Description

Technical Field

[0001] This invention relates to the field of vacuum pump technology, specifically to an energy-saving device for vacuum pumps. Background Technology

[0002] Vacuum environments play a crucial role in modern industrial production and numerous technological applications. From high-precision vacuum coating in electronic chip manufacturing to vacuum packaging technology used in the food packaging industry to extend shelf life, and the control of vacuum conditions required for specific chemical reactions in the chemical industry, vacuum pumps, as core equipment for creating and maintaining vacuum environments, directly affect production quality, costs, and energy consumption. With the global emphasis on energy conservation and emission reduction and the continuous rise in energy costs, improving the energy efficiency of vacuum pumps has become a key direction for industry development.

[0003] Existing vacuum pump technology has several drawbacks. In practical applications, leaks in the storage tank occur frequently due to various reasons. Current technology lacks an effective buffering mechanism to effectively and precisely control internal pressure changes. When a leak occurs, the internal pressure changes rapidly, disrupting the previously stable vacuum environment. Without a buffering mechanism to balance the pressure, the vacuum pump must frequently start and stop to maintain the set vacuum level. Each start requires significant electrical energy to overcome initial resistance and reach normal operating conditions. Furthermore, frequent stopping and restarting subject critical components such as the motor to substantial current surges and mechanical stresses. Mechanical stress, this frequent start-stop not only greatly increases energy consumption, leading to a significant increase in operating costs, but also accelerates the wear and tear of internal components of the vacuum pump. In addition, during the operation of the vacuum pump, the flow of gas from the storage tank to the pump body mainly relies on the suction force of the vacuum pump itself. This single pumping method results in a slow gas flow rate, especially during the initial vacuuming, which requires a long time to extract the air from the storage tank and form the required vacuum environment. In industrial production, wasted time means reduced production efficiency, which may affect the progress of the entire production process. Moreover, the long pumping time also causes the vacuum pump to operate under high load for a long time, further increasing energy consumption and equipment wear. Summary of the Invention

[0014] Furthermore, sealing auxiliary plates are provided on both sides of the sealed side box, and a sliding limiting strip is provided on one side of the sealing auxiliary plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this solution, an air box assembly is installed to connect the main box and the auxiliary box through internal partitions, sealing diaphragms, and movable seals. During the initial vacuuming, the cooperation between the top protrusion of the main electric sealing plate and the force-bearing protrusion of the movable seal connects the interior of the main box and the auxiliary box, evacuating them to a vacuum in one go, avoiding the tedious operation of secondary vacuuming. When the storage box leaks, the sealing diaphragm deforms towards the auxiliary box under the pressure difference, allowing the vacuum in the auxiliary box to diffuse towards the main box to offset the leakage, effectively reducing the start-up frequency of the vacuum pump. Compared with the traditional single box structure, this solution has significant innovations in reducing energy consumption and maintaining the stability of the vacuum environment, improving the overall performance and service life of the vacuum pump energy-saving device.

[0017] 2. In this solution, by setting up an air duct assembly and driving an internal screw with a small motor to move the sliding block, flexible switching control of the main air supply pipe and the auxiliary air supply pipe is realized. During the initial vacuuming, the main air supply pipe can be quickly connected for efficient evacuation. When the storage box leaks and needs to be evacuated again, it can be quickly switched to the auxiliary air supply pipe to extract residual gas from the auxiliary box. This switchable evacuation path design breaks through the limitations of the traditional fixed evacuation method. It can accurately adjust the evacuation path according to different working conditions, which not only ensures the efficiency of the initial vacuuming, but also effectively maintains the system vacuum in the event of leakage, thus improving the adaptability and practicality of the vacuum pump energy-saving device.

[0018] 3. In this solution, a transmission assembly is installed, which drives the meshing frame via a drive motor, allowing the entire transmission assembly to move flexibly. This precisely positions the fan blades on the air outlet path of the air outlet duct, while simultaneously moving the central fan blade directly above the opening of the main housing. During the evacuation process, the air discharged from the air outlet duct drives the fan blades to rotate. Through the meshing transmission of the transmission belt, vertical and horizontal conical teeth, the central fan blades convert the linear airflow into a rotating vortex. This airflow conversion method forms a stable airflow boundary layer, reducing frictional losses on the inner wall of the transfer box and accelerating the flow of gas from the housing to the transfer box, significantly improving the speed and efficiency of the initial vacuum extraction.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1 to 8 A vacuum pump energy-saving device, comprising:

