Technical Field

[0001] The invention relates to the technical field of oil removal, in particular to a self-balancing floating ball device. Background Art

[0002] In the industrial processing, it is necessary to extract and separate the floating oil floating on the liquid. The common design at present is to set the inlet of the oil extraction pipeline at the boundary between the oil layer and the cutting fluid layer through a float, and the other end of the oil extraction pipeline is connected to an oil extraction pump to extract and separate the floating oil. In this process, due to the continuous flow and expansion of the liquid and the floating oil and other factors, the balanced float is prone to imbalance. In order to deal with the up and down angle difference of the float caused by the buoyancy of the float, it is usually designed to manually adjust the float up and down. For the left and right angle difference caused by the float itself being affected by the connecting pipe, it is usually designed to manually adjust its left and right directions according to the bending degree of the connecting pipe itself to achieve balance on the water surface, so as to maximize its function.

[0003] However, this adjustment method is time-consuming and labor-intensive, has low efficiency, and may cause the oil pump to be dry for too long, resulting in equipment damage. Summary of the invention

[0014] In one embodiment, the connecting bracket extends vertically downward from the outer edge of the central support plate away from the top surface of the connecting bracket, a vertical through hole in the vertical direction is opened on the connecting bracket, a detachable component is arranged on the float, and the detachable component includes a first fastener fixed on the float, and a second fastener passing through the vertical through hole and detachably connected to the first fastener.

[0015] In one embodiment, the float support further comprises three evenly distributed counterweight plates located on the central support plate, and the counterweight plates are used for installing counterweight blocks.

[0016] In one embodiment, the counterweight plate is tilted upward away from the central support plate and forms a first angle with the central support plate, wherein the first angle is 5°-20°.

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0029] The words expressing position and direction described in the present invention are all explained by taking the accompanying drawings as examples, but they can be changed as needed, and all changes are included in the protection scope of the present invention.

[0030] like Figures 1 to 5 As shown, the self-balancing float device of this embodiment includes a float bracket 1, a float group, a suction end interface 3 and an oil suction transfer tube 4. The self-balancing float device can realize the rotational connection between the suction end interface 3 connected with the connecting pipe and the oil suction transfer tube 4, so that the float group can swing by itself according to the horizontal plane where the float group is located to correct the left and right angle difference, so that the float reaches the best condition.

[0031] Specifically, the float bracket 1 is provided with an oil suction port 11, which can be used to suck the floating oil above the cutting fluid. The float bracket 1 is connected to the float group, and the float group is preferably connected to the outer periphery of the float bracket 1. The float group includes a plurality of floats 2. The float group of this embodiment includes three floats 2. The floats 2 in the float group are preferably stainless steel floats 2. One end of the oil suction transfer pipe 4 is connected to the oil suction port 11, and the upper end of the oil suction transfer pipe 4 of this embodiment is connected to the oil suction port 11. Figure 5 As shown, the float bracket 1 also includes a central support plate 12 located on the top surface of the float bracket 1 , and the oil suction port 11 is located at the center of the central support plate 12 , so that the floating oil flows into the oil suction transfer pipe 4 through the oil suction port 11 .

[0032] The oil suction transfer tube 4 is preferably a 90° bent joint, and a transfer interface 41 is provided at the other end of the oil suction transfer tube 4. The lower end of the oil suction transfer tube 4 of this embodiment is provided with a transfer interface 41, and the transfer interface 41 is rotatably and sealedly connected to the suction end interface 3. The suction end interface 3 is used to connect a connecting pipe, and the connecting pipe is, for example, a leather hose. The suction end interface 3 is preferably a pagoda interface, and the leather hose is tightly sleeved on the outer peripheral surface of the suction end interface 3.

[0033] In this embodiment, if Figure 4 As shown, a rotary bearing 5 is provided between the suction end interface 3 and the transfer interface 41, the rotary bearing 5 is accommodated in the transfer interface 41, and one end of the suction end interface 3 is connected to the rotary bearing 5 and sealed with the transfer interface 41. As an alternative, the rotary bearing 5 can also be sealed and accommodated in one end of the suction end interface 3, and the transfer interface 41 is connected to the rotary bearing 5 and sealed with one end of the suction end interface 3. Both of the above methods can realize the rotatable sealed connection between the transfer interface 41 and the suction end interface 3.

[0034] In an alternative embodiment, the suction port interface 3 is sealed and connected to the transfer port 41 by using a ball-and-socket joint structure, so that the suction port interface 3 can achieve a wider range of rotation at the transfer port 41 .

