Description

Technical Field

[0001] The utility model relates to the technical field of screw compressors, in particular to an exhaust end seat of a low-noise screw compressor. Background Art

[0002] A screw compressor is a positive displacement compressor with forced air transmission. It relies on the reasonable configuration of suction and exhaust ports on the shell to realize the basic operating process of suction, compression and exhaust of the compressor. When the exhaust pressure is greater than the end compression pressure, the air in the exhaust chamber will flow back to the compression chamber to complete the expansion and compression process. When the exhaust pressure is less than the end compression pressure, the gas needs to go through an expansion and pressure reduction process from the compression chamber to the exhaust chamber.

[0003] During the operation of the compressor, the meshing of the rotors and the periodic intake and exhaust of the compressor will generate noise. In the case of over-compression and under-compression, gas expansion and reflux will occur, which will aggravate the generation of noise. These noises are generally continuous and high-frequency, and therefore cause serious harm to personnel. Utility Model Content

[0004] The utility model aims to provide a low-noise exhaust end seat of a screw compressor to solve the technical problem of aggravated noise caused by gas expansion and backflow proposed in the above background technology.

[0025] See also Figure 1-2 As shown, an embodiment of the utility model is a low-noise screw compressor exhaust end seat, including a placement box 1, an exhaust end seat body 2 is arranged inside the placement box 1, an exhaust groove 3 is opened in the middle of the top of the exhaust end seat body 2, the exhaust groove 3 includes a stainless steel layer 4 and a metal sound-absorbing layer 5, the front of the stainless steel layer 4 is connected to the metal sound-absorbing layer 5 by a strong glue, a rotating rod 6 is fixedly connected in the exhaust groove 3, and a rotating silencer plate 7 is fixedly connected to the rotating rod 6 through the rotating rod 6, a threaded hole 8 is opened on the top of the exhaust end seat 2, and there are four threaded holes 8 in a square array with the top of the exhaust end seat body 2 as the center, a female rotor bearing hole 9 and a male rotor bearing hole 10 are opened on the top of the exhaust end seat body 2, and the female rotor bearing hole 9 and the male rotor bearing hole 10 are respectively located at the left and right ends of the exhaust groove 3.

[0026] The bottom end of the placement box 1 is fixedly connected with a spring 11, and there are four springs 11 arranged in a square array with the bottom end of the placement box 1 as the center, and the top ends of the four springs 11 are fixedly connected with a placement plate 12. The placement plate 12 serves the purpose of supporting and placing the exhaust end seat body 2, and the spring 11 can play a certain buffering role for the exhaust end seat body 2 during normal operation.

[0027] like Figure 3-4 As shown, the exhaust groove 3, the female rotor bearing hole 9 and the male rotor bearing hole 10 all pass through the placement plate 12 to the bottom end of the placement box 1, so that the exhaust groove 3, the female rotor bearing hole 9 and the male rotor bearing hole 10 on the exhaust end seat body 2 can work normally.

[0028] The threaded hole 8 penetrates to the bottom end of the placement plate 12, so that the exhaust end seat body 2 can be fixedly connected to the placement plate 12 through the cooperation of the threaded hole 8 and the bolt 15, thereby avoiding a large deviation of the exhaust end seat body 2 during operation.

[0029] A spring 2 13 is fixedly connected to the right side of the placement box 1. The spring 2 13 is symmetrically arranged with the right side of the placement box 1 as the center. The other ends of the two springs 13 are fixedly connected to a clamping plate 14, which can clamp and limit the exhaust end seat body 2.

[0030] There are four springs 13 and clamping plates 14 in a square array centered on the top of the placement box 1. The length of the clamping plates 14 at the upper and lower ends is smaller than the length of the clamping plates 14 at the left and right ends, so that the clamping plates 14 at the upper and lower ends and the clamping plates 14 at the left and right ends do not affect each other.

[0031] A bolt 15 is provided inside the threaded hole 8, and the bolt 15 is threadedly connected to the threaded hole 8. The length of the bolt 15 is slightly longer than the depth of the threaded hole 8. Through the threaded connection between the bolt 15 and the threaded hole 8, the exhaust end seat body 2 is fixedly connected to the placement plate 12 in the placement box 1. The threaded connection enables the exhaust end seat body 2 to be fixedly connected to the placement plate 12.

[0032] When the embodiment of the utility model is used, the exhaust end seat body 2 is placed inside the clamping plate 14 by compressing the spring 2 13, so that the exhaust end seat body 2 is placed inside the placement box 1 and on the top of the placement plate 12. The bolt 15 passes through the threaded hole 8, so that the bolt 15 is threadedly connected to the threaded hole 8, and the exhaust end seat body 2 is fixedly connected to the placement plate 12. The spring 1 11 and the spring 2 13 can effectively play a certain buffering role on the exhaust end seat body 2, thereby preventing the exhaust end seat body 2 from colliding with the placement box 1 and causing damage to the exhaust end seat body 2.

[0033] When the exhaust end seat body 2 is working normally, the exhaust end seat body 2 can perform exhaust operations through the exhaust groove 3. When the gas passes through the rotating silencer plate 7, the rotating silencer plate 7 is rotated by the rotating rod 6, which plays an effective silencing role. The metal sound-absorbing layer 5 also enables the gas to effectively silence and reduce noise when passing through the exhaust groove 3, providing a comfortable working environment for the user.