[0030] The base 1, serving as the stable support foundation for the entire equipment, is cast from high-strength, wear-resistant alloy material. Its surface undergoes meticulous rust-proofing and polishing processes, providing excellent corrosion resistance and ensuring flatness and stability during long-term use. A column 11, made of high-quality steel, is mounted on the upper surface of the base 1, possessing sufficient strength and rigidity to withstand the weight of the vacuum pump body 2 and related components, as well as various forces generated during operation. The vacuum pump body 2, the core power component of the entire system, is mounted on one side of the column 11. An air outlet duct 3 is located on the bottom surface of the vacuum pump body 2, while an air inlet duct 4 is located on its upper surface, serving as the channel for air to enter the vacuum pump body 2. An auxiliary mechanism is also located on the upper surface of the vacuum pump body 2, designed to further optimize the vacuum pump's performance. This auxiliary mechanism includes an air box assembly and an air duct assembly. The air duct assembly includes a transfer box 5, which plays a crucial role in air distribution and regulation. The bottom surface of the transfer box 5 is connected to the upper surface of the air inlet duct 4. The connection uses a rubber gasket and bolts with good sealing performance to ensure that there is no air leakage at the connection. Side attachment blocks 40 and side attachment boxes 24 are respectively provided on the two sides of the transfer box 5. The upper surface of the side attachment block 40 is provided with a limiting slide 41. The side attachment box 24 is equipped with a small motor 25. The output end of the small motor 25 is provided with an internal screw 39. The internal screw 39 is located inside the transfer box 5. The inner bottom surface of the body 5 is provided with an internal sliding groove 36, and the surface of the internal screw 39 is engaged with a sliding block 37. The size and shape of the internal sliding groove 36 match the sliding side plates 38 on both sides of the sliding block 37. Both sides of the sliding block 37 are provided with sliding side plates 38 that cooperate with the internal sliding groove 36. The upper surface of the transfer box 5 is provided with a main air supply pipe 33 and a secondary air supply pipe 34. The inner upper surface of the transfer box 5 is provided with two limiting arc plates 35 that correspond to the main air supply pipe 33 and the secondary air supply pipe 34 respectively.

[0031] In use, the operator connects the top air inlet 8 to the storage box that needs to be evacuated. The air duct assembly connects the vacuum pump body 2 to the air box assembly, and adjusts the evacuation path of the vacuum pump body 2 according to specific needs to meet different usage requirements. During use, the air duct assembly facilitates gas flow through the bottom air inlet pipe 4 and the top main air supply pipe 33 and auxiliary air supply pipe 34. During the initial evacuation, to ensure evacuation efficiency, the small motor 25 is started by a signal from the operator. The internal screw 39 engages with the sliding block 37, causing the sliding block 37 to move and block the bottom of the auxiliary air supply pipe 34. At this time, the vacuum pump body 2 evacuates air from inside the main box 7 through the transfer box 5. The air inside the storage box that needs to be evacuated is extracted through the top air inlet 8 to quickly create a vacuum environment. When the detector inside the storage box detects a leak after a period of use and air needs to be extracted again, the sliding block 37 is moved below the main air supply pipe 33 to block it. When extracting air again, the vacuum pump 2 extracts air from the inside of the auxiliary box 6 through the auxiliary air supply pipe 34. This ensures that the residual gas that flowed into the auxiliary box 6 due to the leak in the storage box is also extracted while maintaining a vacuum inside the storage box. This ensures that the inside of the auxiliary box 6 remains in a vacuum state so that the air box assembly can work normally.

[0032] The air box assembly includes: a connecting main box body 7, which is the core component of the air box assembly and is made of high-strength, lightweight alloy material. The upper surface of the connecting main box body 7 has a top air inlet 8. The bottom surface of the connecting main box body 7 connects to the upper surface of the main air supply pipe 33. An auxiliary box body 6 is located on one side surface of the connecting main box body 7, and the bottom surface of the auxiliary box body 6 connects to the upper surface of the auxiliary air supply pipe 34. Side openings 42 are provided on both sides of the connecting main box body 7 to increase the range of motion of the transmission assembly. The inner bottom surface of the connecting main box body 7 has an opening connecting to the main air supply pipe 33. The opening connects to the main box 7, and the inner bottom surface is also provided with a secondary electric sealing plate 43 and a main electric sealing plate 44. An electric shaft is provided at the connection between the secondary electric sealing plate 43, the main electric sealing plate 44 and the main box 7. Multiple top protrusions 45 are provided on the upper surface of the main electric sealing plate 44. An internal partition 46 is provided between the main box 7 and the auxiliary box 6, dividing the main box 7 and the auxiliary box 6 into two relatively independent spaces, but achieving limited airflow through a specific structure. A sealing diaphragm 47 is provided at the center of the internal partition 46, and the sealing diaphragm 47 uses highly elastic... Made of wear-resistant rubber material, it has good sealing performance and flexibility. During normal operation, it prevents direct mixing of airflow between the main housing 7 and the auxiliary housing 6. Only under specific conditions, such as when the movable seal 49 is activated, will the sealing diaphragm 47 deform, allowing a small amount of airflow to pass through. The surface of the internal partition 46 is also provided with multiple fixing blocks 48 for securing the sealing diaphragm 47. The fixing blocks 48 are firmly fixed to the internal partition 46 by bolts or welding, ensuring that the sealing diaphragm 47 will not loosen or shift during operation. The center of the internal partition 46... Two movable seals 49 are also provided. The movable seals 49 are key components for controlling the deformation of the sealing diaphragm 47 and the passage of airflow. The surface of the fixed connecting block 48 is provided with multiple ventilation grooves 51. The function of the ventilation grooves 51 is to provide a passage for airflow when the sealing diaphragm 47 is deformed. The side surface of the movable seal 49 opposite to the ventilation grooves 51 is also provided with a connecting auxiliary block 52. The side surface of the connecting auxiliary block 52 is provided with a connecting spring 53. The connecting spring 53 is connected to one side surface of the internal partition 46. The side surface of the movable seal 49 is also provided with a force-bearing protrusion 50 that cooperates with the top protrusion 45.

