Description

Technical Field

[0001] This utility model belongs to the field of rotary jet mixer technology, specifically relating to a rotary jet mixer for modifying storage tanks. Background Technology

[0002] During the operation of oil storage tanks, stirring equipment is often used to ensure uniform mixing of oil products in order to prevent stratification and sedimentation and to improve blending efficiency. Traditional stirrers include mechanical stirrers and electrostatic stirrers, but these devices often suffer from high energy consumption, complex maintenance, and poor stirring effect. To solve these problems, rotary jet stirrers have emerged, which generate rotational flow by jetting fluid to achieve uniform mixing of oil products.

[0003] In traditional technologies, the impeller is positioned perpendicular to the inlet pipeline (i.e., the impeller's axis is perpendicular to the inlet pipeline's axis), while the inlet pipeline is horizontal. This means the agitator may not be able to fully utilize the kinetic energy of the inlet pipeline. Because the impeller design is not aligned with the inlet pipeline, it cannot maximize the conversion of fluid kinetic energy, resulting in energy waste. Furthermore, the spray direction and angle of existing agitators are typically fixed, making them unadjustable for different blending requirements, thus limiting operational flexibility and system adaptability.

[0004] In view of this, we propose a method to modify storage tanks using a rotary jet agitator to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problems of the existing rotary jet mixer in terms of energy utilization, mixing effect and flow characteristics.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotary jet agitator for modifying storage tanks, comprising:

[0008] The drive impeller is horizontally positioned and designed to face the oil inlet pipeline; the shaft connected to the drive impeller is horizontally rotatable within the oil inlet housing;

[0009] The nozzle is used to spray oil in all directions to blend the oil in the oil storage tank and prevent sedimentation. The nozzle is provided in a ring and is arranged at equal intervals on the spray housing above the oil inlet housing. The nozzle includes a bent pipe connected to the flange interface on the spray housing through flange A and a nozzle threaded onto the bent pipe.

[0010] The spray direction and angle of the nozzle can be adjusted by disassembling and replacing the bend and nozzle to meet different blending needs.

[0011] Preferably, the injection housing is rotatably positioned above the oil inlet housing via a sealed bearing.

[0012] Preferably, a gear ring is fixedly provided on the spray housing, and the gear ring meshes with the pinion at the output end of the reduction gearbox, and the output end of the drive impeller is connected to the input end of the reduction gearbox.

[0013] The rotation of the drive impeller drives the gear set in the reduction gearbox to rotate, which in turn drives the pinion to rotate. The pinion meshes with the gear ring, causing the injection housing to rotate relative to the oil inlet housing, so that the injection nozzle rotates to spray in all directions.

[0014] Preferably, the reduction gearbox is fixed at the rear end of the oil inlet housing.

[0015] Preferably, the oil inlet housing is provided with mounting seats with mounting holes on both sides.

[0016] Preferably, a horizontal pipe is connected to the oil inlet housing at the end opposite to the reduction gearbox, and a flange B for connecting the oil inlet pipeline is provided on the horizontal pipe.

[0017] Preferably, an isolation shell is fixedly provided on the outer side of the oil inlet housing, which is fitted onto the outer side of the gear ring and the pinion. The isolation shell is rotatably connected to the oil inlet housing through a sealing bearing ring.

[0018] Compared with the prior art, the technical effects and advantages of this utility model are:

[0019] This tank modification utilizes a rotary jet agitator based on the synergistic action of a drive impeller and a nozzle. The drive impeller is horizontally positioned within the inlet housing. Utilizing the kinetic energy of the oil flow in the inlet pipeline, the impeller's design, aligned with the inlet pipeline, converts the fluid's kinetic energy into the impeller's mechanical energy, thus driving its rotation. The impeller's rotation is transmitted to a pinion gear within a reduction gearbox. This pinion gear meshes with a gear ring fixed to the jet housing, causing the jet housing to rotate. Consequently, the nozzle rotates and sprays oil, achieving omnidirectional agitation.

[0020] The retrofit of the storage tank with a rotary jet agitator resulted in a significant improvement in mixing performance. The impeller's design, facing the oil inlet line, enhanced the radial flow of the fluid, creating stronger turbulence, promoting uniform mixing of the oil, and improving blending efficiency and quality. This design aligns with the fluid flow direction, effectively utilizing energy and reducing energy loss during the mixing process, thereby improving overall energy efficiency.

[0021] The retrofit of the storage tank with a rotary jet agitator also improves the tank's operational safety and maintenance efficiency. The enhanced agitation improves the fluid flow within the tank, effectively preventing bottom sediment formation and reducing the frequency of tank cleaning and maintenance costs. Simultaneously, the nozzle design allows for adjustments to the spray direction and angle by replacing bends and nozzles, increasing operational flexibility and system adaptability to meet diverse blending needs.

[0022] The modification of the storage tank with a rotary jet agitator significantly enhances the tank's safety and reliability. The insulating outer shell on the jet housing protects the gear ring and pinion from external environmental influences, reducing wear and extending the equipment's service life. The sealed bearing ring design reduces friction and wear while helping to prevent oil and lubricant leakage, maintaining a clean working environment and ensuring the safe and stable operation of the equipment.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The following combination Figures 1 to 4 This application will be described in further detail.

