Description

Technical Field

[0001] This invention relates to the field of screw assembly technology, specifically a screw rotor assembly for an energy-saving air compressor. Background Technology

[0002] The core compression component of a screw air compressor is the built-in screw rotor assembly, which includes one or two screw rotors machined with helical grooves. The screw rotor assembly performs high-speed meshing rotation within a sealed cylinder. Through the periodic change in the volume of the helical grooves, it achieves the step-by-step compression of the intake gas and finally outputs compressed air that meets the preset pressure requirements.

[0003] During the actual operation of the screw rotor assembly, the mechanical friction heat generated by the meshing and rotation of the screw rotor and the thermodynamic heat released during gas compression will cause the internal temperature of the air compressor to rise. Screw air compressors usually use lubricating oil for heat dissipation, but the heat is usually directly discharged to the external environment without recovering and utilizing the heat energy, which is not conducive to energy saving.

[0037] 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.

[0038] Please see Figure 1-8 In this embodiment of the invention, an energy-saving air compressor screw rotor assembly includes a screw module 100, a heat exchange module 200 provided in the screw module 100, a connecting shaft 110, a screw component 120 fixedly connected to the connecting shaft 110, a heat exchange tube 130 fixedly connected inside the connecting shaft 110, a heat exchange tube 140 rotatably connected inside the heat exchange tube 130, a limiting tube 131 rotatably connected to the end of the heat exchange tube 130 and rotatably connected to the connecting shaft 110, and a plurality of communicating grooves opened at one end of the heat exchange tube 140 located inside the heat exchange tube 130.

[0039] The heat exchange module 200 includes a heat exchange cylinder 210, inside which a spiral frame 211 is fixedly connected. A spiral tube 212 is fixedly connected to the spiral frame 211. An adjusting cylinder 250 is disposed inside the spiral frame 211, and an L-shaped tube 280 is disposed inside the adjusting cylinder 250. The adjusting cylinder 250 has a spiral groove 251 that is slidably connected to the spiral frame 211. The spiral frame 211 supports the adjusting cylinder 250 through the spiral groove 251 and screws the adjusting cylinder 250 onto the spiral frame 211 through the spiral groove 251. Both ends of the spiral tube 212 are connected to conveying devices. Pipe 213, conveying pipe 213 is connected to connecting pipe 300, heat exchange pipe 240 and limiting pipe 131 are both connected to adjacent connecting pipe 300, heat exchange cylinder 210 is provided with water pipe 214 at the top and bottom of corresponding spiral frame 211, water pipe 214 corresponds to the side of spiral frame 211, rotating cylinder 215 is rotatably connected inside heat exchange cylinder 210, adjusting cylinder 250 is fixedly connected with several limiting rods 253, several limiting rods 253 are fixedly connected with limiting rings 252 that are slidably connected inside rotating cylinder 215, limiting rings 252 can slide up and down along the inside of rotating cylinder 215.

[0040] Specifically, the connecting shaft 110 can be installed inside the air compressor, while the ends of the limiting tube 131 and the second heat exchange tube 140 are both fixed on the air compressor. When the air compressor power mechanism drives the connecting shaft 110 to rotate, the connecting shaft 110 can drive the first heat exchange tube 130 to rotate, so that the first heat exchange tube 130 rotates relative to the limiting tube 131 and rotates relative to the second heat exchange tube 140.

[0041] Coolant can be introduced into the spiral tube 212, and a delivery pump is installed on a connecting pipe 300. The delivery pump can deliver the coolant in the spiral tube 212 to the heat exchange tube 240 through the connecting pipe 300 and the bottom delivery pipe 213. The coolant in the heat exchange tube 240 can enter the space between the inside of the heat exchange tube 130 and the outside of the heat exchange tube 240 through the connecting groove. Then, the coolant can enter the other connecting pipe 300 through the limiting pipe 131, and then enter the top delivery pipe 213 from the other connecting pipe 300, and then enter the spiral tube 212. Thus, the delivery pump makes the coolant circulate within the spiral tube 212 and the connecting shaft 110. The circulating flow allows cold water to be introduced into the spiral frame 211 through the bottom water pipe 214, causing the cold water to flow upward along the inside of the spiral frame 211. The coolant can heat the cold water through the spiral tube 212, and the heated water can be discharged through the water pipe 214, thus allowing the coolant and water to exchange heat. The cooled coolant can be transported back into the connecting shaft 110, where the connecting shaft 110 and the spiral component 120 are circulated and cooled by the coolant, and the water is heated through heat exchange. The hot water can then be used for process heating or domestic water, which is beneficial for the recovery and utilization of the heat generated by the operation of the spiral component 120 and the connecting shaft 110, and is beneficial for the energy saving of the air compressor.

