[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder as raw material, and then forms and sinters it to produce metal materials, composite materials and various types of products. Due to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a vital role in the development of new materials.

[0003] In the powder metallurgy production process, due to the different components of different types of products, in order to avoid quality problems such as dirtiness and coarseness, cleaning agents must be used for cleaning after a round of production.

The cleaning agent barrel is heavy, the temperature in the boiler room is high, and the tank top is filled with hot air. The operation is labor-intensive and there are safety risks of high-altitude and high-temperature operations. At the same time, the tank body storing the cleaning agent has poor sealing properties, and it is difficult to ensure sealing properties for long-term storage. To this end, we designed a cleaning agent delivery device for powder metallurgy to solve the above technical problems. Utility Model Content

[0018] 2. When the device is delivering liquid, the external compressor drives the air flow through the quick connector and the compressed air pipe to enter the upper part of the storage tank, so that the pressure above the storage tank becomes larger, thereby squeezing the cleaning agent, and the cleaning agent is delivered to the specified height position through the infusion tube, avoiding high-altitude and high-temperature operations for workers, reducing work intensity, and improving the operating safety of the device.
