Description
Technical field
The invention belongs to technical field of beneficiation, particularly relate to a kind of ore dressing mixture generator.
Background technology
At present, at gold mine, aluminium ore, bauxitic clay, iron ore, colliery, the mining industry ore dressing field such as rare-earth mineral, through ball mill ore pulp out by the extraction of liquid absorbing pump, mineralizer is entered again through piping, ore pulp passes through between two filter cores in mineralizer, simultaneously by air compressor machine pressurized gas out and topping-up pump, medicament is entered in mineralizer by two interfaces, and enter, by the filtration of two filter cores, the cavity that ore pulp flows through, ore pulp in this cavity, gas and medicament mixing, form a mixing section, then enter in the flotation cell that pipeline connects by the outlet of mineralizer, carry out the sorting of downstream. owing to existing mineralizer life cycle is short, and change cost height (production line needs 3--4 flotation cell, and a flotation cell needs six mineralizers), change also very loaded down with trivial details simultaneously, one group six, having one to go wrong, production of should stopping is changed. and there is ore pulp, gas and medicament and mix uneven situation, the more energy also wasted by the air compressor machine that mixture operation uses and topping-up pump.
Summary of the invention
The present invention is in order to solve weak point of the prior art, it is provided that a kind of structure is simple, the ore dressing mixture generator that mixes, reduce energy consumption.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: ore dressing mixture generator, comprise cylindrical circular shell, coaxial in shell it is provided with ore pulp pipe, annular cavity is formed between outer casing inner wall and ore pulp pipe outer wall, feed cavity and discharging chamber in axial direction it is provided with in ore pulp pipe, the outlet of feed cavity is connected with the import in discharging chamber, feed cavity and discharging chamber are the little conical structure of outer imperial palace, the equal diameters of feed cavity exit end and discharging chamber entrance end, shell and ore pulp pipe sidepiece radially correspondence be provided with gas and liquid import, feed cavity is connected with gas and liquid import with the junction in discharging chamber, the gas of ore pulp pipe sidepiece and liquid import are the conical structure that outer imperial palace is little.
The sewage draining exit being connected with annular cavity it is provided with outside described outer casing underpart.
Described outer side two ends are respectively equipped with ring flange.
The axial length of described feed cavity is less than the axial length in discharging chamber, and the diameter of feed cavity entrance end is 2mm--1000mm, and the diameter of discharging chamber exit end is 2mm--1000mm, and the diameter of feed cavity exit end and discharging chamber entrance end is 1mm--900mm.
The diameter of described gas and liquid import exit end is 0.1mm--100mm.
Adopting technique scheme, the ring flange at the shell two ends of the present invention is tightly connected by bolt and gasket with the ring flange on liquid-inlet pipe and drain pipe respectively, forms an overall pipeline. Feed cavity and surface, discharging chamber arrange one layer of high abrasion resisting material, can effectively defend washing away of ore pulp like this.
Ore pulp enters in feed cavity at a high speed by the liquid absorbing pump on liquid-inlet pipe, owing to the outer imperial palace of feed cavity is little, exit end pressure increase in feed cavity forms a nozzle, due to the gas of ore pulp pipe sidepiece and the existence of liquid import, negative pressure is produced herein, automatically air and the confection for preparing being sucked by gas and liquid import enters in discharging chamber, owing to discharging chamber is also that (entrance end is little for a reducing cavity, exit end is big), pressure in discharging chamber reduces gradually, three kinds of media are made to carry out mixing (ore pulp, air and medicament blending form bubble), discharging chamber forms an of short duration mixing section, then flowed out by drain pipe, carry out downstream.
The present invention has following useful effect:
1, present configuration is simple, more easily at existing improvement of manufacturing line.
2, when shutting down owing to ore pulp pressure disappears suddenly, ore pulp can have been entered in annular cavity by gas and liquid import, just have impact on production if blocked, so the ore pulp in annular cavity to be cleaned out before producing by start by sewage draining exit.
3, hinge structure, it is possible to save one group of (six covers) mineralizer (cost-saving, to simplify production technique and flow process); Can also save as the gases used large-scale air compressor machine of mineralizer and booster electric machine (saving space and input cost).
In sum, present configuration is simple, scientific in principle, ore pulp, air and medicament can be made to admix fully, produce a large amount of micro-bubbles, bubble is made to contact fully with ore pulp mineral like this, touch opportunity also increases greatly, well makes bubble adsorb with ore particle selectively, thus realizes higher returns and efficiency.

Embodiment
As depicted in figs. 1 and 2, the ore dressing mixture generator of the present invention, comprise cylindrical circular shell 1, coaxial in shell 1 it is provided with ore pulp pipe 2, annular cavity 3 is formed between shell 1 inwall and ore pulp pipe 2 outer wall, feed cavity 4 and discharging chamber 5 in axial direction it is provided with in ore pulp pipe 2, the outlet of feed cavity 4 is connected with the import in discharging chamber 5, feed cavity 4 and discharging chamber 5 are the little conical structure of outer imperial palace, the equal diameters of feed cavity 4 exit end and discharging chamber 5 entrance end, shell 1 and ore pulp pipe 2 sidepiece radially correspondence be provided with gas and liquid import 6, feed cavity 4 is connected with gas and liquid import 6 with the junction in discharging chamber 5, gas and the liquid import 6 of ore pulp pipe 2 sidepiece are the conical structure that outer imperial palace is little.
Shell 1 lower outside is provided with the sewage draining exit 7 being connected with annular cavity 3.
Outside shell 1, two ends are respectively equipped with ring flange 8.
The axial length of feed cavity 4 is less than the axial length in discharging chamber 5, the diameter D1 of feed cavity 4 entrance end is 2mm--1000mm, the diameter D2 of discharging chamber 5 exit end is 2mm--1000mm, and the diameter D3 of feed cavity 4 exit end and discharging chamber 5 entrance end is 1mm--900mm.
