Description

Technical Field

[0001] This utility model relates to the field of oil supply equipment technology, and in particular to an automatic oil supply device for industrial lubricating oil. Background Technology

[0002] Industrial lubricants, as critical lubricating media in industrial fields, include, but are not limited to, cutting fluids, hydraulic oils, rust-preventive oils, and slideway oils. Typically, industrial lubricants are stored in concentrated form in specially structured oil drums. These drums have an oil outlet and an air inlet at the top, with the oil outlet connected to an oil pipe equipped with a manual mechanical valve. Traditional oil dispensing requires tilting the entire oil drum on a dedicated drum rack, ensuring the oil outlet is directly below the air inlet, and then opening the mechanical valve to dispense the oil. However, traditional oil storage and dispensing methods have the following significant drawbacks:

[0003] 1. Cumbersome operation and safety hazards: The tilting of the oil drums and reliance on drum racks make the operation time-consuming and labor-intensive, requiring a large amount of floor space for storage and operation. More importantly, the tilted state of the oil drums increases the risk of tipping over and may cause accidents such as sprains due to improper operation, posing inherent safety hazards.

[0004] 2. Poor oil extraction control precision: Relying on manual operation of mechanical valves to open or close them makes it difficult to achieve precise flow or capacity control of oil extraction, which can easily lead to excessive or insufficient oil extraction.

[0005] 3. Lack of status monitoring: There is a lack of effective means to monitor the remaining oil in the container and the quality of the oil, making it impossible to obtain information on the status and quantity of the oil in a timely manner.

This completely avoids the operational risks and space occupation associated with manual handling and tilting of oil drums. This significantly improves safety; the PLC precisely controls the start, stop, and switching of the bidirectional pump and solenoid valve based on feedback from the monitoring sensor group (real-time oil status, remaining quantity, and flow rate), ensuring accurate and controllable oil supply and solving the error problem of manual operation; through real-time monitoring of multiple parameters (oil quality, quantity, and temperature) by the monitoring sensor group and the alarm prompts / remote communication capabilities of the control panel, the reliability of oil quality is guaranteed, and maintenance personnel can conveniently monitor the status, set parameters, or remotely receive early warnings, ultimately greatly improving the convenience, safety, accuracy, and reliability of industrial lubricant supply.

[0047] 4. The monitoring sensor group (including oil level sensor, concentration sensor, pH sensor, temperature sensor and flow meter) is integrated in the oil classification tank and provides real-time data feedback through PLC. It can continuously monitor key parameters of industrial lubricating oil (such as concentration, pH value, temperature and flow rate), detect deterioration or abnormalities (such as oil aging or blockage) in a timely manner, and provide early warning function in combination with the upper / lower limit alarm indicator on the control panel to ensure oil quality stability and supply safety.

[0048] 5. The observation window (circular design with a transparent protective plate) and monitoring hole (circular design for sensor installation) on the top of the oil storage and sorting box facilitate visual inspection and sensor maintenance, effectively improving the accessibility and safety of the device (such as quickly identifying oil level or abnormal phenomena). At the same time, the transparent protective plate reduces the risk of contamination and damage, lowers maintenance costs, and is particularly suitable for harsh industrial environments.

[0049] 6. The three-way directional valve, oil outlet valve, and on / off valve are all solenoid valves, and work in conjunction with the bidirectional pump (which supports forward and reverse flow) to achieve precise regulation of oil flow direction and flow rate (such as switching the oil inlet / outlet path through the three-way directional valve), optimize the industrial lubricant supply process (such as recovering or replenishing oil), and at the same time, the rapid response of the solenoid valve enhances the reliability of the device and reduces energy consumption and leakage risk.

[0050] 7. The control panel integrates a display, setting buttons, threshold adjustment buttons (increase / decrease), alarm indicator lights, and alarm clearing buttons.
