Description

Technical Field

[0001] This invention belongs to the field of air compressor technology, and particularly relates to an in-line double scroll compressor. Background Technology

[0002] In the application of molecular sieve oxygen generators (especially VPSA vacuum pressure swing adsorption systems), the compressor, as the core power component, directly determines the oxygen production efficiency and stability of the entire machine. Currently, traditional oxygen generators generally use compressors with a single scroll structure, which achieves gas compression through the relative motion of a pair of stationary and moving scrolls. However, with the rapid development of medical and industrial oxygen generation equipment towards lightweight and integrated designs, the limitations of existing single scroll structures are becoming increasingly apparent.

[0003] Traditional single-scroll compressors often exhibit low efficiency when facing the high pressure ratio and large flow rate conditions required by VPSA (Vacuum-Pulse-Saving System) processes, making it difficult to meet the stringent requirements for pressure stability and gas volume sufficiency during the vacuum desorption stage. To achieve the target discharge pressure and flow rate, existing technologies typically rely on increasing the radial dimension of the scroll plate or increasing the number of scroll rotations. This physical enlargement not only results in a bulky compressor with a large footprint and increased weight but also contradicts the current design trend of compact, portable, and lightweight oxygen concentrators. This has become a key bottleneck restricting the performance improvement of oxygen concentrators. Summary of the Invention

[0004] The purpose of this invention is to provide an in-line dual-scroll scroll compressor to solve the problem of large space occupation of conventional single-scroll compressors in the background art.

A receiving groove is opened on the side of the second base facing the first base. A first stationary turbine disk and a second stationary turbine disk are arranged side by side in the receiving groove. The moving turbine assembly includes a moving turbine frame, a first moving turbine disk, and a second moving turbine disk. The moving turbine frame is rotatably disposed between the first base and the second base. The first moving turbine disk and the second moving turbine disk are installed side by side on the side of the moving turbine frame facing the second base. The first moving turbine disk is correspondingly disposed with the first stationary turbine disk, and the second moving turbine disk is correspondingly disposed with the second stationary turbine disk. When the second base is installed on the first base, a receiving cavity is formed between the moving turbine frame and the receiving groove. The first moving turbine disk and the first stationary turbine disk are offset by a preset distance.

[0007] Furthermore, the driving component includes a motor and a drive shaft. The fixed end of the motor is mounted on the first base, and the driving end of the motor is connected to the bottom of the transmission ring. The motor drives the drive shaft to rotate, thereby causing the moving turbine frame to oscillate circumferentially through the cooperation of the linkage plate with the first eccentric wheel and the second eccentric wheel.

[0015] The beneficial effects of the present invention are as follows: Compared with the prior art, the in-line double scroll compressor has the following advantages: 1) Through the cooperation of the first base, the second base, the moving turbine assembly and the drive unit, a dual compression chamber is formed by the pairing and meshing of parallel double stationary turbine disks and double moving turbine disks. The moving turbine disks and stationary turbine disks are offset by the vortex rotation radius. With the cooperation of the central air outlet and the base air inlet structure, dual-path synchronous air compression can be achieved, which greatly improves the compressor's exhaust volume and working efficiency. The independent compression of the dual chambers can reduce the load of a single chamber and make the operation more stable. At the same time, the overall structure is compact, occupies little space, has high space utilization, and the gas flow is smooth and the compression process is stable. 2) The drive structure is composed of a drive component, a linkage plate, and an eccentric wheel assembly containing a first eccentric wheel and a second eccentric wheel. The eccentric wheel adopts an eccentrically set snap ring and a transmission ring, which are installed in conjunction with the corresponding eccentric offset slots on the moving turbine frame. The linkage plate synchronously connects the two eccentric wheels to achieve linkage transmission, which can ensure the synchronicity and consistency of the rotational motion of the dual moving turbine disks, and avoid vibration and wear caused by asynchronous operation of the dual compression chambers. The eccentric structure is precisely matched, has high transmission efficiency, can stably realize the circumferential rotational motion of the moving turbine frame, and has a regular assembly structure and uniform force distribution. 3) A connecting block is added between the drive shaft and the transmission ring. The two ends of the connecting block are connected to the drive shaft and the transmission ring respectively, and the two are eccentrically set. This can further optimize the eccentricity of power transmission, accurately match the vortex rotation radius requirement, improve the accuracy of the rotation of the turbine frame, avoid motion deviation caused by transmission clearance, reduce impact wear of meshing parts, extend the service life of the compressor, and enhance the stability and reliability of the drive structure.

