Description

Technical Field

[0001] This application relates to the field of air compressors, and more particularly to a centrifugal air compressor device and its method of use. Background Technology

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

[0003] In related technologies, Chinese patent CN109209871B discloses a centrifugal air compressor, including an air compressor body. The air compressor body is provided with a placement platform. A compression chamber and an air intake mechanism are respectively installed on the top two sides of the placement platform. An installation cavity is provided inside the compression chamber. A cooling channel is provided in the interlayer between the installation cavity and the compression chamber. Several docking protrusions are fixedly installed on the inner walls of both sides of the installation cavity. A primary filter, a secondary filter, and a non-woven fabric layer are sequentially installed between the inner walls of both sides of the air intake chamber. The air entering the compression chamber is clean through filtration by the primary filter, the secondary filter, and the non-woven fabric layer.

[0004] The essence of gas filtration is to block impurities in the gas by blocking them on the primary filter, secondary filter, and non-woven fabric layer. However, after long-term use, a lot of impurities will accumulate on the primary filter, secondary filter, and non-woven fabric layer, thus affecting the passage of gas. At the same time, the primary filter, secondary filter, and non-woven fabric layer are located inside the air inlet, making them inconvenient to clean and replace, which in turn affects work efficiency. Therefore, improvements are needed. Summary of the Invention

[0005] To address the problem of excessive impurities accumulating on the primary filter, secondary filter, and non-woven fabric layer, which impede gas passage and reduce working efficiency, this application provides a centrifugal air compressor device and its usage method.

[0006] Firstly, the centrifugal air compressor device provided in this application adopts the following technical solution:

[0007] A centrifugal air compressor device includes a worktable, a compression cylinder, and an air inlet box. The compression cylinder is disposed on the worktable and contains a compression screw. A rotating rod is coaxially inserted into the compression cylinder and driven to rotate by a rotary motor. The compression screw is sleeved on the rotating rod. Several protrusions are provided on the inner wall of the compression cylinder, and an air duct is formed between the compression screw and the protrusions for gas flow. The top of the air inlet box is open, and the bottom of the air inlet box is connected to the compression cylinder through an air inlet pipe. An exhaust pipe is connected to the bottom wall of the compression cylinder. A filter plate is provided in the air inlet box to prevent gas from entering the air inlet pipe. A replacement assembly is provided on the air inlet box and is connected to the filter plate for replacing the filter plate.

[0008] By adopting the above technical solution, when in use, the outside gas enters the air intake box through 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 through the air intake pipe. At this time, the rotary motor is started, driving the rotary rod to rotate with the compression screw. The compression screw cooperates with several protrusions to continuously squeeze the air, thereby compressing the air. The compressed gas is discharged through the exhaust pipe.

[0009] During this process, the filter plate ensures that all gas entering the intake chamber passes through it before reaching the intake pipe. The pores in the filter plate restrict the passage of air-entrained impurities, trapping them on the side of the filter plate away from the intake pipe. This improves the cleanliness of the gas entering the intake pipe, preventing impurities from accumulating inside the compressor cylinder and affecting the rotation of the compressor screw, thus increasing the efficiency of compressed air. Furthermore, when significant impurities accumulate on the filter plate, obstructing gas flow, the replacement assembly is activated to directly replace the filter plate in the intake chamber, increasing the gas flow rate and further improving the efficiency of compressed gas.

[0010] Optionally, the replacement assembly includes a rotating rod and a rotating motor. The rotating rod passes through the air intake box, and its end is rotatably connected to the inner wall of the air intake box. The rotating motor is mounted on the air intake box, and its output end is coaxially fixed with one end of the rotating rod to drive the rotating rod to rotate. The rotating rod is provided with a plurality of filter plates, which are arranged radially with the rotating rod as the center. A clearance hole is provided on one side of the air intake box for the filter plates to move, and a closing mechanism is provided on the air intake box to close the clearance hole.

[0011] By adopting the above technical solution, after long-term use, the side of the filter plate away from the air inlet pipe is prone to accumulating more impurities, which will block the pores on the filter plate and affect the gas flow rate. At this time, the rotating motor is started to drive the rotating rod to rotate, which will cause the filter plate with accumulated impurities to flip out of the air inlet box through the clearance hole. Meanwhile, the adjacent filter plate will flip out of the air inlet box from the outside of the air inlet box through the clearance hole and enter the air inlet box to replace the original filter plate, thereby realizing the replacement of the filter plate and making the gas flow less affected.

