The utility model has four flotation troughs, the holding capacity of the single trough is 14.2 m+ 3, and the total processing capability of the single trough is from 40 to 56.8 t/h. The utility model has the characteristics of advanced technology, reasonable structure, stable and reliable operation, obvious energy saving, etc. The utility model is suitable for floatable coal slurry or coal slurry which is difficult to float, and the coal bed of the coal slurry is below 0.5 mm; the utility model can be used for coal washerys of new construction and expanded reconstruction with large processing capability one year, and can be suitably used as floatation equipment in metallurgical ore dressing system.
Description
The utility model belongs to the floatation equipment of mine ore dressing system, the floatation equipment of particularly a kind of Treatment of Washing coal works coal slurry.
The XJM-8 type flotation machine is China's first shallow trench mechanical agitation type large flotation machines of succeeding in developing in 1978, and pan feeding is the single flow feed-type, and this flotation device exists in actual use: 1, single groove volume is little; 2, inflation lack of homogeneity; Deficiencies such as 3, metal consumption is big are so can not satisfy the needs of China coal preparation plant development.
The XJQM-14 type flotation machine of installing and using in Aug. 1st ore deposit coal preparation plant of Zaozhuang Mining Administration in 1987 is first shallow/deep groove type large flotation machines of China.The assembling form is one group of a three-flute.Though it is big to have single groove volume, the inflation good uniformity, advantage such as actual power consumption is low, 1, cell body assembling three-flute one, so flotation time is short, clean coal yield is lower; 2, three-flute one, overall volume is big, makes, transports, installs, overhauls all inconvenient; 3, diffuser is four assemblings, brings difficulty for installation and maintenance.
The purpose of this utility model is to improve the tail coal ash content, reduces the flotation agent consumption, reduces power consumption and metal consumption, improves the disposal ability of complete machine, and reaches manufacturing, transportation, installation, overhauls purpose easily.
The utility model is achieved in that the flotation cell (1) of flotation device is at least four grooves, whole cell body segment design, diffuser (15) below the rabbling mechanism (3) is designed to two semicircles, back taper circulating barrel (22) is installed on diffuser (15), diffuser (15) and back taper circulating barrel (22) also have impeller (13) bottom.Vertical box-shaped rack (5) is arranged above the cell body, divide two sections compositions, air shut-off valve (19) is arranged in the side of box-shaped rack (5).
The power transmission shaft (11) of rabbling mechanism (3) adopts the equal diameter circular shaft, and it is convenient to adjust axial location like this, and processing is simple, and interchangeability is strong.For equal diameter circular shaft vertical fixing is gone up in place, upper and lower end at bearing housing (24) respectively is equipped with wide inner ring ball bearing (25), the locking of this bearing (25) and power transmission shaft (11) utilizes Camlock cover (23) to realize, the thrust that produces by means of eccentric swing offset prevents axial float.
The transmission device of rabbling mechanism (3) adopts narrow V-type V-Belt Drive, and this transmission device is made up of large and small bead apex wheel and narrow V-type bead apex.
For avoiding the motor overload operation, the gear motor of float skimming device (4) and scrape between the bubble axle and adopt limit to turn round shaft coupling adopts sealed bearing and scrape the bubble shaft stool, so flexible movements, saves power.
Stabilier (16) all is equipped with at four jiaos of places, bottom at each flotation cell (1), and its effect is further control upwelling stable, and upwelling is play the guiding role; Antifriction plate (14) in each flotation cell (1) base plate inboard is to prevent the friction of high speed coal slurry stream to base plate, reinforcing soleplate.
The coal slurry that adjusted is good is entered by feed box (2), direct current mouth through feed box enters flotation cell (1), low-pressure air is pressed in the box-shaped rack (5) by air blast, enters hollow pipe (17) by air shut-off valve (19), imports the centre of impeller (13).Power transmission shaft (11) and impeller (13) rotation under drive unit drives make the low-pressure air that enters mix with coal slurry.Low-pressure air and coal slurry mixture impinge upon on the blade of diffuser (15) under the blade of impeller (13) drives, and air and coal slurry are further mixed, and the gassiness coal slurry is upwards spread from bottom land through diffuser (15), form stable upwelling.The bubble of mineralising rises to froth zone, the foam cleaned coal is scraped the bubble paddle and is scraped and enter cleaned coal chute (12), back taper circulating barrel (22) flotation again that the coal slurry of end mineralising enters next groove again through the direct current mouth enters nesting box (10) by the coal slurry after the groove sorting and discharges.
This cyclic process is ongoing along back taper circulating barrel (22), therefore is called " three-dimensional circulation ".Diffuser (15) and impeller (13) are wanted strict control from the distance of bottom land, to increase the stirring capacity of bottom land, improve the speed of upwelling, guarantee that Coarse Coal effectively suspends, thereby effectively avoid the precipitation of Coarse Coal in flotation cell (1).
The utility model has been owing to realized the flotation mode repeatedly of multiple-grooved, " three-dimensional circulation ", so flotation effect is good, and tail coal ash content height, the disposal ability of complete machine is big, under the same treatment ability, reduced metal consumption.This flotation machine impeller (13) diameter is big, rotating speed is low, low-pressure air adopts inflatable, add that the float skimming device driving mechanism adopts gear motor to add the bearing sealed bearing and limit is turned round shaft coupling, therefore power savings is remarkable, complete machine is designed to two sections, brings convenience for manufacturing, transportation, installation.
