Device of composite powder material

The utility model discloses a simple accurate control device of composite powder material. At present, an electromagnetic flow meter and other instruments are adopted and connected through a communication circuit and a total distributed control unit to implement the control, which can accurately control processing conditions, but greatly increases the investment cost, and has high operation and maintenance cost of equipment. The simple accurate control device is characterized in that the top portion of an autoclave is respectively connected with the bottoms of two high grooves through pipelines, one high groove is connected in series with a storing tank and a conveying pump through pipelines, and the other high groove is connected in series with another storing tank and another conveying pump through pipelines, the upper ends of two high grooves are respectively provided with return pipes which are connected with the storing tank. The simple accurate control device realizes the accurate control for processing conditions, has simple devices, and reduces the equipment investment and operation and maintenance cost.
