High-fluidity flame retardant feeding device

Abstract

The utility model relates to the technical field of material conveying, in particular to a high-flowability flame retardant feeding device. As the fire retardant subjected to surface activation is good in flowability, in the charging process, excessive instant material supplementation is easily caused, the upper limit of material supplementation is exceeded, and charging is inaccurate; in addition, due to too fast material supplement and powder impact, a weight acquisition signal of the metering scale is also influenced, air pressure in the scale and dust floating are influenced, and the precision of the metering scale is reduced; when the metering scale is empty, a gap is formed between the screw rod and the sleeve, and the fire retardant is easy to rush out of the metering scale due to good flowability. According to the utility model, through the cooperation of the material storage tank, the material supplementing valve and the speed control device, the blanking speed of the flame retardant is uniform, the fluctuation of the metering scale and the inaccurate feeding caused by the high fluidity of the flame retardant are greatly reduced, and the reduction of the precision of the metering scale caused by the impact and floating of dust is effectively avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a high-flow flame retardant feeding device. Background Art

[0002] Flame retardants possess excellent fluidity due to their surface activation, making them easier to process and apply in polymer materials such as plastics, rubber, and fiber. However, due to the high fluidity of surface-activated flame retardants, the addition process can easily lead to excessive feeding, exceeding the upper limit and causing inaccurate feeding. Furthermore, due to excessively rapid feeding, the powder impacts the weight signal collected by the weighing scale, affecting the air pressure within the scale and causing dust to drift, resulting in reduced scale accuracy. When the weighing scale is empty, there is a gap between the screw and the sleeve, and due to the high fluidity of the flame retardant, it can easily burst out of the weighing scale.
