[0062] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0063] This disclosure provides a compressor 100, including at least one set of compression components, which may include: a housing 11, a piston 12, a rotary table 13, a sliding component 14, and a limiting component.

[0064] Specifically, in this disclosure, the housing 11 is hollow to form a receiving space, and the piston 12 is disposed within the receiving space. The outer surface of the piston 12 is in contact with the inner surface of the housing 11 to seal the receiving space. The volume of the piston 12 is smaller than the volume of the receiving space, and the piston 12 is movable along the longitudinal direction Y of the housing 11.

[0065] like Figures 1 to 5 As shown, the turntable 13 is located outside the receiving space and is capable of rotating about the horizontal direction X. The turntable 13 is provided with a groove 133 extending along the longitudinal direction Y, and the distance between any two points of the groove 133 and the rotation center of the turntable 13 is different.

[0066] Among them, such as Figures 4 to 5 As shown, the two opposite surfaces of the turntable 13 in the horizontal X direction are defined as the first surface 131 and the second surface 132, respectively. The groove of the slide 133 can be flush with the first surface 131, that is, the slide 133 penetrates the first surface 131 so that the slide 133 is connected to the external space.

[0067] like Figures 2 to 3 As shown, at least a portion of the sliding component 14 is embedded in the groove 133, the sliding component 14 is connected to the piston 12, and the sliding component 14 is capable of sliding along the extension direction of the groove 133.

[0068] At least a portion of the limiting component is disposed within the slide groove 133 to connect with the sliding component 14. The limiting component and the sliding component 14 are movably connected, and when the sliding component 14 moves to a preset position, the limiting component can restrict the sliding component 14 from sliding along the extension direction of the slide groove 133.

[0069] It should be noted that the longitudinal direction Y in the above refers to the length direction of the housing 11, and the transverse direction X refers to the width direction of the housing 11.

[0070] During the movement of piston 12 along the longitudinal direction Y, a portion of piston 12 can be placed inside the receiving space to seal the receiving space, while another portion of piston 12 can be placed outside the receiving space for connection with sliding assembly 14.

[0071] In some embodiments, the area corresponding to the moving position of the piston 12 can be cylindrical. During the rotation of the turntable 13 around the transverse X, the piston 12 can move along the longitudinal Y and rotate around the longitudinal Y under the drive of the sliding component 14.

[0072] For example, in some embodiments, the turntable 13 may be a disk, and the center of the disk may be the rotation center of the turntable 13. In this case, the groove 133 may extend radially along the turntable 13, and the length of the groove 133 may be less than the radius of the turntable 13, so that the distance between any two points of the groove 133 and the rotation center of the turntable 13 is different.

[0073] However, it is not limited to this, the turntable 13 in the embodiments of this disclosure may also be a structure other than a disc. In addition, when the turntable 13 is a disc, the groove 133 also extends in a direction other than the radial direction of the turntable 13, so that the distance between any two points of the groove 133 and the rotation center of the turntable 13 is different.

[0074] In some embodiments, an elastic membrane may be provided within the containment space, dividing the containment space into a gas chamber and a drive chamber arranged longitudinally along the Y direction. The gas chamber is located on the side of the drive chamber away from the turntable 13, and is used to contain and compress gas. The piston 12 moves within the drive chamber to cause the elastic membrane to vibrate at a certain frequency, thereby adjusting the pressure within the containment space.

[0075] In this embodiment, when the piston 12 moves away from the gas chamber, the volume of the drive chamber increases and the air pressure decreases. The elastic membrane is drawn towards one side of the drive chamber, that is, the elastic membrane bulges away from the gas chamber. The volume of the gas chamber increases and the air pressure decreases, the vibration frequency of the elastic membrane decreases, and gas can be drawn into the gas chamber. When the piston 12 moves towards the gas chamber, the volume of the drive chamber decreases and the air pressure increases. The elastic membrane is pushed towards one side of the drive chamber, that is, the elastic membrane bulges towards the gas chamber. The volume of the gas chamber decreases and the air pressure increases, the vibration frequency of the elastic membrane increases, and the gas is compressed in the gas chamber until the exhaust valve on the housing 11 opens, allowing the gas to be discharged outside the gas chamber through the exhaust valve.

