Description

Technical Field

[0001] This disclosure generally relates to the field of oil filling and unloading, and particularly to an integrated, convenient, and automated equipment for precise oil filling and unloading. Background Technology

[0002] During vehicle or internal combustion engine use, engine oil typically needs to be changed after a period of time to ensure normal operation. This requires the unloading and recycling of waste engine oil and the addition of new engine oil. When the engine oil is worn out, it also needs to be replenished with new oil regularly. Existing technologies include automatic oil filling equipment, but these devices are very heavy and inconvenient to move. There is no automatic equipment for unloading waste engine oil, resulting in slow unloading speed, incomplete unloading of oil from the tank, and potential oil leakage that could contaminate the operating environment. Furthermore, existing technologies do not integrate automated equipment for adding and unloading engine oil, leading to slow overall oil change efficiency.

[0003] Meanwhile, existing technologies cannot precisely control oil filling and unloading, so there is an urgent need for an integrated, convenient, and automated oil filling and unloading device to meet the demand. Summary of the Invention

[0004] According to an example embodiment of this disclosure, an integrated, portable, and automated oil filling and unloading device is provided to at least partially solve the problems existing in the prior art.

The filling module includes a first oil tank, a first electric pump, a first oil filter, a first valve group, a first oil pipe collector, and a first oil connector. The first oil tank, first electric pump, first oil filter, first valve group, and first oil connector are connected by oil pipes to form a filling circuit. The first oil pipe collector is used for winding and unwinding the filling circuit oil pipes. The unloading module includes a second oil tank, a second electric pump, and a second oil filter. The system includes a first oil tank, a second valve group, a second oil pipe collector, a second oil connector, a second oil tank, a second electric pump, a second oil filter, and the second valve group and the second oil connector connected by oil pipes to form an oil unloading circuit. The second oil pipe collector is used to wind and unwind the oil pipes of the oil unloading circuit. An electronic level gauge is installed inside the first oil tank and / or the second oil tank. A controller is installed on the control box, and the electronic level gauge, the first electric pump, the first valve group, the second electric pump, and the second valve group are respectively connected to the controller for communication. It also includes an air compressor pump and a cleaning pipeline. The air compressor pump is connected to the controller for communication, and the air compressor pump can clean the oil tank through the cleaning pipeline.

[0006] In some embodiments, during a normal refueling operation, the controller performs the following operations: in response to the input amount to be refueled, it acquires the oil level value of the electronic level gauge in the first oil tank; when the amount to be refueled exceeds 90% of the oil level value of the electronic level gauge in the first oil tank, it does not perform the refueling operation and issues an alarm; when the amount to be refueled does not exceed 90% of the oil level value of the electronic level gauge in the first oil tank, it performs the refueling operation and acquires the oil level value signal of the electronic level gauge; when the oil level value of the electronic level gauge drops to 90% of the amount to be refueled, the refueling flow rate is reduced to 40%-60% of the normal rate to complete the addition of the remaining oil.

[0007] In some embodiments, when performing oil circulation cleaning operations, a first oil tank or a second oil tank is used to provide circulation oil supply and unloading space for the refueling module and the unloading module. The first oil tank or the second oil tank has a pre-stored amount of oil exceeding 15% of the oil level value of the electronic level gauge. The controller performs the following operations: simultaneously starts the first electric pump and the second electric pump, and collects the oil level value of the electronic level gauge in the first oil tank or the second oil tank. When the oil level value of the electronic level gauge in the first oil tank or the second oil tank rises or falls by 5%, simultaneously stops the first electric pump and the second electric pump and alarms.

The first and second oil drums are detachably housed within the housing. The air compressor pump and cleaning pipeline can be optionally installed within the housing of either the refueling module or the unloading module.

[0026] In some embodiments, during normal refueling, the controller performs the following operations: In response to the input amount to be refueled, it acquires the oil level value of the electronic level gauge in the first oil tank; when the amount to be refueled exceeds 90% of the oil level value of the electronic level gauge in the first oil tank, the refueling operation is not performed and an alarm is triggered; when the amount to be refueled does not exceed 90% of the oil level value of the electronic level gauge in the first oil tank, the refueling operation is performed and the oil level value signal of the electronic level gauge is acquired; when the oil level value of the electronic level gauge drops to 90% of the amount to be refueled, the refueling flow rate is reduced to 40%-60% of the normal speed to complete the addition of the remaining oil. Normal refueling operation refers to adding oil at a uniform speed when new engine oil needs to be added.
