The in-place assembly drawer effectively facilitates the replacement and regular maintenance of the oil mist separation filter cartridge without affecting the internal sealing. Combined with the setting of the maintenance cover, it is beneficial to extend the overall service life. The matching plug-in structure of the filter carrier plate arranged inside the dust removal filter chamber can appropriately adjust the installation spacing and installation quantity of the filter carrier plate in the dust removal filter chamber according to specific usage requirements, thereby effectively improving the overall gas impurity removal and filtration effect of the device. At the same time, through the docking association structure of the additional magnetic association shaft body, the magnetic connection between the shaft bodies can be used to perform stable transmission operations with each other, thereby realizing the centrifugal oil mist separation effect, effectively expanding the overall scope of application and correspondingly improving the overall comprehensive performance.

Installing different structures outside the energy-saving vacuum pump can provide different filtering effects for the energy-saving vacuum pump;

[0055] Step 3: Post-filter installation, the filter device is installed between the docking sleeve 30 on one side of the oil mist separation chamber 2 and the outlet end of the energy-saving pump. The adjustable assembly structure of the docking sleeve 30 itself is used to ensure that the filter device can be stably aligned and fastened with the outlet ends of different types of energy-saving pumps. It can also ensure that the outlet end of the energy-saving pump and the inside of the filter bearing housing 1 are connected to each other under the associated structure of the connecting transition duct 4, and the output end of the vacuum pump is stably docked with the working target, ensuring that it can perform stable and continuous pre-filtering operations under normal use of the vacuum pump;

[0056] Step 4: Pre-filtration operation. When the vacuum pump performs normal operation on the target container, the extracted gas first passes through the oil mist separation chamber 2, and then passes through the dust removal filter chamber 3 for dual filtration of oil mist separation and gas dust removal, and finally is discharged from the outlet end of the vacuum pump;

[0057] Step 5: Post-filtration operation. When the vacuum pump performs normal operation on the target container, the extracted gas is discharged from the output end of the vacuum pump to the outlet end. The exhaust gas first passes through the oil mist separation chamber 2 for oil mist separation under centrifugal action, and then passes through the dust removal filter chamber 3 for gas dust removal filtering operation, thereby completing the vacuum extraction operation and filtering work of the energy-saving vacuum pump;

By adding an associated mesh plate 18 and combining the structural characteristics of the perforated partition plate 16, the device can ensure the interconnection between the oil mist separation chamber 2 and the dust removal filter chamber 3 inside the filter bearing shell 1 on the basis of having a pull-out structure of the aligned assembly drawer 10, and the matching structure between the positioning sealing strip 20 and the sealing groove 15 helps to improve the internal sealing of the aligned assembly drawer 10 and the oil mist separation chamber 2 after assembly, effectively improving the device In order to improve the filtering smoothness of the vacuum pump, by adding a positioning receiving electromagnetic shaft 22, a positioning associated magnetic shaft 25 and a transmission electromagnetic shaft 41, and combining the electrical connection relationship between the electromagnetic control component 9 and the positioning receiving electromagnetic shaft 22 and the transmission electromagnetic shaft 41, the positioning receiving electromagnetic shaft 22, the positioning associated magnetic shaft 25 and the transmission electromagnetic shaft 41 can realize a transmission structure of alignment association with each other through magnetic adsorption.

By adopting a three-jaw chuck structure for the clamping block 35 in the docking sleeve 30, the clamping block 35 can drive the anti-slip clamp plate 37 to stably and tightly clamp the tubular port to be docked, thereby effectively expanding the scope of application of the device, allowing the device to perform stable docking operations with vacuum pumps of various specifications.

