Description

Technical Field

[0001] The present application relates to the field of air compressors, and in particular to a centrifugal air compressor device and a method of using the same. Background Art

[0002] An air compressor is a device used to compress gas. An air compressor is similar in construction to a water pump. Most air compressors are reciprocating piston, rotary vane or rotary screw.

[0003] In the related technology, a Chinese patent with authorization announcement number CN109209871B discloses a centrifugal air compressor, including an air compressor body, a placement table is provided on the air compressor body, a compression cabin and an air intake mechanism are respectively installed on both sides of the top of the placement table, an installation cavity is provided inside the compression cabin, a cooling channel is provided in the interlayer between the installation cavity and the compression cabin, a plurality of docking protrusions are fixedly installed on the inner walls on both sides of the installation cavity, a primary filter screen, a secondary filter screen and a non-woven fabric layer are installed in sequence between the inner walls on both sides of the air intake barrel, and the gas entering the compression cabin is filtered by the primary filter screen, the secondary filter screen and the non-woven fabric layer to ensure that the gas is clean.

[0004] The essence of filtering gas is to block impurities in the gas on the primary filter, secondary filter and non-woven fabric layer. After long-term use, more impurities will accumulate on the primary filter, secondary filter and non-woven fabric layer, which will affect the passage of gas. At the same time, the primary filter, secondary filter and non-woven fabric layer are located in the air inlet tank, which is not convenient for cleaning and replacement, thus affecting work efficiency, so it needs to be improved. Summary of the invention

[0005] In order to improve the problem that too many impurities accumulate on the primary filter, secondary filter and non-woven fabric layer, affecting the passage of gas and thus reducing work efficiency, the present application provides a centrifugal air compressor device and a method of using the same.

[0006] In the first aspect, the present application provides a centrifugal air compressor device adopts the following technical solution: A centrifugal air compressor device comprises a workbench, a compression cylinder and an air intake box, the compression cylinder being arranged on the workbench, a compression screw being arranged in the compression cylinder, a rotating rod being coaxially inserted in the compression cylinder, the rotating rod being driven to rotate by a rotating motor, a compression screw being sleeved on the rotating rod, a plurality of protrusions being arranged on the inner wall of the compression cylinder, an air duct being formed between the compression screw and the protrusions for gas circulation, the top of the air intake box being open, the bottom of the air intake box being connected to the compression cylinder through an air intake pipe, the bottom wall of the compression cylinder being connected to an exhaust pipe, a filter plate being arranged in the air intake box, the filter plate being used to block gas from entering into the air intake pipe, a replacement assembly being arranged on the air intake box, the replacement assembly being connected to the filter plate for replacing the filter plate.

[0007] By adopting the above technical solution, when in use, the outside gas enters the air intake box from the top opening of the air intake box, then passes through the filter plate to reach the air intake pipe, and enters the compression cylinder along the air intake pipe. At this time, the rotating motor is started to drive the rotating rod to rotate with the compression screw, and the compression screw cooperates with a number of protrusions to continuously squeeze the air, thereby compressing the air, and the compressed gas is discharged through the exhaust pipe.

[0008] During this process, the filter plate makes the gas entering the air intake box need to pass through the filter plate before reaching the air intake pipe, and the pores on the filter plate limit the passage of impurities carried by the air, so that the impurities in the air are left on the side of the filter plate away from the air intake pipe, which improves the cleanliness of the gas entering the air intake pipe, so that it is not easy for impurities to accumulate in the compression cylinder and affect the rotation of the compression screw, thereby improving the efficiency of compressed air. At the same time, when a lot of impurities accumulate on the filter plate and affect the passage of gas, start the replacement component and directly replace the filter plate in the air intake box, which increases the gas circulation rate and thus improves the efficiency of compressed gas.

[0009] Optionally, the replacement component includes a rotating rod and a rotating motor, the rotating rod is inserted into the air intake box, and the end of the rotating rod is rotatably connected to the inner wall of the air intake box, the rotating motor is arranged on the air intake box, and the output end of the rotating motor is coaxially fixed to one end of the rotating rod for driving the rotating rod to rotate, and a plurality of filter plates are provided on the rotating rod, and the plurality of filter plates are radially arranged with the rotating rod as the center, a clearance hole for the filter plate to move is opened on one side of the air intake box, and a closing mechanism for closing the clearance hole is provided on the air intake box.

