An inclined airflow guide plate 306 is also fixedly mounted on the upper inner wall of the dust collection chamber 301. The airflow guide plate 306 extends downward toward the air intake plate 302. A fixed seat 307 is fixedly connected to the exhaust end at the top center of the dust collection chamber 301. A drive shaft 308 is rotatably mounted on the fixed seat 307. An impeller 309 is fixedly sleeved on the outer wall of the drive shaft 308. The synchronous air supply assembly 7 includes a wind frame 701, which is fixedly mounted on one side of the top of the built-in plate 6. A secondary shaft 702 is rotatably mounted on the top of the built-in plate 6 near the wind frame 701 via a bearing seat. A fan blade 703 is fixedly mounted at the end of the secondary shaft 702.

[0015] By adopting the above technical solution, with the cooperation of the air intake plate 302, vertical plate 303, arc plate 304 and water swirl guide plate 305, the mixed impurities sucked in can form a high-speed water swirl airflow in the dust collection chamber 301, and achieve solid-liquid separation by using centrifugal force.

[0016] The quick-connect assembly 5 includes an air guide frame 501 and a side plate 502. The side plate 502 is securely mounted to the top of the outer wall of the frame 1 near the dust collection chamber 301 by bolts. A connecting frame 503 is fixedly mounted in the middle of the outer wall of the side plate 502.

A spherical groove 508 is opened in the outer wall of the plug-in frame 504 to cooperate with the damping ball 506.

[0017] By adopting the above technical solution, the air guide frame 501 can be quickly assembled or disassembled by the sliding fit between the plug frame 504 and the connecting frame 503. The damping ball 506 is embedded in the spherical groove 508 for damping and limiting, so as to prevent the air guide frame 501 from coming loose during operation.

[0018] The storage cabinet 4 includes a drawer 401 and a cabinet door 402. The drawer 401 is slidably mounted on the upper inner side of the storage cabinet 4 via a slide rail. The cabinet door 402 is rotatably connected to the lower part of the storage cabinet 4 corresponding to the drawer 401 in the middle. Two symmetrically distributed shelf panels 403 are also fixedly mounted on the inner wall of the storage cabinet 4.

[0019] By adopting the above technical solution, the drawer 401 and cabinet door 402 are set up in separate areas, combined with symmetrical storage boards 403, so as to realize the classified storage of tools and spare parts, effectively improve the utilization rate of storage space, facilitate the quick access to materials during emergency repairs, and meet the needs of efficient on-site operations.

[0020] The exhaust end of the air frame 701 is connected to the air supply frame 704, and the air supply frame 704 is fixedly mounted on the outer wall of the storage cabinet 4. The air supply frame 704 has four equidistantly distributed exhaust channels 705 that cooperate with the storage cabinet 4.

[0021] By adopting the above technical solution, the airflow generated by the rotation of the fan blade 703 is guided into the storage cabinet 4 through the exhaust channel 705 of the air supply frame 704, thereby achieving ventilation and dehumidification of the storage space, preventing tools and spare parts from rusting due to moisture, and blowing away the floating dust in the storage area to keep the storage environment clean.

[0022] The top of the air guide frame 501 is connected to the dust collection frame 509, and the bottom of the air guide frame 501 is connected to the hose 510, with the other end of the hose 510 connected to the air inlet of the dust collection chamber 301.

[0023] By adopting the above technical solution, the air guide frame 501 and the dust collection chamber 301 are flexibly connected through the hose 510, which facilitates the adjustment of the working position of the dust collection frame 509 and improves the operational flexibility of the device.

[0024] The built-in plate 6 is securely mounted to the upper part of the frame 1 by bolts, and the top of the drive shaft 308 is rotatably connected to the built-in plate 6. The drive motor 311 is fixedly mounted on one side of the bottom end of the built-in plate 6, and the drive end of the drive motor 311 is connected to the drive shaft 308 through a belt pulley transmission group.

[0025] By adopting the above technical solution, the drive motor 311 drives the drive shaft 308 to rotate stably.

[0026] The built-in plate 6 is rotatably mounted with a drive shaft 312 near the fixed base 307. The drive shaft 308 is fixedly sleeved with a drive gear 313 on its outer wall. The drive shaft 312 is fixedly sleeved with a driven gear 314 on its outer wall, and the drive gear 313 and the driven gear 314 are meshed together.

