Description

The static scroll is fixed on a frame, the dynamic scroll is driven by an eccentric shaft and is restricted by an anti-rotation mechanism, and rotates around the center of the base circle of the static scroll with a small radius. Air is sucked into the periphery of the static scroll through an air filter, and is gradually compressed in a plurality of crescent-shaped compression cavities formed by the meshing of the dynamic scroll and the static scroll, and is then continuously discharged through an axial hole of a central part of the static scroll In the actual use process, the scroll air compressor often filters the entering air through a filter screen at the air inlet. The scroll air compressor is in an environment with a lot of dust and lint, and the filter screen is often blocked, so that the scroll air compressor needs to be stopped for maintenance operation frequently, which inevitably interrupts the continuous operation of the scroll air compressor and affects the production process depending on the air supply.

The embodiments will be described below according to the overall structure of the present application.

[0018] Please refer to Figures 1-10The embodiment provides a scroll air compressor, which comprises a machine body 1, a connecting plate 4 fixedly connected to one side of the machine body 1, a sealing bin 5 fixedly connected to one end of the connecting plate 4, a through slot formed in each side of the sealing bin 5, an air inlet 2 arranged at the top of the machine body 1, and a three-way pipe 3 in communication with the two through slots and the air inlet 2; a second filter screen 26 arranged in the sealing bin 5 and used for filtering air entering the machine body 1; a backflush unit arranged in the sealing bin 5 and used for backflushing and cleaning the second filter screen 26; a cleaning mechanism arranged in the sealing bin 5 and used for gathering the backflushed air and more accurately acting on the surface of the second filter screen 26; and a gathering assembly arranged in the sealing bin 5 and used for gathering and cleaning fluff pollutants prone to winding and caking. The backflush unit comprises a first partition plate 9 fixedly connected to the inside of the sealing bin 5, a second partition plate 31 fixedly connected to each side of the first partition plate 9, and the first partition plate 9 and the two second partition plates 31, which divide the sealing bin 5 into a first air bin 13, a second air bin 14 and a third air bin 15. One end of the sealing bin 5 is provided with a first air inlet 17. The backflush unit further comprises an air inlet pipeline 11 fixedly connected to the inner side of the first partition plate 9, an air inlet end of the air inlet pipeline 11 in communication with the first air inlet 17, a second electromagnetic valve 12 arranged at each air outlet end of the air inlet pipeline 11, a transition bin 10 arranged in the second air bin 14 and the third air bin 15, a first air outlet 18 formed in the inner side of each transition bin 10, an air outlet end of the second electromagnetic valve 12 in communication with the first air outlet 18, and a first filter screen 16 arranged at the port of each transition bin 10. Two air inlet ends of the three-way pipe 3 are each provided with a first electromagnetic valve 8. When the machine body 1 works, air enters from the first air inlet 17. At this time, the right second electromagnetic valve 12 is opened, and the right first electromagnetic valve 8 is closed. The air enters the transition bin 10 from the first air outlet 18, then enters the first air bin 13 from the second filter screen 26, then enters the left transition bin 10 from the left second filter screen 26, and then is discharged from the first filter screen 16. At this time, the left first electromagnetic valve 8 is opened. The clean air can enter the air compressor from one of the air inlet tubes of the three-way pipe 3 through the air outlet and the air inlet 2, so that the quality of the compressed air output by the machine body 1 is stable, and the cleanliness requirement of the subsequent air using equipment is met. When the filter holes of the right second filter screen 26 are blocked, causing the air intake to decrease, the right second electromagnetic valve 12 and the left first electromagnetic valve 8 are closed, and the left second electromagnetic valve 12 and the right first electromagnetic valve 8 are opened, changing the air intake path, so that clean air blows against the right second filter screen 26 to blow off the dust on the surface of the second filter screen 26. The above operation can complete the filter screen cleaning without interrupting the operation of the body 1, ensuring that the production processes relying on the air compressor, such as pneumatic equipment driving and compressed air supply, continue to operate, avoiding production interruption, schedule delay or process stagnation caused by shutdown. When the filter screen is blocked, the air permeability of the filter screen can be quickly restored by switching the air intake path and reverse blowing cleaning, avoiding the decrease of air production efficiency of the air compressor caused by insufficient air intake, such as insufficient exhaust pressure and reduced air production rate, ensuring that the body 1 is always in a stable working state and maintaining its designed capacity, thereby improving the working efficiency of the body 1.

