[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The wastewater treated in the sedimentation tank is sometimes mixed with oil, which will float and accumulate on the water surface. The oil floating on the water body is not easy to handle, and some oils are relatively expensive and have extremely high recycling value. In view of the above problems, the present application mainly collects the floating oil in the sedimentation tank through a sedimentation tank floating oil collection device, which can greatly improve the collection efficiency of the floating oil through automatic operation. Among them, the sedimentation tank 100 can be an inclined tube sedimentation tank or a straight tube sedimentation tank, or other types of sedimentation tanks. The user can install the device in the sedimentation tank according to the actual situation, and there is no limitation here.

[0042] Please refer to Figures 1 to 3In the embodiment of the present invention, a floating oil collection device 1 for a sedimentation tank is provided. The floating oil collection device 1 for a sedimentation tank mainly comprises: a hollow oil collecting tank 2 arranged in a sedimentation tank 100, a collecting tube 3 and a height adjustment mechanism 4.

[0043] The oil collecting tank 2 includes: a top with an oil inlet 21 and a bottom with an oil outlet 22. Specifically, the oil collecting tank 2 can be directly set in the sedimentation tank 100 when in use, so that the oil collecting tank 2 can be located below the water surface of the sedimentation tank 100, so that the floating oil can automatically slide to the bottom with the oil outlet 22 along the weight. Of course, as another variant of the setting method of the oil collecting tank 2, the main body of the oil collecting tank 2 can also be set outside the sedimentation tank 100, and the oil inlet 21 is set in the sediment. The user can adjust the installation position between the oil collecting tank 2 and the sedimentation tank 100 according to the installation environment, and there is no restriction here. When in use, the floating oil collected by the collection tube 3 flows into the oil collecting tank 2 and is collected to the oil outlet 22 under the action of gravity and is quickly discharged, thereby avoiding the agglomeration of the floating oil in the oil collecting tank 2; of course, the floating oil can also be temporarily stored in the oil collecting tank 2.

[0044] The collecting tube 3 includes: a first end 31 provided with an oil production port and a second end 32 opposite to the first end 31. The collecting tube 3 is movably connected to the oil inlet 21. The first end 31 is arranged above the oil inlet 21, and the second end 32 is connected to the oil collecting tank 2 through the oil inlet 21. By adjusting the setting height of the collecting tube 3 in the sedimentation tank 100, the floating oil in the sedimentation tank 100 can overflow into the collecting tube 3 along the oil production port, and then the floating oil flows into the oil collecting tank 2. The collecting tube 3 has a smaller size than the oil collecting tank 2, which is convenient for adjustment and use.

[0045] The height adjustment mechanism 4 is connected to the collection tube 3, and the setting position of the oil production port in the sedimentation tank 100 can be adjusted by the height adjustment mechanism 4. Specifically, the setting position can be a vertical height position or an inclined height position, and the user can adjust it according to the needs, which is not limited here.

[0046] During use, the height adjustment mechanism 4 can be used to control the collection tube 3 to move up and down in the sedimentation tank 100, so that the water flow carries the floating oil and intermittently overflows into the oil collecting tank 2 along the oil production port of the collection tube 3. The intermittent oil production method can stir the water body, promote the uniform distribution of the floating oil, and enable the floating oil to flow to the collection tube 3 driven by the water flow, thereby facilitating the collection of the floating oil at the oil production port, thereby increasing the oil collection efficiency; or, the collection tube 3 can be fixed to the bottom of the floating oil layer of the sedimentation tank 100 through the height adjustment mechanism 4, so that the floating oil continues to overflow into the oil collecting tank 2 along the oil production port of the collection tube 3; of course, the user can also combine the height adjustment mechanism 4 with a control mechanism such as a displacement sensor suitable for the height adjustment mechanism 4, so that the height adjustment mechanism 4 can automatically adjust the setting height or movement mode of the collection tube 3 in the sedimentation tank 100 according to the liquid level in the sedimentation tank 100.

[0047] In general, the floating oil collection device 1 provided in the present application can realize the oil collection process and the oil discharge process simultaneously when used in the sedimentation tank 100. The present application can drive the collection tube 3 to automatically operate in the sedimentation tank 100 through the height adjustment mechanism 4, thereby efficiently realizing the recovery of floating oil and reducing the labor intensity.

[0048] In this application specification, the present invention will be described in detail with reference to specific implementation methods and drawings.

[0049] For details, please refer to Figures 1 to 3 The floating oil collection device 1 of the sedimentation tank may include: an oil collecting tank 2; a collecting tube 3; a height adjustment mechanism 4; a sliding seal 5; a mounting frame 6; and an adjustment frame 7.

[0050] In this embodiment, the collecting barrel 3 may include a first barrel section 33 and a second barrel section 34 connected to the first barrel section 33, the first end 31 is the top end of the first barrel section 33, the second end 32 is the bottom end of the second barrel section 34, and the second barrel section 34 is at least partially movably inserted into the oil inlet 21.

