Description

Technical Field

[0001] This application relates to the technical field of compressors, and in particular to a high-efficiency and stable twin-rotor steam compressor. Background Technology

[0002] Currently, steam compressors form a dynamic sealed cavity through the cooperation of the rotor and the casing. When low-pressure, low-temperature steam enters the cavity from the inlet, the rotation of the rotor will drive the volume of the sealed cavity to periodically contract. During this process, the steam molecules are continuously squeezed, the distance between the molecules is reduced, and the kinetic energy is converted into pressure energy and heat energy, so that the pressure and temperature of the steam increase simultaneously.

[0003] However, current steam compressors experience rotor vibration at high speeds, which can cause abnormal friction or collision between the rotor and the cylinder, leading to excessive wear of the rotor and shortening its service life. Utility Model Content

[0004] The purpose of this application is to provide a high-efficiency and stable twin-rotor steam compressor, which has the advantages of easy adjustment of rotor mass distribution, thereby reducing rotor vibration at high speed and improving service life. It solves the problem that current steam compressors have rotor vibration at high speed, which leads to abnormal friction or collision between the rotor and cylinder, resulting in excessive wear of the rotor and shortened service life.

[0005] This application provides a high-efficiency and stable twin-rotor steam compressor with the following technical solution: It includes a cylinder body and a first rotating shaft. A cylinder is fixedly connected to the bottom of the cylinder body. Two compression chambers are arranged in a mirror-like configuration inside the cylinder. Two symmetrically arranged rotors are fixedly connected to the bottom of the outer wall of the first rotating shaft. A sliding cavity is formed on one side of each rotor. First sliding grooves are formed on both sides of the inner walls of each sliding cavity. Sliding rods are fixedly connected to each of the four first sliding grooves. A first motor is fixedly connected to the upper end of each of the two sliding cavities. Threaded rods are fixedly connected to the output ends of each of the two first motors via couplings. Counterweights are threadedly connected to the outer walls of each of the two threaded rods. The two counterweights are slidably disposed on the outer walls of the two sliding rods and located inside the sliding cavities. The ends of the two threaded rods furthest from the first motors are rotatably connected to the rotors. A driven gear is fixedly connected to the upper end of the first rotating shaft.

[0006] By adopting the above technical solution, the two mirror-distributed compression chambers inside the cylinder cooperate with the two symmetrically arranged rotors on the first rotating shaft. When the first rotating shaft drives the rotors to rotate, the two rotors can compress the steam entering through the air inlet of the cylinder in their respective compression chambers, thereby improving the steam compression efficiency. At the same time, the sliding chamber inside the rotor provides installation space for the counterweight, and the sliding rod in the first sliding groove guides the counterweight. When the first motor drives the threaded rod to rotate, the counterweight will move smoothly along the sliding rod in the sliding chamber, thereby adjusting the center of gravity of the rotor, counteracting the unbalanced centrifugal force generated by rotation, reducing the vibration of the rotor during rotation, and avoiding abnormal friction or collision between the rotor and the cylinder. This improves the stability of operation and the compression effect while extending the service life of the equipment.

[0007] Preferably, a vibration sensor is fixedly connected to the inner wall of the cylinder, and the vibration sensor is electrically connected to two first motors respectively.

[0008] By adopting the above technical solution, the vibration sensor fixed on the inner wall of the cylinder is electrically connected to the two first motors. When vibration occurs during operation, the vibration sensor can detect the vibration in real time and transmit the signal to the first motor. The first motor will then drive the threaded rod to adjust the position of the counterweight, balance the center of gravity of the rotor, reduce the vibration amplitude, and further improve the stability during operation.

[0009] Preferably, a bearing bracket is fixedly connected inside the cylinder body, and the first rotating shaft is rotatably disposed inside the bearing bracket.

[0010] By adopting the above technical solution, the first rotating shaft is installed inside the cylinder body through the bearing bracket inside the cylinder body. When the first rotating shaft rotates, the bearing bracket can provide stable support for it, reduce the shaking or deviation that occurs during the rotation of the first rotating shaft, and make the rotation of the rotor driven by the first rotating shaft in the compression chamber more stable, avoiding the impact of the steam compression effect due to the instability of the rotating shaft.

