Description

Technical Field

[0001] The invention relates to the technical field of blade cleaning, and in particular to a cleaning device for dirt accumulated on the surface of a molecular pump blade. Background Art

[0002] A molecular pump is a vacuum pump that uses a high-speed rotating rotor to transfer momentum to gas molecules, allowing them to obtain a directional speed and be compressed and driven toward the exhaust port. The molecular pump is mainly composed of two parts: a stator and a rotor. The stator is the stationary part of the molecular pump, usually composed of multiple semi-disc blades, and the rotor is the rotating part of the molecular pump.

[0003] However, in the prior art, when the molecular pump is extracting gas, the dust contained in the gas is polluted, and the molecular pump rotor blades are always rotating, causing most of the dust to accumulate on the stator blades, causing the blades to wear or clog. When a malfunction occurs, the stator blades will be removed and professionals will come to perform maintenance or send them to the manufacturer for maintenance. Some manufacturers will clean the molecular pumps when they receive them, and the cleaning method of the molecular pump blades mainly relies on manual flushing. After manually removing the protective shell outside the molecular pump, multiple stators that are assembled together are gradually removed, and the stators are placed in a water pool for unified cleaning, followed by continued drying, and the rotor is simply rinsed. Finally, the stator and rotor are manually assembled. This method is not only cumbersome to operate, but also time-consuming and labor-intensive. At the same time, it requires extremely high requirements for manual hands and workbenches, which increases the complexity of the operation, makes it difficult to completely avoid pollution, and multiple stators are operated together. Cleaning will cause the pollutants cleaned to affect each other. Another common cleaning method is to directly use a strong fan to blow the blades, but this method has poor sealing. At the same time, the wind blows directly to the stator, and the dust on the ground is easily splashed by the cleaning liquid, causing secondary pollution. In addition, since the stator blades are twisted and dense, simple wind cleaning and water flushing are not effective enough. Both methods require multiple cleanings, and attention should be paid to cleaning space hygiene to achieve a thorough cleaning effect. In order to solve these problems, some manufacturers will choose high-pressure water guns to effectively remove dirt and impurities on the blades, but this method will cause the stator to deform if used repeatedly, especially for molecular pumps that have been used for a long time. Repeated cleaning with high-pressure water guns will cause the stator to bend and easily collide with the rotor, causing serious damage to the equipment. Another method is to use automatic spraying, which is not only time-consuming, but also still cannot completely clean the densely arranged stators.

[0004] To this end, a cleaning device for dirt accumulated on the surface of molecular pump blades is proposed to ensure that the molecular pump blades are completely cleaned in a sealed and sanitary environment. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figure 1-Figure 9, as an embodiment of the present invention, a cleaning device for accumulated dirt on the surface of molecular pump blades is provided, including a water tank seat 1, a closed shell 2 arranged on the top of the water tank seat 1, a top shell 3 clamped on the top of the closed shell 2, a cleaning unit 4 arranged on one side of the water tank seat 1, a two-way roller 5 rotatably connected to the inside of the closed shell 2, two transmission rods 6 provided and slidably connected to the outside of the two-way roller 5, a linkage rod 7 slidably connected to the inside of the transmission rod 6, a telescopic frame 8 slidably connected to the inside of the linkage rod 7, an extrusion piece 9 located below the telescopic frame 8 and slidably connected to the inside of the water tank seat 1, an electromagnet 10 arranged on one side of the telescopic frame 8, two rotating shafts 11 respectively located on both sides of the top of the electromagnet 10, a limiting torsion spring 12 connected between the rotating shaft 11 and the telescopic frame 8, a wire shell 13 fixedly connected to the top of the linkage rod 7, and two and located inside the water tank seat 1. The support frame 14 and the pump body 15 fixedly connected to the inside of the support frame 14, the sliding directions of the linkage rod 7 and the telescopic frame 8 are perpendicular, the two transmission rods 6 and the support frame 14 are symmetrical about the central axis of the water tank seat 1, the top end of the wire shell 13 is slidably connected to the inside of the water tank seat 1, the support frame 14 is located between the two electromagnets 10, the pump body 15 includes a motor rotor 151 fixedly connected between the two support frames 14, and a stator 152 sleeved on the outside of the bottom of the motor rotor 151, the electromagnet 10 is used to adsorb the stator 152, and the cleaning unit 4 is used to clean the motor rotor 151 and the stator 152. At the same time, the cleaning unit 4 drives the motor rotor 151 to swing through the extrusion piece 9, and the stator 152 is completely cleaned in a sealed and sanitary environment, and then automatically assembled and completely sealed, which effectively improves the cleaning efficiency and quality and reduces the risk of pollution.

