Abstract
The utility model relates to a bubblefroth pushing device of a flotation machine. The bubblefroth pushing device is characterized in that the structure of the device comprises a cone-shaped bubblefroth pushing body, an annular spray pipe and a spray water inlet pipe; wherein, the cone-shaped bubble pushing bodywhich is a sealed cavity with an inverted frustum shape; an the annular spray pipe, which adopts is an annular pipe with an identical diameter which is identical to the upper frustum surface of the cone-shaped bubblefroth pushing body, and on which a water spray nozzle is arranged on the annular pipe; a the spray water inlet pipe, which adopts is a way pipe with the water inlet end vertically connected with the annular spray pipe. The bubblefroth pushing device of the flotation machine effectively prolongs the adsorption of the froth to the valuable metal, to ensure the bubblefroth to be continuously enriched upward along the inclined plane of the cone, and ensure the finished ore froth to be stably pushed into an outer annular bubblefroth groove, and finally the finished ore bubblefroth is wholly pushed into a finished ore discharging opening through a spray pipe water column, and thereby the purposes that the separation process is balanced, the finished ore bubblefroth output amount is stabilized, and the finished ore separation index is enhanced are achieved.
Description
Technical field
The utility model relates to a kind of foam pushing device of flotation device.
Background technology
Since 20th century, various floatation equipments continue to bring out, and the stability when floatation equipment sorts is the focus that everybody pays close attention to always, also are that everybody constantly studies, and fall over each other an importance of improving and improving.
Present floatation equipment is on control concentrate foam output, and the form of taking mainly contains two kinds:
A kind of is to take on thin axle blade to be installed, and drives its rotation with small machine, and the concentrate foam is scraped into foam tank.This kind device helps foam instant discharge smoothly to a certain extent, but under the big situation of foam output, easily will not scrape into foam tank in the lump through lower floor's foam of complete enrichment, does not improve the effect that sorts grade thereby have.
Another kind is to take nature to discharge method, and promptly the concentrate foam by follow-up generation constantly ejects the foam of the superiors, enters foam tank at last.This kind form is because the concentrate foam volume of upper end is big, and the foam of lower floor makes the valuable metal generation of foam absorption itself come off owing to the gravity that bears the upper foam generation can not get instant discharge easily, reduces the grade that sorts of concentrate.
The foam of two kinds of above-mentioned principal modes is discharged mode and is all had the limitation of himself, and mineral to sort be need be to the greatest extent how to reclaim valuable metal from mineral, so improve concentrate grade and the rate of recovery is an important breach.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provides a kind of and can effectively control concentrate foam discharge process, stable foam output, promotes the foam pushing device of foam to the flotation device of the final concentrate sorting index of enrichment, the raising of concentrate.
The purpose of this utility model is achieved through the following technical solutions.
A kind of foam pushing device of flotation device is characterized in that the structure of this device comprises:
Taper pushes away that foam-this pushes away the seal chamber that foam is an inverted taper type structure;
Annular spray pipe-this sparge pipe has hole for water spraying for to push away the isometrical ring pipe in foam epicone table top limit with taper on ring pipe;
Shower water water inlet pipe-this water inlet pipe is that a water inlet end vertically is connected in the siphunculus on the annular spray pipe.
The foam pushing device of a kind of flotation device of the present utility model is characterized in that the diameter that described taper pushes away the last frustum plane of foam is 2/3 of a flotation device cell body diameter, and the diameter on following frustum plane is 1/8 of a flotation device cell body diameter, and cone angle Zhang Du is 55～60 °.
The foam pushing device of a kind of flotation device of the present utility model is characterized in that the water spraying direction of hole for water spraying of described annular spray pipe and the angle of vertical direction are 30 °～45 °.
The foam pushing device of a kind of flotation device of the present utility model is fixedly connected by three cradling pieces and cell body.In floatation process, the taper that is arranged on flotation cell top pushes away foam makes the concentrate foam when rising to taper and push away the foam bottom, run into taper and push away the flat resistance of foam, prolonged foam sorting the time to mineral, and make its constantly upwards enrichment along inclined-plane of cone, fully adsorb the valuable metal in the ore pulp, the concentrate foam of the enrichment of constantly rising finally pushes in the outer shroud foam tank.The shower on the utility model top is directly managed access recirculated water by the shower water water inlet pipe through its top, recirculated water charges into and produces certain pressure in the circular spray tube, water is penetrated along the pinprick hole under the shower side, the size of regulating penstock makes the water column of ejaculation just be washed into peripheral annular foam tank, and the concentrate foam that deposits is constantly poured the concentrate discharge pipe.
The foam pushing device of a kind of flotation device of the present utility model, effectively prolonged the absorption of foam to valuable metal, make its constantly upwards enrichment of inclined-plane along cone, and the concentrate foam stabilization pushed the outer shroud foam tank, all pour the concentrate outlet by the shower water column at last, sort process thereby reach balance, stablize the purpose of concentrate foam output and raising concentrate sorting index.

The specific embodiment
A kind of foam pushing device of flotation device, the structure of this device comprises: taper pushes away foam 1-should push away the seal chamber that foam is an inverted taper type structure; This sparge pipe of annular spray pipe 2-has hole for water spraying 6 for to push away the isometrical ring pipe in foam epicone table top limit with taper on ring pipe; This water inlet pipe of shower water water inlet pipe 3-is that a water inlet end vertically is connected in the siphunculus on the annular spray pipe.
The utility model is welded to form by a conical thin-wall and the circular plain plate that a steel plate bends, and the lower end is the osculum of the vertex of a cone, and circular plain plate and osculum welding make the beneath end sealing of back taper.During flotation, the concentrate bubble of absorption valuable metal constantly floats in the ore pulp, rise to the superiors of cell body, in the process that rises, run at the bottom of the awl that taper pushes away foam, constantly upwards enrichment of inclined-plane at the bottom of the awl of annular, be pushed at last in the outer shroud foam tank, after shower inserted recirculated water, the pressure that is produced by recirculated water sprayed water column along the pinprick hole under the shower side, regulate the size of circulating water flow, shower is transferred to be sprayed onto the outer shroud foam tank just.
A kind of plug-flow device of the present utility model is by the welding that is uniformly distributed along the circumference of 4 one-tenth of three cradling pieces, connects by bolt at last to link to each other with flotation device cell body journal stirrup 5, and connection highly exceeds cell body 100～120mm.Cone upper brace diameter is about 2/3 of a cell body diameter, and the lower platform diameter is about 1/8 of a cell body, and wherein the cone angle Zhang Du of cone is 55～60 °.