[0011] Preferably, a mounting base is fixedly connected to one side of the inner wall of the cylinder, a second motor is fixedly connected inside the mounting base, a second rotating shaft is fixedly connected to the output end of the second motor via a coupling, a drive gear is fixedly connected to the bottom end of the outer wall of the second rotating shaft, and two impellers that are equidistantly distributed are fixedly connected to the upper end of the outer wall of the second rotating shaft.

[0012] By adopting the above technical solution, the second motor is fixed on one side of the inner wall of the cylinder by a mounting base. The mounting base provides a stable installation foundation for the second motor, preventing it from becoming loose during operation. When the second motor starts, its output end drives the second shaft to rotate through a coupling. When the second shaft rotates, it synchronously drives the drive gear at the bottom and the two impellers at the top to rotate. The drive gear can cooperate with the driven gear on the first shaft to realize power transmission, ensuring that the rotor can rotate stably to perform compression operations. The impellers can help discharge the compressed steam to the outside of the cylinder, making the power transmission and steam treatment process of the entire compressor more coherent and improving the overall operating efficiency of the equipment.

[0013] Preferably, an exhaust pipe is fixedly connected to one side of the upper end of the cylinder.

[0014] By adopting the above technical solution, the exhaust pipe fixed on one side of the upper end of the cylinder can provide an exhaust channel for the compressed steam. After the steam completes the compression operation in the compression chamber, it is discharged into the cylinder through the exhaust end inside the cylinder. Then, with the assistance of two impellers, it is discharged to the outside of the cylinder through the exhaust pipe, which avoids the compressed steam from stagnating inside the cylinder, ensures a smoother steam delivery process after compression, further guarantees the continuity of the entire steam treatment process, and improves the steam discharge efficiency.

[0015] Preferably, a second sliding groove is provided on one side of the inner wall of each of the two compression chambers, and four springs arranged in a linear array are fixedly connected to one side of each of the two second sliding grooves. Each of the multiple springs is fixedly connected to a sliding plate at the end away from the second sliding groove in groups of four, and both sliding plates are in contact with the outer wall of the rotor.

[0016] By adopting the above technical solution, a spring with a straight distribution is fixedly connected in the second sliding groove opened on one side of the inner wall of the compression chamber, and a sliding plate is fixedly connected at the end away from the second sliding groove. When the rotor rotates in the compression chamber, the spring will always push the sliding plate to tightly fit the outer surface of the rotor, ensuring the sealing performance of the compression chamber and preventing steam leakage during the compression process. Furthermore, the elasticity of the spring reduces the friction between the sliding plate and the rotor, avoiding excessive wear that could affect the service life, thereby ensuring the stable and efficient operation of steam compression.

[0017] Preferably, the driving gear meshes with the driven gear, and both impellers are rotatably disposed inside the exhaust pipe.

[0018] By adopting the above technical solution, the driving gear and the driven gear mesh with each other. When the second motor drives the second shaft to rotate, the driving gear will drive the driven gear to rotate, thereby making the first shaft and rotor run stably and realizing the steam compression operation.

[0019] Preferably, the axes of the two rotors are eccentrically set to the axis of the first rotor, and both rotors are rotatably disposed inside the compression chamber.

[0020] By adopting the above technical solution, the axes of the two rotors are eccentrically set with respect to the axis of the first shaft, and the rotors are rotated inside the compression chamber. When the first shaft drives the rotors to rotate, this eccentric structure allows the rotors to effectively compress the steam entering the compression chamber, increasing the pressure and temperature of the steam, improving the efficiency of steam treatment, and meeting higher compression requirements.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This high-efficiency and stable twin-rotor steam compressor utilizes a combination of mirror-distributed compression chambers within the cylinder and symmetrical rotors on a first shaft. The eccentric arrangement of the rotors and shaft, along with the sealing achieved by spring-driven vanes in a second groove, enables dual-path steam compression, improving processing efficiency. Simultaneously, a vibration sensor detects vibration in real time and transmits the signal to a first motor. The first motor then drives a threaded rod to adjust the position of the counterweight, balancing the rotor's center of gravity and reducing vibration amplitude. Combined with the stable support of the bearing bracket for the first shaft, vibration during operation is further reduced. Furthermore, the second motor drives the rotor and impeller in the exhaust pipe through the meshing of a drive gear and a driven gear, making the compression and exhaust processes more seamless. This enhances operational stability and equipment durability while improving compression efficiency. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5This application will be described in further detail below.

