Abstract

The utility model discloses a foam generator for mineral separation flotation columns. The novel structure of the foam generator utilizes an air bag to replace a piston portion of an air cylinder of a conventional foam generator in common structure, thereby solving the problems of back flowing of ore pulp and insufficiency of air supply caused by the facts that air sources are unclean and the piston of the air cylinder is easy to be blocked and halted due to detained sands, and achieving the purposes that the foam generator is insensitive to pollution of air sources and reliable to run. The air bag (9) of the novel foam generator is arranged between an end cap connector (7) and an inner spring (11) of a casing (12), a round hole is arranged at the center of the bottom of the air bag, and an air bag clamping screw pipe (15), a connecting rod (4) (fixedly connected with the air bag clamping screw pipe), a sealing press plate (10) and a nut (13) and the like are fixedly enclosed in the air bag. When high-pressure air is injected, the air bag is axially expanded and contracted, spraying holes are opened or closed correspondingly, and air supply or cut-off of the flotation columns is achieved.

Description

A kind of flotation column foam maker

Technical field

The utility model belongs to ore dressing flotation column air feed equipment technical field, and what relate generally to is a kind of flotation column foam maker.

Background technology

At present; The foam maker that on the ore dressing flotation column, uses; Its afterbody uses common air cylinder structure; Foam maker inside is connected with the piston rod of afterbody cylinder through screw thread in order to the stopper rod that stops up fumarole, and cylinder head is connected with the foam maker body of rod through screw thread, and the compressed air that promotes the motion of afterbody cylinder piston then directly is connected with anterior foam maker body of rod inner chamber through plastic tube.The problem that this structure exists is: gas source pipe advances slurry and pollutes; The unpurified gas of the band grains of sand directly gets into cylinder and makes cylinder malfunctioning (it is stuck to be detained sand between cylinder piston and casing wall); Cause the interior stopper of foam maker can't normally block or open fumarole; To such an extent as to ore pulp pours in down a chimney into foam maker in the flotation column, ore pulp refluxes in compressed air piping and precipitates blocking pipe; Or the fumarole of not opening can't be jet.Generally speaking, pipeline advances slurry, pollutes the compressed air phenomenon and is difficult to avoid, and for example works as a certain foam maker owing to excessive wear, and stopper can not stop ore pulp to pour in down a chimney fully when source of the gas is closed or shut down, and the foam maker of prior art can't adapt to above-mentioned environmental condition.

Summary of the invention

The purpose of the utility model is to propose a kind of flotation column foam maker, and the foam maker cylinder piston adopts air bag to replace, and effectively solves common foam maker cylinder piston and is prone to stuck being failure to actuate, and what cause pours in down a chimney problems such as ore pulp, air feed deficiency.Reach insensitive, the purpose of reliable motion to the pollution of source of the gas.

The utility model realizes that the technical scheme that above-mentioned purpose is taked is: a kind of flotation column foam maker comprises shower nozzle, wear-resisting nozzle, chock plug, connecting rod, body, compressed air pipe joint, end cap fittings body, spring, housing; In said housing, be provided with air bag; Air bag is between end cap fittings body and housing inner spring; The bottom centermost of air bag has a circular hole, and the clamping air bag screwed pipe that is used to clamp air bag is a sleeve structure, is connected with described connecting rod socket; Lobed dish type plane is used to compress air bag on the excircle of sleeve pipe, and the circular hole that the air bag bottom is passed at the rear portion of clamping air bag screwed pipe compresses sealing by sealing clamp.

The utility model is because the parts of foam maker promotion chock plug motion no longer are cylinder pistons, but by the air bag replacement, air bag radially is limited in the housing, but axial expansion or contraction drive the foam maker inner plug body and move, thereby open or close fumarole.Air bag is to the fricton-tight sealing surface of compressed-air actuated sealing; Pollution to source of the gas is insensitive; Reliable motion is prone to stuck being failure to actuate thereby solve the foam maker cylinder piston, and the fumarole that can't seal that causes pours in down a chimney ore pulp, foam maker only gas and or problem such as narrow-minded excessively.