[0019] Please refer to Figures 3-9 The cleaning mechanism includes two sets of limiting seats 41 fixedly connected to one side of the two second partition plates 31, each set of limiting seats 41 has two limiting seats 41, the inner sides of the two limiting seats 41 are rotationally connected with one wind collecting plate 29 through a first rotating shaft, one side of the limiting seat 41 is fixedly connected with a second motor 49, the rotating directions of the two wind collecting plates 29 are oppositely arranged, the execution end of the second motor 49 penetrates to the inner side of the limiting seat 41 and is fixedly connected with the first rotating shaft, one side of the second partition plate 31 is provided with an auxiliary component for driving the second filter screen 26 to rotate, the auxiliary component includes one rotating plate 33 rotationally connected to the inner sides of the two second partition plates 31, the inner side of the rotating plate 33 is provided with an auxiliary groove 47, the inner side of the auxiliary groove 47 is rotationally connected with the second filter screen 26 through a second rotating shaft, one side of the second filter screen 26 is fixedly connected with a first auxiliary filter plate 36, the bottom of the first auxiliary filter plate 36 is fixedly connected with two auxiliary sealing plates 34, one side of the auxiliary sealing plate 34 is fixedly connected with the second filter screen 26, the two auxiliary sealing plates 34 are respectively attached to the inner edges of the auxiliary groove 47, the inner top of the auxiliary groove 47 is fixedly connected with a fixed plate 45, a plurality of second arc-shaped springs 46 are installed between the fixed plate 45 and the first auxiliary filter plate 36, one side of the first auxiliary filter plate 36 is fixedly connected with a second arc-shaped spherical rod 44 abutting against the wind collecting plate 29, one side of the second partition plate 31 is fixedly connected with an auxiliary connecting rod 42, one end of the auxiliary connecting rod 42 is fixedly connected with a limiting abutting plate 43 for limiting the second arc-shaped spherical rod 44, the inner side of the second partition plate 31 is provided with a driving component for driving the rotating plate 33 to rotate, the driving component includes one first motor 37 fixedly connected to one side of the two second partition plates 31, the execution end of the first motor 37 penetrates to the inner side of the second partition plate 31 and is fixedly connected with a straight gear 38, the straight gear 38 is rotationally connected to the inner side of the second partition plate 31 through a third rotating shaft, the outer wall of the rotating plate 33 is fixedly connected with a straight tooth ring 35 meshing with the straight gear 38; When the right second filter screen 26 is backflushed, the two right second motors 49 are started, and the output ends of the two second motors 49 are driven to rotate the two air collecting plates 29 in opposite directions by 90 degrees. At this time, the air collecting plates 29 block the path of the air in the right side into the transition bin 10, so that the air is collected between the two air collecting plates 29 through the inclined surfaces of the two air collecting plates 29, and then enters the transition bin 10 from the gap between the two air collecting plates 29. The air collecting plates 29 guide the airflow to be collected in a specific area between the two air collecting plates 29 through the inclined surfaces, so that the airflow is no longer dispersed into the transition bin 10, but is concentrated to the second filter screen 26 that needs to be backflushed. This concentration allows the wind force to act more accurately on the surface of the filter screen, avoiding the dispersion of the airflow to cause insufficient blowing force in some areas, ensuring that the filter screen is backflushed with sufficient strength, and improving the comprehensiveness of cleaning. When the air collecting plates 29 are rotated by 90 degrees (i.e., the air collecting plates 29 are rotated to the inside of the transition bin 10 in the direction of the second partition plate 31), the air collecting plates 29 contact the two second arc-shaped spherical rods 44 during rotation, thereby driving the two second arc-shaped spherical rods 44 to drive the second filter screen 26 to rotate in the auxiliary groove 47 (the second filter screen 26 can be rotated in the direction of the arrow), so that the included angle between the second filter screen 26 and the rotating plate 33 is 30 degrees. After the filter screen is inclined by 30 degrees, the dust and impurities loosened by the airflow no longer hover or re-adsorb on the surface of the filter screen due to the vertical filter screen, but slide down the inclined filter screen surface under the action of gravity, directly leaving the filter screen area such as falling into the dust collecting structure at the bottom of the transition bin 10. This process reduces the problem of secondary attachment of impurities brought back to the filter screen by the reverse airflow, ensures that the surface of the cleaned filter screen is cleaner, and quickly restores the air permeability. When the air collecting plates 29 are backflushed, the first motor 37 is started to drive the straight gear 38 to rotate, and then the straight gear 38 drives the straight gear ring 35 to rotate, and the straight gear ring 35 drives the rotating plate 33 to rotate. At this time, the second filter screen 26 rotates in a circle, so that the incoming air can backflush every part of the second filter screen 26. The circular rotation of the filter screen allows the high-speed airflow collected by the air collecting plates 29 to act on each area of the filter screen in turn, avoiding the cleaning blind area caused by backflushing in a fixed position. Especially for large or irregular filter screens, the rotating process can ensure that the edge, corner and other areas prone to dust accumulation can be covered by the airflow, completely removing the impurities on the surface and in the pores of the filter screen, ensuring the comprehensiveness of cleaning, thereby preventing the filter screen from being blocked and improving the working efficiency of the machine body 1.

