Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vacuum pumps, in particular to an energy-saving device for a vacuum pump. BACKGROUND

[0002] In modern industrial production and many technical application fields, vacuum environment plays a crucial role. From high-precision vacuum coating in the process of electronic chip manufacturing, to vacuum packaging technology used in the food packaging industry to extend the shelf life, to the control of vacuum conditions required for specific chemical reactions in the chemical industry, as the core equipment for creating and maintaining a vacuum environment, the performance and efficiency of vacuum pumps directly affect the quality, cost and energy consumption of production. With the global emphasis on energy saving and emission reduction and the continuous rise of energy costs, improving the energy utilization efficiency of vacuum pumps has become a key direction for industry development.

[0003] The existing vacuum pump technology has some inconveniences. In the actual application process of the vacuum pump, the storage tank body leaks due to various reasons. The existing vacuum pump technology lacks an effective buffer mechanism in this regard and cannot reasonably and accurately control the internal pressure change of the storage tank body. When the storage tank body leaks, the internal pressure will change rapidly, and the original stable vacuum environment will be destroyed. Since there is no buffer mechanism to balance the pressure, the vacuum pump can only be frequently started and stopped in order to maintain the set vacuum degree. Each time the vacuum pump is started, it needs to consume a large amount of electric energy to overcome the initial resistance to reach the normal working state. Frequent stopping and restarting will cause the motor and other key components to bear a large current impact and mechanical stress. This frequent start-stop not only greatly increases energy consumption, resulting in a significant increase in use cost, but also accelerates the wear and tear of internal parts of the vacuum pump. In addition, in the working process of the vacuum pump, the flow of gas from the storage tank body to the pump body mainly relies on the suction force of the vacuum pump. This single suction method makes the gas flow slow, especially when the vacuum is first extracted. It takes a long time to extract the air in the storage tank body to form the required vacuum environment. In industrial production, the waste of time means a decrease in production efficiency, which may affect the progress of the entire production process. Moreover, the long pumping time also causes the vacuum pump to be in a high-load running state for a long time, further increasing energy consumption and equipment wear and tear. SUMMARY

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0017] Embodiment 1: Please refer to Figures 1 to 8 A vacuum pump energy-saving device, comprising: The base 1 is made of high-strength and wear-resistant alloy material, which is cast, and its surface is finely treated and polished to have good corrosion resistance and ensure flatness and stability during long-term use. The upper surface of the base 1 is provided with a stand 11 made of high-quality steel, which has sufficient strength and rigidity to withstand the weight of the vacuum pump body 2 and related components and various forces generated during operation. One side surface of the stand 11 is provided with a vacuum pump body 2, which is the core power component of the entire system. The bottom surface of the vacuum pump body 2 is provided with an air outlet pipe 3, and the upper surface of the vacuum pump body 2 is further provided with an air inlet pipe 4, which is the channel for air entering the vacuum pump body 2. The upper surface of the vacuum pump body 2 is further provided with an auxiliary mechanism, which is designed to further optimize the working performance of the vacuum pump. The auxiliary mechanism includes a gas box assembly and an air duct assembly. The air duct assembly includes a transfer box 5, which plays a key role in air distribution and adjustment. The bottom surface of the transfer box 5 is connected to the upper surface of the air inlet pipe 4, and the connection is sealed with rubber gaskets and bolted to ensure that the connection does not leak. The two side surfaces of the transfer box 5 are respectively provided with a side additional block 40 and a side additional box 24. The upper surface of the side additional block 40 is provided with a limiting slide 41, and the inside of the side additional box 24 is provided with a small motor 25. The output end of the small motor 25 is provided with an internal screw 39, which is located inside the transfer box 5. The inside bottom surface of the transfer box 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 and the sliding side plates 38 on both sides of the sliding block 37 are matched. The two side surfaces of the sliding block 37 are provided with sliding side plates 38 matched with the internal sliding groove 36. The upper surface of the transfer box 5 is provided with a main gas conveying pipe 33 and a vice gas conveying pipe 34, and the inside upper surface of the transfer box 5 is provided with two limiting arc plates 35 corresponding to the main gas conveying pipe 33 and the vice gas conveying pipe 34. In use, the worker connects the top air inlet 8 with the storage box body which needs to be vacuumized, the air passage assembly is used to connect the vacuum pump body 2 with the air box assembly, and the air suction path of the vacuum pump body 2 is adjusted according to the specific situation, so as to meet different use requirements. In use, the air passage assembly completes the circulation of gas through the bottom air inlet pipe 4, the top main gas conveying pipe 33 and the auxiliary gas conveying pipe 34. In order to ensure the efficiency of vacuumization, the small motor 25 is started by the worker signal driving in the initial vacuumization, the sliding block 37 is moved by the meshing action of the internal screw rod 39 and the sliding block 37, and the bottom of the auxiliary gas conveying pipe 34 is blocked. At this time, the vacuum pump body 2 sucks air from the inside of the connected main box body 7 through the transfer box body 5, and sucks the air in the storage box body which needs to be vacuumized through the top air inlet 8, so as to quickly form a vacuum environment. When the detector in the storage box body detects that leakage occurs after a period of use, and air needs to be extracted again, the sliding block 37 is moved below the main gas conveying pipe 33 by the above-mentioned way, and the main gas conveying pipe 33 is blocked. At this time, when extracting again, the vacuum pump body 2 extracts from the inside of the additional box body 6 through the auxiliary gas conveying pipe 34, so as to extract the residual gas in the additional box body 6 when the storage box body leaks when the inside of the storage box body is kept vacuum again, so as to ensure that the inside of the additional box body 6 keeps vacuum state, so that the air box assembly can work normally.