[0076] This embodiment of the present disclosure provides a groove 133 on the turntable 13, with different distances between any two points of the groove 133 and the rotation center of the turntable 13. This allows the sliding component 14 to slide along the extension direction of the groove 133, thereby adjusting the distance between the sliding component 14 and the rotation center of the turntable 13. With a fixed rotation amplitude of the turntable 13, this disclosure adjusts the distance between the sliding component 14 and the rotation center of the turntable 13, thereby adjusting the movement frequency of the sliding component 14 and the piston 12 connected to it in the longitudinal Y direction. This, in turn, adjusts the pressure within the accommodating space to ensure that the pressure within the accommodating space meets the pressure requirements of the gas it contains.

[0077] Specifically, when the rotation amplitude of turntable 13 is constant: if the distance between the sliding component 14 and the rotation center of turntable 13 decreases, the moving frequency of sliding component 14 and piston 12 decreases, and the pressure in the accommodating space also decreases accordingly; if the distance between the sliding component 14 and the rotation center of turntable 13 increases, the moving frequency of sliding component 14 and piston 12 increases, and the pressure in the accommodating space also increases accordingly.

[0078] The compression assembly in this embodiment can compress gas according to different pressure requirements, thereby enhancing the practicality of the compressor 100 and expanding the market for the compressor 100.

[0079] like Figures 3 to 5 As shown, in some embodiments, a receiving groove 134 may also be provided on the turntable 13. The receiving groove 134 extends along the longitudinal direction Y and communicates with the sliding groove 133. The receiving groove 134 and the sliding groove 133 together form a sliding space.

[0080] It should be noted that the two ends of the slide groove 133 in the longitudinal Y direction can be spaced apart from the side circumferential surface of the turntable 13. The receiving groove 134 in the longitudinal Y direction has one end connected to the slide groove 133 and the other end penetrating through the side circumferential surface of the turntable 13, so that the sliding space is connected to the external space.

[0081] The side circumferential surface of the turntable 13 is arranged around the first surface 131 and the second surface 132, and the side circumferential surface of the turntable 13 is located between the first surface 131 and the second surface 132, and is connected to the first surface 131 and the second surface 132.

[0082] In this embodiment, the turntable 13 can be welded together from two rotating plates. Spaces for accommodating the sliding component 14 and the screw 151 can be respectively provided on the two rotating plates, thereby forming a sliding space when the two rotating plates are welded together. However, this is not a limitation; the turntable 13 can also form a sliding space for accommodating the sliding component 14 and the screw 151 by drilling holes in one of the rotating plates.

[0083] In some embodiments, the limiting component may include a screw 151, which is at least partially disposed within the sliding space. A through threaded hole may be formed on the sliding component 14, the axis of which extends longitudinally along the Y direction. The thread on the screw 151 is adapted to the threaded hole, allowing the screw 151 to pass through the threaded hole and achieve a threaded connection with the sliding component 14.

[0084] This embodiment of the invention provides a screw 151 in the limiting assembly, and the screw 151 is threadedly connected to the sliding assembly 14. This allows the position of the sliding assembly 14 on the slide groove 133 to be adjusted by rotating the screw 151 about the longitudinal direction Y. With the turntable 13 rotating by the same amplitude, this embodiment of the invention adjusts the position of the sliding assembly 14 on the slide groove 133, thereby adjusting the movement frequency of the sliding assembly 14 and the piston 12 along the longitudinal direction Y, and consequently adjusting the pressure within the accommodating space.

[0085] Meanwhile, in this embodiment, when the sliding component 14 moves to the preset position, the limiting component can restrict the sliding component 14 from sliding along the extension direction of the slide groove 133, so that when the turntable 13 rotates, the sliding component 14 can be fixed at the preset position, thereby enabling the piston 12 to move at a fixed frequency and ensuring that the pressure in the accommodating space meets the pressure required by the gas it contains.

