Description
Technical field
The present invention is a kind of to tilt screen cloth spin vibration sieve for the combined type that sample preparation is detected, belongs to food, coal, processing of crude drugs skill
Art field.
Background technology
With the continuous social and economic development, on the one hand in order to set up energy conservation type social development pattern, industrially need
Mineral resources are carried out efficiently developing and utilizing, such as colliery, so carrying out it that convenient and swift and result is accurate
Sample preparation detection it is very necessary.On the other hand, with the continuous improvement of people's living standards, the quality for life has higher
Pursuit, especially in food security and drug safety field, thus to the said goods carry out sample preparation detection have very great
Meaning.Screening equipment is essential equipment in sample making course, and the levels of precision of screening result directly determines that article is examined
Survey the degree of reliability of result.And still lack sieve instrument and equipment specifically designed for material sample preparation at present.The sample making apparatus that presently, there are
It is mostly heavy, it should not carry and manufacturing cost is higher, cause sample preparation slowly, the problems such as sieving not thorough result in indirectly
Testing result is inaccurate, and the screening efficiency of equipment still has much room for improvement at present.So, design one kind is dedicated for material sample preparation
The device of screening seems very necessary.
Existing conventional screening plant mainly has three kinds：
（1）Gravity flow screen
Gravity flow screen is divided into two kinds of gravity flow screen lattice and strip-type screen.Diagrid sieve aperture is generally square or circle, and bar shaped screen hole is generally sieve
Seam;Compass screen surface angle is generally between 25 degree to 85 degree；Working portion is fixed, is slided by material along working face and obtains material
To screening.Static grizzly be ore dressing plant apply more one kind, be generally used for coarse crushing or in it is broken before prescreening.It is tied
Structure is simple, easily manufactured.Power is not consumed, directly ore can be discharged on compass screen surface.Major defect is that productivity ratio is low, screening efficiency
It is low, typically only 50-60%.
（2）Vibratory sieve
Structure of Vibrating Screen is made up of four parts, dither motor, one-level static grizzly and two grades of classification static grizzlies, vibration bullets
Spring and casing.Compass screen surface gradient is inversely proportional with screening screening percentage, and compass screen surface gradient is bigger, and flowing velocity is faster.Vibratory sieve is tied with it
Structure is simple, disposal ability is big, reliable operation the advantages of had overwhelming superiority in all screening plants, its occupancy volume is about
95%, but still lack the screening plant dedicated for sample preparation so far.
（3）Moving screen
The operation principle of moving screen：The operating mechanism of roller picker is arranged in parallel in the horizontal plane by several screen axis, and each screen axis is pressed
Same direction rotates, and material is travelled forward along compass screen surface.Material is conveyed simultaneously, and the particle of screen slot size is less than in material from screen slot
In fall, the particle more than screen slot size is stayed on compass screen surface and continued to move along, and is fallen in material collecting device, has the disadvantage to take
Space is larger, is not suitable for small-scale sample preparation screening.
The content of the invention
The invention overcomes the deficiencies of the prior art, and provides a kind of combined type inclination screen cloth detected for sample preparation