[0033] The gas box assembly is used to reduce the leakage effect of the storage box body when leakage occurs, thereby reducing the start frequency of the vacuum pump body 2 and reducing energy consumption. During the initial evacuation, the vacuum pump body 2 evacuates the storage box body through the main box body 7. During this process, the auxiliary electric sealing plate 43 and the main electric sealing plate 44 rotate and flip up under the action of the electric shaft, exposing the opening on the bottom surface of the main box body 7 that connects to the main air supply pipe 33. At this time, the main electric sealing plate 44 is in the vertical position, and the four top protrusions 45 contact the force-bearing protrusions 50 on the two movable seals 49, pushing the entire movable seal 49 to one side and stretching the connecting spring 53. At this time, the interior of the main box body 7 and the auxiliary box body 6 can be connected through the vent groove 51. At this time, during the vacuuming, the interior of the auxiliary box body 6 can also be vented. The part is also evacuated to a vacuum state. After the vacuuming is completed, the auxiliary electric sealing plate 43 and the main electric sealing plate 44 are reset under the action of the electric shaft. The movable seal 49 loses the contact effect of the top protrusion 45 and is reset under the action of the connecting spring 53. The two movable seals 49 close the opening on the surface of the internal partition 46. At this time, when leakage occurs inside the storage box, the internal pressure increases. The sealing diaphragm 47 will deform to one side of the auxiliary box 6 under the action of the pressure difference on both sides. The fixed connecting block 48 can prevent it from separating from the internal partition 46. When the sealing diaphragm 47 is deformed to a certain extent, the unconnected part of its edge will separate from the surface of the internal partition 46, exposing the gap. At this time, the vacuum inside the auxiliary box 6 will diffuse to the main box, offsetting part of the leakage, thereby reducing the starting frequency of the vacuum pump 2 and achieving the effect of reducing energy consumption.

[0034] The auxiliary mechanism also includes a transmission assembly, which comprises two sliding plates 18. Two sliding grooves 17 are formed on the upper surface of the base 1 to mate with the sliding plates 18. The dimensions and shape of the sliding grooves 17 are precisely designed; their depth and width ensure smooth sliding of the sliding plates 18 without excessive gaps, preventing wobbling or displacement during sliding. Each sliding plate 18 has a fan blade 19 on its upper surface, located on the air outlet path of the air outlet duct 3. When airflow passes through the air outlet duct 3, the airflow directly impacts the fan blade 19, causing it to rotate. The upper surface of the sliding plates 18 also has… A transmission wheel 21 is provided, and a transmission belt 20 is provided between the transmission wheel 21 and the fan blade 19. The transmission belt 20 is made of high-performance rubber material, which has good elasticity and wear resistance. It can fit tightly against the grooves of the transmission wheel 21 and the fan blade 19 to ensure that slippage does not occur during transmission. A rotating rod 22 is provided on the upper surface of the transmission wheel 21, and a connecting frame rod 16 is provided on the upper surface of the sliding plate 18. A limiting sliding plate 27 that cooperates with the limiting slide 41 is provided between the two connecting frame rods 16. The limiting sliding plate 27 can slide within a limited range on the limiting slide 41. A sealing side box 9 is provided on one side surface of the connecting frame rod 16. The rotating rod 22 penetrates the bottom surface of the sealed side box 9. A vertical conical tooth 28 is provided at the end of the rotating rod 22. A connecting support rod 32 is also provided on the inner bottom surface of the sealed side box 9. A connecting rotating rod 30 is provided between the two connecting support rods 32. The connecting rotating rod 30 is fixed to the connecting support rod 32 by bearings and can rotate freely. A central fan blade 31 is provided at the center of the connecting rotating rod 30. Both ends of the connecting rotating rod 30 are provided with transverse conical teeth 29 that cooperate with the vertical conical teeth 28. The tooth shape and angle of the vertical conical teeth 28 are precisely designed to achieve efficient meshing and transmission with the transverse conical teeth 29. Sealing auxiliary plates 1 are also provided on both sides of the sealed side box 9. 0. A sliding limit strip 26 is provided on one side surface of the sealing auxiliary plate 10. The auxiliary box 6 and the connecting main box 7 are provided on both sides with side sliding grooves 23 that cooperate with the sliding limit strip 26. A meshing frame 14 is also provided on one side surface of the connecting frame rod 16. The meshing frame 14 is a key component for transmitting the power of the drive motor 13. A motor mounting seat 12 is provided on the upper surface of the column 11. A drive motor 13 is provided on the upper surface of the motor mounting seat 12. The drive motor 13 is a high-performance servo motor with fast response speed and high control precision. A meshing screw 15 is provided on the output end of the drive motor 13. The meshing screw 15 meshes with the meshing frame 14.

