Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a containerized air compressor housing and a mobile screw air compressor. Background Technology

[0002] Air compressors are fundamental products of industrial modernization. The term "electrical and automation" often includes the meaning of "all-pneumatic." Air compressors provide air power and are the core equipment of pneumatic systems. They are the main body of electromechanical air supply devices. They are devices that convert the mechanical energy of a prime mover (usually an electric motor or diesel engine) into gas pressure energy and are compressed air pressure generating devices.

[0003] Traditional screw air compressors are installed in compressor rooms and used only after being connected to post-processing equipment, limiting their operation to indoor use. However, certain outdoor operations require mobile air compressors, or users may choose to rent air compressors due to space constraints or cost considerations. Therefore, the demand for mobile air compressors is increasing. For ease of transport and relocation, existing mobile air compressors are typically placed directly inside a shipping container, meaning the compressor and container are independent. While this allows for rapid transport and relocation, the lack of integration between the compressor and container results in issues such as relatively high noise and vibration, poor heat dissipation, and cumbersome daily maintenance.

[0004] The technical problem to be solved by this utility model is: how to solve the problems of relatively large noise and vibration, poor heat dissipation and troublesome daily maintenance of existing mobile air compressors. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a containerized casing for air compressors and a mobile screw air compressor, which has the characteristics of simple structure, good noise reduction and vibration reduction effect, and convenient maintenance.

[0006] The technical solution adopted by this utility model is as follows: a container-type chassis for an air compressor, including a chassis body, the inner wall of which is provided with sound insulation material, an end door at one end of the chassis body, an air inlet at the other end, a first side door and a second side door respectively provided on opposite sides of the chassis body, the first side door and the second side door being arranged opposite to each other, the end door being provided with a first door leaf hinged to the chassis body, the air inlet being provided with an air inlet cover, a plurality of air guide strips being spaced apart on the air inlet cover, two adjacent air guide strips forming an air inlet channel, the surface of the air guide strips being provided with sound insulation material, the first side door being provided with a second door leaf hinged to the chassis body, and the second side door being provided with a third door leaf hinged to the chassis body.

[0007] The containerized air compressor enclosure of this application directly installs the working components of the compressor inside the enclosure, that is, directly uses the container as the air compressor enclosure, which allows the compressor and the container to be integrated into one unit, which is conducive to making full use of the internal space of the enclosure; by setting sound insulation material on the inner wall of the enclosure and setting sound insulation components on the surface of the air guide strip, the transmission of noise and vibration can be effectively blocked, which is conducive to noise reduction and vibration reduction; by setting end doors, first side doors and second side doors, the enclosure has a larger opening space, which facilitates the installation and subsequent maintenance of the air compressor; by setting an air inlet at one end of the enclosure, a larger air intake ventilation area can be obtained, which is conducive to the heat dissipation of the air compressor.

[0008] In some embodiments, the air guide strip includes an air inlet section and an air outlet section. One end of the air inlet section is connected to the air inlet side of the air inlet hood, and the other end extends obliquely toward the air outlet side of the air inlet hood and is connected to the air outlet section. The other end of the air outlet section extends obliquely toward the air outlet side of the air inlet hood and is connected to the air outlet side of the air inlet hood.

[0009] By adopting the above technical solution, two adjacent air guides form a "V" or inverted "V" shaped air duct, which can reduce the wind noise when the external airflow flows into the chassis through the air duct, and at the same time block the internal noise from being transmitted to the outside of the chassis through the air duct, which is conducive to reducing noise.

[0010] In some implementations, the sound insulation element is disposed on one or both sides of the air guide strip, and the sound insulation element is detachably connected to the air guide strip.

[0011] Using the above technical solution, the sound insulation component can be detachably connected to the air guide strip through Velcro, magnetic attachment, adhesive, snap-fit, etc. After a long period of use, dust and other debris will inevitably adhere to the surface of the sound insulation component. The detachable connection makes it easy to replace the sound insulation component as needed in the future.

[0012] In some implementations, the first side door and the second side door are located at the end of the housing near the air inlet.

[0013] In some implementations, there are two first doors and two second doors, and both the two first doors and the two second doors are double doors.

[0014] By adopting the above technical solution and using a double-door design, all or part of the doors can be opened as needed, which is flexible and saves the space required to open all the doors.

[0015] In some implementations, there are three third doors, one of which is directly hinged to the housing, and the other two third doors are hinged to each other, with one of them being directly hinged to the housing.

[0016] By adopting the above technical solution and setting three third doors, the second side door has a larger opening space and a more flexible opening combination.

[0017] In some implementations, the first, second, and third door panels are all equipped with locking bars.

[0018] By adopting the above technical solution, the locking rod can lock the door when the first, second, and third door panels are closed, thus preventing the door panels from suddenly opening during transportation or use.

[0019] In some embodiments, an electrical control box and a hot air outlet are also provided on the side of the enclosure. The electrical control box is located on the side of the enclosure near the second side door, and the hot air outlet is located on the side of the enclosure near the first side door.