[0018] The gas box assembly comprises a connecting main box 7, which is the core main body part of the gas box assembly and is made of high-strength and light-weight alloy material. The upper surface of the connecting main box 7 is provided with a top air inlet 8. The bottom surface of the connecting main box 7 is connected to the upper surface of a main gas conveying pipe 33. One side surface of the connecting main box 7 is provided with an additional box 6, and the bottom surface of the additional box 6 is connected to the upper surface of a secondary gas conveying pipe 34. Both side surfaces of the connecting main box 7 are provided with side openings 42, which are used to increase the movement range of the transmission assembly. The inner bottom surface of the connecting main box 7 is provided with an opening that is in communication with the main gas conveying pipe 33. The inner bottom surface of the connecting main box 7 is further provided with a secondary electric sealing plate 43 and a main electric sealing plate 44. The secondary electric sealing plate 43 and the main electric sealing plate 44 are provided with electric shafts at the connecting positions with the connecting main box 7. The upper surface of the main electric sealing plate 44 is provided with a plurality of top protrusions 45. An inner partition plate 46 is arranged between the connecting main box 7 and the additional box 6. The inner partition plate 46 divides the connecting main box 7 and the additional box 6 into two relatively independent spaces, but realizes limited flow of air through a specific structure. The center of the inner partition plate 46 is provided with a sealing diaphragm 47, which is made of high-elasticity and wear-resistant rubber material and has good sealing performance and flexibility. It can prevent the air flow between the connecting main box 7 and the additional box 6 from directly mixing during normal operation. Only under specific conditions, such as when the movable sealing strip 49 moves, the sealing diaphragm 47 will deform to allow a small amount of air flow. The surface of the inner partition plate 46 is further provided with a plurality of fixed connecting blocks 48 for fixing the sealing diaphragm 47. The fixed connecting blocks 48 are fixed on the inner partition plate 46 by bolts or welding, which ensures that the sealing diaphragm 47 will not loosen or shift during operation. The center of the inner partition plate 46 is further provided with two movable sealing strips 49, which are key components for controlling the deformation of the sealing diaphragm 47 and the passage of air flow. The surface of the fixed connecting block 48 is provided with a plurality of air passages 51, which provide a passage for air flow when the sealing diaphragm 47 deforms. The side surface of the movable sealing strip 49 away from the air passage 51 is further provided with a connecting additional block 52. The side surface of the connecting additional block 52 is provided with a connecting spring 53, which is connected to the side surface of the inner partition plate 46. The side surface of the movable sealing strip 49 is further provided with a stress protrusion 50 that cooperates with the top protrusion 45. The gas box assembly is used to reduce the leakage effect of the additional box 6 when the storage box body leaks, reduce the starting frequency of the vacuum pump body 2, so as to achieve the effect of reducing energy consumption. When the initial extraction is carried out, the vacuum pump body 2 extracts the vacuum of the storage box body through the connecting main box 7. In this process, the auxiliary electric sealing plate 43 and the main electric sealing plate 44 are rotated and turned up under the action of the electric shaft, and the opening on the bottom surface of the connecting main box 7 which is communicated with the main gas pipe 33 is exposed. At this time, the main electric sealing plate 44 is in the vertical state, the four top convex blocks 45 are in contact with the stress convex blocks 50 on the two movable sealing strips 49, and the whole movable sealing strip 49 is pushed to one side, and the connecting spring 53 is stretched. At this time, the connecting main box 7 and the additional box 6 are communicated through the air vent groove 51. At this time, in the case of vacuumizing, the inside of the additional box 6 can also be vacuumized. When the vacuumizing 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 sealing strip 49 loses the top touch effect of the top convex block 45 and is reset under the action of the connecting spring 53. The inside of the partition plate 46 is closed through the two movable sealing strips 49. At this time, when the inside of the storage box body leaks, the pressure inside it increases, and the sealing diaphragm 47 will deform to one side of the additional box 6 under the action of the pressure difference on both sides. The fixed connecting block 48 can prevent it from being separated from the inside partition plate 46. When the sealing diaphragm 47 deforms to a certain extent, the position of its edge not connected will be separated from the surface of the inside partition plate 46, and the gap will be exposed. At this time, the vacuum inside the additional box 6 will diffuse to the main box, offset part of the air leakage, so as to reduce the starting frequency of the vacuum pump body 2, and achieve the effect of reducing energy consumption.

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. The transmission assembly is used for conducting the air flow power discharged from the air outlet pipeline 3 when the vacuum pump body 2 is used for primary vacuum extraction, so as to improve the speed and efficiency of the primary vacuum extraction. In use, the driving motor 13 is started by the signal of the staff, the whole transmission assembly is moved through the meshing effect of the meshing frame body 14 and the driving motor 13, the two sliding plate bodies 18 slide in the sliding grooves 17, so that the two air moving fan blades 19 are moved to the air outlet path of the air outlet pipeline 3.

At this time, when the air is extracted, the air discharged from the air outlet pipeline 3 blows the two air moving fan blades 19, and the transmission belt 20 drives the transmission wheel 21. When the transmission wheel 21 rotates, the rotating rod body 22 also rotates, and drives the vertical bevel gear 28 at the tail end to rotate. Under the meshing effect of the vertical bevel gear 28 and the horizontal bevel gear 29, the connecting rotating rod 30 is driven to rotate, so that the central fan blade 31 at the center is also synchronously rotated, the linear air flow is converted into a rotating vortex, the rotating vortex forms a stable air flow boundary layer, the friction loss of the inner wall of the transfer box is reduced, the main flow gas more smoothly enters the pump body, the gas flow from the box to the transfer box is accelerated, so that the extraction time is faster.
