Described filtering grid parts are made up of rotating frame, two rotating shafts, deep bead and Duo Gen rasterization pipelines; This body structure of filtering grid parts is symmetric arrangement, rasterization pipeline is evenly arranged in the rotating frame, two rotating shaft coaxles are arranged symmetrically in lower end, rotating frame both sides and vertical with rasterization pipeline, two rotating shafts can drive rotating frame and rotate, the upper end and the deep bead of rotating frame are rotationally connected, and deep bead is sagging naturally in thin ash bucket with own wt.
The downside of described cinder bucket is provided with the monitoring camera mouth.
The beneficial effect that the utlity model has is:
1, isolates of the wearing and tearing of thin lime-ash, improve the operating efficiency of slag crusher, under equal conditions, prolonged the service life of slag crusher slag crusher.
2, deep bead can cut off backflow flying dust and the dust that is produced by the boiler negative pressure effectively, makes it fall into the thin ash bucket of coal-burning boiler high-temperature ash sorting unit.
3, when emergency appears in slag crusher, can be directly filtering grid be forwarded to cinder bucket side and allow mixed ash directly enter thin ash bucket to enter the next stage conveying equipment again.Lime-ash does not have and effluxes environmental protection, health.
4, the utility model compact conformation is easy to loading and unloading, and is easy to maintenance.
The utility model is used for the sorting of heat power plant boiler high-temperature ash, but in also extensive uses of industry such as metallurgy, electric power, chemical industry.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In Fig. 1, Fig. 2, the utility model comprises air-cooled dried deslagging conveyer 6 and slag crusher 4, and coal-burning boiler high-temperature ash sorting unit 3 is installed between air-cooled dried deslagging conveyer 6 and slag crusher 4; Filtering grid parts 8 are installed at the ash bucket middle part of described coal-burning boiler high-temperature ash sorting unit 3, filtering grid parts 8 are divided into cinder bucket 7 and thin ash bucket 12 with ash bucket, filtering grid 8 sides that are positioned at thin ash bucket 12 1 sides are equipped with spacer pin 11, cinder bucket 7 outlets of head casing 1 one sides of close air-cooled dried deslagging conveyer 6 are connected with slag crusher 4, and opposite side is thin ash bucket.
In Fig. 5, filtering grid parts 8 are made up of rotating frame 14, two rotating shafts 16, deep bead 17 and Duo Gen rasterization pipelines 15; 8 body structures of filtering grid parts are symmetric arrangement, rasterization pipeline 15 is evenly arranged in the rotating frame 14, two rotating shaft 16 coaxial rotating frame lower ends, 14 both sides and vertical that are arranged symmetrically in rasterization pipeline 15, two rotating shafts 16 can drive rotating frame 14 and rotate, the upper end of rotating frame 14 and deep bead 17 are rotationally connected, and deep bead is sagging naturally in thin ash bucket 12 with own wt.
In Fig. 1, the thickness mixed ash of the high temperature red heat that boiler combustion produces drops on the conveyer belt 5 with enclosed air-cooled dried deslagging conveyer 6, the thickness mixed ash on the conveyer belt 5 is transported to the head casing 1 of air-cooled dried deslagging conveyer 6 by drive unit 2, filtering grid parts 8 sortings through coal-burning boiler high-temperature ash sorting unit 3, thick slag enters cinder bucket 7, and thin slag enters thin ash bucket 12 by filtering grid pipe 15.Lime-ash in cinder bucket 7 becomes thin lime-ash through after the fragmentation of slag crusher 4, and then enters in the next stage conveying equipment.And the lime-ash in the thin ash bucket 12 does not need in small, broken bits again and enter in the next stage conveying equipment along the inwall of thin ash bucket yet.
In Fig. 1-4, the two sides of the lower end of cinder bucket 7 are provided with monitoring camera mouth 10.Be furnished with access door 9 on the side of coal-burning boiler high-temperature ash sorting unit 3.Level-sensing device installing port 13 is arranged in the middle and lower part of cinder bucket 7, above monitoring slag crusher 4, monitoring camera mouth 10 have big clinker to pile up, and when the sensor that is installed in level-sensing device installing port 13 has slag crusher 4 fault-signals to send, air-cooled dried deslagging conveyer 6 systems stop to Surveillance center's newspaper, and the Awaiting Overhaul personnel open access door 9 to the equipment working site and handle.When slag crusher 4 faults can't be got rid of at short notice, can forward cinder bucket 7 one sides to crossing filter grid pipe 15, this moment, deep bead was sealed filter grid pipe 15 automatically because of conducting oneself with dignity, and made the thickness lime-ash all directly enter into thin ash bucket 12, and air-cooled dried deslagging conveyer 6 systems can continue normal operation.After slag crusher 4 faults are got rid of, again filtering grid pipe 15 is forwarded to thin ash bucket one side, return to air-cooled dried deslagging conveyer 6 system's positive status.
In Fig. 1 and Fig. 5, deep bead 17 can effectively be tackled a large amount of backflow flying dusts and the dust that is produced by the boiler negative pressure, its speed is reduced and falls to putting in the thin ash bucket 12 along deep bead.
