[0033] Reference Figure 2 and Figure 3 , the outer sides of the fractionation column 2 2 and the fractionation column 3 3 are fixedly connected with positioning blocks 5, the outer peripheries of the fractionation column 1 1 and the fractionation column 2 2 are fixedly connected with mounting plates 6, the two positioning blocks 5 are respectively slidably connected to the middle parts of the two mounting plates 6, the tops of the mounting plates 6 are provided with positioning grooves 27, the two positioning blocks 5 are respectively plugged into the two positioning grooves 27, under the action of the positioning grooves 27, the two positioning blocks 5 can be quickly aligned with the two mounting plates 6, thereby accelerating the alignment speed between the fractionation column 1 1 and the fractionation column 2 2 as well as the fractionation column 2 2 and the fractionation column 3 3, and at the same time improving the installation speed between the fractionation column 1 1 and the fractionation column 2 2 as well as the fractionation column 2 2 and the fractionation column 3 3.

[0034] Reference Figure 2 and Figure 3 A compression spring 7 is fixedly connected to the inside of the mounting plate 6, and a card block 8 is fixedly connected to the other end of the compression spring 7. A card slot 9 is provided on the outer side of the fractionation column 2 2 and the fractionation column 3 3, and the two card blocks 8 are respectively plugged into the two card slots 9. When the positioning block 5 enters the mounting plate 6, the positioning block 5 will contact the card block 8 and squeeze the card block 8 to move the card block 8. When the card block 8 moves, the compression spring 7 will be compressed, so that the positioning block 5 can completely enter the middle part of the mounting plate 6. At this time, the card block 8 and the card slot 9 are in parallel positions, and the card block 8 is not squeezed by external force. Under the action of the compression spring 7, the card block 8 can be bounced into the card slot 9, so that the fractionation column 1 and the fractionation column 2 as well as the fractionation column 2 and the fractionation column 3 can be quickly connected and fixed.

The other side of the push plate 11 is rotatably connected with a connecting plate 12. The ends of the two connecting plates 12 away from the two push plates 11 are respectively fixedly connected to the outsides of the two card blocks 8. By pressing the pressure rod 10, the push plate 11 can be driven to slide in the mounting plate 6. At the same time, when the push plate 11 slides, the end of the connecting plate 12 away from the push plate 11 can pull the card block 8, so that the card block 8 can be pulled out of the middle of the card groove 9, and the fractionation column 1, fractionation column 2 and fractionation column 3 can be quickly separated. At the same time, the efficiency of assembly and disassembly between the fractionation column 1, fractionation column 2 and fractionation column 3 can be improved, and employees do not need to use tools and rotate the bolts for multiple turns, thereby reducing the labor intensity of employees.

[0037] Reference Figure 1 , Figure 4 and Figure 5The outer periphery of the intake pipe 13 is rotatably connected with a turntable 15, and a limiting groove 30 is provided on the outer side of the intake pipe 13. The turntable 15 is specifically slidably connected to the middle part of the limiting groove 30. Under the action of the limiting groove 30, the turntable 15 can be limited, which can avoid the turntable 15 from separating from the intake pipe 13 during rotation, so that the subsequent steps can be carried out normally. Two eccentric columns 16 are fixedly connected to the bottom of the turntable 15, and a baffle 17 is fixedly connected to the bottom of the eccentric column 16. A connecting rod belt 18 is arranged on the outer periphery of the eccentric column 16, and a clamping plate 19 is fixedly connected to the adjacent side of the two connecting rod belts 18. A limiting rod 21 is fixedly connected to the middle part of the support plate 14, and the two clamping plates 19 are both slidably connected to the outer periphery of the limiting rod 21, and a rubber pad 20 is fixedly connected to the adjacent side of the two clamping plates 19.

[0038] Reference Figure 1 , Figure 4 and Figure 5 When the turntable 15 rotates, the eccentric column 16 can be driven to move. At the same time, the clamping plate 19 can be limited under the action of the limiting rod 21 to prevent the clamping plate 19 from deviating when moving. Then, when the eccentric column 16 moves, the two connecting rods 18 can drive the two clamping plates 19 to clamp the air supply pipe connected to the outside of the intake pipe 13. At the same time, under the action of the rubber pad 20, the clamping plate 19 can be prevented from causing damage to the air supply pipe when clamping the air supply pipe, and the stability of the clamping can be improved.

[0039] Reference Figure 4 and Figure 5 The support plate 14 is internally fixedly connected to a limit assembly, the limit assembly includes a spring 23, the spring 23 is fixedly connected to the inside of the support plate 14, the other end of the spring 23 is fixedly connected to a stopper 24, and the outer periphery of the turntable 15 is fixedly connected to a plurality of latch teeth 22, the latch teeth 22 and the stopper 24 are in contact, when the turntable 15 rotates, the latch teeth 22 and the stopper 24 can be contacted and squeezed, so that the stopper 24 can compress the spring 23 and make the latch teeth 22 slide over the stopper 24, at this time, the spring 2 3 will pop out the stopper 24, and this operation is repeated until the air supply pipe is clamped. Under the action of the spring 23 and the stopper 24, the turntable 15 can be restricted to prevent the turntable 15 from rotating in the opposite direction, so that the two clamping plates 19 can stably clamp the air supply pipe. A pull rod is fixedly connected to the side of the stopper 24 close to the spring 23, and the pull rod passes through the support plate 14. By pulling the pull rod, the restriction on the turntable 15 can be released, and the turntable 15 can be rotated in the opposite direction and the clamping of the air supply pipe can be released.

[0040] Working principle: When in use, the support plate 14 can be fixed by using screws, and then the distillation column 1 can be fixed to prevent the distillation column 1 from tilting or collapsing. By inserting the positioning block 5 into the middle of the mounting plate 6, the positioning block 5 will contact the card block 8 when entering, and then the card block 8 can be squeezed and the card block 8 can compress the compression spring 7. When the slot 9 moves to the original position of the card block 8, the card block 8 can be bounced into the slot 9 under the action of the compression spring 7, and then the distillation column 1 and the distillation column 2 and the distillation column 2 and the distillation column 3 can be connected. By pressing the pressure rod 10, the push plate 11 can be driven to move. When the push plate 11 moves, the connecting plate 12 can pull the card block 8 out of the middle of the slot 9, and then the distillation column 1, the distillation column 2 and the distillation column 3 can be separated.

[0041] After the external air supply pipe and the air inlet pipe 13 are connected, the two eccentric columns 16 can be moved by rotating the turntable 15, and the two clamping plates 19 can only move in parallel under the action of the limit rod 21, and then when the eccentric column 16 moves, the two connecting rods 18 can drive the two clamping plates 19 to approach each other, so that the air supply pipe can be clamped, and at the same time, the turntable 15 can be limited under the action of the stopper 24 to prevent the turntable 15 from rotating in the opposite direction and causing the clamping failure. By pressing the stopper 24, the spring 23 can be squeezed and the limit on the turntable 15 can be released at the same time, and the turntable 15 can be rotated in the opposite direction to make the two clamping plates 19 move away from each other, so that the clamping of the air supply pipe can be released.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
