Description

Technical Field

[0001] This utility model relates to the technical field of hydrocarbon vacuum cleaning machines, and specifically to a fully automatic multi-tank vacuum hydrocarbon cleaning machine. Background Technology

[0002] In the field of precision machinery manufacturing, effectively removing grease, dirt, and microparticles from the surface of parts while avoiding damage to the workpiece during the cleaning process is a critical requirement. Hydrocarbon vacuum cleaning technology is widely used due to its excellent environmental friendliness and safety. This technology uses specific hydrocarbons as the cleaning medium and performs cleaning operations in a vacuum environment. The vacuum environment effectively lowers the boiling point of the cleaning medium, enhances its permeability and fluidity, and inhibits volatilization, reducing consumption. This combination can efficiently dissolve and remove grease-based contaminants while avoiding problems such as corrosion, oxidation, or dimensional deformation that may occur with traditional cleaning methods, making it particularly suitable for precision mechanical parts with high requirements for surface integrity.

[0003] Currently, fully automatic multi-tank vacuum hydrocarbon cleaning machines exist on the market, such as the fully automatic vacuum hydrocarbon cleaning machine disclosed in prior art CN201620533914.9, the multi-tank alloy stamping parts vacuum hydrocarbon cleaning and drying machine disclosed in prior art CN201911371203.0, and the three-station vacuum ultrasonic hydrocarbon solvent fully automatic cleaning machine disclosed in prior art CN202010759159.7. These machines can automate and continuously operate multiple processes such as cleaning, rinsing, and drying, thus improving production efficiency. However, the typical design of these machines usually relies on cleaning frames (or cleaning baskets) to hold and transfer the workpieces to be cleaned. This design has a significant bottleneck in actual operation: a large number of workpieces are densely stacked in the cleaning frame. Although some machines integrate agitation mechanisms in the cleaning tank, aiming to agitate the cleaning fluid and enhance its contact and scouring force with the workpiece surface by causing the cleaning frame and workpiece to generate periodic movements (such as up and down throwing), thereby improving the cleaning effect. However, due to the rigid structure of the cleaning frame itself and the tight packing of the workpieces inside, the energy generated by the agitation is difficult to be fully and evenly transferred to the surface of each workpiece enclosed inside. The contact points between workpieces and between workpieces and the frame wall create obstacles, severely restricting the free flow of liquid and effective rinsing. Therefore, the agitation mechanism in existing technologies has a limited range of action, and its cleaning effect is not significantly improved for the interior of complex-shaped workpieces, deep holes, blind holes, or tightly packed areas. It is also difficult to completely solve the problem of cleaning dead zones caused by workpiece packing, thus limiting further improvements in overall cleaning efficiency and cleanliness.

[0013] Preferably, the conveying unit includes two horizontally arranged and parallel guide rails on the top of the frame, a conveying base slidably arranged on the two guide rails, a translation drive assembly for driving the conveying base to move horizontally, a rotation drive assembly arranged below the conveying base for driving the roller to rotate, and a lifting drive assembly arranged vertically on the conveying base for driving the rotation drive assembly to move up and down.

[0014] Preferably, the rotary drive assembly includes a rotary mounting base, gear drive modules respectively disposed at both ends of the rotary mounting base, and opening / closing cylinders respectively disposed at both ends of the rotary mounting base for driving the two gear drive modules closer or further apart.

[0015] The gear drive module includes a vertically placed movable side plate, a rotary drive gear rotatably disposed on the lower inner side of the movable side plate and capable of meshing with the tooth groove on the drive ring, a rotary drive motor disposed on the upper inner side of the movable side plate, and a chain drive disposed on the outer side of the movable side plate for connecting the drive shaft of the rotary drive motor and the shaft of the rotary drive gear; the movable side plate is connected to the drive end of the opening and closing cylinder.

[0016] Preferably, the opening and closing cylinder is a twin-shaft cylinder.

[0017] Preferably, the transport base is provided with clearance holes;

[0019] Preferably, a guide rail assembly is provided between each of the lifting drive racks and the lifting mounting base; the guide rail assembly includes at least two sliders that are vertically arranged on the lifting mounting base and spaced apart vertically, and a vertically arranged slide rail that is slidably connected to the sliders.