[0034] Among them, two transmission rods 6 are provided, so the positions and quantities of the linkage rod 7, telescopic frame 8, electromagnet 10, rotating shaft 11, limiting torsion spring 12 and wire housing 13 connected thereto correspond to the transmission rod 6, and the water tank seat 1 and the closed shell 2 are both provided with conventional interconnecting ports for circulation of the cleaning liquid.

[0035] In addition, the washable pump body 15 has a weight range of only 7.8 kg to 25 kg, and is cleaned for small and medium-sized pump bodies 15, such as JFB-600. The smaller pump body 15 has a smaller stator 152, which is easy to clean, while the large pump body 15 has a higher transportation and handling cost and is handled manually.

[0036] Reference Figure 1-Figure 5A dryer 21 and a drive motor 22 are fixedly arranged on the outside of the closed shell 2, and the output end of the drive motor 22 is fixedly connected to the bidirectional roller 5. An opening and closing door 23 is slidably connected to one side of the closed shell 2. Two guide slots 24 are arranged on the top of the closed shell 2. The two guide slots 24 are symmetrical about the central axis of the water tank seat 1. A section of the guide slot 24 close to the pump body 15 is a straight section 241. The opening and closing door 23 seals the closed shell 2 to reduce the contact of the operator.

[0037] Specifically, when the motor rotor 151 is separated from the stator 152, the electromagnet 10 needs to drive the stator 152 to completely separate from the motor rotor 151 so that the electromagnet 10 can move tiltedly, otherwise the stator 152 will collide with the motor rotor 151, and the closed shell 2 limits the wire shell 13, which can affect the moving path of the electromagnet 10, and then use the straight section 241 of the closed shell 2 to make the electromagnet 10 drive the stator 152 to move in a straight line, so that the motor rotor 151 and the stator 152 are completely separated.

[0038] Reference Figure 1-Figure 7 The transmission rod 6 is provided with a straight slot 61, and a sliding sleeve 71 is provided on the side of the linkage rod 7 close to the transmission rod 6. The sliding sleeve 71 is slidably connected to the inside of the straight slot 61, and a limit strip 201 is provided inside the closed shell 2. One end of the transmission rod 6 is slidably connected to the bidirectional roller 5, and the other end of the transmission rod 6 is slidably connected to the outside of the limit strip 201.

[0039] The telescopic frame 8 includes a support rod 81 arranged on one side of the linkage rod 7, two return springs 82 respectively located at both ends of the support rod 81, and two stabilizing rods 83 connected between the support rod 81 and the linkage rod 7. The return spring 82 is slidably connected to the inside of the linkage rod 7. The support rod 81 does not contact the electromagnet 10. The side of the electromagnet 10 away from the support rod 81 is an inwardly inclined arc surface, so that the contact area between the electromagnet 10 and the stator 152 is larger, and the adsorption force of the electromagnet 10 on the stator 152 is stronger. Even if the sizes are different, the arc surface can have a larger contact area with the center of the circle, further improving the stability of the adsorption effect.

[0040] Specifically, after the electromagnet 10 contacts the stator 152, it will be blocked and unable to move. At this time, the electromagnet 10 can squeeze the return spring 82 and the stabilizing rod 83, so that it can adaptively adjust when facing pump bodies 15 of different sizes. The adjustable range is the compressible limit of the return spring 82. There is no need to control the equipment, so that the bidirectional roller 5 always drives the transmission rod 6 to the same point after being driven. The electromagnet 10 will squeeze the support rod 81 to automatically adjust, and no adjustment is needed, thereby coping with pump bodies 15 of various sizes.