[0086] It should be noted that the preset position mentioned above refers to the position of the sliding component 14 on the slide groove 133 when the turntable 13 rotates. This disclosure can preset the position of the sliding component 14 on the slide groove 133 according to the required pressure of the gas in the containment space. Thus, when the turntable 13 rotates, the sliding component 14 can be fixed in the preset position, and the piston 12 moves longitudinally along the Y direction at a fixed frequency under the drive of the sliding component 14, so that the pressure in the containment space can meet the pressure required by the gas contained within it under the compression of the piston 12.

[0087] In some embodiments, the longitudinal Y dimension of the screw 151 may not be less than the longitudinal Y dimension of the sliding space, so that when the screw 151 is embedded in the sliding space and abuts against the side wall of the slide groove 133 in the longitudinal Y direction, a portion of the screw 151 may be placed outside the sliding space, so that the operator can connect and disconnect the screw 151 from the turntable 13 and the sliding assembly 14 through the portion of the screw 151 located outside the sliding space.

[0088] In some embodiments, the thread on the screw 151 is located at least at the front end of the screw 151, and the longitudinal Y length of the thread is not less than the longitudinal Y length of the groove 133, so that the sliding assembly 14 can move arbitrarily within the entire length range of the groove 133.

[0089] For example, the thread length on the screw 151 can be equal to the length of the sliding space so that the screw 151 can be adapted to the groove 133 with different longitudinal Y lengths.

[0090] like Figures 2 to 4 As shown, in some embodiments, the limiting component may further include a knob 152 located outside the receiving groove 134 and connected to the rear end of the screw 151.

[0091] It should be noted that the screw 151 includes a front end and a rear end, which are located at opposite ends of the screw 151 in the longitudinal Y direction. When the screw 151 is installed in the sliding space, the front end of the screw 151 can correspond to the slide groove 133, wherein the front end of the screw 151 can abut against the side wall of the slide groove 133 in the longitudinal Y direction, and the rear end of the screw 151 can be located outside the sliding space.

[0092] In this embodiment, the cross-sectional area of ​​the knob 152 is larger than that of the screw 151, which makes it easier for the operator to rotate the screw 151 by rotating the knob 152, thereby realizing the connection and separation between the screw 151 and the sliding assembly 14.

[0093] For example, the knob 152 in this embodiment of the present disclosure may be a hexagonal prism, so that the operator can rotate the screw 151 using tools such as a wrench.

[0094] The knob 152 and the screw 151 can be formed as one piece, or the knob 152 and the screw 151 can be made separately and then fixedly connected.

[0095] like Figures 3 to 4 As shown, in some embodiments, the limiting component may further include a limiting rod that can extend laterally X and penetrate one side wall of the receiving groove 134.

[0096] During the adjustment of the position of screw 151 and / or sliding assembly 14, the limiting member can be moved away from the sliding space to avoid obstructing the movement of screw 151. After the position adjustment of screw 151 and / or sliding assembly 14 is completed, the limiting rod can be inserted into the sliding space and made to abut against screw 151 to restrict the movement of screw 151 within the sliding space.

[0097] For example, the limiting rod in this embodiment may be an internal hex screw, but it is not limited to this. Other structures that can realize the detachable connection between the limiting rod and the turntable 13, besides internal hex screws, may be included in this embodiment.

[0098] In some embodiments, the limiting rod may include a first limiting rod 153. The outer peripheral surface of the screw 151 may be provided with an annular notch 155, and the longitudinal Y dimension of the annular notch 155 may be adapted to the longitudinal Y dimension of the first limiting rod 153.

[0099] When the screw 151 is installed on the turntable 13, for example, when the screw 151 is embedded in the sliding space and abuts against the side wall of the slide groove 133 in the longitudinal Y direction, the first limiting rod 153 is opposite to the annular notch 155. At this time, the first limiting rod 153 can be partially embedded in the sliding space and placed in the annular notch 155, thereby restricting the screw 151 from moving in the longitudinal Y direction in the sliding space.

[0100] It should be noted that the longitudinal Y length of the annular notch 155 can be slightly greater than the longitudinal Y length of the limiting rod. This allows the screw 151 to rotate around the longitudinal Y while the limiting rod restricts the longitudinal Y movement of the screw 151, so as to adjust the position of the sliding component 14 on the screw 151 until the sliding component 14 moves to the preset position.