[0010] By adopting the above technical solution, after long-term use, more impurities are likely to accumulate on the side of the filter plate away from the air inlet pipe, blocking the pores on the filter plate and affecting the rate at which gas passes through. At this time, the rotating motor is started to drive the rotating rod to rotate, causing the filter plate with accumulated impurities to flip out of the air inlet box from the clearance hole, while the adjacent filter plate is simultaneously flipped into the air inlet box from outside the air inlet box through the clearance hole, replacing the original filter plate, thereby realizing the replacement of the filter plate and making the circulation of gas less easily affected.

[0011] Optionally, the closing mechanism includes a driving assembly and a closing assembly, the driving assembly is disposed on the air intake box, the closing assembly is connected to the driving assembly, and the driving assembly is used to drive the closing assembly to move so as to close or open the clearance hole.

[0012] By adopting the above technical solution, when there is a filter plate in the air intake box horizontally arranged between the top opening of the air intake box and the air intake pipe, the driving assembly is started to drive the closing assembly to block the clearance hole, so that the clearance hole is in a closed state, that is, the only channel for gas to enter the air intake box is the top opening of the air intake box, ensuring that the gas reaching the air intake pipe is filtered by the filter plate.

[0013] Optionally, the closing assembly includes an upper closing plate and a lower closing plate, which are arranged up and down, and both the upper closing plate and the lower closing plate can be sleeved on the filter plate. When the upper closing plate abuts against the lower closing plate, they are used to close the clearance hole.

[0014] By adopting the above technical solution, when one of the filter plates on the rotating rod is horizontally mounted in the air intake box, two filter plates will be aligned with the upper closing plate and the lower closing plate respectively. At this time, the driving assembly is used to drive the upper closing plate and the lower closing plate to approach each other, so that the upper closing plate is sleeved on the corresponding filter plate, and the lower closing plate is also sleeved on the corresponding filter plate, until the upper closing plate and the lower closing plate are spliced ​​together, blocking the clearance hole, and realizing the closure of the clearance hole. The filter plate is inserted in the upper closing plate and the lower closing plate, and also plays a positioning role, so that the rotating rod cannot rotate, thereby improving the stability of the filter plate horizontally mounted in the air intake box in the air intake box.

[0015] Optionally, the driving assembly includes a V-belt, a transmission gear and two transmission racks. The V-belt is rotatably connected to the air intake box. Two driven wheels of the V-belt are coaxially fixed with driven gears. The transmission gear is rotatably connected to the air intake box. The transmission gear is meshed with one of the driven gears. The transmission rack is arranged in a vertical direction. The two transmission racks are respectively fixed on the upper closing plate and the lower closing plate. One of the transmission racks is meshed with the transmission gear, and the other transmission rack is meshed with the other driven gear.

[0016] By adopting the above technical solution, the triangular conveyor belt is driven to move, so that the two driven wheels drive the driven gears to rotate synchronously, and one of the driven gears drives the transmission gear to rotate, so that the rotation directions of the driven gear and the transmission gear are opposite. Since the two transmission racks are respectively meshed with the transmission gear and the driven gear, that is, the movement directions of the two transmission racks are opposite, the upper closing plate and the lower closing plate are moved closer to each other to close the clearance hole, or moved away from each other to open the clearance hole.

[0017] Optionally, an arc-shaped mesh plate is provided in the air intake box, and the arc-shaped mesh plate is located on a side of the filter plate close to the air intake pipe, and the arc-shaped mesh plate is arranged along the moving track of the filter plate.

[0018] By adopting the above technical solution, when the rotating rod drives the filter plate to move, the filter plate located in the air intake box is separated from the inner wall of the air intake box, so that the gas entering from the opening of the air intake box will reach the other side of the filter plate from the gap between the filter plate and the inner wall of the air intake box, and then the gas needs to pass through the arc mesh plate to reach the air intake pipe, so that the filter plate will be protected by the arc mesh plate during the replacement process, so that impurities in the gas still cannot directly reach the air intake pipe. During this process, there is no need to stop the air intake of the compression cylinder, that is, the work of compressing the air continues, thereby improving work efficiency.

