Description

Technical Field

[0001] This invention relates to the field of air compressor technology, and more specifically to a screw air compressor. Background Technology

[0002] A screw air compressor is a type of air compressor, which comes in single and twin screw types. The twin screw air compressor was invented more than a decade later than the single screw air compressor. In terms of design, the twin screw air compressor is more rational and advanced. The twin screw air compressor overcomes the shortcomings of the single screw air compressor, such as imbalance and easy bearing damage, and has the advantages of long service life, low noise, and greater energy saving.

[0003] The existing rotor rotates for a long time and compresses air, which causes its temperature to rise. The rotor is not easy to dissipate heat, resulting in low heat dissipation efficiency, which affects the use of the air compressor. At the same time, the air compressor lacks a filtration device, which allows a large amount of dust or fine sand to enter the air compressor, thereby damaging the rotor and affecting its service life. Summary of the Invention

[0004] To address these issues, the present invention provides a screw air compressor that solves the problems of rotor temperature rising due to prolonged rotation and air compression, poor rotor heat dissipation leading to low rotor heat dissipation efficiency, and impacting the use of the air compressor. Additionally, the lack of a filtration device allows a large amount of dust or fine grit to enter the air compressor, thereby damaging the rotor and affecting its service life.

[0016] 1. The blower blows air out and back-blowns the filter plate, blowing away the dust and grit adsorbed on the filter plate. At the same time, the vacuum cleaner starts and generates suction, which in turn generates suction on the dust hood. The dust and grit blown away are then adsorbed through the dust hood and transported into the vacuum cleaner through the second hose. By controlling the blower hood and dust hood to rotate 180 degrees in the forward direction and then 180 degrees in the reverse direction, the entire filter plate is cleaned. The brush bristles can sweep the surface of the filter plate, improving cleaning efficiency, avoiding rotor damage, and extending rotor life.

[0017] 2. The copper plate absorbs the heat inside the air compressor body and transfers it to the heat dissipation jacket. The air in the heat dissipation jacket absorbs the heat from the copper plate, thereby cooling the inside of the air compressor body, improving the air compressor's heat dissipation efficiency, and facilitating the use of the air compressor.

The transmission rod 26 drives the synchronous pulley 29 to rotate. The synchronous pulley 29 drives the synchronous belt 28 to rotate. The synchronous belt 28 drives the connecting shaft 35 to rotate. The connecting shaft 35 drives the blower hood 36 and the dust collection hood 14 to rotate, thereby controlling the blower hood 36 and the dust collection hood 14 to rotate 180 degrees in the forward direction and then 180 degrees in the reverse direction.

[0034] To achieve heat dissipation, this device employs the following technical solution: The heat dissipation component includes multiple copper plates 18, which are disposed inside the heat dissipation housing 2. The copper plates 18 penetrate the air compressor body 1 and extend into its interior. Multiple through slots are formed on one side of each copper plate 18. A second connecting pipe 5 is fixedly connected to one side of the heat dissipation housing 2. A cooler 3 is fixedly connected to one end of the second connecting pipe 5. A first connecting pipe 4 is fixedly connected to the output end of the cooler 3. A cover pipe 6 is fixedly connected to one end of the first connecting pipe 4. The cover pipe 6 is connected to the inlet of the air compressor body 1. The compressor body 1 is fixed by bolts. The copper plate 18 absorbs the heat inside the compressor body 1 and transfers it to the heat dissipation sleeve 2. The air drawn in from the intake cylinder 9 is input into the heat dissipation sleeve 2 through the third connecting pipe 7. The air is then transported through the heat dissipation sleeve 2 to the second connecting pipe 5, then to the cooler 3, then to the first connecting pipe 4, and finally to the cover pipe 6 and into the compressor body 1. The air in the heat dissipation sleeve 2 absorbs the heat from the copper plate 18, thereby cooling the inside of the compressor body 1. The cooler 3 then cools the air that has absorbed the heat.

[0035] In order to achieve the purpose of compressing air, the device adopts the following technical solution: the air compressor body 1 is provided with two screw rotors 19, which rotate and compress the incoming air;

[0036] In order to achieve the purpose of air intake, the device adopts the following technical solution: a connecting frame 31 is fixedly installed inside the air intake cylinder 9, a second motor 30 is fixedly installed on one side of the connecting frame 31, and a fan blade 32 is fixedly connected to the output end of the second motor 30. When the second motor 30 is started, the second motor 30 drives the fan blade 32 to rotate, and the fan blade 32 draws air into the air intake cylinder 9.

[0037] The usage process of this invention is as follows: When using this invention, the two screw rotors 19 rotate and compress the incoming air. The copper plate 18 absorbs the heat inside the air compressor body 1 and transfers it to the heat dissipation casing 2. The second motor 30 is started, and the second motor 30 drives the fan blades 32 to rotate. The fan blades 32 draw air into the air intake cylinder 9. The air is filtered by the filter plate 13. The air drawn into the air intake cylinder 9 is input into the heat dissipation casing 2 through the third connecting pipe 7. The air is then transported through the heat dissipation casing 2 to the second connecting pipe 5. The air is conveyed through pipe 5 to cooler 3, then through cooler 3 to first connecting pipe 4, then through first connecting pipe 4 to cover pipe 6 and into the air compressor body 1. A valve is installed at the connection between third connecting pipe 7 and first hose 8. A portion of the air conveyed in third connecting pipe 7 is conveyed through first hose 8 to vertical pipe 38, then through vertical pipe 38 to thin pipe 37, and then through thin pipe 37 to blown air through blown air hood 36. The blown air hood 36 blows out the air and back-flushes the filter plate 13, causing the dust and grit adsorbed on the filter plate 13 to be blown away, while simultaneously drawing... The vacuum cleaner 16 starts and generates suction, which in turn causes the dust hood 14 to generate suction. The dust and grit blown away by the dust hood 14 are then drawn in and transported into the vacuum cleaner 16 through the second hose 15. At the same time, the first motor 11 starts, which drives the drive shaft 24 to rotate. The drive shaft 24 drives the connecting plate 23 to rotate, which in turn drives the sliding shaft 22 to rotate. The sliding shaft 22 pushes the slide frame 21 to reciprocate, causing the slide frame 21 to drive the toothed plate 25 to reciprocate. The toothed plate 25 drives the gear 27 to rotate 180 degrees clockwise. After rotating 180 degrees in the forward direction, the transmission rod 26 rotates via gear 27. The transmission rod 26 rotates via synchronous pulley 29, which in turn rotates via synchronous belt 28. The synchronous belt 28 rotates via connecting shaft 35, which in turn rotates via blower hood 36 and dust suction hood 14. This controls the blower hood 36 and dust suction hood 14 to rotate 180 degrees in the forward direction and then 180 degrees in the reverse direction, thereby cleaning the entire filter plate 13. The brush bristles 34 can sweep the surface of the filter plate 13, improving cleaning efficiency.
