Abstract

The utility model relates to an inspiration-type stirrer which comprises a wheel hub and a plurality of stirring blades arranged along the periphery of the wheel hub; and a baffle is respectively arranged on the upper side and the lower side of the stirring blades. The inspiration-type stirrer is characterized in that an air inlet extending upwards along the axis direction is formed at the axle center of the baffle on the upper side; the air inlet is communicated with the space formed by the baffles on the upper side and the lower side; and the aperture of the lower end of the air inlet is larger than the inner diameter of the wheel hub. The inspiration-type stirrer is mounted on the gas-liquid division surface of a container; and under the rotation and centrifugation action of the stirring blades, an inspiration port at the upper end of the baffle on the upper side directly sucks air to be among the stirring blades, and the air is dispersed in the liquid through the stirring blades, so that the phenomena that the suction force is reduced when the air passes through a hollow stirring shaft, and fouling and blockage are easy to take place are overcome and eliminated. Under the condition of the same power consumption, the inspiration-type stirrer can improve the inspiration efficiency and reduce energy consumption.

Description

A kind of air suction type agitator
Technical field
The utility model relates to a kind of agitator, particularly a kind of air suction type agitator.
Background technology
At chemical industry, metallurgy, pharmacy, field of Environment Protection, a lot of technical process all need be carried out solution-air two-phase or gas-solid-liquid phase reaction operation, such as pressure leaching, hydrogenation, dissolved oxygen etc.This just need to use the air suction type agitator.Some air suction type agitators that use both at home and abroad at present, great majority are mounted in the darker bottom of container, and gas is by hollow shaft, by the negative pressure that the liquid in the air suction type agitator produces when rotation throws away, is inhaled in the liquid and mixes with it.Thisly realize that by hollow shaft there are the deficiencies such as easy fouling obstruction, gettering efficiency are low in air-breathing agitator.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides the air suction type agitator of a kind of gettering efficiency height, less scaling obstruction.
The technical solution of the utility model is: a kind of air suction type agitator, comprise wheel hub and along a plurality of paddles of wheel hub circumferential array, upper and lower both sides at paddle are provided with baffle plate, it is characterized in that: be provided with at the place, axle center of the baffle plate of upside along the axis direction air inlet of elongation upwards, the space that the baffle plate of this air inlet and upper and lower side forms interlinks, and the bore of air inlet lower end is greater than the internal diameter of wheel hub.
Described air inlet is the bell mouth shape that from bottom to top enlarges gradually.
The place, axle center of the baffle plate of described downside is provided with inlet.
Described paddle be shaped as arc or shaped form.
The beneficial effects of the utility model are: air suction type agitator of the present utility model is to be contained on the solution-air interface of container.Under the rotating centrifugal effect of paddle, the air entry of upper side shield upper end directly sucks gas between the paddle, is distributed in the liquid by paddle, overcome and when having eliminated gas by hollow shaft suction reduce the easy phenomenon such as fouling obstruction.Under equal power consumption condition, the gas formula agitator that the utility model is inhaled can improve gettering efficiency, reduces energy consumption.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, the embodiment of a kind of air suction type agitator of the utility model, comprise wheel hub 2 and along a plurality of paddles 1 of wheel hub 2 circumferential array, upper and lower both sides at paddle 1 are provided with baffle plate 4,3, wherein be provided with at the place, axle center of the baffle plate 4 of upside along the axis direction air inlet 5 of elongation upwards, this air inlet 5 interlinks with baffle plate 4,3 spaces 6 that form of upper and lower side, and the bore of air inlet 5 lower ends is greater than the internal diameter of wheel hub 2.Owing to establish air inlet 5, and the bore of air inlet 5 lower ends is greater than the internal diameter of wheel hub 2, thereby paddle 1 can directly be sucked into gas between the paddle from air inlet produce centrifugal force when stirring after, then be distributed in the liquid by paddle, so just greatly improve the gas suction efficiency, and the fouling choking phenomenon can not occur.
Air inlet 5 is preferably selected the bell mouth shape that from bottom to top enlarges gradually as shown in the figure.Can certainly adopt straight mouthful of shape.
As shown in the figure, in the present embodiment, also be provided with inlet 31 at the place, axle center of the baffle plate 3 of downside, can strengthen solution-air in mixing, the dispersion of agitator inside by this inlet 31; Certainly lower side shield also not opening namely form closedly, upper air entry only sucks gas, thereby reduces energy consumption.Do not establish in this lower end in the situation of inlet, agitator when mounted, the upper surface of the air inlet of upside need to be equal with liquid level or substantially equal, when stirring, can simultaneously liquid be sucked thus by air inlet like this, namely suck simultaneously liquid and gas by air inlet, thereby realize mixing and circulation.
The shape of paddle 1 can be arc or shaped form, also can adopt the various shapes such as straight chip or swept-back.
