Abstract
The utility model discloses a roller surface cleaning scraper device. The roller surface cleaning scraper device is arranged on a roller and comprises a base arranged on the roller, a scraper fixedly disposed on the base and a base driving device connected with the base. The base is driven to rotate around a hinge joint so that the scraper fixedly connected with the base can leave or touch a surface of the roller. The tail end of a supporting frame is fixedly connected with the base. When the shape structure of the supporting frame is the same as that of the scraper touching the surface of the roller, the surfaces of the supporting frame,the surfaces of the scraper and the surface of the roller between the supporting frame and the scraper surround a closed area along the circumferential direction of the roller, and a purging end of a purging pipe is fixedly disposed inside the closed area.
Description
Technical field
The utility model relates to a kind of metallurgical servicing unit, relates in particular to a kind of doctor blade device that is used for roll surface cleaning.
Background technology
In production field of metallurgy, the various roller surfaces that are used for the compressive zone steel usually can adhere to foreign matter, in order to guarantee the surface quality with steel, need clean these rollers.For example, during continuous annealing coating unit ordinary production, jockey pulley, slewing rollers can adhere to foreign matter, produce periodically roll marks with band steel extruding back.When the roller ordinary production turned round, manual work can't be removed roll marks, needed to shut down to handle.
The method labour intensity that this shutdown is handled is big, and downtime is long, the more important thing is very big potential safety hazard, and security incident takes place easily.
For some rollers that very is prone to adhere to foreign matter, can be provided with the clear roller arrangement of scraper on it in addition, after roll marks occurring, scraper comes into operation, and removes the foreign matter on the roll surface, thereby reaches the purpose of eliminating roll marks.The clear roller arrangement of existing scraper is installed in the bottom of roller, and the foreign matter that is struck off relies on deadweight to break away from the body of roll, gets final product if there is the band steel bottom then adds the attaching ash-pit.But; Intermediate calender rolls P for " U " type three-roller type idler roller as shown in Figure 1; Because scraper can only be installed in the first half of this roller, in view of the structure of existing scraper, the foreign matter of being wiped off can amass the position that contacts with scraper at roller all the time like this; Can't clear out of the body of roll, these foreign matters that can't clear out of the body of roll can cause secondary pollution again.
Summary of the invention
The purpose of the utility model provides a kind of roll surface cleaning doctor blade device, and it is installed on the roller, even can realize it is installed in roller top, also can the foreign bodies removal that scrape be gone out the body of roll, prevents to cause secondary pollution.
In order to realize the foregoing invention purpose, the utility model provides a kind of roll surface cleaning doctor blade device, and it is installed on the roller, comprising:
One base, it is arranged on the said roller;
One scraper, it is fixedly set on the said base;
One base drive unit, it is connected with said base, drives said base and rotates around a pin joint, so that the scraper that is fixedly connected with said base leaves or the touch roll sub-surface;
One bracing frame; Its tail end is fixedly connected with said base; The shape of support frame as described above is configured to when said scraper touch roll sub-surface, support frame as described above, scraper and surrounded airtight closed area on the circumferential direction at roller jointly at the roller surfaces between bracing frame and the scraper;
One scavenging conduit, it purges end and is fixed in the said closed area.
Above-mentioned roll surface cleaning doctor blade device in use; At first driving base by the base drive unit rotates around pin joint; Thereby make the blade of scraper contact with roller surfaces, this moment bracing frame, scraper and surrounded airtight closed area on the circumferential direction at roller jointly at the roller surfaces between bracing frame and the scraper, along with the rotation of roller; Scraper can strike off the foreign matter that sticks to roller surfaces; These foreign matters are deposited in the closed area and can spill into other positions, and the scavenging conduit blowing gas goes out roll body with the foreign bodies removal in the closed area then.
Preferably, support frame as described above comprises:
A stationary plane that connects successively, an end face and a side, wherein said stationary plane is fixedly connected with base, and said side is provided with a vertical waist hole that is provided with;
One soft gasket which is provided with screwed hole;
One regulates bolt, and it runs through said waist hole and is threaded with screwed hole on the soft gasket;
In this embodiment, the lower end of said soft gasket and scraper, and roller surfaces has surrounded said closed area jointly.Being provided with of soft gasket can be protected roller surfaces, prevents when roller turn the frictionally damage roll surface of roller surfaces and bracing frame.In addition; Regulate bolt and make also that with the setting in waist hole the described roll surface cleaning doctor blade device of the utility model can be according to different roller situation; Regulate the relative position of soft gasket and bracing frame side, thus the tight touch roll sub-surface in the lower end of assurance soft gasket.
Alternatively, have two screws on the end face of support frame as described above; The purging end that one U-bolt, its two ends are walked around said scavenging conduit respectively with two corresponding connections of screw, with the purging end of fixing said scavenging conduit.
The described roll surface cleaning doctor blade device of the utility model is through adopting technique scheme; Overcome existing roll surface cleaning doctor blade device above being installed on roller the time; Can't remove the problem of the foreign matter that scrapes, thereby make that the set-up mode of roll surface cleaning doctor blade device on roller is more flexible.
Description of drawings
Come the described roll surface cleaning doctor blade device of the utility model is further specified below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is the structural representation of " U " type three-roller type idler roller.
Structural representation when Fig. 2 is in the inoperative station in one embodiment for the described roll surface cleaning doctor blade device of the utility model.
Structural representation when Fig. 3 is in work station for roll surface cleaning doctor blade device shown in Figure 2.
The specific embodiment
Fig. 2 has shown respectively that with Fig. 3 the roll surface cleaning doctor blade device in the present embodiment is in the state of inoperative station (leaving roll surface) and work station (contacting roll surface), and roll surface cleaning doctor device is located at the top of roller in the present embodiment.
After roll surface Q is stained with foreign matter and causes band roll marks appears in steel; The drive unit (not shown) drives base 1 and rotates around pin joint; Make scraper 2 from rotated position as shown in Figure 2 to position as shown in Figure 3; Be that scraper 2 contacts with roll surface Q, the source driving force of drive unit is the handle 3 of rotation in the present embodiment.
As shown in Figure 3, scraper 2 is fixedly installed on the base 1, and its tail end is fixedly connected with base 1, and its blade contacts with roll surface Q; Bracing frame 4 comprises stationary plane, end face and side; Wherein stationary plane is fixedly connected with base 1 through set bolt; The side is provided with the waist hole of vertical setting; Soft gasket 5 is connected with the side through regulating bolt 6, can regulate the height of soft gasket through adjusting the position of adjusting bolt 6 in the waist hole, the lower end of soft gasket 5 and scraper 2 and be positioned at roller surfaces Q surrounded jointly one on the circumferential direction of roller airtight closed area 7; The purging end 8 of scavenging conduit is fixedly installed in this closed area 7 through U-bolt 9, to purging in the closed area 7.
