Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separators, in particular to a floating oil-scraping oil-water separator. Background Art

[0002] The floating oil scraper oil-water separator is a device used to separate oil and water in an oil-water mixture. Its working principle is to design a special structure so that when the oil-water mixture passes through the oil-water separator, the oil will float on the water surface to form a thin film, and then the oil floating on the surface will be scraped away by a scraper or an oil scraper device, thereby achieving the purpose of oil-water separation. In the prior art, the height of most floating scrapers in contact with the water surface cannot be adjusted. When the oil concentration in the oil-water mixture changes greatly, if the height of the scraper in contact with the water surface cannot be adjusted, it is impossible to ensure that the floating oil is effectively scraped away. Moreover, the height of the scraper cannot be adjusted to the water surface, and may not be able to adapt to different water qualities or oil-water mixtures, resulting in poor separation efficiency.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, and this embodiment provides a floating oil scraper and oil-water separator. The floating oil scraper and oil-water separator includes a main body component 100 and an oil scraper component 200, and the cooperation of the two can improve the oil-water separation efficiency.

[0029] Specifically, the main component 100 includes a box body 101, a control box 102, a rotating shaft 103, a gear 104, a chain 105 and a guide plate 106. The control box 102 is fixed to one side of the box body 101, the rotating shaft 103 is arranged in the control box 102, the gear 104 is fixed to the outside of the rotating shaft 103, the chain 105 is located on the outside of the gear 104, and the guide plate 106 is fixed in the box body 101.

[0030] The box 101 is used to store the oil-water mixture, the rotating shaft 103 is connected to the external driving mechanism, and the control box 102 is used to control the driving mechanism to drive the rotating shaft 103 to rotate. When the rotating shaft 103 rotates, it will drive the gear 104 to rotate, and the gear 104 will drive the chain 105 to move, so that the chain 105 can drive the scraper to scrape the floating oil, and the guide plate 106 is used to block and guide the floating oil. This is the existing technology, and this solution will not be elaborated, and those skilled in the art can clearly understand the working principle.

[0031] Specifically, the oil scraper assembly 200 is disposed in the housing 101 , and includes an oil scraper member 201 , an adjusting member 202 and a rotating member 203 . The oil scraper member 201 is disposed in the housing 101 , the adjusting member 202 is located at one side of the oil scraper member 201 , and the rotating member 203 is disposed in the adjusting member 202 .

[0032] The oil scraper 201 is configured to scrape the floating oil on the top of the water surface. When the oil scraper 201 moves on the water surface, it can push the floating oil to move and store the floating oil at the same time, so as to avoid the situation where the amount of floating oil increases as the oil scraper 201 moves, causing excessive floating oil to move to one side or underwater, thereby improving the scraping efficiency of the floating oil. The adjusting member 202 is configured to adjust the height at which the oil scraper 201 contacts the water surface, so as to adapt to the changes in oil concentration in different oil-water mixtures. The rotating member 203 is used to drive the adjusting member 202 to move, so that the adjusting member 202 can adjust the oil scraper 201.

[0033] Example 2

[0034] Reference Figure 1~Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0035] Specifically, the oil scraper 201 includes a support plate 201a, an oil collecting box 201b and a bottom plate 201c. The support plate 201a is located at one side of the chain 105, one side of the oil collecting box 201b is fixed to the support plate 201a, and the bottom plate 201c is arranged at one side of the oil collecting box 201b.

[0036] The support plate 201a is used to support the oil collecting box 201b and drive the oil collecting box 201b to move. The side of the oil collecting box 201b that contacts the floating oil is open. When the oil collecting box 201b moves on the water surface, it will push the floating oil to move, and at the same time, excess floating oil will enter the oil collecting box 201b, so that the floating oil can be stored by the oil collecting box 201b, thereby avoiding the situation where as the floating oil increases, excessive floating oil will flow to one side or underwater, thereby resulting in low efficiency in scraping the floating oil. The bottom plate 201c is used to support the floating oil that enters the oil collecting box 201b.