[0012] Optionally, the sealing mechanism includes a drive assembly and a sealing assembly. The drive assembly is disposed on the air intake box, and the sealing assembly is connected to the drive assembly. The drive assembly is used to drive the sealing assembly to move in order to close or open the clearance hole.

[0013] By adopting the above technical solution, when a filter plate is horizontally mounted between the top opening of the air intake box and the air intake pipe, the drive component is activated to drive the sealing component 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 must be filtered by the filter plate.

[0014] Optionally, the sealing assembly includes an upper sealing plate and a lower sealing plate, which are arranged vertically. Both the upper and lower sealing plates can be fitted onto the filter plate. When the upper and lower sealing plates abut against each other, they are used to seal the clearance hole.

[0015] 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 and lower sealing plates respectively. At this time, the driving component drives the upper and lower sealing plates to move closer to each other, so that the upper sealing plate is fitted onto the corresponding filter plate, and the lower sealing plate is also fitted onto the corresponding filter plate, until the upper and lower sealing plates are spliced ​​together, blocking the clearance hole and achieving closure of the clearance hole. The filter plates inserted in the upper and lower sealing plates also play a positioning role, preventing the rotating rod from rotating, thereby improving the stability of the filter plates horizontally mounted in the air intake box.

[0016] Optionally, the drive assembly includes a triangular conveyor belt, a transmission gear, and two transmission racks. The triangular conveyor belt is rotatably connected to the air intake box. Each of the two driven pulleys of the triangular conveyor belt has a driven gear coaxially fixed on it. The transmission gear is rotatably connected to the air intake box and meshes with one of the driven gears. The transmission racks are arranged vertically, and the two transmission racks are respectively fixed to the upper and lower sealing plates. One of the transmission racks meshes with the transmission gear, and the other transmission rack meshes with the other driven gear.

[0017] By adopting the above technical solution, the triangular conveyor belt is driven to move, causing the two driven wheels to drive the driven gear to rotate synchronously. One of the driven gears drives the transmission gear to rotate, so that the driven gear and the transmission gear rotate in opposite directions. Since the two transmission racks mesh with the transmission gear and the driven gear respectively, that is, the two transmission racks move in opposite directions, so that the upper and lower closing plates move closer to each other to close the clearance hole, or move further apart to open the clearance hole.

[0018] Optionally, the air intake box is provided with an arc-shaped mesh plate, which is located on the side of the filter plate near the air intake pipe and is arranged along the moving trajectory of the filter plate.

[0019] By adopting the above technical solution, when the rotating rod drives the filter plate to move, the filter plate located in the air inlet box separates from the inner wall of the air inlet box. This allows the gas entering from the opening of the air inlet box to pass through the gap between the filter plate and the inner wall of the air inlet box to the other side of the filter plate. Then, the gas needs to pass through the arc-shaped mesh plate to reach the air inlet pipe. The arc-shaped mesh plate ensures that impurities in the gas cannot directly reach the air inlet pipe during the filter plate replacement process. During this process, there is no need to stop the air intake of the compression cylinder, that is, the compressed air operation continues, improving work efficiency.

[0020] Because the arc-shaped mesh plate is arranged along the moving trajectory of the filter plate, during the rotation and replacement of the filter plate, the adjacent filter plate will slide on the arc-shaped mesh plate, so that the arc-shaped mesh plate is cleaned and reaches the original position of the filter plate in the air intake box.

[0021] Optionally, a brush plate is connected to the upper sealing plate via a connecting rod, and the brush plate can abut against the filter plate located outside the air intake box.

[0022] By adopting the above technical solution, when the filter plate is replaced, the upper sealing plate moves downward, causing the connecting rod to move the brush plate downward as well. When the upper and lower sealing plates are joined, the brush plate abuts against the filter plate. After the filter plate rotates out of the air inlet box, the side of the filter plate that was originally facing upward inside the air inlet box will flip downward, allowing accumulated impurities on the filter plate to fall off. Simultaneously, the abutting of the brush plate against the filter plate allows the brushes on the brush plate to penetrate the pores in the filter plate, facilitating the removal of impurities and achieving cleaning of the filter plate.

