coal collection devices. It has simple structure, convenient installation and use, extremely low maintenance cost and simple maintenance, low failure rate, and reduces the possibility of spontaneous combustion of pebble coal. Ensure the safe operation of the milling system.

Description

technical field [0001] The invention relates to the technical field of pebble coal collection devices, in particular to a coal mill pebble coal automatic slag discharge collection system. Background technique [0002] At present, in most thermal power plants, coal is generally used as the raw material for power generation. Before coal enters the boiler for combustion, it must be pulverized by a coal mill, so that the fineness of coal powder entering the boiler can be controlled within a more economical range. In order to achieve the best combustion effect. With the continuous rise of coal prices, in order to reduce production costs, many thermal power plants use low-quality coal for combustion, resulting in an increase in the amount of pebble coal in the coal mill. In the existing pulverizing system, most power plants adopt a buffer box type on-site slag discharge system, and the slag discharge method is on-site discharge and manual removal. Pebble coal generally has a rel...
