Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of cleaning equipment, and specifically to a bearing retainer cleaning control method and control device. Background Art

[0002] Spatial bearings are the core mechanical components of single-unit spatial mechanisms, such as momentum wheels and control torque gyroscopes. Their performance directly impacts the reliability and lifespan of spatial actuators. Bearings generally consist of an inner ring, an outer ring, rolling elements, and a cage. The cage is often made of porous polymer materials. As a key component of the bearing in the momentum wheel shaft system, the cage guides the rotation of the bearing's rolling elements and prevents them from detaching. It also has excellent oil storage, supply, and return properties, enabling self-circulating oil lubrication of the bearing. After milling and other machining processes, foreign matter such as airborne dust can remain and contaminate the cage. Furthermore, the cage's inherent microporous structure can severely affect the cage's surface finish, significantly impacting the bearing's operating accuracy and stability. This can cause abnormal vibration and increased friction torque, impacting the flywheel's operating life. Therefore, the cage requires a cleaning process to ensure its cleanliness.

[0003] Manual cleaning is commonly used in related technologies. During the cleaning process, people use handheld cleaning tools, which often come into direct contact with the bearing cage, adversely affecting the cage's surface quality and mechanical strength. This also requires high cleaning skills and is prone to random damage. Cleaning equipment, such as ultrasonic cleaning, can also cause irreversible damage to the cage's structural strength and surface quality due to high-frequency vibrations.

[0004] In response to the above problems, relevant technologies have not yet proposed effective technical solutions, can no longer meet people's requirements, and are in urgent need of improvement. Summary of the Invention

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0028] From the background technology, it can be seen that the related technologies have defects such as surface damage risk, unstable cleaning quality, low cleaning efficiency, and high-frequency vibration structural damage risk in the process of cleaning bearing retainers, and the manual cleaning speed is slow, which is difficult to meet the needs of large-scale production, and the cleaning equipment of the related technologies is difficult to completely remove the pollutants on the surface of the retainer and in the micropores, resulting in unsatisfactory cleaning effect, affecting the operation accuracy and stability of the bearing. In response to the above technical problems, the embodiments of the present application utilize low-boiling point hydrocarbon solvents such as petroleum ether, and through Soxhlet extractor devices, cooling systems, heating devices, controllers and other equipment, to achieve efficient dissolution and extraction of pollutants on the surface of the retainer and in the micropores, and adopt solid-liquid extraction (leaching) to achieve the cleaning of the bearing retainer, which effectively improves the cleanliness of the retainer and avoids damage to the retainer's own structure and surface quality problems.

[0029] Glossary:

[0030] Solid-liquid extraction, extracting soluble components from solids into liquids.

[0031] Extraction is the process of using a liquid solvent to dissolve and separate specific components from a solid. During this process, the solvent comes into contact with the solid, dissolving the target component in the solvent. The solvent is then separated from the solid matrix by separation means (such as filtration, centrifugation, condensation, etc.). For example, in the embodiments of this application, extraction is used in industrial cleaning to extract pollutants such as oil and dust from solid mechanical parts.

[0032] Extraction refers to the process of extracting or separating specific components from a substance. In some specific cases, extraction can include the meanings of leaching and extraction, but it focuses more on the overall operation of the extraction process. For example, extracting target components from a sample for analysis may include steps such as contact, dissolution, and separation of the solvent and the solid or liquid.

[0033] The above-mentioned extraction, leaching, and extraction all involve the process of extracting or sharing specific components from a substance. They can all be used to extract target components from solids. The main differences between the three are:

[0034] Extraction emphasizes the use of the solubility difference between two immiscible solvents for extraction, usually involving the mixing and separation of the two solvents.

[0035] Extraction focuses more on using liquid solvents to dissolve and separate specific components from solids, usually involving contact and separation of the solvent and solid.

[0036] The concept of extraction is broader and can include the meanings of leaching and extraction, but it focuses more on the overall operation of the extraction process.

