Detailed Embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those of ordinary skill in the art without making creative efforts all fall within the protection scope of the present utility model.

[0024] Referring to Figures 1-5 , an internal bypass pipe pneumatic conveying device includes a straight pipe 1 and a plurality of U-shaped pipes 4 with different lengths. Both ends of the U-shaped pipe 4 are installed with second fixing plates 6. Two avoidance openings 9 are opened inside the second fixing plate 6. A plurality of connecting pipes 3 are fixedly connected to the top of the straight pipe 1. The top ends of the connecting pipes 3 are installed with first fixing plates 7. Two clamping blocks 13 are fixed on the upper surface of the first fixing plate 7 by bolts, and the clamping blocks 13 pass through the avoidance openings 9. Avoidance grooves 12 are opened on one side of the two clamping blocks 13. Thread grooves 5 are opened at both ends of the U-shaped pipe 4. A rotating ring 8 is threadedly connected to the outside of the thread groove 5. Arc-shaped plates 11 are welded to the outer walls on both sides of the rotating ring 8. A wedge-shaped plate 16 is fixed on the upper surface of the arc-shaped plate 11 by bolts. Rotate the rotating ring 8 to make the arc-shaped plate 11 drive the wedge-shaped plate 16 into the avoidance groove 12 until the arc-shaped plate 11 and the wedge-shaped plate 16 are in close contact with the avoidance groove 12, realizing the connection and fixation between the first fixing plate 7 and the second fixing plate 6, and the arc-shaped plate 11 and the wedge-shaped plate 16 are located inside the avoidance groove 12. Reverse-rotate the rotating ring 8 to gradually move the wedge-shaped plate 16 out of the avoidance groove 12, and then pull the U-shaped pipe 4 upward to separate the second fixing plate 6 from the first fixing plate 7, and at the same time, the clamping block 13 moves out of the avoidance opening 9, thereby realizing the quick and convenient disassembly of the U-shaped pipe 4.

[0025] In the present utility model, it should be noted that two guiding holes 10 are opened inside the second fixing plate 6. Two guiding rods 17 are fixed on the upper surface of the first fixing plate 7 by bolts, and the guiding rods 17 are inserted into the guiding holes 10. By the cooperation of the guiding rods 17 and the guiding holes 10, it is convenient for the staff to position and install the first fixing plate 7 and the second fixing plate 6. An annular groove 14 is opened on the upper surface of the first fixing plate 7, and a sealing ring 15 is bonded in the annular groove 14. The sealing ring 15 makes the connection between the first fixing plate 7 and the second fixing plate 6 tighter. The sealing ring 15 is in contact with the second fixing plate 6. A plurality of anti-slip lines are opened on the outside of the rotating ring 8, increasing the friction between people's hands and the rotating ring 8, and being more anti-slip. The height of the guiding rod 17 is higher than that of the clamping block 13.

[0026] Working principle: When it is necessary to disassemble the U-shaped tube 4, first rotate the swivel ring 8 to gradually move the wedge-shaped plate 16 out of the avoidance groove 12, and then pull the U-shaped tube 4 upward to separate the second fixed plate 6 from the first fixed plate 7. At the same time, the guide rod 17 moves out of the guide hole 10, and the clamping block 13 moves out of the avoidance port 9, thereby realizing the quick and convenient disassembly of the U-shaped tube 4.
