Background technique

my country's tailings discharge is very large, and mining companies produce more than 1 billion tons of tailings every year, and the current stockpiled tailings have reached 8.051 billion tons. However, the comprehensive utilization rate of tailings in China is only about 8%, and a large number of tailings can only be piled in tailings ponds. However, there are more than 10,000 tailings ponds in China, and the total area of tailings ponds has reached 37282km ² . The existence of a large number of tailing ponds has brought a series of problems, including potential safety hazards, environmental pollution, large land occupation, and high operating costs. Not only that, many places in my country have clearly proposed the policy of not allowing new tailing ponds, which makes a large number of mines face the dilemma of having nowhere to discharge tailings. Therefore, the method of using traditional tailings ponds to deal with tailings is no longer suitable for the treatment requirements of tailings in my country, and effective methods must be adopted to deal with the discharge of tailings.

Tailings dry discharge technology is a new tailings treatment technology that has gradually emerged at home and abroad in recent years. It can not only greatly reduce the amount of tailings transported, improve the utilization rate of tailings backwater, reduce the occurrence of safety accidents such as tailings dam breaks, and prolong the The service life of tailings ponds or tailings dams can be reduced, the operating costs of tailings ponds or dams can be reduced, and mines that do not have the conditions for building tailings ponds can be developed, which has broad application prospects, economic and social benefits.

Since the beginning of the 21st century, with the development of high-frequency screening technology for ore dressing, people have gradually applied this technology to tailings treatment, making it have the function of tailings dehydration, thus solving the problem of tailings dehydration in dressing plants. The new topic of dry stacking supplements and perfects the concept of tailings disposal.

The new technology of tailings dehydration and dry discharge is a new technology that dehydrates the tailings, and the dry tailings can be directly dry-stacked, landfilled or shipped out. After using this technology, mineral processing enterprises will no longer need to build large thickeners, tailings dams, tailings long-distance transmission pipelines and tailings dam backwater long-distance transmission pipelines, saving valuable construction sites and a lot of infrastructure costs for enterprises. It avoids the major problems of damaging the ecological environment and potential safety hazards during the operation of the tailings pond, increases the utilization rate of backwater from about 70% to 75% to more than 95%, and realizes zero drainage in production, with huge social and economic benefits.

When water flows into the inner shell 28 (inner shell screen 50) of the secondary dehydration device, under the rotation of the disc 25, the large cone 27, the medium cone 29, the small cone 30 and the tailings discharge spiral blade 31, The water flow is thrown to the inner casing 28 (screen) of the secondary dehydration device, and the inner casing 28 (screen mesh) of the secondary dehydration device is cleaned. When water flows into the screen 39 of the third-stage dewatering device from the ore outlet 49 of the secondary dehydration device and the tailings discharge chute 37, under the action of the vibrator 40, the water passing through the screen 39 of the third-stage dehydration device also goes up and down continuously. Vibrate to clean the screen 39 of the three-stage dehydration device.

(7) After cleaning, turn off the main motor 16, the auxiliary motor 45 and the vibration exciter 40, lower the piston 11 of the lifting device, and put the bottom plate 12 flat.

The beneficial effects of the present invention are:

(1) The tailings are dehydrated through this equipment, so as to achieve the effect of tailings dry discharge, which can not only greatly reduce the amount of tailings transported, but also improve the utilization rate of backwater of tailings, and reduce the utilization rate of backwater from the original 70%~ From around 75% to over 95%.

(2) Tailings dry discharge can reduce the occurrence of safety accidents such as tailings dam failure, extend the service life of tailings ponds or tailings dams, reduce the operating costs of tailings ponds or dams, and can also develop The mines with tailings pool conditions have broad application prospects, economic and social benefits.

(3) The equipment has the function of tailings dehydration, which solves the problem of dehydration and dry stacking of tailings in the concentrator.

(4) Dewater the tailings, and the dry tailings can be directly dry-stacked, landfilled or shipped out. After the tailings are dehydrated, the mineral processing enterprises will not build large thickeners, tailings dams, tailings long-distance transmission pipelines and tailings dam backwater long-distance transmission pipelines, saving valuable construction sites and a lot of infrastructure costs for enterprises, social and economic The benefits are huge.
