Description
Technical field
The utility model relates to a kind of fine particle separation equipment, specifically, is a kind of multistage flotation column.
Background technology
Gu flotation is the method for carrying out liquid-liquid, solid-liquid and solid-separation (ore particle, oil droplet etc.) by the difference of the Surface Physical Chemistry character of particle; The method is with the running medium of bubble as particle.FLOTATION SEPARATION is to carry out in the floatation equipment of special use, and floatation equipment is mainly by following several: agitation impeller flotator, air flotation post and split type flotation column.At present, flotation column commonly used in the engineer operation is split type flotation column, and it has, and the flotation column height is low, the flotation efficiency advantages of higher; But through long-term experiment and practice, also there is following shortcoming in split type flotation device: inspiratory capacity is restricted, and ore pulp mixes abundant not with gas, and the mineralising effect is bad; And do not have ad hoc level control or watch-dog in the splitter, ore pulp often occurs and overflow, to such an extent as to have a strong impact on engineer operation.
The utility model content
The purpose of this utility model is to overcome defects, provide a kind of overall structure simple, realize easily floatation equipment.
To achieve these goals, the scheme of the utility model employing is as follows:
The multistage flotation column, comprise mozzle, be arranged on the splitter of this mozzle lower end, and the head piece that goes out that is arranged on the splitter lower end, be provided with the suction muffler that is attached thereto by tube connector in the upper end of described mozzle, this suction muffler upper end is provided with an end and inserts its inner nozzle, and offer the air flow inlet that communicates with ambient pressure at suction muffler, and on the sidewall of described splitter, also be provided with liquid level sensor, described mozzle number is two, and the two level is set up in parallel and all links to each other with splitter.
Further, described mozzle lower end tangentially links to each other with the splitter side.
Further, described air flow inlet number is more than one, and all is positioned at the upper end of suction muffler.
Further, described tube connector is 5 to 12 with the cross-sectional area ratio of mozzle.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and with low cost, realization convenience;
(2) the utility model is provided with the suction muffler that is attached thereto by tube connector in the upper end of mozzle, this suction muffler upper end is provided with an end and inserts its inner nozzle, and offer the air flow inlet that communicates with ambient pressure at suction muffler, nozzle sprays high speed ore pulp with pressure, air flow velocity is little from the air flow inlet of suction muffler side is involved in, air and ore pulp jet enter tube connector and are taken away at a high speed by jet, thereby in suction muffler, form pseudo-vacuum state, and cause negative pressure, thereby more Air Entrainment is entered the jet operation area, it is gradually consistent when air arrives mozzle with ore pulp, and change the kinetic energy of fluid-mixing into pressure energy by mozzle, and air split be divided into minute bubbles, thereby form foam stream at mozzle; The breathing space of suction muffler is much larger than mozzle, and immobilized particles or oil droplet in the ore pulp and the minute bubbles split minute carry out sufficient mineralization at mozzle, guaranteed that effectively ore pulp is abundant with mixing of gas, its mixing efficiency is higher than traditional split type flotation column, mineralization is strong, and then has improved flotation efficiency;
(3) the utility model also is provided with liquid level sensor on the sidewall of splitter, and this liquid level sensor is connected with external attention device by holding wire, and it can monitor the height of liquid level in the splitter timely, has effectively avoided flow of slurry to overflow;
(4) so material is common common material on the market in the utility model, and it is simple in structure, low price, cost is very cheap, has established solid foundation for it promotes the use on a large scale;
(5) the mozzle number is two in the utility model, and the two level is set up in parallel and all links to each other with splitter, and according to actual needs, mozzle also can be set to three, four even more, and it is in order to improve flotation efficiency.