[0037] Specifically, the oil scraper 201 also includes a positioning block 201d, a positioning shaft 201e and a torsion spring 201f. The positioning block 201d is fixed to one side of the oil collecting box 201b, one end of the positioning shaft 201e is fixed to the bottom plate 201c, and both ends of the torsion spring 201f are respectively fixed to the positioning shaft 201e and the positioning block 201d.

[0038] There are two positioning blocks 201d and two positioning shafts 201e, which are respectively located on both sides of the oil collecting box 201b. The positioning shaft 201e is movably connected to the positioning block 201d, and the two are used to support and position the bottom plate 201c, and at the same time, the bottom plate 201c is hinged to the bottom of the oil collecting box 201b. The torsion spring 201f applies an upward torsional force to the bottom plate 201c, so that the bottom plate 201c and the bottom of the oil collecting box 201b fit more tightly, thereby preventing the bottom plate 201c from opening downward due to the pressure of the floating oil.

[0039] Specifically, the oil scraper 201 further includes a force-bearing block 201g and a fixing block 201h. The force-bearing block 201g is fixed to one side of the bottom plate 201c, and the fixing block 201h is fixed to the top of the guide plate 106.

[0040] When the oil collecting box 201b moves to the position of the guide plate 106, the force block 201g will contact the fixed block 201h and block the force block 201g through the fixed block 201h, so that the force block 201g and the bottom plate 201c cannot move. As the oil collecting box 201b continues to move, the bottom plate 201c will open downward and flow the collected floating oil to the side of the guide plate 106, thereby completing the separation of oil and water. When the angle of the oil collecting box 201b is rotated to the upper side, the force block 201g will be separated from the fixed block 201h, and the bottom plate 201c can be reset.

[0041] Specifically, the adjusting member 202 includes a supporting frame 202a, a movable plate 202b and a first spring 202c. One side of the supporting frame 202a is fixed to the chain 105. The movable plate 202b is located in the supporting frame 202a. Both ends of the first spring 202c are respectively fixed to the movable plate 202b and the supporting plate 201a.

[0042] The support plate 201a is movably connected to the support frame 202a. There are multiple first springs 202c, which are evenly distributed in a straight line on one side of the movable plate 202b. The movable plate 202b is connected to the support plate 201a by the first spring 202c, so that when the movable plate 202b moves, it can drive the support plate 201a to move, and drive the oil collecting box 201b to move through the support plate 201a, so that the height of the oil collecting box 201b in contact with the water surface can be adjusted, thereby being able to adapt to changes in oil concentration in different oil-water mixtures.

[0043] And when the oil collecting box 201b moves downward more on the water surface, when the oil collecting box 201b moves to the position of the guide plate 106, it may be restricted by the guide plate 106 and cannot move. At this time, the support plate 201a will move upward and compress the first spring 202c, so that when the oil collecting box 201b is restricted by the guide plate 106, its height will return to its initial position, so that its movement will not be hindered.

[0044] Specifically, the adjusting member 202 further includes a positioning column 202d, one end of which is fixed to the inner wall of the supporting frame 202a, and the positioning column 202d is movably connected to the movable plate 202b.

[0045] The positioning column 202d is used to support and position the movable plate 202b to prevent it from tilting when moving.

[0046] Example 3

[0047] Reference Figure 1~Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0048] Specifically, there are a plurality of positioning posts 202d, which are evenly distributed in a straight line within the support frame 202a.

[0049] Specifically, the rotating member 203 includes a rotating column 203a, a fixed shaft 203b and a rotating rod 203c. The rotating column 203a is rotatably connected to the support frame 202a, the fixed shaft 203b is fixed in the movable plate 202b, one side of the rotating rod 203c is fixed to the rotating column 203a, and a spiral groove 203a-1 is opened on the rotating column 203a, and the fixed shaft 203b slides in the spiral groove 203a-1.

