Abstract

The utility model provides a sample grading drum screen and belongs to the field of material sorting. The sample grading drum screen comprises multiple grades of inclined rotating drum screen bodies which are arranged in sequence from a feeding port, wherein the numbers of meshes of the multiple grades of inclined rotating drum screen bodies are different. The sample grading drum screen is characterized in that each grade of drum screen bodies are divided into the inner-layer drum screen body and the outer-layer drum screen body, the number of meshes of each inner-layer drum screen body is smaller than the number of meshes of the corresponding outer-layer drum screen body, a discharging port is formed below the outer-layer drum screen body of each grade of drum screen bodies, and the drum screen bodies are connected with a rotation driving device. By the adoption of the sample grading drum screen, the inclination angle of the rotating drum screen can be increased, the screening speed can be increased, the labor intensity of workers can be relieved through an automatic control mode, production cost is reduced, and productive benefits are increased.

Description

A kind of sample classification drum sieve

Technical field

The utility model designs a kind of grading cylinder, and particularly a kind of sample classification drum sieve, belongs to material sorting field.

Background technology

In industrial production, can relate to a lot of granular materials or powder or raw material, and these materials are according to the difference of granular size, its purposes is all different, for product performance is understood, need to carry out in advance grading screening sampling, in existing sample classification process, the sieve utilizing is mostly reciprocating gird or drum sieve is unit single-stage sieve, this sieve screening efficiency is low, and need many complete equipments jointly to use, raw material could be sieved into different grades, inefficiency, labor strength is high, screening cost is also high, although there is at present multi-stage drum screen, but in use, because the order number of material inlet place screen cloth is larger, in sizing screening process, within the limited time, small size particle raw material is easily together taken in next stage screen cloth by bulky grain, make to screen undesirable, special needs after classification distributes calculate in the situation that to sample granularity, this granule that carries backward can cause error larger between data and reality, can also cause the further amplification to error of next step batching or other operation, therefore how can accurately sieve, obtain accurate granularity data, reduce screening cost, reduce labour intensity, increase work efficiency, it is the common hope of factory and workman.

Summary of the invention

High for reciprocating gird or cylinder unit single-stage sieve screening cost, labour intensity is high, ineffective problem, the utility model provides a kind of sample classification drum sieve, its object is exactly for workman is freed from do labour intensity, improves the economic benefit of factory.

The technical solution of the utility model is a kind of sample classification drum sieve, comprise the different Sloped rotating drum sieve of multilevel screen order number that starts to arrange in order from feed(raw material)inlet, it is characterized in that: described every grade of drum sieve is divided into inner layer cylinder sieve and outer drum sieve, described inner layer cylinder sieve sieve number is less than the sieve number of outer drum sieve, outer drum sieve at every grade of drum sieve is arranged with discharging opening, drum sieve is connected with rotating driving device, the sieve number of the outer drum sieve of next stage is identical with the order number of upper level inner layer cylinder sieve, described inner layer cylinder sieve is contrary or identical with the direction of rotation of outer drum sieve, described drum sieve is connected with rotating driving device, rotating driving device is provided with speed regulator.

The good effect the utlity model has is, by utilizing inner layer cylinder sieve and outer drum sieve, can make more abundant in front end screening of short grained sample, bulky grain sample carries the generation of granule sample situation backward, obtain classification sample and granularity data thoroughly, granularity error can be amplified in follow-up operation and production, be conducive to the accurate control of producing, one deck is screened to halfway particulate material to the utility model or powder reaches screening completely, owing to being two-layer screening, can comparatively significantly improve the angle of inclination of rotary screen, accelerate breakneck acceleration, utilize automatic control mode, can reduce workman's labour intensity, reduce production costs, improve productivity effect.
