Description

Technical Field

[0001] This invention relates to the field of hybrid elevator breathing vacuum exhaust technology, and more particularly to a hybrid elevator breathing vacuum exhaust system. Background Technology

[0002] Stamping presses and pressure machines in steel coil stamping equipment are core equipment in manufacturing, used to stamp coils or sheets into parts such as automotive components and appliance housings under enormous pressure. Their working cycle typically includes three stages: rapid descent, stamping or holding pressure, and rapid return. During this process, the piston of the main hydraulic cylinder undergoes high-speed, high-flow reciprocating motion. The hybrid lifting platform's breathing vacuum exhaust system effectively manages gas and pressure fluctuations within the hydraulic system, ensuring smooth operation. Furthermore, in these devices, the hydraulic system is often the core control mechanism for the lifting platform's movements. The working principle of a hydraulic lifting platform is to generate force through the flow of liquid in a closed system to achieve lifting control.

[0003] Prior art, such as the invention disclosed in publication number CN102220981A, discloses a dry vacuum pump device, an exhaust unit, and a silencer. This patent includes a silencer that can be reduced in size to effectively reduce noise from the exhaust gas from the end outlet and intermediate release outlet of the dry vacuum pump over a wide frequency range from low to high frequencies. The dry vacuum pump device includes a dry vacuum pump having an end outlet and an intermediate release outlet, an exhaust section check valve connected to the end outlet and having an outlet, an intermediate section check valve connected to the intermediate release outlet and having an outlet, an exhaust passage connected to the outlet of the exhaust section check valve and the outlet of the intermediate section check valve, and a silencer connected to the exhaust passage and having an outlet, the outlet of which is connected to the end exhaust passage open to the atmosphere.

[0004] During industrial production, it has been found that many vacuum exhaust systems in hybrid elevators and vacuum exhaust technologies in steel coil stamping equipment fail to adequately filter the exhaust air. During high-speed stamping, forming, and separation processes, steel coil stamping equipment generates large amounts of metal dust, lubricant mist, and volatile organic pollutants released at high temperatures. If these exhaust gases are emitted directly without treatment, they will mix with the oil mist, dust, odors, and volatile organic compounds (VOCs) emitted by the hybrid elevator system, further exacerbating environmental pollution and harming the health of surrounding populations. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as vacuum exhaust systems for hybrid elevators and vacuum exhaust technologies for steel coil stamping equipment, which often fail to adequately filter the exhaust air. During the high-speed stamping, forming, and separation processes of steel coil stamping equipment, a large amount of metal dust, lubricant mist, and volatile organic pollutants generated at high temperatures are produced. If these exhaust gases are emitted directly without treatment, they will mix with the oil mist, dust, odors, and volatile organic compounds (VOCs) emitted by the hybrid elevator system, further exacerbating environmental pollution and harming the health of surrounding populations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hybrid elevator breathing vacuum exhaust system, comprising a frame, with legs fixedly connected to the four corner surfaces of the frame, a processor disposed on one end surface of the frame, two mounting brackets fixedly connected to both end surfaces of the frame, two vacuum pumps welded to the sides of the two mounting brackets, a vacuum frame fixedly connected to the middle surface of the frame, a controller disposed on one side of the upper surface of the vacuum frame, the output end of the vacuum pump being fixedly connected to the vacuum frame, a plurality of suction tubes being uniformly fixedly connected to the bottom surface of the vacuum frame, an exhaust pipe disposed on one side of the vacuum pump, a silencer assembly disposed at the upper end of the exhaust pipe, the silencer assembly comprising an outer shell, an inner shell fixedly connected inside the outer shell, a plurality of through holes being opened on the surface of the inner shell, sound-absorbing cotton (polyester fiber cotton) being disposed on the side of the outer shell and the inner shell close to each other, a connecting pipe being fixedly connected to the lower surface of the outer shell, and a filter assembly comprising a guide plate on the upper inner wall surface of the outer shell and the inner shell. The guide plate is fixedly connected to the inner wall of the inner shell. The guide plate has a circular cross-section. A fixing ring is fixedly connected to the upper end of the guide plate. A support frame slides through the inner wall of the fixing ring. Several filter strips are rotatably connected to the inner wall of the support frame. Fixing plates are fixedly connected to both sides of the upper surface of the support frame. A positioning ring is fixedly connected to one side of two fixing plates. Several connecting plates are fixedly connected to the inner wall surface of the positioning ring. Moving rods slide through the surface of the connecting plates. A pressing ring is fixedly connected to the upper end of several moving rods. A first spring is sleeved on the arc surface of the moving rod. The two ends of the first spring are fixedly connected to the moving rod and the connecting plate, respectively. Sliding rods are fixedly connected to both sides of the inner wall of the positioning ring. An insert block slides through the arc surface of the sliding rod. The bottom cross-section of the insert block is barbed. A second spring is sleeved on the arc surface of the sliding rod. The two ends of the second spring are fixedly connected to the insert block and the positioning ring, respectively. A retaining ring is fixedly connected to the surface of the fixing ring. The inner wall of the retaining ring engages with the surface of the insert block.

