Description

Technical Field

[0001] This utility model relates to the field of petroleum processing technology, specifically to a high-efficiency filtration device for petroleum impurities based on magnetic separation. Background Technology

[0002] Crude oil often contains impurities such as solid particles (e.g., silt, corrosion products), water, heavy metals (e.g., nickel, vanadium), and sulfur compounds during extraction, transportation, and storage. These impurities can lead to corrosion of refining equipment, catalyst deactivation, pipeline blockage, and affect the quality of the final oil product, increasing processing costs.

[0003] According to CN217368769U, a magnetic rod filter for removing iron is disclosed. This technology discloses a "magnetic rod filter for removing iron, including a base plate, three sets of support legs, an iron removal barrel, an inlet pipe, an outlet pipe, a motor, a first rotating shaft, a connecting plate, two sets of second rotating shafts, two sets of connecting frames and a deflector plate. The iron removal barrel is installed on the top of the base plate through the three sets of support legs, and the outlet end of the inlet pipe passes through the upper front end of the iron removal barrel and is connected to the iron removal barrel." It has the technical effect of "not only setting multiple sets of magnetic rods, but also ensuring that the multiple sets of magnetic rods are always in motion, thereby increasing the contact area between the multiple sets of magnetic rods and the slurry, thus fully removing iron substances in the slurry and improving its iron removal effect."

[0004] During the use of magnetic rod filters, when ferromagnetic particles such as iron, nickel, and cobalt in petroleum flow through the magnetic rod, the particles are magnetized under the action of the magnetic field, generating induced magnetic poles, and are thus adsorbed by the surface of the magnetic rod. After long-term operation, the adsorbed particles will form an "impurity layer" on the surface of the magnetic rod, weakening the effect of the magnetic field on the external fluid, making it difficult for new impurities to be captured, and the filtration efficiency will gradually decrease. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency oil impurity filtration device based on magnetic separation. A motor drives a gear set to rotate an annular brush sleeve to clean impurities on the surface of the magnetic rod. At the same time, an electric push rod drives the cleaning component to move up and down, achieving 360-degree automatic cleaning of the magnetic rod without dead angles, ensuring a highly efficient and thorough impurity removal effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency oil impurity filtration device based on magnetic separation, comprising a filtration mechanism for magnetic separation of metallic impurities in oil, the filtration mechanism comprising:

[0007] The main component includes a cylinder cover installed at the top of the cylinder body, and several magnetic rods distributed in a circle are installed at the bottom of the cylinder cover;

[0008] The cleaning assembly includes a housing that is slidably installed inside a cylinder. A cover is installed at the lower end of the housing. Several bushings distributed circumferentially are rotatably installed inside the housing. An annular brush sleeve is fixed to the inner wall of the bushing. A driven gear is fixed to the outer wall of the bushing, and adjacent driven gears mesh with each other. A motor is installed at the upper end of the cover. A drive gear is fixed to the output end of the motor, and the drive gear meshes with the driven gear.

[0009] Preferably, the cleaning component further includes several upper mounting holes circumferentially distributed inside the upper end of the housing, and several lower mounting holes circumferentially distributed inside the housing cover.

[0010] Preferably, the main body assembly further includes an electric push rod fixed to the top of the cylinder cover, and the output end of the electric push rod is fixed to the housing.

[0011] Preferably, the main component further includes a clamp installed between the outer wall of the upper end of the cylinder and the outer wall of the cylinder cover, and a sealing ring is installed between the top of the cylinder and the bottom of the cylinder cover.

[0012] Preferably, the main body component also includes handles fixed to both ends of the top of the cap.

[0013] Preferably, the main component further includes an inlet and an outlet connected and fixed at the left and right ends of the cylinder, and a drain outlet connected and fixed at the lower end of the cylinder, with a solenoid valve installed on the drain outlet.

[0014] Beneficial effects

[0015] This invention provides a high-efficiency oil impurity filtration device based on magnetic separation. Compared with the prior art, it has the following advantages:

[0016] 1. The motor drives the drive gear, which in turn drives multiple driven gears distributed around the circumference to rotate synchronously. The driven gears drive the ring brush sleeve to rotate through the bushing. This linkage cleaning mechanism operates smoothly and has high cleaning efficiency. It can ensure that impurities on the surface of each magnetic rod are thoroughly removed, avoiding the incompleteness of manual cleaning. The entire cleaning process is completed automatically, which greatly improves maintenance efficiency.