[0037] In the specific implementation methods involved in the embodiments of the present application, the above-mentioned extraction, leaching, and extraction can be used interchangeably. The specific term to be selected can refer to the application scenario of the extraction process. For example, "extraction" and "leaching" can be understood as the process of extracting the target component from the solid, while "extraction" (solid-liquid extraction) is more suitable for extraction processes involving two immiscible solvents.

[0038] A Soxhlet extractor is an experimental instrument used to extract soluble components from solid samples. The Soxhlet extractor works based on the principle of solvent reflux and siphoning. Through the repetition of these two processes, the soluble components in the solid sample can be continuously extracted.

[0039] The working principle of the Soxhlet extractor is summarized as follows:

[0040] Solvent heating and vaporization: Add an appropriate amount of solvent (such as petroleum ether, ethanol, etc.) to the extraction bottle (usually a round-bottom flask, etc.), and vaporize the solvent through a heating device (such as a constant temperature water bath). The vaporized solvent rises to the condenser through the connecting tube.

[0041] Condensation reflux: The vaporized solvent is condensed into liquid in the condenser and then drips into the extraction tube. The condensed solvent comes into contact with the solid sample in the extraction tube and dissolves the soluble components in the sample.

[0042] Siphon effect: As the solvent continues to drip into the extraction tube, the liquid level in the extraction tube gradually rises. When the liquid level in the extraction tube reaches the highest point of the siphon tube, the solvent containing soluble components automatically flows into the extraction bottle through the siphon tube.

[0043] Circular extraction: The solvent flowing into the extraction bottle is heated and vaporized again, and the above process is repeated until the soluble components in the solid sample are completely extracted.

[0044] Typical structure of Soxhlet extractor:

[0045] Extraction bottle: used to hold the solvent and vaporize the solvent by heating it through a heating device. An extraction tube is connected to the top of the extraction bottle.

[0046] Extraction tube: located above the extraction bottle, used to place solid samples, where the solvent contacts the sample and extracts it. For example, in the embodiment of the present application, the extraction tube is used to place a bearing retainer.

[0047] Condenser: Connected above the extraction tube, used to condense the vaporized solvent into liquid and return it to the extraction tube.

[0048] Siphon: Located inside the extraction tube, it is used to automatically return the extracted solvent to the extraction bottle.

[0049] The Soxhlet extractor can efficiently extract soluble components from solid samples through the circulation and reflux of solvents, and can significantly reduce the amount of solvent used. It has a high degree of automation, and the extraction process is automatic, without the need for frequent operations. It is suitable for batch processing and is suitable for the extraction of heat-sensitive substances, avoiding damage to the sample caused by high temperature and achieving gentle extraction.

[0050] like Figure 1 The bearing retainer cleaning control method shown includes:

[0051] Step S1, providing a Soxhlet extractor, the Soxhlet extractor comprising an extraction flask, an extraction tube and a condenser, wherein the extraction flask is used to store a hydrocarbon solvent. Preferably, in the embodiment of the present application, the hydrocarbon solvent is petroleum ether.

[0052] Petroleum ether, a hydrocarbon solvent primarily composed of lower alkanes such as pentane and hexane, has excellent solubility and can effectively dissolve organic contaminants such as grease, wax, and resin. During the processing and use of bearing cages, impurities such as oil, dust, and shavings may remain on their surfaces. Petroleum ether can quickly dissolve these organic contaminants, separating them from the cage surface for efficient cleaning.

[0053] Petroleum ether has a low boiling point, between 30-60°C, and is highly volatile. This low boiling point and high volatility allow it to quickly vaporize during the cleaning process. Through the Soxhlet extractor's circulation system, the vaporized petroleum ether condenses into a liquid in the condenser, drips into the extraction tube, and further extracts the cage. This cyclical process of petroleum ether vaporization and liquefaction not only improves cleaning efficiency but also reduces solvent usage and cleaning costs.

[0054] Petroleum ether is a saturated hydrocarbon solvent with mild chemical properties. It will not react chemically with most materials. Therefore, when using petroleum ether as a cleaning solvent to clean the bearing cage, petroleum ether will not damage the surface and structure of the bearing cage, thereby protecting the mechanical strength and surface quality of the bearing cage and avoiding surface scratches or structural damage caused by the cleaning process.