[0025] Example 1: A high-efficiency and stable twin-rotor steam compressor, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a cylinder body 1 and a first rotating shaft 4. A cylinder 2 is fixedly connected to the bottom of the cylinder body 1. Two compression chambers 3 are mirror-arranged inside the cylinder 2. Two symmetrically arranged rotors 5 are fixedly connected to the bottom of the outer wall of the first rotating shaft 4. When the first rotating shaft 4 drives the rotors 5 to rotate, the two rotors 5 can compress the steam entering through the air inlet of the cylinder 2 in their respective compression chambers 3, improving the steam compression efficiency. A sliding chamber 6 is provided on one side of each rotor 5, providing installation space for the rotors 5. First sliding grooves 7 are provided on both sides of the inner wall of each of the two sliding chambers 6. Sliding rods 8 are fixedly connected to the four first sliding grooves 7. The upper ends of the two sliding chambers 6 are fixed... The first motor 9 is connected to the output end of each of the two first motors 9, and threaded rods 10 are fixedly connected to the output ends of the two threaded rods 10 via couplings. Counterweights 11 are threadedly connected to the outer walls of the two threaded rods 10. When the first motor 9 drives the threaded rods 10 to rotate, the counterweights 11 will move smoothly along the slide rods 8 in the sliding cavity 6, thereby adjusting the center of gravity of the rotor 5, counteracting the unbalanced centrifugal force generated by rotation, reducing the vibration of the rotor 5 during rotation, and preventing abnormal friction or collision between the rotor 5 and the cylinder 2. The two counterweights 11 are slidably set on the outer walls of the two slide rods 8 and are located inside the sliding cavity 6. The ends of the two threaded rods 10 away from the first motor 9 are rotatably connected to the rotor 5. A driven gear 12 is fixedly connected to the upper end of the first rotating shaft 4.

[0026] Example 2: A high-efficiency and stable twin-rotor steam compressor, referring to... Figure 4 and Figure 5 A vibration sensor 13 is fixedly connected to the inner wall of the cylinder 1. The vibration sensor 13 is electrically connected to two first motors 9. When vibration occurs during operation, the vibration sensor 13 can sense the vibration in real time and transmit the signal to the first motors 9. The first motors 9 will then drive the threaded rod 10 to adjust the position of the counterweight 11, balance the center of gravity of the rotor 5, reduce the vibration amplitude, and further improve the stability during operation. A bearing bracket 14 is fixedly connected inside the cylinder 1. The first rotating shaft 4 is rotatably installed inside the bearing bracket 14. The first rotating shaft 4 is installed inside the cylinder 1 through the bearing bracket 14 inside the cylinder 1. When the first rotating shaft 4 rotates, the bearing bracket 14 can provide stable support for it, reduce the shaking or deviation that occurs during the rotation of the first rotating shaft 4, and make the rotation of the rotor 5 driven by the first rotating shaft 4 in the compression chamber 3 more stable, avoiding the impact of unstable rotating shaft on the steam compression effect.

[0027] Reference Figure 1 , Figure 4 and Figure 5 A mounting base 15 is fixedly connected to one side of the inner wall of the cylinder 1. A second motor 16 is fixedly connected inside the mounting base 15. The output end of the second motor 16 is fixedly connected to a second rotating shaft 17 via a coupling. A drive gear 18 is fixedly connected to the bottom of the outer wall of the second rotating shaft 17. Two impellers 19, evenly distributed, are fixedly connected to the upper end of the outer wall of the second rotating shaft 17. The second motor 16 is fixed to one side of the inner wall of the cylinder 1 via the mounting base 15. The mounting base 15 provides a stable mounting foundation for the second motor 16, preventing it from loosening during operation. When the second motor 16 starts, its output end drives the second rotating shaft 17 to rotate via the coupling. When the second rotating shaft 17 rotates, it synchronously drives the drive gear 18 at the bottom and the two impellers 19 at the top to rotate. The drive gear 18 can engage with the driven gear 1 on the first rotating shaft 4. 2. The rotor 5 is stably rotated to perform compression operations, while the impeller 19 assists in discharging the compressed steam to the outside of the cylinder 1, making the power transmission and steam treatment process of the compressor more continuous and improving the overall operating efficiency of the equipment. An exhaust pipe 20 is fixedly connected to one side of the upper end of the cylinder 1. The exhaust pipe 20 provides a discharge channel for the compressed steam. After the steam completes the compression operation in the compression chamber 3, it is discharged into the cylinder 1 through the outlet end inside the cylinder 2. Then, with the assistance of the two impellers 19, it is discharged to the outside of the cylinder 1 through the exhaust pipe 20, avoiding the stagnation of compressed steam inside the cylinder 1, ensuring a smoother steam delivery process after compression, further ensuring the continuity of the entire steam treatment process, and improving the steam discharge efficiency.

