Description

Technical Field

[0001] This utility model relates to the field of lubricating oil equipment cleaning, and in particular to a precision lubricating oil processing cleaning device. Background Technology

[0002] Lubricating oil cleaning equipment is a key device used in the production, regeneration, and equipment maintenance of lubricating oil to remove impurities, moisture, and contaminants from the inner walls of oil drums. It is widely used in the cleaning process of lubricating oil drums. Common cleaning equipment includes oil filters, oil purifiers, and oil drum cleaning machines. Among them, oil drum cleaning machines mainly use processes such as spraying, brushing, or rotation to clean the inner walls of oil drums, ensuring that there are no residual contaminants when the oil drums are reused, thus meeting the hygiene and quality requirements for lubricating oil storage and processing.

[0003] To address this, utility model patent CN218797993U discloses a lubricating oil processing and cleaning device. When a lubricating oil drum needs cleaning, the electric lifting rod is energized and pulls the baffle to move the cleaning brush upward, allowing the lubricating oil drum to be placed below the cleaning brush from above. As the electric lifting rod moves again, the cleaning brush moves downward to the inside of the lubricating oil drum. At this time, the motor rotates, driving the cleaning brush to rotate, causing the brush to start brushing the inside of the lubricating oil drum, thus achieving the cleaning effect.

[0004] Mechanical scrubbing is difficult to cover completely, resulting in incomplete cleaning and residual oil or impurities that affect subsequent use. Secondly, when faced with stubborn oil or high-viscosity liquids, the cleaning capacity of a single mechanical cleaning or spraying method is limited, making it difficult to effectively remove contaminants adhering to the inner wall of the oil drum, resulting in incomplete cleaning, and the equipment has poor adaptability.

[0005] Therefore, it is necessary to further improve the cleaning equipment used in lubricating oil processing. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the existing defects and provide a precision cleaning equipment for lubricating oil processing. By combining mechanical cleaning with ultrasonic cleaning, and with a flexible adjustment mechanism and stable clamping design, the cleaning effect and equipment applicability are improved, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a precision lubricating oil processing cleaning device, comprising a cross-shaped fixing frame, a rotating shaft installed in the central hole of the cross-shaped fixing frame, a fixing column provided at the lower end of the rotating shaft, an adjusting rod II provided on the side of the fixing column, a cleaning component installed on the adjusting rod II, and an ultrasonic cleaning component provided on the lower surface of the fixing column.

[0008] A stepper motor is mounted on the motor frame on the upper surface of the cross-shaped fixing frame. The output shaft of the stepper motor is connected to the rotating shaft. A slider is assembled in the slide groove array opened on the upper surface of the cross-shaped fixing frame.

[0009] A linkage component is rotatably mounted on the rotating shaft. The linkage component is connected to the slider. A telescopic component is mounted on the slider. A clamping block is provided on the lower surface of the slider.

[0010] Preferably, the telescopic assembly includes a connecting plate and an electrically controlled push rod, with the connecting plate respectively disposed at both ends of the electrically controlled push rod and disposed on two sliders located on the same axis.

[0011] Preferably, the linkage assembly includes a linkage plate and an angular connecting strip. The linkage plate is rotatably mounted on the outer side of the rotating shaft and located on the upper side of the cross-shaped fixing frame. One end of the angular connecting strip is rotatably mounted at the corner of the linkage plate, and the other end of the angular connecting strip is rotatably mounted on the slider.

[0012] Preferably, the cleaning assembly includes a cleaning plate, an extension plate, and cleaning strips. The cleaning plate is disposed at the end of the adjusting rod two. The extension plate is slidably fitted in the lower opening groove of the cleaning plate. The extension plate is connected to the cleaning plate through the adjusting assembly. The cleaning strips are distributed on the arc-shaped contact surface of the cleaning plate and the extension plate.

[0013] Preferably, the adjustment component includes adjustment holes and a fixing strip. The adjustment holes are arrayed on the cleaning plate along the length direction of the cleaning plate, and the fixing strip is installed on the extension plate. A pull ring self-locking pin is installed on the fixing strip and is inserted into the adjustment hole.

[0014] Preferably, the ultrasonic cleaning assembly includes a connecting rod and an ultrasonic transducer, the ultrasonic transducer being mounted on the lower end of the connecting rod, and the connecting rod being disposed on the lower surface of the fixed column.