[0035] The transmission assembly is used to transmit the airflow power discharged from the outlet duct 3 during the initial vacuum extraction of the vacuum pump body 2, thereby improving the speed and efficiency of the initial vacuum extraction. In use, the drive motor 13 is started by a signal from the operator. Through the meshing effect between the meshing frame 14 and the drive motor 13, the entire transmission assembly moves, causing the two sliding plates 18 to slide inside the sliding groove 17. This moves the two fan blades 19 to the outlet path of the outlet duct 3. At this time, the two sealed side boxes 9 also move synchronously under the drive of the connecting rod 16, moving the central fan blade 31 directly above the opening on the bottom surface of the main box 7 that connects to the main air supply pipe 33. During evacuation, the air discharged from the outlet duct 3 will... The fan blades 19 blow air, which drives the transmission wheel 21 via the transmission belt 20. When the transmission wheel 21 rotates, the rotating rod 22 also rotates, driving the vertical bevel teeth 28 at its end to rotate. Under the meshing action of the vertical bevel teeth 28 and the horizontal bevel teeth 29, the connecting rotating rod 30 is driven to rotate, causing the central fan blade 31 at its center to rotate synchronously, converting the linear airflow into a rotating vortex. The rotating vortex forms a stable airflow boundary layer, reducing the friction loss of the inner wall of the transfer box, allowing the mainstream gas to enter the pump body more smoothly, and accelerating the flow of gas from the box to the transfer box, thereby achieving a faster evacuation time. After the vacuuming work is completed, the transmission components are reset and returned to their original position under the reverse drive of the drive motor 13.

[0036] The working principle of this invention is:

[0037] During initial vacuuming, the operator issues a signal to start the drive motor 13. Through the engagement of the engagement screw 15 and the engagement frame 14, the transmission components move. The two sliding plates 18 slide in the sliding groove 17, causing the fan blades 19 to move to the air outlet path of the air outlet duct 3. At the same time, the sealing side box 9 moves the central fan blade 31 to the top of the opening connecting the bottom of the main box 7 and the main air supply pipe 33. The air discharged from the air outlet duct 3 drives the fan blades 19 to rotate. The transmission belt 20 causes the transmission wheel 21 to rotate, and the rotating rod 22 rotates accordingly. The vertical bevel teeth 28 and the horizontal bevel teeth 29 engage, causing the connecting rotating rod 30 to rotate. The central fan blade 31 rotates synchronously, converting the linear airflow into a rotating vortex, accelerating the flow of gas from the box to the transfer box, and increasing the vacuuming speed.

[0038] At the same time, the small motor 25 starts, the internal screw 39 rotates, causing the sliding block 37 to move and block the bottom of the auxiliary air supply pipe 34. The vacuum pump body 2 draws air from the inside of the main box 7 through the transfer box 5, and draws out the air in the storage box through the top air inlet 8, quickly forming a vacuum environment.

[0039] When the storage box leaks and needs to be evacuated again, the small motor 25 starts again, the sliding block 37 moves to block the main gas supply pipe 33, and the vacuum pump 2 draws gas from the inside of the auxiliary box 6 through the auxiliary gas supply pipe 34 to remove the residual gas that flowed in during the leak, ensuring the vacuum inside the auxiliary box 6, reducing the starting frequency of the vacuum pump 2, and reducing energy consumption. After the vacuuming is completed, all components are reset and ready for the next operation.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
