Detailed implementation mode

[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, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-5 , a pneumatic conveying silo pump with a long conveying distance, including a pneumatic conveying silo pump body 1 and a connecting pipe 3. One end of the pneumatic conveying silo pump body 1 is installed with a conveying pipe 2. One end of the conveying pipe 2 is connected and fixed with a sleeve 4. An I-shaped ring 15 is welded on the outer side of the conveying pipe 2. A rotating ring 9 is slidably connected to the outer side of the I-shaped ring 15. The I-shaped ring 15 can position the rotating ring 9 so that it can rotate stably. A torsion spring 8 is sleeved on the outer side of the conveying pipe 2, and both ends of the torsion spring 8 are fixed to the conveying pipe 2 and the rotating ring 9 respectively. The torsion spring 8 facilitates the automatic reset of the rotating ring 9. A plurality of fixing blocks 10 are fixed to one side of the rotating ring 9 by bolts. An arc-shaped insertion rod 14 is welded to one side of the fixing block 10. A fixing ring 5 is welded on the outer side of the connecting pipe 3. A plurality of sliding rods 7 are fixed to one side of the fixing ring 5 by bolts, and arc-shaped insertion holes 11 are opened at one ends of the plurality of sliding rods 7, and the arc-shaped insertion holes 11 are inserted with the arc-shaped insertion rods 14. The staff rotates the rotating ring 9 to make it rotate along the I-shaped ring 15, and the torsion spring 8 deforms until the arc-shaped insertion rod 14 moves out of the arc-shaped insertion hole 11, and then pulls the fixing ring 5 along the length direction of the connecting pipe 3 to separate the connecting pipe 3 from the conveying pipe 2, thereby disassembling the connecting pipe 3.

[0025] In the present utility model, it should be noted that a clamping groove 16 is opened at one end of the connecting pipe 3, and the conveying pipe 2 is clamped with the clamping groove 16. A sealing gasket 17 is adhesively bonded to the inner wall of the clamping groove 16, and the sealing gasket 17 is in contact with the conveying pipe 2. Through the cooperation of the sealing gasket 17 and the clamping groove 16, the connection between the connecting pipe 3 and the conveying pipe 2 is made tighter. A plurality of avoidance grooves 6 are opened on the outer side of the sleeve 4, and the sliding rods 7 are located in the avoidance grooves 6. The avoidance grooves 6 can avoid the sliding rods 7. A plurality of limiting grooves 13 are opened on the circumferential inner wall of the sleeve 4. A plurality of limiting blocks 12 are fixed to the outer side of the connecting pipe 3 by bolts. The limiting grooves 13 are slidably connected with the limiting blocks 12. Through the cooperation of the limiting blocks 12 and the limiting grooves 13, the connecting pipe 3 is guided during installation, which is convenient for the staff to position and install.

[0026] Working principle: When it is necessary to disassemble the connecting pipe 3, first, the staff rotates the rotating ring 9 so that it rotates along the I-shaped ring 15, and the torsion spring 8 deforms until the arc-shaped insertion rod 14 moves out of the arc-shaped insertion hole 11. Then, the fixed ring 5 is pulled along the length direction of the connecting pipe 3, so that the sliding rod 7 gradually moves out of the avoidance groove 6. At the same time, the limiting block 12 moves along the limiting groove 13 until the sliding rod 7 completely moves out of the avoidance groove 6, thereby disassembling the connecting pipe 3.

[0027] In addition, the terms "installation", "setting", "connection", and "socket connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, components, or parts. Those of ordinary skill in the art can understand the specific meanings of the above terms in this application according to specific circumstances.
