[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3In the embodiment of the present utility model, an air intake duct cleaning mechanism includes a reaction chamber 1, a horizontal air intake duct 3 and a vertical air intake duct 4. Several horizontal air intake ducts 3 are installed on the circumference of the side wall of the reaction chamber 1, and the vertical air intake duct 4 is installed on the horizontal air intake duct 3. An end cover 5 is installed at the end of the horizontal air intake duct 3 away from the reaction chamber 1, and a motor 6 is installed on the end cover 5. The motor 6 is externally connected to a PLC controller and can be operated at a scheduled time. The operating time and operating interval can be manually set. The output shaft of the motor 6 is fixedly connected to a turntable 7 arranged in the horizontal air intake duct 3. A scraper 8 is installed on the turntable 7. The motor 6 can drive the scraper 8 to rotate on the inner wall of the horizontal air intake duct 3 through the turntable 7 to scrape off the dust on the inner wall of the horizontal air intake duct 3, thereby preventing the dust from clogging the air intake duct and causing the equipment to be unable to operate;

[0020] A chassis 2 is installed at the bottom of the reaction chamber 1. A mounting hole 10 is provided on the chassis 2. The mounting hole 10 is provided to facilitate connection between the chassis 2 and the water tank.

[0021] One side of the scraper 8 is in contact with the inner wall of the transverse air inlet duct 3. This design enables the scraper 8 to scrape away the dust on the inner wall of the transverse air inlet duct 3.

[0022] The length of the scraper 8 is equal to the length of the transverse air intake duct 3 . This design enables the scraper 8 to completely scrape away dust from the inner wall of the transverse air intake duct 3 .

[0023] See also Figure 1-2 A nitrogen connector 9 is provided on the end cover 5, and the nitrogen connector 9 is externally connected to a nitrogen purge instrument. The nitrogen connector 9 is provided on the end cover 5 directly below the motor 6. This is because the dust will fall to the bottom of the transverse air intake pipe 3 under the action of gravity after being scraped from the inner wall of the transverse air intake pipe 3. This design can make the dust in the transverse air intake pipe 3 more thoroughly removed. The nitrogen purge instrument is externally connected through the nitrogen connector 9, and the nitrogen purge instrument blows air into the transverse air intake pipe 3 through the nitrogen connector 9, and blows the dust scraped by the scraper 8 into the reaction chamber, so that the dust can be quickly blown out of the air intake pipe, thereby improving the efficiency of pipeline cleaning.

[0024] The working principle of this utility model is:

[0025] During use, the motor 6 drives the scraper 8 to rotate along the inner wall of the transverse air inlet duct 3 through the turntable 7. During the rotation, the dust on the inner wall of the transverse air inlet duct 3 is scraped off, and the dust falls to the bottom of the transverse air inlet duct 3 under the action of gravity. Then the external nitrogen purge device is turned on to blow air into the transverse air inlet duct 3 through the nitrogen connector 9. The dust is blown away from the transverse air inlet duct 3 by the nitrogen and falls into the reaction chamber 1, thereby completing the cleaning of the air inlet duct.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
