[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] This embodiment provides an intelligent lubrication system for a vibrating screen, such as... Figure 1 As shown, the system includes: an oil tank, a heating unit 2, a temperature sensing unit, a filter device 5, a distribution device, a return oil pipe 13, a return oil filter device 6, an oil pump 4, and a control system. The heating unit 2 is located inside the oil tank 1 or is thermally connected to the oil tank 1. The temperature sensing unit is used to monitor the oil temperature at at least one key point in the lubrication circuit. The inlet of the oil pump 4 is connected to the oil tank 1 via a pipeline. The filter device 5 is located on the pipeline between the oil pump 4 and the oil tank 1. The distribution device is used to distribute the filtered lubricating oil to at least one excitation shaft cavity 12 of the vibrating screen 11. One end of the return oil pipe 13 is connected to the excitation shaft cavity 12, and the other end is connected to the inlet of the oil tank 1. The return oil filter device 6 is located at the return oil inlet of the oil tank 1. The control system is signal-connected to the temperature sensing unit, the heating unit 2, and the oil pump 4. This structural configuration constructs a complete lubrication circuit, which can realize the storage, heating, filtering, distribution, return of lubricating oil, and intelligent control of the entire process. Heating unit 2 ensures that the lubricating oil maintains suitable fluidity even at low temperatures, facilitating the start-up of vibrating screen 11; temperature sensing unit monitors oil temperature in real time, providing data support for precise temperature control; filtration device 5 effectively removes impurities from the lubricating oil, extending the service life of the equipment; distribution device ensures that each excitation shaft cavity 12 receives sufficient and appropriate lubrication, improving the operational stability of vibrating screen 11; oil return pipe 13 and oil return filter 6 work together to keep the lubricating oil clean during circulation; the connection of the control system enables intelligent operation of the entire lubrication system, automatically adjusting the working status of each component according to the oil temperature.

[0023] The control system includes a temperature controller and an alarm unit. The signal output terminal of the temperature sensing unit is electrically connected to the signal input terminal of the temperature controller. The first control output terminal of the temperature controller is electrically connected to the controlled terminal of the heating unit 2, used to start the heating unit 2 when a signal below the first temperature threshold is received, and to shut down the heating unit 2 when a signal reaching the second temperature threshold is received. The second control output terminal of the temperature controller is connected to the alarm unit, used to drive the alarm unit to issue a shutdown alarm for the vibrating screen 11 when a signal reaching the third temperature threshold is received. Through the connection and control logic between the temperature controller, the temperature sensing unit, the heating unit 2, and the alarm unit, precise temperature control and timely handling of abnormal situations are achieved. When the oil temperature is below the appropriate range, the heating unit 2 is automatically started, avoiding the problem of difficulty in starting the equipment due to increased lubricating oil viscosity at low temperatures; when the oil temperature reaches the normal operating range, the heating unit 2 is shut down in time, saving energy and preventing the oil temperature from becoming too high; and when the oil temperature abnormally rises to the third temperature threshold that may damage the equipment, the alarm unit promptly issues an alarm and shuts down the equipment, protecting the key components of the vibrating screen 11 from damage and greatly improving the safety and stability of the equipment.

[0024] In a preferred embodiment, the filter device 5 is a high-pressure fine filter, and the filter device 5 is connected to the oil pump 4 via a flexible connector 7. Using a high-pressure fine filter can more effectively filter out minute impurities in the lubricating oil, further improving the cleanliness of the lubricating oil, reducing damage to the equipment caused by wear due to impurities, and extending the service life of key components such as the excitation shaft cavity 12. The flexible connector 7 connects the filter device 5 and the oil pump 4, effectively buffering the vibration generated by the oil pump 4 during operation, preventing vibration from damaging the filter device 5 and the entire connecting pipeline, and ensuring the operational stability and reliability of the system.

[0025] In a preferred embodiment, the oil return filter 6 is a detachable magnetic filter. The detachable magnetic filter is easy to disassemble and clean, and is highly efficient at intercepting magnetic impurities during the lubricating oil return process. Magnetic impurities can cause severe wear on equipment components during lubricating oil circulation. Removing these impurities by the magnetic filter effectively reduces such wear, extends the overall service life of the equipment, and its detachable nature also facilitates maintaining the filtration effect over a long period.

[0026] In a preferred embodiment, the heating unit 2 is either an armored electric heating tube or a plate heat exchanger, providing two different types of heating unit 2 to meet the needs of different users and application scenarios. The armored electric heating tube has a simple structure and high heating efficiency, making it suitable for scenarios with high heating speed requirements and limited space. The plate heat exchanger has good heat exchange performance, can utilize other heat sources for heat exchange, is more energy-efficient, and is suitable for environments with available external heat sources, increasing the system's applicability under different operating conditions.