[0051] Specifically, the first barrel section 33 is flared from one end connected to the second barrel section 34 toward the first end 31. The flared first end 31 is conducive to increasing the oil recovery efficiency of the collection barrel 3. The flared first barrel section 33 can also play a blocking role to prevent the collection barrel 3 from sliding into the oil collecting tank 2. Of course, a baffle 35 can also be connected between the first barrel section 33 and the second barrel section 34 to prevent the collection barrel 3 from sliding into the oil collecting tank 2. The baffle 35 can also avoid collision between the oil inlet 21 and the collection barrel 3.

[0052] In this embodiment, in order to facilitate the movable installation of the collection tube 3 on the oil collecting tank 2, the oil collecting tank 2 can be set to the following shape: the top includes an upper limiting sleeve 23, the bottom includes a lower conical tank body 25, and a middle tank body 24 is provided between the upper limiting sleeve 23 and the lower conical tank body 25. Among them, the oil discharge port 22 is arranged at the bottom of the lower conical tank body 25, and the oil discharge port 22 and the oil inlet 21 are arranged at the same height direction. By arranging the oil discharge port 22 and the oil inlet 21 at the same height direction, the floating oil and sewage entering the oil collecting tank 2 can quickly fall to the oil discharge port 22, especially when the oil collection process and the oil discharge process are carried out simultaneously, so that the oil discharge efficiency is greatly improved.

[0053] Specifically, the middle tank body 24 can be set to be cylindrical. Of course, the oil collecting tank 2 can also be set to other shapes, and the user can reasonably set it according to the needs, which is not limited here.

[0054] Furthermore, the upper limiting sleeve 23 is provided with a hollow cylinder cavity connected to the middle tank body 24, the hollow cylinder cavity forms the oil inlet 21, the second cylinder section 34 is at least partially movably inserted in the hollow cylinder cavity, and the oil discharge port 22 is arranged on the lower conical tank body 25. The at least partially means that during the movement of the second cylinder section 34, the second cylinder section 34 can completely enter the hollow cylinder cavity; or the bottom of the second cylinder section 34 is located in the hollow cylinder cavity, and the rest can extend out of the hollow cylinder cavity. By providing the lower conical tank body 25, it is convenient to gather the floating oil in the oil collecting tank 2 to the oil discharge port 22, so that the floating oil in the oil collecting tank 2 can be discharged more cleanly, and the floating oil can be prevented from agglomerating in the oil collecting tank 2.

[0055] Since the oil collecting tank 2 is arranged in the sedimentation tank 100, in order to prevent sewage from entering the oil collecting tank 2 along the gap between the second barrel section 34 and the hollow barrel cavity, a sliding seal 5 may be provided between the second barrel section 34 and the upper limiting sleeve 23. Specifically, the sliding seal 5 may be a sealing ring, and one or more sealing rings may be provided between the second barrel section 34 and the hollow barrel cavity, which is not limited here. Of course, the user may also use other sealing structures having the same function as the sliding seal 5, which is not limited here.

[0056] In this embodiment, the collection tube 3 needs to be adjusted by the height adjustment mechanism 4. In order to increase the adjustment accuracy, the height adjustment mechanism 4 can be fixedly installed on the oil collecting tank 2. Specifically, a mounting frame 6 is provided on the oil collecting tank 2, and the mounting frame 6 includes at least one first mounting member 61 and at least one second mounting member 62. The first mounting member 61 is arranged above the oil collecting tank 2, and the height adjustment mechanism 4 is connected to the first mounting member 61. The second mounting member 62 is respectively connected to the oil collecting tank 2 and the first mounting member 61 for support. Specifically, the first mounting member 61 and the second mounting member 62 can adopt a plate-shaped structure or a rod-shaped structure, and a second mounting member 62 can be arranged at each end of the first mounting member 61, so that the stability of the mounting frame 6 is better. The mounting frame 6 allows the height adjustment mechanism 4 and the oil collecting tank 2 to have a fixed relative position, which is convenient for the height adjustment mechanism 4 to adjust the collection tube 3 and can improve the adjustment accuracy.

[0057] The height adjustment mechanism 4 includes a hydraulic oil cylinder 41 and a telescopic rod 42 mounted on the hydraulic oil cylinder 41, and the telescopic rod 42 is connected to the collection tube 3. In this embodiment, the hydraulic oil cylinder 41 and the matching oil cylinder control system can be used in combination for the convenience of users. Of course, users can also use the oil cylinder control system in conjunction with a displacement sensor to obtain an automatic control effect. Users can reasonably adapt the height adjustment mechanism 4 to other control systems or sensor systems to obtain better use effects, which is not limited here.

