Description

Technical Field

[0001] The invention relates to the technical field of oil-based mud transportation, in particular to a lifting device used in oil mining. Background Art

[0002] In the process of oil extraction and processing, it is usually necessary to cooperate with a variety of conveying equipment to proceed smoothly. In the oil field, conveying equipment is often needed to transport oil-based mud from the drilling site. At present, screw conveyors are usually used. Screw conveyors are simple in structure, stable in operation, and have a long conveying distance. They can effectively transport drill cuttings, especially mud cuttings mixed with oil, water, organic clay and chemicals in oil-based mud. The water content of oil-based mud varies according to the formula and mining conditions. When used to lift and transport oil-based mud with medium and high water content, the water tends to flow to the lower end under the action of gravity due to the inclined placement of the screw conveyor, thereby increasing the water content of the oil-based mud at the feed end of the screw conveyor. As the water content of the oil-based mud increases, it becomes thinner and difficult to enter the screw conveyor, which increases the difficulty of lifting and transportation and reduces the efficiency of lifting and transportation.

[0003] For example, a shaftless screw conveyor disclosed in a Chinese patent, with a publication number of CN105905543B, welds a spiral blade on the inner wall of a conveying cylinder. When lifting and conveying oil-based mud, especially oil-based mud with a high water content, the water in the oil-based mud is concentrated at the lower end, requiring a higher power to convey the oil-based mud, and the conveying efficiency is low. For example, a shaftless screw conveyor disclosed in a Chinese patent, with a publication number of CN108147022B, separates the oil-based mud into solid and liquid by opening a notch on the edge of the shaftless spiral blade and setting a filter in the notch. However, the separated water will still gather at the lower end of the screw conveyor, affecting the conveying of the oil-based mud later.

[0004] Therefore, a lifting device for oil mining is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a lifting device for oil mining, which solves the problem that when used to lift and transport oil-based mud with medium or high water content, water tends to flow to the lower end under the action of gravity due to the inclined placement of the screw conveyor, thereby increasing the water content of the oil-based mud at the feed end of the screw conveyor. As the water content of the oil-based mud increases, it becomes thinner and difficult to enter the screw conveyor, which increases the difficulty of lifting and transporting and reduces the lifting and transporting efficiency.

[0015] Preferably, a bottom plate is fixed to one end of the push plate, and one end of the bottom plate is pointed.

[0016] Preferably, the drainage assembly comprises a sliding rod, one end of which is fixed to one end of the shell, a sliding plate is slidably penetrated through the sliding rod, and a scraper is fixed to one end of the sliding plate.

[0017] Preferably, a through hole is opened in the shell, a filter is fixed at the through hole, and a scraper is slidably connected to the filter.

[0018] Preferably, the through hole is connected with a drain pipe, and a flow meter is fixed at one end of the drain pipe.

[0019] Preferably, a heating block is provided on the middle fixed sleeve of the shell.

[0020] Preferably, an extension rod is fixed to one end of the moving rod away from the protrusion, a magnet is fixed to one end of the extension rod, an electromagnet is magnetically matched with the magnet, a moving sleeve is fixed to one end of the electromagnet, the moving sleeve is slidably fitted with the moving rod, one end of the moving rod is slidably inserted into the moving sleeve, and one end of the moving sleeve is fixed to the support rod.

[0021] The present invention provides a lifting device for oil mining. Compared with the prior art, it has the following beneficial effects:

[0022] (1) The oil mining lifting equipment adopts a shell, a conveying motor, a rotating shaft, a fixed seat, a spiral blade, and a heating block. The feeding end of the shell is placed at the oil-based mud pile to be conveyed, and then the conveying motor is started. The conveying motor drives the rotating shaft to rotate, the rotating shaft drives the fixed seat to rotate, and the fixed seat drives the spiral blade to rotate. The oil-based mud is conveyed by the rotation of the spiral blade, thereby completing the lifting and transportation operation of the oil-based mud. It not only helps to keep the working area clean, but also plays an important role in environmental protection. The oil-based mud is conveyed by the shaftless spiral blade, which avoids the blockage of the oil-based mud during the conveying process to the greatest extent. At the same time, a heating block is coated on the outside of the middle section of the shell, and the shell and the oil-based mud inside are baked by the heating block, so that the first batch of oil-based mud attached to the inner wall of the shell will be dried under the baking of the heating block, thereby reducing the water content of the oil-based mud during the conveying process, thereby reducing the conveying difficulty and improving the conveying efficiency.

