Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a compressor main unit. Background Technology

[0002] As a core power device in refrigeration systems, industrial gas supply systems, and other fields, the compressor's operational stability directly determines the overall system's efficiency and service life. During the compressor's operation, the gaseous working fluid is prone to entraining liquid components such as liquid refrigerant and lubricating oil during compression and transportation.

[0003] Existing compressor main units typically incorporate gas-liquid separation structures along the gas flow path. Their core principles are mostly based on gravity settling or simple inertial collisions. By placing a single baffle or expanded chamber within the gas channel, liquid particles in the airflow are separated due to inertia impacting the wall. However, the lack of orderly guidance in the airflow path during separation leads to turbulent eddies after the gas enters the separation area. Some liquid particles are caught in these eddies and cannot effectively contact the separation wall, resulting in unstable separation. Utility Model Content

[0004] To solve the above problems, this utility model provides a compressor main unit.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a compressor main unit, including a housing and a screw rotor assembly disposed within the housing, a mounting cylinder communicating with the housing on one side, a connecting pipe communicating with the air outlet of the screw rotor assembly inside the mounting cylinder, a through pipe inside the connecting pipe, a mounting ring fixedly sleeved on the end of the through pipe away from the screw rotor assembly, a guide box communicating with the through pipe and having an open top on the mounting ring, a partition vertically disposed at the top of the mounting cylinder, and separation plates horizontally disposed on both inner walls of the mounting cylinder.

[0006] By adopting the above technical solution, which includes a housing, screw rotor assembly, connecting pipe, and through pipe, gas flows upward from the top opening of the guide box after passing through the connecting pipe. Constrained by the baffle, it moves downward along the arc-shaped inner wall of the mounting cylinder and is subsequently blocked by the separation plate. This process effectively disturbs and separates the gas. During the gas flow, the liquid in the gas stream adheres to the inner wall of the mounting cylinder, the baffle, and the separation plate, significantly improving the orderliness and efficiency of gas processing inside the main unit and ensuring the stability of gas-liquid separation.

[0007] Furthermore, a fixing ring is fixedly sleeved on the outside of the connecting pipe, and a sealing pipe is provided on the fixing ring. The sealing pipe is connected to the mounting ring, the end of the connecting pipe is spaced apart from the mounting ring, and the bottom of the sealing pipe is provided with a discharge port.

[0008] By adopting the above technical solution, a fixed ring and a closed pipe are set. By setting a fixed ring outside the connecting pipe and using the fixed ring to install the closed pipe and connect it to the mounting ring, the end of the connecting pipe and the mounting ring form a spaced arrangement structure. This space allows some liquid or impurities carried by the gas in the connecting pipe and through the pipe to settle here during the flow. The outlet at the bottom of the closed pipe can discharge the settled liquid or impurities in a timely manner, ensuring the smooth flow of gas transmission channels. At the same time, it reduces the wear of impurities on subsequent components and extends the service life of the main unit.

[0009] Furthermore, the guide box is located directly below the area between the partition and the bottom of the mounting cylinder.

[0010] By adopting the above technical solution, the guide box is placed directly below the area between the partition and the bottom of the mounting cylinder, which can accurately guide the gas transported through the pipe to a specific area inside the mounting cylinder.

[0011] Furthermore, the guide box includes a base plate and three side plates disposed on the base plate, the three side plates being inclined from bottom to top away from the end of the through tube.

[0012] By adopting the above technical solution, the three side plates are inclined from bottom to top away from the end of the pipe, which can expand the diffusion range of the gas, so that the gas can contact the subsequent components more evenly and improve the separation effect.

[0013] Furthermore, a discharge hole is provided on the base plate.

[0014] By adopting the above technical solution, the discharge hole allows the liquid separated from the gas during the gas guiding process to be directly discharged from the guiding box through the discharge hole, thus avoiding the accumulation of these impurities in the guiding box.