[0035] When in use, the float 2 is placed on the horizontal plane of the liquid surface, and the other end of the suction end interface 3 away from the transfer interface 41 is pressed into the connecting pipe. When the weight of the connecting pipe itself and the weight of the water flowing in causes the whole to be unbalanced, since the transfer interface 41 and the suction end interface 3 are rotatably sealed and connected, the connecting pipe and the transfer interface 41 can be rotatably connected, so that the float group can swing by itself according to the horizontal plane to correct the angle difference in the left and right directions, so that the float 2 reaches the best condition.

[0036] like Figure 5 As shown, in the self-balancing float device, the float bracket 1 also includes three connecting brackets 13 evenly distributed along the outer circumference of the float bracket 1, each connecting bracket 13 is connected to a float 2, and the float 2 can be installed on the connecting bracket 13 by screwing, and the connecting bracket 13 facilitates the installation of the float 2.

[0037] In this embodiment, the connecting bracket 13 extends vertically downward from the edge of the central support plate 12, facing away from the top surface of the connecting bracket 13. A vertical through hole 131 in the vertical direction is provided on the connecting bracket 13. A detachable component is provided on the float 2. The detachable component includes a first fastener fixed on the float 2, and a second fastener passing through the vertical through hole 131 and detachably connected to the first fastener. The vertical length of the vertical through hole 131 is greater than the longitudinal section height of the connection between the second fastener and the vertical through hole 131, so as to achieve the up and down adjustment of the float 2 on the connecting bracket 13. Specifically, the first fastener is, for example, a nut 21, and the second fastener is, for example, a bolt 22. The vertical length of the vertical through hole 131 is greater than the diameter of the screw on the bolt 22, so as to achieve the up and down adjustment of the float 2 on the connecting bracket 13.

[0038] like Figure 5 As shown, the float bracket 1 also includes three evenly distributed counterweight plates 14 located on the central support plate 12. In this embodiment, the three counterweight plates 14 are evenly distributed on the central support plate 12, and the counterweight plates 14 are used to install counterweight blocks.

[0039] In this embodiment, a counterweight screw hole 141 is provided on the counterweight plate 14. Figure 4 As shown, a counterweight screw 142 is installed in the counterweight screw hole 141, and a counterweight block can be installed on the counterweight screw 142, so that the up and down buoyancy of the float 2 can be adjusted by installing counterweight blocks of different weights.

[0040] In this embodiment, if Figure 4 and Figure 5 As shown, the counterweight plate 14 is tilted upward with its back to the center support plate 12 and forms a first angle with the center support plate 12. The first angle is 5°-20°, and is 10° in this embodiment. The upward tilted counterweight plate 14 is beneficial for avoiding interference with the float 2 when installing the counterweight block.

[0041] like Figures 1 to 5 As shown, in the self-balancing float device, one end of the oil suction transfer tube 4 is rotatably sealed and connected to the float bracket 1, that is, the upper end of the oil suction transfer tube 4 is rotatably sealed and connected to the float bracket 1, so that the oil suction transfer tube 4 can also rotate, thereby achieving a larger angle of free rotation. Specifically, the upper end of the oil suction transfer tube 4 and the float bracket 1 can be rotatably sealed and connected through a rotating bearing 5, and the rotating bearing 5 can be accommodated in the float bracket 1, and the rotating bearing 5 can also be accommodated in the upper end of the oil suction transfer tube 4. The upper end of the oil suction transfer tube 4 is sealed and matched with the float bracket 1. The rotatable sealing connection between the upper end of the oil suction transfer tube 4 and the float bracket 1 can be the same as the rotatable sealing connection between the suction end interface 3 and the transfer interface 41, which will not be repeated here.

[0042] In summary, in the self-balancing float device of the present invention, when the float is placed on a horizontal plane and the other end of the suction end interface away from the adapter is pressed into the connecting pipe, the adapter of the oil suction adapter tube and the suction end interface are rotatably sealed and connected, so the connecting pipe and the adapter can be rotatably connected, so that the float group can swing on its own according to the horizontal plane and correct the left and right angle difference in real time to make the float reach the best condition; at the same time, the time and energy for manually adjusting the float group to match the left and right angles of the horizontal plane are reduced, so that the oil removal machine can effectively exert the maximum use effect, avoid equipment damage caused by excessive empty suction of the oil removal machine, and extend the service life of the oil removal machine; in addition, the reduction of labor costs, the acceleration of oil removal speed and the reduction of oil removal machine use loss are also conducive to further reducing the investment cost of the enterprise.
