Description

A kind of pebble coal equal pressure discharge device
Technical field
The utility model is the corollary equipment of power plant coal pulverizer, and especially a kind of stone coal that coal pulverizer is discharged is collected the device of cleaning.
Background technology
The stone coal is a kind of impurity that is mingled in the coal, it must be removed before fire coal enters boiler combustion, therefore simultaneously the stone coal is separated when coal pulverizer moves.
At present, coal-fired power plant's stone coal that coal pulverizer is separated is handled and is divided into usually: three kinds of waterpower, machinery and artificial conveyance.
1, artificial conveyance
Artificial conveyance mainly comprises stone coal collecting bucket, open type activity stone coal bunker, dump truck three parts.Stone coal collecting bucket part, consistent basically under waterpower, three kinds of modes of machinery and artificial conveyance, all be by feeding gate, collection bucket, discharge door is formed, and feeding gate and discharge door are generally selected pneumatic door, and the stone collection bucket generally is furnished with level-sensing device.All need consider worst hot case when turnover bin gate and level-sensing device type selecting.The characteristics of artificial conveyance are exactly manually the stone coal in the stone collection bucket (or being discharged into stone coal on the ground) to be transported to dump truck, are transported to the ash field.Or manually the stone coal is transported to other transfer place, just movable stone coal bunker.Mainly there are two problems in the artificial conveyance system, and the one, site environment pollutes, and the guarantee of operating worker occupational health is poor, and the 2nd, labour intensity is big.
2, waterpower mode of movement
The stone coal collecting part that waterpower is carried stone coal measures system is with to artificially collect design basic identical, also be that feeding gate adds collection bucket and adds discharge door, level-sensing device is installed on the collection bucket, but all designed grid in the collection bucket, meeting has been caused the bulk stone coal of waterpower conveyance conduit plugging is isolated in the stone coal collecting bucket.The stone coal collecting bucket of Hydraulic Transportation System generally need adopt hydrolock stone coal bunker.
The characteristics of Hydraulic Transportation System are that stone collection bucket discharging adopted the Hydraulic Transportation System conveying stone coal of mainly being made up of hydraulic ejector behind the door.The Hydraulic Transportation System water consumption is big, efficient low (20%-40%), and pipeline is easy to wear, and energy consumption is big, and debugging is long running-in period, and the operation maintenance amount is big, and initial investment is bigger, also is unfavorable for the comprehensive utilization of slag.The problem that the stone coal collecting bucket is easily stifled, the leakage around the stone coal collecting bucket emit problem also to can not get solving.
3, mechanical mode of movement
The stone coal collecting bucket and the dump truck of mechanical conveying stone coal measures system are partly identical with artificial conveyance stone coal measures system to the ash field, and mechanical transport portion mainly is made up of one-level conveying equipment and two-stage conveying equipment.
In fact the core of machinery mode of movement design is exactly the definite of the selecting for use of one-level conveying equipment and two-stage conveying equipment, system layout and the method for operation.
The machinery mode of movement, the subterranean tunnel the boiler room in is absolutely necessary, and always has one or two conveyers need be arranged in the underground confined space, and maintenance workload is big, and it is big to overhaul difficulty.Subterranean tunnel domestic demand design dedusting, flushing, drainage, initial investment is big.In addition, most of system also need arrange the climbing conveyer, takies behind the stove or the position, furnace side, makes troubles to entire arrangement and operation behind the stove.
The utility model content
The technical problem that the utility model solves provides a kind of pebble coal equal pressure discharge device, can alleviate labor strength, reduces environmental pollution, the water power energy consumption of saving auxiliary equipment that power plant's factory building is caused, safeguard that coal pulverizer normally moves.
In order to realize technical purpose of the present utility model, the utility model is finished by following technical scheme:
A kind of pebble coal equal pressure discharge device, comprise connector (1), shut-off valve (2), passage (3), seal box (4), seal (5) and move bucket (6), the outlet fixed seal connection of connector (1) and coal pulverizer discharging stone coal, connector (1), shut-off valve (2), passage (3), seal box (4) and seal (5) are fixedly connected sequentially, and seal (5) and mobile bucket (6) are tightly connected by sealing device.
Sealing device between the flange on seal described in the utility model (5) and the mobile bucket (6) is a biserial craspedodrome cylinder (8);
Seal described in the utility model (5) adopts two section hermetically-sealed constructions that collude;
Seal of the present utility model (5) material is selected high temperature estersil rubber for use;
The utility model comprises a standby shut-off valve (9) at least, is installed in the lower end position of passage (3);
The utility model also comprises the bearing capacity inductor (7) that is installed in mobile bucket (6) bottom, and it passes through four unification Wiring modules, and Realtime Level is accurately shown at the scene, can also pass through the material level the signal is far passed to the boiler operatiopn Master Control Room.In order to remind the site operation personnel to be convenient to find the trunkful unit, also specially installed one group of sound and light alarm lamp additional at the electrical control cubicles top, guarantee normally operation.
Has 1 surveillance mirror (10) on the seal box described in the utility model (4) at least;
The utility model comprises a standby mobile bucket at least;
Has a surveillance mirror (11) on the mobile bucket described in the utility model (6) at least.
The beneficial effects of the utility model:
1, all parts of the present utility model; comprise that connector, shut-off valve, passage, seal box, seal, mobile bucket all are tightly connected; guarantee that the stone coal is a sealing state in discharge process; the protection environment; the powder ash does not leak; do not cause the pollution of power plant's factory building, can also change present stone coal processing mode, alleviate the intensity of hand labor.
2, the hot blast blast in the coal pulverizer, be to guarantee that coal pulverizer blows to penetrate the coal dust important measures, in the process of discharging stone coal, need to keep hot-blast pressure, do not have and reveal, pebble coal equal pressure discharge device of the present utility model and coal pulverizer fixed seal connection, the pressure in the coal pulverizer equate with the pressure of pebble coal equal pressure device of the present utility model, can satisfy the maintenance hot-blast pressure and not have the leakage requirement.