[0015] Furthermore, the tube is provided with a plurality of guide vanes circumferentially spaced on the inner wall of one end of the screw rotor assembly, and a connecting post is provided on the plurality of guide vanes.

[0016] By adopting the above technical solution, and setting guide vanes and connecting columns, the guide vanes can guide and rectify the gas that has just entered the pipe, effectively improving the gas flow state and reducing the eddies and disturbances of the gas in the pipe.

[0017] Furthermore, a conical block is provided near one end of the connecting post adjacent to the screw rotor assembly.

[0018] By adopting the above technical solution, the conical structure of the conical block can guide the gas discharged from the screw rotor assembly, allowing the gas to enter the inside of the pipe more smoothly and reducing the accumulation and impact of gas at the end of the connecting column.

[0019] Furthermore, the top surface of the separation plate is provided with a first arc-shaped plate that connects to the inner wall of the mounting cylinder, and an upper baffle plate is provided on both of the first arc-shaped plates.

[0020] Furthermore, the bottom surface of the separation plate is provided with a second arc-shaped plate that connects to the inner wall of the mounting cylinder, and a lower baffle plate is provided on both second arc-shaped plates.

[0021] Furthermore, the top surface of the separation plate is lower than the top surface of the guide box.

[0022] By adopting the above technical solution, setting the top surface of the separation plate to be lower than the top surface of the guide box, it can be ensured that the gas discharged from the guide box can completely cover the top surface area of ​​the separation plate after entering the installation cylinder, ensuring the effective implementation of the separation and filtration process and improving the comprehensiveness and reliability of gas treatment.

[0023] In summary, this utility model has the following beneficial effects: In this application, a housing, screw rotor assembly, connecting pipe, and through pipe are provided. After passing through the connecting pipe, the gas rushes upward from the top opening of the guide box. Under the restriction of the partition, it moves downward along the arc-shaped inner wall of the mounting cylinder and is subsequently blocked by the separation plate. This process effectively disturbs and separates the gas. During the gas flow, the liquid in the gas flow adheres to the inner wall of the mounting cylinder, the partition, and the separation plate, significantly improving the orderliness and efficiency of gas processing inside the main unit and ensuring the stability of gas-liquid separation.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-5 As shown, this application discloses a compressor main unit, including a housing 10 and a screw rotor assembly 11 disposed within the housing 10. The screw rotor assembly 11 includes a rotor housing, and a female rotor and a male rotor that mesh with each other are rotatably disposed within the rotor housing. The rotation of the female rotor and the male rotor transports external air from the air outlet of the rotor housing into the housing 10. The housing is also provided with corresponding air outlet components, which are prior art and will not be described in detail here.

[0028] Specifically, a mounting cylinder 20 communicating with one side of the housing 10 is provided. A connecting pipe 30 communicating with the air outlet of the screw rotor assembly 11 is provided inside the mounting cylinder 20. A through pipe 31 is provided inside the connecting pipe 30. A mounting ring 32 is fixedly fitted onto the end of the through pipe 31 away from the screw rotor assembly 11. A guide box 40 communicating with the through pipe 31 and open at the top is provided on the mounting ring 32. A partition 21 is vertically arranged at the top of the mounting cylinder 20, and separation plates 22 are horizontally arranged on both inner walls of the mounting cylinder 20. By providing a communicating mounting cylinder 20 on one side of the housing 10, and by providing a gas transmission channel composed of the connecting pipe 30, through pipe 31, mounting ring 32, and guide box 40 within the mounting cylinder 20, the gas discharged from the screw rotor assembly 11 can enter the interior of the mounting cylinder 20 in an orderly manner. Simultaneously, the vertical partition 21 at the top of the mounting cylinder 20 and the horizontal separation plates 22 on both inner walls divide the space within the mounting cylinder 20, providing clear guidance for gas flow. After passing through the connecting pipe 30, the gas rushes upward from the top opening of the guide box 40. Restricted by the partition 21, it moves downward along the arc-shaped inner wall of the mounting cylinder 20, and is subsequently blocked by the separation plate 22. This process effectively disturbs and separates the gas. During the gas flow, the liquid in the gas stream adheres to the inner wall of the mounting cylinder 20, the partition 21, and the separation plate 22, significantly improving the orderliness and efficiency of gas processing inside the main unit and ensuring the stability of gas-liquid separation.

