Description

Technical Field

[0001] This utility model relates to the field of anti-settling rotary jetting technology, and in particular to an anti-settling rotary jetting device. Background Technology

[0002] The anti-settling rotary jet, also known as a rotary blender, is mainly used for anti-settling operations in crude oil and heavy oil storage tanks. It performs rotary jetting on the bottom of the tank, using a direct injection and vortex method to ensure that the heavy components deposited at the bottom of the tank can be fully mixed with the oil in the tank, reducing the amount of sediment in the tank, thereby reducing the number of tank cleaning operations and achieving energy saving and consumption reduction.

[0003] Currently, the anti-settling rotary injector mainly consists of a drive unit, a rotary injection unit, and an injector nozzle.

[0004] In existing technologies, some anti-settling injectors utilize dispersing plates to increase the diffusion range of oil or additives. However, in actual use, a significant drawback has been found: the angle adjustment of each dispersing plate must be done individually, making the process cumbersome and time-consuming. Furthermore, the manual adjustment method makes it difficult to control the displacement of each limiting column (the component used to adjust the angle of the dispersing plate), resulting in poor consistency of the dispersing plate angle and affecting the uniformity of the sprayed fluid diffusion.

[0005] Therefore, improvements are proposed. Utility Model Content

[0006] This invention is a rotary jet sprayer designed to address the shortcomings of existing technologies and prevent sedimentation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a rotary jetting device for preventing sedimentation, comprising a rotary jetting device body, wherein an installation ring is fitted on the outer surface of the top flange of the rotary jetting device body, and multiple connecting bolts are installed between the installation ring and the rotary jetting device body;

[0008] A fixed external toothed ring is fixedly connected to the inner bottom of the mounting ring. A driving internal toothed ring is engaged with the outer surface of the fixed external toothed ring. A movable external toothed ring is engaged with the top area of ​​the inner surface of the driving internal toothed ring. The movable external toothed ring is rotatably connected to the top of the fixed external toothed ring and the inner top of the mounting ring.

[0009] A synchronous transmission assembly is installed on the inner side of the movable external gear ring. A screw displacement assembly is fixedly installed on multiple output ends of the synchronous transmission assembly, and an adjustment limit post is fixedly connected to the movable ends of the multiple screw displacement assemblies.

[0010] The outer surfaces of the multiple adjusting and limiting columns are all fitted with dispersion plate assemblies.

[0011] Furthermore, the screw ends of the multiple connecting bolts are all set through the mounting ring, and the outer surface of the top flange of the rotary injector body is provided with multiple screw holes, and the screw holes are threadedly connected to the adjacent connecting bolts. The connection and installation of multiple connecting bolts can avoid single-point stress concentration and facilitate disassembly and maintenance.

[0012] Furthermore, a matching rubber pad is fixedly sleeved on the outer surface of the fixed outer gear ring, and the rubber pad abuts against the driving inner gear ring. The rubber pad can increase the moving resistance of the driving inner gear ring, making it less likely to move.

[0013] Furthermore, multiple auxiliary plates are uniformly fixedly connected to the outer surface of the driving internal gear ring, and the setting of the auxiliary plates facilitates manual driving of the driving internal gear ring to rotate.

[0014] Furthermore, the synchronous transmission assembly includes a ring bevel gear, which is fixedly mounted on the inner surface of the movable external gear ring. Multiple small bevel gears are meshed on the outer surface of the ring bevel gear, which can synchronously drive multiple screw displacement assemblies to operate. At the same time, the ring bevel gear and the small gears can cooperate to change the direction of force transmission.

[0015] Furthermore, each of the aforementioned screw displacement components includes an adjusting screw, and the adjusting screw is rotatably mounted on one side of the inner wall of the mounting ring. The outer surface of the adjusting screw is threaded with a slide block, which passes through the mounting ring and is fixedly connected to the adjusting limit post, facilitating the movement of the adjusting limit post.

[0016] Furthermore, the top of the mounting ring is provided with multiple travel grooves that extend to the bottom, and the slide block slides in contact with the inner walls on both sides of the travel grooves. The travel grooves have a limiting effect on the slide block, which can both ensure the stability of the slide block movement and prevent the slide block from overtraveling.

[0017] Furthermore, each of the plurality of dispersion plate assemblies includes a fixing rod, and the fixing rod is fixedly installed on the top of the mounting ring. Two first circular sleeves are rotatably sleeved on the outer surface of the fixing rod, and a second circular sleeve is provided between the two first circular sleeves and sleeved on the outer surface of the fixing rod. The outer surfaces of the two first circular sleeves are jointly fixedly connected to the dispersion plate body, and one side of the outer surface of the second circular sleeve is also fixedly connected to the dispersion plate body. The arrangement of the second circular sleeve and the first circular sleeve enables the rotatable connection between the dispersion plate body and the fixing rod.

