After all these years of mining, is the tailings pond in a hurry?
The design institute said filling!
The environmental protection department said filling!
Security said fill up!
The goaf also said to be filled, I am empty!!!
So, there is a contradiction? The piles of tailings have no long feet and cannot roll down by themselves. What equipment should be used to fill them?
Professional things to find a professional company, Yu Tai Heavy Industry to solve your problems!!!
Choose a professional tailings filling industrial pump, stable and reliable!
Where to charge, environmental protection, security, mine owners no longer have to worry about tailings.
Filling industrial pump and concrete drag pump belong to plunger pump, and filling industrial pump is developed on the basis of concrete pump in construction engineering. Its working principle is similar to that of ordinary drag pump. How to choose?
First of all, we need to find out our needs. Mine tailings filling has the following characteristics:
1The total filling volume is large, and the annual filling volume of a system is often up100000~200000m³；
22. Industrial filling pumps work continuously for a long time. Due to the unbalanced filling work, they are mostly used for filling as soon as possible. If necessary, they need to be24hours of uninterrupted work, even5~7Working continuously for days without interruption;
3High pumping pressure requirements,generally in5MPaAbove, the mine paste consistency is large, the viscosity is large, the conveying resistance is large, the conveying distance is long, and the conveying route is complex;
4The vulnerable parts of the pump, such as glasses plate, cutting ring, piston, delivery cylinder, etc., require good wear resistance, long service life, and easy maintenance and replacement.
5The use of filling equipment is stable, the failure rate is low, and the frequent failure of the equipment in the process of working will greatly increase the probability of pipe blockage.
6Suitable for conveying fine tailings slurrySPipe and cutting are more durable than ordinary concrete structures, and the service life is improved.5-8times, making maintenance costs cheaper.
Secondly, we will fill the industrial pump and ordinary drag pump comparison, which is better, at a glance!
1The annual delivery volume of ordinary towing pump is20000~30000m³ Left and right, average usage life3~5The annual volume of industrial filling pumps is in.100000~250000m³, average service life>5year;
2, ordinary drag pump generally continuous working time is not long, rarely in continuous24Hours of continuous work, industrial filling pump is designed to take into account this requirement;
3The concrete construction aggregate is mixed with its coarse aggregate, the large particle aggregate content ratio is high, the size is large, the viscosity is small, the cement dosage is large, the pipeline adhesion and flow resistance are small, the total transmission distance is short, the transmission route is relatively simple, and the pump pressure is generally not large. The industrial filling system of its aggregate ratio of coarse aggregate, large particle aggregate content ratio is low, the size is small, the amount of cement is small, the pipeline adhesion, flow resistance is large, the total transmission distance is short, the transmission route is complex, the pump pressure requirements are high.
4Because of its small cylinder diameter and short stroke, ordinary towing pump determines its high pumping commutation frequency, large impact vibration and fast equipment wear under the condition of the same lift and conveying volume, and its pump is not suitable for continuous long-term work. The industrial filling pump is designed to have a large cylinder diameter and a long stroke, which determines that it obtains a very low commutation frequency under the same lift and conveying volume conditions. Its operation is stable, the equipment wears slowly, and it is suitable for continuous long-term work.
51. There are many manufacturers of ordinary drag pumps, and the market competition is fierce. In order to reduce costs, manufacturers choose their accessories at different levels. Most of the control systems are electronic control systems, and the stability and reliability of their equipment are relatively low. In order to maintain their work stability and durability, their accessories are mostly international famous brands, and their control systems are mostly hydraulic control, with low failure rate.
Again, some special design instructions for industrial filling pumps for mine filling:
The whole filling industrial pump is designed according to the characteristics of continuous long time, stable and reliable work, long service life of the whole machine and small working impact.
In order to improve the fluidity of the slurry, the hopper adopts a non-accumulating material design, and the bottom steel plate is made of wear-resistant materials, which is suitable for working with large quantities;
For mine filling fine particle size slurry, designedSTube, cutting ring structure, stable performance, avoid hydraulic cutting effect, can solve the industry problem of long-distance and high-pressure transportation of fine-particle materials.
Conveying cylinder,SIn order to adapt to the characteristics of high pressure, the pipe distribution valve is designed to be thickened, and the inner wall of the conveying cylinder is treated with double chromium plating and large thickness technology to increase its wear resistance;
The conveying cylinder adopts large cylinder diameter and long stroke design. For large amount of work, it improves slurry suction, improves work efficiency, reduces its reversing frequency, and reduces wear rate;
The piston of the conveying cylinder is made of special wear-resistant materials to ensure its large amount, long-term continuous work and long service life;
SThe pipe distribution valve and cutting ring are processed and designed to adapt to the conveying conditions of fine slurry and paste and to adapt to long-term continuous work;
Change the key control system to the hydraulic control system. Its hydraulic oil pump, hydraulic valve, hydraulic pipeline, and hydraulic joints are all imported brands, and multiple filtering technology is adopted to maintain the stable and lasting work of the system and reduce the failure rate to adapt to long-term continuous Working conditions, low failure rate can greatly reduce the chance of pipe blockage.
Double lubrication system, and the use of international brand lubrication pump, for long-term continuous work parts by reliable lubrication, prolong the service life of seals, reduce the failure rate, adapt to long-term continuous work;
Increased automation control, humanized programming, and increase the fault automatic detection and processing technology, sensors using international brands;
Power and power control components are selected large-capacity components, and the use of international well-known brands to increase its reliability, low failure rate, long life and other advantages.
To sum up, Yutai Heavy Industry gives our suggestions:
Ordinary concrete drag pump can be used for mine filling, but its life is not long, the components are easy to wear, the work efficiency is not high, and can not achieve long-term continuous work, so it is not fully applicable to the requirements of mine industrial filling. The industrial filling pump is a professional equipment for mine industrial filling requirements, which fully meets the requirements of all aspects of industrial filling production.