[0055] Bearing cages typically have a multi-microporous structure, which easily retains foreign matter such as dust, seriously affecting the surface finish of the cage. Petroleum ether can penetrate these micropores, dissolving and extracting contaminants within them, ensuring the cleanliness of the bearing cage surface and interior, thereby improving the operating accuracy and stability of the bearing.

[0056] Petroleum ether can be recycled through condensation and siphon reflux during the cleaning process. After the vaporized petroleum ether is condensed into liquid in the condenser, it flows back to the extraction bottle through the siphon tube and continues to be heated and vaporized, forming a continuous circulation process. The circulation process improves the efficiency of solvent use, reduces solvent waste, and reduces cleaning costs.

[0057] Petroleum ether has low volatility and lower toxicity than other solvents, and has less impact on the environment. Therefore, the low volatility of petroleum ether reduces the loss of solvent volatilization during the cleaning process, reducing the harm to operators and the environment.

[0058] In summary, the role of petroleum ether in cleaning bearing cages is mainly reflected in its good solubility, low boiling point and high volatility, mild chemical properties, cleaning ability for multi-microporous structures, recycling, environmental protection and compatibility with automatic control systems. It can clean bearing cages efficiently and gently, ensure the cleanliness of their surface and interior, and improve the operating accuracy and service life of bearings.

[0059] Step S2: Start the cooling system to cool and circulate the cooling water. The cooling system includes a water tank, a water pump, and a chiller. The cooling system is equipped with a water outlet and a water return port. The water tank stores the cooling water, the water pump delivers the cooling water to the Soxhlet extractor, and the water outlet serves as a channel for the condensed water.

[0060] Step S3, starting a heating device, the heating device is used to heat the extraction bottle in the Soxhlet extractor to vaporize the hydrocarbon solvent. Preferably, the heating device is a constant temperature water bath, and the heating device vaporizes the hydrocarbon solvent by heating.

[0061] In step S4, the vaporized hydrocarbon solvent enters the condenser, where it is condensed and liquefied to form a liquid hydrocarbon solvent that drips into the extraction tube. The siphon tube in the extraction tube siphons the liquid hydrocarbon solvent into the extraction flask. The connecting tube serves as a volatilization channel connecting the extraction tube and the condenser. The connecting tube transfers the vaporized hydrocarbon solvent to the condenser, and the siphon tube siphons the petroleum ether liquefied in the condenser into the extraction flask.

[0062] Step S5, extracting the bearing retainer placed in the extraction tube, detecting the heating device in real time, and controlling the cooling system to start or stop according to the current temperature of the heating device until the bearing retainer is cleaned.

[0063] The technical solution provided in steps S1 to S5 provides a method for cleaning a bearing retainer using a Soxhlet extractor and a hydrocarbon solvent. Petroleum ether can be used as a preferred hydrocarbon solvent. The hydrocarbon solvent is recycled through a heating and cooling system, which can efficiently clean the bearing retainer. The cleaning process avoids damage to the retainer surface and structure.

[0064] Steps S1 through S5 achieve porous structure cleaning through solvent recycling: a heating device and cooling system continuously vaporize and condense a hydrocarbon solvent (petroleum ether), dripping it into an extraction tube to extract the bearing cage. Siphoning the solvent back into the cage allows for multiple cleaning cycles, ensuring that contaminants on the bearing cage surface and within its pores are thoroughly removed. The technical solution provided by steps S1 through S5 addresses issues currently encountered in related cleaning processes, such as the limitations of manual cleaning and damage to the cage structure caused by existing cleaning equipment. This not only improves cleaning efficiency and quality, but also protects the cage's mechanical strength and surface quality, extending its service life while achieving environmental and energy-saving benefits.