[0020] Please refer to Figures 3-5The gathering assembly comprises the inclined plates 19 fixedly connected inside the two transition warehouses 10 respectively, the baffle 27 fixedly connected on one side of the inclined plate 19, the baffle 27 arranged above the first auxiliary filter plate 36, the second auxiliary filter plate 39 mounted at the connection position of the baffle 27 and the inclined plate 19, the auxiliary plate 32 fixedly connected on one side of the inclined plate 19, the dust falling channel 20 fixedly connected on the back of the inclined plate 19, the discharging groove arranged on the inner side of the inclined plate 19, the feeding inlet of the dust falling channel 20 communicated with the discharging groove, the material guiding component arranged on one side of the dust falling channel 20, the material guiding component comprising the third auxiliary filter plate 40 fixedly connected inside the dust falling channel 20, the opening and closing plate 21 rotatably connected to the inner side of the dust falling channel 20 through the fourth rotating shaft, the connecting rod 22 fixedly connected on one side of the opening and closing plate 21, the first arc-shaped spherical rod 23 fixedly connected on one side of the connecting rod 22, one end of the first arc-shaped spherical rod 23 penetrating through the dust falling channel 20 and extending to the outside of the inclined plate 19, the plurality of trapezoidal blocks 30 fixedly connected on one side of the rotating plate 33 and abutting against the first arc-shaped spherical rod 23, the auxiliary circular plate 24 fixedly connected to the outer wall of the first arc-shaped spherical rod 23, the first arc-shaped spring 25 mounted between the auxiliary circular plate 24 and the dust falling channel 20, the dust collecting component arranged on the bottom of the sealing warehouse 5, the dust collecting component comprising the two sealing channels 6 fixedly connected to the bottom of the sealing warehouse 5, the two material collecting grooves 48 arranged on the bottom of the sealing warehouse 5, the plurality of dust boxes 7 arranged on the inner side of the sealing channel 6, and the size of each two dust boxes 7 matched with the size of the material collecting groove 48, the limiting sliding block 28 fixedly connected to each side of each dust box 7, and the matching groove matched with the limiting sliding block 28 arranged on the inner side of the sealing channel 6, and the limiting sliding block 28 slidably connected to the sealing channel 6 through the matching groove; When the second filter screen 26 is back-flushed, the back-flushed wind flows from the inclined surface of the inclined plate 19 through the second auxiliary filter plate 39, and then enters the inside of the machine body 1 from the three-way pipe 3. When the wind flows through the auxiliary plate 32, because the auxiliary plate 32 is reversely inclined, a part of the dust will fall from the inclined surface of the inclined plate 19 and the bottom of the transition warehouse 10. At this time, because the wind flows above the transition warehouse 10, the lint and dust at the bottom of the transition warehouse 10 will not be affected, so as to prevent the lint and dust from floating in the transition warehouse 10 and avoid incomplete cleaning caused by air flow disorder, thereby laying a foundation for subsequent operation; When the rotating plate 33 rotates, it drives the plurality of trapezoidal blocks 30 to rotate. When the trapezoidal block 30 abuts against the first arc-shaped spherical rod 23, the first arc-shaped spherical rod 23 moves from the lowest point of the trapezoidal block 30 to the highest point of the trapezoidal block 30, and the connecting rod 22 is pushed by the first arc-shaped spherical rod 23 to drive the opening and closing plate 21 to open. At this time, the wind changes the path from the inside of the inclined plate 19 to the third auxiliary filter plate 40, and then blows out from the outside of the transition bin 10. At this time, the lint and dust are blocked by the third auxiliary filter plate 40. When the first arc-shaped spherical rod 23 is separated from the trapezoidal block 30, the opening and closing plate 21 returns to the original position under the action of the first arc-shaped spring 25, the wind restores the original path, and knocks the third auxiliary filter plate 40 through the opening and closing plate 21, and then abuts against the next trapezoidal block 30, thereby forming reciprocating knocking on the third auxiliary filter plate 40. At this time, the dust and lint blocked by the third auxiliary filter plate 40 will fall from the dust falling channel 20 to the bottom of the transition bin 10, so that the third auxiliary filter plate 40 can be vibrated at high frequency by mechanical knocking, and the impurities attached to the surface can be directly stripped. It is especially suitable for cleaning lint pollutants that are easy to entangle and agglomerate. The opening and closing plate 21 repeatedly knocks the third auxiliary filter plate 40, ensures that the filter plate is always in a self-cleaning state, avoids the increase of wind resistance and the decrease of filtering efficiency caused by the accumulation of impurities, and greatly improves the continuity of the machine body 1 work. The falling dust is collected by the dust box 7. When the dust box 7 collects dust for a period of time, the worker pushes the leftmost dust box 7, and pushes out the rightmost dust box 7. The worker cleans the dust of the pushed-out dust box 7, and then pushes the cleaned dust box 7 from the left. Another dust box 7 is cleaned. Through the circulation and alternation of the plurality of dust boxes 7, two dust boxes 7 are always in working position, ensuring that dust is continuously collected without stopping for cleaning dust boxes 7, ensuring the continuous operation of the equipment such as the transition bin 10 and the filtering system, and not affecting the overall working condition of the air compressor.

[0021] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto.
