[0002] The air compressor intake filter is a filtration device that removes solid dust, oil and gas particles, liquid substances, and other impurities. It is a key factor in ensuring the safe, efficient, and economical operation of centrifugal air compressors. Because the air compressor intake filter has a built-in self-cleaning backflush system, over its service life and the influence of the on-site environment, after 3-4 months of use, the self-cleaning backflush system will cause the intake filter pressure to increase, from less than 250 Pa to 280-300 Pa, and the pressure trend continues to rise. Adjustments to the backflush pressure and backflush time have not shown significant results, necessitating a shutdown for inspection. The existing method of shutting down the machine, removing the filter, and cleaning it with compressed air using a handheld hose can result in incomplete cleaning or even damage. Using an uncleaned or damaged filter poses a safety hazard to the air compressor, reduces its efficiency, and increases its economical power consumption. Furthermore, cleaning efficiency is low, and personnel are exposed to dust during the cleaning process, inevitably inhaling dust that affects their respiratory health. Utility Model Content

[0016] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. Parts not described in detail in the following embodiments of the present invention, such as the models and specifications of the secondary control valve and the main control valve, should be immediately known to those skilled in the art or should be known to the prior art.

[0017] like Figure 1 The figure shows an air compressor intake filter cleaning tool, comprising three welded cleaning tool bodies 1, each 1050 mm tall. Each cleaning tool body 1 comprises a rectangular support frame 102, a rotating tray 103 rotatably mounted above the support frame 102, an inner air pipe 105 extending through the rotating tray 103, and an outer air pipe 104 mounted on the support frame 102 and located outside the corresponding rotating tray 103. Both the inner air pipe 105 and the outer air pipe 104 are DN25 mm steel pipes.

[0018] The support frame 102 has multiple legs at its bottom, which can keep the support frame 102 off the ground. A gas pipe 101 for delivering compressed air is installed on the side of the support frame 102, and a mounting hole is provided on the side of the support frame 102 for the gas pipe 101 to pass through the middle of the support frame 102.

[0019] One end of the gas distribution pipe 101 passing through the middle of the support frame 102 is connected to the lower end of the inner gas pipe 105 distributed vertically. A connecting hole is opened on the upper side of the support frame 102 through which the gas distribution pipe 101 is passed. The lower end of the outer gas pipe 104 distributed vertically passes through the connecting hole and is connected to the gas distribution pipe 101.

[0020] Rotating tray 103 supports filter element 6. A mounting hole is provided in the center of rotating tray 103. An inner air pipe 105 passes through this hole and is positioned directly above the center of support frame 102. Rotating tray 103 is rotatably suspended from support frame 102 via a bearing and can rotate around inner air pipe 105. The bearing is a deep groove ball bearing, the outer ring of which is connected to the bottom surface of rotating tray 103, and the inner ring of which is fixedly connected to inner air pipe 105 via a sleeve.

[0021] The rotating tray 103 is provided with a downward pressing fixing assembly 106, which is used to fix the filter element 6 on the rotating tray 103. The downward pressing fixing assembly 106 includes two fixed vertical rods 1061 and a downward pressing connecting rod 1062. The two fixed vertical rods 1061 are symmetrically arranged on the upper side surface of the rotating tray 103 near its outer peripheral side. The downward pressing connecting rod 1062 is movably installed between the upper ends of the two fixed vertical rods 1061. The downward pressing connecting rod 1062 is pressed against the upper end of the filter element 6 placed on the rotating tray 103 to fix the filter element 6 on the rotating tray 103. Secondly, the two ends of the downward pressing connecting rod 1062 are fixed to the two fixed vertical rods 1061 by bolts. The position of the downward pressing connecting rod 1062 on the two fixed vertical rods 1061 can be adjusted according to the tightening bolts, so that the downward pressing connecting rod 1062 can press down and fix filter elements 6 of different heights.

[0022] Both the inner air pipe 105 and the outer air pipe 104 are obliquely provided with multiple air outlet holes. The air outlet holes on the inner air pipe 105 are inner air holes. The multiple inner air holes are evenly spaced along the height direction of the inner air pipe 105. The spacing between two adjacent inner air holes is 50 mm. The aperture of the inner air holes is 5 mm. The compressed gas flow ejected from the inner air holes is tangent to the inner surface of the filter element 6, so that after the compressed air is introduced into the inner air pipe 105, the compressed air can be ejected from the inner air holes to the inner surface of the filter element 6 to push the filter element 6 to rotate synchronously with the rotating tray 103. The compressed air ejected from the inner air holes can be sprayed onto the inner circumference of the filter element 6 as the filter element 6 rotates. The compressed air can blow off the dust on the inner circumference of the filter element 6 and complete the cleaning of the inner surface of the filter element 6.

