Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a rotary flue ash discharging valve comprises a boiler 1, a bearing platform 2 and rotating plates 11, wherein an ash bucket 3 is fixedly connected to the lower surface of the boiler 1, the ash bucket 3 is inserted into the bearing platform 2, the bearing platform 2 is fixedly connected with the ash bucket 3, electromagnetic valves 9 are fixedly connected to the middle portions of two sides of the inner wall of the ash bucket 3 through bolts, one end of the ash bucket 3 is fixedly connected with an ash discharging pipe 12, a motor 7 is fixedly mounted on one side of the ash discharging pipe 12, the power output end of the motor 7 penetrates through the ash discharging pipe 12 and is fixedly connected with a fixing rod 10 through bolts, a plurality of rotating plates 11 are uniformly connected to the periphery of the fixing rod 10 at intervals, a controller 5 is fixedly connected to one side of the boiler 1 through bolts, the controller 5 is typically electrically connected with an external power supply, and the motor 7 and the electromagnetic valves 9 are electrically connected with the controller 5, one side of ash bucket 3 is pegged graft and is had nitrogen gas pipe 6, nitrogen gas pipe 6 with ash bucket 3 fixed connection, nitrogen gas pipe 6's the other end and nitrogen gas source sealing connection, the lower surface four corners department of cushion cap 2 all is through bolt fixedly connected with supporting leg 4, rotor plate 11 is equipped with threely altogether, rotor plate 11 with the inner wall of ash discharge pipe 12 contacts.
