Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, and in particular to an oil draining device for oil extraction. Background Technology

[0002] An oil drain is a hydraulic control element commonly used in hydraulic systems and well workover operations in oilfield pumping wells. Its main function is to protect the normal operation of the hydraulic system by controlling flow and pressure, and to drain sludge and wastewater from the pump and tubing during well workover. The working principle of the oil drain is based on controlling the flow of liquid to achieve the purpose of controlling pressure and flow. In hydraulic systems, oil drains are usually installed at the outlet of hydraulic cylinders or hydraulic motors.

[0003] After the existing oil drainer is installed, it needs a filter screen to filter the crude oil during operation. However, after long-term use, the filter screen will be blocked by solid particles, which will affect the subsequent filtration work. Therefore, it is necessary to clean the solid particles. At the same time, the staff needs to clean the inside of the oil drainer regularly, which requires disassembly, which is quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as filter screen blockage and internal cleaning of the oil drainer, and to propose an oil drainer for oil extraction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An oil drainer for oil extraction includes: a drainer body, a cleaning assembly installed inside the drainer body, an oil outlet pipe on the drainer body, multiple sliding grooves inside the drainer body, a filter screen slidably connected to the multiple sliding grooves, a rotary motor fixedly installed on the drainer body, a rotating rod fixedly connected to the motor shaft of the rotary motor, a bevel gear fixedly installed at one end of the rotating rod, a cross rod fixedly installed on the drainer body, a rotating rod rotatably connected to the cross rod, a bevel gear fixedly installed at the lower end of the rotating rod, the bevel gear meshing with the bevel gear, and two symmetrical cleaning blocks fixedly installed at the upper end of the rotating rod, each of the two cleaning blocks being equipped with a vibration assembly.

[0007] Preferably, the vibration assembly includes a sliding opening on the cleaning block, a lifting block is slidably connected in the sliding opening, springs are fixedly installed at both ends of the lifting block, the other ends of the two springs are fixedly connected to the cleaning block, and multiple protrusions and recesses are fixedly installed on the upper surface of the cross rod.

[0008] Preferably, the cleaning assembly includes a second rotary motor fixedly connected to the outer wall of the oil drainer body. The motor shaft of the second rotary motor passes through the oil drainer body and is fixedly mounted with a rotating rod. A third bevel gear is fixedly mounted on the rotating rod. Two mutually symmetrical threaded rods are rotatably connected inside the oil drainer body. A fourth bevel gear is fixedly mounted at one end of each of the two threaded rods. Both fourth bevel gears mesh with the third bevel gear. A cleaning block is threadedly connected to each of the two threaded rods.

[0009] Preferably, the upper ends of the plurality of protrusions and concave blocks are all circular surfaces.

[0010] Preferably, both cleaning blocks are made of corrosion-resistant material.

[0011] Preferably, a spiral blade is fixedly installed at the other end of the rotating rod, and the spiral blade is rotatably installed inside the oil outlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the rotation of bevel gear one and bevel gear two driven by the rotating motor one causes the cleaning block to sweep away solids from the filter screen, thereby preventing solid particles from clogging the filter screen. At the same time, the vibration component can vibrate the filter screen, thereby accelerating the fixing and falling off. Meanwhile, the movement of the cleaning block driven by the threaded rod in the cleaning component can easily clean the inside, reducing the labor of the workers. Attached Figure Description

[0018] Reference Figure 1-4An oil drain device for oil extraction includes:

[0019] The oil drainer body 1 has a cleaning assembly installed inside it. The cleaning assembly includes a second rotary motor 15 fixedly connected to the outer wall of the oil drainer body 1. The second rotary motor 15 is existing technology and can rotate an object connected to the motor shaft of the second rotary motor 15. The motor shaft of the second rotary motor 15 passes through the oil drainer body 1 and a rotating rod 16 is fixedly installed thereon. A spiral blade 21 is fixedly installed at the other end of the rotating rod 16. The spiral blade 21 is rotatably installed in the oil outlet pipe 2. The spiral blade 21 rotates in the oil outlet pipe 2, which can prevent the oil outlet pipe 2 from being blocked during oil draining and improve the oil draining efficiency. A third bevel gear 17 is fixedly installed on the rotating rod 16. Two mutually symmetrical threaded rods 18 are rotatably connected inside the oil drainer body 1.