[0050] The rotating column 203a is movably connected with the movable plate 202b. When the rotating rod 203c rotates, it will drive the rotating column 203a to rotate. At this time, the fixed shaft 203b will move in the spiral groove 203a-1. The cooperation of the two can drive the movable plate 202b to move, so that the supporting plate 201a and the oil collecting box 201b can be driven to move through the movable plate 202b.

[0051] Specifically, the rotating member 203 also includes a movable block 203d and a connecting shaft 203e. The movable block 203d is located on one side of the rotating rod 203c. One end of the connecting shaft 203e is fixed to the movable block 203d. A sliding groove 203c-1 is provided on the rotating rod 203c, and the connecting shaft 203e slides in the sliding groove 203c-1.

[0052] When the movable block 203d moves, it will drive the connecting shaft 203e to slide in the sliding groove 203c-1, and the cooperation between the two can drive the rotating rod 203c to rotate.

[0053] Specifically, the rotating member 203 further includes a threaded rod 203f and a rotating handle 203g. The threaded rod 203f is rotatably connected to the support frame 202a, and one end of the rotating handle 203g is connected to the threaded rod 203f.

[0054] A threaded hole is provided in the movable block 203d, and the threaded rod 203f is threadedly connected to the threaded hole. When the threaded rod 203f rotates, the movable block 203d is driven to move through the cooperation of the threaded hole, so that the movable block 203d can drive the connecting shaft 203e to move, and the threaded rod 203f can be easily rotated through the turning handle 203g.

[0055] During use, when the oil-water mixture is injected into the box 101 and there is floating oil on the top of the water surface, the driving mechanism is started to drive the rotating shaft 103 to rotate. When the rotating shaft 103 rotates, it will drive the gear 104 to rotate, and the gear 104 will drive the chain 105 to move. When the chain 105 moves, it will drive the support frame 202a and the support plate 201a to move, and drive the oil collecting box 201b to move through the support plate 201a.

[0056] When the oil collecting box 201b moves on the water surface, it will push the floating oil to move, and at the same time, excess floating oil will enter the oil collecting box 201b, so that the floating oil can be stored by the oil collecting box 201b, thereby avoiding the situation where as the floating oil increases, excessive floating oil will flow to one side or underwater, thereby resulting in low efficiency in scraping off the floating oil.

[0057] When the oil collecting box 201b moves to the position of the guide plate 106, the force block 201g will contact the fixed block 201h and block the force block 201g through the fixed block 201h, so that the force block 201g and the bottom plate 201c cannot move. As the oil collecting box 201b continues to move, the bottom plate 201c will open downward and flow the collected floating oil to the side of the guide plate 106, thereby completing the separation of oil and water. When the angle of the oil collecting box 201b is rotated to the upper side, the force block 201g will separate from the fixed block 201h. At this time, the torsion spring 201f applies an upward torsional force to the bottom plate 201c, so that the bottom plate 201c fits with the bottom of the oil collecting box 201b.

[0058] When the oil concentration in different oil-water mixtures changes, causing the floating oil on the top of the water surface to increase or decrease, the rotating handle 203g is rotated to drive the threaded rod 203f to rotate, and the movable block 203d is driven to move through the cooperation of the threaded hole. When the movable block 203d moves, it will drive the connecting shaft 203e to slide in the slide groove 203c-1. Through the cooperation of the two, the rotating rod 203c can be driven to rotate. When the rotating rod 203c rotates, it will drive the rotating column 203a to rotate. At this time, the fixed shaft 203b will move in the spiral groove 203a-1. Through the cooperation of the two, the movable plate 202b can be driven to move, so that the support plate 201a and the oil collecting box 201b can be driven to move through the movable plate 202b, so that the height of the oil collecting box 201b in contact with the water surface can be adjusted, thereby being able to adapt to the changes in oil concentration in different oil-water mixtures.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