[0007] The effects achieved by the above components are: to effectively reduce airflow noise through the silencing component, to filter and purify the air through the filter component, and to make the installation and removal of the filter unit extremely convenient and easy to maintain.

[0008] Preferably, the insert includes an adjustment end with an inclined cross-section, and the pressing ring is provided with a pressing end on one side of the lower surface of the insert. The pressing end is wedge-shaped and abuts against the side surfaces of the pressing end and the adjustment end that are close to each other.

[0009] The effect achieved by the above components is as follows: by setting a wedge-shaped pressing end and an inclined adjusting end, the vertical downward movement of the pressing ring is efficiently converted into the horizontal radial movement of the insert block by utilizing the principle of inclined plane, making the unlocking process less strenuous and smoother, and improving the convenience of operation.

[0010] Preferably, side plates are fixedly connected to both sides of the arc surface of the slide rod, and the surface of the side plates slides through the surface of the inlay block.

[0011] The effect achieved by the above components is that the side plate limits and guides the movement of the insert block, preventing it from deflecting or getting stuck during sliding, and ensuring the stability and reliability of locking and unlocking actions.

[0012] Preferably, the filter strip has a cross-shaped fan blade design, and the filter strip is an activated carbon strip.

[0013] The aforementioned components achieve the following effects: the cross-shaped fan-shaped design significantly increases the specific surface area of ​​the filter strips, thereby improving air purification efficiency. Using activated carbon as the material allows it to effectively adsorb chemical pollutants and odors in the air, improving the quality of the exhaust air.

[0014] Preferably, the straw has a docking assembly on its arc surface. The docking assembly includes two docking frames with arc-shaped cross-sections. The inner walls of the docking frames abut against the arc surface of the straw. A limiting frame is fixedly connected to the surface of the docking frames. A limiting block is fixedly connected to the end of the limiting frame away from the docking frames. The inner wall of the limiting block is U-shaped. A limiting post is fixedly connected to the lower surface of the mounting frame at the position corresponding to the limiting block. A limiting shaft is threadedly connected to the arc surface of the limiting post. Auxiliary grooves are provided on the sidewall surfaces at both ends of the two docking frames. The same auxiliary frame is inserted into the inner wall of the two auxiliary grooves. The auxiliary frame has a U-shaped cross-section.

[0015] The aforementioned components achieve the following effects: the support assembly holds the suction tube tightly from both sides through two docking frames, and then, through the cooperation of the limiting frame, limiting block, and limiting post and limiting shaft on the mounting frame, the suction tube is stably suspended and fixed below the mounting frame, effectively preventing it from shaking; at the same time, by inserting the auxiliary frame into the auxiliary slots on both sides, the two docking frames are connected into a whole, which greatly enhances the rigidity and stability of the support structure.

[0016] Preferably, a second rotating frame is rotatably connected to both sides of the auxiliary frame, a telescopic rod is fixedly connected to the upper surface of the second rotating frame, a first rotating frame is rotatably connected to both ends of the telescopic rod, the same top plate is fixedly connected to the two first rotating frames that are close to each other, a third spring is sleeved on the arc surface of the telescopic rod, and the two ends of the third spring are fixedly connected to the first rotating frame and the second rotating frame respectively, and the lower surface of the top plate abuts against the side wall surfaces of the two docking frames.