[0023] Optionally, a sleeve is fitted onto the connecting rod, the sleeve is fixed to the brush plate, a coil spring is provided inside the sleeve, the coil spring is fitted onto 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, the rotating assembly is connected to the sleeve, and the rotating assembly is used to drive the sleeve to rotate.

[0024] By adopting the above technical solution, when the upper sealing plate moves the brush plate downward, the rotating component drives the sleeve to rotate. At this time, the coil spring gradually coils up. When the upper sealing plate and the lower sealing plate are joined together, the brush plate comes into contact with the filter plate outside the air intake box. At this time, the sleeve separates from the rotating component, the coil spring is released, and the sleeve is driven to reverse, thereby driving the brush plate to rotate and slide on the filter plate, thus cleaning the filter plate.

[0025] Optionally, the rotating assembly includes a moving block and a moving spring. A mounting rod is fixed on the air intake box, and a mounting hole is provided on the mounting rod. The moving block is inserted into the mounting hole and can move within 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 near the brush plate. When the guide surface abuts against the sleeve, it is used to drive the moving block to be housed in the mounting hole. A rotating groove is provided on the side wall of the sleeve. The moving block is inserted into the rotating groove and can move within the rotating groove to drive the sleeve to rotate.

[0026] By adopting the above technical solution, when the upper sealing 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 pushing force to the inner wall of the rotating groove, thereby causing the moving block to move relative to 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 relative to the top opening of the rotating groove. At this time, the sleeve reverses under the action of the coil spring.

[0027] When the filter plate needs to be replaced again, the upper sealing plate moves the brush plate upward. At this time, the end wall of the sleeve abuts against the guide surface on the moving block. The guide surface acts as a guide, allowing the sleeve to slide relative to the guide surface. This causes the moving block to compress the moving spring and be housed in the mounting hole, facilitating the passage of the sleeve. Until the clearance hole is fully open, the height of the sleeve aligns the moving block precisely with the rotating groove. Under the elastic force of the moving spring, the moving block is inserted into the rotating groove. The above steps are repeated to achieve rotational force storage when the sleeve moves downward. After moving to the correct position, the sleeve resets, completing the cleaning of the brush plate on the filter plate.

[0028] On the other hand, the method of using a centrifugal air compressor device provided in this application adopts the following technical solution:

[0029] S1. The gas in the intake box passes through the filter plate and enters the intake pipe. The gas then travels along the intake pipe into the compressor cylinder.

[0030] S2. The compressor screw rotates, causing the compressor screw and the cam to work together to continuously compress the gas, thereby causing other compressed gas to flow in the air duct, and the compressed gas is discharged through the exhaust pipe.

[0031] S3. Using the drive component, the sealing component is opened, so that when the rotating rod rotates, it can drive the filter plate in and out of the air inlet box to realize the replacement of the filter plate.

[0032] S4. After the filter plate is replaced, use the drive component to reset the sealing component to close the clearance hole.

[0033] In summary, this application includes at least one of the following beneficial effects:

[0034] 1. The filter plate ensures that all gas entering the intake chamber passes through it before reaching the intake pipe. The pores in the filter plate restrict the passage of air-entrained impurities, trapping them on the side of the filter plate away from the intake pipe. This improves the cleanliness of the gas entering the intake pipe, preventing impurities from accumulating inside the compressor cylinder and affecting the rotation of the compressor screw, thus improving compressed air efficiency. Furthermore, when significant impurities accumulate on the filter plate, obstructing gas flow, the replacement assembly can be activated to directly replace the filter plate in the intake chamber, increasing the gas flow rate and further enhancing compressed gas efficiency.

[0035] 2. When the filter plate needs to be replaced, the upper sealing plate moves the brush plate upward. At this time, the end wall of the sleeve abuts against the guide surface on the moving block. The guide surface acts as a guide, allowing the sleeve to slide relative to the guide surface. This causes the moving block to compress the moving spring and be housed in the mounting hole, facilitating the passage of the sleeve. Until the clearance hole is fully open, the height of the sleeve ensures that the moving block is aligned 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 replacement is completed, the upper sealing plate moves the sleeve downward. The moving block moves relative to the sleeve in the rotating groove, allowing it to rotate and store force as it moves downward. After moving to the correct position, the moving block moves out of the rotating groove, and the sleeve resets under the action of the coil spring, completing the cleaning of the brush plate on the filter plate.

