Description

A kind of grinding device for automatic intelligent sample-preparing system

Technical field

The utility model is related to arrive raw material and fuel quality to check and accept field, it is applied particularly to the materials such as iron ore, coal, sinter Full-automatic sample-preparing system grinding unit in, be that a kind of crushing and processing when being analyzed for laboratory assay or identifying quality are ground Mill apparatus.

Background technology

Three key links of sampling, sample preparation, chemical examination as inspection of quality, the direct shadow of automatization level of gathering and processing system It is horizontal to ring inspection of quality.Sample preparation between sampling and chemical examination, work rule be under the premise of not destroying sample representativeness, Collected sample granularity is gradually reduced, weight also gradually reduces, until meeting chemical examination to sample granularity and weight demands, system The granularity of prescribed requirement is answered uniformly and reached to standby sample, ensures that the material composition of whole primary sample and its content are constant.

Grinding is the support Unit to analytical test granularity in sample-preparing system, and theoretically sample must not have loss, and It must not occur physically or chemically to change, have larger impact to total precision, sample preparation precision, Error and Assay.With iron ore, sintering Mine, coal sample gather and process and turn to example, requirements of the national standard iron ore, sinter analysis sample granularity in 120 mesh or 150 mesh More than, the granularity of coal analysis sample is more than 80 mesh.

Currently, the grinding of material is all made of the semi-automatic operation of milling apparatus, tradition grinding single devices include mainly vibration Two kinds of forms of pulverizer or disc mill.When work, need manually to launch material, manual cleaning after grinding to grinder Sample may not apply in automatic intelligent sample-preparing system.

Vibrating pulverizer is a kind of high efficiency grinding equipment, and by material alms bowl, material alms bowl lid and hitting ring, hit block in material alms bowl is arranged Composition, in process, material alms bowl makees circumferentially forced vibration, material hit block, hit interannular be extruded, shear, hit, grind and It is pulverized, have many advantages, such as that powder processed is fast, material size is larger.But it is disadvantageous in that and only has at 2 per striking face in a flash, that is, hold Device inner wall and ring outer wall is hit, hits and ring inner wall and hits ring side（Theoretically analysis is the busbar that cylindrical surface is tangent at two）.Cause This, work(made by mechanical oscillation is not utilized fully, and there are a small amount of large particle material granularities after crushing（Sieving rate）It can not Meet chemical examination to require, artificial screening grinding need to be taken or repeatedly the ancillary measures such as mechanical grading grinding solve the problems, such as this.

Disc mill is one of designated equipment prepared by ore industry analysis sample, and groundwork executive item is by fixed Mill and movable grinding disc composition.Fixed millstone is connect with body, and movable grinding disc is connect with transmission main shaft, and fixed millstone engages to be formed with movable grinding disc Crushing chamber and abrasive disk space, material are crushed to required in crushing chamber high speed rotary motion by stressor layer and shearing force After granularity, gap is dished out between fixed millstone and movable grinding disc.

Disc mill is managed using laminated grinding and shear pulverizer, has the advantages that grinding is abundant, material can be by powder Broken is thinner, and granularity fully meets chemical examination and requires.But it is limited by structure type, there is also certain defects.For vertical disc Pulverizer（Mill face is parallel to horizontal plane）, material size requirement is thinner, and bulky grain cannot be introduced into disk, this is broken to preceding road Effect requirements are higher, need to take the ancillary measures such as artificial screening is roughly ground or multiple mechanical grading is broken；Horizontal disc is crushed Machine（Mill face is perpendicular to horizontal plane）, the rotation of movable grinding disc, which cannot achieve, drives all materials into mill to rotate therewith, The clearance fine adjustment of mill is more demanding, and part pan feeding is not ground directly to skid off disk, this partial material needs underhand polish to institute Need granularity.

Currently, the grinding unit for being applied to automatic intelligent sample-preparing system in the market largely crushes dress for band sieve vibration It sets, which increases sieve corresponding with chemical examination granularity requirements, crushing material to required granularity on conventional vibration pulverizer Enter discharge port discharge automatically by sieve afterwards, the material continuation for not meeting granularity requirements crushes in expecting alms bowl, until completely logical Sieve is crossed, process of lapping terminates.The problem of which solves conventional vibration pulverizer material sizes, but have the following disadvantages：

1）Sieve blocks：Water adaptability is poor, and the larger material of viscosity, which is easily adhered on sieve, blocks sieve pore, causes Screening efficiency reduces, and is crushed excessively so as to cause material or occurs to go bad, influences laboratory accuracy.

2）Collection rate is low：Although can be inhaled by negative pressure or the modes such as positive pressure is blown are cleared up defective material on sieve and grinding chamber and arranged Go out, with dust pelletizing system rejected material, but still can not ensure that cleaning is complete, and theoretically remaining material cannot abandon, and otherwise can break The representativeness of bad material.

3）Lack of homogeneity：Material has been subjected to selective layering by the way of grinding and sieving, has affected the equal of sample Even property, it is necessary to increase evenly mixing device.

4）The degree of automation is not high：Sieve needs frequently artificial replacement, is unfavorable for the long-term automated operation of system.

In conclusion oscillating mill and disc mill are applied individually to any automatic intelligent sample-preparing system, do not have certainly It is dynamic to complete, unattended function；Market novel belt sieve vibration grinding device is because collection rate is low, excessively broken, sieve blocks, sample The problems such as representative poor, it also cannot be satisfied the automatic intelligent sample-preparing system of high-precision sample preparation requirement.Grinding unit is intelligence The key that full-automatic sample-preparing system is realized the characteristics of for existing oscillating mill and disc mill, need to be efficiently modified.
