Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning equipment, and in particular to an ultrasonic cleaning fluid circulation and purification device for bearing parts. Background Technology

[0002] As a core component in mechanical systems that enables rotational or linear motion, bearings directly impact the overall performance of the machine through their operational accuracy and lifespan. During long-term service, a mixture of contaminants, including engine oil, metal shavings, and dust, easily accumulates on the bearing surface. Engine oil, in particular, is prone to polymerization and condensation under high-temperature oxidation or low-temperature conditions, forming a viscous sludge that adheres to the bearing raceways and cage clearances. This leads to increased friction, lubrication failure, and in severe cases, abnormal wear or even seizure. Therefore, efficiently removing the condensed oil film from the bearing surface is crucial for ensuring its performance.

[0003] In existing bearing cleaning technologies, ultrasonic cleaning equipment achieves deep cleaning through cavitation. It uses high-frequency vibration to create micro-jet shock waves in the cleaning fluid, effectively removing stubborn dirt from complex surfaces. Water-based cleaning solvents, due to their low toxicity and biodegradability, are gradually replacing traditional organic solvents as the mainstream cleaning medium. However, conventional ultrasonic cleaning equipment faces significant technical bottlenecks. During the cleaning process, the cleaning fluid containing dissolved oil is directly discharged as waste, requiring frequent replenishment of the solvent to maintain cleaning capacity. Taking industrial bearing cleaning as an example, a single production line can consume hundreds of liters of cleaning agent daily, not only wasting resources but also creating difficulties in handling high concentrations of COD, surfactants, and heavy metal residues in the waste fluid. Currently, the industry commonly uses neutralization precipitation and biochemical treatment processes, but problems such as difficulty in foam control and salinity inhibiting microbial activity lead to high treatment costs and pose a risk of secondary pollution. Utility Model Content

[0004] To overcome the drawbacks of resource waste, this utility model provides an ultrasonic cleaning fluid circulation and purification device for bearing parts, aiming to solve the above-mentioned shortcomings.

[0005] An ultrasonic cleaning fluid circulation and purification device for bearing parts includes a cleaning tank and a connecting plate. A controller is installed on the front side of the cleaning tank. A collection tank is slidably connected to the bottom of the cleaning tank. A vibrating frame is slidably connected inside the cleaning tank. Several guide rods are connected to the rear side of the vibrating frame. The guide rods are slidably connected to the rear side plate of the cleaning tank. A first return spring is sleeved on the guide rod and is located between the vibrating frame and the cleaning tank. A squeezing rod is rotatably connected inside the cleaning tank. The squeezing rod is in a squeezing fit with the front side of the vibrating frame. A motor is installed on the side of the cleaning tank. The rotating shaft of the squeezing rod passes through the cleaning tank and is connected to the output shaft of the motor. The motor is wired to the controller. The connecting plate is slidably connected inside the cleaning tank and a filter screen is connected to the connecting plate.

[0006] Optionally, the vibrating frame has mating grooves on the left and right sides at the bottom, the connecting plate has a plug rod connected to the bottom, the extrusion plate is slidably connected in the mating groove, a second return spring is provided between the extrusion plate and the vibrating frame, one end of the second return spring is connected to the extrusion plate and the other end is connected to the vibrating frame, the plug rod is slidably connected to the two extrusion plates, the filter frame has mating grooves in the middle of the left and right ends of the connecting plate, the multiple layers of the connecting plate are mated together, and the bottom of the plug rod has inclined surfaces on the front and back sides.

[0007] Optionally, an activated carbon filter cotton is connected to the bottom of the shaking frame.

[0008] Optionally, the bottom of the cleaning tank is equipped with several stabilizing feet.

[0010] Optionally, a flow guide is connected to the top of the cleaning tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By sliding the multi-layer filter frame and the shaking frame, filter screens of different mesh sizes and materials are arranged in a gradient of coarseness, thereby achieving graded filtration of the cleaning solution, extending the service life of the cleaning solution, and reducing the consumption of cleaning agent.

[0013] 2. By engaging the squeezing rod with the cam of the vibrating frame, the motor drives the squeezing rod to rotate, causing the vibrating frame to reciprocate. This generates micro-turbulence in the liquid inside the filter screen, accelerating the settling of unadsorbed particles and reducing filter screen clogging, thereby improving filtration efficiency and reducing the frequency of filter component replacement.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] Example: An ultrasonic cleaning fluid circulation and purification device for bearing parts, such as... Figures 1-4 As shown, the system includes a cleaning tank 1, a controller 2, a collection tank 3, a shaking frame 4, guide rods 5, a first return spring 6, a squeezing rod 7, a motor 8, a filter frame 9, and a connecting plate 10. The controller 2 is installed on the front side of the cleaning tank 1. The collection tank 3 is slidably connected to the bottom of the cleaning tank 1. The shaking frame 4 is slidably connected inside the cleaning tank 1, with gaps maintained between the shaking frame 4 and the inner wall of the cleaning tank 1. Several guide rods 5 are connected to the rear side of the shaking frame 4, and the guide rods 5 are slidably connected to the rear plate of the cleaning tank 1. The first return spring 6 is sleeved on the guide rod 5 and is located on the shaking frame 4. Between the cleaning tank 1 and the washing tank 1, a squeezing rod 7 is rotatably connected inside the washing tank 1. The squeezing rod 7 is squeezed and engaged with the front side of the shaking frame 4. A motor 8 is installed on the side of the washing tank 1. The rotating shaft of the squeezing rod 7 passes through the washing tank 1 and is connected to the output shaft of the motor 8. The motor 8 is wired to the controller 2. The controller 2, as the electrical control core, can accurately regulate the speed and vibration frequency of the motor 8. The connecting plate 10 is slidably connected inside the washing tank 1. A filter screen frame 9 is connected to the connecting plate 10. Each layer of the filter screen frame 9 has a different mesh size. The upper coarse filter screen intercepts large particulate pollutants, and the lower fine filter screen adsorbs tiny oil droplets.