[0019] Because the arc-shaped mesh plate is arranged along the moving track of the filter plate, when the filter plate is rotated and replaced, the adjacent filter plates will slide on the arc-shaped mesh plate, so that the arc-shaped mesh plate can be cleaned and then reach the position where the filter plate was originally located in the air intake box.

[0020] Optionally, a brush plate is connected to the upper closing plate via a connecting rod, and the brush plate can abut against a filter plate located outside the air intake box.

[0021] By adopting the above technical solution, when the filter plate is replaced, the upper closing plate moves downward, so that the connecting rod moves downward with the brush plate, and when the upper closing plate is spliced ​​with the lower closing plate, the brush plate abuts against the filter plate, wherein after the filter plate is rotated out of the air intake box, the side of the filter plate that originally faces upward in the air intake box will turn downward, so that the impurities accumulated on the filter plate can fall off. At the same time, the brush plate abuts against the filter plate, so that the brush on the brush plate penetrates the pores on the filter plate, which is convenient for pushing out the impurities and realizing the cleaning of the filter plate.

[0022] Optionally, a sleeve is provided on the connecting rod, and the sleeve is fixed to the brush plate. A coil spring is provided in the sleeve, and the coil spring is provided on the connecting rod. One end of the coil spring is fixed to the sleeve, and the other end is fixed to the connecting rod. A rotating assembly is provided on the air intake box, and the rotating assembly is connected to the sleeve. The rotating assembly is used to drive the sleeve to rotate.

[0023] By adopting the above technical solution, when the upper closing plate drives the brush plate to move downward, the rotating assembly drives the sleeve to rotate. At this time, the coil spring gradually reels. When the upper closing plate and the lower closing plate are spliced, the brush plate abuts against the filter plate outside the air intake box. At this time, the sleeve is separated from the rotating assembly, and the coil spring is released, driving the sleeve to reverse, thereby driving the brush plate to rotate and slide on the filter plate to achieve cleaning of the filter plate.

[0024] Optionally, the rotating assembly includes a moving block and a moving spring, a mounting rod is fixed on the air intake box, a mounting hole is provided on the mounting rod, the moving block is inserted in the mounting hole and can move in the mounting hole, the moving block is connected to the inner wall of the mounting hole through the moving spring, a guide surface is provided on the side of the moving block close to the brush plate, when the guide surface abuts against the sleeve, it is used to drive the moving block to be received in the mounting hole, a rotating groove is provided on the side wall of the sleeve, the moving block is inserted in the rotating groove and can move in the rotating groove to drive the sleeve to rotate.

[0025] By adopting the above technical solution, when the upper closing plate drives the brush plate to move downward, the moving block moves vertically relative to the sleeve. Since the position of the moving block is fixed, the moving block applies an oblique thrust to the inner wall of the rotating groove, thereby causing the moving block to move relatively in the rotating groove along the trajectory of the rotating groove, that is, the sleeve rotates around the connecting rod. When the brush plate moves to abut against the filter plate, the moving block moves relatively out of the top opening of the rotating groove, and the sleeve is reversed under the action of the coil spring.

[0026] When the filter plate needs to be replaced again, the upper closing plate drives the brush plate to move up. At this time, the end wall of the sleeve abuts against the guide surface on the moving block. The guide surface plays a guiding role, allowing the sleeve to slide relatively on the guide surface, so that the moving block squeezes the moving spring and is stored in the installation hole, which is convenient for the sleeve to pass through. When the clearance hole is fully opened, the height of the sleeve makes the moving block just align with the rotating groove. Under the elastic force of the moving spring, the moving block is inserted into the rotating groove. Repeat the above steps to realize the rotation and force storage when the sleeve moves down. After moving down to the right position, the sleeve is reset to complete the cleaning of the brush plate on the filter plate.

