Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment equipment for the production of lubricating oil from waste mineral oil, specifically a wastewater treatment equipment for the production of lubricating oil from waste mineral oil. Background Technology

[0002] The main product of waste mineral oil recycling is lubricating oil base oil, which is widely used in industrial production, transportation and other fields. With increasingly stringent environmental protection policies and growing market demand, the waste mineral oil recycling industry will usher in broad development prospects.

[0003] In existing technologies, wastewater treatment equipment is a crucial step in ensuring environmental compliance during the regeneration of lubricating oil from waste mineral oil. However, the core component of this equipment, the filter element, is used to remove impurities and pollutants from the wastewater. Currently, most existing wastewater treatment systems integrate the filter element with the equipment. While this design ensures a degree of compactness and stability, it also presents significant cleaning challenges. Because the filter element is tightly connected to the equipment, disassembly is complex and requires specialized tools and personnel, increasing both the difficulty and time required for cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment device for the regeneration of waste mineral oil into lubricating oil, so as to solve the problems mentioned in the background art.

[0006] Preferably, the top of the rotating shaft is inserted into the interior of the wastewater treatment tank, and the top of the rotating shaft is connected to a rotating disk. A slot is provided in the middle of the top of the rotating disk, and a mounting base is inserted into the slot. The motor can drive the rotating shaft to rotate the rotating disk and the mounting base, thereby generating centrifugal force.

[0008] Preferably, the top of the mounting base has a first support column on the outside of the activated carbon filter element, which supports the activated carbon filter element and prevents it from deforming. The mounting base has a second support column on the inside of the activated carbon filter element, which supports both the large-diameter filter element and the small-diameter filter element and prevents them from deforming.

[0009] Preferably, the large-diameter filter element, the small-diameter filter element, the activated carbon filter element, and the mounting base are all provided with fixing screw holes around their top edges. Fixing bolts are inserted into the overlapping fixing screw holes around the top edges of the large-diameter filter element, the small-diameter filter element, the activated carbon filter element, and the mounting base to fix the large-diameter filter element, the small-diameter filter element, and the activated carbon filter element to the top of the mounting base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In practical use, as described in this utility model, the motor is first started, causing it to drive the rotating disc, which is held in place by the mounting base, to rotate via the rotating shaft. Wastewater from the production of lubricating oil from recycled waste mineral oil enters the large-diameter filter element through the inlet in the middle of the tank cover. The wastewater is then thrown outwards by the centrifugal force generated by the rotation of the mounting base. At this point, the large-diameter filter element performs the first filtration, retaining larger particles. The small-diameter filter element then performs a second filtration, retaining smaller particles. Finally, the wastewater passes through a recirculating filter... The activated carbon filter cartridge performs the third filtration, absorbing fine impurities and oil from the wastewater to complete the filtration. The filtered water is discharged from the outlet at the bottom of the wastewater treatment tank. When cleaning or replacing the filter cartridges, first remove the tank cover, then lift the mounting base from the top of the rotating plate using the first and second support columns. Next, remove the fixing bolts from the screw holes around the top of the large-diameter filter cartridge, small-diameter filter cartridge, activated carbon filter cartridge, and mounting base. This allows for the sorting and quick cleaning and replacement of the large-diameter filter cartridge, small-diameter filter cartridge, activated carbon filter cartridge, and mounting base.
