Description

Technical Field

[0001] This utility model relates to the field of wastewater equipment, specifically to an oil skimming device for the oil collection tank of an oil-water separator. Background Technology

[0002] Oil-water separators need to separate the surface grease layer. Existing oil scraping devices often use a single roller to drive a scraper to collect the grease layer. However, the amount of grease scraped by a single roller is limited. When it comes to large oil-water separators, it cannot meet the needs of collecting a large amount of grease layer. Furthermore, due to wear, a single roller often needs to be replaced as a whole, resulting in high maintenance costs. Utility Model Content

[0003] The purpose of this utility model is to provide an oil skimming device for the oil collection tank of an oil-water separator, so as to solve the problem mentioned in the background art that oil-water separators urgently need a large number of collection devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oil scraping device for an oil-water separator's oil collection tank, comprising an oil scraping groove, a drive shaft, a driven shaft, and a scraper, characterized in that: it further comprises a chain assembly, the chain assembly consisting of two chains and pins, the two chains being arranged in parallel and connected by the pins; the drive shaft and driven shaft are each provided with a sprocket, the sprockets connecting the chain assembly to the drive shaft and driven shaft, allowing the drive shaft to drive the driven shaft and chains to rotate; the scraper comprises a scraper head and a scraper base, the top of the scraper base being connected to the scraper head, and the bottom of the scraper base having a mounting hole, through which the scraper base is mounted on the pin, thus mounting the scraper on the chain assembly; the oil scraping groove is a concave plate; the bottom of the scraper base is mounted on two adjacent pins; a chain limiting plate is also provided, the chain limiting plate being an inverted concave plate that interlocks with the oil scraping groove, restricting the movement of the chain, thereby allowing the scraper to slide inside the oil scraping groove.

[0005] Preferably, one end of the drive shaft is connected to a motor.

[0006] Preferably, the driven shaft is further connected to a tensioning device; the tensioning device includes an adjusting seat, an adjusting rod, an adjusting nut, and a bearing seat. The adjusting seat has an elongated slot for adjusting and sliding the driven shaft. The adjusting rod is connected to the driven shaft through the bearing seat. One end of the adjusting rod is fixedly connected to the bearing seat, and the other end passes through the adjusting seat and is threadedly connected to the adjusting nut. Rotating the adjusting nut causes the adjusting rod to move the bearing seat, thereby moving the driven shaft on the adjusting seat and tensioning the chain.

[0007] Preferably, the tensioning device is also provided with a protective cover.

[0008] Preferably, the bottom of the chain limiting plate and the oil scraper groove are provided with mounting holes for installing the chain limiting plate and the oil scraper groove inside the oil-water separator.

[0009] Preferably, the scraper head is a rubber scraper head.

[0010] Preferably, the two sides of the scraper base are triangular with a wider bottom and a narrower top, and the mounting holes are symmetrically arranged at the bottom of both sides of the scraper base.

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

[0012] The chain assembly can drive multiple scrapers to move simultaneously. Since each scraping is done to prevent the grease from containing too much water, only the top layer of grease is scraped off. The more scrapers there are, the more grease is scraped off. Furthermore, with the chain scraping structure, the chain and the scraping groove are parallel and there is a limit plate, so the scraper can run tightly in the scraping groove, and the scraped grease is not easy to slip off.

[0013] The oil scraper groove and the limiting plate can effectively restrict the movement of the chain and prevent the scraper from colliding with the oil scraper groove. The oil scraper groove is a concave plate, which can also limit the scraper from scraping oil containing grease.

[0014] Tensioning devices can effectively prevent chain fatigue and improve the overall service life.

[0015] The detachable rubber scraper head only requires replacing the damaged scraper head during each maintenance, resulting in lower maintenance costs. Attached Figure Description