[0018] The beneficial effects of this utility model are:

[0019] In use, this utility model relates to an anti-settling rotary jet injector. Simply lift the driving inner gear ring to disengage it from the fixed outer gear ring, allowing the movable outer gear ring to rotate freely. This, through a synchronous transmission assembly, drives multiple screw displacement assemblies to move synchronously, achieving synchronized adjustment of all adjusting limit posts. This design requires only a single lifting and rotation action to complete the synchronous adjustment of all dispersion plate angles, solving the problems of cumbersome and time-consuming operation that requires adjusting each adjusting limit post individually in existing technologies, thus ensuring the consistency of the dispersion plate angles. Simultaneously, after adjustment, the driving inner gear ring resets and engages with the fixed outer gear ring, forming a lock, effectively preventing positional displacement under fluid impact on the adjusting limit posts.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 5 As shown, a rotary injector for preventing sedimentation is disclosed, comprising a rotary injector body 4. A mounting ring 2 is fitted on the outer surface of the top flange of the rotary injector body 4. Multiple connecting bolts 9 are installed between the mounting ring 2 and the rotary injector body 4. The threaded ends of the multiple connecting bolts 9 all penetrate the mounting ring 2. Multiple threaded holes are opened on the outer surface of the top flange of the rotary injector body 4, and the threaded holes are threadedly connected to adjacent connecting bolts 9. The connection position between the mounting ring 2 and the top flange of the rotary injector body 4 has been shown in the prior art patent publication CN221580275U, which is an oil blending rotary injector, and therefore will not be described or shown in this application.

[0030] A fixed external toothed ring 16 is fixedly connected to the inner bottom of the mounting ring 2. A driving internal toothed ring 5 is engaged on the outer surface of the fixed external toothed ring 16. A movable external toothed ring 17 is engaged on the top area of ​​the inner surface of the driving internal toothed ring 5. The movable external toothed ring 17 is rotatably connected to the top of the fixed external toothed ring 16 and the inner top of the mounting ring 2. A matching rubber pad 18 is fixedly sleeved on the outer surface of the fixed external toothed ring 16, and the rubber pad 18 abuts against the driving internal toothed ring 5. Annular grooves are provided at the top and bottom of the movable external toothed ring 17. Matching protrusions are provided at the top of the fixed external toothed ring 16 and the inner top of the mounting ring 2, forming a limiting installation of the movable external toothed ring 17.

[0031] Multiple auxiliary plates 6 are uniformly fixedly connected to the outer surface of the drive internal gear ring 5. The auxiliary plates 6 and the drive internal gear ring 5 are designed as an integral unit, which ensures structural strength while reducing processing steps.

[0032] A synchronous transmission assembly is installed on the inner side of the movable external gear ring 17. The synchronous transmission assembly includes an annular bevel gear 15, which is fixedly installed on the inner surface of the movable external gear ring 17. Multiple small bevel gears 11 are meshed on the outer surface of the annular bevel gear 15. Screw displacement assemblies are fixedly installed on multiple output ends of the synchronous transmission assembly. Adjustment limit pins 3 are fixedly connected to the movable ends of the multiple screw displacement assemblies. Each screw displacement assembly includes an adjusting screw 14, which is limited to rotation and installed on one side of the inner wall of the mounting ring 2. A slide block 13 is threaded onto the outer surface of the adjusting screw 14, and the slide block 13 passes through the mounting ring 2 and is fixedly connected to the adjustment limit pin 3. Multiple stroke grooves 12 extending to the bottom are opened at the top of the mounting ring 2, and the slide block 13 slides against the inner walls on both sides of the stroke groove 12. When the driving internal gear ring 5 drives the movable external gear ring 17 to rotate, the annular bevel gear 15 rotates synchronously, driving each small bevel gear 11 to rotate in the opposite direction at the same speed. Each small bevel gear 11 drives the corresponding adjusting screw 14 to rotate. Since the slide 13 is constrained by the stroke groove 12 and cannot rotate, the slide 13 is forced to move along the screw axis.

[0033] The outer surfaces of multiple adjusting limit posts 3 are all fitted with dispersion plate assemblies. Each dispersion plate assembly includes a fixing rod 10, which is fixedly installed on the top of the mounting ring 2. The outer surface of the fixing rod 10 is rotatably sleeved with two first circular sleeves 7. A second circular sleeve 8 is provided between the two first circular sleeves 7 and sleeved on the outer surface of the fixing rod 10. The outer surfaces of the two first circular sleeves 7 are fixedly connected to the dispersion plate body 1. The outer surface of the second circular sleeve 8 is also fixedly connected to one side of the dispersion plate body 1. The angle between the two dispersion plate bodies 1 can be adjusted within the range of 60°-120° by adjusting the limiting posts 3.

[0034] Working principle: When adjusting the dispersion plate body 1, the operator first lifts the driving internal gear ring 5 to disengage it from the fixed external gear ring 16. Then, the driving internal gear ring 5 drives the movable external gear ring 17 to rotate synchronously through gear meshing. The movable external gear ring 17 drives the inner ring bevel gear 15 to rotate, which in turn drives multiple small bevel gears 11 to rotate synchronously. Each small bevel gear 11 drives the corresponding adjusting screw 14 to rotate, causing the threaded sliding block 13 to move axially along the stroke groove 12, pushing the adjusting limit post 3 to move radially. The radial displacement of the adjusting limit post 3 pushes the dispersion plate assembly in contact with it. The dispersion plate body 1 rotates on the fixed rod 10 through the first sleeve 7 and the second sleeve 8, thereby changing its tilt angle. The angle adjustment of all dispersion plates is achieved synchronously through this linkage mechanism. After adjustment, the driving internal gear ring 5 is manually pushed to reset and re-engage with the fixed external gear ring 16. At this time, the gear ring meshing forms a mechanical self-locking mechanism.
