Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a device for recovering floating oil from oil well repair wastewater. Background Technology

[0002] Oil well maintenance generates a large amount of wastewater containing oil. Since oil is insoluble in water, it floats on the surface of the wastewater. Direct discharge not only pollutes the environment, but the floating oil can also be recycled and reused. As oil is a non-renewable resource, its recycling is essential.

[0003] Chinese patent document CN219991239U discloses an oil well workover wastewater oil recovery device. This device includes a wastewater tank, a pump mounted on top of the tank, a discharge pipe connected to one side of the tank, a movable component above the tank, an adjusting component above the movable component, and a suction component below the adjusting component. The pump's suction end is connected to a suction pipe. The movable component includes a motor mounted on top of the wastewater tank, with a lead screw fixedly connected to the motor's output end. A threaded sleeve is threaded onto the outer side of the lead screw. This invention solves the problem of existing devices using a float suction device to extract floating oil, which is inefficient due to its fixed-point suction and the large amount of wastewater it draws in during extraction, resulting in a large workload for subsequent oil-water separation.

[0004] The existing technology has the following problems:

[0005] The device directly uses a lead screw to drive the suction component. However, the lead screw is exposed to the air. Since the device is designed to treat sewage, the surrounding air is relatively humid. As the lead screw is a relatively precise transmission component, it is easily affected by the surrounding environment, which may lead to the component jamming. Utility Model Content

[0006] This invention provides a device for recovering floating oil from oil well workover wastewater, in order to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] An oil well repair wastewater oil recovery device includes a treatment tank. A drain pipe is fixedly connected to the left side of the treatment tank near the bottom, and a water inlet pipe is fixedly connected to the right side of the treatment tank near the bottom. Two limiting plates distributed on the left and right sides are fixedly connected to the front and rear sides of the inner side of the treatment tank near the left and right sides. A recovery mechanism is movably sleeved on the inner side of the treatment tank, and a moving mechanism is rotatably connected to the front and rear sides of the treatment tank.

[0009] The recycling mechanism includes a collection box, and the moving mechanism includes a motor. The lower side of the motor is fixedly connected to a protrusion near the bottom of the front and rear sides of the treatment pool. A first gear is fixedly connected to the output end of the motor. Two winding discs distributed to the left and right are rotatably connected to the center of the front and rear sides of the treatment pool. A second gear is fixedly connected to the side of each winding disc away from the treatment pool. A traction rope is wound around the inner side of each winding disc. A sliding frame is fixedly connected to the end of the traction rope away from the winding disc. The side of the sliding frame near the collection box is slidably connected to the front and rear sides of the treatment pool. Two rollers distributed to the left and right are fixedly connected to the front and rear sides of the collection box. The outer side of the rollers is slidably connected to the inner side of the sliding frame.

[0010] Preferably, the left and right sides of the collection box are rotatably connected to two sealing plates distributed on the left and right sides. The upper side of the collection box is fixedly connected to two centrally symmetrically distributed first telescopic rods. Each of the two sealing plates is fixedly connected to a guide rod on the side near the first telescopic rod. Each of the two first telescopic rods is fixedly connected to a guide sleeve at its movable end. The inner side of the guide sleeve is movably sleeved on the outer side of the first telescopic rod.

[0011] Preferably, two suction frames distributed on the left and right are movably sleeved on the inner side of the upper wall of the collection box, and two second telescopic rods distributed in front and behind are fixedly connected to the upper side of each of the two suction frames. The lower side of the second telescopic rods is fixedly connected to the left and right sides of the upper side of the collection box.

[0012] Preferably, the inner lower surface of the collection box is shaped like a "︹" and two guide grooves are provided on the front and rear sides of the treatment pool, with the outer side of the roller slidably connected to the inner side of the guide groove.

[0014] Preferably, the roller is conical in shape.

