[0029] As shown in Figure 1 , Figure 2 and Figure 4 , the present embodiment provides an aerobic tank with floating sludge interception and recovery structure, which comprises an aerobic tank 1 and a connecting frame 2 fixedly arranged on the outer walls of the two sides of the upper end of the aerobic tank 1, a floating sludge recovery assembly 3 is arranged between the connecting frames 2, the floating sludge recovery assembly 3 comprises a first motor 301 fixedly arranged on one end of the outer wall of the connecting frame 2, a first ball screw 302 is arranged on the output end of the first motor 301, a first ball screw sleeve 304 is sleeved on the outer wall of the first ball screw 302, a receiving frame 306 is arranged on the upper end of the first ball screw sleeve 304, a first air cylinder 307 is connected to the upper end of the receiving frame 306, an adjusting frame 308 is connected to the extension end of the first air cylinder 307, a mud removal frame 309 is connected to the lower end of the outer wall of the adjusting frame 308, and a second air cylinder 310 is connected to the upper end of the mud removal frame 309.

[0030] The floating sludge recovery assembly 3 further comprises first sliding rods 303 fixed between the connecting frames 2 and symmetrical to the first ball screw 302, one end of the first ball screw 302 away from the first motor 301 is rotationally connected with the connecting frame 2, and the outer wall of the first sliding rod 303 movably sleeved with a sliding sleeve 305, and the first ball screw sleeve 304 and the sliding sleeve 305 are fixedly connected with the lower end of the bearing frame 306.

[0031] The inner wall of the sludge removal frame 309 is rotationally connected with the adjusting frame 308 at both ends, the sludge removal frame 309 is movably inserted into the inner cavity of the aerobic tank 1, the outer wall of the sludge removal frame 309 is in close contact with the inner wall of the aerobic tank 1, the outer wall of the sludge removal frame 309 can slide along the inner wall of the aerobic tank 1, the upper end of the second cylinder 310 is hingedly connected with the middle part of the bottom end of the adjusting frame 308, and the extending end of the second cylinder 310 is hingedly connected with the upper end of the sludge removal frame 309.

[0032] The floating sludge recovery assembly 3 further comprises two groups of second sliding rods 311 movably inserted into the adjusting frame 308 at both ends and symmetrical to each other, and the upper end of the second sliding rod 311 is fixedly connected with the bearing frame 306.

[0033] When it is necessary to deal with the floating sludge in the aerobic tank 1, the first motor 301 is started to drive the first ball screw rod 302 to rotate, the first ball sleeve 304 slides along the first ball screw rod 302, and the first ball screw rod 302 drives the sludge removal frame 309 to reach one end on the upper side of the aerobic tank 1. The first motor 301 is turned off, and then according to the depth of the sewage in the aerobic tank 1 and the thickness of the floating sludge, the first cylinder 307 is started to drive the adjusting frame 308 to move downward, so that the sludge removal frame 309 slides downward along the inner wall of the aerobic tank 1 into the aerobic tank 1, so that the lower end surface of the sludge removal frame 309 moves below the water level of the sewage in the aerobic tank 1, and the bottom end of the sludge removal frame 309 is parallel to the water surface. In the process of moving the adjusting frame 308 and the sludge removal frame 309 downward under the drive of the first cylinder 307, the adjusting frame 308 slides downward along the second slide rod 311, so that the process of moving the adjusting frame 308 and the sludge removal frame 309 downward is more stable. After the sludge removal frame 309 moves to the appropriate position, the first motor 301 is started again, and the first motor 301 drives the first ball sleeve 304 to slide along the first ball screw rod 302, so that the sludge removal frame 309 moves along the water surface of the sewage in the aerobic tank 1 from one end of the aerobic tank 1 to the other end. Under the pushing of the sludge removal frame 309, the floating sludge gradually accumulates on the upper end of the sludge removal frame 309, until the front end of the sludge removal frame 309 abuts against the inner wall of the aerobic tank 1 and cannot continue to move. At this time, the first motor 301 is turned off, and the first cylinder 307 is started to recover, so that the sludge removal frame 309 drives the floating sludge to move upward until the floating sludge is completely removed from the aerobic tank 1. Then the first motor 301 is started again, so that the sludge removal frame 309 moves to the end of the first ball screw rod 302 until it cannot continue to move. At this time, the second cylinder 310 is started to recover, so that the two ends of the sludge removal frame 309 rotate upward by a certain angle along the adjusting frame 308, so that the sludge removal frame 309 is inclined downward, and the floating sludge falls from the upper end of the sludge removal frame 309. The above process is repeated until the floating sludge in the aerobic tank 1 is removed. The whole process does not need manual operation, not only the operation efficiency is high, but also the workers are away from the floating sludge, avoiding the influence of harmful substances in the floating sludge on people.

