[0022] The present invention provides an oil-water separation device, which is used to separate oil and dirt in a water tank; the oil-water separation device comprises: a shell, a driving wheel arranged at one end of the shell, a synchronous belt arranged around the driving wheel, a driven wheel arranged in the synchronous belt and located on the opposite side of the driving wheel, and a driving mechanism for driving the driving wheel to rotate; the shell is detachably arranged on a side wall of the water tank; an oil scraper plate and an oil guide groove connected to the oil scraper plate are arranged on a side wall of the shell close to the synchronous belt; a side of the synchronous belt close to the driven wheel can extend into the water tank, and the driving wheel drives the synchronous belt to rotate to absorb the oil and dirt in the water tank and transport it to the scraper plate, and the oil and dirt on the synchronous belt are discharged through the oil guide groove by the scraper plate.

[0023] The present invention provides an oil-water separation device, which drives the synchronous belt to rotate through a driving mechanism, so that the oil in the water tank is adsorbed onto the synchronous belt. When the synchronous belt moves to the position of the scraper plate, the scraper plate scrapes the oil adhered to the surface of the synchronous belt off the synchronous belt and discharges it through the oil guide groove. The synchronous belt rotates in a circle, continuously adsorbs the oil in the water tank and discharges it, and the oil removal efficiency is high.

[0024] The oil-water separation device is described below in conjunction with specific embodiments to further understand the inventive concept of the oil-water separation device.

[0025] In one embodiment, if Figure 1-2As shown, an oil-water separation device is used to separate oil and dirt in a water tank 7; the oil-water separation device comprises a housing 1, a driving wheel 2 arranged at one end of the housing 1, a synchronous belt 3 arranged around the driving wheel 2, a driven wheel 4 arranged in the synchronous belt 3 and located at the opposite side of the driving wheel 2, and a driving mechanism 5 for driving the driving wheel 2 to rotate. The output shaft of the driving mechanism 5 is drivingly connected to the rotating shaft of the driving wheel 2, and the rotating shaft of the driving wheel 2 is rotatably connected to the two opposite side walls of the housing 1. The housing 1 is detachably arranged on a side wall of the water tank 7, and can be detachably connected to the housing 7 by, for example, screwing or snapping. An oil scraper 11 and an oil guide groove 12 connected to the oil scraper 11 are provided on a side wall of the housing 1 close to the synchronous belt 3. The oil scraper 11 is obliquely installed on one side wall of the housing 1. The oil scraper 11 is installed toward the direction of the driving wheel 2, that is, the oil scraper 11 is installed obliquely upward. An opening is provided at the position where the oil scraper 11 is installed on the side wall of the housing 1. The oil guide groove 11 passes through the opening and is connected to the oil scraper 11. The free end of the oil scraper 11 abuts against the synchronous belt 3. One end of the synchronous belt 3 close to the driven wheel 4 extends into the water tank 7, and the driving mechanism 5 drives the driving wheel 2 to rotate clockwise, and the driving wheel 2 drives the synchronous belt 3 to rotate clockwise. The synchronous belt 3 below the liquid level of the water tank 7 can absorb oil stains, and as the synchronous belt 3 rotates clockwise, when it is at the position of the scraper plate 11, the scraper plate 11 scrapes the oil stains on the synchronous belt 3 off the synchronous belt, and the scraped oil stains flow along the scraper plate 11 to the oil guide groove 12 and are discharged from the oil guide groove 12.

[0026] In another embodiment, if Figure 1-2 As shown, the oil-water separation device further includes a synchronous belt tensioning strip 6, one end of which is rotatably connected to the rotating shaft 21 of the driven wheel 4, and the other end of which is slidably connected to the housing 1. That is, the distance between the driven wheel 4 and the driving wheel 2 is adjusted by the relative sliding connection between the synchronous belt tensioning strip 7 and the housing 1, so that the synchronous belt 3 is tensioned.

[0027] Preferably, if Figure 2 As shown, a strip hole 61 is provided at one end of the synchronous belt tensioning strip 6 away from the driven wheel 4, and the strip hole 61 is connected to the housing 1 through a bolt 13. That is, when adjusting the position of the driven wheel 4, the bolt 13 is loosened, the position of the synchronous belt tensioning strip 6 is moved in the vertical direction, and the spacing between the driven wheel 4 and the driving wheel 2 is adjusted. After the synchronous belt 3 is tightened, the bolt 13 is tightened to fix the position of the driven wheel 4. Thus, the tension adjustment of the synchronous belt 3 is completed.

[0028] In another embodiment, if Figure 2As shown, the free end of the oil scraper 11 faces the driving wheel 2, and the angle between the oil scraper 11 and the housing 1 is 30-60°, that is, the oil scraper 11 is installed on the housing 1 at an angle, so that the oil scraped off by the oil scraper 11 can flow into the oil guide groove 12 under the action of gravity.

[0029] In another embodiment, if Figure 2 As shown, the oil guide groove 12 is installed along the extension direction of the oil scraper plate 11, the free end of the oil guide groove 12 is outside the shell 1, and the other end of the oil guide groove 11 is connected to the oil scraper plate 11. The oil guide groove 12 and the oil scraper plate 11 can be integrally formed, and the free end of the oil guide groove 12 is opposite to the free end of the oil scraper plate 11, that is, the oil guide groove 11 is installed tilted downward, so that the oil and dirt flowing into the oil guide groove 11 can be discharged smoothly under the action of gravity.

[0030] In another embodiment, a recovery box is provided below the oil guide groove 12 , and the oil discharged from the oil guide groove 12 is recovered through the recovery box.

[0031] In another embodiment, the synchronous belt 3 is made of an oleophilic material. Preferably, the synchronous belt 3 is made of an oleophilic and hydrophobic material.

[0032] In another embodiment, the synchronous belt 3 is made of oleophilic polyolefin plastic or fluoroplastic.

[0033] In another embodiment, the surface of the synchronous belt 3 is coated with a fluorocarbon coating or a graphene coating with oleophilic properties.

[0034] In another embodiment, if Figure 2 As shown, the driving wheel 2 and the driven wheel 4 are gears, and the back of the synchronous belt 3 is provided with corresponding teeth 31, and the synchronous belt 3 is respectively meshed with the driving wheel 2 and the driven wheel 3. That is, in the present invention, the meshing of the synchronous belt 3 with the driving wheel 2 and the driven wheel 4 prevents the synchronous belt from slipping and deviating from the driving wheel and the driven wheel, so that the rotation of the synchronous belt 3 is more stable.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
