Abstract
Description
Technical Field
[0001] This utility model relates to the field of oilfield development technology, and in particular to a wastewater reinjection device for oilfield development with a cleaning structure. Background Technology
[0002] In the field of oilfield development technology, water injection is an important means of maintaining reservoir pressure and facilitating stable oil production. In order to save resources and costs, wastewater reinjection devices are often used to treat the wastewater generated during oilfield development and reinject it into the oilfield, thereby facilitating subsequent operations. In an oilfield development wastewater reinjection device with announcement number CN221141255U, a treatment box is included. The upper part of the treatment box is equipped with a filter screen, and the left and right sides of the filter screen are connected to a feeding plate. The other end of the feeding plate is connected to the inner wall of the treatment box. The upper and lower sides of the filter screen are respectively equipped with a cleaning mechanism and a support. A mixing rod is movably inserted into the middle of the top of the support. The mixing rod is equipped with two sets of mixing plates, and the upper and lower ends of the mixing rod are respectively connected to a passive bevel gear and a first bearing. The passive bevel gear is equipped with a rotating mechanism. The lower left side and the bottom right side of the treatment box are respectively fixedly connected to a conveying pipe and a drain pipe. The upper left and right sides of the treatment box are respectively fixedly connected to a waste discharge pipe. The top middle of the treatment box is fixedly inserted with a liquid inlet pipe. By cleaning the filter screen during the wastewater purification process, it is possible to effectively avoid the filter screen from becoming clogged after long-term use. However, the aforementioned wastewater reinjection device for oilfield development still has the following drawbacks: In use, the existing technology involves starting a motor, which drives a driven rod and an active bevel gear to rotate a passive bevel gear. This, in turn, drives a mixing plate to rotate via a mixing rod, facilitating the mixing of the purifying agent and the filtered wastewater for further purification. However, in actual use, the fixed mixing range of the mixing plate prevents the wastewater from mixing well with the purifying agent, thus reducing the efficiency of wastewater treatment.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] Please see Figures 1-5 An embodiment of this utility model is provided: a wastewater reinjection device for oilfield development with a cleaning structure, including a treatment tank 1, a sewage outlet 2, a drainage outlet 4, a feed inlet 6, and a water inlet 7. Sewage outlets 2 are fixed on both sides of the treatment tank 1. A drainage outlet 4 is provided on one side of the treatment tank 1 at the bottom of one sewage outlet 2, and a feed inlet 6 is provided on one side of the treatment tank 1 at the bottom of the other sewage outlet 2. A water inlet 7 is fixedly inserted into one side of the top of the treatment tank 1. A support frame 9 is welded to the other side of the top of the treatment tank 1, and an air blowing mechanism 8 is provided at the top of the support frame 9. The blowing mechanism 8 includes a blower 802, which is located at the top of the support frame 9. A conduit 801 is fixed on one side of the blower 802, and an adjusting shaft 803 is provided on the other side of the blower 802. A driven pulley 804 is fixed on the outer side of the adjusting shaft 803. A connecting belt 805 is provided on the outer side of the driven pulley 804, and a driving pulley 806 is provided on one side of the connecting belt 805. The driving pulley 806 is fixedly connected to the adjusting rod 11. The cross-section of the conduit 801 is annular, one end of the conduit 801 extends into the interior of the drive shaft 501, and the conduit 801 and the drive shaft 501 are rotatably connected. One end of the adjusting shaft 803 extends into the interior of the blower 802, and a rotating impeller is provided inside the blower 802. One end of the adjusting shaft 803 is fixedly connected to the rotating impeller inside the blower 802. Specifically, such as Figure 1 , Figure 3, Figure 5 As shown, during use, the adjusting motor 10 is started to drive the adjusting rod 11 to rotate, and the adjusting shaft 803 is driven to rotate under the action of the driving pulley 806, the connecting belt 805 and the driven pulley 804. This causes the blower 802 to generate suction force, which introduces outside air into the inside of the duct 801. Under the action