Environment-friendly powder automatic-metering and feeding device and environment-friendly powder automatic-metering and feeding method

Abstract

The invention discloses an environment-friendly powder autometering and feeding device and an environment-friendly powder automatic-metering and feeding method and belongs to the field of ink, coating and paint production. According to the device, a powder tank (10) is supported inside a rectangular supporting platform on the top surface platform of the rectangular supporting platform by virtue of support lugs; a transition cavity is connected with the powder tank by virtue of a large valve and connected with a small valve; a weighing barrel is connected with an outlet of the small valve in a flexible connection, and the supporting lugs at the bottom of the weighing barrel are supported on an electronic scale; a discharge valve is arranged on the lower end of the weighing barrel and connected with a powder feeding opening of a dispersion tank on an ink production line. Materials in the powder barrel is sucked into the vacuum feed hopper by a vacuum pump through a vacuum filter; after the vacuum feed hopper is full, powder in the hopper can be automatically put in the weighing barrel in the powder tank by virtue of the discharge valve and is weighed by virtue of the electronic scale. During the whole metering and feeding process, no dust flies into air, so that the device and the method are remarkable in environment-friendly significance; manual weighing and carrying can be omitted, and the labor intensity can be reduced.

Description

technical field [0001] The invention belongs to the field of ink, paint and paint production, and in particular relates to an environment-friendly automatic metering powder feeding device and method. Background technique [0002] In the mixed production process of inks, paints, paints and different types of solid powders, the feeding of solid powders (such as dyes, pigments, titanium dioxide, carbon black, talcum powder, etc.) must be involved. At present, there are two powder feeding methods : The first is manual weighing and feeding, that is, after manual weighing, it is directly poured into the dispersion tank for stirring and dispersing. This method will generate dust in the two links of weighing and pouring, causing air pollution and endangering the safety of the operator. Healthy and labor-intensive, most small production enterprises adopt this method; the second is to manually weigh the material and pour it into the hopper, and the powder in the hopper is sucked into ...

[0002] In the mixed production process of inks, paints, paints and different types of solid powders, the feeding of solid powders (such as dyes, pigments, titanium dioxide, carbon black, talcum powder, etc.) must be involved. At present, there are two powder feeding methods : The first is manual weighing and feeding, that is, after manual weighing, it is directly poured into the dispersion tank for stirring and dispersing. This method will generate dust in the two links of weighing and pouring, causing air pollution and endangering the safety of the operator. Healthy and labor-intensive, most small production enterprises adopt this method; the second is to manually weigh the material and pour it into the hopper, and the powder in the hopper is sucked into the dispersion tank through the pipeline, that is, the water circulation pump is connected to the outlet of the dispersion tank Such equipment with strong suction will suck the powder into the dispersing tank. A certain scale of production plants will separate the hopper from the outside world with a small house, which can reduce the powder flying during the pouring process, but the weighing has not yet been solved. It is difficult to avoid the air pollution caused by flying powder in the weighing process, and it is also difficult to avoid the water pollution problem caused by the water circulation pump (part of the dust is absorbed into the water, which avoids the spread into the air)