[0027] On the other hand, the present application provides a method for using a centrifugal air compressor device using the following technical solution: S1. The gas in the air intake box passes through the filter plate and enters the air intake pipe, and then the gas goes into the compression cylinder along the air intake pipe; S2, the compression screw rotates, so that the compression screw and the bump cooperate to continuously squeeze the gas, so that the other compressed gas flows in the air duct, and the compressed gas is discharged through the exhaust pipe; S3, using the driving assembly to drive the closing assembly to open, so that when the rotating rod rotates, the filter plate can be driven to enter and exit the air inlet box, thereby realizing the replacement of the filter plate; S4. After the filter plate is replaced, the driving assembly is used to drive the sealing assembly to reset to close the clearance hole.

[0028] In summary, the present application includes at least one of the following beneficial effects: 1. The filter plate makes the gas entering the air intake box need to pass through the filter plate before reaching the air intake pipe, and the pores on the filter plate limit the passage of impurities carried by the air, so that the impurities in the air are left on the side of the filter plate away from the air intake pipe, which improves the cleanliness of the gas entering the air intake pipe, so that it is not easy for impurities to accumulate in the compression cylinder and affect the rotation of the compression screw, thereby improving the efficiency of compressed air. At the same time, when a lot of impurities accumulate on the filter plate and affect the passage of gas, start the replacement component and directly replace the filter plate in the air intake box, which increases the gas circulation rate and thus improves the efficiency of compressed gas; 2. When the filter plate needs to be replaced, the upper closing plate drives the brush plate to move up. At this time, the end wall of the sleeve abuts against the guide surface on the moving block. The guide surface plays a guiding role, allowing the sleeve to slide relatively on the guide surface, so that the moving block squeezes the moving spring and is stored in the installation hole, which is convenient for the sleeve to pass through. Until the clearance hole is fully opened, the height of the sleeve makes the moving block just align with the rotating groove. Under the elastic force of the moving spring, the moving block is inserted into the rotating groove. After the filter plate is replaced, the upper closing plate drives the sleeve to move down, and the moving block moves relatively in the rotating groove, so that the sleeve can rotate and accumulate force when it moves down. After moving down to the right position, the moving block moves out of the rotating groove, and the sleeve is reset under the action of the coil spring, completing the cleaning of the brush plate on the filter plate.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-6 This application is described in further detail.

[0032] The present application embodiment discloses a centrifugal air compressor device. Figure 1 and Figure 2 The centrifugal air compressor device includes a workbench 10, a compression cylinder 90 and an air intake box 20. The compression cylinder 90 is arranged on the workbench 10. A compression screw 111 is provided in the compression cylinder 90. A rotating rod 110 is coaxially inserted in the compression cylinder 90. The rotating rod 110 is driven to rotate by a rotating motor 112. The compression screw 111 is sleeved on the rotating rod 110. A plurality of protrusions 91 are provided on the inner wall of the compression cylinder 90. An air duct is formed between the compression screw 111 and the protrusions 91 for gas circulation. The top of the air intake box 20 is open, and the bottom of the air intake box 20 is connected to the compression cylinder 90 through an air intake pipe 92. The bottom wall of the compression cylinder 90 is connected with an exhaust pipe 93.

[0033] When in use, external air enters the air intake box 20 from the top opening of the air intake box 20, then enters the air intake pipe 92, and enters the compression cylinder 90 along the air intake pipe 92. At this time, the rotating motor 112 is started to drive the rotating rod 110 to rotate with the compression screw 111. The compression screw 111 cooperates with a number of protrusions 91 to continuously squeeze the air, thereby compressing the air, and the compressed gas is discharged through the exhaust pipe 93.

[0034] Reference Figure 3 and Figure 4A clearance hole 21 is provided on one side of the air intake box 20, so that one side of the air intake box 20 is in an open state. A replacement assembly 40 is provided on the air intake box 20. The replacement assembly 40 includes a rotating rod 41 and a rotating motor 42. The rotating rod 41 is horizontally mounted in the clearance hole 21. The end of the rotating rod 41 is rotatably connected to the air intake box 20. The rotating motor 42 is installed on the air intake box 20 by bolts. The output end of the rotating motor 42 is coaxially fixed with one end of the rotating rod 41 to drive the rotating rod 41 to rotate. A plurality of filter plates 30 are installed on the rotating rod 41. The filter plates 30 are arranged along the length direction of the rotating rod 41. The plurality of filter plates 30 are arranged radially with the rotating rod 41 as the center. When the rotating rod 41 rotates, the filter plates 30 are driven to move, so that the filter plates 30 pass through the clearance hole 21 to enter and exit the air intake box 20.

