[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 An automatically filling methanol evaporator includes a methanol evaporator body 1, an automatic filling assembly 2 on one side of the methanol evaporator body 1, the automatic filling assembly 2 including a methanol holding tank 201, an electric valve 203 connected to one side of the methanol evaporator body 1 via a flange, an outlet pipe 202 connected to the other end of the electric valve 203 via a flange, the methanol holding tank 201 connected to one end of the outlet pipe 202 via a flange, when the electric valve 203 is opened, methanol in the methanol holding tank 201 flows into the methanol evaporator body 1 through the outlet pipe 202 and the electric valve 203, a connecting pipe 204 connected to one side of the methanol evaporator body 1 via a flange, an ultrasonic level gauge 205 inserted into the top end of the connecting pipe 204, thereby detecting the liquid level in the methanol evaporator body 1;

[0024] A filter assembly 3 is provided on the top of the methanol evaporator body 1. The filter assembly 3 includes a connecting shell 301, which is fixed to the top of the methanol evaporator body 1 by bolts. The top and bottom of the connecting shell 301 are provided with multiple through holes. A rotating shaft 302 is rotatably inserted through the top and bottom of the connecting shell 301. A motor 10 is fixed to the top outer wall of the connecting shell 301 by bolts. The output end of the motor 10 is fixedly connected to the top of the rotating shaft 302. Multiple rotating discs are welded to the outer wall of the rotating shaft 302. 303 is located inside the connecting shell 301. A demist filter 304 is snapped into the rotating disk 303. Driven by the motor 10, the rotating shaft 302 rotates, thereby driving multiple rotating disks 303 to rotate, which in turn drives multiple demist filters 304 to rotate. The used demist filter 304 is then removed and replaced with a new one. The demist filter 304 is positioned opposite to the through hole. Methanol gas passes through the demist filter 304, removing droplets from the methanol vapor and keeping the methanol vapor dry so that it is discharged from the vapor outlet.

[0025] Sealing rings 305 are bonded to the top and bottom of the rotating disk 303. The two sealing rings 305 contact the inner top and bottom walls of the connecting shell 301 respectively, thus preventing methanol leakage. A top cover 4 is bolted to the outer top wall of the connecting shell 301, located above one of the through holes. A controller 206 (model DATA-7311) is bolted to the outer wall of one side of the methanol evaporator body 1. The controller 206 is electrically connected to the electric valve 203, the ultrasonic level gauge 205, and the motor 10. Multiple sealing covers 5 are rotatably connected to the outer top wall of the connecting shell 301. An upper transparent plate 8 is snapped into the sealing cover 5, and the sealing cover 5 covers the remaining... Above the three demister filters 304, a threaded rod 6 is rotatably connected to the outer circumference of the connecting shell 301. One end of the threaded rod 6 is engaged with one side of the sealing cover 5. A wing nut 7 is threaded onto one end of the threaded rod 6. By unscrewing the wing nut 7 and then turning the threaded rod 6 to separate it from the sealing cover 5, the sealing cover 5 can be opened, making it easy to replace and clean the demister filters 304. A lower transparent plate 9 is engaged in the three through holes at the bottom of the connecting shell 301. A support rib 11 is fixed to the bottom outer wall of the connecting shell 301 by bolts. The other side of the support rib 11 is fixedly connected to one side of the methanol evaporator body 1, thereby strengthening the connection between the connecting shell 301 and the methanol evaporator body 1.

[0026] The working principle of this embodiment is as follows: When in use, the electric valve 203 is opened, and the methanol in the methanol container tank 201 flows into the methanol evaporator body 1 through the liquid outlet pipe 202 and the electric valve 203. The liquid level in the methanol evaporator body 1 is detected by the ultrasonic level gauge 205. When the ultrasonic level gauge 205 detects that the liquid level in the methanol evaporator body 1 has reached the set value, it transmits the information to the controller 206. Then, the controller 206 controls the electric valve 203 to close, pausing the addition of methanol. Then, the methanol is evaporated through the methanol evaporator body 1, thereby evaporating the methanol liquid into gas. The methanol gas rises upward, and the methanol gas passes through the defoaming filter 304 to remove the liquid droplets in the methanol vapor, keeping the methanol vapor dry and discharged from the steam outlet.

[0027] When the demister filter 304 needs to be replaced, start the motor 10. Driven by the motor 10, the rotating shaft 302 rotates, thereby driving multiple rotating discs 303 to rotate, which in turn drives multiple demister filters 304 to rotate. Then, remove the used demister filter 304 and replace it with a new one. Then, unscrew the wing nut 7, and then turn the threaded rod 6 to separate it from the sealing cover 5. Then, open the sealing cover 5 to facilitate the replacement and cleaning of the demister filter 304.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