[0015] Preferably, the portion of the traction rope near the sliding frame is made of an elastic material.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides an oil well repair wastewater floating oil recovery device, which adopts the cooperation of a recovery mechanism, a moving mechanism, a motor, a first gear, a winding disc, a traction rope, a second gear, a sliding frame and rollers. The motor drives the two winding discs to rotate, so that the traction rope pulls the recovery mechanism to move left and right.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown, an oil well repair wastewater oil recovery device includes a treatment tank 1. A drain pipe 2 is fixedly connected to the left side of the treatment tank 1 near the bottom. A water inlet pipe 3 is fixedly connected to the right side of the treatment tank 1 near the bottom. Two limiting plates 4 are fixedly connected to the front and rear sides of the inner side of the treatment tank 1 near the left and right sides. A recovery mechanism 5 is movably sleeved on the inner side of the treatment tank 1. A moving mechanism 6 is rotatably connected to the front and rear sides of the treatment tank 1.

[0027] The recycling mechanism 5 includes a collection box 51, and the moving mechanism 6 includes a motor 61. The lower side of the motor 61 is fixedly connected to a protrusion near the bottom of the front and rear sides of the treatment pool 1. The output end of the motor 61 is fixedly connected to a first gear 62. Two winding discs 63 are rotatably connected to the middle of the front and rear sides of the treatment pool 1. A second gear 65 is fixedly connected to the side of each winding disc 63 away from the treatment pool 1. A traction rope 64 is wound around the inner side of each winding disc 63. A sliding frame 66 is fixedly connected to the end of the traction rope 64 away from the winding disc 63. The side of the sliding frame 66 near the collection box 51 is slidably connected to the front and rear sides of the treatment pool 1. Two rollers 67 are fixedly connected to the front and rear sides of the collection box 51. The outer side of the rollers 67 is slidably connected to the inner side of the sliding frame 66.

[0028] It should be noted that the limiting plate 4 is used to limit the liquid level range of sewage in the treatment tank 1. The motor 61 drives the first gear 62 to rotate. The first gear 62 meshes with the second gear 65, so that the two winding discs 63 rotate synchronously in the same direction. When the winding discs 63 rotate, the traction rope 64 is tightened or extended on the winding discs 63, so that the traction rope 64 pulls the sliding frame 66 to move left and right, which in turn pushes the roller 67, so that the collection box 51 moves left and right.

[0029] like Figure 4 As shown, two sealing plates 52 are rotatably connected to the left and right sides of the collection box 51. Two centrally symmetrically distributed first telescopic rods 53 are fixedly connected to the upper side of the collection box 51 near the left and right sides. Guide rods 54 are fixedly connected to the side of each sealing plate 52 near the first telescopic rods 53. Guide sleeves 55 are fixedly connected to the movable ends of the two first telescopic rods 53. The inner side of the guide sleeve 55 is movably sleeved on the outer side of the first telescopic rod 53.

[0030] It should be noted that the first telescopic rod 53 can control its own length, causing the first telescopic rod 53 to drive the guide sleeve 55 to move back and forth. The guide rod 54 is provided with a spiral groove, so that the sealing plate 52 rotates when the guide sleeve 55 moves back and forth. When the sealing plate 52 rotates, it opens or closes the left and right sides of the collection box 51.

[0031] like Figure 4As shown, two suction brackets 56 distributed on the left and right are movably sleeved on the inner side of the upper wall of the collection box 51. Two second telescopic rods 57 distributed in front and behind are fixedly connected to the upper side of each suction bracket 56. The lower side of the second telescopic rods 57 is fixedly connected to the left and right sides of the upper side of the collection box 51.

[0032] It should be noted that the second telescopic rod 57 can control its own length, so that the second telescopic rod 57 can drive the suction frame 56 to move up and down. When the suction frame 56 moves up and down, the liquid inlet end on the lower side of the suction frame 56 moves up and down.

[0033] like Figure 3 , Figure 5 As shown, the inner lower surface of the collection box 51 is shaped like a "︹" and two guide grooves 69 distributed in the front and back are provided on the front and back sides of the treatment pool 1. The outer side of the roller 67 is slidably connected to the inner side of the guide groove 69.

