Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, and more particularly to a vacuum pump filtering assembly which is easy to disassemble. Background Art

[0002] A vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a closed space. Vacuum pumps can basically be divided into two types: gas capture pumps and gas transmission pumps. They are widely used in metallurgy, chemical industry, food, electronic coating and other industries.

[0003] When the operator uses a vacuum pump to evacuate the container, in order to prevent large particles from entering the vacuum pump and causing damage to the impeller of the vacuum pump, a filtering device is often installed at the inlet of the vacuum pump, so that the large particles can be absorbed and filtered, thereby ensuring the normal operation of the vacuum pump and extending the service life of the vacuum pump. The existing vacuum pump and the filtering device are often connected by multiple bolts. Although this method has basic connection functions, when the vacuum pump needs to be disassembled and assembled, the operator will need to manually unscrew multiple bolts in turn. The operation process is too cumbersome, which reduces the operating efficiency and brings inconvenience to the operator. Therefore, it needs to be improved. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1 to 7 As shown, the utility model provides a vacuum pump filter assembly that is easy to disassemble, including:

[0032] The vacuum pump body 1 has a short tube 2 fixedly mounted on the top of the left side of the vacuum pump body 1, a vertical tube 3 is movably sleeved inside the short tube 2, and a filter body 4 is fixedly sleeved on the outer surface of the top of the vertical tube 3;

[0033] A first round block 5, the interior of the first round block 5 is fixedly sleeved with the outer surface of the short tube 2, the top of the first round block 5 is movably connected to a first gasket 6, the outer surface of the first gasket 6 is fixedly sleeved with a second round block 7, and the interior of the second round block 7 is fixedly sleeved with the outer surface of the vertical tube 3;

[0034] The disassembly and assembly mechanism is arranged on the outer surface of the vertical pipe 3;

[0035] Among them, the disassembly and assembly mechanism includes a threaded sleeve 8, the interior of the threaded sleeve 8 is fixedly sleeved with the outer surface of the vertical tube 3, the outer surface of the threaded sleeve 8 is threadedly sleeved with a rotating ring 9, and the outer surface of the rotating ring 9 is movably sleeved with a circular ring 10. The outer surface of the circular ring 10 is fixedly installed with a vertical rod 11, and the outer surface of the other end of the vertical rod 11 is fixedly installed with a lifting ring 12. The outer surface of the lifting ring 12 is fixedly installed with a first hinge block 13, and the outer surface of the first hinge block 13 is hinged with a moving rod 14. The inner surface of the other end of the moving rod 14 is fixedly sleeved with an extrusion shaft 15, and the outer surface of the extrusion shaft 15 is movably sleeved with a rotating rod 16. The outer surface of the rotating rod 16 is movably connected to the inner movability of the moving rod 14. The outer surface of the bottom end of the rotating rod 16 is movably connected to the outer surface of the first round block 5, and the inner top of the rotating rod 16 is connected with a second hinge block 17. The other end of the second hinge block 17 is fixedly installed with a fixing ring 18, and the inner part of the fixing ring 18 is fixedly sleeved with the outer surface of the vertical tube 3.

[0036] Since the interior of the rotating ring 9 is threadedly engaged with the outer surface of the threaded sleeve 8, when the rotating ring 9 rotates, it will drive the circular ring 10 to move downward along the outer surface of the threaded sleeve 8. At this time, the circular ring 10 will drive the lifting ring 12 to move downward through the four vertical rods 11. At this time, the lifting ring 12 will drive the four moving rods 14 to move through the four first hinge blocks 13. Then the four moving rods 14 will squeeze and push the four rotating rods 16 through the four extrusion shafts 15, so that the four rotating rods 16 rotate with the four second hinge blocks 17 as the axis. At this time, the four rotating rods 16 will release contact with the first round block 5 during rotation, and the vertical tube 3 as a whole will be able to be taken out from the inside of the short tube 2.

[0037] The outer surface of the filter body 4 is provided with a long groove 19 , and the interior of the filter body 4 is provided with a short groove 20 .

[0038] Due to the design of the long slot 19 and the short slot 20, the object located therein is limited so that it can only move up and down.

[0039] The top of the filter body 4 is movably sleeved with a filter cover 21 , the bottom of the filter cover 21 is fixedly sleeved with a second gasket 22 , and the bottom of the second gasket 22 is movably connected to the top of the filter body 4 .

[0040] Due to the design of the second gasket 22 , the sealing between the filter body 4 and the filter cover 21 is enhanced.

[0041] The short slot 20 is internally movably connected to a vertical plate 24 , and a filter screen 25 is fixedly mounted on the outer surface of the vertical plate 24 . There are multiple groups of filter screens 25 , and the outer surfaces of the multiple groups of filter screens 25 are all movably connected to the inner surface of the filter body 4 .

[0042] Due to the design of the multiple groups of filter screens 25, large particles can be effectively filtered. Since the diameters of the mesh holes on the multiple groups of filter screens 25 are different, three-stage filtering of large particles can be achieved.

[0043] A fixing block 23 is fixedly mounted on the top of the vertical plate 24 , and an outer surface of the fixing block 23 is movably connected to the interior of the short slot 20 .

[0044] Due to the design of the four fixing blocks 23 , an operator can conveniently remove multiple groups of filter screens 25 from the interior of the filter body 4 through the four fixing blocks 23 .

