Description

A kind of flotation column microvesicle generators

Technical field

The utility model belongs to mineral processing flotation column supply and makes bubble equipment technical field, is primarily related to a kind of flotation column micro- Bubble generator.

Background technology

At present, the microvesicle generators for using on mineral processing flotation column, are commonly called as foam maker or foam gun, drive internal fumarole The mechanism of the stopper motion of opening and closing, installed in afterbody, this mechanism common are air cylinder structure, membrane configuration, patent《One kind is floating Select post foam maker》(the patent No.：ZL201120267862.2) airbag structure of publicity etc..When being filled with compressed air to foam maker When, tail structure component axially-movable is promoted by air pressure, the internal stopper motion to control fumarole opening and closing is driven, beat Open fumarole and make bubble to flotation column jet.Conversely, closing compressed air source, subtract to the air pressure for driving above-mentioned tail structure Little or disappearance, under the effect of opposite side compression spring, drives the internal stopper counter motion to control fumarole opening and closing, will spray Pore is closed, and prevents ore pulp in flotation column from irrigating into foam maker.

Air cylinder structure needs clean air source, use environment typically cannot ensure；Membrane configuration and patent《A kind of flotation column foaming Device》(the patent No.：ZL201120267862.2) the airbag structure of publicity, principle is consistent, causes close by compressed air pressure change Envelope gas chamber volume change, two kinds of structures its essence is all rubber parts elastic deformation vertically, although source of the gas cleannes are required It is not tight, but when sealed air chamber's axial expansion, can receive its rubber Effect of Materials itself, air bag and external shell frictional force it is larger, Or diaphragm is larger with pinch seal pressing plate frictional force, connecting rod axially-movable underaction is promoted.Diaphragm type and air sac type structure, also Need to consider that material elastic parameter itself and compressed air pressure, flotation column ore pulp pressure, parameter of spring pressure etc. are matched, After barrier film and bag material are aging, elastic parameter will great changes will take place, so that the parameter of design structure is unbalance, causes drive There is exception in motivation structure, and foam maker fumarole is not opened or fitted badly.In a word, all there is certain skill in several structures of this common Art defect, it is impossible to control the on-off action of stopper at fumarole well.

Utility model content

For the technical problem that prior art is present, the purpose of this utility model is to provide a kind of microvesicle generators, solves The abnormal problem that drive mechanism easily occurs, so as to solve the most common failure that fumarole is not opened or fitted badly, makes foam maker Can be more stable, reliable.

To achieve these goals, the technical solution adopted in the utility model is：

A kind of foam generator for flotation columns of new construction, including shower nozzle, wear resistant spray nozzle, chock plug, connecting rod, body, compressed air hose Joint, end cap fittings body, air bag, bladder support set, spring, housing, clamping air bag thread bush, nut etc..It is internal for driving Air bag of stopper motion etc., in patent《A kind of foam generator for flotation columns》(the patent No.：ZL201120267862.2) publicity On the basis of technical pattern, make improvements, make balloon side towards sunken inside, exactly air bag bottom face is pressed into inside it, shape Into cavity, corresponding air bag lumen portion is changed into annular slot chamber, by patent《A kind of foam generator for flotation columns》(the patent No.： ZL201120267862.2) the sealing clamp of sequence number 10 of Figure of description, diameter reducing thickness increases, and stretching is improving rear gasbag Cavity in, referred to as bladder support set is played a supporting role to air bag；The airbag wall of above-mentioned patented technology no longer selects fold Structure, smooths regular, and airbag wall is attached to inner walls and bladder support and covers on outside cylinder wall, air bag in inner walls and Part between support set outside cylinder wall, forms annulus shape chamber.After microvesicle generators are installed to flotation column, compression is empty When gas or Spring driving connecting rod axially-movable, airbag wall is adjacent to wall and separates with wherein one, and radial motion is adjacent in another wall On.(just as two palms are clipped after inflated balloon flattens in balloon, rubbing is the same, balloon wall appropriate section and a palmar aspect It is initially separated, starts to fit with another palmar aspect, palm does not feel as the force of sliding friction between balloon wall and palmar aspect.) Compared with above-mentioned patented technology, this slides using new microvesicle generators airbag wall periphery is no longer relative with shell body, from And eliminate sliding friction problem between air bag and housing；With at present diaphragm structure compared with, eliminate between diaphragm and pressing plate Sliding friction problem.Due to eliminating above-mentioned frictional force, the utility model technology make the action of driving chock plug more flexibly, can Lean on, so that microvesicle generators function obtains basic assurance.The invention is less by bag material elasticity effect, and air chamber of the present invention holds Product change only has high requirement not against rubber parts elasticity itself to its pliability.Act on the air in annulus bottom of chamber face Pressure, affects on driving force, and in the timing of air pressure one, substantially definite value, without the need for considering material ageing problem, is opened or closed The spring pressure that fumarole stopper mechanism needs, more can accurately calculate determination, or will not change substantially after setting up, and the technology is implemented After microvesicle generators performance will be made more stable, reliable.For air bag 9, can be by size before reasonable material, rational assembling And shape, rational manufacturing process etc. ensure its performance.
