Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0029] Example 1:

[0030] See Figures 1-4This utility model provides a modular vacuum unit, comprising multiple frames connected in sequence and detachable from each other. Each frame is used to install the same or different types of vacuum pumps, forming a vacuum unit. Adjacent frames are guided by positioning pins 12. The positioning pins 12 ensure precise alignment of adjacent frames during installation, making installation more convenient.

[0031] Furthermore, each rack has a locating pin 12 installed at the top and a locating pin mounting hole at the bottom. When adjacent racks are installed, the locating pin mounting hole of the upper rack is aligned with the locating pin 12 of the lower rack and then inserted together.

[0032] See Figure 5 To prevent the frame from twisting and to ensure the overall rigidity of adjacent frames assembled together, a positioning block 13 is fixedly installed on one side of the positioning pin 12. The bottom of the positioning block 13 has a concave spherical groove. Below the positioning block 13 is a spring mounting groove 16, within which a detachable spring 15 is installed. A steel ball 14 is positioned on top of the spring 15, located within the spherical groove. In practical applications, the spring mounting groove 16 is formed on the frame on which the positioning pin 12 is installed, located on one side of the positioning pin 12.

[0033] A high-strength screw 17 is provided on the other side of the positioning pin 12 for fixing the frame.

[0034] After the positioning pin 12 is positioned, steel balls 14 are installed to prevent the adjacent frames from twisting. The steel balls 14 are matched with the spherical grooves on the positioning block 13. After the upper and lower adjacent frames are assembled in place, the steel balls 14 are clamped between the upper and lower frames to prevent the adjacent frames from twisting and causing insufficient rigidity. The frames are then fixed with high-strength screws 17.

[0035] See Figure 3 and Figure 6 Each frame is equipped with a support beam 11, which is used to fix the vacuum pump.

[0036] The support beam 11 is mounted on the frame via an adjustable positioning assembly. Specifically, the adjustable positioning assembly includes a U-shaped positioning groove 18 located below the support beam 11, and the support beam 11 is fixed in the U-shaped positioning groove 18 by double U-shaped lead screws 19. The support beam 11 can be adjusted according to the positional requirements of the vacuum pump, causing the relative position of the support beam 11 and the U-shaped positioning groove 18 to change.

[0037] The adjustable positioning components allow for the installation of different models of vacuum pumps on the frame, providing a wide range of compatibility. Adjusting the position of the support beam 11 ensures compatibility with various vacuum pump models. Furthermore, to prevent the support beam 11 from loosening or tilting and to ensure its stability, adjusting screws are installed on both the left and right sides of the support beam 11.

[0038] Specifically, a left fixing block 23 is provided on the left side of the support beam 11, and a left adjusting screw 24 is screwed onto the left fixing block 23. One end of the left adjusting screw 24 abuts against the support beam 11 and the other end is fixed to the left fixing block 23 by a fixing nut 22. When adjustment is required, loosen the fixing nut 22, rotate the left adjusting screw 24 to move forward or backward, and tighten the fixing nut 22 after the position is determined.

[0039] A right fixing block 20 is provided on the right side of the support beam 11. A right adjusting screw 21 is screwed onto the right fixing block 20. One end of the right adjusting screw 21 abuts against the support beam 11, and the other end is fixed to the right fixing block 20 by another fixing nut 22. When adjustment is required, loosen the fixing nut 22, rotate the right adjusting screw 21 to move forward or backward, and tighten the fixing nut 22 after the position is determined.

[0040] See Figure 1 and Figure 2 This utility model preferably comprises three frames, namely a first frame 1, a second frame 2, and a third frame 3 arranged from top to bottom. A two-stage Roots vacuum pump 5 is installed inside the first frame 1, forming the second pump module of the vacuum unit; a first-stage Roots vacuum pump 6 is installed above the first frame 1, forming the first pump module of the vacuum unit. A screw vacuum pump 4 is installed inside the second frame 2, forming the forestage pump module of the vacuum unit.

[0041] A flushing tank 7 and a purge gas assembly 10 are installed on one side (preferably the left side) of the second frame 2; an exhaust pipe 8 is installed on one side of the screw vacuum pump 4, the exhaust pipe 8 is connected to a recovery assembly 9, and the recovery assembly 9 is installed on the third frame 3.

[0042] The frames can be combined in any way according to customer needs. When the vacuum unit only requires the screw vacuum pump 4 or the two-stage Roots vacuum pump 5, only the second frame 2 is needed; when the vacuum unit requires the two-stage Roots vacuum pump 5, the first frame 1 and the second frame 2 are used; when the vacuum unit needs to recover the component 9, the third frame 3 is used. The frame is selected according to the customer requirements to complete the modular design of the vacuum unit.

[0043] The position of the support beam 11 in the frame is adjustable. Taking the support beam 11 on the second frame 2 as an example, the support beam 11 at the lower part of the second frame 2 is provided with a U-shaped positioning groove 18. The support beam 11 is fixed in the U-shaped positioning groove 18 by a double U-shaped screw 19 to prevent the double U-shaped screw 19 from rotating. Depending on the model of the screw vacuum pump, multiple double U-shaped grooves are provided on the U-shaped positioning groove 18, which can quickly and accurately position the support beam 11. The double U-shaped screw 19 is locked and fixed by a U-shaped rod nut 25 to achieve the fixation of the support beam 11.

[0044] To prevent the support beam 11 from loosening or tilting, a right fixing block 20 and a left positioning block 23 are provided on both sides of the support beam 11. A right adjusting screw 21 is provided on the right fixing block 20, and a left adjusting screw 24 is provided on the left fixing block 23. The position of the support beam 11 can be finely adjusted by the right adjusting screw 21 and the left adjusting screw 24 on both sides, while providing clamping force on both sides to prevent the support beam 11 from shifting or tilting.

[0045] The adjustable positioning components enable a unified structure for the second frame 2, and by simply adjusting the position of the internal support beam 11, it can be compatible with various models of screw vacuum pumps.

[0046] This utility model provides a modular vacuum unit. Through modular frame design, the development cycle is significantly shortened and production efficiency is improved. The complex vacuum unit is modularized, with each frame compatible with multiple vacuum pump models, enabling rapid design of vacuum units with different pumping speeds. Frames can be flexibly added or removed according to customer requirements to meet different configuration needs. Mass production of frames ensures rational and orderly production, reducing overall costs. Proper placement saves space and reduces warehousing workload. Rapid and flexible assembly shortens the production cycle and improves on-time delivery rates. It facilitates production assembly and on-site handling by customers, and is convenient for the modular transportation and assembly of large units. No heavy lifting equipment is required; modular disassembly and assembly facilitate maintenance, upkeep, and future replacement.

[0047] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
