Description

Technical Field

[0001] The invention relates to the technical field of air suspension blowers, in particular to a high-efficiency and energy-saving air suspension blower. Background Art

[0002] The air suspension blower is a new type of high-efficiency and energy-saving blower. The air suspension blower uses air bearing technology to make the impeller shaft suspended in the air when rotating at high speed. There is no need for traditional mechanical bearings. Specifically, the air is compressed by an air compressor and sent into the bearing system to form a uniform air film between the impeller shaft and the bearing. This air film not only plays a supporting role, allowing the impeller shaft to rotate at high speed without contact, but also plays a lubricating role to reduce friction loss. At the same time, the motor drives the impeller to rotate at high speed, so that the air is accelerated and guided through the impeller to generate a strong airflow, thereby realizing the gas transportation and pressurization functions.

[0003] In the aeration process of the sewage treatment plant, the air suspension blower provides sufficient oxygen for the activated sludge process to ensure the normal metabolism of microorganisms and the effective decomposition of pollutants. It is used in gas transportation, pressurization, oxidation and other process in chemical production, such as synthetic gas transportation in fertilizer production, air supply for catalytic cracking units in petrochemicals, etc. In the production processes of electronic chip manufacturing and liquid crystal display, high-purity, oil-free compressed air is required. The air suspension blower can meet the strict requirements of these processes on gas quality and provide a stable gas source for production equipment. In food fermentation, beverage filling and other processes, the air suspension blower can provide clean and sterile air for ventilation and stirring in the fermentation process, blow molding of beverage bottles and other links to ensure product quality and production safety. In the air purification, material transportation, fermentation and other process links in the pharmaceutical production process, the air suspension blower can provide clean air that meets the requirements of the pharmaceutical production quality management specifications to ensure the cleanliness and stability of the pharmaceutical production environment.

[0004] The impeller of the air suspension blower is usually installed on a high-speed rotating main shaft, and is driven by a motor through a coupling or directly. The powerful power provided by the motor makes the impeller rotate at an extremely high speed, generally up to tens of thousands of revolutions per minute or even higher. When the impeller rotates, a low-pressure area will be formed in the center of the impeller. Since the gas has the characteristic of flowing from the high-pressure area to the low-pressure area, the outside air is sucked into the center of the impeller under the action of atmospheric pressure. After acceleration and pressurization, the gas is discharged from the edge of the impeller and enters the volute of the blower. In the volute, part of the kinetic energy of the gas is further converted into pressure energy, which further increases the gas pressure, and then is transported to the required place through the air outlet.

[0005] When the existing air suspension blower is in use, outside air is drawn into the casing, and the filter at the air inlet is used to block the dust and impurities contained in the air. Since the accumulation of dust will affect the efficiency of the air intake, it is generally necessary to remove the filter for cleaning, but it still needs to be shut down for maintenance, which is not conducive to the continuity of the blower's operation. Summary of the invention

[0006] The purpose of the present invention is to provide an efficient and energy-saving air suspension blower to solve the problem mentioned in the above background technology that the accumulation of dust will affect the efficiency of air intake, and the filter generally needs to be removed for cleaning, but it still needs to be shut down for maintenance, which is not conducive to the working continuity of the blower.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an efficient and energy-saving air suspension blower, comprising a blower body, a first connecting pipe is fixedly installed on the surface of the air inlet of the blower body, two filter air ducts are fixedly arranged on one end of the first connecting pipe, and the other ends of the two filter air ducts are fixedly connected to the second connecting pipe, the outer surface of the filter air duct is fixedly connected to a first mounting block, an adjusting cylinder is installed through the surface of the first mounting block, one end of the adjusting cylinder is fixedly connected to a limiting block, a supporting cylinder is installed through the limiting block and the adjusting cylinder, and the supporting cylinder One end of the rotating shaft is fixedly connected to an adjusting baffle, a positioning baffle is installed on the outer surface of one end of the adjusting cylinder, the outer surface of the filter air duct is fixedly connected to a second mounting block, an auxiliary telescopic air bag is fixedly connected between the outer surface of the filter air duct and the positioning baffle, the side surface of the first mounting block is provided with an opening, and a locking card block is installed on the inner wall of the opening of the first mounting block, one end of the locking card block is fixedly connected to an unlocking handle, the outer surface of the filter air duct is provided with an opening, and the inner wall of the opening of the filter air duct is provided with a positioning connecting plate, and one end of the positioning connecting plate is fixedly connected to a filter mounting frame.