[0020] The slide rail is connected to the lifting drive rack via a reinforcing column;

[0022] Preferably, the translation drive assembly includes a crossbeam located on one side of the guide rail, a translation drive rack horizontally arranged on the crossbeam, a translation drive motor arranged on the transport base and placed perpendicular to the translation drive rack, and a translation drive gear sleeved on the drive shaft of the translation drive motor and meshing with the translation drive rack.

[0025] By employing the above-mentioned technical solution, this utility model achieves a significant improvement in technical performance by replacing the traditional fixed cleaning frame with a rotatable roller and combining it with the core design of driving the roller to rotate during the transfer process using a transport unit.

[0026] 1. Dynamic tumbling, completely eliminating dead corners: The continuous or intermittent rotation of the roller during the transfer process drives the internal workpieces to dynamically tumble and rearrange. This fundamentally breaks the problem of mutual obstruction and contact point obstruction caused by the static accumulation of workpieces in traditional cleaning frames, allowing all surfaces (including cavities and gaps) of workpieces (especially those with complex shapes, deep holes / blind holes, or easy stacking) to be fully and evenly exposed to the cleaning fluid and vacuum environment, completely eliminating cleaning dead corners;

[0027] 2. Enhanced contact significantly improves cleaning and drying efficiency:

[0028] Cleaning stage (ultrasonic degassing, ultrasonic vacuum): The dynamic tumbling of the workpiece significantly increases the contact frequency and area between its surface and the fresh hydrocarbon cleaning solution. Combined with the cavitation effect of ultrasound and the enhanced liquid permeability of the vacuum environment, stubborn oil stains, microparticles and impurities can be more efficiently peeled off and removed, resulting in a significant improvement in cleaning cleanliness.

[0029] Drying stage (vacuum drying): Rotation helps to remove and disperse residual droplets on the workpiece surface. In a vacuum environment, it can accelerate the evaporation and removal of solvent, achieving a faster and more thorough drying effect and avoiding secondary pollution.

[0030] 3. Improved process efficiency and consistency: Because each workpiece receives ample dynamic processing within the drum, the cleaning and drying effects on all workpieces within a batch are more uniform, reducing rework or defect rates caused by uneven cleaning. Simultaneously, the more efficient cleaning and drying process itself helps shorten the overall process cycle. Attached Figure Description

Distillation recovery system. Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0041] Appendix Figure 1-2 The fully automatic multi-tank vacuum hydrocarbon cleaning machine of this utility model includes a frame 1, multiple rollers 2 for storing the work to be cleaned, a feeding unit 3, an ultrasonic degassing cleaning unit 4, an ultrasonic vacuum cleaning unit 5, two vacuum drying units 6, a discharging unit 7, a conveying unit 8, a vacuum unit, and a distillation recovery system 9, all of which are respectively set on the frame 1.

[0042] The feeding unit 3, ultrasonic degassing and cleaning unit 4, ultrasonic vacuum cleaning unit 5, two vacuum drying units 6, and unloading unit 7 are arranged side by side in a straight line.

[0043] The conveying unit 8 is horizontally located at the top of the frame 1 and is used to transfer the roller 2 between the feeding unit 3, the ultrasonic degassing and cleaning unit 4, the ultrasonic vacuum cleaning unit 5, the two vacuum drying units 6, and the unloading unit 7, and can drive the roller 2 to rotate during the transfer process.

[0044] The vacuum unit is used to evacuate the ultrasonic degassing and cleaning unit 4, the ultrasonic vacuum cleaning unit 5, the vacuum drying unit 6, and the distillation recovery system 9.

[0045] The distillation recovery system 9 is used to generate steam by heating and boiling under vacuum, to distill and regenerate the cleaning liquid, and to separate it from the oil.

[0046] During operation: Manual or automated equipment places the roller 2 containing the workpieces to be cleaned onto the loading unit 3, then starts the equipment. The loading unit 3 moves the roller 2 to the material handling unit 8, where it is then moved from the loading unit 3 to the ultrasonic degassing and cleaning unit 4 for coarse cleaning. After coarse cleaning, the loading unit 8 moves the roller from the ultrasonic degassing and cleaning unit 4 to the ultrasonic vacuum cleaning unit 5 for fine cleaning. During the transfer process, the loading unit 8 drives the roller 2 to rotate continuously or intermittently, causing the internal workpieces to tumble and rearrange dynamically, which greatly increases the contact frequency and contact area between the surface and the fresh hydrocarbon cleaning solution. After fine cleaning, the loading unit 8 sequentially sends the roller from the ultrasonic vacuum cleaning unit 5 to two vacuum drying units 6 for drying, and finally places it on the unloading unit 7. After cooling, the roller is removed and output through the unloading unit 7.

