Description

Low-noise energy-saving oil-free screw blower
Technical Field
The invention relates to the technical field of oil-free screw blowers, in particular to a low-noise energy-saving oil-free screw blower.
Background
Compared with the traditional blower, the oil-free screw blower has the following performance advantages:
1. low energy consumption: the oil-free screw blower has basic adiabatic compression principle, total efficiency over 75%, and can save energy by 20-35% or more, higher exhaust pressure and lower pressure pulse than the Roots blower because the oil-free screw blower can compress.
2. Low noise: the pneumatic noise of the screw rotor is very small, the stable output eliminates the sudden release of the internal air, the wavy inlet and the air discharge port minimize the air flow fluctuation, and the fan noise is about 30-40 dB lower than that of the traditional Roots blower.
3. Intelligent: intelligent PLC control, remote control, multiple communication modes and convenient operation management.
The oil-free screw blower is generally designed on a base in an integrated manner, and from the structural volume of the equipment, the oil-free screw blower is designed in a layered manner to reduce the occupied space, and the blower structure is laid out by utilizing the space volume in the vertical direction. The assembly of the parts of the oil-free screw blower has professionality, and the parts are usually assembled into a complete whole for sale in practice by more oil circuit layout and sealing structures. Because of the integration of numerous structures, the whole weight is heavy, and a fork truck is usually adopted for transferring during transferring.
When the fork truck is inserted, the fork rod is connected with the base, and if the fork rod is matched with the hole on the base, the oilless screw blower is integrally forked, on one hand, if oil is remained on the fork rod, the lifting speed of the fork rod of the fork truck is slower, and the oilless screw blower is easily separated from the fork rod due to self weight of equipment, so that the oilless screw blower is damaged; on the other hand, only set up fixed hole on the base, reserve the size and be slightly small, lead to originally reserving the hole and lose originally use meaning, reserve the size and be slightly big, after the fork arm inserts, when fork truck shifts, the fork arm can make a round trip movement on the hole, has also increased fork truck and has shifted the risk that oilless screw air-blower leads to oilless screw air-blower drop.
The oil-free screw blower base has found limited significance in its use as a support only. The oil-free screw blower comprises an oil tank for lubricating the bearing and the synchronous gear, and after the oil tank is used for a long time, oil leakage easily occurs due to aging of the sealing ring, and a series of potential safety hazards are easily caused after leakage.
The oil-free screw blower base is typically a flat bottom surface, which, while saving manufacturing costs to some extent, places certain demands on the flatness of the field of use. If the base of the oil-free screw blower cannot be attached to the ground, when the oil-free screw blower operates, although a part of vibration is counteracted by the damping pad on the frame, the base still vibrates, and noise is easy to generate.
When the oil-free screw blower is used for air intake, although the air filter box is arranged, sundries mixed in the air are removed by utilizing the air filter core in the air filter box, the splicing part is usually locked by angle steel due to the fact that a plurality of air pipes are adopted for splicing. However, in practical application, the air pipe is easy to deform and lock in place, so that gaps are formed at the connecting positions, and further impurities enter from the gaps, and noise is easy to occur to the screw blower for a long time.

According to some embodiments of the invention, the invention provides a low-noise energy-saving oil-free screw blower, which comprises a motor 1, a coupler 2, an oil-free screw blower 3, a power system mounting frame 4, a silencer 5, an air inlet sound eliminating box 6, an air filtering box 7, an air inlet box group 8 and a base 9. The motor 1 is connected with the oil-free screw blower 3 through the coupling 2 in a transmission way, the motor 1 and the oil-free screw blower 3 are installed on the power system installation frame 4 through shock pads, the air filter box 7 is communicated with the air inlet sound-eliminating box 6, the air filter box 7 is communicated with the interior of the oil-free screw blower 3 through the air inlet box group 8, a plurality of sealing magnetic attraction pieces 10 are arranged in the air inlet box group 8, and the silencer 5 is communicated with the interior of the oil-free screw blower 3. The base 9 comprises a frame body 11, a collecting assembly 12, an adjusting assembly 13 and a connecting cavity 16. The upper surface of the frame body 11 is provided with a plurality of collecting holes 15, and the collecting holes 15 are communicated with the collecting assembly 12; the side of the frame body 11 is provided with a connecting cavity 16 in a penetrating way, and the connecting cavity 16 regulates and controls the width in the cavity through the regulating component 13. The sealing magnetic attraction piece 10 comprises a rubber gasket 17, a magnetic attraction ring 18, a sealing ring 19 and a magnetic attraction spiral inner through pipe 20, the magnetic attraction ring 18 is stuck on the inner surface of the rubber gasket 17, the inner surface of the rubber gasket 17 is fully covered with the magnetic attraction ring 18, the right side of the rubber gasket 17 is communicated with the magnetic attraction spiral inner through pipe 20, and the sealing ring 19 is nested on the outer surface of the rubber gasket 17. The round filter cotton is arranged at the tail end of the magnetic suction spiral inner through pipe 20, and the effect of tail end filtration is achieved before air enters the oil-free screw blower 3.
In the invention, two connecting cavities 16 are arranged on the base 9, the positions of the two connecting cavities 16 are deviated to one side of the central line of the whole base 9, and the positions of the connecting cavities 16 usually consider the positions of the centers of gravity of the motor 1 and the oil-free screw blower 3 arranged above the connecting cavities. While the dimensions of the attachment cavity 16 are generally compatible with the width dimensions of the forks of a conventional forklift, such as 20-30cm. Therefore, the width of the connecting cavity 16 is 30cm in combination with the weight of the whole machine equipment of the oil-free screw blower 3, and the forklift truck with corresponding ton amount can transfer the oil-free screw blower. An adjusting component 13 is arranged in the base 9 (at the outer side end of the connecting cavity 16) and is used for being attached to the side wall of the fork rod, meanwhile, a proper elastic spring 34 is selected, and the fork rod can be well limited left and right due to the matching of the friction plate 37.
The collecting assembly 12 is arranged at the bottom end of the oil tank 46, so that leaked oil can be collected, the phenomenon that the leaked oil spreads and disperses on the upper surface of the base 9 when the leaked oil is met is avoided, and potential safety hazards exist while cleaning is not easy.
When the traditional air inlet box group 8 is spliced, the sealing degree can be ensured by splicing and locking angle steel and locking a plurality of screws on one side. However, in practical application, it is found that once part of the screws are not locked, the gap is increased to a certain extent due to vibration generated by long-term operation of the oil-free screw blower 3, and the filtering effect of the air filter box 7 at the front end of air inlet through the air filter element 41 is failed. According to the invention, the glue gasket 17 is arranged at the splicing position of the air inlet box group 8, and the sealing ring 19 is also arranged at one side of the air inlet direction, so that the tightness is ensured.
