Abstract

The utility model relates to a miniature homogenizing storeroom which belongs to the technique of power engineering. The utility model is mainly used for homogenizing powdery materials during cement manufacture and can also be used for homogenizing materials of other fields. The utility model is composed of a storeroom wall 1, an exhaust opening 2, a material inlet pipe 3, a material distributing cone 4, a central pipe 5, an inlet hole 6, a ventilation layer 7, a loose air hole 8, a loose air bin 9, a central air pipe 10, a material unloading pipe 11, a check valve 12, etc. The utility model can increase homogenizing rate and save electricity consumption.

Description

Small-sized homogenizing storehouse

A kind of small-sized homogenizing storehouse relates to the powder technology technology, is mainly used in the homogenizing of granular material in the manufacture of cement.The homogenizing that also can be used for other field material.

Manufacture of cement, particularly little manufacture of cement, of poor quality, the energy consumption height, its major cause is the key link of technological process: homogenizing, calcining, bistrique batching etc. are backward in technique.Calcining, bistrique batching etc. all have improvement in various degree in recent years, and homogenizing technology is then comparatively backward, just blows into from the bottom in cartridge type storehouse, when top material falls, it is stirred, thus the homogenizing material, but this mode homogenization efficiency is low, power consumption is higher, has influenced the quality of cement.

The purpose of this utility model is to design a kind of later-model small-sized homogenizing storehouse, thereby improves the homogenizing rate, saves power consumption.

Accompanying drawing is a structural representation of the present utility model.

As shown in drawings, the utility model is by storehouse wall 1, exhaust outlet 2, feeding pipe 3, material distributing cone 4, central tube 5, manhole 6, air-permeable layer 7, loosening wind hole 8, loosening wind storehouse 9, central air hose 10, discharge duct 11 and non-return valve 12 etc. partly consists of, and wherein the top of storehouse wall 1 has exhaust outlet 2, feeding pipe 3 inserts in the storehouse from the center, top in storehouse, its underpart is connected with a material distributing cone 4, and there is a central tube 5 in the centre in the storehouse, below of material distributing cone 4, and the lower wall of storehouse wall 1 has manhole 6, there is a central air hose 10 that is interlinked to the outside with the storehouse below of central tube 5, non-return valve 12 is arranged in it, and the air-permeable layer 7 of an inverted cone shape is arranged at the bottom in storehouse, forms the loosening wind storehouse 9 of annular between the bottom of air-permeable layer 7 and storehouse wall 1, the sidewall in loosening wind storehouse 9 has loosening wind hole 8, and discharge duct 11 is arranged at the bottom in storehouse. The space that described material distributing cone 4 and feeding pipe are 3 is adjustable, manhole 6 can be opened with the person who happens to be on hand for an errand and enter interior maintenance, air-permeable layer 7 is linked to be by the ventilative material of densification (such as woven dacron etc.) piecemeal, loosening wind hole 8 has two, respectively to the loosening wind storehouse 9 interior air-supplies of two annulars, non-return valve 12 so that central air hose 10 during to central tube 5 air-supply material can not flow into central air hose 10.

During the utility model work, in the storehouse, feed intake through material distributing cone 4 from feeding pipe 3 earlier, material falls to reaching when a certain amount of blows to two loosening wind storehouses 9 in respectively by two loosening wind holes 8, this wind makes that by air-permeable layer 7 material of bottom of the reservior portion is loosening, make fluidization of material, dry at a high speed to base pipe 5 from central air hose 10 again, form negative pressure at base pipe 5 lower port places, make the fluidized material in the storehouse flow into base pipe 5 automatically, and taken to the top in storehouse by the wind that central air hose 10 blows out, and exit above base pipe 5, the lower cone that material is run into material distributing cone 4 carries out sub-material and falls, toward and renew, until material by homogenizing.Gas unnecessary in the storehouse is discharged by exhausr port 2.Behind the matter homogenizing, central air hose 10 is out-of-blast, opens discharge duct 11 and gets final product discharging.

The utility model is according to storage capacity (as less than 70 tons) and by the difference of homogenizing material, and the wind speed that central air hose 10 blows out is 6～8M/S, and blast is 4000～6000mm water column.

After the utility model was implemented, for 40 tons storehouse, through 1.5～2 hours homogenizing, homogenizing rate (promptly putting the ratio of material standard deviation and the standard deviation of outbound material in storage) reached 3～13.Integrated power-saving effect after the utility model is implemented sees the following form.
