Description
Technical field
The utility model relates to a kind of pan feeding ore pulp and carry out pretreated device before entering flotation device, belongs to the floatation equipment technical field.
Background technology
The coal preparation plant of China all is wet coal preparation more than 95%, and flotation device is wet coal preparation factory sorting granularity＜the most ripe effective screening installation of 0.5mm coal slime technology.Coal slime needs the pan feeding ore pulp is carried out preliminary treatment before entering flotation device, namely before coal slime enters flotation device, with ore pulp, medicament, the abundant disperse of air and mixing, reaches and reduces optionally purpose of floating agent consumption, raising sorting.Therefore the preliminary treatment of floatation feed is an important step of coal slime flotation.Up to now, domestic floatation feed pre-processing device has kaskad apparatus for pre-flotation pulp conditioning, ore pulp preprocessor, agitator, falls case etc.These existing equipment or function singlenesses, or complex structure, cost of manufacture are high, otherwise floor space large, increase civil engineering cost, can not be applicable to the various newly-built or coal preparation plants that transform fully.
The utility model content
Technical problem to be solved in the utility model provides a kind of floatation feed pretreatment unit, and this device medicament that can atomize ore pulp, medicament, air are fully mixed, and floor space is little.
The technical scheme that solves the problems of the technologies described above is:
A kind of floatation feed pre-processor unit, it is comprised of pan feeding chamber, mixing chamber, discharge chamber, nozzle, vertebral plate, atomizer, one side of pan feeding chamber is installed feeding pipe, and mixing chamber is connected to the below of pan feeding chamber, and discharge chamber is connected to the below of mixing chamber, the junction of pan feeding chamber and mixing chamber is the push pedal of sealing, a plurality of nozzles are installed in the push pedal, and the import of nozzle is indoor at pan feeding, and the spout of nozzle is in mixing chamber, atomizer is installed on the sidewall of mixing chamber, and discharging opening is arranged at the bottom of discharge chamber.
Above-mentioned floatation feed pre-processor unit, described push pedal are sphere, have a plurality of equally distributed circular holes at the push pedal sphere, and a plurality of nozzles are installed in respectively in the circular hole, and each nozzle tilts to the central axis of mixing chamber respectively.
Above-mentioned floatation feed pre-processor unit, described nozzle are conical nozzle, and the spout of nozzle is along the axis direction of nozzle, and the extended line of the axis of a plurality of nozzles intersects on the mixing chamber central axis.
The beneficial effects of the utility model are:
Floatation feed forms high-pressure spray through nozzle, and in mixing chamber, form negative pressure, air and floating agent enter mixing chamber through atomizer under suction function, through jet high-speed cutting, pulverizing, become bubble, floating agent to be atomized into trickle elaioleucite air dispersion, floatation feed, air, vaporific floating agent enter in mixing chamber and the discharge chamber and fully mix and diffusion, finish the preliminary treatment of ore pulp, enter the flotation device cell body by discharging opening again.The utility model has realized that the pre-mineralising of the front collection of wet coal preparation factory granularity＜0.50mm floatation feed flotation, floating agent atomizing and floatation feed, air evenly are mixed in the floatation feed preprocessing process of one, reach and improve the purpose that the floatation feed sorting is selective, reduce floatation clean coal ash content, raising clean coal yield, reduction floating agent consumption, has advantage simple in structure, that floor space is little, floating agent is atomized on one is effective, cost of manufacture is low, the coal preparation plant's adapted that is applicable to the newly-built of various scales and transforms.