[0062] Example 4

[0063] The filter device of the energy-saving vacuum pump is assembled in a symmetrical manner and connected to the energy-saving vacuum pump in a stable symmetrical manner according to the required filtering conditions, specifically pre-filtration and post-filtration. Different installation structures outside the vacuum pump can provide different filtering effects for the energy-saving vacuum pump. For the pre-filtration installation, the filter device is installed in a symmetrical manner between the docking sleeve 30 on one side of the dust removal filter chamber 3 and the output end of the energy-saving pump. The adjustable assembly structure of the docking sleeve 30 itself is used to enable the filter device to be stably symmetrically associated and fastened to the output ends of energy-saving pumps of different models. Specifically, the rotating worm 31 is rotated to drive the clamping transmission disk 34 to rotate, so that the clamping block 35 is clamped inwardly, so that the anti-slip clamp plate 37 can stably clamp the docked end. The clamping assembly can also ensure that the outlet end of the energy-saving pump is connected to the inside of the filter bearing shell 1 under the associated structure of the connecting transition duct 4, and stably dock with the working target through the docking sleeve 30 on one side of the oil mist separation chamber 2, ensuring that it can perform stable and continuous post-filtration operations under normal use of the vacuum pump. For post-filtration installation, the filter device is aligned and installed between the outlet end of the energy-saving pump through the docking sleeve 30 on one side of the oil mist separation chamber 2, and the adjustable assembly structure of the docking sleeve 30 itself is used to enable the filter device to be stably aligned and fastened with the outlet ends of energy-saving pumps of different models, specifically, the rotating worm 31 is rotated to drive the clamping transmission disk 34 to rotate, so that the clamping block 35 is inward. The parts are clamped together, so that the anti-slip clamp plate 37 can stably clamp and assemble the docking end, and can also ensure that the energy-saving pump outlet end and the inside of the filter bearing shell 1 are connected to each other under the associated structure of the connecting transition duct 4, and the output end of the vacuum pump is stably docked with the working target, ensuring that it can perform stable and continuous pre-filtration operations under the normal use of the vacuum pump. During the pre-filtration operation, when the vacuum pump performs normal operation on the target container, the extracted gas first passes through the oil mist separation chamber 2, and under the driving action of the centrifugal drive motor 5, the rotating transmission disk 40 is driven to rotate through the transmission worm 39, and under the action of the electromagnetic association structure between the transmission electromagnetic shaft 41, the positioning receiving electromagnetic shaft 22 and the positioning associated magnetic shaft 25, the oil in the alignment assembly drawer 10 is driven. The mist separation filter cartridge 24 rotates to generate centrifugal force, thereby achieving the oil mist separation effect, and then passes through the dust removal filter chamber 3 to remove impurities from the multi-stage filter carrier plate 28 to achieve a double filtering effect, and finally discharges from the outlet end of the vacuum pump, and performs post-filtration. When the vacuum pump operates normally on the target container, the extracted gas is discharged from the output end of the vacuum pump to the outlet end, and the exhausted gas preferentially passes through the oil mist separation chamber 2. Under the driving action of the centrifugal drive motor 5, the rotating transmission disk 40 is driven to rotate through the transmission worm 39, and under the action of the electromagnetic correlation structure between the transmission electromagnetic shaft 41, the positioning receiving electromagnetic shaft 22 and the positioning associated magnetic shaft 25, the oil mist separation filter cartridge 24 in the alignment assembly drawer 10 is driven to rotate to generate centrifugal force.Thus, the oil mist separation effect is achieved, and then the gas impurity removal operation is carried out from the multi-stage filter carrier plate 28 through the dust removal filter chamber 3. During the filtering process, the ultrasonic generator 8 can be started to separate the dust on the filter carrier plate 28 from the filter carrier plate 28 and fall into the dust collecting bin 6. The dust in the dust collecting bin 6 can be cleaned by opening the dust cleaning door 12. After the work is completed, the pull-out structure of the drawer 10 and the inspection and assembly structure of the inspection cover 11 can be aligned to ensure that the filter device can be regularly inspected and maintained under long-term use to extend the service life of the entire filter device. The optimization of the overall structure effectively enriches the overall use effect of the device, and correspondingly improves the overall comprehensive performance, and the overall scope of application has been greatly expanded.
