Description

Technical Field

[0001] This utility model relates to the field of rotary sprayer technology, and in particular to a five-stage variable speed rotary sprayer with a rotating nozzle. Background Technology

[0002] With the rapid development of my country's economy and automobile industry, and the increasing awareness of energy conservation and environmental protection, people have higher and higher requirements for the performance of oil products, and the classification of oil products is becoming more and more detailed. Oil products produced directly in refineries need to be blended to meet standards. In addition, oil commercial depots and oil reserve depots have storage tanks for storing various refined oil products, semi-refined oil products, crude oil, fuel oil, heavy oil and other oil products. These oil products will stratify after storage. Therefore, corresponding countermeasures for blending and dealing with the stratification of media in the tanks have been designed. Some methods use air blowing to deal with it, while others use side wall agitators.

[0003] Traditional methods of blending and stratifying oil products using aeration require a large amount of energy to maintain the operation of the aeration equipment in order to generate enough gas to agitate the oil. When the side wall agitator is working, the motor needs to run at high load for a long time to drive the agitator blades, which also consumes a lot of electrical energy. The aeration method relies on the slow diffusion of gas to drive the oil mixing, which is inefficient. The side wall agitator is limited by the mixing range and the rotation speed of the blades, making it difficult to quickly achieve uniform mixing of oil products in the tank.

[0004] Therefore, in response to the problems of high energy consumption, long processing time, poor safety, and failure to achieve the user's expected results with the above-mentioned traditional devices, a five-stage variable speed rotary nozzle can be designed. Utility Model Content

[0005] In order to overcome the problems of high energy consumption, long processing time, poor safety, and failure to achieve the user's expected results of traditional devices.

[0006] The technical solution is as follows: A five-stage variable speed rotary nozzle includes a base; the base is mounted on a pipe flange, and a reduction gearbox is mounted on the upper end of the base. An input shaft is located inside the reduction gearbox, and its upper end is connected to the upper end of a frame seal. A first output shaft is located inside the reduction gearbox, and a worm gear is connected to its outer side. A primary gear, an idler gear, and an internal gear are connected to the upper part of the reduction gearbox. The top of the reduction gearbox is fixed to a top cover by bolts. A second output shaft is mounted at the center of the lower end of the top cover, and a primary gear is connected to its outer side. An idler gear is meshed with the outer side of the primary gear, and an internal gear is meshed with the outer side of the idler gear. The lower end of the internal gear... The rotating shell is fixed with bolts, and a sealing ring is installed between the rotating shell and the gearbox. Friction rings are installed between the lower end of the rotating shell and the base, and between the upper end of the rotating shell and the top cover. Spray nozzles are evenly arranged at different angles around the rotating shell, and a power impeller is connected below the input shaft. The gearbox, as the core transmission component, integrates multi-stage transmission components to gradually transfer and convert the energy collected by the power impeller to provide power for the rotation of the rotating shell. The design of the rotating shell and spray nozzles allows the medium to be sprayed in all directions during rotation. This structural design is the key to achieving efficient blending and anti-settling functions.

[0007] Furthermore, the input shaft and the first output shaft are connected via a worm gear drive. The number of teeth on the worm gear is inversely proportional to the rotational speed of the first output shaft. By adjusting the number of teeth on the worm gear, a portion of the five-speed transmission function can be achieved. The transmission design between the worm gear and the first output shaft is based on the speed change principle in mechanical transmission. By changing the number of teeth on the worm gear, the transmission ratio can be flexibly adjusted. In practical applications, according to the characteristics, stratification, and blending requirements of the medium in the storage tank, selecting a worm gear with an appropriate number of teeth allows the first output shaft to obtain different rotational speeds. This provides diverse input conditions for the subsequent gear transmission group's speed change, ensuring that the rotary sprayer can achieve ideal working conditions under different operating conditions and realize precise five-speed regulation.

