Description

Technical Field

[0001] The invention relates to the technical field of screw air compressors, in particular to a high-efficiency and energy-saving screw air compressor. Background Art

[0002] The screw air compressor uses a high-efficiency pulley drive to drive the main unit to rotate and compress the air. The compressed air in the main unit is cooled by oil injection. The air and oil mixed gas discharged from the main unit is separated through coarse and fine separation to separate the oil in the compressed air, and finally obtain clean compressed air. The screw air compressor is a kind of equipment widely used in industrial production. Its working principle and maintenance are the key to ensure the efficient operation of the equipment.

[0003] When currently used, existing screw air compressors usually have an air filter installed at the air inlet of the screw air compressor to prevent dust in the air from entering the interior of the air compressor. However, existing air filtration usually only filters the air through the filter element. However, since existing air filters usually have only one air inlet hole, there will be a situation where the area of ​​the filter element near the air inlet hole is more dusty, while other areas of the filter element are less dusty. (Since the operation of the air compressor creates a negative pressure state inside the air filter, most of the air entering the filter will quickly pass through the area of ​​the filter element near the air inlet hole and then enter the air compressor through the air outlet hole of the filter, resulting in more dust in the area of ​​the filter element near the air inlet hole). This leads to low overall filter element utilization rate. Moreover, since the position of the air inlet hole remains unchanged, the amount of air passing through the area of ​​the filter element near the air inlet hole per unit time will be reduced, resulting in reduced air compression efficiency of the air compressor. At this time, the air compressor requires more power to pump the gas, which increases the energy consumption of the screw air compressor and fails to achieve the purpose of energy saving.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-9 In an embodiment of the present invention, a high-efficiency and energy-saving screw air compressor includes a screw air compressor body 1. A filter mechanism 2 for filtering air is detachably connected to an air inlet of a head of the screw air compressor body 1. The filter mechanism 2 includes a mounting cylinder 21, a filter element 22, a tray assembly 23, a fixing assembly 24, a cleaning assembly 25, a driving member 26, and a collecting assembly 27. The mounting cylinder 21 is detachably connected to the air inlet of the head of the screw air compressor body 1. A plurality of air inlet pipes are fixed on the outer wall of the mounting cylinder 21 at equal angles in an annular manner. The interior of the mounting cylinder 21 is detachably connected to a filter element 22 for filtering the air entering the interior of the screw air compressor body 1. The inner bottom of the mounting cylinder 21 is provided with a tray assembly 23 for supporting the filter element 22. The inner top of the mounting cylinder 21 is provided with a fixing assembly 24 for fixing the mounting cylinder 21 to the top surface of the tray assembly 23. A cleaning assembly 25 for cleaning dust adsorbed on the surface of the mounting cylinder 21 is provided between the mounting cylinder 21 and the filter element 22. A driving member 26 for providing power to the cleaning assembly 25 and driving the filter element 22 to rotate inside the mounting cylinder 21 is provided in the air inlet pipe. The bottom end of the mounting cylinder 21 is detachably connected to a collecting assembly 27 for collecting dust cleaned by the filter element 22 by the cleaning assembly 25.

[0020] Specifically, first, a certain amount of engine oil is poured into the interior of the collecting assembly 27, and the collecting assembly 27 is installed at the bottom of the installation cylinder 21. Then, the fixing assembly 24 is taken out from the interior of the installation cylinder 21, and the filter element 22 is placed in it, so that the filter element 22 is snapped into the tray assembly 23. Then, the fixing assembly 24 is installed in the interior of the installation cylinder 21, and the top of the filter element 22 is snapped into the fixing assembly 24. At this time, the installation of the filter element 22 is completed. Then, the installation cylinder 21 is installed at the air inlet of the head of the screw air compressor body 1, so that the interior of the installation cylinder 21 is connected with the interior of the head. When the screw air compressor body 1 is started, the two screws in the head rotate to form a negative pressure in the interior of the installation cylinder 21. The negative pressure state in the installation cylinder 21 can allow external air to enter the interior of the installation cylinder 21 through multiple air intake pipes. Since a driving member 26 is provided in the air intake pipe, the air entering the installation cylinder 21 through the air intake pipe will generate wind to drive the driving member 26 at the corresponding position to rotate, and the rotation The driving member 26 can make the cleaning assembly 25 rotate, and the rotating cleaning assembly 25 drives the tray assembly 23 to rotate. Since the filter element 22 is stuck between the tray assembly 23 and the fixing assembly 24, the rotating tray assembly 23 can drive the filter element 22 to rotate inside the mounting cylinder 21. The rotating filter element 22 can increase the contact area with the air, and the rotating filter element 22 can make the air in the mounting cylinder 21 more evenly distributed, avoiding the air from concentrating through a certain part of the filter element 22. Therefore, it can prevent the dust adsorbed on a certain area of ​​the filter element 22 from being thicker while the dust in other areas is thinner, making the utilization rate of the filter element 22 higher, thereby improving the filtering effect of the filter element 22 and reducing the local overload of the filter element 22. In addition, the rotating cleaning assembly 25 can clean the dust adsorbed on the surface of the filter element 22 to avoid the dust from blocking the pores of the filter element 22, so that the resistance of air penetrating the filter element 22 is reduced, thereby reducing energy consumption and achieving the purpose of energy saving.

