[0029] See also Figure 1-5 A vacuum pump filtering device comprises a lower shell 1, an upper shell 2, an internal filtering mechanism, a quick loading and unloading mechanism and a loading and unloading auxiliary mechanism. The lower shell 1 and the upper shell 2 are connected to form a filtering space. The internal filtering mechanism comprises an inner fixed ring plate 3, a mounting seat 4, a lateral plate 5, a filter plate group 6 and a spiral filter screen 7. The inner fixed ring plate 3 is fixed on the inner wall of the lower shell 1. One end of the filter plate group 6 is provided with a mounting seat 4. The lateral plate 5 is arranged on the side of the mounting seat 4. The spiral filter screen 7 is installed on the upper shell 2. On the inner wall of the clamping tube 8, the quick disassembly mechanism includes a clamping tube 8, a clamping rod 9, a clamping groove 10, a clamping rod 11 and a rotating sleeve 12. The clamping rod 9 can be movably extended into the interior of the clamping tube 8. The clamping groove 10 is arranged on the side of the clamping rod 9. The rotating sleeve 12 penetrates the limit rotation and is connected to the side wall of the clamping tube 8. The inner wall of the rotating sleeve 12 is threadedly connected to the outer wall of the clamping rod 11, and the clamping rod 11 can be extended into the clamping groove 10 to fix the clamping rod 9. One end of the clamping rod 9 is fixedly connected to the inner fixed ring plate 3.

[0030] In this embodiment, when the vacuum pump starts to run, the operation of the internal filtering mechanism is required. The air enters the filtering space through the air inlet pipe 27 on the side of the upper shell 2. The air inlet channel composed of the air inlet pipe 27 and the spiral filter screen 7 guides the air to be evenly distributed on the spiral filter screen 7. The spiral structure promotes the rotation of the air while flowing inward, increases the contact area with the filter screen, and improves the filtering efficiency. The air first passes through the preliminary filtration of the spiral filter screen 7, and then passes through the filter group 6 for more detailed filtration to effectively remove particulate matter. The air that has passed through multiple stages of filtration enters the lower shell 1, and finally Finally, the filtered air is delivered to the air inlet of the pump by means of the mounting plate 28 installed at the outlet end of the lower shell 1 and the bolt fixing method, so that the filter group 6 can be quickly installed and disassembled. During the assembly process, the clamping rod 9 is inserted into the clamping tube 8, and the internal clamping rod 11 is extended into the clamping groove 10 by rotating the rotating sleeve 12 to fix the clamping rod 9 to achieve a quick and stable connection. During the disassembly process, the rotating sleeve 12 is rotated in the reverse direction to withdraw the clamping rod 11 from the clamping groove 10, and the clamping rod 9 can be taken out from the clamping tube 8 immediately, so as to achieve quick disassembly.

[0031] The loading and unloading auxiliary mechanism includes a base plate 13, a rotating tube 14, an internal gear 15, a rotating gear 16, a rotating rod 17, a first bevel gear 18 and a second bevel gear 19. The base plate 13 is fixedly arranged on the side wall of the clamping tube 8, the internal gear 15 is installed at one end of the rotating tube 14, the rotating gear 16 is meshed with the internal gear 15, one end of the rotating rod 17 extends through the base plate 13 and is connected with the rotating gear 16, the first bevel gear 18 is installed at one end of the rotating rod 17, and the first bevel gear 18 and the second bevel gear 19 are meshed, and the rotating sleeve 12 is matched with the second bevel gear 19.

[0032] By rotating the rotating rod 17, the internal gear 15 is driven to rotate, which drives the rotating gear 16 to rotate, and then drives the rotating rod 17 to rotate. This action is transmitted to the rotating sleeve 12 through the gear transmission mechanism. The rotation of the rotating sleeve 12 directly affects the locking and unlocking process of the quick loading and unloading mechanism. The meshing connection between the first bevel gear 18 and the second bevel gear 19 realizes the direction change and transmission of the rotational force, so that the operator can control the loading and unloading process more accurately.

[0034] More specifically, the design of the guide groove 25 and the guide block 26 realizes the precise guidance and position limitation of the clamping rod 9, ensuring the smooth and correct loading and unloading process. The air intake channel composed of the air intake pipe 27 and the spiral filter screen 7 effectively guides the air, ensuring the full utilization of the filter medium. The design of the mounting plate 28 at the outlet end of the lower shell 1 allows it to be stably connected to the air inlet of the pump by bolts, ensuring the stability and safety of the filtering device.

[0035] In summary, when the overall equipment is in use or running: when the vacuum pump starts running, the internal filtering mechanism needs to be operated, and the air enters the filtering space through the air inlet pipe 27 on the side of the upper shell 2. The air inlet channel composed of the air inlet pipe 27 and the spiral filter screen 7 guides the air to be evenly distributed on the spiral filter screen 7. The spiral structure promotes the air to rotate while flowing inward, increasing the contact area with the filter screen and improving the filtering efficiency. The air first passes through the spiral filter screen 7 for preliminary filtration, and then passes through the filter group 6 for more detailed filtration to effectively remove particulate matter. The air after multi-stage filtration enters the lower shell 1, and finally the filtered air is delivered to the air inlet of the pump through the mounting plate 28 installed at the outlet end of the lower shell 1 and fixed with bolts.

[0036] When the operation process of the quick loading and unloading mechanism is required, the filter set 6 can be quickly installed and disassembled. During the assembly process, the clamping rod 9 is inserted into the clamping tube 8. By rotating the rotating sleeve 12, the internal clamping rod 11 extends into the clamping groove 10 to fix the clamping rod 9 to achieve a quick and stable connection. During the disassembly process, the rotating sleeve 12 is rotated in the reverse direction to withdraw the clamping rod 11 from the clamping groove 10, and the clamping rod 9 can be taken out from the clamping tube 8 immediately, thereby achieving quick disassembly.

[0037] When the operation of the loading and unloading auxiliary mechanism is required, the rotating rod 17 is rotated to drive the rotation of the internal gear 15, which drives the rotation of the rotating gear 16, and then drives the rotation of the rotating rod 17. This action is transmitted to the rotating sleeve 12 through the gear transmission mechanism. The rotation of the rotating sleeve 12 directly affects the locking and unlocking process of the quick loading and unloading mechanism. The meshing connection between the first bevel gear 18 and the second bevel gear 19 realizes the direction change and transmission of the rotational force, so that the operator can control the loading and unloading process more accurately.

[0038] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
