[0005] To achieve the above objectives, this utility model provides the following technical solution: a blower interchangeable device, comprising a mounting base on which a first Roots blower, a second Roots blower, and a third Roots blower are respectively mounted. The output ends of the first, second, and third Roots blowers are respectively connected to a first conveying pipe, a second conveying pipe, and a third conveying pipe. The ends of the first and third conveying pipes are also connected to identical first and second blower filters. The bottoms of the first and second blower filters are fixed to the surface of the mounting base. A fourth conveying pipe is connected between the first, second, and third conveying pipes. Interchangeable valve assemblies are provided at the center of the first, second, and third conveying pipes and on both sides of the second conveying pipe on the fourth conveying pipe. The interchangeable valve assembly includes a valve assembly housing, a rear pipe at the bottom of the valve assembly housing, a front pipe on the right side of the valve assembly housing, and a push cylinder on the left side of the valve assembly housing. The piston rod head of the push cylinder is provided with a silicone pad adapted to the front pipe. A solenoid valve connected for control is provided above the push cylinder.

[0006] Preferably, the first fan filter includes a filter barrel, a filter dust collection bin connected to the bottom of the filter barrel, a filter top cover located at the top of the filter barrel, a filter air chamber located below the filter top cover, a filter pulse valve connecting the filter air chamber and the filter barrel, an oil-water separator located at the bottom of the filter air chamber, and a filter support frame also provided on the surface of the filter barrel.

[0007] Preferably, the number of interchangeable valve groups is 5, and the 5 interchangeable valve groups can be controlled to start and stop simultaneously.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: a blower interchangeable device, including a mounting base 1. A first Roots blower 2, a second Roots blower 3, and a third Roots blower 4 are respectively mounted on the mounting base 1. The output ends of the first Roots blower 2, the second Roots blower 3, and the third Roots blower 4 are respectively connected to a first conveying pipe 5, a second conveying pipe 6, and a third conveying pipe 7. The ends of the first conveying pipe 5 and the third conveying pipe 7 are also connected to identical first blower filters 9 and second blower filters 10. The bottoms of the first blower filters 9 and the second blower filters 10 are fixed to the surface of the mounting base 1. A fourth conveying pipe 8 connects the first conveying pipe 5, the second conveying pipe 6, and the third conveying pipe 7. Interchangeable valve assemblies 11 are provided at the center of the first conveying pipe 5, the second conveying pipe 6, and the third conveying pipe 7, and on the fourth conveying pipe 8 on both sides of the second conveying pipe 6. The interchangeable valve assembly 11 includes a valve assembly housing 111, a rear pipe 113 located at the bottom of the valve assembly housing 111, a front pipe 112 located on the right side of the valve assembly housing 111, and a push cylinder 114 located on the left side of the valve assembly housing 111. The piston rod head of the push cylinder 114 is provided with a silicone pad 115 adapted to the front pipe 112. The front pipe 112 and the rear pipe 113 are made of 86 stainless steel. A solenoid valve 12 is provided above the push cylinder 114 for control connection. There are 5 interchangeable valve assemblies 11, and all 5 interchangeable valve assemblies 11 can be controlled to start and stop simultaneously. An acrylic window 13 is also embedded on the surface of the valve assembly housing 111, and a rubber pad 14 is provided at the connection between the edge of the acrylic window 13 and the valve assembly housing 111.

[0019] The first fan filter 9 includes a filter body 91, a filter dust collection bin 92 connected to the bottom of the filter body 91, a filter top cover 93 located at the top of the filter body 91, a filter air chamber 94 located below the filter top cover 93, a filter pulse valve 95 connecting the filter air chamber 94 and the filter body 91, and an oil-water separator 96 located at the bottom of the filter air chamber 94. The surface of the filter body 91 is also provided with a filter support frame 97. The structure of the second fan filter 10 is exactly the same as that of the first fan filter 9.

[0020] The specific usage and function of this embodiment: During normal operation, the three Roots blowers can work simultaneously. By relying on the connected first conveying pipe 5, second conveying pipe 6, and third conveying pipe 7, and passing through the first blower filter 9 and the second blower filter 10, impurities (such as dust, moisture, oil, etc.) in the gas are filtered, protecting the equipment from pollution damage, improving gas purity, and extending the service life of the Roots blowers, so as to better drive the feeding and conveying of plastic film. When one of the Roots blowers malfunctions and cannot operate normally, the other two Roots blowers can continue to operate normally. The gas delivery route can be adjusted by using the interchangeable valve group 11. For example, if the first Roots blower 2 malfunctions, the interchangeable valve group 11 located on the first delivery pipe 5 pushes the piston rod forward through the internal push cylinder 114, causing the silicone pad 115 at the head to block the front pipe 112, preventing gas from entering the malfunctioning first Roots blower 2. The gas can then be smoothly delivered to the second Roots blower 3 and the third Roots blower 4 through the second delivery pipe 6, the third delivery pipe 7, and the fourth delivery pipe 8. If other Roots blowers malfunction, the interchangeable valve group 11 on each delivery pipe can be controlled at will according to the site conditions to flexibly control the gas delivery route, ensuring the normal and stable operation of the entire production line system and further improving the material feeding and delivery efficiency of plastic film.
