Description

Technical Field

[0001] The present invention relates to the field of oil-water separators, and in particular to an automatic tensioning device for tensioning a belt of the oil-water separator. Background Art

[0002] The existing belt-type oil-water separator uses a rotating belt to remove and discharge the oil from the liquid. However, during use, the belt of the oil-water separator is prone to loosening, which reduces the friction between the belt and the roller, causing the belt to slip. The belt cannot rotate, and oil and water separation cannot be achieved, resulting in equipment failure. Summary of the Invention

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] The present invention provides an automatic tensioning device, which is used for tensioning the belt in an oil-water separator. The automatic tensioning device includes a first U-shaped bracket and a second U-shaped bracket respectively movably arranged on the lower side of the oil-water separator, the first U-shaped bracket and the second U-shaped bracket are connected by a tensioning piece, and the second U-shaped bracket is located below the first U-shaped bracket; the oil-water separator includes an upper roller and a lower roller and a belt arranged around the upper roller and the lower roller; the rotating shaft of the lower roller is rotatably connected to the two side walls of the first U-shaped bracket; the second U-shaped bracket is slidably connected to the two side walls of the oil-water separator; when the second U-shaped bracket is moved in a direction away from the lower roller, the tensioning piece will drive the first U-shaped bracket and the lower roller to move together, thereby tensioning the belt.

[0025] The present invention provides an automatic device, which automatically tensions the belt by pulling the first U-shaped bracket connected to the lower roller downward through the second U-shaped bracket when the belt of the oil-water separator is loose, thereby causing the lower roller to move away from the upper roller to tension the belt.

[0026] The automatic tensioning device will be described below in conjunction with specific embodiments to further understand the inventive concept of the automatic tensioning device.

[0027] In one embodiment, if Figure 1-3 As shown, an automatic tensioning device is shown. The automatic tensioning device 1 is used for tensioning the belt 21 in the oil-water separator 2. The automatic tensioning device 1 includes a first U-shaped bracket 11 and a second U-shaped bracket 12 respectively arranged on the lower side of the oil-water separator 2. The first U-shaped bracket 11 and the second U-shaped bracket 12 are connected by a tensioning member 13; the oil-water separator 2 includes an upper roller 22 and a lower roller 23 and a belt arranged around the upper roller 22 and the lower roller 23; the rotating shaft 231 of the lower roller 23 is connected to the two side walls of the first U-shaped bracket 11 Rotational connection, specifically, the side wall of the first U-shaped bracket 11 is provided with a hole for the rotation shaft 231 to pass through, and the rotation shaft 231 is installed in the hole; the second U-shaped bracket 12 is located below the first U-shaped bracket, and the second U-shaped bracket 12 is slidingly connected to the two side walls of the oil-water separator 2; after the belt 21 becomes loose, the second U-shaped bracket 12 is moved in a direction away from the lower roller 23, and the tensioning member 13 will drive the first U-shaped bracket 11 and the lower roller 23 to move together, thereby tensioning the belt 21.

[0028] In another embodiment, if Figure 1 As shown, the automatic tensioning device 1 further includes a drive motor 14. The output end of the drive motor 14 is connected to the second U-shaped bracket 12, and the drive motor 14 drives the second U-shaped bracket 12 to move. Specifically, the drive motor 14 is fixed to the lowest end of the oil-water separator 2. When the belt 21 needs to be tensioned, the drive motor is activated, and the gears of the drive motor rotate, driving the second U-shaped bracket 12 downward. Under the action of the tensioning member 13, the first U-shaped bracket 11 and the lower tube 23 move downward together, thereby tensioning the belt 21.

[0029] In another embodiment, if Figure 1As shown, a sensor 111 is also provided inside the first U-shaped bracket 11. This sensor 111 detects whether the belt 21 is loose and sends a signal indicating this to the drive motor. Specifically, when the sensor 111 detects a loose belt, it sends this signal to the drive motor 14. Upon receiving the signal, the drive motor 14 activates and drives the second U-shaped bracket 12 downward, thereby tightening the belt. In other words, the present invention achieves automatic belt tensioning through the cooperation between the sensor 111 and the drive motor 14.

[0030] In another embodiment, if Figure 2-3 As shown, first elongated holes 24 are provided on both side walls of the oil-water separator 2 near the lower roller 23, and both ends of the rotating shaft 231 are riveted to the first elongated holes 24. Specifically, rivets are provided at both ends of the rotating shaft 131, and the rivets pass through the first elongated holes 24 to form a riveted connection.

[0031] In another embodiment, if Figure 2-3 As shown, second elongated holes 25 are provided on both side walls of the oil-water separator 2 near the second U-shaped bracket 12. Bolts 251 connect the two side walls of the second U-shaped bracket 12 to the second elongated holes 25. When the belt needs to be tightened, the bolts 251 are loosened, and the second U-shaped bracket 12 slides downward along the second elongated holes 25. After the belt is tightened, the bolts 251 are tightened to secure the second U-shaped bracket. At this point, the first U-shaped bracket 11 receives a downward pulling force from the tensioning member, causing the rotating shaft 231 to not move up and down in the first elongated hole 24, but to rotate around a fixed axis.

[0032] Preferably, two groups of bolts 251 are respectively provided in each of the second strip-shaped holes 25 .

[0033] In another embodiment, the tensioning member 13 is a spring, that is, the tensioning member is set as a spring. When the second U-shaped bracket 12 is fixed, the elastic force of the spring is applied to the first U-shaped bracket 11, so that the first U-shaped bracket 11 is always subjected to a stable downward pulling force, so that the first U-shaped bracket will not move in the vertical direction.

[0034] In another embodiment, if Figure 2As shown, an oil drain groove 16 is provided on one side wall of the oil-water separator 2. An inwardly protruding oil scraper 261 is provided at an angle at the bottom of the oil drain groove 26. Specifically, the oil scraper 261 protrudes from the end closest to the belt 21, so that one side of the oil scraper 161 contacts the belt 21. The oil adhering to the belt 21 is then scraped off by the oil scraper 261 and drained into the oil drain groove 16. Furthermore, a drive motor 27 is provided at the upper end of the oil-water separator 2 to drive the upper roller 21 to rotate. That is, in this embodiment, when the oil-water separator is working, the lower end of the oil-water separator is inserted into the liquid to be discharged, and the driving motor drives the upper roller 21 to rotate, and the upper roller 21 drives the belt 21 to rotate. When the belt 21 moves into the liquid, the oil in the liquid will adhere to the belt 21. The belt 21 continues to rotate and will bring the adhered oil to the oil drain groove 26. The scraper in the oil drain groove 26 will scrape off the oil adhered to the belt 21 and discharge it along the oil drain groove, thereby achieving the purpose of oil removal.

[0035] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
