Abstract
The invention relates to a method for continuously removing iron filings in a powdery material. The method is characterized in that a material flows from top to bottom along an inclined ramp; the inclined ramp is provided with an opening and a roller raising towards the inclined ramp is installed closely to an upper part of the opening; a part of the roller facing to the inclined ramp is magnetic and a part of the roller back against the inclined ramp is nonmagnetic; and an opening distance between the roller and the inclined ramp located at a lower side of the roller allows that a nonmagnetic powdery material passes through the roller and then freely falls off to the inclined ramp and iron filings adsorbed on the surface of the roller can be carried to the roller nonmagnetic part back against the inclined ramp by the surface of the roller and then freely fall off to an iron filing collection opening. The method provided by the invention has the advantages that according to a principle of magnet-based adsorption of iron filings, iron filings can be continuously separated from a powder flowing ramp; and a structure is simple and practical.
Description
Technical field
The present invention relates to a kind of method of from granular material, separating iron filings, method of separating in the material that especially can the irony material below the 30mm be flowed in pipeline.
Background technology
At present, cement and other exist the applied tramp iron separator of industry of material grinding that many types are arranged.The tramp iron separator that has is relatively heavier; The tramp iron separator permanent magnet that has is installed on the moving component, is prone to cause the permanent magnet vibrations to come off; The need that also have install other moving components in addition additional just can make the irony of removing out separate.All production has caused adverse effect to grinding for these.
Summary of the invention
In order better to solve irony isolated problem in material, a kind of granular material continuous deferrization bits method provided by the invention uses this method effectively iron filings to be separated from granular material.
The technical solution adopted for the present invention to solve the technical problems is: a kind of granular material continuous deferrization bits method; It is characterized in that letting material from a skewed ramp, from up to down flow through; On the ramp, open a gap; Be close to the top of gap and install one to the protruding cylinder in ramp, this cylinder is magnetic towards the part in ramp, and the part in ramp does not have magnetic dorsad; Gap spacing between cylinder and its downside ramp can make the granular material that do not have magnetic through under the free-falling behind the cylinder to the ramp, and the iron filings of cylinder surface absorption can take dorsad the ramp to cylinder surface and not have the drum segment of magnetic to be free to drop down to iron filings to collect mouthful.
Said cylinder two end axles center is provided with the support sleeve that extends laterally, and support sleeve is automatically connected on the central fixed shaft through bearing, is fixed with a drive pulley on one of them support sleeve; The two ends of said central fixed shaft are fixed on the bearing; The axial vane surface of said central fixed shaft is fixed with magnet to a side in ramp, the fixing resistance of opposite side magnetic plate washer.
Described magnet is permanent magnet, and the lateral surface of this magnet is curved and near inner wall of rotary drum.
Described resistance magnetic dividing plate is iron plate or corrosion resistant plate.Described magnet is permanent magnet, and the lateral surface of this magnet is curved, near inner wall of rotary drum.
Described resistance magnetic dividing plate is iron plate or corrosion resistant plate.
The cylinder that wear-resisting steel plate or stainless-steel sheet are made, cylinder can rotate under power drive, and second half space, the inside of the cylinder of permanent magnet and its installation separates with resistance magnetic sheet steel plate, and its purpose is to hinder magnetic.After this tramp iron separator device is installed on the material blanking scraper-trough conveyer; When material passes through; Start the cylinder of tramp iron separator, the irony in the material is adsorbed on the outer surface of cylinder by magnetic force, in the time of under its cylinder that is rotated brings to; Because the acting in conjunction of the weakening of magnetic force, centrifugal force and gravity realizes the separation of irony in material thereby irony breaks away from cylinder surface.
The invention has the beneficial effects as follows: utilize magnet absorption iron filings principle, can on a powder flows the ramp, iron filings be separated continuously, simple and practical.

The specific embodiment
A kind of granular material continuous deferrization bits method; On a powder flows the ramp, a grinding machine is installed and is used the pipeline tramp iron separator; It comprises bearing 6, cylinder 1; Said cylinder 1 two end axles center is provided with support sleeve 4, and support sleeve 4 is automatically connected on the central fixed shaft 2 through bearing, is fixed with a drive pulley 8 on one of them support sleeve 4; The two ends of said central fixed shaft 2 are fixed on the bearing 6; An axial side of said central fixed shaft 2 is fixed with permanent magnet 7, and fixing block plate of opposite side or corrosion resistant plate are as resistance magnetic plate washer 9; The lateral surface of described magnet 7 is curved, near inner wall of rotary drum.
In the embodiment shown in fig. 3, tramp iron separator is installed in the below of material blanking scraper-trough conveyer, under the situation of tramp iron separator cylinder work; When the material in the blanking scraper-trough conveyer through the time, the irony in loose, the material that flows is attracted on the surface of cylinder near material, after irony rotation that cylinder surface is adsorbed surpasses under the cylinder; The irony that cylinder surface is adsorbed along with magnetic force weaken and the effect of centrifugal force and gravity under; Break away from the blanking scraper-trough conveyer that falls into tramp iron separator with cylinder, the irony in the blanking scraper-trough conveyer of tramp iron separator is deposited a certain amount of, and turnover panel material air-valve is opened; Irony falls in the container of tramp iron separator below, accomplishes the iron work that removes.
