Particle sizes can be adjusted by the air quantity, a rotor structure and the rotary speed. The present invention which is widely applied to the drying method powder sorting for industrial materials, such as non-metallic minerals, new materials, etc., has the characteristics of power saving, compact structure, etc. The present invention simultaneously obtains fine powder of two or more than two particle sizes.
Description
Technical field
The present invention relates to a kind of dry method powder selection device that is widely used in industries such as nonmetallic ore, new material.
Background technology
Powder concentrator commonly used mainly contains centrifugal, cyclone type, rotator type, eddy current type etc. in the industry, its common feature is to utilize wind-force that material is blown from bottom to top, thicker material makes downward power fall into the meal district greater than the strength that makes progress owing to effects such as being subjected to gravity, centrifugal force, and fine powder then continues upwards to enter the fine powder district.These powder concentrators are equivalent to a single-deck screen, only sort qualified fine powder and underproof meal, so can not obtain the product of two or more granularity simultaneously.State Intellectual Property Office disclosed the three composition dividing powder separating machine of a kind of publication number CN1485149A on March 31st, 2004, from structure and goal of the invention, be that the material that will draw off in the ball mill mill is divided into fine powder, middle meal, meal, reduce effectively and cross the grinding phenomenon in the mill, this patent fine powder is certified products, and middle meal, meal are defective work and return grinding machine.
Summary of the invention
Purpose of the present invention is exactly for a kind of many grades powder concentrator that can obtain the product of two or more granularity simultaneously is provided.
The objective of the invention is to realize by following technical scheme.It is a vertical structure, is made up of bearing block, rotor part, inner housing, housing, whirlwind tube etc., it is characterized in that: the top that is bound up and is installed in housing is bored in bearing block and charging aperture, blanking; Rotor part is connected to each other by drive, power transmission shaft, rotor field spider, upper rotor part, lower rotor part, spreading disk etc. and constitutes rotatable integral body, and power transmission shaft is installed on the bearing block by bearing; Housing is made up of upper shell, lower house two parts, and discharging opening is arranged at the lower house bottom; Inner housing places in the housing, and by last inner housing, middle inner housing, blast pipe, gas deflector cone, inner housing is coupled to integral body down, the meal outlet is established in the bottom of following inner housing, and blast pipe does not communicate with it during by housing; The whirlwind tube communicates with the top of housing by the fine powder pipe, when the above whirlwind tube of two or two, the fines collection awl of centralized collection fine powder can be set.During work, wind is from blast pipe enters in the inner housing, rotor part rotates by drive and the drive unit connection that can regulate rotating speed, material enters the back from charging aperture and drops on the spreading disk by the blanking awl, spread graded region by spreading disk to inner housing, thick material is dominated owing to gravity accounts for outside meal outlet discharge machine, fine powder is then driven by gas and enters in the housing by lower rotor part, after placing the further classification of upper rotor part in the housing, elementary fine powder is collected the back by housing and is discharged from the discharging opening of lower house bottom, the most fine-graded fine powder enters the fine powder pipe with air-flow and carries out gas solid separation collection afterbody fine powder by the whirlwind tube, and gas is discharged from whirlwind tube top; Classification needs according to the fine powder grade are provided with one or more levels housing, and when multistage housing was set, bearing block and charging aperture, blanking awl were installed in the top of outermost layer housing, and grade is adjusted by air quantity, rotor structure and rotating speed.
Below in conjunction with the embodiment accompanying drawing the present invention is further described, embodiment is a vertical structure, and a housing selects the fine powder of two kinds of grades, and this is simple and the most the most frequently used a kind of.
Description of drawings
Accompanying drawing is an embodiment of the invention structure installation diagram.
Among the figure: the 101-charging aperture; The 102-bearing block; 103-blanking awl; The 201-drive; The 202-power transmission shaft; The 203-upper rotor part; The 204-lower rotor part; The 205-rotor field spider; The 206-spreading disk; The last inner housing of 301-; Inner housing among the 302-; The 303-blast pipe; The 304-gas deflector cone; Inner housing under the 305-; The 401-upper shell; The 402-lower house; 501-fines collection awl; 502-whirlwind tube; 503-fine powder pipe
The specific embodiment
As shown in drawings, the present invention is made up of bearing block, rotor part, inner housing, housing, whirlwind tube etc.Bearing block 102 is bound up with charging aperture 101, blanking awl 103 and is installed in the top of housing; Rotor part is connected to each other by drive 201, power transmission shaft 202, rotor field spider 205, upper rotor part 203, lower rotor part 204, spreading disk 206 etc. and constitutes rotatable integral body, and power transmission shaft 202 is installed on the bearing block 102 by bearing; Housing is made up of upper shell 401, lower house 402 2 parts, and discharging opening is arranged at lower house 402 bottoms; Inner housing places in the housing, and by last inner housing 301, middle inner housing 302, blast pipe 303, gas deflector cone 304, inner housing 305 is coupled to integral body down, the meal outlet is established in the bottom of following inner housing 305, and blast pipe 303 does not communicate with it during by housing; Whirlwind tube 502 communicates with the top of housing by fine powder pipe 503, and the bottom is provided with the fines collection awl 501 of centralized collection fine powder.During work, wind enters blast pipe 303 from M and enters in the middle inner housing 302 again, rotor part rotates by drive 201 and the drive unit connection that can regulate rotating speed, material enters charging aperture 101 backs from A and drops on the spreading disk 206 by blanking awl 103, spread graded region by spreading disk 206 to inner housing, thick material is dominated owing to gravity accounts for outside meal outlet B discharge machine, fine powder is then driven by gas and enters in the housing by lower rotor part 204, after placing the upper rotor part 203 further classifications in the housing, elementary fine powder is collected the discharging opening C discharge of back from lower house 402 bottoms by housing, the most fine-graded fine powder enters fine powder pipe 503 with air-flow from N and carries out the concentrated fines collection awl 501 that enters of gas solid separation collection afterbody fine powder from the D discharge by whirlwind tube 502, and gas is discharged from whirlwind tube top P; Grade is adjusted by air quantity, rotor structure and rotating speed.
