Description
Technical field
The utility model relates to the preparation facilities of a kind of particle or granular material sample, specifically relates to a kind of coal sample and divides the division of getting device, particularly relates to a kind of rotary dividing device.
Background technology
Division is in the situation that the constant quality that reduces of granularity is checked required coal sample quality to reduce the follow-up work amount and to reach at last.When a certain granularity, possible division once, also the continuous division several times of possibility just can reach the minimum amount of keeping sample under this granularity, the sample preparation error is mainly come to this operation steps, therefore the amount of keeping sample in each division stage must meet the granularity of stipulating in standard and the relationship between quantities that keeps sample, otherwise is difficult to guarantee division precision.In the coal sample preparation, the method for division mainly contains artificial coning and quartering, riffle division method, division method, chessboard division method and mechanical division methods at 9.For making coal sample representative, division is the main link that produces error.
Machinery division method adopts reduction device to carry out division.Reduction device is powder and granule shape material to be carried out the solid separation sorting unit of high division ratio, is mainly used in the preparation of coal or other granule materials sample divider pass.Formed by motor, reductor, receiving hopper, revolving shaft etc.Rotary receiving hopper is in when revolution, cutting coal stream equably, division to coal sample drop in receiving hopper, and fall to sample divider by it, abandon coal and fall the feeding mouth of rejected material device through the inwall that tilts, thereby complete the division of sample.
On Vehicles Collected from Market, the reduction device that go out to be adopted has a variety of, roughly can classify as following four kinds: the rotating disk type reduction device, move back and forth hopper-type reduction device, belt scraper reduction device and the bucket type reduction device that re-packs.But all because of do not reach relatively large material by the time the desired division ratio of division and division precision, the especially division requirement under material amount 120Kg/ point when full column is sampled.For example, application number is 201210234766.7, and the applying date is 2012.07.09, and application publication number is CN102706718A, Shen Qing Publication day is 2012.10.03, denomination of invention is the application of " sampling division device ", and it adopts the disk reduction device, when material moisture is higher, drop on disk and easily harden, between disk card and material scraper, catching phenomenon occuring, and cause the change of disc level angle and the deformation of material scraper, makes the volume production that keeps sample give birth to larger error in the time of damage equipment.
With in the mechanical sampling of coal unit, sticking stifled, the division precision of the desired division of the sample preparation operation not technical barrier of bias is anxious to be resolved with coal unit especially Guizhou province for each.
Summary of the invention
The purpose of this utility model is to provide a kind of not sizing, sampling division device that degree of accuracy is high.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of rotary dividing device, it comprises frame, is located at the feed pipe of upper rack, the below that is positioned at feed pipe on frame is provided with inversed conical drum, the upper port of abandoning the sample elephant trunk penetrates in inversed conical drum and corresponding to the lower port of feed pipe, the top that is positioned at inversed conical drum on frame is provided with the turning axle that is driven by power, turning axle is provided with holds back plate, holds back between the lower port of the plate upper port by abandoning the sample elephant trunk and feed pipe in upper shed place of inversed conical drum and when rotation.
The utility model is for the ease of the intercepting sample, and the described plate of holding back is 2～8, is uniformly distributed on turning axle, and the height of holding back plate is 2 ㎝～400 ㎝, and the tactical diameter of holding back plate is 20 ㎝～200 ㎝.
The utility model is for fear of knot tying, sizing, and described longitudinal section of holding back plate is rectangle or U-shaped or V-arrangement or C shape or L shaped.
Owing to adopting technique scheme, the utility model has been realized goal of the invention preferably, the mode that it adopts rotation to re-pack, and sizing putty not, division ratio is stable, and the division degree of accuracy is high, has satisfied the requirement of the sample preparation operation in the mechanical sampling.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
As shown in Figure 1, a kind of rotary dividing device, it comprises frame 1, is located at the feed pipe 2 on frame 1 top, the below that is positioned at feed pipe 2 on frame 1 is provided with inversed conical drum 7, the upper port of abandoning sample elephant trunk 8 penetrates in inversed conical drum 7 and corresponding to the lower port of feed pipe 2, the top that is positioned at inversed conical drum 7 on frame 1 is provided with the turning axle 3 that is driven by power 4, turning axle 3 is provided with holds back plate 5, holds back between the lower port of plate 5 upper port by abandoning sample elephant trunk 8 and feed pipe 2 in upper shed place of inversed conical drum 7 and when rotation.
