Description

Technical Field

[0001] The utility model relates to the technical field of scroll compressors, in particular to a scroll compressor stator with good mute effect. Background Art

[0002] The scroll compressor is a compressor with a compressible volume, which is composed of a fixed involute scroll and an eccentrically rotating and translating involute scroll. The scroll compressor is composed of two moving and stationary scrolls of double function equation profiles that mesh with each other.

[0003] The main function of the static disk in the current scroll compressor is to guide and control the flow of air, change the speed and direction of the air flow, and thus increase the pressure of the gas. However, during operation, due to the dynamic disk, a vortex motion is generated. The dynamic disk sucks the gas from the air inlet through rotation, and then increases the pressure of the gas through compression, and finally pushes the compressed gas out. During this process, the static disk will inevitably produce a lot of noise, and the current sound insulation effect of the static disk is relatively simple, which leads to a lot of noise during operation and affects the working environment.

[0022] refer to Figure 3 and Figure 4 As shown, a sound-absorbing plate 8 is arranged on the top of the inner cavity of the vortex stator 2, a sound-absorbing cotton 9 is arranged on the top of the sound-absorbing plate 8, a sealing ring 10 is arranged on the bottom of the vortex stator 2, the surface of the sealing ring 10 is movably connected to the inner cavity of the sealing groove 4, and the front and rear sides of the mounting shell 6 are fixedly connected with reinforcement blocks 11, and the opposite sides of the two reinforcement blocks 11 are fixedly connected to the vortex stator 2.

[0023] It should be noted that; through the arrangement of the sound-absorbing plate 8 and the sound-absorbing cotton 9 in the vortex stator 2, the noise generated by the vortex stator 2 can be effectively absorbed, helping to absorb noise and vibration energy and reduce noise propagation. The sealing ring 10 is in contact with the sealing groove 4 to improve the sealing between the vortex stator 2 and the vortex movable plate 3, thereby reducing noise transmission. The fixed connection between the reinforcement block 11 and the vortex stator 2 plays a role in reinforcing the mounting shell 6.

[0024] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the mounting member 7 includes a rotating rod 701, and the opposite sides of the two rotating rods 701 are both extended into the inner cavity of the mounting shell 6 and fixedly connected with a protrusion 702, and the front and rear sides of the two protrusions 702 are both provided with a movable plate 703, and the opposite sides of the two movable plates 703 are both fixedly connected with a spring group 704, and the opposite sides of the two spring groups 704 are both fixedly connected to the inner wall of the mounting shell 6, and the opposite sides of the two movable plates 703 are both fixedly connected with an insertion rod 705, and both sides of the movable plates 703 are fixedly connected with a slider 706, and both sides of the inner cavity of the mounting shell 6 are provided with grooves for matching with the slider 706, and the surface of the rotating rod 701 is provided with a rotating shaft 707, and one side of the rotating shaft 707 is fixedly connected to the mounting shell 6.

[0025] It should be noted that when the user needs to disassemble and maintain the vortex stator 2 and the vortex movable plate 3, the protrusion 702 is rotated by rotating the rotating rod 701. When the protrusion 702 rotates, it will press against the movable plates 703 on both sides. When the movable plates 703 move, it drives the slider 706 to move within the groove. At the same time, the movable plate 703 drives the plug rod 705 to disengage from the inner cavity of the plug plate 5, so that the vortex stator 2 can be disassembled, thereby eliminating the need to use a large number of bolts for installation and disassembly, thereby improving maintenance efficiency.

[0026] Working principle: Through the arrangement of the sound-absorbing plate 8 and the sound-absorbing cotton 9 in the vortex stator 2, the noise generated by the vortex stator 2 can be effectively absorbed, helping to absorb noise and vibration energy and reduce noise propagation. The sealing ring 10 contacts the sealing groove 4 to improve the sealing between the vortex stator 2 and the vortex movable plate 3, thereby reducing noise transmission. When the user needs to disassemble and maintain the vortex stator 2 and the vortex movable plate 3, the rotating rod 701 rotates in the rotating shaft 707 to rotate the protrusion 702. When the protrusion 702 rotates, it presses against the movable plates 703 on both sides. When the movable plates 703 move, it drives the slider 706 to move in the groove. At the same time, the movable plate 703 drives the insertion rod 705 to disengage from the inner cavity of the insertion plate 5, so that the vortex stator 2 can be disassembled, thereby eliminating the need to use a large number of bolts for installation and disassembly, thereby improving maintenance efficiency.