[0101] In some embodiments, the limiting rod may include a second limiting rod 154. After the position adjustment of the screw 151 and the sliding assembly 14 is completed, the limiting rod may also be embedded in the sliding space and directly abut against the outer peripheral surface of the screw 151 to restrict the screw 151 from rotating about the longitudinal direction Y.

[0102] Of course, in some embodiments, the limiting component may also include both a first limiting rod 153 and a second limiting rod 154. After the screw 151 is mounted on the turntable 13, and before the sliding component 14 moves to the preset position, the first limiting rod 153 can be partially embedded in the annular notch 155 to restrict the screw 151 from moving longitudinally Y within the sliding space. Then, by rotating the screw 151 about longitudinally Y, the position of the sliding component 14 on the screw 151 is adjusted until the sliding component 14 moves to the preset position. After the sliding component 14 moves to the preset position, the second limiting rod 154 is partially embedded in the sliding space, and the second limiting rod 154 abuts against the outer circumferential surface of the screw 151 to restrict the screw 151 from rotating about longitudinally Y.

[0103] In some embodiments, the piston 12 can remain within the receiving space as it moves along the longitudinal Y direction. In this case, a connecting element can be provided between the piston 12 and the sliding assembly 14 to achieve the connection between the piston 12 and the sliding assembly 14.

[0104] Specifically, a connecting rod 121 can be provided at the end of the piston 12 near the tail of the turntable 13. The connecting rod 121 can extend along the longitudinal direction Y. One end of the connecting rod 121 in the longitudinal direction Y can be fixedly connected to the piston 12, and the other end can be movably connected to the sliding assembly 14, so that the piston 12 can move along the longitudinal direction Y under the drive of the sliding assembly 14.

[0105] In some embodiments, the sliding assembly 14 may include a slider 141 and a connecting shaft 142. The slider 141 may be disposed within a groove 133, and a through threaded hole may be formed on the slider 141. The threaded hole is identical to that of the groove 133, and the threaded hole on the slider 141 is adapted to the screw 151. The connecting shaft 142 is connected to the outer side of the slider 141 near the connecting rod 121. The connecting shaft 142 extends laterally along the X direction and protrudes from the groove 133 to be movably connected to the connecting rod 121.

[0106] In this embodiment, a through hole can be formed in the connecting rod 121, extending laterally along the X direction and penetrating through the connecting rod 121. The connecting shaft 142 can pass through the through hole and be movably connected to the connecting rod 121.

[0107] In some embodiments, the top and bottom surfaces of the slider 141 can fit against the top and bottom walls of the groove 133 to improve the stability of the slider 141 sliding within the groove 133.

[0108] It should be noted that the top and bottom surfaces of slider 141 refer to the two opposite sides of slider 141 in the vertical Z direction.

[0109] like Figure 6As shown, in some embodiments, the compressor 100 may include two sets of compression assemblies, which are spaced apart, and the housings 11 in both sets of compression assemblies extend along the longitudinal direction Y. The turntables 13 in the two sets of compression assemblies are located on the opposite inner sides of the two housings 11, that is, the two turntables 13 are located between the two housings 11.

[0110] It should be noted that compressor 100 is typically used for the co-production of different gases. For example, compressor 100 can be used for the co-production of natural gas and hydrogen. In the co-production of different gases, different gases require different pressures when compressed and discharged, and because the discharge pressure of compressor 100 is not easily adjustable, the co-production of different gases is quite challenging.

[0111] To solve the above-mentioned technical problems, this disclosure may also provide a rotating component in the compressor 100 having two sets of compression components. The rotating component may include: a first gear 161, a second gear 162, a first rotating shaft 163, a second rotating shaft 164, a third rotating shaft 165, a fourth rotating shaft 166, and two synchronous belts 167.

[0112] Specifically, such as Figures 6 to 7 As shown, in this embodiment of the present disclosure, the first gear 161 and the second gear 162 mesh with each other. The first gear 161 and the second gear 162 correspond one-to-one with the turntables 13 in the two sets of compression assemblies, and the rotation surfaces of the first gear 161 and the second gear 162 are parallel to the rotation surfaces of the turntables 13.

