Problems solved by technology

Pneumatic conveying uses a vacuum pump as the power source to vacuum out the powder for conveying. This method is currently the most commonly used powder conveying method with high conveying efficiency, but the disadvantage is also obvious, that is, it cannot carry out quantitative control of powder conveying.
The structure of pipe chain transportation is relatively complicated. At the same time, pipe chain transportation can only carry out relatively rough quantitative transportation, which is suitable for relatively large-scale production. However, for some smaller scales such as the pharmaceutical industry, high quantitative accuracy is required. Such It is difficult for the device to meet the requirements

Abstract

The invention discloses a powder conveying metering device. The lower end of a bin body is fixedly disposed at the upper end of a feed box body, and the lower end of one side of the feed box body is provided with a discharge tube. A powder conveying spiral is disposed in the discharge tube and the feed box body, and one end of the powder conveying spiral is rotatingly disposed on a side wall of the feed box body. One end part of the powder conveying spiral is connected with a speed reduction motor through a shaft coupler, and is driven by the speed reduction motor to operate. A stirring shaftis disposed in the feed box body, and one end of the stirring shaft is rotatingly disposed on the feed box body. An end part of the stirring shaft is connected with the powder conveying spiral througha belt, and a tensioning device is disposed at an inner side of the belt. The feed box body is fixedly disposed at the upper side of a bottom tray, and the bottom tray is disposed at the upper side of a weighing platform. The device is simple and reasonable in structure, and can achieve the precise metering.

Description

technical field [0001] The invention relates to a conveying and metering device, in particular to a powder conveying and metering device. Background technique [0002] Now powder transportation is widely used in the transportation of light dry powder such as metal powder, coal powder and chemical industry. The common methods of transportation include pneumatic transportation and pipe chain transportation. Pneumatic conveying uses a vacuum pump as the power source to vacuum out the powder for conveying. This method is currently the most commonly used powder conveying method with high conveying efficiency, but the disadvantage is also obvious, that is, it cannot carry out quantitative control of powder conveying. . The structure of pipe chain transportation is relatively complicated. At the same time, pipe chain transportation can only carry out relatively rough quantitative transportation, which is suitable for relatively large-scale production. However, for some smaller sca...
