Abstract
Description
Technical Field
[0001] This utility model belongs to the field of crude oil impurity removal technology, and in particular relates to a crude oil impurity removal pretreatment structure. Background Technology
[0002] Crude oil impurity removal is a key process that removes impurities such as water, salt, solid particles, and sulfides from crude oil through physical, chemical, and combined processes. It directly affects the quality of crude oil and the efficiency of subsequent processing. The main components of impurities include associated water during extraction, water mixed in during transportation, as well as silt, metal particles, and asphaltene.
[0003] The crude oil processing involves multiple steps, among which impurity removal is a crucial step. For the initial dehydration of crude oil with high water content, sedimentation is often used to allow the oil and water to separate into layers by static sedimentation. However, this method has low separation efficiency and is time-consuming. Pre-treatment of crude oil to reduce its water content, followed by the use of electro-dehydration technology or coalescence separation enhancement technology, can effectively improve the processing efficiency of crude oil impurity removal. Utility Model Content

[0006] The separation shell has a sinking channel inside and an overflow groove inside, with a guide plate fixed to the inner wall of the overflow groove;
[0007] An inclined plate is rotatably connected to the inner wall of an overflow trough on one side, and rotatably connected to a connecting rod on the other side. A traction rope is fixed to the top of the connecting rod, and the other end of the traction rope is installed inside the mounting housing.
[0008] Furthermore, the mounting shell is fixed to the upper surface of the separation shell, and a rotatable rope shaft is rotatably connected inside the mounting shell, with one end of the traction rope mounted on the rope shaft.
[0009] Furthermore, a ratchet is rotatably connected to the front end of the mounting housing, a throttle is fixedly attached to the ratchet, and the rear end of the throttle passes through the ratchet and is fixedly connected to the rope shaft.
[0010] Furthermore, a locking tooth is movably inserted into the outer side of the ratchet, the locking tooth is fixed to the surface of the mounting housing, and the size of the ratchet teeth matches the locking tooth.
[0011] Furthermore, a rope shell is fixed to one side of the mounting shell, and a round hole is opened on one side of the mounting shell. The round hole of the mounting shell communicates with the rope shell. A through hole is opened on the upper surface of the separation shell. The traction rope extends into the rope shell through the round hole of the mounting shell and is connected to the connecting rod through the through hole of the separation shell.
[0012] Furthermore, the connecting rod is linearly arranged from top to bottom and rotatably connected to multiple inclined plates.
[0013] Furthermore, the upper end of one side of the guide plate is attached to the connecting rod.
[0014] Furthermore, the sinking channel inside the separation shell is connected to the overflow trough inside the separation shell.
[0015] Furthermore, a liquid inlet pipe is installed on one side of the upper end of the separation shell, and the liquid inlet pipe is connected to the sinking channel. A drain pipe is installed on one side of the separation shell, and the drain pipe is connected to the sinking channel.
[0016] Furthermore, a liquid outlet pipe is installed on the upper end of one side of the separation shell, and the liquid outlet pipe is connected to the overflow tank. A sludge removal port is installed on the lower end of one side of the separation shell, and the sludge removal port is connected to the overflow tank.
[0017] The beneficial effects of this utility model are:
[0018] This invention features a sinking channel and an overflow trough inside the separation shell, with a guide plate fixed to the inner wall of the overflow trough. One side of an inclined plate is rotatably connected to the inner wall of the overflow trough at both ends, while the other side is rotatably connected to a connecting rod. A traction rope is fixed to the top of the connecting rod and installed inside the mounting shell. When pre-treatment of crude oil is required, the crude oil is guided into the sinking channel and then, through the guide plate, climbs onto the inclined plate. Some water and sediment are then discharged through a drain pipe. When cleaning the inclined plate is needed, the rope shaft is rotated, causing the inclined plate to rotate to a near-vertical position, allowing water to be introduced into the overflow trough to wash away impurities on the inclined plate. This design facilitates crude oil pre-treatment for impurity removal and also makes cleaning the pre-treatment device easier. Attached Figure Description

[0029] Please see Figures 1 to 4 A crude oil impurity removal pretreatment structure, comprising:
[0030] Separation shell 1, with a sinking channel 2 inside separation shell 1, and an overflow groove 5 inside separation shell 1, with a guide plate 3 fixed on the inner wall of overflow groove 5;
[0031] Inclined plate 4, with its front and rear ends rotatably connected to the inner wall of overflow trough 5 on one side, and rotatably connected to connecting rod 10 on the other side, with traction rope 9 fixed at the top of connecting rod 10, and the other end of traction rope 9 installed inside mounting shell 14.