[0029] During installation, a fixing ring 33 is fixedly fitted around the connecting pipe 30. A sealing pipe 34 is mounted on the fixing ring 33 and connected to the mounting ring 32. The ends of the connecting pipe 30 and the mounting ring 32 are spaced apart, and the bottom of the sealing pipe 34 has a discharge port 35. By setting a fixing ring 33 around the connecting pipe 30 and using the fixing ring 33 to mount the sealing pipe 34 and connect it to the mounting ring 32, a spaced arrangement is formed between the ends of the connecting pipe 30 and the mounting ring 32. This space allows some liquid or impurities carried by the gas flowing between the connecting pipe 30 and the pipe 31 to settle. The discharge port 35 at the bottom of the sealing pipe 34 can promptly discharge the settled liquid or impurities, ensuring the smooth flow of the gas transmission channel, reducing wear on subsequent components caused by impurities, and extending the service life of the main unit.

[0030] The guide box 40 is located directly below the area between the partition 21 and the bottom of the mounting cylinder 20. Positioning the guide box 40 directly below this area accurately guides the gas delivered through the pipe 31 to a specific area within the mounting cylinder 20, preventing the gas from diffusing randomly within the cylinder. This ensures the gas is concentrated within the space defined by the partition 21 and the cylinder bottom for subsequent processing, improving the targeting and efficiency of gas treatment, preventing incomplete treatment due to gas diffusion, and guaranteeing the gas treatment effect of the main unit. The guide box 40 includes a base plate 41 and three side plates 42 mounted on the base plate 41. The three side plates 42 are inclined from bottom to top away from the end of the pipe 31. The three side plates 42 are inclined from bottom to top away from the end of the through pipe 31. On the one hand, this expands the gas diffusion range, allowing the gas to contact subsequent components more evenly and improving the separation effect. On the other hand, the inclined side plates 42 have a certain buffering effect on the gas, reducing the flow velocity of the gas when entering the mounting cylinder 20, reducing the impact of gas on the internal components of the mounting cylinder 20, and also facilitating the settling of impurities in the gas. The bottom plate 41 has a discharge hole 43. The discharge hole 43 allows the liquid separated from the gas to be directly discharged from the guide box 40 during the gas guiding process, avoiding the accumulation of these impurities in the guide box 40. This ensures the unobstructed flow inside the guide box 40 and prevents the liquid from re-entering the subsequent transmission path with the gas, further improving the gas purification effect and reducing the workload of subsequent separation components.