[0017] The effect achieved by the above components is as follows: Under the elastic force of the third spring, the top plate continuously presses down on the two docking frames to ensure that they are always in close contact with the straw and provide a stable clamping force. During this process, the first rotating frame, the second rotating frame and the telescopic rod form a movable linkage mechanism, which allows the top plate to adaptively adjust its position within a certain range while ensuring the transmission of the clamping force.

[0018] Preferably, both sides of the two docking frames are provided with fixing grooves, and the inner walls of the two fixing grooves are engaged with the lower surface of the top plate.

[0019] The effect achieved by the above components is that the fixing groove engages with the lower end of the top plate, further restricting the displacement of the docking frame, preventing it from sliding on the suction tube, and enhancing the stability of the support.

[0020] Preferably, a friction pad is fixedly connected to the inner wall of the docking frame on the side near the straw. The friction pad is a rubber pad, and the surface of the friction pad abuts against the arc surface of the straw.

[0021] The aforementioned components achieve the following effects: the rubber friction pad increases the friction between the docking frame and the straw surface, making the clamping more secure. Simultaneously, the elasticity of the rubber protects the straw surface from scratches and absorbs some vibration.

[0022] Preferably, a support assembly is provided on the arc surface of the connecting pipe corresponding to the position of the air outlet pipe. The support assembly includes a rotating ring, the inner wall of which is threadedly connected to the arc surface of the connecting pipe. An adjusting frame is rotatably connected to one side of the rotating ring. The inner wall of the adjusting frame is movably connected to the arc surface of the connecting pipe. Four extrusion shafts are threaded evenly through the arc surface of the adjusting frame. A support block is fixedly connected to the arc surface of the air outlet pipe. The cross-sectional dimensions of the adjusting frame are adapted to the cross-sectional dimensions of the support block. A positioning hole is provided on the arc surface of the support block. The inner wall of the positioning hole is threadedly connected to the arc surface of the extrusion shaft.

[0023] The above components achieve the following effects: the docking assembly provides a robust and sealed pipe connection method, while facilitating installation and disassembly. By rotating the adjustment frame, it can move along the rotating ring to initially fit the support block on the vent pipe. Tightening the four extrusion shafts will cause them to penetrate into the positioning holes on the support block, thereby tightening and fixing the connecting pipe and the vent pipe to ensure airtightness of the connection.

[0024] Preferably, a positioning frame is fixedly connected to the lower surface of the outer shell, and a plurality of insert blocks are fixedly connected to the lower surface of the positioning frame. The arc surface of the support block has a slot corresponding to the position of the insert block. The inner wall of the slot is inserted into the surface of the insert block. A base plate is fixedly connected to the lower surface of the support block, and the surface of the base plate abuts against the lower surface of the insert block.

[0025] The effects achieved by the above components are as follows: the cooperation between the insert and the slot, as well as the bottom plate limiting, realizes rapid initial positioning and circumferential limiting, preventing relative rotation between the adjusting frame and the support block during the tightening of the extrusion shaft, making the installation alignment more accurate and convenient. The bottom plate also provides additional bottom support for the entire connection part, enhancing the structural stability.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] 1. In this invention, by setting up a filter assembly and utilizing a quick-locking and releasing mechanism composed of a pressing ring, insert block, spring, and retaining ring, the filter unit can be disassembled and installed without tools with a single click. This design is particularly suitable for the harsh working conditions of steel coil stamping equipment, which generates a large amount of metal dust and oil mist during production. It greatly simplifies the process of frequent maintenance, cleaning, or replacement of filter strips in the later stages, while ensuring the stability and airtightness after installation. This ensures the efficient and continuous stable operation of the stamping equipment exhaust gas treatment system, helps to thoroughly filter and purify the gas discharged from the outlet pipe, greatly improves the workshop working environment, and is beneficial to energy conservation and environmental protection.

