Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a filtering component for welding oil particles of a vacuum pump in a group welding line. Background Art

[0002] The types of vacuum pumps are constantly enriched and developed. Mechanical vacuum pumps, such as rotary vane vacuum pumps, use the movement of mechanical components to change the volume inside the pump, thereby realizing gas extraction. At the same time, oil-sealed vacuum pumps improve the pumping performance and ultimate vacuum degree of the pump through the sealing effect of oil. In some fields with extremely high requirements for vacuum degree, such as semiconductor manufacturing and high-energy physics research, more advanced vacuum pump technologies, such as turbomolecular pumps and cryopumps, have gradually emerged. The performance of vacuum pumps has been continuously improved, including the increase in pumping speed, the improvement of ultimate vacuum degree, the enhancement of stability, and the expansion of adaptability to different gases.

[0003] Before the vacuum pump works, first close the suction valve and the exhaust valve, unscrew the side hole plug of the exhaust valve, install the exhaust pipe, open the side hole channel to discharge air, close the valve to the atmosphere in the system, open all other valves in the system, forcefully connect the contacts of the oil pressure controller and the low-pressure controller, start the compressor, and slowly open the suction valve after the oil pressure is normal. Place the energy regulating device in the lowest gear. The vacuum pumping should adopt the intermittent vacuum pumping method. When the compressor continuously pumps air until no air flow sound can be heard, immerse the exhaust pipe in the refrigerating oil cup and observe the bubbling situation at the pipe orifice. If no bubbles emerge within 5 minutes, it can be considered that the gas in the system has been basically pumped out.

[0004] Vacuum pumps are involved in many industries, such as vacuum impregnation and vacuum casting processes in industrial production. The vacuum pump is in a high-temperature environment with relatively large particles and a lot of dust, and the vacuum pump will generate welding oil particles during operation. These particles themselves have a certain viscosity, and the particles will adhere to each other or attach to other particles. Moreover, these dust particles and welding oil particles will enter the interior of the vacuum pump through the air inlet of the vacuum pump, which is likely to cause damage to the motor. Especially when the welding oil enters the internal reduction gearbox before the motor and solidifies, it will cause the gear to jam, seriously affecting the stability of the vacuum environment and the welding quality. Summary of the Utility Model

[0005] In view of the problem that the above-mentioned dust particles and welding oil particles will enter the interior of the vacuum pump through the air inlet of the vacuum pump and are likely to cause damage to the motor, the present utility model is proposed.

[0006] To solve the above technical problems, the present utility model provides the following technical solutions: a filtering component for solder oil particles of a group welding line vacuum pump. The filtering component for solder oil particles of the group welding line vacuum pump includes: a rectangular mounting plate and a vacuum pump main body. The vacuum pump main body is temporarily fixed on the upper surface of the rectangular mounting plate. A rectangular sleeve is further provided on the upper surface of the vacuum pump main body, and a cylindrical barrel is arranged inside the rectangular sleeve. An annular sleeve is arranged inside the cylindrical barrel, and spiral blades are fixedly connected to the outer arc surface of the annular sleeve. A buffer screen is arranged directly below the annular sleeve. An installation ring is arranged directly above the cylindrical barrel, and a conical sleeve is temporarily fixed on the upper surface of the installation ring. A filter screen penetrates through the arc surface of the conical sleeve. An activated carbon storage box is arranged directly above the installation ring.

[0007] As a preferred scheme of the filtering component for solder oil particles of the group welding line vacuum pump of the present utility model, wherein: a processing box is arranged on one side of the rectangular sleeve. A humidifier is installed on the upper surface of the processing box, and a connecting plate is further arranged on the lower surface of the processing box.

[0008] As a preferred scheme of the filtering component for solder oil particles of the group welding line vacuum pump of the present utility model, wherein: an installation sleeve is further arranged inside the cylindrical barrel, and several cylindrical rods are arranged on the upper surface of the installation sleeve. The upper surfaces of the cylindrical rods are all connected to the same annular sleeve. A circular pipe is communicated with the upper surface of the annular sleeve, and the circular pipe also penetrates through the cylindrical barrel and extends directly above the cylindrical barrel.