[0008] Preferably, the first connecting tube and the second connecting tube are of Y-shaped design, one end of the inner wall of the first mounting block is of cylindrical design, and one end of the cylindrical inner wall of the first mounting block is provided with a rectangular groove, and the adjusting cylinder is rotatably connected with the positioning baffle.

[0009] By adopting the above technical solution, the Y-shaped structure can more reasonably distribute the medium flow rate flowing through the two connecting pipes. When the medium flows in from the upstream of the pipeline, the Y-shaped fork can divert the medium to the first connecting pipe and the second connecting pipe more evenly according to actual use requirements, avoiding the situation where the local pressure is too large or too small due to uneven flow distribution, thereby ensuring the stability of the operation of the entire pipeline system. One end of the inner wall of the first mounting block is carefully designed into a cylindrical shape. Such a cylindrical design has many uses. The cylindrical inner wall can provide a stable and smooth support and movement space for the components that cooperate therewith. When a component needs to rotate or slide in the first mounting block, the cylindrical inner wall can effectively reduce friction resistance and ensure the smooth movement of the component.

[0010] Preferably, the limiting block is designed as a rectangular parallelepiped, and the width of the limiting block is smaller than the width of the rectangular parallelepiped slot in the inner wall of the first mounting block.

[0011] By adopting the above technical scheme, the rectangular design is easy to process and form. In industrial production, whether it is cast, forged or machined, it is relatively simple to manufacture the rectangular limit block, which can improve production efficiency and reduce production costs. The rectangular shape makes the limit block have a clear directionality and positioning reference. The width of the limit block is specially designed to be smaller than the width of the rectangular groove in the inner wall of the first mounting block. This provides a certain space margin for the installation and movement of the limit block in the rectangular groove. The smaller width allows the limit block to be placed in the slot more easily, thereby improving the success rate of installation.

[0012] Preferably, a slider is provided at one end of the supporting cylinder, and the supporting cylinder is slidably connected to the adjusting cylinder, the adjusting baffle is rotatably connected to the filtering air duct, and the cavity of the auxiliary telescopic airbag is communicated with the filtering air duct.

[0013] By adopting the above technical solution, the existence of the slider gives the supporting cylinder a unique movement characteristic. This sliding ability allows the supporting cylinder to be adjusted in position according to the actual needs of the device, so as to better adapt to different working scenarios and changes in working conditions. The filter air duct undertakes the important task of guiding and filtering the gas in the entire device, and the rotation of the adjusting baffle can accurately control the flow rate, flow direction and flow rate of the gas. This rotating connection method enables the device to flexibly adjust the gas delivery and filtration effects according to actual needs, thereby improving the functionality and adaptability of the device.

[0014] Preferably, the locking block is slidably connected to the first mounting block, and the outer surface of one end of the locking block is inclined, the unlocking handle is slidably connected to the first mounting block, and a spring is connected between the locking block and the first mounting block.

[0015] By adopting the above technical scheme, the sliding connection formed between the locking block and the first mounting block provides the device with flexible locking and unlocking functions. When a certain component needs to be locked and connected with the first mounting block, the inclined surface can automatically adjust the angle and position during the contact process, so that the locking block can smoothly slide into the locked position. The inclined surface can also disperse the impact force generated during the locking process to avoid damage to components due to instantaneous strong impact, thereby extending the service life of the device. The unlocking handle and the first mounting block also form a sliding connection. The existence of the unlocking handle provides a convenient way for the unlocking operation. There is a sliding structure adapted to it on the first mounting block to ensure that the unlocking handle can slide along a specific trajectory.

[0016] Preferably, a linkage fastening mechanism is installed in the second mounting block, which drives the linkage gear and the connecting arm to rotate through the transmission tooth plate to facilitate locking the pressing block to press the positioning connecting plate and the filter screen mounting frame.

