The flotation power performance measurement mechanism and the measuring system that respectively the utility model embodiment are provided are below described in detail.
(1) flotation power performance measurement mechanism
As depicted in figs. 1 and 2, a kind of flotation power performance measurement mechanism, its concrete structure can comprise: transparent observation body 1, stopple coupon 2, collection are surveyed cylinder 3 and image capture device 5; The inside of transparent observation body 1 is provided with observation chamber 13; Stopple coupon 2 is located at the bottom of transparent observation body 1, and the top of stopple coupon 2 is communicated with described observation chamber 13; Collect and survey the top that cylinder 3 is located at transparent observation body 1, and the bottom of collection survey cylinder 3 is communicated with described observation chamber 13; Collection is surveyed cylinder 3 and is provided with the first waterline L1 and the second waterline L2, and the place height of the first waterline L1 is greater than the place height of the second waterline L2; Image capture device 5 is fixedly connected with transparent observation body 1, and the image acquisition scope of this image capture device 5 comprises observation chamber 13, for gathering bubble diagram picture or the bubble image sequence in observation chamber 13.
Particularly, this flotation power performance measurement mechanism is for measuring the bubble diameter of target measurement point on flotation machine and inflation rate, and its measuring method specifically can comprise the following steps:
Particularly, to the intracontour waterflooding of this flotation power performance measurement mechanism, can adopt man-made injection, also can adopt pump series products (such as centrifugal pump etc.) water filling; But in order to guarantee higher water-injection efficiency, and control in order to realize the robotization of the injecting process, therefore preferably adopt the water filling of pump series products.In addition, the intracontour waterflooding to this flotation power performance measurement mechanism can, using the bottom mouth of pipe of stopple coupon 2 as water filling port, also can arrange a water filling port at the top of collection survey cylinder 3; But in actual applications, because follow-up measuring process need to make the bottom mouth of pipe of stopple coupon 2 always lower than clear water liquid level or mineral syrup liquid in flotation machine, and water natural flow from top to bottom under Action of Gravity Field is more saved the energy, therefore the top that is preferably in collection survey cylinder 3 arranges a water filling port, and a sealed valve (for example: sealing valve can be the first valve 41) that this water filling port can be sealed is preferably set at this water filling port place; When intracontour waterflooding to this flotation power performance measurement mechanism, sealing valve, can be to water filling in this water filling port in open mode; When the inside of this flotation power performance measurement mechanism is filled with after water, sealing valve can be adjusted to closed condition, and by this water filling port sealing, extraneous gas and water all cannot enter into this water filling port, thereby can make this flotation power performance measurement mechanism can not be subject to the impact of extraneous gas, and then accurately and reliably the inflation rate of flotation machine and bubble diameter be measured.
Particularly, therefore because being measures the inflation rate of flotation machine and bubble diameter, only have and in flotation machine, have clear water or ore pulp, and the target measurement point of selecting is also positioned under clear water liquid level or under mineral syrup liquid, just bubble can be collected, and then measuring process could be realized.
Particularly, because needs are collected the bubble through target measurement point, just can measure inflation rate and the bubble diameter of this target measurement point, therefore, in whole measuring process, the bottom mouth of pipe of stopple coupon 2 must be always lower than clear water liquid level or mineral syrup liquid in flotation machine.Owing to being inflation rate and the bubble diameter that the bubble that passes through target measurement point by collection is measured this target measurement point, therefore must accurately collect each bubble through target measurement point, guarantee obtains a measurement result accurately and reliably.
Particularly, corresponding image capture device 5 can adopt camera, the video camera that can buy by commercial means in prior art or the first-class image capture device of making a video recording, and can be also according to the principle of conventional images collecting device and the homemade image capture device of processing technology; Corresponding bubble image sequence can be several bubble diagram pictures, and a bubble diagram that also can jointly be comprised of several continuous air bubbles images is as sport video; It can be that artificial naked eyes set that bubble diagram picture or bubble image sequence are carried out to image recognition processing, also can on this flotation power performance measurement mechanism, an embedded image treatment facility be set identifies, this bubble diagram picture or bubble diagram can also be arrived to the remote image analytical equipment (for example: this remote image analytical equipment can be image analysis apparatus 9) of this flotation power performance measurement mechanism outside as sequence transmission, then be identified by remote image analytical equipment.In order to improve the accuracy of image recognition result, outside surface at transparent observation body 1 can arrange rule, the image acquisition scope of image capture device 5 comprises this rule, by image or the image sequence of this rule of gathering simultaneously, and the bubble diagram picture in observation chamber 13 or the bubble diameter that bubble image sequence can be determined this target measurement point more exactly.
Particularly, because inflation rate is the volume of air that in flotation machine, on every square metre of liquid level, per minute is overflowed, and for each target measurement point, the volume of air that this target measurement point per minute is overflowed equals the volume that collection is surveyed cylinder 3 interior discharged water, if therefore represent that with Jg (its unit is m to inflation rate
3/ (m
2min)), with V, represent that (its unit is m to the volume that collects survey cylinder 3 the second waterline L2 by the first waterline L1
3), (its unit is m with S, to represent to survey the cross-sectional area of cylinder 3 by collection
2), with L, represent by the first waterline L1 to the distance (its unit is m) the second waterline L2, with T, represent to drop to the required time swap of the second waterline L2 (its unit is min) by the first waterline L1, with t, represent to drop to the required time swap of the second waterline L2 (its unit is s) by the first waterline L1, can obtain following equation so:
Obviously, the water surface elevation of surveying in cylinder 3 according to collection drops to the required time swap of the second waterline L2 by the first waterline L1, and first difference in height between waterline L1 and the second waterline L2 just can determine the inflation rate of target measurement point, therefore can measure in advance the difference in height between the first waterline L1 and the second waterline L2, and record set is surveyed water surface elevation in cylinder 3 and is dropped to time of the first waterline L1 and collection and survey the time that water surface elevation in cylinder 3 drops to the second waterline L2 respectively, just can determine the inflation rate of target measurement point; This process can manually complete, also can be completed voluntarily by embedded device, for example: at the first waterline L1 and the second waterline L2, a level sensor can be set respectively, and on this flotation power performance measurement mechanism, an embedded device can be set, this embedded device is processed the inflation rate that just can calculate target measurement point by the electric signal that two level sensors are obtained.
Particularly, step 6 is not steps necessary, for example, when this flotation power performance measurement mechanism comprises display module (: this display module can comprise LCDs), can make display module that the bubble diameter of this target measurement point and inflation rate are represented to user.