[0047] Furthermore, such as Figure 3 As shown, the roller 2 includes a hollow circular basket 21 for storing the work to be cleaned, and drive rings 22 respectively disposed at both ends of the circular basket 21 and placed coaxially; the surface of the circular basket 21 is provided with through holes to facilitate the entry of cleaning fluid into the circular basket 21; the drive ring 22 is provided with a ring of evenly spaced circumferential grooves 23.

[0048] like Figure 4-5 As shown, the conveying unit 8 includes two horizontally arranged and parallel guide rails 81 on the top of the frame 1, a conveying base 82 slidably arranged on the two guide rails 81, a translation drive assembly 83 for driving the conveying base 82 to move horizontally, a rotation drive assembly 84 arranged below the conveying base 82 for driving the roller 2 to rotate, and a lifting drive assembly 85 vertically arranged on the conveying base 82 for driving the rotation drive assembly 84 to move up and down.

[0049] like Figure 5 As shown, the rotary drive assembly 84 includes a rotary mounting base 841, gear drive modules 842 respectively disposed at both ends of the rotary mounting base 841, and opening and closing cylinders 843 respectively disposed at both ends of the rotary mounting base 841 for driving the two gear drive modules 842 to move closer or further away.

[0050] like Figure 5-6As shown, the gear drive module 842 includes a vertically placed movable side plate 8421, a rotary drive gear 8422 rotatably disposed on the lower inner side of the movable side plate 8421 and capable of meshing with the tooth groove 23 on the drive ring 22, a rotary drive motor 8423 disposed on the upper inner side of the movable side plate 8421, and a chain drive 8424 disposed on the outer side of the movable side plate 8421 for connecting the drive shaft of the rotary drive motor 8423 and the rotating shaft of the rotary drive gear 8422; the movable side plate 8421 is connected to the drive end of the opening and closing cylinder 843.

[0051] During material handling: The two gear drive modules 842 are driven away from each other by the two opening and closing cylinders 843, so that the distance between the two rotating drive gears 8422 is greater than the length of the drum 2. Then, with the joint assistance of the translation drive assembly 83 and the lifting drive assembly 85, the two rotating drive gears 8422 driving the rotating drive assembly 84 are located at the middle of both ends of the drum 2. Next, the two opening and closing cylinders 843 drive the two gear drive modules 842 to move closer to each other until the two rotating drive gears 8422 are located in the drive rings 22 at both ends of the circular basket 21. Finally, the lifting drive assembly 85 drives the rotating drive assembly 84 to rise. During the rising process, the two rotating drive gears 8422 mesh with the tooth grooves 23 on the drive ring 22, thereby driving the drum 2 to rise synchronously. The material feeding process is the reverse of the material handling process, so it will not be described in detail.

[0052] When it is necessary to drive the drum 2 to rotate: the rotary drive motor 8423 drives the rotary drive gear 8422 to rotate through the chain drive 8424. Since the rotary drive gear 8422 meshes with the tooth groove 23 on the drive ring 22, it drives the round basket 21 to rotate synchronously.

[0053] Furthermore, the opening and closing cylinder 843 is a dual-shaft cylinder, which makes the translation of the drive gear drive module 842 more stable.

[0054] Furthermore, the transport base 82 is provided with clearance holes;

[0055] like Figure 5 As shown, the lifting drive assembly 85 includes a lifting mounting base 851 vertically mounted on the transport base 82, two lifting drive racks 852 vertically slidably mounted on the lifting mounting base 851 and passing through clearance holes, a lifting drive shaft 853 horizontally and rotatably mounted on the lifting mounting base 851, a lifting drive motor 854 mounted on the lifting mounting base 851 for driving the lifting drive shaft 853, and two lifting drive gears 855 sleeved on the lifting drive shaft 853 and respectively meshing with the two lifting drive racks 852;

[0056] During lifting: The lifting drive motor 854 drives the lifting drive shaft 853 to rotate the two lifting drive gears 855. Since the two lifting drive gears 855 mesh with the two lifting drive racks 852 respectively, the two lifting drive racks 852 are driven to lift. This utility model uses two lifting drive racks 852, which makes the lifting of the rotating drive component 84 more stable and less prone to shaking.

