Description

Technical Field

[0001] This utility model relates to the technical field of diesel fuel preparation equipment, specifically to an inorganic membrane purification device for refined coking diesel fuel. Background Technology

[0002] Inorganic membrane purification devices utilize the properties of inorganic ceramic membranes to separate products. Inorganic ceramic membranes are inorganic or polymeric materials with special selective separation functions. They can separate fluids into two different parts, allowing one or more substances to pass through while separating other substances. When purifying coking diesel, inorganic membrane filter elements are required to filter out the diesel.

[0003] In the prior art, CN217312773U discloses an inorganic membrane purification device for ultra-high precision purification of coking diesel. It uses an electric motor to drive a drive gear to rotate, and the drive gear drives an adjusting plate to rotate through a first rack, thereby throttling the second filter element and extending the residence time of coking diesel in the second filter element. However, when filtering out diesel, the filter element is in a fixed state, resulting in poor filtration effect. Furthermore, it cannot make the coking diesel stay in the filter element during filtration and purification. Therefore, we disclose an inorganic membrane purification device for refined coking diesel. Utility Model Content

Multiple inorganic membrane filter elements rotate during filtration, thereby improving the filtration of diesel. Simultaneously, the coking diesel will remain within each inorganic membrane filter element, enabling more precise filtration of diesel.

The multiple leakage holes correspond to the positions of multiple channels on the inorganic membrane filter element. A sealing unit is installed inside the sealing cavity.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figure 1-Figure 5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1-Figure 5 The present invention will be further described below.

[0023] This utility model discloses an inorganic membrane purification device for refined coking diesel, including a purification tank 1. Multiple purification mechanisms are rotatably installed inside the purification tank 1 and are connected sequentially from top to bottom. A driving mechanism is installed on the inner wall of the top side of the purification tank 1 and is connected to the uppermost purification mechanism. Multiple semi-annular blocks 15 are installed on the inner wall of the purification tank 1 and are staggered. Because the multiple semi-annular blocks 15 are staggered, the sealing gaskets 9 on two adjacent mounting blocks 5 are in different positions. One seals multiple leakage holes 6, while the other does not seal multiple leakage holes 6.

[0024] The purification mechanism includes a filter barrel 2. A rotating groove is provided on the outer annular part of the filter barrel 2. An annular rotating block 3 is rotatably installed in the rotating groove. The outer part of the annular rotating block 3 is fixedly connected to the inner wall of the purification tank 1 through four connecting rods. A rectangular hole is provided on the bottom inner wall of the filter barrel 2. An intermittent sealing assembly is fixedly installed in the rectangular hole. An inorganic membrane filter element 4 is installed on the top of the intermittent sealing assembly. The semi-annular block 15 corresponds to the position of the intermittent sealing assembly.

[0025] With the above structure, multiple inorganic membrane filter elements 4 can be rotated by the drive mechanism, thereby better filtering out diesel fuel. At the same time, coking diesel fuel will stay in each inorganic membrane filter element 4, thus enabling more precise filtering of diesel fuel.

[0026] Specifically, the drive mechanism includes an annular rack 18 fixedly installed on the outer side of the uppermost filter barrel 2, a motor 16 fixedly installed on the inner wall of the top side of the purification tank 1, and a gear 17 that meshes with the annular rack 18 fixedly installed at the output end of the motor 16.

[0027] In this embodiment, starting the motor 16 will drive the gear 17 to rotate. The rotation of the gear 17 will cause the ring rack 18 to rotate, thereby causing the inorganic membrane filter element 4 to rotate. With multiple inorganic membrane filter elements 4 rotating, diesel fuel can be filtered out more effectively.

[0028] Specifically, the intermittent sealing assembly includes a mounting block 5 fixedly installed on the inner wall of a rectangular hole. The top and bottom of the mounting block 5 are fixedly connected to the end of the adjacent inorganic membrane filter element 4. A sealing cavity is opened inside the mounting block 5. Multiple leakage holes 6 are opened on the inner walls of the top and bottom sides of the sealing cavity. The multiple leakage holes 6 correspond to the positions of multiple channels on the inorganic membrane filter element 4. A sealing unit is installed inside the sealing cavity.

[0029] In this embodiment, the inorganic membrane filter element 4 can be the filter element in the inorganic membrane purification device for ultra-high precision purification of coking diesel disclosed in utility model patent CN217312773U. It is an inorganic ceramic membrane filter element, which contains multiple channels inside. Multiple leakage holes 6 correspond to the positions of multiple channels on the inorganic membrane filter element 4, so that coking diesel located in multiple channels can be discharged.

