Description
Technical field
This utility model relates to feeding device, particularly to a kind of pipe negative pressure feeding device.
Background technology
Colophonium is being modified or is revising in index process, realize typically via outer-penetrating agent additive, outer-penetrating agent separatory state and solid-state two kinds, wherein solid outer-penetrating agent includes SBS, rubber powder, stabilizer, performance enhancement, SBR powder, kir powder etc., and conventional solid outer-penetrating agent adds and is divided into artificial, scroll feeder, several feed way such as air conveying.
Hand stock: the outer-penetrating agent measured is promoted to storage tank charge door by operator, adds in batches.Adding procedure anthropic factor is many, it is difficult to ensure that uniformity, thus causing that outer-penetrating agent can not play its maximum effect.And hand stock safety is very poor, severe operational environment, the dust, the harmful gas that produce in adding procedure are more, very easily damage to operator.
Scroll feeder feeds in raw material: namely adopt screw conveying structure to be transported in storage tank by the outer penetration enhancer measured.Helical feed is applicable to the conveying of short-range material, and angled conveyor is unsuitable excessive, and when angled conveyor is bigger, transfer efficiency can be decreased obviously.Material performance is required significantly high by helical feed, very easily occurs that charging inequality even results in spiral blocking when carrying material particles relatively big or overloading；It addition, reinforced process is it is generally required to be one feeder of every configuration of storage tanks, enough working places need to be reserved in scene, is difficulty with automatic operating, and cost of investment is higher.
Air conveying reinforced: air conveying point of malleation conveying and negative pressure transportation two ways, it is necessary to consider that the factors such as eliminostatic are to ensure delivery safety.Air conveying exist the shortcomings such as energy consumption is big, abrasion is big, noise is big, and under isodose transport condition, energy consumption is 3-5 times of helical feed.Air conveying that material properties and conveying air velocity control requirement is higher, there is flying dust in various degree, cause environmental pollution.Relative to other mode of movements, air conveying structure is the most complicated, fault rate is high, cost of investment is high.
It is a very important link in Production Process of Modified Bitumen that solid outer-penetrating agent adds, and the quality of its addition manner directly influences the quality of modified pitch.Outer-penetrating agent addition needs accurate proportioning, uniformly adds to be beneficial to and produces qualified modified bitumen product.Current outer-penetrating agent add exist artificial interference factor too much, take time and effort, adding procedure also is difficult to ensure uniformity, affects product index.Therefore, seek a kind of reasonable and effective addition manner to be highly desirable to.