[0018] 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.

[0019] Example 1: Please see Figures 1 to 6As shown, the present invention provides an in-line dual-scroll scroll compressor, comprising a first base 10, a second base 20, a moving turbine assembly 30, and a drive unit 40, wherein: the second base 20 is spaced apart and mounted on the first base 10, and a receiving groove 200 is formed on the side of the second base 20 facing the first base 10, and a first stationary turbine disk 21 and a second stationary turbine disk 22 are arranged side by side in the receiving groove 200; the moving turbine assembly 30 includes a moving turbine frame 300, a first moving turbine disk 31, and a second moving turbine disk 32, and the moving turbine frame 300 is rotatably disposed between the first base 10 and the second base 20. The first moving turbine disk 31 and the second moving turbine disk 32 are mounted side by side on the side of the moving turbine frame 300 facing the second base 20. The first moving turbine disk 31 is correspondingly arranged with the first stationary turbine disk 21, and the second moving turbine disk 32 is correspondingly arranged with the second stationary turbine disk 22. When the second base 20 is mounted on the first base 10, a receiving cavity is formed between the moving turbine frame 300 and the receiving groove 200. The first moving turbine disk 31 and the first stationary turbine disk 21 are offset by a preset distance, and the second moving turbine disk 32 and the second stationary turbine disk 22 are offset by a preset distance. The outer surface of the first moving turbine disk 31 is adjacent to the first stationary turbine disk. The inner surfaces of the second turbine disk 21 mesh with each other to form a first compression chamber 23. The outer surface of the second moving turbine disk 32 meshes with the inner surface of the second stationary turbine disk 22 to form a second compression chamber 24. The offset of the preset distance is the vortex rotation radius. A first air outlet 25 is provided through the center of the first stationary turbine disk 21 on the second base 20. The first compression chamber 23 at the very center is connected to the outside through the first air outlet 25. A second air outlet 26 is provided through the center of the second stationary turbine disk 22 on the second base 20. The second compression chamber 24 at the very center is connected to the outside through the second air outlet 26. At least one air inlet 27 is provided on the cavity 0, and the cavity is connected to the outside through the air inlet 27. The drive end of the drive unit 40 is connected to the moving turbine frame 300. The drive unit 40 is configured to drive the moving turbine frame 300 to rotate, so that the outer side of the first moving turbine disk 31 and the outer side of the second moving turbine disk 32 respectively make a circular rotation between the inner side of the corresponding first stationary turbine disk 21 and the inner side of the second stationary turbine disk 22, thereby causing the air entering through the air inlet 27 to flow out through the first compression chamber 23 and the second compression chamber 24 and then out through the first air outlet 25 and the second air outlet 26 respectively.

[0020] Preferably, there are two air inlets 27. The first air inlet 27 is located at the end of the outermost first stationary turbine disk 21, and the second air inlet 27 is located at the end of the outermost second stationary turbine disk 22.

[0021] Specifically, the air intake 27 can also be set to three, four or five, etc. The number of air intakes 27 can be adjusted according to different application scenarios, which will not be elaborated on here.

[0022] As can be seen, through the cooperation of the first base 10, the second base 20, the moving turbine assembly 30 and the drive unit 40, a dual compression chamber is formed by the pairing and meshing of parallel double stationary turbine disks and double moving turbine disks. The moving turbine disks and stationary turbine disks are arranged with an offset vortex rotation radius. With the structure of the central air outlet and the base air inlet 27, dual-path synchronous air compression can be achieved, which greatly improves the compressor's exhaust volume and working efficiency. The independent compression of the dual chambers can reduce the load of a single chamber and make the operation more stable. At the same time, the overall structure is compact, occupies little space, has a high space utilization rate, and the gas flow is smooth and the compression process is stable.

