Description

The novel mechanical agitation type flotation machine

Technical field

The utility model relates to a kind of flotation machinery, specifically, has related to a kind of novel mechanical agitation type flotation machine.

Background technology

Self-priming agitation impeller flotator in use; Find that there is following problem in it: because the floatation feed amount is greater than the design theory value; When the system band coal 500t/h left and right sides, to open 2 flotation devices and do not reached processing requirements, the situation of overflow will appear in flotation device.The A of first flotation device, the overflow of B chamber flow into the blanking pipeline that diameter is 400mm from A, B chamber overflow pipe, flow into the flotation concentrate pond then; Second, third flotation device then is that the overflow pipe of A chamber of A chamber and the 3rd flotation device of second flotation device connects together; The overflow pipe of the B chamber of second flotation device and the B chamber of the 3rd flotation device connects together, and so latter two overflow pipe is connected into the blanking pipeline inflow flotation concentrate pond of a 400mm; Because the overflow pipe diameter of the every chamber of flotation device is 700mm; First flotation device overflow discharging is actual to be the pipeline of the 400mm of pipeline entering of 2 700mm, and second flotation device and the 3rd flotation device overflow discharging then are the pipelines that the pipeline of 4 700mm gets into a 400mm, design unreasonable; In case the flotation device feeding increases; Flotation concentrate just is difficult to whole discharges, causes a large amount of flotation concentrates to emerge, and causes damp production.Because flotation device overflow discharging is untimely, liquid level is fluctuated, and the floating agent addition is difficult to regulate, and the floatation clean coal quality is difficult to guarantee; Ash content reaches about 9% when low, and mine tailing runs coal in a large number, and clean coal yield reduces; Reach 16% when ash content is high, the floatation clean coal ash content exceeds standard, and badly influences the benefit of enterprise.

In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.

Summary of the invention

The purpose of the utility model is the deficiency to prior art, thereby providing a kind of is easy to transform, cost is low, practical, novel mechanical agitation type flotation machine that reliability is high.

To achieve these goals; The technical scheme that the utility model adopted is: a kind of novel mechanical agitation type flotation machine; It includes the first flotation device A chamber and B chamber, the second flotation device A chamber and B chamber, the 3rd flotation device A chamber and B chamber, first tremie pipe, second tremie pipe, first Buffer Pool, second Buffer Pool and flotation concentrate pond; Wherein, The A chamber of first flotation device is connected said first tremie pipe through one first overflow pipe respectively with the B chamber; The A chamber of second flotation device links to each other through second overflow pipe with the A chamber of the 3rd flotation device, and the B chamber of second flotation device links to each other through the 3rd overflow pipe with the B chamber of the 3rd flotation device, and said second overflow pipe is connected said second tremie pipe respectively with said the 3rd overflow pipe; Said first tremie pipe and said second tremie pipe are communicated with said first Buffer Pool and said second Buffer Pool respectively, and said first Buffer Pool and said second Buffer Pool are communicated with said flotation concentrate pond respectively.

Based on above-mentioned, the interior diameter of said first tremie pipe is identical with the interior diameter of said first overflow pipe, and the interior diameter of said second tremie pipe is identical with the interior diameter of the interior diameter of said second overflow pipe, said the 3rd overflow pipe.

The relative prior art of the utility model has substantive distinguishing features and progress; Specifically, this novel mechanical agitation type flotation machine has solved the problem of flotation device overflow through the transformation to flotation device overflow drain tube road; And increased the treating capacity of flotation device; Guarantee quality of cleaned coal, realized continuous production, increased economic benefit.

Description of drawings

Fig. 1 is the side partial structurtes sketch map of the utility model.

The specific embodiment

Through the specific embodiment, the technical scheme of the utility model is done further detailed description below.

Through analyzing, find that the subject matter of existing flotation device is in the design of overflow tapping equipment, i.e. pipeline preparation is unreasonable, is the main cause of flotation device overflow; Through after the repeated measurement, find that there is the problem that workload is big, difficulty of construction is big in simple replacing pipeline, main pipeline is only changed in decision, sets up Buffer Pool then, and concentrate is entered earlier in the Buffer Pool, flows in the flotation concentrate pond through the feed opening at the bottom of the pond then; When accomplishing requirement, reduce workload to greatest extent.

As shown in Figure 1; A kind of novel mechanical agitation type flotation machine, it includes the first flotation device A chamber 3 and B chamber, the second flotation device A chamber 1 and B chamber, the 3rd flotation device A chamber 2 and B chamber, first tremie pipe 33, second tremie pipe 13, first Buffer Pool 34, second Buffer Pool 14 and flotation concentrate pond;

Wherein, The A chamber 3 of first flotation device is connected said first tremie pipe 33 through one first overflow pipe 32 respectively with the B chamber; The A chamber 1 of second flotation device links to each other through second overflow pipe 12 with the A chamber 2 of the 3rd flotation device; The B chamber of second flotation device links to each other through the 3rd overflow pipe with the B chamber of the 3rd flotation device; Said second overflow pipe 12 is connected said second tremie pipe 13 respectively with said the 3rd overflow pipe; Said first tremie pipe 33 is communicated with said first Buffer Pool 34 and said second Buffer Pool 14 respectively with said second tremie pipe 13, and said first Buffer Pool 34 is respectively arranged with feed opening 35 and feed opening 15 with said second Buffer Pool 14 bottoms, and said first Buffer Pool 34 is communicated with said flotation concentrate pond respectively with said second Buffer Pool 14.

The interior diameter of said first tremie pipe 33 is identical with the interior diameter of said first overflow pipe 32, and the interior diameter of said second tremie pipe 13 is identical with the interior diameter of the interior diameter of said second overflow pipe 12, said the 3rd overflow pipe.

Through transforming, the flotation device overflow can in time be discharged, and has solved the problem of flotation device overflow, and production can be carried out continuously; After transforming completion, the flotation device treating capacity is increased to about 500m3/h by original 398.66m3/h, and the efficiency of separation remains unchanged; After flotation device overflow discharging is unimpeded, level stability in the flotation device, floating agent addition stable and controllable, flotation concentrate ash content qualification rate is high, and ash content is between 10.5%-11.5%, and clean coal yield reaches 85%-90%, and fluctuation is little; Through transformation to flotation device, increased the treating capacity of flotation device, the floating agent addition is simple and easy to transfer, and floatation clean coal constant product quality, productive rate height have been realized continuous production, have increased economic benefit of enterprises.

Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Although with reference to preferred embodiment the utility model has been carried out detailed explanation, the those of ordinary skill in affiliated field is to be understood that: still can make amendment to the specific embodiment of the utility model perhaps is equal to replacement to the part technical characterictic; And not breaking away from the spirit of the utility model technical scheme, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