[0028] 2. In this invention, by setting up a support component, two connecting frames embrace the suction tube from both sides and connect them into a whole through an auxiliary frame. The limiting blocks and limiting posts then lock the tube in place, providing multi-point, uniform, and robust auxiliary support for the slender suction tube. This structure effectively copes with the strong vibrations and noise generated by the steel coil stamping equipment during high-speed stamping, effectively suppressing the shaking and deformation of the pipe caused by vibration, preventing fatigue fracture and loosening of the joints due to long-term pipe vibration, and significantly improving the stability and service life of the dust removal system and even the entire stamping equipment.

[0029] 3. In this invention, a robust and reliable connection between the connecting pipe and the exhaust pipe is achieved by setting up a docking assembly and rotating the adjustment frame and tightening multiple extrusion shafts. This connection method can withstand the pressure fluctuations that may occur in the exhaust gas system of the steel coil stamping equipment. It not only ensures high sealing at the connection point, preventing the leakage of harmful gases and dust, but its standard threaded connection also facilitates rapid installation of the pipeline and regular disassembly and maintenance in the future. This greatly facilitates preventive maintenance and cleaning of the equipment, and the operation is simple and convenient, reducing downtime. Attached Figure Description

The inner wall of each docking frame 705 abuts against the arc surface of the straw 9. A limiting frame 701 is fixedly connected to the surface of each docking frame 705.

[0048] like Figure 8 As shown, a support assembly 6 is provided on the arc surface of the connecting pipe 84 corresponding to the position of the air outlet pipe 13. The support assembly 6 includes a rotating ring 68, the inner wall of which is threadedly connected to the arc surface of the connecting pipe 84. An adjusting frame 63 is rotatably connected to one side of the rotating ring 68. The inner wall of the adjusting frame 63 is movably connected to the arc surface of the connecting pipe 84. Four extrusion shafts 66 are evenly threaded through the arc surface of the adjusting frame 63. A support block 61 is fixedly connected to the arc surface of the air outlet pipe 13.

The surface of the base plate 69 abuts against the lower surface of the insert block 65.

[0049] The overall working principle is as follows: After the system is started, the vacuum pump 3 located below the steel coil stamping equipment begins to work. After the upper and lower dies of the stamping equipment complete the stamping operation on the steel coil, waste material and oil vapor mixture are generated. If evacuation is required, the vacuum pump 3 draws the waste gas containing metal dust and oil mist generated in the stamping area into the vacuum frame 4 through the suction pipe 9; if exhaust is required, the vacuum pump 3 pumps the air in the system into the vacuum frame 4 and discharges it outward through the suction pipe 9. Multiple evenly distributed suction pipes 9 ensure the uniformity and efficiency of airflow, effectively capturing pollutants generated during the stamping process. The airflow eventually enters the silencer assembly 8 through the exhaust pipe 13 on one side of the vacuum pump 3. The airflow first enters the inner shell 82 and diffuses through the through holes on its surface into the cavity between the outer shell 81 and the inner shell 82. The polyester fiber sound-absorbing cotton 83 in the cavity effectively absorbs the sound wave energy generated by the airflow, thereby significantly reducing the noise generated when the vacuum pump is working and providing a relatively quiet environment for the production workshop. After noise reduction, the airflow, which may contain fine oil mist particles, continues to flow upwards, passing through filter assembly 5. Guide plate 505 directs the airflow evenly through filter strips 504 fixed by support frame 503. Activated carbon filter strips 504 effectively adsorb oil mist contaminants and odor molecules on their surface, purifying the air from the stamping process. The purified air is ultimately discharged from the system, either directly back to the workshop or discharged outdoors according to regulations, ensuring environmental compliance. Support assembly 6 provides stable auxiliary support for the exposed suction pipe 9, preventing it from shaking or being damaged by vibrations from the vacuum pump and stamping equipment, ensuring unobstructed airflow. Filter assembly 5 can be easily locked and removed by pressing, greatly facilitating the periodic cleaning or replacement of filter strips 504, which is crucial for treating industrial oil contamination and ensures long-term filtration efficiency. The system uses a vacuum pump 3 to drive airflow, closely coordinating with the production rhythm of the steel coil stamping equipment. It promptly draws in and processes the stamping exhaust gas, guiding it sequentially through a suction pipe 9, a vacuum frame 4, a silencer assembly 8, and a filter assembly 5. This completes the entire process from industrial exhaust gas collection, transportation, noise reduction, to purification. Various supporting and connecting structures ensure that the entire system can work in conjunction with the stamping equipment, operating stably, quietly, and efficiently over the long term.