[0017] By adopting the above technical solution, the tooth shape of the transmission tooth plate is precisely processed and has a high degree of accuracy and surface finish. These teeth mesh with the teeth on the linkage gear to form an efficient transmission relationship. This meshing transmission method can achieve stable and accurate motion conversion, converting linear motion into circular rotation of the linkage gear. One end of the connecting arm is tightly connected to the linkage gear. When the linkage gear rotates, the connecting arm will also make circular motion around the axis of the linkage gear. When the connecting arm drives the locking block to move to a specific position, the locking block will accurately press on the positioning connecting plate and the filter mounting frame.

[0018] Preferably, the linkage fastening mechanism includes a transmission tooth plate, which is fixedly connected to the outer surface of one end of the positioning baffle, and a linkage gear is installed on the inner wall of the second mounting block. The outer surface of the second mounting block is provided with two connecting rotating arms, and one end of the two connecting rotating arms is fixedly connected with a locking pressure block.

[0019] By adopting the above technical solution, the transmission tooth plate is fixedly connected to the outer surface of one end of the positioning baffle in a firm and precise manner. The positioning baffle itself plays a positioning and supporting role in the entire mechanical system. When the positioning baffle moves under the action of external driving force, the transmission tooth plate closely connected thereto will move synchronously. The linkage gear is installed on the shaft on the inner wall of the second mounting block through a high-precision shaft hole, and strict assembly and debugging are carried out during the installation process to ensure that it can rotate flexibly and achieve precise meshing with the transmission tooth plate. When the transmission tooth plate makes a linear motion, its teeth interact with the teeth of the linkage gear to convert the linear motion into circular rotation of the linkage gear.

[0020] Preferably, one end of the transmission tooth plate passes through the second mounting block, and the transmission tooth plate and the second mounting block form a sliding connection, a tooth block is provided on the surface of the transmission tooth plate, and the transmission tooth plate is rotationally connected with the linkage gear through the tooth block, the rotating shaft of the linkage gear is fixedly connected to the rotating shafts of the two connecting arms, and the locking pressure block is L-shaped.

[0021] By adopting the above technical scheme, the channel reserved for the transmission tooth plate on the second mounting block has its inner wall finely ground and polished, and its surface roughness is extremely low to ensure that the transmission tooth plate can slide smoothly therein, and the transmission tooth plate is rotationally connected with the linkage gear through these tooth blocks. When the transmission tooth plate makes a linear motion in the second mounting block, its tooth blocks interact with the teeth of the linkage gear to convert the linear motion into a circular rotation of the linkage gear. When the linkage gear makes a circular motion driven by the transmission tooth plate, the rotating shaft of the connecting arm fixedly connected thereto will also rotate synchronously, thereby driving the connecting arm to swing around the rotating shaft. Driven by the connecting arm, after the locking pressure block moves to the specified position, one of its L-shaped surfaces can fit tightly with a plane of the target component, and the other surface can limit and fix the side of the target component, thereby achieving an all-round fastening effect.

[0022] Preferably, the outer surface of the filter air duct is provided with a groove, and a linkage piston column is installed on the inner wall of the filter air duct groove, a connecting air guide groove is opened on the inner wall of the filter air duct groove, and two sealing air bags are fixedly connected to the inner wall of the filter air duct cavity.

[0023] By adopting the above technical scheme, a linkage piston column is carefully installed on the inner wall of the filter air duct groove, and a close and flexible matching relationship is formed between the linkage piston column and the inner wall of the groove. One end of the linkage piston column is connected to an external power mechanism. When the power mechanism is in action, it can push the linkage piston column to make a linear motion in the groove. During installation, the sealing airbag is firmly fixed on the inner wall of the filter air duct cavity and is precisely positioned to ensure that they can play a role in the appropriate position. When the gas flows in the filter air duct, the sealing airbag can be elastically deformed according to the change of gas pressure.

[0024] Preferably, the linkage piston column and the filter air duct form a sliding connection, and a spring is connected between the linkage piston column and the filter air duct, one end of the connecting air groove is respectively connected to the cavities of the two sealed air bags, and the outer surface of the positioning connecting plate corresponding to the sealed air bag is provided with a card groove.

