Description
Technical Field
[0001] This invention relates to the field of noise reduction compressor technology, specifically to a piston compressor that can reduce noise. Background Technology
[0002] A piston compressor is a mechanical device that uses the reciprocating motion of a piston within a cylinder to achieve the intake, compression, and discharge of gas. In industrial production, it provides stable compressed air for pneumatic tools and pneumatic control systems. In mining, it can be used to power pneumatic picks and rock drills. By compressing gas, the piston compressor can convert low-pressure gas into high-pressure gas, meeting the gas pressure and flow requirements in different scenarios, effectively improving the operating efficiency of related equipment, and ensuring the smooth progress of production operations. At the same time, its structure is relatively mature, its operational reliability is high, and it can adapt to a variety of complex working environments.
[0003] A noise-reducing piston compressor is a special type of piston compressor that reduces noise generated during operation by optimizing the structural design, adding sound insulation and noise reduction components, or improving the operating mechanism, based on the traditional piston compressor. It retains the core function of gas compression of the traditional piston compressor and can meet the compressed air needs of various fields. At the same time, it addresses the noise problem caused by mechanical vibration and airflow disturbance during the operation of the traditional piston compressor by setting sound insulation shells and vibration damping devices at key components, or by improving the transmission structure and cylinder operation mode, reducing the generation and propagation of noise. This allows it to reduce noise interference to the surrounding environment and operators while achieving gas compression, making it more suitable for scenarios with high requirements for noise control.
[0004] While traditional piston compressors can compress gas, they suffer from significant noise issues during operation. These compressors typically use a motor to drive a crankshaft, which in turn drives a connecting rod to propel the piston in a reciprocating motion within the cylinder, thus compressing and transporting the gas. While this process avoids insufficient gas pressure and unstable supply, ensuring basic equipment performance, the rigid connection between the motor, crankshaft, and connecting rod in the transmission structure easily generates severe mechanical vibrations at high speeds. These vibrations are transmitted through the machine body to the outside, creating vibration noise. This results in generally high noise levels during operation, causing noise pollution to the surrounding environment, affecting the hearing health of operators, and limiting the compressor's applicability.

A pulley 24 is fixedly connected to the output end of the main unit 23, cooperating with the transmission belt 27 to transmit power. A motor 25 is installed inside the bracket 8, serving as the core power source for equipment operation. The output end of the motor 25 is fixed... The device is connected to a second pulley 26, which can drive a first pulley 24 to rotate via a transmission belt 27.

To ensure operational stability, multiple cylinders 210 on the top of the main unit 23 are the execution components for compression operations. Driven by the power of the main unit 23, they realize the core compression function. The air filter mechanism 3 on the front side of the cylinder 210 purifies and filters the air entering the cylinder 210, removing impurities to prevent wear on the internal components of the cylinder 210, extend the service life of the equipment, and ensure compression efficiency. The emergency stop component 29 on the front side of the soundproof shell 21 provides safety protection. The warning light 291 in the middle of the front side of the upright plate 61 can display the equipment operating status in real time, making it easy for operators to keep track of the equipment status.

[0036] Reference Figure 2 , Figure 4 and Figure 7 The air filtration mechanism 3 includes multiple outer shells 31, which serve as mounting carriers and airflow channels for the filter components. The rear sides of each outer shell 31 are fixedly connected to the front side of a corresponding cylinder 210, enabling a stable connection between the outer shell 31 and the cylinder 210.