[0021] like Figure 4As shown, it also includes a rod 11, a pressing plate 12, and a second return spring 13. The bottom left and right sides of the shaking frame 4 have mating grooves. The bottom of the connecting plate 10 is connected to the rod 11. The pressing plate 12 is slidably connected in the mating groove. The second return spring 13 is provided between the pressing plate 12 and the shaking frame 4. One end of the second return spring 13 is connected to the pressing plate 12, and the other end is connected to the shaking frame 4. The rod 11 is slidably connected to the two pressing plates 12. The filter frame 9 and the middle of the left and right ends of the connecting plate 10 have mating grooves. The multi-layer connecting plate 10 is mated vertically. The bottom of the rod 11 is provided with inclined surfaces on the front and back sides.

[0022] like Figure 2 and Figure 3 As shown, it also includes activated carbon filter cotton 14, and the bottom of the shaking frame 4 is connected to activated carbon filter cotton 14.

[0023] like Figure 1 As shown, it also includes stabilizing feet 15. Several stabilizing feet 15 are installed at the bottom of the cleaning tank 1. The stabilizing feet 15 are equipped with rubber shock-absorbing pads to reduce operating noise.

[0024] like Figure 1 As shown, it also includes an observation window 16, and the front side panel of the collection box 3 is provided with an observation window 16 made of transparent material.

[0025] like Figure 1 As shown, it also includes a flow guide 17. The top of the cleaning tank 1 is connected to the flow guide 17. The bottom opening width of the flow guide 17 is slightly smaller than the width of the shaking frame 4 to ensure that all liquid flows in.

[0026] The staff slowly pours the used cleaning solution into the cleaning tank 1 along the guide shroud 17. The bottom opening of the guide shroud 17 is slightly narrower than the width of the shaking frame 4, guiding the liquid to flow in concentratedly through a narrowing design. The multi-layer filter rack 9 is arranged in a gradient of mesh size. The upper coarse filter first intercepts large particulate contaminants such as bearing debris, while the lower fine filter is covered with an oleophilic adsorption coating, which can efficiently trap tiny oil droplets and suspended particles. Different filter materials achieve graded filtration based on the different aggregation states of oil stains. As the cleaning solution is continuously poured in, the staff observes the liquid level in the collection tank 3 in real time through the transparent observation window 16. When the liquid level approaches the safety threshold, pouring is stopped to prevent liquid overflow.

[0027] After the filtration stage starts, the controller 2 drives the motor 8 to rotate the squeezing rod 7. As a cam mechanism, the squeezing rod 7 periodically pushes the front plate of the vibrating frame 4, forcing the vibrating frame 4 to slide backward along the guide rod 5 and compress the first return spring 6. When the large-diameter section of the squeezing rod 7 passes the contact point, the first return spring 6 releases its elastic potential energy, pushing the vibrating frame 4 back to its original position, forming a high-frequency reciprocating vibration. This vibration causes micro-turbulence in the liquid within the filter frame 9, accelerating the settling of unadsorbed particles and reducing the risk of filter clogging. After filtration, the cleaning liquid, after secondary adsorption by the activated carbon filter cotton 14, flows into the collection tank 3. The operator holds the handle of the collection tank 3 and pushes it back to the fixed position at the bottom of the cleaning tank 1, completing the cleaning liquid recovery. A small amount of cleaning solvent is then added to the ultrasonic cleaner to maintain the liquid's cleaning performance.

[0028] If the filtration rate drops significantly, the operator disassembles the flow guide shroud 17, vertically lifts the outer frame of the filter screen frame 9, and the bottom insert rod 11 of the connecting plate 10 presses the two side extrusion plates 12 through the inclined structure, pushing the extrusion plates 12 outward and compressing the second return spring 13. After the insert rod 11 is completely removed, the filter screen frame 9 assembly and activated carbon filter cotton 14 are taken out in sequence. At the same time, the collection box 3 is removed, and the activated carbon filter cotton 14 is removed from the bottom of the shaking frame 4. The contaminated filter media are classified and processed. Metal scraps are cleaned and reused, and oil is recovered as base oil through thermal reduction. Filter media that cannot be regenerated are disposed of harmlessly in accordance with environmental protection requirements. When replacing the filter media, the insert rod 11 is inserted into the gap of the extrusion plate 12 along the original path. The inclined structure pushes the extrusion plate 12 outward, and the spring returns to clamp the insert rod 11, ensuring that the filter screen frame 9 and the shaking frame 4 are sealed and fitted, restoring the filtration function. Finally, the flow guide shroud 17 is installed.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
