Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an oil-liquid separation device for construction wastewater, comprising a base 1, a hollow barrel 3 is installed on the top of the base 1, a driving motor 17 is fixedly connected to the left side of the hollow barrel 3, the output end of the driving motor 17 passes through the hollow barrel 3 and is fixedly connected to the driving bevel gear 15, the inner bottom wall of the hollow barrel 3 is rotatably connected to the driven bevel gear 12, the driving bevel gear 15 is meshed and connected with the driven bevel gear 12, the top of the driven bevel gear 12 is fixedly connected to a connecting rod 13, the top of the connecting rod 13 is fixedly connected to a rotating blade 14, the top of the base 1 is fixedly connected to pillars 7, the top of the pillars 7 is fixedly connected to a top plate 6, and the top of the top plate 6 is provided with an adsorption mechanism 2;

[0030] Specifically, the construction wastewater is injected into a special hollow barrel 3; the hollow barrel 3 is cleverly designed, not only having sufficient capacity to store wastewater, but also having structural strength to withstand rotating centrifugal force; next, by starting the drive motor 17, the active bevel gear 15 starts to rotate; the meshing transmission of the active bevel gear 15 and the driven bevel gear 12 causes the connecting rod 13 and the rotating blade 14 to also start to rotate; this series of mechanical transmission designs ensures that the wastewater rotates efficiently inside the hollow barrel 3; in the process of wastewater rotation, the adsorption structure on the top of the hollow barrel 3 plays a key role; this adsorption structure uses advanced oil-absorbing materials, which can effectively absorb oil in construction wastewater; through the dual effects of rotation and adsorption, the separation speed of oil in wastewater is greatly improved, thereby achieving an efficient separation effect.

[0031] Reference Figure 1 and Figure 3The adsorption mechanism 2 includes a servo motor 201, the bottom of the servo motor 201 is fixedly connected to the top of the top plate 6, the output end of the servo motor 201 passes through the top plate 6 and is fixedly connected to a hollow block 202, the inner side of the hollow block 202 is engaged with a connecting block 203, a T-shaped rod 204 is installed at the bottom of the connecting block 203, and filling plates 205 are installed on the left and right sides of the bottom of the T-shaped rod 204; a hinge 9 is rotatably connected to the middle part of the right side of the hollow block 202, and a rotating plate 10 is fixedly connected to the right side of the hinge 9; buckles 8 are fixedly connected to the front and rear ends of the left side of the rotating plate 10, and slots 11 are provided at the front and rear ends of the right side of the connecting block 203, and the buckles 8 are respectively engaged with the corresponding slots 11;

[0032] Specifically, when the filling plate 205 needs to be installed, the operator can easily take the connecting block 203 and insert it into the hollow block 202; through the carefully designed snap-fit ​​structure, the hollow block 202 and the connecting block 203 can be quickly and firmly connected together; this step not only simplifies the installation process, but also ensures the accuracy of the position of the connecting block 203; next, the operator only needs to flip the rotating plate 10 to rotate the hinge 9; this action aligns the buckle 8 on the rotating plate 10 with the slot 11; then, by pressing the rotating plate 10, the buckle 8 and the slot 11 are quickly and firmly snapped together; this design not only increases the stability of the connecting block 203 and the hollow block 202 after being combined, but also improves the durability of the entire device The filling plate 205 is provided with a plurality of hollow blocks 202, each of which is provided with a plurality of connecting blocks 203. The hollow blocks 202 are ...

[0033] Reference Figure 1 and Figure 2 The right side of the hollow barrel 3 is connected with a drain pipe 4; the two filling plates 205 are symmetrically designed; a valve 5 is installed on the outside of the drain pipe 4; and a sealing ring 16 is installed on the right side of the driving motor 17;

[0034] Specifically, the valve 5 is opened to discharge the treated water through the drain pipe 4 , the separation efficiency is improved by the symmetrically designed filling plate 205 , and the water leakage is prevented by the sealing ring 16 .

[0035] Working principle: construction wastewater is injected into the hollow barrel 3, and the wastewater is stored through the hollow barrel 3. The driving motor 17 is turned on to drive the active bevel gear 15 to rotate. The rotation of the active bevel gear 15 and the meshing transmission of the driven bevel gear 12 drive the connecting rod 13 and the rotating blade 14 to rotate, so that the wastewater rotates in the hollow barrel 3. At this time, the adsorption structure installed on the top of the hollow barrel 3 is used to adsorb the oil in the construction wastewater, which speeds up the separation speed of the oil in the wastewater, thereby improving the separation efficiency, which can meet the use requirements. When the filling plate 205 needs to be installed, the connecting block 203 is taken out and inserted into the hollow block 202, so that the hollow block 202 is engaged with the connecting block 203, and the position of the connecting block 203 is adjusted. The position is fixed, and the rotating plate 10 is flipped to rotate the hinge 9, so that the buckle 8 on the rotating plate 10 is aligned with the slot 11, and the rotating plate 10 is pressed. At the same time, the buckle 8 and the slot 11 are engaged, which further increases the stability of the connection block 203 and the hollow block 202 after being combined. The servo motor 201 is turned on to drive the hollow block 202 to rotate, thereby rotating the T-bar 204 and the filling plate 205. The filling plate 205 can be filled with materials such as activated carbon. The filling plate 205 is used to adsorb and separate the oil in the construction wastewater. When it is necessary to disassemble and replace the filling plate 205, the connecting block 203 can be pulled out from the hollow block 202, thereby achieving the effect of quickly replacing the filling plate 205, thereby avoiding the treatment progress being affected.