Detailed Implementation

[0043] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0044] This application discloses a centrifugal air compressor device. (Refer to...) Figure 1 and Figure 2 The centrifugal air compressor unit includes a workbench 10, a compression cylinder 90, and an air inlet box 20. The compression cylinder 90 is located on the workbench 10. A compression screw 111 is installed 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 rotary motor 112. The compression screw 111 is sleeved on the rotating rod 110. Several 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 to allow gas to flow. The top of the air inlet box 20 is open. The bottom of the air inlet box 20 is connected to the compression cylinder 90 through an air inlet pipe 92. An exhaust pipe 93 is connected to the bottom wall of the compression cylinder 90.

[0045] In use, outside air enters the air intake box 20 through the top opening of the air intake box 20, then enters the air intake pipe 92, and enters the compression cylinder 90 through the air intake pipe 92. At this time, the rotary motor 112 is started, driving the rotary rod 110 to rotate the compression screw 111. The compression screw 111 cooperates with several protrusions 91 to continuously squeeze the air, thereby compressing the air. The compressed gas is discharged through the exhaust pipe 93.

[0046] Reference Figure 3 and Figure 4A clearance hole 21 is provided through 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, and the end of the rotating rod 41 is rotatably connected to the air intake box 20. The rotating motor 42 is bolted to the air intake box 20, and 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. Several filter plates 30 are installed on the rotating rod 41. The filter plates 30 are arranged along the length of the rotating rod 41 and are arranged radially with the rotating rod 41 as the center. When the rotating rod 41 rotates, it drives the filter plates 30 to move, so that the filter plates 30 pass through the clearance hole 21 and enter and exit the air intake box 20.

[0047] The filter plate 30 can be inserted into the air intake box 20, and the circumferential sidewall 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 upper and lower areas. This ensures that all gas entering the air intake box 20 from the top opening must pass through the filter plate 30 before reaching the lower air intake pipe 92, thus achieving gas filtration. The pores on the filter plate 30 restrict the passage of impurities carried by the air, so that impurities in the air are retained on the side of the filter plate 30 away from the air intake pipe 92, improving the cleanliness of the gas entering the air intake pipe 92. This makes it less likely for impurities to accumulate inside the compression cylinder 90, affecting the rotation of the compression screw 111, and thus improving the efficiency of compressed air.

[0048] Meanwhile, when a lot of impurities accumulate on the filter plate 30 and affect the passage of gas, the rotating rod 41 is driven to rotate, causing the original filter plate 30 in the intake box 20 to rotate out of the intake box 20, while the adjacent filter plate 30 rotates into the intake box 20 and replaces the original filter plate 30, thereby realizing the replacement of the filter plate 30, improving the gas flow rate, and thus improving the efficiency of compressed gas.

[0049] 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 through the gap between the filter plate 30 and the inner wall of the air intake box 20. In order to further filter the air under this condition, 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 near the air intake pipe 92, and the arc-shaped mesh plate 22 is arranged along the moving trajectory of the filter plate 30.

[0050] When the gas reaches the other side of the filter plate 30 through the gap between the filter plate 30 and the inner wall of the air inlet box 20, the gas needs to pass through the arc-shaped mesh plate 22 to reach the air inlet pipe 92. This ensures that the filter plate 30 is protected by the arc-shaped mesh plate 22 during the replacement process, so that impurities in the gas cannot directly reach the air inlet pipe 92. During this process, there is no need to stop the air intake of the compression cylinder 90, that is, the operation of compressed air continues, which improves work efficiency.

[0051] As the arc-shaped mesh plate 22 is arranged along the moving trajectory of the filter plate 30, during the rotation and replacement process of the filter plate 30, the adjacent filter plates 30 will slide on the arc-shaped mesh plate 22, so that the arc-shaped mesh plate 22 is cleaned and reaches the original position of the filter plate 30 in the air intake box 20.

