Under the background, environmental-friendly and energy-saving hydraulic transmission technologies are researched in various countries in the world, and the main development direction of the technology is to develop biodegradable hydraulic oil. The biodegradable hydraulic oil can meet the requirements of a machine hydraulic system, and the waste products of the hydraulic oil do not harm the environment. Biodegradability means the decomposition of a substance into CO by living organisms by biological action2And H2The capacity of O. The biodegradable hydraulic oil is composed of base oil and additives as common mineral hydraulic oil. But the degradable performance determines the structure of base oil and additive and the common mineral hydraulic pressureThe oil is different.
When biological lubricating oil is carried out, polyol ester is put into a distillation retort for reduced pressure distillation, hydrogen peroxide is added for standing and layering, when the water on the lower layer is discharged by the conventional distillation retort, and when the liquid at the boundary of the water and the oil is discharged from the distillation retort, due to the fact that the residual height of the water level is not known, after a part of oil liquid is discharged, a worker can timely and quickly close a discharge port at the bottom of the distillation retort, waste of the oil liquid is prevented, and meanwhile, complete separation of the oil and the water cannot be realized; in view of this, the invention provides a lubricating oil distillation tank, which can automatically close a discharge port after water is discharged, so that the waste of resources is reduced.

An annular cylinder 14 is arranged at the top of the discharge port 3, and the height of the annular cylinder 14 is 5-10 cm; because the boundary of the layered water and the polyol ester has a small amount of mixed layers, the top of the discharge port 3 is provided with the annular cylinder 14, after the movable disc 4 contacts the annular cylinder 14, the two seal plates 6 are extruded to the annular cylinder 14, the square through hole 5 is in a closed state, and finally, part of mixed liquid at the bottom of the movable disc 4 is blocked in the tank body 1 through the action of the annular cylinder 14, so that the waste of resources is reduced.
The top of the annular cylinder 14 is fixedly connected with a plurality of hemispherical covers 15, two adjacent hemispherical covers 15 are in contact, and a supplement port 16 is formed in the position, away from the central axis of the annular cylinder 14, of each hemispherical cover 15; when the initial moving plate 4 is not lowered, the inside of the dome cover 15 is filled with water, and after the two closing plates 6 are lowered and the water in the dome cover 15 is finally pushed out by the gravity of the polyol ester, the water level can be raised, the height of the polyol ester can be finally raised, the height of the mixed layer can be finally raised, and the amount of the polyol ester remaining in the tank body 1 can be further increased.
An oil-water separating agent is placed in the bearing air bag 31, and in an initial state, the oil-water separating agent cannot realize the increase of the aperture of the pinhole in the bearing air bag 31; the oil-water separating agent is HMD-01; by adding the oil-water separating agent, the water containing the polyol ester can be quickly layered with the polyol ester, so that the oil-water layering efficiency is further improved; meanwhile, the HMD-01 oil-water separating agent is selected, and the product of the oil-water separating agent has the advantages of high ionic strength, stability in storage, wide pH value range adaptation, no toxicity, safety in use, high clarifying speed, good condensation effect and good oil-water layering effect, so that the oil-water layering effect of the distillation retort is improved.
When the device works, polyol ester is put into a distillation retort for reduced pressure distillation, an organic solvent is evaporated, formic acid is added and heated, hydrogen peroxide is added dropwise, after dropwise addition is finished, heat is preserved for 2 hours, standing and layering are carried out, the height of the water level of the polyol ester after standing and layering is within a certain range, as the movable disc 4 is made of a light material and is internally provided with a plurality of cavities, the movable disc 4 can be suspended on the water surface and sink to the bottom of the polyol ester and just suspend at the boundary of the water and the polyol ester after layering, after the discharge port 3 is opened, the movable disc 4 descends along with the descending of the water level in the process of descending of the water, the two seal plates 6 are hollow when being manufactured, the two seal plates 6 deflect downwards to the state that the deflection angle is less than ninety degrees from the state of contact, when the movable disc 4 descends along with the descending of the water level, the movable disc 4 drives the seal plates 6 to move downwards, when water is discharged from the discharge port 3, the movable disc 4 reaches the bottommost end, the weight of the polyol ester above the movable disc 4 can extrude the movable disc 4 downwards, and finally the movable disc 4 extrudes the two sealing plates 6 to enable the two sealing plates 6 to be in a contact state, so that the square through hole 5 is blocked, the automatic closing of the discharge port 3 is finally realized, workers can process other matters, and then the workers find that the discharge port 3 does not leak any more, the water is completely discharged, and the condition of resource waste caused by the fact that the workers do not close the discharge port 3 in time can be prevented; at this time, some polyol ester still exists in the effluent water, which is easy to damage the environment and cause polyol ester waste, the effluent water containing polyol ester enters the bearing air bag 31 by installing the bearing air bag 31 at the discharge port 3, the pore diameter of the reserved pinholes in the bearing air bag 31 is gradually increased (the gradually increased pinhole pore diameter is still far smaller than the diameter of the discharge port 3) along with the increase of the water containing polyol ester, and then the effluent water flows out from the increased pinholes; the water containing the polyol ester flows into the bearing air bag 31 in a large caliber, then flows out of the bearing air bag 31 in a small caliber, so that the layering of the water containing the polyol ester is realized, the discharge of the polyol ester is reduced, the harm to the environment and the waste to the polyol ester are reduced, the utilization rate of the polyol ester is improved, and the market applicability of the distillation retort is improved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
