Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a flow guide component for a quick-release centrifugal compressor. Background Technology

[0002] Centrifugal compressors, also known as scroll compressors, are a type of compressor. Their structure and operating principle are similar to centrifugal blowers, but they are always multi-stage. They can achieve higher gas pressure, larger processing capacity, and higher efficiency.

[0003] During the use of centrifugal power, a flow guide component is installed on the outside of the turbine to limit the direction of gas transmission and ensure gas compression efficiency. However, the component is usually designed as an integrated unit, which means that the turbine assembly must be completely disassembled before the flow guide component can be removed from the outside of the turbine, resulting in wasted time when removing the flow guide component. Therefore, we propose a flow guide component for a quick-release centrifugal compressor. Utility Model Content

[0004] To address the shortcomings of existing flow guiding components in quick-release centrifugal compressors, this invention provides a flow guiding component for a quick-release centrifugal compressor. This component consists of a guide plate and an arc-shaped guide plate that are spliced ​​together to form a single unit. This unit is then fitted onto the outside of the turbine. The improved ease of installation and removal of the guide plate and arc-shaped guide plate outside the turbine, along with the separation of the guide plate and arc-shaped guide plate, solves the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a flow guiding assembly for a quick-release centrifugal compressor, including a housing, end caps sleeved at both ends of the housing, an air inlet and an air outlet sequentially installed on the outside of the two sets of end caps, a rotating shaft installed in the middle of the end caps, turbines sleeved at equal intervals on the outside of the rotating shaft, a guide plate sleeved on the outside of the turbine, an arc-shaped guide plate installed at the rear end of the guide plate, connecting plates installed on the sides of the guide plate and the arc-shaped guide plate, and an air outlet pipe obliquely fixedly connected to the rear end of the arc-shaped guide plate.

[0006] Preferably, the outer shell, end cap and air inlet form a sealed box, and an air inlet pipe is connected to the outside of the air inlet, and a compressed gas collection box is connected to the outside of the air outlet.

[0007] Preferably, the rotating shaft passes through the interior of the end cover, and a sealing assembly is provided at the connection between the rotating shaft and the end cover, and a motor is installed on the exterior of a set of the end covers.

[0008] Preferably, a sliding groove is provided on the inner side of the outer shell, a limiting post is fixedly installed on one side of the connecting plate, and the slider and the limiting post installed on the outside of the connecting plate are both sleeved inside the sliding groove.

[0009] Preferably, the arc-shaped guide plate is circular, and the arc-shaped guide plate is sleeved and installed on the side of the turbine, and the guide plate is sleeved and installed on the front end of the turbine.

[0010] Preferably, the arc-shaped guide plate extends to the rear end of the turbine, and a limit buckle is fixedly connected to the rear end of the turbine. The limit buckle is sleeved and installed inside the arc-shaped guide plate.

[0011] Preferably, a protective plate is fixedly connected to the outside of the guide plate, the protective plate is sleeved and installed on the outside of the arc-shaped guide plate, a set of exhaust pipes installed at the rear end of the turbine is arranged at the front end of another set of guide plates, and an air inlet is provided at the front end of the guide plate.

[0012] Compared with the existing quick-release centrifugal compressor's flow guiding assembly, this utility model has the following advantages:

[0013] 1. The flow guiding assembly of this quick-release centrifugal compressor is installed outside the turbine by a guide plate and an arc-shaped guide plate. During the process of the turbine being sleeved outside the rotating shaft, the positions of the guide plate and the arc-shaped guide plate are adjusted synchronously to ensure the convenience and stability of the assembly and disassembly of the guide plate and the arc-shaped guide plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A flow guiding assembly for a quick-release centrifugal compressor includes a housing 1. End caps 2 are fitted onto both ends of the housing 1. An air inlet 3 and an air outlet 4 are sequentially installed on the outside of the two sets of end caps 2. The air inlet 3 and the air outlet 4 guide and discharge the gas. A rotating shaft 5 is installed in the middle of the end caps 2. A turbine 6 is fitted onto the outside of the rotating shaft 5 at equal intervals. When the turbine 6 rotates, it compresses the gas. A guide plate 7 is fitted onto the outside of the turbine 6. An arc-shaped guide plate 8 is fitted onto the rear end of the guide plate 7. The guide plate 7 and the arc-shaped guide plate 8 are fitted onto the outside of the turbine 6. The guide plate 7 and the arc-shaped guide plate 8 guide the gas transmission. A connecting plate 9 is installed on the side of the guide plate 7 and the arc-shaped guide plate 8. An air outlet pipe 11 is obliquely fixedly connected to the rear end of the arc-shaped guide plate 8.

[0024] Please see Figure 1The outer casing 1, end cap 2, and air inlet 3 form a sealed box. An air inlet pipe is connected to the outside of the air inlet 3, and a compressed gas collection box is connected to the outside of the air outlet 4. After the turbine is installed inside the outer casing 1, end caps 2 are installed at both ends of the outer casing 1. The end caps 2 seal the inside of the outer casing 1 to prevent gas leakage. The air inlet 3 and air outlet 4 are installed on the outside of the end caps 2. The air inlet 3 drives the gas into the inside of the outer casing 1. The turbine 6 inside the outer casing 1 performs centrifugal compression on the gas, and the compressed gas is discharged through the air outlet 4. At the same time, the compressed gas produced is collected through the compressed gas collection box.