[0032] The connecting rod 10 is linearly arranged from top to bottom and rotates to connect multiple inclined plates 4;
[0033] Multiple inclined plates are arranged linearly to increase the oil-water contact area and improve sedimentation efficiency.
[0034] All inclined plates 4 are linked by the same connecting rod 10 at the hinge point between the inclined plate 4 and the connecting rod 10, ensuring consistent inclination angle.
[0035] The upper end of one side of the guide plate 3 is attached to the connecting rod 10, and the connecting rod 10 is located in the middle of the guide plate 3;
[0036] The guide plate 3 is attached to the connecting rod 10 and is centrally positioned to guide the crude oil to be evenly distributed to the inclined plate 4, avoiding local turbulence.
[0037] The sinking channel 2 inside the separation shell 1 is connected to the overflow channel 5 inside the separation shell 1.
[0038] The interface design connecting the sinking channel 2 and the overflow trough 5 between the two chambers enables seamless connection between crude oil, sedimentation, and overflow, thereby increasing the throughput.
[0039] A liquid inlet pipe 16 is installed on one side of the upper end of the separation shell 1. The liquid inlet pipe 16 is connected to the sinking channel 2. A drain pipe 15 is installed on one side of the separation shell 1. The drain pipe 15 is connected to the sinking channel 2.
[0040] The inlet pipe 16 is directly connected to the sinking channel 2, reducing the premixing process; the drain pipe 15 is located at the bottom of the sinking channel 2, prioritizing the discharge of sediment water.
[0041] In this embodiment, when crude oil needs to be pre-treated for impurity removal, in the use of this pre-treatment mechanism, after the user extracts crude oil with high water content, before removing impurities from the crude oil, the crude oil is input into the separation shell 1 through the liquid inlet pipe 16. The crude oil first flows along the sinking channel 2 to the middle of the separation shell 1, and then the crude oil spreads across the bottom of the entire distribution shell. As the crude oil level in the separation shell 1 rises, the crude oil flows along the guide plate 3 to the inclined plate 4 area, and then the crude oil climbs up along the inclined plate 4 until the crude oil flows into the overflow tank 5, and is then discharged through the liquid outlet pipe 6.
[0042] When crude oil is located in the separation shell 1, the denser water and crude oil will separate to some extent during the upward flow. When the crude oil flows to the vicinity of the inclined plate 4, it needs to pass through the inclined plate 4 to flow into the overflow tank 5. Based on the shallow pool theory, the separation efficiency can be improved by increasing the unit sedimentation area and shortening the particle settling distance. It can be seen that by using multiple inclined plates 4 to divide the crude oil flow channel into a front pool, the sedimentation and separation efficiency of crude oil can be improved, and the impurity pretreatment of crude oil can be achieved. Its surface loading rate is improved to the effect of ordinary static stratification pool. It can remove some water and other impurities such as mud, metal particles, colloids, and asphalt from crude oil with extremely high efficiency, reducing the difficulty of subsequent treatment.
[0043] A housing 14 is fixedly installed on the upper surface of the separation housing 1. A rope shaft 8 is rotatably connected inside the housing 14, and one end of the traction rope 9 is installed on the rope shaft 8.