[0058] Furthermore, a fixing piece 421 is provided on the telescopic rod 42, and the telescopic rod 42 is connected to the collection tube 3 through the fixing piece 421, and the axis of the telescopic rod 42 is colinear with the axis of the collection tube 3. The axes of the telescopic rod 42 and the collection tube 3 can be arranged along the gravity direction, so that when the collection tube 3 is immersed in water, the floating oil can evenly enter the collection tube 3 along the oil production port, so that the collection effect of the collection tube 3 is better. Specifically, the fixing piece 421 can be made of channel steel.

[0059] The liquid level in the sedimentation tank 100 changes frequently, and the adjustment range of the collecting tube 3 is limited. In order to make the sedimentation tank floating oil collection device 1 more adaptable, in this embodiment, an adjustment frame 7 is provided between the oil collecting tank 2 and the sedimentation tank 100, and the adjustment frame 7 may include:

[0060] Support member 71, both ends of the support member 71 are provided with connecting parts 711, and the connecting parts 711 are connected to the tank body of the sedimentation tank 100. During installation, the connecting part 711 is fixed to the two tank walls of the sedimentation tank 100 through a detachable structure or the connecting part 711 is detachably fixed to the top surface of the sedimentation tank 100. Specifically, one implementation of the connecting part 711 is: the connecting part 711 can use a plate structure, and the plate structure can be fixed to the sedimentation tank 100 by bolts. Of course, the user can reasonably choose other installation methods according to actual conditions, and there is no limitation here.

[0061] Furthermore, a lifting and adjusting member 72 is arranged on the support member 71, and the lifting and adjusting member 72 is arranged above the oil collecting tank 2. The lifting and adjusting member 72 may include: a fixed end 721 and a lifting and adjusting end 722 opposite to the fixed end 721, the fixed end 721 is connected to the oil collecting tank 2 or the mounting frame 6, and the lifting and adjusting end 722 is adjustably connected to the support member 71, and the setting height of the oil collecting tank 2 in the sedimentation tank 100 can be adjusted by the lifting and adjusting member 72.

[0062] Specifically, the lifting adjustment end 722 is provided with a threaded section, the support member 71 is provided with an adjustment nut 73 matched with the threaded section, and the lifting adjustment end 722 is threadedly connected to the adjustment nut 73. The lifting adjustment member 72 can be made of a screw. When in use, the lifting adjustment member 72 can be rotated, and the upper and lower positions of the oil collecting tank 2 in the sedimentation tank 100 can be adjusted by the lifting adjustment member 72, so that the device can be applied to different liquid level heights, thereby obtaining a better use effect.

[0063] During use, floating oil is easy to agglomerate in the oil collecting tank 2, and quickly discharging the floating oil can avoid the agglomeration phenomenon. In this embodiment, the oil discharge port 22 is connected to an oil delivery pipeline 8, and an oil suction pump 81 is installed on the oil delivery pipeline 8. When the floating oil enters the oil collecting tank 2, the floating oil and sewage in the oil collecting tank 2 can be quickly pumped out through the oil delivery pipeline 8 to prevent the floating oil from agglomerating in the oil collecting tank 2.

[0064] When the floating oil collection device 1 for the sedimentation tank described in the present invention is used, the collection tube 3 is used to collect the floating oil in the sedimentation tank 100, and the collected floating oil flows into the oil collecting tank 2 and is discharged along the oil discharge port 22. During use, the collection tube 3 can be controlled to move up and down in the sedimentation tank 100 by the height adjustment mechanism 4, so that the water flow entrains the floating oil and intermittently overflows into the oil collecting tank 2 along the oil production port of the collection tube 3. The intermittent oil production method can stir the water body, promote the uniform distribution of the floating oil, and enable the floating oil to flow to the collection tube 3 driven by the water flow, so as to facilitate the collection of the floating oil at the oil production port. Of course, the collection tube 3 can also be fixed below the floating oil layer of the sedimentation tank 100 by the height adjustment mechanism 4, so that the floating oil continues to overflow into the oil collecting tank 2 along the oil production port of the collection tube 3.

[0065] The beneficial effects of the floating oil collection device 1 for the sedimentation tank of the present invention are that the collection device of the present application can realize the oil collection process and the oil discharge process at the same time through the cooperation of the oil collection tank 2 and the collection tube 3, thereby avoiding the agglomeration of the floating oil in the oil collection tank 2. The height adjustment mechanism 4 can drive the collection tube 3 to automatically operate in the sedimentation tank 100, efficiently realize the recovery of floating oil, reduce the labor intensity, and have the advantages of reliable operation and high oil collection efficiency.

[0066] The present invention further discloses a sedimentation tank 100 , and the sedimentation tank 100 includes the sedimentation tank floating oil collection device 1 described in the above embodiment. Specifically, the sedimentation tank floating oil collection device 1 can be arranged in the sedimentation tank 100 .

[0067] The sedimentation tank 100 described in the present invention can efficiently collect the floating oil in the sedimentation tank 100 through the sedimentation tank floating oil collection device 1. After the floating oil is collected, it can purify the water quality and enhance the sewage treatment effect of the sedimentation tank 100.
