Description

Technical Field

[0001] The present invention belongs to the technical field of lubrication management of various mechanical equipment in sewage treatment plants, and in particular relates to a fully automatic intelligent refueling system for sewage treatment equipment. Background Art

[0002] Wastewater treatment facilities and equipment must operate continuously around the clock to ensure the quality and quantity of treated water. If equipment malfunctions or requires frequent maintenance due to improper lubrication, this not only increases repair costs but can also disrupt the entire treatment process, impacting the overall effectiveness of wastewater treatment and even causing environmental problems. Therefore, it is crucial to ensure that equipment is automatically refueled and maintains stable operation through a fully automated intelligent refueling system.

[0003] The lubrication requirements of sewage treatment equipment vary due to changes in workload and environmental conditions. For example, in humid environments, a water-resistant lubricant is required, while in high-wear areas, a high-viscosity or high-temperature-resistant lubricant is required. Lubrication maintenance relies on the operator's experience and expertise, and problems such as improper lubricant selection or mixing different types of lubricants can easily occur. This can lead to a decrease in the equipment's lubrication effectiveness, and in severe cases, even damage to the equipment. In addition, manual lubrication operations make it difficult to adjust lubrication strategies in real time to adapt to these complex requirements. Traditional manual lubrication methods often lack effective monitoring methods and cannot perceive the equipment's lubrication status in real time. Over- or under-lubrication of equipment can cause problems: insufficient lubrication increases component wear, while excessive lubrication can waste lubricant and even contaminate the equipment.

[0004] More importantly, manual refueling operations usually require operators to carry equipment and climb to the height of the machine to perform the operation, which not only increases the labor intensity, but also brings many difficulties and potential risks due to the particularity of the working environment. For example, high-altitude operations require operators to maintain balance on narrow, wet, or even slippery surfaces. The slightest carelessness may cause falls or other accidental injuries. In addition, in some scenarios with harsh operating environments, such as areas with high humidity, corrosive gases, or strong vibrations, the difficulty of manual operation is further exacerbated, and operational efficiency and accuracy are difficult to guarantee. This mode of operation not only requires high skills from the operator, but also places more stringent requirements on safety protection equipment, increasing the management and operational burden of the enterprise.

[0005] Furthermore, the operation of sewage treatment plants is directly linked to environmental protection. Therefore, equipment maintenance must not only ensure operational efficiency but also minimize secondary environmental pollution, such as lubricant leaks. The closed and precise nature of the automatic oiling system significantly reduces the risk of lubricant waste and leaks, further aligning with the concept of green sewage treatment plant operations.

[0006] To this end, we provide a fully automatic intelligent refueling system for sewage treatment equipment, which provides comprehensive technical support for the efficient operation and maintenance of the equipment. Summary of the Invention

[0035] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] Example

[0037] See also Figure 1-2The present invention is a fully automatic intelligent refueling system for sewage treatment equipment, comprising: an electric grease pump 1 for extracting and providing high-pressure thrust to convey grease from a grease storage tank; a diverter 2 for distributing the grease from the electric grease pump 1 to a plurality of specific lubrication branch pipelines 3 according to preset requirements; a progressive distributor 4, arranged in each of the lubrication branch pipelines 3, for accurately distributing the grease to each lubrication point according to preset requirements; a pressure transmitter 5, for real-time monitoring and transmitting the pressure state of the grease during the conveying process to the PLC control cabinet 6; a high-pressure electric ball valve 7, for responding to the instructions of the PLC control cabinet 6 to control the flow of grease to the lubrication branch pipeline 3 of a specific device; the PLC control cabinet 6 is used to perform logic control, operation monitoring and abnormal alarm, and realize the control of the entire fully automatic intelligent refueling system through a preset program;

[0038] The fully automatic intelligent refueling system adds grease to the coarse grid 8, fine grid 9, fine grid 10 or various refueling points of other equipment in the sewage treatment process on time, in quantity and evenly according to the set lubrication plan;