[0113] It should be noted that the rotating surface mentioned above refers to the surface of a rotating structure that can rotate around its center of rotation.

[0114] The first rotating shaft 163 passes through the first gear 161 and is fixedly connected to the first gear 161. The first rotating shaft 163 and the first gear 161 are coaxially arranged.

[0115] The second rotating shaft 164 passes through the second gear 162 and is fixedly connected to the second gear 162. The second rotating shaft 164 and the second gear 162 are coaxially arranged.

[0116] The third rotating shaft 165 is located between the first gear 161 and the corresponding turntable 13. The third rotating shaft 165 and the corresponding turntable 13 are coaxially arranged and fixedly connected. The lateral X-length of the third rotating shaft 165 is greater than the distance between the corresponding turntable 13 and the first rotating shaft 163.

[0117] The fourth rotating shaft 166 is located between the second gear 162 and the corresponding turntable 13. The fourth rotating shaft 166 and the corresponding turntable 13 are coaxially arranged and fixedly connected. The lateral X-length of the fourth rotating shaft 166 is greater than the distance between the corresponding turntable 13 and the second rotating shaft 164.

[0118] One of the two synchronous belts 167 is fitted onto the end of the first rotating shaft 163 and the end of the third rotating shaft 165 to make the first rotating shaft 163 and the third rotating shaft 165 rotate synchronously. The other synchronous belt 167 is fitted onto the end of the second rotating shaft 164 and the end of the fourth rotating shaft 166 to make the second rotating shaft 164 and the fourth rotating shaft 166 rotate synchronously.

[0119] It should be noted that the end of the first rotating shaft 163 refers to the end of the first rotating shaft 163 near the corresponding turntable 13. The end of the second rotating shaft 164 refers to the end of the second rotating shaft 164 near the corresponding turntable 13. The end of the third rotating shaft 165 refers to the end of the third rotating shaft 165 near the first gear 161. The end of the fourth rotating shaft 166 refers to the end of the fourth rotating shaft 166 near the second gear 162.

[0120] In this embodiment, the number of teeth of the first gear 161 and the second gear 162 satisfy a preset condition. Under this preset condition, the two turntables 13 can rotate under the drive of the rotating assembly, generating a speed difference. That is, the two turntables 13 rotate at different speeds under the drive of the rotating assembly, so that the pressure in the containment space of the two sets of compression assemblies meets the pressure required by the gas contained therein, thereby realizing the co-production of different gases.

[0121] In some embodiments, the rotating assembly may include four synchronous pulleys 168, which may be respectively mounted on a first rotating shaft 163, a second rotating shaft 164, a third rotating shaft 165, and a fourth rotating shaft 166. Each synchronous pulley 168 includes an annular groove located on the side of the synchronous pulley 168 opposite to the central axis of the corresponding rotating shaft. A synchronous belt 167 is disposed within the annular groove.

[0122] In this embodiment, the depth of the annular groove can be greater than the thickness of the synchronization belt 167, so that the synchronization belt 167 can be completely embedded in the annular groove. However, it is not limited to this; the depth of the annular groove can also be less than or equal to the thickness of the synchronization belt 167.

[0123] In this embodiment of the present disclosure, by setting a synchronous pulley 168, the synchronous belt 167 can be confined within the annular groove, which increases the contact surface between the synchronous belt 167 and the corresponding rotating shaft, reduces the risk of the synchronous belt 167 falling off the corresponding rotating shaft, thereby ensuring that the turntable 13 can rotate under the drive of the corresponding gear, and thus ensuring the normal operation of the compressor 100.

[0124] In some embodiments, the ratio of the number of teeth of the first gear 161 to the number of teeth of the second gear 162 may be 1:2. However, it is not limited to this, and the ratio of the number of teeth of the first gear 161 to the number of teeth of the second gear 162 may also be other values, so that the moving frequency of the two pistons 12 in the compressor 100 meets the pressure requirements of the gas in the corresponding containment space.

