技术领域Technical Field
本发明涉及矿物洗选加工技术领域，具体涉及一种浮选锥回收微细颗粒精煤装置。The invention relates to the technical field of mineral washing and processing, and in particular to a flotation cone device for recovering fine particle clean coal.
背景技术Background technique
目前，洗煤厂正在使用的煤泥水中回收微细颗粒精煤设备，为传统的机械搅拌式浮选机，以年产100万吨洗煤厂为例，浮选机自身配套的动力为183KW(浮选)+75KW(入料)+15KW(预处理)共273KW,动力大，生产成本高，导致较多洗煤厂放弃微细颗粒精煤的回收，浪费了宝贵资源。而配套了浮选机的洗煤厂的回收微细颗粒精煤的经济效益较低。浮选机要在地面4米以上或楼房安装，采用4台以上大功率电机一个方向同时旋转，有时会产生共振，形成巨大的共振力，所以要配套坚固的设备基础，设备基础设施投资大，建设周期长。At present, the equipment used by coal washing plants to recover fine particles of clean coal from coal sludge water is a traditional mechanical stirring flotation machine. Taking a coal washing plant with an annual output of 1 million tons as an example, the power of the flotation machine itself is 183KW (flotation) + 75KW (feeding) + 15KW (pretreatment), a total of 273KW. The power is large and the production cost is high, which leads to many coal washing plants giving up the recovery of fine particles of clean coal, wasting precious resources. The economic benefits of recovering fine particles of clean coal in coal washing plants equipped with flotation machines are relatively low. The flotation machine must be installed above 4 meters above the ground or in a building, and more than 4 high-power motors are used to rotate in one direction at the same time, which sometimes resonates and forms a huge resonant force, so a solid equipment foundation must be provided, and the equipment infrastructure investment is large and the construction period is long.
在煤泥水中回收微细颗粒精煤，目前在国内及国际上均采用浮选机回收精煤工艺，其原理为将煤泥水和浮选油(由浮选剂、起泡剂、捕收剂组成)充分混合而矿化，在浮选机转子旋转搅拌的同时利用负压吸入空气生成气泡，带有亲油特性的微细颗粒精煤吸附在气泡表面上浮到液面上，将带有精煤的气泡回收压滤提取合格成品精煤，无亲油性比重大的矸石、泥沙下沉聚集回收。To recover fine particles of clean coal from coal sludge water, the flotation machine is currently used both domestically and internationally to recover clean coal. The principle is to fully mix the coal sludge water and flotation oil (composed of flotation agent, frother and collector) to mineralize them. While the flotation machine rotor rotates and stirs, negative pressure is used to inhale air to generate bubbles. Fine particles of clean coal with lipophilic properties are adsorbed on the surface of the bubbles and float to the liquid surface. The bubbles carrying the clean coal are recovered and filtered to extract qualified finished clean coal. Gangue and sediment with high lipophilicity sink and gather for recovery.
目前，浮选锥回收微细颗粒精煤装置，经济效率比较底，生产成本高，设备造价比较高，操作复杂。At present, the flotation cone recovery of fine particle clean coal devices has relatively low economic efficiency, high production cost, high equipment cost and complex operation.

When the coal slurry water is being transported, the flotation oil regulating valve 22 is opened to allow the oil in the flotation oil tank 19 to flow into the flotation oil receiving hopper 17 through the oil outlet pipe 21, and then the oil is mixed with the peat water through the flotation oil injection pipe 16, and then the mixed liquid is transported to the inside of the mineralizer 6 through the flotation feed pipe 5, and then the coal slurry water is passed through the flotation oil pump 5. The slurry flows slowly down through the mineralizer 6 inner tube 606 outer wall of the mineralizer guide plate 603, then the roots blower 1 starts to work, open the air release valve 13 and the air supply auxiliary regulating valve 14 to allow the gas to be transported to the bubble generator 3 through the air supply pipeline 2, then the bubble generator 3 starts to work, and the mixed peat water is blown out of the bubble generator air chamber 302 through the bubble generator bubble breaking circular hole net 305, and the blown peat water will flow to the lowest point along the flotation cone 10, and the tail coal will be The water output variable frequency pump 11 starts to work, and the peat water of the water inlet bubble generator 3 is transported to the flotation bin assembly 8 through the tail coal water to coal slurry water concentrator pipeline 12 of the tail coal water output variable frequency pump 11. At this time, the flotation clean coal scraping motor 15 inside the flotation bin assembly 8 drives the central axis 30 of the bubble feeder to rotate through the fixed chassis 29 of the bubble feeder transmission system. At this time, the bubble feeder blade 31 located on the outer wall of the central axis 30 of the bubble feeder will rotate with it, and then The bubble feeder transmission sector gear 32 drives another group of bubble feeder central shafts 30 to rotate, so that the clean coal attached to the flotation bin assembly 8 can be scraped to the lowest point of the flotation bin assembly 8, and then the flotation clean coal filter press feed pump 26 and the flotation clean coal filter press pipeline 27 discharge the clean coal, which can greatly improve the economic efficiency and greatly reduce the production cost. In addition, the flotation cone recovery of fine particle clean coal equipment has a relatively low cost, and the operation is relatively simple and convenient to use.