[0015] Preferably, it also includes an adjusting rod one, the two ends of which are respectively hinged to an adjusting rod two and an extension plate.

[0016] The working principle and application principle of this utility model are as follows:

[0017] Working principle: The rotating shaft is driven by a stepper motor to rotate, and the clamping block is linked to fix the lubricating oil processing barrel. The cleaning component performs mechanical brushing, and the ultrasonic cleaning component assists in deep cleaning. Adjusting rod one and adjusting rod two adjust the position and length of the cleaning component. The telescopic component and the linkage component ensure the precise positioning of the clamping block. The synergy between mechanical cleaning and ultrasonic cleaning achieves all-round cleaning of the inner wall of the lubricating oil processing barrel.

[0018] Instructions for use: Place the equipment inside the lubricating oil processing barrel, with the cross-shaped fixing bracket fitting against the upper surface of the barrel. Adjust the length of the second adjusting rod to ensure the cleaning component fits against the inner wall of the barrel. Inject an appropriate amount of cleaning fluid into the barrel to ensure the ultrasonic transducer is submerged. The external controller controls the retraction of the electric push rod, which moves the slider. The slider drives the linkage component to rotate on the rotating shaft, causing the other sliders to slide. The sliders then move the clamping blocks, thus completing the centering and clamping of the lubricating oil processing barrel and ensuring the rotating shaft is centered within the barrel.

[0019] An external controller controls the ultrasonic cleaning component and the stepper motor. The stepper motor drives the rotating shaft to rotate slowly, causing the cleaning component and the ultrasonic cleaning component to rotate synchronously. The cleaning strip rotates and brushes the inner wall of the lubricating oil processing tank. The ultrasonic transducer generates high-frequency vibration, forming microbubbles in the cleaning fluid and instantly breaking them through cavitation effect, thus removing stubborn oil stains from the inner wall of the lubricating oil processing tank. After cleaning, the cleaning fluid containing oil stains is discharged through the drain port of the lubricating oil processing tank itself.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By combining the cleaning components and ultrasonic cleaning components, mechanical brushing and ultrasonic cleaning are combined to effectively remove stubborn oil stains and dead-angle dirt from the inner wall of the lubricating oil processing barrel.

[0022] 2. The telescopic and linkage components provide precise clamping and positioning functions to adapt to lubricating oil processing barrels of different sizes;

[0023] 3. The adjustment design of adjustment rod one and adjustment rod two enhances the adaptability of the cleaning components to the inner wall of the lubricating oil processing tank. The overall structure of the equipment is compact, the cleaning efficiency is high, and the maintenance cost is low. Attached Figure Description

[0030] Please see Figure 1-3 The present invention provides the following technical solution: a precision cleaning device for lubricating oil processing, including a cross-shaped fixing frame 1, a rotating shaft 12 installed in the center hole of the cross-shaped fixing frame 1, a fixing column 7 provided at the lower end of the rotating shaft 12, an adjusting rod 2 11 provided on the side of the fixing column 7, a cleaning component 4 installed on the adjusting rod 2 11, and an ultrasonic cleaning component 8 provided on the lower surface of the fixing column 7.

[0031] Specifically, the rotating shaft 12 is installed in the center hole of the cross bracket 1 through a bearing, which facilitates the rotation of the rotating shaft 12. The rotating shaft 12 can drive the cleaning component 4 and the ultrasonic cleaning component 8 to rotate through the fixed column 7. The adjusting rod 11 is a common lockable telescopic adjusting rod on the market, which is used to adjust the position of the cleaning component 4 according to the diameter of the lubricating oil processing barrel, so as to ensure that the cleaning component 4 can adapt to lubricating oil processing barrels of different diameters. The cleaning component 4 performs mechanical brushing on the inner wall of the lubricating oil processing barrel. The ultrasonic cleaning component 8 achieves deep cleaning of the inner wall of the lubricating oil processing barrel through ultrasonic vibration, removing stubborn oil stains.