[0030] Specifically, the sealing unit includes four slide rods 7, with slide plates 8 slidably sleeved on each slide rod 7. Sealing gaskets 9, corresponding to the positions of multiple leakage holes 6, are fixedly installed on the top of the slide plates 8. Circular holes 10 are formed on the top of the sealing gaskets 9 and the slide plates 8, staggered from the multiple leakage holes 6. Springs 14 are sleeved on the slide rods 7, with both ends of the springs 14 fixedly installed on the bottom of the slide plates 8 and the inner wall of the bottom side of the sealing cavity, respectively. When the slide plates 8 move, the springs 14 deform, allowing the slide plates 8 to return to their original shape after movement. The height of the inner wall of the bottom side of the sealing cavity gradually decreases from a position away from the leakage holes 6 to a position closer to the leakage holes 6, facilitating material discharge. The sealing unit also includes two sliding holes on one side of the inner wall of the sealing cavity. A U-shaped rod 12 is slidably installed in each of the two sliding holes. Both ends of the U-shaped rod 12 extend into the sealing cavity and are rotatably mounted with push rods 11. The top ends of the two push rods 11 are rotatably mounted on the bottom of the sliding plate 8. A compression wheel 13 is rotatably mounted on the bottom of the U-shaped rod 12. The compression wheel 13 corresponds to the position of the semi-annular block 15. Both ends of the semi-annular block 15 have inclined grooves. The advantage of the inclined grooves is that they facilitate contact between the compression wheel 13 and the inner wall of the semi-annular block 15. A distance is left between the bottom of the U-shaped rod 12 and the bottom inner wall of the sealing cavity, and a sealing ring is provided on the inner wall of the sliding hole. This design prevents coking diesel fuel from leaking out of the sliding hole when it falls into the sealing cavity.

[0031] In this embodiment, multiple mounting blocks 5 and multiple inorganic membrane filter elements 4 rotate together. When the mounting blocks 5 rotate, they drive the U-shaped rod 12 and the extrusion wheel 13 to rotate. When the extrusion wheel 13 contacts the semi-annular block 15, the semi-annular block 15 squeezes the extrusion wheel 13 to make it move. The movement of the extrusion wheel 13 drives the U-shaped rod 12 to move, thereby causing the two push rods 11 to rotate. The rotation of the two push rods 11 pushes the slide plate 8 and the sealing gasket 9 to move upward, thereby sealing the multiple leakage holes 6 above. When the extrusion wheel 13 separates from the semi-annular block 15, the slide plate 8 and the sealing gasket 9 move downward, thereby not sealing.

[0032] Specifically, an installation sleeve 19 is fixedly installed on the top of the inorganic membrane filter element 4 located above. The installation sleeve 19 allows the coking diesel to enter the inorganic membrane filter element 4 more effectively. A feed pipe 20 is installed on the top of the purification tank 1 for feeding materials. The feed pipe 20 corresponds to the position of the installation sleeve 19. A discharge pipe 24 is installed at the bottom of the purification tank 1 for discharging materials.

[0033] Specifically, multiple L-shaped tubes 21 are installed on the inner wall of the purification tank 1. One end of each L-shaped tube 21 extends into a multiple filter barrel 2, and the other end of each L-shaped tube 21 extends out of the purification tank 1 and is connected to a connecting pipe 23. A pump 22 is installed on the side of the purification tank 1, and the bottom end of the connecting pipe 23 is connected to the liquid inlet of the pump 22.

[0034] In this embodiment, multiple L-shaped pipes 21 can be connected by connecting pipe 23. When it is necessary to extract the filtered diesel, the diesel can be extracted by starting pump 22.

[0035] The working principle and usage process of this utility model are as follows: In use, starting the motor 16 drives the gear 17 to rotate. The rotation of the gear 17 causes the annular rack 18 to rotate. The top and bottom of the middle mounting block 5 are connected to two adjacent inorganic membrane filter elements 4. Therefore, multiple mounting blocks 5 and multiple inorganic membrane filter elements 4 rotate together. When the mounting blocks 5 rotate, they drive the U-shaped rod 12 and the extrusion wheel 13 to rotate. When the extrusion wheel 13 contacts the semi-annular block 15, the semi-annular block 15 extrudes the extrusion wheel 13, causing it to move. The movement of the extrusion wheel 13 drives the U-shaped rod 12 to move, thereby… The two push rods 11 rotate, which pushes the slide plate 8 and the sealing gasket 9 upward, thereby sealing the multiple leak holes 6 above. When the extrusion wheel 13 separates from the semi-annular block 15, the slide plate 8 and the sealing gasket 9 move downward, thus not sealing. Since the multiple semi-annular blocks 15 are staggered, the sealing gaskets 9 on the two adjacent mounting blocks 5 are in different positions. One seals the multiple leak holes 6, while the other does not seal the multiple leak holes 6. This allows the coking diesel to remain in the channels of different inorganic membrane filter elements 4 in sequence when passing through.

[0036] Then, the coking diesel is discharged through the feed pipe 20 and enters the inorganic membrane filter element 4 above. As multiple inorganic membrane filter elements 4 rotate, the diesel can be filtered out better. At the same time, the coking diesel will stay in each inorganic membrane filter element 4, so that the diesel can be filtered out more accurately. The filtered diesel is located in the space formed by the inorganic membrane filter element 4 and the filter barrel 2. The diesel can be sucked out by starting the pump 22.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
