Abstract
The utility model discloses a kind of online Ash analysers of X-ray being installed on before vibrating screen, including x-ray detection device and control system, x-ray detection device include x-ray source, X-ray linear array detector and X-ray radiation protective device.X-ray source and X-ray linear array detector are vertically opposite, are fixed on the both sides of chute before sieve, and the ray penetrating region of chute opens up non-metallic material ray window and carries out X-ray detection before the sieve.X-ray radiation protective device carries out radiation protection to entire detecting system.The control system is connect with x-ray source, X-ray linear array detector by wired mode, and the entire detecting system of control and output testing result are responsible for.Before the online Ash analyser of X-ray is mounted on vibrating screen, it ensure that the uniformity of tested material, improve accuracy of detection, reduce power consumption, while reducing radiation protection difficulty.
Description
Technical field
The utility model belongs to coal online measuring technique field, and in particular to a kind of X-ray being installed on before vibrating screen
Online Ash analyser.
Background technology
Coal is made of combustible and noncombustibles, pit ash refer to coal at a certain temperature fully, after completely burned not
Ratio shared by the residue of combustible.Traditional coal ash detection method is usually artificial sample chemical examination ash content, this people
Time-consuming for work detection method, cannot be detected in real time to coal sample ash content, is unfavorable for instructing the production of coal preparation plant.
Since the nineties in last century, there are the research and development of the online ash content tester of gamma-rays successively, is applied to Raw Coal
Or the ash content on-line checking of coal preparation product, to instruct the production of coal preparation plant.General online Ash analyser is installed on belt conveyor,
For detecting material ash content, but since the uniformity that the thickness of material on belt conveyor and ash content are distributed is poor, often make
Testing result is bad and without representativeness；In addition, since the material on belt conveyor is usually thicker, small-power penetrates source can not
Meet detection demand, it is necessary to penetrate source using high-power, the difficulty for penetrating source radiation protection is also increased while increasing power consumption.
Invention content
The technical problems to be solved in the utility model is, for existing online grey sorting-detecting instrument above shortcomings, to carry
For a kind of online Ash analyser of X-ray being installed on before vibrating screen, before the online Ash analyser of X-ray is mounted on vibrating screen, protect
The uniformity for having demonstrate,proved tested material improves accuracy of detection, while reducing power consumption, reduces radiation protection difficulty.
Used technical solution is the utility model in order to solve the above problem：
A kind of online Ash analyser of X-ray being installed on before vibrating screen, including x-ray detection device and control system, X-ray
Detection device includes that the x-ray source that can emit dual-energy x-ray, the X-ray linear array detector for receiving X-ray and X-ray radiation are anti-
Protection unit.X-ray source and X-ray linear array detector are vertically opposite, are fixed on the both sides of chute before the sieve of vibrating screen, before the sieve
The ray penetrating region of chute opens up non-metallic material ray window and carries out X-ray detection.Material through vibrating screen discharge end discharge after,
Chute before into sieve, the non-metallic material ray window opened up from ray penetrating region continue through.X-ray radiation protective device pair
Entire detecting system carries out radiation protection.The control system is connected with x-ray source, X-ray linear array detector by wired mode
It connects, is responsible for the entire detecting system of control and output testing result.
The utility model brings following advantageous effect：Before the online Ash analyser of X-ray is mounted on vibrating screen, it ensure that
The uniformity of tested material, improves accuracy of detection, secondly as vibrating screen discharging is relatively thin, the online Ash analyser of X-ray need to only make
Testing requirements can be met by penetrating source with small-power, reduce power consumption, while reduce radiation proof difficulty.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In Fig. 1：Chute, 3-X radiographic sources, 4-X rays linear array detector, the protection of 5-X ray radiations before 1- vibrating screens, 2- sieves
Device, 6- non-metallic materials ray window, 7- control systems
Specific implementation mode
1 pair of the utility model is further described below in conjunction with the accompanying drawings, but they are not to be protected to the utility model
The restriction of range.
As shown in Figure 1, a kind of online Ash analyser of X-ray being installed on before vibrating screen, including x-ray source 3, X-ray linear array
Detector 4, X-ray radiation protective device 5, control system 7.
The operation principle and the course of work of the online Ash analyser of X-ray being installed on before vibrating screen are as follows：
Material from the discharge end of vibrating screen 1 discharge after, into sieve before chute 2, the non-metallic material opened up from ray penetrating region
Continued through at matter ray window 6, at the same x-ray source 3 emit X-ray penetrate material after, connect by X-ray linear array detector 4
It receives, then the signal received is input in control system 7, is computed the ash value for obtaining material, it is finally that ash value is defeated
Go out to display interface.In whole work process, X-ray radiation protective device 5 carries out radiation protection to entire detecting system.
According to the disclosure and teachings of the above specification, the utility model those skilled in the art can also be to above-mentioned skill
Art scheme is changed and is changed.But the utility model is not limited to above-mentioned specific technical solution, every this field skill
Made any conspicuously improved, replacement or modification belongs to the utility model to art personnel on the basis of the present invention
Protection domain.In addition, although having used some specific terms in this specification, these terms are merely for convenience of description,
It does not limit the present invention in any way.
