As depicted in figs. 1 and 2, for by ash from the fixing assigned position of slideway (example of the grey mobile route) side wall portion along the vertical setting for the treatment of apparatus of grey storagetank guiding heavy metal, be formed with the peristome 1a of rectangle, and above-mentioned peristome 1a is connected with passage 2 with ash collection, this ash collection uses passage 2 for gathering the ash as sample.
Above-mentioned ash collection comprises with passage 2: take out channel part 3, one end along continuous straight runs and be connected with the peristome 1a of slideway 1; And passing away section 4, the mode of the other end to be communicated with this taking-up channel part 3 at above-mentioned taking-up channel part 3, vertically arrange downwards, in addition, as the rear side bottom wall part 3d of the coupling part of the side wall portion 4a of the bottom wall part 3c of above-mentioned taking-up channel part 3 and passing away section 4 for dipping down inclined-plane (can be also the arc surface of heaving to upside).
One end that in addition, below will take out slideway 1 one sides of channel part 3 is called front side and the other end of passing away section 4 one sides is called to rear side and describes.
Above-mentioned ash gathers with being provided with in passage 2 for gathering grey grey harvester (example of grey collecting device) 5 and an x-ray measurement device (example of x-ray measurement equipment, also referred to as the x-ray analysis device) 6, this x-ray measurement device 6 measure by above-mentioned grey harvester 5, collected as the heavy metal concentration in the ash of sample.
Above-mentioned grey harvester 5 comprises: overlook the supporting member 11 into the connection use of U-shaped, be configured to move in taking out channel part 3; Mobile with cylinder assembly (example of mobile device) 12, be arranged on the other end of above-mentioned taking-up channel part 3, the 12a of bar section is connected with above-mentioned supporting member 11 and makes this supporting member 11 channel part 3 is interior moves along fore-and-aft direction in taking-up; Ash gathers with container 14, and on the close openend position of above-mentioned supporting member 11, front end one side is supported for swing freely by the supporting pin 13 of horizontal direction; And the pole shape strike off member (example of smoothing member) 15, be arranged on coboundary one side of the peristome 1a of above-mentioned slideway 1, gather upper surface (the particularly upper surface of the aftermentioned container body section) planarization with container 14 for making ash.
In addition, it is upper that above-mentioned supporting member 11 is configured in bottom wall part (diapire face) 3c that takes out channel part 3 sliding freely, sometimes also the roller that can rotate can be set on supporting member 11 on bottom wall part 3c.
And ash collection comprises with container 14: overlook the frame shape section 16 into rectangle, front end one side utilizes above-mentioned supporting pin 13 to be supported for swing freely; The container body section 17 of box-shaped, be configured in front side and top the opening wide of above-mentioned frame shape section 16, in addition, the front side wall 17a of container body section 17 and rear side wall 17b tilt laterally, and at least rear side wall 17b is larger than grey angle of repose with respect to the tiltangleθ of pedal line.
And, utilize above-mentioned mobile with cylinder assembly 12, above-mentioned ash gather can be in slideway 1 with container 14 grey collection position (A) and the grey drain position (B) corresponding with passing away section 4 between move back and forth.
, as mentioned above, above-mentioned ash gathers with the leading section of the frame shape section 16 of container 14 and swings front end one side that is supported on freely supporting member 11, and rear end one side is supported on the bottom wall part 3c that takes out channel part 3, therefore, when the ash collection is mobile to the grey collection position (A) in slideway 1 with the container body section 17 of container 14, rear end one side of frame shape section 16 is supported on the bottom wall part 3c that takes out channel part 3 and goes up and keep flat-hand position, on the other hand, when container body section 17 is mobile to the grey drain position (B) in passing away section 4, because rear end one side of frame shape section 16 drops in passing away section 4 via the rear side bottom wall part 3d that takes out channel part 3, so container body section 17 becomes the vertical posture via the inclination mobile gesture.
And excessively slow if above-mentioned ash gathers by translational speed, the particularly haulage speed of container 14, Measuring Time is elongated, if too fast, can on surface scraping, crack the depression of shape, so velocity range is 0.1～0.5m/sec.
In addition, if the time that ash is gathered move to slideway 1 with container 14 (to slideway outstanding time) is short, can not gather fully ash, measuring accuracy is exerted an influence, if long Measuring Time is elongated, so, in order to reduce the measurement frequency, select reasonable time.
For example when the internal diameter of slideway 1 be 0.3m, while per hour falling 700kg grey, the scope that the preferred time is 30～120 seconds in order to gather the ash of measuring required q.s.In addition, if the internal diameter of slideway 1 is different with the amount of falling of ash, the above-mentioned time is also different.