[0021] Example 1

[0022] like Figure 3 、 Figure 4 and Figure 7 As shown, in this embodiment, the top end of the inner wall of the mounting cylinder 21 is rotatably connected to a swivel 211, and the cleaning assembly 25 includes an annular brush 251 sliding between the mounting cylinder 21 and the filter element 22, and the outer wall of the annular brush 251 is fixedly connected to two symmetrical connecting blocks 252, and the bottom surface of the swivel 211 is rotatably connected to two symmetrical reciprocating screws 253 that penetrate and screw with the connecting blocks 252 at corresponding positions, and the top end of the inner wall of the mounting cylinder 21 is fixedly connected to the ring gear 212 below the ring gear 212, and the top end of the reciprocating screw 253 is fixedly connected to a spur gear 254 that meshes with the ring gear 212 for transmission.

[0023] In this embodiment, the rotation of the rotating ring 211 can make the two reciprocating screws 253 drive the annular brush 251 to rotate along the central axis of the rotating ring 211, and the reciprocating screw 253 rotating along the axis of the rotating ring 211, under the meshing action of the spur gear 254 and the ring gear 212 at the corresponding position, makes the spur gear 254 drive the reciprocating screw 253 at the corresponding position to rotate. The two rotating reciprocating screws 253 can make the annular brush 251 reciprocate along the length direction of the reciprocating screw 253, so that the annular brush 251 can move back and forth up and down inside the mounting cylinder 21 while rotating. The up and down reciprocating movement of the annular brush 251 can scrape off the dust adsorbed on the surface of the filter element 22, and the rotation of the annular brush 251 can make the filter element 22 vibrate slightly, so that the dust on the surface of the filter element 22 is easier to fall off under the action of the annular brush 251.

[0024] Example 2

[0025] like Figure 8 As shown, in this embodiment, the top surface of the rotating ring 211 is fixedly connected with a plurality of latch teeth at equal angles in an annular shape, and the inner wall of the mounting tube 21 is fixedly connected with a fixing ring 213 at a position corresponding to the air inlet pipe through a connecting frame. The driving member 26 includes a rotating shaft 261 that rotates through the fixing ring 213 at the corresponding position, and the outer wall of the rotating shaft 261 is fixedly connected with a plurality of groups of fan blades 262 at equal intervals, and each group of fan blades 262 is distributed in an annular shape at equal angles. One end of the rotating shaft 261 is fixedly connected with a bevel gear 263 that meshes with the latch teeth.

[0026] In this embodiment, the airflow generated when air enters the mounting cylinder 21 drives the multiple fan blades 262 and the rotating shaft 261 to rotate, and the rotating rotating shaft 261 can rotate the bevel gear 263 at the corresponding position. Since the bevel gear 263 is engaged with the teeth on the rotating ring 211, the multiple rotating bevel gears 263 can rotate the rotating ring 211, and the rotation of the rotating ring 211 can make the annular brush 251 move up and down while rotating, and the two reciprocating screws 253 can drive the tray assembly 23 and the filter element 22 to rotate when they rotate along the axis of the rotating ring 211. The device drives the multiple fan blades 262 and the rotating shaft 261 to rotate through the airflow generated when air enters the mounting cylinder 21, so that the rotating ring 211 drives the annular brush 251 to move and rotate, and drives the filter element 22 to rotate. No additional driving source is required for driving, which can reduce energy consumption.