[0017] 2. The electric push rod drives the cleaning assembly to move up and down along the inner wall of the cylinder, so that the annular brush sleeve can cover the entire length of the magnetic rod; the up-and-down reciprocating motion combined with the rotation cleaning achieves 360-degree cleaning of the magnetic rod surface without dead angles. This design effectively solves the problem of cleaning blind spots in fixed cleaning devices and significantly improves the cleaning effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a high-efficiency oil impurity filtration device based on magnetic separation, including a filtration mechanism 1 for magnetic separation of metallic impurities in oil, the filtration mechanism 1 including:

[0025] The main component 11 includes a cylinder cover 112 installed at the upper end of the cylinder body 111, and a plurality of magnetic rods 114 arranged in a circular pattern installed at the bottom of the cylinder cover 112.

[0026] The cleaning assembly 12 includes a housing 121 slidably installed inside the cylinder 111. A cover 122 is installed at the lower end of the housing 121. Several bushings 123 are rotatably installed inside the housing 121. An annular brush sleeve 124 is fixed to the inner wall of the bushing 123. A driven gear 125 is fixed to the outer wall of the bushing 123, and adjacent driven gears 125 mesh with each other. A motor 126 is installed at the upper end of the cover 122. A drive gear 127 is fixed to the output end of the motor 126, and the drive gear 127 meshes with the driven gear 125.

[0027] In this embodiment, when it is necessary to clean the metal impurities adsorbed on the magnetic rod 114, the output end of the motor 126 drives the active gear 127 to drive multiple driven gears 125 to rotate. The driven gears 125 drive the annular brush sleeve 124 to rotate through the bushing 123, thereby cleaning the metal impurities adsorbed on the surface of the magnetic rod 114.

[0028] Specifically, the cleaning component 12 also includes several upper mounting holes 128 distributed circumferentially inside the upper end of the housing 121, and several lower mounting holes 129 distributed circumferentially inside the cover 122.

[0029] In this embodiment, the housing 121 and the cover 122 are fixed together by bolts through the upper mounting hole 128 and the lower mounting hole 129, which facilitates the maintenance and replacement of the cleaning component 12.

[0030] Specifically, the main component 11 also includes an electric push rod 113 fixed to the top of the cylinder cover 112, and the output end of the electric push rod 113 is fixed to the housing 121.

[0031] In this embodiment, the cleaning assembly 12 is driven to move up and down along the inside of the cylinder 111 by the output end of the electric push rod 113, ensuring that the annular brush sleeve 124 and the magnetic rod 114 are in full contact and there are no dead corners in the cleaning process.

[0032] Specifically, the main component 11 also includes a clamp 115 installed between the upper outer wall of the cylinder 111 and the outer wall of the cylinder cover 112, and a sealing ring 116 installed between the top of the cylinder 111 and the bottom of the cylinder cover 112.

[0033] In this embodiment, the cap 112 and the cylinder body 111 can be fixed by the clamp 115, and the sealing performance can be improved by the sealing ring 116.

[0034] Specifically, the main component 11 also includes handles 117 fixed to both ends of the top of the cap 112.

[0035] In this embodiment, after the clamp 115 is released, the cylinder cover 112 can be easily removed from the cylinder body 111 by means of the handle 117.

[0036] Specifically, the main component 11 also includes an inlet 118 and an outlet 119 that are connected and fixed at the left and right ends of the cylinder 111. A drain outlet 1110 is connected and fixed at the lower end of the cylinder 111, and a solenoid valve 1111 is installed on the drain outlet 1110.

[0037] In this embodiment, when it is necessary to clean the metal impurities adsorbed on the magnetic rod 114, the liquid inlet 118 stops injecting, the liquid outlet 119 empties the inside of the cylinder 111, and the drain outlet 1110 opens in conjunction with the solenoid valve 1111, so that the metal impurities cleaned off the magnetic rod 114 are discharged through the drain outlet 1110.

[0038] The working principle and usage process of this utility model are as follows: First, when it is necessary to clean the metal impurities adsorbed on the magnetic rod 114, the liquid inlet 118 stops injecting, the liquid outlet 119 empties the inside of the cylinder 111, and the drain outlet 1110 opens in conjunction with the solenoid valve 1111.

[0039] Then, the output end of the motor 126 drives the drive gear 127 to drive multiple driven gears 125 to rotate. The driven gears 125 drive the annular brush sleeve 124 to rotate through the bushing 123, thereby cleaning the metal impurities adsorbed on the surface of the magnetic rod 114.

[0040] Meanwhile, the cleaning assembly 12 is driven to move up and down along the inside of the cylinder 111 by the output end of the electric push rod 113, ensuring that the annular brush sleeve 124 and the magnetic rod 114 are in full contact without any cleaning dead corners; finally, the metal impurities cleaned off the magnetic rod 114 are discharged through the drain port 1110.
