Description

Technical Field

[0001] This utility model relates to the field of petroleum extraction technology, and more specifically, to a device for treating and recovering petroleum drilling waste fluid. Background Technology

[0002] Oil drilling and production processes generate a large amount of complex waste fluids, mainly including drilling mud, fracturing flowback fluid, and produced water. These waste fluids contain oil, suspended solids, heavy metals, chemical additives, dissolved salts, and even radioactive substances. Direct discharge or improper disposal will cause serious pollution to soil, water bodies, and the ecological environment. Oil drilling waste fluid treatment and recovery devices are comprehensive systems designed to solve this key environmental and resource problem. Their main goal is to remove harmful pollutants from the waste fluids so that the treated water meets the national or local discharge standards or reinjection formation standards, efficiently recover crude oil and reusable water resources from the waste fluids, and reduce water consumption and wastewater discharge. Because the waste fluids contain a large number of large particulate impurities, it is necessary to perform pretreatment operations for recovery.

[0003] In related technologies, during the use of waste liquid treatment and recycling devices, large particulate impurities in the waste liquid are generally filtered and pretreated by means of a grid or filter screen before use.

[0004] However, in the current use of waste liquid treatment and recycling devices, since the grids and filters are generally set vertically, as large particles of impurities in the pre-treated waste liquid are filtered, these impurities will remain on the top of the filter or grid, causing pre-treatment blockage. This requires staff to conduct regular inspections, cleaning, and maintenance, affecting the smoothness and convenience of impurity handling in the waste liquid treatment and recycling device.

[0005] To overcome the above deficiencies, this utility model provides an oil drilling waste fluid treatment and recovery device that overcomes or at least partially solves the above technical problems.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: an oil drilling waste fluid treatment and recovery device, including a treatment and recovery tank 1 and an inclined impurity removal mechanism. The top of the treatment and recovery tank 1 is equipped with an inlet hopper 2, and the bottom right side of the treatment and recovery tank 1 is equipped with a drain pipe 3. While filtering and removing large particulate impurities from the waste fluid entering the treatment and recovery tank 1, the device can also tilt and guide the filtered impurities to be discharged from the treatment and recovery tank 1, thus avoiding the blockage of impurity pretreatment during the operation of the treatment and recovery tank 1. Therefore, it improves the smoothness and convenience of impurity treatment in the treatment and recovery tank 1.

[0031] Reference Figures 1-4 In a preferred embodiment, the tilting impurity removal mechanism includes a tilting frame 4, which is movably connected to the left side of the processing and recovery tank 1. A vertical frame 5 is movably connected to the left side of the tilting frame 4 via a hinge support. An impurity discharge port 6 is located at the top of the left side of the processing and recovery tank 1. Filter screens 7 are fixedly connected to the tops of both the tilting frame 4 and the vertical frame 5. The tilting connection mechanism is movably connected to the right side of the tilting frame 4 via a hinge support. When external waste liquid is added into the processing and recovery tank 1 through the inlet hopper 2, the tilting frame 4, in conjunction with the vertical frame 5 and the filter screen 7, forms a tilting impurity filtering medium at the bottom of the inlet hopper 2. The waste liquid first contacts the filter screen 7 at the top of the tilting frame 4. At this time, the filter screen 7 filters the impurities in the waste liquid. The filtered waste liquid continues to move downwards into the processing and recovery tank 1 under its own gravity. The filtered impurities, affected by the slope of the inclined frame 4 and their own gravity, move to the left along the top filter screen 7 of the inclined frame 4 and are discharged from the treatment and recycling box 1 through the impurity discharge port 6. The inclined connection mechanism includes a connecting plate 8, a connecting port 9, and a connecting seat 10. The connecting plate 8 is movably connected to the right side of the inclined frame 4 through a hinge support. The top of the connecting plate 8 contacts the top of the inner wall of the treatment and recycling box 1. The connecting port 9 is opened on the top of the connecting plate 8. The connecting seat 10 is movably connected inside the connecting port 9. This allows for adjustment and anti-displacement connection between the inclined frame 4 and the treatment and recycling box 1, so that the user can adjust the slope of the inclined frame 4. This avoids the inability to adjust the slope of the inclined frame 4 due to its position during operation, thus improving the connection effect and adjustment smoothness between the inclined frame 4 and the treatment and recycling box 1.