[0023] In one embodiment, the drive unit 40 includes a drive member 41, a linkage plate 42, and an eccentric wheel assembly 43. The eccentric wheel assembly 43 includes a first eccentric wheel 430 and a second eccentric wheel 431 arranged side-by-side and spaced apart. Both the first eccentric wheel 430 and the second eccentric wheel 431 are rotatably disposed between the first base 10 and the moving turbine frame 300. Each of the first eccentric wheel 430 and the second eccentric wheel 431 includes a retaining ring 430a and a transmission ring 430b, which are eccentrically positioned. The moving turbine frame 300 has a first biasing groove 301 and a second biasing groove 302 on the side facing the first base 10. The first biasing groove 301 is eccentrically positioned with respect to the first moving turbine disk 31. The offset groove 302 is eccentrically set with the second moving turbine disk 32. The snap ring 430a of the first eccentric wheel 430 is installed in the first offset groove 301, and the snap ring 430a of the second eccentric wheel 431 is installed in the second offset groove 302. Both ends of the linkage plate 42 are provided with snap grooves 420 that are adapted to the transmission ring 430b. The snap groove 420 at the first end of the linkage plate 42 is sleeved on the transmission ring 430b of the first eccentric wheel 430, and the snap groove 420 at the second end of the linkage plate 42 is sleeved on the transmission ring 430b of the second eccentric wheel 431. The driving end of the driving component 41 is connected to the bottom of the transmission ring 430b of the first eccentric wheel 430 or the bottom of the transmission ring 430b of the second eccentric wheel 431.

[0024] Specifically, bearings are installed in the first biasing groove 301 and the second biasing groove 302. The retaining ring 430a is installed in the bearing. The retaining ring 430a of the first eccentric wheel 430 is installed in the first biasing groove 301 through the bearing. The retaining ring 430a of the second eccentric wheel 431 is installed in the second biasing groove 302 through the bearing. A bearing is installed in the retaining groove 420. The transmission ring 430b is installed in the bearing. The retaining groove 420 at the first end of the linkage plate 42 is sleeved on the transmission ring 430b of the first eccentric wheel 430 through the bearing. The retaining groove 420 at the second end of the linkage plate 42 is sleeved on the transmission ring 430b of the second eccentric wheel 431 through the bearing.

[0025] Preferably, the driving end of the driving member 41 is connected to the bottom of the transmission ring 430b of the first eccentric wheel 430.

[0026] As can be seen, the drive structure is formed by the drive component 41, the linkage plate 42, and the eccentric wheel group 43 containing the first eccentric wheel 430 and the second eccentric wheel 431. The eccentric wheels are installed with eccentrically set snap rings 430a and transmission rings 430b, which are installed in conjunction with the corresponding eccentric offset slots on the moving turbine frame 300. The linkage plate 42 synchronously connects the two eccentric wheels to achieve linkage transmission, which can ensure the synchronicity and consistency of the rotation of the dual moving turbine disks, avoid vibration and wear caused by asynchronous operation of the dual compression chambers. The eccentric structure is precisely matched, has high transmission efficiency, can stably realize the circumferential rotation of the moving turbine frame 300, and has a regular assembly structure and uniform force distribution.

[0027] In one embodiment, the drive unit 41 includes a motor (not shown) and a drive shaft 410. The fixed end of the motor is mounted on the first base 10, and the drive end of the motor is connected to the bottom of the transmission ring 430b. The motor drives the drive shaft 410 to rotate, so as to drive the turbine frame 300 to oscillate in a circular motion through the cooperation of the linkage plate 42 with the first eccentric wheel 430 and the second eccentric wheel 431.

[0028] Of course, as another implementation, the drive unit 41 can also be a drive module with torque output composed of a cylinder and a transmission assembly.

[0029] As can be seen, by using a motor and drive shaft 410 as the driving component 41, with the motor fixed to the first base 10 and the drive shaft 410 directly connected to the bottom of the transmission ring 430b, the power transmission path is short and direct, which can accurately drive the turbine frame 300 to make circumferential oscillations, and the power output is stable. The motor is firmly installed, which can reduce the shaking during operation. It is suitable for the continuous operation requirements of the double scroll structure, ensuring that the compression work is continuously and stably carried out. At the same time, the overall drive layout is simple, which is convenient for assembly and later maintenance.

[0030] In one embodiment, a connecting block 411 is provided between the drive shaft 410 and the transmission ring 430b. The first end of the connecting block 411 is installed at the end of the drive shaft 410, and the second end of the connecting block 411 is installed at the bottom of the transmission ring 430b. The connecting block 411 and the transmission ring 430b are eccentrically arranged.

[0031] Specifically, the first base 10 has a clearance opening for avoiding the drive shaft 410.

[0032] Specifically, a connecting block 411 is provided between the drive shaft 410 and the transmission ring 430b of the first eccentric wheel 430, and a connecting block 411 is also installed at the bottom of the transmission ring 430b of the first eccentric wheel 430.

[0033] Specifically, the connecting block 411 is a motor connector.