[0028] Reference Figure 2 , Figure 4 and Figure 5Each of the two compression chambers 3 has a second sliding groove 21 on one side of its inner wall. Four springs 22 arranged in a linear array are fixedly connected to one side of each second sliding groove 21. Each spring 22, arranged in groups of four, has a sliding plate 23 fixedly connected to its end furthest from the second sliding groove 21. Both sliding plates 23 are in contact with the outer wall of the rotor 5. The springs 22, arranged in a linear array, are fixedly connected within the second sliding groove 21 on one side of the inner wall of the compression chamber 3, with the sliding plate 23 fixedly connected to its end furthest from the second sliding groove 21. When the rotor 5 rotates within the compression chamber 3, the springs 22 constantly push the sliding plates 23 to tightly adhere to the outer surface of the rotor 5, ensuring the sealing performance of the compression chamber 3 and preventing steam leakage during compression. Furthermore, the elasticity of the springs 22 reduces friction between the sliding plates 23 and the rotor 5, preventing excessive wear and affecting service life, thus ensuring stable and efficient steam compression operations. The driving gear 18 meshes with the driven gear 12. Both impellers 19 are rotatably disposed inside the exhaust pipe 20. The driving gear 18 and the driven gear 12 mesh with each other. When the second motor 16 drives the second rotating shaft 17 to rotate, the driving gear 18 will drive the driven gear 12 to rotate, thereby driving the first rotating shaft 4 and the rotor 5 to operate stably, realizing the steam compression operation. The axes of the two rotors 5 are eccentrically set with respect to the axis of the first rotating shaft 4. Both rotors 5 are rotatably disposed inside the compression chamber 3. When the first rotating shaft 4 drives the rotors 5 to rotate, this eccentric structure allows the rotors 5 to effectively compress the steam entering the compression chamber 3, increasing the steam pressure and temperature, improving the efficiency of steam treatment, and meeting higher compression requirements.

[0029] The implementation principle of this application embodiment is as follows: During operation, the steam delivery pipe is installed at the air inlet end of the cylinder 2. The second motor 16, which is fixed to one side of the inner wall of the cylinder 1 by the mounting base 15, is started. The output end of the second motor 16 drives the second rotating shaft 17 to rotate through the coupling. The driving gear 18 at the bottom of the second rotating shaft 17 rotates accordingly. Since the driving gear 18 meshes with the driven gear 12 at the upper end of the first rotating shaft 4, the driven gear 12 rotates synchronously during the rotation of the driving gear 18. The driven gear 12 drives the bearing bracket of the first rotating shaft 4 inside the cylinder 1. When the first rotating shaft 4 rotates, the two rotors 5, which are symmetrically arranged at the bottom of its outer wall, will rotate synchronously in the compression chamber 3, which is mirror-distributed in the cylinder 2. Since the axis of the rotor 5 is eccentrically set with the axis of the first rotating shaft 4, this eccentric structure allows the rotor 5 to compress the steam entering the compression chamber 3. At the same time, the spring 22 in the second sliding groove 21 on the inner wall of the compression chamber 3 always pushes the sliding plate 23 to stick to the outer wall of the rotor 5, ensuring that the compression chamber 3 is sealed, thereby effectively compressing the steam entering the compression chamber 3 and increasing the pressure and temperature of the steam. During operation, the vibration sensor 13 on the inner wall of the cylinder 1 will detect the vibration in real time. If vibration occurs, the vibration sensor 13 will transmit the signal to the first motor 9 in the sliding cavity 6 of the rotor 5. The first motor 9 drives the threaded rod 10 to rotate, so that the counterweight 11 connected to it by the thread moves smoothly along the slide bar 8 in the slide groove, adjusting the center of gravity of the rotor 5 to counteract the unbalanced centrifugal force and reduce vibration. At the same time, the two impellers 19 at the upper end of the second rotating shaft 17 rotate synchronously inside the exhaust pipe 20. The rotation of the impellers 19 helps the compressed steam to be quickly discharged from the cylinder 1 through the exhaust pipe 20, avoiding the steam from being trapped inside.
