Description
Technical Field

Background
Lubricating oils are composed of 80-90% base oil and 10-20% additives, with the main chemical components being a mixture of various hydrocarbons and small amounts of non-hydrocarbons. However, after the lubricating oil is used for a period of time, the performance of the lubricating oil is deteriorated due to physical chemistry or human factors, so that pollutants such as ketone, aldehyde, resin, asphalt colloid substances, carbon black, organic acid, salt, water, metal scraps and the like are generated, and the lubricating oil cannot be used any more and becomes waste lubricating oil. In practice, the waste oil is not wasted, the used lubricating oil truly deteriorates by a few percent, and the regenerated lubricating oil with the same performance as a new product can be obtained by removing impurities in the waste oil.
In the prior art, a plurality of filtering modes are adopted to filter the recovered lubricating oil, wherein, the membrane separation method is a simple and efficient separation filtering mode. Considering the poor viscosity and high fluidity of waste lubricating oil, the prior art has the problem that the filtration flux and the pollution resistance of a membrane unit are improved when the membrane unit is used for filtering the lubricating oil. The existing vibrating diaphragm separation units are all provided with a vibrating disc on one torsion bar, and the vibrating disc generates rotary vibration through rotary vibration of a centrifugal vibrating original piece at the bottom of the torsion bar. However, for filtering of lubricating oil, the centrifugal force of the membrane unit is smaller when the membrane unit is closer to the rotating center, and the shearing action generated on the membrane unit is weaker, so that more oil stains of the lubricating oil are accumulated when the membrane unit is closer to the center, less oil stains are accumulated when the membrane unit is farther from the center, and uneven accumulation of pollutants is unfavorable for efficient cleaning of the membrane unit and also unfavorable for filtering of the lubricating oil.
Therefore, it is necessary to design a filtering structure of a lubricating oil vibrating membrane unit, which can effectively avoid uneven oil dirt accumulation of the membrane unit at the center of the membrane unit, and improve the shearing action of the center of the membrane unit, thereby further improving the anti-pollution capability of the membrane unit.

Detailed Description
The following detailed description of the invention refers to the accompanying drawings and preferred embodiments.
As shown in fig. 1, the lubricating oil filtering and recovering device of the present application includes a base 1, a base diaphragm filtering unit 2, a center diaphragm unit 3, and a lubricating oil filtering pipe group 4. The base 1 is a circular disc-shaped base, the central vibrating unit 3 is arranged at the central position of the base 1, and the plurality of basic vibrating membrane filtering units 2 are arranged on the base 1 in a central symmetry mode relative to the central vibrating unit 3. The number of the basic diaphragm filter units 2 in the present application is at least two, and the lubricating oil filtering and recovering device of the present application will be described below by taking two basic diaphragm filter units 2 as an example.
The basic diaphragm filter unit 2 of the present application is shown in fig. 2. It includes a vibration plate 21, a centrifugal vibration unit 22, a torsion bar 23, a torsion bar coupler 24, and a membrane unit 25. Wherein, vibration dish 1 is installed on base 1 through the bolt mounting structure of bottom, and vibration dish 21 is circular disk structure, installs centrifugal vibration unit 22 in the quotation edge position of vibration dish 21. The centrifugal vibration unit 22 is composed of a high-frequency motor, a high-speed output shaft, and a centrifugal block mounted on the high-speed output shaft, the high-speed output shaft being connected to an output end of the high-frequency motor, and when the high-frequency motor is started, the high-speed output shaft is driven to rotate at a high speed to drive the centrifugal block to rotate, thereby generating high-frequency vibration. The torsion bar 23 is a torsion bar of a long shaft, and is mounted at a top center position of the vibration plate 21 by a flange bolt. At the top of torsion bar 23, install membrane unit 25, membrane unit 25 is conventional circular flat membrane, and membrane unit 25 top is provided with two oil inlets, and the bottom is provided with two oil-out, and the top center is provided with the concentrate export. The oil inlet, the oil outlet and the concentrated liquid outlet of the membrane unit 25 are connected with the lubricating oil filtering pipeline group 4. Further, at a position where the torsion bar 23 is close to the membrane unit 25, a torsion bar coupler 24 is provided, and the torsion bar coupler 24 divides the torsion bar 23 into two parts. The high-frequency vibration generated by the centrifugal vibration unit 22 is finally transmitted to the membrane unit 25 through the transmission of the vibration plate 21, the torsion bar 23, and thereby the membrane unit 25 generates high-frequency oscillation about the center axis of the torsion bar 23. This high frequency oscillation increases the shearing action of the lubricating oil flowing through the membrane unit 25, thereby increasing the filtration flux and the contamination resistance of the membrane unit 25.
