Vacuum mixing method and system

Abstract

The invention discloses a vacuum mixing method which comprises the following steps of: arranging a mixing bin, a power mechanism, a vacuumizing device, a feeding device and a control system; placing a charging bucket filled with materials on one side of the mixing bin; extending a feeding suction nozzle into the materials in the charging bucket; extracting gas in the mixing bin by the work of the vacuumizing device; sucking the materials into the mixing bin by the feeding suction nozzle through a flexible pipeline due to the fact that the atmospheric pressure is higher than the atmospheric pressure in the mixing bin; transmitting an instruction by the control system to close a first electronic valve at a feeding port in the mixing bin; continuously vacuuizing the mixing bin by the vacuumizing device; when the atmospheric pressure in the mixing bin reaches the vacuum standard, closing a second electronic valve at an exhaust opening in the mixing bin; and enabling the power mechanism to act at the rotating speed of 250-350t / m for 20 minutes to finish the mixing operation process. The invention also discloses a vacuum mixing system implementing the method.

Description

technical field [0001] The invention relates to mixing equipment, in particular to a vacuum mixing method for materials in the form of liquid or paste containing powder or lumps, and a vacuum mixing system for implementing the method. Background technique [0002] In many production industries, such as pigments, dyes, fine chemicals, pesticides, fertilizers, feed, food, medicine, electronics and other industries, it is often necessary to process one or more materials such as mixing, so that the proportion of materials in The components are mixed evenly to achieve a stable and high-quality use or processing effect. In the prior art, the commonly used mixing method is to place the material in an open container by manpower, and stir it with a stirring rod, which is inefficient. And the quality of stirring is not stable enough, often can not reach stable, good use or processing effect. Another way is to place the material in an open container and perform automatic stirring by m...

Problems solved by technology

[0002] In many production industries, such as pigments, dyes, fine chemicals, pesticides, fertilizers, feed, food, medicine, electronics and other industries, it is often necessary to process one or more materials such as mixing, so that the proportion of materials in The components are mixed evenly to achieve a stable and high-quality use or processing effect. In the prior art, the commonly used mixing method is to place the material in an open container by manpower, and stir it with a stirring rod, which is inefficient. Moreover, the quality of stirring is not stable enough, and it often does not achieve stable and good use or processing effects.

Another way is to place the material in an open container and perform automatic stirring by machinery. However, if the stirring is carried out by machinery, the material is also easily polluted by the air and dust in the stirring place during the stirring process, and it is also easy to pollute the surrounding area. Environmental pollution, and the mixing machine is large in size and complex in structure, maintenance, cleaning, etc. are more troublesome and costly