[0032] The cross-shaped fixing bracket 1 serves as the support structure of the equipment, and the bearing in the central hole ensures the smooth rotation of the rotating shaft 12; the fixing column 7 is fixed to the lower end of the rotating shaft 12, providing an installation base for the adjusting rod 11 and the ultrasonic cleaning assembly 8;

[0033] The cross-shaped fixing bracket 1 and the fixing column 7 can be made of cast iron or stainless steel to ensure strength and corrosion resistance, and the rotating shaft 12 can be made of high-strength alloy steel to ensure wear resistance and durability.

[0034] A stepper motor 5 is mounted on the motor frame on the upper surface of the cross-shaped fixing frame 1. The output shaft of the stepper motor 5 is connected to the rotating shaft 12. A slider 13 is assembled in the slide groove array opened on the upper surface of the cross-shaped fixing frame 1.

[0035] Specifically, the motor frame provides stable support for the stepper motor 5. The output shaft of the stepper motor 5 is connected to the rotating shaft 12 through a coupling to ensure power transmission. The operation of the stepper motor 5 can drive the rotation of the rotating shaft 12. The slide groove and slider 13 achieve radial movement of the clamping block 3 through sliding cooperation. The slide groove and slider 13 are designed to facilitate adjustment of the position of the clamping block 3 and adapt to different specifications of lubricating oil processing barrels.

[0036] A linkage component 6 is rotatably mounted on the rotating shaft 12. The linkage component 6 is connected to the slider 13. A telescopic component 2 is mounted on the slider 13. A clamping block 3 is provided on the lower surface of the slider 13.

[0037] Specifically, the extension and retraction of the telescopic component 2 drives the movement of the two opposing sliders 13. The sliders 13 drive the linkage component 6 to rotate on the rotating shaft 12, causing the remaining sliders 13 to slide. The sliders 13 drive the movement of the clamping block 3, thereby completing the centering and clamping of the lubricating oil processing barrel, ensuring that the rotating shaft 12 is located in the center of the lubricating oil processing barrel, which facilitates the cleaning of the lubricating oil processing barrel.

[0038] Furthermore, the telescopic assembly 2 includes a connecting plate 201 and an electrically controlled push rod 202. The connecting plate 201 is respectively disposed at both ends of the electrically controlled push rod 202, and the connecting plate 201 is disposed on two sliders 13 located in the coaxial direction.

[0039] Specifically, the drive electric control push rod 202 drives the two sliders 13 in the same direction to move through the connecting plate 201, providing force for the rotation of the linkage plate 601. The connecting plate 201 can be made of high-strength steel plate to ensure rigidity.

[0040] When the electric push rod 202 retracts, the slider 13 moves toward the rotating shaft 12, and at the same time the linkage plate 601 rotates counterclockwise. At this time, the lubricating oil processing barrel can be clamped.

[0041] Conversely, when the electrically controlled push rod 202 retracts, the linkage plate 601 rotates clockwise, which can release the lubricating oil processing barrel.

[0042] Furthermore, the linkage component 6 includes a linkage plate 601 and an angled connecting strip 602. The linkage plate 601 is rotatably mounted on the outer side of the rotating shaft 12 and located on the upper side of the cross-shaped fixing frame 1. One end of the angled connecting strip 602 is rotatably mounted at the corner of the linkage plate 601, and the other end of the angled connecting strip 602 is rotatably mounted on the slider 13.

[0043] Specifically, the linkage plate 601 is a square plate, and the number of the angled connecting strips 602 is the same as the number of sliders 13. The sliders 13 slide along the slide groove, and can drive the linkage plate 601 to rotate on the rotating shaft 12 through the angled connecting strips 602, while driving the movement of other sliders 13, so as to realize the synchronous positioning of the clamping block 3 on the lubricating oil processing barrel.

[0044] The linkage plate 601 is connected to the rotating shaft 12 via a bearing to ensure flexible rotation; the angled connecting strip 602 connects the linkage plate 601 and the slider 13 via a hinge, converting the rotational motion into sliding motion and realizing the synchronous radial movement of the slider 13.

[0045] Furthermore, the cleaning component 4 includes a cleaning plate 401, an extension plate 402, and a cleaning strip 403. The cleaning plate 401 is disposed at the end of the adjusting rod 11. The extension plate 402 is slidably mounted in the lower opening groove of the cleaning plate 401 through a sliding member. The extension plate 402 is connected to the cleaning plate 401 through the adjusting component 10. The cleaning strip 403 is distributed on the arc-shaped contact surface of the cleaning plate 401 and the extension plate 402.

