DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-5 , an embodiment provided by the utility model:
[0023] An industrial carbon dioxide liquefaction compressor: comprising a compressor body 1, an output pipe 11 is fixedly connected to the surface of the compressor body 1, a connecting pipe 12 is installed on the surface of the output pipe 11, a noise reduction mechanism is arranged at the bottom of the compressor body 1, and the noise reduction mechanism comprises a sound insulation bottom plate 2, the sound insulation bottom plate 2 is fixedly connected to the bottom of the compressor body 1, a mounting plate 21 is contacted and connected to the surface of the sound insulation bottom plate 2, a sound insulation cover 22 is fixedly connected to the upper surface of the mounting plate 21, screws 23 are perforated and connected on the surfaces of the mounting plate 21 and the sound insulation bottom plate 2, a shock absorbing plate 24 is contacted and connected to the bottom of the sound insulation bottom plate 2, the screws 23 are threadedly connected to the shock absorbing plate 24, and the shock absorbing plate 2 4 is fixedly connected to the bottom of a shock absorbing spring 27, the bottom of the shock absorbing spring 27 is fixedly connected to a base 25, a damper 26 is fixedly connected to the surface of the base 25, the telescopic end of the damper 26 is fixedly connected to the bottom of the shock absorbing plate 24, and the shock absorbing plate 24 is slidably connected to the surface of the base 25. The noise reduction mechanism can be installed together with the sound insulation cover 22 during the installation of the compressor body 1, thereby reducing the number of installation steps. At the same time, a shock absorbing device is provided at the bottom of the compressor body 1. By adding shock absorption and sound insulation to the compressor body 1, the noise emitted by the compressor body 1 is greatly reduced, the working environment of the staff is improved, and the fault alarms of other machines are avoided from being covered.
[0024] Furthermore, a mounting mechanism is provided on the surface of the output pipe 11 and the connecting pipe 12, and the mounting mechanism includes a connecting ring 3. A group of connecting rings 3 are respectively installed on the surface of the output pipe 11 and the connecting pipe 12. A fixing block 31 is fixedly connected to the surface of the output pipe 11, and an elastic rod 32 is rotatably connected to the surface of the fixing block 31. A clamping block 33 is fixedly connected to the surface of the elastic rod 32, and a supporting block 34 is fixedly connected to the surface of the elastic rod 32. A limiting ring 35 is supportively connected to the surface of the supporting block 34. The connection between the output pipe 11 and the connecting pipe 12 is usually installed by using multiple groups of bolts, which is troublesome and laborious to install, and the bolts may loosen. The mounting mechanism is convenient and easy to use, and no bolts are used, so there will be no loosening of the bolts.
[0025] Furthermore, the bottom of the sound insulation cover 22 is open, and a circular hole is provided on the top of the sound insulation cover 22. The output pipe 11 passes through the circular hole of the sound insulation cover 22. The sound insulation cover 22 wraps the entire compressor body 1 on the sound insulation base plate 2. The sound insulation cover 22 is in contact with and connected to the top of the sound insulation base plate 2. The sound insulation base plate 2 cooperates with the sound insulation cover 22, which effectively reduces the noise of the compressor body 1 and blocks the noise of the compressor body 1 from propagating outward.
[0026] Furthermore, circular holes are provided on the surfaces of the mounting plate 21 and the sound insulation base plate 2, and a threaded groove is provided on the upper surface of the shock absorbing plate 24. The screws 23 penetrate the circular holes of the sound insulation base plate 2 and the mounting plate 21 at the same time, and the screws 23 are threadedly connected to the threaded grooves of the shock absorbing plate 24. The screws 23 now install the sound insulation cover 22 on the surface of the sound insulation base plate 2 through the mounting plate 21, and also install the sound insulation base plate 2 and the compressor body 1 on the surface of the shock absorbing plate 24, thereby reducing the steps for installing the sound insulation cover 22.
[0027] Furthermore, multiple groups of dampers 26 and shock-absorbing springs 27 are provided, and the dampers 26 and shock-absorbing springs 27 reduce the vibration of the shock-absorbing plate 24 on the base 25. The dampers 26 and shock-absorbing springs 27 dampen the compressor body 1 on the sound insulation bottom plate 2 through the shock-absorbing plate 24, thereby reducing the vibration of the compressor body 1 and thus reducing the noise generated by the compressor body 1.
[0028] Furthermore, a slot is provided on the surface of the connecting ring 3 , and the elastic rod 32 rotates on the surface of the output tube 11 through the fixing block 31 . The elastic rod 32 changes the specific positions of the clamping block 33 and the supporting block 34 on the output tube 11 by rotating.
[0029] Furthermore, the elastic rod 32 is in a "T" shape, and the elastic rod 32 is engaged and connected to the slot of the connecting ring 3. Under the elastic action of the elastic rod 32, the block 33 is firmly engaged and connected to the slot of the connecting ring 3. The block 33 firmly squeezes the connecting ring 3 on the connecting pipe 12 onto the connecting ring 3 on the output pipe 11, and the output pipe 11 and the connecting ring 3 on the connecting pipe 12 cannot rotate. Multiple groups of elastic rods 32 are arranged on the output pipe 11, and the limiting rings 35 are simultaneously sleeved on the outer surfaces of the multiple groups of elastic rods 32. The limiting rings 35 limit the rotation of the elastic rod 32 on the output pipe 11, thereby preventing the block 33 from detaching from the slot of the connecting ring 3.
[0030] Working principle: align the circular holes of the mounting plate 21 and the sound insulation base plate 2 with the circular grooves on the upper surface of the screw 23 at the same time, and pass the screw 23 through the circular holes of the sound insulation base plate 2 and the mounting plate 21 at the same time, so that the screw 23 is threadedly connected to the threaded groove of the shock absorbing plate 24. At this time, the sound insulation base plate 2 and the compressor body 1 are fixed on the shock absorbing plate 24, and the sound insulation cover 22 is fixed on the sound insulation cover 22 through the mounting plate 21. The damper 26 and the shock absorbing spring 27 reduce the vibration of the shock absorbing plate 24 on the base 25, so that the damper 26 and the shock absorbing spring 27 dampen the compressor body 1 on the sound insulation base plate 2 through the shock absorbing plate 24, and reduce the vibration of the compressor body 1, thereby reducing the noise generated by the compressor body 1. At the same time, the sound insulation cover 22 soundproofs the compressor body 1 on the sound insulation base plate 2, and effectively reduces the noise by sound insulation and shock absorption.
[0031] The elastic rod 32 rotates on the surface of the output tube 11 through the fixing block 31. Under the elastic support of the elastic rod 32, the clamping block 33 is engaged and connected to the clamping groove of the connecting ring 3. The clamping block 33 firmly locks the position of the connecting ring 3 on the output tube 11 and the connecting tube 12, thereby locking the position of the output tube 11 and the connecting tube 12. The base 25 is sleeved on the outer surface of the multiple groups of elastic rods 32, and the limiting ring 35 is supported by the supporting block 34. The limiting ring 35 limits the rotation of the elastic rod 32 on the output tube 11, ensures the position of the clamping block 33 on the clamping groove of the connecting ring 3, and completes the installation between the output tube 11 and the connecting tube 12.
