Technical field

The present invention relates to a kind of rotary drum dust-extraction unit, refer specifically to air-introduced machine dust accumulation and will not remove convenient for the rotary drum disassembled Dirt device.

Background technology

Ventilation and dust removal are all essential in many industrial productions, and what application was more at present is cyclone dust removal, Bag filter Dedusting and pulsed dedusting, wherein cyclone dust removal due to simple in structure, durable, failure rate are low and it is relatively broad to apply, but deposit Very thorough dedusting can not be realized efficiency of dust collection is not very high, separation factor is smaller；Cloth-sack-type dust removal is filtering type, effect It is good, but air drag is larger during use, and wind pressure is high, and energy consumption is larger；Pulsed dedusting energy consumption is relatively low, good dedusting effect, but Structure is complex, and manufacture is of high cost.Therefore, there is an urgent need to there is a kind of dust-extraction unit in industrial production, above-mentioned three kinds can be taken into account The characteristics of the advantages of dust-extraction unit, with good dedusting effect, low energy consumption, and structure is also relatively simple.

Air-introduced machine is the key equipment of dust-extraction unit, and air-introduced machine is generally centrifugal blower, air-introduced machine it is continuous, stable, can Very crucial by work, since the occasion that dust-extraction unit uses all contains certain dust mostly, when air-introduced machine works, air-flow leads to Since centrifugation, dust granule can depart from air-flow phase and deposit and be attached to wind turbine leaf when crossing high-speed rotating draught fan impeller On wheel.

Draught fan impeller rotating speed is generally all higher, as long as can all be accumulated after working long hours with the presence of micro dust in air-flow More dust is tired out, so as to change the balance of draught fan impeller rotation, if draught fan impeller does not have dust self purification not have yet Have timely cleaning, will static and dynamic equilibrium cumulative and that draught fan impeller is altered in steps, so as to generate vibration.Once The dust that running into has part hardened, which is vibrated, to come off, and the dynamic rotary away from air-introduced machine will balance, then generate strong immediately Vibration, this may trigger serious personnel and equipment safety accident.

On the other hand, the structure of common wind turbine is typically all that fan shaft one end is draught fan impeller, and the other end is electronic motor-driven Power input terminal is often shaft coupling.Since wind turbine is typically all continuous operation for a long time, so bearing is fragile, bearing one is replaced As need first to dismantle the shaft coupling of draught fan impeller and the other end, but the assembling of existing fan shaft and draught fan impeller, shaft coupling belongs to Typical axis, hole interference fit, and carrying transmission is carried out by key.It is higher to be interference fitted usual requirement on machining accuracy, and Realize torque bearing function with reference to key connection, assembling generally all needs to load very big extruding force, if without professional equipment with Instrument, dismounting are all very inconvenient.

Being threadedly coupled has that processing is simple, assembling is convenient, while also has unidirectional carrying torque functions, therefore, in wind turbine If axis is threadedly coupled with that can be used in the connection in hole and realizes transmission, it is all more convenient to be allowed to assembly or disassembly, then possesses higher Practical value and market application foreground.In actual axis is assembled with hole cooperation motion thread, in order to realize big carrying work( Energy demand, the scantling of thread spindle similar nut member with what is matched is all larger, is screwed in assembling often all also very light Pine is convenient, and can realize the automatic continuous locking of bearing capacity in use, thus very reliable, but in dismounting, assembling Often very tight, dismounting is very difficult, if simple easy removal can be realized under these conditions, it appears particularly important.
