[0002] Septic tanks, as key facilities for treating domestic sewage and excrement, are widely used in urban and rural construction. Their main function is to preliminarily decompose and settle organic matter in sewage to reduce the pressure on subsequent sewage treatment. However, with population growth and the acceleration of urbanization, the treatment of septic tank cleaning materials and sediment has become an urgent problem to be solved.

Fan 12 rotates; a sealing plate 13 that matches the positioning plate is installed on the output shaft of the first motor 10, and an intake fan 12 is installed on the output shaft of the second motor 11. The intake fan 12 facilitates the extraction of air into the interior of the main body 1; two filter plates 8 are installed at the upper end of the filter cartridge 7. The filter plates 8 facilitate the filtration of harmful gases in conjunction with activated carbon; and an exhaust pipe is connected to the side of the filter cartridge 7. The other end of the exhaust pipe communicates with the cavity. Activated carbon is placed between the two filter plates 8, and an air purification reagent is placed at the lower end of the filter cartridge 7.

[0022] In this invention, the stirring mechanism includes a third motor 14 mounted on the top surface of the main body 1 and a rotating shaft 17 rotatably mounted in the top center of the cavity via a sealed bearing. The rotating shaft 17 facilitates the rotation of the first scraper 18, the second scraper 24, and the wall-breaking spiral 19. The third motor 14 facilitates the rotation of the rotating shaft 17. A drive gear 15 is mounted on the output end of the third motor 14, and a driven gear 16 meshes with one side of the drive gear 15. The drive gear 15 drives the driven gear 16, which in turn drives the rotating shaft 17. The center of the driven gear 16 is connected to the rotating shaft 17. Two first scrapers 18 are mounted in the middle of the rotating shaft 17, which cooperate with the guide plate 2. The first scrapers 18 can scrape off the raw materials adsorbed on the inner wall of the guide plate 2. Two sets of stirring rods 20 are mounted on the lower end of the first scrapers 18, and a wall-breaking spiral 19 is installed between the two sets of stirring rods 20. The wall-breaking spiral 19 prevents blockage at the lower opening of the guide plate 2. The wall-breaking spiral 19 is located at the lower opening of the guide plate 2.

The other end of the discharge port 22 passes through the reaction chamber 4 and the main body 1 and is located outside the main body 1. A second solenoid valve 23 is installed on the discharge port 22, which facilitates the opening and closing of the discharge port 22. Multiple heating rods 25 are installed at equal intervals on the inner wall of the cavity, which facilitates the heating of the reaction chamber 4. The heating rods 25 are at the same horizontal height as the reaction chamber 4.

[0023] Working principle: When using this utility model, first power on the device, then open the first solenoid valve 26, and feed the septic tank material into the main body 1 through the discharge port 6. The material enters the inverted cone-shaped guide plate 2 through the inverted cone-shaped discharge trough. Start the third motor 14, and the drive gear 15 installed at its output end rotates. Because the drive gear 15 meshes with the driven gear 16, the rotation of the drive gear 15 drives the driven gear 16 and the rotating shaft 17 to rotate. The two first scrapers 18 installed in the middle of the rotating shaft 17 rotate with the rotating shaft 17 to scrape the inner wall of the guide plate 2 to avoid material residue. The two sets of stirring rods 20 installed at the lower end of the first scraper 18 and the wall-breaking spiral 19 located at the lower opening of the guide plate 2 also rotate synchronously to stir and break the wall of the material, so that the material is evenly dispersed, which is convenient for subsequent pyrolysis and carbonization reaction.

[0024] The heating rod 25 on the inner wall of the cavity is at the same horizontal height as the reaction chamber 4. When the heating rod 25 is activated, a high-temperature environment is provided for the cavity. The pre-treated material enters the reaction chamber 4 and undergoes a pyrolysis and carbonization reaction under high-temperature conditions, converting organic matter into solid carbon, combustible gas and other products.

[0025] During the pyrolysis and carbonization process, part of the gas produced is discharged through the air inlet 27 at the top of the main body 1. The first motor 10 is started, which controls the rotation of the sealing plate 13 and adjusts the opening degree of the air inlet 27. The second motor 11 is started, which drives the air intake fan 12 to rotate, accelerating the gas flow. The discharged gas enters the filter cartridge 7, and the gas is filtered by the filter plate 8, adsorbed by activated carbon, and purified by air purification reagent in sequence to reduce the emission of harmful gases. The purified gas is discharged to the designated location through the exhaust pipe connected to the side of the filter cartridge 7.

[0026] After the pyrolysis and carbonization reaction is completed, the fourth motor 21 installed inside the base 5 is started. The inclined second scraper 24 installed at its output end rotates, which can scrape the material in the reaction chamber 4 toward the discharge port 22. The second solenoid valve 23 installed on the discharge port 22 is opened, and the material is discharged from the outside of the main body 1 through the discharge port 22, completing the entire pyrolysis and carbonization process. In addition, a pressure relief valve 9 is installed on the side of the main body 1, which can be opened when the pressure in the cavity is abnormal to ensure the safe operation of the device. Finally, the power supply is disconnected.

[0027] 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.