[0009] As a preferred scheme of the filtering component for solder oil particles of the group welding line vacuum pump of the present utility model, wherein: a dust blocking net is slidably connected inside the activated carbon storage box, and a hole blocking net is penetrated through the bottom surface inside the activated carbon storage box. A pair of symmetrical guiding blocks are arranged on the vertical surface of the dust blocking net. A rectangular baffle is arranged on one of the vertical surfaces of the activated carbon storage box.

[0010] As a preferred scheme of the filtering component for solder oil particles of the group welding line vacuum pump of the present utility model, wherein: an air delivery pump is arranged on the vertical surface outside the rectangular sleeve, and a docking pipe penetrates through and communicates with the upper surface of the vacuum pump main body.

[0011] As a preferred scheme of the filtering component for solder oil particles of the group welding line vacuum pump of the present utility model, wherein: a connecting pipe is arranged on the air delivery pump. One end of the connecting pipe penetrates through and communicates with the rectangular sleeve, and the other end of the connecting pipe is connected to the docking pipe.

[0012] The beneficial effects of the present utility model:

[0013] 1. According to the environment in the factory, the device adopts a multi - filtration method. Through the cooperation of the spiral structure inside the cylindrical barrel and the conical sleeve, dust and particles mixed with the welding oil can be filtered out and accumulated at the bottom of the rectangular sleeve for unified treatment. Moreover, the device is also provided with a structure for dealing with welding oil. Since welding oil is insoluble in water, and the activated carbon inside the activated carbon storage box has good adsorption performance, it can adsorb welding oil particles in the air. Combining the above - mentioned multi - stage filtration technology, welding oil particles can be effectively intercepted while ensuring smooth gas flow and not affecting the working efficiency of the vacuum pump.

[0014] 2. As known from the activated carbon in beneficial effect 1, the absorption of activated carbon is limited, so it can only be replaced after being used for a period of time. There is a rectangular baffle at the vertical surface of the activated carbon storage box. A pair of installation holes are opened at the vertical surface of the rectangular baffle. The rectangular baffle and the rectangular sleeve are temporarily fixed by screws. The screw fixation is convenient and the structure is simple, without wasting time when replacing the activated carbon. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the above-mentioned purposes, 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.

[0024] Example 1

[0025] Reference Figure 1-4 6 is the first embodiment of the utility model, which provides a filtering component for welding oil particles of a welding line vacuum pump, including: a rectangular mounting plate 1 and a vacuum pump body 2, the vacuum pump body 2 is temporarily fixed on the upper surface of the rectangular mounting plate 1, and a driving component is also arranged on the upper surface of the rectangular mounting plate 1, a rectangular sleeve 3 is also arranged on the upper surface of the vacuum pump body 2, and a cylindrical tube 4 is arranged inside the rectangular sleeve 3, and a mounting plate is arranged at the vertical surface inside the rectangular sleeve 3, the rectangular sleeve 3 and the cylindrical tube 4 are temporarily fixed by the mounting plate, a circular ring sleeve 6 is arranged inside the cylindrical tube 4, the circular ring sleeve 6 is hollow, connecting the two ends of the circular ring sleeve 6, and a spiral blade 7 is fixedly connected to the arc surface outside the circular ring sleeve 6, and the spiral blade 7 is not in contact with the inside of the cylindrical tube 4, and a gap is left between the spiral blade 7 and the inner wall of the cylindrical tube 4, a buffer net 8 is arranged directly below the circular ring sleeve 6, a mounting ring 9 is arranged directly above the cylindrical tube 4, and a conical sleeve 10 is temporarily fixed on the upper surface of the mounting ring 9.

[0026] The filter screen 11 is connected through the curved surface of the conical sleeve 10 , and the filter screen 11 is only arranged on the inclined surface of the conical sleeve 10 . An activated carbon storage box 12 is arranged just above the mounting ring 9 , and a plurality of air inlets are arranged at the bottom of the activated carbon storage box 12 , so that air can enter the interior of the activated carbon storage box 12 .

[0027] A processing box 13 is provided on one side of the rectangular sleeve 3, and a humidifier 14 is installed on the upper surface of the processing box 13. The working principle and characteristics of the humidifier 14 are cited in the text: Working principle of mini humidifier, and a connecting plate is also provided on the lower surface of the processing box 13.

