A fan blade 209 is fixedly installed on the outer side of the rotating rod 202, which can feed the purified ash powder into the mounting cylinder 1 through the feed pipe 8. A steam generator is connected through the connecting pipe 206 to introduce steam into the air outlet ring 204. The exhaust head 205 sprays air onto the bottom of the heating plate 208 to heat the heating plate 208. The heating plate 208 heats and dries the purification ash accumulated on the heating plate 208, reducing the agglomeration and stickiness of the purification ash, making it easier to transport. The water vapor of the purification ash is discharged through the exhaust pipe 6. The motor 201 is started, which drives the rotating rod 202 to rotate, causing the scraper 203 to rotate and remove the purification ash attached to the top of the heating plate 208. The fan blades 209 are driven to rotate and accelerate the steam to be discharged.

[0017] The explosion-proof mechanism 3 includes an installation pipe 301, a fixed pipe 302, a moving ring 303, a moving cylinder 304, an electromagnet 305, a baffle 306, a pressure ring 307, a magnet 308, an air outlet ring 309, an air outlet duct 310, and an air guide pipe 311. The top of the installation cylinder 1 has a discharge port. A set of installation pipes 301 is fixedly installed inside the discharge port. A fixed pipe 302 is fixedly installed on the outer side of the set of installation pipes 301. Another set of installation pipes 301 is fixedly installed on the inner side of the fixed pipe 302. An electromagnet 305 is fixedly installed on the inner side of the fixed pipe 302. An installation ring is fixedly installed on the inner side of the electromagnet 305. Four sets of... Inside the baffle 306 and the fixing tube 302, a movable ring 303 and a pressure ring 307 are provided. The movable ring 303 is located below the electromagnet 305, and the pressure ring 307 is located above the electromagnet 305. A movable cylinder 304 is fixedly installed inside the movable ring 303. The top of the movable cylinder 304 is in contact with the bottom of the baffle 306. A set of magnets 308 is fixedly installed on the top of the movable ring 303, with the top of the set of magnets 308 being the positive pole. Another set of magnets 308 is fixedly installed on the bottom of the pressure ring 307, with the bottom of the other set of magnets 308 being the positive pole. An air outlet ring 309 is fixedly installed inside the mounting cylinder 1, and an opening is provided on the outer side of the air outlet ring 309. Multiple air outlets are provided, with an air outlet duct 310 fixedly installed inside each outlet. Air inlets are opened on the outer sides of the air outlet ring 309 and the mounting cylinder 1, with a guide pipe 311 fixedly installed inside each inlet. By controlling the closing of the valve 7 inside the exhaust pipe 6, an air pump is connected through the guide pipe 311 to blow inert gas into the air outlet ring 309, causing the air outlet duct 310 to blow the purified ash into the air, raising the ash. The fan blades 209 rotate to transport the purified ash upwards, allowing it to enter the mounting pipe 301. The activation of the electromagnet 305 causes its bottom to become the negative pole, attracting a set of magnets 308 and moving the moving ring 303 upwards. The moving cylinder 304 moves to push the baffle 306 to rotate and convey the purified ash. After the conveying is completed, the electromagnet 305 is activated, so that the top of the electromagnet 305 is the negative pole. A set of magnets 308 and the bottom of the electromagnet 305 repel each other, causing the set of magnets 308 to separate from the electromagnet 305. The baffle 306 rotates to a horizontal position and attracts the other set of magnets 308, which drives the pressure ring 307 to move, so that the bottom of the pressure ring 307 is in contact with the top of the baffle 306 to prevent the baffle 306 from rotating. In the event of an explosion in the pipeline, the explosion wave can be blocked, and heat can be prevented from being conducted into the installation cylinder 1, thus preventing the explosion of the purified ash in the installation cylinder 1.

[0018] Furthermore, an exhaust port is provided at the top of the installation cylinder 1, and an exhaust pipe 6 is fixedly installed inside the exhaust port. A drain port is provided at the bottom of the installation cylinder 1, and a water guide pipe 5 is fixedly installed inside the drain port. A valve 7 is fixedly installed inside the water guide pipe 5 and the exhaust pipe 6. An inlet port is provided on the outside of the installation cylinder 1, and an inlet pipe 8 is fixedly installed inside the inlet port, thereby reducing safety hazards and improving the effectiveness of the device.

[0019] Working principle: Purified ash powder is fed into the installation cylinder 1 through the feed pipe 8. A steam generator is connected through the connecting pipe 206, and steam is introduced into the exhaust ring 204, causing the exhaust head 205 to spray out towards the bottom of the heating plate 208, heating the heating plate 208. The heating plate 208 heats and dries the purified ash accumulated on it, reducing caking and adhesion, facilitating its transport. Water vapor from the purified ash is discharged through the exhaust pipe 6. Starting the motor 201 drives the rotating rod 202, causing the scraper 203 to rotate and remove the purified ash adhering to the top of the heating plate 208. The fan blades 209 rotate to accelerate the steam discharge, improving the device's service life. By controlling the closure of the valve 7 inside the exhaust pipe 6, an air pump is connected through the air guide pipe 311, blowing inert gas into the exhaust ring 309, causing the exhaust pipe 310 to blow the purified ash out, raising it. The rotating fan blades 209 further contribute to the drying process. The purified ash is conveyed upwards into the installation pipe 301. The electromagnet 305 is activated, making its bottom negative pole. This attracts a set of magnets 308, causing the moving ring 303 to move upwards. This moves the moving cylinder 304, pushing the baffle 306 to rotate and convey the purified ash. After conveying, the electromagnet 305 is activated again, making its top negative pole. The magnets 308 repel the bottom of the electromagnet 305, causing them to separate. The baffle 306 rotates to a horizontal position, attracting another set of magnets 308. This moves the pressure ring 307, bringing its bottom into contact with the top of the baffle 306, preventing the baffle 306 from rotating. In the event of an explosion within the pipe, this can block the blast wave, preventing heat conduction into the installation cylinder 1 and thus preventing the purified ash inside the installation cylinder 1 from exploding, reducing safety hazards and improving the device's effectiveness.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