[0031] In the specific configuration, several guide vanes 50 are circumferentially spaced on the inner wall of one end of the pipe 31 near the screw rotor assembly 11. A connecting post 51 is shared on each of the guide vanes 50, and the connecting post 51 is concentrically arranged with the pipe 31. The guide vanes 50, connected as a whole by the connecting post 51, guide and rectify the gas entering the pipe 31, effectively improving the gas flow state and reducing eddies and disturbances within the pipe. Simultaneously, the connecting post 51 enhances the structural stability of the guide vanes 50, preventing deformation or damage under high-speed airflow impact, thus ensuring the long-term stable operation of the guiding function. A conical block 52 is also provided near the end of the connecting post 51 near the screw rotor assembly 11. The conical structure of the conical block 52 guides the gas discharged from the screw rotor assembly 11, allowing the gas to enter the through pipe 31 more smoothly, reducing gas accumulation and impact at the end of the connecting column 51, lowering gas flow resistance, and thus improving gas delivery efficiency. At the same time, the conical structure also reduces the eddies formed by the airflow in this area, further optimizing the gas flow state in conjunction with the guide vane 50. The top surface of the separation plate 22 is provided with a first arc-shaped plate 60 that connects to the inner wall of the mounting cylinder 20. An upper baffle plate 61 is provided on both first arc-shaped plates 60. The upper baffle plate 61 contacts the inner wall of the mounting cylinder 20 on both sides and the separation plate 22 at its bottom. The bottom surface of the separation plate 22 is provided with a second arc-shaped plate 70 that connects to the inner wall of the mounting cylinder 20. A lower baffle plate 71 is provided on both second arc-shaped plates 70. The lower baffle plate 71 contacts the inner wall of the mounting cylinder 20 on both sides and the separation plate 22 at its top. When the airflow comes into contact with the upper baffle plate 61 or the lower baffle plate 71, the airflow direction is forced to change, such as bypassing the edge of the upper baffle plate 61 or the lower baffle plate 71 or passing through the gap above or below it. Because the density of the liquid droplets entrained in the airflow is much greater than that of the gas, the liquid droplets cannot quickly change direction with the gas due to inertia and will collide with the sides of the upper baffle plate 61 or the lower baffle plate 71. After impact, the droplets converge into a liquid stream under the influence of surface tension and gravity, flowing along the surface of the upper baffle 61 or lower baffle 71 or downwards, eventually dripping into the liquid accumulation area at the bottom of the mounting cylinder 20. Meanwhile, the gas smoothly bypasses the upper baffle 61 or lower baffle 71 and continues to flow, thus achieving effective gas-liquid separation. The top surface of the separation plate 22 is lower than the top surface of the guide box 40. Setting the top surface of the separation plate 22 lower than the top surface of the guide box 40 ensures that the gas discharged from the guide box 40 completely covers the top surface area of ​​the separation plate 22 after entering the mounting cylinder 20, ensuring the effective implementation of the separation and filtration process and improving the comprehensiveness and reliability of gas treatment.

[0032] The operating principle of a compressor main unit in this embodiment is as follows: First, in the screw rotor assembly 11, the female and male rotors meshing with each other inside the rotor housing rotate relative to each other. The change in volume of the rotor meshing gap generates an air intake effect, drawing external air into the rotor housing. Subsequently, the female rotor and the male rotor continue to rotate, compressing the intake air. The compressed gas is discharged from the air outlet of the rotor housing and enters the connecting pipe 30 connected to the air outlet inside the mounting cylinder 20. Next, some gas flows through the connecting pipe 30 into the through pipe 31, and some gas flows between the connecting pipe 30 and the through pipe 31 into the closed pipe 34. The conical block 52 in the through pipe 31 first guides the gas to ensure smooth flow. Then, several guide vanes 50 guide and rectify the gas flow, reducing eddies and disturbances and optimizing the gas flow state. After that, the rectified gas enters the guide box 40 and rushes upward through the top opening of the guide box 40. Under the restriction of the vertical partition 21 at the top of the mounting cylinder 20, the gas moves downward along the arc-shaped inner wall of the mounting cylinder 20. During this process, it is blocked by the horizontal separation plates 22 on both sides of the inner wall of the mounting cylinder 20. During this process, the gas is fully disturbed, and the liquid in it adheres to the inner wall of the mounting cylinder 20, the partition 21, and the separation plates 22. Meanwhile, the upper baffle plate 61 above the separation plate 22 and the lower baffle plate 71 below it are in full contact with the gas, while the gap between the connecting pipe 30 and the mounting ring 32 allows some liquid and impurities in the gas to settle. The settled material and the liquid separated in the guide box 40 are discharged through the outlet 35 at the bottom of the closed pipe 34 and the discharge hole 43 on the bottom plate 41 of the guide box 40, respectively. Finally, the clean gas that has completed gas-liquid separation is discharged through the gas outlet component on the housing 10, realizing the gas processing and transportation.