[0027] Example 3

[0028] like Figure 5 and Figure 6As shown, in this embodiment, the tray assembly 23 includes a turntable 231, a rotating tube 232 is fixedly passed through the top surface of the turntable 231, a fixed tube 233 fixedly connected to the inner bottom surface of the mounting cylinder 21 is passed through the inner wall of the rotating tube 232, a plurality of extension rods 234 are fixedly connected at equal angles in a ring at the bottom end of the outer wall of the rotating tube 232, one end of the extension rod 234 is embedded in a ball that rotates and contacts the inner wall of the mounting cylinder 21, a rubber pad that is interference fit with the inner wall of the filter element 22 is fixedly connected to the top end of the outer wall of the rotating tube 232, wherein the outer walls of the two symmetrical extension rods 234 are fixedly connected to the fixed blocks 235 that are rotatably connected to the reciprocating screw rods 253 at the corresponding positions, and the inner wall top end of the mounting cylinder 21 is fixedly connected at equal angles. A plurality of limit frames 214 are fixedly connected at equal angles in the shape, and a magnet 1 is embedded and fixed on the inner bottom surface of the limit frame 214. The fixed component 24 includes a cylindrical block 241, and a connecting rod 242 is rotated through the bottom surface of the cylindrical block 241. The bottom end of the connecting rod 242 is fixedly connected to a rubber plug 243 that is interference fit with the inner wall of the filter element 22. The outer wall of the cylindrical block 241 is fixed with an extension plate 244 that is slidably connected to the limit frame 214 at the corresponding position at an annular equal angle, and a magnet 2 that is attracted to magnet 1 is embedded and fixed on the bottom surface of the extension plate 244. The outer wall of the connecting rod 242 is fixedly connected to a limit plate 245 that is fixedly connected to the top of the rubber plug 243. The diameter of the limit plate 245 is larger than the diameter of the rubber plug 243.

[0029] In this embodiment, by inserting the bottom end of the filter element 22 into the rotating tube 232, and the rubber pad fixed on the outside of the rotating tube 232 is interference-fitted with the inner wall of the filter element 22, and then by inserting a plurality of extension plates 244 fixed on the outer wall of the cylindrical block 241 into the limit frame 214 at the corresponding positions, and the rubber plug 243 is inserted into the top of the filter element 22 and interference-fitted, the sealing of the two ends of the filter element 22 can be increased, preventing air from entering the interior of the filter element 22 from both ends of the filter element 22 and then entering the head of the screw air compressor body 1 until the magnet The first magnet and the second magnet at the corresponding position attract each other, so that the cylindrical block 241 can fix the filter element 22 in the installation cylinder 21, which can prevent the filter element 22 from jumping during rotation. Since the connecting rod 242 and the cylindrical block 241 rotate through each other, and the rotating tube 232 and the fixed tube 233 rotate through each other, the filter element 22 fixed between the turntable 231 and the cylindrical block 241 rotates along the axis of the rotating ring 211 when the two reciprocating screws 253 rotate along the axis of the rotating ring 211, thereby avoiding the phenomenon that the dust in one area of ​​the filter element 22 is thicker and the dust in other areas is thinner.

[0030] Example 4

[0031] like Figure 4 、 Figure 5 and Figure 9As shown, in this embodiment, a plurality of through holes 215 are opened through the inner bottom surface of the mounting cylinder 21 at equal angles in an annular manner, a plurality of bristles 236 are fixedly connected to the bottom end of the outer wall of the extension rod 234, a magnet three is embedded and fixed to the bottom surface of the turntable 231, and the aggregate assembly 27 includes an annular shell 271 detachably connected to the mounting cylinder 21, an annular column 272 is fixedly connected to the inner bottom surface of the annular shell 271, a collar 273 is fixedly and rotatably connected to the top end of the outer wall of the annular column 272, a plurality of cross bars 274 are fixedly connected to the outer wall of the collar 273 at equal angles in an annular manner, a plurality of vertical bars 275 are fixedly connected to the bottom surface of the cross bars 274 at equal intervals, a magnet four is embedded and fixed to the top surface of the collar 273, and the bottom end of the mounting cylinder 21 is fixedly connected to a threaded column 216 that is screwed together with the annular shell 271.

[0032] In this embodiment, the rotation of the rotating tube 232 can drive the multiple extension rods 234 to rotate, so that the bristles 236 at the corresponding positions can rotate along the axis of the rotating tube 232, so that the annular brush 251 can sweep the dust cleaned from the surface of the filter element 22 into the annular shell 271. Since the bottom surface of the turntable 231 is embedded with a third magnet and the top surface of the collar 273 is embedded with a fourth magnet, the rotating turntable 231 can drive the collar 273 and the multiple horizontal rods 274 and the multiple vertical rods 275 to rotate (as to why the collar 273 rotates, because the bottom surface of the turntable 231 is embedded with a third magnet and the top surface of the collar 273 is embedded with a fourth magnet. This principle is similar to the principle of a magnetic coupling. This technology is existing technology, so it will not be elaborated on), so that the engine oil in the annular shell 271 can be stirred, so that the dust is mixed in the engine oil, and the dust is prevented from being adsorbed on the surface of the filter element 22 again.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