[0027] By adopting the above technical solution, the meshing transmission between the drive gear 313 and the driven gear 314 can transmit the power of the drive shaft 308 to the transmission shaft 312. The number of teeth of the drive gear 313 is greater than that of the driven gear 314, forming a gear reduction transmission, thereby achieving a deceleration effect in the power transmission process.

[0028] The drive shaft 312 and the countershaft 702 are connected by a bevel gear set.

[0029] By adopting the above technical solution, the transmission shaft 312 synchronously drives the secondary shaft 702 to rotate during the rotation process.

[0030] The exhaust end of the fixed base 307 is connected to the exhaust pipe 310, and the exhaust pipe 310 is fixedly mounted on the top of the dust collection chamber 301.

[0031] By adopting the above technical solution, the clean airflow separated in the dust collection chamber 301 is discharged directionally through the exhaust pipe 310.

[0032] The cabinet door 402 has a vertical groove that works in conjunction with the exhaust duct 705, and the vertical groove has three vertically equidistant grooves.

[0033] By adopting the above technical solution, the supply airflow enters the storage cabinet 4 through the exhaust duct 705 and then exits from the vertical channel, ensuring the ventilation and dehumidification effect.

[0034] Working principle: First, push the frame 1 to the pump valve emergency repair point, lock the position of the caster brake at the bottom of the frame 1, open the drawer 401 and cabinet door 402 of the storage cabinet 4, take out the tools and spare parts to be used from the shelf 403, and complete the material preparation before the operation. When grinding operations are performed on workbench 2 or at the pump / valve mounting position and require vacuuming, simply manually pull up the air guide frame 501, hold the vacuum frame 509 and align it with the grinding area. Start the drive motor 311 via the control panel 9. The drive motor 311 drives the drive shaft 308 to rotate via the belt pulley transmission assembly. The drive shaft 308 drives the impeller 309 to rotate at high speed within the vacuum chamber 301, generating negative pressure suction. The mixed impurities generated during grinding are drawn into the vacuum chamber 301 through the vacuum frame 509, air guide frame 501, and hose 510 under the suction. Before using the mobile device, appropriate amounts of water are poured into the vacuum chamber 301 through the water inlet pipe. Water is poured in, with the water level slightly higher than the bottom of the vertical plate 303. Impurities are swept into the water in the dust collection chamber 301 at high speed by the airflow. Under the coordinated guidance of the air inlet plate 302, the vertical plate 303, the arc plate 305 and the water vortex guide plate 304, the airflow drives the water to form a high-speed rotating water vortex flow field. With the help of the centrifugal force generated by the water vortex, the denser solid impurities are thrown to the outside of the water and settle to the bottom of the dust collection chamber 301. The oil sludge is dispersed and suspended in the water under the action of the water's adsorption force, realizing the complete separation of solid and liquid impurities from the airflow. The clean airflow enters the fixed seat 307 through the exhaust port at the top of the dust collection chamber 301 and is then discharged directionally through the exhaust pipe 310. The drive shaft 308 transmits power to the transmission shaft 312 through the drive gear 313 and the driven gear 314. The transmission shaft 312 then drives the secondary shaft 702 to rotate through the bevel gear set, which in turn drives the fan blade 703 to rotate and generate airflow. The airflow generated by the fan blade 703 enters the air supply frame 704 through the air frame 701 and forms a flow channel through the exhaust passage 705 and the vertical groove of the cabinet door 402, continuously supplying air into the storage cabinet 4 to ventilate and dehumidify the stored tools and spare parts, and prevent the materials from getting damp and rusting. After the work is completed, turn off the drive motor 311, slide the plug frame 504 of the air guide frame 501 into the connecting frame 503 of the side plate 502. At this time, the damping ball 506 in the damping frame 505 is embedded in the spherical groove 508 under the action of the damping spring 507, so as to quickly fix the air guide frame 501. When the air guide frame 501 is assembled, the dust collection frame 509 faces the workbench 2, so that the cleaning effect is achieved simultaneously when operating on the surface of the workbench 2. Finally, put the tools and remaining spare parts back into the drawer 401 and the shelf 403, close the cabinet door 402, push the device back to the storage area, and tidy up after the work is completed.

[0035] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