[0065] In the above embodiment, petroleum ether is used as a cleaning solvent to clean the bearing retainer. In other embodiments, other hydrocarbon solvents may be used to clean the bearing retainer, such as gasoline, kerosene, turpentine, cycloalkanes, n-hexane, cyclohexane, isopropyl alcohol, dichloromethane, ethyl acetate, etc. In other embodiments, the cleaning object is not limited to the bearing retainer, and can be used to clean any object that needs cleaning, for example:

[0066] Provided is a cleaning composition, comprising the following components in parts by mass:

[0067] Degreasing agent: 55-75 parts, hydrocarbon solvent: 8-15 parts, surfactant: 1-10 parts, auxiliary agent: 1-10 parts, diluent: 1-5 parts.

[0068] The degreasing agent is one or more of the following substances: tetrachloroethylene, dichloromethane, and difluorochloroethane.

[0069] The hydrocarbon solvent is one or more of the following substances: gasoline, kerosene, turpentine, cycloalkanes, n-hexane, cyclohexane, isopropyl alcohol, dichloromethane, and ethyl acetate.

[0071] The auxiliary agent is one or more of the following substances: tris(2-hydroxyethyl)amine, di(2-hydroxyethyl)amine, and 2-hydroxyethylamine.

[0072] The above embodiments provide a cleaning composition that can be used to clean industrial products, including bearing retainers. By selecting and mixing different combinations of substances, the cleaning composition achieves efficient dirt removal. In addition to using petroleum ether as the cleaning solvent, a variety of other hydrocarbon solvents, such as gasoline, kerosene, and turpentine, can also be used to meet different cleaning needs and conditions.

[0087] like Figures 2 to 4As shown, the function of the bearing cage cleaning control device is to implement the bearing cage cleaning control method disclosed in any specific embodiment of the present application. The bearing cage cleaning control device includes a controller, a cooling system, a heating device and a Soxhlet extractor. The controller is connected to the cooling system.

[0088] The heating device and cooling system are controlled by a controller. The cooling system includes a refrigerator with a control panel. The heating device heats the extraction flask in the Soxhlet extractor. An extraction tube is located above the extraction flask and connected to the extraction tube via a siphon and a connecting tube. The extraction tube is used to house the bearing retainer and is connected to a condenser above the extraction tube.

[0089] Preferably, the cooling system is connected to multiple Soxhlet extractors, the water outlets of the cooling system are respectively connected to the water inlets of the condensers in the Soxhlet extractors, and the water outlets of the condensers are respectively connected to the water return ports of the cooling system.

[0090] Preferably, a touch screen is provided on the control panel, and the touch screen is used for interaction of control parameters. All control parameters are displayed and controlled on the control panel, and normal operation and fault alarm indicator lights are arranged on the control panel.

[0091] Based on the above-described specific embodiment, the heating device, under operating control mode, can independently heat and cool five extraction systems. Each extraction system can be cleaned independently without interfering with each other. The heating device and cooling water circuit can be started and stopped with a single button via the controller. The start-stop sequence is as follows: Press the start button to activate the cooling system, followed by the heating device 5 minutes later. Press the stop button to deactivate the heating device, followed by the cooling system 30 minutes later. This pre-set start-stop sequence ensures reliable condensation of the extractor's extraction solvent.

[0092] Multiple extraction systems, comprised of bearing cage cleaning control devices, monitor the water temperature of each heating device in real time. If high temperatures are detected, a buzzer sounds and the heating device automatically shuts down. The extraction system also monitors the water tank temperature in real time. If the temperature exceeds a threshold, the cooler automatically activates. If the temperature still exceeds the threshold after the cooler is activated, all heating devices automatically shut down and a buzzer sounds.

[0093] The operating principle of the embodiment of the present application is as follows: During cleaning, the bearing retainer is placed in the extraction tube of a Soxhlet extractor. Petroleum ether is added to the extraction flask. The extraction flask is heated in a constant-temperature water bath to vaporize the petroleum ether, which then rises through a connecting tube into a condenser. The vaporized petroleum ether condenses and liquefies into a liquid that drips into the extraction tube, thereby extracting the retainer. When the petroleum ether level in the extraction tube reaches a certain height, the petroleum ether flows into the extraction flask through a siphon tube. The petroleum ether in the extraction flask continues to be heated, vaporized, rises, condenses, and drips into the extraction tube. This cycle repeats until extraction is complete.

