Description

Technical field:

[0001] The utility model relates to the technical field of air compressor equipment, and more specifically to a double-head silent box-type air compressor. Background technology:

[0002] Air compressors are the main body of air source devices and are widely used in industrial production. Oil-free scroll air compressors provide clean, oil-free compressed air and are a new type of air compressor with development prospects.

[0003] However, for the oil-free scroll air compressor, since it is oil-free compression, the temperature of the compressed air is very high, and it needs to be cooled when it is output. The existing cooling method is to connect a radiator to the output end of the oil-free scroll air compressor head and directly blow the radiator with a fan to cool the compressed air entering the radiator. However, the fan requires additional electricity, which increases energy consumption and the effect is not ideal.

[0004] Meanwhile, in the existing air compressor, the air outlet of the oil-free scroll air compressor head is directly connected to the air outlet cover, and the air is directly exhausted, which generates a lot of noise. Utility model content:

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a double-head silent box-type air compressor, which can blow the cooling air outlet of the oil-free scroll air compressor head directly toward the radiator, so that the compressed air in the radiator can be heat exchanged and cooled without the need to install an additional cooling fan, thereby reducing energy consumption. At the same time, a sound-absorbing cotton layer is installed in the air guide sleeve, which can reduce the noise of the gas discharged from the main head of the air compressor, thereby reducing noise and achieving a silent effect.

[0031] A vertical waist-shaped through hole 132 is formed in the middle of the side bending plate portion 131 of the oblique adjustment plate 13, and the vertical waist-shaped through hole 132 corresponds to the through hole at the rear of the corresponding side bending edge.

By tightening the second locking nut, the side bending edge is pressed against the corresponding side bending plate portion 131 and fixed by the rear fixing bolt and the second locking nut.

[0032] The left and right parts of the rear part of the oblique adjustment plate 13 are both formed with an adjustment waist-shaped through groove 133 extending forward and backward. The lower part of the vertical adjustment bolt 134 is fixed on the lower horizontal plate 11 or the upper horizontal plate 12.

[0034] A driving wheel 141 is fixed to the output shaft of the driving motor 14, the right end of the main shaft of the air compressor main head 100 extends out of the air compressor main head 100 and is fixed with a transmission wheel 101, and a transmission belt 150 is tensioned on the corresponding driving wheel 141 and the corresponding transmission wheel 101;

[0035] In this embodiment, the inclination angle of the oblique adjustment plate 13 can be adjusted by loosening the first locking nut and the second locking nut, and then rotating the upper locking nut 135 and the middle locking nut 136, so that the distance between the central axis of the output shaft of the driving motor 14 fixed on the oblique adjustment plate 13 and the central axis of the main shaft of the corresponding air compressor main head 100 can be changed, thereby ensuring the tension of the transmission belt 150 on the corresponding driving wheel 141 and the corresponding transmission wheel 101.

[0040] The sound-absorbing cotton layer 17 and the elastic sponge layer 162 can reduce and absorb the noise of the wind coming out of the heat dissipation outlet of the main head 100 of the air compressor, thereby achieving a silent effect.

[0041] Furthermore, two connecting frames 152 are fixed on the front wall of the vertical fixing plate 15, and the connecting frames 152 are fixed with radiators 20 (the radiator 20 adopts a flat tube radiator that can be directly purchased on the market, which will not be described in detail here), and there is a gap between the rear wall of the radiator 20 and the front wall of the vertical fixing plate 15, and the upper part of the air outlet hole 151 faces the lower rear wall of the corresponding radiator 20;

[0042] The ends of the compressed gas outlet pipes of the two air compressor main heads 100 are connected to the air inlets of the corresponding radiators 20, and the outlets of the two radiators 20 are connected to the same vertical pipe 21. The vertical pipe 21 is fixed at the front of the vertical fixing plate 15.

When the pressure detected by the pressure gauge installed on the connecting pipe of the external device connected to the end of the compressed gas main outlet pipe 22 is too high, it can be opened through the solenoid valve to relieve the pressure of the compressed air in the vertical pipe 21.

[0043] In this embodiment, vertical screws 3 are fixed to the top and bottom of the middle part of the rubber elastic block 1 and the upper rubber elastic block 2. The end of the upper vertical screw 3 extends out of the top surface of the corresponding lower horizontal plate 11 or the upper horizontal plate 12 and is inserted with a washer and a locking nut. The washer is clamped between the bottom surface of the corresponding locking nut and the top surface of the lower horizontal plate 11 or the upper horizontal plate 12. The end of the lower vertical screw 3 extends out of the bottom surface of the bottom plate of the main frame or the bottom surface of the transverse beam and is inserted with a lower washer and a lower locking nut. The lower washer is clamped between the top surface of the corresponding lower locking nut and the bottom surface of the bottom plate of the main frame or the bottom surface of the transverse beam.

[0044] A cooling fan 5 is fixed to the bottom surface of the rear part of the top plate of the main box body 10, and the air inlet of the cooling fan 5 faces the multiple air inlet holes formed on the top plate of the main box body 10.

[0045] In this embodiment, the cooling fan 5 is running, and external air can be brought into the main box body 10, which can cool the main head 100 of the air compressor in the main box body 10. At the same time, it can provide air intake for the air compression air inlet of the main head 100 of the air compressor, and at the same time, provide air intake for the air inlet of the volute in the main head 100 of the air compressor. The impeller in the volute (the impeller is fixed on the main shaft) rotates with the rotation of the main shaft, thereby realizing air suction, and the gas enters the volute from the air inlet on the side of the main shell of the volute close to the main head 100 of the air compressor, and then, along the air flow channel of the volute, the dynamic vortex disk and the static vortex disk of the main head 100 of the air compressor are heat exchanged and cooled, and then enter the air guide sleeve 16, and then blown to the corresponding radiator 2 0, this temperature is generally at 30 degrees. At the same time, the air compressed by the main head 100 of the air compressor enters the radiator 20. At this time, the temperature of the compressed gas entering the radiator 20 reaches about 180°. At this time, the gas blown out of the air guide sleeve 16 exchanges heat with the compressed gas in the radiator 20, so that the compressed gas is cooled. The cooled compressed gas finally enters the vertical pipe 21, and is finally discharged from the compressed gas main outlet pipe 22 to the subsequent connected equipment. Among them, the temperature of the compressed gas discharged from the compressed gas main outlet pipe 22 is generally about 50 to 60 degrees. The gas discharged through the volute in the main head 100 of the air compressor is cooled without the need to install additional cooling fans, so that it has a good energy-saving effect and at the same time, its cooling effect is guaranteed.
