Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to an oil-water separation rotating bracket. Background Art

[0002] With the development of modern industry, large quantities of wastewater are generated daily. Much of this oily wastewater is discharged directly into municipal networks without any treatment, polluting rivers and groundwater. Grease in wastewater can adhere to and accumulate on the walls of drainage pipes, leading to blockages and corrosion, ultimately paralyzing urban drainage networks.

[0003] Oil-water separation involves separating oil from oily wastewater and performing specialized treatment, which facilitates resource reuse and protects the environment. Traditional oil-water separation technologies suffer from low separation efficiency and complex operations, making them difficult to meet the demands of modern industry for efficient and environmentally friendly treatment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a rotary bracket which can improve the continuity and automation of oil-water separation.

The axis of the oil collecting rod is parallel to the axis of the collection pipe. The oil collecting rods rotate around the outer wall of the collection pipe and can extend into the gap.

[0007] The beneficial effects of the utility model are as follows: the rotating frame drives the oil collecting rod to sink into the water to absorb the floating oil, and then moves to the extrusion plate, and the floating oil is squeezed by the outer wall of the collection pipe and the extrusion plate, and flows into the collection tank.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the oil collecting rod includes a rotating rod and a flexible oil suction sleeve. One end of the rotating rod is rotatably mounted on the rotating frame, and the flexible oil suction sleeve is sleeved on the rotating rod.

[0010] The beneficial effects of adopting the above further solution are: the rotating rod ensures the strength of the oil collecting rod and is not easy to bend; the flexible oil suction sleeve absorbs oil and is detachable for easy replacement.

[0011] Furthermore, an oleophilic and hydrophobic layer is provided on the surface of the flexible oil-absorbing sleeve.

[0012] The beneficial effects of adopting the above further solution are: accurate adsorption of floating oil and improved oil-water separation efficiency.

[0013] Furthermore, a first gear ring is fixedly connected to the outer peripheral wall of the collecting tube, and a first gear is fixedly connected to each of the rotating rods, and the first gear is meshed with the first gear ring.

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] Example 1

[0035] like Figures 1 to 4 As shown, an oil-water separation rotating bracket includes a collecting pipe 1 mounted on the water surface, the outer peripheral wall of the collecting pipe 1 on one side of which is submerged in the water, and a plurality of collecting grooves 2 are formed on the outer peripheral wall of the collecting pipe 1 away from the water surface. An extrusion plate 3 is provided above the collecting grooves 2, and a gap is provided between the extrusion plate 3 and the outer wall of the collecting pipe 1;

[0036] A rotating frame 4 is rotatably mounted on the outer peripheral wall of the collecting pipe 1. A number of oil collecting rods for absorbing floating oil are evenly arranged around the axis of the rotating frame 4 facing the collecting tank 2. The axis of the oil collecting rod is parallel to the axis of the collecting pipe 1. The oil collecting rod rotates around the outer wall of the collecting pipe 1 and can extend into the gap.

[0037] The beneficial effects of this embodiment are as follows: the rotating frame 4 drives the oil collecting rod to sink into the water to absorb the floating oil, and then moves to the extrusion plate 3. After being squeezed by the outer peripheral wall of the collection pipe 1 and the extrusion plate 3, the floating oil flows into the collection tank 2. The structure is simple, stable and reliable, and the continuity and automation of the oil-water separation process are achieved.

[0038] Specifically, in this embodiment, the collecting pipe 1 can be placed horizontally on the water surface, or can be erected on the water surface at an angle, with its axis forming a certain angle with the water surface, so that the oil floats on the water surface;

[0039] The outer peripheral wall of the oil collecting rod is made of flexible oil-absorbing material. When the rotating frame 4 rotates, the oil collecting rod is driven to move. When the oil collecting rod rotates to the bottom of the collection pipe 1, it sinks into the water and absorbs a large amount of floating oil. Then it rotates out of the water and moves to between the outer peripheral wall of the collection pipe 1 and the extrusion plate 3. The outer diameter of the oil collecting rod is larger than the gap distance. The extrusion plate 3 squeezes out the floating oil absorbed by the oil collecting rod. Under the action of gravity, the squeezed floating oil passes through the collection tank 2 and flows into the collection pipe 1 to complete the oil-water separation.

[0040] As a parallel technical solution of this embodiment, the oil collecting rod can also be replaced by a flexible oil absorption block. The rotating frame 4 rotates and is located between the outer peripheral wall of the collection pipe 1 and the extrusion plate 3. The oil absorption block is fixed on the outer peripheral wall of the rotating frame 4. When the oil absorption block rotates to the bottom of the collection pipe 1, it absorbs oil. When the oil absorption block rotates to the gap between the collection pipe 1 and the extrusion plate 3, the adsorbed floating oil is squeezed out.