[0041] Among them, if an error occurs when manually combining the pump body 15 and the support frame 14, that is, the electromagnet 10 will contact and adsorb with the motor rotor 151, at this time, the electromagnet 10 and the motor rotor 151 can still be separated by using the return driving force of the two-way roller 5. However, when installing the pump body 15, the stator 152 needs to be placed within the height range of the electromagnet 10 at all times, and a height mark of the electromagnet 10 is provided on the outside of the closed shell 2 near the support frame 14 for easy viewing.

[0042] Reference Figure 2-Figure 5 The cleaning unit 4 includes a circulation pump 41 arranged on one side of the water tank seat 1, and a first pipeline 42 and a second pipeline 43 connected between the circulation pump 41 and the closed shell 2. The circulation pump 41 is fixedly connected to the water tank seat 1 and is a conventional water delivery device.

[0043] Reference Figure 2-Figure 6 A first nozzle 421 is provided on both sides of the top of the first pipeline 42. When the wire housing 13 is located in the guide slot 24 at the end away from the pump body 15, the center line of the first nozzle 421 coincides with the center line of the corresponding transmission rod 6. A second nozzle 422 and a third nozzle 423 are provided on the first pipeline 42. The second nozzle 422 is located above the third nozzle 423. The outside of the third nozzle 423 is connected with a bellows 401.

[0044] The corrugated shape of the bellows 401 will increase the flow resistance of the fluid. When the fluid passes through the bellows 401, the flow velocity changes due to the presence of the corrugations, thereby affecting the flow impact force.

[0045] Two vertical nozzles 431 are provided at the top of the second pipeline 43 , and the vertical nozzles 431 are located above the transmission rod 6 . After the electromagnet 10 adsorbs the stator 152 , the corresponding stator 152 can be flushed. The vertical nozzles 431 , the first nozzle 421 , and the second nozzle 422 are all provided with diversion nozzles 18 .

[0046] Specifically, the diverter nozzle 18 is a conventional method, and the diverter nozzle 18 is used to disperse the sprayed cleaning liquid, thereby expanding the flushing area.

[0047] Reference Figure 1-Figure 8 A compressed arc block 101 is provided at the bottom end of the electromagnet 10, and the extrusion member 9 includes a force-bearing rod 91 slidably connected to the inside of the water tank seat 1, and is provided with two arc-shaped pressing blocks 92 located at the top of the force-bearing rod 91, and a return spring 93 connected between the arc-shaped pressing block 92 and the water tank seat 1. The middle part of the force-bearing rod 91 is an arc surface 911, and the arc surface 911 is located at the water outlet of the bellows 401. When the wire housing 13 is located in the guide slot 24 away from the end point of the pump body 15, the arc-shaped pressing block 92 is located on one side of the compressed arc block 101.

[0048] A convex strip is arranged inside the sealing shell 2 and is located inside the force-bearing rod 91 to limit the force-bearing rod 91 .

[0049] Specifically, the arc surface 911 will be pushed when it is impacted by the cleaning liquid, and the cleaning liquid fluctuation output by the bellows 401 changes at a fixed frequency, so that the arc surface 911 is impacted back and forth, and the interior of the force-bearing rod 91 is restricted by the closed shell 2, so that the force-bearing rod 91 moves in a straight line, and the force-bearing rod 91 will drive the arc pressure block 92 to squeeze the pressure arc block 101, so that the electromagnet 10 rotates, and when the electromagnet 10 rotates, it will also drive the adsorbed stator 152 to rotate, and the bottom of the stator 152 will then tilt up, and at the same time cooperate with the first nozzle 421 and the vertical nozzle 431, so that when the cleaning liquid is sprayed from the first nozzle 421 and the vertical nozzle 431, different positions of the stator 152 can be fully cleaned, thereby avoiding excessive accumulation of cleaning liquid at a certain position, resulting in incomplete cleaning.

