Description

Technical Field

[0001] This utility model relates to the field of turbine vacuum pump technology, and in particular to a turbine vacuum pump unit with a two-stage inlet flow rate regulation function. Background Technology

[0002] Turbine vacuum pumps are key equipment widely used in chemical, power, metallurgical, and pharmaceutical industries. They are mainly used to extract gas from sealed containers to achieve a vacuum environment or to transport and compress gas. With the continuous upgrading of industrial production processes, increasingly higher requirements are being placed on the operational stability and adaptability of turbine vacuum pump units.

[0003] Most existing turbine vacuum pumps have only one inlet, or while they may have multiple inlets, they lack an effective flow regulation mechanism, resulting in poor performance under different process conditions. Furthermore, existing flow regulation functions are generally manual, which is complex to operate, lacks precision, and inlet flow fluctuations can easily lead to operational instability, affecting equipment reliability and service life. Utility Model Content

[0004] In view of existing technologies, most existing turbine vacuum pumps have only one inlet, or although they have multiple inlets, they lack an effective flow regulation mechanism, resulting in poor performance under different process conditions. In addition, existing flow regulation functions are generally manual, which is complicated to operate, has low precision, and inlet flow fluctuations can easily cause operational instability, affecting equipment reliability and service life. This utility model provides a turbine vacuum pump unit with a two-stage inlet flow regulation function.

[0005] The technical solution adopted in this utility model is as follows: a turbine vacuum pump unit with dual-stage inlet flow regulation function, including a base, a control box fixedly installed on one side of the upper part of the base, a turbine vacuum pump body connected to one side of the control box, a connecting pipe fixedly installed on one side of the turbine vacuum pump body, two symmetrical air inlet pipes fixedly installed at the bottom of the connecting pipe, an air inlet fixedly installed at one end of each of the two air inlet pipes, and an air outlet pipe fixedly installed on the other side of the turbine vacuum pump body. A flow regulation component for easy adjustment of the intake air volume is installed inside each of the two air inlets. The flow regulation component includes a mounting plate and an adjustment ring. By setting the base, control box, turbine vacuum pump body, and other core components, the integrated layout of the unit is achieved. The symmetrical design of the dual-stage air inlet pipes and air outlets, combined with the independent flow regulation component, provides a structural basis for dual-stage inlet flow regulation, allowing flexible adjustment of the intake air volume according to different operating conditions, and improving the unit's adaptability to complex working environments.

[0006] Furthermore, there are two mounting plates, which are fixedly installed inside the air inlet. The adjusting ring is installed between the two mounting plates. Each of the two mounting plates has multiple air inlets arranged in a circumferential array on its surface. The inner surface of the adjusting ring is fixedly equipped with baffles of the same number as the air inlets, and the size of the baffles is the same as the size of the air inlets. The circumferentially arrayed air inlets on the mounting plates and the matching baffles on the adjusting ring form a precise flow regulation structure. By changing the relative position of the baffles and the air inlets, continuous and precise flow regulation can be achieved, with a wide adjustment range and high accuracy.

[0007] Furthermore, a fixing plate is fixedly installed on the top of the air inlet, a motor is fixedly installed on one side of the fixing plate, a gear is fixedly installed on the output end of the motor, several teeth are fixedly installed on the surface of the adjusting ring, a through hole is opened above the air inlet, the gear meshes with the multiple teeth through the through hole, and the motor is driven by the meshing of the gear and the teeth of the adjusting ring, thereby realizing precise rotation control of the adjusting ring.

[0008] Furthermore, each of the two mounting plates has a rotating groove on its surface near the adjusting ring. Rotating rings that fit into the rotating grooves are fixedly installed on both sides of the adjusting ring. The adjusting ring is rotatably connected between the two mounting plates through the rotating rings. The fitting design between the rotating rings and the rotating grooves makes the rotation of the adjusting ring between the two mounting plates more stable and smooth, reduces rotational friction resistance, reduces component wear, and extends the service life of the adjusting assembly.

[0009] Furthermore, the diameters of the two mounting plates and the adjusting ring are the same as the inner diameter of the air inlet. The air inlet has a toothed annular groove inside. The mounting plates and the adjusting ring have the same inner diameter as the air inlet, which reduces gas leakage during the flow process, improves air intake efficiency and the accuracy of flow regulation. The toothed annular groove provides reasonable space for the meshing of teeth and gears, avoids frictional interference between the teeth and the inner wall of the air inlet, and ensures the stable operation of the transmission structure.

[0010] Furthermore, protective frames are fixedly installed above both air inlets to prevent external dust and impurities from entering critical components such as motors and gears, reducing the risk of malfunctions caused by contaminants and extending the maintenance cycle of components. At the same time, the protective frames prevent personnel from accidentally touching transmission components during unit operation, improving the safety of unit operation.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model, through a symmetrical design of a dual-stage inlet pipe and inlet, coupled with an independent flow regulation component, provides a structural foundation for dual-stage inlet flow regulation. It allows for flexible adjustment of the intake volume according to different operating conditions, improving the unit's adaptability to complex working environments. This solves the problem that most existing turbine vacuum pumps have only one inlet, or, although they have multiple inlets, lack an effective flow regulation mechanism, resulting in poor performance under different process conditions. Furthermore, existing flow regulation functions are generally manual, which is complex to operate, lacks precision, and inlet flow fluctuations can easily lead to operational instability, affecting equipment reliability and service life.