[0025] Please see Figure 2 The rotating shaft 5 passes through the interior of the end cover 2, and a sealing assembly is provided at the connection between the rotating shaft 5 and the end cover 2. A motor is installed on the outside of a set of end covers 2. The rotating shaft 5 passes through the interior of the end cover 2, and a turbine 6 is sleeved on the outside of the rotating shaft 5. When the motor is started, the motor drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the turbine 6 to rotate to provide power, ensuring that the turbine 6 provides power when it rotates.

[0026] Please see Figure 5 The inner side of the outer shell 1 is provided with a sliding groove. A limiting post 10 is fixedly installed on one side of the connecting plate 9. The slider and the limiting post 10 installed on the outside of the connecting plate 9 are both sleeved inside the sliding groove. When the equipment is installed, a guide plate 7 and an arc-shaped guide plate 8 are sleeved on the outside of the turbine 6. After the turbine 6 is installed inside the outer shell 1, the connecting plate 9 installed on the side of the guide plate 7 and the arc-shaped guide plate 8 slides into the sliding groove opened inside the outer shell 1. According to the different distances between the two sets of turbines 6, a limiting post 10 is installed between the two sets of connecting plates 9. The limiting post 10 squeezes and limits the position between the two sets of connecting plates 9 to ensure that the guide plate 7 and the arc-shaped guide plate 8 maintain tightness when spliced ​​on the outside of the turbine 6 and facilitate assembly.

[0027] Please see Figure 6 The arc-shaped guide plate 8 is circular and is sleeved on the side of the turbine 6. The guide plate 7 is sleeved on the front end of the turbine 6. Because the arc-shaped guide plate 8 is circular and the guide plate 7 is located at the front end of the turbine 6, the turbine 6 generates centrifugal force when it rotates. After the gas is injected into the outside of the turbine 6 through the front end of the guide plate 7, it is compressed inside the arc-shaped guide plate 8. After the pressurized gas flows inside the arc-shaped guide plate 8, it can be discharged through the exhaust pipe 11.

[0028] Please see Figure 6The arc-shaped guide plate 8 extends to the rear end of the turbine 6. The rear end of the turbine 6 is fixedly connected to the limit buckle 13. The limit buckle 13 is sleeved and installed inside the arc-shaped guide plate 8. When the arc-shaped guide plate 8 is sleeved outside the turbine 6, the limit buckle 13 is engaged inside the arc-shaped guide plate 8. That is, the limit buckle 13 limits the rotation trajectory of the arc-shaped guide plate 8 to ensure the stability of the arc-shaped guide plate 8 when it rotates.

[0029] Please see Figure 2 A protective plate 12 is fixedly connected to the outside of the guide plate 7. The protective plate 12 is sleeved and installed on the outside of the arc-shaped guide plate 8. The exhaust pipe 11 installed at the rear end of a set of turbines 6 is located at the front end of another set of guide plates 7. The front end of the guide plate 7 is provided with an air inlet. The protective plate 12 installed at the front end of the guide plate 7 is sleeved on the rear end of another set of arc-shaped guide plates 8. After the turbine 6 starts and generates centrifugal gas, it is delivered to the inside of the arc-shaped guide plate 8. The centrifugal force drives the gas to be compressed, and the compressed gas is delivered to the rear end of the turbine 6 through the exhaust pipe 11. At the same time, it is limited by the protective plate 12 to ensure that when the other set of guide plates 7 collects and compresses again, the gas flow is improved.

[0030] Working principle: In use, the rotating shaft 5 is installed inside the housing 1, and the turbines 6 are sequentially sleeved on the outside of the rotating shaft 5. During the process of the turbines 6 being sleeved on the outside of the rotating shaft 5, guide plates 7 and arc-shaped guide plates 8 are sleeved and installed on the outside of the turbines 6. The guide plates 7 and arc-shaped guide plates 8 are covered and installed on the outside of the turbines 6, and the connecting plates 9 installed on the outside of the guide plates 7 and arc-shaped guide plates 8 are engaged with the inside of the sliding groove opened in the housing 1. The limiting post 10 is adjusted according to the different spacing of each set of turbines 6 to ensure that the guide plates 7 and arc-shaped guide plates 8 are positioned outside the turbines 6. The casting is positioned and the end caps 2 are installed at both ends of the outer shell 1 for sealing. The rotating shaft 5 is started, and the rotating shaft 5 drives the turbine 6 to rotate. The rotating turbine 6 drives the gas to be absorbed. The absorbed gas is thrown outward under centrifugal force, and the gas brushed out is centrifugally compressed inside the arc-shaped guide plate 8. The compressed gas is transported to the inside of the protective plate 12 through the outlet pipe 11. It is then guided by the protective plate 12 to the outside of another set of turbines 6 for compression again. At the same time, the compressed gas is discharged through the outlet 4, thus realizing the preparation of compressed gas.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
