[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. Centrifugal compressors are very large applications.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-Figure 9 , a steam-water separation device for an air compressor shown in the figure includes a shell 1, a separation mechanism, a cleaning mechanism and a condensing mechanism. A delivery pipe 2 is fixedly connected to the upper end of the shell 1, and an exhaust pipe 3 is fixedly connected to the delivery pipe 2. The separation mechanism includes a filter ring 4 installed in the shell 1. A plurality of driving wheels 5 and guide wheels 6 are evenly arranged in the shell 1, which are used to bend and guide the filter ring 4 through the driving wheels 5 and the guide wheels 6, and enable the filter ring 4 to move in a circular manner while filtering. The cleaning mechanism includes a plurality of partition plates 7 fixedly installed in the shell 1, and a plurality of electric heating plates 8 are fixedly connected in the shell 1, which are used to pass a set amount of gas through the partition plate 7, and blow it back to the side of the filter ring 4 after being heated by the electric heating plates 8, so as to dry and clean the filter ring 4, and discharge the exhaust gas through the exhaust pipe 3. The condensing mechanism is installed in the shell 1, and is used to condense the gas filtered by the filter ring 4, further remove water vapor, and transport the gas to the delivery pipe 2 for output.

[0020] The separation mechanism also includes a bottom plate 9 fixedly mounted on the bottom of the shell 1, a top plate 10 is fixedly connected inside the shell 1, the upper and lower sides of the filter ring 4 are respectively fitted and slid with the top plate 10 and the bottom plate 9, the upper and lower ends of the guide wheel 6 are respectively rotatably connected with the top plate 10 and the bottom plate 9, the outer wall of the drive wheel 5 is rollingly fitted with the inner wall of the filter ring 4, the outer wall of the guide wheel 6 is rollingly fitted with the outer wall of the filter ring 4, and a conveying member for controlling the flow direction of gas delivery is provided inside the shell 1.

[0021] The conveying member includes a fixed ring 11 fixedly installed between the bottom plate 9 and the top plate 10, the outer wall of the fixed ring 11 is evenly fixedly connected with multiple groups of guide frames 12, the driving wheel 5 is rotatably connected to the inner wall of the guide frame 12, the side of the fixed ring 11 is evenly provided with multiple groups of ventilation holes 13 arranged toward the guide wheel 6, the side of the partition plate 7 is provided with multiple groups of connecting holes 14, the opening of the connecting hole 14 toward the electric heating plate 8 is smaller than the opening toward the guide wheel 6, and a driving member for driving the gas to flow is provided in the shell 1.

[0022] The driving member includes a first fixed pipe 16 fixedly mounted on the top plate 10, a plurality of delivery holes 17 are evenly arranged on the top plate 10 for delivering the gas around the guide wheel 6 to the first fixed pipe 16 and the shell 1, a plurality of air inlet holes 18 are evenly arranged on the bottom plate 9, and a fixing frame 19 fixedly connected to the top surface of the top plate 10 is fixedly connected to the bottom of the exhaust pipe 3, and a suction member is provided on the fixing frame 19 for driving the gas to be sucked and delivered.

[0023] The suction piece includes a driving motor 20 fixedly installed in a fixing frame 19. The model of the driving motor 20 is preferably YYHS-40. The output end of the driving motor 20 is coaxially fixedly connected with a driving shaft 21. The driving shaft 21 passes through the top plate 10 and is rotatably connected to the top plate 10. The outer wall of the driving shaft 21 is evenly and fixedly connected with multiple groups of driving leaves 22. The outer wall of the driving leaf 22 is slidably fitted with the side walls of the top plate 10, the bottom plate 9 and the fixing ring 11.

[0024] The cleaning mechanism also includes a rotating tube 23 coaxially fixedly installed on the upper end of the driving wheel 5, and the outer wall of the driving wheel 5 is evenly provided with multiple groups of side holes 24 connected to the rotating tube 23. A fixed box 25 is fixedly connected in the fixed frame 19, and the top end of the rotating tube 23 is rotatably connected to the fixed box 25. The rotating tube 23 is connected to the fixed box 25, and the top end of the fixed box 25 is connected to multiple groups of connecting tubes 26 connected to the exhaust pipe 3. A rotating part is provided on the driving shaft 21 for linking the driving wheel 5 to rotate when the driving shaft 21 rotates.

[0025] In this embodiment, the drive motor 20 is started to drive the drive shaft 21 to rotate, and the drive shaft 21 drives the drive blades 22 to rotate, so that the external gas is drawn into the fixed ring 11 through the air inlet 18, and then pushed to the surroundings by the drive blades 22, and output to the surrounding of the guide wheel 6 through the ventilation hole 13. At this time, the gas is filtered through the corresponding filter ring 4, and water vapor and dust are blocked on the side of the filter ring 4 close to the fixed ring 11. The filtered gas is transported to the area between the first fixed pipe 16 and the shell 1 above the top plate 10 through the delivery hole 17, and the subsequent condensation operation is performed through the condensation mechanism. The gas after condensation is output to the inside of the air compressor through the delivery pipe 2 for air compression.

