Abstract
The utility model discloses a stirring impeller with air holes arranged in the back of each blade. The stirring impeller with the air holes arranged in the back of each blade is composed of a hollow shaft and a plurality of hollow blades, wherein the plurality of hollow blades are installed on the hollow shaft, a air-hole-connecting group is arranged in a joint part of the hollow shaft with each blade, and the inner space of each hollow blade is communicated with a center hole of the hollow shaft through each air-hole-connecting group. An air hole group is arranged in a back side of the tail portion of each hollow blade, and each air hole group is communicated with the center hole of the hollow shaft through each hollow blade and each air-hole-connecting group. The center hole is sealed off through an end enclosure at the bottom end of the hollow shaft. According to the stirring impeller with the air holes arranged in the back of each blade, air is supplied through the air holes arranged in the back side of the tail portion of each hollow blade. A power dissipation of the supplied air is reduced due to the facts that negative pressure formed in the back side of each hollow blade or the pressure is reduced when an impeller is rotating. The hollow blades are both a stirring device and an air distribution device. Due to the fact that the air is supplied while the hollow blades are in rotation motion, formation of smaller air bubbles is facilitated. The air bubbles are rather evenly distributed in ore pulp, and the dispersity of the air bubbles is improved.
Description
Technical field
The utility model relates to the agitator arm of mechanically stirred reactor, relates in particular to the agitator arm that a kind of ore pulp that contains solid mineral grain for biological metallurgy and hydrometallurgy passes into the mechanically stirred reactor that gas reacts.
Background technology
Many courses of reaction need to pass into gas.The reactor that passes into gas is of a great variety, can be divided into airlift reactor, injection-type reactor and mechanical stir-reactor by working method, but in the actual production in biological metallurgy and hydrometallurgy field, what the most widely use is mechanical stir-reactor.
The impeller of tradition mechanical stir-reactor is positioned at below the middle part of reactor liquid level, gas distributor is positioned at the reactor base plate vicinity of impeller bottom, gas enters in the ore pulp in the reactor through breather pipe and gas distributor, and the stirring action of impeller makes gas dispersion become bubble.The gas pressure that passes into must greater than the venthole place hydrostatic pressure of gas distributor in the reactor, just can make gas overflow from the gas distributor venthole and enter the ore pulp solution.The static pressure of liquid is directly proportional with the degree of depth of liquid and fluid density, and the specification of industrial reactor is large, the height of the large-scale reactor that has reaches more than the 10m, the density of ore pulp is also larger in addition, the gas distributor venthole place hydrostatic pressure of traditional reactor is large, therefore needs with blower fan (gas compressor or air blast) to the reactor supply gas.The pressure of blower fan supply gas is larger, and the energy consumption that feeds unit mass gas is just larger, so the power consumption that feeds gas of traditional reactor is large.To feed gas more for unit ore pulp volume in addition, and the air feed power consumption of unit ore pulp volume is larger.For the course of reaction of a large amount of ventilations of needs, the power consumption of ventilation is very large, and the blower fan power consumption of air feed is the several times that stir power consumption generally speaking.For this reaction, improve structure of reactor, reducing supply gas pressure is energy-conservation important channel.In addition, the conventional impellers stirred reactor also has other shortcomings:
(1), since traditional mechanically stirred reactor with fixing gas distributor air feed, and the stirring action that relies on impeller breaks up bubble, the bubble spread is low, is unfavorable for improving gas effciency;
(2), gas distributor is installed in reactor bottom, is difficult to the cleaning dredging after stopping up;
(3), be easy to the fouling precipitation in the venthole of gas distributor, as adopting micropore or pore type gas distributor, the venthole of gas distributor is easy to be stopped up by the fouling precipitation, and the smooth or passage of ventilation is blocked fully.Therefore, have to adopt the gas distributor of large aperture passage, with impeller dispersed with stirring bubble.So, the disperse weak effect of bubble, gas effciency is low.
Pass into disperse effect and the gas effciency of gas in order to improve reactor, and reduce the energy consumption of reactor ventilation, be necessary impeller and the gas distributor of Improvement reactor.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of traditional reactor, and provides a kind of blade rear portion to be provided with the agitator arm of passage.The utility model reduces the power consumption of air feed blower fan to reduce the reactor supply gas pressure, improved gas dispersion degree and gas effciency.
The utility model is comprised of quill shaft and multi-disc hollow blade, the multi-disc hollow blade is installed on the quill shaft, junction with every hollow blade on the quill shaft all arranges the linked hole group, this linked hole group is communicated with the inner space of hollow blade with the centre bore of quill shaft, the afterbody back side of every hollow blade is provided with the passage group, and the passage group is communicated with the centre bore of quill shaft by hollow blade and linked hole group; The bottom of quill shaft is with end socket blocked center hole.
The beneficial effects of the utility model:
1, the utility model feeds gas by hollow blade afterbody back side passage, forms negative pressure or pressure at the hollow blade back side during because of vane rotary and reduces, and the power consumption that feeds gas reduces.
2, hollow blade be agitation means also be the distribution of gas device, because hollow blade feeds gas in rotatablely moving, be conducive to form less bubble, and bubble distribution is more even in the ore pulp, can improve the bubble spread.
3, because of after the hollow blade rear portion feeds gas, pressure differential reduces before and after the blade, and the vane rotary resistance reduces, and the power consumption of impeller-driven motor reduces.
