DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] For example, Figures 1-5As shown, a floating oil pumping device includes an oil pumping groove 1 and an oil outlet pipe 2. The oil pumping groove 1 is installed in a cleaning tank. When the cleaning tank is cleaned, the cleaning liquid overflows into the oil pumping groove 1. Considering the density of the oil stains, generally, the oil stains float on the surface of the cleaning liquid. A layer of floating oil on the surface enters the oil pumping groove 1 first, and is separated first by the overflow. The liquid level in the oil pumping groove 1 rises. One end of the oil outlet pipe 2 is located in the oil pumping groove 1, and the other end of the oil outlet pipe 2 is arranged through the side wall of the oil pumping groove 1. An oil pumping pipe 3 is inserted into the end of the oil outlet pipe 2 in the oil pumping groove 1. An oil pumping port 4 is connected to the upper part of the oil pumping pipe 3. The oil pumping port 4 is trumpet-shaped. The diameter of the end of the oil pumping port 4 connected to the oil pumping pipe 3 is smaller than the diameter of the other end. This structure facilitates the entry of the oil stains. A floating ball 6 is installed on the oil pumping pipe 3. When the liquid level reaches a certain height, the oil pumping pipe 3 rises with the rising of the liquid level and falls with the falling of the liquid level through the buoyancy generated by the floating ball 6. The oil stains on the surface of the liquid level enter through the oil pumping port 4 and are discharged from the oil pumping groove 1. The oil outlet pipe 2 includes a horizontal pipe 7 and a vertical pipe 8. The vertical pipe 8 is located in the oil pumping groove 1. The vertical pipe 8 and the horizontal pipe 7 are connected through an elbow. The lower end of the oil pumping pipe 3 is inserted into the upper end of the vertical pipe 8.

[0022] The end of the oil outlet pipe 2 extending out of the oil pumping groove 1 can be connected to an external mechanism such as an oil pumping pump, etc. This can better pump out the oil stains and send them into an oil-water separator for treatment.

[0023] Two mounting blocks 12 are connected to the outer periphery of the oil pumping pipe 3. The included angle between the two mounting blocks 12 is 180°, and the two mounting blocks 12 are symmetrically arranged. A screw rod 13 is connected to the upper part of the mounting block 12. The screw rod 13 is vertically arranged. The floating ball 6 is installed on the screw rod 13. The symmetric arrangement makes the force on the oil pumping pipe 3 uniform. The floating ball 6 can stably drive the oil pumping pipe 3 to rise, so that the oil pumping pipe 3 does not deviate during the rising and falling process.

[0024] A through hole 14 is formed in the floating ball 6. The screw rod 13 passes through the through hole 14. A butterfly nut 15 is threadedly connected to the part of the screw rod 13 passing through the through hole 14. The position of the butterfly nut 15 on the screw rod 13 is adjusted by rotating the butterfly nut 15. The upper limit position of the floating ball 6 is changed. The distance between the upper end of the oil pumping port 4 and the liquid level is adjusted. The thickness of the oil stain layer on the surface of the liquid is increased or decreased. The distance is controlled to be 5-7 mm. Finally, a reasonable oil-water separation capacity is achieved. The treatment capacity of the oil-water separator is not exceeded. The oil stains in the cleaning tank are not accumulated. The oil stains are pumped out by the overflow method. The loss of the cleaning agent in the liquid is reduced. The cost and labor of adding the cleaning agent are saved. Since most of the oil stains are pumped out, the efficiency of the subsequent oil-water separation treatment of the oil stains is improved. The overall efficiency of the cleaning workpiece is improved.

[0025] As shown in FIG. 1, Figure 4 , Figure 5As shown, the outer periphery of the end of the vertical pipe 8 is connected with a mounting ring 19, the upper part of the mounting ring 19 is connected with a connecting sleeve 9, the lower end of the oil pumping pipe 3 is inserted into the connecting sleeve 9, the end of the connecting sleeve 9 is provided with a sealing element 5, the sealing element 5 comprises a joint sleeve 10, the joint sleeve 10 is provided with a sealing ring 11. The oil pumping pipe 3 moves with the liquid level, the lower end of the oil pumping pipe 3 moves in the connecting sleeve 9, the joint sleeve 10 and the sealing ring 11 are arranged to ensure the sealing between them. The joint sleeve 10 is internally provided with a mounting groove 17, the sealing ring 11 is mounted in the mounting groove 17. The outer periphery of the sealing ring 11 abuts against the side wall of the mounting groove 17, the inner side of the sealing ring 11 is provided with a sealing lip 16, the inner side of the sealing lip 16 abuts against the outer wall of the oil pumping pipe 3. The sealing between the connecting sleeve 9 and the oil pumping pipe 3 is realized through the sealing ring 11 and the sealing lip 16. Meanwhile, the sealing lip 16 does not affect the lifting of the oil pumping pipe 3. The lower part of the joint sleeve 10 is provided with a clamping groove 18, the upper end of the connecting sleeve 9 is inserted into the clamping groove 18.
