[0022] By adopting the above technical solution, when the first rotating shaft 21 rotates, it drives the main bevel gear 22 to rotate, and the main bevel gear 22 is respectively meshed with the two slave bevel gears 23, and then one of the slave bevel gears 23 drives the corresponding rotating rod 24 to rotate, and the other slave bevel gear 23 drives the corresponding hollow cylinder 25 to rotate in the opposite direction. With the coordinated use of the main bevel gear 22 and the two slave bevel gears 23, the stirring blades 26 on the rotating rod 24 and the stirring blades 26 on the hollow cylinder 25 are driven to rotate in opposite directions at the same time, so that the oil-water and oil-water separator in the box body 1 are stirred more fully, which is more conducive to the separation of oil and water. Then, under the action of the condensation plate 14, the oil is separated in the box body 1, and the sewage is directly separated and falls down and discharged from the water outlet 15.

[0024] By adopting the above technical solution, when the second rotating shaft 31 rotates, the spiral blades 32 are driven to rotate, and the spiral blades 32 transport impurities out of the discharge pipe 34 on the filter bin 3, thereby preventing the impurities from affecting the separation of oil and water.

[0026] By adopting the above technical solution, when the pump 4 is started, the waste oil in the sewage pool flows into the filter bin 3 from the cavity 42 and the conduit 41 .

[0027] The condensing plate 14 is inclined.

[0028] By adopting the above technical solution, it is more convenient to discharge the separated oil from the oil outlet pipe 13.

[0029] The hollow cylinder 25 is rotatably inserted in the box body 1 . The length of the hollow cylinder 25 is smaller than the length of the rotating rod 24 . The rotating rod 24 rotatably penetrates the hollow cylinder 25 .

[0030] A fixing seat 5 is fixedly installed on one side of the box body 1 close to the oil outlet 11, a threaded rod 51 is rotatably penetrated through the middle of the fixing seat 5, the outer thread of the threaded rod 51 is connected with a clamping block 52, the clamping block 52 is slidably clamped in the oil outlet pipe 13, a rotating wheel 53 is fixedly installed on the top of the threaded rod 51, and a plurality of evenly distributed anti-slip strips are fixedly installed on the outside of the rotating wheel 53.

[0031] By adopting the above technical solution, when the rotating wheel 53 is rotated, the threaded rod 51 is driven to rotate. As the threaded rod 51 rotates, the block 52 is driven to move upward, so that the oil in the box 1 flows out from the oil outlet pipe 13. At the same time, the anti-slip strip on the outside of the rotating wheel 53 increases the friction between the hand and the rotating wheel 53.

[0032] A motor 27 is fixedly mounted on the upper surface of the box body 1 , and a driving end of the motor 27 is fixedly mounted on the end of the first rotating shaft 21 . The first rotating shaft 21 is connected to the second rotating shaft 31 via a belt transmission.

At the same time, the belt connection between the first rotating shaft 21 and the second rotating shaft 31 drives the second rotating shaft 31 to rotate, thereby driving the spiral blade 32 to rotate.

[0034] Two groups of symmetrically distributed legs 101 are fixedly mounted at the four corners of the bottom end of the box body 1 .

[0035] By adopting the above technical solution, the box body 1 is supported to facilitate the outflow of sewage.

[0036] Working principle: When in use, first put the conduit 41 and the cavity body 42 into the sewage pool, start the pump 4, and suck the waste oil in the sewage pool into the filter bin 3 through the conduit 41. At the same time, the several holes on the cavity body 42 block the large impurities outside to avoid blocking the conduit 41. Then start the motor 27 to drive the first rotating shaft 21 to rotate. At the same time, the first rotating shaft 21 and the second rotating shaft 31 are connected by a belt drive to drive the second rotating shaft 31 to rotate. The second rotating shaft 31 drives the spiral blade 32 to rotate. The spiral blade 32 transports the impurities in the waste oil in the sewage pool out from the discharge pipe 34 on the filter bin 3, and the waste oil flows into the box 1 from the filter screen 33 and the feed port 12. Then, when there is a certain amount of waste oil in the sewage pool in the box 1, turn off the pump 4 and add the oil-water separator from the feed port.

[0037] At the same time, with the rotation of the first rotating shaft 21, the main bevel gear 22 is driven to rotate, and the main bevel gear 22 is respectively meshed with the two slave bevel gears 23, and then one of the slave bevel gears 23 drives the corresponding rotating rod 24 to rotate, and the other slave bevel gear 23 drives the corresponding hollow cylinder 25 to rotate in the opposite direction. With the cooperation of the main bevel gear 22 and the two slave bevel gears 23, the stirring blade 26 on the rotating rod 24 and the stirring blade 26 on the hollow cylinder 25 are driven to rotate in the opposite direction, so that the oil-water and the oil-water separator in the box body 1 are stirred more fully, which is more conducive to the separation of oil and water. Then, under the action of the coagulation plate 14, the oil is separated in the box body 1, and the sewage is directly separated and falls, and discharged from the water outlet 15;

[0038] When a fixed amount of oil is separated from the box body 1 , the rotating wheel 53 is rotated to drive the threaded rod 51 to rotate, so that the block 52 moves upward, and then the oil is discharged from the oil outlet pipe 13 .
