[0002] In industrial production, compressed air is widely used in pneumatic tools, pneumatic control systems, chemical production and other fields. Compressed air buffer tank, as an important part of compressed air system, is mainly used for stabilizing air pressure and reducing air flow pulsation. However, most of the existing buffer tanks are simple one-piece stainless steel tank structures. Once damaged or need to be maintained, it is difficult to disassemble and assemble. The structure is simple, although it has certain buffering function, but the buffering effect is limited, and the stability is poor. In addition, it also lacks the processing capacity of impurities and moisture in compressed air, which may cause the blockage or damage of downstream equipment. SUMMARY

[0003] Therefore, to solve the above technical problems, the utility model provides a compressed air buffer tank with reasonable structure design, which can be disassembled and assembled, easy to maintain, has good buffering effect, strong stability and impurity and moisture removal function.

[0004] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0008] Impurity and moisture removal device, the impurity and moisture removal device is detachably installed in the right kettle cover and located at the left side of the air outlet.

[0009] The tank body is a detachable structure, and the left kettle cover, the middle kettle body and the right kettle cover are detachable, facilitating later maintenance; the left kettle cover is the installation position of the air inlet and the safety port, used for introducing compressed air and releasing pressure through the safety port when the pressure is too high, ensuring the safety of the equipment; the middle kettle body is the installation position of the buffer device, providing sufficient space for the buffering and stabilization of the airflow; the right kettle cover is the installation position of the impurity and moisture removal device and the air outlet, used for removing moisture and impurities from the air after buffering treatment and then outputting the compressed air; after the compressed air enters the tank body, it directly impacts the buffer disc, and the buffer disc is elastically connected with the buffer seat one to absorb the impact force of the airflow, reduce the airflow pulsation, and the airflow after the first-stage buffering flows rightwards between the buffer disc and the inner wall of the middle kettle body, impacting the buffer plate which is elastically supported by the buffer seat two, further weakening the airflow pulsation, and after two-stage buffering, the airflow pulsation can be effectively reduced, and the stability of the output airflow is improved; the airflow after the buffering is output from the air outlet after moisture and impurities removal by the moisture and impurity removal device, ensuring that the downstream equipment can use pure, dry and stable output air.

[0010] Further, the inner wall of the tank body is provided with a corrosion-resistant coating; the left kettle cover, the middle kettle body and the right kettle cover are detachably connected by bolts, and sealing pads are arranged at the connection positions.

[0018] The gas which is buffered by the buffer disc impacts on the buffer plate, and then flows to the right after flowing out of the annular hole in the middle of the right buffer plate under the guidance of the annular conical structure in the inner side of the buffer plate.

[0019] Further, a mounting seat for connecting with the buffer seat two is arranged on the left end surface of the buffer plate near the outer edge; the mounting seat has a plurality of mounting seats which are distributed at equal intervals in the circumferential direction of the buffer plate; the buffer seat two has a plurality of buffer seat two which are arranged one by one corresponding to the plurality of mounting seats.
