Of course, they are merely examples and are not intended to limit the present invention.

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0035] Example:
[0036] See also Figure 1 This embodiment discloses a circulating purification system comprising a filter 10, an evaporator 20, and a density detector 30. Specifically, the filter 10 has an input port through which lubricating oil to be purified is fed. The evaporator 20 is connected to the output port of the filter 10. A condenser 50 is connected to the top of the evaporator 20. This condenser 50 condenses the light components evaporated from the lubricating oil into a liquid state for subsequent processing.
[0037] The density detector 30 is communicated with the output end of the evaporator 20 . The density detector 30 has an unqualified output end and a qualified output end. The unqualified output end is connected to the input end of the evaporator 20 .
[0038] Preferably, a gear pump 40 is provided between the output end of the filter 10 and the input end of the evaporator 20, a gear pump 40 is also provided between the output end of the evaporator 20 and the input end of the density detector 30, and a gear pump 40 is also provided between the unqualified output end of the density detector 30 and the input end of the evaporator 20.
[0039] By designing a plurality of gear pumps 40 , the lubricating oil can be driven to flow in the system efficiently.
[0040] In this technical solution, filter 10 is first designed to separate the heavy components in the lubricating oil. The lubricating oil cleaned of the heavy components is then fed into evaporator 20, where the light components in the lubricating oil are cleaned. A density detector 30 is then designed to detect whether the density of the treated lubricating oil is within the required range, thereby determining whether the treated lubricating oil meets the standards. If so, it is directly discharged; if not, it is recycled into evaporator 20. This technical solution ensures that all treated lubricating oil meets the requirements for reuse.
[0041] In one specific embodiment:
[0042] See also Figure 2 The density detector 30 includes a housing, a support plate 31, a drive plate 32, a tank 33, a platform scale 34, an emptying assembly, and a motor 35. The support plate 31 and the drive plate 32 are both circular, with the diameter of the support plate 31 being equal to the diameter of the drive plate 32 and being coaxially arranged. The support plate 31 is located below the drive plate 32, with a gap between them.
[0043] A through hole is provided in the middle of the support plate 31 , and a test hole is provided on the side of the support plate 31 , wherein the four sides of the support plate 31 are fixedly connected to the inner wall of the housing.
[0044] The aforementioned motor 35 is fixedly installed in the housing, and the output shaft of the motor 35 is vertically upward. At the same time, the motor 35 is also arranged in the through hole of the support plate 31. A drive plate 32 is arranged on the output shaft of the motor 35, and the drive plate 32 is coaxially arranged with the output shaft of the motor 35.
[0045] The driving plate 32 has a plurality of driving holes, and all the driving holes are evenly distributed around the axis of the driving plate 32 . A tank body 33 is placed in each driving hole, and the tank body 33 is a structure with an open top.
[0046] The platform scale 34 is set in the test hole of the support plate 31, and the top surface of the platform scale 34 is on the same plane as the top surface of the support plate 31. The emptying assembly is set above the two tanks 33, so there are also two emptying assemblies.
[0047] In this embodiment, purified lubricating oil is input into the tank body 33 through a delivery pipe arranged above the tank body 33. After a certain amount of lubricating oil is delivered, the motor 35 drives the drive plate 32 to rotate a certain angle, so that the tank body 33 slides on the support plate 31, and the tank body 33 filled with lubricating oil moves to the top of the scale 34. The scale 34 bears the weight of the lubricating oil in the tank body 33. The density of the lubricating oil can be calculated in combination with the weight and volume of the lubricating oil, and is compared with the required density to determine whether it is qualified.
[0048] Preferably, the mouth of the delivery pipe is vertically downward, and a solenoid valve and a flow meter are provided on the delivery pipe. The opening and closing of the delivery pipe are controlled by the solenoid valve, and the amount of lubricating oil delivered in a single time is counted by the flow meter.
[0049] In another specific embodiment:
[0050] There are at least three tanks 33, and at least three drive holes are also formed on the drive plate 32. In this embodiment, four tanks 33 are used as an example. Under normal circumstances, there is exactly one tank 33 on the platform scale 34, exactly one tank 33 under the delivery pipe, and one tank 33 under each of the two emptying components.
[0051] With this design, the work of receiving lubricating oil in the tank 33, weighing on the scale 34, and outputting the emptying component can be carried out separately without confusion.
[0052] Since the driving plate 32 can drive one tank 33 from the bottom of the conveying pipe to the scale 34 each time, the driving plate 32 rotates 360° divided by the number of tanks 33 each time, which is 360° / 4 in this embodiment, so the driving plate 32 rotates 90° each time.
[0053] In another specific embodiment:
[0054] The emptying assembly includes a hose 36 and a telescopic member 37, wherein one end of the hose 36 is located above a tank body 33, and the telescopic end of the telescopic member 37 is connected to the end of the hose 36. The telescopic member 37 can drive the end of the hose 36 into the tank body 33 and make it close to the bottom of the tank body 33, thereby facilitating the discharge of all the lubricating oil in the tank body 33. In addition, the telescopic end of the telescopic member 37 can also drive the end of the hose 36 to the outside of the tank body 33 to facilitate the rotation of the tank body 33.
[0055] The telescopic member 37 is a pneumatic cylinder or a hydraulic cylinder, and the telescopic end of the telescopic member 37 is a piston rod of the pneumatic cylinder or the hydraulic cylinder.
[0056] In this embodiment, the two emptying components correspond to the unqualified output end and the qualified output end of the density detector 30 respectively.
[0057] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
