Description

Technical Field

[0001] The invention relates to the field of oxygen pump reducers, in particular to an oxygen pump reducer device with a novel sealing structure. Background Art

[0002] As an indispensable equipment for aquaculture, the oxygen pump has the main function of stirring the gas-liquid interface and increasing the speed of relative movement between the gas and liquid phases, thereby accelerating the diffusion and transfer of oxygen and increasing the amount of dissolved oxygen in the aquaculture water. However, during the operation of the oxygen pump, its reducer device needs to bear a large load and wear, especially in the case of long-term uninterrupted operation. Therefore, it is particularly important to effectively seal the reducer device to prevent lubricating oil leakage and impurity intrusion.

[0003] In traditional oxygen pump reducer devices, the sealing structure often adopts a simple mechanical seal or packing seal. These traditional methods have many disadvantages, which seriously affect the working performance and life of the oxygen pump. First, the sealing surface of the mechanical seal is easy to wear, resulting in a decrease in the sealing effect and frequent leakage of lubricating oil, which not only increases the maintenance cost, but also may cause pollution to the aquaculture water. Secondly, although the packing seal has a simple structure, its sealing performance is unstable and is easily affected by factors such as medium pressure and temperature, resulting in sealing failure. In addition, the sealing effect of the traditional sealing structure is greatly reduced when dealing with high-speed, high-temperature or corrosive media. These problems not only reduce the working efficiency of the oxygen pump, but also may have an adverse effect on the aquaculture environment and even cause safety accidents. Therefore, the traditional sealing structure is improved and innovated. For this reason, the present invention proposes an oxygen pump reducer device with a new sealing structure.

[0015] Compared with the prior art, the present invention provides an oxygen pump reducer device with a novel sealing structure, which has the following beneficial effects: This device increases the gear overlap by redesigning the gear parameters. This improvement significantly reduces the noise during the transmission process, making the reducer quieter during operation.

The precise lubrication system of this device greatly improves the operating efficiency and stability of the equipment.

[0018] The snap-on connection method of the connecting parts and the connecting rods adopted in this device is not only simple and easy to operate, but also has a firm, stable and reliable connection. The above design makes the connection between the reducer and the aerator faster and more reliable, greatly simplifying the installation and maintenance process. At the same time, since the snap-on connection method is detachable, it is also convenient to maintain and replace the aerator, solving the problem of complex connection methods and difficult maintenance in traditional technologies. At the same time, the quick connection design of this device greatly improves the usability and maintainability of the equipment.

[0034] Working principle: First, when the external power source is started, the rotational power it outputs is efficiently transmitted to the sun gear 7 through the precisely designed connector. In this process, the exquisite design of the planetary gear transmission system begins to show its excellent performance. The precise meshing between the sun gear 7 and the three planetary gears 4 not only ensures the accurate power transmission, but also the helical tooth design of the planetary gear 4 greatly improves the smoothness of the transmission, effectively reduces the vibration and noise during operation, and enhances the carrying capacity of the entire system, so that the reducer can operate stably under high load. As the sun gear 7 rotates, the three planetary gears 4 orbit around it. This unique movement mode makes the power evenly distributed among the planetary gears, reducing the The planetary gear 4 is subjected to stress, which prolongs its service life. The fixed connection between the planetary gear 4 and the second planetary carrier 10, and the third bearing 11 arranged on the inner side of the second planetary carrier 10, together provide stable and reliable support for the rotation of the second planetary carrier 10. This design not only improves the stability of rotation, but also greatly reduces friction and wear, and reduces maintenance costs. While the planetary gears 4 revolve, they mesh with the teeth on the inner side of the gear ring 5 to achieve further power transmission. The gear ring 5 serves as a fixed ring, and its solid structure and precise inner tooth pattern design ensure the stability and efficiency of power transmission. At the same time, the gear ring inner cavity 13 inside the gear ring 5 provides sufficient storage space for lubricating oil, ensuring that each moving part can be lubricated during operation. Sufficient lubrication reduces wear and heat generation, and improves the operating efficiency of the entire system. The device adopts sealing and lubrication measures in multiple places, such as the sealant at the joint of the first bearing 2, the uniform lubrication design of the inner extending lubricating rod 6, and the sealing effect of the first skeleton oil seal 14 and the second skeleton oil seal 17, which together construct a highly sealed and well-lubricated operating environment. This design effectively prevents the leakage of lubricating oil and avoids the invasion of external impurities and moisture, thereby greatly improving the reliability and durability of the system. When the second planetary carrier 10 rotates, the second bearing 8 on its inner side provides it with stable support and reduces friction with the inner wall of the gear ring 5. This design not only improves the flexibility of rotation, but also reduces energy consumption and heat generation, making it The whole system is more energy-efficient and efficient. At the same time, the setting of the hexagonal plug 9 facilitates the filling and discharge of the lubricating oil in the inner cavity of the gear ring 5, making maintenance more convenient. Finally, the decelerated power is efficiently transmitted to the connecting piece 18 through the output gear ring 12, and then the connecting piece 18 is connected with the connecting rod 19 by a snap connection, so as to realize a fast and reliable connection between the reducer and the aerator. This connection method is not only simple and easy, but also firmly connected, which can ensure the stable transmission of power. When the reducer is working, its decelerated power is transmitted to the aerator 20 through the connecting rod 19, driving the impeller or piston and other components inside it to move, thereby compressing the air and injecting it into the water body, so as to achieve an efficient oxygenation effect. The aeration pipe 21 on the top of the aerator 20 is reasonably designed.It can accurately deliver compressed air to the area where oxygenation is needed, thus improving the efficiency and uniformity of oxygenation.
