Description

Novel high-efficient flotation device

The technical field is as follows:

the utility model relates to a coal mine equipment technical field especially relates to a novel high-efficient flotation device.

Background art:

the flotation machine is the most key coal dressing equipment in the coal dressing industry, the flotation machine mixes the coal slurry with a flotation reagent, so that minerals are bonded on the foam, and the foam floats to the pulp surface to form mineralized foam for dressing; the existing mineralized foam is generally scraped by a mechanical foam scraper, but the mechanical foam scraper has poor foam scraping effect, is easy to cause great disturbance to the liquid level, is easy to damage the foam, has low flotation efficiency, is easy to break down when a mechanical structure is in a humid and severe working environment for a long time, and has short service life of equipment.

The utility model has the following contents:

an object of the utility model is to provide a novel high-efficient flotation device is put.

The content of the utility model is as follows: a novel efficient flotation machine comprises a vertically arranged flotation barrel, wherein a discharge port is formed in the bottom end of the flotation barrel, a feed port is formed in the side wall of the flotation barrel, a pedestrian bridge is arranged at the top end of the flotation barrel, a medicament tube is concentrically arranged in the flotation barrel and fixedly inserted into the pedestrian bridge, the novel efficient flotation machine further comprises a foam guide barrel, the foam guide barrel is concentrically and fixedly installed on the medicament tube, the foam guide barrel is conical, a plurality of medicament spray holes are uniformly distributed in the bottom end of the medicament tube along the circumferential direction and are positioned under the foam guide barrel, a collecting ring pipe is sleeved outside the flotation barrel and is positioned on the upper portion of the foam guide barrel in the height direction, a foam suction straight pipe is arranged on the collecting ring pipe and is communicated inwards, and the other end of the foam suction straight pipe is communicated with the inner cavity of the flotation barrel, the axis of the bubble suction straight pipe does not intersect with the axis of the flotation cylinder, the collecting ring pipe is connected with a bubble suction main pipe outwards along the tangential direction, and the bubble suction main pipe is communicated with a vacuum pump.

Furthermore, the taper of the foam guide cylinder is 30-45 degrees.

The utility model has the advantages that: the utility model discloses simple structure designs conical foam guide cylinder, can not only make the mineral foam that rises concentrate on around the foam guide cylinder, forms the annular foam layer that is close to flotation cylinder inner wall, plays the effect of liquid level stationary flow moreover, designs annular collection ring canal and is the suction bubble straight tube of vortex form simultaneously and discharges mineral foam, and it is efficient to collect mineral foam, and the mineral foam is damaged few, and flotation efficiency is high.

Description of the drawings:

FIG. 1 is a perspective view of the overall structure of the present invention;

fig. 2 is a top view of the present invention;

3 FIG. 3 3 3 is 3 a 3 cross 3- 3 sectional 3 view 3 taken 3 along 3 A 3- 3 A 3 of 3 FIG. 3 2 3; 3

In the figure, a flotation cylinder 1, a discharge port 2, a feed port 3, a pedestrian bridge 4, a medicament pipe 5, a foam guide cylinder 6, a medicament spray hole 7, a collecting ring pipe 8, a foam suction straight pipe 9, a foam suction main pipe 10 and a vacuum pump 11.

The specific implementation mode is as follows:

as shown in fig. 1 to 3, a novel efficient flotation machine comprises a vertically arranged flotation cylinder 1, a discharge port 2 is arranged at the bottom end of the flotation cylinder 1, a feed port 3 is arranged on the side wall of the flotation cylinder 1, a pedestrian bridge 4 is arranged at the top end of the flotation cylinder 1, a chemical tube 5 is concentrically arranged in the flotation cylinder 4, the chemical tube 5 is fixedly inserted on the pedestrian bridge 4, the novel efficient flotation machine further comprises a foam guide cylinder 6, the foam guide cylinder 6 is concentrically and fixedly installed on the chemical tube 5, the foam guide cylinder 6 is conical, a plurality of chemical spray holes 7 are uniformly distributed at the bottom end of the chemical tube 5 along the circumferential direction, the chemical spray holes 7 are positioned under the foam guide cylinder 6, a collecting ring pipe 8 is sleeved outside the flotation cylinder 1, and the collecting ring pipe 8 is positioned at the upper part of the foam guide cylinder 6 in the height direction, a bubble suction straight pipe 9 is arranged on the collecting ring pipe 8 and is communicated inwards, the other end of the bubble suction straight pipe 9 is communicated with the inner cavity of the flotation cylinder 1, the axis of the bubble suction straight pipe 9 is not intersected with the axis of the flotation cylinder 1, the collecting ring pipe 8 is connected with a bubble suction main pipe 10 outwards along the tangential direction, and the bubble suction main pipe 10 is communicated with a vacuum pump 11; the taper of the foam guide cylinder 6 is 30-45 degrees.

The working principle is as follows: during operation, coal slurry is input into the flotation cylinder 1 from the feed inlet 3, meanwhile, flotation agents enter from the agent pipe 5 and are finally sprayed out of the agent spray holes 7 into the flotation cylinder 1, flotation foams are finally gathered around the foam guide cylinder 6 to form an annular foam layer, and the vacuum pump 11 is started at regular time to discharge mineral foams through the foam suction straight pipe 9 and the collecting ring pipe 8.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