[0028] Inside the cylindrical barrel 4, there is also an installation sleeve 15. At the upper surface of the installation sleeve 15, there are also several cylindrical rods 16. At the upper surfaces of the cylindrical rods 16, the same ring sleeve 6 is connected. At the upper surface of the ring sleeve 6, a circular pipe 17 is communicated. The circular pipe 17 also penetrates through the cylindrical barrel 4 and extends directly above the cylindrical barrel 4. At the upper surface of the cylindrical barrel 4, an L-shaped air delivery pipe is penetrated and communicated, and the L-shaped air delivery pipe is also communicated with the processing box 13.

[0029] At the vertical surface outside the rectangular sleeve 3, there is also an air delivery pump 20. At the upper surface of the vacuum pump main body 2, a docking pipe 21 is penetrated and communicated. On the air delivery pump 20, there is also a connecting pipe 22. One end of the connecting pipe 22 penetrates through and communicates with the rectangular sleeve 3, and the other end of the connecting pipe 22 is connected to the docking pipe 21.

[0030] During use, first start the air delivery pump 20. Because there is also a connecting pipe 22 on the air delivery pump 20, one end of the connecting pipe 22 penetrates through and communicates with the rectangular sleeve 3, and the other end of the connecting pipe 22 is connected to the docking pipe 21. Driven by the air delivery pump 20, air will first enter the inside of the processing box 13, and then start the humidifier 14 installed on the upper surface of the processing box 13. With the start of the humidifier 14, the atomized moisture will come into contact with the dust particles and impurities in the air;

[0031] Then it enters the inside of the cylindrical barrel 4 through the L-shaped air delivery pipe. Because there is a ring sleeve 6 inside the cylindrical barrel 4, the ring sleeve 6 is hollow, and both ends are communicated. And on the outer arc surface of the ring sleeve 6, a spiral blade 7 is fixedly connected. And the spiral blade 7 does not fit the inside of the cylindrical barrel 4, and there is a gap between the spiral blade 7 and the inner wall of the cylindrical barrel 4. At this time, the particles in the air are in a humidified state, and the dry and wet degrees of each particle are different. For the relatively wet particles, when rotating on the spiral blade 7, the centrifugal force generated will throw them on the inner wall of the cylindrical barrel 4, and then will leave along the inner wall of the cylindrical barrel 4, thus accumulating inside the rectangular sleeve 3;

[0032] And the relatively dry particles will enter directly above the cylindrical barrel 4 through the ring sleeve 6. Then the dry particles will contact the filter screen 11 on the inclined surface of the conical sleeve 10, and then the dry particles will be filtered out. With the continuous accumulation of the dry particles and the combination of water molecules and particles in the space, water droplets will form on the conical sleeve 10, and thus the particles attached to the filter screen 11 will be brought down into the inside of the rectangular sleeve 3 by the water droplets. Then the air containing only welding flux will enter the activated carbon storage box 12. After being absorbed by the activated carbon, the welding flux in the air will be absorbed, and the filtered air will enter the inside of the vacuum pump main body 2 through the connecting pipe 22.

[0033] Embodiment 2

[0034] Refer to Figure 1-4, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the inside of the activated carbon storage box 12 is slidably connected to the dust blocking net 18, and the dust blocking net 18 can ensure that the activated carbon residue will not enter the interior of the vacuum pump body 2, and a blocking net with holes is also provided on the bottom surface of the inside of the activated carbon storage box 12, and a pair of symmetrical guide blocks are also provided on the vertical surface of the dust blocking net 18, and a rectangular baffle 19 is also provided on one of the vertical surfaces of the activated carbon storage box 12.

[0035] When in use, first follow the operating steps in Example 1. After working for a while, because a rectangular baffle 19 is provided on the vertical surface of the activated carbon storage box 12, a pair of mounting holes are opened on the vertical surface of the rectangular baffle 19, and the rectangular baffle 19 and the rectangular sleeve 3 are temporarily fixed by screws. At this time, you only need to use a tool to unscrew the screws, and then pull out the activated carbon storage box 12 through the handle provided on the vertical surface of the rectangular baffle 19, and then take out the dust blocking net 18. After replacing the new activated carbon, the previous steps of the installation can be reset.

[0036] The remaining structures are the same as those of Example 1.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
