Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure blowers, and in particular to a vortex-type high-pressure blower. Background Art

[0002] As the core component of efficient gas delivery equipment, the vortex high-pressure blower can generate a significant pressure gradient in a compact space through the synergistic effect of its unique impeller structure and gas compression chamber. It is now widely used in key areas such as industrial vacuum adsorption, pneumatic conveying and environmental control. This technology relies on the characteristic of single-stage compression to achieve high-pressure output. It has demonstrated irreplaceable advantages in scenarios such as semiconductor manufacturing and food packaging automation with strict cleanliness requirements, and has become a basic unit of modern industrial gas source systems.

[0003] In current application practices, fixed filters are generally installed at the air inlet of vortex fans to intercept solid impurities in the inhaled air flow. However, when high-hardness particles, such as metal debris and gravel, invade the pores of the filter, they are very likely to form rigid physical blockages, which are difficult to effectively remove by conventional backflushing or vibration cleaning methods. Continuous blockage will directly lead to a sharp decrease in the air inlet cross-sectional area, affecting the operation of the fan. Although existing technologies have attempted to optimize the filter material or increase the frequency of cleaning, there is still a lack of effective solutions for the removal of hard foreign matter, which in turn induces chain operation failures such as a decrease in the fan's suction efficiency and an abnormal increase in energy consumption.

[0004] Therefore, it is necessary to provide a new vortex high-pressure blower to solve the above technical problems. Summary of the Invention

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this disclosure, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0018] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0019] See also Figures 1 to 6 As shown, an embodiment of the present invention provides a vortex high-pressure blower, including a blower body 1, the blower body 1 includes a mounting frame 101 and a casing 102 fixedly connected to the mounting frame 101, an air inlet pipe 103 for air intake and an air outlet pipe 104 for exhaust are provided on the casing 102, a gas compression chamber is provided in the casing 102, an impeller is provided in the gas compression chamber, a motor 105 for driving the impeller to rotate is fixedly connected to the mounting frame 101, the ends of the air inlet pipe 103 and the air outlet pipe 104 are detachably connected with an air inlet 107 and an air outlet 108 respectively, an end of the air inlet 107 close to the air inlet pipe 103 is fixedly connected to a filter component 2 and a connecting component 3, and an electric push rod 106 for controlling the filter component 2 is fixedly connected to the air inlet pipe 103; the filter component 2 includes a movable frame 21 slidably arranged in the air inlet 107 and a fixed connecting The baffle 26 is connected to the air inlet 107, and a filter 211 is fixedly connected to the movable frame 21. The baffle 26 is provided with a plurality of air ducts 27 for air to pass through and a plurality of plug rods 28 adapted to the filter 211. The filter component 2 is used to filter the gas sucked into the air inlet pipe 103; the connecting component 3 is used to connect the electric push rod 106 to the movable frame 21 to control the movement of the filter component 2. This arrangement, through the design of the detachable air inlet 107 and the air outlet 108, facilitates the rapid replacement or maintenance of the filter component 2. In addition, the plug rod 28 of the baffle 26 cooperates with the filter 211 to form a self-cleaning structure, which automatically clears blockages when the filter 211 moves. The linkage design of the electric push rod 106 and the connecting component 3 realizes the switching control between the filtering state and the cleaning state. The filter 211 can be cleaned without stopping the machine, which significantly improves the continuous operation efficiency of the fan.

[0020] Among them, the filter screen 211 is provided with a plurality of filter holes 212 arranged in an array. The filter holes 212 are arranged in a square shape, and the cross-section of the insertion rod 28 is arranged in a square shape. The size of the insertion rod 28 is slightly smaller than the size of the filter hole 212, so that when the filter screen 211 moves to the insertion rod 28, the insertion rod 28 can push out the debris in the filter screen 211. In this way, the square filter holes 212 are matched with the size of the insertion rod 28 to ensure that the insertion rod 28 can be forced to pass through the filter hole 212 and push out the stuck particles, while avoiding scraping failure caused by too large a gap or friction damage caused by too small a gap. This design upgrades traditional passive filtration to active mechanical slag cleaning, solves the problem of reduced air intake efficiency caused by blockage of the filter screen 211, and extends the service life of the filter screen 211.

[0021] It should be noted that, in specific implementation, the filter screen 211 can be made of high-strength stainless steel, and a precision stamping process is used to ensure that all filter holes 212 maintain strictly uniform square geometric specifications. At the same time, the overall thickness of the filter screen 211 is set to match the length of the insertion rod 28. This setting, on the one hand, can enable the filter screen 211 to maintain sufficient structural strength, and on the other hand, through the clearance between the hole and the insertion rod 28, ensure that the insertion rod 28 can accurately penetrate the hole to eject the embedded particles.

[0022] Furthermore, the top of the movable frame 21 is fixedly connected to a first slider 22 with a "cross" cross-section, and the bottom of the movable frame 21 is fixedly connected to a second slider 23 with an inverted "T" cross-section. The air inlet 107 is provided with a first slide groove 24 and a second slide groove 25 respectively adapted to the first slider 22 and the second slider 23. In this way, through the limitation of the "cross" and inverted "T" shaped sliders, the precise horizontal guidance of the movable frame 21 is ensured, and the filter screen 211 is prevented from vibrating and falling off under the impact of airflow. The symmetrical layout of the double sliders improves the stability and reliability of the movement of the filter component 2.