of the driving shaft 501, the air is sprayed out through the through hole 502, thereby making the purifying agent and sewage inside the treatment tank 1 fully mixed, thus improving its practicality. An adjustment motor 10 is fixed to one side of the support frame 9, and an adjustment rod 11 is fixed to one side of the adjustment motor 10. An adjustment mechanism 5 is provided on one side of the adjustment rod 11. The adjustment mechanism 5 includes a drive shaft 501, which is located inside the processing tank 1. Stirring rods 503 are evenly fixed on both sides of the drive shaft 501, and through holes 502 are provided on both sides of the stirring rods 503. A drive bevel gear 507 is fixed at one end of the drive shaft 501 extending to the outside of the processing tank 1. A fixed bevel gear 509 meshes with one side of the drive bevel gear 507, and a driven bevel gear 508 meshes with one side of the fixed bevel gear 509. A driven shaft 506 passes through the interior of the driven bevel gear 508. An adjustment block 505 is fixed at one end of the driven shaft 506 extending into the interior of the processing tank 1. Four cleaning plates 504 are welded to the outside of the adjustment block 505. The cross sections of the drive shaft 501, the stirring rod 503, and the driven shaft 506 are all annular, and the drive shaft 501, the stirring rod 503, and the driven shaft 506 are all hollow internal structures. Multiple sets of through holes 502 are provided, and each set of through holes 502 has multiple through holes 502, and each set of through holes 502 is distributed at equal intervals. The interior of the treatment tank 1 is equipped with a filter screen 3; Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, during use, the adjusting motor 10 is started to drive the adjusting rod 11 to rotate. Under the action of the fixed bevel gear 509, the driving bevel gear 507 is driven to rotate, and under the action of the driving shaft 501, the stirring rod 503 is driven to rotate synchronously. This facilitates the stirring of the sewage inside the treatment tank 1, so that the sewage and the purifying agent are mixed. On the other hand, under the action of the driven bevel gear 508 and the driven shaft 506, the adjusting block 505 is driven to rotate, so that the cleaning plate 504 can clean the filter screen 3 to avoid the filter screen 3 from becoming clogged.
[0017] Working Principle: In use, wastewater from oilfield development is first introduced into the treatment tank 1 through the inlet 7. It then passes through the filter screen 3, where impurities are retained. A purifying agent is then introduced into the treatment tank 1 through the feed inlet 6. Simultaneously, the regulating motor 10 is activated, causing the regulating rod 11 to rotate. This rotation of the regulating rod 11 drives the fixed bevel gear 509 to rotate, which in turn drives the driving bevel gear 507 to rotate, thus causing the drive shaft 501 to rotate synchronously. The rotating motion drives the stirring rod 503 to rotate, allowing the wastewater and purifying agent inside the treatment tank 1 to be fully mixed. Simultaneously, the fixed bevel gear 509 rotates, driving the driven bevel gear 508 to rotate synchronously, which in turn causes the driven shaft 506 to rotate, leading to the adjustment block 505 rotating. This rotation of the adjustment block 505, in turn, drives the cleaning plate 504 to rotate synchronously. This process facilitates cleaning of the filter screen 3, preventing clogging and improving its filtration efficiency. Then, by starting the regulating motor 10, the regulating rod 11 is driven to rotate. Simultaneously, the regulating rod 11 drives the drive pulley 806 to rotate synchronously. The drive pulley 806, in turn, drives the connecting belt 805 to rotate synchronously, which in turn drives the driven pulley 804 to rotate synchronously. This, in turn, drives the regulating shaft 803 to rotate synchronously. Since the regulating shaft 803 is fixedly connected to the rotating impeller inside the blower 802, the rotation of the regulating shaft 803 simultaneously drives the rotating impeller to rotate synchronously. This causes the blower 802 to generate suction force, which in turn draws outside air into the conduit 801 and through the drive shaft 501 into the stirring rod 503, and then sprays it out through the through hole 502. This ensures that the wastewater and purifying agent inside the treatment tank 1 are fully mixed, allowing the purifying agent to be evenly distributed in the wastewater, thereby improving the wastewater treatment effect. The filtered and purified water can then be reinjected into the oil field through the drain outlet 4, thus achieving the goal of saving resources and costs.