The front ends of the two sleeve columns 33 are rotatably connected to the top cover 36, which can cover the front edge of the filter plate 34. The outer walls of the two top covers 36 are rotatably connected to the positioning bolts 37, which can lock the relative position of the top cover 36 and the sleeve column 33. One end of the two positioning bolts 37 passes through the corresponding top cover 36 and sleeve column 33, which can firmly fix the filter plate 34 to the front side of the outer shell 1 31. The front side of the outer shell 1 31 is fixedly connected to the outer shell 2 38, which can form external protection for the internal filter structure and fixing components.
[0037] Specifically, multiple outer shells 31 are fixed to the rear side of the corresponding cylinder 210 and serve as the main channel for air to enter the cylinder 210, providing an installation carrier for the internal filter components. The two fixing posts 32 and the sleeve post 33 on the front side of the inner shell 31, together with the two circular grooves 35 on the filter plate 34, realize the precise positioning and sliding installation of the filter plate 34. The filter plate 34 can intercept impurities in the air and prevent them from entering the cylinder 210 and causing component wear. The top cover 36 at the front end of the sleeve post 33 and the positioning bolt 37 that penetrates the top cover 36 and the sleeve post 33 can firmly fix the filter plate 34 and prevent the filter plate 34 from shifting due to equipment vibration. The outer shell 38 on the front side of the outer shell 31 provides external protection for the filter plate 34 and the positioning bolt 37, which are vulnerable parts, reducing damage from external collisions. It also facilitates the loosening of the bolts and disassembly of the filter plate 34 for maintenance and replacement in the future.

An air outlet box 42 is fixedly connected to the front of the interior of the noise reduction box 41, guiding the noisy airflow inside the device into the box. A baffle 43 is fixedly connected to the rear of the interior of the noise reduction box 41, preventing direct airflow penetration and causing it to deflect. Guide plates 44 are fixedly connected to the upper and lower sides of the baffle 43, assisting in the formation of an orderly deflection path for the airflow. Guide plates 45 are fixedly connected to the upper and lower sides of the interior of the noise reduction box 41, enabling... In conjunction with the guide plate 44, the airflow guiding effect is enhanced. Two air outlet slots 46 are opened on the rear side of the noise reduction box 41, which can be used as the discharge channel for the treated airflow. Multiple rotating plates 47 are rotatably connected inside the two air outlet slots 46, which can adjust the opening and closing angle according to the airflow pressure and further block noise.

The left end of the mounting bolt 412 passes through the mounting plate 411 and is threaded to the right side of the air outlet box 42.
[0039] Specifically, the noise reduction box 41 is fixed to the rear side of the base 1 at the front, serving as the carrier of the entire noise reduction structure. It provides installation space for the internal noise reduction components and forms the basic cavity for noise isolation. The air outlet box 42 on the front side inside the noise reduction box 41 is the entry channel for the noisy airflow of the equipment, realizing the directional introduction of airflow. The baffle 43 on the rear side inside the noise reduction box 41, together with the guide plates 44 on its upper and lower sides, and the guide plates 45 on the upper and lower sides inside the noise reduction box 41, repeatedly deflect and guide the incoming airflow, so that the airflow energy is attenuated while the noise is reduced. Repeated reflections within the cavity cancel each other out. The two air outlet slots 46 on the rear side of the noise reduction box 41 are the discharge channels for the treated airflow. The multiple rotating plates 47 connected to the air outlet slots 46 can adjust their opening and closing angles according to the airflow pressure, ensuring smooth airflow discharge and further blocking noise from spreading outward, achieving a layered noise reduction effect. The filter screen 410 can be quickly installed by using the mounting bolts 412. The filter screen 410 adopts a porous honeycomb structure and attenuates the mid-to-high frequency noise inside the noise reduction box 41 through the frictional damping effect of its own pores.