[0013] 2. Secondly, the protective frame of this invention can prevent external dust and impurities from entering key components such as motors and gears, reducing the risk of malfunctions caused by contaminants and extending the maintenance cycle of components. At the same time, the protective frame can prevent personnel from accidentally touching transmission components during unit operation, improving the safety of unit operation.

[0020] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described below.

[0021] To address the problems existing in the background technology, this application proposes the following technical solution: a turbine vacuum pump unit with dual-stage inlet flow regulation function.

[0022] The specific technical solution includes a base 1, with a control box 2 fixedly installed on one side of the base 1. A turbine vacuum pump body 3 is connected to one side of the control box 2, and a connecting pipe 4 is fixedly installed on one side of the turbine vacuum pump body 3. Two symmetrical air inlet pipes 5 are fixedly installed at the bottom of the connecting pipe 4, and each of the two air inlet pipes 5 has an air inlet 6 fixedly installed at one end. An air outlet pipe 7 is fixedly installed on the other side of the turbine vacuum pump body 3. Flow regulating components 8 are installed inside the two air inlets 6 to facilitate the adjustment of the airflow. The flow regulating components 8 include a mounting plate 801 and an adjusting ring 802. The control box 2, as the control core of the unit, can regulate the operating status of the turbine vacuum pump body 3 and the flow regulating components 8. Gas enters the unit through the air inlets 6 at one end of the two symmetrically arranged air inlet pipes 5. After the flow rate is regulated by the flow regulating components 8, the gas enters the turbine vacuum pump body 3 through the connecting pipe 4 for processing. The processed gas is finally discharged through the air outlet pipe 7.

[0023] Reference Figures 1 to 3As shown, there are two mounting plates 801, which are fixedly installed inside the air inlet 6. An adjusting ring 802 is installed between the two mounting plates 801. Multiple air inlets 803 arranged in a circular array are opened on the surface of both mounting plates 801. The inner surface of the adjusting ring 802 is fixedly fitted with baffles 804, the same number as the air inlets 803, and the size of the baffles 804 is the same as the size of the air inlets 803. A fixing plate 805 is fixedly installed on the top of the air inlet 6. A motor 806 is fixedly installed on one side of the fixing plate 805. A gear 807 is fixedly installed on the output end of the motor 806. Several teeth 808 are fixedly installed on the surface of the adjusting ring 802. A through hole 809 is opened above the air inlet 6. 807 is engaged with multiple teeth 808 through through holes 809. Rotating grooves 810 are provided on the surface of the two mounting plates 801 near the adjusting ring 802. Rotating rings 811 that fit with the rotating grooves 810 are fixedly installed on both sides of the adjusting ring 802. The adjusting ring 802 is rotatably connected between the two mounting plates 801 through the rotating rings 811. The diameters of the two mounting plates 801 and the adjusting ring 802 are the same as the inner diameter of the air inlet 6. The air inlet 6 has a toothed annular groove 812 inside. Protective frames 813 are fixedly installed above the two air inlets 6. The motor 806 starts and drives the gear 807 to rotate. The gear 807 drives the adjusting ring 802 to rotate through meshing with the teeth 808. As the regulating ring 802 rotates, the area of ​​the baffle 804 blocking the air inlet 803 changes: when the baffle 804 is completely offset from the air inlet 803, the flow rate is at its maximum; when partially blocked, the flow rate decreases proportionally; when completely blocked, the gas flow at the air inlet 6 is blocked. Since both air inlets 6 are equipped with independent flow regulating components 8, the control box 2 can control the two motors 806 separately to achieve independent flow regulation of the two-stage inlets.

[0024] Reference Figure 1 As shown, protective frames 813 are fixedly installed above the two air inlets 6. The protective frames 813 above the air inlets 6 can protect the transmission components such as the motor 806 and gear 807, prevent dust and debris from entering or accidental contact by personnel, and ensure the stability and safety of the adjustment process.

[0025] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0026] In use, the gas to be treated enters through two symmetrically arranged air inlets 6. The control box 2 sends an adjustment command to the motor 806 on the top fixed plate 805 of the air inlet 6 according to preset operating conditions or real-time requirements. The motor 806 starts, and the gear 807 at the output end meshes with the teeth 808 on the surface of the adjusting ring 802 in the annular groove 812 through the through hole 809 above the air inlet 6. The gear 807 drives the adjusting ring 802 to rotate flexibly within the rotating groove 810 of the mounting plate 801 via rotating rings 811 on both sides, changing the relative position of the baffle 804 on the inner surface of the adjusting ring 802 and the air inlet 803 of the mounting plate 801. By changing the degree of obstruction of the air inlet 803 by the baffle 804, the gas flow area is adjusted. When the two inlets are completely separated, the flow rate is at its maximum. When partially blocked, the flow rate decreases proportionally. When completely blocked, the gas flow through the inlet 6 is blocked. The two inlets 6 can be independently adjusted to achieve dual-stage flow control. The protective frame 813 above the inlet 6 prevents dust and debris from entering during the adjustment process and prevents personnel from accidentally touching the transmission components such as the motor 806 and gear 807, ensuring stable and safe adjustment. After the flow rate is adjusted, the gas enters the connecting pipe 4 through the inlet 6. The connecting pipe 4 then transports the gas to the turbine vacuum pump body 3. The turbine vacuum pump body 3 processes the incoming gas, completing the predetermined vacuum suction or gas compression process. The processed gas is discharged from the unit through the outlet pipe 7 on the other side of the turbine vacuum pump body 3, completing the entire gas processing process.
