Embodiment 1

[0028] Such as figure 1 As shown, an oil sludge dehydration device includes a tank 1, a drum 2 and a water drawing device 7, the drum 2 is horizontally installed inside the tank 1, and the seal between the drum 2 and the tank 1 is arranged, and the water is drawn The device 7 is fixed on the inner wall of the drum 2, and the water-drawing device 7 communicates with the outside of the casing 1; the drum 2 is provided with a hydrophilic and oleophobic filter layer; The water in the oil sludge sand in 1 is drained into the inside of the drum 2. During the rotation of the drum 2, the water drawing device 7 collects the water inside the drum 2 and exports it out of the box body 1, and the dehydrated oil sludge sand passes through the box body. The pipe 5 below 1 discharges.

[0029] There is no restriction on the structure of the box, any shape is acceptable, as long as the requirements can be met, such as cube, cylinder, cone and so on.

[0030] The drum 2 can be suspended in th...

Embodiment 2

[0035] Such as image 3 As shown, the oil sludge dewatering device also includes a discharge device, the discharge device is installed on the outside of the drum 2, during the rotation of the drum 2, the oil sludge sand sticking to the outside of the drum 2 is scraped off on the discharge device.

[0036] The discharge device can be designed to include a scraper 3 and a discharge bin 4, the scraper 3 is installed obliquely on one side of the discharge bin 4, the lower end of the scraper 3 is connected to the discharge bin 4, and the upper end of the scraper 3 is attached to the rotating The outer surface of the cylinder 2 and the front and rear sides of the scraper are provided with baffles for preventing the leakage of oily sludge and sand. During the rotation of the drum 2, the scraper 3 scrapes off the oily sludge and sand stuck to the outer surface of the drum 2, and Lead to the output bin 4.

Embodiment 3

[0038] The rotating drum 2 is installed in the box body 1 through the rotating shaft 6, the rotating shaft 6 is hollow, and the water drawing device 7 is connected with the rotating shaft 6. After the water drawing device 7 collects the water in the rotating drum 2, the water is exported out of the box through the hollow rotating shaft 6 1 in vitro. The water outlet end of the rotating shaft 6 may be provided with a water recovery device to recycle the exported water.

[0039] Such as Figure 4As shown, the discharge device can also be designed as only the discharge bin 4, the side wall at one end of the discharge bin 4 is arranged to fit the outer surface of the drum 2, and the front and rear sides of the discharge bin 4 are provided with holes for preventing The baffle plate for oily sand leakage, the discharge bin 4 directly scrapes the oily sand stuck on the outer surface of the drum 2 into the discharge bin 4. The discharge bin 4 also plays the role of scraping and coll...

Abstract

The invention discloses an oil sand dewatering device which comprises a box body, a rotary drum and a water drawing device, wherein the rotary drum is horizontally mounted in the box body; the rotary drum and the box body are hermitically arranged; the water drawing device is fixed on the inner side of the rotary drum, and is communicated with the exterior of the box body; the rotary drum is provided with a hydrophilic and oleophobic filtering layer; the hydrophilic and oleophobic filtering layer of the rotary drum drains water in oil sand in the box body into the rotary drum; in a process that the rotary drum rotates, the water drawing device exports water out of the box body after collecting the water in the rotary drum; the dewatered oil sand is discharged from a pipeline below the box body. The oil sand dewatering device disclosed by the invention is simple in structure, does not need heat consumption, and is low in energy consumption and steady in operation; the dewatering problem of the oil sand is easily and efficiently solved; the rotary drum is provided with the hydrophilic and oleophobic filtering layer, so that the water in the oil sand can be drained into the rotary drum, and is discharged out of the box body through the water drawing device; therefore, the water in the oil sand can be effectively removed.

Description

technical field [0001] The invention relates to an oil sludge sand dewatering device, which belongs to the technical field of oil sludge sand treatment. Background technique [0002] Petrochemical enterprises will produce a large amount of oil sludge sand in the production process. Oil sludge sand is generally in a viscous fluid state, with the characteristics of fine particles, poor gradation, high viscosity, high moisture content and not easy to dehydrate. It is a typical viscous colloid . Because the hydrocarbons contained in the oil sludge sand are more harmful to the environment, it has been listed as oily waste (HW08 item) in the "National Hazardous Waste Catalog". Now every major oilfield in the country produces a large amount of oily sand during the production process, and the annual oily sandy production of Shengli Oilfield alone is about 400,000 tons. The direct discharge of oil sludge sand will occupy a large amount of land, and the toxic substances contained in...
