[0017] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3The utility model provides a technical solution: an oil recovery device for wastewater treatment, comprising a device housing 1, one end of the device housing 1 is fixedly connected to a water inlet pipe 2, the other end of the device housing 1 is fixedly connected to a water outlet pipe 3, the inner wall of the device housing 1 is fixedly connected to an oil filter 4, the outer wall of the device housing 1 is provided with an oil discharge port 5, the outer wall of the device housing 1 is fixedly connected to a guide plate 6, the outer wall of the device housing 1 is movably connected to a movable screw rod 7 near the lower part of the guide plate 6 and is fixedly connected to a guide rod 8, and the outer walls of the guide rod 8 and the movable screw rod 7 are both movably connected It is connected to a positioning block 9, and the inner wall of the positioning block 9 is movably connected to a collecting box 10. By arranging a device shell 1, a water inlet pipe 2, a water outlet pipe 3, an oil filter 4, an oil discharge port 5, a guide plate 6, a movable screw rod 7, a guide rod 8, a positioning block 9 and a collecting box 10, it is convenient to clamp and position the collecting box 10, so that the collecting box 10 is more stable during collection, and the problem that the collecting box 10 is prone to shaking during collection, which causes the recovered floating oil to leak, improves the stability of collection, meets people's work needs, and is worthy of popularization and use.

[0019] Furthermore, one end of the oil filter net 4 close to the oil discharge port 5 is tilted downward, and the oil filter net 4 and the oil discharge port 5 cooperate with each other, so that the floating oil can be filtered through the oil filter net 4 .

[0020] Furthermore, the guide plate 6 is inclined when viewed from the side, and is distributed in a "concave" shape when viewed from the front, which facilitates the diversion of floating oil when it is discharged.

[0021] Furthermore, the movable screw rod 7 is meshed with the nut on the inner wall of the positioning block 9, and the positioning block 9 is slidably connected with the movable screw rod 7 through the nut. There are two positioning blocks 9 symmetrically distributed at both ends of the movable screw rod 7, and the threads at both ends of the movable screw rod 7 are distributed in opposite directions, which facilitates the movable screw rod 7 to drive the positioning blocks 9 to slide toward or away from each other.

[0022] Furthermore, the positioning block 9 is slidably connected to the guide rod 8 through the through hole of the inner wall, and the guide rod 8 has a smooth surface, which facilitates the guidance of the positioning block 9.

[0023] When in use, first, the movable screw rod 7 is rotated so that the movable screw rod 7 drives the positioning block 9 to slide under the guidance of the guide rod 8, so that the positioning block 9 clamps and positions the collection box 10, thereby preventing the collection box 10 from shaking and causing leakage when the floating oil is discharged. Then, the water inlet pipe 2 is connected to the external sewage, so that the sewage enters the interior of the device housing 1. Since the density of the floating oil is less than the density of the water source, the floating oil floats above the water source, so that the floating oil is filtered by the oil filter net 4 and discharged through the oil discharge port 5, and then falls into the interior of the collection box 10 under the guidance of the guide plate 6 for collection, thereby completing a series of floating oil collection work. The overall structure is simple, the floating oil collection work is effectively realized, and the cost of floating oil collection is reduced.
