Description
Technical Field
The invention relates to the technical field of ore dressing, in particular to a copper-sulfur ore dressing system with an improved foam pump installation mode.
Background
The ore pulp in the mineral processing industry often has foam to produce, and ordinary sediment stuff pump can not carry this kind of ore pulp that has foam, and the foam pump because possess special structure, can be used for carrying the foam that appears in mineral processing industry such as flotation well.
In the current large-scale concentrating mill, the froth ore pulp generated by the flotation machine is generally distributed intensively through a material separating gate valve, and then is conveyed to the next-stage flotation equipment by a vertical froth pump or recycled back to the previous-stage flotation equipment for treatment. For example, the copper-sulfur ore dressing system with the yield of 7000 tons/day originally designed by the applicant comprises a copper ore flotation system and a sulfur ore flotation system, and the copper ore flotation system and the sulfur ore flotation system both adopt a rough two-sweep step-by-step return process flow, which comprises the steps of rough dressing, first scavenging, second scavenging and carefully selecting, namely: after the ore is subjected to flotation by a roughing flotation machine, the generated foam ore pulp is conveyed to a concentration device for treatment, and the obtained tailings enter a scavenging flotation machine for flotation; the froth ore pulp generated by the scavenging primary flotation machine returns to the roughing flotation machine for treatment, and the obtained tailings enter the scavenging secondary flotation machine for flotation; the froth ore pulp generated by the scavenging second flotation machine is returned to the scavenging first flotation machine for treatment, and the obtained tailings go to a tailings pond or enter the next flotation system.
However, after the copper sulfur beneficiation system was put into trial production, the following problems were found:
1) The phenomenon of running out and dripping is serious. The vertical foam pump has small material box volume, which is only 0.3m 3, which is one tenth of the instantaneous flow of an actual pipeline, the foam elimination time is far insufficient, serious leakage and dripping phenomenon easily occurs, when the foam steam content is large, if the foam is not timely defoamed, the pumping efficiency is affected, the operation amount of flotation is affected, so that the water or the defoaming agent is needed to be manually and timely added into the material box for defoaming, and the operation is often deteriorated due to the unsuitable adding amount, and further malignant circulation is caused. In addition, the workbin is square, and the condition that the accumulated sand can not be discharged easily appears in inside, causes ore loss to influence the operating condition of pump.
2) It is difficult to maintain smooth operation of the pump. The vertical foam pump is difficult to be large-sized, a plurality of vertical foam pumps are required to be connected in parallel and are provided with a distributing gate valve, but the fault rate of the distributing gate valve is very high, the shutdown is often caused, and sometimes uneven distribution can cause that pumps with more ore pulp are not pumped, the pumps with less ore pulp are pumped, and the stable operation of the pumps is threatened.
3) The production loss caused by abnormal fluctuation of indexes is large, and the risk resistance of the system is poor. When the production encounters fluctuation, the ore pulp in the foam pump is washed outwards, so that the ore pulp is lost, the bearing under the pump body is blocked and burnt, and the fault rate of the foam pump is high. The vertical foam pump is used in parallel, one foam pump is stopped by fault, so that the operation of other pumps is changed, the pipeline designed by the original factory according to a process flow of one thick two-sweep gradual return is fixed, the fluctuation resistance and the risk resistance of the system are poor, the whole system is greatly influenced by the fault of the foam pump, the production parking accident is caused, the damage of the parking accident to equipment is large, and a large amount of ore pulp is lost.
4) The maximum clear water flow rate of the vertical foam pump is about 400m 3/h, when the ore selecting system is tried to run according to 60% load, the conveying capacity of the vertical foam pump is obviously insufficient, the distance design processing capacity is quite different, the full-load running cannot be coped with, and the yield requirement of 7000 tons/day cannot be met.
Therefore, there is a need for an improved mounting of foam pumps in beneficiation systems to ensure that the beneficiation systems can operate smoothly under normal loads.

Therefore, the foam ore pulp transportation is realized by the aid of natural height differences among the overflow pipes by optimally designing the installation mode of the foam pump in the foam conveying unit and additionally arranging the overflow pipes or the accident pipes, so that the copper-sulfur ore dressing system can also run down when the foam pump fails, and the occurrence of the parking accident is avoided.
Besides the faults, the open-close state of each overflow pipe or accident pipe can be adaptively adjusted according to the node where the foam pump which is actually faulty is located, so that the copper-sulfur ore dressing system always operates stably.
In addition, according to actual production requirements such as the change of the composition of raw ores and the fluctuation of production indexes, the open-close state of each foam pump and the open-close state of each overflow pipe can be adjusted, so that the flexible change of the process flow is realized, for example, the process flow can be changed into a coarse two-sweep gradual return, a three-switch copper selection and a full-open sulfur selection, or a half-open half-closed half-sequential return and the like.

2) Manual defoaming is avoided; according to the invention, the feeding pipe and the discharging pipe of the defoaming barrel are tangentially arranged, so that foam ore pulp enters the defoaming barrel tangentially and then enters the foam pump tangentially from the defoaming barrel, rotational flow is formed in the defoaming barrel, sand accumulation in the barrel can be reduced, a defoaming effect is achieved, in addition, a sealing cover is arranged above the defoaming barrel and a chimney is arranged, positive pressure pulp suction can be maintained, and the defoamed gas can be discharged in time, so that cavitation of the pump is reduced.

4) Failure-free; the foam pump runs stably without running and leaking, so that the probability of the foam pump to fail is reduced, and the foam pump does not need to be used in parallel, so that fluctuation of production indexes caused by the failure of a single foam pump is greatly weakened.
