Title:
ASH DISCHARGE DEVICE WITH ASH OUTLET FOR BOILER
Document Type and Number:
WIPO Patent Application WO/2018/006409
Kind Code:
A1
Abstract:
An ash discharge device with an ash outlet for a boiler comprises an ash outlet (1). The ash discharge device further comprises a door frame (2) and a door frame casing (3). The door frame (2) communicates with the ash outlet (1), and a cylindrical worm screw (20) is disposed at a position where the door frame (2) communicates with the ash outlet (1). A recess (21) for mating with an external thread of the worm screw (20) and a motor (22) for driving rotation of the worm screw (20) are arranged at an inner wall of the door frame (2). A supporting frame (23) for supporting the motor (22) is connected to and disposed at the inner wall of the door frame (2). A through hole (230) for disposing wiring is arranged inside the supporting frame (23). A power supply (30) for supplying electric power to the motor (22) is disposed in a space formed between the door frame (2) and the door frame casing (3). An outer wall of the door frame casing (3) is provided with a control switch (31) for controlling the motor (22) to turn on and off. When ash is to be discharged, only the control switch (31) needs to be controlled to activate operation of the motor (22). Rotation of the worm screw (20) causes ash to be discharged from between the threads of the worm screw (20). When the worm screw (20) rotates, flowing air forms an air pressure flow, such that ash can be discharged fast and completely. The invention has a simple structure and low costs.
