Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a filtration device for high-viscosity catalytic oil slurry. Background Technology

[0002] Catalytic slurry is the heavy component remaining at the bottom of the distillation column after heavy oil has been processed by a catalytic cracking unit. Catalytic slurry contains a large amount of valuable heavy aromatic components, which are raw materials for the production of carbon black, needle coke, carbon fiber and a variety of chemical products. However, catalytic slurry also contains solid catalyst particles, so it is necessary to separate the solid particles from the heavy aromatic components through a filtration device.

[0003] Existing filtration devices typically stir the catalytic oil slurry to prevent it from solidifying during filtration. The catalytic oil slurry then passes through a filter plate. Since solid particles cannot pass through the filter pores on the surface of the filter plate, the filtration effect is achieved. However, after prolonged use, some solid particles may become stuck in the filter pores of the filter plate, leading to filter clogging. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the prior art: after prolonged use, some solid particles in the catalytic slurry may clog the filter pores of the filter plate, leading to filter pore blockage. Therefore, this invention proposes a filtration device for high-viscosity catalytic slurry.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-viscosity catalytic oil slurry filtration device includes a body, in which a rotating rod is vertically rotatable, and multiple stirring rods are fixedly installed in a circumferential shape on the surface of the rotating rod. The rotating rod is controlled to rotate by a drive assembly, and a filter plate is rotatably sleeved at the bottom end of the rotating rod. The side wall of the filter plate is fixedly connected to the inner wall of the body.

[0007] A reciprocating lead screw is fixedly installed at the bottom of the rotating rod. A sliding plate is threaded onto the reciprocating lead screw. The sliding plate is restricted from rotation by a limiting component. A hole cleaning component is fixedly installed on the surface of the sliding plate by two connecting rods. The hole cleaning component is used to clean multiple filter holes on the surface of the filter plate. The hole cleaning component includes three mounting rings with progressively increasing diameters and multiple cleaning rods that are fixedly installed on the upper surface of the mounting rings in a circumferential shape. The multiple cleaning rods correspond to the positions of multiple filter holes on the surface of the filter plate. Adjacent mounting rings are fixedly connected by multiple connecting rods. The inner ring wall of the mounting ring with the smallest diameter is fixedly connected to the ends of the two connecting rods.

[0008] Preferably, the drive assembly includes a drive motor fixedly mounted on the upper surface of the machine body, the output shaft of the drive motor passing through the machine body and fixedly connected to the top of the rotating rod.

[0009] Preferably, the limiting component includes two symmetrical vertical limiting rods fixedly installed on the bottom wall of the machine body, and the slide plate is slidably sleeved on the two limiting rods.

[0010] Preferably, an annular cavity is formed between the outer surface and the inner surface of the machine body, and a heating coil is fixedly installed in the annular cavity.

[0011] Preferably, a rotating shaft is vertically rotatably mounted on the upper surface of the lower stirring rod, and multiple stirring plates are fixedly mounted on the surface of the rotating shaft in a circumferential shape. The surfaces of the upper stirring rods are vertically provided with through holes, and the top ends of the multiple rotating shafts pass through multiple through holes located in the same vertical direction. The multiple rotating shafts are controlled to rotate together by a transmission component.

[0012] Preferably, the transmission component includes a driving bevel gear and multiple driven bevel gears respectively fixedly mounted on the top of multiple rotating shafts. The multiple driven bevel gears are all meshed with the driving bevel gear, and the driving bevel gear is fixedly connected to the top wall of the machine body through two vertical rods.

[0013] Preferably, scrapers are fixedly installed at the ends of multiple stirring rods located on the same vertical horizontal line, and the surface of the scrapers slides in contact with the inner wall of the machine body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When the rotating rod is agitating the catalytic oil slurry to be filtered with multiple stirring rods, the multiple cleaning rods will move vertically back and forth. During the movement, the multiple cleaning rods will intermittently insert into multiple filter holes, thereby pushing out the solid particles accumulated in the filter holes, achieving the effect of cleaning the filter holes on the surface of the filter plate and avoiding clogging.

[0016] 2. The heating coil can be turned on during filtration. The catalytic slurry has strong fluidity at higher temperatures, which avoids solidification at low temperatures and can also reduce the viscosity of the catalytic slurry, thus reducing the adhesion between the catalytic slurry and the inner wall of the machine.

[0017] 3. Multiple agitator plates will rotate under the action of the transmission components, thereby increasing the agitation range and amplitude of the catalytic oil slurry and improving the agitation effect of the catalytic oil slurry;

[0018] 4. Multiple scrapers can scrape off the catalytic oil slurry adhering to the inner wall of the machine, so that the catalytic oil slurry in the machine can be fully agitated and filtered. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0026] Reference Figures 1-4 A high-viscosity catalytic oil slurry filtration device includes a body 1, a vertically rotating rod 2 inside the body 1, and multiple stirring rods 3 fixedly installed on the surface of the rotating rod 2 in a circumferential shape. The rotating rod 2 is controlled to rotate by a drive assembly, which includes a drive motor 10 fixedly installed on the upper surface of the body 1. The output shaft of the drive motor 10 passes through the body 1 and is fixedly connected to the top end of the rotating rod 2. A filter plate 4 is rotatably sleeved at the bottom end of the rotating rod 2, and the side wall of the filter plate 4 is fixedly connected to the inner wall of the body 1.

