Description

Technical Field

[0001] The utility model relates to the technical field of oil slurry desolidification devices, in particular to an oil slurry desolidification device combined with cross flow and full amount filtration. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, the technology related to slurry desolidification equipment is also constantly improving. At present, catalytic cracking slurry contains a large amount of solid impurities. The solid impurities are mainly composed of catalyst particles and colloids and asphaltene attached to the catalyst, which will have an adverse effect on the utilization and subsequent processing of catalytic slurry.

[0003] At present, when a large amount of solid impurities contained in catalytic cracking slurry is filtered by using a slurry desolidification device, the catalytic cracking slurry is generally transported to a stationary filter screen inside the slurry desolidification device. Only the gravity of the catalytic cracking slurry itself is used to pass through the filter screen to remove impurities. This method has a slow filtering speed for the catalytic cracking slurry and is not conducive to the treatment of the catalytic cracking slurry. Utility Model Content

[0004] The purpose of the present utility model is to solve the following shortcomings in the prior art. At present, when a large amount of solid impurities contained in catalytic cracking slurry are filtered by using a slurry desolidification device, the catalytic cracking slurry is generally transported to a stationary filter screen inside the slurry desolidification device, and only the gravity of the catalytic cracking slurry itself is used to pass through the filter screen to play a role in removing impurities. This method has a slow filtering speed for the catalytic cracking slurry and is not conducive to the treatment of the catalytic cracking slurry. Instead, a slurry desolidification device combining cross-flow and full-volume filtration is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A sealing sleeve is fixedly connected to the lower surface of the support frame, and the sealing sleeve includes an integrally formed trapezoidal sleeve and a cylindrical sleeve. A piston is slidably provided inside the sealing sleeve. Two rotating shafts are rotatably connected to the box body, and a protrusion is fixedly connected to one side of the rotating shaft located below. The protrusion is connected to a slider through a hinge rod. The slider and the piston are slidably connected. A through hole is provided in the piston, and a sealing strip with a T-shaped cross section is slidably connected in the through hole. The sealing strip passes through one end of the through hole and is fixedly connected to the slider. A plurality of rotating components are provided inside the sealing sleeve.

[0008] Preferably, each of the rotating components includes a knocking rod rotatably mounted on the inner wall of the sealing sleeve, the upper surface of the piston is set as an arc surface, and a plurality of round rods are fixedly connected to the arc surface, and the upper end of each round rod is in contact with the surface of the corresponding knocking rod.

[0012] Preferably, the box door is connected to the box body by a plurality of screws, and a transparent glass window is fixedly provided on the box door.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0022] Reference Figure 1-Figure 4 , a slurry desolidification device for combined cross-flow and full-quantity filtration, comprising a box body 1 and a box door 2. The interior of the box body 1 is fixedly connected to a support frame 7 with a circular cross-section, and a filter screen 17 is installed on the support frame 7. The box body 1 is fixedly connected to a feed pipe 4 and a discharge pipe, and a solenoid valve is provided on the discharge pipe. The lower surface of the support frame 7 is fixedly connected to a sealing sleeve 8. The sealing sleeve 8 includes an integrally formed trapezoidal sleeve and a cylindrical sleeve. The upper end of the trapezoidal sleeve is fixedly connected to the lower surface of the support frame 7. A piston 15 is slidingly provided inside the sealing sleeve 8. Two rotating shafts 5 are rotatably connected to the box body 1. A protrusion 18 is fixedly connected to one side of the rotating shaft 5 located below. The protrusion 18 is connected to a slider 14 through a hinged rod 13. The slider 14 and the piston 15 are slidably connected. A through hole 10 is opened in the piston 15, and a sealing strip 12 with a T-shaped cross-section is slidably connected in the through hole 10. The sealing strip 12 passes through one end of the through hole 10 and is fixedly connected to the slider 14. A plurality of rotating components are provided inside the sealing sleeve 8.

[0023] Each rotating assembly includes a knocking rod 9 rotatably mounted on the inner wall of the sealing sleeve 8. The upper surface of the piston 15 is set to an arc surface, and a plurality of round rods 11 are fixedly connected to the arc surface. The upper end of each round rod 11 is in contact with the surface of the corresponding knocking rod 9. When each round rod 11 moves upward against the inclined knocking rod 9, each knocking rod 9 can be deflected upward. During the deflection of the knocking rod 9, the bottom surface of the filter screen 17 can be knocked, and the filter screen 17 vibrates, which is conducive to the oil slurry quickly penetrating the filter screen 17.