[0023] Secondly, the air outlet holes on the outer air pipe 104 are arranged on the side facing the filter element 6. The air outlet holes on the outer air pipe 104 are outer air holes. Multiple outer air holes are evenly spaced along the height direction of the outer air pipe 104. The spacing between two adjacent outer air holes is 50 mm. The aperture of the outer air holes is 5 mm. The compressed gas flow ejected from the outer air holes is tangent to the outer surface of the filter element 6, so that after the compressed air is introduced into the outer air pipe 104, the compressed air can be ejected from the outer air holes to the outer surface of the filter element 6 to push the filter element 6 to rotate synchronously with the rotating tray 103. The compressed air ejected from the outer air holes can be sprayed onto the outer peripheral surface of the filter element 6 as the filter element 6 rotates. The compressed air can blow off the dust on the outer peripheral surface of the filter element 6 and complete the cleaning of the outer surface of the filter element 6. The outer air holes on the outer air pipe 104 and the inner air holes on the inner air pipe 105 blow out compressed air synchronously, and the compressed gas is blown onto the filter element 6 synchronously, which can push the filter element 6 to drive the rotating tray 103 to rotate synchronously, thereby completing the cleaning work of the filter element 6 efficiently and quickly, greatly improving the cleaning efficiency.

[0024] Furthermore, the three gas branch pipes 101 on the three cleaning tool bodies 1 are connected to a gas branch main pipe 2 at one end away from their corresponding inner air pipes 105. The gas branch main pipe 2 has three mounting holes evenly spaced along its length direction on one side facing the three gas branch pipes 101, and the three gas pipelines 4 are connected to the gas branch main pipe 2 through the mounting holes on the corresponding sides.

[0025] A Y-shaped gas distribution pipe 3 is connected to the other side of the gas distribution main pipe 2 opposite to the gas transmission branch pipe 101. Two mounting holes are provided on the gas distribution main pipe 2 along its length for the installation and connection of the two upper ends of the Y-shaped gas distribution pipe 3. The lower end of the Y-shaped gas distribution pipe 3 is connected to the gas storage tank 5 through the gas transmission pipe 4. A reducing pipe clamp 301 is provided at the lower end of the Y-shaped gas distribution pipe 3, and the Y-shaped gas distribution pipe 3 can be detachably connected to the gas transmission pipe 4 through the reducing pipe clamp 301.

[0026] Moreover, a main control valve 501 for controlling the on and off of compressed air is installed at one end of the gas pipeline 4 connected to the gas storage tank 5, so that the cleaning personnel can control the on and off of the compressed air through the main control valve 501 at a position away from the cleaning of the filter element 6. When cleaning the filter element 6, the cleaning personnel can control the cleaning of the filter element 6 away from the working area of ​​the filter element 6, thereby reducing the exposure to dust and affecting their health.

[0027] Furthermore, a secondary control valve 1011 is installed on each of the three gas supply pipes 101. The setting of the secondary control valve 1011 can control the on and off of the compressed air in a single cleaning tool body 1. When there is only one filter element 6 that needs to be cleaned on the three cleaning tool bodies 1, only the corresponding secondary control valve 1011 needs to be opened to let in compressed air, thereby saving the use of compressed air.

[0028] The process of cleaning the filter element of the present invention is as follows: first, connect the gas supply pipe 4 to the lower end of the Y-shaped gas distribution pipe 3, then place the filter element 6 on the rotating tray 103, adjust the downward pressure connecting rod 1062 to press against the upper end of the filter element 6 to fix it on the rotating tray 103, then open the secondary control valve 1011 on the corresponding gas supply branch pipe 101, and then open the main control valve 501 to allow compressed air to pass. The compressed gas is ejected from the inner and outer air holes onto the inner and outer surfaces of the filter element 6. Then, the filter element 6 and the rotating tray 103 rotate synchronously until the dust on the filter element 6 is cleaned.