[0008] Furthermore, the primary gear, idler gear, and internal gear constitute a gear transmission assembly. The diameter of the primary gear is smaller than that of the internal gear. Through different gear ratios and transmission relationships, the remaining speed-changing functions are achieved. The gear transmission assembly adopts an asymmetrical design, with the primary gear having a smaller diameter than the internal gear. This dimensional difference, combined with different tooth configurations, constructs a precise speed-changing system. The idler gear plays a role in changing the transmission direction and optimizing the power transmission path, making power transmission smoother and more efficient. By carefully calculating and designing the gear ratios, the power transmitted from the first output shaft can be further refined and changed in speed. In conjunction with the worm gear transmission, a five-speed function is achieved. Different gear combinations correspond to different speed outputs, which can meet various working requirements from low speed and high torque to high speed and low torque, and are suitable for various complex oil blending scenarios.

[0009] Furthermore, the skeleton seal adopts a double-lip structure, forming a sealing cavity between the lips to store grease, improving the sealing effect and lubrication performance of the input shaft. The double-lip skeleton seal has a dual protection function. On the one hand, it fits tightly against the surface of the input shaft, effectively preventing the medium from leaking from the inside of the gearbox, ensuring the safety and stability of the equipment operation. On the other hand, the grease stored in the sealing cavity can continuously provide lubrication to the contact parts between the shaft and the seal during the rotation of the input shaft, reducing friction and wear, reducing equipment operating noise, and extending the service life of the input shaft and the seal. In addition, this sealing design can also prevent external impurities, dust, and other foreign objects from entering the inside of the gearbox, avoiding damage to precision components such as gear transmissions, and ensuring the normal operation of the entire transmission system.

[0010] Furthermore, the inner wall of the rotating shell is provided with a spiral guide groove, which is connected to the nozzle. After the liquid passes through the spiral guide groove, it forms a spiral jet at the nozzle. The design of the spiral guide groove is inspired by the principles of fluid mechanics. When the liquid flows in the spiral guide groove, it is constrained and guided by the groove wall, generating rotational motion and thus gaining spiral momentum. Compared with ordinary straight jet, this spiral jet has a stronger diffusion capacity and stirring effect. Inside the storage tank, the spiral jet can more effectively impact the medium stratification interface and accelerate the mixing of different components. At the same time, the spirally moving fluid forms a complex flow field inside the tank, driving more areas of the medium to participate in the flow, achieving all-round, dead-angle-free blending, and greatly improving blending efficiency and quality. In addition, the spiral jet can also reduce energy loss during the fluid jetting process and improve energy utilization efficiency.

[0011] Furthermore, the impeller blades employ a twisted design with a twist angle of 15°-30° to adapt to external dynamic fluids with varying flow velocities. This twisted design optimizes the interaction between the fluid and the blades. Under the impact of media at different flow velocities, the twisted blades allow for smoother fluid flow on the blade surface, reducing eddies and resistance, thereby improving power conversion efficiency. When the media flow velocity is low, the special shape of the twisted blades effectively captures the fluid's kinetic energy and converts it into the impeller's rotational power. Conversely, at higher media flow velocities, the twist angle prevents the concentration of impact force due to excessive flow velocity, thus preventing blade damage. By rationally setting the twist angle range of 15°-30°, the impeller can operate stably across a wide range of media flow velocities, ensuring sufficient power input for the rotary sprayer under various operating conditions and guaranteeing reliable equipment operation.

[0012] Furthermore, the base is manufactured using a casting process; the friction ring is made of copper; and the sealing ring is an O-ring. The base is suitable for standard connections with various flanges, and its outer diameter is 360mm. The casting process ensures the base has high strength and good structural stability, enabling it to withstand various forces and torques generated during the operation of the rotary nozzle, ensuring the equipment's secure installation. The 360mm outer diameter design makes it suitable for various common pipe flange standards, offering broad versatility and interchangeability, facilitating equipment installation and maintenance. The copper friction ring not only has excellent friction-reducing properties, significantly reducing frictional loss between the rotating shell and the base and reducing energy consumption, but also, due to its good conductivity, can quickly discharge static electricity generated during rotation. In flammable and explosive working environments such as petrochemical plants, timely elimination of static electricity can effectively prevent safety accidents such as fires and explosions caused by static electricity accumulation, providing reliable protection for the safe operation of the equipment. The O-ring sealing ring, with its simple structure and good sealing performance, forms a reliable sealing barrier between the rotating shell and the gearbox, preventing media leakage. The friction ring greatly reduces the coefficient of friction between the stationary base and the moving rotating shell, while also perfectly conducting static electricity between the stationary and moving parts, promptly dissipating the static electricity generated by rotation, and ensuring the safe operation of the equipment.

