Description

Funnel flow type homogenizer

The present invention relates to a kind of being installed in can be to carrying out the homogenizer of equal equalization during the material discharging in the material storehouse in it.

In industries such as building materials, metallurgy, chemical industry, often need to solve the material that is stored in the material library is carried out equal equalization, this process requires to finish when getting material or discharging generally speaking.

In the existing material library, be applied to granular material, a main class is a batch (-type) air homogenizing storehouse, also be with the mixing device homogenizing process ＂ (" cement mill powdery homogenizing " of ascending pipe just like ＂, China Construction Industry Press, in July, the 1986 the first edition first impression, P254～256) and the research of ＂ mozzle clearance-type homogenizing storehouse and use ＂ (" Shanxi architecture " 1991 the 4th phase P12～17); Another kind of is continuous homogenization silo, and ＂ shear flow raw material machinery homogenizing storehouse ＂ (" cement " 1989.N0.12.P39～42).The homogenization efficiency of this two classes homogenizing storehouse is all than higher, but its one-time investment is big, consumption gas consumption electricity, must be equipped with the dust collection device system of corresponding specification in addition; Over-the-road expense is also bigger, and as batch (-type) air homogenizing storehouse, powder homogenizing per ton uses consumption of current between 0.4～0.7KWH.

The homogenizing storehouse that is used for the piece granular material in the prior art, it mainly is a kind of rectangle storehouse, as the pre-homogenizing storehouse ＂ of the small-sized raw material of ＂ (" cement " 1988 4 phase P27～33), it is by several discharge buckets under storehouse mode of discharging successively, be intended to implementation of class like in the pre-homogenizing stacking yard of rectangular chevron pointing, cut material to reach homogenizing from section, this scheme has certain effect.But because no any homogenizer in the storehouse only depends on limited several discharge buckets discharging operation successively, so in fact the section process that cuts material flows mechanism by single funnel and is replaced; Because the material library capacity is big, though the discharge bucket number is more more than common round storehouse, storehouse shape and distributing mode are also variant, but still are the big funnel ＂ of a kind of ＂ formula discharge methods,, its funnel is better than common round storehouse simultaneously though flowing homogeneization, but still and it is insufficient.This defective is difficult to remedy by the mode that rolls up funnel quantity on the one hand, and rolling up objectively of funnel quantity do not allow under normal conditions simultaneously.

In addition, above-mentioned two class homogenizing storehouse of powdery and piece granular material being carried out homogenizing; Have nothing in common with each other from version to equipment, both can not be general.

In order to overcome the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of funnel flow type homogenizer that is installed in the material library, powdery in the rate or piece granular material by gravity are finished the homogenizing operation process during by this device naturally.

To achieve these goals, the technical solution used in the present invention is: funnel flow type homogenizer, it presses the material library amount of capacity and shape constitutes the unit funnel with the unit plate, each funnel middle part, unit constitutes the streams passage from top to bottom, space in the spacing of each unit funnel constitutes material can divide mouth from the almost comprehensive serial charging that enters of unit funnel peripheral extent, this charging divides and mouthful communicates with described streams passage, thereby material mouthful enters the streams passage from described serial charging branch and moves from top to bottom and finish the homogenizing operation process in the storehouse in.

According to different storehouse types, corresponding homogenizer is set, and as to the rectangle storehouse, homogenizer can be arranged at the side-walls of each discharge bucket or the central part of discharge bucket, the homogenizer at wherein initial discharge bucket position should stretch out or near charge level, and is fixed on material storehouse top board or the sidewall; For the circle storehouse, be arranged in the homogenizer of discharging opening central part and, be arranged in the homogenizer at wall place, storehouse and pay part as homogenizing as the homogenizing main part, main part with pay the homogeneization that part plays separate homogenizing and compensation homogenizing simultaneously.

Compared with prior art, the present invention has outstanding substantive distinguishing features and significant technological advance, and its technical advance mainly shows in the following areas:

1. homo-effect is obvious: because it has changed material is only got in common round storehouse or rectangle storehouse from the bottom of the reservior discharging opening simple homogenizing mode, replace the three-dimensional material homogenizing of getting of section entirely of material in the storehouse, and strengthened the ＂ funnel greatly and flowed the ＂ leveling effect, so homo-effect is better than general gravity homogenizing, its homo-effect is looked into storehouse material fluctuation situation and difference, homogenization efficiency is 3～10, and the then raising of favourable homogenization efficiency is used in many storehouses:

2. obvious energy conservation: because the matter homogenizing process is also carried out in the common discharging process thereupon, need not special homogenizing consumption of power, the homogenization process that the present invention realized comes down to a kind of unpowered homogenizing operation process;

3. applicability is strong: the present invention both can be used for piece granular material homogenizing also be can be used for the homogenizing to granular material;

4. reduced investment, easily enforcement: the present invention both can be applicable in the newly-built storehouse, can be applicable to the transformation in old storehouse again, need not increase construction investment newly, also not change under the situation of original material storehouse charging and discharging equipment, implement the present invention and just can make common material storehouse have the dual-use function of storage and homogenizing concurrently.
