Abstract
Disclosed is an auxiliary fluidizing and separating device, belonging to component parts of a powder separator, aiming at solving the problem that current powder separators are not even in air distribution, which results in poor material separation effect, and the problem that the material is easy to collapse due to weak suspension effect from the air flow, which results in instability of the flow field of the system. The fluidizing and separating device comprises wind inlets arranged at two sides of the lower part of the lower cylinder body of the powder separator, and a fluidizing and separating box which is arranged at the lower part of the cylinder body of the powder separator, lower than the central line of the wind inlets. The fluidizing and separating box is composed of an air storage chamber, a nozzle which projects over the upper surface of the air storage chamber and is communicated with the air storage chamber, and an inlet pipe joint which is arranged at one side of the air storage chamber. The upper end of the nozzle is sealed and nozzle openings are arranged on the radial circumferential wall of the nozzle. The fluidizing and separating device is suitable to be used as a separating device for various wind plane vortex powder separators.

Technical field
The utility model belongs to the parts of powder concentrator, and particularly a kind of wind is swept the auxiliary flow that is used as of formula plane eddy current powder concentrator and divided diffusing device.
Background technology
Plane eddy current powder concentrator material dispersed is the key technology that its realization high efficiency is selected powder with the stability of selecting the powder flow field.Sweep in the air intake of eddy current powder concentrator bottom, formula fluidisation plane at existing wind, adopt air-flow to enter or enter usually, do not have the aid dispersion device from the both sides level from powder concentrator lower shell bottom vertical.There is following deficiency in such structure: from the bottom vertical air intake, cause the air-flow skewness easily, to the material dispersed weak effect; The horizontal air intake from both sides weakens the suspension effect of air-flow to material easily, occurs at feeding under the situation of fluctuation, and the material that collapses stops up, and causes system's flow field instability.
The utility model content
The purpose of this utility model be solve air-flow skewness that existing powder concentrator air intake exists and to material dispersion effect difference or air-flow to the suspension effect of material a little less than and the material that easily collapses stops up and causes system's flow field problem of unstable, a kind of auxiliary fluidizer that is used for powder concentrator is provided, can not only improve the airflow uniform distribution effect, keep powder concentrator lower shell flow field stable, and occur at feeding under the situation of fluctuation, also can adapt to adjusting automatically, the material that prevents to collapse stops up, and makes material dispersiveness and grinding efficiency be improved.
The purpose of this utility model realizes by following technical proposals:
Auxiliary flow is divided in bulk putting, comprise the air inlet that is arranged on both sides, powder concentrator lower shell bottom and be arranged on powder concentrator lower shell bottom, the fluidisation that is lower than the air inlet center line disperses case, fluidisation disperses case to be made of air storing cavity, the air inlet pipe joint that protrudes from air storing cavity upper surface and the nozzle that communicates with air storing cavity and be arranged at air storing cavity one side; The upper end closed of nozzle offers jet hole on its peripheral tube wall radially.
The distance of the upper end of described nozzle and air inlet center line is 20～400mm.
Described expansion box is that both sides are that camber line, both sides are the quadrangle of straight line, and the length of bow of its mean camber line is less than the length of straight line, and the path length between two camber lines equates with the internal diameter of powder concentrator lower shell.
Described nozzle is uniformly distributed in the upper surface of air storing cavity, can be 3～10 rows, and quantity is 10～150.
Described jet hole distributes along the even tube wall of nozzle, and quantity is 4～20.
Described fluidisation disperses case to be arranged with thick slag bucket, and the bottom of thick slag bucket is thick slag outlet.
The utility model is provided with fluidisation and disperses case in the powder concentrator lower shell, the air inlet pipe joint that this fluidisation is disperseed case with can be in air storing cavity after air compressor machine is connected the input pressure air, these forced drafts are discharged from the jet hole that the nozzle tube wall on the air storing cavity distributes then, gas channel is upwards formed at the bottom at the powder concentrator lower shell, when material fluctuates, the material that falls down can be suspended by the updraft that jet hole flows out, play the current-sharing effect, and employing has effectively been avoided the not good deficiency of vertical air intake dispersion effect from the both sides air intake mode of powder concentrator lower shell bottom; Air-flow that thick slag in the material, iron filings etc. can not be made progress holds up and falls into thick slag bucket and discharge; Jet hole is opened on the peripheral tube wall of nozzle, and the upper end closed of nozzle can effectively be avoided the fault of material with spray nozzle clogging.
As seen, adopt the utility model of said structure, compared with prior art, can not only improve the airflow uniform distribution effect, keep powder concentrator lower shell flow field stable, and occur at feeding under the situation of fluctuation, also can adapt to adjusting automatically, the material that prevents to collapse stops up, and makes material dispersiveness and grinding efficiency be improved, also have the effect of getting rid of thick slag, iron filings preferably, sweep in the eddy current powder concentrator of formula plane as dispersal device applicable to various wind.

The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, auxiliary fluidizer comprises the air inlet 6 that is arranged on both sides, powder concentrator lower shell 5 bottom, and be arranged on powder concentrator lower shell 5 bottoms, the fluidisation that is lower than air inlet 6 center lines disperses case 7, fluidisation disperses case 7 to be made of air storing cavity 2, the air inlet pipe joint 1 that protrudes from air storing cavity 2 upper surfaces and the nozzle 3 that communicates with air storing cavity 2 and be arranged at air storing cavity 2 one sides; The upper end closed of nozzle 3 offers jet hole 4 on its peripheral tube wall radially; Air inlet pipe joint 1 is connected with air compressor machine.
According to the difference of powder concentrator model, the distance between the upper end of the center line of air inlet 6 and nozzle 3 is chosen between 20～400mm, with not mutual interference and form the airflow field of upset mutually between the air-out of the air intake that guarantees air inlet 6 and the jet hole 4 of nozzle 3.
According to the difference of powder concentrator model, nozzle 3 is uniformly distributed in the upper surface of air storing cavity 2, can be 3～10 rows, and quantity is 10～150; Jet hole 4 distributes along the even tube wall of nozzle 3, and quantity is 4～20.
Select in the powder process, primary air enters from the air inlet 6 of both sides, powder concentrator lower shell 5 bottom, because suction function, primary air upwards flows, to the material suspended dispersed effect from the spout feeding.Simultaneously, air inlet pipe joint 1 on the air storing cavity 2 is connected with air compressor machine by tracheae, at the air storing cavity 2 inner certain pressures that form, jet hole 4 ejection air-flows from nozzle 3, form a suspended dispersed fluid bed on the top of air storing cavity 2, when feeding fluctuateed, unnecessary material can be floated by this fluid bed, effectively avoided influencing the stability in flow field, top, played the effect that improves material dispersiveness and grinding efficiency because the material that collapses stops up.
