Description
Technical field
The utility model relates to a kind of rotational flow microbubble floatation equipment, relates in particular to a kind of for obtaining low many concentrate of ash productFloatation equipment.
Background technology
Along with the continuous intensification of the exploitation of coal resources degree of depth and the deterioration of Resource geology condition, Coal Mechanical melts in additionAdopt the further raising of degree, cause slime content proportion in raw coal on average between 20% to 30%, the difficult choosing of high ash is thinBeans ratio presents the trend sharply increasing. Floating separation claims again flotation, be particulate and superfine particle material divide choose most widely used,A kind of beneficiation method that effect is best. According to the practical application in mining processing industry is produced at present, floatation equipment can be divided into twoLarge class: flotation device and flotation column. Because flotation column has better selectively than flotation device in the time processing superfine particle material, canObtain better industrial technology index, the application of flotation column more and more causes people's concern. In actual production, wantThe ore discharge amount that conventionally will strengthen pharmaceutical quantities or increasing mine tailing to low ash extract coal, production cost improves on the one hand, is on the other handGuarantee cleans ash, just will certainly cause tail coal ash content on the low side, cause cleaned coal to be lost in tail coal and cause the wave of coal resourcesTake, product line is also more single, and production technology is difficult for regulating. In order to solve the problem existing in above-mentioned actual production, proposeA kind of column-type floatation equipment. Flotation column has formed the trend that unidirectional ash content distributes on the whole along post height, from trapping districtBottom to selected district, in post, ash content and the sulphur content of ore pulp are continuous downward trend. The utility model passes through at floatation equipmentThe location in selected district and quantitatively shunting reach the object that regulates one section of cleans ash and improve the rate of recovery.
Summary of the invention
Goal of the invention: although the rotational flow microbubble flotation column using in coal separation mining processing industry at present can be obtained goodIndustrial index, but the ash adjust of single device head coal product mainly leans on the tune of regime of agent, pulp density, mine tailing discharge capacity etc.Joint method, concentrate overflow liquid level cannot regulate, and often can not control to adjust timely and effectively smart pit ash index in production.In actual production, to expect that low ash extract coal will strengthen the ore discharge amount of pharmaceutical quantities or increasing mine tailing conventionally, produces on the one handCost improves, and on the other hand in order to ensure cleans ash, just will certainly cause tail coal ash content on the low side, causes cleaned coal to be lost in tail coalAnd cause the waste of coal resources, and product line is also more single, and production technology is difficult for regulating. In order to solve in above-mentioned actual productionThe technical problem existing, has proposed a kind of column-type floatation equipment. Flotation column has formed a unidirectional ash content on the whole along post heightThe trend distributing,, from the bottom in trapping district to selected district, in post, ash content and the sulphur content of ore pulp are continuous downward trend. This realityReach and regulate one section of cleans ash and improve the rate of recovery by the location in the selected district of floatation equipment and quantitative shunting with novelObject. And two sections of head coal products both can have been sold also can return as product separately and mixed in head coal product, can maximum limitDegree ground meets user's different demands, has improved the economic benefit of enterprise.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of column-type floatation equipment, described floatation equipment is divided into scans district (eddy flow district) 2, trapping district 1 and selected district (foamDistrict) 22, mainly comprise two sections of overfalls 7, two sections of overflow launders 8, concentrate discharge gate II9, one section of overflow launder 11, concentrate discharge gate I12, mineral slurry flux meter I13, ash content on-line detecting system I14, mineral slurry flux meter II15, ash content on-line detecting system II16,Integrated control system 17, flow valve control device 18, two sections of overflow liquid level control valve devices 19, two sections of overflow Liquid level adjusting valvesDoor 20, two sections of spillway discharge control valves 21 etc., is characterized in that at the middle hypomere of the selected district of floatation equipment cylinder symmetrically4 overfalls that distributed, two sections of overflow launders 8 and one section of overflow launder 11 are arranged in middle hypomere and the epimere in selected district; Two sectionsOverfall is along being distributed as on height of column, a little higher than selected district of overfall least significant end floor level height, the going up most of overfallEnd is higher than selected district center level height certain distance, and the hypomere of overfall is provided with the valve of controlling water kick liquid level, and epimere is provided withThe valve of controlling water kick amount; The cylinder bucket wall of device valve part is hollow structure, valve arrangement in the middle level of bucket wall (as accompanying drawing2); The measurement regulation of valve can ensure that overfall can be sealed by valve completely, flow valve control device 18 and two sections of overflowsLiquid level valve control device 19 comprises signal of telecommunication receiving system, PLC Circuits System, drive unit, transmission device, valve seal portionPart; In the ash content that ash content on-line detecting system and mineral slurry flux meter obtain and data on flows set of signals, being transferred to integrated control isSystem 17, integrated control system 17 fills to flow valve control device 18 and two sections of overflow liquid level valve controls after data are processedPut the corresponding signal of telecommunication of 19 transmitting, regulate the height of two sections of overflow liquid level control valves 20 and two sections of spillway discharge control valves 21Degree, regulates two sections of overflow essence pit ash and productive rate with this, the final order that regulates one section of overflow essence pit ash and productive rate of realizing.
Two sections of overfalls 7 of the present utility model are by two sections of overflow liquid level control valves 20 and two sections of spillway discharge control valves 21While sealing completely, can be used as the common flotation column of two products and use.
In the time that two sections of overfalls 7 overflow high grey cleaned coal (with respect to one section of cleaned coal), one section of overflow launder 11 can obtainLow ash extract coal. In process of production, ash content on-line detecting system I14 and ash content on-line detecting system II16 detect monitoring in real timeOverflow cleans ash, and by ash content transfer of data to centralized control system 17. When one section of cleans ash is higher than the ash content settingWhen index, centralized control system 17 is to ash content on-line detecting system I14, ash content on-line detecting system II16, mineral slurry flux meter I13 and after the data analysis of mineral slurry flux meter II15 feedback processes, send corresponding electricity to flow valve control device 18Signal, the received rear drive of the signal of telecommunication and transmission device are started working, and control valve is pulled upwardly, and two sections of spillway discharges increase, and oneSection cleans ash touches the mark, and so far completes whole self-regulating process. And two sections of head coal products both can be separately as productSell and also can return and mix in head coal product, can meet to greatest extent user's different demands.