[0045] The top of the fixed block 23 is movably connected to a square block 35 , and the top of the outer surface of the square block 35 is fixedly connected to the inner portion of the bottom end of the filter cover 21 .

[0046] Due to the design of the square block 35 , when the bottom end of the square block 35 contacts the top end of the fixing block 23 , multiple groups of filter screens 25 can be fixed.

[0047] A third hinge block 26 is fixedly mounted on the bottom end of the outer surface of the filter cover 21 , and a rotating block 27 is hingedly connected to the outer surface of the third hinge block 26 .

[0048] Since the third hinge block 26 is hinged to the rotating block 27 , the rotating block 27 can rotate around the hinge point with the third hinge block 26 as the axis.

[0049] Among them, the long groove 19 is internally movably connected to a lifting block 29, the outer surface of the other end of the lifting block 29 is internally movably connected to the rotating block 27, and the outer surface of the lifting block 29 is fixedly installed with a moving ring 28, and the interior of the moving ring 28 is movably connected to the outer surface of the filter body 4.

[0050] Due to the limiting effect of the long slot 19, the lifting block 29 can only move up and down. When the lifting block 29 moves downward, it will squeeze the inside of the rotating block 27, thereby fixing the connection between the entire filter cover 21 and the entire filter body 4.

[0051] Among them, a lifting plate 30 is fixedly installed on the outer surface of the moving ring 28, and a screw 31 is sleeved on the internal thread of the lifting plate 30. The bottom end of the screw 31 is movably sleeved on a fixing plate 32, and the back side of the fixing plate 32 is fixedly connected to the outer surface of the filter body 4.

[0052] Due to the design of the fixed plate 32, the screw 31 can only rotate in place. Since the outer surface of the screw 31 is engaged with the internal thread of the lifting plate 30, when the screw 31 rotates, it will drive the lifting plate 30 to move, and then the lifting plate 30 will drive the lifting block 29 to move downward through the moving ring 28.

[0053] A circular block 33 is fixedly mounted on the top of the screw rod 31 , a bottom end of the circular block 33 is movably connected to the top of the lifting plate 30 , and a twisting block 34 is fixedly mounted on the top of the circular block 33 .

[0054] Due to the design of the twisting block 34 , the operator can rotate the circular block 33 by twisting the twisting block 34 , and when the circular block 33 rotates, the screw rod 31 is also rotated.

[0055] The working principle and use process of this utility model:

[0056] When the operator needs to disassemble and assemble the filter body 4 and the vacuum pump body 1, the operator screws the rotating ring 9. Since the interior of the rotating ring 9 is threadedly sleeved with the outer surface of the threaded sleeve 8, the rotating ring 9 will move downward at the same time when it rotates along the outer surface of the threaded sleeve 8. Since the interior of the circular ring 10 is movably sleeved with the interior of the outer surface of the rotating ring 9, the circular ring 10 will move downward under the drive of the rotating ring 9. At the same time, the circular ring 10 will simultaneously drive the four vertical rods 11 to move downward. At this time, the lifting ring 12 will move downward along the outer surface of the vertical pipe 3 under the drive of the vertical rod 11, and then the four first hinge blocks 13 will move downward under the drive of the lifting ring 12. The four first hinge blocks 13 will drive the four moving rods 14 to move at the same time. At this time, the other ends of the four moving rods 14 will respectively drive the four extrusion shafts 15 to move. At this time, the outer surfaces of the four extrusion shafts 15 will squeeze and push the four rotating rods 16 during the movement. Since the inner parts of the top ends of the four rotating rods 16 are respectively hinged to the outer surfaces of the four second hinge blocks 17, the four rotating rods 16 will rotate with the hinges with the four second hinge blocks 17 as the axis under the drive of the four extrusion shafts 15. Then, the four rotating rods 16 will be disconnected from the first round block 5 during the rotation, so that the vertical pipe 3 as a whole can be taken out from the inside of the short tube 2, thereby realizing the function of facilitating the disassembly and assembly of the filter body 4.

[0057] When the operator needs to replace multiple groups of filter screens 25, the operator places multiple groups of square blocks 35 as a whole inside the filter body 4. At this time, the four vertical plates 24 will be respectively located inside the four short slots 20. Then the operator places the filter cover 21 as a whole on the top of the filter body 4. At this time, the interior of the bottom end of the filter cover 21 will be movably connected with the top end of the filter body 4. At the same time, the bottom ends of the four filter screens 25 will respectively contact the top ends of the four fixed blocks 23. At this time, the four square blocks 35 will fix the four fixed blocks 23 as a whole through the four fixed blocks 23. Then the operator rotates the two rotating blocks 27 with the two third hinge blocks 26 as the axis. Then the interior of the two rotating blocks 27 will rotate with the two lifting blocks. The outer surface of 29 is in contact with each other, and the operator screws the screwing block 34. At this time, the screwing block 34 will drive the screw 31 to rotate through the circular block 33. Since the outer surface of the screw 31 is engaged with the internal thread of the lifting plate 30, when the screw 31 rotates, it will drive the lifting plate 30 to move. Then the lifting plate 30 will drive the two lifting blocks 29 to move through the moving ring 28. Due to the design of the two long grooves 19, the movement of the two lifting blocks 29 will be limited so that it can only move up and down. At this time, the two lifting blocks 29 will move downward under the drive of the moving ring 28, and then the two lifting blocks 29 will squeeze and push the inside of the two rotating blocks 27 during the downward movement, thereby realizing the function of convenient replacement of the filter 25.