Certainly, ash gathers the area that the size with container 14 is exposure while being suitable for measuring.
In addition, on above-mentioned grey collection container 14, for example on the side of container body section 17, be equipped with the vibration give device (ultrasonic oscillator) 18, give vibration for utilizing ultrasound wave.
For example, when gathering ash, by container body section 17, giving ultrasonic vibration, ash becomes tightr and uniform state, thereby has improved measuring accuracy.In addition, when discharging ash, container body section 17 is tilted mobile and while discharging ash, also can be by giving vibration, the ash in amount discharge container main part 17 reliably.
In addition, the position except container body section 17 that device 18 also can be arranged on grey collection container 14 is given in above-mentioned vibration, such as being installed on frame shape section 16 etc.
In addition, if the diameter that strikes off member 15 of above-mentioned pole shape is little, can not obtain grey densification effect (volume density diminishes) when ash gathers the drawing-in motion with container 14, in addition, need larger installation site if diameter is excessive, so its proper range is 10～30mm.
In addition, as mentioned above, in the upper wall portions 3a that takes out channel part 3 midway, be to be provided with peristome 3b between grey collection position (A) and grey drain position (B), and dispose above-mentioned x-ray measurement device 6 on above-mentioned peristome 3b.This position is called to ash measure position (C).In addition, the roentgen radiation x of above-mentioned x-ray measurement device 6 inserts above-mentioned peristome 3b with the 6a of window section and fixes this x-ray measurement device 6.
At this, x-ray measurement device 6 is briefly described, from irradiating with the 6a of window section to container body section 17 exposures of container 14 for the ash collection, to the exposure of the ash content as the measuring object thing that is stored in container body section 17, and inject x-ray measurement device 6 from the fluorescent x-ray of the material incentive that forms ash content, according to its intensity (count number) detection material amount, thereby measure the heavy metal concentration in ash.
That is, above-mentioned x-ray measurement device 6 at least possesses: the x-ray generating unit produces x-ray and penetrates to the measuring object thing; X-ray is injected section, injects the fluorescent x-ray by the excitation of measuring object thing; Intensity detection section, detect the intensity of the fluorescent x-ray of injecting in the above-mentioned x-ray section of injecting; And concentration calculating part, based on by the detected intensity of above-mentioned intensity detection section, detection is included in the amount of the heavy metal in ash and obtains its concentration, possesses in addition the surface state test section, this surface state test section is obtained by the full strength of the detected fluorescent x-ray of above-mentioned intensity detection section (full count number), and calculates the ratio c(c=a/b of the normal intensity value b under the above-mentioned full strength value a standard state in apparent good order and condition with respect to the measuring object thing).The ratio c obtained in above-mentioned surface state test section is during lower than predetermined threshold value, the not smoothing and produced error on measured value of judgement surface state.Not during smoothing, do not consider the heavy metal concentration of now measuring when the judgement surface state.In addition, about above-mentioned threshold value, by experiment, obtain accordingly full strength and measuring error now with various surface state, and full strength that will be corresponding with the measuring error that can allow is as threshold value.For example, the coordinate diagram of Fig. 3 means object lesson.According to above-mentioned coordinate diagram, when the full strength (count number) of fluorescent x-ray, when 900cps is above, measuring error becomes the scope of (limit that can allow) below 0.05%, and therefore, Threshold now is 900cps.
As mentioned above, container body section 17 from the slideway 1 that cuts off with outside, via the taking-up channel part 3 also cut off with outside to passing away section 4 one side shiftings.That is, ash gathers by passage 2 integral body becomes the closed structure separated with outside (system is outer).
In said structure, during heavy metal concentration in the ash in measurement drops to slideway 1, at first make the mobile 12a of bar section with cylinder assembly 12 outstanding, and it is mobile to the grey collection position (A) in slideway 1 from taking out channel part 3 that ash is gathered with the container body section 17 of container 14, at this, container body section 17 is interior that ash is stored into to chevron.
If become chevron through the stipulated time ash, utilize mobile with cylinder assembly 12, that container body section 17 is mobile to ash measure position (C) to taking out channel part 3 one side-linings.
During above-mentioned drawing-in motion, utilizing vibration to give device 18 gives vibration and makes ash become compact state to container body section 17, and utilize to strike off member 15 on the peristome 1a be arranged on slideway 1, remove the chevron part that becomes the ash of chevron in this container body section 17, so that it has an even surface.
