Description

A kind of material-feeding mechanism that fire coal is deposited into bridge-type coal grab coal canopy
[technical field]
The utility model belongs to thermal powerplant or thermal source factory fortune coal measures commander territory, is specifically related to a kind of material-feeding mechanism that fire coal is transported to bridge-type coal grab coal canopy.
[background technology]
At present; The bridge-type coal grab coal canopy fortune coal measures system that thermal powerplant or thermal source factory adopt; Referring to Fig. 1; Generally adopt automobile or overhead belt feeder that fire coal is discharged in the bridge-type coal grab coal canopy, grab coal repeatedly through transporter grab crane again and cooperate other machineries to realize high, the smooth functions such as going up coal that reaches of heap of coal-fired dump.More than two kinds of methods that fire coal is deposited into bridge-type coal grab coal canopy have following problem:
(1) main coal yard machinery all adopts transporter grab crane, and the coal yard machinery of this pattern is made up of cart, dolly, crane span structure, grab bucket, driver's cab and electric part.Generally speaking, receive the spacial influence of transporter grab crane grasping mechanism, it is high that the coal piling height in the indoor coal storage yard can only be piled 6m, and the space availability ratio of indoor coal storage yard is lower, and indoor coal storage yard takes up an area of bigger;
(2) need to realize coal-fired function of rationally stacking, increase power plant's operating cost and cause secondary environmental pollution through rehandling;
When (3) automobile is unloaded coal conceptual design, need take bridge-type coal grab coal canopy certain space and unload, reduce the coal storage space, in addition, also need a cover spray dust remover, increase equipment cost a little to be set unloading;
(4) the overhead belt feeder conceptual design of unloading coal is higher at the side dump of unloading coal, and coal-stopping wall receives load bigger, increases civil engineering cost.
In addition on the one hand; Under the situation of electric coal market in general supplydemand relationship growing tension; Electricity coal price lattice continuous rise accounts for the power plant of cost of electricity-generating 70% for fuel cost, how to reduce the coal consumption of generating mark to greatest extent; And then reduce fuel cost to greatest extent, be the problem of each Power Plant Fuel supvr emphasis thinking.For fuel management, adopting coal mixing combustion is an important effective technological means.Current, generally there is following problem in coal blending in the power plant that adopts bridge-type coal grab coal canopy coal yard:
(1) coal yard comes dump to put at random, and the data statistics, the recording accuracy that cause depositing coal are low;
(2) coal yard comes dump to put to stride dump discharging difficulty bigger, and the cost that causes unloading coal increases;
(3) coal blending is mainly manual operation, mix be made into higher.
[utility model content]
