Axle, helical blade, dust-proof catch, asbestos pad, bearing, bearing holder (housing, cover), flange, gear cover, gear, flange, water sealing stationary ring, water seal are moved
Ring, water seal catch, water pot, outlet pipe, water pot catch, burner hearth；Wherein,
Helical blade is welded with hollow axle, water inlet pipe in hollow axle, is provided with；Constitute between water inlet pipe end and hollow shaft end
It is jacket structured, it is ensured that cooling water circulation unobstructed；Water is entered by water inlet pipe, by way of hollow axle, is finally flowed out from outlet pipe；Hollow
Dust-proof catch, asbestos pad, bearing and bearing holder (housing, cover) are sequentially with axle；Gear and gear cover are further fixed on hollow axle, by method
It is blue to be determined with flange；Water sealing stationary ring is directly embedded in flange, and water seal movable ring is compressed with water sealing stationary ring by water seal catch and connected
Connect and be placed in water pot；Water seal catch is threaded connection and is fixed on hollow axle, and water pot catch is threaded connection and is fixed on
On water inlet pipe；Constitute between water seal catch and water pot catch jacket structured；Outlet pipe is fixedly connected with water pot；Helical blade is most
Bottom is provided with gap with burner hearth bottom.
Described water inlet pipe end is not less than the space of water inlet bore with the jacket structured of hollow shaft end.
Described water seal catch is not less than the space of water inlet bore with the jacket structured of water pot catch.
The bottommost of described helical blade is 10mm-30mm with burner hearth bottom gap.
The present invention has the advantage that relative to prior art and improves and is：Using water inlet pipe, hollow axle, helical blade etc.
It is jacket structured, the coke button in burner hearth is blended by helical blade and send burner hearth, it is ensured that the normal air-supply of burner hearth bottom, made
Fuel fully can burn, and solve coking problem；By water circulation reduce steel heating temperature, it is ensured that selection it is extensive
Property, without the need for resistant to elevated temperatures special material, common iron；Possess self-skimming function, the ashes that the fuel afterburnt produces lead to
The rotation for crossing helical blade is discharged out of the furnace together with the coke button for being blended.

Specific embodiment
By following examples further illustrate description the present invention, and never in any form limit the present invention, without departing substantially from
On the premise of the technical solution of the present invention, easily any of realization changes those of ordinary skill in the art made for the present invention
Dynamic or change is fallen within scope of the presently claimed invention.
According to Fig. 1, Fig. 2, the present invention includes：Water inlet pipe 1, hollow axle 2, helical blade 3, dust-proof catch 4, asbestos pad
5th, bearing 6, bearing holder (housing, cover) 7, flange 8, gear cover 9, gear 10, flange 11, water sealing stationary ring 12, water seal movable ring 13, water seal catch 14,
Water pot 15, outlet pipe 16, water pot catch 17, burner hearth 18, the grey passage 19 that falls, pit 20 are constituted；