[0020] Both threaded rods 18 have bevel gears 19 fixedly installed at one end, and both bevel gears 19 mesh with bevel gears 17. Both threaded rods 18 are threadedly connected to cleaning blocks 20, which are made of corrosion-resistant material. This corrosion-resistant material reduces the corrosion of the cleaning blocks 20 and extends their service life. An oil outlet pipe 2 is opened on the oil drainer body 1, and multiple sliding grooves 3 are opened inside the oil drainer body 1. A filter screen 4 is slidably connected to the multiple sliding grooves 3. A rotary motor 5 is fixedly installed on the oil drainer body 1. Rotary motor 5 is existing technology, which can make an object connected to its motor shaft rotate. Rotary motor 5 has a rotating rod 6 fixedly connected to its motor shaft. A bevel gear 7 is fixedly installed at one end of the rotating rod 6. A cross rod 8 is fixedly installed on the oil drainer body 1. A rotating rod 9 is rotatably connected to the cross rod 8. A bevel gear 10 is fixedly installed at the lower end of the rotating rod 9. The bevel gear 10 meshes with the bevel gear 7. Two symmetrical cleaning blocks 11 are fixedly installed at the upper end of the rotating rod 9. Vibration components are installed on both cleaning blocks 11.

[0021] With the above structure, when the rotary motor 5 rotates, it will cause the bevel gear 7 and bevel gear 10 to rotate, which in turn drives the rotating rod 6 to rotate and the cleaning block 11 to rotate, thus sweeping away solid particles from the filter screen 4. The vibration component includes a sliding opening on the cleaning block 11, and a lifting block 12 is slidably connected inside the sliding opening. Springs 13 are fixedly installed at both ends of the lifting block 12, and the other ends of the two springs 13 are fixedly connected to the cleaning block 11. Multiple protrusions and concave blocks 14 are fixedly installed on the upper surface of the cross rod 8. The upper ends of the multiple protrusions and concave blocks 14 are all round, so the protrusions and concave blocks 14 can quickly lift the lifting block 12. With the above structure, when the cleaning block 11 rotates, it will drive the lifting block 12 to rotate. Therefore, when it comes into contact with the protrusions and concave blocks 14, it will lift them up, causing the lifting block 12 to vibrate the filter screen 4 and rebound under the action of the springs 13.

[0022] All components in this utility model are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. At the same time, the standard parts used in this application can be purchased from the market. Each component in this application can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. This application will not explain the control method and circuit connection in detail, and will not be described in detail here.

[0023] In this invention, when draining oil, the operator turns on the rotary motor 15, which rotates the rotating rod 16, thereby rotating the bevel gear 17 and the bevel gear 19. This, in turn, rotates the two threaded rods 18, causing the two cleaning blocks 20 to rise and fall to clean the inside of the drainer body 1. The rotation of the rotating rod 16 also rotates the spiral blade 21, preventing blockage of the oil outlet pipe 2 during draining. After draining, the operator turns on the rotary motor 5, which rotates the bevel gear 7 and the bevel gear 10, causing the rotating rod 6 to rotate. This causes the two cleaning blocks 20 to rotate simultaneously and clean the bottom of the filter screen 4. During rotation, the lifting block 12 is continuously lifted by the bump block 14 and falls back under the rebound of the spring 13, thus causing cyclical vibration of the filter screen 4. This accelerates the falling of solid particles, preventing them from clogging the filter screen 4 and meeting the operator's needs.
