Description

Self-priming oil slick swabbing pig

The utility model relates to the treatment unit of a kind of water or sewage, particularly a kind of device of removing the oily suspended substance.

Fly at by the seashore, the fluid of river, lake, marsh and the other water surface of oil well, rely on manpower or simple and easy apparatus to remove collection usually, the cleaning weak effect, labour intensity is big.The floating type oil slick swabbing pig that Britain Comap's Wei proposes, it is by oil-scraping device, the power transmission unit, oil well pump, buoyancy tank, hinge folding formula cover cap, composition such as pipeline and flowrate control valve, its cleaning function is to be finished as mode mutually by following: one group of disk of oil-scraping device utilizes card absorption oil slick in rotation, oil scraping plate is swept and is scraped the fluid that adsorbs on the disc face, fluid enters oil trap along the oil transportation guide groove that is connected with oil scraping plate, oil well pump transfers to petroleum reservoir with fluid in the oil groove, similarly equipment also has China's patent ZL91211018.X name to be called the rotating disc type oil receiving equipment, and the weak point of above-mentioned these oil slick swabbing pigs is:

1. disc is when rotating, and the quantity that oil slick is affixed to card to extrapolation, has been reduced with the oil slick of its proximity in the disc end;

2. enter the oil slick of disc workspace, can escape along the gap between two discs greatly, also reduce the quantity that oil slick is affixed to card;

3. above-mentioned oil slick swabbing pig all is to adopt external placed type oil trap structure, for guaranteeing that oil-collecting is not subjected to overflowing into of extraneous water medium, the aperture position of oil trap must be higher than the water surface, for making oil scraping plate energy works better, the rotation center of disc will be far above the water surface, the immersed depth of disc reduces, and disc face adsorption function subtracts greatly.

The purpose of this utility model is that a kind of improved self-priming oil slick swabbing pig will be provided, and it had both improved the oil-collecting effect of equipment, made the oil-scraping device compact construction again, increased the service life.

The utility model is achieved in that the oil trap of oil collector sump tank is built-in, be located at the inner chamber of rotary drum, and its opening is again above groove, be that the oil trap opening is above the drum rotating center, increase the immersed depth of rotary drum rotating disk greatly, one side of top, the stage casing opening of built-in oil trap is established one group of oil scraping plate, because embedding structure makes the oil scraping plate designs simplification, size is dwindled, establish uniform tooth on the rotating disk of rotary drum, blade is set when rotating disk rotates on dentalation and the tooth, the effect of collecting oil slick is arranged, the oil slick function of depositing between two rotating disks is arranged simultaneously, it is escaped from turntable clearance, rotary drum is bearing on the oil trap, makes oil trap have the effect of rotary drum stationary shaft concurrently.

The utility model adopts structures such as establishing blade on built-in oil trap, dentation rotating disk and the tooth, the function that makes equipment receive oil, retaining oil and absorption oil obviously improves, thereby raising sweeping efficiency, built-in oil trap is the reduction equipment size both, simplified apparatus structure is again established blade on the tooth and rotary drum is bearing in oil trap, and the rigidity of equipment moving member is heightened, improve transmission condition, increase service life of equipment.

Concrete structure of the present utility model is drawn by following examples and accompanying drawing thereof.

Fig. 1 is according to the oil slick swabbing pig synoptic diagram that the utility model proposes.

Fig. 2 is oil trap and a rotary drum part-structure longitudinal section among Fig. 1.

Fig. 3 is Fig. 1 structure rotary drum work synoptic diagram.

Fig. 4 is a toothed portion partial enlarged drawing among Fig. 3.

Fig. 6 is the side-view of Fig. 5.

Fig. 7 is the front view of blade among Fig. 4.

Fig. 8 is the side-view of Fig. 7.

With reference to Fig. 1,2,3 self-priming oil slick swabbing pigs are by oil collector sump tank 1, rotary drum 2, transmission mechanism 3, power unit 4, petroleum reservoir 5 and buoyancy tank 6 are formed, the inner chamber that the oil trap 11 of oil collector sump tank 1 is arranged on rotary drum 2 is built-in, also be the bolster of rotary drum 2 simultaneously, oil trap 11 in a tubular form, its two ends are fixedly supported upon petroleum reservoir, the both ends open subtend petroleum reservoir of oil trap, establish long strip shape opening 111 on the stage casing of oil trap, one side of opening 111 is established one group of oil scraping plate 12, it is each rotating disk 21, establish an oil scraping plate 12 in 210 the interval, the dual-side of oil scraping plate 12 is relative with the card of rotating disk on the drum respectively, and maintain and rotate same crack, make oil scraping plate can strike off fluid on the rotating disk card, the palpus that can not influence rotating disk again freely rotates.Establish one group of rotating disk 21 on the rotary drum 2, the bigger rotating disk of a thickness of slab 210 is respectively established at rotary drum 2 two ends, establishes bearing 212 on the propeller boss 211 of rotating disk 210, and bearing 212 is installed on the oil trap 11.

With reference to Fig. 3,4,5,6,7 and 8, establish uniform tooth 22 on the rotating disk 21,210 of rotary drum 2, the profile of tooth indentation, the flank of tooth 221 subtend waters surface before tooth 22 entry during rotating disk 21,210 rotations, welding stator blades 23 on the tooth 22, the body 230 of blade 23 is fitted with the back of tooth of tooth 22 220, and the segmentation folding body 231 of blade is rolled over the gap location that embeds two rotating disks 21,210 respectively from the flank of tooth 221 places of tooth 22.

During work, power unit 4 drives rotary drum 2 through transmission mechanism 3, rotary drum 2 is around 11 rotations of fixed oil trap, as shown in Figure 3, have fluid to rotating disk 21 when the flank of tooth 221 and leaf 23 entry, the function of pinching in 210, blade can also be blocked in two rotating disks 21 simultaneously, fluid in 210 the interval is excessive and be gathered in card, rotating disk 21,210 with the fluid 7 that is adsorbed in card go to the top, scrape sweeping of oil scraping plate 12, flow into oil trap 11 along oil scraping plate 12 through the top of oil trap 11 opening 11, fluid 7 flows to both ends open 110 and enters petroleum reservoir 5 from oil trap 11 again, along with self-priming oil slick swabbing pig is constantly collected fluid 7 advance petroleum reservoir 5 and reached the purpose of cleaning the water surface moving of the water surface.Built-in oil trap 11 increases the immersed depth of rotating disk 21,210 simultaneously, thereby strengthens the area of absorption fluid, further improves the sweeping efficiency of self-priming oil slick swabbing pig.