[0034] As can be seen, by adding a connecting block 411 between the drive shaft 410 and the transmission ring 430b, with the two ends of the connecting block 411 connected to the drive shaft 410 and the transmission ring 430b respectively and the two being eccentrically set, the eccentricity of power transmission can be further optimized, the vortex rotation radius requirement can be accurately matched, the accuracy of the 300-degree rotation of the drive turbine frame can be improved, the motion deviation caused by the transmission clearance can be avoided, the impact wear of the meshing parts can be reduced, the service life of the compressor can be extended, and the stability and reliability of the drive structure can be enhanced.

[0035] In one implementation, the second base 20 is detachably mounted on the first base 10 via a disassembly assembly 50. The disassembly assembly 50 includes four first mounting posts 51 and two second mounting posts 52. A first corner mounting hole 54 is provided at each of the four corners of the first base 10, and each first corner mounting hole 54 corresponds to one first mounting post 51. A second corner mounting hole 55 is provided at each of the four corners of the second base 20 corresponding to each first corner mounting hole 54. The first end of each first mounting post 51 is screwed into the first corner mounting hole 54 by a bolt. The second end of the first mounting post 51 is screwed into the second corner mounting hole 55 by bolts. A first side mounting hole 56 is provided on each of the two sides of the first base 10. Each first side mounting hole 56 corresponds to a second mounting post 52. A second side mounting hole 57 is provided on each of the two sides of the second base 20 corresponding to each first side mounting hole 56. The first end of each second mounting post 52 is screwed into the first side mounting hole 56 by bolts, and the second end of each second mounting post 52 is screwed into the second side mounting hole 57 by bolts.

[0036] Specifically, threaded holes are provided at both ends of the first mounting post 51 and the second mounting post 52. The shank of the bolt is tightened into the threaded hole, so that the head of the bolt abuts against the first base 10 and the second base 20.

[0037] As can be seen, the second base 20 and the first base 10 are detachably connected by the assembly 50, which is equipped with four first mounting posts 51 and two second mounting posts 52. The four corner first mounting posts 51 and the side second mounting posts 52 provide multi-point fixation. The bolt connection method makes disassembly and assembly convenient. The multi-directional fixation ensures that the two bases are firmly connected and are not easy to loosen or shift during operation. It takes into account both assembly convenience and structural stability, and facilitates the inspection, replacement and cleaning of the internal components of the compressor.

[0038] In one embodiment, a guide assembly is also provided between the first base 10 and the second base 20. The guide assembly includes two sets of guide units, each set of guide units is provided corresponding to a second mounting post 52, and each set of guide units includes two guide posts 53. The two guide posts 53 are symmetrically arranged on both sides of the corresponding second mounting post 52. A first guide hole 58 is provided on the first base 10, and a second guide hole 59 is provided on the second base 20. The first end of the guide post 53 extends into the first guide hole 58, and the second end of the guide post 53 extends into the second guide hole 59.

[0039] As can be seen, by adding two sets of guide units corresponding to the second mounting column 52 between the two bases, each set contains two symmetrically distributed guide columns 53, which, together with the guide holes on the base, realize assembly guidance, can accurately position the relative position of the first base 10 and the second base 20, avoid misalignment during assembly, ensure the meshing accuracy of the moving turbine disk and the stationary turbine disk, improve the structural strength of the base connection, distribute the force during operation, and further enhance the overall stability of the compressor.

[0040] In one embodiment, the bottom of the moving turbine frame 300 is provided with a plurality of heat dissipation holes 303, which are spaced apart along the width direction of the moving turbine frame 300, and the receiving groove 200 is connected to the outside through the plurality of heat dissipation holes 303.

[0041] As can be seen, by opening multiple spaced heat dissipation holes 303 along the width direction at the bottom of the moving turbine frame 300, the receiving groove 200 is connected to the outside, which can dissipate the heat generated during the compression process in a timely manner, reduce the working temperature of the compression chamber and the moving turbine assembly 30, avoid high temperature affecting the performance and service life of the components, and at the same time, the heat dissipation holes 303 are reasonably arranged, do not affect the structural strength of the moving turbine frame 300, and improve the reliability of the compressor in long-term operation.

[0042] As one implementation method, the bottom of the dynamic turbine frame 300 is provided with multiple weight reduction holes.