[0044] Mounting housing 14 is fixed to the upper surface of separation housing 1 and integrates the rotating structure of rope shaft 8, which facilitates maintenance and replacement.
[0045] One end of the rope shaft 8 is supported by a bearing in the mounting housing 14 to ensure that the traction rope 9 is wound and released smoothly and to prevent jamming when the angle of the inclined plate 4 is adjusted.
[0046] The front end of the mounting housing 14 is rotatably connected to a ratchet 12, the ratchet 12 is fixedly connected to a handle 17, and the rear end of the handle 17 is fixed to the rope shaft 8.
[0047] The ratchet 12 and throttle 17 are linked, allowing the operator to gradually adjust the tilt angle of the ramp 4 and lock the angle of the ramp 4.
[0048] The ratchet 12 is inserted into the retaining tooth 7, and the size of the tooth opening of the ratchet 12 matches that of the retaining tooth 7. The retaining tooth 7 is fixed to the surface of the mounting housing 14.
[0049] The tooth 7 and ratchet 12 are matched in size to ensure that the inclined plate 4 will not be displaced due to fluid impact after the position is fixed.
[0050] The locking tooth 7 is integrally molded from a rigid material with a certain degree of elasticity, such as hard plastic or stainless steel. When the thickness of these materials is below a certain value, they have a certain degree of deformability, which makes it easy to separate the locking tooth 7 from the ratchet 12 and to quickly reset the inclined plate 4 to the initial position.
[0051] A rope shell 13 is fixed on one side of the mounting shell 14. A round hole is opened on one side of the mounting shell 14. The round hole opened in the mounting shell 14 is connected to the rope shell 13. A through hole is opened on the upper surface of the separation shell 1. The traction rope 9 extends into the rope shell 13 through the round hole opened in the mounting shell 14 and is connected to the connecting rod 10 through the through hole opened in the separation shell 1.
[0052] The design of the round hole and the through hole allows the traction rope 9 to pass through the round hole of the mounting shell 14, the rope shell 13, and the through hole of the separation shell 1 in sequence to connect with the connecting rod 10, thus preventing the traction rope 9 from being exposed.
[0053] A liquid outlet pipe 6 is installed on the upper side of one side of the separation shell 1, and the liquid outlet pipe 6 is connected to the overflow tank 5. A sludge removal port 11 is installed on the lower side of one side of the separation shell 1, and the sludge removal port 11 is connected to the overflow tank 5.
[0054] The outlet pipe 6 facilitates the discharge of crude oil after impurity removal, and at the same time facilitates the introduction of water into the overflow tank 5 to rinse the inclined plate 4. The sludge removal port 11 can discharge the impurities that have been rinsed off.
[0055] When it is necessary to clean the impurities on the inclined plate 4, the impurities in the crude oil and the crude oil itself are highly viscous, and the impurities retained on the inclined plate 4 are easy to stick to the inclined plate 4. After a period of use, the user can move the locking teeth 7, at which time the rope shaft 8 can rotate, loosen the traction rope 9, and make the connecting rod 10 slide downwards at an angle. At this time, multiple inclined plates 4 rotate to a near-vertical state. The user connects the flushing pipe to the liquid outlet pipe 6 and injects water into the separation shell 1 along the inner end of the liquid outlet pipe 6 to flush the inclined plates 4. In this state, because the inclined plates 4 rotate to a near-vertical state, the flow rate of the water is faster, which can effectively flush the impurities stuck on the inclined plates 4 and discharge the impurities from the sludge removal port 11. After the backwashing is completed, the user turns the handle 17 to drive the rope shaft 8 to rotate. At this time, the traction rope 9 pulls the connecting rod 10, which drives the connecting rod 10 back to the initial position. The locking teeth 7 and the ratchet 12 make the rope shaft 8 unable to rotate, thus fixing the connecting rod 10. This achieves the effect of making it easy to clean the inclined plate 4 and facilitating long-term use.
[0056] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
