Helical structure composition automatic feeding (18) realizes feeding function, and another set of helical structure composition automatic coke removing device (10) is in fact
Now devoke function.
One end termination of feeding screw shape auger (18-1) is immediately entered outside combustion chamber (2) in the automatic feeding (18)
At material mouth, feeding screw shape auger (18-1) rotation section be located at it is outside in combustion chamber (2), feeding screw auger (18-1) it is another
Hold as connecting shaft form；The connecting shaft of feeding screw auger (18-1) other end passes through special bearing (18-5), passes through shaft coupling
(18-3) connects with self-feeding motor (14) output shaft.
The special bearing (18-5) is thick tubular, and fixing hole, special axle are provided with special bearing (18-5) circumference
Hold the inner ring that (18-5) is fixed on tubular frame (18-2).
The self-feeding motor (14) is fixed on tubular frame (18-2) axial end by motor mounting plate (18-4)
On.
The automatic coke removing device (10) send one end termination of decoking screw auger (11) to be located at going out for combustion chamber (2) inwall
At material mouth, decoking screw auger (11) rotation section is placed on combustion chamber (2) inside, and the other end of decoking screw auger (11) is to connect
Spindle form；The connecting shaft of decoking screw auger (11) passes through special bearing, passes through shaft coupling and self-feeding motor output shaft
Connection.
Decoking screw auger (11) the rotation segment length matches with combustion chamber (2) inner wall size.
The operation principle of the present invention：After combustor starts, PLC automatically controls startup, and self-feeding motor is started working, sent
Expect helical form auger 18-) concomitant rotation, deliver fuel in combustion chamber 2, automatic ignition device work, light fuel, sidepiece
Centrifugal blower 3 start, will wind be sent into combustion chamber scholar in it is combustion-supporting, after certain time automatic coke removing device start working, devoke spiral shell
The waste residue that rotation auger 11 rotates after combustion chamber 2 is burnt is released outside combustion chamber 2.
Present invention decoking screw auger (11) is identical with the connecting shaft form of feeding screw shape auger (18-1), is all connection
Axle passes through special bearing, is connected by shaft coupling with self-feeding motor output shaft.
The beneficial effects of the invention are as follows：A kind of simple in construction, peace is provided by tubular frame and special thick tubular bearing
Convenient double helix automechanism is filled, spiral automatic feed, spiral automatic decoking mechanism individually connect respective motor in structure,
Controlled respectively by PLC, its is simple in construction, easy to control, the trouble for avoiding linkage installation control from bringing.
The present invention simplifies existing burner structure, reduces equipment volume, saves space, is realized and closed using tubular rack construction
Dust-proof, the protection of key parts, while because reducing whole set equipment cost reducing the use of parts.
