The device can perform online regulation of the scraping boards with big wearing capacity, guarantee the cleaniness of the roller surface, realize even material feeding and thus ensure the overall quality of the sintered ore.
Description
Technical field
The utility model relates to a kind of roll surface cleaning device that is used for field of metallurgy, relates in particular to a kind of round roller surface cleaning apparatus that is used for the sintering process flow process.
Background technology
Circle roller material scraper is meant and strikes off the device that sticks to compound on the round roller distributing device circle roller.On the sintering process, sinter mixture is to leave reflecting plate by the round roller that rotates, and requires whole cloth even, could guarantee yield and quality.Owing to adhere to compound on the circle roller, cause cloth inhomogeneous.Therefore, at the circle roller discharging opening back side material scraper need be installed and remove, guarantee that circle roller roll surface is clean, thus evenly blanking.
At present the device that adopts of sintering industry as shown in Figure 1, wherein a is a material scraping plate, b is the circle roller, c is a fixed support, d is a stud.This device is at circle roller back side mounting and fixing bracket, and fixing sheet rubber on the support is close to round roller surface by sheet rubber, carries out scraper.But there is the problem of two aspects in this technology: one, justify the roller rotating speed usually at 230 ~ 260r/min, because the sheet rubber quality is soft partially, through be bonded at round roller on sizing contact, the rate of wear is fast, require to change in the week, otherwise sheet rubber and circle roller spacing increase, and buildup is continued on circle roller surface, and sintering feed is had a negative impact; Two, owing to can't carry out online adjustment to the sheet rubber of wearing and tearing and change, can only be at shutdown operation, usually outage period be 3 months once, in this cycle, can't solve the influence that round roller surface buildup causes sintering feed.Indivedual enterprises also increase the wetting both sides of dripping device compound and strike off both sides sizing situation in mud roller both sides.But there are two problems at present: one, observe and find, because in each length range of 10% of circle roller two ends, sizing is serious more than other positions, so on the same horizontal plane, the friction of two ends steel plate and circle roller is middle violent, the steel plate wearing and tearing are also more serious, and the adhesion compound is more, and is unfavorable to sintering feed; Two, adopt the wetting meeting of dripping device to make the both sides mixture moisture content be higher than other positions, the both sides gas permeability is very good, destroys the uniformity of the bed of material.
What domestic manufacturer generally used is first kind of device, and the company that has does not even establish this type of device, causes a lot of companies circle roller surface buildup serious.
Summary of the invention
The purpose of this utility model provides a kind of round roller cleaning device, can the big scraper plate of online adjustment wear extent, guarantee that circle roller roll surface keeps totally realizing even blanking at any time, thus the total quality of assurance sintering deposit.
The purpose of this utility model is achieved in that a kind of round roller cleaning device, comprise fixed support, the horizon bar that is connected with fixed support, be fixed on the material scraping plate on the horizon bar, and the cramp bar that is used to support horizon bar and material scraping plate, described material scraping plate is at least three, be arranged side by side, the material scraping plate outside of both sides is cambered outwards arc.
Preferably, the formula of mathematical of described both sides material scraping plate radian is:
Preferably, all have the hole that is used to regulate the material scraping plate front and back position on the plate face of described material scraping plate.
Preferably, the described horizon bar that is connected with the both sides material scraping plate is two screw rods, and this screw rod is threaded with fixed support, and the hole on the material scraping plate plate face is a trapezoidal hole.
Preferably, the position that is connected with screw rod of described material scraping plate is provided with a square groove.
Preferably, the position of opening of described material scraping plate is covered with a cover plate, fixes by stud and cramp bar.
Preferably, the width of described middle material scraping plate accounts for the 75-80% of three material scraping plate beam overalls.
The utility model is owing to adopted above-mentioned technical scheme, make it compared with prior art, have following advantage and good effect: after the material scraping plate segmentation is provided with, adjust the position of material scraping plate according to different wear extenies, the plate face of both sides material scraping plate has radian, guarantee that circle roller roll surface keeps totally need not frequent replacing at any time, prolongation material scraping plate service life; Need not to shut down and change the material scraping plate that damages, but the direct-on-line operation.

Fig. 2 is an overall structure vertical view of the present utility model;
Fig. 3 is the front view of Fig. 2;
Fig. 4 is a left side of the present utility model material scraping plate enlarged diagram.
The specific embodiment
Shown in Fig. 2,3, this device comprises a fixed support 1, has two screwed holes in the left and right sides of fixed support 1, and four horizon bars (being screw rod 2 in the present embodiment) pass wherein respectively.The right-hand member of screw rod 2 stretches into respectively in the square groove set on the scraper steel plate 3 of the left and right sides, by rotary screw 2, thereby controls moving horizontally of left and right sides scraper steel plate 3.All have the hole that is used to regulate scraper steel plate front and back position and left rotation and right rotation on the plate face of left and right sides scraper steel plate 3, this hole is a trapezoidal hole in the present embodiment.Excessive for preventing because of set trapezoidal hole, can't directly tighten with bolt, the position of opening of scraper steel plate 3 all is covered with a cover plate 4.Scraper steel plate 3 is placed on the top of a cramp bar 5, fixedlys connected with fixed support 1 in the left side of cramp bar 5.Fixedly connected between cover plate 4, scraper steel plate 3 and the cramp bar 5 by stud 6.Wear extent on the contact-making surface of scraper steel plate 3 and circle roller 7 is different, wear extent near circle roller 7 both sides of the edge is inboard about 2.5 ~ 3 times, so scraper steel plate 3 is an arc near circle roller 7 edges one side, to guarantee still to cover the whole length of circle roller after material scraping plate advances.As shown in Figure 4, AC=50mm wherein, circle roller total length is L, BE=10% * L, BC=30mm, OC=2.5 OE=OE+BE-BC, so OE=(BE-BC)/1.5, by Similar Principle of Triangle, calculating this orphan's shape angle is Arctg[3AC/5 (BE-BC)], i.e. Arctg[30/ (0.1 * circle roller length overall-30)].
Shown in Fig. 2,3, also be provided with a scraper steel plate 8 at the middle part of circle roller 7, the width of this scraper steel plate 8 accounts for the 75-80% of three scraper steel plate beam overalls.In the present embodiment, the width ratio of three blocks of scraper steel plates is 1: 8: 1.Have three holes that are used to regulate front and back position on the scraper steel plate 8, the moving horizontally of scraper steel plate 8 only need be unclamped bolt and just be knocked and can realize with iron staff.Scraper steel plate 8 is placed on the top of three cramp bars 5, and both are fixedly connected by stud.Left and right sides scraper steel plate 3 and scraper steel plate 8 are positioned on the same level position, also can regulate the elasticity of this three on the upright position respectively according to actual conditions.Scraper steel plate 8 is basic identical with the wear extent of justifying on roller 7 contact-making surfaces, so scraper steel plate 8 is rectangle, its left end does not have the square groove.