[0035] The filter plate 30 can be inserted into the air intake box 20, and the circumferential side wall of the horizontally arranged filter plate 30 abuts against the inner wall of the air intake box 20, thereby dividing the air intake box 20 into two upper and lower areas, so that the gas entering the air intake box 20 from the top opening of the air intake box 20 needs to pass through the filter plate 30 to reach the air intake pipe 92 below, thereby filtering the gas. The pores on the filter plate 30 limit the passage of impurities entrained by the air, so that the impurities in the air are left on the side of the filter plate 30 away from the air intake pipe 92, thereby improving the cleanliness of the gas entering the air intake pipe 92, so that it is not easy for impurities to accumulate in the compression cylinder 90 and affect the rotation of the compression screw 111, thereby improving the efficiency of compressed air.

[0036] At the same time, when a large number of impurities are accumulated on the filter plate 30 and affect the passage of gas, the rotating rod 41 is driven to rotate, so that the original filter plate 30 in the air intake box 20 is rotated out of the air intake box 20, and the adjacent filter plate 30 is rotated into the air intake box 20 and replaces the original filter plate 30, thereby realizing the replacement of the filter plate 30, increasing the gas circulation rate, and thereby improving the efficiency of compressing the gas.

[0037] Reference Figure 2 and Figure 4 When the rotating rod 41 rotates, the filter plate 30 in the air intake box 20 will gradually separate from the inner wall of the air intake box 20, so that the gas entering from the opening of the air intake box 20 will reach the other side of the filter plate 30 from the gap between the filter plate 30 and the inner wall of the air intake box 20. In order to further filter the air in this case, an arc-shaped mesh plate 22 is fixed in the air intake box 20. The arc-shaped mesh plate 22 is located on the side of the filter plate 30 close to the intake pipe 92, and the arc-shaped mesh plate 22 is arranged along the moving trajectory of the filter plate 30.

[0038] When the gas reaches the other side of the filter plate 30 from the gap between the filter plate 30 and the inner wall of the air intake box 20, the gas needs to pass through the arc-shaped mesh plate 22 to reach the air intake pipe 92, so that the filter plate 30 will be protected by the arc-shaped mesh plate 22 during the replacement process, so that impurities in the gas still cannot directly reach the air intake pipe 92. During this process, there is no need to stop the air intake of the compression cylinder 90, that is, the work of compressing the air continues, thereby improving work efficiency.

[0039] Because the arc-shaped mesh plate 22 is arranged along the moving track of the filter plate 30, when the filter plate 30 is rotated and replaced, the adjacent filter plates 30 will slide on the arc-shaped mesh plate 22, so that the arc-shaped mesh plate 22 can be cleaned and then reach the position where the filter plate 30 was originally located in the air intake box 20.

[0040] Reference Figure 4 and Figure 5 In order to make the gas enter the air inlet box 20 through the opening at the top of the air inlet box 20 during operation, a closing mechanism 50 for blocking the clearance hole 21 is provided on the air inlet box 20. The closing mechanism 50 includes a closing assembly 52 and a driving assembly 51. The closing assembly 52 includes an upper closing plate 521 and a lower closing plate 522. The upper closing plate 521 and the lower closing plate 522 are arranged up and down. The driving assembly 51 is connected to the upper closing plate 521 and the lower closing plate 522 to drive the upper closing plate 521 and the lower closing plate 522 to move closer to or away from each other in the vertical direction. The upper closing plate 521 and the lower closing plate 522 can be sleeved on the filter plate 30. The rotating rod 41 is located between the upper closing plate 521 and the lower closing plate 522. When the upper closing plate 521 and the lower closing plate 522 are both in contact with the rotating rod 41, the upper closing plate 521 and the lower closing plate 522 are spliced ​​to achieve the sealing of the clearance hole 21.

