The utility model has the advantages that
1. the utility model is mainly to provide a kind of efficient coal pulverizer slag-draining device, by slag-draining device pipe angle
Modification, is changed to 38 ° of level inclination by 30 ° of former level inclination, and two sect of deslagging is changed to 38 ° of horizontal tilt by horizontally disposed
Arrangement cancels intermediate dreg-storing box part, is reduced to small-sized service chamber i.e. blanking maintenance storehouse, and retains former transport box and sealing dress
It sets, allows pebble coal directly deslagging to transport box, while optimizing slag-draining device control and latching logic, solve coal pulverizer
The problem of stone coal and removing slag is unsmooth, and feed opening pebble coal gathers, improves the blanking flow velocity of coal pulverizer pebble coal, keeps pebble coal suitable
It is agile enter slag-draining device inside, reduce damage to coal pulverizer, improve the economy of coal pulverizer operation.
Slag-draining device pipeline is changed to 38 ° of level inclination by original 30 ° of level inclination by the utility model, the structural modification
It proves that the modification at the inclination angle improves the blanking flow velocity of coal pulverizer pebble coal afterwards and by practical operation, keeps pebble coal suitable
It is agile enter slag-draining device inside.
The utility model overcomes in former horizontally disposed two sect flashboard slot of deslagging and easily gathers pebble coal, leads to valve card
It is puckery, the disadvantage of system deslagging is influenced, two sect of deslagging is changed to 38 ° of horizontal tilt arrangements by horizontally disposed, and by its position
It is changed, pebble coal is fallen off naturally, effectively prevent valve body bite, the blocking of pipeline.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is the left view of attached drawing 1.
Attached drawing 3 is original slag-draining device structural schematic diagram.
Specific embodiment:
