Abstract

The utility model relates to a novel changeable inflator type flotation column which is composed of a column body, a foam overflow funnel, an ore feeding pipe, an inflator, an ore tailing pipe, and a machine frame and is characterized in that the inflator which is formed by that inflators and spare inflators are arranged in the column body at intervals comprises a cloth bag, a bracket, an inflating pipe, the cloth bag is sheathed out of the bracket, and the inflating pipe is connected with the bracket through pipe joints. A transition chamber whose upper end is welded on a bottom plate on the lower part in the column body is sheathed out of the inflator, the upper end port of the transition chamber is provided with a movable cover is arranged, and the lower end port is provided with a flange cover. The lower end of the inflating pipe penetrates through the flange cover and is fixed by a stopping annular ring. The utility model with the advantages of simple structure, less investment and convenient operation can be replaced or maintained at will in the manufacture.

Description

Changeable aerator type flotation cell

The utility model relates to a kind of nothing and stirs air pressing type floatation equipment, a kind of novel interchangeable aerator flotation column of more specifically saying so.

In the production process of ore dressing, existing nothing stir micropore on the aerator flotation column in alkaline ore pulp very easily fouling block, therefore influence inflation effect needs often to change, but just can carry out behind the ore drawing slurry that must stop production when changing, thereby influence is produced.Once stirred ore pulp with agitation impeller flotator, but this device structure complexity, the big and power consumption of investment.

The purpose of this utility model provides a kind ofly can arbitrarily take out replacing or maintenance and simple in structure, easy to operate novel interchangeable aerator flotation column in process of production.

The purpose of this utility model is realized by following technical scheme.

The utility model is equipped with the foam overflow downcomer that its lower end has a concentrate pipe by cylindrical shell, cylindrical shell internal upper part, cylinder lateral wall is equipped with a mineral-feeding pipe, has a manhole, on the inner barrel base plate aerator is housed, debris tube is housed in the cylindrical shell bottom and frame is formed, and it is characterized in that:

A, described aerator comprise cloth bag, support, gas tube, and cloth bag is placed in outside the support, and gas tube is connected in support by pipe joint;

B, aerator overcoat one upper end are welded in the transition chamber on the lower raft in the cylindrical shell, and its upper port has a removable cover, and lower port is equipped with a blind flange, and it is fixing by stop garden ring that blind flange is passed in the gas tube lower end;

C, aerator are by being spaced in cylindrical shell with aerator and standby aerator.

The utility model has the advantages that because aerator can arbitrarily take out in transition chamber in upper and lower slip, and be divided into and be spaced, so under the situation that need not to stop production, can arbitrarily take out and change or keep in repair with aerator and standby aerator.

Another advantage of the present utility model is simple in structure, and small investment is easy to operate, is beneficial to and applies.

This utility model structural representation of Fig. 1,

Fig. 2 is the aerator structural representation of overcoat transition chamber.

By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.

(referring to Fig. 1,2) cylindrical shell 1 internal upper part is adorned the foam overflow downcomer 2 that its lower end has a concentrate pipe 3, and cylindrical shell 1 sidewall is equipped with a mineral-feeding pipe 4, has a manhole 5, and a debris tube 7 is adorned in cylindrical shell 1 bottom, and cylindrical shell places on the frame 8.Cloth bag 9 is placed in outside the support 10, a rubber piston 17 is pacified in gas tube 11 upper ends, be connected in support 10 by pipe joint 12 and constitute aerator 6, aerator 6 overcoats one upper end is welded in the transition chamber 13 on the lower raft in the cylindrical shell 1, port is adorned the removable cover 14 of a band torque spring thereon, lower port is adorned a blind flange 15, makes gas tube 11 lower ends pass blind flange 15, its outer peace one stop garden ring 16.Welding one is communicated with inflation short tube 18 1 ends of transition chamber 13 on the blind flange 15, and short tube 18 other ends connect total air valve.

In ore dressing is produced, gas tube 6 is divided into spaced at usefulness aerator 19 and standby aerator 20, at first open the total air valve that is communicated with at the short tube 18 of the transition chamber 13 of using aerator 19, compressed air enters transition chamber 13 through short tube 18, promote to move on the rubber piston 17,6 of aerators back down the removable cover 14 by torque spring control, by the stop garden ring 16 of aerator 6 afterbodys, move on blind flange 15 control pistons 17, make aerator 6 enter duty.If need to change or maintenance, open the total air valve of the short tube 18 that connects standby aerator 20 earlier, make standby aerator 20 enter the operating position, carry out work, close the total air valve that is connected at the short tube 18 of using aerator 19 again, the pressure of ore pulp pushes back transition chamber 13 back removable covers 17 with aerator 6 and closes automatically, pulls down blind flange 15 and can take out aerator 6.Thereby do not influence ordinary production.