However, since the high-frequency vibration generated by each base diaphragm filter unit 2 is a rotational oscillation of the diaphragm unit 25 about its central axis, as shown in fig. 3, which is a top view of the diaphragm unit 25, in actual production, since the viscosity of recovered lubricating oil, impurities are high, and the centrifugal force thereof is small in the region of the diaphragm unit 25 near the center of its oscillation, the shearing action is weak, and thus the membrane pollution in the central region of the diaphragm unit 25 is large. In order to improve the anti-pollution capability of the center of the membrane unit 25 on the base vibrating membrane filter unit 2, as shown in fig. 1, the application is to arrange two base vibrating membrane filter units 2 on the base 1 in a central symmetry manner, and simultaneously, a central vibrating unit 3 is arranged at the central position of the base 1.
The central vibration unit 3 is vertically arranged at the central position of the base 1, and comprises a lifting cylinder 31, a small vibration disc 32, a central centrifugal vibration unit 33, a central torsion bar 34, a large vibration disc 35 and a coupling pressure bar 36. The lifting cylinder 31 is arranged at the center of the base 1, the small vibration plate 32 is arranged at the tail end of the telescopic rod of the lifting cylinder 31 through a bolt flange, and the center vibration unit 33 is arranged at the top edge of the small vibration plate 32. The structures and forms of the small vibration plate 32 and the center centrifugal vibration unit 33 are identical to those of the vibration plate 21 and the centrifugal vibration unit 22 of the base diaphragm filter unit 2. On top of the small vibration plate 32, a center torsion bar 34 is mounted by a bolt flange, the top of the center torsion bar 34 is higher than the base diaphragm filter unit 2, and on top of the center torsion bar 34, a large vibration plate 35 is mounted by a bolt flange. The large vibration disk 35 is of a disk structure, the diameter of the large vibration disk 35 covers the range of the surrounding basic vibration film filtering units 2, a plurality of sleeve holes 351 are arranged on the large vibration disk 35 in a central symmetry mode, the number and the positions of the sleeve holes 351 are matched with the film units 25 of each basic vibration film filtering unit 2, and the diameter of the sleeve holes 351 is matched with the diameter of the film units 25. As shown in fig. 5, when the lifting cylinder 31 at the bottom is extended, the large vibration plate 35 is lifted above the membrane units 25, and when the lifting cylinder 31 is contracted, the large vibration plate 35 is lowered while the sleeve hole 351 on the large vibration plate 35 is fitted over the membrane unit 25 of each base diaphragm filter unit 2.
Furthermore, a coupling strut 36 is provided on the central torsion bar 34 of the central vibrating unit 3, the coupling strut 36 being approximately flush with the torsion bar coupling 24 of the basic vibrating membrane filter unit 2. As shown in fig. 6, a vertical presser head 361 is provided at the end of the coupling presser bar 36, and the presser head 361 extends above the torsion bar coupling 24. The torsion bar coupler 24 includes an upper coupler 241 and a lower coupler 242, a spring pin 243 is provided between the upper coupler 241 and the lower coupler 242, the spring pin 243 has a long bar shape in cross section, the spring pin 243 is spring-jacked in a conventional state to connect the upper coupler 241 and the lower coupler 242, and when the lift cylinder 31 is contracted, the center torsion bar 34 drives the coupler strut 36 to descend, so that the driving ram head 361 presses down the spring pin 243 on the torsion bar coupler 24, thereby separating the upper coupler 241 and the lower coupler 242.
In the working mode of the lubricating oil filtering and recovering device, as shown in fig. 5, in a normal state, the lifting cylinder 31 extends out, at this time, the central vibrating unit 3 is separated from the peripheral basic vibrating membrane filtering units 2, the torsion bar coupler 24 of the basic vibrating membrane filtering units 2 is not separated, only the centrifugal vibrating unit 22 on the basic vibrating membrane filtering units 2 works to generate high-frequency vibration, and the membrane unit 25 generates high-frequency rotation vibration around the central axis thereof; after the normal state is operated for a certain time, the deep cleaning mode is started, at this time, the lifting cylinder 31 is contracted, the central torsion bar 34 is lowered, the large vibration disc 35 is lowered, and the sleeve hole 351 on the large vibration disc 35 is sleeved on the membrane unit 25 of each basic vibration membrane filtration unit 2, thereby connecting the central vibration unit 3 with the peripheral basic vibration membrane filtration units 2, and at the same time, the torsion bar coupler 24 is separated due to the downward pressing of the coupler pressing rod 36, thereby separating the membrane unit 25 from the torsion bar 23, at this time, the central centrifugal vibration unit 33 of the central vibration unit 3 works, and the centrifugal vibration unit 22 stops working, thereby enabling the membrane unit 25 to integrally generate high-frequency swing vibration around the axis of the central torsion bar 34, and improving the centrifugal force and shearing action of the central area of each membrane unit 25, thereby improving the anti-pollution capability of the membrane unit.
Since the number of the basic diaphragm filter units 2 in the present application is at least two, in addition to the above-described embodiments of the two basic diaphragm filter units 2, the present application may also provide three, four or more basic diaphragm filter units 2 installed centrally symmetrically.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