[0030] This application discloses a rotary jet agitator for tank modification, including a drive impeller 1 and a nozzle 4. The shaft 2 connected to the drive impeller 1 is horizontally rotatably disposed in the oil inlet housing 3. The nozzle 4 is used to spray oil in all directions to mix the oil in the oil storage tank and prevent sedimentation. The nozzle 4 is provided with several nozzles arranged in a ring at equal intervals on the spray housing 5 above the oil inlet housing 3.

[0031] The injection housing 5 is rotatably mounted above the oil inlet housing 3 via a sealed bearing. A gear ring 7 is fixedly mounted on the injection housing 5, and the gear ring 7 meshes with the pinion 8 at the output end of the reduction gearbox 9. The output end of the drive impeller 1 is connected to the input end of the reduction gearbox 9. The reduction gearbox 9 is fixed at the rear end of the oil inlet housing 3.

[0032] The rotation of the drive impeller 1 drives the gear set in the reduction gearbox 9 to rotate, which in turn drives the pinion 8 to rotate. The pinion 8 meshes with the gear ring 7, causing the injection housing 5 to rotate relative to the oil inlet housing 3, so that the injection nozzle 4 rotates to spray in all directions.

[0033] Oil in the inlet pipeline flows towards the storage tank at a certain speed. When the oil flow impacts the drive impeller 1, which is designed to face the pipeline, it applies a force to the impeller, causing it to start rotating. Part of the oil's kinetic energy is converted into the impeller's mechanical energy, causing it to rotate.

[0034] The drive impeller 1 is horizontally positioned and facing the oil inlet pipeline; a horizontal port 12 is connected to the oil inlet housing 3 at the end opposite to the reduction gearbox 9, and a flange B13 for connecting to the oil inlet pipeline is provided on the horizontal port 12.

[0035] The impeller's design, facing the oil inlet line, better utilizes the inlet dynamic pressure, enhances the radial flow of the fluid, and creates stronger turbulence, thereby improving the mixing effect and resulting in more uniform oil mixing. The impeller design aligns with the fluid flow direction, enabling more efficient energy utilization and reducing energy loss during mixing. Due to the improved mixing effect, the fluid flow within the storage tank is enhanced, effectively preventing the formation of bottom sediments and reducing the frequency of tank cleaning and maintenance costs. More efficient mixing helps prevent stratification and the formation of explosive mixtures, thus improving storage safety.

[0036] The impeller's design, facing the oil inlet line, effectively utilizes the fluid's kinetic energy, converting it into mechanical energy to achieve impeller rotation. Enhanced radial flow and turbulence promote more uniform oil mixing, improving blending efficiency and quality. The design aligning with the fluid flow direction reduces energy loss during agitation. Enhanced fluidity reduces sediment formation at the bottom of the tank, decreasing the frequency and cost of cleaning and maintenance. Effective agitation prevents oil stratification and the formation of explosive mixtures, enhancing storage safety.

[0037] The nozzle 4 includes a bend 42 that is connected to the flange interface 6 on the injection housing 5 via a flange A41, and a nozzle 43 that is threaded onto the bend 42.

[0038] The spray direction and angle of the spray nozzle 4 can be adjusted by disassembling and replacing the bend 42 and the nozzle 43 to meet different blending requirements. By replacing the bend 42 and the nozzle 43, the spray parameters can be adjusted according to different blending requirements, increasing operational flexibility and system adaptability.

[0039] The oil inlet housing 3 has mounting seats 11 with mounting holes 10 on both sides. The mounting seats 11 with mounting holes 10 facilitate the installation and future maintenance of the agitator, simplifying the installation process.

[0040] An isolation housing 14 is fixedly mounted on the outer side of the oil inlet housing 3, fitting around the outer sides of the gear ring 7 and pinion 8. The isolation housing 14 is rotatably connected to the oil inlet housing 3 via a sealing bearing ring. The isolation housing 14 protects the gear ring 7 and pinion 8 from external environmental influences such as dust and oil. The rotatable connection between the sealing bearing ring and the oil inlet housing 3 reduces friction and wear, improving the equipment's service life and reliability. The sealed design facilitates the prevention of oil and lubricant leakage, maintaining a clean working environment and ensuring equipment safety.

[0041] The modified storage tank uses a rotary jet agitator to achieve mixing by driving the impeller 1 to rotate. The impeller is horizontally positioned inside the oil inlet housing 3 and is driven to rotate by the kinetic energy of the oil inlet pipeline. The rotational force is transmitted to the jet housing 5 through the reduction gearbox 9, causing the jet nozzle 4 to perform omnidirectional rotational jetting, thereby achieving the purpose of blending the oil and preventing sedimentation.

[0042] The impeller's design, facing the oil inlet line, enhances radial flow and turbulence of the fluid, improves mixing, and results in more uniform oil mixing while reducing energy consumption. This design also helps prevent bottom sediment formation, reducing tank cleaning frequency and maintenance costs, while improving storage safety.

[0043] The adjustable design of the nozzle 4 increases operational flexibility and system adaptability. By replacing the bend 42 and the nozzle 43, different blending requirements can be met. This design allows the mixer to better adapt to various working conditions, improving blending efficiency and mixing quality.

[0044] The design of the isolation housing 14 and the sealed bearing ring on the spray housing 5 protects the gear ring 7 and pinion 8, reduces the impact of the external environment and equipment wear, extends the service life of the equipment, and prevents oil and lubricant leakage, keeping the working environment clean and the equipment safe.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
