Material mixing process based on vacuum mixing drum

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.

Description

technical field [0001] The invention relates to a material mixing process based on a vacuum mixing tank. Background technique [0002] Mixers are often used in modern food or chemical industries, and these industries have high requirements for the purity of materials when mixing, and it is required to minimize the mixing of impurities during mixing, so mixing in ordinary environments can no longer meet the requirements of these industries. , there are also some vacuum mixers on the market now, which allow the materials to be in a vacuum environment during mixing to prevent dust in the air from entering the mixing materials, but the traditional vacuum mixers have problems of uneven mixing and insufficient dust removal, especially after mixing. When the upper cover is opened and the material is poured, the material will still be in contact with the dust in the air. Compared with stirring the material directly in the air, although the contact time with the air is shortened, the...