[0039] Specifically, the fully automatic intelligent refueling system is started and stopped by commands sent by the PLC control cabinet 6 in the system. As the core control unit of the system, the PLC control cabinet 6 realizes the logical control, operation monitoring and abnormal alarm of the entire system through preset programs, ensuring that the grease supply is synchronized with the equipment demand. The user sets the lubrication plan through the PLC control cabinet 6, including the refueling time, frequency and oil supply amount. The system controls the start and stop of the electric grease pump 1 and the high-pressure electric ball valve 7 according to the set logical sequence to complete the lubrication process. The electric grease pump 1 is responsible for extracting grease from the grease storage tank and providing high-pressure thrust to transport the grease to the main delivery pipeline of the system. The main delivery pipeline uses high-strength copper pipes or stainless steel pipes, which can withstand a certain pressure and ensure that the grease remains stable during the delivery process;

[0040] After the grease is delivered from the electric grease pump 1 to the diverter 2, the diverter 2 distributes the grease to specific lubrication branch lines 3 according to the equipment's refueling requirements to meet the needs of multiple devices or multiple lubrication points. In each lubrication branch line 3, the progressive distributor 4 distributes the grease according to the preset demand of the lubrication point, further accurately distributing the grease to the specific lubrication point of the equipment, ensuring that each refueling point receives the required amount of grease. The high-pressure electric ball valve 7 is used to control the flow of grease to the lubrication branch line 3 of a specific device. The switching operation is realized according to the instructions of the PLC. According to the logic of the lubrication process, the high-pressure electric ball valve 7 opens or closes in sequence to ensure that the grease is supplied to each device in sequence.

[0041] At the same time, the PLC control cabinet 6 collects real-time data from the pressure transmitter 5, monitors the grease pressure and handles abnormal conditions. The pressure transmitter 5 monitors the pressure status of the grease in the delivery pipeline in real time to ensure stable grease delivery. The pressure transmitter 5 transmits the pressure data to the PLC control cabinet 6 in real time to display the current pressure status. If the pressure is too low (such as a pipeline rupture or leakage), the system automatically stops the pump and alarms. If the pressure is too high (such as a pipeline blockage), the system will issue an alarm to prevent equipment damage.

[0042] Further settings for the fully automatic intelligent refueling system include:

[0043] The fully automatic intelligent refueling system also includes a grease status monitoring module 11 for real-time detection of the quality status of the grease. The grease status monitoring module 11 is located after the progressive distributor 4 and before the specific lubrication points of each device. The grease status monitoring module 11 is connected to the PLC control cabinet 6. The grease status monitoring module 11 detects the quality status of the grease in real time, including viscosity, particle contamination, and moisture content, to ensure the stability of the grease quality during use, avoid equipment wear due to grease aging or contamination, and provide grease replacement reminders to further reduce unnecessary waste.

[0044] The fully automatic intelligent refueling system also includes a sensor module 12. The temperature sensor and vibration sensor in the sensor module 12 are distributed at key parts of the equipment. The sensor module 12 is connected to the PLC control cabinet 6 in combination with the algorithm model. The temperature sensor and the vibration sensor monitor the operating temperature and vibration conditions respectively, and are linked with the PLC control cabinet 6. The PLC control cabinet 6 can dynamically adjust the lubrication amount according to the temperature and vibration status of the equipment to achieve precise lubrication. By monitoring the abnormal vibration of the equipment, possible faults such as insufficient lubrication or wear of equipment components can be warned in advance.

[0045] The fully automatic intelligent refueling system is equipped with an automatic cleaning subsystem 13, which acts on the lubrication branch pipeline 3 and the progressive distributor 4. The automatic cleaning subsystem 13 is connected to the PLC control cabinet 6, and the external cleaning agent storage tank is connected to the automatic cleaning subsystem 13. The delivery pipeline and distributor are cleaned regularly to prevent the accumulation of pollutants or agglomeration of grease after long-term operation, thereby ensuring the delivery efficiency and cleanliness of the grease, extending the service life of the system, and reducing the frequency of manual cleaning and maintenance costs.

[0046] The fully automatic intelligent refueling system is integrated with an uninterruptible power supply module 14. The uninterruptible power supply module 14 is located near the PLC control cabinet 6 and is integrated into the power supply circuit of the fully automatic intelligent refueling system. The uninterruptible power supply module 14 is connected to the mains power supply to ensure the normal operation of the system in the event of a sudden power outage, ensuring that key equipment can complete the lubrication process in the event of a power outage, avoiding equipment damage caused by lubrication interruption, and improving the reliability and emergency response capabilities of the system.

