Multi-stage vibration screening equipment for coal gangue separation and method thereof

Abstract

The invention discloses multi-stage vibration screening equipment for coal gangue separation. The multi-stage vibration screening equipment comprises a multi-stage vibration screen and is characterized in that the multi-stage vibration screen comprises a supporting frame, damping columns are arranged at the four corners of the supporting frame, a vibration screen box is arranged on the damping columns jointly, a vibration screen box cover is arranged above the vibration screen box, and a feeding port is formed in the vibration screen box cover; a discharging box is arranged below the vibration screen box cover, a first discharging opening and a second discharging opening are formed in the lower portion of the discharging box, coal gangue conveying belts which are mutually distributed in a mirror image manner are arranged at one side of the multi-stage vibration screen, the first discharging opening and the second discharging opening are formed above the different coal gangue conveying belts respectively, and bagging mechanisms are arranged at the top ends of the coal gangue conveying belts; and a stacking mechanism is arranged at one side of each bagging mechanism. According to the multi-stage vibration screening equipment, coal gangue can be conveniently sorted, the coal gangue of different specifications can be recycled, the recycling efficiency of the coal gangue is improved, the coal gangue is directly bagged, the trouble of loading and transporting of the coal gangue is reduced, smoke dust is not prone to being generated in the loading and transporting process, and pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of coal mine separation, in particular to a multi-stage vibration screening device and method for coal gangue separation. Background technique [0002] Coal gangue is the waste slag produced during the mining process of coal. Among all the industrial solid fertilizer discharges in China, the discharge of such waste slag has remained high, and the discharge of a large amount of coal gangue has seriously occupied China's land resources. , has polluted a lot of woodland, which has a great impact on the ecological structure of China's land and has caused great damage to the ecological environment. Therefore, in order to improve the comprehensive utilization of coal gangue and maintain the sustainable development of mine resources, it is of great significance. At present , the utilization of coal gangue includes brick making, power generation, building blocks and other building materials, production of cement ins...

Problems solved by technology

[0002] Coal gangue is the waste slag produced during the mining process of coal. Among all the industrial solid fertilizer discharges in China, the discharge of such waste slag has remained high, and the discharge of a large amount of coal gangue has seriously occupied China's land resources. , has polluted a lot of woodland, which has a great impact on the ecological structure of China's land and has caused great damage to the ecological environment. Therefore, in order to improve the comprehensive utilization of coal gangue and maintain the sustainable development of mine resources, it is of great significance. At present , the utilization of coal gangue includes brick making, power generation, building blocks and other building materials, production of cement instead of clay, production of micron-scale porous ceramics, production of rubber reinforcing agents, production of mullite and cordierite, and coal gangue for concrete aggregates , backfilling mine goaf or paving materials, coal gangue gas production, coal gangue production of fertilizers, soil improvement, coal gangue extraction of chemical products, production of new industrial fillers (for foam artificial leather, film, rubber industrial products and coatings, etc.), Used as raw materials for pottery and refractory materials, reclamation and greening of coal gangue hills, and utilization of spontaneous combustion heat energy of coal gangue hills. The thickness and size of coal gangue are different, and the purposes of recycling are also different. In addition, coal gangue is prone to dust during transportation, so it is used directly When muck trucks transport coal gangue, it is easy to cause pollution to roads, etc. In view of this situation, a multi-stage vibrating screening equipment and method for sorting coal gangue are proposed