[0046] Specifically, the cleaning strips 403 on the cleaning plate 401 and the extension plate 402 rotate and scrub the inner wall of the lubricating oil processing barrel to remove oil and impurities;

[0047] Adjust the length of the adjusting rod 11 so that the cleaning strips 403 on the cleaning plate 401 and the extension plate 402 contact the inner wall of the lubricating oil processing barrel. Set the extension length of the extension plate 402 through the adjusting component 10 to suit the height of the lubricating oil processing barrel. The rotating shaft 12 drives the cleaning strips 403 to rotate and brush through the adjusting rod 11 to achieve mechanical cleaning of the inner wall of the lubricating oil processing barrel.

[0048] The cleaning plate 401 and the extension plate 402 are provided with arc-shaped outer surfaces, and the cleaning strips 403 are distributed in an arc shape to cover more cleaning area. The cleaning plate 401 and the extension plate 402 can be made of stainless steel for corrosion resistance, and the cleaning strips 403 can be made of wear-resistant nylon or polypropylene to ensure cleaning effect and durability.

[0049] Furthermore, the adjustment assembly 10 includes an adjustment hole 1001 and a fixing strip 1002. The adjustment hole 1001 is arrayed on the cleaning plate 401 along the length direction of the cleaning plate 401. The fixing strip 1002 is installed on the extension plate 402, and a pull ring self-locking pin is installed on the fixing strip 1002. The pull ring self-locking pin is inserted into the adjustment hole 1001.

[0050] Specifically, by inserting the pull ring self-locking pin into the adjustment holes 1001 at different heights, the extension length of the extension plate 402 relative to the cleaning plate 401 is fixed, thereby adjusting the cleaning range of the cleaning component 4. The pull ring self-locking pin achieves quick locking through insertion, and the length of the cleaning component 4 can be adjusted according to the height of the lubricating oil processing barrel. The adjustment is simple and quick, and the operation is convenient.

[0051] Furthermore, the ultrasonic cleaning assembly 8 includes a connecting rod 801 and an ultrasonic transducer 802. The ultrasonic transducer 802 is installed at the lower end of the connecting rod 801, and the connecting rod 801 is disposed on the lower surface of the fixed column 7.

[0052] Specifically, the ultrasonic transducer 802 generates high-frequency vibrations, forming microbubbles in the cleaning fluid and instantly bursting to create a cavitation effect, thereby removing stubborn oil stains from the inner wall of the lubricating oil processing barrel. The connecting rod 801 is fixed to the lower surface of the fixed column 7 to provide stable support for the ultrasonic transducer 802. The ultrasonic transducer 802 generates ultrasonic waves through electrical signal drive.

[0053] Inject cleaning fluid into the lubricating oil processing tank, start the ultrasonic transducer 802, and perform deep cleaning in conjunction with the mechanical brushing of the cleaning component 4. The cleaning effect is enhanced by the ultrasonic cavitation effect, which is especially effective for stubborn oil stains. The combination with mechanical cleaning improves the overall cleaning efficiency.

[0054] The device also includes an adjusting rod 9, the two ends of which are hinged to an adjusting rod 11 and an extension plate 402, respectively.

[0055] Specifically, the adjusting rod 9 is a common lockable telescopic adjusting rod on the market. The adjusting rod 9 can increase the strength of the extension plate 402. When the extension plate 402 is adjusted, the adjusting rod 9 can adjust the length accordingly to ensure that the cleaning component 4 fits the inner wall of the lubricating oil processing barrel more closely.

[0056] It is worth noting that the input terminals of the stepper motor 5, the electrically controlled push rod 202, and the ultrasonic transducer 802 are electrically connected to the output terminal of the external controller. The ultrasonic transducer 802 can be connected to the external controller through a slip ring to prevent cable tangling. The slip ring can be installed on the rotating shaft 12. The stepper motor 5 can be a NEMA 17 hybrid stepper motor from Mingzhi Electric, the electrically controlled push rod 202 can be a DLA-B model from Dingtuoda Electromechanical, and the ultrasonic transducer 802 can be a JC-28K-80W model from Beijing Jinchao Technology.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