[0034] As Figure 1 , Figure 3 and Figure 5 shown in the drawings, the outer wall of the aerobic tank 1 has a water outlet 4 at one side of the lower end, and the inner cavity of the aerobic tank 1 is provided with a scraping assembly 9 at the bottom.

[0035] The outer wall of the aerobic tank 1 movably inserts a baffle 5 at one side of the water outlet 4, and the inner wall of the aerobic tank 1 has a mounting groove 6 matched with the baffle 5.

[0036] The scraping assembly 9 comprises a second motor 91 fixed on the outer wall of the aerobic tank 1, the output end of the second motor 91 is connected with a second ball screw 92, the second ball screw 92 is rotationally connected with the aerobic tank 1, a second ball screw sleeve 93 is sleeved on the outer wall of the second ball screw 92, a scraper 94 is arranged on the lower end of the second ball screw sleeve 93, the scraper 94 is movably inserted into the inner wall of the bottom end of the aerobic tank 1, the outer wall of the front and rear ends of the scraper 94 is attached to the inner wall of the aerobic tank 1, and the lower end of the scraper 94 is attached to the inner wall of the bottom end of the aerobic tank 1.

[0037] The filter plate 7 is movably inserted into the aerobic tank 1 between the second ball screw 92 and the water outlet 4.

[0038] The positioning rod 8 is fixed on the upper end of the filter plate 7, the positioning hole 10 matched with the positioning rod 8 is arranged on the upper end of the outer wall of the aerobic tank 1, and the end of the positioning rod 8 away from the filter plate 7 is movably inserted into the positioning hole 10.

[0039] Due to the slow flow of water, heavy solid suspended substances, including part of the sludge, will gradually be deposited at the bottom under the action of gravity, which is a manifestation of physical deposition, and some sludge will fall to the bottom of the aerobic tank 1 in the form of deposition. At this time, the positioning rod 8 at the upper end of the filter plate 7 is aligned with the positioning hole 10, the filter plate 7 is inserted into the aerobic tank 1, and the baffle 5 is pulled out of the installation groove 6. Without the obstruction of the baffle 5, the sewage in the aerobic tank 1 is discharged from the water outlet 4. In the process of discharging the sewage, the deposits in the sewage are blocked by the filter plate 7 and are intercepted in the aerobic tank 1. After the sewage is discharged, the positioning rod 8 can be lifted upward, the positioning rod 8 is pulled out of the positioning hole 10, the filter plate 7 is taken out of the aerobic tank 1, the second motor 91 is started to drive the second ball screw sleeve 93 to slide along the second ball screw 92, so that the scraper 94 slides along the bottom end of the aerobic tank 1, the scraper 94 pushes the deposits in the aerobic tank 1 to move towards the water outlet 4, and when the scraper 94 moves to the end of the second ball screw sleeve 93 away from the second motor 91, the scraper 94 pushes the deposits out of the water outlet 4. The deposits in the aerobic tank 1 can be removed to avoid affecting the next sewage treatment.
