Specific embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing：
It please refers to Fig.1 and Fig. 2, a kind of rotatable hiding air knife ash-clearing structure including bearing block 1, bearing, shaft 3, turns over
Turn driving motor 4, air knife 5.In the present embodiment, bearing block 1 is fixed on 2 both sides of clack box of sorting equipment, clack box 2 by fastener
The upper several gas ports laid with the axis direction along the shaft 3, the dust stratification at this gas port are the removing target of mechanism.
The shaft 3 is mounted on by the bearing on the bearing block 1, i.e. the both ends of shaft 3 are matched respectively by bearing
On the bearing block 1.The turn drive motor 4 is fixed on the bearing block 1, the turn drive motor 4 it is defeated
Shaft couples with the shaft 3.The air knife 5 is fixed in the shaft 3.The air knife 5 is along the axis side of the shaft 3
To the extrusion of stretching.On the air knife 5 have along the shaft 3 axis direction extend, from one end of air knife penetrate through into
Air admission hole 5-1 inside the air knife 5.Several venthole 5- are evenly equipped in the extending direction of air knife 5 described in 5 upper edge of air knife
2, the outgassing direction of the venthole 5-2 is vertical with the axis of the shaft 3.In order to enable the pressure-air of venthole 5-2 accurate
It is directed toward dust accumulation surface, there is arc guide face 5-3 close to the exit of the venthole 5-2 on the air knife 5.
The work of turn drive motor 4 can drive the air knife 5 to overturn.It can be realized out by the rotary movement of air knife 5
Surface where the gas port of the outgassing direction alignment clack box 2 of stomata 5-2.Optimal distances of the venthole 5-2 of air knife 5 away from above-mentioned surface
For 10mm.It is respectively that air knife packs up hidden state and wind that air knife 5 is overturn 180 ° of two extreme positions by turn drive motor 4
The working condition of knife 5.In the present embodiment, the upset motor 4 is angle stroke motor.
Working condition, the air admission hole 5-1 in this structure connect an air inlet pipe.When needing deashing, 4 work of turn drive motor
Make and air knife 5 is driven to rotate 180 °, air knife 5 is enabled to enter " work " state under " hide and pack up " state.
Air inlet pipe imports high pressure gas (pressure is about 0.55MPa-0.85MPa) into air admission hole 5-1, and high pressure gas passes through
Air-flow is generated by the gas chamber of air admission hole 5-1 and venthole the 5-2 special tectonic formed to spray from the venthole 5-2 on air knife 5.By
In coanda operation principle, high pressure gas can suck the surrounding air on 20-30 times of periphery when being sprayed from the venthole 5-2 of air knife 5,
Make air-flow more powerful, it is more efficient.The high pressure draught generated at the venthole 5-2 of air knife 5, dust stratification coal slime is blown off, is blown clearly
Time is about 30 seconds, and in the process, air knife 5 overlaps depth as 5mm with shedding track.After the completion of deashing, turn drive motor 4
Air knife 5 is driven to invert 180 °, air knife 5 enters hiding off working state at this time, avoids shed track completely.
In the present embodiment, the concrete structure of air knife 5 is：The air knife 5 is by air knife ontology 5-4, cover board 5-5 and fastener structure
Into cover board 5-5 is fixed on by the fastener on the air knife ontology 5-4, and the cover board 5-5 contacts the air knife ontology 5-
The extending direction of air knife 5 described in 4 face upper edge is evenly equipped with several air slots, and the air slot is in the air knife ontology 5-4 and institute
It states and forms the venthole 5-2 between cover board 5-5.Exit on the air knife ontology 5-4 close to the venthole 5-2 has
Arc guide face 5-3.
Embodiment described above is only that the preferred embodiment of the utility model is described, not new to this practicality
The conception and scope of type is defined, without departing from the design concept of the present utility model, ordinary skill skill in this field
Art personnel should all fall into the scope of protection of the utility model to all variations and modifications that the technical solution of the utility model is made,
The claimed technology contents of the utility model, are all documented in technology claim.