[0025] By adopting the above technical solution, a spring is connected between the linkage piston column and the filter air duct. The setting of this spring has multiple important functions. The spring provides elastic support and buffering for the linkage piston column. When external power pushes the linkage piston column to slide in the groove of the filter air duct, the spring will produce corresponding elastic force changes according to the displacement of the piston column. When the external power is withdrawn, the elastic force of the spring will prompt the linkage piston column to automatically reset, ensuring that the system can work repeatedly and stably. When the gas enters the sealed airbag through the connecting air guide groove, the airbag will gradually expand, thereby filling the gap between the filter air duct and the surrounding components, playing a sealing and buffering role.

[0026] Compared with the prior art, the beneficial effects of the present invention are: the high-efficiency and energy-saving air suspension blower:

[0027] 1. An adjusting cylinder and a limiting block are provided. When the device is working, the adjusting cylinder is rotated to drive the limiting block to facilitate unlocking. At this time, the adjusting cylinder will drive the positioning baffle to move, which is convenient for assisting the telescopic airbag to extend and retract. Subsequently, the rotation of the adjusting cylinder will drive the adjusting baffle to rotate through the supporting cylinder, thereby blocking the gas, facilitating the prevention of air flow during cleaning, and increasing the cavity capacity by assisting the telescopic airbag, thereby ensuring the stability of the overall air pressure and improving the practicality of the device;

[0028] 2. A connecting arm and a locking block are provided, so that when the device is working, the positioning baffle plate drives the transmission tooth plate to slide through the movement of the positioning baffle plate, and the tooth block on the surface of the transmission tooth plate will engage the linkage gear, and the rotation of the linkage gear drives the connecting arm to rotate, and the connecting arm presses and installs the positioning connecting plate and the filter screen mounting frame through the locking block at one end, which is conducive to ensuring the stability of the positioning connecting plate and the filter screen mounting frame, reducing the time for disassembly and fixing, and increasing the convenience of use;

[0029] 3. A connecting air guide groove and a sealing air bag are provided. When the device is working, the locking pressure block is installed and pressed so that the locking pressure block pushes the linkage piston column to slide. The linkage piston column pushes the air on one side from the connecting air guide groove into the sealing air bag. The two symmetrical sealing air bags expand and deform after being inflated, so that the sealing air bags are stuck in the slots of the positioning connecting plate, thereby increasing the sealing performance of the positioning connecting plate and the practicality of the device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-11The present invention provides a technical solution: an efficient and energy-saving air suspension blower, comprising a blower body 1, a first connecting pipe 2, a filter air guide pipe 3, a second connecting pipe 4, a first mounting block 5, an adjusting cylinder 6, a limiting block 7, a supporting cylinder 8, an adjusting baffle 9, a positioning baffle 10, a second mounting block 11, a transmission gear plate 12, a linkage gear 13, a connecting arm 14, a locking pressure block 15, a positioning connecting plate 16, a filter screen mounting frame 17, a linkage piston column 18, a connecting air guide groove 19, a sealing air bag 20, an auxiliary telescopic air bag 21, a locking block 22 and an unlocking handle 23. The blower body 1 has a first connecting pipe 2 fixedly installed on the surface of its air inlet, and one end of the first connecting pipe 2 is fixedly provided with two filter air guide pipes 3, and the two filter guide pipes 3 are fixedly provided with the first connecting pipe 2. The other end of the air pipe 3 is fixedly connected to the second connecting pipe 4, the first connecting pipe 2 and the second connecting pipe 4 are of Y-shaped design, one end of the inner wall of the first mounting block 5 is of cylindrical design, and one end of the cylindrical inner wall of the first mounting block 5 is provided with a rectangular groove, and the adjusting cylinder 6 is rotatably connected with the positioning baffle 10. When the device is used, the outside air is guided and transmitted through the first connecting pipe 2, the filter air duct 3 and the second connecting pipe 4, and the air is filtered and cleaned by the filter mounting frame 17 during the flow of air. When the filter mounting frame 17 needs to be cleaned, the adjusting cylinder 6 is rotated so that the adjusting cylinder 6 drives the adjusting baffle 9 to rotate through the supporting cylinder 8, so that the adjusting baffle 9 can be rotated vertically, thereby preventing air from circulating from the filter air duct 3 on this side.

[0044] The outer surface of the filtering air duct 3 is fixedly connected with a first mounting block 5, and an adjusting cylinder 6 is installed through the surface of the first mounting block 5.