[0052] Reference Figure 4 and Figure 5 To ensure that during operation, the only channel for gas to enter the intake box 20 is the opening at the top of the intake box 20, a sealing mechanism 50 is provided on the intake box 20 to seal the clearance hole 21. The sealing mechanism 50 includes a sealing component 52 and a driving component 51. The sealing component 52 includes an upper sealing plate 521 and a lower sealing plate 522, which are arranged vertically. The driving component 51 is connected to the upper sealing plate 521 and the lower sealing plate 522 and is used to drive the upper sealing plate 521 and the lower sealing plate 522 to move closer or further apart in the vertical direction. Both the upper sealing plate 521 and the lower sealing plate 522 can be fitted onto the filter plate 30. The rotating rod 41 is located between the upper sealing plate 521 and the lower sealing plate 522. When both the upper sealing plate 521 and the lower sealing plate 522 abut against the rotating rod 41, the upper sealing plate 521 and the lower sealing plate 522 are spliced ​​together to seal the clearance hole 21.

[0053] Reference Figure 4 and Figure 5 The drive assembly 51 includes a triangular conveyor belt 511, a transmission gear 513, and two transmission racks 514. The triangular conveyor belt is mounted on the air intake box 20. The triangular conveyor belt 511 includes a drive pulley, two driven pulleys, and a belt. The drive pulley and driven pulleys are rotatably connected in the air intake box 20. The belt is fitted onto the drive pulley and three driven pulleys, forming a triangle. Driven gears 512 are coaxially fixed on the two driven pulleys of the triangular conveyor belt 511. The transmission gear 513 is rotatably connected to the air intake box 20 and meshes with one of the driven gears 512. The transmission racks 514 are arranged vertically and are fixed on the upper sealing plate 521 and the lower sealing plate 522, respectively. One transmission rack 514 meshes with the transmission gear 513, and the other transmission rack 514 meshes with the other driven gear 512.

[0054] When it is necessary to open or close the clearance hole 21, the driving wheel is rotated, causing the two driven wheels to drive the driven gear 512 to rotate synchronously. One of the driven gears 512 drives the transmission gear 513 to rotate, so that the driven gear 512 and the transmission gear 513 rotate in opposite directions. Since the two transmission racks 514 mesh with the transmission gear and the driven gear 512 respectively, that is, the two transmission racks 514 move in opposite directions, so that the upper closing plate 521 and the lower closing plate 522 move closer to each other to close the clearance hole 21, or move further apart to open the clearance hole 21.

[0055] 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 align with the upper sealing plate 521 and the lower sealing plate 522 respectively. At this time, the upper sealing plate 521 and the lower sealing plate 522 are driven to move closer to each other, so that the upper sealing plate 521 is fitted onto the corresponding filter plate 30, and the lower sealing plate 522 is also fitted onto the corresponding filter plate 30, until the upper sealing plate 521 and the lower sealing plate 522 are spliced ​​together, blocking the clearance hole 21 and closing the clearance hole 21. The filter plates 30 inserted in the upper sealing plate and the lower sealing plate 522 also play a positioning role, preventing the rotating rod 41 from rotating, thereby improving the stability of the filter plates 30 horizontally mounted in the air intake box 20.

[0056] Reference Figure 3 and Figure 6 To clean the filter plate 30 exiting the intake box 20, a brush plate 60 is connected to the upper sealing plate 521 via a connecting rod 61. The brush plate 60 can abut against the filter plate 30 located outside the intake box 20. When the filter plate 30 is replaced, the upper sealing plate 521 moves downward, causing the connecting rod 61 to move the brush plate 60 downward as well. When the upper sealing plate 521 and the lower sealing plate 522 are joined, the brush plate 60 abuts against the filter plate 30. After the filter plate 30 exits the intake box 20, the side of the filter plate 30 that was originally facing upward inside the intake box 20 will flip downward, allowing the impurities accumulated on the filter plate 30 to fall off. At the same time, the abutment between the brush plate 60 and the filter plate 30 allows the brushes on the brush plate 60 to penetrate the holes in the filter plate 30, facilitating the removal of impurities and cleaning the filter plate 30.

