[0007] The oil suction cylinder directly acts on the caustic soda surface under the cooperation of the spring elasticity and the buoyancy of the buoy, and self-adapts to adjust the height along with the liquid level, effectively removes the oil body, and improves the washing efficiency.

[0008] In order to ensure the sealing of the spraying liquid tank,

[0009] As a further improvement of the above technical solution: the bottom side of the detachable cover plate and the top side of the fixed groove are connected with flange sheets, and the fixed groove and the detachable cover plate are fastened and connected through bolts inserted on the flange sheets.

[0010] The improved beneficial effect is that the fixed groove and the detachable cover plate can be stably connected through the bolt structure, avoiding gas leakage from the spraying liquid tank, and the detachable cover plate can be conveniently detached from the fixed groove, facilitating personnel to replace the oil removal assembly.

[0011] In order to ensure the stability of the up and down movement of the oil removal assembly to adapt to different liquid surface heights,

[0012] As a further improvement of the above technical solution: the inner end faces of the fixed groove and the detachable cover plate are respectively formed with lower and upper sliding grooves, the edge parts of the lower and upper sliding grooves are flushly arranged, and the sliding block is slidingly installed in the lower and upper sliding grooves.

[0014] In order to effectively remove the oil body in the liquid,

[0015] As a further improvement of the above technical solution: the oil absorbing cotton is adhered on the curved side surface of the buoy.

[0016] The improved beneficial effect is that the buoy floats in the water body, cooperates with the elastic tension of the extension spring, makes the oil absorbing cotton fully contact with the oil body near the liquid surface, and effectively removes the oil body in the liquid.

[0017] In order to further improve the long-time oil removal effect of the oil removal assembly,

[0018] As a further improvement of the above technical solution: the top end of the flow guide plate is inclinedly arranged towards the direction of the oil removal assembly.

[0019] The improved beneficial effect is that under the guidance of the circulating pump in the pumping circulating pipe and the flow guide plate, the circulating liquid pushes the oil removal assembly to rotate, so that the oil absorbing cotton rolls in contact with the liquid surface, avoiding that the oil absorbing cotton is locally soaked in the liquid surface for a long time to affect the oil removal effect.

[0020] In order to ensure that the oil removal assembly stably floats on the liquid surface,

[0021] As a further improvement of the above technical solution: the float is a sealed hollow cylindrical structure.

[0022] The beneficial effect of the improvement is that the oil removal assembly can stably float on the liquid surface under the support of the buoyancy force received by the float on the water surface.
