Abstract

The invention discloses an iron discharging mechanism of a vertical roller mill. The iron discharging mechanism comprises a mill stone and a grinding roller, wherein a scraper is arranged above a substrate of the mill stone and is connected with a knife rest through a screw, the outer end of the knife rest is fixed on a shell of the vertical roller mill, the front side surface of the scraper is opposite to the rotary direction of the mill stone, and is an inclined surface, the included angle between the inclined surface and a material blocking ring of the outer edge of the mill stone is an acute angle, and the outer side surface and the lower end surface of the scraper are respectively not in contact with the upper surface of the substrate of the mill stone. The iron discharging mechanism has the obvious advantages of good iron discharging effect and long service lives of the grinding roller and the substrate of the mill stone.

Description

A kind of Pai Tie mechanism of vertical roll grinder

Technical field:

The present invention relates to a kind of flour mill, particularly a kind of Pai Tie mechanism with the vertical roll grinder of row's iron function.

Background technology:

Vertical roll grinder instead of ball mill grinding steel mill at steel-making, the discarded object that produces in ironmaking processes owing to having energy-efficient remarkable advantage; slag, slag; but this vertical roll grinder in use expose cause because row's iron effect is bad overground; thus make grinding roller large end abradant surface and lining board for grinding discs large end abradant surface unstable wear; increase grinding roller and lining board for grinding discs wear-resistant surface Bead weld repair number of times and maintenance cost and downtime, become applying of restriction vertical grinding roller machine.

Summary of the invention:

The object of the invention is to provide a kind of Pai Tie mechanism of arranging the effective vertical roll grinder of iron.

The technical scheme realizing the object of the invention is, a kind of Pai Tie mechanism of vertical roll grinder, comprise mill, grinding roller, it is characterized in that: the top of described lining board for grinding discs is provided with scraper, described scraper is connected with knife rest by screw, the outer end of described knife rest is fixed on the housing of vertical roll grinder, the leading flank of described scraper is relative with the direction of rotation of mill, the leading flank of described scraper is inclined-plane, the described inclined-plane angle crossing with the collet of mill outer rim is acute angle, the lateral surface of described scraper and lower surface do not contact with the medial surface of collet and the upper surface of lining board for grinding discs respectively.

The present invention has the remarkable advantage of the effective and grinding roller of row's iron and lining board for grinding discs long service life compared with the prior art.

Accompanying drawing illustrates:

Fig. 1 is vertical roll grinder of the present invention row iron mechanism structure schematic diagram; Fig. 2 is the B place partial enlarged drawing of Fig. 1; Fig. 3 is the A-A profile of Fig. 2.

Detailed description of the invention:

In order to the defect that the row's iron solving existing vertical roll grinder exists, the present invention adopts following technical proposals, as Figure 1-3, scraper 6 is fixed on knife rest 5 by screw, the base 8 of this knife rest rear end is connected with vertical roller grinder engine housing 7 with screw or welding, the leading flank of described scraper is relative with the direction of rotation of mill 1, the leading flank of described scraper is inclined-plane, and be acute angle with the angle of collet 4 phase oblique, its effect is that the material on lining board for grinding discs is scraped mill, gap is had between the lower surface of described scraper and lining board for grinding discs 2, gap is had between the lateral surface of scraper and collet medial surface.Thus efficiently solve the wearing and tearing of ferric remains material to grinding roller 3 and lining board for grinding discs, improve grinding efficiency, extend the life-span of vertical roll grinder.

The present invention has only set up scraping mechanism at mill outer rim place, thus the material through grinding is routed up outside collet from lining board for grinding discs, and the mill of vertical roller mill, grinding roller, power set and transmission device, hydraulic loading device, rocking arm, material choosing apparatus is not done to change in mill.

Claims

1. the Pai Tie mechanism of a vertical roll grinder, comprise mill, grinding roller, it is characterized in that: the top of described lining board for grinding discs is provided with scraper, described scraper is connected with knife rest by screw, the outer end of described knife rest is fixed on the housing of vertical roll grinder, the leading flank of described scraper is relative with the direction of rotation of mill, the leading flank of described scraper is inclined-plane, the described inclined-plane angle crossing with the collet of mill outer rim is acute angle, and the lateral surface of described scraper and lower surface do not contact with the medial surface of collet and the upper surface of lining board for grinding discs respectively.