[0027] In a preferred embodiment, the temperature sensing unit includes a first temperature sensor 3 disposed within the lubricating oil tank 1 and a second temperature sensor disposed on the return oil pipe 13. The presence of temperature sensors both within the lubricating oil tank 1 and on the return oil pipe 13 allows for comprehensive and accurate monitoring of the lubricating oil temperature at different locations. The first temperature sensor 3 acquires the base temperature of the lubricating oil in the tank in real time, providing an understanding of the overall state of the lubricating oil. The second temperature sensor monitors temperature changes in the lubricating oil during the return flow process, helping to promptly detect any abnormal heating during lubrication. The combination of these two sensors provides the control system with richer and more accurate temperature information, thereby enabling more precise control of the heating unit 2 and the identification of any system malfunctions.

[0028] In a preferred embodiment, the control system further includes a timing unit connected to the heating unit 2, the temperature controller, and the alarm unit. The timing unit generates a heating fault alarm signal when the continuous operating time of the heating unit 2 exceeds a preset duration and the lubricating oil temperature still fails to reach the second temperature threshold. The addition of the timing unit allows the control system to monitor the operation of the heating unit 2 more precisely. When the heating unit 2 operates continuously for an excessively long time and the oil temperature fails to reach the expected threshold, it indicates a potential fault in the heating system, such as damage to the heating element or a malfunction in the oil temperature sensor. Timely generation of a heating fault alarm signal allows maintenance personnel to quickly understand system anomalies, promptly troubleshoot and handle them, and avoid energy waste and potential damage to equipment due to prolonged abnormal heating or undetected system faults, thus improving system reliability and maintainability.

[0029] In a preferred embodiment, the distribution device includes a distribution valve 8, multiple oil supply pipes 9, and multiple flow regulating valves 10. One end of the distribution valve 8 is connected to the outlet of the oil pump 4 via a pipeline, and the other end is connected to each oil supply pipe 9. The end of each oil supply pipe 9 away from the distribution valve 8 is connected to the corresponding excitation shaft cavity 12. Each oil supply pipe 9 is equipped with a flow regulating valve 10. The structural design of the distribution device allows for precise adjustment of the lubricating oil flow supplied to each excitation shaft cavity 12 according to the actual lubrication requirements of different excitation shaft cavities 12 of the vibrating screen 11. The distribution valve 8 centrally distributes the lubricating oil, and the multiple oil supply pipes 9 ensure that the lubricating oil can be delivered to each excitation shaft cavity 12. The flow regulating valves 10 make lubrication more precise and flexible. Different excitation shaft cavities 12 may have different requirements for the amount of lubricating oil in actual operation. By adjusting the flow rate, it can be ensured that each excitation shaft cavity 12 receives appropriate lubrication, improving the lubrication effect and thus enhancing the overall stability and reliability of the vibrating screen 11.

[0030] Example 2

[0031] This embodiment also provides a vibrating screen 11, integrating an intelligent lubrication system as described in any of the embodiments in Example 1. Integrating this intelligent lubrication system into the vibrating screen 11 comprehensively upgrades its lubrication protection. The intelligent lubrication system can automatically adjust according to the lubricating oil temperature and operating conditions, reducing manual maintenance costs and equipment failures caused by improper lubrication. Through a reliable filter device 5, precise temperature control, and reasonable flow distribution, the service life of key components of the vibrating screen 11, such as the excitation shaft cavity 12, is effectively extended, improving the stability and reliability of the vibrating screen 11's operation, thereby enhancing the overall working efficiency and performance of the vibrating screen 11.

[0032] Example 3

[0033] This utility model also provides a method for using the intelligent lubrication system for a vibrating screen as described in any of Embodiment 1, comprising the following steps:

[0034] (I) Preparations before system startup

[0035] Check component installation and connection

[0036] Confirm that the lubricating oil tank 1 is installed in the appropriate position, and that all components, such as the heating unit 2, temperature sensing unit, filter device 5, distribution device, return oil filter device 6, oil pump 4, and control system, are correctly installed and connected according to design requirements. For example, check whether the heating unit 2 is well connected to the lubricating oil tank 1; if it is an armored electric heating tube, check whether its installation inside the lubricating oil tank 1 is secure; and whether the pipe connection between the plate heat exchanger and the lubricating oil tank 1 is sealed.

[0037] Check whether the pipeline connection between oil pump 4 and lubricating oil tank 1 and filter device 5 is tight to avoid leakage; confirm that the connection between distribution valve 8 and oil pump 4 outlet and each oil supply pipe 9 through pipeline is correct; the connection between each oil supply pipe 9 and the corresponding excitation shaft cavity 12 is normal; the connection between return oil pipe 13 and excitation shaft cavity 12 and lubricating oil tank 1 inlet is also normal.

[0038] Check whether the installation positions of the first temperature sensor 3 in the lubricating oil tank 1 and the second temperature sensor on the return oil pipe 13 in the temperature sensing unit are appropriate and whether they can accurately measure the oil temperature; check whether the signal connection between the control system and the temperature sensing unit, heating unit 2, oil pump 4, etc. is stable.

