A vortex board is arranged in the barrel body, a guide blade is arranged in the vortex-shaped barrel body, the lower end of the main shaft is provided with a dish-shaped material spreading disk, the lower part of the vortex-shaped barrel body is provided with a coarse powder collecting device and a discharge pipe, the periphery of the barrel body is provided with a whirlwind barrel which is connected with an air outlet pipe, and the lower part of the whirlwind barrel is connected with a fine powder collecting device. The utility model has uniform material spreading performance, strong dispersion force, stable grading field, long powder selecting zone and multiple grading time.
Description
The utility model relates to a kind of device of solid being separated from solid with air-flow, specifically, is a kind ofly to transmit solid material with air-flow, or solid material is diffused in the device that carries out sorting in the air-flow.
Existing powder concentrator mainly contains two kinds: centrifugal classifier and cyclone type powder sorting machine.Centrifugal classifier, though its material that drops on the spreading disk spreads cross section to separation chamber with equally distributed material curtain form, but form a certain amount of materials flow inevitably on the material curtain, this materials flow can only partly be dispersed by ascending air, remainder is fallen in the meal with becoming thigh, thereby the incomplete phenomenon of sorting occurs.Because material is spread to barrel, so there is a lot of thick, fine powder to lose kinetic energy after bumping against barrel, slide along barrel, can not be by the updraught classification, cause the leakage choosing of fine powder, air circulates in airtight system in the powder concentrator, so fines concentration increases in the circulated air, because the fine powder sedimentation capacity is poor, be entrained in airborne fine powder and have only on a small quantity and be released, so the ability that air is carried more solid particles secretly reduces.If the increase circulated air will make the fine powder internal circulating load along with increase.In addition, in the turning between wind isolation board and the inner barrel, form local eddy currents, make fine powder in time not be drawn onto exocoel and be sorted out, thereby influenced grinding efficiency.For cyclone type powder sorting machine, though adopting the whirlwind tube to collect fine powder, it has reduced thickness powder inconsistent phenomenon,, it is improved by centrifugal classifier, also has the shortcoming of above-mentioned centrifugal classifier inevitably.
The purpose of this utility model is to provide that a kind of spreading disk spreading is even, dispersion force is strong, the classification field is stable, powder-separating area is long, classification eddy current powder concentrator often.
Technical solution of the present utility model is:
A kind of eddy current powder concentrator, comprise cylindrical shell, main shaft is equipped with on cylindrical shell top, the device that links to each other with motor is equipped with in the main shaft upper end, the volute tube is equipped with in the cylindrical shell bottom, the meal gathering-device is equipped with in volute tube bottom, under the meal gathering-device discharge duct is arranged, around the cylindrical shell whirlwind tube is housed, the whirlwind tube is connected with discharge pipe, the whirlwind tube is connected with the fines collection device, it is characterized in that: dish-shaped spreading disk is equipped with in the main shaft lower end, and coaxial superimposed flow plate is housed in the cylindrical shell, and each superimposed flow plate all is the garden ring-type, and garden girth is equipped with guide vane greater than following garden girth in the volute cylindrical shell on it.
The volute tube that guide vane is housed has two air inlets, can certainly be with the air inlet of or other suitable quantity.Liner plate is housed on the spreading disk, and the liner plate middle part is fixedly connected with the cutting plate of involute shape.Certainly, also can not adorn liner plate and cutting plate on the spreading disk.
The utility model can make material be uniformly dispersed, fully, and rotation gas forms laminar flow by the positive action of superimposed flow plate, makes the classification field stable, the classification head of district, sorting often, grinding efficiency is up to more than 80%.Owing to do not have rotary body in the flowing gas, and gas is to be horizontally through the material curtain, need not to promote powder, so power consumption is and simple in structure than lacking more than 20% with the output cyclone separator, production cost is low.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the configuration diagram of an embodiment of the utility model,
Fig. 2 is the configuration diagram of spreading disk among Fig. 1,
Fig. 3 is the structure chart of volute tube among Fig. 1,
A kind of eddy current powder concentrator, cylindrical shell 22 upper inside wall are equipped with shock plate 3, be fixed with a plurality of (generally using 3～5) superimposed flow plate 1 by cramp bar 2 on the inwall of cylindrical shell 22, superimposed flow plate 1 is the garden ring-type, and garden girth is greater than following garden girth on it, be to have angle between the bus of superimposed flow plate 1 and horizontal line, this angle with than material angle of repose big 15～20 ° be good, channel-section steel base 5 is fixed on the top of cylindrical shell 22, bearing block 7 is housed on the channel-section steel base 5, main shaft 6 is fixed in the bearing block 7, belt wheel 8 is equipped with in main shaft 6 upper ends, and dish-shaped spreading disk 4 is equipped with in main shaft 6 lower ends, and promptly the outer peripheral portion of spreading disk 4 has upwards been lifted up, liner plate 23 is housed on the spreading disk 4, and liner plate 23 middle parts are welded with the cutting plate 24 of involute shape.Motor is fixed on the channel-section steel base 5 by motor cabinet 13, and belt wheel 11 is housed on the motor 12, between belt wheel 11 and the belt wheel 8 by being with 10 transmissions.Volute tube 16 is equipped with in the cylindrical shell bottom, and guiding fan blade 17 is fixed on the volute tube 16, and the volute tube has two air inlets 25,26, and meal aggregate bin 18 is equipped with in volute tube bottom, and the meal aggregate bin has discharge duct 21 18 times.Have the whirlwind tube 15 of four or six or other suitable number to be connected with it around the cylindrical shell 22, whirlwind tube 15 tops are connected with discharge pipe 14, and the bottom of whirlwind tube 15 is connected with fine powder aggregate bin 20, is fixedly connected with supporting base 19 on the fine powder aggregate bin 20.
Operation principle of the present utility model is: the powder for the treatment of sorting is gone into spreading disk 4 from charging aperture 9, powder process spreading disk centre cutting plate 24 and action of centrifugal force are to disperseing all around, because spreading disk is dish, so powder is thrown evenly obliquely during by the surrounding and is spread out, after powder is dished out, hit on shock plate 3, be equal refining curtain then and fall into the branch constituency, blower fan is sent into a part of wind from air inlet 25, be the eddy current shape through guide vane 17 then and enter the branch constituency.Secondary wind (by grinding machine next wind or ambient wind) is sent into from air inlet 26.It has strengthened air whirl, and secondary wind rises with a wind eddy current and enters the branch constituency.Because the draft of blower fan, gas is eddy current on one side, to flowing over, pass the material curtain all around on one side, fine powder is sorted out from meal, fall on the superimposed flow plate 1 through the powder of a sorting, flow to up and down between the two laminated flow plates from the superimposed flow plate again, the gas sorting of being crossed again, fine powder is taken away with gas, meal is fallen on the superimposed flow plate, repeats a process then.Powder from top to bottom, through three to five times air-flow rinsing, fine powder is selected fully, is collected in whirlwind tube 15 down, meal falls into fine powder aggregate bin 18.Gas after fine powder separates sucks blower fan, and blower fan is sent a gas part that sucks to powder concentrator, and a part is sent into electrostatic precipitator, and the fineness of product can be regulated by the air quantity of adjusting blower fan.