[0026] During the rotation of the driving shaft 21, the rotating tube 23 is driven to rotate through the rotating member, and the rotating tube 23 drives the driving wheel 5 to roll against the inner wall of the filter ring 4, so that the filter ring 4 is guided and driven by the driving wheel 5 and the guide wheel 6, and rotates in a twisted shape. The advantage of the twisted shape is that the direction of gas transportation is fully separated. The gas in the filter ring 4 at the concave position is in a state of flowing toward the surrounding guide wheel 6 positions. At this time, the outer diameter of the filter ring 4 is small, so that the pores inside the filter ring 4 are larger on the side close to the fixed ring 11, and the gaps on the side close to the guide wheel 6 are smaller. During the transportation of the gas inside the pores, impurities and water vapor are gradually adsorbed by the filter ring 4, and the gas in the filter ring 4 at the convex position is in a state of flowing toward the inner driving wheel 5. At this time, the outer diameter of the filter ring 4 is larger than the inner diameter, which is more conducive to the reverse flow of the heated gas to the side of the driving wheel 5, and can flush out and take away the dust and water vapor in the pores during the flow, thereby improving the efficiency of self-cleaning.

[0027] The gas around the guide wheel 6 will flow into the electric heating plate 8 through the connecting holes 14 on the partition plates 7 on both sides and be heated. In the process of hot air flowing from the outer wall to the inner wall of the filter ring 4, a drying effect will be produced, and some dust attached to the inside will be blown out in the opposite direction, and output to the fixed box 25 through the side holes 24 and the rotating tube 23, and then output through the connecting pipe 26 and the exhaust pipe 3. Since the exhausted gas is not industrial exhaust gas, it only contains water vapor and a small amount of dust in the air. The exhaust pipe 3 can discharge the gas directly to the outside, and can also be connected to other collection equipment to collect and treat the exhaust gas.

[0028] By setting the driving blades 22, the external gas can be more powerfully drawn into the shell 1 and pushed to the designated position on the filter ring 4 for filtering and conveying operations, thereby improving the efficiency of gas conveying.

[0029] Example 2: Please refer to Figure 2-Figure 6 The present embodiment further illustrates the first embodiment. The condensing mechanism shown in the figure includes a condenser 27 fixedly mounted on a fixing frame 19, a second fixing pipe 28 is fixedly connected to the fixing frame 19, a plurality of condensing plates 29 are arranged between the outer wall of the second fixing pipe 28 and the shell 1, and the condensing plates 29 are alternately arranged with an inclination. A guide plate 30 is fixedly connected to the outer wall of the bottom end of the second fixing pipe 28, a collecting plate 31 is fixedly connected to the inner wall of the shell 1, the guide plate 30 and the collecting plate 31 have the same inclination direction, and a drainage member for discharging accumulated water is arranged between the guide plate 30 and the collecting plate 31.

[0030] The drainage component includes an inner gear ring 32 which is coaxially connected to the top end of the first fixed tube 16 and the bottom end of the second fixed tube 28 for rotation. A plurality of scrapers 33 are evenly and fixedly connected to the outer wall of the inner gear ring 32. The scrapers 33 are slidably fitted with the bottom surface of the guide plate 30 and the top surface of the collecting plate 31. A drainage pipe 34 is provided on the side of the shell 1. The rotating component is used to link the inner gear ring 32 to rotate during the rotation of the drive shaft 21.

[0031] In this embodiment, the gas flowing upward through the conveying hole 17 will bend and flow to the upper position through the gap between the guide plate 30 and the collecting plate 31, and the condensation plate 29 will be cooled by the condenser 27, so that the gas will fully contact the bottom of the condensation plate 29 when flowing between multiple groups of alternating and inclined condensation plates 29, and condensation water will be generated at the bottom of the condensation plate 29 and flow downward. Many small holes are provided between the condensation plate 29 and the second fixed pipe 28 and the shell 1, which can convey the condensation water flowing down from the upper side downward to the guide plate 30 and the collecting plate 31. The condensation water on the upper side of the guide plate 30 will also flow obliquely into the position between the collecting plate 31 and the shell 1, and be discharged through the drain pipe 34.

[0032] During the operation of the rotating part, the inner gear ring 32 will be driven to rotate slowly, so that the scraper 33 will continuously rotate between the guide plate 30 and the collecting plate 31, pushing the condensed water accumulated on the upper side of the collecting plate 31 to a position close to the drain pipe 34 for discharge, thereby reducing the accumulated water on the collecting plate 31. The condensed gas can be transported upward to the delivery pipe 2 for output.

[0033] Example 3: Please refer to Figure 5-Figure 7 This embodiment further illustrates the first embodiment. The rotating member shown in the figure includes a first gear 35 coaxially fixedly mounted on the outer wall of the driving shaft 21. A second gear 36 meshing with the first gear 35 is rotatably connected to the top plate 10. The second gear 36 is connected to the third gear 37 through a reducer transmission. A fourth gear 38 meshing with the third gear 37 is coaxially fixedly connected to the outer wall of any group of rotating tubes 23. Multiple groups of fourth gears 38 are all meshed with the inner gear ring 32.

[0034] In this embodiment, the drive shaft 21 drives the first gear 35 to rotate, and the first gear 35 drives the second gear 36 to rotate. After the reduction transmission of the reducer, the third gear 37 rotates slowly, the third gear 37 drives the fourth gear 38 to rotate, and the fourth gear 38 drives the inner gear ring 32 to rotate, so that the remaining fourth gears 38 are driven to rotate synchronously through the inner gear ring 32, so that multiple groups of rotating tubes 23 can rotate, and the rotation of the inner gear ring 32 will also cause the scraper 33 to rotate and wipe the water, and the structure operation is more stable and efficient.
