Detailed Embodiments

[0015] The following further describes the specific embodiments of the present utility model with reference to the drawings.

[0016] Such as Figures 1-3As shown in the figure, a wastewater treatment device includes a storage water tank 1. An oil storage tank 2 is arranged on the storage water tank 1. Both the storage water tank 1 and the upper end of the oil storage tank 2 are open. An installation frame 3 is arranged at the upper end of the oil storage tank 2. A support frame 4 is arranged on the upper end surface of the oil storage tank 2. A fixed rod 5 and a lead screw 6 are arranged on the support frame 4. One end of the installation frame 3 is slidably connected to the fixed rod 5, and the other end of the installation frame 3 is threadedly connected to the lead screw 6. A first motor 7 for driving the rotation of the lead screw 6 is arranged on one side of the support frame 4. A driving wheel 8 is arranged on the installation frame 3. A second motor 9 for driving the rotation of the driving wheel 8 is arranged on one side of the installation frame 3. A pressing wheel 10 is arranged above the driving wheel 8 on the installation frame 3. Support rods 11 are respectively arranged on both sides of the oil storage tank 2 inside the storage water tank 1. Sleeves 12 are slidably connected to the support rods 11. An endless belt 13 is further included. The endless belt 13 is used to connect the two sleeves 12 and the driving wheel 8. An oil-loving and water-repellent coating material is arranged on the outer surface of the endless belt 13. The installation frame 3 and the sleeve 12 are connected by a cover plate 14.

[0017] When treating wastewater, first, the wastewater is conveyed into the storage water tank 1. The oil-loving and water-repellent coating material on the outer surface of the endless belt 13 between the two sleeves 12 contacts the liquid level of the wastewater, so that the oil on the upper layer of the wastewater can be adsorbed on the coating material on the outer surface of the endless belt 13. The outer surface of the driving wheel 8 has tooth grooves, and the inner surface of the endless belt 13 also has corresponding tooth grooves. When the second motor 9 is started, the second motor 9 drives the driving wheel 8 to rotate, and the driving wheel 8 can drive the endless belt 13 to move. During the movement of the endless belt 13, the coating material entering between the pressing wheel 10 and the driving wheel 8 is squeezed by the pressing wheel 10 and the driving wheel 8. Under the action of extrusion, the oil adsorbed by the coating material flows into the oil storage tank 2. At the same time, the first motor 7 is started, and the first motor 7 controls the rotation of the lead screw 6. Through the cooperation of the lead screw 6 and the fixed rod 5, the installation frame 3 can move linearly along the lead screw 6. Since the installation frame 3 and the sleeve 12 are connected by the cover plate 14, when the installation frame 3 moves linearly along the lead screw 6, the sleeve 12 is driven to move along the support rod 11 through the cover plate 14, so as to change the position of the endless belt 13, so that the coating material on the surface of the endless belt 13 can move on the liquid level of the wastewater, and the oil on the liquid level of the wastewater can be effectively absorbed and squeezed into the oil storage tank 2.

[0018] The coating material can be materials such as polypropylene fiber and alkyl vinyl polymer fiber.

[0019] Further, a liquid level control box 15 is arranged on one side of the storage water tank 1. The liquid level control box 15 is connected to the storage water tank 1 in a through manner. When discharging wastewater into the storage water tank 1, when the wastewater starts to flow into the liquid level control box 15, stop discharging wastewater into the storage water tank 1. At this time, the coating material on the endless belt 13 between the two sleeves 12 can just adsorb the oil on the liquid surface, so as to improve the efficiency of the coating material in adsorbing oil.

[0020] Further, it further includes a cage 16 for installing the pressure wheel 10. The cage 16 is located inside the mounting frame 3 and is slidably connected to the mounting frame 3. Guide rods 17 are symmetrically arranged on the upper end face of the cage 16. The guide rods 17 are slidably connected to the mounting frame 3. A bolt 18 is threadedly connected to the upper end of the mounting frame 3. The lower end of the bolt 18 is rotatably connected to the upper end of the cage 16. By rotating the bolt 18, the distance between the pressure wheel 10 and the driving wheel 8 can be controlled, and thus the extrusion force applied by the pressure wheel 10 and the driving wheel 8 to the covering material on the endless belt 13 can be controlled, which is convenient for effectively extruding the oil stains adsorbed by the covering material.

[0021] Further, a bottom plate 19 is arranged on one side of the water storage tank 1. An oil receiving barrel 20 is arranged on the bottom plate 19. One end of the oil storage tank 2 is open. The open end of the oil storage tank 2 is located directly above the oil receiving barrel 20. The inner bottom surface of the oil storage tank 2 is inclined. The oil stains entering the oil storage tank 2 can flow along the inner bottom surface of the oil storage tank 2 into the oil receiving barrel 20, and the receiving and transferring of the oil stains are realized through the oil receiving barrel 20.

[0022] Further, a valve 21 is arranged on the water storage tank 1. Through the valve 21, waste water can be conveyed into the water storage tank 1, and the waste water that has completed the adsorption of oil stains can also be discharged from the water storage tank 1.

[0023] When the device treats waste water, it can control the movement of the endless belt 13, so that the covering material can cover the liquid surface of the waste water at a relatively fast speed, thereby quickly separating the oil stains on the liquid surface of the waste water, effectively improving the extraction and separation efficiency of the oil stains, and having a good use effect.