[0057] Reference Figure 3 and Figure 6 To increase the cleaning power of the brush plate 60, a sleeve 70 is fitted on the connecting rod 61. The sleeve 70 is fixed to the brush plate 60. A coil spring 71 is provided inside the sleeve 70. The coil spring 71 is fitted 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 assembly 80 is provided on the air intake box 20.

[0058] Reference Figure 3 and Figure 6 The rotating assembly 80 includes a movable block 81 and a movable spring 82. A mounting rod 23 is fixed to the air intake box 20, and a mounting hole 231 is formed on the mounting rod 23. The movable block 81 is inserted into the mounting hole 231 and can move within it. The movable spring 82 is located in the mounting hole 231, with one end fixed to the movable block 81 and the other end fixed to the inner wall of the mounting hole 231. A guide surface 811 is cut on the side of the movable block 81 near the brush plate 60, and the guide surface 811 is inclined upwards at the end near the connecting rod 61. A rotating groove 72 is formed on the side wall of the sleeve 70, and the rotating groove 72 is spirally arranged around the circumferential trajectory of the sleeve 70. The movable block 81 is inserted into the rotating groove 72 and can move within it to drive the sleeve 70 to rotate.

[0059] When the upper sealing plate 521 moves the brush plate 60 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 pushing force to the inner wall of the rotating groove 72, thereby causing the moving block 81 to move relative to 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 out from the top opening of the rotating groove 72. At this time, the sleeve 70 reverses under the action of the coil spring 71.

[0060] When the filter plate 30 needs to be replaced again, the upper sealing plate 521 moves the brush plate 60 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 acts as a guide, allowing the sleeve 70 to slide relative to the guide surface 811. This causes the moving block 81 to compress the moving spring 82 and be housed in the mounting hole 231, facilitating the passage of the sleeve 70. Until the clearance hole 21 is fully open, the height of the sleeve 70 is such that the moving block 81 is precisely aligned 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. The above steps are repeated to achieve rotational force storage when the sleeve 70 moves downward. After moving to the lower position, the sleeve 70 returns to its original position, completing the cleaning of the brush plate 60 on the filter plate 30.

[0061] The implementation principle of a centrifugal air compressor device according to an embodiment of this application is as follows: When in use, external gas enters the air inlet box 20 through the top opening of the air inlet box 20, then passes through the filter plate 30 to reach the air inlet pipe 92, and enters the compression cylinder 90 along the air inlet pipe 92. At this time, the rotary motor 112 is started, driving the rotary rod 110 to rotate with the compression screw 111. The compression screw 111 cooperates with several protrusions 91 to continuously squeeze the air, thereby compressing the air. The compressed gas is discharged through the exhaust pipe 93.

[0062] During this process, the filter plate 30 ensures that all gas entering the intake chamber 20 must pass through it before reaching the intake pipe 92. The pores on the filter plate 30 restrict the passage of air-entrained impurities, leaving them on the side of the filter plate 30 furthest from the intake pipe 92. This improves the cleanliness of the gas entering the intake pipe 92, preventing impurities from accumulating inside the compression cylinder 90 and affecting the rotation of the compression screw 111, thereby improving the efficiency of compressed air. Conversely, when a large amount of impurities accumulates on the filter plate 30, obstructing gas flow, the replacement assembly 40 is activated to directly replace the filter plate 30 in the intake chamber 20, increasing the gas flow rate and further improving the efficiency of compressed gas.

[0063] This application also discloses a method of using a centrifugal air compressor device, including the following steps:

[0064] S1. The gas in the intake box 20 passes through the filter plate 30 and enters the intake pipe 92. The gas then travels along the intake pipe 92 into the compression cylinder 90.

[0065] S2. The compression screw 111 rotates, causing the compression screw 111 and the protrusion 91 to work together to continuously compress the gas, thereby causing other compressed gas to flow in the air duct, and the compressed gas is discharged through the exhaust pipe 93.

[0066] S3. Using the drive assembly 51, the sealing assembly 52 is driven to open, so that when the rotating rod 41 rotates, it can drive the filter plate 30 in and out of the air inlet box 20, thereby realizing the replacement of the filter plate 30.

[0067] S4. After the filter plate 30 is replaced, the drive assembly 51 is used to drive the sealing assembly 52 to reset, so as to close the clearance hole 21.

[0068] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