[0034] It should be noted that when the collection box 51 moves left and right, water and floating oil are collected together inside the collection box 51. Since the floating oil is on the surface of the water, the heavier water is at the bottom. The water can be discharged from the drain hole at the bottom of the sealing plate 52. The shape of the bottom of the collection box 51 can collect as much floating oil as possible and prevent the floating oil from being discharged from the perforation. When the collection box 51 is moved to the left and right sides, due to the presence of the guide groove 69, one side of the collection box 51 is tilted up, so that the suction frame 56 can completely remove the floating oil when extracting it. This avoids the problem of insufficient floating oil in the collection box 51, which would make it difficult to extract. The shape of the bottom of the collection box 51 causes a small amount of floating oil to gather when the collection box 51 is tilted up on one side, making it easy to extract.

[0035] like Figure 3 As shown, two blower heads 68 are fixedly connected to the left and right sides of the sliding frame 66.

[0036] It should be noted that the blower head 68 blows air into the treatment tank 1 through the guide groove 69, causing the floating oil near the front and rear sides of the inner side of the treatment tank 1 to move towards the middle.

[0037] like Figure 3 As shown, roller 67 is conical in shape.

[0038] It should be noted that the shape of the roller 67 allows the front and rear sides of the collection box 51 to not be in close contact with the inner front and rear sides of the treatment pool 1. The roller 67 can restrict the collection box 51 from moving back and forth by its own shape.

[0039] like Figure 3 As shown, the portion of the traction rope 64 near the sliding frame 66 is made of an elastic material.

[0040] It should be noted that the use of elastic materials allows the traction rope 64 to remain taut even after thermal expansion and contraction, preventing the traction rope 64 from becoming slack due to the surrounding environment.

[0041] The working principle of this utility model is as follows: First, the motor 61 drives the first gear 62 to rotate. The first gear 62 meshes with the second gear 65, causing the two winding discs 63 to rotate synchronously and in the same direction. When the winding discs 63 rotate, the traction rope 64 is tightened or extended on the winding discs 63, causing the traction rope 64 to pull the sliding frame 66 to move left and right. In turn, the sliding frame 66 pushes the roller 67, causing the collection box 51 to move left and right. The shape of the roller 67 ensures that the front and rear sides of the collection box 51 do not need to be tightly attached to the inner front and rear sides of the treatment pool 1. The roller 67 can restrict the collection box 51 from moving back and forth by its own shape. Some elastic materials can... This design ensures that the traction rope 64 remains taut even after thermal expansion and contraction, preventing it from slack due to environmental factors. The motor 61 drives the two winding discs 63 to rotate, causing the traction rope 64 to pull the recovery mechanism 5 left and right. This reduces the precision required for the overall transmission and minimizes the impact of environmental influences on the transmission, allowing the device to operate stably for extended periods. Finally, the first telescopic rod 53 can control its length, causing it to move the guide sleeve 55 back and forth. The guide rod 54 has a spiral groove, allowing the guide sleeve 55 to move back and forth. When the sealing plate 52 moves back and forth, it rotates, opening or closing the left and right sides of the collection box 51. The second telescopic rod 57 can control its own length, causing it to drive the suction frame 56 to move up and down. When the suction frame 56 moves up and down, the liquid inlet end on the lower side of the suction frame 56 moves up and down. When the collection box 51 moves left and right, water and floating oil are collected together inside the collection box 51. Because the floating oil is on the water surface, the heavier water is at the bottom. The water can be discharged from the leakage hole at the bottom of the sealing plate 52. The shape of the bottom of the collection box 51 can collect as much floating oil as possible and prevent the floating oil from being discharged from the perforation. When collecting... When the collection box 51 is moved to the left and right sides, the presence of the guide groove 69 causes one side of the collection box 51 to tilt up, allowing the suction frame 56 to remove the floating oil as completely as possible. This avoids the problem of insufficient floating oil in the collection box 51, which would make it difficult to extract. The shape of the bottom of the collection box 51 causes a small amount of floating oil to gather when the collection box 51 tilts up on one side, making it easy to extract. The two sealing plates 52 seal one side of the collection box 51, allowing the floating oil to be collected into the collection box 51. This makes it easier for the suction frame 56 to extract the floating oil, avoiding direct suction which would cause the floating oil to be more dispersed and contain a large amount of water.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