[0041] Reference Figure 4 and Figure 5 , wherein the driving assembly 51 includes a triangular conveyor belt 511, a transmission gear 513 and two transmission racks 514, the triangular conveyor belt is arranged on the air intake box 20, and the triangular conveyor belt 511 includes a driving wheel. Two driven wheels and a belt, the driving wheel and the driven wheel are both rotatably connected in the air intake box 20, and the belt is sleeved on the driving wheel and the three driven wheels to form a triangle. The two driven wheels of the triangular conveyor belt 511 are coaxially fixed with a driven gear 512, the transmission gear 513 is rotatably connected to the air intake box 20, the transmission gear 513 is meshed with one of the driven gears 512, and the transmission rack 514 is arranged in the vertical direction, and the two transmission racks 514 are respectively fixed on the upper closing plate 521 and the lower closing plate 522, one of the transmission racks 514 is meshed with the transmission gear 513, and the other transmission rack 514 is meshed with the other driven gear 512.

[0042] When the clearance hole 21 needs to be opened or closed, the driving wheel is driven to rotate, so that the two driven wheels drive the driven gear 512 to rotate synchronously, and one of the driven gears 512 drives the transmission gear 513 to rotate, so that the rotation directions of the driven gear 512 and the transmission gear 513 are opposite. Since the two transmission racks 514 are respectively engaged with the transmission gear and the driven gear 512, that is, the movement directions of the two transmission racks 514 are opposite, the upper closing plate 521 and the lower closing plate 522 are moved closer to each other to close the clearance hole 21, or moved away from each other to open the clearance hole 21.

[0043] When one of the filter plates 30 on the rotating rod 41 is horizontally mounted in the air intake box 20, two filter plates 30 will be aligned with the upper closing plate 521 and the lower closing plate 522 respectively, and the upper closing plate 521 and the lower closing plate 522 are driven to approach each other, so that the upper closing plate 521 is sleeved on the corresponding filter plate 30, and the lower closing plate 522 is also sleeved on the corresponding filter plate 30, until the upper closing plate 521 and the lower closing plate 522 are spliced ​​together to block the clearance hole 21, thereby closing the clearance hole 21. The filter plate 30 is inserted in the upper closing plate and the lower closing plate 522, and also plays a positioning role, so that the rotating rod 41 cannot rotate, thereby improving the stability of the filter plate 30 located in the air intake box 20 horizontally mounted in the air intake box 20.

[0044] Reference Figure 3 and Figure 6 In order to clean the filter plate 30 that is rotated out of the air intake box 20, a brush plate 60 is connected to the upper closing plate 521 through a connecting rod 61, and the brush plate 60 can abut against the filter plate 30 located outside the air intake box 20. When the filter plate 30 is replaced, the upper closing plate 521 moves downward, so that the connecting rod 61 moves downward with the brush plate 60, and when the upper closing plate 521 and the lower closing plate 522 are spliced, the brush plate 60 abuts against the filter plate 30, wherein after the filter plate 30 is rotated out of the air intake box 20, the side of the filter plate 30 that originally faces upward in the air intake box 20 will turn downward, so that the impurities accumulated on the filter plate 30 can fall off. At the same time, the brush plate 60 abuts against the filter plate 30, so that the brush on the brush plate 60 penetrates the pores on the filter plate 30, which is convenient for pushing out the impurities, thereby cleaning the filter plate 30.

[0045] Reference Figure 3 and Figure 6 In order to increase the cleaning force of the brush plate 60, a sleeve 70 is sleeved on the connecting rod 61, and the sleeve 70 is fixed to the brush plate 60. A coil spring 71 is arranged in the sleeve 70, and the coil spring 71 is sleeved on the connecting rod 61. One end of the coil spring 71 is fixed to the sleeve 70, and the other end is fixed to the connecting rod 61. A rotating component 80 is provided on the air intake box 20.