[0032] Reference Figures 2-4In a preferred embodiment, by providing threaded grooves 11 at each of the four corners inside the connecting seat 10, and threaded bolts 12 that are threaded to the processing and recycling box 1 inside the threaded grooves 11, the connection between the connecting seat 10 and the processing and recycling box 1 can be stably maintained, avoiding situations where the connecting seat 10 is difficult to install and connect to the processing and recycling box 1 or is misaligned during use. Therefore, the working stability and installation convenience of the connecting column are improved. The inner walls of the inclined frame 4 and the vertical frame 5 are fixedly connected with support rods 13. The top of the support rods 13 contacts the bottom of the filter screen 7, which can provide stable support between the filter screen 7 and the inclined frame 4 and the vertical frame 5, avoiding deformation of the filter screen 7 under stress during operation. Therefore, the working stability of the filter screen 7 is improved.

[0033] Reference Figures 2-4 In a preferred embodiment, a lifting frame 14 is fixedly connected to the left side of the recycling bin 1, located at the bottom of the discharge port 6. A lifting plate 15 is movably connected inside the lifting frame 14, and the top of the lifting plate 15 is fixedly connected to the bottom of the vertical frame 5. This can provide stable support for the adjusted vertical frame 5 and the inclined frame 4, thus improving the stability of the vertical frame 5 and the inclined frame 4 during operation. A positioning cylinder 16 is fixedly connected to the front side of the lifting frame 14, and a positioning column 17 is movably connected inside the positioning cylinder 16. A positioning groove 18 communicating with the positioning cylinder 16 is opened on the front side of the lifting plate 15, which can be used for insertion and positioning between the lifting plate 15 and the lifting frame 14, avoiding the difficulty in positioning the lifting plate 15 during use, thus improving the convenience of positioning the support plate.

[0034] Reference Figures 2-4 In a preferred embodiment, a magnetic strip 19 is embedded and connected to the top of the inner wall of the positioning cylinder 16, and a magnetic strip 20 connected to the magnetic strip 19 is embedded and connected to the top of the positioning post 17. This allows for magnetic positioning between the positioning post 17 and the positioning cylinder 16, preventing the positioning post 17 from detaching from the positioning groove 18 during use. This improves the stability of the positioning post 17's insertion and positioning. A discharge hopper 21 is fixedly connected to the left side of the recycling bin 1. The discharge hopper 21 is located at the bottom of the lifting plate 15 and can receive and guide the impurities discharged from the discharge port 6, thus improving the discharge guiding effect of the discharge port 6.

[0035] Specifically, the working process or working principle of this oil drilling waste treatment and recovery device is as follows: When using the inclined frame 4 for the first time to remove impurities, based on the actual needs of pre-treatment of large particulate impurities in the oil drilling waste treatment and recovery, the handheld lifting plate 15 moves upward inside the lifting frame 14, applying an upward thrust to the vertical frame 5. As the vertical frame 5 moves upward, the inclined frame 4 is affected by the upward thrust of the vertical frame 5, causing the slope of the inclined frame 4 to change and pushing the connecting plate 8 to move to the right. At this time, the connecting seat 10 moves inside the connecting port 9 to cooperate with the connecting plate 8, performing translational connection and limit work between the inclined frame 4 and the treatment and recovery box 1 during the slope adjustment process. Simultaneously, the bolt 12 cooperates with the screw groove 11 to stabilize the connection between the connecting seat 10 and the treatment and recovery box 1. During this process, the positioning groove 18 moves inside the lifting frame 14 following the lifting plate 15. After the slope of the inclined frame 4 is adjusted, the handheld positioning column 17 moves backward, penetrating the lifting frame 14 and entering the positioning groove 18. Inside, the positioning column 17, in conjunction with the positioning groove 18, performs the insertion and positioning work between the lifting plate 15 and the lifting frame 14, causing the lifting plate 15 to stabilize the position of the vertical frame 5 and the inclined frame 4. At this time, the magnetic strip 19, in conjunction with the magnetic suction strip 20, performs the insertion, positioning, magnetic suction, and stabilization work for the positioning column 17. When external oil drilling waste fluid is added into the treatment and recovery tank 1 through the inlet hopper 2, the waste fluid first contacts the filter screen 7 at the top of the inclined frame 4. At this time, the filter screen 7 filters the impurities in the waste fluid. The filtered waste fluid continues to move downward into the treatment and recovery tank 1 under the influence of its own gravity. The filtered impurities, affected by the slope of the inclined frame 4 and its own gravity, move to the left along the filter screen 7 at the top of the inclined frame 4, pass through the filter screen 7 at the top of the vertical frame 5, and are discharged from the treatment and recovery tank 1 through the discharge port 6. At this time, the support rod 13 provides support and reinforcement between the filter screen 7, the inclined frame 4, and the vertical frame 5. At the same time, the discharge hopper 21 receives and guides the impurities discharged through the discharge port 6.

[0036] It should be noted that the processing and recycling box 1, the liquid inlet hopper 2 and the liquid outlet pipe 3 are all existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