[0027] A reciprocating screw 5 is fixedly installed at the bottom of the rotating rod 2. A sliding plate 6 is threaded onto the reciprocating screw 5. The sliding plate 6 is restricted from rotation by a limiting component. The limiting component includes two symmetrical vertical limiting rods 11 fixedly installed on the bottom wall of the machine body 1. The sliding plate 6 is slidably sleeved on the two limiting rods 11. A cleaning component is fixedly installed on the surface of the sliding plate 6 by two connecting rods. The cleaning component is used to clean multiple filter holes on the surface of the filter plate 4. The cleaning component includes three mounting rings 7 with progressively increasing diameters and multiple cleaning rods 8 fixedly installed on the upper surface of the mounting rings 7 in a circumferential shape. The multiple cleaning rods 8 correspond to the positions of multiple filter holes on the surface of the filter plate 4. Two adjacent mounting rings 7 are fixedly connected by multiple connecting rods 9. The inner ring wall of the mounting ring 7 with the smallest diameter is fixedly connected to the ends of the two connecting rods.

[0028] First, the catalytic oil slurry to be filtered is put into the machine body 1. Then, the drive motor 10 is started to control the rotating rod 2 to rotate with multiple stirring rods 3 to stir the catalytic oil slurry in the machine body 1 to prevent it from solidifying. The catalytic oil slurry in the machine body 1 will flow down under its own gravity and pass through multiple filter holes on the surface of the filter plate 4. The solid particles in the catalytic oil slurry cannot pass through the filter holes on the surface of the filter plate 4, thereby achieving the filtration effect.

[0029] Simultaneously, when the rotating rod 2 rotates, the reciprocating screw 5 also rotates. The sliding plate 6, which is threaded onto the reciprocating screw 5, will move vertically back and forth with multiple mounting rings 7 and multiple cleaning rods 8 under the restriction of the limiting rod 11. During the movement, the multiple cleaning rods 8 will intermittently penetrate multiple filter holes on the surface of the filter plate 4, thereby pushing out the solid particles accumulated in the filter holes, achieving the effect of cleaning the filter holes on the surface of the filter plate 4 and avoiding clogging.

[0030] An annular cavity is formed between the outer and inner surfaces of the body 1, and a heating coil 12 is fixedly installed inside the annular cavity.

[0031] When the catalytic slurry is being filtered, the heating coil 12 can be turned on to heat the catalytic slurry located inside the body 1. The catalytic slurry has strong fluidity at higher temperatures, while avoiding solidification at low temperatures. This also reduces the viscosity of the catalytic slurry and decreases the adhesion between the catalytic slurry and the inner wall of the body 1.

[0032] A rotating shaft 13 is vertically mounted on the upper surface of the stirring rod 3 located below. Multiple stirring plates 14 are fixedly mounted on the surface of the rotating shaft 13 in a circumferential shape. The surfaces of the multiple stirring rods 3 located above are vertically opened with through holes. The tops of the multiple rotating shafts 13 pass through multiple through holes located in the same vertical direction. The multiple rotating shafts 13 are controlled to rotate together by a transmission component. The transmission component includes a driving bevel gear 15 and multiple driven bevel gears 16 fixedly mounted on the tops of the multiple rotating shafts 13. The multiple driven bevel gears 16 are meshed with the driving bevel gear 15. The driving bevel gear 15 is fixedly connected to the inner top wall of the machine body 1 through two vertical rods.

[0033] When the rotating rod 2 rotates with multiple stirring rods 3, the multiple driven bevel gears 16 will rotate with multiple rotating shafts 13 respectively under the cooperation of multiple driven bevel gears 16 and driving bevel gears 15, thereby causing multiple stirring plates 14 to rotate, which can increase the stirring range and stirring amplitude of the catalytic oil slurry and improve the stirring effect of the catalytic oil slurry.

[0034] Multiple stirring rods 3 located on the same vertical horizontal line have scrapers 17 fixedly installed at their ends, and the surface of the scraper 17 slides in contact with the inner wall of the machine body 1.

[0035] The scraper 17 can rotate together with the rotating rod 2 and multiple stirring rods 3, which can scrape off the catalytic oil slurry adhering to the inner wall of the machine body 1, so that the catalytic oil slurry in the machine body 1 can be fully stirred and filtered.

[0036] In this invention, the catalytic slurry to be filtered is first placed into the machine body 1. Then, the drive assembly controls the rotating rod 2 to rotate multiple stirring rods 3, which agitates the catalytic slurry in the machine body 1 to prevent it from solidifying. The catalytic slurry in the machine body 1 flows down under its own gravity and passes through multiple filter holes on the surface of the filter plate 4. Solid particles in the catalytic slurry cannot pass through the filter holes on the surface of the filter plate 4, thus achieving the filtration effect. At the same time, when the rotating rod 2 rotates, the reciprocating screw 5 also rotates. The sliding plate 6 threaded onto the reciprocating screw 5 moves vertically back and forth with multiple mounting rings 7 and multiple cleaning rods 8 under the restraint of the limiting component. During the movement, the multiple cleaning rods 8 intermittently penetrate multiple filter holes on the surface of the filter plate 4, thereby pushing out the solid particles accumulated in the filter holes, achieving the effect of cleaning the filter holes on the surface of the filter plate 4 and preventing clogging.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