[0046] Reference Figure 3 and Figure 6 The rotating assembly 80 includes a moving block 81 and a moving spring 82. A mounting rod 23 is fixed to the air intake box 20. A mounting hole 231 is provided on the mounting rod 23. The moving block 81 is inserted in the mounting hole 231 and can move in the mounting hole 231. The moving spring 82 is provided in the mounting hole 231. One end of the moving spring 82 is fixed to the moving block 81, and the other end is fixed to the inner wall of the mounting hole 231. A guide surface 811 is cut on the side of the moving block 81 close to the brush plate 60. The end of the guide surface 811 close to the connecting rod 61 is inclined upward. A rotating groove 72 is provided on the side wall of the sleeve 70. The rotating groove 72 is spirally arranged around the circumferential trajectory of the sleeve 70. The moving block 81 is inserted in the rotating groove 72 and can move in the rotating groove 72 to drive the sleeve 70 to rotate.

[0047] When the upper closing plate 521 drives the brush plate 60 to move downward, the moving block 81 moves vertically relative to the sleeve 70. Since the position of the moving block 81 is fixed, the moving block 81 applies an oblique thrust to the inner wall of the rotating groove 72, thereby causing the moving block 81 to move relatively in the rotating groove 72 along the trajectory of the rotating groove 72, that is, the sleeve 70 rotates around the connecting rod 61. When the brush plate 60 moves to abut against the filter plate 30, the moving block 81 moves relatively out of the top opening of the rotating groove 72. At this time, the sleeve 70 is reversed under the action of the coil spring 71.

[0048] When the filter plate 30 needs to be replaced again, the upper closing plate 521 drives the brush plate 60 to move upward. At this time, the end wall of the sleeve 70 abuts against the guide surface 811 on the moving block 81. The guide surface 811 plays a guiding role, so that the sleeve 70 slides relatively on the guide surface 811, so that the moving block 81 squeezes the moving spring 82 and is stored in the mounting hole 231, which is convenient for the sleeve 70 to pass through. When the clearance hole 21 is fully opened, the height of the sleeve 70 makes the moving block 81 just align with the rotating groove 72. Under the elastic force of the moving spring 82, the moving block 81 is inserted into the rotating groove 72. Repeat the above steps to realize the rotation and accumulation of force when the sleeve 70 moves downward. After moving down to the right position, the sleeve 70 is reset, and the brush plate 60 is cleaned on the filter plate 30.

[0049] The implementation principle of a centrifugal air compressor device in an embodiment of the present application is as follows: when in use, external air enters the air intake box 20 from the top opening of the air intake box 20, then passes through the filter plate 30 to reach the air intake pipe 92, and enters the compression cylinder 90 along the air intake pipe 92. At this time, the rotating motor 112 is started to drive the rotating rod 110 to rotate with the compression screw 111, and the compression screw 111 cooperates with a number of protrusions 91 to continuously squeeze the air, thereby compressing the air, and the compressed gas is discharged through the exhaust pipe 93.

[0050] During this process, the filter plate 30 makes the gas entering the air intake box 20 need to pass through the filter plate 30 before reaching the air intake pipe 92, and the pores on the filter plate 30 limit the passage of impurities carried by the air, so that the impurities in the air are left on the side of the filter plate 30 away from the air intake pipe 92, thereby improving the cleanliness of the gas entering the air intake pipe 92, so that it is not easy for impurities to accumulate in the compression cylinder 90 and affect the rotation of the compression screw 111, thereby improving the efficiency of compressed air. At the same time, when a large amount of impurities accumulate on the filter plate 30 and affect the passage of gas, the replacement component 40 is started to directly replace the filter plate 30 in the air intake box 20, thereby improving the gas circulation rate and thus improving the efficiency of compressed gas.

[0051] The present application also discloses a method for using a centrifugal air compressor device, comprising the following steps: S1, the gas in the air intake box 20 passes through the filter plate 30 and enters the air intake pipe 92, and the gas flows along the air intake pipe 92 to the compression cylinder 90; S2, the compression screw 111 rotates, so that the compression screw 111 and the bump 91 cooperate to continuously squeeze the gas, so that the other compressed gas flows in the air duct, and the compressed gas is discharged through the exhaust pipe 93; S3, using the driving assembly 51 to drive the closing assembly 52 to open, so that when the rotating rod 41 rotates, it can drive the filter plate 30 to enter and exit the air inlet box 20, thereby achieving the replacement of the filter plate 30; S4. After the filter plate 30 is replaced, the driving assembly 51 is used to drive the sealing assembly 52 to return to its original position, so as to close the clearance hole 21.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
