The support bar 4 is rotatably mounted with a support plate 5. The support plate 5 is fixedly mounted on the top side of the partition plate 1. And the water guide tank body 3 is rotated, so that the water guide tank body 3 faces one standing tank 2, and after oily wastewater is discharged into the water guide tank body 3, the oily wastewater flows into the standing tank 2 under the guidance of the inclined direction of the water guide tank body 3.

Referring to fig. 2 and 3, the water guide tank 3 has a first driving mechanism 6 at one end and a second driving mechanism 7 at the other end. The first driving mechanism 6 includes a first slider 61, a jack 62, and a first slider 63. The first slider 63 is fixedly mounted to a side wall of the first slider 61, and the jack 62 is fixedly mounted to a top side of the first slider 61. The first sliding chute 8 for the first sliding block 63 to slide along the height direction is arranged on the inner side wall of the standing box 2 where the first driving mechanism 6 is arranged. The first floating block 61 and the ejector rod 62 are located right below the water guide tank 3, and the top end of the ejector rod 62 faces the water guide tank 3.

The second driving mechanism 7 includes a second slider 71, a connecting rod 72, a second slider 73, and a magnet 74. The second slider 73 is fixedly mounted on the side wall of the second floating block 71, and a second chute 9 for sliding the second slider 73 in the height direction is formed in the inner side wall of the standing box 2 where the second driving mechanism 7 is located. A magnet 74 is fixedly mounted to the inner wall of the tip end of the second chute 9, and the magnet 74 is for attracting the second slider 73. One end of the connecting rod 72 is hinged to the top side of the second floating block 71, and the other end of the connecting rod 72 is hinged to the outer bottom wall of the water guide tank 3.

When the two standing boxes 2 are free of oily wastewater, the water guide tank 3 is pushed, and the water guide tank 3 is inclined towards the standing box 2 where the second driving mechanism 7 is located. The water guide tank 3 is then kept inclined toward the stationary box 2 where the second driving mechanism 7 is located by the weight of the second float 71. The oily wastewater is discharged into the water guide tank body 3, and the oily wastewater flows into the standing box 2 where the second driving mechanism 7 is positioned under the influence of the inclination direction of the water guide tank body 3.

The second slider 73 attracts the magnets 74 to lower the inclination of the water guide tank 3 to the stationary box 2 where the second driving mechanism 7 is located when the stationary box 2 where the first driving mechanism 6 is located is not filled.

When the first driving mechanism 6 is full, the first floating block 61 floats upward, and the first slider 63 and the first chute 8 function as guides. The first slider 61 applies an upward pushing force to one end of the water guiding groove 3 through the jack 62, and the second slider 71 applies a downward weight to the other end of the water guiding groove 3, thereby separating the second slider 73 from the magnet 74. The water guide tank 3 is inclined toward the stationary box 2 where the second driving mechanism 7 is located.

When the standing box 2 where the second driving mechanism 7 of the cavity of the water guide tank body 3 is located is inclined, the oily wastewater in the standing box 2 where the first driving mechanism 6 is located is subjected to standing separation, and then oil and water are discharged. The two standing boxes 2 are used alternately, so that the standing separation of the oily wastewater is facilitated. Meanwhile, the water guide tank 3 is automatically changed into the other standing tank 2 after one standing tank 2 is filled with oily wastewater through the first driving mechanism 6 and the second driving mechanism 7, and no additional driving energy is needed, so that the energy-saving effect is achieved.

Referring to fig. 1 and 4, both stationary tanks 2 are provided with a drain mechanism 10 and an oil drain mechanism 11.

The second oil drain pipe 112 is sleeved on the second oil drain pipe 112 in a lifting manner. The limiting ring 113 is screwed on the first oil drain pipe 111, and the limiting ring 113 is located below the second oil drain pipe 112. One end of the first lifting rope 1143 is fixedly connected with the top end of the second oil drain pipe 112, and the other end of the first lifting rope 1143 is fixedly connected with the third floating block 1142. A third float mass 1142 is located inside the other stationary box 2. There are a plurality of first fixed pulleys 1141, and there are two first fixed pulleys 1141 for each first lifting and lowering in the present application. One first fixed pulley 1141 is fixedly mounted to the top side of one stationary box 2, and the other first fixed pulley 1141 is fixedly mounted to the top side of the other stationary box 2. The first hoist rope 1143 is wound around two first fixed pulleys 1141.