[0043] As can be seen, by opening multiple weight-reducing holes at the bottom of the moving turbine frame 300, the overall weight of the moving turbine frame 300 can be effectively reduced, the drive load of the drive unit 40 can be reduced, the energy consumption of the motor can be reduced, the inertial force during the rotation of the moving turbine frame 300 can be reduced, vibration and noise can be reduced, and the smoothness of compressor operation can be improved. Moreover, the weight-reducing holes will not damage the core structural strength of the moving turbine frame 300, thus balancing lightweight and structural stability.

[0044] In one embodiment, the bottom of the moving turbine frame 300 is provided with a plurality of weight reduction grooves 304, the plurality of weight reduction grooves 304 are spaced apart along the width direction of the moving turbine frame 300 and each weight reduction groove 304 extends along the length direction of the moving turbine frame 300.

[0045] As can be seen, multiple weight-reducing grooves 304 extending along the length direction and spaced apart in the width direction are opened at the bottom of the moving turbine frame 300 to further optimize the lightweight effect of the moving turbine frame 300, significantly reduce its own weight and motion inertia, reduce drive energy consumption and operating vibration. The extended structure of the weight-reducing grooves 304 can evenly distribute stress, improve the structural rigidity of the moving turbine frame 300, avoid deformation caused by weight reduction, and at the same time help improve the heat dissipation effect.

[0046] In one embodiment, both the first static turbine disk 21 and the second static turbine disk 22 are integrally formed with the second base 20.

[0047] As can be seen, by designing the first stationary turbine disk 21, the second stationary turbine disk 22 and the second base 20 as an integrally formed structure, the assembly process of the stationary turbine disk and the base is eliminated, the production assembly efficiency is improved, gas leakage and meshing deviation caused by assembly gaps are avoided, the positional accuracy and structural strength of the stationary turbine disk are guaranteed, the integrally formed structure has better sealing performance, which can improve compression efficiency, while enhancing the overall rigidity of the second base 20 and extending the service life of the compressor.

[0048] Example 2: The difference between this embodiment and Embodiment 1 is that the disassembly / assembly component 50 only includes four first mounting posts 51. Please refer to [link / reference]. Figures 7 to 9 As shown, in another embodiment, an eccentric connection part 60 is provided between the first base 10 and the linkage plate 42. The eccentric connection part 60 includes two eccentric connection shafts 61, which are symmetrically arranged. Each eccentric connection shaft 61 includes an eccentrically arranged upper eccentric shaft and a lower eccentric shaft. The first base 10 has two first connection holes 11, each corresponding to one eccentric connection shaft 61. The linkage plate 42 has two second connection holes 421, each corresponding to one first connection hole 11. Bearings are installed in each first connection hole 11 and each second connection hole 421. The upper and lower eccentric shafts of the eccentric connection shafts 61 are both connected to bearings. The lower eccentric shaft of the eccentric connection shaft 61 is installed in the first connection hole 11 through a bearing, and the upper eccentric shaft of the eccentric connection shaft 61 is installed in the second connection hole 421 through a bearing.

[0049] When the inline dual-scroll scroll compressor of this application is working: the motor outputs rotational power, which drives the first eccentric wheel 430 to rotate via the drive shaft 410. During the rotation of the first eccentric wheel 430, the retaining ring 430a rotates within the first offset groove 301. Simultaneously, the retaining ring 430a of the first eccentric wheel 430 drives the second eccentric wheel 431 to rotate synchronously via the linkage plate 42. The two work together to drive the moving turbine frame 300 to perform a set circumferential rotation between the first base 10 and the second base 20. The first moving turbine disk 31 and the second moving turbine disk 32, which are arranged side by side on the moving turbine frame 300, rotate synchronously, respectively interacting with the first stationary turbine disk 21 and the second stationary turbine disk 22 within the receiving groove 200 of the second base 20. The meshing mechanism generates periodic volume changes within the first compression chamber 23 and the second compression chamber 24 formed by the offset fit. Outside air enters the accommodating chamber formed by the moving turbine frame 300 and the accommodating groove 200 through the air inlet 27 on the second base 20, and is then drawn into the two independent compression chambers. As the chamber volume continuously decreases, air compression is completed. The compressed high-pressure gas is discharged to the outside from the first air outlet 25 at the center of the first stationary turbine disk 21 and the second air outlet 26 at the center of the second stationary turbine disk 22, respectively, achieving continuous, dual-path synchronous compression air supply. During operation, the heat dissipation holes 303 on the moving turbine frame 300 can dissipate the heat generated by compression in a timely manner. Combined with the lightweight structural design, this enables the compressor to operate continuously, stably, efficiently, and with low energy consumption.