The bottom of the mounting base 22 fits against the top of the top plate 9, which can increase the contact area and improve the load-bearing stability.
[0045] Specifically, the bottoms of multiple mounting slots 71 are rotatably connected to the top of mounting base 22, providing a suitable mounting channel and connection base for mounting bolts 72. Mounting bolts 72, which are opened on the left and right sides of the top of the top plate 9, are rotatably connected to the bottom of the mounting slots 71 that penetrate the mounting base 22. The mounting base 22 and the top plate 9 are detachably fixed through thread engagement, which not only ensures the firmness of the connection, but also facilitates disassembly and assembly operations during later equipment maintenance and repair. The bottom of the mounting base 22 and the top of the top plate 9 fit tightly together, increasing the contact area between the two and improving the load-bearing stability of the mounting base 22. This provides stability for the main unit 23 mounted on the top of the mounting base 22, preventing vibration or displacement of the main unit 23 during operation due to unstable installation.
[0046] Working Principle: The operation of this compression equipment is based on the base 1. The support 8 on the top of the base 1 extends upward and supports the top plate 9, forming the main frame of the equipment. The support mechanisms 5 on the front and rear sides of the support 8 further enhance the stability of the frame. The noise reduction mechanism 4 on the rear side of the base 1 reduces vibration noise during equipment operation at the source. The pressure mechanism 6 on the front side monitors the operating pressure parameters of the equipment in real time. The core compression operation of the equipment is completed by the compression mechanism 2. Its soundproof shell 21 is fixed to the top of the base 1, which not only forms a protective barrier for the internal components but also helps to reduce noise. The mounting seat 22 on the top of the top plate 9 is used to securely mount the main unit 23 through the mounting mechanism 7. The motor 25 inside the support 8 serves as the power source. The pulley 26 at its output end is connected to the main unit 23 via the transmission belt 27. The output pulley 24 is linked, and the flywheel 28 at the front end of the pulley 24 uses inertia to make the power transmission smoother and drive the main unit 23 to run. The multiple cylinders 210 on the top of the main unit 23 are compression execution components. The air filter mechanism 3 on the front side of the cylinder 210 purifies the intake air to prevent impurities from wearing the internal components of the cylinder 210 and to ensure compression efficiency. The emergency stop component 29 on the front side of the soundproof shell 21 undertakes the safety protection function. The warning light 291 on the front middle of the upright plate 61 displays the equipment operating status in real time. If the pressure mechanism 6 detects abnormal pressure or other faults, the operator can press the emergency switch 292 on the front left side of the upright plate 61 to quickly cut off the power and stop the motor 25. The power transmission of the transmission belt 27 is interrupted, and the main unit 23 and cylinder 210 stop working immediately.
[0047] Furthermore, the rear sides of multiple outer shells 31 are respectively fixed to the front sides of the corresponding cylinders 210, forming the main channel for air to enter the cylinders 210. The two fixing posts 32 on the front side inside the outer shell 31 extend forward to provide installation support for the filter structure. The sleeve post 33 on the front side of the fixing post 32 is the positioning core of the filter plate 34. When air enters, it must first pass through the filter plate 34 on the front side of the outer shell 31. The filter plate 34 is fitted onto the outer wall of the sleeve post 33 through two circular grooves 35 to achieve precise positioning. Dust and particulate impurities in the air will be intercepted by the filter plate 34, and the purified air enters the cylinder 210 through the outer shell 31. To prevent impurities from causing wear to the internal components of cylinder 210, the top cover 36 at the front end of sleeve 33 rotates and closes. With the positioning bolt 37 passing through the top cover 36 and sleeve 33, the filter plate 34 can be firmly fixed, preventing the filter plate 34 from shifting due to vibration during equipment operation. In addition, the outer shell 38 fixed to the front of outer shell 31 provides external protection for the filter plate 34 and the positioning bolt 37, which are vulnerable parts, reducing damage from external collisions. If the filter plate 34 needs to be replaced, simply loosen the positioning bolt 37 and open the top cover 36 to remove the filter plate 34 from the sleeve 33, achieving quick maintenance and ensuring that the filtration mechanism continues to function stably.
[0048] Finally, the noisy airflow generated by the operation of the equipment enters the noise reduction box 41 through the air outlet box 42 on the front side. After entering, the airflow directly contacts the baffle 43 fixed on the rear side of the noise reduction box 41. The baffle 43 vertically blocks the straight path of the airflow, forcing the airflow to split to the upper and lower sides. The split airflow passes through the guide plate 1 44. The guide plate 1 44 adapts to different airflow intensities by rotating the shaft 48, guiding the airflow along the preset trajectory and buffering the airflow impact force by rotation, further reducing noise. Then, the airflow contacts the guide plate 2 45 fixed on the upper and lower sides of the noise reduction box 41. The airflow, after multi-stage processing, is discharged through the two air outlet slots 46 opened on the rear side of the noise reduction box 41. Multiple rotating plates 47 rotatably connected in the air outlet slots 46 can rotate flexibly according to the airflow pressure, ensuring smooth exhaust and further weakening the remaining noise by blocking the rotating plates 47. By rotating the mounting bolt 3 412, the fixing and limiting of the mounting plate 411 on the air outlet box 42 is removed, and the filter screen 410 is pulled out for replacement, achieving the overall noise reduction effect.