[0023] (2) The oil mining uses a lifting device, which is provided with a limit column, a protrusion, a moving rod, a support rod, a crossbar, a vertical rod, a slide seat, a slide rail, a power slider, a bottom plate, a guide rod, a wire 1, a guide plate, a positioning rod, a spring 1, a fixed rod, a lower slider, a protrusion, a wire 2, a spring 2, a U-shaped rod, an upper slider, and a push plate. The oil-based mud outside the feed end of the shell is pushed to the inside of the feed end of the shell through the push plate, so that the oil-based mud can be more easily entered into the shell for lifting and transportation, thereby avoiding the oil-based mud from being transported during transportation. As the amount of oil-based mud outside the feed end of the shell becomes less and less, the conveying efficiency gradually decreases. At the same time, it can provide a supporting force for the oil-based mud at the feed end of the shell. When conveying oil-based mud with a high water content, the water flows to a lower place due to the overall inclination of the shell, resulting in a higher water content in the oil-based mud at the feed end of the shell, making it more difficult for this part of the oil-based mud to enter the shell. The oil-based mud is pushed into the feed end through the push plate, making it easier for the oil-based mud to enter the shell, thereby reducing the difficulty of conveying and improving the conveying efficiency.

[0024] (3) The oil mining lifting equipment adopts a sliding rod, a spring, a sliding plate, a scraper, a filter, a through hole, a drain pipe, a flow meter, an extension rod, a magnet, an electromagnet, and a movable sleeve. By opening a through hole at the feed end of the shell, water in the oil-based mud inside the feed end can enter the through hole, and the oil-based mud is filtered through the filter to avoid the oil-based mud being blocked in the through hole. At the same time, the scraper can scrape the oil-based mud on the surface of the filter to avoid affecting the water filtering effect. At the same time, the opening and closing degree of the push plate can be changed according to the water content of the currently transported oil-based mud, thereby reducing the transportation difficulty and improving the transportation efficiency.

[0055] Embodiment 4: The technical solution of this embodiment is different from that of embodiment 3 in that: a drainage component for auxiliary drainage is arranged in the shell 1, and the drainage component includes a sliding rod 4, a spring 41, a sliding plate 42, a scraper 43, a filter 44, a through hole 45, and a drainage pipe 46. One end of the sliding rod 4 is fixedly installed at one end of the shell 1, and a sliding plate 42 is slidably passed through the sliding rod 4. A scraper 43 is fixedly installed at one end of the sliding plate 42. The top of the scraper 43 is pointed, and the scraper 43 is arc-shaped as a whole.

Subsequently, the power element is started to discharge the water in the through hole 45 to the outside of the shell 1 through the drain pipe 46, thereby reducing the water content of the oil-based mud during transportation.

[0057] In another embodiment, a heating block 6 is wrapped on the outside of the middle section of the shell 1, and the shell 1 and the oil-based mud inside are baked by the heating block 6, so that the first batch of oil-based mud attached to the inner wall of the shell 1 will be dried under the baking of the heating block 6, and at the same time, the entire oil-based mud will also change from hard to soft from the inner wall of the shell 1 to the axial position. During the transportation process, the subsequent oil-based mud will not directly contact the inner wall of the shell 1, but will adhere to the surface of the dried oil-based mud. As the water content of the oil-based mud continues to decrease, the oil-based mud attached to the surface of the dry oil-based mud gradually increases, making the adhesion force insufficient to support these oil-based muds to continue to adhere to the inner wall of the shell 1, and these oil-based muds will be transported to the discharge port and discharged along with the subsequent oil-based mud.