[0050] Reference Figure 1-Figure 9 Two power supplies 16 and a gathering shaft 17 are symmetrically arranged on the top of the water tank seat 1. The wire shell 13 is electrically connected to the electromagnet 10. The top of the wire shell 13 is a wiring sleeve 131, and the wiring sleeve 131 passes through the guide slot 24. Since the electromagnet 10 will be compressed and stop moving when it contacts the stator 152, the wire shell 13 will also move with the transmission rod 6 at this time. In order to prevent the wire shell 13 from contacting the support frame 14, the return spring 82 is made to have a length of the wire shell 13 that is less than the spacing between the support rod 81 and the linkage rod 7 when it is not deformed, so that the length of the wire shell 13 will never contact the support frame 14.

[0051] Specifically, the output end of the power supply 16 can be connected to a wire, which is wound around the outside of the gathering shaft 17 and is also connected to the wiring sleeve 131. The power supply 16 can provide power to the wire shell 13. When the wiring sleeve 131 moves, the distance between the wiring sleeve 131 and the power supply 16 changes. At this time, the gathering shaft 17 can automatically gather or release the guide. The gathering shaft 17 is a conventional wire-collecting structure composed of a torsion spring and a sleeve to ensure stable power supply.

[0052] Reference Figure 1-Figure 9, support blocks 811 are provided on both sides of the top of the support rod 81, and two rotating shafts 11 pass through the corresponding support blocks 811, and the two rotating shafts 11 are supported by the support blocks 811, and at the same time, two limiting torsion springs 12 are used to fix the electromagnet 10 on one side of the support rod 81, and a stabilizing sleeve 812 is provided at the bottom of the support rod 81, and the stabilizing sleeve 812 is used to support the bottom of the electromagnet 10. At the same time, silicone is provided on the contact surface between the stabilizing sleeve 812 and the electromagnet 10 to avoid large friction damage between the electromagnet 10 and the stabilizing sleeve 812 during reciprocating rotation. That is, the arc pressure block 92 will squeeze the compressed arc block 101. At this time, the bottom of the compressed arc block 101 is tilted, and the stabilizing sleeve 812 is not released from the electromagnet 10. When the compressed arc block 101 does not contact the arc pressure block 92, the arc pressure block 92 does not squeeze the compressed arc block 101, and the stabilizing sleeve 812 fits the electromagnet 10.

[0053] Reference Figure 1-Figure 9 The support frame 14 includes a fixing frame 141 fixedly connected to the water tank seat 1, and a split frame 142 clamped on the top of the fixing frame 141, the motor rotor 151 is located between the two split frames 142, the split frame 142 is located above the stator 152, and the electromagnet 10 is located below the split frame 142, so as to avoid the electromagnet 10 from contacting the split frame 142, and fully utilize the electromagnet 10 to adsorb the stator 152, and in order to ensure that different types of pump bodies 15 are located between the two electromagnets 10, the fixing frame 141 and The splicing frame 142 is symmetrical about the central axis of the water tank seat 1. At this time, for different types of pump bodies 15, two splicing frames 142 are used to fix them above the motor rotor 151, and then the splicing frame 142 and the fixing frame 141 are fixed. Different sizes of splicing frames 142 are required for different types of pump bodies 15, that is, after the two splicing frames 142 are combined, the middle part is circular, and the center of the circle is always maintained at the same center, so that different pump bodies 15 can be located at the same position, ensuring that the electromagnet 10 accurately adsorbs the stator 152.

[0054] In addition, the split frame 142 is usually equipped with a pump body 15 of conventional model standard parts, such as JFB-600.