[0013] Furthermore, the spray nozzle adopts a conical spray nozzle or a Venturi structure spray nozzle; the gearbox is a three-stage worm gear reducer. When the flow rate and pressure of the media circulation pump can achieve the desired effect, a conical nozzle is used; when the flow rate and pressure of the media circulation pump are too low, a venturi-structured nozzle is used to increase the spraying effect. The three-stage worm gear reducer achieves a large transmission ratio and stable power output through multi-stage transmission, providing a solid foundation for the five-stage speed change of the rotary sprayer. Its compact structure and high transmission efficiency effectively reduce equipment size and energy consumption. The conical spray nozzle features a simple structure and fast spray speed. When the flow and pressure of the media circulation pump are sufficient, it can spray the media at a high speed, forming a strong jet that rapidly agitates and mixes the media in the storage tank. The Venturi structure spray nozzle cleverly utilizes the Venturi effect. When the flow and pressure of the media circulation pump are low, the special contraction-expansion structural design accelerates the fluid at the spray nozzle, increasing the spray speed and kinetic energy, enhancing the spraying effect, and ensuring that the rotary sprayer can achieve good mixing and anti-settling functions even under unfavorable operating conditions. Users can flexibly select the spray nozzle type according to actual operating conditions to achieve the best performance.

[0014] The beneficial effects are as follows: The device of this utility model is reasonably designed, using only a circulating pump as power, with a short service life and low energy consumption, achieving energy saving; the device does not use electricity in the storage tank, the rotation speed is controllable and adjustable, and it works with the optimal rotation speed and spray angle. The spray nozzles are evenly distributed circumferentially, the forces cancel each other out, and static electricity can be conducted in time, ensuring good safety; the device has a long service life, requires no maintenance, and greatly improves the blending and anti-settling effects. The primary gear, idler gear, and internal gear constitute a gear transmission group. The diameter of the primary gear is smaller than that of the internal gear. Through different gear ratios and transmission relationships, the remaining speed change functions are achieved; the gear transmission group adopts an asymmetrical design, with the diameter of the primary gear being smaller than that of the internal gear. This size difference, combined with different tooth configurations, constructs a precise speed change system; the idler gear plays a role in changing the transmission direction and optimizing the power transmission path, making the power transmission more stable and efficient; through careful calculation and design of the gear ratios, the power transmitted by the first output shaft can be further refined and speed-changed, working in conjunction with the worm gear transmission to achieve a five-level speed change function.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] Please see Figures 1-4This utility model provides an embodiment of a five-stage variable speed rotary nozzle, including a base 1; the base 1 is mounted on a pipe flange, and a reduction gearbox 15 is mounted on the upper end of the base 1. An input shaft 4 is provided inside the reduction gearbox 15, and the upper end of the input shaft 4 is connected to the upper end of a frame seal 5. A first output shaft 16 is provided inside the reduction gearbox 15, and a worm gear 6 is connected to the outside of the first output shaft 16. A primary gear 18, an idler gear 19, and an internal gear 10 are connected to the upper part of the reduction gearbox 15. The top of the reduction gearbox 15 is fixed to a top cover 11 by bolts, and a gear is installed at the center of the lower end of the top cover 11. There is a second output shaft 17, and a first-stage gear 18 is connected to the outside of the second output shaft 17. An idler gear 19 is meshed with the outside of the first-stage gear 18. An internal gear 10 is meshed with the outside of the idler gear 19. The lower end of the internal gear 10 is fixed to the rotating shell 14 by bolts. A sealing ring 12 is provided between the rotating shell 14 and the reduction gearbox 15. Friction rings 2 are provided between the lower end of the rotating shell 14 and the base 1, and between the upper end of the rotating shell 14 and the top cover 11. Spray nozzles 13 are evenly arranged at different angles around the rotating shell 14. A power impeller 3 is connected to the lower part of the input shaft 4.

