Abstract
The invention discloses a residue return belt of a vertical mill. The residue return belt comprises a roller wound with a belt body, and the roller is made of permanent magnet materials. According to the residue return belt, the roller is arranged to be a permanent magnetic roller, irony residues in return residues of the vertical mill will be thrown away by inertia due to losing of polarity in the process that the irony residues in the return residues of the vertical mill are attracted by the roller to the belt body and move to a tail wheel, and wear-resistant parts such as a milling roller and a milling disc on the downstream are protected.
Description
Technical field
The present invention relates to Vertical Mill equipment technical field, especially a kind of Vertical Mill returns slag crust band.
Background technology
Current vertical mill system only has a set of deironing apparatus, irony foreign material are once enter and failing in mill to find in time to clear up, cannot crush again, can be circulated inside grinder system and repeatedly must mill through grinding roller and mill, and because irony foreign material hardness is higher, very easily wear parts is caused loss, raw material roller mill is gone into operation to only 1 year half time in April, 2010 in November, 2008, because of grinding roller serious wear, Vertical Mill unit-hour output is low carried out 3 large area grinding roll overlayings, built-up welding not only increases operation cost frequently, also have a strong impact on Vertical Mill to run well, restriction kiln plays its production capacity.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is proposed to a kind of Vertical Mill returns slag crust band, and structure is ingenious, and efficiency is high.
In order to realize foregoing invention purpose, the present invention provides techniques below scheme: a kind of Vertical Mill returns slag crust band, and including the cylinder being wound with belt, described cylinder is that permanent magnetism material is made.
Compared with prior art; the invention have the advantages that and cylinder is set to permanent magnetic pulley; Vertical Mill can be returned irony foreign material in slag and be adsorbed on belt in the process of tail wheel motion by cylinder, can be thrown away by inertia because of the gravitation that loses magnetism, protect the wearing piece such as grinding roller and mill in downstream.
Accompanying drawing explanation
Fig. 1 is the structural representation that Vertical Mill of the present invention returns slag crust band.
Detailed description of the invention
Describing the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, and protection scope of the present invention should not have any restriction effect.
A kind of Vertical Mill as shown in Figure 1 returns slag crust band, and including the cylinder 2 being wound with belt 1, described cylinder 2 is made for permanent magnetism material.
Vertical Mill returns the slag crust conveying with primary responsibility Vertical Mill scum, belonging to vertical mill system outer loop equipment, irony foreign material are conveyed into back slag elevator by time slag crust band again after being thrown away by mill in mill and return in mill, and this belt speed is fast, belt filled layer is thin, installs deironing apparatus additional at this comparatively suitable；Going back to slag crust band place at Vertical Mill and increase a set of deironing apparatus, the electromagnetic cylinder being about to back slag crust band transform the magnetic permanent magnetic pulley 2 of band as.
The main deironing parts of permanent magnetic pulley 2 are cylinders with permanent magnetism, and by driven by motor reductor, speed reducer drive is to belt.Irony foreign material are adsorbed on belt in the process of tail wheel motion by cylinder, can be thrown away by inertia because of the gravitation that loses magnetism, here it is the principle of permanent magnetic pulley deironing.
The effect that the present invention brings:
After having transformed; in April, 2010 is interim to the compliance test result in November, 2010; the irony foreign material that deironing cylinder is taken out of by group member are added up; average deironing every day 5 kilograms; and on June 10th, 2010 Vertical Mill powder classifier blade case accident; permanent magnetic pulley takes the blade come off out of Vertical Mill blood circulation, and for avoiding damage sequence to expand further, the protection wearing piece such as grinding roller and mill makes contribution.
By Vertical Mill being returned the transformation of slag crust band, not only increasing the deironing ability of vertical mill system, decreasing Vertical Mill built-up welding number of times, the stable operation of Vertical Mill unit-hour output can also be ensured, reduce production cost, be conducive to Dayao to produce normal, create certain economic benefit for company's production and operation.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
Claims (1)
1. Vertical Mill returns a slag crust band, including the cylinder being wound with belt, it is characterised in that: described cylinder is that permanent magnetism material is made.