[0055] The working principle of the present invention is as follows: the bidirectional roller 5 is driven to rotate by the driving motor 22, so that the bidirectional roller 5 drives the two transmission rods 6 to move toward the position of the motor rotor 151 at the same time, and the transmission rod 6 will drive the connected parts to move synchronously when moving, that is, the linkage rod 7, the telescopic frame 8, the electromagnet 10, the rotating shaft 11, the limit torsion spring 12 and the wire housing 13 will also move synchronously therewith, and when the transmission rod 6 drives the linkage rod 7 to move, since the top of the linkage rod 7 is fixedly connected to the top of the wire housing 13 and is located inside the guide slot 24, the wire housing 13 is restricted by the path of the guide slot 24, and when the transmission rod 6 drives the linkage rod 7, the wire housing 13 moves along the path of the guide slot 24, and the wire housing 13 will drive the linkage rod 7 synchronously The linkage rod 7 moves, and the sliding sleeve 71 arranged on one side of the linkage rod 7 is located inside the straight slot 61, so that the linkage rod 7 is restricted by the two paths of the straight slot 61 and the guide slot 24, and then the linkage rod 7 drives the telescopic frame 8 to move as a whole, and the telescopic frame 8 will drive the electromagnet 10, the rotating shaft 11 and the limiting torsion spring 12 to move synchronously with the linkage rod 7. When the electromagnet 10 contacts the stator 152, the driving motor 22 will continue to drive the transmission rod 6 to move through the two-way roller 5. At this time, the electromagnet 10 will also move synchronously, but at this time the arc surface of the electromagnet 10 contacts the stator 152, and the stator 152 blocks the electromagnet 10. The electromagnet 10 will squeeze the support rod 81 through the rotating shaft 11, and the support rod 81 will then compress the return spring 82, and the stabilizing rod 83 will also Then it slides inside the linkage rod 7, and then the power supply 16 supplies power to the wire housing 13, so that the wire housing 13 supplies power to the electromagnet 10, so that the electromagnet 10 absorbs the stator 152, and then the motor 22 drives the two-way roller 5 to make the transmission rod 6 move back, and the electromagnet 10 absorbs the stator 152 and moves back, so that the stator 152 is separated from the motor rotor 151. At this time, the return spring 82 will gradually rebound first, and then the electromagnet 10 will gradually reset with the transmission rod 6, so that the motor rotor 151 and the two stators 152 are respectively located at different positions, and the two stators 152 are separated by the closed shell 2 to form different spaces. At this time, the water inside the water tank seat 1 is transported to the first pipeline 42 and the second pipeline 43 through the circulating pump 41, and the cleaning liquid passes through the first pipeline 42 and the second pipeline 43. The second nozzle 422 of the pipeline 42 simply flushes the motor rotor 151, and at the same time, the cleaning liquid moves downward from the top of the electromagnet 10 through the vertical nozzle 431 of the second pipeline 43, so that the stator 152 adsorbed by the electromagnet 10 is flushed, and the cleaning liquid will flush the internal blades of the stator 152 from the first nozzle 421 of the first pipeline 42. At the same time, when the cleaning liquid reaches the bellows 401 at the third nozzle 423, the impact force of the cleaning liquid is affected by the bellows 401 and fluctuates. When the impact of the cleaning liquid is large, it pushes the arc surface 911 of the force-bearing rod 91, so that the force-bearing rod 91 drives the arc pressure block 92 to move to squeeze the compressed arc block 101, and at the same time, the reset spring 93 is stretched when the force-bearing rod 91 moves.After the compressed arc block 101 is squeezed, the electromagnet 10 rotates with the rotating shaft 11 as the fulcrum, and at the same time, the limit torsion spring 12 rotates and compresses. When the impact force is small, the reset spring 93 rebounds to drive the arc-shaped pressing block 92 and the force-bearing rod 91 to move back synchronously, so that the electromagnet 10 drives the stator 152 to rotate continuously and slightly, so that the cleaning liquid at two positions can completely rinse the stator 152. After rinsing for the set time, it is dried by the dryer 21, and then the driving motor 22 drives the bidirectional roller 5 to move the transmission rod 6 to drive the electromagnet 10. The electromagnet 10 assembles the stator 152 with the motor rotor 151, and then the driving motor 22 drives the transmission rod 6 to drive the corresponding components to move back, thereby completing the flushing.