Referring to fig. 4 and 6, the drainage mechanism 10 includes a drainage pipe 101, a blocking block 102, a floating plate 104, a guide bar 103, and a second elevating assembly 105, and the second elevating assembly 105 includes a second fixed pulley 1051 and a second hanging rope 1052. The drain pipe 101 is fixedly installed at the bottom side of the stationary box 2, and the drain pipe 101 communicates with the interior of the stationary box 2. The blocking block 102 is used for blocking one end of the drain pipe 101 connected with the standing box 2, and the floating plate 104 is fixedly arranged on one side of the blocking block 102 away from the drain pipe 101. The guide rod 103 is fixedly arranged on the inner bottom wall of the standing box 2, and the floating plate 104 is provided with a through hole 12 for the guide rod 103 to penetrate.

After one of the stationary tanks 2 is filled with the oily wastewater, the first driving mechanism 6 and the second driving mechanism 7 drive the water guiding tank 3 to turn to the other stationary tank 2 to discharge the oily wastewater. In the process that the oily wastewater in the other static tank 2 is gradually increased to be contacted with the third floating block 1142, the oily wastewater in the static tank 2 is already static and layered into oil in the upper layer and water in the lower layer.

The oily wastewater in the other holding tank 2 then continues to increase, thereby causing the third float mass 1142 to move upward. After the third floating block 1142 moves upward, the tension of the third floating block 1142 on the second oil drain pipe 112 by the first hoist rope 1143 is reduced, so that the second oil drain pipe 112 moves downward. The second oil drain pipe 112 is then lower than the water level inside the stationary tank 2, so that the oil flows into the second oil drain pipe 112, and is then discharged from the first oil drain pipe 111. When the second oil drain pipe 112 abuts against the limiting ring 113, the third floating block 1142 continues to move upwards, the second oil drain pipe 112 does not continue to descend, and the oil in the stationary tank 2 is discharged.

After the second oil drain pipe 112 abuts against the limiting ring 113, the second oil drain pipe 112 pulls the blocking block 102 through the second lifting rope 1052, and meanwhile, the blocking block 102 is also subjected to buoyancy of the floating plate 104, so that the blocking block 102 is far away from the drain pipe 101. After the block 102 is far from the drain pipe 101, the floating plate 104 continues to drive the block 102 to move upward. The guide bar 103 cooperates with the through hole 12 to perform a guide function.

After that, the water in the stationary tank 2 is discharged from the drain pipe 101, the water level in the stationary tank 2 gradually decreases, and the floating plate 104 and the block 102 move downward to approach the drain pipe 101. Then, the suction force of the drain water of the drain pipe 101 to the blocking block 102 drives the blocking block 102 to block the drain pipe 101 again, and meanwhile, the blocking block 102 drives the second oil drain pipe 112 to move upwards for a certain distance. Through oil discharging mechanism 11 and drainage mechanism 10 to conveniently stew the oily waste water in the incasement 2 of standing and drain oil and water after the separation, play energy-conserving effect simultaneously.

The capacity of the lower part of the standing box 2 is increased through the expansion box, so that the starting time of the oil discharging mechanism 11 and the water discharging mechanism 10 is prolonged, and the standing separation of oily wastewater is facilitated. The bottom side of expansion tank 13 flushes with the bottom side of standing tank 2, and the top side of expansion tank 13 is gradually reduced from being close to the standing tank 2 side to keeping away from the standing tank 2 side and is the slope setting. When the oily wastewater in the expansion tank 13 is layered, the oil is guided to flow to the standing tank 2 by the inclined top side of the expansion tank 13, so that the oil discharge mechanism 11 can discharge the oil conveniently.

The sealing bag 14 is connected with an exhaust pipe 15, and one end of the exhaust pipe 15 away from the sealing bag 14 is fixedly arranged on the top side of the standing box 2. The sealing bag 14 is used for shielding a gap between the bottom end of the first oil drain pipe 111 and the peripheral side wall of the second oil drain pipe 112, so that oily wastewater is reduced from entering between the first oil drain pipe 111 and the second oil drain pipe 112. The exhaust duct 15 is used to exhaust the air inside the sealing bag 14, thereby reducing the occurrence of the sealing bag 14 obstructing the lifting of the second oil discharge duct 112.