[0125] like Figures 8 to 11 As shown, in some embodiments, the compressor 100 may include a housing 17, in which a vertical plate is provided. The vertical plate extends along the longitudinal direction Y, and the side periphery of the vertical plate is fitted with the inner side wall of the housing 17 to realize the connection between the vertical plate and the housing 17.

[0126] The rotating assembly and turntable 13 are disposed inside the housing 17 and mounted on the upright plate.

[0127] Specifically, in this embodiment, the first rotating shaft 163 and the second rotating shaft 164 can be rotatably connected to the side of the upright plate away from the turntable 13, the third rotating shaft 165 and the fourth rotating shaft 166 can be rotatably inserted into the upright plate, and the first gear 161 and the second gear 162 are both located on the side of the upright plate away from the turntable 13.

[0128] The housing 11 is mounted on the box 17. The two housings 11 in the compressor 100 are located at opposite ends of the box 17 in the longitudinal Y direction, and the accommodating space is connected to the interior of the box 17.

[0129] In some embodiments, the top surface of the housing 17 is provided with a through adjustment port 171, and a cover plate 172 is provided on the adjustment port 171. The orthographic projection of the cover plate 172 on the top surface of the housing 17 can at least cover the adjustment port 171, so as to seal the internal space of the housing 17, reduce the possibility of moisture, dust and other substances in the external environment entering the housing 17 and contaminating the rotating components and the housing space, thereby improving the purity of the product obtained after the compressor 100 is produced, and reducing the risk of damage to the compressor 100, thereby extending the service life of the compressor 100.

[0130] In this embodiment, the orthographic projection of the turntable 13 on the top surface of the housing 17 can be located within the adjustment port 171. The cover plate 172 is detachably connected to the top surface of the housing 17, so that the position of the sliding component 14 on the turntable 13 can be adjusted by separating the cover plate 172 from the housing 17.

[0131] For example, in this embodiment of the present disclosure, the cover plate 172 and the housing 17 can be detachably connected by threaded bolts.

[0132] like Figure 9 As shown, in some embodiments, the housing 17 may include a first housing 173, a second housing 174, a first frame 175, and a second frame 176.

[0133] The first frame 175 and the second frame 176 are located on opposite sides of the upright plate in the horizontal direction X. The first frame 175 and the second frame 176 are both arranged around the side periphery of the upright plate, and the inner sidewalls of the first frame 175 and the second frame 176 are both in contact with the side periphery of the upright plate.

[0134] The first housing 173 is located on the side of the first frame 175 opposite to the second frame 176. The side of the first housing 173 close to the first frame 175 can fit completely with the side of the first frame 175 close to the first housing 173 to achieve a seal for the rotating assembly.

[0135] The first box 173 and the first frame 175 can be detachably connected, but are not limited to this; the first box 173 and the first frame 175 can also be fixedly connected.

[0136] The second box 174 is located on the side of the second frame 176 opposite to the first frame 175. The side of the second box 174 near the second frame 176 can fit completely with the side of the second frame 176 near the second box 174 to achieve a seal on the turntable 13.

[0137] The second box 174 and the second frame 176 can be detachably connected, but are not limited to this; the second box 174 and the second frame 176 can also be fixedly connected.

[0138] In some embodiments, a drive unit 18 may be provided on the housing 17.

[0139] The drive unit 18 can be connected to the first rotating shaft 163 to drive the first rotating shaft 163 to rotate. The first rotating shaft 163 drives the first gear 161 and the second gear 162 to rotate. The second rotating shaft 164 rotates together with the second gear 162. Under the action of the synchronous belt 167, the third rotating shaft 165 can rotate synchronously with the first rotating shaft 163, and the fourth rotating shaft 166 can rotate synchronously with the second rotating shaft 164. This can drive the corresponding turntable 13 to rotate and cause the corresponding piston 12 to move at a certain frequency so that the gas pressure in the corresponding accommodating space meets the pressure required by the gas.

[0140] However, it is not limited to this. The drive unit 18 can also be connected to the second rotating shaft 164 to drive the second rotating shaft 164 to rotate.

[0141] In some embodiments, the drive element 18 may be disposed on the first housing 173 to facilitate the connection between the drive element 18 and the first rotating shaft 163.