When the adjusting cylinder 6 rotates, the adjusting cylinder 6 drives the limiting block 7 to rotate. The card block 7 rotates, and at this time the limit card block 7 is inserted into the rectangular groove of the first mounting block 5, which is convenient for the adjustment cylinder 6 to move out of the first mounting block 5, so that the adjustment cylinder 6 slides relative to the supporting cylinder 8, thereby ensuring the stability of the adjustment baffle 9, and preventing the limit card block 7 from moving after the limiting movement of the locking card block 22. When unlocking is required, the locking card block 22 is driven by pulling the unlocking handle 23 to facilitate moving and unlocking, thereby improving practicality. After the adjustment cylinder 6 moves, it will drive the positioning baffle 10 to move. The movement of the positioning baffle 10 will stretch the auxiliary telescopic airbag 21 to expand it. The auxiliary telescopic airbag 21 increases the capacity of the filter air duct 3 on the closed side, so that when the air flows through the filter air duct 3 on the other side, the pressure will not be too large to cause damage.

When the positioning baffle 10 moves, the positioning baffle 10 drives the transmission tooth plate 12 to slide relative to the second mounting block 11, so that the transmission tooth plate 12 drives the linkage gear 13 and the connecting arm 14 to rotate through the tooth block, and the connecting arm 14 drives the locking pressure block 15 at one end to move, thereby loosening the positioning connecting plate 16. The personnel remove the filter mounting frame 17 by pulling the positioning connecting plate 16, which is convenient for the maintenance and replacement of the filter mounting frame 17.

[0046] The side surface of the first mounting block 5 is provided with an opening, and the inner wall of the opening of the first mounting block 5 is provided with a locking card block 22, one end of the locking card block 22 is fixedly connected with an unlocking handle 23, the linkage fastening mechanism includes a transmission tooth plate 12, the transmission tooth plate 12 is fixedly connected to the outer surface of one end of the positioning baffle 10, the inner wall of the second mounting block 11 is provided with a linkage gear 13, the outer surface of the second mounting block 11 is provided with two connecting rotating arms 14, and one end of the two connecting rotating arms 14 is fixedly connected with a locking pressure block 15, one end of the transmission tooth plate 12 passes through the second mounting block 11, and the transmission tooth plate 12 and the second mounting block 11 form a sliding connection, and the transmission A tooth block is provided on the surface of the tooth plate 12, and the transmission tooth plate 12 is rotatably connected with the linkage gear 13 through the tooth block.

After reinstalling the positioning connecting plate 16 and the filter mounting frame 17, the adjusting cylinder 6 is rotated in the opposite direction and the positioning baffle 10 is pushed to reset, so that the transmission tooth plate 12 drives the linkage gear 13 to connect the rotating arm 14 and the locking pressure block 15 to reverse, so that the locking pressure block 15 can re-press and fix the positioning connecting plate 16 and the filter mounting frame 17. At the same time, the pressing of the locking pressure block 15 will push the linkage piston column 18 to slide.

[0047] The outer surface of the filter air duct 3 is provided with an opening, and the inner wall of the opening of the filter air duct 3 is provided with a positioning connecting plate 16, and one end of the positioning connecting plate 16 is fixedly connected to a filter mounting frame 17, the outer surface of the filter air duct 3 is provided with a groove, and the inner wall of the groove of the filter air duct 3 is installed with a linkage piston column 18, the inner wall of the groove of the filter air duct 3 is provided with a connecting air guide groove 19, and the inner wall of the cavity of the filter air duct 3 is fixedly connected with two sealing air bags 20, the linkage piston column 18 is slidably connected to the filter air duct 3, and a spring is connected between the linkage piston column 18 and the filter air duct 3, and the connection One end of the air-connecting groove 19 is respectively connected with the cavities of the two sealed airbags 20.

[0048] Working principle: When using the energy-efficient air suspension blower, the air is circulated between the first connecting tube 2, the filter air guide tube 3 and the second connecting tube 4 to facilitate the circulation of air between the blower body 1. The adjusting cylinder 6 is rotated to drive the supporting cylinder 8 and the adjusting baffle 9 to control the air volume. The adjusting cylinder 6 drives the limiting card block 7 to rotate to facilitate its extension of the first mounting block 5, so that the locking card block 22 limits the limiting card block 7.