[0020] Using the above technical solution, the electrical control box is used to install electrical control components, so that the operation of the air compressor can be controlled without entering the machine box. The hot air outlet can facilitate the discharge of hot air from the cooler outside the machine box, avoiding heat concentration inside the machine box, which is conducive to the long-term stable operation of the air compressor.

[0021] In some implementations, the housing is also provided with an air pipe connector, which is located at the end of the housing near the air inlet.

[0022] By adopting the above technical solution and setting up an air pipe connector, it is easy to connect the air pipe inside the chassis to the air pipe outside the chassis.

[0023] A mobile screw air compressor includes a compressor main unit, an oil-gas separator, a cooler, and the aforementioned casing, wherein the compressor main unit, the oil-gas separator, and the cooler are all built into the casing.

[0024] By adopting the above technical solution, the working parts of the air compressor are arranged in an orderly manner inside the casing, so that the casing and each working part are integrated into an organic whole, thereby improving the mobility of the air compressor.

[0036] Please see Figures 1 to 4 A preferred embodiment of the present invention provides a containerized air compressor housing 100, comprising a housing 10, the inner wall of which is provided with sound insulation material, an end door at one end of the housing 10, and an air inlet at the other end, a first side door and a second side door respectively provided on opposite sides of the housing 10, the first side door and the second side door being arranged opposite to each other, the end door being provided with a first door leaf 20 hinged to the housing 10, the air inlet being provided with an air inlet hood 30, the air inlet hood 30 being provided with a plurality of air guide strips 31 spaced apart, two adjacent air guide strips 31 forming an air inlet duct 32, the surface of the air guide strips 31 being provided with sound insulation material 33, the first side door being provided with a second door leaf 40 hinged to the housing 10, and the second side door being provided with a third door leaf 50 hinged to the housing 10. The containerized enclosure 100 for air compressors in this application directly installs the working components of the compressor inside the enclosure, that is, directly uses the container as the enclosure for the air compressor, which allows the compressor and the container to be integrated into one unit, which is conducive to making full use of the internal space of the enclosure; by setting sound insulation material on the inner wall of the enclosure 10 and setting sound insulation components 33 on the surface of the air guide strip 31, the transmission of noise and vibration can be effectively blocked, which is conducive to noise reduction and vibration reduction; by setting end doors, a first side door and a second side door, the enclosure has a larger opening space, which facilitates the installation and subsequent maintenance of the air compressor; by setting an air inlet at one end of the enclosure, a larger air intake ventilation area can be obtained, which is conducive to the heat dissipation of the air compressor.

[0037] like Figure 4 As shown, the air guide 31 includes an air inlet section 311 and an air outlet section 312. One end of the air inlet section 311 is connected to the air inlet side of the air inlet hood 30, and the other end extends obliquely towards the air outlet side of the air inlet hood 30 and connects to the air outlet section 312. The other end of the air outlet section 312 extends obliquely towards the air outlet side of the air inlet hood 30 and connects to the air outlet side of the air inlet hood 30. Two adjacent air guides 31 form a "V" or inverted "V" shaped air duct, which can reduce the wind noise when external airflow flows into the chassis through the air duct, and at the same time block internal noise from being transmitted to the outside of the chassis through the air duct, which is beneficial for noise reduction.

[0038] Optionally, the sound insulation component 33 is disposed on one or both sides of the air guide strip 31, and the sound insulation component 33 is detachably connected to the air guide strip 31. The sound insulation component 33 can be detachably connected to the air guide strip 31 by means of Velcro, magnetic attachment, adhesive, snap-fit, etc. After prolonged use, dust and other debris will inevitably adhere to the surface of the sound insulation component 33. The detachable connection makes it convenient to replace the sound insulation component 33 as needed in the future.

[0039] Preferably, the sound insulation component 33 is sound insulation cotton.

[0040] In this embodiment, the first side door and the second side door are located at one end of the housing 10 near the air inlet.

[0041] like Figure 2 As shown, in this embodiment, there are two first door panels 20 and two second door panels 40, and both the two first door panels 20 and the two second door panels 40 are configured as double doors. Using double doors allows for opening all or part of the doors as needed, providing flexibility and saving space required to fully open all doors.

[0042] like Figure 1 and Figure 3 As shown, there are three third door panels 50. One of the third door panels 50 is directly hinged to the housing 10, and the other two third door panels 50 are hinged to each other, with one of the other two being directly hinged to the housing 10. By setting three third door panels 50, the second side door has a larger opening space and a more flexible opening combination.

[0043] Preferably, the first door leaf 20, the second door leaf 40, and the third door leaf 50 are all equipped with locking rods 60. By setting the locking rods 60, the doors can be locked when the first door leaf 20, the second door leaf 40, and the third door leaf 50 are closed, preventing the doors from suddenly opening during transportation or use. During operation, the tightly closed doors also provide sound insulation and noise reduction.

[0044] Preferably, the side of the housing 10 is also provided with an electrical control box 70 and a hot air outlet 80.
