Abstract
The utility model relates to a secondary dust removing device for the ash remover and consists of a ring shaped dust removing mask (2) and a subpressure pipe (3); the upper end of the ring shaped dust removing mask (2)is connected with the bottom of the ash scoop (1) and the ash removing mouth of the ash scoop (1) is sleeved in the ring shaped dust removing mask (2); one end of the subpressure pipe (3) is connected on the mask wall of the ring shaped dust removing mask and is communicated with the ring shaped dust removing mask while the other end is communicated with the dust remover on the dust removing system. The dust car stops under the dust removing mouth first when the dust remover removes dust. The collected dust will be removed on the dust car when the valve of the ash removing mouth is open; the mass raising dust will be removed secondarily by the subpressure pipe which can inhale the dust into the dust removing system as the subpressure pipe is connected with the dust removing mask and the subpressure produced around the ash removing mouth, so the dust will not pollute the environment again.
Description
Technical field
The utility model relates to dust unloadnig apparatus, the dust arrester that particularly uses on dust unloadnig apparatus.
Background technology
Present dust pelletizing system as the steel-making dust pelletizing system, generally comprises deduster and dust unloadnig apparatus, and the dust that deduster is collected is generally packed into by dust unloadnig apparatus and transported in the grey car.Existing dust unloadnig apparatus comprises ash bucket, and the dust that dedusting is collected is collected in earlier in the ash bucket, and when unloading ash, grey car is parked in the below of ash bucket cinder-discharging port earlier, opens the valve on the ash bucket cinder-discharging port, and the dust of collection can unload and install on the grey car.Because the structure of existing dust unloadnig apparatus is not considered the problem of dedusting, in unloading grey process, the cinder-discharging port place can produce a large amount of airborne dusts, causes environment to pollute once more.
Summary of the invention
Technical problem to be solved in the utility model is: for overcoming above-mentioned deficiency, provide a kind of dust unloadnig apparatus final dusting device, the airborne dust that this device produces in the time of unloading ash to dust unloadnig apparatus is collected, and eliminates the once more pollution of dust unloadnig apparatus to environment.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Dust unloadnig apparatus final dusting device, it comprises annular dust excluding hood, negative pressure pipe; The upper end of annular dust excluding hood is connected with the bottom of ash bucket, and the cinder-discharging port of ash bucket is enclosed within the annular dust excluding hood; One end of negative pressure pipe be connected on the cover wall of annular dust excluding hood and with annular dust excluding hood in UNICOM, the deduster UNICOM of the other end and dust pelletizing system.
In the such scheme, be provided with netted dust excluding hood in the annular dust excluding hood, netted dust excluding hood is arranged between the cinder-discharging port and negative pressure pipe air inlet of ash bucket, and the lower end of netted dust excluding hood is connected with the lower end of annular dust excluding hood.
In the such scheme, the mesh diameter of netted dust excluding hood is 3-10mm.
In the such scheme, be provided with valve in the negative pressure pipe.
The operation principle of the utility model dust unloadnig apparatus final dusting device is:
When dust unloadnig apparatus unloaded ash, grey car was parked in the below of ash bucket cinder-discharging port earlier.Open the valve on the ash bucket cinder-discharging port, the dust of collecting unloads and installs on the grey car, because negative pressure pipe and annular dust excluding hood UNICOM, can produce certain negative pressure around the cinder-discharging port, the cinder-discharging port place can produce a large amount of airborne dusts and carry out final dusting by the deduster that the negative pressure pipe sucks dust pelletizing system, therefore, can not cause pollution once more to environment.
Being also advantageous in that of the utility model dust unloadnig apparatus final dusting device:
1, be provided with netted dust excluding hood in the annular dust excluding hood, most of airborne dust that the cinder-discharging port place produces can be attached to netted dust excluding hood under the effect of negative pressure, gathers certain the time, can automatically or rely on artificial vibrations to fall in the grey car of below.
2, be provided with valve in the negative pressure pipe, when not unloading ash, valve closing can be saved power consumption, maintain easily.
Description of drawings
Fig. 1 is a dust unloadnig apparatus airborne dust gathering-device structural representation
Among the figure: 1 ash bucket, 2 annular dust excluding hoods, 3 negative pressure pipes, 4 valves, 5 netted dust excluding hoods, 6 deduster air inlet pipe.
The specific embodiment
The utility model dust unloadnig apparatus final dusting device as shown in Figure 1, it comprises annular dust excluding hood 2, negative pressure pipe 3.The upper end of annular dust excluding hood 2 is connected with the bottom of ash bucket 1, and the cinder-discharging port of ash bucket 1 is enclosed within the annular dust excluding hood 2.Be provided with netted dust excluding hood 5 in the annular dust excluding hood 2, netted dust excluding hood 5 is arranged between the cinder-discharging port and negative pressure pipe 3 air inlets of ash bucket 1, and the lower end of netted dust excluding hood 5 is connected with the lower end of annular dust excluding hood 2.The mesh diameter of netted dust excluding hood 5 is 3-10mm.
One end of negative pressure pipe 3 be connected on the cover wall of annular dust excluding hood 2 and with annular dust excluding hood 2 in UNICOMs, deduster air inlet pipe 6 UNICOMs of the other end and dust pelletizing system make negative pressure pipe 3 form negative pressure (direction of arrow is the direction that air flows to the system dust removing device in the pipeline among the figure) during the deduster air inlet.Be provided with valve 4 in the negative pressure pipe 3.
The utility model example structure is simple, utilizes the equipment in the original system, need not existing equipment is carried out big change, and cost is low, can save expenses such as power consumption and maintenance.
Claims (4)
1, dust unloadnig apparatus final dusting device is characterized in that: it comprises annular dust excluding hood (2), negative pressure pipe (3); The upper end of annular dust excluding hood (2) is connected with the bottom of ash bucket (1), and the cinder-discharging port of ash bucket (1) is enclosed within the annular dust excluding hood (2); One end of negative pressure pipe (3) be connected on the cover wall of annular dust excluding hood (2) and with the interior UNICOM of annular dust excluding hood (2), the deduster UNICOM of the other end and dust pelletizing system.
