[0002] With the rapid development of my country's machinery industry, higher requirements are put forward for casting production and the quality of castings, that is, to produce high-quality, high-precision castings with low consumption and high efficiency, and the regeneration and recovery of water glass sand is very important. The vibration regeneration machine integrates multiple functions such as sand dropping, crushing, film stripping and screening. It has a compact structure and occupies a small area. The machine is powered by a vibration motor and mainly works by rubbing. The sand crushing rate is low, the recovery rate is high, and the regenerated sand grain type is more complete.

[0003] During the pneumatic impact regeneration of gravel, the gravel is ejected from the blow pipe, passes through the impact regenerator and enters the sand box for storage. Since the blow pipe is in contact with the gravel for a long time, it will be damaged after long-term use. At the same time, the existing blow pipe is often connected with parts such as bolts and flanges. Although this method can achieve the sealing of the pipeline, the steps are relatively cumbersome during installation and disassembly, resulting in a slow replacement efficiency of the blow pipe. Therefore, a high wear-resistant blow pipe of a pneumatic impact regenerator is proposed to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 2 The utility model provides an embodiment: a high wear-resistant blowing pipe of a pneumatic impact regeneration machine, including a main pipeline 1 and a nozzle 3. The main pipeline 1 and the nozzle 3 are both pipelines of the pneumatic impact regeneration machine. The main pipeline 1 is used to transport materials such as gravel, and the nozzle 3 is used to blow the transported materials to the impact regeneration device. A flange 2 is fixedly connected to one end of the main pipeline 1, and a flange 2 7 is fixedly connected to one end of the nozzle 3. After aligning the flange 2 and the flange 2 7, the installation can be carried out. A slide 4, a through hole 5 and a positioning hole 6 are opened in the middle of the flange 2. The slide 4 is located between the through hole 5 and the positioning hole 6, and the slide 4, the through hole 5 and the positioning hole 6 are connected. A spring rod 8 is fixedly connected to the outside of the flange 2 7. The spring rod 8 is in contact with the flange 1 2. The distance between the flange 1 2 and the flange 2 7 is adjusted by the spring rod 8, thereby providing a guarantee for the connection between the flange 1 2 and the flange 2 7. A clamping rod 9 is fixedly connected to the outside of the flange 2 7, and the clamping rod 9 is clamped with the positioning hole 6. When in use, align the clamping rod 9 with the through hole 5 in the middle of the flange 2 and pass through it, then rotate the nozzle 3 to drive the clamping rod 9 to rotate and slide along the slideway 4, and when the clamping rod 9 reaches the position of the positioning hole 6, the preliminary connection between the main pipeline 1 and the nozzle 3 can be completed. After the nozzle 3 is released, the clamping rod 9 and the positioning hole 6 can be clamped under the action of the spring rod 8, so that the preliminary connection between the main pipeline 1 and the nozzle 3 can be completed. The operation is simple and the time required for replacing the nozzle 3 can be greatly reduced.

[0031] Reference Figure 1-Figure 3 , a connecting component is also connected to the end of flange 2 7. The connecting component includes a connecting pipe 10. When the main pipeline 1 and the nozzle 3 are connected, the connecting pipe 10 will be inserted into the main pipeline 1, so as to ensure the connection strength between the main pipeline 1 and the nozzle 3. The connecting pipe 10 is in a truncated cone shape, which can facilitate the docking of flange 1 2 and flange 2 7 while ensuring the sealing after the connection. And the inner side of flange 1 2 is provided with an inclined surface adapted to the connecting pipe 10, so as to facilitate the insertion of the connecting pipe 10 into the middle of flange 1 2 and the main pipeline 1. The inner and outer edges of the connecting pipe 10 facing one end of the main pipeline 1 are provided with bevels, so as to facilitate the alignment of the connecting pipe 10 with the main pipeline 1.

[0032] Reference Figure 2-Figure 3 , multiple sets of sealing rings 11 are fixedly connected to the outer periphery of the connecting pipe 10, and the sealing rings 11 are in contact with the flange 12. The sealing rings 11 ensure the sealing between the connecting pipe 10 and the flange 2, thereby ensuring the normal use of the nozzle 3. A sealing gasket 12 is fixedly connected to the side of the flange 27 facing the flange 2, and the sealing gasket 12 is in contact with the flange 2. The sealing gasket 12 can further ensure the sealing between the flange 2 and the flange 27, and a hole for the spring rod 8 and the clamping rod 9 to pass through is opened in the middle of the sealing gasket 12.

[0033] Reference Figure 4 The side of the connecting pipe 10 close to the flange 2 is fixedly connected with a ceramic wear-resistant layer 13. The ceramic wear-resistant layer 13 improves the wear resistance of the connecting pipe 10 and reduces wear when hit by gravel. This part accounts for a large proportion, which can ensure that the connecting pipe 10 can be used for a long time, thereby reducing the replacement frequency. A fluorine lining layer 14 is fixedly connected to the inside of the nozzle 3. A reinforcement layer 15 is fixedly connected to the inside of the fluorine lining layer 14. The reinforcement layer 15 can increase the overall structural strength of the nozzle 3 to prevent damage to the nozzle 3 caused by impact. A ceramic wear-resistant layer 2 16 is fixedly connected to the inside of the reinforcement layer 15. The ceramic wear-resistant layer 2 16 can also provide wear resistance for the inner wall of the nozzle 3 to ensure the long-term use of the nozzle 3.

[0034] Working principle: When in use, align the clamping rod 9 with the through hole 5 in the middle of flange 1 2, and then push flange 2 7 toward flange 1 2 so that the clamping rod 9 passes through the through hole 5 and squeezes the spring rod 8. At this time, the connecting pipe 10 will be inserted into the middle of flange 1 2, and then the nozzle 3 is rotated to drive the clamping rod 9 to rotate and slide along the slide 4. When the clamping rod 9 reaches the position of the positioning hole 6, the nozzle 3 is released. Under the action of the spring rod 8, the clamping rod 9 and the positioning hole 6 can be engaged, thereby completing the connection between the main pipeline 1 and the nozzle 3. At the same time, the connection between the main pipeline 1 and flange 2 will be sealed under the action of the sealing gasket 12 and the sealing ring 11 to ensure the normal progress of the pneumatic impact.

[0035] Secondly, a ceramic wear-resistant layer 13 is provided on the outer edge of the connecting pipe 10 to reduce wear when hit by gravel, and this part accounts for a large proportion, which can ensure that the connecting pipe 10 can be used for a long time. At the same time, the ceramic wear-resistant layer 16 can also provide wear resistance for the inner wall of the nozzle 3 to extend the service life of the nozzle 3. Then, the overall structural strength of the nozzle 3 can be increased by the reinforcement layer 15 to prevent the nozzle 3 from being damaged by impact.

[0036] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