[0041] Example 2

[0042] like Figure 1 and Figure 4 As shown, preferably, on the basis of Example 1, the oil collecting rod includes a rotating rod 5 and a flexible oil suction sleeve 6, one end of the rotating rod 5 is rotatably mounted on the rotating frame 4, and the flexible oil suction sleeve 6 is sleeved on the rotating rod 5.

[0043] The beneficial effects of adopting the preferred solution in the above embodiment are: the rotating rod 5 ensures the strength of the oil collecting rod and is not easy to bend; the flexible oil suction sleeve 6 absorbs oil and is detachable for easy replacement.

[0044] Specifically, the flexible oil-absorbing sleeve 6 can be removed and replaced after long-term use to ensure the best oil-absorbing effect. The flexible oil-absorbing sleeve 6 is made of oil-absorbing cotton or polyurethane fiber or nano-porous material.

[0045] Example 3

[0046] like Figure 1 and Figure 4 As shown, preferably, on the basis of embodiment 1-2, the surface of the flexible oil-absorbing sleeve 6 is provided with an oleophilic and hydrophobic layer.

[0050] The beneficial effect of adopting the preferred solution in the above embodiment is that when the rotating frame 4 rotates, the rotating rod 5 rotates at the same time, allowing the flexible oil absorption sleeve 6 to absorb more floating oil and fully utilize the effective oil absorption area of the flexible oil absorption sleeve 6.

[0051] Specifically, in this embodiment, when the flexible oil absorption sleeve 6 rotates to between the outer peripheral wall of the collection pipe 1 and the extrusion plate 3, the rotating rod 5 keeps rotating, which can also ensure that the floating oil adsorbed at every location on the outer peripheral wall of the flexible oil absorption sleeve 6 can be fully squeezed out, thereby improving the oil discharge efficiency.

[0052] Example 5

[0053] like Figure 1 and Figure 4 As shown, preferably, on the basis of embodiments 1-4, a retaining ring 9 is fixedly mounted on one end of the rotating rod 5 away from the rotating frame 4.

[0054] The beneficial effect of adopting the preferred solution in the above embodiment is to prevent the flexible oil absorption sleeve 6 from sliding out of the rotating rod 5 during rotation.

[0055] Specifically, the retaining ring 9 is also convenient for disassembling and replacing the flexible oil suction sleeve 6 .

[0056] As a parallel technical solution of this embodiment, the retaining ring 9 can also be replaced by a pin, which is inserted into the outer peripheral wall of the end of the rotating rod 5. The axis of the pin is perpendicular to the axis of the rotating rod 5 to prevent the flexible oil suction sleeve 6 from slipping.

[0057] Example 6

[0058] like Figure 1 and Figure 4 As shown, preferably, on the basis of Examples 1-5, a second ring gear 10 is fixedly connected to the rotating frame 4, a rotating power source 11 is fixedly installed on the collecting pipe 1, and a second gear 12 is provided on the output shaft of the rotating power source 11, and the second gear 12 is engaged with the second ring gear 10.

[0060] Specifically, in this embodiment, the angle and speed are precisely controlled by a servo motor, the response speed is fast, and an automated power source is used to reduce labor intensity and improve work efficiency;

[0061] When the rotating frame 4 rotates, the rotating rod 5 rotates synchronously, which has good synchronization and can also save power source.

[0062] Example 7

[0063] like Figure 1 and Figure 2 As shown, preferably, on the basis of Examples 1-6, the extrusion plate 3 is an arc-shaped plate and is coaxial with the collecting pipe 1, and a guide plate 13 is provided at the end of the extrusion plate 3 facing the water surface, and one side of the guide plate 13 is fixedly connected to the end of the extrusion plate 3 facing the water surface, and the other side of the guide plate 13 gradually extends in a direction away from the outer wall of the collecting pipe 1.

[0064] The beneficial effect of adopting the preferred solution in the above embodiment is that the guide plate 13 facilitates the oil collecting rod to better enter the gap when rotating.

[0065] Specifically, in this embodiment, the guide plate 13 is an arc-shaped plate, and its arc direction is opposite to that of the extrusion plate 3. The guide plate 13 increases the gap width and guides the oil collecting rod to gradually enter the gap. Guide plates 13 are provided at both ends of the extrusion plate 3 facing the water surface. The rotating frame 4 can be used normally regardless of whether it rotates clockwise or counterclockwise.

[0066] As a parallel technical solution of this embodiment, the guide plate 13 can also be an inclined plate, as long as it can increase the width of the gap into which the oil collecting rod enters.