Then, utilize x-ray measurement device 6, to container body section 17 internal radiation x-rays, measure the heavy metal concentration in ash.Now, the full strength value a that computation and measurement goes out is with respect to the ratio c(=a/b of normal intensity value b), and aforementioned proportion c and threshold value are compared to judge that whether surface state is good.When aforementioned proportion is lower than threshold value, the surface state in judgement container body section 17 poor (for example test portion deficiency, or surface cracks, the state of depression etc.) and produce error on measurement result, the above-mentioned heavy metal concentration of measuring is invalid.
If the measurement of heavy metal concentration finishes, again utilize the mobile cylinder assembly 12 of using, container body section 17 is rearward moved, finally mobile to grey drain position (B).
Again describe, container body section 17 locates at grey collection position (A) and ash measure position (C), at least rear end one side of frame shape section 16 is removed the bottom wall part 3c support of channel part 3, keep above-mentioned flat-hand position, but the rear side bottom wall part 3d as the supporting surface of the taking-up channel part 3 corresponding with passing away section 4 tilts, so as shown in the dummy line of Fig. 1, rear end one side of frame shape section 16 starts to descend, and finally frame shape section 16 whole tilted rearward move and become the vertical posture via the inclination mobile gesture.
Therefore, the ash be stored in container body section 17 drops in passing away section 4.And, when above-mentioned ash falls, give vibration owing to also utilizing vibration to give device 18 to container body section 17, and the tiltangleθ of the rear side wall 17b of container body section 17 is larger than grey angle of repose, so the ash in this container body section 17 is all discharged.
In addition, the heavy metal concentration of being measured by above-mentioned x-ray measurement device 6 is sent to the fixing treating apparatus (not shown) of heavy metal that is configured in rear operation, at this, provides the fixedly medicament for the appropriate amount of the ash of discharging from slideway 1.
In addition, in the above description, make container body section 17 become the vertical posture and ash is discharged from the inclination mobile gesture, as long as but making the pitch angle of rear side wall 17b is the angle that ash falls naturally, can not be also the vertical posture.That is, can be also the inclination mobile gesture.
In addition, in the above description, to utilizing deadweight to make container body section 17, be that frame shape section 16 rolls tiltedly mobile being illustrated backward, but also can install and hammer into shape by rear end one side in above-mentioned frame shape section 16, forcibly make it roll backward oblique movement.In addition, can prevent when being measured by the peristome 1a be arranged on slideway 1, the swing type switch lid that utilizes deadweight to swing being set in advance, the ash in slideway 1 enters ash and gathers with in passage 2.
In addition, as grey mobile route, slideway is illustrated, but also can in above-mentioned slideway, bypass channel be set, and measure and drop to (by) heavy metal concentration in ash in above-mentioned bypass channel.
According to above-mentioned self-operated measuring unit, due to being gathered with passage, ash with the slideway arranged along vertical, is connected in the horizontal direction, arrange and can pass in and out the ash collection container in slideway in above-mentioned ash gathers with passage, and the smoothing member that at least lower surface is semicircle shape is set, this smoothing member is stored in the ash collection ash content interior with container for striking off, in addition, make the radius of above-mentioned smoothing member lower surface in the scope of 5～15mm, make above-mentioned ash collection use the scope of the translational speed of container at 0.1～0.5m/sec, so will drop to along the ash in the slideway of vertical setting as measuring test portion, by simple structure, just can be easily and obtain reliably the ash of ormal weight.
In addition, owing in the ash collection, with vibration is installed on container, giving device, when gathering ash, ash closely is taken in container, so can utilize accurately x-ray to be measured.
In addition, after measuring heavy metal concentration, can ash collection be moved to the other end with container by utilizing to move with cylinder assembly, thereby utilize deadweight to the tilted movement of passing away section, therefore, can, by simple structure, by being stored in ash, gather with the discharge of the ash in container.
In addition, when discharging, also can give vibration to grey collection container by given device by vibration, thereby discharge ash reliably.
In other words, because the container body section that makes grey collection container passes in and out in slideway (grey mobile route) from peristome, and that utilizes the pole shape be arranged on above-mentioned peristome strikes off member (smoothing member), make the ash that is stored in container body section become compact state and make its surface smoothing, so after can be in the ash that vertical is fallen closely be taken into container body section, directly utilize x-ray measurement device (x-ray measurement equipment) to measure heavy metal concentration, therefore, for example with after using hydraulic pressure cuber formation test portion above-mentioned test portion is taken out from the hydraulic pressure cuber, the situation of carrying out the fluorescent x-ray inspection is again compared, can make structure very simple, and can realize alleviating x-ray and check required loaded down with trivial details work, and reduction installation cost.