The specific embodiment

In conjunction with accompanying drawing, the embodiment that provides the utility model is following.

As shown in Figure 1: a kind of flotation column foam maker comprises shower nozzle 1, wear-resisting nozzle 2, chock plug 3, connecting rod 4, body 5, compressed air pipe joint 6, end cap fittings body 7, air bag 9, sealing clamp 10, spring 11, housing 12 and clamps air bag screwed pipe 15; Wear-resisting nozzle 2 is installed in the shower nozzle 1; Shower nozzle 1 is connected with the threaded one end of body 5; The other end of body 5 is fixedly connected with end cap fittings body 7; Be communicated with compressed air pipe joint 6 on the end cap fittings body 7, housing 12 is connected with end cap fittings body 7 through screw 8, in housing 12, is provided with air bag 9, sealing clamp 10, spring 11 and clamps air bag screwed pipe 15.Connecting rod 4 is positioned at body 5 and is fixedly connected with chock plug 3 with housing 12, one ends, can close fumarole when chock plug 3 compresses with wear-resisting nozzle 2 inner conical surfaces, can open fumarole when leaving, and the other end of connecting rod 4 passes housing 12 and stretches out outside the housing 12.Air bag 9 is a cirque structure; Preferably be similar to the peviform structure, tub wall has ring-type fold, and purpose is not fragile when expanding; The bottom centermost of air bag (like diagram right-hand member center) has a circular hole; Hole size is suitable with clamping air bag screwed pipe 15 diameters of thread, and the flange of air bag 9 front portions (like the diagram left end) compresses the two fixing seal through screw 8 between end cap fittings body 7 and housing 12.Clamping air bag screwed pipe 15 is sleeve structure; Be connected with welded seal after connecting rod 4 sockets; On external cylindrical surface, has protruding dish type plane; Be used to compress air bag 9, the circular hole of air bag 9 bottoms is passed at the rear portion (diagram right-hand member) that clamps air bag screwed pipe 15, compresses the back forms sealing at air bag 9 inner chambers air chamber by sealing clamp 10, floor clip 14, nut 13.Spring 11 is installed in the housing 12, and right-hand member holds out against at housing 12 inner bottom surfaces, and left end holds out against on sealing clamp 10.Damage air bag 9 in order to prevent connecting rod 4 from rotating; Front portion (diagram left end portion) Cross section Design that clamps air bag screwed pipe 15 is non-round structure; Be inserted in antitorque 16; Be screwed for antitorque 16 on end cap fittings body 7, it and 15 of clamping air bag screwed pipes are the rotatable matched in clearance of sliding, and are used to prevent that connecting rod from rotating the destruction to air bag.Antitorque 16 with end cap fittings body 7 can be designed to one, also separable setting.

Like diagram, the operation principle of the utility model is: when compressed air pipe joint 6 is connected compressed air, compressed air through antitorque 16 with clamp in the air chamber that 15 slits entering of air bag screwed pipe are made up of end cap fittings body 7 air bags 9; Under the compressed air effect; The air bag axial expansion overcomes spring 11 force clamping air bag screwed pipe 15 and moves right, and opens shower nozzle 1 pore thereby drivening rod 4 and chock plug 3 move; Compressed air just enters into flotation column, accomplishes the air inlet action; When closing that flotation column (close gas quit work) or accidental cause cause that origin pressure descends or when not having pressure; The air chamber internal pressure descends; Spring 11 promotes sealing clamp 10 clamping air bag screwed pipes 15 and is moved to the left; Drivening rod 4 chock plugs 3 move, thereby sealing shower nozzle 1 pore can stop the interior ore pulp of flotation column to pour in down a chimney to foam gun and gas path pipe.