[0019] The input shaft 4 and the first output shaft 16 are connected by a worm gear 6. The number of teeth of the worm gear 6 is inversely proportional to the rotational speed of the first output shaft 16. By adjusting the number of teeth of the worm gear 6, a portion of the five-speed transmission function can be achieved. The primary gear 18, idler gear 19, and internal gear 10 constitute a gear transmission group. The diameter of the primary gear 18 is smaller than the diameter of the internal gear 10. The remaining speed change functions are achieved through different gear ratios and transmission relationships between the gears. The skeleton seal 5 adopts a double-lip structure, with a sealing cavity formed between the two lips to store grease, thereby improving the sealing effect and lubrication performance of the input shaft 4. The inner wall of the rotating shell 14 is provided with a spiral guide groove, which is connected to the spray port 13. After the liquid passes through the spiral guide groove, it forms a spiral jet at the spray port 13. The blades of the power impeller 3 are designed with a twist angle of 15°-30° to adapt to external dynamic fluids with different flow rates. The base 1 is made using a casting process; the friction ring 2 is made of copper; and the sealing ring 12 is an O-ring. The nozzle 13 is a conical nozzle or a Venturi structure nozzle 13; the gearbox 15 is a three-stage worm gear reducer.

[0020] When the circulating pump is started, the medium in the storage tank flows into the rotary sprayer through the pipeline. First, the power impeller 3 begins to rotate under the impact of the flowing medium. Its blades adopt a twisted design with a twist angle of 15°-30°, which can effectively adapt to media with different flow velocities, collect the energy in the medium and convert it into its own momentum, driving the input shaft 4 connected to it to rotate. The input shaft 4 passes through the skeleton seal 5 and enters the reduction gearbox 15. The skeleton seal 5 adopts a double-lip structure, and the sealing cavity between the double lips stores grease to ensure the sealing and lubrication of the input shaft 4 when it rotates.

[0021] The rotational power of the input shaft 4 is transmitted to the worm gear 6 on the outside of the first output shaft 16. Since the worm gear 6 is connected to the first output shaft 16 and the number of teeth of the worm gear 6 is inversely proportional to the rotational speed of the first output shaft 16, the partial speed change function in the five-speed transmission can be realized by adjusting the number of teeth of the worm gear 6. The first output shaft 16 transmits power to the first-stage gear 18 on the upper part of the reduction gearbox 15. The first-stage gear 18 is installed on the outside of the second output shaft 17 at the lower center of the top cover 11.

[0022] The primary gear 18 meshes with the idler gear 19, which in turn meshes with the internal gear 10. The primary gear 18, idler gear 19, and internal gear 10 constitute a gear transmission group. By utilizing the different gear ratios and transmission relationships between the gears, the remaining speed-changing functions are achieved, thereby enabling the internal gear 10 to obtain different speeds. The lower end of the internal gear 10 is fixed to the rotating housing 14 by bolts, driving the rotating housing 14 to rotate. The sealing ring 12 between the rotating housing 14 and the reduction gearbox 15 prevents media leakage, and the friction rings 2 between the upper and lower ends of the rotating housing 14 and the base 1 and top cover 11 ensure rotational stability.

[0023] The spiral guide groove on the inner wall of the rotating shell 14 is connected to the spray nozzles 13 evenly distributed at different angles around it. After passing through the spiral guide groove, the medium forms a spiral jet flow, which is driven by the rotating shell 14 to achieve 360-degree all-round spraying. Throughout the process, the base 1 is installed on the pipe flange, and provides stable support by cooperating with the positioning boss and the positioning groove of the pipe flange. The various components in the gearbox 15 work together to complete the multi-stage speed change and transmission of power, and finally achieve the effect of rapid mixing of the medium in the storage tank and preventing sedimentation.
