Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separators, in particular to an oil-water separator installation structure for a hydraulic excavator. Background Art

[0002] The oil-water separator is a device, which is divided into two types: catering oil-water separator and industrial oil-water separator. The working principle and workflow of the oil-water separator system are as follows: 1. Water enters from the AOD pump (air diaphragm) 2. The flow control valve enters 3. The first-stage honeycomb chamber is flushed with water. Since there are many tight honeycomb compartments inside, the tiny particles in the water settle in the honeycomb chamber during the water upflow process. The wastewater flows up to 4. The mesh water distribution holes (5 / 32) enter 5. The adsorption chamber and extraction chamber, the water flows into the oil adsorption chamber composed of JT57 liquid filter media. In this process, oil and Grease is adsorbed in large quantities and a large amount of complex heavy metals, organic matter, TSS, BTEX, PCB and many pollutants in water are extracted. Then the water flow turns upward in the adsorption chamber and enters the 6th second-stage honeycomb chamber. The water flows through the second-stage tight honeycomb barrier and changes direction three times to flow up and down. The remaining trace oil will float up and be collected in the upper part. The water flows into the 7th clean water chamber and is finally discharged from the bottom of the clean water chamber. The remaining trace oil in the second-stage honeycomb chamber and the clean water chamber is skimmed by the skimmer set on the top to an external oil storage container for removal.

[0003] The mounting fulcrum of the existing oil-water separator is fixed on the bracket by a shock absorber. Although it can timely and effectively reduce the excitation vibration transmitted by the platform and the supporting surface, the mounting bracket of the existing oil-water separator does not have a buffering effect, which reduces the installation reliability of the oil-water separator. In addition, the existing oil-water separator is prone to clogging, which makes it difficult to clean.

[0004] To this end, we propose a hydraulic excavator oil-water separator installation structure. Utility Model Content
