Abstract
The invention discloses a material mixing process based on a vacuum mixing drum. The vacuum mixing drum comprises a mixing drum and an upper cover, wherein an extraction pipe and an air inlet pipe are arranged on the side wall of the mixing drum, a pneumatic cylinder used for lifting is arranged above the upper cover, and a discharge port and a pneumatic valve are formed in and arranged at the bottom of the mixing drum. Firstly, the upper cover is lifted to discharge by virtue of the pneumatic cylinder, then the upper cover is closed to exhaust, the mixing drum is vacuumized, and subsequently, air enters again after mixing for a certain time, so that air pressure in the mixing drum conforms to ambient pressure; when the air enters, the pneumatic valve is opened, materials flow out from the discharge port, and the pneumatic cylinder is driven by a part of air to lift the upper cover, so as to be convenient to discharge again. The whole process is automatically completed by air pressure, the problems of bad dust removing effect and non-uniform mixing of a traditional mixing drum are solved, the upper cover of the vacuum mixing drum can be quickly lifted with labor saving, and the working efficiency is improved.