[0047] The fully automatic intelligent refueling system is equipped with an automatic grease replacement subsystem 15. The automatic grease replacement subsystem 15 is established in the delivery pipeline between each grease storage tank and the electric grease pump 1. The automatic grease replacement subsystem 15 is also connected to the PLC control cabinet 6. It supports switching between multiple grease types to meet the lubrication requirements of different equipment. It can automatically select the appropriate grease type according to the equipment type and working conditions, thereby improving the flexibility and versatility of the system.

[0048] The fully automatic intelligent refueling system has a monitoring subsystem 16 for visualizing the lubrication process. The monitoring subsystem 16 includes high-definition cameras or infrared detection devices distributed at the coarse grid 8, fine grid 9, fine grid 10 or various key refueling points of other equipment. The high-definition cameras or infrared detection devices monitor the lubrication process in real time and transmit the images to the control terminal, providing real-time visualization of the lubrication status, making it easier for operators to monitor key lubrication points and serving as an auxiliary tool for maintenance and troubleshooting.

[0049] The fully automatic intelligent refueling system is provided with an environmentally friendly grease recovery subsystem 17, which is integrated with the grease delivery network and is equipped with an independent storage tank. The environmentally friendly grease recovery subsystem 17 is used to recover excess or waste grease for processing, thereby reducing grease waste and lowering the risk of environmental pollution. After recovery, the grease can be reused or treated in an environmentally friendly manner, meeting the requirements of sustainable development.

[0050] In summary, a fully automatic intelligent refueling system for sewage treatment equipment is applied to the lubrication management of various mechanical equipment in sewage treatment plants.

[0051] Application Examples

[0052] The coarse screen 8, fine screen 9, and fine screen 10 equipment operating in the pretreatment unit of a municipal sewage treatment plant are core components of wastewater filtration. The high-frequency, high-load operation of these equipment places higher demands on lubrication management. The plant utilizes a fully automatic intelligent lubrication system, incorporating several innovative features, to comprehensively enhance the intelligence, reliability, and environmental performance of equipment lubrication management.

[0053] The system uses the PLC control cabinet 6 and intelligent lubrication management software to set the equipment's lubrication plan, and combines AI algorithms to analyze equipment operating data to optimize lubrication frequency and oil supply:

[0054] Each maintenance of the coarse grid requires 50g of grease and the operating time is 50 minutes;

[0055] Each maintenance of the fine grid requires 30g of grease and 30 minutes of operation;

[0056] Each maintenance of the fine grid requires 40g of grease and the operating time is 40 minutes.

[0057] At dawn on the 15th of each month, the PLC control system initiates the lubrication task according to a pre-set schedule. Electric grease pump 1 begins operation, pumping grease from the storage tank to the piping system. Based on the equipment's operating conditions, the system automatically switches to the appropriate grease type for the current operating conditions, supporting multiple grease types to accommodate diverse equipment needs. During the grease delivery process, the system monitors the grease's viscosity, particle contamination, and moisture content in real time. If the grease quality falls below standard, the system issues an alarm and prompts a grease replacement. In the event of a sudden power outage, the UPS module ensures normal system operation and completes the lubrication task.

[0058] The lubrication process is monitored in real time by high-definition cameras installed at key nodes of the pipeline, and the images are transmitted to the control end, so that the operator can check the grease delivery status at any time. Through the software platform, managers can remotely view lubrication operation data (such as pressure, flow and grease residue) on mobile devices, and can adjust operating parameters or terminate lubrication tasks. The system combines AI algorithms to predict the lubrication needs of the next cycle and optimize the lubrication plan. After the lubrication task is completed, the system starts the cleaning program to remove residual grease and contaminants in the pipeline and distributor, maintain the cleanliness of the system, and extend the service life of the equipment. Excess grease is recycled to a dedicated storage module, sorted and reused after processing, avoiding waste and reducing the risk of environmental pollution.

[0059] Wireless communication modules are used to achieve unified management and regional control of multiple lubrication systems in the factory. Pressure transmitters monitor the pressure in the pipeline. If the pressure is abnormal (such as too high or zero), the system will immediately alarm and suspend operation. The lubrication management software records abnormal data and provides troubleshooting suggestions to help quickly restore normal equipment operation. The lubrication data of each device is uploaded to the cloud in real time. The system automatically stores the operating data of all lubrication tasks, including operating time, grease consumption, fault records, etc. Managers can remotely control multiple lubrication systems to achieve unified management across regions and reduce wiring complexity and maintenance costs.