[0039] Add lubricating oil

[0040] Add sufficient and appropriate type of lubricating oil to lubrication tank 1 to meet the lubrication requirements of vibrating screen 11. After adding oil, ensure that the oil level is within the normal range, neither too high, which may cause abnormal system pressure, nor too low, which may affect the lubrication effect.

[0041] (II) System Startup and Operation

[0042] Startup System

[0043] Turn on the power to the vibrating screen 11 and the intelligent lubrication system. The control system starts running and receives the oil temperature signal from the temperature sensing unit.

[0044] The temperature sensing unit monitors the lubricating oil temperature in real time. The first temperature sensor 3 measures the oil temperature in the lubricating oil tank 1, and the second temperature sensor measures the oil temperature on the return oil pipe 13 and transmits the signal to the temperature controller in the control system.

[0045] Temperature regulation process

[0046] If the oil temperature signal received by the temperature controller is lower than the first temperature threshold, it indicates that the lubricating oil temperature is too low, which is not conducive to the start-up and operation of the equipment. At this time, the temperature controller sends a start signal to the heating unit 2 through the first control output terminal, and the heating unit 2 (such as a sheathed electric heating tube or a plate heat exchanger) starts to work and heats the lubricating oil.

[0047] During the heating process, the temperature sensing unit continuously monitors the oil temperature and feeds the data back to the temperature controller in real time. When the oil temperature reaches the second temperature threshold, the temperature controller issues a shutdown command, and heating unit 2 stops working. At this time, the lubricating oil temperature is within the appropriate operating range, and the system is ready to enter normal lubrication operation.

[0048] Lubrication process

[0049] When oil pump 4 starts, it draws lubricating oil from lubricating oil tank 1 and filters it through a high-pressure fine filter on the pipeline between oil pump 4 and lubricating oil tank 1 to remove impurities and ensure the cleanliness of the lubricating oil.

[0050] After filtration, the lubricating oil is distributed through a distribution device. The lubricating oil output from the oil pump 4 first reaches the distribution valve 8, which then distributes the lubricating oil to each oil supply pipe 9. The flow regulating valve 10 installed on each oil supply pipe 9 can adjust the lubricating oil flow rate according to actual needs, ensuring that the lubricating oil is supplied to the corresponding excitation shaft cavity 12 in an appropriate amount, thus meeting the lubrication requirements of different excitation shaft cavities 12.

[0051] Within each excitation shaft cavity 12, lubricating oil lubricates the components, reducing friction and wear, and ensuring the normal operation of the vibrating screen 11. After lubrication, the lubricating oil flows back to the lubricating oil tank 1 through the return oil pipe 13. At the return oil inlet, it passes through a detachable magnetic filter screen to filter out any impurities that may have entered, ensuring the quality of the returned lubricating oil.

[0052] Monitoring and adjustment during operation

[0053] During system operation, the temperature sensing unit continuously monitors the oil temperature. If the lubricating oil temperature rises abnormally to the third temperature threshold, it indicates that there may be a fault in the system (such as bearing damage causing abnormal oil temperature rise). The temperature controller drives the alarm unit to issue a shutdown alarm for vibrating screen 11 through the second control output terminal, so as to stop the operation of vibrating screen 11 and related equipment in time and avoid further damage to the equipment.

[0054] The timing unit in the control system starts timing to monitor the continuous working time of heating unit 2. If the continuous working time of heating unit 2 exceeds the preset duration, and the lubricating oil temperature still has not reached the second temperature threshold, it indicates that the heating system may be malfunctioning. The timing unit generates a heating fault alarm signal to notify the operator to inspect and repair it.

[0055] (III) System Maintenance

[0056] Routine inspection

[0057] Regularly check the filtration efficiency of filter device 5 and observe the degree of clogging. If the clogging is severe, it will affect the flow and normal delivery of lubricating oil. Clean or replace the filter element in a timely manner to ensure that filter device 5 is in good working condition.

[0058] Inspect the return oil filter unit 6 (removable magnetic filter) to check the amount of magnetic impurities adsorbed. Regularly disassemble and clean the magnetic filter to maintain its filtering performance.

[0059] Component maintenance

[0060] According to usage and equipment maintenance manual, regularly inspect mechanical components such as oil pump 4 and distribution valve 8 for wear, loosening, etc., and repair or replace them promptly if necessary. Maintain heating unit 2, such as checking for damage to armored electric heating tubes and leaks in plate heat exchangers.

[0061] Check whether the temperature sensors in the control system are accurate and reliable. If a large measurement error is found, calibrate or replace them in time. Check whether the working status of control components such as temperature controllers and alarm units is normal to ensure that the control system can operate stably and accurately.

[0062] Regularly check the condition of the lubricating oil, such as whether the oil quality has deteriorated and whether the viscosity is appropriate. If necessary, replace it with the appropriate lubricating oil according to the equipment requirements.

[0063] Through the above usage methods, the intelligent lubrication system of this patented vibrating screen can effectively provide reliable lubrication for the vibrating screen 11, ensuring stable and reliable operation of the equipment and extending its service life.

[0064] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