[0042] The L-shaped tube 280 corresponds to the middle of the spiral frame 211. When water is heated and hot water is discharged through the top water pipe 214, hot water of different temperatures can be discharged through the L-shaped tube 280. According to the operating conditions of the air compressor and the required hot water temperature, the regulating cylinder 250 can be rotated along the spiral frame 211 to adjust the height of the L-shaped tube 280, so that the L-shaped tube 280 corresponds to different positions of the spiral frame 211, thereby changing the flow path of water entering the L-shaped tube 280. This allows adjustment of the temperature of the hot water discharged from the L-shaped tube 280. When the L-shaped tube 280 rotates, the limiting rod 253 can drive the limiting ring 252 to rotate, thereby causing the limiting ring 252 to move up and down along the inside of the rotating cylinder 215, and causing the rotating cylinder 215 to rotate inside the heat exchange cylinder 210. In this way, the bottom of the regulating cylinder 250 can be limited by the rotating cylinder 215 and the limiting ring 252.

[0043] Example 1

[0044] like Figure 3 and Figure 4 As shown, in this embodiment, a linkage rod 260 is rotatably connected inside the heat exchange cylinder 210, a drive mechanism 220 is provided at the bottom of the heat exchange cylinder 210, a linkage cylinder 254 is provided inside the adjusting cylinder 250, and a plurality of locking rods 255 are fixedly connected inside the linkage cylinder 254. The linkage rod 260 has a plurality of locking grooves 261 that are slidably connected to adjacent locking rods 255. The locking rods 255 can slide along the inside of the locking grooves 261. A positioning ring 256 is fixedly connected to the linkage cylinder 254 and is fixedly connected to the inside of the adjusting cylinder 250. The adjusting cylinder 250 can support and position the linkage cylinder 254 through the positioning ring 256.

[0045] In specific implementation, the linkage rod 260 can be driven to rotate by the drive mechanism 220. The linkage rod 260 can drive the linkage cylinder 254 to rotate through the locking groove 261 and the locking rod 255. The linkage cylinder 254 can drive the adjusting cylinder 250 to rotate through the positioning ring 256, so that the adjusting cylinder 250 rotates along the spiral frame 211, thereby adjusting the height of the adjusting cylinder 250 and changing the position of the L-shaped tube 280. When the L-shaped tube 280 moves up and down, the locking rod 255 can slide along the locking groove 261, thereby allowing the adjusting cylinder 250 to rotate smoothly.

[0046] like Figure 6 As shown, in this embodiment, the adjusting cylinder 250 is fixedly connected to the cleaning frame 270, the spiral tube 212 passes through the inside of the cleaning frame 270, and the inside of the cleaning frame 270 is provided with cleaning bristles.

[0047] In practice, when it is necessary to clean the spiral tube 212, cleaning fluid can be introduced between the spiral frame 211 and the spiral tube 212, and the adjusting cylinder 250 can be rotated along the spiral frame 211. This allows the cleaning frame 270 to move along the spiral tube 212, and the cleaning bristles in the cleaning frame 270 can clean the side wall of the spiral tube 212, which helps to improve the cleaning effect of the spiral tube 212.