[0094] As can be seen from the above operating principle, during the cleaning process, the bearing cage is placed in the extraction tube of a Soxhlet extractor, and petroleum ether is added to the extraction flask. The extraction flask is then heated in a constant-temperature water bath to vaporize the petroleum ether. The vaporized petroleum ether rises through a connecting tube into a condenser, where it cools and liquefies into a liquid that drips into the extraction tube, thereby extracting the cage. This process not only efficiently dissolves and extracts contaminants from the bearing cage surface and pores, but also significantly improves cleaning efficiency by recycling the petroleum ether. When the petroleum ether level in the extraction tube reaches a certain level, it automatically flows into the extraction flask through a siphon tube, where it continues to be heated and vaporized, rising again, condensing, and dripping into the extraction tube. This continuous cycle ensures that the petroleum ether reaches every corner of the cage, achieving a thorough cleaning effect.

[0095] The bearing cage cleaning control system achieves coordinated cleaning operations through the coordinated use of heating and cooling. Throughout the cleaning process, the heating and cooling systems work together to control the cleaning process. The constant-temperature water bath ensures stable vaporization of petroleum ether within the set temperature range through temperature control, preventing incomplete or excessive vaporization caused by excessively high or low temperatures. Simultaneously, the cooling system monitors the water tank temperature in real time and automatically activates the chiller when the water temperature exceeds 30°C, ensuring that the condenser remains at an optimal low temperature. The coordinated control of temperature and cooling by the heating and cooling systems not only improves the condensation efficiency of petroleum ether, but also extends the equipment's service life and reduces the risk of damage caused by high temperatures or insufficient cooling. Furthermore, the cooling system's five outlet channels, each of which can be individually controlled, further enhance the cooling effect of multiple Soxhlet extractors and improve the flexibility and efficiency of cleaning operations.

[0096] In summary, the bearing cage cleaning control device features a high degree of automation and safety protection. Through the connection of the controller to the cooling system and heating device, all operating parameters can be set and adjusted on the control panel, making it easy to operate and monitor. The touchscreen on the control panel provides an intuitive interface, allowing operators to monitor control parameters such as temperature and cooling water level during the cleaning process in real time, and to control the bearing cage cleaning control device in real time based on changes in these parameters. The bearing cage cleaning control device is also equipped with a real-time alarm system. When abnormal conditions such as overtemperature or cooling water shortage occur, the device automatically triggers an alarm and shuts down, ensuring safe operation. Furthermore, the heating device features protection against dry-burning due to water shortage and high-temperature shutdown, further enhancing the safety and reliability of the device. The automation and safety protection features of the bearing cage cleaning control device not only improve the efficiency and quality of cleaning operations, but also reduce operator workload and equipment operating risks, ensuring that the bearing cage cleaning control device is protected from human damage or vibration during the cleaning process.

[0097] As a specific implementation of the embodiment of the present application, the bearing cage cleaning control device can set the following indicators to achieve the cleaning of the bearing cage:

[0098] Heating device indicators: The heating device is a constant temperature water bath, which has water level warning and temperature monitoring functions. Specific indicators are as follows:

[0099] Temperature control range: room temperature ~ 85℃;

[0100] Temperature control accuracy: ±2℃;

[0101] Protection function: prevent dry burning due to lack of water, and shut down due to high temperature.

[0102] Extractor specifications: cage placement space size: 85*100mm, the number of extraction cages is at least 4.

[0103] Cooling device indicators: The cooling device consists of a water tank, water pump, chiller, water outlet, and water return. The water pump delivers cooling water to the extractor. The outlet pipe has five channels, each of which can be individually controlled. The water tank temperature is monitored in real time. If the temperature exceeds 30°C, the chiller activates. The cooling water level is also monitored in real time. If the cooling water level falls below the minimum, an alarm is triggered and the extractor heating device automatically shuts down.

[0104] Water outlet temperature: ≤30℃;

[0105] Alarm function: with over-temperature alarm, cooling water shortage alarm, and automatic shutdown function after alarm.