[0023] Secondly, the first slider 22 is set to pass through the top of the air inlet 107, and the top of the first slider 22 is fixedly connected to the connecting plate 31. The protruding end of the electric push rod 106 is fixedly connected to the mounting block 32. The mounting block 32 is used to connect with the connecting plate 31 to drive the movement of the filter 211 through the electric push rod 106. This arrangement allows the connecting plate 31 to be exposed to the outside of the air inlet 107, which is convenient for quick disassembly and maintenance. The modular docking structure of the mounting block 32 and the connecting plate 31 separates the power transmission from the filter component 2. When the filter 211 needs to be replaced, it is only necessary to release the connection between the mounting block 32 and the connecting plate 31 to pull out the movable frame 21, which greatly reduces the maintenance complexity and downtime.

[0024] The second limit block 34 is fixedly connected to the mounting block 32, and the second limit block 34 is slidably connected to the mounting block 32. The two second limit blocks 34 are elastically connected, and a limit hole 37 is formed on the connecting plate 31 that is adapted to the size of the mounting block 32. The spacing between the first limit block 33 and the second limit block 34 is the same as the depth of the limit hole 37, so that when the mounting block 32 is located in the limit hole 37, the first limit block 33 and the second limit block 34 can limit each other between the connecting plate 31 and the mounting block 32. This arrangement allows the first limit block 33 to act as a rigid stop to resist tension, and the elastically retractable second limit block 34 to further resist vibration loosening by locking, ensuring that the connecting plate 31 can move with the mounting block 32 in two directions. The precise matching of the depth of the limit hole 37 and the limit block spacing enables the mounting block 32 to be quickly assembled with the connecting plate 31, avoiding the tool operation required for threaded connection, and realizing one-click disassembly and assembly.

[0025] Specifically, the two second limit blocks 34 are elastically connected by a spring 38, and the side surfaces of the two second limit blocks 34 are both inclined, so that the limit blocks can move under pressure when they contact the wall of the limit hole 37. The inclined surface design allows the second limit block 34 to automatically retract when inserted into the limit hole 37, and needs to be manually pressed to unlock when disengaged, forming an anti-accidental touch one-way locking structure, and the pre-tightening force of the spring 38 provides a stable locking holding force, which can still maintain a reliable connection in the high-frequency vibration environment of the fan, avoiding the risk of loosening of traditional bolts due to vibration.

[0026] In addition, a third slider 35 is fixedly connected to the second limit block 34, and a third slide groove 36 that is adapted to the size of the third slider 35 is provided on the mounting block 32. The movement trajectory of the second limit block 34 is limited by the cooperation between the third slider 35 and the third slide groove 36 to prevent it from getting stuck due to deflection or rotation, thereby ensuring its linear movement.

[0027] In addition, mounting holes 29 are provided on the air inlet 107 and the air outlet 108. The mounting holes 29 are used to connect the air inlet 107 and the air outlet 108 to the air inlet pipe 103 and the air outlet pipe 104 respectively by screws. This arrangement allows you to further maintain the detachable advantage of the air inlet 107 and the air outlet 108 to meet frequent maintenance needs.

[0028] Working principle: When the vortex high-pressure blower is working, when the motor 105 drives the impeller to rotate at high speed in the gas compression chamber, the outside air is continuously sucked into the system from the air inlet pipe 103, and the air flow is first filtered through the filter component 2 at the air inlet 107 to intercept solid particles in the air, ensuring that the clean gas passes through the baffle 26 and the air duct 27 to enter the compression chamber. As the filtering time accumulates, when the holes in the filter screen 211 are clogged with impurities and the air intake resistance increases, the electric push rod 106 drives the movable frame 21 to move horizontally through the connecting component 3, and the insertion rod 28 penetrates the hole by virtue of the gap with the filter hole 212, thereby pushing out the embedded particles.

[0029] Compared with related technologies, the vortex high-pressure blower provided by the present invention has the following beneficial effects: 1. The vortex high-pressure blower proposed in the present invention realizes a self-cleaning function through the dynamic cooperation between the filter component 2 and the cleaning mechanism of the plug rod 28. Specifically, the electric push rod 106 drives the movable frame 21 to move laterally, forcing the baffle 26 and the plug rod 28 to accurately penetrate the holes of the filter screen 211, ejecting the embedded debris, breaking through the technical barrier that traditional blowers must be shut down and disassembled for filter maintenance, and solving the problem of continuous operation requirements under high dust conditions and the inconvenience of cleaning the filter screen 211 due to hard debris.

[0030] 2. The vortex high-pressure blower proposed in the present invention adopts a composite structure of rigid limiting and elastic locking to ensure the absolute reliability of the maintenance of core components. Specifically, the first limiting block 33 resists axial tension and forms a bidirectional constraint with the second elastic limiting block. Compared with the traditional threaded fastening mode, it greatly improves the replacement efficiency of the filter 211 while reducing the risk of vibration loosening.

[0031] 3. The vortex high-pressure blower proposed in the present invention achieves a breakthrough in maintenance convenience through the design of the slider track. Specifically, the nested guide of the "cross" and inverted T-shaped slide rails ensures the stability of the movable frame 21 during directional translation, and can also greatly reduce the time spent on routine maintenance.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