[0048] like Figure 7-9 As shown, in this embodiment, a corrugated pipe 281 is fixedly connected to the top of the L-shaped pipe 280, a top plate 230 is fixedly connected to the heat exchange cylinder 210, a fixed pipe 231 is provided on the top plate 230, a rotating pipe 282 is fixedly connected to the corrugated pipe 281 and rotatably connected to the fixed pipe 231, a positioning pipe 232 is fixedly connected to the top plate 230 and fixedly connected to the fixed pipe 231, the top plate 230 can support the positioning pipe 232, the positioning pipe 232 can position the fixed pipe 231, a plurality of locking rods 257 are fixedly connected inside the adjusting cylinder 250, a positioning frame 283 is fixedly connected to the rotating pipe 282 and slidably connected to the locking rods 257, and the positioning frame 283 is slidably connected to the inside of the adjusting cylinder 250.

[0049] In practice, the hot water in the L-shaped pipe 280 can enter the corrugated pipe 281, then enter the fixed pipe 231 through the rotating pipe 282, and then enter the positioning pipe 232. When the adjusting cylinder 250 rotates, it can drive the L-shaped pipe 280 to rotate. The adjusting cylinder 250 can drive the positioning frame 283 to rotate through the second locking rod 257. The positioning frame 283 can drive the rotating pipe 282 to rotate relative to the fixed pipe 231, thereby keeping the corrugated pipe 281 rotating with the adjusting cylinder 250. When the adjusting cylinder 250 moves up or down, the corrugated pipe 281 can be extended or contracted, and the second locking rod 257 can slide relative to the positioning frame 283.

[0050] Example 2

[0051] Based on Example 1, such as Figure 4 As shown, in this embodiment, the drive mechanism 220 includes a support frame 221, a drive motor 222, a transmission shaft 223, a linkage shaft 224, a worm gear 225, and a worm wheel 226;

[0052] The support frame 221 is fixedly connected to the bottom surface of the heat exchange cylinder 210. The drive motor 222 is fixedly connected inside the support frame 221. The transmission shaft 223 is located inside the support frame 221. The output end of the drive motor 222 is connected to the transmission shaft 223. Two partitions are fixedly connected inside the support frame 221. The transmission shaft 223 is rotatably connected to the two partitions. The partitions can position the transmission shaft 223. The linkage shaft 224 is rotatably connected inside the support frame 221. The linkage shaft 224 is fixedly connected to the bottom end of the linkage rod 260. The worm 225 is fixedly sleeved on the transmission shaft 223. The worm wheel 226 is fixedly sleeved on the linkage shaft 224. The worm 225 and the worm wheel 226 mesh and transmit power. The angle of the linkage shaft 224 can be limited by the worm 225 and the worm wheel 226, thereby preventing the linkage rod 260 and the adjusting cylinder 250 from rotating and maintaining the height of the adjusting cylinder 250.

[0053] In practice, the drive motor 222 can drive the transmission shaft 223 to rotate. The transmission shaft 223 can drive the linkage shaft 224 to rotate through the worm gear 225 and worm wheel 226. The linkage shaft 224 can drive the linkage rod 260 to rotate, which in turn causes the linkage rod 260 to drive the linkage cylinder 254 to rotate through the locking groove 261 and locking rod 255, thereby causing the adjusting cylinder 250 to rotate and adjusting the height of the L-shaped tube 280.

[0054] like Figure 9 As shown, in this embodiment, a three-way valve 240 is provided at the top of the positioning tube 232, and the three-way valve 240 is connected to a connecting tube 1 241 and a connecting tube 242.

[0055] In specific implementation, the positioning tube 232 can be connected only to the connecting tube 1 241 through the three-way valve 240, so that the hot water in the positioning tube 232 can be discharged from the connecting tube 1 241. The positioning tube 232 can also be connected only to the connecting tube 242 through the three-way valve 240, so that while cold water is introduced into the bottom water pipe 214, cold water can also be introduced into the connecting tube 242. The cold water can enter the positioning tube 232 through the three-way valve 240, and then enter the spiral frame 211 through the L-shaped pipe 280. This can increase the temperature difference between the cold water and the coolant in the middle of the spiral frame 211, which is beneficial to improving the cooling effect of the coolant and the cooling effect of the connecting shaft 110 and the spiral component 120.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
