The adsorption device 1 of the present embodiment includes a water suction pipe 11, a moving member 12, a telescopic sleeve 13, and a mounting plate 14.
One end of the water pumping pipe 11 in the embodiment is closed, a water pumping hole 111 is arranged on the water pumping pipe 11, and negative pressure is generated in the water pumping pipe 11 during operation, so that liquid is absorbed from the water pumping hole 111. In this embodiment, the vacuum pump 6 may be used to achieve a negative pressure in the water suction pipe 11.
The moving member 12 in this embodiment is slidably sleeved on the pumping pipe 11 along the pumping pipe 11, and the moving member 12 and the pumping pipe 11 have a gap in a radial direction, and a suction port 121 is formed at a lower portion of the gap. This embodiment draws liquid into the gap through the suction port 121 and into the pump hole 111.
The telescopic sleeve 13 in this embodiment has a bottom surface 131 fixed to the closed end of the pumping pipe 11, a side surface 132 capable of extending and contracting along the axial direction of the pumping pipe 11, and a top surface 133 connected to the moving member 12, at least the side surface 132 of the telescopic sleeve 13 is configured to allow liquid to pass through, and when the side surface 132 extends and contracts along the axial direction of the pumping pipe 11, the top surface 133 drives the moving member 12 to move along the axial direction of the pumping pipe 11, so that the position of the suction inlet 121 can be adjusted to adapt to the actual liquid level.

The side 132 of the present embodiment is configured to expand after absorbing the liquid, thereby expanding and contracting the side 132 along the pumping pipe 11. Specifically, the side 132 absorbs the liquid (water or oil) and expands due to the material relationship, so that the overall height of the side 132 increases, and the top 133 is driven to rise, and when the top 133 rises, the moving member 12 is driven to rise, thereby completing the position adjustment of the suction inlet 121. That is, when the bellows 13 is excessively immersed in the liquid, the position of the suction port 121 becomes high to prevent excessive suction of water located at the opposite lower layer.

The moving member 12 of this embodiment has a buoyancy structure to increase the buoyancy of the moving member 12. If the buoyancy on the moving member 12 is insufficient, a large amount of water may be introduced because the moving member 12 is completely submerged in the upper portion of the gap between the moving member 12 and the pumping pipe 11. The buoyancy structure is provided to increase the buoyancy of the moving member 12 and prevent it from being completely submerged.
In some embodiments, as shown in fig. 5, the buoyancy structure is a groove 122 provided on the upper surface of the moving member 12.
In some embodiments, as shown in fig. 4, the buoyancy structure is a closed cavity 123 disposed in an upper portion of the moving member 12.
In this embodiment, the moving member 12 has an annular mounting groove 124, and the inner edge of the top surface 133 of the telescopic sleeve 13 is locked in the mounting groove 124. If the telescopic sleeve 13 is made of soft material such as rubber, the detachable connection can be realized by the above structure.
The suction port 121 in this embodiment is located at a position lower than the pumping hole 111. To dynamically adjust and absorb the upper layer oil by utilizing the characteristic that the position of the suction inlet 121 is adjustable.
The mounting plate 14 in this embodiment is fixed to the end of the water pumping pipe 11, so that one end of the water pumping pipe 11 is closed, and the bottom surface 131 of the telescopic sleeve 13 is fixed to the mounting plate 14. Specifically, the bottom surface 131 may be bolted to the mounting plate 14.

In an embodiment, the height of the water outlet 2123 is equal to or slightly higher than the height of the oil spill 213, for example, the height of the water outlet 2123 is 0 to 5mm higher than the height of the oil spill 213. After the liquid inlet pipe 22 is filled with liquid, the liquid level in the accommodating cavity 211 rises, so that the oil floating on the water surface enters the first bin 211 through the oil overflow port 213. The height relationship between the water outlet 2123 and the spillway 213 can control the liquid level and thus the oil layer thickness. If the liquid level in the accommodating cavity 211 is too high, the oil layer is too thin, the oil spilling opening 213 will flow out water to the first bin 211, and if the liquid level in the accommodating cavity 211 is too low, the oil spilling opening 213 will need to accumulate oil for a longer time or will not flow out oil if the oil layer is too thick.
The embodiment has simple structure and reasonable design; when in use, clean water is injected into the accommodating cavity 211, the liquid level of which is slightly lower than the oil spilling port 213, then waste liquid is injected into the accommodating cavity 211 through the liquid inlet pipe 22, oil in the waste liquid floats on the water surface due to the fact that the density of the oil is smaller than that of the water, flows into the first bin 211 through the oil spilling port 213, and is recovered or collected from the oil collecting port 2111 of the first bin 211; the cutting fluid purifying and filtering device has the advantages of high separation efficiency, low cost, small volume and simplicity in operation.
