[0021] Please see Figure 1-3 This utility model provides a technical solution: a mud circulation tank that is easy to clean, including a tank body 1. A first turnover box 2 is fixedly installed on one outer wall of the tank body 1, and a discharge port is opened at the bottom of the first turnover box 2. A second turnover box 12 is fixedly installed on the other outer wall of the tank body 1. A feed inlet is opened on one side of the tank body 1, and a filter screen 6 is fixedly installed inside the feed inlet. A first suction pump 3 is fixedly installed on the top outer wall of the first turnover box 2. A first feeding pipe 4 is fixedly installed on one side of the first turnover box 2, and one end of the first feeding pipe 4 is connected to the first suction pump 3. The output end of pump 3 is fixedly connected, and the input end of the first pump 3 is fixedly connected to the first pump pipe 5. It also includes a stirring assembly set on the tank 1, the first turnover box 2, and the first pump 3. The stirring assembly is used to stir the mud inside the tank 1. The rotating plate 11 set on the outside of the stirring assembly is used to clean the impurities filtered out by the filter screen 6 through the cooperation of the stirring assembly and the rotating plate 11. The water supply unit set on the second turnover box 12 is used to clean the inside of the tank 1 through the cooperation of the stirring assembly and the water supply unit.
[0022] Furthermore, the stirring assembly includes a hollow rotating shaft 7, a hollow rod 8, and a motor 9. The hollow rotating shaft 7 is rotatably mounted on both sides of the tank 1 and one side of the first turnover box 2. The hollow rod 8 is fixedly mounted on the front and rear sides of the hollow rotating shaft 7, and the hollow rod 8 communicates with the interior of the hollow rotating shaft 7. The motor 9 is fixedly mounted on the outer wall of one side of the first turnover box 2. The output shaft of the motor 9 is fixedly mounted to one end of the hollow rotating shaft 7. The hollow rotating shaft 7 and the hollow rod 8 are provided with nozzles. When the motor 9 is started, the output shaft of the motor 9 drives the hollow rotating shaft 7, the hollow rod 8, the scraper 10, and the rotating plate 11 to rotate. The rotation of the scraper 10 stirs the mud inside the tank 1, while the rotation of the rotating plate 11 pushes the impurities filtered out by the filter screen 6, rotating the impurities to above the discharge port of the first turnover box 2. The impurities are discharged through the discharge port, ensuring the filtration effect of the filter screen 6.
[0023] Furthermore, the water supply unit includes a second pump 13, a second feed pipe 14, and a second extraction pipe 15. The second pump 13 is fixedly installed on the top outer wall of the second turnover box 12, and the second feed pipe 14 is fixedly installed on one side of the second turnover box 12. One end of the second feed pipe 14 is fixedly connected to the output end of the second pump 13, and one end of the second extraction pipe 15 is fixedly installed to the input end of the second pump 13. When the second pump 13 is started, it extracts clean water through the second extraction pipe 15. The clean water sequentially passes through the second extraction pipe 15, the second pump 13, the second feed pipe 14, and the second turnover box 12 into the hollow shaft 7 and the hollow rod 8. Finally, the clean water is sprayed into the tank 1 through the nozzles on the hollow shaft 7 and the hollow rod 8 to clean the inner wall of the tank 1.
[0024] Furthermore, a scraper 10 is fixedly installed at one end of the hollow rod 8, and the scraper 10 is in contact with the inner wall of the tank body 1.
[0025] Furthermore, eight sets of rotating plates 11 are fixedly installed on the outer wall of the hollow rotating shaft 7 in a circular array, and the rotating plates 11 are located inside the first rotating box 2.

[0028] Furthermore, a support frame 17 is fixedly installed on the bottom outer wall of the tank body 1, and four sets of casters 18 are movably installed on the bottom of the support frame 17.
[0029] Working principle: By starting the first pump 3, the first pump 3 draws slurry through the first pump pipe 5. The slurry sequentially passes through the first pump pipe 5, the first pump 3, and the first feed pipe 4 into the inner wall of the first transfer box 2. The slurry inside the first transfer box 2 passes through the filter screen 6 into the tank 1, where impurities are filtered out. The motor 9 is then started. The output shaft of the motor 9 drives the hollow shaft 7, hollow rod 8, scraper 10, and rotating plate 11 to rotate. The rotation of the scraper 10 agitates the slurry inside the tank 1. The rotation of the rotating plate 11 is used to push the impurities filtered out by the filter screen 6, rotating the impurities to above the discharge port of the first turnover box 2. The impurities are discharged through the discharge port. By starting the second suction pump 13, the second suction pump 13 draws clean water through the second suction pipe 15. The clean water enters the hollow rotating shaft 7 and hollow rod 8 through the second suction pipe 15, the second suction pump 13, the second feeding pipe 14, and the second turnover box 12 in sequence. Finally, the clean water is sprayed into the tank 1 through the nozzles on the hollow rotating shaft 7 and hollow rod 8 to clean the inner wall of the tank 1.