[0058] Embodiment 5: The technical solutions of this embodiment that are different from the above embodiments include:

[0059] An adjustment component is added at the moving rod 202, and the adjustment component includes: a flow meter 47, an extension rod 48, a magnet 49, an electromagnet 410, and a moving sleeve 411. In this solution, the bottom of the support rod 21 is no longer directly connected to one end of the moving rod 202;

[0060] The flow meter 47 is fixedly connected to the drain pipe 46 to measure the flow rate of the water discharged from the drain pipe 46;

[0061] One end of the extension rod 48 is fixedly mounted on the end of the moving rod 202 away from the protrusion 201, and a magnet 49 is fixedly mounted on the end of the extension rod 48 away from the moving rod 202. One end of the extension rod 48 is slidably inserted into the moving sleeve 411, and the magnet 49 is also slidably inserted into the moving sleeve 411. The sliding cooperation between the magnet 49 and the moving sleeve 411 in turn limits the moving direction of the extension rod 48. The end of the moving sleeve 411 away from the extension rod 48 is fixedly mounted on the bottom of the support rod 21, and an electromagnet 410 is fixedly mounted on the inner wall of the moving sleeve 411. After the electromagnet 410 is energized, the magnetism attracts or repels the magnet 49.

[0062] When in use, the amount of water discharged from the drainage pipe 46 is measured by the flow meter 47, and the measurement result is transmitted to the control console, which determines the current drainage amount and the water content of the current oil-based mud according to the judgment result, thereby controlling the closing and opening degree of the push plate 5 in the auxiliary component;

[0063] When the water content of the oil-based mud is high, the electromagnet 410 drives the movable sleeve 411 to move by controlling the magnetic repulsion between the electromagnet 410 and the magnet 49 after being energized, and the magnetic magnitude is adjusted according to the water content, so that the electromagnet 410 drives the movable sleeve 411 to move, and the distance between the movable sleeve 411 and the extension rod 48 increases, thereby increasing the moving distance of the support rod 21 driven by the projection 201, and increasing the range of movement of the power slider 26 driven by the support rod 21, so that the opening and closing angle of the push plate 5 is larger, and the closing is more thorough;

[0064] When the water content of the oil-based mud is low, by controlling the magnetic attraction between the electromagnet 410 and the magnet 49 after being energized, and adjusting the magnetic size according to the water content, the electromagnet 410 drives the movable sleeve 411 to move, so that the distance between the movable sleeve 411 and the extension rod 48 is reduced, thereby reducing the moving distance of the support rod 21 driven by the protrusion 201, and reducing the range of movement of the power slider 26 driven by the support rod 21, making the opening and closing angle of the push plate 5 smaller and the closure less tight. At this time, the oil-based mud is drier, avoiding the situation where the torque of the conveying motor 11 is insufficient due to excessive oil-based mud being pushed at one time.

[0065] Furthermore, a spring four may be installed between the magnet 49 and the electromagnet 410 to limit the change range between the electromagnet 410 and the magnet 49.

[0066] In another embodiment different from the aforementioned embodiment, a bottom plate 27 is fixedly installed at the bottom of the push plate 5, and one end of the bottom plate 27 is pointed. When the push plate 5 falls from top to bottom along with the slide 24, the pointed bottom plate 27 helps to separate the oil-based mud, making it easier for the push plate 5 to be inserted into the oil-based mud.

[0067] In another embodiment different from the aforementioned embodiment, a guide rod 301 is installed corresponding to the fixed rod 213 and the U-shaped rod 32, and the fixed rod 213 and the U-shaped rod 32 are guided and limited by the guide rod 301, so that the fixed rod 213 and the U-shaped rod 32 can maintain linear movement during the movement under the action of external force, and the guide rod 301 can provide support for the U-shaped rod 32.