[0024] A plurality of dispersion teeth 6 are fixedly connected to the upper rotating shaft 5, and the rotating shaft 5 and the feed pipe 4 are rotatably connected. The plurality of dispersion teeth 6 are all arranged inside the feed pipe 4. When the upper rotating shaft 5 rotates, the plurality of dispersion teeth 6 will be driven to rotate at the same time. During the rotation of the plurality of dispersion teeth 6, the catalytic cracking oil slurry inside the feed pipe 4 can be stirred and dispersed to prevent the oil slurry from solidifying together. The filter screen 17 is connected to the support frame 7 by two bolts 16. The upper surface of the support frame 7 is provided with two threaded grooves. One end of the two T-shaped bolts 16 is passed through the filter screen 17 and is threadedly connected to the corresponding threaded groove. The filter screen 17 and the support frame 7 can be firmly connected together.

[0025] Two transmission wheels are fixedly connected to the two rotating shafts 5, and the two transmission wheels are connected by a transmission belt 3. The cross-section of the upper rotating shaft 5 is rectangular, and the cross-section of the lower rotating shaft 5 is T-shaped. When the servo motor drives the upper rotating shaft 5 to rotate, the lower rotating shaft 5 rotates at the same time under the transmission action of the two transmission wheels and the transmission belt 3. The box door 2 is connected to the box body 1 through multiple screws. A transparent glass window is fixed on the box door 2. Each screw is passed through the box door 2 and threadedly connected to the box body 1. The box body 1 and the box door 2 can be firmly connected together. The box body 1 and the box door 2 have good sealing when connected. Through the transparent glass window, it is convenient and intuitive to see the filtration of the oil slurry.

[0026] In the present invention, when in use, a small amount of a fixed amount of oil slurry is continuously poured into the interior of the box body 1 through the feed pipe 4, and the servo motor drives the upper shaft 5 to rotate at the same time. Under the transmission action of the two transmission wheels and the transmission belt 3, the lower shaft 5 rotates at the same time. When the upper shaft 5 rotates, it will drive multiple dispersion teeth 6 to rotate at the same time. During the rotation of the multiple dispersion teeth 6, the catalytic cracking oil slurry inside the feed pipe 4 can be stirred and dispersed to prevent the oil slurry from coagulating together. The dispersed oil slurry will fall onto the filter screen 17, and all the oil slurry can cross-flow through the multiple filter holes on the filter screen 17 and be fully filtered. During the rotation of the lower shaft 5, the protrusion 18 will be driven to rotate. Since the two ends of the hinged rod 13 are respectively connected to the slider 14 and the protrusion 18 is hinged, and the inclination angle of the hinged rod 13 changes at the same time. In the process of the protrusion 18 rotating from the bottom to the top, under the transmission action of the hinged rod 13, the slider 14 slides relative to the piston 15 at the same time, and the sealing strip 12 moves up at the same time without sealing the upper diameter of the through hole 10, until the upper surface of the L-shaped slider 14 fits with the lower surface of the piston 15, and then the piston 15 will gradually move from the inside of the cylindrical sleeve to the inside of the trapezoidal sleeve. At this time, the oil slurry inside the trapezoidal sleeve can flow to the bottom of the box body 1 through the through hole 10, and when each round rod 11 moves up against the inclined knocking rod 9, each knocking rod 9 can be deflected upward. During the deflection of the knocking rod 9, the bottom surface of the filter screen 17 can be knocked, and the filter screen 17 vibrates, which is conducive to the oil slurry quickly passing through the filter screen 17.

[0027] During the process of the protrusion 18 rotating from the top to the bottom, the slider 14 will move downward, and the sealing strip 12 will move downward in the through hole 10 at the same time until the sealing strip 12 seals and blocks the upper diameter of the through hole 10 (as shown in the attached figure). Figure 4 As shown), when the piston 15 moves downward in the cylindrical sleeve, the piston 15 has good sealing performance when in contact with the inner wall of the cylindrical sleeve, and has a certain suction force on the oil slurry above the filter screen 17, which can accelerate the speed at which the oil slurry passes through the filter screen 17, and has a faster filtering speed for the catalytic cracking oil slurry, which is beneficial to the treatment of the catalytic cracking oil slurry.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
