Description

A kind of storage bin for inovulant particle screen selecting equipment

Technical field

The present invention relates to inovulant production field, be specifically related to a kind of storage bin for inovulant particle screen selecting equipment.

Background technology

The cocrystallizing type alloy that cast iron is made up of iron, carbon and silicon substantially, wherein, carbon mainly exists with the form of graphite; Produce premium casting, form and the parent metal tissue of the graphite formed when controlling cast iron solidified are vital; Inoculation is one of most important link in production technology; Good inoculation can make cast iron have satisfactory microscopic structure, thus ensures mechanical property and the processing characteristics of foundry goods; In liquid cast, add inovulant, a large amount of sub-micro-core can be formed, impel eutectic cell to generate in the liquid phase; During close to eutectic freezing temperature, first raw core place forms tiny graphite flake, and grows into eutectic cell thus; The formation of each eutectic cell, all peripherad liquid phase can discharge a small amount of heat, the eutectic cell of formation is more, and the freezing rate of cast iron is lower; The reduction of freezing rate, just contributes to solidifying by iron-graphite systems stabilisation, and can obtain A type graphite tissue.

Inovulant is that one can promote that graphite is formed, reduces chilling tendency, improves graphite form and distribution situation, increases the additive of eutectic cell quantity, refinement matrix, most popular 75 silicon iron inoculator at present.In casting process, molten iron in ladle has the high temperature of 1400 degrees centigrade, if have powder in inovulant, add in molten iron process can in surface oxidation and scaling loss, do not reach pregnant effect, usual inoculant products is the above particle of granularity 0.2mm, and below granularity 0.2mm is exactly ash loss, the more losses of dust generation are larger, and cost is higher; Again inovulant particle transport is completed screening to vibratory sieve mainly stir a period of time by man-handling of materials to agitator in the process of inovulant particle later stage screening pack after; if transporting velocity is too fast; vibratory sieve cannot complete screening; if transporting velocity is excessively slow; agitator is then needed to shut down a very long time; can not complete continuous seepage, efficiency is lower.

Summary of the invention

The object of the invention is to solve the problem, a kind of storage bin making production equipment continuous operation is provided.

For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of storage bin for inovulant particle screen selecting equipment, comprise at the bottom of Cang Gai, warehouse, storehouse, discharge port and support, the two ends up and down of warehouse are laid respectively at the bottom of Cang Gai and storehouse, discharge port is positioned at the bottom at the bottom of storehouse, storehouse tops is provided with breach, and support installing is in warehouse both sides.

Preferably, described warehouse and discharge port are box-like body.

Preferably, the spatial volume surrounded at the bottom of described Cang Gai, warehouse and storehouse is 2m ³.

Preferably, at the bottom of described Cang Gai, warehouse, storehouse, the material of discharge port and support is metal material.

Preferably, the quantity of described support is four.

In sum, storage bin provided by the present invention, between agitator and vibratory sieve, play storing and control inovulant particle transport speed, can ensure that agitator can be started shooting work having got rid of inovulant particle, also can ensure that the inovulant particle being transported to vibratory sieve is unlikely to excessive, add operating efficiency.
