Description
Technical field
The utility model belongs to the ore separators auxiliary device, the on-line automatic dynamic density analyser of particularly a kind of flotation pulp foam.
Background technology
In ore dressing flotation production run, the quality of ore pulp froth bed thickness and foam is that technology is adjusted very important parameter in the flotation cell.Up to the present, owing to there is not effective detection method, operating personnel can only be by the on-site experience analysis, very inaccurate, cause maloperation easily, adopt ultrasonic level gage, radar level gauge and floating ball lever meter to detect mineral pulp level in the flotation cell in the world, but be used for ultrasonic level gage, the radar level gauge transmitted wave can't penetrate froth bed, measure inaccurately, floating ball lever meter can't overcome pulp density and change influence to measuring liquid level, measures inaccurate.Because present neither one is in the world measured the quality effective ways of interior ore pulp froth bed thickness of flotation cell and foam, so all ore dressing plant flotation flowsheets still can not realize the whole process closed-loop control in the world.
Summary of the invention
The purpose of this utility model provides the on-line automatic dynamic density analyser of a kind of flotation pulp foam, intuitively show by the micro-variations of foam analysis instrument on-the-spot foam, the thickness, the quality that show foam, carry out trend analysis, that further judges each section operation scrapes the blister attitude, so that carry out technological operation, improve flotation operation efficient and quality.
The purpose of this utility model realizes by following technical proposals:
According to the on-line automatic dynamic density analyser of flotation pulp froth bed of the present utility model, it is characterized in that by sniffer, the spiral lift device that is connected of sniffer therewith, with sniffer therewith respectively, the control device that spiral lift device is connected is formed, described sniffer is by the counterweight detector, the steel wire that is connected of counterweight detector-pulling force sensor is formed therewith, this steel wire-pulling force sensor is connected with the lower end of spiral lift device, described control device is by the Switching Power Supply that is contained in the control casing, the PLC template, terminal row and liquid crystal touch screen are formed, the PLC template is connected with terminal row with liquid crystal touch screen respectively, terminal row respectively with described pulling force sensor, spiral lift device connects.
Described spiral lift device is by helical screw, the speed gear that is connected of helical screw therewith, and the uniform speed electric motor that is connected of speed gear and the limit protection device that is located on this uniform speed electric motor are formed therewith.
Described liquid crystal touch screen is contained on the door of control box.
Adopt the utility model can realize online automatic dynamic density analysis, trend by the foam analysis instrument changes, can the micro-variations of on-the-spot foam be shown intuitively, the thickness and the quality that show foam, improve flotation operation efficient and quality, be applicable to various technics of metallurgy mineral dressing factory, help the ore dressing plant to realize the production automation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1, according to the on-line automatic dynamic density analyser of flotation pulp froth bed of the present utility model, it is characterized in that by sniffer, the spiral lift device that is connected of sniffer therewith, with sniffer therewith respectively, the control device that spiral lift device is connected is formed, described sniffer is by counterweight detector 1, the steel wire 2 that is connected of counterweight detector 1 therewith, pulling force sensor 3 is formed, this connects pulling force sensor 3 and is connected with the lower end of spiral lift device 8, described control device is by the Switching Power Supply 11 that is contained in control box 10 bodies, PLC template 12, terminal row 13 and liquid crystal touch screen 9 are formed, PLC template 12 is connected with terminal row 13 with liquid crystal touch screen 9 respectively, terminal row 13 respectively with described pulling force sensor 3, spiral lift device 8 connects.
Described spiral lift device is by helical screw 4, the speed gear 5 that is connected of helical screw 4 therewith, and the uniform speed electric motor 6 that is connected of speed gear 5 and the limit protection device 7 that is located on this uniform speed electric motor 6 are formed therewith.The limit protection device 7 couples of uniform speed electric motors 6 shield.
Described liquid crystal touch screen 9 is contained on the door 14 of control box 10.
When adopting the utility model, at first connect the Switching Power Supply in the control casing, the PLC template brings into operation, uniform speed electric motor in the control spiral cabinet just changes, the uniform speed electric motor drives the helical screw rotation by speed gear, the counterweight detector that helical screw drives on pulling force sensor and the connected steel wire at the uniform velocity enters froth bed from flotation cell foam top, and enter the ore pulp layer from froth bed, set the just commentaries on classics time of spiral lift device by the PLC template, the degree of depth that control enters the ore pulp layer, control the counter-rotating of spiral lift device behind the arrival set point by the PLC template, the counterweight detector enters froth bed by the ore pulp layer, top from the froth bed to the foam, the PLC template is back and forth carried out said procedure.In counterweight detector to-and-fro movement process, in time the pulling force signal is sent to the PLC template by pulling force sensor, carry out computing by the PLC template, pulling force is transformed into density value, the PLC template root point position that motor travelling speed, rotating working time and the automatic computing of operation stroke are measured of crouching simultaneously, signal is sent to liquid crystal touch screen, the trend that demonstrates thickness, amount of densities and the foam density of foam on liquid crystal touch screen changes, operating personnel just can in time understand the online dynamic density of flotation pulp froth bed, so that instruct production.