[0106] In the above embodiment, the temperature control range of the water bath in the bearing retainer cleaning control device is set to room temperature to 85°C, which meets the temperature conditions required for petroleum ether vaporization. The water bath temperature is controlled with an accuracy of ±2°C, and a temperature sensor and controller ensure the temperature stability of the petroleum ether during the vaporization process.

[0107] The water bath can be equipped with a built-in water level sensor to monitor the water level in real time to prevent dry-boiling. When the water level falls below the set minimum value, the system automatically triggers an alarm and stops heating to prevent dry-boiling and damage to the equipment. When the temperature exceeds the set maximum value, the system automatically shuts down to ensure safe operation.

[0108] The cage space for the extraction tube within the extractor measures 85 mm x 100 mm, accommodating at least four bearing cages to meet batch cleaning requirements. The extraction tube is connected to the extraction flask via a siphon and connecting tube, ensuring smooth circulation of the petroleum ether during vaporization, condensation, and reflux. A condenser is attached above the extraction tube to condense the vaporized petroleum ether into a liquid that drips into the extraction tube to extract the cage.

[0109] The cooling system includes a water tank, a water pump, a chiller, a water outlet and a return water outlet. The water pump transports cooling water from the water tank to the condenser to ensure the low temperature of the condenser. The outlet pipe is a 5-channel pipe that can be controlled individually to meet the cooling needs of multiple extractors. The cooling system monitors the water tank temperature in real time. When the water temperature exceeds 30°C, the chiller automatically starts to ensure that the cooling water temperature does not exceed the set value. The cooling system ensures that the outlet temperature does not exceed 30°C to maintain the efficient operation of the condenser. The cooling system monitors the cooling water level in real time. When the water level is lower than the minimum value, the system triggers an alarm and automatically stops the operation of the heating device to prevent equipment damage due to insufficient cooling water. The cooling system ensures the normal operation of the equipment and the safety of operators through temperature monitoring and over-temperature alarm and cooling water shortage alarm functions.

[0110] Based on the above-mentioned bearing retainer cleaning control device, a bearing retainer cleaning control method in an embodiment of the present application can be implemented, including the following steps:

[0111] Step 1: Start the cooling system: Start the cooling system through the control panel to ensure that the cooling water circulates in the water tank and maintains the low temperature of the condenser.

[0112] Step 2: Start the heating device: Start the heating device through the control panel, set the temperature range of the water bath to room temperature to 85°C, and the temperature control accuracy is ±2°C.

[0113] Step 3: Place the cage: Place the bearing cage into the extraction tube, ensuring that the bearing cage fits tightly against the inner wall of the extraction bottle.

[0114] Step 4: Add petroleum ether: Add an appropriate amount of petroleum ether to the extraction bottle, the amount of petroleum ether added is 1 / 3 to 1 / 2 of the volume of the extraction bottle. In this step, by controlling the amount of petroleum ether, it is ensured that there is enough space for the petroleum ether to vaporize in the extraction bottle.

[0115] Step 5, vaporization and condensation: Heat the extraction bottle to vaporize the petroleum ether. The vaporized petroleum ether rises through the connecting tube into the condenser, condenses and liquefies into liquid and drips into the extraction tube to leaching the retaining frame.

[0116] Step 6, siphon reflux: When the petroleum ether liquid level in the extraction tube reaches a certain height, the petroleum ether flows into the extraction bottle through the siphon tube and continues to be heated and vaporized. The above process is repeated until the extraction is complete.

[0117] Step 7, real-time monitoring and control: monitor the temperature of the heating device, the water temperature of the cooling system, and the cooling water level in real time through the control panel to ensure the stability and safety of the cleaning process.

[0118] Step 8, cleaning completed: After cleaning is completed, stop the heating device and cooling system through the control panel to ensure the safe shutdown of the equipment.

[0119] Through the above technical means and control methods, the bearing retainer cleaning control method can achieve efficient and safe cleaning of the bearing retainer, and at the same time has automation and safety protection functions to ensure the reliability of the operation process.