[0057] Furthermore, such as Figure 5 As shown, each of the lifting drive racks 852 is provided with a guide rail assembly between it and the lifting mounting base 851; the guide rail assembly includes at least two sliders that are vertically arranged on the lifting mounting base 851 and spaced apart vertically, and a vertically arranged slide rail 856 that is slidably connected to the sliders.

[0058] The slide rail 856 is connected to the lifting drive rack 852 via a reinforcing column 857;

[0059] The rotating mounting base 841 is fixedly connected to the bottom of the reinforcing column 857;

[0060] This invention greatly increases strength by setting a reinforcing column 857 between the slide rail 856 and the lifting drive rack 852, making the slide rail 856 and the lifting drive rack 852 less prone to deformation and increasing their service life.

[0061] Furthermore, the reinforcing column 857 is made of aluminum profile, which is a standard existing part and can be directly processed for installation, resulting in low cost.

[0062] Furthermore, such as Figure 4-5 As shown, the translation drive assembly 83 includes a crossbeam 831 located on one side of the guide rail 81, a translation drive rack 832 horizontally arranged on the crossbeam 831, a translation drive motor 833 arranged on the transport base 82 and placed perpendicular to the translation drive rack 832, and a translation drive gear 834 sleeved on the drive shaft of the translation drive motor 833 and meshing with the translation drive rack 832.

[0063] During translation: The translation drive motor 833 drives the translation drive gear 834 to rotate. Since the translation drive gear 834 meshes with the translation drive rack 832, the transport base 82 is driven to translate.

[0064] Furthermore, the ultrasonic degassing cleaning unit 4, the ultrasonic vacuum cleaning unit 5, and the vacuum drying unit 6 are all equipped with a slinging device (not shown in the figure) that drives the roller 2 to rotate. During the cleaning process, the workpiece is slinged evenly, which can increase the friction between the surface of the workpiece and the liquid, which is conducive to the rapid removal of surface dirt and improves the cleaning effect. The slinging device is existing technology, such as the slinging device of a hydrocarbon cleaning machine disclosed in application number CN200910209563.0, so its structure will not be described in detail.

[0065] Furthermore, the ultrasonic degassing cleaning unit 4, ultrasonic vacuum cleaning unit 5, and vacuum drying unit 6 are existing technologies, such as the three-station vacuum ultrasonic hydrocarbon solvent fully automatic cleaning machine disclosed in CN202010759159.7, which describes a degassing ultrasonic cleaning tank, a vacuum ultrasonic rinsing tank, and a vacuum steam rinsing and drying tank. Therefore, their structures will not be described in detail.

[0066] Furthermore, such as Figure 7 As shown, the feeding unit 3 and the unloading unit 7 have the same structure, with one half located inside the frame 1 and the other half extending outside the frame 1. They include a material rack 31, two horizontally arranged parallel sliding rods 32 inside the material rack 31, a sliding table 33 slidably arranged on the two sliding rods 32, and a translation cylinder 34 horizontally arranged inside the material rack 31 for driving the sliding table 33; the sliding table 33 is provided with a contour positioning groove.

[0067] Next, let's take the feeding unit 3 as an example: When feeding, the translation cylinder 34 drives the slide table 33 to extend out of the frame 1. The manual or automated equipment will place the roller 2 on the contour positioning groove of the slide table 33. Then, the translation cylinder 34 drives the slide table 33 to retract into the frame 1, and the material is automatically fed through the handling unit 8.

[0068] Furthermore, the vacuum unit includes three vacuum pumps (not shown in the figure), one of which is used to degas the ultrasonic degassing and cleaning unit 4, and the other two are used to evacuate the ultrasonic vacuum cleaning unit 5 and the vacuum drying unit 6 respectively.

[0069] Furthermore, the distillation recovery system 9 is existing technology, such as a three-tank hydrocarbon vacuum cleaner disclosed in prior art 202022495999.5, which describes a distillation recovery system, so its structure will not be described in detail here.

[0070] Furthermore, it also includes two filtration systems (not shown in the figure), one of which is used to circulate and filter particulate impurities in the cleaning liquid of ultrasonic degassing cleaning unit 4 and ultrasonic vacuum cleaning unit 5, and the other is used to filter particulate impurities in the cleaning liquid before distillation and regeneration of the distillation recovery system.

[0071] Furthermore, it also includes a discharge cooling unit (not shown in the figure), which is set in front of the discharge port of the discharge unit 7 to accelerate the cooling of the roller 2.

[0072] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
