Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a boiler that is easy to clean, including: a boiler casing 1, an automatic air extraction box 2, a furnace sleeve 6, an exhaust pipe 7, a mounting shell 8 and a mounting frame 11. The automatic air extraction box 2 includes an air extraction pipe, an air box control sensor, a vacuum check valve, a three-phase solenoid valve, an air extraction pump, etc. The boiler casing 1 is also equipped with a pressure gauge, a pressure switch, a water supply pipe, a water inlet pipe, a water shortage prevention temperature sensor, an overheat prevention temperature sensor, etc. The automatic air extraction box 2 and the like are widely used in the boiler field, so they are not described in detail.

[0026] The boiler casing 1 has a water supply pipe 3, a heating pipe 4 and a burner 5 on its side wall. The mounting housing 8 has a mounting ring 9 on its side wall and a sealing cover on its side wall. The mounting frame 11 has a treatment mechanism for treating dust inside the furnace sleeve 6. The treatment mechanism includes a movable frame 12 that is slidably connected to the inner wall of the mounting frame 11. The inner wall of the movable frame 12 is equipped with a drive housing 16 via a mounting rod 17. The inner wall of the drive housing 16 is equipped with a first motor 15. The output shaft of the first motor 15 is equipped with a scraper 13 via a connecting rod 14.
