Description

Technical Field

[0001] The utility model relates to the technical field of waste oil recovery, in particular to a solvent recovery and treatment device for waste oil processing. Background Art

[0002] Waste oil refers to oil that is purified or synthesized from crude oil and contaminated by physical or chemical impurities after use. Simply put, waste oil, as the name suggests, is oil that comes from petroleum or synthetic oil and has been used. In the industrial production industry, a large amount of power oil and lubricating oil are needed, and new lubricating oil and power oil need to be replaced every once in a while.

[0003] If a large amount of waste oil is discharged directly, it will cause environmental pollution and waste of resources. Therefore, many industries will separate and regenerate the waste oil. For example, the utility model patent with announcement number CN215026542U relates to a waste lubricating oil separation device, including a filter box, wherein two layers of filter plates are arranged in sequence from top to bottom in the filter box, the left sides of the two layers of filter plates are higher than the right sides, a scraper is arranged on the filter plate, a slag transport box is arranged on the right side of the filter plate, a suction pump is fixed on the left side of the filter box, an oil storage tank is arranged at the bottom of the filter box, and the waste lubricating oil Pour the oil into the filter box and filter out impurities through the filter plate. The filtered lubricating oil enters the oil storage tank. Observe whether the lubricating oil is filtered thoroughly. If it needs to be filtered again, the lubricating oil is sucked to the filter plate by a suction pump and filtered again. If it no longer needs to be filtered, the lubricating oil is discharged out of the filter box. After the filtration work is completed, the filter residue accumulated on the two layers of filter plates can be scraped onto the residue transport box by a scraper, and then the residue transport box is pulled out of the filter box. The waste lubricating oil filtering device can filter repeatedly for many times, and the scraper and the residue transport box make it more convenient for personnel to clean the filter residue, thereby improving the filtration quality and efficiency of the waste lubricating oil.

[0004] However, there are still some problems. Although the filter plate can be easily cleaned by a scraper, the filter plate is fixed to the card plate, and the card plate is plugged into the card slot on the fixed block, so that when the filter plate is damaged, it is not easy to remove it from the filter box. There is inconvenience in subsequent maintenance and replacement of the filter plate. Therefore, a solvent recovery and processing device for waste oil processing is proposed to solve the above problems. Utility Model Content

The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0040] The working principle of the above embodiment is:

[0041] (1) After the waste oil with flocculant added is added into the storage box 1 through the oil inlet 2, the waste oil will move downward due to gravity, so that the impurities will be filtered out when the waste oil passes through the filter component 3. The filtered waste oil is pulled into the oil-water separator 5 through the connecting pipe 17 for dehydration and impurity removal. Then, it enters the distillation kettle 6 through the connecting pipe 17 to distill out different alkanes. Finally, it is pulled into the mixing box 7 through the connecting pipe 17. After observing the volume of the oil in the mixing box 7 through the observation window, the closing plate 16 can be flipped, the feed pipe 14 can be opened, and an appropriate amount of additives can be added into the mixing box 7 through the feed pipe 14. By starting the drive motor 9, the drive rod 10 and the stirring rod 11 are driven to rotate, so that the waste oil and the additives are effectively mixed to obtain lubricating oil, which effectively improves the utilization of resources and makes the whole more practical.

[0042] (2) When the filter assembly 3 needs to be disassembled, the fixing rod 4 can be rotated so that the fixing rod 4 can leave the interior of the fixing block 302 due to the squeezing of the thread. At this time, the fixing block 302 and the fixing plate 301 are no longer fixed, so that the fixing plate 301 can be pulled upward to open the storage box 1. After the fixing block 302 loses contact with the connecting block 303, the filter plate will lose its fixation, so that the filter plate can be moved upward to be taken out. The overall structure is simple, which makes it easy to disassemble the filter assembly 3 later, effectively improving the overall practicality.