[0050] During this process, to facilitate the replacement of the limit position of the filter assembly 5, the entire filter assembly 5 is aligned with the lower retaining ring 501 and inserted. When placed downwards, the barbed bevel at the bottom of the insert block 512 will contact the inner edge of the retaining ring 502. Continuing to press downwards, the force on the bevel will force the insert block 512 to contract inwards, compressing the second spring 516. After the insert block 512 passes the retaining ring 502, the rebound force of the second spring 516 will immediately push the insert block 512 outwards, making it firmly locked under the inner wall of the retaining ring 502. At this point, the entire filter assembly 5 is firmly locked in the working position and cannot fall off on its own, ensuring stability and sealing during operation. Under the action of the first spring 511, the pressing ring 507 and the moving rod 510 assembly remain in the upper limit position, ready for the next pressing operation. When it is necessary to replace or clean the filter strip 504, simply press the pressing ring 507 downwards. As the pressing ring 507 moves downwards, its bottom wedge-shaped pressing end 514 will contact the inclined adjustment end 513 at the upper end of the insert block 512. As the pressure continues to be applied, this inclined structure will generate a lateral component force, pushing the insert block 512 to overcome the elastic force of the second spring 516 and retract inwards, causing it to disengage from the snap ring 502. When all insert blocks 512 have disengaged from the snap ring 502, the entire filter assembly 5 is in the unlocked state and can be easily removed upwards. After releasing the pressing ring 507, the first spring 511 will cause the pressing ring to spring back to the initial position, waiting for the next operation.

[0051] To effectively support and fix the entire straw 9, two arc-shaped docking frames 705 are brought together from both sides of the straw 9, so that the rubber friction pads 706 on their inner walls tightly wrap around the arc surface of the straw 9, forming a complete annular support structure. An auxiliary frame 709 is inserted into the auxiliary grooves 707 on the side walls at both ends of the two docking frames 705, connecting and locking the two independent docking frames 705 into a unified, rigid whole, preventing separation under stress and greatly enhancing structural stability. The limiting brackets 701 and limiting blocks 702 connected to the docking frames 705 are aligned and engaged with the limiting posts 703 fixed to the lower surface of the mounting bracket 2. The limiting posts 703 fit precisely into the "U"-shaped groove of the limiting blocks 702, thus initially suspending and positioning the entire support assembly 6 in the designated installation position. Finally, the limiting shaft 704 is screwed into the threads of the limiting posts 703 and tightened. One end of the limiting shaft 704 will press against the limiting block 702, thereby locking it firmly onto the limiting post 703, completing the fixed connection between the entire support assembly 6 and the main frame 1 of the system.

[0052] When aligning and positioning the entire muffler assembly 8, the lower end of the connecting pipe 84 is fitted onto the upper end of the exhaust pipe 13. At this time, the insert 65 at the bottom of the positioning bracket 64 fixed to the lower surface of the housing 81 will insert into the corresponding slot 62 on the support block 61, preventing relative rotation between the muffler assembly 8 and the exhaust pipe 13 during subsequent operations, ensuring that all connecting parts can be accurately aligned. Rotate the adjusting frame 63 fitted onto the connecting pipe 84. Since the adjusting frame 63 is rotatably connected to the rotating ring 68, and the rotating ring 68 is threadedly connected to the connecting pipe 84, rotating the adjusting frame 63 will cause it to move downward along the axis of the connecting pipe 84, moving forward or backward like a nut. Rotate the adjusting frame 63 downward so that its inner wall fits and surrounds the support block 61 at the upper end of the exhaust pipe 13. After the adjusting frame 63 is in place, tighten the four extrusion shafts 66 evenly distributed on the arc surface of the adjusting frame 63 in sequence. These pressing shafts 66 are screws that push inward when screwed in, and the inner end of the pressing shaft 66 screws into and presses tightly against the positioning hole 67 on the support block 61. By evenly tightening multiple pressing shafts 66, the powerful thread pressure can be used to tightly pull the adjusting frame 63, the support block 61 and the connecting pipe 84 together to form a rigid and well-sealed connection.
