Problems solved by technology

[0005] However, because the powder feeding is manually opened, poured, and shaken into the tank, although the dust can be effectively reduced under the action of the exhaust fan, every time feeding, it is especially like the white carbon of the gas phase method. Black superfine powder material, its suspension speed is small, and a large amount of dust is easy to be generated when feeding, which will inevitably cause spillage
At the same time, since the filter is not equipped with a back-blowing device, the filter is easy to clog when it comes to materials with a large amount of dust and strong adsorption, and needs to be removed and cleaned frequently, thus affecting the continuity of production
In addition, this open feeding method that is in full contact with the air, especially in the case of a relatively humid environment, is prone to moisture for materials with strong hydrophilicity, and the existing device cannot realize the drying function of powder materials, which requires Additional equipment such as dryers or drying towers are purchased for drying, thereby increasing cost input and occupying space

Abstract

The invention discloses a continuous powder conveying device with a drying function. The device adopts a full-automatic and full-closed design, integrates the negative pressure pneumatic conveying of a high-pressure centrifugal fan and the conveying of a pneumatic diaphragm pump, and can overcome the defects of the prior art through a fan with lower power. The continuous powder conveying device with the drying function comprises an unpacking mechanism 1, a feeding pneumatic diaphragm pump 2, a heat exchanger 3, a regulating valve 4, a temperature and humidity sensor 5, a feeding gas-lock valve 6, a powder feeding pipeline 7, a discharge gas-lock valve 8, a cyclone separator 9, a collection mechanism 10, a filtering mechanism 11, an air blowing mechanism 12, a spraying and blowing pipe 13, the high-pressure centrifugal fan 14, a control valve 15 and a discharge pneumatic diaphragm pump 16.

Description

technical field [0001] The embodiments of the present invention relate to the field of machinery, and in particular to a continuous powder conveying device with a drying function. Background technique [0002] Due to the requirements of the environment and the health of workers, many powder materials, especially fine powder materials, are conveyed by pneumatic conveying in order to reduce dust pollution. At present, the pneumatic conveying of powder materials is generally driven by blowers, and adopts one-to-one positive and negative pressure, many-to-one negative pressure, one-to-many positive pressure feeding methods, or a combination of positive and negative pressure pneumatic conveying methods. However, whether it is a simple negative pressure, positive pressure or a combination of positive and negative pressure, the power of the blower required for long-distance transportation is relatively large. [0003] The existing powder material conveying device has a feeding sys...
