The row's of pressure iron device in a kind of vertical mill, comprise the scraper component, transmission mechanism and the driver part that are connected, described transmission mechanism comprises approach switch, described approach switch comprises working position approach switch and inoperative position approach switch, and the operating position and the off-position that are all electrically connected and distinguish the described scraper component of corresponding control with described driver part, described driver part drives scraper component to stop the rotation in the time that the plane internal rotation of vertical transmission mechanism turns and be controlled at respectively operating position and off-position by described approach switch control by transmission mechanism.
As selection, described scraper component comprises the shovel material scraper and the deflector chute that are connected, and described deflector chute is connected with described transmission mechanism.
In such scheme, when work, scraper component will stretch into shovel material in material, and shovel material scraper itself is two-sided frayed, consumes fast; And that deflector chute only plays guide effect one side is frayed, consume relatively slow.Two parts can adopt different materials to manufacture and design, and it is convenient to change, and reduces waste of material, saves and manufactures and maintenance cost.
As further selection, between described shovel material scraper and deflector chute, be also provided with breaker bolt.
In such scheme, be provided with breaker bolt at shovel material scraper and deflector chute connection place, in the time that scraper is subject to resistance and is greater than setting value; breaker bolt is cut off; scraper is shunk back in deflector chute, and in protection scraper, support and mill, other equipment are not damaged, the iron equipment safety running of the row of guarantee.
As selection, described scraper component entirety is bucket shape.
As selection, described transmission mechanism comprises approach switch and triggers pointer, the power transmission shaft that drives described triggering pointer to pivot, supports spring bearing and the frame housing of described power transmission shaft, and described power transmission shaft is in transmission connection with described driver part and scraper component respectively.
In such scheme, transmission mechanism connects scraper component and driver part.By the extension of power transmission shaft, make driver part be arranged in the normal temperature environment outside apparatus casing, and, make drive end away from scraper stress point, realize good mechanics effect.Approach switch, realizes operating position and off-position electrical control, simple to operate.
As selection, described driver part comprises the reducing motor and the torsion seat that are connected, and described reducing motor is connected with described transmission mechanism.
In such scheme, driver part can be selected the defeated change one of large speed ratio reducing motor, and reducing motor torsion seat can be installed according to the in good time condition in scene, easy for installation.Driver part only, in the time of shovel material scraper switch operating state, just needs the short time to obtain electric work, and energy consumption is low.
The main scheme of aforementioned the utility model and each further selection scheme thereof can independent assortment to form multiple schemes, be that the utility model can adopt and claimed scheme.In the utility model, respectively select to get final product and main scheme and other selection any combination, those skilled in the art can understand there is multiple combination according to prior art and common practise after understanding the present invention program, do not do exhaustive at this.
Workflow of the present utility model: scraper component initial position is parked in inoperative position, in the time that needs are arranged ironworker and are done, driver part obtains electric, drive scraper component dextrorotation to go to operating position by transmission mechanism, working position approach switch obtains electric, driver part shuts down, and now scraper component stretches on mill blocking material ring inner side, starts enrichment scum inside blocking material ring on mill to force eliminating.When row's iron finishes, driver part obtains electric reversion, drives scraper component to be rotated counterclockwise to off-position, and inoperative position approach switch obtains electric, and driver part shuts down, and waits for lower task indication.
The beneficial effects of the utility model: be a kind of effectively the eliminating when expecting the reliable initiatively row of pressure of circle inner side enrichment scum and running iron device.Vertical Mill is introduced after this row's iron device, and the discarded steel slag grinding technique that is rich in scum is achieved, and has obtained good economic benefits.Because enrichment scum on mill obtains effectively, gets rid of timely, the attrition that greatly reduces lining board for grinding discs and grinding roller roller shell, has reduced main frame energy consumption, has greatly improved equipment operation reliability, the application of having widened vertical roller grinder, has a wide range of applications.
